Title: Wheel slip control system for automotive vehicles and the like
IPC: B60T8/172
Filed: 1973-03-07
Abstract: 1393841 Antiskid braking systems WAGNER ELECTRIC CORP 7 March 1973 [10 March 1972] 10964/73 Heading F2F [Also in Division G3]  In a vehicle wheel braking system, the brake pressure is relieved when a limiting deceleration is exceeded and not reapplied until a preset acceleration is achieved. As shown (Fig. 1), the angular velocity of two wheels are measured at 10, 16 and fed to a selector 22 which passes the lower signal v(t) to a differentiator 30 producing a rate of change signal a(t). The deceleration signal produced when the brakes are applied is compared at 32 with a reference value to pass on a pulse to OR gate 34, when the reference value is exceeded, and open gate 36, allowing the velocity signal v(t) to be fed to a unit 38, where the reducing v(t) signal is subsracted from v 1 , the initial v(t) signal reaching unit 38, and the difference v 1 -v(t) is compared with a variable reference signal #v from unit 40, which is inversely proportional to a(t). When the reference signal #v is the greater of the two inputs, a pulse is sent from conparator 38 to OR gate 42, to energize solenoid 46 and relieve the brake pressure. The deceleration signal a(t) then decreases until the output from circuit 32 is terminated, the gating elements 34, 36, 42 are closed after a delay determined by a timer 50, braking pressure is reapplied and the process is restarted. The timer 50 also inhibits the reapplication of braking pressure until the acceleration of the sensed wheel exceeds a reference value fed to comparator 54, in order to cope with wheel lock conditions produced by a road surface having a low coefficient of friction.

Patent GB-1422243-A (GB)
Title: System for searching messages in a memory
IPC: G11B27/22
Filed: 1973-03-07
Abstract: 1422243 Data retrieval INTERNATIONAL STANDARD ELECTRIC CORP 7 March 1973 11072/73 Heading G4C A storage system, e.g. a magnetic tape system, includes a tape storing data in blocks separated by gaps, each block containing a plurality of messages each of which contains a series of characters of which some are message identifying (tag) characters, a means for comparing a set of desired messages identifying characters with characters read from the tape, a counter arranged, following a positive comparison, to count the number of characters subsequently read from the tape until an interblock gap is detected, and a means for stopping the tape in the detected inter-block gap whereby the message having the desired identifying characters may be located. As described characters are stored in parallel across the tape which contains blocks of 1024 characters separated by gaps, each block containing three messages MS1-MS3 each of which begins with three tag characters. A computer PR writes the address of a storage location in a predetermined location in memory M. The location referred to contains the number of tag characters to be located and the identity of the first of these characters, e.g. for message MS2 in block Bb three characters and the character CRD. The information is taken over by the tape control circuit UG which subsequently starts the tape DB. Read out from the tape passes to a comparator OPC to which the first tag character is supplied and to a detector SI which produces a signal HL2 each time a character is read and a signal GAP each time an inter-block gap is detected. During the search for comparison with the first tag character the second is obtained from memory M by incrementing the address which was used to obtain the first. Assuming block Bb is being read a positive comparison with the first tag character of MS1 will be achieved. Following the comparison counter Cn is set to 1, comparator OPC is supplied with the second tag character CRE, and the third tag character is called from memory. The second tag character of MS1 however does not yield a positive comparison and counter Cn is reset to zero and the first required tag character is supplied to comparator OPC. It will be seen that three successive successful comparisons will be achieved at the start of message MS2 with the result that counter Cn will be set to 3 and a positive comparison between Cn and the number of tag characters to be located will be achieved. Following this comparison a counter RN is incremented for each character read from the tape until a gap is detected whereupon the tape is stopped. The block (Bb) in which the required message was located is then read into memory M together with the count RN. The computer PR is thus able to locate the required message in the block.  The specification describes the searching operation in some detail with the aid of flow drawings.
