Title: Method of manufacturing articles by joining preformed shapes
IPC: B29C65/52
Filed: 1973-10-26
Abstract: 1460461 Seaming non-metallic sheet material J W ELLEMOR 26 Oct 1973 [30 Oct 1972] 49911/73 Heading B5K Two preformed shapes are joined by bringing the shapes into close proximity, introducing adhesive into the gap between the shapes, and rotating the shapes to distribute the adhesive through the gap by centifugal force. Preferably, the shapes are hollow bodies each having a circular annulus in the region to be joined to form a sphere, an ovoid, a cylinder or an ellipsoid. The shapes may be made of plastics, metal, glass, wood, sand or stone material and specified adhesives contain a cyanoacrylate, a methyl cyanoacrylate or an isocyanoacrylate and set into a thin film between two surfaces. The adhesive may be applied to the shapes before or after the commencement of rotation thereof. Adhesive may be applied from a container positioned within the cavity formed by the shapes and which is actuated by rotation or a remote signal to spill or eject a predetermined amount of adhesive which is forced into the gap. In one Example, two hemispherical acrylic shapes are joined to form a sphere using a chemically catalysed acrylic cement. The edges to be joined are of equal diameter and are bevelled so that when the hemispheres are placed together an outwardly converging gap is formed. A band having a pressure sensitive adhesive thereon is placed around the outer periphery of the gap to hold the sphere together. A tube is passed through an aperture at the pole of one of the spheres to deliver a predetermined amount of cement into the gap. The assembled hemispheres are rotated to distribute the cement through the gap and the rotation is continued until the cement sets sufficiently to hold the hemispheres together. In another Example, collars are provided to apply axial force to the hemispheres at their poles to force them together.

Title: Magnetic core storage device
IPC: G11C11/08
Filed: 1963-12-18
Abstract: 989,774. Magnetic storage devices. AMP Inc. Dec. 18, 1963 [Jan. 4, 1963], No. 49926/63. Heading H1T. A multi-aperture core 1 (Fig. 1) of rectangular loop magnetic material stores, e.g. a binary " 0 " when the remanent magnetic flux in the core is all clockwise in direction (the " clear " state, Fig. 2, not shown) and stores a " 1 " when the direction of the remanent flux around the edge of main aperture 2 is changed to anticlockwise (the " set " state, Fig. 3, not shown), an indication of the information stored being obtained by applying a limited radio frequency alternating current to a read-out winding 8 which passes through read-out aperture 4 twice as many times as it passes through main aperture 2. If a " 1 " is stored the flux around aperture 4 reverses with the alternations of the current in winding 8 and produces an output in the similarly arranged winding 9 sufficient to energize a lamp 10 or other indicator. Information can be transferred from the core 1 via an output winding 12 by reversing the flux round aperture 5 when the core is in the " set " state by a pulse in a priming winding 11 and then energizing the advance winding 13 to return the core to the "clear" " state. A holding winding 14 linking 5 prevents spurious signals in winding 12 from affecting the core. Parameters of an exemplary device are given. Specifications 899,366 and 899,367'are referred to.

Abstract: 1,183,860. Stencilling apparatus. McCORQUODALE COLOUR DISPLAY Ltd. 20 Sept., 1968 [2 Nov., 1967], No. 49938/67. Addition to 1,053,663. Heading B6C. A stencilling apparatus, of the kind comprising a container for a liquid, with an outlet covered by a mesh screen stretched over a stencil plate, incorporates means for producing a sub-atmospheric pressure at the back of the screen, so that gravitational flow of liquid from the container to the face of the screen may be reduced or stopped. Tubes 6 supply liquid to the compartments 2 of container 1, which co-operates with frame 4 and cover 5 to form a closed space. Tube 7 is connected to a suction means such as a vacuum pump. When cocks in the tubes 6 are closed and the suction means operated pressure in the closed space may be reduced. During a halt in stencilling the flow of liquid to the screen face may be reduced substantially to zero. Preferably controls for the reduced pressure which has this effect are operated automatically if the printing machine of which the apparatus is part stops, or if suction-operated feeding grippers fail to grip or to grip and feed a sheet which is to be stencilled. During stencilling a pressure above atmospheric may be created in the closed space to increase the flow of liquid.

Title: Means for taking ground measurements
Inventor: UPTON PHILLIP SCOTT
IPC: G01C7/04
Filed: 1965-11-26
Abstract: 1,108,879. Ground contouring apparatus. INERTIA SWITCH Ltd. Nov. 7, 1966 [Nov. 26, 1965], No. 50438 /65. Heading G1F. Apparatus for measuring irregularities in ground surfaces comprises a framework adapted to be secured to a vehicle capable of traversing the ground to be surveyed, a wheel 3 to follow the contour of the ground and to operate recording means and a damped pendulum 12 to compensate for the effect on the recording means of vertical movement of the vehicle as it traverses the ground. The wheel 3 is carried by a pivot arm 4 and is held in contact with the ground by the action of a spring 5. A flexible cable 8 transmits vertical movements of the arm 4 relative to the framework 1 to a film carrier 11 by way of pulleys 9, 10 so that the carrier 11 is moved vertically in response to movement of the wheel 3. The pendulum 12 is mounted on a horizontal spindle 13 and carries an aluminium alloy vane 15 which runs between two permanent magnets 16 to provide eddy current damping. The pendulum is balanced by two springs 17 and the arrangement is such that with the vehicle driven above a determined speed the pendulum will remain stable as the vehicle traverses the ground thus compensating for the vertical movement of the vehicle. Two mirrors 19, 20 are carried by the spindle 13 and light from a lamp 21 is reflected by these mirrors on to mirrors 24, 23 and thus to the film carried by the carrier 11. Vertical movement of the beam of light impinging on the film is thus representative of the actual vertical movement of the wheel 3. The mirror 23 is cam actuated to cause the light to sweep over the film and then fly back to its starting position and the mirror 24 is ratchet actuated to tilt the beam of light after each fly-back so that a number of traces can be accommodated on each film. The film is preferably of the self-developing kind and traces representing the contour of the ground traversed are developed on the film. In an alternative embodiment the optical arrangement is replaced by an electro-mechanical transducer one part of which is carried by the pendulum 12 and the other part of which is actuated by a cable secured to the arm 4, the output signals of the transducer being used to provide a record on magnetic tape.

Title: Pressure proportioning valve assembly for hydraulic brake systems
IPC: B60T8/26
Filed: 1970-10-27
Abstract: 1283908 Hydraulic systems; modulating valves; differential braking; valves MIDLANDROSS CORP 27 Oct 1970 [6 Nov 1969 15 July 1970] 51069/70 Headings F2F and F2V A proportioning valve assembly 10 is interposed between a master cylinder 12 and the rear wheel cylinders 24, 26 of an automobile dual hydraulic braking system and is actuable to establish a pressure differential between the rear wheel cylinders 24, 26 and the front wheel cylinders 18, 20 in the higher range of pressure applied by the master cylinder 12 and to increase the pressure differential at a linear rate as the master cylinder pressure increases in such higher range. The valve 10 comprises an inlet port 34 and an outlet port 40 and fluid flow therebetween is controlled by an annular valve element 50 having a passageway 111 therethrough and an annular seat 115, and a piston 48 with a lip postion 98, the piston 48 being movable against the action of a coil spring 124 to cause engagement of lip portion 98 with the seat 115 and thereby cut off communication between the inlet port 34 and the outlet port 40. When the brake pedal 14 is initially operated identical pressure is applied at the front cylinders 18, 20 and the rear cylinders 24, 26. The communication of the master cylinder 12 to the rear cylinders 24, 26 through the assembly 10 comprises a passageway 60, a portion 58 of a stepped bore 32 in the valve body 30, a passageway defined between a central portion 82 of the piston 48 and the wall of the passageway 111 through the valve element 50, a reduced diameter portion 52 of the stepped bore 32, and passageways 96 and 54 to the outlet port 40. The passage ways 96 are formed between angularly spaced projections 94 on a head portion 92 of the piston 48; the central portion 82 of the piston 48 has flat sides (84, 86) joined by arcuate surfaces (88, 90) and the piston 48 also includes a radially extending flange portion 100 having flat sides (102, 104) coplanar with flat sides (84, 86) and arcuate surfaces (106, 108) concentric with but greater in diameter than surfaces (88, 90), Fig. 3 (not shown). As increasing force is applied to the brake pedal 14 a point will be reached where the pressure in the stepped bore 32 moves the piston 48 downwardly against the bias of the spring 124. When the tip portion 98 comes into engagement with the sealing surface 115 communication between the inlet port 34 and the outlet port 40 is interrupted. Increased master cylinder pressure acting on the piston 48 will now cause communication to be reinstated. In this way the lip portion 98 opens and closes against the sealing surfaces 115, thereby modulating the pressure at the outlet port 40 so that the pressure at the outlet port 40 increases at a lower rate than the pressure applied by the master cylinder 12.
