Abstract: 724,702. Smoothing direct current. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. March 10, 1953 [March 31, 1952], No. 6536/53. Class 38 (2). To eliminate A.C. from the D.C. supplied to a load R, the supply and the load are connected at S1, S2 and B1, B2 to opposite terminals a, c and b, d respectively of a four-arm bridge, each arm having the same A.C. impedance, and the same phase angle, but two opposite arms are blocked to D.C. by capacitors C1, C1<SP>1</SP>, while the provision of transformers T, T<SP>1</SP> in the other arms to supply capacitors C, C<SP>1</SP> allows the circulation of D.C. The resistances R1, R1<SP>1</SP> in the blocked arms are made equal to the copper and iron losses in the other arms. As the terminals b, d are at the same A.C. potential, no A.C. flows through the load R, but D.C. is free to flow through the path a, b, d, c. The transformers may have a common iron core M preferably with an air gap G to stop D.C. saturation, and a single secondary winding Sc supplying a condenser C2, Fig. 3. The circuit may be used in a single-trail track signalling circuit to block A.C. both from the relays and the D.C. sources, Fig. 4 (not shown).
Patent GB-637215-A (GB)
Title: Improvements in and relating to clockwork-operated time fuzes
IPC: F42C9/04
Filed: 1948-03-02
Abstract: 637,215. Projectile fuzes. DELAY, F. March 2, 1948, No. 6588. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 2, 1948.] [Class 9 (i)] The spring-urged striker 5 of a clockwork fuze is held in a retracted position by an oscillating lever 8 which has an aperture through which the striker is allowed to slide only when the lever is allowed to turn, under the action of the striker itself, by the provision of a notch 2b of a surrounding rotary member 2. Further, at least one safety bolt 11 is provided between the aperture in the lever 8 and the primer to prevent the striker from functioning when lever 8 is accidentally released, the bolt in such event being held by the striker itself against outward movement under centrifugal force to the release position. In the form shown, a bevelled edge 5a of the striker coacts with a similar surface on lever 8 to cause the latter to turn about its pivot, but the lever is normally held by a pawl 4. In setting the fuze, the member 2 is rotated clockwise and itself moves the pawl away from lever 8, the latter subsequently being held by the inner wall of the member 2. During flight, the clockwork mechanism moves the member 2 back to its original position, and as the pawl is held away from lever 8 by centrifugal force the striker is released when the lever 8 registers with the notch 2b of member 2. Two members 11 are provided, each having a semicircular opening to provide between them a circular hole in which a reduced part 5b of the striker can fit. The members, which are acted on by springs 12a, 12b, move to the release position under centrifugal force, but during transport serve to prevent complete movement of the striker. The engagement of the striker, in such event, in the semicircular apertures prevents the members 11 from moving outwardly.

Abstract: 1,090,793. Builder-motion. T. M. M. (RE SEARCH) Ltd. March 7, 1966 [April 16, 1965], No. 6678/65. Heading D1D. In a builder motion for a draw twisting machine having switching-means controlling the direction in which a traverse-rail is driven, the switching means comprises two differential mechanisms each having a first input member oscillated synchronously with the movement of the rail, a second input member responsive to build-adjusting mechanism, and a rotary output member, the output member in one of the differentials acting to reverse the drive at one end of the traverse stroke, and the output member in the other differential acting to reverse the drive at the other end of the stroke. The ring-rails, one at each side of the machine are reciprocated by a piston 12, Fig. 1, working in a cylinder under the control of a reversing slide valve 64. To this end, the rails are carried by racks reciprocated by pinions rotating one way or the other according to the oscillations of shafts 21, 23 produced by pinions 20, 22, these being themselves oscillated by racks 14, is moving with the piston. The pinion 22 is geared to two interconnected gears 32, 33, Fig. 3 which are the input members of two differentials through which the reversing valve 64 is actuated. Each differential also comprises a second input member (40, Fig. 4, not shown) and an output member (39) in one with an arm 43 or 57, Fig. 3, each having a pin 44 or 58. As the output members revolve, these pins engage in turn abutments 59 or 60 to rock one way or the other a lever 61. This has a bowl 62 alternately engaging collars 65, 66 on the actuating stem of the valve 64. Spring-loaded toggle-links 68, 69 ensure quick reversals of the valve. In each differential, the second input member (40) is connected to a drum (42) through which a factor corresponding to the build it is desired to impose on the package, is fed into the differential. To this end the drums are each connected, for rotation in opposite directions, by a steel tape to the profiled end of a pivoted cam-lever 47 or 52 of which the other end carries a follower engaging a cam 72 or 73. The cams are rotated by wheels engaging worms on a shaft driven from a reducing gear box 81. To change the build, the cams may be changed for others, while the ratio transmitted in the box 81 can be varied.

Filed: 1974-02-14
Abstract: 1462637 Camera NIPPON KOGAKU KK 14 Feb 1974 [19 Feb 1973] 6780/74 Heading G2A A camera has a light metering circuit 11  connected to a storage circuit 12 by a switch 14, a battery 10 connected to circuits 11 and 12 by a power switch 1 and a mechanism which prevents switch 14 from being opened unless power switch 1 has been closed. This prevents circuit 12 from storing a zero signal. As shown rotation of a lever 8 anti-clockwise releases a lever 3 which is rotated anti-clockwise by a spring so that a pin 4 closes power switch 1. This movement of lever 3 clears the path of a lever 16 so that when a lever 20 is rotated clockwise lever 16 can also rotate clockwise whereby a pin 17 opens switch 14. Also when lever 16 is in this position, i.e. with switch 14 open, it blocks movement of lever 3 and thereby prevents re-opening of power switch 1. Circuit 12 is connected to an exposure control circuit 13 which is energized by a switch 22 coupled to a reflex mirror (not shown).

Title: Method and apparatus for detecting particles
IPC: G01N15/02
Filed: 1972-02-14
Abstract: 1376017 Optical detection of particles GRETAG AG 14 Feb 1972 [17 Feb 1971] 6821/72 Heading G1A [Also in Division G2] Particles 2 Fig. 1 on a support 3 are detected by wetting the particles with a liquid layer I having a depth d less than the maximum height H of the particles, projecting a light beam L on to the layer and measuring the light scattered L' by the particles with a Schlieren or phase contrast system S. The wetting may be achieved by flowing on a liquid or by applying a thermoplastic layer over the particles on the support and then heating the thermoplastic until it liquefies and wets the particles. The liquid may be a silicone oil of viscosity 2-6 centipoises. To detect particles of different size the process is repeated with layers of different thickness. The different thicknesses may be achieved either by directly spreading the layers over the support, or allowing controlled evaporation of a layer or, with a vertical support allowing liquid to flow off the support at a controlled rate. In a further embodiment, Fig. 3 particle covered support 3 under a cover 22 is pushed into a mating aperture in a housing 20. The cover is removed by a suction cup 23 and then the desired layers of wetting liquid applied to the support. The intensities of the scattered light, signifying at the different layer depths particles of varying sizes, are detected by a photo-electric transducer 100 which feeds the information to an electronic evaluating system 11.
