Abstract: 1,180,993. Desizing glass fibres. J. P. STEVENS & CO. Inc. 30 Sept., 1968, No. 36410/ 67. Heading D1P. [Also in Division C1] Sized glass fibres are desized and their strength may be improved by treating them with material comprising an anion decomposable by heat to provide oxygen, e.g. a chlorate or nitrate, sodium cation, and at least one cation of the group potassium, cesium and rubidium, and introducing them while dry, to a temperature of 600‹-1250‹F for a period of time at least sufficient to remove substantially all the sizing material as indicated by an ignition loss of 0.1% by weight or less. Sized glass fibre fabrics may be impregnated with an aqueous solution of the material, e.g. a mixture of sodium nitrate and potassium nitrate, dried, heat treated, and washed. Alternatively the material comprising sodium and potassium, cesium or rubidium salts and amino decomposable by heat to provide oxygen may be added to the size applied to the fibres after formation.

Abstract: 967,456. Optical projector dimming devices. VOIGTLANDER A. G. Oct. 27, 1960 [Oct.28, 1959], No. 36997/60. Heading G2J. An optical projector having a lamp and a concave reflector includes a dimming device comprising a cover which can be introduced between the lamp and the reflector and at least one other dimming member consisting of less than fully transparent material interposable in the light beam between the projection aperture and the objective. As shown, a spring-loaded lever 14 pivoted at 114 carries an opaque cover 11 and, upon energization of electromagnet 21 by pressing one of the switch-buttons in a switching box 25, escapes from the spring-loaded locking pawl 18 as the latter pivots anti-clockwise under magnetic attraction, the cover 11 riding up in guide 16 between reflectors 3 and lamp 2. In an exactly similar fashion neutral filters 12 and 13 carried on levers 27 and 35 respectively, both of which are pivoted at 28, may be introduced, by means of springs 29 and 36 acting on the respective levers, into the projection beam path, upon depression of further switchbuttons. The various buttons may be characteristically marked, for example by different luminous markings or relief patterns, such as pimples, for detection by touch. The switching box 25 may also contain switching controls for the projector. Slides or transparencies 7 stored in a magazine 10 may be pushed into and withdrawn from the gate 6 by means of a slide member 8. The latter carries a lug 26 which, on withdrawal of the slide 8 bears against the upper edges of the levers 14, 27 or 35, as the case may be, and depresses them on to the sloping heads of the locking pawls which are thereby pivoted against their spring loading and finally snap back to lock the levers. The levers may be operated separately or in any combination. In an alternative embodiment, the levers are arranged above the optical system and are gravity-operated when the locking pawls are released.

Abstract: 963,204. Semi-conductor devices. PHILCO CORPORATION. Oct. 28, 1960 [Oct. 30, 1959], No. 37119/60. Heading H1K. [Also in Division H2] An electrical device is sealed in an enclosure which has a hollow conductive terminal member projecting from it. Within the terminal member is a sleeve of malleable conductive material, and a flexible wire connected to the device is arranged within the sleeve. The member is then crimped to secure the wire in position. A transistor 10 is mounted on a conductive base 15 which is dished to prevent the transmission of mechanical stresses to the transistor. The transistor is enclosed in an envelope 12 comprising two cylindrical conductive shells 24, 25 with flanges 27, 28 and elongated terminals 30 secured concentrically with the shells by a fused glass seal 31. Each terminal 30 consists of a rigid outer member 32 of nickel-iron or chromium-iron alloy, having a closed longitudinal bore 35. Within bore 35 is a sleeve 34 of conductive soft metal, e.g. oxygen-free, high conductivity copper. The emitter and collector leads 16 of transistor 10 are inserted in sleeves 34 as the two halves of envelope 12 are brought together. The periphery of base 15 is simultaneously sandwiched between flanges 28 and secured by a cold-weld seam 29. Pressure is then applied to opposite sides of each terminal 30 to compress sleeve 34 and wire 16 into close engagement, causing them to fuse into a homogeneous mass. Leads 16, which may be of nickel, are formed with stressrelief bands 40 to prevent breaking.

Title: Improvements in or relating to a film strip printer
Inventor: BALINT ANDREW
IPC: G03B27/73
Filed: 1967-08-16
Abstract: 1,200,612. Film-strip printer; programme control. BELL & HOWELL CO. Aug.16, 1967 [Aug.17, 1966], No.37609/67. Headings G2A; G2C and G3N. A film-strip printer having red, green and blue light valves 184, 186, 188 controlled respectively by red, green and blue correction data recorded in sets on a tape, includes a tape reader 72 for reading the data of one of the sets during non- concurrent intervals of time; memories for storing the red, green and blue data read by the reader; means Figs. 3A, 3B, 3C, (not shown) for simultaneously setting the light valves when stored data is recovered from the memories; and means responsive to signals from a cue signal generator to cause the tape read to read another set of data while the valves are being set in accordance with the first-read set. Printer White light from a source 1 is split by dichroic mirrors 2, 3 into red, green and blue beams passing between vanes 11, 13, 15 of the light valves 184, 186, 188, respectively set according to the appropriate correction data. The corrected beams are recombined by dichroic mirrors 4, 5, 6, 7 and, after passing through a lens 8, aperture 9, and film-strip 17 prints a film-strip 19. The filmstrip 17 comprises several scenes each requiring different colour correction, and the tape (35) Fig.2 (not shown), has been appropriately programmed. A cue, e.g. a notch, between successive scenes of the strip 17, gives rise to a signal which causes the light valves to be re-set. Circuit Operation Figs.A, B (not shown). Depression of a start button closes contacts (32A) and causes a clock (46) to produce a sequence of output pulses to step the tape through the reader until a start-8 hole is sensed. This generates a start-8 pulse which enters a counter (58) and also a 100 milli-second delay (160). There is a feedback circuit from the counter to the clock so that the clock will produce three more pulses only to advance the tape and counter. This means that correction data relating to scene 1 of the strip 17 is read from the tape and stored in the memories (260, 262, 264), vane cams in each valve being rotated appropriately. The vanes are not set and the control circuits are at rest intil the termination of the 100 milli-second delay interval. Approximately 100 milli-seconds after the start-8 hole was sensed, the control circuits begin a second cycle of operations in response to a signal from delay element (160). The vanes 11, 13, 15 are set in accordance with the vane cam positions and correction data relating to scene 2 is read from the tape to set the vane cams to new positions. Successive cycles of circuit operations are started by a micro-switch 69 sensing a cue notch in the film 17. The printing operation is stopped automatically if the tape reader gets out of step with the counter.

A rotary horizontal-drum type washing and spin-drying machine has a drum which is reversibly driven during washing and is driven, during spin-drying, in the same direction as the last direction of rotation in the washing process, and a water level switch 7 in the circuit of the spin-drying motor M, or in a control circuit therefor, is opened when the water in the washing drum is below a predetermined level. A holding switch 11 connected in parallel with the switch 7 is closed when current first flows through the switch 7 and remains closed until a switch 6 is opened at the end of the spindrying process. A switch 3 effects the changeover to spin-drying. A periodically-acting switch 12 is closed when the washing drum is rotating, during washing, in the same direction as during spin-drying. The switch 3 can therefore only be operated when the switches 7, 12 and 6 are closed.
