Title: Improvements in or relating to photographic transfer processes
IPC: G03C11/12
Filed: 1920-12-22
Abstract: 177,255. Kent, F. W. Dec. 22, 1920. Plates, films, and papers, stripping.-In order to obtain, in a photographic transfer print, a more effective rendering of the subject, intensifying the shadows and throwing up the high lights, the print is made on a stripping medium which gives a matt or nearly matt surface to the contacting face of the film and the film is transferred with the matt surface uppermost, to a mount between which and the print there is produced a gelatinous transparent substratum of a reflecting or shiny character. The transfer is effected in such a way as to give optical contact between the film and the reflecting substratum. A transfer paper with a chrome alum stripping- medium, such as described in Specification 164,448, is used. In effecting the transfer, the damped and coated mount is laid upon a warm surface to prevent the coated gelatine setting prematurely and the transfer film is laid upon the gelatine surface without applying pressure or squeegeeing. The mount is then cooled to set the gelatine.

Title: Improvements in bevel gear wheels and the process of manufacturing the same
IPC: B23F5/20
Filed: 1935-12-31
Abstract: 469,992. Toothed gearing. KLINGELNBERG, G. A., KLINGELNBERG, W. H., and KLINGELNBERG, H. W., (trading as KLINGELNBERG SOHNE, W. F.). Dec. 31, 1935, No. 36088. Convention date, Jan. 12. [Class 80 (i)] [Also in Group XXII] A pair of bevel gears have oblique teeth cut so that when in mesh neither of the apices O<1>, O<11> of the pitch cones of the gears coincide with the point O of intersection of the gear axes. Gears cut in this way have a decreased area over which there is thrust slip between intermeshing tooth surfaces and vibration between the gears is reduced. In the usual spiral or oblique toothed bevel gear the spiral angle Qi varies from the small end to the larger end. Assuming a uniform peripheral force Pu over the length of a tooth, the normal force Pn in the case of a spiral gear increases from the small to the large end as shown in Fig. 1. In the dedendum portion of a driving tooth the sliding velocity is in the nature of a thrust between the engaging tooth surfaces while in the addendum portion the sliding produces a drag between the tooth surfaces, the change from thrust to drag occurring at points on the pitch cone. The thrusting action produces vibration between the engaging gears and according to the invention a higher sliding velocity at a part of the gear where the normal force Pn is least allowed for the addendum D of Fig. 5, the driving tooth and a lower for the dedendum portion E thereby reducing the thrusting action. In the case of bevel gears it is shown that the slip increases with decrease of spiral angle. Thus in Fig 1 there is less sliding between the tooth, profiles at the large end and the vibration effects are therefore low. Hence the profile is not modified at the point of largest spiral angle. In making gears according to the invention, the pinion 1 and gear 2 have pitch cone angles alpha- and #-respectively while the rolling cones from which the generating motions are derived have angles alpha# and ## with a common centre 9, a trace of the rolling plane being shown at A Ca. The tools are moved in an imaginary crown gear plane B Ca having a point Ca common with the rolling plane and located near the large end of a gear of the form shown in Fig. 1. The centre O<11> of the basic crown gear lies on the axis of the driven gear 2. By setting a generator of the surface cone of the work at an angle to the crown gear plane, the profile of the teeth may be modified in the manner shown in Fig. 8. Where the concave face of the gear is the driving face the surface generator is set, Fig. 6, so that it contacts the theoretical gear plane at the large end but is spaced therefrom at the small end.

Title: Improvements in and relating to the production of the thiocyanates and ferrocyanides of the alkali and alkaline earth metals and prussian blue
IPC: C01C3/12
Filed: 1932-12-20
Abstract: In the production of alkali metal and alkaline earth metal thiocyanates with the intermediate production of thiourea, by the reaction of sulphur or materials containing sulphur in the sulphidic condition with calcium cyanamide with the addition of lime and/or alkali salts, the reaction components are added to the reaction mixture from time to time in small proportions of the whole and in such relative proportions that a small excess of alkali, preferably as calcium sulphydrate, exists at each stage, the resultant solution being converted in known manner into the desired product.  The thiocyanates may be converted into alkali or alkaline earth ferrocyanides or into Prussian-blue in known manner.  The sulphides or sulph-hydrates of alkali or alkaline earth metals or used desulphidizing gas purification materials may be employed as the sulphur containing material.  According to an example, used desulphidizing gas containing material is agitated and heated with water and lime, calcium cyanamide being subsequently added.  Then in a succession of steps, further portions of gas purification material, calcium cyanamide and water or washing liquors are introduced, the addition of calcium cyanamide being slower than that of the gas purification material in order to maintain an excess of hydrosulphide.  Calcium thiocyanate is obtained.  If the water is replaced by a solution of an alkali salt, such as potassium sulphate or if syngenite is added, alkali thiocyanate is obtained.  If potassium sulphate, calcium cyanamide and gas purification material are reacted in certain proportions a solution of thiourea containing potassium thiosulphate results.  This may be freed from lime by treatment with flue gas or potassium carbonate, concentrated, and finally treated with additional lime and gaseous ammonium sulph-hydrate. The resulting potassium thiocyanate may be converted into potassium ferrocyanide by reaction with metallic iron.  The ferrocyanide may be converted into Prussian-blue.ALSO:In the production of thiourea as an intermediate step in the product of alkali or alkaline earth thiocyanates by the reaction of sulphur or materials containing sulphur in the sulphidic condition with calcium cyanamide with the addition of lime and/or alkali salts, the reaction components are added to the reaction from time to time in small proportions of the whole and in such relative proportions that a small excess of alkali, preferably as calcium sulphydrate, exists at each stage.  According to an example, potassium sulphate, calcium cyanamide, lime and gas purification material are reacted in the presence of water to produce a solution containing thiourea.

Title: Improvements relating to the formation of heat and sound insulating coatings
IPC: E04F21/12
Filed: 1930-12-01
Abstract: In the process of forming heat or sound insulating or waterproof coatings, particularly on steel panels, by spraying a fibrous material (with or without non-fibrous particles) and an adhesive simultaneously on to the surface, the fibrous material is supplied directly to the suction side of the fan in the form of a uniform suspension of small particles in air.  A solid ingredient of the adhesive may be mixed with the fibrous material while a liquid ingredient is sprayed simultaneously on to the surface. Fibrous materials specified are asbestos, animal hair, wool and cotton; adhesives specified are sodium silicate, magnesite and magnesium chloride solution, and Portland cement and water. Waterproofing coatings may be formed by spraying simultaneously asbestos and bituminous materials.  As shown, asbestos fibre is fed at A between moving plates 21, 22 with the hopper 1, and is opened by the band 2, 3 which delivers it to a hopper 4 leading direct to the suction inlet of a fan 5 having only a few blades spaced relatively far apart.  A low-speed brush 7 regulates the supply to the hopper 4 and a high-speed brush 6 detaches and opens the fibre.  The fan delivers through a hose 8 to a nozzle 9 adjacent to a spraying gun 10.  The plates 21, 22 are pivoted at 23, 24, connected by a link 32, and driven from an eccentric 26 by a rocking lever 29 and link 30.  The fan, the band, the brushes, and the moving plates are driven by an electric motor 11 through belts.  The band 2 is driven from the spur gear 8, Fig. 3, keyed on a hollow shaft 20.  The belt 17 drives a pulley 16, <PICT:0368368/III/1> <PICT:0368368/III/2> Fig. 3, with clutch face 18 which is normally engaged by a disc 19 on the shaft 20 under the action of a spring 34.  One end of the spring is secured to a collar 33 on the hollow shaft 20, and the other end to a flanged sleeve 15 which normally rotates with the shaft.  To disengage the clutch and stop the supply of fibre, a brake-band 39 on the sleeve 15 is tightened by Bowden mechanism from a lever 13 on or close to the spraying gun.  The sleeve 15 is thus held against rotation, and a pin 35 on the shaft 20 engaging an inclined slot 36 in the sleeve 15 moves the shaft endwise.  The supply of adhesive may be cut off at the same time by a valve trigger 12 on the spray gun.  A separate machine for disintegrating rock asbestos may supply the disintegrated particles direct to the fan or may be used in series with the machine shown.  The fibrous material may be fed to the fan by hand in the form of a uniform suspension.

[Also in Division H2] In a circuit for detecting faulty operation of a pulse system, the potentials on a plurality of conductors are added by means of an impedance connected between each conductor and a common point, a voltage comparator being connected between the common point and a point of reference potential, the voltage comparator providing an output only when the potentials on the conductors are incorrect. Fig. 1 shows a signal stepping chain in which gas-filled tubes 1-7 provide pulses of amplitude E successively on lines 21-27 respectively, ignition and extinguishing pulses being applied respectively to terminals 11, 12. When the system is operating correctly, a pulse E is present only on one of the lines 21-27 at any time. Lines 21-27 are connected by resistors R of equal value to a point 30 which normally attains a potential of E/6. When the gate 32 is opened, this potential is compared with the reference potential at point 35 so that an indication of incorrect operation is provided at 311. The gate 32 is controlled by extinguishing pulses delayed at 36. In Fig. 5, one conductor of each section is maintained at one potential and all others at another potential. The reference potential is provided by the potential divider formed by the left-hand resistors R and resistor 50. Fig. 6 comprises two fault detector systems, the outputs of which are fed to an amplifier 65. Resistors R may be replaced by capacitors or inductors.
