IPC: D06F45/00
Filed: 1922-08-31
Abstract: 205,631. Iveson, J. H. Aug. 31, 1922. Guards.-In wringing and mangling machines, two tiltable frames carry between them a pair of guard rollers, disposed respectively in front of and behind the squeezing-rollers, are supported pivotally on the machine frame by the guard roller axles, and are movable transversely to bring either guard roller into contact with the lower sqeeezing-roller, the axle of the other guard then acting as a fulcrum for the frames. Plates c carry between them guard rollers a, a', the axles m, m<1> of which project through the plates and rest on ledges d formed on the main frames e or on brackets secured thereto. Recesses f, as shown or below the level of the ledges d, are so arranged that one axle m<1> may rest therein and serve as a pivot for the plates c while the other roller a is held by gravity, with or without the assitance of springs g, in frictional contact with the lower squeezing-roller b on the feeding side thereof. Articles are fed beneath the roller a, the axle m<1> being preferably above the nip of the rollers b, b<1>. When the feed is reversed, the plates can be shifted by handles j to bring the rollers a<1> against the roller b, the axle m then serving as a pivot. The space above the rollers a, a' is guarded by boards i carried in lugs of the plateg c. The rollers a, a<1> may be provided' with rubber or like driving-rings h at each end,. and may be covered with rubber; they may be connected by a driving-chain, which may also pass over a sprocket provided on the upper roller b<1> and of equal diameter thereto, in order to ensure that articles coming into contact with the rear guard roller shall pass beneath it. Stopping machinery by movement of guards.- Where the machine is driven by an electromotor, excessive movement of a guard roller may break the supply circuit.

Filed: 1947-08-27
Abstract: 626,435. Electromagnetic relays. WESTERN ELECTRIC CO., Inc. Aug. 27, 1947, No. 23713. Convention 'date, Aug. 28, 1946 [Class 38(v)] The armature 27 of a relay is fixed to an insulating operating member 30 through slots in which pass an upper row of contact springs 16 and a lower row of cooperating contact springs 14. The upper springs 16 take the form of wires to the ends of which are welded flat pieces 20 and when it is desired that energization of the relay should "make" a circuit or circuits the corresponding springs 16 are fixed to the member 30 by being looped over a cross portion 37 of it, Fig. 10. These springs serve to support the armature and when the latter is attracted they move with it to engage their lower contacts 14 which pass through a slot 38 in the member 30 and normally rest against a fixed insulating cross bar 42. The remaining upper springs 16 normally engage their lower springs 14, as shown in Fig. 9, the slots in the member 30 being of suitable form and downward movement of the armature 27 causes a " break." The core 1 of the relay is E-shaped and the coil 6 is wound on the centre leg. The armature 27 extends over all three legs. The lower spring 14 consists each of two wires of different diameter to prevent simultaneous opening of contacts due to similar periods of vibration. A front cover 62 with a window 63 is adapted to be telescoped over a rear cover 55 which supports the cross bar 42.

Title: Improvements in or relating to resinous compositions
Inventor: BARNETT GEORGE
IPC: C08K3/38
Filed: 1948-09-09
Abstract: Powdered resols which may be stored without sintering are produced by incorporating in a resol having a melting-point not greater than 50 DEG  C. a proportion of boric acid.  The incorporation is effected by grinding together the boric acid and the resol, by mixing solutions of the boric acid and the resol and precipitating the resol-boric acid complex, or by milling the boric acid and the resol on warm rolls and then grinding.  The complex formed has a higher melting-point than the resol itself, and may be used in the production of moulding powders or adhesives.  Ortho-, meta- or pyroboric acid may be employed.  In examples: (1) a resol obtained by refluxing for 2 hours 100 parts phenol and 120 parts 37 per cent formaldehyde in the presence of 0.36 parts NaOH and 2.7 parts ammonia, neutralizing with phosphoric acid, and distilling off water under reduced pressure to give a brittle resin melting at 45 DEG  C., was ground to powder and mixed with amounts of boric acid of from 0.5 to 10 per cent. The mixtures had melting-points up to 98 DEG  C.; (2) a resol obtained similarly from mixed xylenols had a melting-point of 48 DEG  C. which rose to 70 DEG  C. on mixing with 5 per cent boric acid; (3) 100 parts of the resol obtained in example (1) was dissolved in industrial alcohol and 4 parts boric acid dissolved in 40 parts alcohol were added.  A white precipitate was obtained which was ground to a powder.

Title: Improvements in or relating to electric circuits employing gas-filled discharge devices
IPC: H01J17/04
Filed: 1934-08-20
Abstract: 442,747. Converting. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and DUNHAM, C. R., c/o General Electric Co., Ltd., Wembley, Middlesex. Aug. 20, 1934, No. 23973. [Class 38 (ii)] [See also Group XL] In an arrangement employing a discharge device and in which the anode potential during conduction of the device remains substantially constant, to effect extinction of the device a momentary impulse of negative potential is suddenly applied to the control grid. During the period when the valve 1, Fig. 1, is conducting due to a positive impulse applied to the grid from a source not shown, the condenser 11 is charging substantially to the line potential. To effect extinction the switch 12 is closed, the charged condenser being thereby connected between the grid and cathode of the valve to apply a large negative bias to the grid. In a modification of this, the switch 12 is replaced by a grid-controlled valve. Fig. 3 shows an inverter in which the negative extinguishing bias for the grids is obtained from condensers 28, 29 cross-connected between the anodes and grids of the discharge devices 21, 22, the grids being connected to the cathodes through resistances and a grid bias battery. Here the negative bias is applied (e.g.) to the grid of valve 21 from the condenser 29 when the valve 22 conducts.
