Title: Improvements in and relating to temperature controlling devices
IPC: G05D23/02
Filed: 1930-09-26
Abstract: 364,543. Thermostats. B R I T I S H LAUNDERERS' RESEARCH ASSOCIATION, 17, Lancaster Gate, PARKER, R. G., and HAMPSON, R. E. V., The Laboratory, Hill View Gardens, Hendon, both in London. Sept. 26, 1930, No. 28843. [Class 64 (ii).] The temperature of a heated rotary, oscillating or other moving part of a machine is regulated by utilizing the difference in expansion between the heated part and a rod having a different coefficient of expansion. The relative movement between the two parts may be utilized to control an electric circuit which may operate, with or without a relay, an alarm bell or signal lamp or a valve or switch controlling the supply of heat. The current from the moving part may be conducted through a slip ring or the like. The operating temperature may be determined by altering the position of the contacts or by varying the length of the rod. The relative changes in length of the rod and the machine may be mechanically magnified. In the application to a gas-heated roller 1, a rod 3 of small coefficient of expansion is arranged within the roller, one end being fixed to a bracket 4. The other end carries an arm 5 adjustable by its securing screw 6 and carrying a contact 9 co-operating with a contact 10 on a slip ring 12 carried by the roller. The arm 5 is elastic to avoid damage due to continued heating after contact. The rod 3 may be varied in length by rotating a nut 17 held between the parts 18 of the bracket 4, and the nut may be marked to indicate the corresponding temperature adjustment. The electric circuit may control a gas valve 26. The Provisional Specification refers to the application of the invention to stationary heated members.

Abstract: 221,386. Fauconnier, E., and Simpere, A. Nov. 19, 1923. Carburetting.-A carburettor comprises an outer and an inner casing, the air first entering the outer casing and losing its moisture against the outer walls of the inner casing, and then passing into the inner casing where it is enriched by circulating through slanting channels provided with lengths of corrugated gauze over which the carburetting liquid flows. The outer casing 33 is mounted on two arched tubular members 11 over a water trough 1 closed hermetically by a cover 10 and containing a hollow revolving drum 5, which on rotation draws air through the casing. The casing, Fig. 1, is prismatic in shape, and comprises besides a pair of closed ends an upper flat face 32, two inclined latter faces 33, two lower faces 34 meeting at a re-entrant angle, and two intermediate perforated faces 35. The upper face 32 is apertured to receive the air supply pipe 37 containing the fuel supply pipe 27 connected to a horizontal diaphragm on the inner casing D. The latter comprises a three-branched prism, the side branches being constituted by pairs of sides 41, 42 and the vertical branch by a. pair of perforated vertical sides 43 which support the diaphragm 38 and contain another pair of sides 47 carrying an inverted V-shaped roof 46 and forming a passage F. The carburetting liquid is delivered from holes in the pipe 27 on to the roof 46, and percolates through corrugated gauze sheets 56, Fig. 4, in the branch prisms, the excess fluid passing through the perforated sides 35 on to the gauze covered surface 16 of the members 11, and being collected in troughs 12, The indrawn air, following the path of the arrows. Fig. 1, first passes round the outer sides of the inner casing, the transverse walls of which are shorter than the corresponding walls of the outer casing, and' deposits its moisture thereon and then passes up through the passage F into the branch prisms where it is carburetted. A. valve 40 may be provided in the fuel inlet pipe, and moisture condensed from the air is drained off through a plug 58.

Filed: 1938-10-08
Abstract: 519,253. Colour kinematography. KAMPFER, A. H. Oct. 8, 1938, No. 29209. Convention date, Oct. 8, 1937. [Classes 97 (i) and 98 (ii)] Additive colour films are produced by the simultaneous exposure of four differently coloursensitized narrow gauge films arranged as two bipacks with the emulsions in contact, the films being separately developed and the four simultaneously-recorded images being printed on a film of normal width and in the space occupied by a normal frame. In one method a ray-dividing system is employed, one beam passing through a yellow filter to a green-sensitive emulsion on the front film of one bipack, and then through a red filter to the red-sensitive emulsion of the rear film; the other beam acts on the blue-sensitive emulsion of the front film of the other bipack and on the panchromatic emulsion of the rear film, a black and white image being produced on the latter. A correction filter may be employed in front of the panchromatic film. A space for a sound track may be left at the side or at the centre of the film.

Title: Liquid level control apparatus
IPC: G05D9/04
Filed: 1971-06-23
Abstract: 1359000 Fluid-pressure servomotor systems PHILIPS' GLOEILAMPENFABRIEKEN NV 23 June 1971 [26 June 1970] 29422/71 Heading G3P [Also in Divisions F2 and G1] Apparatus for maintaining the level of a liquefied gas, e.g. nitrogen, in a container 1 between upper and lower limits, the liquefied gas being supplied through siphon 2 from a storage container 3, has two vapour pressure bulbs 6, 7 positioned at the limits, each bulb containing a medium, e.g. nitrogen, under pressure which condenses at the temperature of the liquefied gas, the filling pressure of bulb 7 being for example seven atmospheres and that of bulb 6 four atmospheres, the pressure differential between bulbs 6 and 7 operating a first control valve 8 and, via a duct 19, a second control valve 21 by which the storage container 3 can be communicated either with a pressure vessel 31 or with a vapour outlet 5. If the level falls below bulb 7, excess pressure in duct 17 displaces piston member 9 upwards (as viewed in Fig.1) and, via duct 19, displaces piston member 22 to the left thus placing the vapour space of container 3 in communication with pressure vessel 31 such that liquefied gas is siphoned into container 1. When the level reaches bulb 7, the vapour therein condenses, but compression spring 20 shuts member 9 against seating 18 quickly so that there is enough residual pressure in duct 19 to keep piston member 22 to the left. When the level reaches bulb 6 the vapour therein condenses and spring 20 acts to open valve 8, and the vapour trapped in duct 19 condenses. Spring 33 then moves piston member 22 to the right thereby communicating container 3 with vapour outlet 5 so that no more liquid is siphoned into container 1. Only when the level again falls below bulb 7 will pressure build up in duct 19 to move piston member 22 to the left to recommence the cycle. To provide better sealing and particularly to avoid communication of pressure vessel 31 with outlet 5 during motion of the piston member 22, the members 9, 22 may be provided with O-ring seals as in Figs.2-5 (not shown), and in this case the pressure media may act directly on the faces of the piston members.

Abstract: 1308249 Treating green coffee beans GENERAL FOODS CORP 17 June 1970 [20 June 1969] 29477/70 Heading A2B A method of treating green coffee to remove undesirable flavour and aroma constituents comprises heating green coffee beans for 1-5 mins. in a pressure vessel with water vapour at a pressure of 50-140 p.s.i.g. and a temperature of at least the temperature of saturated steam at the vessel pressure, and relieving the pressure on the beans to less than 8 p.s.i.g. before discharging the beans from the vessel, by venting vapours at a rate to prevent substantial expansion of the beans. The amount of water vapour contacting the beans is sufficient to penetrate the beans but insufficient to raise the moisture content of the treated coffee to above 45% by wt. of the final wet coffee. The process may be carried out in a continuous manner wherein the beans are mixed with water in an inlet pressure lock, fed into an externally heated digester to which steam may be added, and discharged via an outlet pressure lock wherein the vapours are vented. The treated beans may then be roasted and ground.
