Inventor: KILBURN BERTRAM EDWARD DUNBAR
IPC: C10B39/02
Filed: 1918-03-07
Abstract: 120,329. Kilburn, B. E. D., (Sulzer frÞres, Soc. Anon). March 7, 1918. Cooling discharged materials.-Hot residues from distillation processes, such as coke, are cooled by the repeated circulation through them of a body of air, the oxygen of which is taken up in the early stages of the process. The apparatus shown comprises a number of water-jacketed receivers B mounted in a setting M, and having around them baffled flues Z. The air is circulated by a fan G, and passes by the pipe L<1> through the material, then around the receivers through the flues Z, and finally back to the fan by way of the pipe L. The jackets of the receivers are connected by flow and return pipes to a boiler A. The direction of circulation of the air may be reversed at intervals, and the speed of the fan may be controlled in such a manner that the rate of transfer of heat to the water is equalized.

Title: Improvements in and connected with the actions of organs and like musical instruments
IPC: G10B3/06
Filed: 1922-02-10
Abstract: 197,403. Walker, F. P., and Walker &. Sons, Ltd., J. W. Feb. 10, 1922. Organ actions; soundboards.-A unit action to be inserted in a wall of a wind chest or duct other than the wall into which the pipes or reeds are inserted, comprises an electropneumatic motor connected to the pallet, the motor controlling valve being preferably formed as an armature-plate rocking on a fulcrum between two inclined ports. The pallet and its seating may be of stream-line formation. In the Figure, the unit action is carried on a base plug f of ebonite, metal &c., which on being given a slight turn when inserted in the wind-chest c makes the circuit connections of the electromagnet v. The pallet e guided by wires 7 is mounted with screw adjustment on the rod 2 which in turn is mounted with screw adjustment on the top board r of the cylindrical bellows-motor s, the lower end of the rod 2 cushioning in its lower position on a piece of resilient material 6 carried by a perforated disc o. Wind-pressure on the motors is normally equalised, reaching the interior by a groove l, passage k and port h, allowing a spring q to distend the motor and close, the pallet e. The wind-pressure normally tilts the valve-plate m of circular or other shape, to close the atmosphere port j. Energization of the electromagnet from a kev closes the wind-port h and opens the atmosphere port j, the air exhausting from the motor tending to hold the valve-plate m seated on the port h owing to the apertures in the disc o being arranged over that port. A second groove. l<1> may be provided to enable the unit to be inserted with the port k either to the right or to the left. In a modification the pallet e is mounted directly on the top board r of the motor, the pallet seating being carried at the lower end of a depending throat-tube. In another modification, the motor s constitutes a primary motor actuating, instead of the pallet, a rock-valve with inclined faces controlling a secondary motor on' which the pallet is mounted. The pallet may have a central cone 29 with concaved surface to seat on a wooden or metal annulus 28a of corresponding stream-line formation, and according to one of the Provisional Specifications the cross-sections may be other than circular. When the unit action is inserted in a side wall of the chest, the pipes may stand over ducts formed in a lateral extension of the lower part of the chest, a throatchamber extending across the chest. Accommodation for tall pipes is thus obtained and a second chest may be arranged over the first.

Title: Improved process and apparatus for edging sheets of cardboard, plates of glass and similar objects
IPC: B31F5/08
Filed: 1931-02-09
Abstract: 371,079. Binding edges of sheet material. CASSEGRAIN, P. A. G., 67, Boulevard de Metz, Rennes, Ille-et-Vilaine, France. Feb. 9, 1931, No. 4059. Convention date, Feb. 12, 1930. [Class 16.] In apparatus for edging with a strip of paper, fabric, &c., sheets of cardboard, plates of glass, &c., the cardboard sheet or other article is advanced edgewise at right-angles to the paper strip, which it meets in the centre of its width and carries between fixed members, wherebv the strip is turned over on both sides of the leading edge of the sheet, to which it is secured by adhesive, the free ends of the strip being similarly applied to the side edges of the sheet. The edging of the sheet is completed by passing it again through the apparatus with the opposite edge leading. The sheets are contained in a magazine A, Fig. 1, from which the lowest sheet is withdrawn by tappets 10 on an endless chain 7. The edging-device comprises two sets of blocks 11, Fig. 5, mounted on bars 12 and separated by a passage through which the sheet B passes. The distance apart of the two sets of blocks, and of the individual blocks of each set, can be varied to accommodate sheets of different thicknesses and of different widths. At each side of the series of blocks is a device in the form of a half-funnel, narrowing to a horizontal gutter, which is adapted to bend the edging-strip around the corners of the sheet. The paper edging-strip 18 is drawn from a bobbin 19, and passes through a gumming or pasting device 21, and over a block 23, Fig. 9, having an inclined edge, by which the strip is turned, so as to travel horizontally across the path of the sheet. The end of the strip is seized and drawn along by pincers 26 on a carriage 28 sliding on a bar 29. When the strip is released by the pincers, it is held against the face of the blocks 11 by suction-ports 37, Fig. 5, and is then severed by shears 41, 42, Fig. 9. After passing between the blocks 11, which apply the strip, the sheet passes between pressure-rollers C, D, Fig. 1, and is then removed by endless bands 69. The sheet is thus edged on three sides, as shown in Fig. 12.

Patent GB-676715-A (GB)
Title: Improvements in or relating to guanidine thiocyanate
Filed: 1950-02-17
Abstract: Guanidine thiocyanate is prepared by heating urea and carbon disulphide in a closed reaction zone at a temperature of 190 DEG  to 450 DEG  C.  The reaction time varies from 5 or more hours at 190 DEG C. to 0.1 hour or more at 450 DEG  C.  The guanidine thiocyanate may be recovered from aqueous solution by cooling or evaporating to cause crystallization or by adding a water-miscible organic liquid, e.g. ethanol, to cause precipitation; if desired, the guanidine thiocyanate may be converted into a less soluble salt such as the picrate, carbonate, nitrate or phosphate by adding to the aqueous solution an amount of the corresponding ammonium or metal salt of the acid.  In examples, 0.49 moles. urea and 0.249 moles. carbon disulphide are heated in an autoclave and after the reaction is ended the vessel is vented, the reaction product dissolved in water and the guanidine thiocyanate is converted into the nitrate or citrate by adding to the solution the appropriate ammonium salt.ALSO:Ammonium thiocyanate is obtained as a by-product when urea and carbon disulphide are heated in a closed reaction zone at 190 DEG C to 450 DEG C to form guanidine thiocyanate (see Group IV(b)).  The reaction product comprising the mixed thiocyanates is worked up in conventional manner to separate the guanidine thiocyanate.

Title: Improvements in or relating to clutch release control for clicking machines
Inventor: HAAS EDGAR
IPC: F16H35/14
Filed: 1955-02-11
Abstract: 768,299. Refractive switches; snap action switches. SCHWABE, Inc., H. Feb. 11, 1955, No. 4176/55. Class 38(5) [Also in Group XXIV] A clutch release control mounted on the swinging cutting beam of a clicking machine, i.e., a machine cutting leather &c., comprises an upwardly projecting handle 30 which is round in horizontal section and has a clutch control lever 32 projecting radially and movable into or out of the body of the handle, and an electric switch beneath the handle for operation by the resulting movement, of the lever. The switch is formed by a contact 48, Fig. 6, on an arm 42 fast on a spindle 44 which is turned to engage the contact 48 with a contact 46. The spindle 44 is fast with a rocker 50, Figs. 3, 7 engaged by a roller 56 biased by a spring 58 in a lever 52 pivoted at 54. A pin 94 on the lever 52 engages a groove in a rod 88 biased upwardly by a spring 60 and engaged at its upper end by a cylindrical plunger 76. The plunger is in turn engaged by the heel 36 of the control lever 32, which is pivoted at 34. Spring biased pivoted detents 62, 64 co-operate with the rocker 50 and the lever 52 to produce a snap action of the switch. On first moving the control lever 32 from the position shown in Fig. 3, the plunger 76 and rod 88 are moved downwardly, but the detent 64 co-operates with the rocker 50 to prevent the latter from turning. As the rod 88 continues to move downwards with the movement of the control lever 32, the lever 52 turns and the roller 56 is moved inwards against the bias of the spring 58. Ultimately, the lever 52 engages the detent 64 to release it from engagement with the rocker 50, which is then snapped over to its new position. On releasing the clutch control lever 32, the spring 60 moves the rod 88 &c. upwardly to perform a similar series of operations and restore the position shown in Fig. 3. The cylindrical plunger 76 is provided at one end with a flat headed crew 98, so that its effective length may be adjusted. The handle 30 is held on the top plate, 84 of the cutting beam by a nut 82, which may be released in order that the handle can be turned about its vertical axis and secured in the position best suited to its operator.

Abstract: 437,235. Colour photography. HADDAN, P., 31, Bedford Street, Strand, London.- (Soc. Lumiere ; 82, Rue de Rivoli, Paris) Feb. 11, 1935, No. 4354. [Class 98 (ii)] [See also Group XXXVIII] Relates to films for the production of combined photographic sound records and kinematograph pictures in natural colours, the latter being obtained by means of a multi-colour irregular screen. According to the invention, the film is provided with a longitudinal sound track portion which is free from grains or coloured particles. In one way of carrying out the invention, varnish is applied to a wide film by means of rollers 2 which are spaced apart so that portions 4 of the film between the rollers, and the overhanging margins, are left unvarnished. Coloured particles are then applied so as to form an irregular multi-colour screen on the varnished portions, which are intended to receive the pictures. The film thus treated is sensitized and cut along the lines A-A, Fig. 2, to form several films of standard width as shown in section in Fig. 5, each having a screened pictureportion 6 and a narrow clear portion 5 on which the sound may be recorded. Modifications of details are described ; e.g. both marginal portions of each finished film may be devoid of . screen particles. Further alternativese consist in varnishing the whole width of the film and then either removing the coating along the sound track portion or shielding such portion when the particles are applied. Specification 335,899, [Class 40 (ii)], is referred to.
