Filed: 1974-08-30
Abstract: 1478188 Display stands FITTALL PRODUCTS Ltd 22 Aug 1975 [30 Aug 1974] 38032/74 Heading A4T A display unit e.g. for cassettes 15 comprises trays 14 spaced along a support member 11 and providing between them at least one display section the trays 14 being rotatably supported and relatively movable axially to allow removal of the cassettes 15 by relative rotation on the support member 11. The cassettes 15 are supported on flanged spokes 38, Fig. 3 of the trays 14, with lugs 41 projecting from rims 40 to prevent removal. The trays 14 are spaced apart by spacer sections 17, locked for rotation with upper limb sections 16a of the trays, while lower hub sections 16b are formed with cam tracks 19, which co-operate with tracks 18 on the adjacent spacer section 17 to convert relative rotation between trays 14 into axial movement. The overall height of the trays 14 is defined by fixed end washers (11a, 33) Fig. I (not shown), on the member 11, and an advertising section 22 is preferably provided at the top of the unit, comprising an advertising surface 35 fixed between two trays 14. In use of the unit, a locking section 21, located between two appropriate trays 14 with a shortened spacer section 23 is actuated so that a spigot 26 locks said two trays together. The spigot 26 passes through the spacer 23 and hub 16b with the tracks 18, 19 holding the trays 14 at maximum separation so that the washers (11a, 33) prevent any of the trays from being pushed apart. To release a cassette, the spigot 26 is unlocked, and the trays 14 adjacent the locking section are relatively rotated, the tracks 18, 19 co-operating so that these trays 14 move together, the tray or trays 14 above also dropping to shorten the overall height. The trays 14 between which the required cassette 15 is located may then be relatively rotated to increase their spacing, the cam tracks 18, 19 causing the upper tray 14 to rise, along with any trays 14 above, to an extent limited by the washer (33) so that the cassette 15 may be removed.

Title: Improvements in the combustion chambers of internal combustion engines
IPC: F02M69/00
Filed: 1929-12-13
Abstract: 345,254. Combustion chambers for direct-injection engines. DODSON, E., 66, Lewin Road. Streatham, London. Dec. 13, 1929, No. 38250. [Class 7 (iii).] In an engine in which a pre-combustion chamber C is connected to the main combustion chamber B by a venturi passage E, into which liquid fuel, or a rich mixture, is injected through a series of orifices F, turbulence is produced by locating the passage E on one side of the plane through the centre of the chamber C and the cylinder axis. A passage H connected to a region of higher pressure ensures that a passage G, behind the orifices F, is emptied after the injection ceases. Separate air valves are provided for each of the chambers B, C. Injection takes place, preferably as described in Specification 344,542, during the compression and expansion strokes, and it may continue after ignition of the richer mixture in the chamber C, either by sparking-plug J, or by compression-ignition. The volume of the chamber C is preferably half the total cylinder clearance.

Title: Digital Vector Generator.

Filed: 1968-08-12
Abstract: 1,197,656. Cathode-ray tube displays. SPERRY RAND CORP. 12 Aug., 1968 [15 Aug., 1967], No. 38474/68. Heading H4T. In an arrangement for generating digital signals controlling successive deflection displacements of the beam of a cathode-ray tube to trace a linear function of any slope signals producing a unit displacement are generated when the lowest order stage i of a counter of n bi-stable stages is in agreement as to state (e.g. a "1") with stage n-(i-1) of each or either of two registers of n bi-stables stages to which digital data indicative respectively of the orthogonal components (X, Y) of the function is supplied, the counter being successively incremented by one count until all n stages are in the same state (i.e. state "1"). Referring to Figs. 1 and 3, digital data indicative of incremental #X, #Y deflections are supplied by a computer or keyboard to respective registers 2, 4 and thence to individual AND gates 72, 84, 86, 88 in respective comparators 14, 16. The AND gates are then enabled by the output of the different stages of the counter 6 which, connected as shown, pass a signal from that stage of register 2 and or register 4 which is in the same state as the state of the lowest order stage of the counter 6 according to the condition set out above where n = 4. (Also Fig. 2a, not shown), the enabling of the other AND gates being inhibited by signals derived via inverter stages 1, 80, 96, 100. The output signals from the comparators are then supplied via subtractive adders 106 (a sign bit being supplied at input 120 from the computer or keyboard) to registers Xi, Yi which store digital data representative of the existing position of the beam. The output from the latter registers is then converted to analogue form in D/A converters 38, 40 and supplied to the beam deflection means. When, as a result of the comparison described above, an output signal is not produced a blanking circuit 32 is operated to blank the beam. When the binary numbers in the registers 2 and 4 and in the counter 6 are small and when, as is the case in practice, the number of stages in the registers and counter is large, the computer or keyboard is arranged to normalize such numbers by shifting the values stored in the registers one place to the left at a time and the value stored in the counter one place to the right at a time until the highest order "1" in the larger of the two numbers in the #X or #Y registers is in the highest order stage of that register (also Figs. 4a and 4b, not shown). This avoids the counter from counting through a large number of counts before the first "1" in the highest order position is encountered and the beam can move. The timing cycles employed are described with reference to Fig. 5 (not shown), and the timer itself with reference to Fig. 6 (not shown).
