Abstract:
Due to the fact that tying a tie is extremely bothersome there has been a desire for ties that can be quickly changed and can be worn on both sides. Also, ties have been fixed structures, difficult to make out of materials other than fabric. In the disclosed device, either the entire length or one section of a cord (41) is overlapping so that it is at least two ply. The cord (41), wherein either the entire length or one section is at least two ply, can be pulled out almost simultaneously. The pulled cord (41) extends out in opposite directions, enabling a loop (44) to be set to a flexible size, and enabling the easy formation of a loop larger than the object to be passed there through. Furthermore the large loop, created as described above, can easily be changed to a suitable size by use of a reel system with an inbuilt return-prevention mechanism.

Abstract:
A button provides an adhesive flat bottom surface for attachment to a cell phone or similar hand held device. A leash extends from the button and terminates with a finger ring. When the device is held in a hand with one finger secured in the ring, the device is secured in the hand so that it is less likely to fall. The ring may be an extension of the leash, both a part of an elastic cord loop where the leash is secured within the button and the ring extends away from the button- The leash may be retractable.
Abstract:
Preferred embodiments of the invention comprise an automatic reel capable assisting a user when attempting to unspool a linear material, such as a water hose. The automatic reel includes a control system (200) having a motor controller (224) capable of sensing a pulling of, or increased tension of, the linear material and capable of causing a motor (222) to rotate to unspool the linear material. In certain embodiments, the motor controller (224) tracks the length of the unspooled portion of the linear material and/or reduces the spooling speed of the motor (222) when retracting a terminal portion of the linear material.

Abstract:
A power cable reeler (108, 110, 120) including a cable reel (204) mounted on a movable base (210), the cable reel (204) being adapted to take up or deploy cable (206) as the movable base (210) moves. Also disclosed is a power cable reeler (112) adapted to feed a cable (126) over a rim of a mine high wall (124), the reeler (112) including an arm (114) mounted on a base, the arm (114) being inclined to project over the rim of the wall (124), the arm (114) being adapted (116) to support a cable (126) at the free end of the arm (114). A method of operating a mine having a workface using a mining equipment (102) connected to a power cable (206), the power cable (206) including a series of two or more cable segments, each cable segment being connected to a reel (204) of one cable reeler to a connector connected to an adjacent cable reeler, each cable reeler having a controllable motorized cable reel (216, 218), the method including supplying power to the mining equipment (102) via the cable (206), moving the mining equipment (012) along the workface; and reeling in the deployed cable (206) at a rate which approximates the speed of movement of the mining equipment (102) along the workface. Also disclosed are connectors between cable connector sections adapted to rotate relative to their mating contacts in a second connector section.
Abstract:
According to the invention there is provided a winding device (10) suitable for winding a flexible elongate member (20) thereon, comprising handle means (30), having a top end (31) and a bottom end (32), and which is adapted to be held between the posterior side of a user's arm (40) and the users hand (50); and a pair of winding formations around which the flexible elongate member (20) may be wound, preferably in the form of a pair of hook formations (60) attached to the handle means (30) towards the top end (31) and the bottom end (32). The handle means (30) comprises an operationally vertical elongate member (33) having a plurality of handle members (34) extending from it in a substantially transverse direction. The handle members (34) are disposed along the elongate member (33) so that in use a bottom handle member (34a) will be located adjacent the user's elbow (45), while a top handle member (34b) will be located away from the bottom handle member (34a) so as to coincide with the positioning of the user's hand (50). It is envisaged that the handle means (30) may include a plurality of top handle members (34b) which are spaced apart from each other to allow for variances in the length of user's arms. Alternately or concurrently, the handle means may include a plurality of bottom handle members (34a) in order to fulfil the same function.
Abstract:
A cased hose reel comprising a drum (3) for carrying hose (2) and a casing (1) within which the drum (3) is mounted. The casing (1) of the reel comprises a hose viewing portion through which hose (2) may be viewed as the hose (2) is wound onto the drum (3). The hose viewing portion is distinct from a hose outlet window (14) which provides a path through the (casing (1) for hose (2).
Abstract:
An apparatus for determining cardiac performance in the patient involving a conductance catheter (12) for measuring conductance and blood volume in a heart chamber of the patient. The apparatus includes a processor (14) for determining instantaneous volume of the ventricle by applying a non-linear relationship between the measured conductance and the volume of blood in the heart chamber to identify mechanical strength of the chamber. The processor (14) is in communication with the conductance catheter (12).
Abstract:
A reel (20) comprises a drum assembly (22) enclosed within a shell comprising upper and lower shell portions (24, 26). The drum assembly (22) is secured to the lower shell portion (26). The drum assembly (22) comprises a motor-driven rotating drum (36) secured between two discs (38, 40), and a frame subassembly (23). The drum (36) is adapted to receive linear material (150) spooled thereon. An outer surface of one of the discs has a spiral groove (88), with a first end (90) near the center of the disc and a second end (92) near an outer edge. The second end (92) is tapered to lesser depth. The frame subassembly (23) includes a track assembly (54) facing the disc with the spiral groove (88) and a translating plate (70) adapted to translate horizontally within the track assembly. As the drum and discs rotate, horizontal pins (76, 78) of the plate (70) alternatingly engage the spiral groove (88), causing the translating plate to translate linearly within the track assembly. The translating plate is connected to and causes the upper shell portion to reciprocatingly rotate about a vertical axis with respect to the lower shell portion and drum assembly. A guide aperture (128) is provided in the upper shell portion, through which linear material (150) is drawn onto the rotating drum (36). Advantageously, the aperture translates through an arc in front of the drum (36), so that the linear material (150) is distributed across the drum surface as it is wound.
