Title: An electromagnetic regulating and driving device for a clock
IPC: G04C3/06
Filed: 1967-02-24
Abstract: 1,140,317. Electric clocks. ITALORA S. p. A. Feb.24, 1967 [Dec.5, 1966], No.9008/67. Heading G3T. An electromagnetic driving and regulating device for a clock comprises at least four magnetic poles 5 and at least two coils 6, 7 connected to an electronic amplifier Atr. The coils 6, 7 are stationary whilst the magnets are attached to one of the two discs 3 comprising the balance wheel. The discs 3 are connected by a cylinder (4), Fig. 2 (not shown), both the discs and the cylinder being made of a material of high magnetic permeability. The arrangement of the six poles 5 is such that during each complete oscillation, two pulses are induced in each coil as the balance wheel passes through its rest position. However the pulse induced during the clockwise oscillation is of opposite sign to the pulse induced during the reverse oscillation so that one of the pulses will not trigger a transistor in the amplifier Atr. The amplifier may include an NPN and a PNP type transistor, in which case both pulses may be used as driving pulses. In modifications four and eight magnetic poles are used and the magnetic poles may be formed by radially polarizing the balance wheel.

Title: Improvements relating to brake mechanisms
IPC: B66D5/26
Filed: 1956-03-22
Abstract: 815,435. Mine conveyer brakes. SINCLAIR, H. March 21, 1957 [March 22, 1956], No. 9045/56. Class 103 (1). In a brake mechanism, such as is used for mine conveyers, wherein the conveyer 10 is driven by a motor 2 through an hydraulic coupling 3, the brake shoes 20, 21 being applied to a drum 14 rotatable with the conveyer by a weight 26 and released by an electro-hydraulic thrustor device 24, the normal direction of rotation of the drum is according to the arrow marked in Fig. 2. When power is cut off the motor 2 and the drum braked to a stop, due to the hydraulic coupling 3, the drum may run back slightly according to the arrow shown in Fig. 3, this movement is used to produce a slightly anti-clockwise movement of shoe 20, deflecting its mounting on resilient plate 19 and causing a tappet 28<SP>1</SP> on the post 15 to operate through lever 29 a switch 28 to cut off current to the thrustor 24, as shown in the circuit in Fig. 5. If the switch 38 is closed to energize motor 2, the switch 28 will remain open and prevent the release of the brake by the thrustor until sufficient torque has been built up through the coupling 3 to return the shoe 20 to its normal position.

Abstract: 1,114,250. Feeding sheets. ENGLISH NUMBERING MACHINES Ltd. 2 March, 1966, No. 9072/66. Heading B6B. In apparatus for separating sheets from the top of a stack 102, the top sheet is first bulged relatively to the stack by means of a clamp 132, and a movable wiper 108 which is moved towards the clamp. As described, the apparatus is used to deflect upwardly the leaves of a book 102 carried on a movable support 3 urged by spring means in the direction A to clamp the free edges of the book against a fixed abutment 107. A rubber wiper pad 108, engaging the top leaf of the book, is carried by a bracket 114 which, together with two opposed leaf springs 115, 116, is secured to a pivotal shaft 119 mounted in side plates 120. The plates 120 are pivotal about a shaft 122 by means of a camfollower 123, 125 engaging a cam 135 which is secured to a drive shaft 136. The cam-follower is urged against the cam 135 by a spring 26 anchored on one of a pair of arms 128 which are secured together by pins 129, 131. The arms 128 are secured to the shaft 122, and carry a rubber clamping member 132 on a resilient mounting 134, and the member 132 is urged against the book 102 by cam means which rock the shaft 122. The leaf spring 115 engages the pin 129 and urges the wiper 108 against the top leaf of the book 102; but this pressure is relieved by the engagement of a bent plate 151 with the opposite leaf spring 116. The plate 151 is carried by cam-follower 146, 147 engaging a cam 143 fixed on the drive shaft 136, the follower beng pivotal on the shaft 122. In one cycle of operation, as the shaft 136 rotates, the rubber wiper pad 108 moves upwardly along the book to bulge the top leaf, and then moves downwardly. The plate 151 is now caused to relieve the pressure of the pad 108, so that if a second leaf has been bulged it will fall back. The pad 108 again moves upwardly so that only the top. leaf is bulged.

Title: Improvements in and connected with presses for the plastic deformation of metals
IPC: B21C23/21
Filed: 1953-04-07
Abstract: 730,828. Forging; stamping. KABELUND METALLWERKE NEUMEYER AKT-. GES. April 7, 1953 [April 10, 1952; April 10, 1952; April, 10, 1952; Feb. 23, 1953], No. 9355/53. Class 83 (4). In a metal-working press for forging, cupping, deep-drawing, embossing, &c., the work is deformed between a tool and a die both of which are carried by slides driven so that the tool carries out the required working stroke with the die stationary and is then retracted while the die also withdraws to allow removal of the work and the insertion of a fresh blank. A horizontal press comprises a casing 5 to which is bolted an extension 42 forming the press bed and having guides 4.1, Figs. 1 and 4, along which reciprocate slides 40 and 66 carrying respectively a punch or mandrel and a die. In the casing 5 is a shaft 13 driven by a belt 7 from a motor 1 adjustably mounted on the casing. The shaft 13 is connected to the pulley by a coupling interconnected with a brake so that if the drive is disconnected, the press is stopped. The shaft drives, through intermediate gears, two gears 29 which are keyed to a shaft 28 and to which are secured eccentrics 33 serving to reciprocate .the slide 40 through connecting rods 36. Each eccentric 33 has two bores 34 and 35 enabling two different eccentricities to be obtained. Also mounted on the shaft 38 between the eccentrics is the common hub of two sets of toggles 65a, 65b, by which the die holder slide 66 is reciprocated. The toggles are actuated by a member 58 carrying a roll 60 spring urged into contact with a cam 57 keyed to a shaft 56 geared to the shaft 28. A mandrel or other tool can be adjusted axially in the slide 40 by a screwed sleeve 48 rotated by a hand wheel through bevel gears 49. The steps in a cupping and in a piercing operation are set out in Figs. 14 and 15 (not shown). In a modification, the press is arranged vertically, the slides 40 and 66 being moved along. guides 72 between vertical frame members 70, Fig. 8, bolted to the top of the casing 5. Instead of being mechanically actuated, the toggle joint 64 may be coupled to the rod 73 of a piston 75 in a cylinder 74, Fig. 11, pressure fluid being supplied to either side of the piston through hollow journals 75a and 75b by which the cylinder is mounted in bearings 76 and by which it is connected to a known type of pump, Fig. 12, whose output is controlled by tilting the portion 80 relatively to the driving spindle 82. Spindle 82 is driven from the shaft 13 and the body 80 is racked, within the limits set by adjustable stops 108, Fig. 13, by a rod 103 reciprocated through a flexible spring coupling 102 from a cam 100 on a shaft, 99 also driven from the shaft 13. In a modified form, the body 80 is rocked by the rod of a piston in a cylinder supplied_ with pressure fluid at either end under the control of a camoperated sliding valve.

Title: Improvements relating to microwave electron discharge apparatus
IPC: H01J25/00
Filed: 1955-04-01
Abstract: 788,323. High frequency discharge apparatus; particle accelerators. BRITISH-THOMSONHOUSTON CO., Ltd. (General Electric Co.). April 1, 1955, No. 9591/55. Class 39(1). Electrons are accelerated up to ¢c by cyclotron action, and interact with a waveguide structure at the periphery of the orbiting space to generate or amplify oscillations. The cyclotron consists of a pair of electrodes 2, 3, Fig. 1, each with a semi-circular hollow portion which together make up the orbiting space 4, and an emissive filament 5. The waveguide structure includes a waveguide section 15 and coupling slots 16. The slots 16 also serve the purpose of reducing the velocity of the waves to match that of the electrons. An alternating voltage is applied across the accelerating gap 10 by means of a resonant cavity 11 which is excited by a probe 12. A similar resonant cavity 14, which requires no external excitation, is provided at the other end of the gap for better excitation of the gap. Oscillations are transmitted through a slot 17, resonant chamber 18 and a resonant window 19 to an output connection 20. In an amplifier, any tendency to oscillate is suppressed by placing an attenuator 21 within waveguide 15 ; input signals are fed in through an input connection 22, a resonant window 23, a resonant chamber 24 and a slot 25. In a modification, Fig. 4, the waveguide structure consists of a ring 42 of dielectric material. A metal coating 44 prevents the accumulation of undesired charges from electrons which strike the inner surface of the ring. Wires 41 facing the filament 40 are connected to electrode 36 to aid the initial acceleration of the electrons across the gap. There is a collector electrode 45. Output connection 42 is a piece of dielectric, and so is the input connection in the case of amplifier. In other modifications the waveguide structure is a helix, or the slots 16 of Fig. 1 may lead into the waveguide 15 from resonant cavities which face the orbiting space. Specification 5191/39 as open to inspection under Sect. 91 of the 1907-46 Patents Act is referred to.
