Filed: 1972-08-02
Abstract: 1399506 Electro-photographic member DAI NIPPON TORYO KK 2 Aug 1972 36160/72 Heading G2C A reusable electro-photographic plate comprises a conductive base 1, a photo-conductive layer 2 and an insulating layer 3, the photo-conductive layer comprising CdS and an activator in a polymer binder having a volume resistivity of 10<SP>12</SP> to 10<SP>16</SP> ohm. cm. and a specific dielectric constant of not more than 4, and either the base 1 or insulating layer 3 being transparent to the radiation to be used. In the photo-conductor, Cd may be partially replaced by Zn, and S by Te. The binder may be polyvinyl acetate, polyvinyl butyral, chlorinated rubber, polystyrene, acrylonitrile/styrene polymer, and the insulating layer may be polystyrene or polyethylene terephonalate. To form a latent image the device is exposed to illumination while a corona discharge is simultaneously applied. So long as the insulating layer is not positively charged and the zinc proportion is not too high the device will not show persistent internal polarization because the insulating layer suppresses movement of free electrons in layer 2.

Title: Improvements in or relating to the winding of coils for dynamo electric machines
IPC: H01F41/08
Filed: 1937-12-30
Abstract: 502,757. Coil - winding apparatus. KURSTEINER, E. Dec. 30, 1937, No. 36162. Convention date, Jan. 6. [Class 35] A Gramme ring winding is wound in the slots 28 of an annular iron core 26 by means of a machine comprising a rotating magazine wheel 11 passing through the bore of the core and carrying the conductor 17 and insulating material 16; the core is adjustably supported as by clamps 22, 23 so that it can be rotated to apply the winding in consecutive slots. The magazine wheel has two grooves in its periphery for the reception of conducting and insulating materials in strip form and the bottoms of the grooves have rollers to enable the stored materials to run freely. The wheel is divided on the lines 12, 13 to enable it to be passed through the core, and is mounted on bearing rollers 7 ... 10a. The materials stored in the magazine wheel pass out through openings in the bottoms of the grooves and are pressed into position in the core slots by fingers 29 ... 32. Each of these fingers is actuated by cam &c. mechanism driven by the pulley 33 in such a manner that it follows and remains in contact with the conductor along one side of the core until the next finger in sequence comes into operation. At the end of its operative movement, and before returning to its initial position, each finger is moved out of the plane of the coil to avoid fouling the wire during the application of the next turn and is also moved outwards in the plane of the coil through a distance equal to the width of one layer of conducting material and one layer of insulating material. The core may be produced by winding an iron ribbon. Specification 440,571 is referred to.

[Class 57.] In a centrifugal governor the weights 4a, 4b are mounted upon an arm 4 pivoted at 3 to the governor spindle 1. Mounted in projections 20 on the weight arm are cam faces 19 upon which bear rollers 15 secured to the sleeve 7.

The loading spring 10 is arranged between the sleeve and an abutment 11 and the movement of the sleeve is transmitted by a bell crank 16 and levers 21, 22, 25. An eccentric 23 adjusts the particular part of the cam face with which the roller contacts. The cam faces may be changed to vary the characteristics of the governor.

Title: Wire printer
IPC: B41J2/27
Filed: 1955-12-21
Abstract: 815,813. Selective printing. INTERNATIONAL BUSINESS MACHINES. CORPORATION. Dec. 21, 1955 [Dec. 30, 1954], No. 36610/55. Class 100(4) In a wire printer, the guide tubes 88 extend from a wire set-up mechanism to a movable print impact head 94 in two sweeping curves. This construction provides a greater resistance to longitudinal displacement of individual print wires 36 at the time of impact, and because of a lower inertia level than wires with heavier inertia slugs it is easier to move the wires for setting. The setting mechanism comprises a control rod 37 which, after longitudinal and rotative setting, is transversely moved to shift the wires by members 74, adjustments 72, and arms 70 on a shaft 62 rocked by followers 64 engaging a double cam 54. After printing action by the cam 54, the wires 36, although partly restored by the printing impact, are reset by a flange 80 or the rearward edge of the bail which engages low mass inertia slugs 82 secured to the respective print wires 36. Specification 763,407 is referred to.

[Also in Group XXXVI] A process for the provision of terminals on disc-type capacitors 18 or other components comprises threading hair-pin shaped wires 12 through pairs of apertures 16, 17 in a supporting strip 11 and bending the free ends 14, 15 of the wires at right angles into overlapping relation as shown. Capacitors are then inserted between the ends of each hairpin so as to be held in position by the resilience of the hairpin with the wire ends 14, 15 contacting opposite metallised surfaces of the disc 18. The strip of capacitors is then passed through flux and solder baths to dip-solder the wires to the capacitors after which an insulating coating is applied to each capacitor. Finally the rounded ends 13 of the hairpins are cut off leaving separate terminal wires attached to the capacitors. The latter may then be packed still attached to the strip and prior to this the strip may be passed over a wheel having contacts engaging in the holes 16, 17, and hence the terminal recesses, to test the capacitors. Fig. 10 shows another embodiment wherein the strip 31 has rectangular apertures 32, 33 and slits 34 for the reception of the hairpins, the rounded ends 35 of which are bent over the adjacent edge of the strip and pressed towards the strip so as to grip the latter. After attachment of the capacitors as before, the ends 35 are cropped off, for example, by cutting the strip along the slits 34, and the capacitors are pushed towards the strip so as to seat in the apertures 32, 33. Specification 798,778 is referred to.

Inventor: O'NEIL WALTER KENNETH
IPC: H03K17/73
Filed: 1965-08-27
Abstract: 1,153,136. Thyristor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 26 Aug., 1966 [27 Aug., 19651, No. 36872/65. Heading H3T. In a switching system wherein the direct current in a load 4 is controlled by repetitively triggering and quenching a thyristor CR1, the thyristor is quenched by a circuit comprising a pulse forming network PFN in series with a further thyristor CR2. As described, when CR1 is conductive and the PFN charged to the polarity shown, CR2 may be triggered so as to provide a negative rectangular voltage pulse from PFN to the anode of CR1 of sufficient duration to quench CR1. PFN then becomes charged with reverse polarity because of the inductance of load 4, the overswing quenching CR2. When CR1 is again triggered, the energy stored in PFN flows through CR1, D1 and L1 so as to restore the charge on PFN to the polarity shown. The average value of current in load 4 is thus controlled by varying the timing between the triggering of CR1 and CR2.
