Title: Improvements in the manufacture and production of sound record carriers
IPC: C09D5/23
Filed: 1935-11-18
Abstract: A sound-record carrier for the electro-magnetic recording and reproduction of sound by magnetic action on magnetizable bodies, according to the known process suggested by Poulsen, consists of a powdery magnetic metal oxide in a finely divided state on or in a non-magnetic carrier material.  The oxides Fe3O4 and g --Fe2O3 are especially suitable, and may be prepared by the decomposition of complex metal salts, for example iron-ammonium salts, or complex organic metal compounds such as pyridine compounds.  The decomposition may be carried out in the non-magnetic carrier material before or after the casting of the mass into a film.  In one example, colloidal g --Fe2O3.H2O is precipitated by blowing air into an aqueous solution of tetrapyridine ferrous chloride, decanted, filtered, heated to 150 DEG  C., in a current of dry air, made into a paste with a solution of acetyl cellulose in acetone, and the emulsion applied to a film of acetyl cellulose by means of a film-casting machine.  Four other examples are described.

A forced circulation monotube boiler, shown diagrammatically in section in Fig. 3, has an upright gas pass 2 leading upwardly from one end of an horizontally-extending combustion chamber 1 provided at its other end with an opening 6 for firing means 7, the boiler tube serving both to form a convection heatexchange section 50 in the gas pass 2 and a lining for the combustion chamber and providing connections for the working medium from and to a separator vessel 41 which is disposed in the recess defined between the combustion chamber and the upright gas pass. Water is drawn from the separator vessel 41 by a circulating pump 59 and supplied to a vertical conduit 55 disposed centrally in the upright gas pass and connected to its upper end to the innermost of five concentric coils which together form the convection heatexchange section. Water flows alternately downwardly and upwardly through these coils in series, the outermost coil being connected to two platen coils in series which line the floor of the combustion chamber. Substantially horizontal tube lengths connected in series line the side walls, one end wall 3 and the roof 10 of the combustion chamber, water flowing through these tubes in a generally upward direction. Steam and water leave the boiler by a pipe 38 which passes through the wall of the separator vessel 41 to an internal cyclone separator, steam being taken off through a duct at the top of this vessel. Feedwater is supplied from a reservoir 80 by a pump 81 and a line 82 into the separator vessel. The walls of the combustion chamber are of the doubleskin type and are partitioned so that air supplied by a fan 11 flows as indicated by arrows 12, 13 and 14 around the gas pass and combustion chamber to an air space 8 from which space it is available for combustion in the nozzle 6.

Title: Method and machine for making bearings
IPC: B21D53/10
Filed: 1966-07-19
Abstract: 1,128,007. Making bearings ; angular bending; shearing. C. S. WHITE. 19 July, 1966 [19 July, 1965], No. 32300/66. Headings B3A, B3E and B3W. In a method of making a bearing, a blank is cut from strip with a notch at one end and a tab at the other, the centre section is then formed around a mandrel to arcuate shape, the ends are formed in succession around the mandrel to arcuate shape and the tab engages in the notch to form locking means. The strip 58 is fed into support means 56 and a punch 26 on an upper die forming assembly 22 cuts a notch 70 in the strip, which is then advanced until its leading edge abuts an adjustable stop 62. As the assembly 22 is again lowered, the punch 26 severs a blank from the strip forming a tab 74 thereon as it does so and a forming surface 24 wraps the blank about the mandrel 20 to a U- shape. Further movement of the assembly 22 drives down the mandrel with the blank and the ends 68, 74 thereof contact forming surfaces 34, 46 respectively to bend the ends inwardly. The end 68 is bent around the mandrel 20 in co-operation with a first lower forming die 30 which is at a higher level than a second die 42. The assembly 22 is lowered still further, thereby forcing down the die 30, forming the end 74 in the second die 42 and engaging the tab 74 in the notch 70. The assembly 22 is then raised, the mandrel 20 indexed axially and the process repeated so that a plurality of bearing elements (78) are formed thereon, Fig. 11 (not shown). The outer surfaces of the elements 78, while still on the mandrel, are centerless ground or otherwise machined concentric therewith. The inner surfaces of the bearing elements may be coated with a low friction organic polymeric material 80, e.g. Teflon (Trade Mark), which may be applied to the strip 58. The material is bonded by a phenolic resin which is partly cured before the forming operations are carried out and the final curing is effected while the bearing elements are on the mandrel. A spherical bearing element may be formed by shaping the blanks around spherical balls spaced on the mandrel.

Title: Improvements in operating mechanism for an electric circuit breaker
IPC: H01H71/56
Filed: 1957-10-17
Abstract: 819,697. Automatic circuit breakers. GENERAL ELECTRIC CO. Oct. 17, 1957 [Oct. 18, 1956], No. 32463/57. Class 38 (5). A circuit-breaker operating mechanism has an over-centre closing and opening spring 50, one end of which is attached to the centre pin 23 of links 21, 22, and the other to a pin 51 on the operating member 52 pivoted to the frame 31 at 53. The link 21 is connected to the contact arm 12 and the link 22 has an end pin 26 movable in a slot 28 in the frame 31. As shown in Fig. 1 a prop 36 is biased by a spring 38 to hold a latch 32 so that it retains the pin 26 at the bottom of the slot 28, and the spring 50 biases the link 22 against a stop 55 on the member 52, to hold the contacts closed, and also biases the member 52 against a fixed stop 29. Energization of a trip coil 43 or manual operation of a push button 42 removes the prop 36 so that the force of the biasing spring 50 and the contact throwoff forces cause the pin 26 to push aside the latch 32 and move up the slot 28 until the pin 26 has passed across the axis of the spring 50 and reached the end of the slot 28. The link 22 then pivots about the pin 26 until the spring axis has passed the pivot 53 so that the member 52 rotates away from the stop 29 and its cam face 60 engages the pin 26 and moves it down the slot 28 so that the latch 32 can reset, Fig. 4. To close the breaker a handle 68 is turned so that a roller 71 lifts the pin 51 to change the spring and move its axis above the pin 26, when it rotates the link 22 to the Fig. 1 position and during this movement the axis also passes the pivot 53 so that the member 52 is also restored to its Fig. 1 position. The mechanism is " trip free " since even if the handle 68 is held the contacts can reach the fully-open state.
