Title: Improvements in or relating to the production of material suitable for flexible films
IPC: C08C19/12
Filed: 1944-06-13
Abstract: A copolymer of butadiene and styrene is added to rubber and the mixture is treated with a halide which without substantially affecting the polymer, converts the rubber into a substance of reduced extensibility suitable for the making of flexible films. Suitable halides are hydrogen chloride, aluminium chloride, stannic chloride and titanium tetrachloride.  According to an example, 10 parts of a copolymer of 75 parts butadiene and 25 parts styrene are milled with 90 parts of rubber; the mixture is dissolved in 1,000 parts of benzene and 50 parts of acetic acid are added to reduce viscosity.  Dry hydrogen chloride is passed into the solution for several hours.  The solvent is distilled with steam and the derivative containing 24.3 per cent. of chlorine is dried at 40 DEG C.  Solutions of derivative yield transparent, slightly elastic films which are tough and flexible. Instead of making a solution of the mixture, sheets may be formed and treated, e.g., with a 10 per cent. solution of stannic chloride in ethylene dichloride.

Title: Improvements in combustion turbines
IPC: F02C3/045
Filed: 1923-04-26
Abstract: 196,931. Dufour, L. April 28, 1922, [Convention date]. Multi-stage centrifugal pumps; section of turbine wheel used as compressor.-A combustion turbine has several pressure stages and wheels which serve as turbine wheels and compressor wheels; these are so arranged that they impart to the gases a portion only of the pressure necessary for the working of the turbine, the remainder being imparted by. an auxiliary centrifugal turbocompressor. The turbine is shown with five wheels b<1> - - b<5> provided with ribs or blades f which project beyond the circumference of the wheels. At the top of the machine the projecting parts of the blades pass into the chambers k<1>- - k<5> through which the gases pass from the combustion chamber n and the tube x, and in these chambers the blades act as turbine blades. The lower part of the machine, comprising more than half its circumference, forms a compressor. The gases from chambers h<1> - - - h<5> pass between fixed guide vanes q and enter the impeller; after leaving the blades f they pass through the diffusers g and chambers l<1> - - l<5> to pipes y<1> - - y<5> leading to sections of the auxiliary compressor. Twelve impeller wheels r<1> - - r<12> are mounted on the auxiliary compressor shaft a<2>, Fig. 3, surrounded by diffusers g<1> - - g<12>. The impellers r<1>. r<2> act in series and discharge through a pipe z' into the atmosphere. The remaining impellers r<3> - - r<12> act in series and the compressor part of the turbine wheel b' is included in the series between the impellers r<9> - r<10>. The compressor part of the turbine wheel b<5> acts in parallel with the impellers r<7>, r<5>, r<3> respectively. The passage of the gases cool the turbine blades. During working, air enters the pipe w', pa,sses through the compressor impellers r<3> - - r<12> and the associated turbine wheels b<4> - - b<1>, passes through the pipe w<2> to the regenerator R<1> where it is heated by the exhaust gases from the turbine, and then passes through the pipe w' to the combustion chamber n to maintain the combustion of the crude petroleum which enters the chamber through the pipe v<3>. The gases of combustion pass through the guide blades m<1> - - m<5> and chambers k<1> - k<5> operating the turbine wheels b<1> - - b<5> as they pass; the last wheel b<5> is operated at a pressure below atmospheric pressure. The hot exhaust gases are conveyed by the pipe z<1> to the regenerator R<1> to heat the incoming gas. thence by the pipe z<2> to the refrigerator R<2> where they are cooled by circulating water, and finally to the discharge pipe z<4> through the impeller r<1> and the compressor part of the turbine wheel b<5> arranged in parallel. Refrigerators may be placed between the stages or groups of stages of the auxiliary compressor and the compressor may be driven by the turbine. The number of turbine wheels placed in series and in parallel with compressor impellers may be varied. Specification 188,322 is referred to. Reference has been directed by the Comptroller to Specification 181,377.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M1/00
Filed: 1929-06-15
Abstract: 332,515. Blackburn Aeroplane & Motor Co., Ltd., and Blackburn, H. June 15, 1929. Divided on 331,366, Spray carburettors.-In a carburettor in which fuel is raised by a rotating wheel C from a constant-level fuel chamber B<4> to a suction nozzle, the chamber B' is of cylindrical form and is pivotally mounted, the movement of the chamber under a varying weight of fuel being utilized to actuate a valve D<1> controlling the flow of fuel through the supply pipe D into the chamber. The chamber B<4> is counterbalanced about its pivot by an adjustable weight B<7>, the position of which may be changed according to the specific gravity of the fuel. As the weight of fuel in the chamber decreases the chamber rises and disengages a pivoted lever D<4> from a stop D<6> attached to the chamber, thus allowing the. valve D<1> to admit more fuel until the level is corrected. The fuel chamber has the end walls relatively close together so that, in conjunction with the cylindrical form of the chamber, the fuel level remains approximately constant for different angular positions of the carburettor. A dash-pot, Fig. 3, may be provided to damp the movements of the fuel chamber, a piston F<3> being fixed to the bottom of the chamber whilst the cylinder F depends from the carburettor casing at the end of an articulated rod F' which projects into the chamber through a segmental opening B<5> that accommodates the fuel nozzle and the fuel supply pipe D. The dash-pot is provided with an air vent F<5>.

Title: Improvements in and relating to sheet feeders
IPC: B65H3/08
Filed: 1943-07-14
Abstract: 564,876. Feeding sheets. HARRIS-SEYBOLD-POTTER CO. July 14, 1943, No. 11471. Convention date, June 10, 1942. [Class 100 (i)] A sheet - feeding device which is especially applicable for feeding small sheets from a pile in overlapped form to a printing or like machine is constructed with a sheet gripper preferably in the form of a suction roller 178 which acts on the rear edge of the pile in conjunction with fixed air-blast devices 116, Fig. 19, and 118, Fig. 2 (not shown), and an oscillating presser - foot 147 which also is fitted with means for forming an air blast. The suction roller 178 is mounted on a pivot 170 carried by an oscillating arm 164, and a gear-wheel 180 on the roller is connected by a gear 181 to a gear sector 184 which is oscillated by a cam on the same shaft 95 which carries the cam for oscillating the arm 164. The roller 170 is constructed as shown in Fig. 10 with two sets of suction apertures 199, 201, and the roller can be secured in either of two positions on its shaft so as to cause either set of apertures to be operative to grip the top sheet of the pile 37 which is controlled by adjustable guides, the pile being kept at a level by hand or automatically controlled means. The roller 178 is provided with two spaced sets of suction apertures, or spaced suction nozzles of different sizes, 208, 260, Fig. 8 (not shown), so as to prevent lateral shifting of the separated sheets. A complete series of separating actions for each sheet is started by fluffing up of the top sheets by the blast devices 116, followed by attraction of the top sheet to the apertures 201 when these are in the position shown in Fig. 17. The roller 178 is then moved upwards and forwards in an epicycloidal path as indicated in Fig. 26 by the line a, b, the sheets being prevented from forward movement by, pivoted front guides 258. The roller 178, after gripping the top sheet, rotates counter-clockwise and the presser-foot 147 moves into the space between the top sheet and the pile, and delivers a blast of air under the top sheet, the blast being cut off from the devices 116, 118. The guides 258 are now moved away from the front edge of the pile and the roller 178 is rotated clockwise to advance the sheet into engagement with sectional feed rollers 56 co-operating with an idle roller 62 mounted in pivoted arms 64. The suction and blast are cut off as the roller 178 and presser-foot 147 return to their starting position, and the blast devices 116, 118 come into action before this return is completed. For overlapping feeds, the separation of the next sheet starts before the prior sheet is withdrawn from the pile. The sheets are finally advanced by tapes 57 to the front stops 33 of a printing or like machine. The machine is adapted for dealing with sheets of different sizes, the pile being controlled by guides adjustable on a cross-bar 240, and the separating devices being adjustable longitudinally of the pile and having splined connection with a drive shaft 85 driven by helical gearing.
