Title: Improvements in or relating to liquid dispensing apparatus
Inventor: SPALDING ROBERT GEORGE
IPC: B67D7/08
Filed: 1953-06-29
Abstract: 740,645. Counting-apparatus. WAYNE TANK & PUMP CO., Ltd. June 21, 1954 [June 29, 1953], No. 17942/53. Class 106 (1). [Also in Group XVIII] The counting and indicating mechanism of a liquid dispensing apparatus is zeroized by forward rotation of the zeroizing shaft, the indicating drums being covered by shutters during such rotation and the said shutters being released to return to their normal positions when the drums reach zero. The zeroizing shaft is rotated by the pump driving motor through a mechanical connection including a unidirectional clutch. The pump motor 1, Fig. 2 (not shown) drives a flanged disc 11, Fig. 5, through a belt, a pulley 6 and a worm and worm wheel. The flanged disc 11 is notched at 15 to co-operate with a pawl 18 pivoted on a crank 17 freely mounted on the spindle 12 of the disc 11. A trip lever 24 is also pivoted to the crank 17. The pawl 18 and the trip lever 24 are urged clockwise, Fig. 5, by springs 21, 27 respectively. Upon movement of a lever 4 to the position shown in Fig. 5 a switch in the pump motor circuit is closed and the motor drives the disc 11. The spring 21 pulls the pawl 18 into the first notch 15 so that the crank 17 is rotated for a complete revolution until a lug 29 of the trip lever 24 meets the lever 4 whereupon the step 26 of the lever 24 meets the end 20 of the pawl 18 and withdraws it from the notch 15. The rotation of the crank 17 is transmitted via link 31, Fig. 1, crank 32 to effect rocking of a quadrant 34 which is connected through a gear 35, Fig. 3, a unidirectional clutch 36, 37, a frictional clutch 39 and a shaft 40 to the zeroizing shaft of the counter. During the forward movement of the quadrant 34 the zeroizing shaft is rotated forwardly through 405 degrees to effect zeroizing of the drums and on the reverse movement of the quadrant when no movement is imparted to the shaft 40 the zeroizing shaft is rotated back through 45 degrees by springs. When at the end of the dispensing operation the lever 4 is moved to switch off the motor the lug 29 of the trip lever 24 is freed but a second lug 25 thereon is obstructed by the lever 4 to prevent effective movement of the crank 17.

Title: Process for the separation of sulphur from gases obtained in the roasting and smelting of sulphur bearing ores
IPC: C01B17/027
Filed: 1919-07-22
Abstract: 152,447. Collins, C. G. July 22, 1919. Sulphur.-To recover sulphur from the gases obtained in the roasting and smelting of sulphurbearing ores, the gases in a dry state are passed into a cooling-chamber maintained at a temperature slightly above the condensation point of sulphur, and then into a condensing-chamber at a lower temperature, the sulphur depositing on collecting-material in this chamber. The temperature of the cooling-chamber is controlled by varying the speed of the gases. Thus, the gases from a furnace or retort 1 are withdrawn by means of a fan 4 or other equivalent device, the speed of which can be adjusted, and are then passed into a metal cooling-chamber 3, and the cooler gases at a temperature just above the condensation point of sulphur are passed through a pipe 5 into the depositing chamber 6; in this chamber the sulphur deposits in screens 7, 7<1>, those near the inlet being conveniently of asbestos and the later of excelsior; the screens 7, 7<1> are removably supported in frames 9, and are reciprocated by the mechanism shown to remove the sulphur collected thereon. It is important that the gases should be rapidly withdrawn from the furnace 1, (to permit this the flue 2 is of large diameter), and that the cooling-chamber 3 should be located as near the furnace as possible. Reference has been directed by the Comptroller to Specifications 1974/81 and 6567/92.

Title: Improvements in electrical energy regulators for electric cookers, ovens, hot-plates and the like
IPC: F24C15/10
Filed: 1944-09-26
Abstract: 587,953. Switching systems for heating resistances. SHARPLES, J. T., WOOLNOUGH, G. L., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 26, 1944, Nos. 18371/44. 4048/46 (divided out of 587,947, [Group XXXVII]) and 11497/45. [Class 38 (iv)] In a supply system for a hot-plate or the like having two or more heating elements controlled by a regulator which adjusts the average current input to the elements by adjustment of the " on " and " off " periods of the current, the regulator has, in addition to a number of control settings in which the elements are connected in parallel and which proyide progressively increasing mean current input, further settings whereby the circuit of one element may be interrupted or the circuits of all the elements may be continuously closed. The regulator may be of the form described in Specifications 517,538 or 587,947, [both in Group XXXVII]. As shown, heating elements H1, H2 are supplied from lines LI, L2 through a regulator of the form illustrated in Fig. 9 of Specification 587,947 and having six control settings in addition to an " off " position. In the " off " position, contacts 5, 6 are maintained separated to open the common supply lead from line L1, whilst over the range of control settings 0-4 the elements are energized in parallel over the normally closed contacts 50, 51 of a snap action switch and the intermittently closing contacts 5, 6 of the regulator. The period of closure of the latter contacts progressively increases from setting " 0 " to setting " 4." At setting " 4.5 "contacts 5, 6 are permanently closed and the elements, therefore, continuously energized, whilst at setting " 5 " the snap action switch opens its contacts 50, 51 so that element H1 alone is energized continuously. In a modification, contacts 50, 51 open at setting " 4.5 " and reclose at " 5."

Abstract: 1457190 Temperature-responsive actuating elements TEXAS INSTRUMENTS Inc 29 April 1974 [30 April 1973] 18671/74 Heading G1D [Also in Divisions F1 and H1] A stepping drive (for a time switch in household appliances, for example) comprises ratchet means, pawl means movable for advancing said ratchet means, spring means biasing the pawl in one direction, actuator means of a selected metal alloy arranged to be deformed as said pawl is moved by said spring bias while said alloy displays a relatively low modulus of elasticity due to it being below a transition temperature and to abruptly return to its original configuration by displaying a relatively high modulus of elasticity, thereby moving said pawl in an opposite direction against said spring bias to advance said ratchet means, when said alloy is heated above said transition temperature, and means for intermittently heating said actuator means above said transition temperature. As shown, the actuator is a wire 40 of 55% nickel 45% titanium, which is said to have a four-times increase in its modulus of elasticity when heated above about 60C. It has a diameter of 0À002 inches or less and is stressed by a blade spring 46 carrying a contact 48 normally engaging a contact 50 such that a current may flow between terminals 54, 56 to heat the actuator 40, which is preferably in series with a resistor 42. This causes the actuator to contract and open contacts 48, 50 whereupon it cools and allows expansion. A pawl 58 is thus oscillated as indicated by arrow 59, and drives ratchet means, which may be linear but as shown is a wheel 38, coupled to shaft 14 which carries cams 18, 20 acting on respective contact sets 22, 24. Alternatively shaft 14 may drive a drum with appropriate sliding contacts. Since a change in ambient temperature has opposite effects on heating and cooling of actuator 40 the rate of operation of shaft 14 is not altered thereby.

Title: A coincident-current switching core matrix
IPC: G11C7/02
Filed: 1959-06-02
Abstract: 900,780. Circuits employing bi-stable magnetic elements. TELEFUNKEN G.m.b.H. June 2, 1959 [July 3, 1958], No. 18795/59. Class 40 (9). Inductive output circuits, particularly the row and column wires of a storage matrix, are selectively energized by a positive, followed by a negative pulse which pulses are generated by switching a pair of cores associated with each output circuit, first and second cores of each pair being connected in first and second matrices, respectively, such that coincident energization of row and column wires of the first and second matrices produce the positive and negative pulse, respectively. The first and second matrices may have common row wires and their cores are biased into saturation. As shown in Fig. 3, two m X n matrices may be driven to selectively provide output in m X n output circuits. Corresponding cores in each matrix are linked by the windings such as W<SP>I</SP>, W<SP>II</SP>, connected in series with an inductive load L, as shown in Fig. 2a. By operation of one each of the row and column switches S z1  to S zm  and S S1  to S Sn,  and by selection of the first matrix by switch S<SP>I</SP>, the cores of the selected row and column are withdrawn from saturation under bias and the coincidently energized core at their intersection is turned over to provide a positive output pulse in winding W<SP>I</SP>. Disconnection of switch S<SP>I</SP> coincident with connection of switch S<SP>II</SP> to connect up the second matrix causes the corresponding core in the second matrix to be turned over to provide a negative output pulse in winding W<SP>II</SP>. To obtain equal value positive and negative pulses it is shown that the cores of the second matrix can be made smaller than those of the first. In the arrangement of Fig. 4a the matrices have common row wires and column wires threaded with both matrices such that energization of a column wire acts to switch one matrix but augments bias in the other matrix. Thus the equal and opposite shifts of flux in the saturation region suffered by each pair of cores of a column are additive in the output circuit and to cancel these unwanted pulses all the output circuits of each column are connected in parallel and placed in series with an inductor, Fig. 5, not shown, such that current through the selected energized load produces a voltage across the inductor to balance the unwanted voltages in the other load circuits. Unwanted pulses do not occur in the rows as energization of a row wire moves both cores of each pair from saturation to remanence in the same direction which induce opposite voltages in the load circuit.
