Patent GB-173509-A (GB)
Title: A method and apparatus for reproducing paintings, drawings or prints and the like
IPC: B44F11/02
Filed: 1921-12-22
Abstract: 173,509. Piccioni, G. Dec. 27, 1920, [Convention date]. Copy-holders.-In a method for reproducing paintings, drawings, prints, &c., by graphic means or by embroidery or the like, an original picture or drawing is cut up into narrow strips which are united end to end to form a long strip which serves as a copy and is caused to pass in front of the surface on which the reproduction is to be made. The strip s, Fig. 1, is wound upon spools f, and the paper or other material on which the work is executed is carried by rollers b which are provided with guiding-rings n and are adjustably mounted in frame members a, the upper roller having a hand-wheel o. The copy-strip s is supported by a metal bar i which, for reproduction in embroidery is provided with perforations or teeth for the insertion of the needles. Behind the bar i is a movable guidemember for supporting the work. After a section of the strip has been reproduced on the paper &c. by means such as oil or water colours, pastels, or woven threads, the material is displaced by the width of the strip with the aid of a graduated device p, and a new length of the strip is brought into position. Tn a modification, a working-table r, Fig. 9, is moved in grooves in a frame by means of racks and pinions. The continuous strip may be replaced by strips of wood or cardboard. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also an arrangement in which the picture to be reproduced is strained over a roller, which is rotated at intervals. This subject-matter does not appear in the Specification as accepted.
Patent GB-1516107-A (GB)
Title: Constant pressure pumps
IPC: F04B43/08
Filed: 1975-08-20
Abstract: 1516107 Flexible chamber pumps TELETYPE CORP 20 Aug 1975 [26 Aug 1974] 34585/75 Heading F1A A pump for delivering ink at constant pressure to a printing head nozzle comprises a deformable resilient tube 44 positioned between an anvil 22 and a ram 42, the surfaces of the ram and anvil being shaped such that movement of the ram towards the anvil under the action of a substantially constant force applies a constant force per unit area on the tube. The surfaces of the ram and anvil are concave with a radius of curvature corresponding to the radius of the tube 44 in its undeformed state, Fig. 5 (not shown). As the tube is squeezed by pivoting of the ram 42 about a pivot shaft 16, a pair of arcuate channels 126, 128 centred about the pivot 16 are formed to accommodate the edges of the tube and thus maintain the contact area constant. The ram 42 is mounted on a lever 40 urged in the direction 116 by a spring lever 90 bearing via a roller 88 on its upper surface. A constant force spring 106 wound on a drum 108 biases the lever 90, the spring 106 being connected to the end 96 of the lever 90 by a cable 94 which runs over pulleys 100, 102. At or before the tube 44 is fully compressed, the piston rod 35 of an hydraulic cylinder 34 is moved in the direction opposite to the arrow 52. This causes the lever 40 and a frame 20 mounting the anvil 22 to pivot counter-clockwise about the shaft 16 until a bracket 138 on the lever 90 strikes a fixed stop 140. Continued counter-clockwise movement of the frame 20 and anvil 22 allows the tube to expand and draw thereinto fresh ink through a non-return valve (144) at the end of the tube, Fig. 4 (not shown). Moreover a lifting arm 50 is pivoted about the end 32 of the piston rod 35 by a spring 58 and abuts the frame 20 at a surface 80. The pump is returned to its pumping position by movement of the piston rod 35 in the direction 52. Hence the assembly of the lever 40, the anvil frame 20 and the lifting lever 50 rotate about the shaft 16 and thus lift the spring lever 90. When a screw 110 on the lifting lever 50 engages a stop 112, an extension 54 on the lifting lever rolls leftwardly under the lever 40 until it over-centres to allow the spring lever 90 to act again on the ram lever 40 The cylinder 34 is operated by fluid from a master cylinder (174) operated by a cam driven in steps through a clutch including solenoid operated stops.

Abstract: 1,117,480. Films and fibres of incompatible polymers. W. R. GRACE & GO; 12 Aug., 1965 [14 Aug., 1964], No. 34636/65. Heading B5B. A striated film is obtained by melt extrusion of. a mixture of incompatible thermoplastic polymers (defined as those which do not form homogeneous blends when intimately mixed above the melting point). This may be followed by uniaxial or biaxial stretching of the film by 100 to to 900%; the film may then be mechanically worked or subjected to acoustic energy, possibly in the presence of a non-solvent to break it up into its component fibres. In examples mixtures of polystyrene and polyethylene or polypropylene are extruded and chilled under various specified conditions to give striated films, some of which are uniaxially stretched, cut into pieces and mechanically worked in water in a blender to produce short fibres. The separation into fibres may be incomplete, a network of fibres then being obtained.

Filed: 1968-07-24
Abstract: 1,271,644. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 30 July, 1969 [24 July, 1968], No. 35399/68. Heading G6C. A nuclear fuel sheath has, in cross-section, an internal periphery generally in the shape of a closed three-sided figure having equilateral curved sides such that at least preliminary growth of the fuel housed within the sheath is accommodated by change of shape of the sheath without significant increase of its circumferential dimensions. The sheath may be metal or ceramic. In the embodiment shown in Fig. 2, where circular UO 2  fuel pellets 20 having a bore 22 are housed in a stainless steel sheath 21 in the form of an equilateral curved triangle, there will be unequal temperature distribution as between places 24 where the fuel is in contact with the sheath and places 25 where there is a gap between fuel and sheath. The effect of this inequality can be reduced by having the pellets segmented as indicated by the broken lines 26, or by having the bore 22 modified in shape as indicated by the broken lines 27, or both. The temperature variation around the sheath should preferably be less than 5%, and this could be controlled by modifying the sheath thickness and by means of finning around the sheath. In an alternative embodiment, the fuel is in the form of a non-circular UO 2  rod which has the same shape in cross-section as the area bounded by the internal periphery of the sheath (Fig. 1, not shown).

Title: Method of generating audio-frequencies for superposition on power networks
IPC: H02J13/00
Filed: 1956-11-21
Abstract: 820,129. Electric control systems. LANDIS & GYR A.G. Nov. 21, 1956 [Nov. 22, 1955], No. 35601/56. Class 40 (1). [Also in Group XXXIX] Audio-frequency currents for superposition on power circuits are provided by feeding audiofrequency current produced by a motor-driven generator to a rotary transformer whose rotation is controlled in such a manner as to produce a desired output frequency. As shown, the motor M drives an audio-frequency generator G whose output # 2  is fed to a rotary transformer DT whose rotation is controlled by the device A so as to produce an output frequency F 2 =# 2 Œ #(t). This wobbulated frequency is required for ensuring the response of reed relays at the receivers, which relays are usually sharply tuned, but may have slightly different resonant frequencies due to manufacturing imperfections. The device A may be controlled by the output of a device R which compares the frequency sent to line with that of a programmer P. The control for the rotary transformer DT may be effected as shown in Fig. 2. A constant speed asynchronous motor AM rotates a disc AN in contact with a disc AB coupled to the gear-wheel K. The programmer P operates on the device R which longitudinally advances the spindle S1 so causing the disc AB to rotate at a variable speed. The gear-wheels K, L and hence the rotary transformer DT all rotate in sympathy. The programmer P may instead be a fixed frequency standard, if the output frequency is desired to be constant.
