IPC: G01N15/08
Filed: 1969-11-24
Abstract: 1291497 Measuring density or porosity of moulds IRODAGEPIPARI ES FINOMMECHANIKAI VALLALAT 24 Nov 1969 [23 Nov 1968] 57334/69 Heading G1S A body 1 surrounds an air chamber 5a having an exterior water jacket 5b in which a bell jar 7 is positioned to compress air within the chamber 5a. Air from this chamber is supplied via a tube 15a and a tube 15 to a testing head 16 which is pressed on to the mould to be tested as shown, so that air passing through the pores of the mould produces a pressure variation in a tube 17 connected to pressure gauges 19, 23 which indicate the density of the mould. The bell jar has a handle 3 which when lifted raises a weighted shaft 10 Fig. 2, and lifts a valve 11 in the top of the jar to allow air to fill the jar. In Fig. 3 the test head 16 is fed by air through tube 15 via one of two differently sized rotatably selected holes a, b and the ring 32 is pressed into contact with the mould by a spring 31. The air-pressure in chamber 52 varies according to the pressure drop or air escape through the mould and the gauges 19, 23 register accordingly.

As shown, the sheet material 32 is fed over a shoulder 22 into a tube former (20) to form a tube 40 around a filler tube 18 for a plastics foodstuff. The tube is displaced via a longitudinal heat sealer 34 to a transverse heat sealer 42, the pouch so formed is filled, and displaced to permit formation of a second transverse seal 46 and severance from the tube 40. The surface treatment of the edge zones 52, 54 is in the form of printed matter at opposite surfaces of the sheet 32, which prevents adherence during formation of the seals 44, 46. In another arrangement, Fig. 7 (not shown), the treated edge zones of the sheet are provided on the outer surface thereof.

Abstract: 1408419 Television distribution systems HUGHES AIRCRAFT CO 15 Dec 1972 [17 Dec 1971] 58130/72 Heading H4R In a subscription television programme distribution system, the originating station includes a computer-controlled local processing centre LPC 16 arranged to enable subscribers to preview subscription programmes without charge and to enable viewing over a longer period upon receipt of a coded request from a subscriber. Broadcast and local-origin programmes are distributed with digital control signals frequency modulated on a 110 MHz carrier to receivers 25 where the control signals are extracted, 23, decoded, 29, and fed to a circuit 31 controlling a converter 27 permitting receipt of the programmes. A digital fine tuner 37 controls a varactor in the converter. Preview control signals generated at the LPC 16 are compared in control circuit 31 with a coded signal representing the channel selected, 35, and if a match exists the converter is enabled to permit previewing. During or after preview the subscriber may operate a key control 41 and request, 43, the full programme whereupon the channel code, subscriber address code and programme request signals are transmitted to the LPC. The subscriber's account is charged and an enable command returned to maintain the converter operative until transmission of an end-of-programme command. Restricted category programmes are only available to previously authorized subscribers so the LPC searches its memory and will only enable the converters of subscribers whose address codes are stored. Unrestricted category programmes are available after preview as above or immediately upon request at any time. Free viewing of non-subscription programmes is obtained by selection of the appropriate channels.

Abstract: 1,202,470. Jointing by rolling; making valve seatings; altering physical properties. GENERAL SIGNAL CORP. 19 Dec., 1968 [27 Dec., 1967], No. 60343/68. Headings B3A, B3M and B3V. [Also in Division F2] A butterfly valve has an annular seat receiving portion 28 formed with two shoulders 35, 36 in a valve body (21) and a coldworked metal seat ring 22 closely fitting the portion 28 under compressive loading in the radial and circumferential directions so as to be non-movable in the axial direction. A rubber strip 25 on the closure member and whose compression is variable by bolts 27 engages the seat. In an alternative construction for larger diameter valves the portion 28 is formed with an annular groove into which a portion of the seat ring closely fits. In forming the seat a rectangular sectioned rolled and welded ring is held axially by six pairs of guide rollers 182, 183 inside the cast and machined metal valve body positioned by pins 118 in holes of T-shaped rails on a stationary support 111. A carrier 122 rotatable by a variable speed motor 133 through spindles 121, 119 and splines 131, 132 therebetween has three equi-angularly spaced forming rollers 138 thereon which are biased radially inwards by springs 139 and are forced radially outwards by hydraulic rams 141 supplied by a motor 144 driven by compressed air from a supply 147. A guide roller is arranged adjacent to and either side of each forming roller which is provided with an oiler 137a. After the seat ring is sufficiently bent by rolling to be located axially by the valve body the guide rollers 182, 183 are withdrawn by releasing the spring pressure 187 by toggle mechanism 195, 197, releasing lock nut 165 and then moving the guide assembly radially inwards by a rotary actuator (166). The rolling is then continued until the final shape of the seat ring is assumed. The guide rollers 182, 183 which provide a centring bias on the seat ring and allow axial flow are mounted on arms that are connected to gears 177, 178 respectively, in the latter case by stirrup 184 and screws 185, 186 for enduring equal spacing of the rollers from the central plane 29. The spindle 119 and the carrier 122 are axially adjustable by a screw 126 bearing on a thrust bearing 125. The cold working of the seat ring increases its yield strength.

Abstract: 1330893 Gas turbine engines GENERAL ELECTRIC CO 1 Oct 1970 [2 Oct 1969] 15366/73 Divided out of 1330892 Headings FIG FIT The invention relates to a turbine shroud member and to means for supplying pressurized fluid thereto to heat the shroud member upon starting and to cool the shroud member during normal operation. The gas turbine engine assembly comprises an outer member 18 and a shroud support member 35 which define a passage 30 to which air from the engine compressor flows after having passed through the cooling passage of the combustion equipment. The support member 35 comprises upstream and downstream flange members 34, 36 formed with axially-extending rails 38, 40 which serve to support the shroud member 26. The shroud member is formed with upstream and downstream flange members 44, 46, the flange 44 being formed with a groove 48 which engages the rail 38 and the flange 46 being formed with an axially-projecting flange portion which abuts the rail 40 of the support member 35 and is secured thereto by a clamp 50. A partition member 54 is secured to the flange members 44, 46 of the shroud and defines therewith a compartment 58. The support member 35 is formed with openings 57 through which pressure air from the passage 30 flows to the compartment 56 thus serving first to heat and then to cool the flange member 36. The air passes from the compartment 56 through openings 62 in the partition member 54 to the inner compartment 58 and discharges therefrom through openings 66 in the downstream shroud flange 46 finally discharging through clearance 64 into the working fluid annulus.

An electrical measuring instrument of the permanent-magnet moving-coil type giving a long scale movement comprises an annular-cylindrical permanent magnet 1 to which polepieces 3, 4 are attached by bolts 2, the pole 3 being formed with a cylindrical aperture into which extends a cylindrical portion 6 of a core 7 attached to the polepiece 4 by a bolt 8 and thus forming an extension of the pole-piece 4. The cylindrical portion 6 is provided with an axial hole and the core 7 is cut away over an approximately 270‹ arc immediately beneath the portion 6 to allow for the mounting of a coil 12 which is capable of movement over a substantial part of the periphery of the portion 6. The construction described provides a partial remedy for losses occurring due to the reduced volume of metal available to carry the magnetic flux in the region of the cut-away portion of the core 7, these losses being offset to some extent by the provision of the projecting portion 13 where the portion 6 joins the main body of the core 7.
