Title: Improvements in and relating to electric relays
IPC: H01H50/46
Filed: 1945-05-10
Abstract: 591,480. Electromagnetic relays. BRITISH THOMSON-HOUSTON CO., Ltd. May 10, 1945, No. 11728. Convention date, May 10, 1944. [Class 38(v)] An electromagnetic relay has a U-shaped core which is enclose( throughout its lengtl in a sleeve of copper or other non-magnetic conducting materia in order to delay the flux decay when the energizing current ceases. The core is made by first placing a copper sleeve over a straight iron bar and bending the two together. When the bar is circular its diameter may be 0.6 of the external diameter of the sleeve. Fig. 1 shows a relay having a U-shaped core 2 covered throughout its length with a copper sleeve 3. Windings 19, 20 on the limbs of the core may be wound in the same or opposite directions. A pole piece 2a is attached by a bolt 4 to one end of the core and a rocking armature 5 is pivoted at 6 and carries a pair of contacts 13 which co-operate with two fixed contacts 11. The gap between the armature and core poles can be adjusted by a bolt 18 and the armature is biased away from the pole pieces by a spring 14 adjustable by a bolt 15. A brass or other non-magnetic shim may be introduced between the pole piece 2a and the adjacent end of the core to reduce the residual flux in the magnetic circuit and so permit armature drop-out at a low flux value.

Title: Pumping apparatus for oil wells
IPC: F04B47/12
Filed: 1965-03-19
Abstract: 1,070,344. Reciprocating pumps. DEPUTY MINISTER OF THE MINISTERUL INDUSTRIEI PETROLULUI SI CHIMIEI. March 19, 1965 [March 21, 1964], No. 11766/65. Heading F1A. [Also in Divisions H2 and H3] A deep well pump comprises two buckets or pistons 22, 22' working in pumping chambers P, P', and actuated at the beginning of each stroke by the delivery column pressure, and during the rest of the stroke by a linear electric motor operating at a constant speed (see Division H2). In operation, towards the end of the downward stroke under electric drive, the electric current is cut-off and the piston movement checked by the delivery column pressure and by buffer springs. At the end of the downward stroke, piston 22' uncovers a port 20' communicating with well pressure and a cam member 23 on piston 22 holds delivery valve 18 open, so that the delivery column pressure acts on piston 22 to move the piston assembly upwards until the electric drive is switched on again, piston 22' then performing a discharge stroke, and piston 22 a suction stroke. Towards the end of the upward stroke the electric drive is switched off, and piston 22 uncovers port 20 and cam 23' on piston 22' keeps delivery valve 18' open, so that the delivery column acts on piston 22' to start the downward stroke. If the electric drive fails or is cut off part-way through a stroke, a relay 30 operates valve 29 to connect the pump discharge to the well, so that the piston assembly moves under gravity to its lowermost position, an abutment 33 on piston rod 21 then returning valve 29 to its former position. The pump is then ready to start under hydraulic drive, abutment 33 being locked by relay 30 until the electric current is re-established. Alternatively, non-return valves controlled by a relay may be used in place of valve 29. The electric motor may be asynchronous or synchronous and single phase or multi-phase. The electric motor windings may be cooled by the pumped liquid or by a circulated coolant. The pump pistons may be positioned above or below the electric motor or one at each end Fig. 1 (not shown). The inlet and outlet valves 19, 19' and 18, 18' may be mounted between the pistons Fig. 5 (b), (not shown), so that only packings 24 and 25 need be high-pressure resisting. An electric motor control circuit is described, (see Division H3). The hydraulic drive may be augmented by springs.

Filed: 1961-03-30
Abstract: 923,323. Coffee-machines. HGZ-A.G. March 30, 1961 [April 11, 1960], No. 11790/61. Class 129. A fitting for an espresso coffee machine comprises a cock controlling the hot water supply and a ventilating cock which controls a pipe leading into the filter arrangement, the two cocks being constrainedly connected together so that the ventilating cook is not opened until the hot water cock has been closed and vice versa. In operation, when handle 11 is moved from position A to B (Fig. 2), hot water flows through ducts 4, 15 and 16 and simultaneously through pipes 18 and 28 (Fig. 1) and the expansion tube 13 is expanded by water pressure and forces the closure member 14 to seal off pipe 23. The water passes through pipe 16 into the known coffee filter arrangement. On moving handle 11 back to position A, the hot water feed is interrupted. The presure in expansion tube 13 decreases causing it to contract, drawing closure member 14 against stub pipe 28. This allows a passage from the filter chamber via ducts 23 and 24 to discharge pipe 25 which is positioned over a drip pan. Thus ventilation takes place and excess pressure is relieved.
