Title: Improvements in apparatus for making caskets and like hollow articles by galvanoplastic process
IPC: C25D1/00
Filed: 1928-09-13
Abstract: 322,551. Rosenqvist, G. Sept. 13, 1928. Moulds; supporting electrodes; preparing surfaces. - In an electrolytic process for making hollow articles, more particularly burial caskets or receptacles, perforated containers for scrap-metal are placed within, and adjacent to the surface of, a sectional mould of the shape and dimensions of the article to be formed, and an electrolytic solution is supplied to the interior of the mould to submerge the perforated scrap - containers which form the anodes, the receiving surface of the mould comprising the cathode. As shown in Fig. 2, the bottom 8, sides 7, and side extensions 9 of the mould are provided with lugs 10 to receive clamping-bolts 11, similar means being provided for the attachment of the end pieces. Notches 12 - 15 are provided in the walls of the mould to receive solid metal inserts which constitute the handles, hinge-pieces, rim, &c. of the finished article and have a bright surface upon which the metal forming the casket is deposited. To ensure an even deposition of the metal in the vicinity of the inserts, the joints between their exposed surfaces and that of the mould are filled or bridged by powdered bronze or other suitable material shaken in lacquer. The portions of the anodes adjacent to sharp inwardly-projecting portions 36, Fig. 7, of the mould are covered with isolating sections 37 of lead or other suitable material which cover the perforations in the containers and secure the requisite current density to prevent short-circuiting between anode and cathode. The mould may be placed upon supports 17 extending across a vat 18 containing electrolyte, and a pump 20 pumps the liquid through pipes 19 into the mould, from whence it is returned to the vat 18 by an overflow pipe 21. Alternatively, the mould may be placed on the floor, adjacent to the vat 18. A number of anodes 22 disposed side by side within the mould may be supported by wooden frames 25 slidably mounted on cross-beams 26 to enable them to be brought together to facilitate removal from the mould. The perforated scrap-containers forming the anodes are made of lead and are of the same general contour as the matrix of the mould. Terminal rods 29 inserted into the scrap metal are connected to supply leads 31, and leads 33 are connected to a terminal 32 on the mould.

Title: Process for colour photography
IPC: G03C7/30
Filed: 1937-05-10
Abstract: 501,001. Colour photography; photographic developing processes. KODAK, Ltd. May 10, 1937, No. 26470/38. Convention date, May 9, 1936. Divided out of 500,826. [Class 98 (ii)] Process of producing colour-developed reversed images in a three-layer photographic element, whose upper layer is not specially colour sensitized and which contains a colour sensitizer in the middle layer which is resistant to the action of photographic developing baths and of mild silver-oxidizing baths and a yellow filter dyestuff in the upper layer or between the upper layer and the middle layer, consists in developing the first latent images to silver, then removing the silver without destruction of the yellow filter dyestuff, then exposing the reversed silver halide image in the middle layer only by means of light of a colour to which it is selectively sensitized from either side, and colour developing it, then exposing the reversed silver halide image in the upper layer by means of blue light from the top, and colour developing it, and finally exposing and colour developing the reversed silver halide image in the lower layer. The middle layer may be sensitive to red and orange by using for sensitizer 4 : 4<1>-dichloro-2 : 2<1> : 8- triethylthiacarbocyainine chloride as described in Specification 501,003. The residual silver halide may be converted in one or more layers to silver chloride in a fine state of subdivision as described in Specification 501,003. In order 'to avoid the effect of local under-exposure in the lower layers all the layers are first saturated with developing agent in high concentration and are then treated with weak alkali to effect development. Alternatively a concentrated developing solution is allowed to diffuse into all the layers at as low a temperature as it is possible to employ without alteration in composition of the solution and the development process started or accelerated by warming the layers to room temperature or above.

Title: Improvements in curing of polyepoxides
IPC: C08G59/68
Filed: 1957-08-22
Abstract: Compositions based on a polyepoxide having a 1, 2-epoxy equivalency greater than one and a weight per epoxide group below 2,500 are cured by reaction with a neutral quaternary ammonium salt of a strong acid. Suitable salts are benzyltrimethyl or triethyl, ammonium chloride, benzyltrimethyl ammonium phosphate, trimethylbenzyl ammonium sulphate, tripropyl or tributyl benzyl ammonium chloride, cetyl trimethylammonium chloride, octadecyl trimethyl ammoniumchloride, tolyl trimethylammonium chloride, octyl trimethylammonium bromide, ethylene bis (trimethylammonium bromide) and ethyl pyridine chloride. Ion exchange resins containing residues of quaternary ammonium salts of strong acids are also suitable.  Suitable polyepoxides are glycidyl polyethers, and epoxidised esters of unsaturated fatty acids.  Curing is generally effected at a temperature between 90 DEG C. and 200 DEG C.  Part of the salt may be replaced by a polyhydric phenol, a polybasic acid anhydride or a primary or secondary amine. Lists of these conventional curing agents are given in the Specification.  Their action is accelerated by the quaternary ammonium salt which is used to the extent of 0,1 to 10% by weight of the resin in the modification of the invention.  Among the polyhydric phenols listed are phenol-aldehyde condensates.  Several examples give detailed preparations of epoxy resins.  Examples 2-4 measure the gel times of heated glycidyl ethers of polyphenols with various quaternary ammonium compound.  Example 5 describes a casting resin prepared from a glycidyl ether resin and benzyl trimethylammonium chloride.  Examples 6, 7, 9 describe curing of polyglycidyl ethers with a polyphenol and a neutral quaternary ammonium salt or accelerator.  In Examples 8, 10 a phenol-aldehyde condensate is used as the polyphenol.  Examples 14-18 describe the curing of epoxy resins with acid anhydrides and neutral quaternary ammonium salts as accelerators.  There are also several examples describing the curing of epoxy resins with amine hardeners and quarternary ammonium salts as accelerators.  The compositions of the invention may be used for encapsulating, laminating, coating, potting, casting or as adhesives. They may be compression or extrusion moulded and may be formed into sheets from which articles such as washers can be cut.  They may be blended with conventional additives, e.g. fillers, plasticizers, colouring materials or extenders.  Specification 679,536 and U.S.A. Specifications 2,467,171, 2,485,160, 2,581,464, 2,582, 985, 2,615,007, 2,615,008 and 2,698,315 are referred to.

Title: Improvements in or relating to automatic firearms
IPC: F41A5/18
Filed: 1945-10-11
Abstract: 599,952. Automatic firearms. BREVETS AERO-MECANIQUES SOC. ANON. Oct. 11, 1945, No. 26567. Convention date, Oct. 27, 1944. [Class 92 (ii)] The release mechanism for the locking mechanism of the breech-block of a firearm is effected by an element 16 carried by the breech casing, and the rod is actuated by an element such as member 13 carried by the barrel 10 and acted upon by gases from the barrel, the elements acting on one another by a pushing action, but being such that when at rest they do not prevent rotation of the barrel about its longitudinal axis relatively to the breech casing 11. In the construction shown, a single member 13 is guided at 14 and 15 on the barrel, the rear end of the member extending to the rear at least as far as the rear face of the guide 15; by this means the element 16 cannot enter the guide and thus prevent rotation of the barrel when the latter is to be removed. In a modification, a single port from the barrel is fed to a pair of members 13 symmetrically arranged with respect to the barrel axis and each co-operating with a separate rod 16. The Specification as open to inspection under Sect. 91 describes also a construction, Fig. 2 (Cancelled), in which two pistons are arranged symmetrically with respect to the barrel, the cylinders as shown being formed in the body of the barrel. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a method of and apparatus for measuring the geometry of road surfaces
IPC: G01B17/06
Filed: 1963-07-04
Abstract: 1,018,103. Ultrasonic distance-measuring devices. HOESCH A.G. July 4, 1963 [July 7, 1962], No. 26598/63. Heading H4D. A device for measuring the unevenness of road surfaces with respect to a theoretical smooth surface line comprises a loud-speaker 3 fitted on to a vehicle which emits continuous acoustic vibrations perpendicular to the road surface and a microphone 4 located adjacent the loudspeaker to receive the reflected vibrations, the evaluation of the distance between the vehicle and the surface of the road being carried out by measurement of the phase shift between the transmitted and received acoustic vibrations, allowances being made so as to provide a contour indication which is independent of the oscillatory movement of the vehicle. The sine wave picked up by the microphone 4 is amplified in amplifier 5 formed into a square pulse signal in circuit 6, converted into two oppositely sensed needle pulses in differentiating circuit 7 and passed through a rectifier 8 which removes the negative needle pulse leaving a single positive needle pulse which repeats itself every 360 degrees of the phase continuum. The signal from generator 1 besides passing through amplifier 2 to the loudspeaker passes through an adjustable phase network 9, squaring circuit 10, differentiating network 11 and rectifier 12 thus producing a positive needle pulse as the out-going vibration. The outputs of the rectifiers 8 and 12 are connected to a pulse mixer stage 13 the output of which is fed to a bi-stable multivibrator 14 which produces a square pulse signal whose pulse length is directly proportional to the phase shift. The bi-stable multivibrator 14 is connected to a linear integrator 15 which has an associated algebraically-additive output amplifier, not shown separately in Fig. 1. An inductive accelerometer or other oscillation measuring device 16 is fitted with the loudspeaker 3 and microphone 4 at the same point on the vehicle and is connected in one arm of a measuring bridge circuit 17, e.g. a Wheatstone bridge circuit. The bridge is energized by an A.C. supply of suitable frequency, and the variations in the bridge conditions due to vehicle oscillations cause variations in the amplitude of the bridge output signal and by suitable amplifying and rectifying circuits (not shown) a D.C. signal whose polarity and amplitude are representative of the direction and magnitude of the oscillations is produced and supplied to the integrating circuit 15. After integration of the pulse length and double linear integration of the output of the measuring bridge 17, a changing voltage proportional to the distance of the measuring point from the road surface is produced at the output of the algebraically additive amplifier, which voltage is independent of the individual vertical movements of the measuring point caused by vehicle oscillations.

Title: Improved method and apparatus for the centrifugal wringing of cakes of yarns, filaments, cord, ribbon or the like
IPC: D01D10/04
Filed: 1933-09-27
Abstract: 405,584. Centrifugal machines. COMPTOIR DES TEXTILES ARTIFICIELS SOC. ANON., 5, Avenue Percier, Paris. Sept. 27, 1933, No. 26627. Convention date, Oct. 1, 1932. [Class 23.] During the centrifugal drying of cakes of yarn, filaments, cord, ribbon or the like, each cake is rotated about its own axis and about an axis outside itself. The frame 11 supports ball bearings 13 which carry an annular turntable plate 20 to which a ring 21 is bolted. This ring has teeth 23 so that it can be rotated by the motor 30 through speed reducing gearing 34, 32. A number of motors 42 is mounted on the turntable 20 and each motor shaft supports a bucket or drum 51 which thus operates in a ring shaped housing 15 on supports 14 rising from the frame 11. Each bucket 51 has an insert 52 which acts as a wedge and compresses the cake 53 slightly so that it cannot turn. Brake drums 60 are mounted on the spindles of the motors 42, and the brake band 61 is spring- supported on a member 63 mounted adjustably on the supports 14. The band 61 is bent at the end to ensure smooth contact with the brake drums. The motors 42 receive current through the bus-bars 40 which extend round the frame, a sufficient distance to ensure proper wringing of the cake. When the switch 36 is closed, the motor 30 rotates the turntable 20 with the motors 42. These rotate on their own spindles also as long as they receive current from the bus-bars 40, but when they leave the bus-bars their brake drums encounter the band 61 and rotation on their own spindles is stopped while they travel along the brake band. The cakes can be replaced during this part of the working.
