Title: Improvements in or relating to shoe engaging pads for shoe presses
IPC: A43D25/12
Filed: 1957-02-04
Abstract: 893,473. Shoe bottom presses. RALPHS, G. C., and RALPHS, G. T. April 24, 1958 [Feb. 4, 1957], No. 3739/57. Class 17(1) An inflatable shoe-bottom engaging pad for pressing soles and heel flaps to shoes has two transverse lines of flexure dividing it into toeward, waist and heelward sections and is supported by means permitting relative angular adjustment of the sections to suit shoes with different heel heights. The pad consists of a bag formed from two flexible sheets joined at their edges and clamped marginally by stiffeners divided at each line of flexure, with an inlet tube 53 to permit fluid to be forced between them. The line of flexure between the waist and heel is defined by pivot pins 28 and the angle the heelward section makes with the vertical can be adjusted and held by a slidable strap 35 and a clamping screw 37. The setting of the toeward and waist sections 15 and 16 of the pad can be varied by lowering and raising the rear end of section 15 by means a link 30 operated by a hand wheel 32, the forward part of section 15 sliding and pivoting on post 18. To avoid undesired stresses on the heel of the shoe during application of the heel flap, the back of the heel is engaged by a clamp 54 pivotally mounted for permissive vertical movement on a carrier lever 59 which may be operated manually or pneumatically in timed relationship with the application of shoe clamp jacks, 51, 52. Specifications 747,854 and 879,711 are referred to.
Patent GB-580013-A (GB)
Title: Improvements in or relating to filter plants with automatic wash-out
IPC: B01D33/00
Filed: 1944-02-29
Abstract: 580,013. Filters. BENDEL, H., and JONNERET, F. Feb. 29, 1944, No. 3764. Convention date, Sept. 4, 1943. [Class 46] A sand bed filtering plant comprises a closed vessel with pneumatically actuated control means (a three-or more-way valve) whereby raw water may be admitted to the vessel or soiled cleaning water discharged therefrom and the cleaning of the sand is periodically effected automatically by circulation with a current of compressed air and filtered water when the filter becomes clogged, the control means (valve) being automatically changed over at the beginning and end of the cleaning period. As shown raw water from a pipe 1 enters a closed vessel 3 through a port 47 of a slide valve 41 when the latter is in its bottom position and the water passes through a sand bed 2 with sloping bottom 4 into a collecting bell 14 and so through a pipe 17 past a non-return valve 50 to the filtered water discharge pipe 21. As the sand bed becomes clogged the water in the closed vessel rises above the normal level 5 and a manometer device 33 is eventually actuated by the water pressure to set into operation an air compressor 26 whereby the slide valve 41 is at once moved to its top position by an air-line connection 30 to the underside of the slide-valve piston face 44. With the slide-valve in the upper position the port 47 connects the vessel 3 to a waste discharge pipe 27 whereby the overlying water passes away and the level falls to the entrance level of the discharge pipe entrance end 29a. Since this level is lower than that of the filtered water tank a ballasted-float valve 10 is lifted from the top of a tube 8 and the pressure conditions now allow compressed air to rise in the tube 8 to give an air-lift pumping action to cause the sand to be circulated from the sloping bottom 4 and washed with filtered water coming from a throttled bye-pass 51. This action continues till a timing device 34 stops the compressor 26 whereupon the slide valve 41 returns to its bottom position and normal filtering operation is resumed. Adjustable stops for the slide valve such as 48 allow regulation of its through-flow. A non-return valve 49 prevents entry of water into the compressor.

Title: Improvements in means and method for preparing fish for filleting
IPC: A22C25/17
Filed: 1936-02-07
Abstract: 466,674. Dressing fish. HUNT, W. H. Feb. 7, 1936, No. 3804. Convention date, Jan. 2. [Class 28 (ii)] A fish-dressing mach. ine comprises a pair of rotary disc knives 61, arranged to cut a thin band of flesh from the back of a fish which is conveyed past and above the knives, the dorsal fins and associated knuckles being thus removed. The knives 61 are driven from shafts 51 through universal couplings 57. The bearings 59 are adjustable to vary the inclinations of the knives and are locked by bolts 60. The housings 44 for the shafts 51 are slidably arranged in the standards 40, and are reciprocated so that the tail ends of the fishes may pass between the separated knives 61, which are then brought together to effect the cuts along the backs of the fishes. The inside faces of the knives carry protuberances 62 which engage the band of flesh and remove it from the fish. The reciprocations of the housings 44 are effected by rollers 47, which engage cams 48 carried on a member 49 mounted on rods 50 which are reciprocated by cam means. The spacing of the knives 61 is controlled by adjustable stops 20a. The machine is intended to effect a preliminary removal of dorsal fins before further filleting treatment as described in Specification 452,688. The headed fishes are pushed, by hand or mechanically, tail first and back down along the trough 23 and between the gates 24 which are pivoted on pins 25, and are normally retained closed by springs 26. The tail of each fish is then gripped between spiked plates 15 on cam actuated rods 12 slidable in blocks 8 carried by the conveyer chains 7. The fish is pulled over ' a back fin straightener 33, as described in Specification 452,688, and is held for presentation to the knives 61 by a V-shaped presser plate 29 carried on pivoted arms 27, Fig. 1. After passing the knives 61 the fishes are moved along a trough 100 to further filleting devices. The blocks 8 have side extensions 8a which are attached to the chains 7, the extensions being spaced from the main portion of the block to form guide ways or passages for the stationary plates 9. This arrangement ensures a straight line pulling motion of the grippers 15 which are actuated transversely by rollers 13, 14 engaging cam rails 17a, 18, 19, the rollers 13 applying the gripping thrust being in line with the grippers 15. The height of the back fin straightener is adjusted by a shaft 35 angularly adjusted by a handle 27, Fig. 3, and carrying an eccentric pin 38 which engages a hole in a yoke 34 joining the two parts of the fin straightener. Specification 454,500 also is referred to.

IPC: B01J8/32
Filed: 1964-01-29
Abstract: Particles of pigmentary titanium dioxide and of an inert refractory material (of larger particle size than the TiO2) in a chlorine-containing suspension (resulting from the manufacture of TiO2 by the vapour-phase oxidation of TiCl4) are separated from each other by introducing the suspension into a vessel to form a bed of particulate material, passing an inert gas (e.g. N2) upwardly through the bed which, due to the rate of flow of the gas and the internal shape and dimensions of the vessel, becomes stratified into an upper fluidized layer consisting principally of TiO2 and a lower fluidized, partly fluidized or non-fluidized layer consisting principally of the particulate refractory material, and withdrawing particles from the two layers.  The inert particulate refractory material may consist of particles of zircon, alumina, titanium dioxide or, preferably, silica sand.  Different forms of separating apparatus (see Division B2) are described.

Title: Process for dyeing of suede leather
IPC: D06P3/32
Filed: 1943-03-10
Abstract: Azo dyes, forming on the material.-A process for the production of an azo dye on suede leather comprises the steps of applying thereto a diazo component in alkaline solution, adding a strong mineral acid in one or more stages to produce a pH sufficiently acid to exhaust the component on the leather and employing the same acid in conjunction with a nitrite to form the nitrous acid for the diazotization.  The deleterious effect upon the subsequently added coupling component of the excess of nitrous acid remaining after the diazotization may be eliminated by addition to the bath, prior to the addition of the coupling component thereto, of a reagent capable of neutralizing or destroying the nitrous acid.  Specified reagents for this purpose are ammonium hydroxide, primary aliphatic amines or carboxylic acid amides, urea, sulphamic acid and ammonium sulphamate.  The diazo component is advantageously an aminoazo dyestuff such as Developed black BH, Diazamine blue BR, Diazo black RS, Diazine brown M, Diazine dark green G, Diazo fast yellow 2G and Direct green G.  Specified coupling components are b -naphthol, p-aminodiphenylamine, 2 : 8 : 6-aminonaphtholsulphonic acid, N - ethyl - b  - naphthylamine, m - phenylenediamine, m - toluylenediamine, resorcinol, 3-nitro-4 : 41-diaminodiphenyl, 1-phenyl-3-methyl-5-pyrazolone, 2 : 3-hydroxynaphthoic acid and the benzidide and p-phenetidide of acetoacetic acid.  In examples: (1) chrome-tanned calfskins are treated in a rotary drum with an aqueous solution at 55 DEG  F. containing Developed black BH, Direct green G, ammonia and soda ash, hydrochloric acid is added, followed by an aqueous solution of sodium nitrite run in during 20 minutes, whereafter an aqueous solution of ammonium sulphamate is run in, followed by an ammoniacal solution of m-toluylenediamine, the skins being then washed and fat-liquored with a solution containing sulphonated cod liver oil; (2) the coupling component in (1) is replaced by the p-phenetidide of acetoacetic acid applied with the aminoazo dyestuff, the step of adding the ammonium sulphamate solution being omitted; (3) and (4), tanned kid skins are treated in a rotary drum with an aqueous solution cooled to 70 DEG F. containing Developed black BH, Direct green G, ammonia and soda ash, hydrochloric acid is added, followed by sodium nitrite, whereafter (3) aqueous ammonium hydroxide; (4) an aqueous solution of methylamine is added to neutralise or destroy the excess nitrous acid, followed by an ammoniacal solution of m-toluylenediamine, the skins being then washed and fat-liquored as in (1).

Title: Improvements in or relating to safety devices for hydraulic circuits
IPC: F16K17/30
Filed: 1962-02-01
Abstract: 985,187. Valves. R. L. A. GILLAIN. Feb. 1, 1962 [Feb. 7, 1961], No. 3912/62. Heading F2V. A safety valve for hydraulic circuits which closes in the event of a sudden drop in pressure in a utilization circuit comprises a cylinder 1, 11 of two diameters housing a piston 8 of two diameters, the piston having a through passageway 16. The piston is provided with a blind bore extension having ports 17, 18 controlled by a spring-loaded lip seal 4. The cylinder assembly has an inlet 21 for connection to a fluid supply and an outlet 22 for connection to the utilization circuit. A removable seat 12 is provided for co-operation with the passage-16. To set the valve, the seat is unscrewed and fluid pressure from the inlet moves the piston to the right to abut a bush 13 and then moves the seal 4 to allow flow through the ports 17, 18 and passage 16 to the outlet, grooves 20 allow flow past the bush. As the pressure in the outlet rises, the piston 8 is returned to the left. When the supply ceases the seal 4 moves to the left and return flow takes place by deformation of the outer lip of seal 4. The seat 12 is then screwed into the cylinder. Supply and exhaust of fluid to the appliance takes place with little or no movement of the piston but in the event of a sudden drop in outlet pressure due to failure of the appliance, the piston moves to the right and the seat 12 closes the passage 16 thus cutting out the circuit to the appliance.

Title: Improvements relating to the production of isoparaffins
IPC: C07C5/27
Filed: 1940-03-08
Abstract: 541,106. Hydrocarbons. ANGLO-IRANIAN OIL CO., Ltd., FAWCETT, E. W. M., and NARRACOTT, E. S. March 8, 1940, Nos. 4405/40 and 3266/41. [Class 2 (iii)] Isoparaffins are prepared by contacting the corresponding normal paraffin, in admixture with a hydrogen halide, with a catalyst consisting of alumina alone or mixed with inert substances. The re-action may take place in a batch or continuously and is preferably effected at a temperature of 100-300‹ C. and with exclusion of moisture ; it may be effected in vapour or liquid phase and super-atmospheric pressure may be employed. The catalyst may be in the form of alumina gel or a natural alumina such as bauxite or alumina deposited upon a carrier, e.g. by soaking silica gel with a solution of aluminium sulphate and washing the product with water. The proportion of hydrogen halide employed depends on the pressure, being less as the pressure is increased ; at atmospheric pressure hydrogen chloride may be present in 15-30 per cent. by weight of the hydrocarbon feed. The hydrogen halide is recovered either by fractionation of the re-action product or by scrubbing it with caustic soda solution or milk of lime. The isoparaffins obtained are directly re-acted with an olefine to produce a fuel of high octane number. Examples are given of the conversion of n-butane into isobutane in the presence of hydrogen chloride and of alumina gel or alumina absorbed on silica gel as catalyst.
