Title: Device for controlling the flow of liquid refrigerant to the compressor of a refrigerating plant
Inventor: BRANDIN JOHAN AXEL IVAR
IPC: G05D16/12
Filed: 1953-11-02
Abstract: 725,925. Refrigerating. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. Nov. 2, 1953, No. 30229/53. Class 29. [Also in Group XXIX] In a compression refrigerating system having a liquid trap 1 in the suction line wherein refrigerant enters through a pipe 2, the gaseous part passing to the suction pipe 3 and the liquid meeting a baffle 5 and passing through a filter 4, the liquid drains through an annular aperture 6 to a float chamber 7 and, on accumulation of liquid, the float 9 rises to cause a sleeve valve 10 to close the entry ports 12 of the suction pipe 3. This creates a pressure difference between the chamber 7 and the suction pipe and the liquid in chamber 7 is then drawn slowly through an inverted U- shaped narrow pipe 13 into the suction pipe. Oil is also returned by this path. The highest part of pipe 13 is at such a height that liquid flows through it only when the compressor is operating. The float is filled with compressed air and has a greater weight than that of the displaced liquid, the difference being taken up by a spring suspension 14. In a modification, Fig. 2 (not shown) the liquid refrigerant passes into a spring-supported open-topped receptacle which moves down to close the entry ports of the suction pipe and a narrow pipe similar to pipe 13 dips into the receptacle to convey liquid to the suction pipe. The pipe 13 may be replaced by a narrow pipe leading direct from chamber 7 to the suction pipe and having a valve automatically closed when the compressor stops.

Title: Improvements in speed gear boxes for rear axle
IPC: F16H3/06

Abstract: 370,876. Change-speed worm gearing. DURAND, P., 31, Rue BorghÞse, Neuilly-sur-Seine, France. Oct. 9, 1930, No. 30249. Convention date, Nov. 19, 1929. Void [Published under Sect. 91 of the Acts]. [Class 80 (ii).] The Specification as open to inspection under Sect. 91 (3) (a) describes a change-speed gear comprising worm-and-wheel pairs alternatively and separately active. Worm-wheels 1 .. 4, Fig. 2, supported so as to turn loosely are constantly meshed by worms such as 12, Fig. 1, each worm turning with one of four hollow clutch heads 11a .. 14a fixed in position. The driving-shaft 22 is connected by a universal joint 21 to a stub-shaft 20 supported in a bearing block 23 so as to move parallel to itself. Shaft 26 carries a clutch head 19. Block 23 is connected by a rod 56 and arm 55 to a sleeve 39 splined on driven shaft 42 and carrying a clutch head 38. Thus clutch heads 19, 38 are connected so as to engage respectively the worm and the worm wheel of the same pair. To change speed, a control lever 31 is moved out of a look notch 36 whereupon its heel 33 moves shaft 20 withdrawing clutch head 19 from engagement. Lever 31 is then slid in transverse notch 3, 2, 1, R to a new gear position, carrying shafts 20, 39 and clutch heads 19, 38 laterally with it. On release of lever 31, a spring 28 thrusts head 19 into engagement with one of the hollow heads 11a .. 14a, establishing the drive. One of the worm pairs may drive reversely. In Fig. 2 is shown the adaptation to a vehicle in which the driven shaft 42 is connected to the differential casing 49 by a friction clutch 48 which is connected so as to be operable from the main clutch pedal. This subject-matter does not appear in the Specification as accepted.

Abstract: <PICT:0688788/III/1> <PICT:0688788/III/2> A device for depositing electrostatically liquids such as paint or varnish on to conducting surfaces consists of a tubular fitting or noozle of insulating material, e.g. quartz, silica, glass, or transparent artificial resin, containing the material to be deposited, in the avis of which is disposed an electrode at a potential difference of the order of 10,000 to 15,000 volts with respect to the object being coated, the electrode having its extremity located at a predetermined distance from the mouth of the fitting, ensuring the necessary resistance to prevent disruptive discharge from the electrode to the surface being coated.  Preferably an earth lead is connected to a point in the substance to be deposited at a suitable distance from the entry point of the high tension electrode to protect users against the danger of electrocution.  The surface which is to receive the coating may be stationary while the nozzle is movable, or the object may be movable, the nozzle may also receive an axial motion perpendicular to the surface being coated.  In Fig. 3, the liquid from reservoir 2 passes into the nozzle 1 in which are disposed the high tension electrode 4 and the earth lead 5, the liquid being projected from the nozzle on to the object to be coated.  In Fig. 5, which illustrates a machine in which tubes may be varnished, a framework 17 supports a revolving barrel 8 carrying a number of chucks 9 holding the tubes 11.  The chuck that comes into alignment with the nozzle 1 is rotated while the nozzle advances within the tube under the action of the cam 12 pushing the supporting carriage 13.

The mixing chamber has inlet control valves 9, 10, 11 for fuel, e.g. acetylene, an oxidant, e.g. oxygen, and an inactive gas, e.g. nitrogen, which mix and then pass through a three-way connector 22. Two other inlets 26, 27 to the connector 22 communicate with a source of inactive gas, one via a gas-pressure reducer. The two inlets are used respectively (a) to scavange the safety coil upon feeding the explosive mix to the combustion chamber, and (b) to scavenge the coil and combustion chamber 1 after ejection of the coating material. The proportioner includes a spool 31 axially slidable to move a cross-bore therein from communication with a hopper 33 to communication with the combustion chamber 1 via line 34.

Abstract: 955,094. Timed control of electric circuits. C. T. HEINLEIN. Sept. 5, 1960 [Sept. 8, 1959], No. 30606/59. Heading G3T. In an apparatus for controlling the operation of a sound device, first and second cyclically moving members, driven by a common driving means have respectively shorter and longer periods of rotation, the first member being effective to control the period of operation of the device and the second allowing the first member to operate only once in the longer cycle. In operation a manually operated push button 14 (Fig. 2) is pressed in order to start a motor 1 and consequently to drive a gear 23 on shaft 3. Initially a projection 47 on gear 24 is in engagement with an end 46 of spring biased lever 40, switches 13 and 11 at this time being in the position shown in Fig. 2 so that amplifier 7 is operated. Arm 35 which is attached to shaft 3, drives a plate 31 and hence a shaft 5, by engaging a projection 32 on the plate 31. A tone generator 6, consisting of a drum 26 having raised pins which strike comb 28 upon rotation of the drum to produce a signal which is fed via a pickup device 27 to the amplifier, is driven by shaft 5. After a short period, projection 47 releases the lever 40 which thereupon is urged against an operating button of the switch 13 and at the same time an abutment (not shown) on shaft 5 strikes the operating arm 52 of the switch 11. The amplifier is thus maintained energized until the abutment moves away from the arm 52 after about a quarter of a revolution of the shaft 5. After one revolution of shaft 3, a further projection 33 on plate 31 drops into a hole 34 in mounting plate 25 thus preventing further rotation of shaft 5. When projection 47 next strikes the end 46 of the lever 40, the switch 13 is released so as to cut-off the motor and projection 33 is forced out of the hole 34 by a projection 44 on the lever 40 so as to ready the apparatus for the next operation.
