Title: Electrical supply system
Inventor: WRIGHT FRANK
IPC: G08C19/34
Filed: 1970-04-10
Abstract: 1282657 Supply systems for vehicles JAGUAR CARS Ltd 19 April 1971 [10 April 1970] 17053/70 Heading H2H [Also in Division G4] A supply system for a plurality of loads comprises a single supply line and a plurality of signal lines together with a plurality of switches, each switch, when operated, energizing a unique combination of two of the signal lines so as to cause energization of the load asssociated with the switch. The system is particularly useful in a motor vehicle having a plurality of loads 18- 21 which are energizable by the battery 9 of the vehicle by way of a single power line 1 and respective relays 22-25, the relays being of the bi-stable type. A number of serially connected switches 30-33; one for each load, 18-21; are connected to the battery 9, operation of each switch energizing a different two of a number of signal lines 2-5. Thus, momentary operation of switch 30 energizes signal lines 2, 3 by way of a pair of diodes 28. Signal lines 2, 3, when energized, cause relay 22 to operate by way of a pair of diodes 27 thus closing contact 14 to energize the load 18 from the supply line 1. A second momentary operation of the switch 30 is needed to disconnect the load 18 from the line 1. The arrangement of the switches 30-33 ensures that only one is effectively operated at any one time and, by arranging that each needs only momentary operation, allows successive use of any switch. In a second embodiment double pole switches are used which obviates the use of an earth return for the relays. The signal lines may also be used for the supply leads to instruments which are commonly installed in motor vehicles.

Title: Improvements in the manufacture of cellulosic material
IPC: C08L1/00
Filed: 1932-06-16
Abstract: For the purpose of delustring or strengthening sheets, films, threads, &c. made by extrusion of cellulosic solutions, there is incorporated in such solutions a finely divided polymerization product of an aldehyde, which is insoluble in the cellulosic solution and has a refractive index different from that of the cellulosic material.  Suitable polymerization products are paraformaldehyde, trioxymethylene and metaldehyde; and it is convenient to disperse, as by grinding, the polymerization product in a liquid component of the cellulosic solution and then to add the dispersion to the latter. When a strengthening effect alone is desired, 1-5 per cent of the polymerization product based on the cellulose ester &c. suffices; but for delustring, higher proportions, say 10-15 per cent, are required, and even up to 25 per cent if a highly delustred product is desired. To the cellulosic solution there may also be added inorganic pigments to assist in the delustring and also resinous condensation products such as the condensation product of an aldehyde and a toluene sulphonamide, or a glycerinephthalate ester or a glycerine-rosin ester, these latter products having a strengthening effect, or if employed in the more highly condensed form, a delustring effect in addition.  The process is applicable to solutions of cellulose esters and ethers, for example, cellulose acetate and nitrocellulose, and to viscose and cuprammonia cellulose solutions.  Specifications 22540/96, [Class 2, Acids and salts, Organic &c.], 293,350, [Class 2 (ii), Cellulose &c.], and 359,249 are referred to.

Title: Improvements relating to feeding sheets of flexible material to machines
IPC: B65H5/02
Filed: 1945-07-05
Abstract: 583,308. Feeding sheets. CLARK, D-A. M. (Southworth Machine Co.). July 5, 1945, No. 17170. [Class 100 (i)] In a sheet-feeding machine of the kind in which a pile of sheets 12 is enveloped by a conveyer 16 having open portions 17 and relatively closed portions 18 and in which sheet pickers 52 move through the open portions 17 to raise the trailing edge of the top sheet and hold it above the conveyer until a portion 18 passes between the raised sheet and the stack and finally feeds the separated sheet to a printing or like machine, is so constructed that pickers 52 release the sheet in timed relation to the cycle of travel of the conveyer. The pickers 52 in the form of suction separators are mounted in a carriage 63 which is longitudinally adjustable on guides 66, 67 so as to enable the pickers to operate on sheets of different lengths, and the pickers are raised and lowered by a support adapted to be operated in synchronism with the movements of the conveyer. The conveyer is driven by sprockets on shafts 26, 27, 28, 29 and chains 38, 39, and the raising of the pickers is effected by a pitman 61 attached to a bar 51 in which the pickers are adjustably mounted, the pitman being actuated by a crank on a wheel 62 driven by a gearing from a sprocket in constant engagement with the conveyer chains, so that the timing of the raising and lowering of the pickers depends on the setting of the carriage 63 for sheets of different lengths. The air pressure in the pickers is controlled by a valve 74 operated by a cam 76 driven by gearing from the conveyer shaft 26; and the air pressure is controlled so that the sheets are released to the conveyer with their leading edges in substantially the same position on the conveyer for all lengths of sheets. The pile table 13 is inclined, and is supported by a bracket 85 which is raised automatically by a chain-operated by worm gearing from a ratchet mechanism controlled by a roller 15 engaging the top of the pile. The ratchet 100 -is operated by pawl 102 when the pile needs raising. This pawl is mounted on a pivoted plate 101 which tends to move clockwise in Fig. 1 owing to its centre of gravity being to the right of the shaft 98 of the ratchet wheel. The plate 101 is moved counterclockwise, Fig. 1, by a slotted link 105 actuated by a crank on the shaft of the cam 76, and this movement raises the pile table if the plate is permitted to move clockwise when free for the pawl 102 to engage a further tooth of the ratchet. 100. If the pile does not need raising the clockwise movement of the plate 101 is prevented by a stop on a lever 111 controlled by the rising and falling movement of the roller 15. The front edges of the sheets engage a gauge plate 84, and the separated sheets are controlled by lower guide 22 and upper one 50. The sections 18 of the conveyers are formed of flexible strips secured to bars 41, 42, 43, 44 which are clamped to the conveyer chains.

Abstract: 1,055,515. Electrostatically driven analogue device. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 26, 1965 [May 11, 1964], No. 17464/65. Headings H1M and H1S. [Also in Division G4] The basic feature of an electrostatically driven analogue device providing analogue or digital outputs corresponding to the amplitude and/or duration of an analogue input is a flexible conductor 14 having its opposite ends attached one to each dielectric layer 12, 13 on adjacent surfaces of electrodes 10, 11 as shown, so that a " transition " portion 15 of the conductor 14 lies between those portions thereof lying flush against the dielectric. As the area of conductor 14 in contact with one dielectric layer varies at the expense of the other, there is an apparent longitudinal motion of the transition portion. This movement may be controlled by the circuitry shown, wherein conductor 14 is connected to a potential source V<SP>+</SP>, and electrodes 10 and 11 to earth. By closing switch S2 so that electrode 11 is also at potential V<SP>+</SP> transistion portion 16 moves leftward as a greater area of conductor 14 covers electrode 12 to accommodate the charge, the rate of movement being related to the potential difference and the extent of movement to the time the switch is closed. Fig. 2 (not shown) illustrates a display device, wherein, depending on the position of the transition portion, light is reflected therefrom through the transparent electrode to illuminate one of the indicia on a display element. Fig. 3 (not shown) illustrates a document reading apparatus, wherein a light beam can reach a light sensitive element only when perforations on a punched card or recorded tape, the two stationary electrodes and the flexible conductor are aligned. Fig. 4 (not shown) illustrates an analogue memory device wherein the electrodes 10 and 11 of Fig. 1 are divided longitudinally and separated by resistance strips to which the ends of conductor 14 are also attached. Variation in the position of the transition portion is accompanied by variations in the effective resistance of the two circuits, and the output voltage levels (at 43 and 45 in Fig. 4) will vary such that their sums remain constant. Fig. 5 (not shown) illustrates a multi-level control element or counter wherein the potentials at A and B (see the Figure) depend on the position of the transition portion, and this is varied by the " add " pulses to input 54 and " subtract " pulses to 53, and the signal level across reference points 58, 59 corresponds to the algebraic sum of the pulses.
