Title: Method and System of Ensuring Integrity of Data in an Electronic Memory
Inventor: COZA GEORG V
IPC: G11C29/00
Filed: 1983-03-18
Abstract: Upon recognition that some memory cells in a memory may become defective, the initial data together with the initial address (N1) are stored at a replacement address (N1'). A register, further, stores those addresses (N1) which relate to memory cells or locations which have become defective. When a computer (1) addresses data, a comparator (9) compares the called-for address with the address stored in the defective cell register (10) and, upon equality, goutes the data request to the replacement address (N1') which may be a complete address or a specific location related to a reference address, such as a terminal portion of an auxiliary memory, the main memory, or the like. A warning signal can be given when most, but not yet all, auxiliary memory locations are occupied. <IMAGE>

Title: Filter arrangement
Inventor: LAM PING-SI
IPC: H03H17/02
Filed: 1983-08-13
Abstract: A filter arrangement, for use in a signalling system of the type which handles signals of a first and second frequency (f1,f2), is constituted by three 2nd order digital filters (B1, B2 and B3). Filter (B1) supplies filter (B2) with a signal resonant at f1 and filter (B3) with o signal having a zero at f1. From these, filter (B2) generates a filter output signal (F1) having a finite gain resonator characteristic at f1 and a zero at f2 and filter (B3) generates filter output signals (F2, F3). Signal (F2) has a finite gain resonator characteristic at f2 and a zero at f1, and signal (F3) has a zero at both f1 and f2. <IMAGE>

Title: Fifth wheel trailer coupling
Inventor: JAKOB LOTHAR
IPC: B62D53/10
Filed: 1983-09-05
Abstract: The locking hook 13 has first and second pivotal connection points 21, 25 which are arranged one on either side of the pivot 14, and the unlocking member 17, 17a is connected, or connectable, to a selected one of the first and second pivotal connection points 21, 25. This enables the unlocking member to project either to the one side, or to the opposite side of a towing vehicle on which the fifth wheel coupling is provided. Accordingly, the fifth wheel coupling can be readily adapted for use by vehicles travelling normally on the right, or left hand side of a road. In addition, preferably the pivots 2 and 14 are spaced by the same distance laterally from the longitudinal axis 8 of the vehicle, so that the positions of the coupling claw 3 and locking hook 13 can be interchanged. By virtue of interchanging of the position of the locking hook 13, this provides two further alternative positions for the unlocking member 17, 17a. <IMAGE>
