Title: Improvements in absorption refrigerating apparatus for vehicles
IPC: F25B49/04
Filed: 1927-05-21
Abstract: 271,512. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System Aktiebolag). May 22, 1926, [Convention date]. Refrigerating, absorption machines for; refrigerating-chambers.- An absorption machine fitted to a railway car has its surfaces to be cooled arranged on the outside of the roof, floor or walls so as to be exposed to the air currents, and means are provided for reducing the supply of heat to the generator in accordance with reduced speed of the vehicle or of the air current due to the motion or to the wind. The machine shown operates on a continuous cycle and comprises a generator K, absorber A and evaporator G inside the vehicle and a condenser C on the roof. The absorber A and evaporator G contain a pressure-equalizing inert gas and the liquir circulation is effected by a heated riser coil. The evaporator has gills or vanes 14, and the absorber has a cooling-water jacket, the water being circulated through pipes 18, 19 and through an aircooled coil D arranged alongside the condenser. The generator is located in a flue 32 so as to prevent the combustion products from entering the vehicle, and the rectifier V is arranged in a ventilating shaft 33 so as to be air cooled. The heating means may consist of a gas burner B, an oil-gas burner, or an electric heater, and the regulation may be effected by a centrifugal device R, driven by bevel gear 21 from the axle and controlling a gas cock 28. An alternative regulating means comprises a flap 40, Fig. 3 extending from the side of the vehicle in the air stream and urged by a spring 41 in a direction to close the gas cock 49, but moved to open the cock when the vehicle is travelling or the wind is sufficient to produce satisfactory cooling of the condenser and water cooler. The condenser and water cooler may be protected from the rays of the sun by coverings 30, 31, Fig. 1.

Title: An improved means for controlling the operation of automatic weighing machines
IPC: G01G23/00
Filed: 1935-05-10
Abstract: 455,145. Electric remote control systems. AVERY, Ltd., W. & T., and HILL, T. B., Soho Foundry, Birmingham. May 10, 1935, No. 13747. [Class 40 (i)] [See also Group XXXIX] An automatic weighing-machine is controlled from a remote point to make a predetermined number of operations. At the control point the shaft 18 is turned to lift roller 16 out of notch 15a in cam 15 and shaft 11 is manually rotated until the number plate 14 indicates the required number of weighings. Roller 16 is then riding on the edge of cam 15 and mercury switch 19 is closed. Press-button 26 is then operated to tilt mercury switch 23 so that magnets 20 and 24 are energized, magnet 20 holding the press-button 26 operated and magnet 24 releasing the automatic weighing apparatus. As each weighing operation is completed, mercury switch 6 closes to energize magnet 8 and pawl 9 is operated to step ratchet wheel 10 and shaft 11 in a clockwise direction. When the shaft 11 has been thus reset roller 16 drops into the notch 15a and the mercury switch 19 opens the control circuit. Magnet 24 releases the lock on the machine and magnet 20 allows press-button 26 to restore. Lamp 25 indicates when a machine is working. A number of machines can be controlled by the same setting mechanism if required. Specifications 29390/97, 9923/07, [both in Class 40], 10539/12, 18122/13, 141,711, [all in Class 40 (iv)], and 348,154 are referred to.

IPC: C07D307/50
Filed: 1917-09-26
Abstract: 129,025. Ricard, E. June 26, 1917, [Convention date]. Furfural.-In making furfural by the action of acids such as hydrochloric, sulphuric, or formic acid, or chlorides such as calcium or zinc chloride, upon cellulosic or carbohydrate material, the reaction is carried out so that the furfural is distilled off as rapidly as it is formed, the vapours are washed to remove acid vapours, &c., and the furfural, after condensation, is distilled in vacuo. The boilers A, A<1>, used alternately, are charged with a cellulosic material, such as kapok, he!d between perforated plates b, and hydrochloric acid of 13-14 per cent strength is supplied from a tank R. The boilers are heated by coils, double bottoms, or heating-jackets to produce rapid distillation. The vapours pass through a rectifying- column B to a condenser C. The condensate separates into two layers in a receiver D, the lower layer of furfural flowing into a tank E, and the aqueous layer being passed down the column B to remove acid &c. from the vapours rising through the column. The reagent is drawn from the boilers through a filter G to the receiver R for use again. The spent kapok is washed with water from perforated pipes c, and removed through man-holes d. Water may be removed from the furfural in the tank E by cooling, and the furfural then distilled in vacuo from the still. F.

[Class 40 (iii)] A device for indicating or controlling the liquid level in a steam generator or other vessel comprises a tube with upper and lower connections to the generator respectively above and below the normal liquid level, oppositely disposed windows in the tube at a suitable level, an opaque float within the tube, a source of light directed into one window and a photo-electric cell opposite the other window so that the movement of the float consequent upon the variation of the liquid level from a predetermined value effects operation of the cell to actuate a control or alarm device. As shown in Fig. 1, the main liquid container 11 is connected by upper and lower pipes 12, 13 to the tube 10 provided with oppositely disposed windows 18 retained in position by shouldered rings 20, washers 19 and inner rings 24. Anopaque float 26 supported by the liquid column is held by a cross-bar 25 at a predetermined level in a position in which it prevents light passing from a source 30 through the windows 18 to a photo-electric cell 34 disposed behind a window 36 in a casing 33. In an alternative arrangement, the light beam is normally cut off from the photoelectric cell by an elongated float which on falling below a predetermined level allows the light beam to impinge on the photo-electric cell arranged to operate a control or an alarm. Circuit arrangements suitable for the operation of the alternative arrangements are described in Specification 597,639.
