Title: Liquefied gas container
IPC: F17C3/08
Filed: 1962-09-17
Abstract: 951,875. Storing liquefied gases. SUPERIOR AIR PRODUCTS CO. Sept.17, 1962 [Oct. 9, 1961], No. 35293/63. Heading F4P. A container for the storage of liquefied gas comprises a storage chamber 10 having a vacuum jacket 13 thereabout, a first tube 27 communicating at one end thereof with the chamber 10 for the introduction and removal of the liquefied gas, a second tube 29 arranged in spaced relation to the tube 27 through a major portion of the length of the tube 27 which with the tube 29 defines an elongated space 30 communicating at one end thereof with the chamber 10, and a pressure relief valve 32 communicating with the space 30 and arranged to open to the atmosphere, the space 30 being closed except at the said one end thereof and at the pressure relief valve. The chamber 10 is defined by a wall 11 which is surrounded by a spaced wall 12, the space between the walls 11 and 12 forming the jacket 13. The jacket 13 may be insulated by other means, e.g. multiple reflector shields. Another wall 14 surrounds the wall 12, the space 15 between the walls 12 and 14 being filled by another liquefied gas which acts as a heat shield. If the stored gas is helium, hydrogen or neon, the other gas may be nitrogen. An outer wall 16 surrounds the wall 14, the space 17 between the walls 14 and 16 being evacuated; the space 17 may be insulated by other means also. The walls 11, 12, 14 and 16 and the tubes 27 and 29 are preferably made of stainless steel or Monel metal. A tube 34 is spaced from and surrounds the tube 29 and is preferably made of copper or a copper alloy having high heat conductivity, the space 35 between the tubes 29 and 34 being sealed by a ferrule 36 made of the same material. A tube 37 is spaced from and surrounds the tube 34 and tube 39 is spaced from and surrounds the tube 37, the tubes 37 and 39 being made of stainless steel or Monel metal; alternatively the tube 39 may be made of copper. A ferrule 42 seals off the space 40 between the tubes 37 and 39 and extends almost to the tube 29 to which it is joined by a bellows member 45. A filling tube 46 extends through the space 38 into the gas space 15, the gas in the latter being vented to atmosphere through a tube 47. A serrated ferrule 48 made of copper or copper alloy extends between the tubes 27 and 29 in the area of the ferrule 36. The above construction ensures that heat travelling down tubes 27 and 29 will be diverted away from the gas in chamber 10 to that in space 15. The serrated ferrule 48 may be replaced by a ferrule having axial holes passing therethrough.

Title: Scanning electron microscope system for investigation of specimen structures
IPC: H01J37/28
Filed: 1976-08-25
Abstract: 1532862 Automatic control CARL-ZEISS JENA VEB 25 Aug 1976 [24 Sept 1975] 35384/76 Heading G3N In a scanning electron microscope system for measuring the separation of two points on a specimen 9, image signals 13 from detectors 10, 11, 12 are fed via circuitry 16 to a cathode ray tube, e.g. 20, associated with a device 23 which projects a calibrated grid on to the c.r.t. screen; a distance which is measured using the grid being the sum of a relatively small displacement of the electron beam caused and measured by a deflection system 21x, 21y, and a relatively large displacement caused by movement of the specimen and measured by a further measuring system. The two displacements are automatically combined and fed to a display unit 22. The arrangement permits the measurement of distances up to a decimetre with an accuracy of a tenth of a micrometre. The positioning of the specimen may be preselected and actuated via data input member 29 either manually or by numerical control, e.g. punched tape. The specimen is moved by stepping motors 27 under the control of a computer 28, and the x and y displacements of the specimen are measured by a laser system 30 incorporating measuring prisms 31 and reference prisms 32.
Patent GB-635991-A (GB)
Title: Improvements in or relating to injection moulding apparatus
IPC: B29C45/72
Filed: 1946-11-30
Abstract: 635,991. Injection-moulding machines. VLTAVSKY, V. Nov. 30, 1946, No. 35535. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 30, 1946] [Class 87 (ii)] The melting chamber 12 is filled with material by means of a plunger 10 that forces the material from a pre-melting smaller chamber 4 past a non- return valve 13, and then the melting chamber and mould 18 are raised, the chamber telescoping over an extension 11 of the pre-melting chamber, this extension thus serving as a plunger and forcing material from the melting chamber through a valve 17 into the mould. The melting chamber is raised by hydraulic pistons 15 operated by a highpressure accumulator. During filling of the melting chamber the pressure below the pistons 15 is maintained low or at atmospheric pressure ; when the pressure is maintained low, it compensates for the weight of the chamber 12, and when it is atmospheric the weight of the chamber is taken by stops (not shown). During low pressure periods the pistons are coupled to a low-pressure accumulator. This change over from high pressure to low may be effected by manual or automatic (e.g. cam) means. Both chambers are heated, and the hopper 2 is heated by means of a jacket 22. The hopper outlet 7 may have an obturator which is opened by ascent of piston 10. In the Specification as open to inspection under Sect. 91, the drawings show an apparatus the premelting chamber of which is larger than the lowermelting chamber. This subject-matter does not appear in the Specification as accepted.
Patent GB-1123890-A (GB)
Title: Method for manufacturing electroluminescent gallium phosphide diodes
IPC: H01L21/208
Filed: 1967-08-03
Abstract: GaP is epitaxially deposited from a solution of GaP in Ga on to a highly polished surface of a GaP substrate.  In the embodiment the substrate is placed in a quartz boat together with a mixture of Ga and GaP.  The boat is heated to 800-1200 DEG  C. (preferably 1150 DEG C.) in an atmosphere of N2 + H2 to melt and homogenize the mixture and thus to form a solution of GaP in Ga. The furnace containing the boat is tilted to cause the solution to flow over the GaP substrate, and the temperature is maintained for 5 minutes, after which the arrangement is cooled slowly to 700 DEG  C., then more rapidly to room temperature.  Excess Ga is lapped and etched away.
Patent GB-820608-A (GB)
Title: Improvements in and relating to electric circuits controlled by light sensitive elements
IPC: H01H47/24
Filed: 1957-11-15
Abstract: 820,608. Photo-electric circuits. LONDEX Ltd. (Deutsche Londex G.m.b.H.). Nov. 15, 1957, No. 35634/57. Class 40 (3). [Also in Group XL (c)] In a circuit for controlling a relay 5 in dependence upon the state of a light-sensitive element 6, the circuit controlling the discharge tube 1 is switched to extinguish the tube after its ignition in response to the action of the element 6 at a predetermined light level to prepare the control circuit for re-ignition of the discharge tube when the light intensity crosses the level in the opposite direction. When the light intensity falling on the element 6 is above a certain value the circuit remains in the state shown. Upon the light intensity falling sufficiently, the potential of the auxiliary electrode 3 rises to trigger the main gap of the tube 1 with the result that relay 5 operates to complete a circuit for the lamp L. Relay 5 locks up over the contact of relay 7 and the change-over of contacts 5b, 5c connects the element 6 in the auxiliary electrode-anode circuit of the tube 1. Upon the light intensity rising above the predetermined value, the resistance of the element 6 falls sufficiently for the potential applied to the electrode 3 to rise and trigger the main path to operate relay 7 which releases 5, the circuit then resetting to its original state. A delay circuit 10, 11 ensures that the tube 1 does not fire due to short changes in light intensity.

Abstract: 852,426. Arresting gear for lift cages. COOK, SONS & CO. (1930) Ltd., J. Feb. 20, 1959 [Nov. 20, 1957], No. 36195/57. Class 78 (2). A device for arresting a lift cage which has over-run the normal top position of the cage comprises a tube 13 which is supported, from fixture 16, resiliently by means of spring 19 and rotatably by means of self-aligning bearings 17. The tube 13 carries sliding locking device 21 and friction collar 36. These co-operate with cylinder 53 carried by elastic rings 51 disposed in box 50 attached to the cage. Tube 13 is secured to the top end of guide cable 10 which guides the cage vertically and cylinder 53 of the cage slides, by means of collar 56, over and along the said guide cable. Operation.-The cage carries its cylinder 53, and thereby slides upwards over the cable (or cables) 10. If it rises too far, the shoulder 55 of cylinder 53 slides over lower end 12 of tube 13 and impinges at 23 upon the locking device 21. The latter thereupon slides up over tube 13 till it meets and is stopped by friction collar 36. The cage is thus brought to rest and, as it begins to fall under gravity, it begins to pull locking device 21 downwards, being caught by latches 24. The locking device 21, by reason of a one-way wedge-and-roller device 32, 33, fixes itself to tube 13 so that the cage is suspended by the said tube, the shock being taken by the spring 19. Lower stop (Fig. 6).-A tubular member 72 is secured at 70 to the bottom of the cable 10 and at 73 to the ground and carries a friction collar 36. If the cage overshoots the lower end limit, its tube 53 (see above) rides over tubular member 72 till the end 59 of tube 1 engages the friction collar 36 and so is brought to rest.
