摘要:
A golf shoe and golf club cleaning device particularly adapted for attachment to a golf bag or other convenient surface. The device includes a brush handle having soft bristles embedded in one face thereof and stiff bronze bristles embedded in an end wall that extends out of the general longitudinal extent of the handle at an angle thereto. The handle is tethered to a golf bag by a spring loaded cable that retracts into a casing and the cable is removably attached to a golf bag. By this arrangement, the brush is securely fastened to the golf bag or other convenient surface during normal play.
摘要:
A system for manually setting a timing value of an electronic fuze for an artillery projectile prior to firing without tools or electric power, and for displaying the set timing value in standard decimal format. Two adjacent setting rings, disposed about the outside of the fuze housing, are interconnected together with the housing so that one ring rotates with the other ring when the other ring is manually rotated in one direction about the housing axis, but is prevented from rotating when the other ring is rotated in an opposite direction about the housing axis. Each ring carries a plurality of numbers disposed about its outer periphery such that one of the numbers is axially aligned with an indication mark on the fuze housing at each setting of the ring. The two series of numbers are oriented laterally so that the two numbers aligned with the indication mark constitute the desired timing value. Also these two series of numbers are selected so that the indicated timing value can be manually adjusted in equal time increments from a minimum value to a maximum value, with the total number of selectable timing values being equal to the number of settings of one ring times the number of settings of the other ring. Each ring actuates a ring-type membrane switch assembly disposed between the ring and the fuze housing to encode a multi-bit code to the electronic fuze corresponding the indicated number of that ring.

Novel vinyl chloride copolymers including a hydroxyalkyl acrylate or methacrylate or allyl alcohol, an epoxy-containing vinyl monomer and an acid functionality from either certain carboxylic acid-containing monomers or a phosphorus ester moiety in selected proportions provide suitable binder resins for applications such as magnetic recording media, imparting desirable thermal stability together with enhanced dispersion and magnetic property characteristics and miscibility with elastomers employed in such media.
摘要:
Waterborne, neutralized, carboxyl-bearing phenoxy resin with which is blended a relatively soft, neutral, non-carboxyl-bearing modifier resin. A coalescing solvent is preferably included in the aqueous blend.
摘要:
Polyarylene polyethers composed of recurring units--O-E-O-E'--where E is the residuum of a dihydric phenol and E' is the residuum of a benzenoid compound having an inert electron withdrawing group ortho or para to the valence bonds and where both E and E' are bonded to the ether oxygens through aromatic carbon atoms. The polyarylene polyethers are prepared by reacting a double alkali metal salt of a dihydric phenol with a dihalobenzenoid compound in the presence of certain sulfoxide or sulfone solvents under substantially anhydrous conditions.

A remote monitoring system includes transducers, a transducer control module, a communications device, a monitoring system and end-user display terminals. The transducers are disposed on the property and/or equipment in a manner to measure specific characteristics or parameters and communicate with the transducer control module via a wireless communication protocol. The transducer control module receives and analyzes transducer measurements and detects alarm conditions. The transducer control module communicates with the monitoring system via a wide area network and the communications device. The monitoring system receives, stores and analyzes information received from the transducer control module and reports the information to the end-user terminals via a wide area network, such as the Internet, in response to user requests.
摘要:
A process for the polymerization or copolymerization of an olefinically unsaturated monomer which comprises contacting the monomer with a chromium metal catalyst composition which is the product obtained by adsorbing a chromium metal complex which contains allyl hydrocarbon radicals with an inert inorganic oxide support which has --OH groups on its surface and which is free from adsorbed water, said monomer being an olefinically unsaturated monomer other than a polar vinyl monomer.
摘要:
A recreational device which approximates the feel of downhill skiing without either skis or snow is described in which the device includes a rotatable outer tire and an inner ring which is carried by roller bearing means within the tire. The inner ring is provided with a pivotably mounted platform adapted to provide a foot support for an individual, with the platform in one embodiment including a backwardly projecting extension which serves as a stabilizing tail. An individual utilizing the recreational device is provided with a cross bar secured at waist level to the inner ring via a trapeze arrangement. The size of the ring/tire combination is such that its vertically extending height exceeds that of the largest individual to be accommodated when the individual is standing upright, such that the center of gravity of the ring/tire combination is well above the center of gravity of the individual, thereby creating stability and ease of turning. Back and forth oscillatory movement is controlled by virtue of the stabilizing tail and the entire ring/tire structure is made as light as possible so that a minimum amount of effort is required to overcome gyroscopic restorative forces.
摘要:
An acceleration actuated switch is disclosed which is capable of distinguishing between random and brief acceleration forces on the one hand and sustained acceleration forces on the other hand. The device comprises a stationary electrical contact and a movable contact held in position by biasing means. Sustained acceleration forces in a particular direction will drive the movable contact along a fixed path to a position whereat the biasing means may bring the movable contact into proximity with the stationary contact thereby closing the switch. If the acceleration force is not in the proper direction or is not applied to the switch for a sufficient length of time, the biasing means will return the movable contact to its original position thereby maintaining the switch in an open condition.
