Title: Improved process for the low temperature distillation of bituminous coal and lignite
IPC: C10B49/00
Filed: 1929-06-17
Abstract: 329,542. Compagnie GÚnÚrale de Distillation et Cokefaction Ó Basse Temperature et MiniÚre (Intertrust) Soc. Anon., (Assignees of International Holding de Distillation et Cokefaction Ó Basse Temperature et Miniere (Holcobami), Soc. Anon.). March 15, 1929, [Convention date]. Coking processes.-In a low temperature carbonization process bituminous coal or lignite is heated slowly in a thin layer (8 to 10 cms.) until the external temperature reaches 450' C., this being maintained until certain volatiles are distilled off, and until the least hot portions of the mass is at 350‹ C. In this stage the temperature is raised by 25' every 15 minutes. The temperature is then rapidly increased to 500 to 550‹ C. Semi-coke containing 8 to 12 per cent of volatiles, and uncracked low temperature tar are obtained. Suitable retorts for the process are described in Specification 229,880 and 308,760..

Title: Improvements in pneumatic brakes for vehicles
IPC: B60T13/36
Filed: 1926-07-27
Abstract: 277,780. Maley, A. W., and Taunton, E. M. July 27, 1926. Fluid-pressure.-In brake systems for tramcars and like vehicles, of the kind in which application is effected either by the admission of compressed air to the brake cylinders from a reservoir through the motorman's valve to a train-pipe or by the operation of an emergency valve due to the failure of the pressure in a pressure pipe, the piston of the emergency valve actuates the valves proper through non - reversing mechanism so that the seating springs of the valves do not to an appreciable extend tend to move the piston. One face of 'the valve piston is connected to the reservoir through ports which are sealed by the piston in its operative position, a leak being provided however whereby the piston is returned. As shown the system comprises a main reservoir 20 connected through the piston chamber 4 of an emergency valve and ports 23, 24 to a pressure pipe 27 and to an auxiliary reservoir 21 by port 28. The rod of the valve piston 13 is provided with cam surfaces 16, 17 adapted to engage bell-crank levers 18, 19 which operate valves 5, 6 seated by springs 7, 8. Normally, by reason of the difference in area of the two faces of the piston 13 subject to the pressure in the reservoirs 20, 21, this piston is raised so that the valve 5, 6 are respecticely held in the closed and open positions. The motorman, by opening a valve 29, permits air to flow from the reservoir 20 through the pipe 27, pipe 26 and valve 6 to the brake cylinders 25 to apply the brakes. Release is effected by opening the valve 30 to connect the pipe 26 to atmosphere. If the pressure fails in the pipe 27, as by the opening of the valve 31 by the motorman, the piston 13 is moved downwardly permitting the valve 6 to close and opening the valve 5. Air from the auxiliary reservoir 21 then flows to the brake cylinders 25 through the valve 5. The valve piston 13 in its lower position seals the ports 23, 28 and the valve spring 7 has no tendency to lift the piston from its seating. The pressure on the two faces of the piston slowly equalizes however through the port 24 and returns the piston and the valves to the position shown. A main reservoir only may be employed in which case it would take the place of the reservoir 21, the port 23 being sealed and the port 24 being disposed adjacent the port 28.

Abstract: 456,918. Moulding synthetic resin for use on rejecting surfaces. KAMPFER, A., 16, Herbartstrasse, Charlottenburg, Berlin. July 1, 1935, No. 18759. Convention date, June 30, 1934. [Class 87 (ii)] Faceted recesses in reflecting surfaces of sheet metal 3, particularly for making signs, are filled with synthetic resin to form a flat surface by laying the resin in the recesses in the form of threads such that on spreading laterally they completely fill and cover the recesses to form a flat surface. A front or cover sheet can then be applied to the flat surface in order to make a reflecting sign. The sheet 3 is conveyed along a table by rollers 5<a> with surfaces shaped to correspond with and engage the facets. The resin-applying device 4 comprises two concentric cylinders 4<a>, 4<b> with nozzle apertures 4<c> corresponding to each of the recesses transversely of the sheet. The size of the apertures may be varied by relative rotation of the cylinders. Heating chambers 6, 7 are provided for the cylinders and thermoplastic synthetic resin is introduced under pressure through a heated pipe. A heatradiating plate, heated electrically or otherwise may be attached to the device 4 and so warm the material subsequently to laying it on the plate and the bottom may also be heated by pipes under the conveying table. Two pairs of rollers 5a may be provided to assist in maintaining the recesses in the sheet 3 in register with the nozzles 4<c>. The synthetic resin may be a viscous polymerization product used at 80 to 150 degrees C. and it may include softening agents, the polymerization being conducted to a degree from 275 to 330 and preferably 300. Polyvinyl or polyacrylic compounds or polystyrol may thus be used.

Title: Improvements in and relating to photographic framing masks
IPC: G03B21/64
Filed: 1952-07-25
Abstract: 722,295. Photographic framing masks. NARBETH, H. July 25, 1952, No. 18880/52. Class 98 (2). A framing mask comprises two superposed flat elements each having a cut-out portion defined by two rectilinear edges meeting at right-angles, the elements being so juxtaposed that the edges of the cut-out portion of one element intersect the edges of the cut-out portion of the other element at right-angles to define together a rectangular framing aperture, the dimensions of which are infinitely and proportionately variable within limits on relative movement between the elements in the direction of the diagonal of the framing aperture which intersects the meeting-points of the two cut-out defining edges of each element, interengaging means being provided between the two elements to guide them during relative movement in the direction of the diagonal, the guiding means being located outside the largest aperture to which the mask can be adjusted. As shown, the mask is made of opaque plastic, and consists of a sheet 34 slidable in a pocket-like part 32. The walls of part 32 have registering apertures with sides 44, 46 meeting at a right-angle, and sheet 34 has a notch with sides 48, 50 meeting at a right-angle, the sides 44, 46, 48, 50 forming a rectangular aperture, the diagonal d of which lies in the direction of movement of sheet 34. The size of the aperture can thus be varied, but the ratio of its dimensions is constant. When the mask is laid over a print from a negative to be enlarged, the effect of enlarging the negative to a size having dimensions in the same ratio as those of the aperture can be judged. Several masks with dimensions of different ratios may be used to choose the best shape of enlargement. Several modifications are described. The part 32 may be open at both ends, and two additional sheets may slide within it to define an aperture with dimensions in a different ratio. The part 32 may have rectangular apertures within which two slidable sheets define a variable aperture. Two slidable sheets may engage each other by dove-tail grooves and guides, dispensing with part 32. Two sheets sliding in part 32 may each have a sheet pivoted thereto, the sheets having rectangular notches defining an aperture the ratio of the dimensions of which may be varied by turning the notched sheets about their pivots.

Patent GB-263507-A (GB)
Title: Means for manufacturing metallic bellows
IPC: B21D15/06
Filed: 1925-07-25
Abstract: 263,507. Moore, H. R. G., and Rigby, T. P. July 25, 1925. Bellows. - In making cylindrical metallic bellows, particularly for measuring fluid pressures or for operating mechanism through the agency of fluid pressure, after forming and preliminarily corrugating the shell, the corrugations are deepened to final form by spinning in an apparatus having two eccentrically mounted and rela.- tively adjustable narrow internal rolls. The shell may be formed by cupping a blank and then drawing through a series of dies of diminishing bore or may be formed by spinning in a series of operations, annealing being effected after each operation. A disc of phosphor bronze &c. may be first spun into the form shown in Fig. 2 on a steel mandrel, being deepened in the next operation and then spun into cylindrical form. In the next operation, Fig. 5, a conical end is spun on a brass cone fitted into the mandrel and a hole then cut in the end to facilitate gripping during annealing operations and subsequent operation in the lathe. The shell is then completed to the desired length in three operations by an inclined roller 1, Fig. 9, having its corners ground in the form of a quarter ellipse so that the work hugs the mandrel closely. The mouth of the shell is trimmed off square and formed with a shallow stiffening flange. The shell is then corrugated in four operations. In the first operations corrugations of the form shown in Fig. 15 are spun in the shell which is placed on a collapsable mandrel consisting of box wood sections 2, Fig. 14, with equi-distant collars, mounted on a core, preferably tapered. Annealing is then again effected. For the subsequent operations which deepen the corrugations and contract the shell axiallv the shell is secured to a chuck 14, Fig. 15, on a lathe nose adapter 13 and is corrugated by a spinning roller engaged between internal rollers 3, 4 loosely mounted on a shaft 5 which is eccentrically mounted in a tube 6 secured to a tool post 12 having a hand rest 9. A pointer 10 on the tool post indicates the position of the roller 3. The shaft 8 is adjusted in the tube by a handle 7 so as to set the rollers to the required depth and to withdraw them for removal purposes and for moving them from one corrugation to the next. The roller 3 has a long boss on which the roller 4 is slid during operation by a non-rotatable barrel 8 of similar eccentricity to the shaft 5. The barrel is grooved to engage a collar on the roller 4 and slidably supports a hard wood ring 15 for supporting the open end of a long shell. Spinning tools and rollers of successively reduced thickness are used in the three final operations so that the rollers may be wide enough in the earlier operations to support the shell against the pressure of the tool and in the last operation narrow enough to strain harder the outer curves of the corrugations. The flanged end of the shell is spun over in the second operation to form a head and the final annealing effected after the first of these three operations.
