Title: Improvements in or relating to absorption refrigerating apparatus of the inert gas type
IPC: F25B15/10
Filed: 1932-01-20
Abstract: 383,798. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Platen-Munters Refrigerating System Aktiebolag; 2, Norrmalmstorg, Stockholm. ) Jan. 20, 1932, No. 1763. Convention date, Jan. 20, 1931. [Class 29.] Absorption systems.-In a continuous-cycle inert gas system the flow resistance in the gas conduit between the evaporator and absorber is automatically varied in correspondence with the liquid level in the absorber dependent on the refrigerating output, in order to avoid loss of efficiency. In the apparatus shown in Fig. 1 and comprising the usual generator 10, condenser 12, evaporator 13, gas heat exchanger 15 and absorber 17, the cross-sectional area of the conduit 16 through which the gas mixture flows from the evaporator to the absorber is restricted by a rise of liquid level in the absorber consequent upon a reduction of the heat supply to the generator to suit a restricted output of the evaporator. As shown in Fig. 2, the conduit 16 may be provided with a sump-like extension 27 in which unevaporated refrigerant from the evaporator may collect, and with a baffle 29 depending towards the liquid sump. The unevaporated refrigerant displaces solution into the absorber and reduces the concentration of the solution in circulation. At the same time the gas flow is restricted. The sump 27 may be replaced by a tubular bend.

Title: Improvements in rotors for rotary wing aircraft
Inventor: WATSON KENNETH

Filed: 1954-01-21
Abstract: 751,109. Rotary wing aircraft. SAUNDERS-ROE, Ltd. Dec. 14, 1954 [Jan. 21, 1954], No. 1840/54. Class 4. A rotary wing aircraft rotor hub comprises a hollow beam 10 centrally supported by a see-saw mounting 11 on the rotor shaft 14, blade attachment members 18 at the ends of the beam which are rotatable for pitch charges, and a pre-tensioned torsion bar 30 within the beam and attached at its opposite ends to the members 18. The shaft 14 includes passages 15, 16 for fuel, and 17 for starting air for blade tip pulse jet engines, and has a rubber buffer 38 to limit the rocking of the beam. Each blade attachment member comprises a sleeve mounted on the beam by thrust bearings 19, 20, and alignment bearings 21 and terminating in forks 28 formed with sockets 29 for attachment of the blades. The axes X-X of each pair of sockets 29 are inclined so that when stationary the blades are coned upwards. The torsion-bar 30, which may consist of a plurality of sectorshaped members 31, or a plurality of spring plates, or a hollow slotted cylinder, is threaded at each end 32 to receive a nut 33 abutting the end of each sleeve 18, so that the nuts 33 can put the bar 30 in tension, preferably so that at normal rotative speed, the centrifugal load is taken entirely by the bar 30. Horns 34 secured by straps 36 and removable shear pins 35 extend from each sleeve for attachment to pitch change mechanism, cyclic pitch changes rotating bar 30, and collective pitch changes applying torque. In a modification, the axes X-X of sockets 29 are made at right-angles to the sleeve 18, but the beam 10 is kinked so as to incline upwardly at each side. Bar 30 may then be similarly kinked.

Abstract: 690,586. Broaching. THOMPSON BEACON WINDOWS, Ltd., J., and RATCLIFFE, J. Jan. 24, 1952 [Jan. 29, 1951], No. 2153/51. Classes 83 (iii) and 83 (iv). Welded joints.-A machine for dressing the welded corners 26 of metal window frames and the like comprises a power-driven rotary head 10. having a cutter or cutters 56-58 which, during a single revolution of the head, operate upon the external side faces and the apex of the frame corner to remove welding sprue thereon. The main shaft 12 of the machine is rotated by an electric motor driving through a fluidpressure operated clutch 21 and bevel-gearing 18, 17. The frame 26 is clamped between fixed jaws and a jaw 29 movable through a yoke 32 by a fluid-pressure piston 35X. When the piston is advanced by operation of a pedal 41, a port 43 is brought into register with a passage 46 which communicates with the means for engaging the clutch 21. The shaft 12 is then rotated and the three sets of cutters 56 ... 58 trim the top and bottom surfaces and the corner of the frame. Springs 60 permit the upper cutter 58 to accommodate frames varying slightly in thickness. When a cam 54 on the shaft 12 actuates an exhaust valve 52, the clutch 21 is disengaged and, shortly afterwards, a cam 66 on the bevel-wheel 17 actuates means 39 to return the piston 35X and the pedal 41 to their initial positions. The shaft 12 is brought to rest by an adjustable wooden brake 74 engaging a high spot on the shaft. The clutch may, alternatively, be leveroperated and the pedal be replaced by a manual control.

Title: Improvements in and relating to quartz working
IPC: C03B27/06
Filed: 1925-01-24
Abstract: 228,191. British Thomson-Houston Co., Ltd., (Assignees of Miller, L. B.). Jan. 25, 1924, [Convention date]. Fused silica.-A method of preparing fused or vitreous silica consists in heating crystalline quartz until it becomes plastic, passing the plastic mass through a passage of gradually decreasing diameter in order to squeeze out the bubbles and cavities, and then allowing it to congeal. The quartz is fused in an electric vacuum furnace, of the type described in Specification 20809/04, comprising a helical resistor 5 surrounded by a refractory screen 12 and enclosed in a tank 1 from which the air can be exhausted. The material is packed into a receptacle 15 which is attached to the top of a cylindrical crucible 14 provided with holes 18 to permit the escape of gases, the throat 16 between the receptacle and the crucible being tapered as shown. The crucible is placed in the resistor, the tank is evacuated; and the temperature is raised steadily until the quartz softens and slides into the crucible 14. As the plastic mass slides through the throat 16, it is constricted and any cavities, together with the low pressure gases they contain, are squeezed to the top of the mass. The mass is then allowed to congeal and forms a slug or ingot of substantially the same cross section as the lower part of the throat 16. Specification 189,926 also is referred to.

Title: A torsion balance
IPC: G01G3/10
Filed: 1960-01-21
Abstract: 936,034. Torsion balances. AGFA A.G. Jan. 21, 1960 [Jan. 22, 1959], No. 2306/60. Class 143. A torsion balance is provided with a reversible electric motor and associated means for detecting unbalance of the beam whereby the motor is controlled to adjust the torsion spring to counterbalance the load. The adjustment takes place in two stages, viz.: an initial rapid movement which overbalances the load followed by a slow return to balance. The beam 16 is supported by crossed blade springs 17, 18 defining a pivot axis 23 which coincides with the axis of a coil spring 24 which constitutes the torsion element. The motor (not shown) tensions this spring in response to the obscuring of a photo-cell 6 whenever the beam tilts in response to loading at 31. As the balance position is passed through, the control circuit, Fig. 6 (not shown), causes an eddy current brake to be applied to the motor, so that the return movement of the beam, controlled by a second photo-cell 8, takes place at low speed and ceases with the beam in balance when both cells are unobscured. The total net movement of the motor shaft is used as a measure of the weight of the load, and this may be indicated by a counter associated with the motor. The reading of the counter may be transmitted to another motor which drives recording mechanism to provide a printed or punched card record of the weight. Alternatively, a graduated scale 9, Fig. 1 (not shown), may be mounted on the motor shaft and read in relation to a fixed pointer.

The surface 11 may be part of a slide element which directs the body into a branch of the distributing system. By measuring the time between the signals obtained from two impact surfaces, the speed of travel of the bodies may be determined.

The blade C is formed with a piece T having two flat surfaces on which bears a spring D in the head so as to hold the blade in either the open or the closed position. The blade C is formed with recesses H to prevent the hair moving along the roller. The use of this form and a form with a smaller recess for a thin tress are described in detail. In a modification, the roller A is threaded internally and runs on a screwed rod secured to the head V so that the hair is wound helically. A small brush may be pivoted to the blade C to brush the hair as it is wound.
