Abstract:
A cigar shaped pipe, ideally made from premium materials such as briar, yet designed to be low cost to manufacture. The device uses a comparatively thin-walled combustion chamber, which both keeps material costs to a minimum, as well as an in-line reverse Calabash chamber to reduce the temperature and moisture of the smoke. In some embodiments, the pipe will further use an end cap, ether for pipe storage or during smoking This optional end-cap will ideally be made of the same materials as the main pipe body, and thus will have similar thermal expansion properties, as well as having the same beneficial combustion chamber properties. This end cap may utilize O-rings or screw threads to hold the pipe's end cap onto position, thus enabling easy loading and cleaning.
Abstract:
A seat belt retractor has a spool for carrying seat belt webbing rotatably mounted about a longitudinal axle and biased in a seat belt webbing rewinding direction. A toothed ratchet wheel is mounted to rotate with the spool. A sensor is provided for detecting an emergency condition, and a vehicle acceleration sensor lever is responsive to the sensor to engage the ratchet wheel in an emergency. The retractor can operate in a first, emergency locking mode in which the spool is not locked and can rotate to pay-out and to rewind seat belt webbing. In a second, automatic locking mode the spool is locked against pay-out of the seat belt webbing. A switching means has a subassembly attached to an end of the seat belt retractors. The subassembly has an axially directed spring to reduce axial spacing between the housing, an eccentric cam and axially adjacent disks.
Abstract:
A seat belt retractor (10) has an actuator (14) for unlocking and locking the seat belt retractor (10). An inertial sensor (18) detects changes in vehicle acceleration and interacts with the actuator (14) to lock and unlock the seat belt retractor (10). The inertial sensor (18) has one inertial sensor mass, each mass (26, 27, 29, 30, 32, 33) has a wide portion (70) and a narrow portion (72). Preferably each inertial sensor mass (26, 27, 29, 30, 32, 33) has a high density body (31) embedded in the wide portion (70) of the elastomeric material (34). The inertial sensor mass (26, 27, 29, 30, 32, 33) has a greater density than the elastomeric material (34). Moreover, the elastomeric material (34) at least partially surrounds an exterior circumferential surface (38) of the inertial sensor mass (26, 27, 29, 30, 32, 33). The inertial sensor mass (26, 27, 29, 30, 32, 33) has a body (31) having the wide portion (70) and optionally the narrow portion (72) with preferably one or more elastomeric protruding member (54, 58) extending from said body (31). The one or more protruding members (55, 58) are movable relative to said body (31) and soften contact rattle impacts thus reducing noise.
Abstract:
A tire tread having design cycles or pitches in which the circumferential lengths of repeated pitches are randomly modulated in certain selected sequences to reduce the amount of noise generated by the tire tread when the tire rolls on a road surface. The pitch sequences include three different circumferential pitch lengths including a group having a largest number of medium length (M) pitches, a smallest number of shortest length pitches (S) and a medium number of longest length (L) pitches. In one embodiment, the ratio of the three different pitches are 0.8 for the smallest length pitch (S), 1 for the medium length pitch (M) and 1.2 for the longest length pitch (L). 100 pitch sequences are proposed with the sequence L M S M S L M L M L M L M L M M L M L M L M L M L M being the preferred sequence which provides the most noise reduction. Ninety nine other pitches are also within a range to provide an acceptable level of noise reduction in a tire tread.

Abstract:
A cigar shaped pipe, ideally made from premium materials such as briar, yet designed to be low cost to manufacture. The device uses a comparatively thin-walled combustion chamber, which both keeps material costs to a minimum, and also enables a comparatively simple and easy to manufacture design. In a preferred embodiment, the pipe will not use metal parts or clips, but rather will use an end cap that is made of the same materials as the main pipe body, and thus will have similar thermal expansion properties, as well as having the same beneficial combustion chamber properties. This end cap utilizes a unique O-ring design to hold the pipe's end cap onto position, thus enabling easy loading and cleaning. This design also helps to prevent pipe cracking problems and loose part problems that can otherwise occur (due to differential thermal expansion) when metal parts are used.
Abstract:
A punch canister includes a punch head with an axial shaft that has a screw thread which is adapted to be connected during use to the screw threads of a punch element that is slideably associated within a stripper bushing. A punch recess adjustment member is rotatably and slideably associated with the punch head. The adjustment member is adapted to the slideably but non-rotatably rotatably connected during operation to the punch element. A resilient retraction member, e.g., a spring, is located between the punch head and the adjustment member for biasing the adjustment member axially downward on the punch head. A manually releasable detent provided on the adjustment member is operatively associated with the punch head for retaining the adjustment member in any one of a plurality of selected circumferentially distributed angular positions on the punch head such that during operation disengagement of the detent allows the adjustment member and the punch element to be threaded axially on the punch head to control the distance that the punch element is recessed within the stripper bushing. In a preferred form, the detent is a lock that can be disengaged manually when the punch recess adjustment is to be made.
Abstract:
A punch press alignment instrument has upper and lower cylindrical components that are associated for vertical displacement relative to one another. Both components have outer tool holder engaging surfaces which are to be aligned with one another so as to in turn align the tool holders of the punch press when the upper and lower components themselves are in alignment. Alignment elements, e.g., ridges and grooves provided on mating surfaces of the components confronting each other are brought into contact with one another to move the components of the instrument into mutual alignment. An alignment control member, e.g., a screw is preferably provided for progressively bringing the upper and lower components toward one another and an indicator such as a lamp, a dial indicator or an audible indicator is provided for denoting the spacing between the upper and lower components to thereby confirm the alignment of the tool holders. A releasable element is used to temporarily hold the upper and lower components apart when they are spaced laterally from one another or for any reason are not capable of being placed in alignment.

Abstract:
A punch assembly for punching or forming sheet metal has a circumferentially extending, horizontally disposed supporting flange that is slideably mounted upon the body of the punch assembly as a part thereof for supporting the punch assembly on a punch press. A resilient tool retractor, e.g., one or more springs is provided within the punch assembly for retracting or elevating the body of punch assembly relative to the supporting flange. Provision is also made for enabling a person to manually change the tool length and thus the feed gap from the exterior of the punch assembly by controlling the distance that the upper forming tool, i.e., the punch extends downwardly below the supporting flange and a lock is provided for securely retaining it in a selected position.
Abstract:
A seatbelt retractor assembly (10) has a seatbelt retractor (14) and an actuator (26) for locking and unlocking the seatbelt retractor (1). An inertial sensor mass (30, 32, 33) detects changes in vehicle speed. The mass (30, 32, 33) has a guide surface (34, 35, 36) for interacting with the actuator (26). The guide surface (34, 35, 36) moves between an unlocking position in which the actuator (26) unlocks the seatbelt retractor (14) and a locking position in which the actuator (26) locks the seatbelt retractor (14). The guide surface (30) has an inner profile portion (62) and at least an outer profile portion (64). The actuator (26) is in contact with the inner profile portion (62) in the unlocking position while moving into contact with the outer profile portion (64) as the actuator (26) moves towards the locking position. The inner profile portion (62) causes a different acceleration of the actuator (26) than the outer profile portion (64).
