Granted: 1998-07-14
Abstract: The locking arrangement consists of key a and lock cylinder with a guide cross section provided on the rear of the key shank and with profiled longitudinal ribs arranged on the broad face for entry into associated grooves of the lock cylinder key channel.  Transversely to the profiled longitudinal ribs, there are provided wards which issue from one narrow edge of the key shank and, in their depth, follow the unit or multiple of the step jump (x) of the lock cylinder core pins.  At least the lower rib flank facing the narrow edge of the key shank is perpendicular to the longitudinal centre plane of the key shank and the distance of the lower rib flanks from one another is equal.  The lower rib flanks are arranged at a distance from one another corresponding to the unit or integral multiple of the step jump (x) and in such a way that the deepest points of the wards are at the level of the lower rib flanks which externally pass tangentially into convexly shaped curved end faces which run tangentially into the upper rib flanks.

Abstract: In a separable bottom end stop assembly for a concealed slide fastener, a socket member has first-and second-plug-member insertion holes on opposite sides of a central catch plate, and an engaging tongue projecting inwardly from one side wall. When a first plug member is inserted into the socket mem-ber, a locking portion on one side of a lower end of the first plug member comes into locking engagement with the catch plate and an engaging portion on the other side of the lower end of the first plug member comes into engagement with the engaing tongue.          With continued inserting of the first plug member, an inwardly directed hook-shape end of an engaging projection extending from an upper end of the socket member comes into engagement with an engaging recess in a rear wall of a slider. In this state, a second plug member is inserted into the second-plug-member insertion hole, and a slider is then pulled so as to move the socket member in a predetermined range, whereupon only the slider is pulled to join the opposed stringers together. To separate the closed stringers, the slider is pulled to push the socket member down, and then the second plug member is removed from the socket member and the slider.

Abstract: Hitch ball assemblies for implement hitches are welded directly into holes formed in sidewalls of tubing ends which have been flattened to provide direct load transfer from the tubing to the implement frame.  Several different flattened end cross-sectional configurations provide strong ball joint areas with a pleasing appearance.  In one embodiment, an additional plate is supported between the sidewalls prior to flattening, and the hole is formed in the two sidewalls and the plate in the same hole-forming operation.  The reduced number of hitch parts and welding steps decreases cost and dimensional variations.

Title: Packet switching system for forwarding packets from input buffers using idle/busy status of output buffers
Inventor: FAN RUIXUE
IPC: H04L47/6275
Filed: 1993-12-29
Granted: 1999-07-20
Abstract: A packet switching system comprises input buffers and output buffers, and a self-routing network for routing packets from the input buffers to the output buffers according to the routing information contained in their header. An input controller, associated with each input buffer, includes an idle/busy memory. An output controller, associated with each output buffer, detects the idle space of the associated output buffer and determines if the idle space is greater than a predetermined value. If the idle space is determined to be greater than the predetermined value, an idle status bit is generated and if the idle space is determined to be smaller than the predetermined value, a busy status bit is generated. The idle and busy status bits are broadcast to the idle/busy memory of all input controllers. Each input controller writes an incoming packet into the associated input buffer and reads it onto the self-routing network if an idle status bit is stored in the idle/busy memory corresponding to the routing information of the incoming packet.

Abstract: A digital cellular communication system provides an asymmetric speech coder for improving audio quality in the uplink channel. A high rate speech coder is provided in the uplink of the digital cellular communications system to improve the audio quality. To compensate for the higher band width consumed by this high rate speech coder, the uplink uses a channel code, such as a convolutional code, thatgenerates fewer symbols per each input bit, thereby consuming less bandwidth. The loss of coding gain as a result of the change in the convolutional code is compensated for by applying a special power control strategy. The power control strategy increases the transmit power for transceivers using the asymmetric speech coder.
