Abstract: 976,253. Aerials. MARCONI CO. Ltd. Nov. 13, 1962 [April 4, 1962], No. 12954/62. Heading H4A. Energy propagated by the radio horn 2 reflected from the planar reflector 3 on to the truncated sectional paraboloidal reflector 1 to give a substantially parallel beam of radiation which beam is also substantially parallel to the planar reflector 3. Preferably the planar reflector 3 is positioned midway between the focus X of the paraboloidal reflector 1 and the horn 2. The horn 2 is preferably offset by a small angle, e.g. 6 degrees, from the normal to the planar reflector 3 to reduce the re-absorption of the transmitted energy. Side lobes in the radiation pattern are reduced by side plates extending between the edges of the paraboloidal reflector and the planar reflector (Fig. 2, not shown). The planar reflector 3 may be hinged about its line of contact with the paraboloidal reflector (Fig. 4, not shown), thus enabling the emergent beam to scan in elevation whereby the system is suitable for use as a height-finding radar.

Title: Improved adhesive-coated sheet material
IPC: C09J7/38
Filed: 1958-04-24
Abstract: A synthetic resin composition comprises an emulsion copolymer of vinyl chloride and vinyl acetate containing 95% of vinyl chloride, powdered titanium dioxide (rutile type), oil-modified condensation product of sebacic acid and polyhydric alcohol, light and heat stabilizer, diisobutyl ketone, aromatic solvent naphtha and xylol. This formulation is charged to a pebble mill and ground for 48 hours. The resulting dispersion is metred on to a carrier of aluminium foil by means of a knife coater.  The coated foil is passed through an oven at successively higher temperatures to dry and fuse the coating, which is then cooled, stripped from the foil and rolled up.  It is then used to make up a decorative sheet or tape (see Group VIII). Specification 847,815 is referred to.

Title: Slipsheeting devices for use in connection with printing apparatus
IPC: B65H39/02
Filed: 1936-04-16
Abstract: 478,478. Printing-machines. NIGRA, F. April 16, 1936, No. 13257/37. Divided out of 478,423. [Class 100 (ii)] Set-off, preventing.-In a duplicating-machine the printed sheets are delivered into a tray 73 and a slip sheet 74 is delivered by gravity on to each sheet from the bottom of an overlying stack 95. The invention is described in connection with a duplicator of the construction set forth in Specification 478,423 which is so constructed that the impression is thrown off if a sheet is not fed, and in the present application no slip sheet is delivered if the impression is thrown off owing to the absence of a sheet. The sheets 74 are formed on each side with a pair of apertures 76, 78, arranged as shown in Fig. 6, and by reversing alternate sheets a pile is formed in which the adjacent sheets have apertures 76, 78 a similar. distance apart but not in alignment. The pile of sheets is supported at each side by a pair of rollers 77 carried by a bar 79, and the bars are reciprocated in different directions to cause the rollers 77 to register with the apertures 76, 78, and so release the bottom sheet 74 which falls by gravity into the tray 73. The bars 79 are actuated by an oscillating lever 80 connected by a link 83 to a vertical lever 82, Fig. 3, which is oscillated by a bar 84 mounted between rollers 85. The bar 84 is given intermittent movements in opposite directions by means of a star wheel 86 acting on pins 87 on the bar 84. The wheel 84 is rotated intermittently by a reciprocating bar 91 formed with a hook 96 for engaging one of a series of pins 88 on the wheel 86. The bar 91 is reciprocated by the impression mechanism of the press, and stops engage the pins 88 to cause the lever 82 to come to rest in positions corresponding to the positions in which the rollers 77 release the bottom sheet 74. The hook 96 is freed from a pin 88 and fails to actuate the sheet-release mechanism if a sheet is not fed to the printing-machine. Since the sheets 74 are used repeatedly they are retained in correct order by means of a U-shaped member 101, Fig. 2, the legs 102 of which are passed through openings 103 in the sheets. Two sets of openings 103 are provided for dealing with sheets of different lengths since the legs 102 act as stops for the delivered sheets. A detachable link 104 connects the legs 102 of the member 101, and the sheets 74 are confined between the link 104 and the cross member 101a of the member 101 after the sheets have been placed over the legs 102.

A process for continuously casting phosphor bronze strands 33 comprises solidifying the molten metal in a water cooled mould 25 and then subjecting the casting to sudden cooling in a chamber 32 to induce thermal stresses that produce the effect of cold working so that after subsequent annealing the cast shape may be drawn without cracking or pulling apart. The sudden cooling may be achieved by a water spray, a spray of CO 2  or N 2  or by passing the casting through a container (38) (Fig. 2, not shown) holding dry ice.

Abstract: 1423796 Pipe couplings HOPFMA ANSTALT 26 March 1974 13326/74 Heading F2G  A valve mechanism for controlling the delivery of a liquid, e.g. beer, from a container 1 under pressure of a gas, comprises three main parts, a depending pipe, a connecting member for attaching the valve mechanism to the container and a connecting piece attached to the connecting member. The pipe 22, which extends to the bottom of the container, has a sealing cap 24 at the upper end just below which are a number of apertures 31 through which the liquid flows, and a conical socket 13 the lower end 15 of which is bent over into sealing engagement with a groove in the pipe. Apertures 20 permit the entry of the gas into the container. The upper end of the socket terminates in a rim 18 which fits into a resilient packing ring 19 seating in a recess in a collar 3 integral with the container 1. The socket and packing ring are held in place by the connecting member which comprises a nut 5 having an upper metal ring portion 7, with flat sides 6, an apron 8 depending from it and a plastics sleeve 10 having screwthreads to engage matching screwthreads in the collar 3. An elastic ring 29 in sliding contact with the pipe 22 forms the valve closure member. In the closed condition of the valve it is urged by a helical spring 26, acting through a cup washer 27, against the shoulder of the pipe cap 24 to prevent liquid flow through the pipe and also against a shoulder in the ring portion 7 of the nut 5 to prevent entry of gas into the container. The connecting piece comprises a housing 32 having a depending rim 33 with three equally spaced parts 34 depressed inwardly to pass over the flats 6 on the nut 5. By rotating the connecting piece the parts 34 pass under the lower surface of the nut to hold it in position. The housing has an inlet 45 for connection to the source of pressurizing gas. Within the housing, and sealed to it by a seal 38, slides a hollow member 37 having an integral outlet pipe 39 for the liquid. Pivoted to the housing are a pair of levers 42, connected to a handle 43, having camfaced noses 44. When the handle is moved in the direction of the arrow A the noses 44 press the member 37 downwards to slide the closure member ring 29 off its dual seatings permitting gas to enter the container to force the liquid up the pipe 22 through the apertures 31 into the outlet pipe 39.
