Title: Apparatus for carrying out technical processes by glow discharges
IPC: H01J37/32
Filed: 1954-05-27
Abstract: 794,175. Electric glow discharge furnaces. BERGHAUS, B. May 27, 1954 [May 28, 1953], No. 37656/57. Divided out of 794,174. Class 39(3) [Also in Group XL(a)] A glow discharge vessel for the treatment of a plurality of metal work pieces has a wall part 1 removably attached by a packing 4 to a wall part 5 of the vessel, and the removable part 1 carries lead-in insulators 6...11 and 16...19 and inside holding parts e.g. rings 12, 15, 20, 21 for the work pieces 14 or auxiliary electrodes 13 or both, the work pieces 14 e.g. metal tubes being arranged with respect to each other to the holding parts and to the inside surfaces of the vessel so that the heat radiation to be received on each work piece from other work-pieces or from the holding parts is approximately the same for all solid angles of each workpiece and the heat to be transmitted from each work-piece is also the same for all solid angles of all the work-pieces. The work-pieces 14 are suspended from leading- in insulators 7, 9, 11 either individually or if the work-pieces are in groups they are suspended by an annular support 15. The lower ends of the work-pieces 14 are supported in rings 21 attached to leading-in insulators 16-18 in the lower closing part of the removable part 3. The auxiliary wire electrodes 13 are suspended centrally in the tubes 14 from an annular support 12 connected to leading-in insulators 7, 9, 11 and are attached at their lower ends to a ring 20 attached to a leading-in insulator 19. The upper and lower groups of leading insulators are in parallel planes symmetrically with respect to the central axis of the vessel. The electrical and thermal effects caused by the lead-in insulators and supports on the work-pieces are identical. The vessel has water-cooled heat-insulated walls and the inner wall is a reflector. The insulators are screened by protective gaps and may be cooled. A multi-phase current may be used and each work-piece may be connected to one phase, the auxiliary electrodes being connected to the star point of the supply. The lower group of leading-in insulators may be supported by tubes of small diameter to the upper cover of the vessel, thereby allowing vertical adjustment for work-pieces of different length.

Title: Web splicer
IPC: G03D15/04
Filed: 1970-03-23
Abstract: 1320221 Splicing apparatus EASTMAN KODAK CO 6 Aug 1970 [11 Aug 1969] 37993/70 Heading G2C In an apparatus for splicing webs such as film strips, one of the strips is mounted on a carriage which can move through such a path that the forward edge is lowered on to the splicing station to lay the end of the film strip thereon. The arrangement is of particular use when the leading edge of the strip is curled downwards, instead of lying flat. As shown, the apparatus comprises a frame 6 having a central splicing station 8 to which a tape is fed by a mechanism 10, the two strips 20, 20' to be joined being fed from either side by carriages 40, 40'. The splicing tape 12 is placed manually, adhesive surface upwards, on the bed 30 of a reciprocating table 32 when it is drawn out to the extended position shown in broken lines, and held in position by the elongated end of a clamping lever 35. The table is then slid inwards to position the tape on surface 14 of the splicing block 8. The carriage 40, which carries the film roll holder 16, is mounted on the main frame 6 by a pair of cranks 50, the cranks being linked together by sprockets 58 and a chain 60. The forward end of the film strip 20, after being trimmed by a cutter 42, is advanced until its leading edge abuts against a fixed stop 44 on the frame 6, and is then clamped by a bar 48. In this position the film strip is over-hanging the forward edge of the carriage. By means of a knob 62 the carriage is now moved in a substantially circular anti-clockwise path, constrained therein by the cranks 50, to a final position in which the base of the carriage is resting on the top of the stop 46. In this position the leading edge of the film strip rests on a portion of the adhesive surface of the tape 12. As the carriage approaches its final position, it retracts slightly, so that if the overhanging edge of the strip is curled downwards, it is laid on the tape 12 by a wiping action which tends to flatten out the curl. The retracting movement also causes the carriage to engage and depress a spring-headed roller 64. Similarly the leading edge of film strip 20' is laid on tape 12 in alignment with strip 20. The pressing mechanism is actuated by a handle 76, which causes a shoe 68 to move downwards into engagement with strips 20 and 20', pressing them into contact with the strip 12 on the heated splicing block 8. When the splice has been completed Fig. 3, (not shown), the shoe 68 is raised, the clamps 48, 48' removed, and the carriages returned to their normal position. The spring-headed roller 64 now lifts the spliced joint off the block 8.

Title: Improvements relating to contactor starters for electric motors
IPC: H01H50/88
Filed: 1929-12-11
Abstract: 337,658. Electrical Apparatus Co., Ltd., Barbour, R. H., and Walton, J. R. Dec. 11, 1929. Master control; controllers, retarding.- One or more contactors constituting a motor control system have their closing delayed by a mechanical escapement which is directly controlled by a pendulum, the escapement being connected to the moving member of either the contactor or an auxiliary switch such as a drum controlling the circuit of the contactor. A bar h is pivoted to the contact-lever d, and has rack teeth &c. engaging a pinion l. The spindle n carries a spur wheel o meshing with a pinion q fixed to an escapement wheel r, the movement of which is controlled by an adjustable pendulum t. Closure of the contactor is initially retarded by the pendulum t until a recessed part of the bar h slides over the pinion l, the final closing movement being rapidly performed. On opening under gravity, the teeth k slide over those of the pinion l. The device is also applicable to the system described in Specification 202,509.

Title: Analogue display devices
IPC: G01R13/40
Filed: 1972-08-19
Abstract: 1388933 Digital control of displays SOLARTRON ELECTRONIC GROUP Ltd 20 Aug 1973 [19 Aug 1972] 38780/72 Heading G4H A display comprises a linear array of M adjacent groups of N photo-electric devices each having first and second electrodes E, F, the rth input E of each odd-numbered group and the (N + 1-r)th input E of each even-numbered group being connected to a respective one of N coplanar conductors C, none of which crosses another, and all the inputs F of a group being connected to a respective one of M coplanar conductors D. The devices may be liquid crystals (as described with reference to Fig. 2), or light-emitting diodes 1D2, &c., and provide a display in the form of a strip whose length indicates the quantized analog value of a digital measurement. The circuit of Fig. 3 may be used to control ten groups of liquid crystal segments having "tens" and "units" electrodes D1-D10, C1-C10. The digital measurement (e.g. the value 84), passes to stores 43, 44. Digit 8 in store 43 is compared at 47 with the output from a ring counter 50 which repeatedly counts from 11 to 1, a signal 54 being produced on a count of 9 which sets a flip-flop 56 whose output enables gates H1-H10 and, on the next pulse from a clock 52, sets a flip-flop 84 to enable gates J1-J10. Digit 4 in store 44 is decoded at 68 to produce a signal K5 which passes to FETs 71 in a ladder 70 which enable gates J1-J5 and hence gates H1-H5. Thus electrodes C1-C5 are selected as counter 50 is selecting electrode D9: the result is that a strip corresponding to values 80-84 is rendered visible. On subsequent counts of counter 50, gates J1-J10 and H1-H10 are enabled by flip-flop 84 so that electrodes C1-C10 are all selected while D8-D1 are being selected in turn: thus, owing to persistence of vision, the final result is a visible strip extending from 0 to 84. Owing to the way in which alternate groups are interconnected (Fig. 2), a device 77 controlled by a flip-flop 75 is effective to transmit the complement of the digit in 44 on alternate clock pulses. Thus if the value had been 74 instead of 84, signal 54 would have been produced when the decoder input was 5, the output then being K6. Flip-flop 75 also selects FETs 72 in ladder 70 instead of FETs 71, and these provide outputs which enable gates J6-J10 instead of J1-J5 as before. The subsequent energization of electrodes C1-C10 by flip-flop 84 may be omitted if only a position indicating display is required. The display line may be curved and can be used in a digital clock, two lines arranged circumferentially at different radii then indicating minutes and hours. The length of the line may be logarithmically related to the value being indicated.

Title: Device for automatically controlling a gaseous or liquid fuel fired appliance
IPC: G05B11/16
Filed: 1975-09-24
Abstract: 1505710 Burner control system BICOSA SOC DE RECHERCHES 24 Sept 1975 [4 Oct 1974] 39118/75 Heading F4T A gas or liquid fuel fired appliance comprises a fuel supply valve (11) aotuable by a reversible electric motor (10), a first electric circuit, Fig. 1 (not shown), supplying current to the motor for a first predetermined period of time to close the valve when a parameter is sensed as above a first value, a second circuit, Fig. 2, supplying current for a second predetermined period of time to open the valve when the parameter is sensed as below a second value lower than the first value, the second circuit also including a spark ignition device with means for deactivating it when the fuel is lit. The appliance may be a gas fired lighting burner which is switched on when a photodiode 30 senses ambient light below a given value (which may be selected by varying resistor 33) and thus biases transistor 32 to render it conductive, causing capacitor 34 to be charged; when the voltage on the capacitor is sufficient to cause a Zener diode to bias thyristor 43 charging ceases (so that the drain on the power source 31 is minimized), and the capacitor discharges (in a time determinable by a variable resistor) rendering transistor 36 conductive so that current flows in winding 25 of the motor (10) to open the gas supply valve (11); current also flows by way of resistor 37 to operate ignition spark generator 39. When a flame is sensed by negative temperature coefficient resistor 41 transistor 40 is rendered non-conductive and the sparks cease. If the burner fails to ignite then capacitor 47 will become charged to a voltage such as to actuate Zener diode 48, actuating a relay which shuts off a supplementary valve in the gas supply. The first circuit. Fig. 1 (not shown), which closes the valve (11) when a photodiode (12) senses ambient light above a given level, is analogous to the valve-operating part of the second circuit of Fig. 2. Alternatively, Fig. 4, the second circuit may comprise two monostable elements each constituted by a pair of NAND gates connected by a RC timing circuit, one element receiving a signal from a light-sensitive device 59 and supplying current in buffer amplifiers 63, 65 to motor winding 58 and to a spark generator, and the other element receiving a signal from a heat sensitive device 66 and supplying current to the amplifier 65 (but decoupled from the amplifier 63 by diode 64) to reignite the burner should it be extinguished while gas is being supplied. A safety circuit incorporating a spark counting device may interrupt the gas supply if there is no ignition. The first circuit of this embodiment, Fig. 3 (not shown) is analogous to the relevant part of that of Fig. 4. The applicance may alternatively be a heating burner controlled by a thermistor sensing ambient temperature.
