Title: Improvements in and relating to electromagnetically-operated devices, particularly relays
IPC: H01H50/16
Filed: 1939-01-26
Abstract: 514,228. Electromagnetic relays. SOC. D'ELECTRICITE MORS, and LE GOFF, L. J. A. Jan. 26, 1939, No. 2731. [Class 38 (v)] In an electromagnetic relay or other device, the armature 3, 4, has teeth adapted to penetrate without making contact into the gaps between corresponding teeth in the pole pieces 5, 6. Contact is not made because of the drop in attractive force as the teeth enter the gaps. The armature is carried by two arms 1, 2 which pivot about an axis X, X<1> by a mounting consisting of blade springs 11, 12, 13, 14, fixed to the arms 1, 2 and to fixed parts 9, 10 of a frame as shown. Each blade spring may consist uf a number of elements such as 11a, 11b, 11c, Fig. 3, arranged so that each passes through the axis of rotation. In modifications, the lengths of the portions of a spring on either side of the axis X, X' are unequal, Fig. 4 (not shown) or the two springs 11, 12, may meet in a block fixed to the part 1, Fig. 5 (not shown).

Title: Improvements in or relating to apparatus for making soil pots
IPC: B28B11/10
Filed: 1952-02-04
Abstract: 733,423. Endless belt conveyers. CRYER, W. A. May 4, 1953 [Feb. 4, 1952], No. 2904/52. Class 78 (1). [Also in Group V] A continuous process of making planted soil pots (see Group V) comprises feeding soil as a continuous stream along a trough 1, separating successive lengths from the leading end of the stream, inserting seedlings in the lengths of soil and compressing them by tools 15. The feeding is assisted by a conveyer band 3 along the bottom of the trough which may have slats to assist in gripping the soil, the sides of the trough being raised to allow the edges of the conveyer to pass beneath them. Conveyer bands 6, driven by pulleys 8, form the sides of the trough, passing round end pulleys 7, 9 and converging somewhat between the pulleys 7 and 8. The pulleys 7, 8, 9 are mounted on plates 37 which are adjustable towards and away from one another. Plates 38, 39 for sumpporting the side conveyer belts 6 are fixed to the plates 37. The pulleys 8 are driven, through sprockets on their shafts, by a chain 22 passing round a main driving sprocket 23. The shaft of the sprocket 23 is driven by a belt 27, from a shaft 25 extending from the motor 24, which passes over pulleys on a shaft 29 and which may be adjusted for tightness by moving the shaft of the. sprocket 23 in a slot 36. A drum on the shaft 29 drives the conveyer 3, and as it is important, in view of the timing of the progress of the stream of soil with the tools 15, that the conveyer 3 should not slip, the drum 36A over which it passes at its far end is also driven by a chain 135 which passes round sprockets on the shaft 29 and the shaft of the drum 35A.

Title: Electro magnetic time relay
IPC: H01H71/44
Filed: 1934-01-29
Abstract: 434,275. Electromagnetic switches and automatic circuit-breakers. SCHIELE & BRUCHSALER INDUSTRIEWERKE AKT.- GES., Baden - Baden, Germany, and CRABTREE & CO., Ltd., J. A., Lincoln Works, Walsall. Jan. 29, 1934, No. 2923. Convention date, Jan. 28, 1933. [Class 38 (v)] An automatic switch or circuit-breaker embodies a time device which delays the operation for a predetermined time interval and has an oscillatory body or pendulum which is influenced by a retractive force and which is adapted to perform or initiate a switching-off operation, the oscillatory body being acted upon by an electromagnet which imparts successive impulses to said body until it attains a sufficient amplitude and /or energy of vibration to effect the desired switching operation. As shown in the Figure, the electromagnet 1 is connected between the neutral conductor O of a three-phase supply R, S, T and earth and when the potential exceeds a predetermined magnitude it attracts the spring mounted armature 8 and imparts an impulse to the pivoted balance wheel 5 with retractive spring 6. The movement of the balance wheel breaks the contact of the electromagnet at contacts 3, 4, but this contact is remade when the balance wheel returns under its spring action and if the excessive potential between neutral and earth is maintained another attraction of the armature ensues. Thus a series of increasing oscillations of the balance wheel is set up until finally the contact-carrying projection of the balance wheel engages a tripping lever 14, causing the opening of the circuit breaker. Numerous modifications are described involving balance - wheel and pendulum actions. In some of these the balance wheel may complete at a distance a separate tripping circuit. Alternatively, to ensure correct tripping the tripping action may be arranged to take place on the return movement of the balance wheel or may take place after a pendulum member has by successively increasing vibrations been moved over a dead-centre position. The electromagnet itself may be arranged to produce the tripping action after a connecting member has been displaced by the oscillating balance wheel. Arrangements for adjusting the period of time before tripping takes place are also described.

Filed: 1937-12-29
Abstract: 513,359. Electroplating. NACHTMAN, J. S. Dec. 29, 1937, No. 2983/39. Divided out of 503,475. [Class 41] Plated or coated strip metal stock is passed through a bath of hot liquid to alloy the plating or coating, then without exposure to the atmosphere is passed through a second liquid bath for cooling and brightening the coating, the' transfer being effected below the liquid levels. The baths are preferably hot and cold oil baths, and the stock is preferably transferred by driving means engaging the stock only after its entry into the cool oil bath. The plated or coated strip S passes from the hot oil tank N provided with heating elements 81 through the duct 83 to the cold oil tank O, wherein the oil is circulated between the intake 84 and discharge orifices 85 in a nozzle member 86. The strip is engaged by the driven roller 88, and passes to squeegees C<4> and C<5>. Since the cold oil side of the duct 83 is higher than the hot oil side, a static balance exists between the two baths, and transfer of the oil prevented. In a modification, the two oil baths are separate compartments in the same vessel, a heat-insulating partition being provided. Specification 503,475 is referred to.

Title: Apparatus for measuring and delivering liquids in predetermined quantities
IPC: G01F11/28
Filed: 1928-02-01
Abstract: 302,079. Tella, T. di. Feb. 1, 1928. Fixed-chamber apparatus with counting and registering apparatus.-In visible apparatus for delivering measured quantities of liquid, each successive operation in the cycle is interlocked with the previous and following operations, and is out of control of the operator, who can only deliver the predetermined quantity and must reset the apparatus in its original position before further use. A cam 4 associated with the indicator 10 controls the movement of the overflow pipe 7 through the agency of stops 14-19 associated with a rack 10 operating the pipe 7, and a distributing-drum 27 with cams thereon controls the other parts. A stop 5 moved by a cam 4 according to the movement of the indicator 2 engages one of the stops 14-19, which stops are of different sizes and determine the level the overflow pipe must occupy when the handle 20 is turned clockwise. The handle 20 turns a disc 22 fixed to the shaft 21 and this turns a spring- pressed pinion 24 through friction engagement until the stop 5 is engaged. Further movement of the handle 20 causes the disc 22 to move to the left and with it a bar 26 whereby the stop engaged by stop 5 is locked in position. A hole c in the disc 22 engages a stud 28 on the drum 27 which is then rotated. The drum has cam grooves d, f, a stud g, a cam h at one end, and a ratchet i at the other end. The cam h has a gap with helical ends, engages a recess j in the bar 26, and ensures the locking of the stop and the engagement of the disc 22. The ratchet mechanism ensures rotation in one direction. The cam d controls the cock 34 arranged between the supply pump and the container 50. Liquid in excess of that required is supplied to the container. A device 41, 42 of the kind described in Specification 291,710, operated by a lever 38 on the rod 37 operating the delivery valve 43 prevents the operation of the valve 43 until the excess fluid has run off. When the valve 34 is closed, the cam f actuates the lever 27 on the rod 37. A second cylinder with a spring-pressed piston is arranged in the path of a stud on a lever at the end of the rod. This cylinder is in communication with the chamber 50 and prevents the closing of the valve 43 after it is open until the chamber 50 is emptied. During the rotation of the drum 27 a part of the cam h displaces the part 30 to the right to present an obstacle to the stud g thereby preventing rotation of the drum 27 once the cycle is completed. At the same time the part 26 comes to rest in front of the recess h<1>. The spring 25 then moves the disc 22 and the part 26 to the right and releases the stop. When the rack is lowered to zero delivery, a member 48 engages the member 30 and releases the stud g, and the meter 49 is operated. Specification 274,322 also is referred to.

Abstract: 1,086,794. Fluid-pressure servomotor systems. GENERAL ELECTRIC CO. Jan.26, 1966 [Jan. 27, 1965], No.,3465/66. Heading G3P. [Also in Divisions F1 and F2] Fuel is supplied to a gas turbine 10 via a control unit 16 and line 18, the latter communicating with a by-pass line 28, 30 when a by-pass valve 78 is opened as a result of the engine exceeding a predetermined speed. In the embodiment shown, an engine shaft 42 is connected via a flexible coupling 40 with a hollow spindle 38 having a tube 44 located at one end therein. The free end of the tube carries an unbalanced weight 70 that defines a jet orifice, the latter communicating via the tube 44, bores 66, 62 in shaft 38 and port 58 with a fuel supply line 118. A receiving orifice 98 communicates with a chamber 95 housing by-pass valve 78. At speeds below the predetermined value, the jet orifice communicates with the receiving orifice and generates a pressure in chamber 95 which, with the aid of spring 94, urges valve 78 to the right. As the said speed is exceeded the cantilevered tube 44 deflects and the degree of communication between the jet and receiving orifice is progressively reduced thereby lowering the pressure in chamber 95 and allowing the valve 78 to move to the left under the action of fuel admitted from line 118 and port 88. Leftward movement of valve 78 progressively uncovers triangular-shaped ports 110 to allow fuel to by by-passed to line 30 via port 116. A passage 120 communicates with port 116 and chamber 92 to prevent excessive build-up of pressure in the latter. The receiving orifice is preferably 1À5 to 2 times larger in diameter than the jet orifice. The ratio between spring rate of the cantilevered tube 44 and the weight rate (M#<SP>2</SP>) of the unbalanced mass 70 is preferably between 1À25 and 1À1 to 1À0 at the predetermined speed. The circular mass is rendered unbalanced by drilling a small hole in its periphery Fig. 3 (not shown). In the embodiment of Figs. 5-7 (not shown), the jet orifice (68') is eccentrically disposed in mass (70') and lies radially opposite the position of the centre of gravity of the latter. Valve (78) is urged to the left by spring (130) but is moved to the right when the jet orifice communicates with the receiving orifice (98') as the speed exceeds the predetermined value, thereby by-passing fuel via ports (100, 110 and 116). In Fig. 8, (not shown), the orifice (98") in mass (70") is the receiving orifice and co-operates with a fixed jet orifice (68") to control valve (78) via port (62).
