Title: Improvements in or relating to automatically controlled electrical pumping units
IPC: F04D15/02
Filed: 1946-08-19
Abstract: 626,068. Automatic liquid - level control systems ; electric motors. GOODMAN, H. Aug. 19, 1946, No. 24650. [Classes 35 and 38 (iv)] [Also in Group XXVI] A submersible electric pump installed in a sump pit is automatically energized when liquid in the sump rises and bridges a pair of control electrodes, the liquid being maintained in contact with the electrodes until the sump has been substantially emptied. A centrifugal pump 23 (see Group XXVI), is coupled to an electric motor 42 which is enclosed within a hermetically-sealed housing 40 partially filled with oil. Two electrodes 50, 51, pass through insulated sealing bushes, Fig. 2 (not shown), in the wall of the housing 40 and are enclosed by a hollow shield 56 which has a large aperture 58 at the upper end, but only a small aperture 57 at the lower end so that the rise and fall of liquid within the shield is retarded ; hence electrodes 50, 51, are not bridged until the sump is practically filled; and contact is maintained until the sump is substantially emptied. Bridging the electrodes 50, 51, either closes a relay, Fig. 4 (not shown), which energizes the pump motor, or the electrodes may be in series with the motor, Fig. 5 (not shown).

Abstract: 681,949. Toggle fastenings. K.A.C., Ltd. Oct. 9, 1951 [Oct. 11, 1950], No. 24850/50. Addition to 644,699. Class 44. In a toggle fastener of the kind described in the parent Specification, comprising a locking lever 21, Figs. 2 and 3, and a latch lever 31, throw-out means are provided, operated by the latch lever when actuated to release the locking lever, which effect initial movement of the operating end 25 of the locking lever to facilitate manipulation of the latter. In the form shown in Figs. 2 and 3, the construction is similar to that described in the parent Specification, but a throw-out element 38 is provided comprising a pair of bell-crank levers 39 secured to a sleeve 29<SP>1</SP> which is mounted on the pin 29 on the frame 3. The latch lever 31 is cut away at each side to leave shoulders 43 which on pressing in the latch lever as shown in Fig. 3 rotate the throw-out element so that the lower end thereof bears on the locking lever 21 and pushes it forward. In one method of locking the adjustable two-part link 14 of the toggle, the screwed spigot 19, Fig. 4, has a flat which co-operates with a rotatable locking pin 46 passing through the female part of the link, and having a part cylindrical gap 48. In an alternative arrangement the threaded spigot 19<SP>1</SP>, Fig. 5, is formed separately of the link part 18<SP>1</SP>, and has a head 51 toothed or serrated on its periphery to co-operate with a pin or spring catch 53. In a modified form of toggle shown in Fig. 9, made mainly of sheet metal, the locking lever 21<SP>1</SP> is pivoted to an internal bridge piece 56 on which is rotatably secured a nut 57 mounted on a bolt 58. The hooked ends 27<SP>1</SP> of the locking lever 21<SP>1</SP> co-operate with pins 28<SP>1</SP> secured to the frame 3<SP>1</SP>, and latching of the locking lever is effected by engagement of latch parts 33<SP>1</SP>, 34<SP>1</SP> on the latching lever and locking lever respectively. The throw-out means is incorporated in the latching lever and is constituted by transverse arms or lugs 61 projecting inwardly from extensions 62 of the lever 31<SP>1</SP> which engage lugs 63 on the locking lever.

Title: Fluid flow control system

Filed: 1975-06-11
Abstract: 1513902 Automatic control IVAC CORP 11 June 1975 [28 Feb 1975] 24941/75 Heading G3N  Parenteral administration of liquids is effected by a disposable cartridge syringe 10, having a piston 10c driven by a D.C. stepping motor forming part of a drive subsystem 12. Selective actuation of valves 17, 18, of the tube-pincher or clamp-type, during fill and delivery strokes of the pump is determined by a valve subsystem 19, geared to the drive subsystem. The subsystem 19 provides piston direction signals to a control subsystem 13 which controls subsystem 12 to determine direction and rate of piston drive. The control subsystem 13 provides a fixed motor drive frequency during the fill stroke and compensates, as the desired fluid pumping rate is increased, for the time lost during the fill stroke period, by increasing the drive frequency during the pump stroke. The compensation is spread over the full stroke period by compensating each motor pulse for a uniform position of the time lost during the immediately preceding full stroke. The output of a drop detector and of alarm subsystems (responsive to detection of a bubble, or stalled motor) are fed to the control subsystem 13 and an arrangement is provided to ensure that the piston is positioned at start-up so as to facilitate insertion of a syringe cartridge.

In a system for computing a pulse-rate signal from two input signals A and B, input B, represented by a coded signal, is increased or decreased by a constant amount, the result being multiplied by input A and the result of this being adjusted by a further addition or subtraction. In the particular embodiment, input A, represented by a frequency-significant pulse train, is fed to a binary counter. A " variable " portion of the input B, represented by coded signals on ten lines, gates the outputs of corresponding selected counter stages through a common delay to adder (OR-gate) and subtractor circuits, the other inputs of which receive similar signals gated from the counter under control of a " constant " portion of the input B. The system may be used for weighing material on belts (A being belt speed and B being weight) or measuring liquid mass flow rate (A being volume flow rate and B being density), the outputs going to counters.

Title: Improvements in argon-mercury discharge tubes
IPC: H01J61/72
Filed: 1927-09-23
Abstract: 293,683. Rainbow Light, Inc., (Assignees of Machlett, R. R.). July 9, 1927, [Convention date]. Low-pressure metallic-vapour apparatus.-In tubes of the glow-discharge type containing an atmosphere of rarefied argon and mercury vapour, the vapour is evolved uniformly from the walls of the tube from small mercury mirrors or films distributed along the tube. The light from the tube is blue with clear glass and green with amber glass, the glow in the tube being uniform even at low temperatures. Free alkali metal evolved from the glass and amalgamating with the mercury to produce a striated glow is prevented by using boro-silica glass and by immersing the glass in a weak acid solution such as 2 per cent hydrofluoric acid for several days before forming the tube 2. The tube 2 is then provided with internal electrodes 3 preferably of graphite and is supported by wires 4 in a gasheated or other oven and baked to 450‹ C. whilst being exhausted through a tube 7. Impurities are eliminated from the electrodes by passing a current through the residual air and gases evolved from the electrodes, the current being so large that the electrodes are heated to red-heat or 1000‹ C. After cooling the electrodes and exhausting, argon at 10 mm. is introduced and if a pure argon spectrum is not obtained when current is passed through the tube, re-exhaustion and further argon charges are necessary. Mercury is distilled in small quantities from an external bulb 9 into the bulb 5, the tubes 7, 8 being sealed off at 7<1>, 8<1>. The mercury is passed into the tube 2 by tilting and mechanically distributed over the tube 2, the bulb 5 being sealed off. Small mercury mirrors distributed along the tube are then formed by vaporizing the mercury by passing through the tube a. current slightly greater than the normal current, the tube being locally cooled by spaced copper bars or a copper grid. When the tube cools, further mercury is condensed uniformly in the tube.

A process for the electrolytic treatment of metal members on a fabric tape 1 which incorporates fine wires, e.g. for anodizing aluminium zip-fastener members, comprises passing the tape 1 through an electrolytic bath 3 which is divided by an insulating partition 7 into an anode and a cathode compartment, the top of the partition 7 lying below the normal level 5 of the electrolyte in the bath, and segregating the electrolyte in the two compartments by depressing the level thereof locally on each side of the partition to below the top thereof, the tape 1 rising above the depressed level on passing from one compartment to the next: The level is depressed by air pressure, which may be static or in the form of a blast, introduced through an inverted insulating trough 13. An anode 9 electrifies the tape 1, and a cathode 11 completes the circuit.
