Title: Improvements in or relating to electric clocks
IPC: G04C3/027
Filed: 1932-11-11
Abstract: 408,725. Electric clocks. BROWN, T. A., 53, Swinderby Road, Wembley, Middlesex. Nov. 11, 1932, No. 31948. [Class 139.] An electric clock in which the circuit of an electromagnetic device for re-energizing the pendulum is opened and closed by the pendulum, one contact being fixed to the frame and the second being pivoted on the pendulum and below the first contact, is characterized in that the second contact is the prong of a fork and the fixed contact is situated between the prongs of the fork. Pivoted to the pendulum 14 at 25 is a fork 22 with prongs 23, 24, of which the former prong contacts with fixed contact 18 on an arm 19 fixed by pin-and-slot connection 42, 43 to an arm 36. The other prong 24 coacts with insulation 21 only. Offsets 28, 29 on fork 22 and studs 26, 27 on the pendulum limit the rocking of the fork. The electromagnet 20, the circuit of which is completed by contacts 18, 23, is adjustably carried on the arm 36, which latter is itself adjustably fixed to frame plate 10 by slot 39 and stud 38. As the pendulum passes through its zero position the prongs 23, 24 alternatively contact with, and then fall away from, parts 18, 21 so that contact 18, 23 is made once for each complete swing of the pendulum. The armature 33 of the magnet 20 is on the pendulum and in the left hand position of the pendulum forms, with the casing 32, a complete casing for the magnet which is closed at both ends. As the pendulum oscillates, two pins 46 thereon oscillate an arm 45 rigid with a notched disc 44, whereby the notch allows the upward movement of a roller 58 on a bellcrank 51, 50 which is pivoted at 52 and carries a pawl 54 which advances the seconds wheel 56. In a modification the armature is mounted on a member pivoted coaxially with the pendulum and rigidly linked thereto. This member is U-shaped and the contact fork is pivoted between the limbs of the U. A snap spring mounted on the frame plate coacts with a pin on the fork to hold the contact closed as long as possible.

Abstract: 209,085. Soc. Cuenin & Co., (trading as RenÚ, G.). Dec. 27, 1922, [Convention date]. Colour photography; printing apparatus.-A camera for producing at one exposure three component colour negatives comprises an objective and two colour screens meeting at an angle, and equally inclined to the. axis of the objective, the screens being so arranged that the beam of light from the objective falls on one screen, which transmits a part directly to a photographic plate and reflects the remainder to the second screen, which in turn transmits a part directly to a second plate and reflects the remainder directly to a third plate. The camera has a single lens 0, Fig. 1, projecting an image upon a sensitive plate C' by rays transmitted through a glass screen M<1> mounted in an opaque screen E<1> inclined at 45‹ to the axis of the lens. Rays refiected from the screen M<1> form the second image upon a sensitive plate C<2> after transmission through a similar arrangement of screens M<2>, E<2>, and rays reflected from the screen M<2> form the third image upon a sensitive plate C<3>, The screens M<1>, M<2> are coated with coloured varnish, for example orange-red and green respectively. The plates C<1>, C<2> are sensitive to the colours transmitted by these screens, and the plate C<3> is an ordinary plate employed without a filter. The Specification as open to inspection under Sect. 91 (3) (a) also comprises a method and apparatus for printing from the partial negatives. A positive is printed on bromide paper coloured yellow from the negative obtained from plate C<3>, and positives are printed in register on opposite sides of a doubly-coated non-actinic film-support from the negatives obtained from plates C' and C<2>. The film positives are coloured, in the example chosen, one red and one blue, in baths of which the film forms the bottom, and the film, or its faces, are then superimposed in register on the yellow positive. The apparatus for producing the film positives comprises a negative frame D', Fig. 2 (Cancelled), having a hinged extension L', and a negative frame D<2> having a fixed extension L<2>, the frames being held together in an adjustable manner bv screw-pins T<2>, fixed to the extensions L<2>, passing loosely through holes 0' in the extension L<1>, and provided with clamping-nuts V<2>. The frames are adjusted until the negatives in frames D<1> and D<2> are in register, the extensions are clamped together, the film with sensitive layers on opposite sides is placed between the frames, and printing is effected from opposite sides. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to power actuators or servomotors
IPC: B60T13/24
Filed: 1925-12-24
Abstract: 245,444. Bragg, C. S., and Kliesrath, V. W. Jan. 5, 1925, [Convention date]. Fluid-pressure.-Ina power actuator or servomotor comprising a cylinder and double-acting piston with a connection to a vacuum-producing means, the parts are arranged so that a partial vacuum is maintained at both sides of the piston when it is in the normal inoperative position and the cylinder acts as a storage chamber, actuation of the piston being effected by admitting air to one end of the cylinder. The apparatus is adapted to be connected to the induction pipe of an internal combustion engine and used for operating the brakes of the vehicle carrying the engine. The supply pipe 62 of the servo-motor 1 is connected to a hollow rod 20 to which a brake lever is also secured. The rod 20 is connected by a collar 22 with a tube 20a sliding in the hollow piston rod 5 which is open to the air at 29 and has an eye for the connection of the brake lever. On the rod are two sets of two valves 40 - - 43 co-operating with seats 13 - - 16 in the boss of the piston, with a vacuum chamber 17 and passages leading to the cylinder. Each pair of valves has a central rubber or similar cushioning member 50 which retain the valves on their seats when the control rod is central in the piston. Movement of the control rod results, in consequence of the abutment of the collar 22, in one of the central valves 'being forced off its. seat to place one side of the cylinder in communication with the suction chamber 17 and one of the opposite outer valves also opens up the opposite side of the cylinder to the atmosphere. The seats 14, 15 have springs 51 which are stronger than the cushions 50 so that when the control is central in the piston; the valves 41, 42 will be off their seats and thus place both sides of the cylinder in communication with the suction chamber 17. Instead of the springs 51, the rubber valves 41, 42 may be formed with slight corrugations which provide for leakage except when flattened by pressure upon movement of the control rod. In the normal condition with the piston at the outer end of the cylinder, it is sufficient to open up the right hand side to the left hand side by a valve on the piston or external valve on a coupling pipe which valve is opened by contact with the cylinder or piston respectively when the piston is in the retracted position the outer end. In a modification the suction valves are unseated, in the retracted position, mechanically as by forming free flanges on the central collar which can be moved separately from the main control. Specification 226,514 is referred to.

Title: Improvements in printing by blocking from foil
IPC: B41F19/06
Filed: 1953-11-25
Abstract: 752,553. Embossing. JONES, A., and REMPLOY, Ltd. Dec. 1, 1954 [Nov. 25, 1953], No. 32754/53. Class 100 (2). Plate-printing presses.- In a hand-operated press for colour or metal embossing a heated platen 6 is mounted on a carrier 8 pivoted to a bed 2 so that the embossing types 10 may be swung into and out of contact with an article mounted on the bed, the position of the pivot axis 20 being adjustable with respect to the bed so as to vary the clearance between the platen and the bed when their working faces are parallel. The pivot axle 20 is mounted in bearing blocks 22 in small vertical guides 24 which are fixed to the upper ends of threaded rods 26 passing through openings in the bed. Knurled nuts 28 captive in recesses in the bed are rotatable to adjust the height of the guides 24. Springs 32 bear downwardly on the blocks, the pressure being variable by screws 34. The pigmented or metallized foil 38 is drawn from a roll 40 braked frictionally by nut 46. The foil passes over a control pulley 50 and between feed rollers 52, 54. The control pulley, 50 is mounted on spring-loaded arms 18 pivoted to the carrier 8 and is adapted to hold the foil out of engagement with the platen 6 until it bears on the work. As the platen descends the roller 50 engages and rolls over the work 14 serving thereby to tension the foil across the working face of the platen. The foil feed roller 52 is driven through a pawl and ratchet by a gear 62 which is driven a certain amount after each embossing operation by the rising action of the platen carrier 8. A toothed quadrant 66 mounted on the carrier and meshing with gear 62 is adapted to engage, and be displaced by, a stationary adjustable abutment 72 as the carrier is raised to its uppermost position (shown in dotted lines). The article to be embossed is retained in position on the bed by spring clips 16.
