Title: Push-in easy-opening closures
IPC: B21D51/44
Filed: 1971-09-15
Abstract: 1361784 Push-in closures for sheet-metal containers BROKEN HILL PTY CO Ltd 15 Sept 1971 [16 Sept 1970] 43031/71 Headings B8C and B8D [Also in Division B3] An easy-opening closure in a container made from sheet metal comprises an opening 16 formed by severing a part, or whole, portion of the sheet metal and a closure member 12 formed from, or comprising, the severed portion and which is larger than the opening 16, the closure member 12 having a part of a free edge portion 19 thereof in contact with, or in close proximity to, said free edge 17 defining the opening. If required, the edge of the opening is sealed interiorly by a sealant S. As shown, a can end 10 has two cut-out closure members 12 each of which remains connected thereto by a narrow hinge portion 14 and is resiliently biased upwardly towards the opening, the area of the closure member 12 being larger than that of the opening. The sealant S is made for instance of any suitable polymer such as P.V.C.; it may, however, be provided by the lacquer commonly applied to the interior surfaces of the container. A push-in closure is formed by first forming an upward bulge 20 and severing it at a shoulder 22 to define the opening 16 and the hinge portion 14, partially flattening the truncated portion around the opening 16 to reduce the size of the latter, turning the free edge of the opening downwardly, partially flattening the closure member 12 to increase its size, and finally turning the free edge of the member 12 upwardly. Sealant S is then applied. The desired overlap "x" may be obtained in other ways, for example the bulge may be of annular shape or, the bulge, or part of it, may be deformed downwardly. Alternatively, the bulge may have a flat surface, Figs. 13-17 (not shown), in which case the overlap is provided solely by the partial flattening of the truncated bulge around the opening 16. If the member 12 is wholly severed from the container a hinge portion, such as 14, may be provided by a strong adhesive material.

Title: Improvement in process and apparatus for extruding thermoplastic tubing and tubular films
Inventor: LYON JOHN BENNETT
IPC: B29C48/90
Filed: 1969-08-29
Abstract: 1,270,865. Tubular films; extrusion. E.I. DU PONT DE NEMOURS & CO. 29 Aug., 1969 [30 Aug., 1968], No. 43079/69. Headings B5A and B5B. A tubular film casting and orientation process comprises the steps of (a) extruding a molten thermoplastic polymer through an annular die, and (b) melt-drawing the tubular film so formed over an internally cooled mandrel having a portion of reduced outer diameter immediately downstream of the die, introducing helium gas radially of the mandrel and adjacent in a zone between the die and the plane of initial quenching in a direction toward the interior surface of the film and circulating the gas in the zone, the temperature of the helium being substantially below the film temperature in the zone. The helium may be removed radially at a location closer to the annular die than the location of helium introduction, thus providing a helium flow counter-current to the movement of the tubular film. The polymer may be polyethylene or polypropylene. The pressure of the helium in the zone may be sufficient to resist neck-in of the film. The plane of initial quenching is the plane perpendicular to the axis of the mandrel defined by the circumferential touch-down point at which the tubular film first contacts the mandrel as it is drawn thereover along its length. As shown, a tubular film 10 is drawn from the swollen molten polymer ring 11 which is extruded from the annular die 12. The internal quench mandrel 13 is provided with internal cooling means (not shown) and has an undercut portion 14 extending from the leading edge 15 of the mandrel to the ring 16 round the mandrel at which the tubular film first contacts the mandrel. The mandrel is supported on the face of the die 12 by the post 20. Helium at a temperature substantially below that of the portion of the film adjacent the undercut portion 14 of the mandrel enters the zone between the plane of initial quenching 16 and the die 12 through inlet duct 21 and radial helium entrance ducts 22. Volatile components present in the polymer diffuse readily through the helium in the zone and condense on the undercut portion 14 of the mandrel. Absorbent packing 23 may be provided to absorb the condensate and exit ducts 24 and 25 are provided in the support post 20 to permit the helium to flow through packing 23 and out through the ducts 26. The packing 23 is supported on baffle plate 27 and an insulation disc 28 may be provided to cover the face of the die 12. The production of polyolefin films is exemplified.

Title: Holography
Inventor: GREENAWAY DAVID LESLIE
IPC: G06V10/88
Filed: 1968-09-10
Abstract: 1282716 Holography RCA CORPORATION 10 Sept 1969 [20 June 1968 (2) 10 Sept 1968] 43055/68 43082/68 43083/68 Divided out of 1280996 Heading H4D [Also in Division G2] Annular holograms are formed by locating an object on the optic axis of a coherent refence beam so that the reference beam only illuminates an annular area of a recording medium and interferes thereon with a coherent light beam from the object. A single laser beam 200 may be used, that part passing around an object 218 forming an annular reference beam. The central portion of the beam passes through a diffuser 216 and object transparency 218 and is diffracted to holographically interfere with the reference beam portion on an annular hologram plate 214. A circular diffraction grating may be used in place of the diffuser. Alternatively an annular prism 600 may be located at the periphery of a plane coherent light beam 604 to form two beam portions 606 which focus on an object and diverge therefrom to illuminate an annular portion 614 of a hologram plate 612. The object 610 is again illuminated by the central portion 608 of the beam 604. Examples are also given where an annular portion of a parabolic mirror is illustrated by a reference beam, the object being illuminated by a coherent beam passing through an aperture in the centre of the mirror. The hologram plate is then located intermediate the mirror and its focus. The initial beam can be split into two by any conventional mirror or prism arrangement. Real images are reconstituted by re-illuminating the annular hologram with an annular reference beam conjugate with the original reference beam. At any one time only a segment of the annular hologram plate need be utilized for one hologram. Consequently a plurality of adjacent holograms may be sequentially formed on one plate. Two examples are given where the annular hologram is formed without object information, this being included in the reconstructing beam, but one of the forming beams is modified by a multiple lens area. These are disclosed in more detail in Specification 1280996. Acoustic energy may be used in place of coherent light.

Title: A Device for Detecting Insulation Faults in Electrical Apparatus.
IPC: H02H3/16
Filed: 1966-09-27
Abstract: 1,164,296. Protective arrangements. ATELIERS DE CONSTRUCTIONS DE VAUXANDIGNY and R. A. GUASCO. 27 Sept., 1966 [4 May, 1966], No. 43126/66. Heading H2K. An earth leakage protective arrangement includes a light emitting element, e.g. a gas discharge tube T 1 , means for applying to the element a voltage resulting from an insulation fault, and a photo-conductive element S 1  optically coupled to the tube T 1  and effective to cause operation of a control device, e.g. the release of a circuit-breaker K. In the arrangement shown, the tube T 1  is connected across the supply conductors to a load Z in series with a resistor R 1  and the secondary winding E 3  of a core-balance transformer N. The resistor R 1  and a potentiometer P 1  form a voltage divider across the supply, the tube T 1  being normally energized by the voltage across the potentiometer P 1  and being lit so that the conductive element S 1  has a low resistance. This element S 1  shunts a further discharge tube T 2  which is not lit so that a further photoconductive element S 2  has a high resistance and prevents a trip coil B being sufficiently energized to trip the circuit-breaker K. In the event of earth leakage the voltage induced in the winding E 3  opposes that across the potentiometer P 1  and the tube T 1  is extinguished. The element S 1  now has a high resistance so that the tube T 2  strikes and illuminates the element S 2 . The resistance of the latter element S 2  falls, so that the coil B is sufficiently energized to trip the circuit-breaker K. Fig. 1 (not shown), illustrates an arrangement in which a first discharge tube is energized from an autotransformer in a connection to earth from the frame of a machine. The associated photoconductive element is connected in series with a further discharge tube associated with a further photo-conductive element in series with the trip coil. A further arrangement, Fig. 2 (not shown), has a single discharge tube connected between the frame of a machine and a neutral conductor.

Abstract: 946,507. Battery cages. JOHN SHEPHERD & SONS Ltd., and W. SHEPHERD. Nov. 26, 1962 [Dec. 2, 1961], No. 43170/61. Heading A1M. In a structure for housing livestock, particularly poultry, rows of cages 11-13 are supported on a framework 10 in stepped formation so that droppings from the cages fall on to an area within the confines of the framework at or near ground level, the cages of one row partially overlapping those of the next lower row and deflector screens being provided to prevent droppings falling into a lower cage. The framework comprises uprights 17 at each end of each row, longitudinal members 18, 19 defining upper and lower edges of the cages, and struts 22, 23, the members 18, 19 being secured together by tie rods 20 and the members 19 being shaped to provide deflector screens 19a. The droppings receiving area may be formed by a trench sunk below ground level or panels may be attached to the lower side parts of the framework to form a trough. Droppings may be removed by means of a sheet or band resting on a chain or meshwork base withdrawable from either end of the battery, or by a plough or scraper connected to a cable driven by hand or by an electric motor. The structure may be raised from the ground by a pulley block and tackle, two such structures being suspended from a common pulley so that as one structure is raised the other is lowered. In a modification the rows of cages may be stepped down one side only of the structure. Specifications 801,139 and 871,506 are referred to.

Title: Improvements in or relating to processes for recording and reproducing data on recording carriers
IPC: G11B7/24
Filed: 1965-10-14
Abstract: 1,093,436. Electron beam irradiation apparatus. A. E. DE RUDNAY. Oct. 14, 1965 [Oct. 15, 1964], No. 43547/65. Heading H1D. [Also in Division G5] A record consists of a solid body or a thin layer of an inorganic material which is selectively reacted with a suitable gas to produce a surface able to modulate an impinging optical or particle reading beam. In a first example, a metal layer of the platinum group, preferably palladium is bombarded by electrons, positive ions or irradiated by infra-red radiation in an atmosphere of hydrogen the beam selectively heating the layer locally to a temperature at which the hydrogen is adsorbed. The recording beam, or some other beam, used at a lower intensity is used to read the record optically. Erasure is achieved by so adjusting the beam intensity that the hydrogen is expelled and positively removed by gettering means. In a second example, the layer is presaturated with hydrogen and recording is made by selective de-hydrogenation with the recording beam. In other examples, superoxides such as TiO 2 , MnO 2  are reduced to lower oxides by heating, or silver or copper layers may be selectively oxidized by bombardment with oxygen ions.

Title: Electrolysis cell system including recirculating product gas stream for cooling the cell
IPC: H01M8/04
Filed: 1975-10-23
Abstract: 1492463 System for electrolytic hydrogenoxygen production UNITED TECHNOLOGIES CORP 23 Oct 1975 [20 Nov 1974] 43599/75 Heading C7B The system comprises an electrolysis cell 12 having an aqueous electrolyte matrix 18 between a pair of gas diffusion electrodes 14, 16. A gas space 24, 26 is provided behind each electrode and the cell has a thermal exchange portion 22. A portion of one product gas (H 2  as shown) passes from its gas space, through the portion 22 and returns to the gas space. Coolant water e.g. in droplet form is added to this gas at 46 before entering portion 22, whereby cooling of the cell is effected by water evaporation and a temperature gradient established across the cell. Such gradient is reinforced by recycling the gas in space 24 countercurrent to the flow through 22. The outlet temperature of the gas from 22 is monitored at 48 and maintained constant by automatic control of water supply valve 50. Heat in the gas is removed in a condenser 52, the gas outlet temperature being maintained in a range to give a desired water partial vapour pressure in the cell by controlling the degree of condensation by means of a variable by-pass line 66 in the condenser coolant circuit. Condensed water is separated at 60 and recycled via 62 to the sprayer 46. Remaining water vapour in the gas passes into the cell and is absorbed to replace that electrolyzed. Valves 37 control the gas pressures in the cell. An optional electrolyte storage matrix 20 may be included. A basic (e.g. KOH) or acid electrolyte may be used.

Filed: 1974-10-08
Abstract: 1482957 Space dyeing yarns INTERDYE TECHNOLOGY CORP 8 Oct 1974 [2 Jan 1974] 43606/74 Heading D1L Yarns are space dyed by firstly completely immersing skeins of the yarn in a first dye bath and then partially immersing the skeins in a second and optionally a third dye bath, to varying depths. The skeins are supported on pairs 42 of parallel bars 44, 45 which, together with rear edge brace 49 and removable front edge brace 50, form racks 40 suspended at 56 by adjustable length chains 66 from harness 60, the harness being supported by cables 77, 78 and 79 from hoist 70. The bars 44, 45 are interconnected by arcuate saddles 46 which rest on dye tubes (34) [Fig. 6 (not shown)]. The skeins. which encircle the bars 44, 45 and tubes (34), are retained thereon by front edge brace 50 which is removable by withdrawal of bar 54 extending apertures in tabs 47 (which extend through slots in the brace) attached to saddles 46 [see Fig. 6]. The dye tubes (34) extend from a central conduit (32) which is supplied with re-circulated dye liquor via hollow legs (30) and cross-member (29) which has openings (31) disposed above openings (26) in the false bottom (22) of he vat 20 [Fig. 12 (not shown)], dye liquor being re-circulated by pump (25). In operation the 4 racks 40 containing the skeins are lowered together with the dye tube assembly into the vat using hooks (33) [see Fig. 12]. The racks are then attached to the harness 60 and the vat filled with hot water to bulk and heat set the yarn. Following addition of the first dye to the aqueous bath and exhaustion thereof, the skeins are removed. A second dye is then added and the skeins lowered to partially immerse the skeins therein. Uneven dyeing may be obtained as illustrated in Fig 3a (not shown) by tilting the racks by varying the lengths of the chains 66. Power jacks may also be used [Figs. 13 and 14 (not shown)]. A third dye may be used to give the effect illustrated in Figs. 2B and 3B (not shown).

Filed: 1971-09-20
Abstract: 1313488 Error detection and correction INTERNATIONAL BUSINESS MACHINES CORP 20 Sept 1971 [31 Dec 1970] 43651/71 Heading G4A In a data processing apparatus data words are stored in a single-error-correction/double-error detection Hamming coded form from which, during a read cycle, is generated an error detection and correction syndrome but pattern from which can be determined where the error if any lies. Single chuck bit errors and double errors are dealt with as described in Specification 1,293,488 but in the present Specification a single data bit correction circuit is provided which detects and corrects only the erroneous byte of the data word instead of operating on the whole word. In a first embodiment (Figs. 2 and 6, not shown) the syndrome bit pattern is stored in a register S; from this pattern is generated a signal indicating which byte is in error, this signal being gated into a register X. The signal in the register will be all zeros except for a single 1 indicating the erroneous byte. The register is then rotated step-by-step. For each step of the X register a set of gates (Fig. 2A, not shown) present a new byte of the data word to the correction circuit and also for each step of the X register the S register is rotated one step. At each step of the latter a matrix (258) generates a new correction pattern and when the 1 reaches the end of register X the correction pattern is also gated to the correction circuit (Fig. 2D, not shown) to correct the erroneous byte. In this embodiment the stepping of the two registers X, S and the gates continues until all the bytes have been presented in turn to the correction circuit. In a modification (Fig. 3, not shown) the stepping is stopped as sc on as the erroneous byte has been corrected In a third embodiment (Fig. 4, not shown) the S register is not stepped but all the correction patterns are generated simultaneously in a matrix (Figs. 4G, 4H); the X register is omit ted, its signal being used directly to gate in the erroneous byte and the respective correction pattern. In a fourth embodiment (Fig. 5, not shown) all possible correction patterns are stored in a microprogram and the correction procedure is carried out by the ALU of the data processing apparatus.

Title: Dual bidirectional valves and filter assemblies and hydrostat systems containing the same
IPC: F15B21/041
Filed: 1975-10-29
Abstract: Arranged in tandem in the housing (1, 2) of the double coaxial valve (V1, V2) acting as a "hydraulic rectifier" are two valves (A, B), each of which has an outer valve element (3, 4) and an inner valve element (5, 6). The valve elements are of tubular design and inserted coaxially one inside the other. In each valve, a single compression spring (19, 20) presses the outer element (3, 4) against an outer valve seat (7, 8) and the inner element against an inner valve seat (25, 26). To ensure that the valve elements (3, 4, 5, 6) open in the desired direction of flow, pressurisation surfaces (15, 16, 59, 28) are provided at their ends. In the case of flow in direction A', the outer element (3) of the first valve (A) and the inner element (6) of the second valve (B) open, while the other elements (4, 5) are pressed against their seats (8 and 25). In the case of flow (B') in the opposite direction, the elements (4, 5) are opened and the elements (3, 6) are closed. The valve is used in a hydrostatic arrangement in order to ensure unidirectional flow through the oil filter (60-62) even in the case of an alternating direction of flow. <IMAGE>
