Title: Ink drop printing system
IPC: B41J2/075
Filed: 1973-10-29
Abstract: 1435618 Ink drop printers DICK CO AB 29 Oct 1973 [13 Dec 1972] 50142/73 Heading G4H An ink-drop printer incorporates means for charging the drops by ionic bombardment. The drops 20, 22 . . . are produced by a vibrating nozzle 10 and directed past a photo-cell 46 (which produces a pulse for each passing drop) to deflecting plates 90, 92 one of which contains apertures 50-58 through which ions from a source 60 can be selectively passed. The passage of ions is controlled by conductive layers 82 around the apertures and separated from plate 92 by an insulator; the layers are controlled by the outputs from shift registers 72-80. Video signals 86 are converted at 84 into charge signals for each drop; each signal is converted at 85 into a 5-bit signal and applied to the registers. If, for example, a drop is to acquire 3 units of charge then the signal is 11100, the bits being entered into the 1st, 2nd . . . stages of the registers respectively. The pulses from 46 are delayed to allow the drops to arrive at the apertures and used to shift the registers: in the present example, the sequential "1" outputs from 72, 74 and 76 apply voltages to layers 82 so that they pass ions to the drop as it passes over apertures 50, 52 and 54. The drop is thus bombarded three times by ions from 60. For printing characters, the pulses are also passed to a counter 88 whose output controls the release of the appropriate number of signals from video source 86 to control source 84. The counter may be omitted when curves instead of characters are to be printed. In an alternative embodiment (Fig. 3, not shown) only one aperture is used, the conductive layer 82 then receiving a variable voltage direct from source 84.

Filed: 1968-11-11
Abstract: 1283927 Switching systems JOSEPH LUCAS (INDUSTRIES) Ltd 29 Oct 1969 [11 Nov 1968] 53232/68 Heading H2H In an electrical system for a road vehicle, a plurality of loads are controlled by respective switches. The closure of a switch causes the energization of two or more feed lines associated with that particular switch, and results in power being supplied to the respective load. In the system shown, loads L1-L5 are each connected in series with contacts C1-C5 to a battery supply line 12. The contacts are controlled by relay coils R1-R5, and are associated with main switches S1-S5 serially connected with a relay coil 15 which is normally energized to hold open a contact 14. In operation, one of the main switches, say S1, is moved to make contact with a pair of diodes connected to two feed lines, in this case 21 and 22. The coil 15 is thus de-energized, contact 14 closes, and current flows into resistors 41-45 in series with the coils R1-R5. Each resistor is also connected through a pair of parallel diodes and resistors 31-36 to earth, and in the ease of resistors 42-45, sufficient current flows to earth to prevent energization of the relay coils R2-R5. However, both diodes associated with resistor 41 are back-biased due to the connection of feed lines 21, 22 to the battery, so that the current in the resistor 41 flows wholly through the coil R1, closes contact C1 and energizes the load L1. The relays are of the type which remain operative until re-energized, when their contacts open again. The system shown includes six feed lines 21-26 so that up to fifteen loads can be controlled by choosing all possible combinations of pairs of lines.

Abstract: 1,126,589. Decorative sheet. FARBWERKE HOECHST A.G. 16 Dec., 1965 [19 Dec., 1964], No. 53474/65. Heading B6G. Decorative sheets of plastics material for exterior cladding and wall and ceiling panelling are provided with a regular arrangement of grooves so formed that at each crossing point of the grooves at least one of four grooves at the crossing point is shallower than the remaining grooves at the same crossing point. The grooves may form a network of rectangles on the sheet surface with deep and shallow grooves alternating regularly in the longitudinal and transverse directions e.g. a deep groove extending over three rectangular units followed by a shallow groove extending over one rectangular unit. The depth of the grooves may vary over each rectangular unit so that at each crossing point a shallow groove crosses a deep groove. Materials for the sheets may be glass-fibre reinforced polyester resins, other thermosetting plastics, thermoplastic materials such as polymethacrylates, rigid polyvinyl chloride free from plasticizer, and preferably modified by the addition of chlorinated polyolefines. The sheets may be in the form of endless strips. The sheets may be fixed with a fixing means, e.g. a screw disposed at the lowest part of the grooves. When neighbouring sheets overlap, the edge of the upper sheet may lie in a groove of the underneath sheet. In Figs. 1, 1a, 1b (not shown), the underside of a sheet is provided with longitudinal grooves 1 and transverse grooves 2 on sheet surface 3. The depth of grooves 1 and 2 increases and decreases alternately from crossing point to crossing point as shown at 1a, 1b 2a, 2b. At each meeting point of four grooves two deep grooves extending in one direction meet at right angles two shallow grooves extending in the other direction. Figs. 2 and 3 (not shown), illustrate similar groove arrangements to that shown in Fig. 1, with wider grooves.

A bridge rectifier for supplying D.C. to an inductive load, e.g. a motor, from an A.C. supply at terminals A and B, is operated in the following sequence: first rectifiers 1 and 4 are fired, then at the zero crossing of the input A.C. rectifier 3 is fired so that the inductive current in the load flows through rectifiers 3 and 4 in series; subsequently rectifier 2 is fired so that the load is supplied through rectifiers 2 and 3 and at the next zero crossing rectifier 1 is fired to pass the inductive load current. This improves the power factor and ripple voltage, but if desired the firing pulses at the zero crossings may be suppressed thereby allowing the bridge to operate in a known manner with the inductive current fed back into the A.C. supply. A similar system may be applied to a three phase bridge (Figs. 4 and 6, not shown). The rectifiers may be thyristors, transistors, mercury-arc rectifiers, or series combinations of switches and diode rectifiers.
