Abstract: 543,263. Conditioning soles. BRITISH UNITED SHOE MACHINERY CO.. Ltd., and ROBSON, W. S. Aug. 16, 1940, No. 13079. [Class 17 (i)] An apparatus for treating shoe soles by heat and moisture comprises a casing which is closed after the introduction of the work, a water tank with the receptacle with means for heating the same, a rack for supporting the workpieces within the casing a thermostat for controlling the temperature and means for directing the flow of hot moist air in a path within the casing to treat the soles. A casing 11 normally closed at the front by counterweighted doors 31, 33 is spaced from an asbestos lined outer casing B, and contains a water tank 71 formed to act as a baffle for air heated by electric heaters 115, 117 controlled by a thermostat in the upper part of the casing. The tank is supplied with water on the "bird fountain" principle from a tank 89. Superposed pairs of combs 65, 67 support blank soles within the casing. Sheets of muslin 105, 107 depend into the water tank and become saturated by capillary action. Air heated by the heaters rises between the tank and casing and passes through the muslin becoming saturated with water vapour. It descends through the assemblies of soles and thus circulates in the casing. Specifications 1070/08, [Class 31], 215,443, [Class 17 (i)], 408,953 and 467,591, [Group VIII], are referred to.

Title: Dynamically compensating weighing scales
IPC: G01G7/02
Filed: 1963-04-03
Abstract: 990, 130. Measuring weight electrically; photo-electric systems. S. B. BLODGETT. April 3, 1963 [June 15, 1962], No. 13138/63. Headings G1A, G1N and G1W. In a weighing machine wherein the weight of a container being filled with fluent material deflects a spring loaded rod, the latter is coupled through a dashpot to a further deflectable rod, the two deflections being measured electrically and subtracted to eliminate common external vibration components and to allow for impact effects when weighing discrete objects, or added to allow for the quantity of material in the pipe line to the container. As shown (Fig. 1), the weight of a container 8 produces proportional deflection of a spring- loaded rod 6, which is sensed by a differential transformer T1. A similar spring-loaded rod 11 whose displacement is measured by differential transformer T2 is coupled to rod 6 by a dashpot 12. Thus, with the transformers T1, T2 connected in opposition, signals produced by vibration of the common base 3 are cancelled. Furthermore, the dashpot 12, which is a differentiating device, produces an additional displacement of rod 11 as the result of impact on rod 6 when discrete solid elements are dropped into the container 8, thereby also cancelling the impact signal. The time constant of the dashpot is such that it ignores normal feed rates. Alternatively the transformer T1, T2 are connected in series winding, when the additional rate signal represents the quantity of material in the pipe line which will be added to container 8 after a cut-off value has been reached. In a practical embodiment (Fig. 2), an additional dashpot 28 is added to the weighing rod 6. In another embodiment (Fig. 10) the deflections of the weighing rod 50 and the compensating rod 64 are measured and automatically subtracted by a photoelectric system comprising a fixed lamp 70 and lens 71, a shutter 73 mounted on rod 50, and a focusing lens 72 mounted on rod 64. The amount of light reaching a photo-cell 73 is determined by the difference in the displacements of rods 50, 64. In an alternative arrangement (Fig. 11, not shown), the displacements are added photo-electrically. The dashpot 12 may be replaced by a magnetic eddy current coupling device comprising an aluminium vane attached to one rod, located between the poles of a magnet attached to the other rod.

Title: Method of forming protective layers on iron and steel articles
IPC: C23C10/10
Filed: 1934-05-03
Abstract: Chromium is introduced into the surface of articles of iron or steel by heating the articles with solid chromium chloride in a reaction chamber at a temperature of 850-950 DEG C.  The chromium chloride reacts with the iron and the iron chloride vapours formed are led away through an outlet in the reaction chamber. Alternatively, gaseous chromium chloride, which may be made by passing chlorine or hydrogen chloride over heated chromium or ferrochromium, is passed into the reaction chamber where it reacts with the iron or steel articles which are heated to 850-950 DEG C.  If desired, the synthesis of the chromium chloride may be effected in the reaction chamber itself, by passing chlorine or hydrogen chloride into the chamber which contains chromium or ferrochromium and also the iron or steel articles to be treated.  In all cases the resulting vapours are led away from the reaction zone.  The exterior layer of the treated articles is stated to contain about 40 per cent of chromium.  The treatment of threaded pipes is referred to.

Title: Photographic camera or film cassette for use with perforated film
IPC: G03B17/30
Filed: 1969-03-14
Abstract: 1,263,313. Film transport mechanism. AGFA-GEVAERT AG. March 14, 1969 [March 19, 1968], No. 13477/69. Heading G2A. The actuation of the shutter release of a camera also releases a film transport lock, thus allowing the film to be wound on. Fig.1 shows the mechanism ready for an exposure, A slide 11, mounted for vertical movement, has a spring arm 17, of which the free end is anchored in a fixed part 18 of the camera housing, and which urges the slide downwards. When a further arm 12 of the slide is aligned with a perforation in the film 1 as it winds across from spool 4 to spool 5, it enters the perforation, and so locks the film against further movement. Another arm 13 of the slide carries a locking tooth 14 which, in the position shown, engages in a toothed rim 3c on the transport wheel 3, so preventing it from rotating. At the upper end of the slide is a stop pin 19. A second slide 20 is attached to the shutter release 21, and can move backwards and forwards in the directions A-B. On moving in direction A, the cam edge of slide 20 engages pin 19, and so raises slide 11 (direction C). This frees arm 12 from the perforation, and tooth 14 from wheel 3, thus allowing wheel 3 to be rotated in the direction E. A further flexible arm 15 of the slide 11 has a point 16 which engages frictionally against the toothed section 3a, and holds slide 11 up long enough for the film to begin moving. The slide is then returned again by the spring action of arm 17 until arm 12 rests on the surface of the film, and engages in the next perforation, so returning to the transport locking position of Fig. 1. For the next exposure, shutter release 21 is moved in direction B, and the previous sequence of operations repeated. The shutter comprises a single disc 23 rotating on a pin 35 between two extreme positions defined by one or other of edges 38, 39 abutting against a fixed stop 40. The exposure is effected by a slot 36 in the disc passing an exposure aperture 37. The disc is driven by an overcentre spring 41, attached to the disc at one end 42, and at the other end 43 to an arm 21b of the shutter release 21.

Title: Improvements in or relating to the examination of materials by means of x-ray
IPC: G01N23/18
Filed: 1953-05-14
Abstract: 724,350. X-ray apparatus. AKT.-GES. BROWN, BOVERI & CIE. May 14, 1953 [May 14, 1952], No. 13539/53. Class 98 (1). [Also in Group XL (a)] In a method of producing a radiograph, especially for investigating materials by means of X-rays from a dualbeam betatron, the object to be examined is ',irradiated by two X-ray beams whose axes intersect, whereby when the object is located at a first distance from the beam source a section is irradiated for the purpose of detecting faults, and when the object is located at a second distance approximately twice as great as the first distance a section approximately half as great is irradiated for the purpose of locating the faults. Apparatus for performing the method is characterized in that in the toroidal acceleration tube of the betatron a pair of targets is provided which subtend an angle of at least 160 degrees at the axis of the betatron, and that means are provided which guide the electrons, which are accelerated alternately in opposite directions, alternately to the targets. As shown, a betatron has targets 1, 2 which each produce an X-ray beam (see Group XL (a) ). The beams are tangential to the electron orbit, so that, since the targets subtend an angle # at the betatron axis 6 which is at least 160 degrees, the axes 3, 4 of the X-ray beams intersect at an angle α not greater than 20 degrees. The aperture angles # of the beams are limited as by diaphragms to 15 degrees or less. The object 7 is first placed where the beams begin to intersect, and a radiograph is made on a film 8 placed directly behind the object 7. From this radiograph the presence of any flaw in the material of object 7 can be detected. To locate the flaw, the object is placed at twice the distance from the betatron, in the region where the axes 3, 4 intersect, and a radiograph is made on a film 9 directly behind the object. A double image of the flaw is produced, from which its position can be deduced. Alternatively, the film may be moved to a position 10, in which the images are separated. Such images may be used as a stereoscopic pair. If preferred, radiographs may be made successively on two films placed at 9, suppressing each beam in turn, and the resulting images may be used as a stereoscopic pair. Specifications 656,627 and 682,504, [both in Group XL (a)], are referred to.

Title: Process for the treatment of formed bodies from high molecular weight thermoplastic polycarbonates
IPC: C08J7/12
Filed: 1961-04-14
Abstract: Formed articles of high-molecular weight thermoplastic polycarbonates are treated, optionally at an elevated temperature, with aqueous or alcoholic solutions of alkali or alkaline-earth metal hydroxides. The articles, which may be foils, fibres, bristles or domestic articles, are thereby given a uniform roughened, matt surface which is suitable for marking with dyes, inks, pencils and the like.  The surfaces so treated also have improved adhesive properties for coatings of various materials.  The process can be applied to articles which have been dyed, and, by the use of suitable masking techniques, pre-selected portions of the surface may be treated.  The process does not impair the chemical, mechanical or electrical properties of the formed articles.  In the examples, articles made from a melt of bis-(p-hydroxyphenyl)-dimethyl-methane polycarbonate are dipped in a 50% aqueous solution of sodium hydroxide at 80 DEG -130 DEG  for 1-8 minutes.  The articles so treated are washed free from alkali with water and acetic acid.
