Title: Stencil Laminate Material.
IPC: B44F1/04
Filed: 1966-10-18
Abstract: 1,165,573. Laminates for use as stencils. PITNEY-BOWES Inc. 18 Oct., 1966 [23 Oct., 1965], No. 46603/66, Heading B5N. [Also in Division G2] A stencil laminate comprises a layer of a pressure-spreadable composition including a wax-like material and a pigment capable of reflecting radiation in the range of 7,000 to 30,000 angstrom units, the layer being between sheets of a material which are transparent to radiation, and capable of transmitting pressure to the pressure spreadable composition. The wax-like materials may be natural or synthetic waxes, e.g. spermaceti wax, carnauba wax, beeswax, castor oil wax, stearic acid or glyceryl monostearate, and the pigments may be titanium dioxide or antimony oxide. Suitable sheet materials are polyethylene terephthalate, polyethylene, polypropylene, polyvinylidene chloride, cellulose acetate, acrylics, polystyrene, cellulose acetate-butyrate, cellulose nitrate, and polyvinyl butyral. The composition may also include an oily material, a surface active agent and a thixotropic agent. The laminate may be formed by coating one side of a web of the sheet material and passing it together with a second web of the same or a different sheet material, itself coated or uncoated with the composition, between two rollers accompanied by heating. Areas of the stencil impressed, e.g. by typing thereon, become more transmissive of infra-red radiation than the remaining areas. The stencil may be impressed before lamination as by typing upon a sheet material coated with the composition, laying on a throwaway receptor sheet, and subsequently laminating to a second sheet material, or it may be impressed after the laminate is formed. In the former case the second sheet material may be coated with a pressure-sensitive adhesive or it may be mechanically attached to the composition coated sheet at its edges.

Abstract: 1351438 Valves; seals DANFOSS AS 12 Oct 1972 [12 Oct 1971] 47110/72 Headings F2V and F2B In a seal for a valve stem 16, an element 27 expands when contacted by fluid leaking past a seal 22. Further leakage and movement of the stem are thus prevented. The element 27 may be of leather or be formed by discs or a coil of hydrated cellulose, such as vulcanized fibre. A felt ring 23 serving as a filter, and metal rings 25, 26, hold the seal 22 in position in a bore 24 of a bush 18. The bush may form part of a manually or thermostatically actuated valve for a heating system, the thermostatically actuated valve having a vapour element opposed by a spring with an adjustable abutment to determine the temperature setting.

Abstract: 1,021,827. Cutting spectacle lenses. SOC. DES LUNETIERS, COTTET, POICHET TAGNON & CIE. Dec. 13,1962 [Dec. 15, 1961; Sept. 24,1962], No. 47138/62. Heading G2J. In order to determine the outline which must be cut out of a lens for mounting in a spectacle frame so that the optical centre of the lens is aligned with the pupil of the wearer's eye at the geometrical centre of the frame, lens and frame are superposed, placed in position on the wearer, and then photographed,as in Figs .1 or 2,(not shown) by some means such as a Polaroid (Trade Mark) camera which produces an immediate copy. This is then inspected, using a projector if necessary. Fig. 5 shows an example, in which the uncut lens A is superposed on the mount F whose geometric centre is at C. By measuring the distances a, b between the wearer's pupil B and the point C, the optician can cut the lens correctly.

Abstract: 949,760. Generators operating by electro - magnetic interaction with fluids. LITTON INDUSTRIES Inc. Dec. 18, 1962 [Dec. 21, 1961], No. 47652/62. Heading H2A. A magnetohydrodynamic generator has the ionized gas oscillated in both directions through a magnetic field so that A.C. is generated directly at the electrodes. Two funnel-shaped containers 25, 27 are connected together by a throat member 29 which functions as the duct of a M.H.D. generator having electrodes 23 and a magnetic field produced by magnet 21. The oscillations of the gas have a frequency corresponding to an acoustic resonant frequency of the container and are sustained by supplying a pulse of thermal energy to the gas when the latter is at high pressure and simultaneously removing thermal energy from the low pressure gas. As shown, if the pressure in heat exchanger 17, whose coils 35 are heated from a nuclear reactor, is arranged to be intermediate between pressures Pa and Pb developed in the gas at points a and b gas will be extracted through port 37 and heated gas will pass into chamber 25 through port 39. Simultaneously at the low pressure end 31 gas will pass out through port 72 and cooled gas be added through port 70. In a modification, the generator is dumb-bell shaped and fuel is housed at each end of the chamber when the gas at the respective end is at high pressure; the waste heat is extracted in the throat portion, Fig. 3 (not shown). By providing a magnetic field which reverses in phase with the direction of flow of the gas in the duct a unidirectional output voltage may be obtained.

Abstract: 1,094,978. Endless conveyers. BOTALAM. Nov. 12, 1965 [Nov. 19, 1964; March 12, 1965], No. 48179/65. Heading B8A. Rods 3 conveyed in continuous succession on endless conveyers 1 have their ends picked up on a worm 9, counted by a counter 10, and transferred to the teeth of a feed wheel 4. The latter is the first at the end of a series of wheels 4 on a shaft 5. Thus each rod after being engaged on the first wheel 4 is progressively engaged by the teeth of succeeding wheels 4 and then thrown on to a discharge ramp 8 (Fig. 2, not shown). There may be an auxiliary endless conveyer (17) (Fig. 3, not shown). Instead of the worm 9, a toothed rotary member (34) (Fig. 4, not shown) may transfer the ends of the rods 3 from the conveyers 1 to an auxiliary endless member (29). A counter (37) may raise a lever (42) when a batch has been delivered. The forward surface (43) of the lever (42) deflects counted rods still on the rotary member (34) so that they fall on to the endless member (29). A surface (42) then acts as a barrier to prevent further movement of uncounted rods.

Abstract: 1328161 Measuring dimension COMMISSARIAT A L'ENERGIE ATOMIQUE 19 Oct 1970 [6 Nov 1969] 49441/70 Heading G4H In apparatus for measuring the dimension of cylindrical objects 36 (Figs. 1 and 6) e.g. nuclear fuel pellets, the distance between the external faces of two reference stops 38, 38a is first found and entered into a counter 32 (Fig. 1) when the light from movable sources 22, 22a is cut off from detectors 28, 28a movable with sources by the stops 38, 38a. The light sources and detectors are then stepped towards each other, the counter being decremented at each step of each light source until the edges of the object 36 are detected when the count is displayed. As described objects 36 to be measured are carried on a stationary supporting stage 34 and the light assemblies are carried on motor driven stirrup shaped members 20, 20a. The light which is from either incandescent lamps or preferably from gallium arsenide diodes is directed via light guides to photodetectors 28, 28a which are preferably silicon photodiodes. Initially a gage of known dimension is placed on the stage 34 and a valve corresponding to the approximate distance between the stops 38, 38a is entered in a store 33. The light assemblies are moved outwards until auxiliary stops 40, 40a are detected and the direction of movement is reversed. When stops 38, 38a are detected the contents of the store 33 are entered into counter 32 and subsequent movement of the assemblies by stepping motors 12, 12a, energized sequentially, results in pulses being subtracted from the count until the reference gage is detected. Any errors in the displayed count from the known size of the reference gage are used to adjust the value in the store 33. Object 36 may then be measured with the calibrated value in the store being read into the counter when steps 38, 38a are detected, calibration being carried out before each measurement or only periodically. When calibration is effected only periodically the light sources are only moved between the internal faces of stops 38, 38a in the external faces of the objects 36 being measured, the counter accumulating pulses subtractively as the light assemblies are moved together and additively as they are moved apart. The stops 38, 40 and 38a, 40a are preferably linked by a bridge (37, Fig. 2, not shown) of a material having the same coefficient of expansion as the material of the object being measured to compensate for variations in temperature.
