Title: Apparatus for and method of packaging articles
IPC: B65B9/06
Filed: 1964-09-03
Abstract: 1,019,546. Testing packages. HAYSSEN MANUFACTURING CO. Sept. 3, 1964 [Sept. 9, 1963], No. 36131/64. Heading B8C. Samples of the controlled atmosphere inside a tube 27 (Fig. 1) of flexible material, enclosing articles 17, are withdrawn by a device 41, and analysed. In the apparatus described gas, for example nitrogen, carbon dioxide, pure oxygen, inert gases, cyanide or chlorine gas, or an antiseptic powder, is fed via pipes 37 into a distributing head 30 (Fig. 5, not shown), which directs the gas or powder downstream into tube 27. The web is folded in about the articles by shoes 18 (Fig. 2, not shown) mounted on a carriage 20, vertically adjustable to the size of the article. The web is pulled tightly about the articles by inclined rubber rollers 19 and a longitudinal seam is formed by heated elements 22 and compressing rollers 26. The suction device 41 (Fig. 1) has a tube 42 which extends upstream to 42a, so that samples are withdrawn from the tube 27 just before it enters a package-separator unit 28 which draws the web 12 through the apparatus. At least part of the sample is fed via filters 44, 47 to a gas analyser 52, connected to a recording device 53. The remainder of the sample or other gas may be fed along a pipe 48 to a scrubber tube 49, which sprays the gas on to the underneath side of the articles 17 before they are positioned on the web 12. A second tube, not shown, may be provided at 42a to remove excess gas from the tube so that the units are packaged at a negative pressure. The film tube 27 may be flushed with. gas before starting, so that no packages are wasted. The invention is particularly applicable to cheese and meat, which may be packaged in moisture and/or gas permeable or impermeable packaging material, or coated foils.

Patent GB-1505754-A (GB)
Title: Nuclear reactor
IPC: G21C1/02
Filed: 1975-09-03
Abstract: 1505754 Reactors WESTINGHOUSE ELECTRIC CORP 3 Sept 1975 [13 Sept 1974] 36207/75 Heading G6C In a nuclear reactor, particularly a liquidmetal cooled fast breeder reactor, the upper internals include outlet modules for channelling the coolant from selected areas of the outlet of the core vertically to the outlet plenum. The modules are composed of a highly-refractory,  high corrosion-resistant nickel-chromium-iron alloy. Each module 140 is disposed to confine and channel generally vertically the coolant emitted from a sub-plurality of core-component assemblies 121. Each module has a grid 138 with openings 136, each opening disposed to receive the coolant from one assembly 121 of the sub-plurality. The grid in addition serves as a holdown for the assemblies 121 of the corresponding sub-plurality. In the region directly over the core the outlet modules 140 are of such peripheral form that they nest forming a continuum over the core-component assemblies 121 whose outlet coolant they confine. Each module 140 includes a chimney 142 which confines the coolant emitted by its corresponding assemblies 121 to generally vertical flow between the outlet of the core and the outlet plenum. Each subplurality of assemblies 121 whose emitted coolant is confined by an outlet module 140 includes one or more assemblies which emit lower temperature coolant, for example, a control-rod assembly, or fertile assemblies, and assemblies which emit coolant of substantially higher temperature, for example, fuel-rod assemblies. The coolants of different temperatures are mixed in the chimneys 142 thus reducing the effect of "stripping" (i.e. hot-cold temperature fluctuations) on the remainder of the upper internals which are composed typically of stainless steel.

Title: Improvements in automatic dispensing machines for coffee or the like
IPC: G07F13/06
Filed: 1958-11-11
Abstract: 871,049. Coin freed and other liquid dispensing apparatus. GUITERMAN & CO. Ltd., S. Nov. 11, 1958 [Nov. 14, 1957; Feb. 27, 1958; March 7, 1958], No. 36252/58. Classes 27 and 116 In an automatic dispensing machine for coffee or like beverages, the operation of the valves 7, 11, Fig. 2, controlling the delivery from the hot water container 1 and concentrate container 9, is controlled by an electronic timing device 14 and means is provided to indicate when the concentrate container 9 is empty. The water container is provided with heating means 3 and the concentrate container 9, Fig. 7, has a U-shaped vent pipe 24, 25, on which is supported a plastic plate 27 which prevents sediment blocking the outlet and the end of the vent pipe. The operation of the dispenser may be initiated by a coinfreed mechanism by a push button, or by a photoelectric cell actuated by the insertion of a cup. The concentrate container 9 may be supported on a balance arm 15, Fig. 1, counterweighted so that when the container is empty it rocks to close a switch 17 which operates an indicator lamp or blocks the coin insert slot. In a modification the indicator lamp is operated by a photoelectric device situated at the outlet of container 9. In Fig. 8 the operation of the dispenser is initiated when a cup 31 is positioned between the elements of a photoelectric system 29, 30. The breaking of the light beam from member 29, Figs. 8 and 9, causes the cell 30 to extinguish a tube 32 which causes a relay to energise solenoids 36, 37, controlling the coffee and water discharge valves and also to initiate operation of an electronic timing circuit 11 which, after the predetermined timing period, operates a relay A1 to close the coffee and water valves. A second photoelectric cell 49, 50, operates an indicator light 52 when the coffee concentrate container is empty.

Title: Improvements in or relating to semi-automatic telephone exchange systems
IPC: H04M3/60
Filed: 1929-11-27
Abstract: 343,984. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and HAIGH, L. B., Columbia House, Aldwych, London. Nov. 27, 1929, No. 36398. Drawings to Specification. [Class 40 (iv).] In a call from an automatic to a manual exchange the number of the wanted subscriber and, if desired, the name of the calling or wanted exchange, is transmitted over an order-wire by means of a callannouncer mechanism. The number is recorded at the automatic exchange on a register associated with an outgoing repeater and such registers having stored numbers are associated in turn with the order-wire by means of a distributing switch. If the wanted line is busy, the operation of a busy key sends back a signal over the order-wire which causes the register and order-wire to be released and a busy-tone to be transmitted to the calling subscriber. The invention is described with reference to a system identical with that described in Specification 343,138.
Patent GB-156117-A (GB)
Title: Manufacture of vinyl compounds and polymerisation products thereof
IPC: C07C17/08
Filed: 1920-12-30
Abstract: Vinyl halides are prepared by heating acetylene hydrocarbons with halogen hydrides or with methyl halides under pressure.  An inert gas or liquid may be present, thereby enabling the pressure to be increased.  Apparatus is described.  According to examples:-(1) acetylene and hydrochloric acid yield vinyl chloride, (2) crotonylene and hydrochloric acid give a compound of the probable formula CH3-CH=CCl-CH3, (3) allylene and hydrochloric acid yield a mixture of b -chlorpropylene and another chlorine derivative, (4) acetylene and methyl chloride produce a compound of the probable formula CH3-CH=CHCl, and (5) allylene and methpl chloride form a mixture of the compounds CH3-CCl=CH-CH3 and CH3-C(CH3)=CHCl.  By increasing the pressure, temperature, or time or reaction, the vinyl halides are polymerized; the polymerisation may be effected without the intermediate isolation of the vinyl halide.  Vinyl esters are produced by heating acetylene hydrocarbons with aliphatic or aromatic carboxylic acids under pressure.  A catalyst may be present, e.g. mercury, magnesium, tin, copper, or their salts, iodine, hydriodic acid, boron compounds, or organic acid anhydrides.  According to an example, acetylene is condensed with acetic acid by heating under pressure in the presence of acetic anhydride, producing a mixture of vinyl acetate and ethylidene diacetate.  Instead of acetic acid, propionic acid may be employed; or the oxy, amino, chlor, or aryl derivatives of acetic acid.  Polymerized vinyl esters are obtained by increasing the temperature, pressure, or time of reaction employed for the preparation of the vinyl ester, which need not be isolated as the intermediate product.  Caoutchouc, synthetic.-Rubber-like substances are obtained by eliminating the halogens from polymerized vinyl halides, by means of sodium, zinc, magnesium, or calcium. Acyclic hydrocarbons.-By removal of hydrochloric acid from the addition products of alkylene and methyl chloride, crotonylene is obtained, together with a hydrocarbon of the formula C4H6 possessing two double bonds.

Title: A new or improved steering apparatus for motor vehicles
IPC: B62D5/09
Filed: 1929-12-05
Abstract: 344,077. Motor vehicle fluid-pressure steering-gear. GUEST, J. J., Furzedown, Knee Hill, Abbey Wood, Kent. Dec. 5, 1929, No. 37322. [Class 79 (v).] In a servo-assisted steering- gear in which the additional force is supplied by fluid pressure the controlling part and the power part have a small amount of relative motion limited by stops and are connected to the valve by speed-increasing mechanism so that the small relative movement of the controlling and power parts causes the valve to move relatively through a large amount. In the construction shown the controlling part is an arm 3 operated by the driver and rotatable about the axis 1-2. This arm can move slightly between stops 33, 34 carried by the power arm 8 which is connected at 9 to the road wheels and is fixed to a sleeve 15 having two or more vanes 23, 24 rotatable between fixed vanes 25, 26 in a cylinder 18. The arm 8 carries a pin 7 on which are freely mounted two toothed sectors 6, 10 gearing respectively with a toothed segment 4 fixed to the arm 3 and a toothed segment 12 fixed to a rotary valve 14. Thus when the arm 3 is rotated slightly relatively to the arm 8 the valve 14 is rotated to a greater extent. The valve has a central bore divided into two parts by a partition 22 and pressure and exhaust ports are cut in the valve and in the sleeve 15, the fluid flowing in the direction of the arrows shown in Fig. 1. When the arm 3 is moved counterclockwise (say) from the neutral position shown in Fig. 2 the valve is moved in the same direction through a greater angle and admits pressure fluid to the spaces 29, 30. At or about the same time exhaust ports (not shown) are opened to the spaces 31, 32, so that the vanes 23, 24 and the arm 8 are also moved counterclockwise and follow up the arm 3, the valve being closed as soon as the arm 8 has caught up the arm 3. If the power supply fails the arm 3 actuates the arm 8 positively by means of the stops 33, 34. Springs may be provided,to take up backlash and assist the sense of control. Pressure or vacuum may be employed, and an ordinary piston and cylinder may be used instead of the vanes and cylinder.

Abstract: 374,829. Automatic circuit-breakers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Dec. 11, 1930, No. 37423. Convention date, Dec. 23, 1929. Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] In electric drives for ships the oil circuit breakers controlling the generators are dispensed with and are replaced by switches which can be operated to open the circuit only when no appreciable current is flowing or to close the circuit when there is no voltage on both sides of the switch. Thus after closure of the switches connecting the generators to the propeller motor the excitation of all the generators in operation is gradually brought up to the desired value and the excitation of the generators and also of the motors, if the latter are separately excited, is taken off before the switches are opened, the switches being able to cope with the residual voltage or the current produced by it. The switches may be remotely controlled from a central control station or may be constructed as automatic cut-outs, for example, no-volt or no-current switches, being suitably adapted for use in either A.C. or D.C. systems.
