Title: An improved density measuring device
Inventor: ROSE DENNIS
IPC: G01N9/34
Filed: 1954-01-28
Abstract: 752,356. Determining specific gravity. ULTRA ELECTRIC. Ltd. Jan. 28, 1955 [Jan. 28, 1954], No. 2632/54. Class 97 (3). A device for the continuous measurement of the density of liquids consists of an axially expansible cylindrical chamber rotatable about its axis and provided with means for the admission and exhaust of the liquid the density of which is to be measured, the axially displaceable part of the chamber serving to operate the device. As shown, a cylinder 1 is closed by a flexible disc 2 clamped against the end of cylinder 1 by a cap 3. Most of the area of the disc 2 is held between discs 4, 5 screwed to the end of a rod 6, movable loosely in cap 3 along the axis of cylinder 1. A compression spring 11 is mounted between disc 4 and the inner surface of cap 3. The liquid the density of which is to be measured is led into and out of cylinder 1 by concentric tubes 8, 10. The device is rotated in bearings (not shown) about the axis of cylinder 1, radial vanes 12 being provided in the cylinder to ensure that the liquid in the cylinder rotates with it. An axial force is produced which moves rod 6 against spring 11, the force being proportional, for a given rotational speed, to the density of the liquid in cylinder 1, and the movement of the rod can be used to operate an indicator. Instead of the diaphragm, rod 6 may be connected to a piston or an extensible bellows.

Abstract: 430,716. Glass manufacture. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Jan. 26, 1935, No. 2635. Convention date, Jan. 27, 1934. [Class 56] A process of sealing a tube into a lamp bulb or similar article comprises heating the open end of the article to fusing temperature while the tube is heated to a temperature below that at which it becomes plastic, and pinching the fused. end of the article about the tube. Apparatus is described of the type in which the articles are mounted on the periphery of an intermittently rotating table which presents them successively to heating stations, an operating station, and annealing stations. Fig. 2 shows this in cross-section through the operating station. The articles 21 are held in clamps 20 supported by brackets 9 mounted on a sleeve 5 which is rotated at all the stations by gearing 7 co-operating with the Geneva gear 3 which rotates the table 1. The brackets also carry a die 11 which at the heating stations surrounds the tube 34 and protects it from the heating jets as shown in Fig. 4. At the operating station the push rods 30, 13 are actuated by the step 31 of the cam 29 so as to raise the tube 34 to the position shown in Fig. 5 while heating jets play upon the article. The pinching jaws 12 which have hitherto remained inactive by reason of the slots 16 in the links 15 are brought into action by the further movement of the push rods effected by the step 32 of the cam, pinching the joint as shown in Fig. 6. The table subsequently carries the article to a series of annealing stations where it is heated to a temperature slightly above the annealing point and then gradually cooled.

A control system for domestic apparatus comprises means whereby the current flowing in the apparatus is maintained at a high value for an initial period and thereafter is controlled at a lower value as required by the apparatus. An electric cooker comprises a heater element 6 supplied from an A.C. source over a rectifying device 7 across one diagonal of which is a silicon controlled rectifier 8, the firing angle of which is controlled by a network including resistors 10, 11 and a capacitor 12. A device 13 sensitive to the cooker temperature is arranged to remove a short circuit across the resistor 11 when the cooker temperature reaches a predetermined value. Thus the rectifier 8 is controlled to fire at the beginning of each half cycle of the A.C. supply when the cooker is initially switched on thereby ensuring rapid attainment of its normal operating temperature after which the device 13 removes the short circuit across resistor 11 whereupon the rectifier 8 is controlled to fire at an intermediate point in each half cycle. The device 13 may be any temperature dependent element such as a thyristor or transistor, a positive temperature coefficient resistor at a temperature operated relay device. The resistor 11 is made variable so that the operating temperature of the cooker can be varied.

Abstract: 552,364. Automatic control system: for steam generators. LOUMIET, J. P., (also known as LOUMIET Y LAVIGNE, J P.). March 7, 1941, No. 3130. Convention date, March 9, 1940. Drawings to Specification. [Class 38 (iv)] Fluid pressure ; fluid level.-The water, fuel and air supplies to a steam generator, in relative proportions approximating to its requirements, under minimum or maximum efficiency conditions, are furnished by a single motor the speed of which is automatically varied to maintain either the steam pressure or the water level constant and the supply of water or fuel and air is additionally regulated in the first case to maintain constant water level and in the second constant steam pressure. The motor may for example be a steam engine, of which an admission valve or Stephenson link mechanism is adjusted by a reversible electric motor, or an electric motor speed controlling resistance of which is similarly adjusted. The supplies of fuel, if liquid, and of water may be regulated by valves adjusted by reversible electric motors. The air supply may be regulated by a mechanical connection to the fuel adjusting valve. Various arrangements using liquid fuel and forced draught are described and the invention is applicable to solid fuel firing. A Bourdon type steam pressure controller may be used but the controllers responsive to steam pressure and to water level which are preferred are each of the gauge glass type described in Specifications 541,840 and 544,130 but are associated with modified electrical relay arrangements which reduce the amplitude of control oscillations by anticipatory control of the cessation of current supply to the servomotor following a change in steam pressure or water level.

Title: Improvements in windscreen cleaners
IPC: B60S1/52
Filed: 1956-02-01
Abstract: 795,483. Windscreen washers. GENERAL MOTORS CORPORATION. Feb. 1, 1956 [Feb. 9, 1955], No. 3176/56. Class 138(1). A windscreen cleaner assembly comprises an oscillatable wiper arm, e.g., 11, Fig. 2, a nozzle 13 carried by the arm and connectable to a liquid supply, a pin 27 carried by the arm towards the free end of the arm and having its axis transversely of the length of the arm and a wiper blade 12 supported by the pin for movement relative to the arm when the blade is oscillated on the windscreen, so that the blade will be behind the discharge of liquid in either direction of movement of the arm. In the embodiment shown in Figs. 2 and 3, a tube 16, to which liquid is supplied under pressure in known manner, is carried within the channelled wiper arm 11 and terminates, beyond the flattened end 22 of the arm in the nozzle 13. The wiper blade 12 having a flexible backing strip 26 is pivotally connected to the arm by the pin 27 on the blade passing through a hole 28 in the arm end 22 and detachably secured by a spring clip 29. The pin is mounted nearer to the inner end than the outer end of the blade and pivotal movement of the latter is limited by ears 23, 24. As the arm oscillates the outer end of the blades causes the blade to pivot as shown in Fig. 3 owing to the greater friction between the outer end and the windscreen. In the embodiment of Fig. 5, the tube 16 is connected to a bore 34<SP>1</SP> in a block 32 on the blade 12, 26. The block 32 is slidable on a pin 35 mounted across an enlarged end of the arm 11. The bore 34 communicates with jets 38, 39 on the opposite walls of the block, the jets being closable by sealing washers 36, 37. As the arm oscillates the block and thus the blade slide relative to the pin 35 so that one set of jets will be directed in advance of the blade whilst the other set on the opposite side of the block will be closed by one of the washers.
