Abstract: Improvements in a safety belt retractor having a locking pawl and a first ratchet engageable by the locking pawl for locking a belt storage reel against unwinding movement and an actuating pawl associated with means responsive to an emergency condition. The improvements include an intermediate actuating member movably mounted between the locking pawl and the actuating pawl resiliently engaging the locking pawl and adapted to cause the locking pawl to engage the first ratchet to lock the reel when the actuating member is actuated upon an emergency condition.

Abstract: A device for regulating the operation of the transmission of a motor vehicle having a variator including a distributor which is influenced by a centrifugal regulator and/or resilient means which may be additionally controlled by an accelerator, for supplying pressure fluid from a source to a cylinder chamber or for connecting the chamber to a reservoir, a piston movable in said cylinder chamber being connected to a step-down control element of the variator. As a safety device to prevent imbalance in the event of a failure of the centrifugal regulator, a two-piston electrically operated valve is incorporated between said source and said chamber, the valve being controlled by an electrical circuit arranged to close the valve and prevent the flow of pressure fluid from the source to the chamber if the speed of the engine exceeds a predetermined value. If desired, the valve may serve to control flow of pressure fluid to and from a hydraulic brake for the input shaft of the variator.

Two parallel normally open arms of the energizing circuit of the valve may be closed by two switches respectively operated by a member connected to the accelerator of the vehicle and by a member connected to the reversing gear, energization of the electrically operated valve leading to an interruption of the discharge conduit of the device.

Abstract: A portable device for cutting and removing nuts, has two hydraulic assemblies connected by a high pressure, flexible hydraulic line. At one end of the line is a light hand-powered hydraulic pump, effective at any orientation. Attached to the other end of the line is a compact hydraulically actuated head unit. Recessed into the unit is a curved moveable jaw, opposite which and also recessed is a cutting blade. Enough room is provided between the cutting blade and the jaw for a nut to fit snugly. Pressure from the pump drives the piston towards the cutting blade, and cuts the nut, permitting its easy removal.

Abstract: A frame has channel members extending along each edge of the frame material with each channel member abutting another member at the corner of the framed material. A locking member is slidable between the frame material and the pairs of abutting channel members at each corner of the frame material to hold the channel members together against the frame material. The channel members may have slots therein and the locking members may have protrusions to extend into the slots when the locking member is inserted between the frame material and the channel members. The frame material includes a transparent sheet for displaying an object therethrough and a rigid backing sheet on the other side of the object, and the channel members have a channel width substantially the same as the combined thickness of the transparent sheet, the object, the rigid backing sheet and the locking member.

Abstract: A support for supporting a golf bag in a position on a supporting surface wherein the golf bag is at an angle of less than 90.degree. with respect to the supporting surface. The support is removably secured on the golf bag. When not being used, the support lays flat against an upright golf bag. When it is desired to use such support, the golf bag is lowered by pivoting the bottom end of the bag on the supporting surface, the support at the upper end of the bag swinging under gravity outwardly away from the golf bag and, in outer position, supports the golf bag on a supporting surface in inclined positin without the necessity of manually locking the support in position. When it is desired to release such support, it moves under gravity back into position against the golf bag as the bag is raised without the necessity of manually releasing the support.

Abstract: A bi-directional digital communication unit for requesting the performance of services by transmitting data to a central computer complex for purposes of processing the data to utilize it to initiate the performance of the requested services and for receiving data from the central computer complex for purposes of determining whether the request for the performed services was received and the performance of the requested services was initiated. Data is transmitted from the central computer to the communication unit on a carrier wave at a first low frequency F.sub.1 and data is transmitted from the communication unit to the central computer at a second low frequency F.sub.2. The data received by the system, on the carrier wave having frequency F.sub.1, is demodulated and applied to valid address check means to determine if the central computer has transmitted a valid address to the unit.

Abstract: Disclosed are a composition produced from rubber containing polymeric hydrocarbons and carbon black by pyrolyzing and grinding such rubber with heated balls for a sufficient length of time to vaporize and depolymerize the hydrocarbons and to produce a solid char material having a very fine particle size, said char material being free of nondecomposed rubber and coke and having a benzene discoloration number of greater than 70% and preferably 90%, and the related method of making the composition. If the rubber also contains fiberglass and metal, the solid material produced in the pyrolyzing and grinding step will contain fiberglass and metal. The fiberglass and metal are separated from the solid char particles by mechanical means using no caustic, acid or organic solvents. The resulting char may be used, among other things, as a substitute for carbon black in the production of various products such as tires.
