Abstract: 1,181,048. Container closures. Z. M. ROEHR. 26 Nov., 1968 [18 Dec., 1967], No. 56073/68. Heading B8T. A tamperproof closure, e.g. of polypropylene or polyethylene, has a lower skirt 7 joined to the side wall 3 of the closure by means of bridges 9 between which are gaps (11), Fig. 3 (not shown), through certain of which project tongues 23 formed on a container 13 to which the closure is applied. In order to open the container the closure has to be rotated thereby causing the tongues to shear the bridges 9. The closure is assembled on the container by downward pressure causing a part 25 to slide over the tongues, both the lower skirt 7 and the tongues yielding resiliently until the tongues enter the gaps 11. The bridges 9 may be unequally spaced; and one bridge may be so positioned that it is not sheared. Again, Figs. 5-8 (not shown), a screw cap having similar features may be applied to a container having a pair of hookshaped tongues (30) on its neck.

Apparatus for inspecting a continuously moving fabric web a comprises a mirror 1 supported for rooking movement relative to the path of the web a and a viewing position E and which is rocked to and from a datum position (full line position) in such a manner that it moves from the datum position to follow the movement of the web a for a predetermined distance (to the broken line position) and is then returned with a quick return movement so that an eye at the position E observes in the mirror 1 a stationary image of overlapping successive positions of the workpiece, and spring means 12, 13 is provided to absorb shock resulting from the quick return movement of the mirror 1. The mirror 1 is fitted to a frame 2 fixed to a shaft 3 rotatably mounted in the machine frame 4. A roller 6 carried by an arm 5 secured to the shaft 3 cooperates with a groove 8 in a cam 7 to move the mirror 1 clockwise from the full line position to the broken line position and anticlockwise from the broken line position to the full line position. The web a is inspected whilst passing between rolls 9, 10 and the frame 2 is oscillated in synchronism with the linear speed of the web. To prevent or reduce vibration of the frame 4, a rod 11 is pivoted to the roller-carrying end of the arm 5 and passes freely through a bracket 4a secured to the frame 4. Shocks resulting from the quick return of the frame 2 are absorbed first by a spring 12 and then by a stronger spring 13. In modifications (not shown), the springs means are not limited to two stages, e.g. strong and weak spring of different spring constants may be used or a single spring may be used to work through a plurality of stages.

Abstract: 1293765 Drinking cups A P AUGUSTINAVICIUS 19 Nov 1969 [11 Dec 1968] 56529/69 Heading A4A Disposable thin walled insulating receptacles having a side wall 9 tapering down to the receptacle bottom 11 e.g. cups, boxes, dishes, trays, cartons, buckets, canisters, and protective enclosures for shipping, and which may be circular, triangular or rectangular in section, are moulded from pre-expanded polystyrene beads e.g. of 101b/cu. ft. density, which are heated within a cavity defined between mould parts, one or both whereof are movable, which is then decreased in volume to compress and fuse the beads together to produce, by combined compression and shear, an interfused boundary between adjacent beads which is at an acute angle to a plane T-T transverse to the side wall, and an overlapping, Fig.4, of the fused beads in opposite directions at the inner and outer side wall surfaces, resulting in decreased permeability. On tearing the side wall transversely, the rupture occurs along the interfused boundary. When the moulding cavity is defined between unitary core and cavity parts, the density of the container bottom exceeds that of the side wall, but these densities may be equal or otherwise varied using an independantly displaceable cylindrical moulding plunger at the narrow end of the cavity part to effect independent compression of the base. The receptacles may comprise side wall thicknesses of up to 0À200 inches but the preferred embodiment relates to a circular section drinking cup, which is suitable for stacking in automatic vending machines, and which may be provided with a lip facilitating the application of a closure, and wherein the side wall taper is 8 degrees and the thickness is from 0À010 inch to 0À080 inch, preferably 0À035 inch to 0À045 inch.

Filed: 1969-11-25
Abstract: 1,272,657. Greenhouses. S. O. ZEILON. 25 Nov., 1969, No. 57550/69. Heading E1A. [Also in Division F4] In apparatus utilising a continuously collapsing foam for thermally insulating a body, e.g. a cold storage room, green house or building, or for insulating articles and goods to be transported in movable containers, a gas is introduced into a solution of a foaming agent in a liquid to produce the foam which is passed into an insulating space 3 formed between walls 1, 2 and the liquid formed in the space by the continuous collapse of the foam flows to the bottom 5 of the space and is collected in a sump 10 and has further gas introduced thereto to produce additional foam which is returned to the insulating space. The foam generating means comprises a liquid nozzle 30 and propellor 27 which passes the foam to an upper header tube 11 under the control of a pressure gauge 25 and the liquid may be heated or cooled in the collector 10. The inner wall is impervious and the outer wall 1 permeable to allow the gas to exhaust, the wall being supported by the foam in the space 3. Examples of the liquids, surface active agents and foam stabilizers are described. In a modification, the insulating space may be divided into layers, each having a different type of foam or foam at different temperatures may be used, (Fig. 3) which are achieved by a heat pump comprising a compressor, evaporator and condenser which transports heat from the liquid to be cooled to the liquid to be heated. It is stated that the insulating system allows absorption and accumulation of the heat of the sun during the day, which heat is utilised during the night to heat the insulated building or house.

Title: Cycloconverter interface apparatus
IPC: H03M1/60
Filed: 1970-12-04
Abstract: 1329560 Pulse and sawtooth wave generators; pulse frequency modulation GENERAL ELECTRIC CO 4 Dec 1970 [5 Jan 1970] 57844/70 Headings H3T and H4L An interface circuit for coupling the source of a modulation signal 71, Fig. 2, of varying amplitude and polarity, to a cyclo-converter frequency and phase sequency control input, comprises, Fig. 1, a circuit producing a pulse train (second or third line, Fig. 2), having a repetition frequency proportional to the absolute amplitude of the modulation signal, together with a binary signal (last line, Fig. 2) indicating the sign of the modulation signal. The modulation signal is thus applied at 11 to two inverting operational amplifiers 15, 17, 19 and 21, 23, 25 to produce equal amplitude but opposite polarity versions of the modulation signal at the drain electrodes of respective FET's 27 and 29. These are alternately gated to alternately pass opposite polarity (except at a sign transition C) signals to an integrator 31. As shown, FET 27 initially conducts and a negative voltage sample of the signal 71 is applied to the integrator such that its output rises (the integrator also acting as an inverter) until a positive threshold (+), as set by differential comparator 37 and Zener diode 49, is reached (a), when the comparator produces a pulse which when applied to switching logic 39, causes said logic to switch conductance from FET 27 to 29. The sample now applied to the integrator is equal in amplitude to the previous, but of opposite sign. The integrator output thus goes negative until a negative threshold (-), as set by comparator 35 and Zener diode 55, is reached (b). Comparator 35 similarly then produces a pulse for logic 39 to cause a second conductance switch. The integrator output continues to oscillate between the two thresholds and a conductance switch is caused at each threshold attainment. The increase in the amplitude of signal 71 at B causes an increase in the slope of the integrator output and an earlier threshold attainment at d. A "180 degree" change in phase of the integrator output is caused by the change of sign of signal 71 at C. The FET switching signals serve as the output of the interface circuit. A differential comparator 13 compares the sign of signal 71 with that of the common line 57 and gives a I signal (bottom line, Fig. 2) when the signal 71 goes negative. The sign indicating signal is fed to logic 39 which supplies a "count up" (CU) or "count-down" (CD) signal to the cycloconverter as necessary.

Title: The Profiling of Workpieces.
IPC: B21B19/12
Filed: 1967-01-10
Abstract: 1,177,639. Dividing. ROTARY PROFILES ANSTALT. 10 Jan., 1967 [10 Jan., 1966; 5 April, 1986; 5 May, 19661, No. 58197/66. Heading B3W. A method of parting a ring from a tube comprising rolling a progressively deepening groove in the tube with profiling means which, as rolling proceeds, presents to the tube profiling portions of progressively increasing height and decreasing width. A machine for carrying out the method has a mandrel 20 which projects from each end of the tube and a roller carrying a number of annular inserts 28 which indent the tube, either cutting completely through the tube or leaving a thin easily broken web. The mandrel has a smooth cylindrical surface or, if the tube is sufficiently robust, has projecting collars 32 which indent the inside of the tube opposite the indentations produced by the tools 28. To accommodate the axial extension of the tube as it is indented the inserts diverge from their leading ends as shown in the developed view, Fig. 5. Cutting is completed in one revolution of the roller. The mandrel ends projecting from the tube are supported by one or two rollers, Figs. 1 and 2 (not shown). The cross-sectional shape of the inserts is not uniform and changes from a round blunted crest to a sharp edge, Fig. 8 (not shown). In a modification the profiling formation is arranged as a constant pitch helix around a cylindrical body, the tube moving axially relative to the cylindrical body. The tube may be supported by a solid mandrel, or by a mandrel which has recesses cut into it to receive barrel-shaped rollers, only the rollers contacting the inside surface of the tube, Fig. 11 (not shown). In a further modification, the profiling formation consists of circular discs arranged in radially directed slots formed in the periphery of the wheel. Each disc is rotatably supported in its slot by a pin which is transverse to the axis of the wheel and is tangent to a pitch circle which is common to all the pins. The tube travels in a direction tangential to the wheel and is indented at successive positions by the discs which have double-chamfered edges.

In the gun of Fig. 10, provided for end welding, centring is effected by an expanding mandrel 11 which is co-rotatable with a welding head 31 and comprises sets of balls 20, 22 disposed between an enlargement of a rod 19, a sleeve 21 and the mandrel body. The head 31 carries one or more electrodes 33. Rotation of a knob 15 acts, via pegs 16 engaging helical cam slots in an assembly 17, to axially move the rod 19 and cam the sets of balls outwards into engagement with the workpiece tube bore, the engagement allowing rotation of the mandrel. Axial adjustment of the tip of the electrode with respect to the workpiece is by rotation of a part 34 in oppositely-threaded screw engagement with the gun body 26 and an abutment member 14 engageable with the workpiece plate 13 the member 14 comprises a transparent quartz tube 40 for welding observation. The extremity 32 of the head 31, together with the electrode, is interchangeable in order that the electrode angular and radial position may be varied. Shielding gas is directed to a welding chamber 39 through a stationary inlet port 37 and rotary conduits 38. Cooling water is circulated through a stationary inlet port 41, rotary conduits 43 and a stationary outlet port 45. Welding current is passed to the head 31 through a stationary cable 45<SP>1</SP> in the interior of the port 45 and a mercury filled channel 46. A pulse transmitter which may be provided for monitoring and controlling automatic operation, comprises a permanent magnet 28 fast on a shaft of the speed reducing gear and co-operating with two separated spring blades in a bulb under vacuum. In the gun of Fig. 11, provided for internal welding, centring is by a member 51 (shown in two different forms) and/or rings 52, 53.
