Title: Improvements in the means of charging the explosion cylinders of internal combustion engines with a combustible mixture
IPC: F02B25/00
Filed: 1932-02-23
Abstract: 395,072. Spray carburetters; two- and four-stroke-cycle engines. SLAUGHTER, T., 56, Park Side, Coventry. Feb. 23, 1932, No. 5315. [Classes 7 (ii) and 7 (iii).] In an engine using crank-case compression, and in which the pressure in the crank case is transmitted both to the tops of a float chamber and to a fuel supply tank, the communication between the crank case and the float chamber is opened and closed immediately prior to the opening of the cylinder inlet port, and is temporarily reopened at or about the closing of the inlet port. In the construction shown in Fig. 2, the crank shaft g of a two-stroke cycle engine is formed with an axial passage g<1> provided with ports g<2>, g<3> which register with the transfer passage d and with an orifice h<1> in the housing h, respectively. As the piston b descends air is compressed in the crank case until the port g<2> registers with the passage d and the port g<3> registers with the orifice h<1>. The pressure in the transfer passage is thus communicated to the top of the float chamber e and, if desired, through a pipe i<1> to the upper part of a float chamber j<1> in the petrol tank j. After the fuel injection, the pressure in the float chamber is released through a passage g<4> which registers with the port h<1>. An air pump k may be fitted to the fuel tank to maintain therein a pressure equal to the maximum pressure in the crank case. In a four-stroke cycle engine, the pressure is preferably applied to the fuel only once in two revolutions of the crank shaft by employing ports in the half-speed cam shaft, but the communication between the crank case and the float chamber may be established during each revolution of the crank case.

Title: Improvements in or relating to ascorbic acid derivatives of sulfanilamide derivatives
IPC: C07D277/52
Filed: 1948-02-23
Abstract: Ascorbic acid is reacted with a N1-heterocyclic-substituted sulphanilamide in a solvent to form the corresponding salt. Preferably the reaction is carried out in an anhydrous organic solvent (e.g. methanol, pyridine, propylene glycol) and another miscible organic solvent (e.g. chloroform) is added to precipitate the salt.  The heterocyclic radical may contain nitrogen, or nitrogen and sulphur, the examples showing sulphathiazole, sulphadiazine and sulphamerazine reacted with ascorbic acid.  Preferably the reactants are used in equimolecular proportions.

Title: Improvements in or relating to air-conditioning plants of large, and in particular of industrial premises
IPC: F24F3/044
Filed: 1942-04-27
Abstract: 556,973. Conditioning air. CLIMATOR, Ltd., and BERLOWITZ, M. April 27, 1942, No. 5607. [Class 137] In an air-conditioning system in which means are provided for supplying fresh air and recirculated air, the latter is caused to circulate by one or more subsidiary plants which are independent of the means for providing the conditioned fresh air supply. The fresh air supply is passed through conditioning apparatus which includes a washer, and the recirculated air may be heated or cooled. A distinction is drawn between " return air " which is used air drawn from the enclosure and mixed in the air conditioner with fresh air and " recirculated air " which is not passed through the air conditioner, but which may be heated or cooled independently. In Fig. 1 fresh air supplied at F and return air at R are passed through a conditioning apparatus 1 and supplied through conduits 2, 3 to a theatre 4, return air being carried back by conduits (not shown) to inlet R. The recirculated air is withdrawn by a fan 10 through extraction ducts 12, passed through a heater or cooler 13 and delivered through a duct 11 to the interior. A duct 15 carries surplus air to the outside. In one modification groups of rooms have independent recirculation systems with thermostat or humidistat control to each room and in another modification recirculated air from one room or group of rooms may be returned to another room or group of rooms. Specification 506,441 is referred to.

Abstract: 1,221,414. Disc brakes. NATIONAL RESEARCH DEVELOPMENT CORP. 5 Feb., 1968 [6 Feb., 1967], No. 5633/67. Headings F2E and F2F. A vehicle or shaft-breaking system includes a brake block assembly 21, 22 (Figs. 1, 2) and a flexible walled vessel 24 closed to atmosphere and containing pneumatic or hydraulic fluid. Increase of the fluid content of the vessel causes it to distend and effect movement of the assembly 21, 22, e.g. toward a disc 20 to be braked. Two such vessels are linked by a stirrup pipe (not shown) in the Fig. 1 arrangement. A housing 23 of a vessel has divergent walls whereby a non-linear fluid displacement/ mechanical displacement characteristic is achieved, the mechanical displacement of the block assembly decreasing progressively as the volume of the vessel is increased. Leaf springs 25 return the block assembly after operation or alternatively the natural resilience of the vessel may cause withdrawal. The vessel(s). may be of rubber reinforced with nylon. The system is preferably actuated by means including a master cylinder incorporating a similar vessel.

Sheafing or binding apparatus.- A machine for elevating and sheafing or binding corn and other cut crops comprises two or more parallel revolving picking-up drums 5, 6, Fig. 2, mounted in side members 9 pivoted at 13. The crop picked up by the teeth 7, 8 on the drums is removed from them by a comb 14 bearing on the drum 6, whence it passes to toothed conveyer bands 17 and to the bindertable 23. The side members 9 may be adjusted vertically by a lever 27 and link 26. The moving parts are driven by the wheel axle 4 and endless chains 32, 38, &c. For conducting the corn &c. from the conveyer to the binder a toothed plate 44 is reciprocated by a crank 47. A guide-plate is adjusted by means of a slot and bolt 49. Another device for the same purpose consists of a spindle 54, Fig. 3, carrying two sets of curved teeth 55, the concave sides of which operate on the crop to push it towards the guideplate 48. To conduct the bound sheaves to the side of the machine, a transverse endless-belt conveyer may be used, or may be replaced by a series of curved plates 63, Fig. 2, forming a shoot or guide down which the sheaves pass.
