Title: Information Storage and Retrieval Apparatus
Inventor: SIMMONDS DAVID THOMAS
IPC: G06K21/00
Filed: 1967-03-30
Abstract: 1,185,658. Information retrieval systems. NATIONAL RESEARCH DEVELOPMENT CORP. 1 July, 1968 [30 March, 1967], No. 14538/67. Heading G4M. Each cell 27 of an array corresponds to a unique combination of features, and the existence of an item possessing that combination of features is represented by recording a binary digit in the cell, selectors being used in selected combinations to select a group of cells or a single cell associated with corresponding combinations of features. The array of cells may be a sheet divided as shown, the existence of an item having a particular combination of features being recorded by punching a hole in the appropriate cell, but the use of electroluminescent or magnetic core cells is also mentioned. In the embodiment shown, a 16 x 16 matrix of cells is divided into 4x4 sub-matrices, each of which is divided into 4x4 cells, the cells and sub-matrices being numbered as shown. Each cell is specified by two decimal numbers, e.g. the shaded cell is represented by 3, 0, and the binary equivalent of these numbers, i.e. 0011, 0000 indicates the particular combination of presence and absence of 8 features which is associated with that cell. A hole is thus punched in the cell 3, 0 if an item exists having features 3 and 4 (numbering from left to right) but none of the others. Each pair of adjacent cells correspond to combinations which only differ by one feature, so that by using selector masks corresponding to the presence or absence of a limited number of particular features, certain areas can be blanked off, leaving open to view only those cells corresponding to the selected feature combination, whereby not only can the presence or absence of items with the selected feature combination be determined, but also the positions of cells which indicate the presence of an item enable other features possessed by these items to be determined. As an example, masks corresponding to the presence of features 7 and 8 blank off the top and left-hand halves of the array leaving only the sub-matrices 15, 7, 11, 3, i.e. those with a binary equivalent of 1111, 0111, 1011, 0011. Selection within a sub-matrix is performed by similar, more finely divided masks. The array illustrated may itself form a submatrix of a larger, e.g. 256 x 256 array. The system may be used in co-operation with an auxiliary card index in which cards are filed in numerical order of cell designation; each card (or cards if more than one item has the same set of features) being provided with details concerning the associated item (or items), e.g. name and address of employee.

Title: Interrogator/transponder systems
IPC: G01S13/78
Filed: 1975-03-21
Abstract: 1507050 Road-traffic signalling-apparatus PLESSEY CO Ltd 21 March 1975 [2 April 1974] 14625/75 Heading G4Q [Also in Division H4] In an interrogator-responder system for vehicle detection and traffic signal control, a signal radiated from an interrogator serial 6 in or by a roadway, traffic lane &c. is used to operate a vehicle borne transponder transmitter 2 which thereafter radiates predetermined coded data signals. The interrogator includes a receiving aerial 7 having operatively associated with it a code recognition unit 13 responsive only to predetermined coded data signals indentifying particular vehicles, this unit being coupled to traffic signal control arrangements, e.g. at 14, 15, 16. The interrogator also includes vehicle detector arrangements 8 responsive to signal changes resultant upon the passage of any vehicle over or by the receiving aerial and arrangements coupled (at 11) to register such passage. The predetermined coded data signals are radiated from the vehicle transponder at a frequency derived from the frequency of the signal radiated from the interrogator aerial. The traffic signal control arrangements may be traffic lights which clear a route for buses, fire engines &c. The coded signals in the described embodiment are phase modulated on to a carrier at half the frequency of the transmitted interrogator signals and are detected by a demodulator 8, which receives the transmitted signal via a frequency divider 9, as reference. The detector responds to slow phase variation to provide an output at 11 indicating vehicle passage, and to rapid variation to provide the actual vehicle code on line 12. In the vehicle transponder (Fig. 2) the received signal is detected by a receiver loop and passes via an interface unit 18 to provide pulses at frequency f each of which actuates a counter 19 (supplied from a battery 40). Pulses at frequencies f/ 2 ,f/ 32 ,f/ 64 ,f/ 128  are taken from the counter and applied to a logic circuit 29 which produces bursts of pulses at frequency f/ 2  in code combinations determined by the other counter outputs. These bursts are transmitted via amplifier 35 and transmitter loop 3. If the vehicle is stationary over an interrogator loop, a reset logic system 41, 42 is activated by the repeated reception of interrogator signals to reset the counter.

Title: Web handling apparatus
IPC: G03B1/56
Filed: 1971-05-13
Abstract: 1315791 Feeding webs EASTMAN KODAK CO 13 May 1971 [19 May 1970] 14691/71 Heading B8R [Also in Division G2] In one apparatus the size of loops 12, 13 are each controlled by devices 14 which pneumatically sense the size of the loop and adjusts the film feed rate by varying the diameter of a drive roller 21 to bring the loop back to a predetermined size. As shown in Fig. 1 the loops 12, 13 may be located on either side of film gate 11 fitted with claw mechanism 10. Each device 14 includes a roller 21 fitted on a driven shaft 23 which by means of belt 42 and pulley 40 powers a drive roller 44. The size of the loop is detected by a nozzle 52 connected to bellows 36 supplied with compressed air from a main 53. The variation in the distance between the film 50 and nozzle 52 (due to variations in loop size) causes the air pressure in the bellows Pb to vary between the mains pressure Ps and ambient pressure Pa. As the drive shaft 23 and bellows 36 are attached to each other, pressure variations in the bellows apply a tensile or compressive axial force to the roller 21 which is attached to plate 22. The roller 21 is preferably made of elastomeric material and the applied axial force causes a change in the diameter of the roller 21. As the roller is rotated at a constant rate a variation in the film speed results and hence the loop returns to a predetermined size.

Abstract: 626,795. Weighing-apparatus. ENTHOVEN & SONS, Ltd., H. J., and PARSONS, W. H. M. June 4, 1947, No. 14763. [Class 143] [Also in Group XXII] An automatic apparatus for effecting intermittent delivery of flowable material from a bulk supply has a pair of tiltable vessels arranged so that when one is being charged the other is held in a discharging position and when the first vessel is tilted by the weight of material therein it discharges into the other vessel which has been simultaneously tilted back into a charging position in which it remains until it has received the charge from the first vessel and is tilted into its discharging position whereupon the first vessel is tilted back into its charging position and the cycle is repeated. Vessels 1, 2 which are mounted on trunnions 3, 4 respectively in a casing 7, having access doors 8, 9, are arranged so that a pipe 5 continuously delivers liquid to the chamber 1. A pair of adjustable links 6, which are pivotally attached to the vessels, are so arranged that when the vessel 1 has received sufficient liquid to overbalance adjustable counter weights 11, 12 the vessels pivot from their chain dotted position to their full line position whereupon vessel 1 discharges into vessel 2. This continues until the weight of material in vessel 1 is insufficient to counterbalance vessel 2 whereupon the vessels return to their chain dotted position and are ready to repeat the cycle of operations. The apparatus which may be mounted to travel along a row of moulds may be traversed by a motor the actuation of which is controlled by an arm 21 secured to a rock shaft 20 which is rocked by the engagement of the vessel 2 with a U-shaped member 19. A plate 13 in the vessel 2 has slots 14, 15 and serves to prevent liquid surges. When the apparatus is used to deliver molten metal to moulds a series of gas burners 30, fed by a pipe 18, are provided to maintain the temperature of the metal and also to prevent the formation of dross.
