Title: Electrical plugboard assembly and plugs therefor
IPC: H01R24/52
Filed: 1965-08-13
Abstract: 1,087,430. Plugboards; two-part couplings. AMP Inc. Aug. 13, 1965 [Aug. 25, 1964], No. 34808/65. Heading H2E. A plugboard assembly comprises a front board 102, into which interconnected shielded contact members 141 are selectively plugged, a rear board having an array of shielded contact members 121, and a mechanism which moves the front board close to the rear board so that the two sets of contacts overlap and then moves it parallel to the rear board firstly in a direction to engage co-operating contacts and secondly slightly in the opposite direction so that a wiping action takes place but the contacts remain in engagement. The front board has hooks 112 and handles 106, 110 by which it is supported on a scissors linkage 40, 42 and 80, 82 which is closed by operating a handle 70 on a shaft 26. During this action the links 42, 82 are initially locked to the shaft 26 by latches 89, Fig. 6 (not shown), but when the linkage is closed, further rotation of the shaft 26 disengages the latches and eccentrics 72 act through arms 74, on which the links 40, 80 are pivoted, to lift, and then slightly drop, those links and the front board which is carried by them. A bar 22 on the rear board engages a grooved bar 107a on the front board to align it laterally This function is also performed by nylon projections 84 on the links 40, 80, and further projectons 41 on those links enter slots in the brackets 108 of the front board handles so as to locate that board vertically in relation to the links. Finally, rear extensions of the projections 84 engage behind locking members 15 to hold the linkage closed. Each rear board contact member is in two parts which mate with each other. One part 122, Fig. 9 (not shown), has an outer conductor 122a, 122d connected by a crimping ferrule 128 to the outer conductor of a coaxial cable, and a pin 127a within an insulating sleeve and crimped, through holes 122b in the outer conductor to the core of the cable. The other part 124 has a socket to receive the outer conductor 122d of the first part and a shield portion 124h which is cut-away at its lower section to allow the mating contact to engage laterally with the inner contact 126. The latter is forked, has a socket to receive the pin 127a of the first part and is mounted in an insulating sleeve 125 inside the part 124, which is retained in the board by spring fingers 124b and has a V-section portion to ensure its correct orientation in the board. Each front board contact member has one part 144, Fig. 10 (not shown), with coaxial conductors 144a, 149 crimped to the corresponding conductors of a coaxial cable. The inner conductor 149 is a pin which engages between the prongs of the inner contact 126 of the rear board contact member. A second part 142 fits over a plated contact ring 145 of the first part in such a way as to allow some relative movement and has sharp-edged bars 142c which bite into the board to hold the member in place. This part 142 acts as a shield but is open to one side to allow the lateral mating movement.

Title: Associative Memory
IPC: G11C15/02
Filed: 1967-07-28
Abstract: 1,158,828. Associative memories. INTERNATIONAL STANDARD ELECTRIC CORP. 28 July, 1967 [3 Aug., 1966], No. 34814/67. Heading G4C. In an associative matrix memory using magnetic cores which are read destructively, the interrogation takes place column by column, row sense circuits are set during interrogation from a first to a second of three states if any sense pulse indicating mismatch is received on the corresponding row and, after interrogation, the row sense circuits operate in chain fashion to control the sequential read-out of all rows in which a matching word was found, all row sense circuits during this last process being sequentially set to the third state. A row sense circuit comprising two flip-flops A and B is shown in Fig. 3. At the start of a memory search operation each pair of flip-flops is reset (initial state X 1  = #A.#B). If a sense pulse is received during interrogation on a row wire LV the corresponding flip-flops are initially set to state X 3  = A.B (the row wire N being then marked for rewriting of binary information) and after rewriting has been effected the flip-flops are set to state X 2  = #A.#B. by a pulse T6. Thus after all columns have been interrogated, the row circuits are in a state X 1  = #A.#B indicating a match or X 2  = #A.#B indicating a mismatch. A pulse is now applied at input Y K  of the first row circuit (top row in Fig. 1, not shown), and depending on the state of that circuit either flip-flop A is merely set thus changing the row circuit to said third state X 3  = A.B and a pulse generated at outlet Y K+1  for use in the next circuit or (in the case of matching rows) a signal is generated on line M for causing the corresponding row to be read-out and binary information to be rewritten and the row circuit changes in sequence to state X 2  and then X 3 . Successive pulses applied to the same input Y K  therefore cause all matching rows to be read-out in succession. Finally all row circuits are returned to the state X 1  = A B.

Title: Improvements in processes of recovering neutral grease from wool washing water
IPC: C11B11/00
Filed: 1930-11-19
Abstract: Neutral wool grease is recovered from wool-washing waters which have been concentrated, by treating the concentrate in a digester in which the temperature and pressure are controlled independently.  The concentrates, produced for example by agitation with air, or by precipitation agents such as lime, calcium chloride, sulphuric acid or clay, are heated by steam in a digester at 90 DEG -100 DEG  C., and a gas such as air or oxygen is forced in, whereby water, and impurities such as soaps and albuminoids p  are separated. Preferably the gas is injected before the temperature reaches its maximum value, whereby combination between the grease and impurities is prevented.  In a modification, the concentrate is heated below the maximum temperature before treatment in the digester.  Specification 273,642, [Class 91, Oils, &c.], is referred to.

Abstract: 1436004 Production of integrated circuit memory arrays CENTRE DE RECHERCHE INDUSTRIELLE DU QUEBEC 27 July 1973 [28 July 1972] 35999/73 Heading G4A [Also in Division H1] An integrated circuit, e.g. a read only or random access memory, is produced by forming a plurality of identical circuit arrays on a substrate, each array having a section which may be programmed to respond to a given set of electric input signals (e.g. an address) and each being connected to a common set of input lines, for successive ones of the arrays, programming the programmable section to respond to a predetermined set of electric signals and testing the array, the set of signals to which each array responds being the same as for the preceding array if that array was bad and being different from all other previously used sets if the preceding array was good, and breaking the connections between the common input lines and each band array. The programmable section of each array may consist of a number of exclusive-OR gates each having one input connected to a respective address-bit input line and a second input connected to zero and one logic level via respective fusible links. A fusible link is blown for each gate so that a fixed input pattern is presented to the gates for comparison with the address inputs. The gates feed a NOR gate which supplies an array select output signal. Various other different logic networks, including exclusive-OR gates and a NAND gate, are mentioned. The resulting circuit is mounted on a standard integrated circuit package and connections are established to the common lines which in the case of a memory include address lines for array selection and cell selection within an array, and data, strobe &c. lines.
