Filed: 1951-08-31
Abstract: 718,716. Colour photography. TRU COLOUR FILM, Ltd., and BURT, G. H. Aug. 29, 1952 [Aug. 31, 1951], No. 20591/51. Class 98(2) A positive latent silver image in a colloid layer is developed in a black and white developer, bleached, and treated with a single aqueous solution containing an acid dyestuff, a thioamide or selenoamide, and a soluble halide or other substance to reduce the solubility of the silver halide or halides present in the bleached image, the result of this being a complex image from which the final colour image is transferred to a permanent base. The reduction of solubility of silver halide during complex formation, by which factor the process differs from that of Specification 466,710, avoids diffusion of the silver halide and leads to retention of dye in depth therewith and in formation such that the dye is retained in situ with the silver halide during washing of the complex image but is transferable by contact with the mordant-carrying permanent base. After black and white development and fixing the silver image may be bleached in a solution of potassium permanganate and hydrochloric acid, treated with sodium bisulphite and potassium bromide to convert silver chloride to silver bromide and then in a solution containing potassium bromide, sodium acid phosphate and thiourea together with a specified red, yellow or blue acid dye, and washed in still or gently flowing water to clear non-image portions of colour. To effect trans-  fer the sheet bearing the complex image is treated with a solution containing thiourea and acetic acid and then maintained in contact as with a gelatinecoated paper which has been mordanted with aluminium hydroxide for 5 to 15 minutes. Specification 547,722 also is referred to.

Abstract: 1335331 Crash restraint bags GENERAL MOTORS CORP 4 May 1972 [12 May 1971] 20840/72 Addition to 1326671 Heading B7B A one-way valve which permits the flow of fluid under pressure into a crash restraint bag 28, but prevents the reverse flow of fluid is provided adjacent a diffuser 56 forming part of an occupant restraint system 24. The system 24 is mounted within an instrument panel 22 of a vehicle and includes torso bag 26 and a knee bag 28. A reservoir 32 containing air or nitrogen under pressure is closed by a valve assembly 34 and a combined detonator and diaphragm assembly 38 having a rupturable diaphragm 40 and detonators 42. The assembly 34 senses retardation forces applied to the vehicle and connects wires 46 to an electrical source when the forces exceed a predetermined magnitude. The diaphragm 40 is ruptured to release the pressurized contents of the vessel 30. The diffuser 56 is provided with a row of slots (60), Fig. 3 (not shown), and slots 58, Fig. 2. The bag 26 is inflated from the slots 58. The bag 28 which may be of nylon coated with synthetic polyester fibre has upper and lower walls (78, 80), Fig. 3 (not shown). An inflatable sleeve 86 extends from the lower wall 80, Fig. 6, of the bag 28, the sleeve 86 having first and second plies 90, 92 stitched together. A slit (100), Fig. 4 (not shown), communicates with a slit 88, Fig. 6. Brackets 104, 106 enclose the slit 88 and hold the surrounding portion flat. Upon rupture of the diaphragm 40, Fig. 2, fluid flows through the slots 58 and (60) to open the slits 88 and (100) and infllate the sleeve 86. When the pressure within the bag 28 equals or exceeds the pressure in the diffuser 56, the sleeve 86 is deflated to prevent the return of fluid under pressure to the diffuser. Similarly, pressure in the bag 28 closes the slit 88. In certain circumstances, the sleeve 86 may be dispensed with.

Abstract: 645,408. Photo-electric indicating systems. BENDIX AVIATION CORPORATION. July 31, 1947, No. 20845. Convention date, Sept. 16, 1946. [Class 40 (iii)] To indicate to the pilot of an aircraft when the axis of a concealed automatic pilot gyroscope is in its vertical position, light is reflected by a mirror carried on the axis of the gyro or on an associated erecting mechanism of the type described in U.S.A. Specification 2,159,118, which rotates at a constant but reduced speed, to a photo-cell only when the gyro is vertical. As shown, a gyro 15 mounted for three degrees of freedom is provided with an erecting mechanism 18 of the type previously mentioned which rotates at a speed which is substantially constant but considerably lower than that of the gyro axis. A mirror 23 carried by the erecting mechanism reflects light from a shielded source 24 to a photo-cell 27 when the gyro axis is vertical. The resulting current increase in the photo-cell is used to reduce the negative bias on an A.C. fed gas-filled relay 34 which fires, the resulting increase in anode current developing a voltage across a neon tube 51 which thus flashes intermittently. In a form of the invention in which the mirror is mounted on the gyro axis proper the photo output is fed through a band-pass filter tuned to rotor frequency so that the gyro must be vertical and substantially at the correct speed before the lamp can flash.

IPC: D06J1/06
Filed: 1928-07-18
Abstract: 307,414. Ezbelent Fils. March 7, 1928, [Convention date]. Pleating.-In pleating-machines, the change of amplitude. of the movement of the knife carrier takes place at the end of the rear movement of the knives away from the pleat-setting drums. The means for reciprocating the knife carrier is connected with means for rotating the pleating drums. As shown, a knife carrier 1, with knives 2, 3 is mounted on a slide 5, and reciprocated by links 10, through the medium of a cam 14, cam slot 13, and roller 12. The pleat-setting rollers 8, 9 are operated, when the knives move forwards, by means of a lever 16, which is connected at one end with the slide 5 and at the other with a lever 17 pivoted at 18. The lever 17 is adjustably connected to a link 19, which is connected at 20 to a sector 21 pivoted on the axle of the lower drum and operating the drum by means of a, pawl 22 and ratchet wheel 23. The ratchet wheel is keyed to the axle of the drum. The width of the pleats is determined, as is well known, by the position of a pivot axle 11 on the link 10, and this pivot is automatically varied by a cam 28 and roller 26. In the known machines, this takes place at the end of the forward stroke of the knives, but in the present invention it takes place at the end of the rear stroke. At the end of the rear stroke, a surface 32 on the cam 14 engages the tail 31 of the pawl 22 holding it out of operation to prevent the drive of the ratchet wheel when the stroke is being changed. This ensures that the covering part of a pleat always corresponds to the pleat already made. In a modification, the tail of the ratchet pawl is moved into the inoperative position by a roller on a pivoted hand-operated bell crank lever.

Title: Improvements in the manufacture of soap bars or tablets
IPC: C11D13/12
Filed: 1945-08-14
Abstract: In making household or laundry soaps, as distinct from toilet soaps, in bar or tablet form by rapidly chilling molten soap of about 60-65 per cent. total fatty matter (briefly called 63 per cent. soap) so as to solidify the soap within a few seconds, and thereafter, without subjecting it to a drying operation, plodding the solidified soap, one or more steps are taken to increase the degree to which the soap mass is compacted during plodding.  Such steps may be taken prior to or during the plodding operation.  The molten soap may be prepared by any soapmaking process particularly by the fitting or the curd processes.  The rapid chilling may be effected by passing the molten soap over a cooling drum, by spraying the molten soap into unheated air, or by spraying the molten soap on to a cooled surface.  The additional steps may comprise working the solidified soap prior to the plodding, such as by milling, or by a refining treatment such as described in Specification 380,820; plodding at sub-atmospheric pressure; or passing the extruded soap bar into an extension tube added to the nozzle of the plodder, the increased resistance of which serves to build up the pressure in the plodder.  The plodding is preferably effected under de-aerating conditions, such as in the presence of carbon dioxide.  Full working details are given in a number of examples of the process using specified known fats and fatty oil mixtures to prepare the starting molten soap. Specification 20916/07, [Class 91], also is referred to.

Abstract: 664,671. One-way vehicle brakes. CHRYSLER CORPORATION. Aug. 1, 1947 [March 1, 1946], No. 20962/47. Class 80 (ii). [Also in Groups XXXI and XXXIV] A one-way brake mechanism for preventing a vehicle from running back, when parked or stopped on an incline, is arranged to be operatively associated with the driving side of a clutch located between the engine and gearbox. The one-way brake device 54, which as shown in Fig. 3, is of the known type comprising balls 66 wedging on inclined faces, is such that the outer surfaces of the balls bear against a member 55 rigid with the gearbox frame and the inner faces bear against inclined recesses on a sleeve 53, which is rotatable on gearbox input shaft 20, and is coupled by plates 52 and 24 and bolts 25 to the plate 22 forming the driving side of the friction clutch 23. Providing the gear train is engaged, the vehicle is prevented from running back so long as the clutch 23 is also engaged and the device prevents the movement that might take place, if no brake were fitted, due to the slip between the driving and driven members of a fluid coupling 14, the inclusion of which is made the subject of Specification 664,750, [Group XXXIV]. Undesired forward motion will be prevented in the same way by setting the gearbox lever for reverse drive.

Abstract: 144,338. Carey, E. S. Dec. 16, 1918. Centrifugal speed indicators with recording- apparatus.-In apparatus for recording the speed of a moving part of a machine and the direction of revolution, a hollow member A carrying the recording parts, is rotated at a constant speed through gearing D, D<1>, and E, E<1> by a slowspeed motor or other mechanism, and a governor H is driven by the machine whose speed is to be recorded either directly or through a motor K and generator L. As the speed varies, the governor H, which is rotatably connected by a collar F<2> with a piston rod F<1>, reciprocates a piston F and causes mercury in the member A to be forced into or withdrawn from the barrel or radial arm A' and thereby moves the plunger G radially against the action of springs G<1>. To the plunger G is attached a marking-device M, N which is arranged to move in operative relation to a recorddisk. In order to distinguish in which direction the machine has been running, the marking-device as shown in Fig. 2 comprises two arms M disposed at an angle to one another and secured together by a bar R to the end of the plunger G and bv a curved bar S which bears on the recorddisk. The markers N are of different colour and by the rotation of the radial arm A<1> in one direction or the other, one or other of the markers N is brought into engagement with the record-disk and traces a curve of different colour. When a blank disk is provided, datum lines may be drawn thereon by providing the radial arm A<1> with an extension or additional arm P adjustable on the arm A<1> and carrying a number of markers Q adjustably mounted thereon. Instead of providing a fixed record-disk the radial arm may be held stationary by a thumb-screw T and a recordstrip fed along at right-angles to the arm or the radial arm may be allowed to rotate and the record-slip fed intermittently after each record or desired period so as to expose a fresh surface to the marking-device.

Filed: 1950-08-25
Abstract: The invention comprises compounds of the general formula <FORM:0674594/IV (b)/1> (wherein R1 represents a hydroxyalkyl, carboxyalkyl, carbamidoalkyl, aliphatic acyl or aroyl radical, the last two of which may be substituted by an NH2 group and all of which contain not more than 12 carbon atoms), and the manufacture thereof by (a) the action of nitrous acid on a compound of the general formula <FORM:0674594/IV (b)/2> (wherein R1 is as before except that the amino group, if any, therein is formed or introduced subsequently by conversion or replacement of a substituent convertible thereto or replaceable thereby present therein in the starting material), or (b) the condensation of 5-amino-7-hydroxy-1-v-triazolo-(d)-pyrimidine with a compound R1-OH or a reactive ester thereof, R1 being as in (a).  The nitrous acid in (a) may be in the form of a salt or ester (e.g. an alkyl nitrite), in which case the reaction is preferably carried out in an acid medium.  The condensation in (b) is preferably effected in the presence of a condensing agent, e.g. if a hydrogen halide is liberated, an alkali salt of a weak acid.  The products are useful as therapeutic agents or intermediates therefor.  In examples, the following compounds are treated with sodium nitrite in the presence of acid: (1) 2-carboxymethylamino - 4 : 5 - diamino - 6 - hydroxypyrimidine; (2) 2 - carbamidomethylamino - 4 : 5 - diamino - 6 - hydroxypyrimidine; (3) 2-hydroxymethylamino-4 : 5-diamino-6-hydroxypyrimidine; (4) 2 - (41 - nitrobenzoyl) - amino - 4 : 5 - diamino - 6-hydroxypyrimidine (the nitro group being subsequently reduced with hydrogen in the presence of pallidinized carbon); (5) 2-chloroacetylamino - 4 : 5 - diamino - 6 - hydroxypyrimidine (the chlorine atom being subsequently replaced by NH2 by the action of concentrated aqueous ammonia).  In further examples, 5-amino-7-hydroxy-1-v-triazolo-(d)-pyrimidine is reacted in the presence of sodium acetate with (6) chloracetic acid, and (7) chloracetamide.

Abstract: 1,043,105. Automatic exchange systems. SIEMENS & HALSKE A.G. May 22, 1964 [May 22, 1963]. No. 21180/64. Heading H4K. In a system which comprises a plurality of telephone channels and a common signal path which passes signals characteristic of the identity of the channel over which it is desired to set-up a call, reception of the identification signal at a called station is acknowledged to the caller by reverting a signal over the chosen channel whereby reception of this signal confirms that the chosen channel is fault free and initiates release of the common path. The channels may be two- or four-wire interchange junctions utilizing voice or carrier transmission or they may be radio channels. The identification signals may be V.F. or pulsed D.C. signals. If reception of the acknowledgment signal is unduly delayed an alarm signal is given. In the exchange system shown in Fig. 1, the number of a called party, e.g. TnC, which has been requested by a calling party, e.g. TnA, is recorded in a register RA associated with an idle junction La which has been selected by group selector WA. The register seizes a transmitter SA and so causes the identity of the chosen junction to be transmitted over the common path Sa to a receiver EB at the tandem exchange B. The appropriate register RB is then seized and an acknowledgment signal is reverted over La. This signal releases Sa and initiates the transmission of sufficient digits by RA to RB and EB via La as to allow selector WB to be set to an idle junction Lb. Similarly transmitter SB then identifies this junction to exchange C whereafter the remainder of the digits are transmitted from RA to RC and EC so as to allow the connection to be completed. Signals may be transmitted over Sa and Sb in one or both directions. Arrangements may be made for preventing the transmission of any voice signals from TrA until the connection is completely set up whereby the usual V.F. guard circuits need not be provided. Guard circuits are of course not required at all in the signal paths. The normally required junction-relay-sets may. be incorporated solely in the signal paths (Fig. 2, not shown).
