[Also in Divisions G4 and H3] A circuit for monitoring a consumer circuit, such as a vehicle lighting circuit C, Fig. 1, comprises an oscillator O having its output connected to the consumer circuit, and also to an indicator circuit K, the arrangement being such that the consumer circuit C has a low impedance at the oscillator frequency, thereby serving as a shunt for the indicator circuit K and preventing the development of a voltage therein. As described, the vehicle headlamp 1 and fuse 2 form a low impedance path across the output winding 3 of the transformer of a transistor blocking oscillator, thus preventing the circuit from oscillating. Should the fuse 2 blow, or the lamp 1 go open circuit, the circuit commences to oscillate providing a potential to light lamp 13. The circuit will function irrespective of whether the switch 15, supplying power to the lamp, is closed or not.

The agglomerate may be extruded to form elongated articles such as filaments or tubes. Where the compounds consists wholly or, substantially wholly of iron oxide a reduction temperature 500-650 C. may be used and a sintering temperature of 100-1250C. For copper oxide the respective temperature and 300-425C. and 850-1050C. and for tungsten or molybdenum oxide 550-1100C. and 1450-2800C. non-reactive, non-volatile materials harder than the metal produced may be included in the agglomerate, e.g. a fine dispersion of elemental tungsten in copper oxide. The binder is preferably an aqueous solution of an organic compound, e.g. an aqueous gel such as of starch and water. A solid reducing agent such as carbon may be included in the agglomerate. In the case of a agglomerate based on iron oxide the agglomerate may be heated in a carburizing atmosphere to introduce carbon into the sintered article.

Abstract: 1,228,022. Making holograms. EASTMAN KODAK CO. April 11, 1968 [April 14, 1967], No. 17445/68. Heading G2J. In a method for producing a multiple hologram for recording information, a source beam of coherent radiation is divided into a reference beam and an object beam which object beam is directed at a radiation impeding medium having a plurality of regularly spaced and substantially identical zones, which zones have a different impedance than the space between the zones, effectively to separate the beam into a plurality of signal beams of corresponding wavelength and polarization, the beams are directed along separate paths and caused to intersect with and interfere with one another and the reference beam in the same predetermined area of a recording medium to produce a plurality of line patterns of individually unique spatial frequency on the medium. A coherent beam from a laser 11 is conventionally split at 17, with the reference beam being directed on to the surface of a film 15 by a mirror 19. The other beam is directed on to a lenticular film base 21 having 25 lenticles per mm, which produces a line configuration having up to 30 beams. Each of these beams is then directed on to the same area of the film 15 by mirrors 24. The mirrors 19 and 24 are positioned on the perimeter of a plane ellipse having one focal point at the recording area and the other at the point at which the source beam impinges on beam splitter 17. To increase the amount of information recorded two lenticular film bases can be arranged coaxially but with the lenses mutually perpendicular to each other. This would give at least 900 separate beams. Alternatively the lenticular film base 21 may be replaced by a device consisting of a plurality of mirrors in place of the lenses so that the beams are formed by reflection.

Adhesion is effected by flamebonding, needling, treatment of the surface with a suitable solvent, by heat and pressure alone, by means of an interlayer of adhesivesaturated open mesh fabric or by means of a discontinuously-applied adhesive such as a natural rubber latex, a poly-chloroprene latex, a graft copolymer of natural rubber and polymethyl-methacrylate, ethylene/vinyl acetate copolymer, solvent based neoprene, a polyurethane, a carboxylated styrene/butadiene copolymer or a mixture of a styrene/butadiene copolymer and a phenol-aldehyde resin. The flexible sheet material may contain a binder impregnant, which does not permeate the compressed sheet, such as a natural or synthetic elastomer, e.g. a butadiene copolymer, or flexible thermoplastic, e.g. P.V.C., polyurethanes and ethylene/vinyl acetate copolymers. It is used as a natural leather substitute in upholstery, shoes, clothing and handbags and also for curtains and other furnishing fabrics.

A feeding device for intermittently advancing a tape, web or film comprises a rotary feed member 40 having friction roller or pin wheel 20 and a ratchet-wheel 21. Positive drive means, comprising a reversible stalling electric motor (13, Fig. 1) and a spring (16), rotatably urges the rotary feed member 40 in a given direction (clockwise or anticlockwise), the amount of rotation being governed by an escapement mechanism. This mechanism comprises the ratchet-wheel 21 and a single pawl member 25 having first and second pawl arms alternately engageable with the teeth of the ratchet wheel. One or each pawl arm has one tooth engaging surface 41, 44 which prevents movement of the ratchet-wheel, and another tooth engaging surface 42, 43 which receives a driving force from one of the ratchet-wheel teeth, as the rotary feed member rotates, to move the other pawl arm back into engagement with the ratchet-wheel. In operation, electromagnetic means momentarily actuates the pawl member 25 to move a first (motion preventing) pawl arm out of engagement with the ratehetwheel 21, whereby the second arm moves into engagement therewith. Rotation of the ratchetwheel then moves the second pawl arm out of engagement with the teeth, whereby the first pawl arm is moved back into blocking engagement with the ratchet-wheel, thereby completing an increment of feed. In one embodiment, Fig. 2, the electromagnetic actuating means comprises a single magnet 31 with a pivoted armature 32 plus a return spring 29. In an alternative embodiment (Fig. 5), a magnet is provided on each side of the pivoted armature 32. The feeding device is suitable for a tape perforator, tape reader or telegraph recorder.
