Title: Improvements in siphon-discharge apparatus for liquid containers
IPC: E03D1/14
Filed: 1930-01-30
Abstract: 342,138. Siphon discharge water-waste preventers. MILNES, G. P., Brightlands, Southborough, Tunbridge Wells, Kent. Jan. 30, 1930, No. 3244. [Class 26.] Siphon discharge apparatus for liquid containers of the type in which the liquid is delivered by a siphon set in action by raising a bell over a delivery pipe and then allowing the bell to fall, a valve being arranged on the bell so that air can enter to interrupt the siphon action, is so arranged that one operation of the bell-raising mechanism opens, and two closes the valve, thus two pre-determined quantities of liquid can be delivered at will. The siphon bell 15 has attached to it a hollow cylindrical valve having two sets of holes 20 arranged diametrically opposite each other these holes being covered by a cap 19 having similarly arranged holes 21, a flange 22 being secured to the cap, and having four studs 23 to 26. If the smaller flush is required, one pull is given to the chain 17 which raises the bell 15 and causes a stud 23 to engage the forked end 29 of an arm 28, which turns the cap 19 and causes the holes 20, 21 to register. During the delivery of the flush the lever 12 drops, and with it a lever 32 suspended therefrom, the end of which trips past one of two studs 30, 31 on the flange 22. As soon as the water has fallen to the level of the valve 18, and the float 13 rises again, the lever 32 engages with a stud 30 and turns the cap 19, closing the valve. If the larger flush is desired, two pulls in quick succession open the valve and then close it again by means of the studs and forked lever 28, neither of the studs 30, 31 engaging with the lever 32 to actuate the valve during the replenishing of the cistern. The Provisional Specification describes a pawl and ratchet device for rotating the outer sleeve of the cylindrical valve and resetting means comprising fins on this sleeve with weights which operate to rotate the sleeve when the water level falls.

Filed: 1946-02-04
Abstract: 636,666. Regenerators. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and ALCOCK, J. F. Feb. 4, 1946, No. 3526. [Class 64(i)] In a rotary regenerator, carbonaceous deposit on the rotor is removed by temporarily decreasing its speed of rotation so that its temperature is raised enough for the deposit to be burnt off, one of the fluids taking part in the heat exchange being able to support combustion. In the gas turbine plant shown, the rotor 1 is driven by an electric motor 50 through a variable speed gear 49 operated by a relay 51 actuated by a time switch 52. Altern'atively, the change may be made either manually or by 'automatic means actuated by a revolution counter or by the resistance of the matrix to gas flow. When the speed of rotation is reduced, extra fuel may automatically be supplied to the combustion chamber 42 of the gas turbine 44, to compensate for the reduction in turbine output.

Title: Improvements in or relating to electric signalling systems
Inventor: HARTLEY GEORGE CLIFFORD
IPC: H04Q1/446
Filed: 1947-02-07
Abstract: 654,639. Voice frequency signalling. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1947, No. 3710. [Class 40 (iv)] In an arrangement for converting D.C. impulse trains into V.F. trains each impulse is delayed by a constant amount, thereby providing time for a digital prefix to be sent. Relay A, Fig. 1, operates to the seizing loop and X operates over its right-hand winding during the operate time of B to transmit an X- frequency seizing pulse. In response to impulsing, X operates immediately on the first impulse to transmit an X-frequency signal and holds subsequently over its shunt RS until the end of the train. Relays YA, Y follow the impulses with a constant time lag dependent on the resistance-capacity networks RC1, RC2, each operation of relay Y causing Y-frequency impulses to replace the X-frequency signal. X-frequency is transmitted after the last impulse during the relapse of relay X. On release A falls back and X-frequency is transmitted until Y comes up to give a long Y-frequency pulse during the release time of B which removes the shunt RS so that X releases before Y and no X-frequency signal is sent. Relay RCA provides recall facilities by causing temporary operation of RCB which causes X, YA, Y to transmit an X prefix followed by a short Y pulse, RCA disconnecting RS to prevent a subsequent X pulse being sent. In the receiver, Fig. 2, the seizing pulse operates XX to bring up release relay BB. Relay XY is released by XX during impulsing to block further transmission along the speech wires and to enable at xy2 the Y-frequency receiver allowing relay XY to repeat the impulses over the outgoing loop. A long Y-pulse preceded by, but not followed by an X-pulse releases BB. On a short Y-pulse following an X-pulse, release of XX before YY causes RCC to operate and lock to give a recall signal. The circuit may be modified so that no X tone other than a digital prefix is sent and the total signalling time may be further reduced by causing Y and YA to short-circuit their respective condensers so that these relays have no release delay and the length of the Y pulses is correspondingly reduced. Specification 534,023 is referred to.

Abstract: 942,212. Weighing-apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 17,1962 [Feb. 1,1961], No. 3758/61. Heading G1W. Automatic apparatus for the constant weight feeding of material comprises a weighbeam with a pivotally supported pan, means for pivoting the pan between a charging and a discharging position and signalling means for effecting control of the angular position of the pan and for initiating and/or terminating preceding and/or succeeding materials handling operations. In the form shown, material is fed by a vibratory feeder (not shown) to a weigh pan 4 at one end of a weighbeam (not shown) having a weight at the other end. The pan 4 is mounted on a pivot 6 and connected by a link 30 to an arm 29, movement of which pivots it into discharge position in which the material is tipped into a mixing device (not shown). The arm 29 is operated by a gear 28 engaging a toothed rack 23 mounted between two heads 25a, 25b, slidable in a cylinder 20 closed at both ends. The spaces 32a, 32b between the heads and the ends of the cylinder have parts 33, 41 fitted with non-return valves by which they are connected to pipelines 38, 46. Pairs of ducts 35, 36 and 43, 44 fitted with restrictors connect the spaces 32a, 32b with chambers 37, 45 on the upstream side of the valves 34, 41. The pipelines 38,46 are connected to an air relay cylinder 10 having a pneumatically operated slide 49,parts 51, 53 open to atmosphere,a part 50 connected by a pipeline 59 to a pilot valve 11 and a part 52 connected to an air pressure pipeline 58 also connected to the valve 11. The valve 11 has a slide member 54 operated by a solenoid 12 and a part 57 open to atmosphere. In operation, the vibratory feeder is controlled by a cam operated switch (not shown) and a pair of contacts which are opened on descent of the weighbeam,the descent closing a second pair of contacts to transmit a signal to a main relay panel which in turn transmits a signal to a pulse length relay 13, operating a relay 62 to close contacts 72 shunting a resistance 67 in the circuit to the solenoid 12 thereby operating the valve 11, movement of which causes the relay cylinder 10 to operate whereby air pressure is applied to the head 25a and the space 32b is connected to atmosphere through the ducts 43,44 The consequent movement of the rack 23 tips the pan 4. The contacts 72 having opened,the relay 69 maintains the contacts 68 closed until a condenser 70 across the relay discharges whereupon the solenoid 12 is deenergized and the valve 11 returns under spring action whereby air pressure is applied to the head 25b and moves the rack 23 to return the pan to upright position. Movement of the weighbeam closes the contacts to the vibratory feeder.
