Patent GB-421314-A (GB)
Title: Improvements in or relating to pressure difference producing devices for fluid flow meters
IPC: G01F1/42
Filed: 1934-04-20
Abstract: 421,314. Flow meters. SANDISON, A. G. S., Kelda., Baltasound, Shetland. April 20, 1934, No. 11918. [Class 69 (i)] A carrier 1, Figs. 2 and 3, foi an orifice disc 3 has an extension 5 with passages 6, fitting into a groove in a block 9 having passages 10 leading to meter pipes 11. The block 9 is secured by nuts 13 or studs 14 carriec by blocks 8 fitted in holes or notches in the sides of the extension. The passages 6 may be drilled, or may be formed by slotting and welding cover plates in the top of the slots. 421,333. Electrically-actuated valves. SATCHWELL, L., Farnham Road, Slough, Buckinghamshire. May 9, 1933, No. 13514. [Class 135] [See also Groups XI and XXXVII] A device for controlling an oil burner comprises an armature 3 pivoted at 3a and moved towards an electromagnet 2 by a cam 12 operated by a lever 11. The armature is held near the electromagnet by friction between the cam 12 and an adjustable inclined plate 13. This movement opens a fuel supply by opening a valve 5 or may close a switch 4 to start a blower or may carry out both these operations to control the supply of fuel. A thermal switch is arranged in the frame or flue and energizes the electromagnet 2 thereby attracting the armature and permitting the cam to fall to its original position. Failure of the flame causes the electromagnet to be de-energized releasing the armature closing down the burner. The thermal switch may be in series with a pressure or thermal switch in the boiler to close down the burner upon excessive temperature or pressure. A switch 15 is operated by a cam 16 on the armature and is in series with the thermal switch so that the electromagnet cannot be energized until the armature 3 is actuated by the cam 12.

Title: Improvements in gas blast electric circuit breakers
IPC: H01H33/16
Filed: 1941-09-18
Abstract: 549,595. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd., and COX, H. E. Sept. 18, 1941, No. 11962. [Class 38 (v)] In a gas-blast switch employing co-operating pneumatically-actuated contacts in extinguishing heads and an auxiliary electrode connected to one of the contacts over a currentreducing resistor as in Specification 530,338, gasconsumption is economized by cutting off the supply of gas to the one contact after the arc thereat is quenched, so that its spring returns the contact and cuts off the escape of gas from the other, which remains held open by the gaspressure supplied to it, reclosure of the other contact occurring when the supply thereto is in turn cut off. In the example shown, both contacts 12, 13 are tubular, the contact 13 being smaller, and the auxiliary contact 23 is spherical and biased by spring 24 against head 2. In opening circuit, both contacts are retracted and 23 is raised clear of head 2. After extinction of the arc, the supply to 12 is cut off and spring 19 thereof causes the contact 23 to be pressed on the nozzle of head 2, whereby during the continued pressure of gas in head 2, contact 13 is held open without loss of gas therefrom. The gas may be admitted to the heads outside the cylinders so that the blast flows round, as well as through, the contacts. In another form, Fig. 4 (not shown), the auxiliary contact is a fixed ring in the nozzle of head 2 and is engaged by the contact 12, escape of gas being prevented by arranging the inlet port to contact 12 so that it is blocked by the enlarged cylinder-head in this position. The Provisional Specification refers also to Specification 483,996.

Patent GB-1348195-A (GB)
Title: Device for feeding platelike articles
IPC: H01M4/20
Filed: 1972-03-15
Abstract: 1348195 Feeding sheets WINKEL MACHINE CO Inc 15 March 1972 [18 March 1971] 12076/72 Heading B8R Battery grid plates 21, Figs. 2 and 4, are stacked vertically by means of lugs 22 on chains 24, 25 of an input conveyer so as to be pressed against surfaces 64, Figs. 4 and 8, of oscillating members 56 actuated by a cam 72 which periodically moves clockwise to the position of Fig. 8 to move a batch of plates away from the rest of the pile and against stop blocks 101, Fig. 6 and 8, adjustable by screws 96. Discs 40, 41 each having four teeth 46 rotate so that when a tooth on each disc rises to the position Fig. 8, it engages the lugs of one or more plates to be separated, the blocks 101 being arranged so that the teeth engage only about half of the thickness of the place or the last plate to be separated. The plate or plates is or are raised by the teeth and when they are moved clear of the blocks 101, adjustable guide rollers 117 push it or them fully on to the teeth, whereupon it or they are carried over the discs and under guide spring plates 127 with the trailing edge or edges running along guide rods 51 to be deposited on an output conveyer 36 to be carried past a processing station 35 or on to a sloping shoot. After a separating operation, the members 56 return to their initial positions. In another form, Fig. 10, the trailing edges of the plates 21 fall from the rods 51 on to a fixed plate 151 and are moved forwardly by oscillating rods 157 actuated by a cam 160, thereby releasing the ears from the teeth 46 while the latter are still above the plate 151. The plates are thus pushed forwardly into engagement with the output conveyer 360 and below pressure rollers 149. In another form, Fig. 16, the discs are each formed with eight teeth 46c, each preceded by a recess 213. A group of plates are advanced by the oscillating members 56c against the stop blocks 236, and the or each plate moved upwardly by the teeth 46c passes into an orifice 266 between elements 264, 265, which by cam actuation after the plate ears 22c have cleared the blocks 236, move forwardly to locate the ears fully into the recesses 213. The output section comprises two pairs of conveyer chains, the outer pair carrying spaced lugs which engage behind the ears after a plate is deposited on the chains so as to move the plate forwards positively. After these lugs have moved downwardly out of the path of the plate as the lugs pass over the front chain sprockets, similar lugs carried on the inner pair of chains engage the trailing edge of the plate and urge it forwards positively into the nip of feed rollers.

It is postulated that the sugars become concentrated in the gel solids relative to the liquid serum under the action of centrifugal force. Fine solids taken up by the extraction water may be returned to the sugarsdepleted gel solids and liquid serum. The liquid serum may also be treated to remove sugars and can be concentrated to improve the efficiency of sugars removal.
