Title: Improvements in or relating to transformers
IPC: H01F27/32
Filed: 1958-07-04
Abstract: 842,808. Transformers. WESTINGHOUSE ELECTRIC CORPORATION. July 4, 1958 [July 16, 1957], No. 21464/58. Class 38 (2). In a high-voltage power transformer comprising several spirally-wound coils mounted on a core 13, each coil comprising a plurality of layers, 21, of spirally wound conductors, the layers are separated by spacers 24, mounted on a sheet, 23, of cellulosic insulating material so as to allow the free flow of a coolant. The coils are enclosed in solid insulation having openings 25, 26, for entrance and exit of the coolant, located so far as is possible from the next coil, the core and the case. As the voltage between the layers 21 is not large the coolant acts as the insulation to a great extent, while insulation between coils and high and low voltage provided by solid cellulosic material 30 and 27 respectively.

Title: Improvements in or relating to annealing ovens
IPC: C21D9/00
Filed: 1958-07-04
Abstract: 888,776. Annealing. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 4, 1958 [July 9, 1957], No. 21496/58. Class 72. [Also in Groups XI and XII] An annealing oven comprises annealing and cooling chambers which are arranged to register successively with a delivery device and means for causing the workpieces to travel through the chambers in successive steps. As shown, workpieces are delivered from a furnace 5 through a shoot 4 to one of a series of channels 3 arranged in a drum and moved step by step to register with the shoot 4. A ram 7 moves the workpiece into the channel and at the same time forces a workpiece out of the channel on to a discharge shoot 8. Each channel has a heating section 3a and a cooling section 3b. In normal use the heat in the workpieces is sufficient to maintain the temperature in the section 3a but in starting from cold electric induction or resistance heating may be used. Cold air may be circulated round the cooling section 3b.

Title: Improvements in tinning processes for copper wire
IPC: C23C2/02
Filed: 1934-07-23
Abstract: A bright tin coating is produced on copper wire by applying alcohol to the wire, passing it through a furnace in which it is heated to annealing temperature, and then, without allowing it to come into contact with the air, passing it through a bath of molten tin and then through a wiper.  The alcohol is preferably applied by drawing the wire through a felt pad saturated with alcohol.  The oxides on the wire are removed by the action of the alcohol vapour in the annealing furnace.  The tinned wire can be insulated with rubber for use in the electrical art.

Filed: 1938-07-21
Abstract: 517,180. Volume control. STANDARDTELEPHONES & CABLES, Ltd., and MEERS, R. A. July 21, 1938, No. 21670. Addition to 503,083. [Class 40 (iv)] [Also in Group XL] In an amplifier in which volume expansion is effected by a metal rectifier network in a negative feedback path, the rectifier having a control voltage applied to it dependent on signal level, resistances are connected in series and in shunt with the rectifier to limit the extreme impedance values of the combination in the feedback path. The Figure shows an amplifier with a variable impedance X1 in shunt to the feedback path. The control voltage is derived from the amplifier input after amplification by an auxiliary amplifier V2 the gain of which is controlled by resistance PI associated with the feedback path of the amplifier V2 as described in Specification 513,416. The amplified voltage is applied through a rectifier X2 and time delay circuit L3, C1, C2 to the rectifier X1. The arrangement is such that the voltage across the rectifier X1 is other than zero at the mean signal amplitude level and increases, to decrease the feedback, as the signal level rises. Specifications 475,310 and 479;388 are referred to.

Title: Improvements in and relating to dough handling machines
IPC: A21C5/08
Filed: 1949-08-22
Abstract: 670,370. Machinery guards. RUBERY, J. M., HOY, F., and HAMMOND ENGINEERING CO., Ltd. Aug. 18, 1950 [Aug. 22, 1949], No. 21739/49. Class 80 (iv). [Also in Group V] A guard for a dough handling machine (see Group V) covers the opening between the bed and platen completely and co-operates with means that will interrupt the transmission of movement to the machine from the prime mover when the guard is moved to uncover the opening but before the opening is uncovered. The guard b<SP>1</SP> may swing on a hinge with a vertical pivot pin, as shown at e, or on a hinge with a horizontal pivot pin, or it may slide vertically in guides. As the hinged guard moves into position to cover the opening a projection f on it rides along a ramp i on the end of a plunger h and depresses the plunger, so closing a switch. g in series with the solenoid of the motor starter. One end of the cam f is bevelled at f<SP>1</SP> to fit in a notch n in the plunger h to give a latching effect. A hood l prevents the switch g from being closed inadvertently. A thimble k on the plunger acts as a cover to prevent the admission of dough or other matter. When the guard is mounted on horizontal hinges the hood l curves upwards to allow for the upward swing of the projection f. When the guard slides vertically a downward projection from it enters a deep opening above the switch g and depresses the plunger, there being no ramp or hood in this arrangement, and the guard may be held in its raised position by a spring-pressed ball or a pawl. A weight and pulley counterbalance may be provided for a guard where suitable. Instead of the switch being in a motor circuit it may be in the circuit of a magnetic clutch, or it may be replaced by a lever which operates a friction clutch or an element which, when displaced, interrupts the clutch operating mechanism.
