Title: Improvements in or relating to transformer and choke assemblies
IPC: H01F38/10
Filed: 1952-10-31
Abstract: 733,194. Transformers with inductors. GENERAL ELECTRIC CO., Ltd., FISHER, F. J., and PARK, K. J. Oct. 27, 1953 [Oct. 31, 1952], No. 27476/52. Class 38 (2). A choke and transformer for use with hot cathode low pressure fluorescent lamps is formed as a composite unit having a single laminated magnetic core, the stacks of laminations forming the core being welded together at one or more places. The core comprises two stacks 1, 2 of E-shaped laminations, the stack 2 having shunt parts 3, 4 which project towards the centre limb but which are not integral therewith. The transformer windings 9 are located on the stack 2 between the shunt parts 3, 4 and the yoke of the E-shaped laminations whilst the choke winding 8 is situated on the stack 1, the two stacks then being placed end-to-end so as to have an air gap 5 between the central limbs and finally welding the stacks together at 6, 7. The central limb of the stack 2 may be split from the core along the dotted line A, in which case the shunts 3, 4 may be affixed to the central limb. The shunts may also be comprised of blocks of compressed magnetic powdered material and may be forced into position after the stacks 1, 2 have been assembled. In an alternative construction the stack 2 may be split on a line passing through the transformer winding, the necessary welds to assemble the third stack of laminations being made only on the two outer limbs.

Title: Improvements in and relating to protective devices for alternating current electric distribution systems
IPC: H02H3/30
Filed: 1920-09-28
Abstract: 173,316. British Thomson - Houston Co., Ltd., and Wedmore, E. B. Sept. 28, 1920. Protective arrangements of the Merz-Price type, and particularly of the form described in Specification 141,121 in which balancing devices relatively sensitive on faults to earth are combined with balancing devices relatively insensitive to faults between phases are provided with a device inductively connected to the feeder circuit and operating to prevent the action of the relay on the flow of excessive current such as might result in the event of simultaneous faults to earth occurring in different phases of different sections of a power distributor system. A transformer may be arranged to surround each of the three main conductors at each end and the secondary windings connected through a device on the relay which trips the oil switches so that, on the passage of a current greater than that which would occur on a normal fault to earth, the relay is held out of action and the oil switches are unaffected. The secondary windings may be connected to the coil of a re-setting device having a plunger which, when raised, engages a falling weight which is checked before it short-circuits the contacts of the trip-coil and may, subsequently, be returned to its set position. The relay device may be arranged with special contacts to short-circuit or earth the pilot cable on abnormal fault conditions.

A rotating drum filter 1, having the usual suction arrangements, has a layer of cloth 2 on which is deposited a layer 3 of filter and such as infusorial earth. The filter aid in the trough 4 is replaced by the liquid to be filtered. The trough 4 is connected by a conduit 7 and pump 7<SP>1</SP> to a spray or trough 20 which itself is connected back to the trough 4. As the drum rotates liquid to be filtered is-sprayed onto the drum at 20 so that filtration takes place over both of the sectors III 1 , III 2 . The last trace of filtrate is removed over sector IV and the residue is washed over sector V by a spray 27. The residue is removed over sector VI together with part of the layer 3 by a rotating scraper 8 having blades 9, and passes down a ramp 24 to an Archemedian screw 26. Over the sector I further filter aid is sprayed, by an atomiser device 15, and this is dried over sector II. The rotating scraper may be moved radially relative to the drum 1. The filter aid supplied through the atomiser 15 and the washing solvent supplied by spray 27 are kept in continuous circulation in a similar manner to the liquid in trough 4, by suitable pumps and tanks for the liquids, to prevent clogging of the spray holes. An agitator 22 is provided and the trough 4 is preferably of the double walled type so that steam may be supplied through conduit 5 to keep the liquid in the trough at the desired temperature. The atomiser device 15 is preferably formed by two relatively rotatable tubes provided with radial ports.

Title: Improvements in or relating to wireless receivers or transmitters and the like
IPC: H03J1/18
Filed: 1937-10-18
Abstract: 505,896. Adjusting wireless apparatus. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Oct. 18, 1937, No. 28298. Convention date, Oct. 16, 1936. [Class 37] [Also in Group XL] The tuning knob of a wireless receiver or transmitter actuates in one position a switching arrangement controlling forward or reverse rotation of an electric motor which drives the tuning element, while in another position the knob actuates the same tuning element over a coupling which is inoperative when the motor is operative. The knob E normally operates the shaft C of the tuning element through friction discs R1, R2 held in engagement by spring D. When E is pushed inwards, R1 rotates a spring contact finger F over a series of contacts K1, K2, K3, Fig. 2, to energize motor M for forward or reverse running. In a modification, Figs. 3 and 4 (not shown), the tuning knob drive remains engaged with the tuning element shaft; rotation of the knob to two extreme positions in either direction closes the motor circuit for forward or reverse running. The tuning knob drive may then be disconnected automatically by a device actuated by the motor current. The motor switch contacts may be arranged to give several running speeds for the motor in each direction and operation of the motor switch may mute the receiver during tuning. A switch may be provided on the spindle of the tuning element which opens the motor circuit automatically when the element reaches either end of its travel, thus preventing a heavy overload on the motor. Specification 469,077, [Group XL], is referred to.

Abstract: 815,004. Recording apparatus. CAMBRIDGE INSTRUMENT CO. Ltd. Sept. 18, 1957 [Sept. 18, 1956], No. 28467/56. Class 106 (4). An electrical recording system comprises uniselector switches with a plurality of positions for selectively connecting the recorder to a plurality of thermocouples to be monitored and, while the pen is moving over the chart to and/or from a position corresponding to the potential of a selected thermocouple, a relative displacement between the pen and the chart is applied in a direction at right angles to the valuerecording movement at an instant determined by the position of the switches to provide an identification portion of the pen trace whose location thus serves to identify the thermocouple selected. 99 thermocouples can be successively or selectively coupled to a selfbalancing potentiometer recorder by means of a " units " and a " tens " uniselector, Fig. 2, which, in co-operation with ten micro switches m0, m1, m2, m3 ... cause energization of a chart drive solenoid to identify the tens figure on the outward movement of the pen and the units figure on the return movement, the micro switches being cam actuated in succession both on the outward and return movements. In another embodiment, Fig. 4, as the pen 11 traces a line 12a to record a value, a brush 13 moves forward and back over nine contacts 14 connected to the nine digits of both the units and tens uniselectors. On the forward movement of the pen 11 and brush 13, a tens solenoid 4 rocks the pen to cause a deviation in a position corresponding to the tens figure of the thermocouple selected and, on the backward movement, when a timing circuit has changed back a switch x-b, a units solenoid 5 rocks the pen to cause a deviation on the other side of the trace in a position corresponding to the units figure.
