Inventor: RICHARDS DAVID OWEN
IPC: C08J7/052
Filed: 1967-03-13
Abstract: 1,166,146. Plastics - cellulose laminates. BRITISH SIDAC Ltd. 10 June, 1968 [13 March, 1967], No. 11620/67. Heading B5N. [Also in Divisions B2 and C3] A film of polyethylene is applied by melt extrusion to one side of a film of regenerated cellulose which has been coated with a coating composition comprising (a) 2-40% of an aqueous suspension of a vinylidene chloride copolymer and (b) 98-60% of a solution of a vinylidene chloride copolymer in a volatile organic solvent (see Division C3).

Title: Improvements relating to the manufacture of tubes
IPC: B21D5/01
Filed: 1956-04-17
Abstract: 799,267. Angular bending. KOCKS GES., F. April 17, 1956 [April 25, 1955], No. 11678/56. Class 83 (4). A method of making longitudinal slit tubes from strip comprises feeding the strip between a pair of jaws which together form a pass of gradually decreasing cross-section, the jaws being driven in such a manner as continuously to open and close and simultaneously to advance the strip in steps. Jaws 1, 2 which are carried by eccentrics 3a, 3a<SP>1</SP> and, through links 5, 5<SP>1</SP>, eccentrics 6a, 6a<SP>1</SP>, form a pass of gradually decreasing cross-section. Strip 7 entering the pass is deformed and fed forward a step every time the jaws 1, 2 close, upon rotation of the eccentrics, thus to form a tube. The jaws 1 may have a projection 14, which engages in the slot formed when the strip is bent into a tube, for longitudinally guiding the strip. The jaws may each be made in three parts 8, 9, 10 and 11, 12, 13 of which the intermediate parts 9 and 12 are changed to form a tube of different diameter.

Title: Improved mounting for the reproducer of a talking machine
IPC: G11B3/00
Filed: 1933-04-21
Abstract: 418,373. Gramophones. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, BROWN, W. J., Danesmoor, Harefield Road, Uxbridge, both in Middlesex, and WHITE, J., 26, Connaught Gardens, Palmers Green, London. April 21, 1933, No. 11759. [Class 40 (ii).] The arm 15 carrying the sound reproducer or pick-up 16 of a gramophone is mounted so that a loaded spring may maintain it in a raised position when required, for needle changing &c., the spring being completely uninfluenced by such limited vertical movements of the pick-up arm as occur during playing. The arm is of generally inverted channel section and has a pivot 18 which passes through a slot 12 in a member 9 mounted on ball bearings 6, in a base 1. The member 9 is permitted limited angular movement, e.g. by a screw 14 engaging in a horizontal slot in a tubular part 3 of the base. A tensioned spring 22 tends to maintain the pin 18 at the lower end of the slot 12, but when the arm 15 is raised into a vertical position, a recess 21 in the arm engages over a lug 11 on the member 9, the spring being further tensioned during this movement by the passage of the cam projection 20 across the lug 11, and thus maintaining the arm in its raised position. The arm may be moulded from a phenol formaldehyde condensation product and may be integral with the pick-up casing.

A.].-(Schiele & Bruchsaler Industriewerke Akt.-Ges.; Baden-Baden, Germany) April 17, 1935, No. 11807. [Class 38 (v)] In a switch in which energization or de-ener. gization of a magnet b, by means of pushbutton or like switches, causes a contact member e to move into the closed or open position provision for overload is made by making the member e slidable rela tively to the armature a and arranging a com pression spring c<1> be tween the two mem bers ; the two mem bers are normally held latched with the spring c<1> compressed but the latch is released on overload, allowing the spring to expand to break the circuit. The member e is fixed to a rod d which slides in a tube c fixed to the armature a and links h, h<1> are pivoted to the tube and rod, the link h being normally held in the position shown by a latch f. On overload, an electromagnetic or thermal device g trips the latch f, the spring c<1> expands moving the contact member e into the dotted position. This breaks the circuit of the magnet band the armature a falls until it encounters a stop (not shown) and the member e encounters a stop i. In resetting, a manually operated member (not shown) raises the members d, e till the contact member is again latched to the armature. Further operation of the manual member or the energization of the magnet b restores the parts to their original position.

Class 39(i) [Also in Group XL(c)] A mixer comprises a thermionic diode valve having a rod shaped cathode 9 surrounded by a cylindrical anode 13, the diode constituting a coaxial line coupled to and forming a path between an input wave guide to which the microwave signals to be mixed are applied and an output wave guide. The valve may be filled with xenon or evacuated and the transit line of the electrons is appreciably greater than the period of one cycle of the operating frequencies. Either 1 or 2 may be the input guide and the other the output guide, the guides being coupled to extensions of the cathode, a window being provided for the purpose in the left hand end of the anode. The cathode diameter is rapidly increased at 11, 12 to nearly that of the anode and is active only over the portion between the guides. The anode is preferably operated at a negative potential provided through connections to the valve base (not shown) at the left hand end. The anode may alternatively be supported by a wire passing through the side of the glass envelope 4 in which case the wires may form the anode connection and the portion of the anode beyond the guide 1 being omitted. The guides are matched to the valve by pistons 15 and slotted rings 17. prevent lateral leakage of energy.

Title: Improvements relating to pneumatically operable bells, gongs or the like
IPC: G10K1/068
Filed: 1922-04-29
Abstract: 200,618. Irwine, H. G. April 29, 1922. Bell strikers; bell-operating mechanism, pneumatic; rod and tube vibrators.-In a pneumatic bell or gong, particularly for household use, a fingeroperated pumping apparatus comprising a spring-controlled piston 4 moving in a casing 1, is combined through a flexible tube 3 with a cylinder 11 containing a plunger 10 which, in response to the operation of a pressbutton 6, is propelled upwards to strike the sounding-member 12, the plunger, by its movement, uncovering a small air-release hole 14 in the side of the cylinder thus ensuring a sharp blow. A cushioning-spring 17 may be providad. In modifications, the cylinder and plunger are mounted inside the dome 12, which may be mounted on a reasonance box. In order to exclude dust from the cylinder 11, the plunger 10 may carry a fixed or loose cap 15, Fig. 7, which may be provided with a metal striking disc. When a number of bells are arranged in the same casing, each is provided with an indicator comprising a ball 20, Fig. 4, of cork, wood, thin metal &c., mounted on the end of a blade spring 19 and set into oscillation by the movement of the plunger. A slot 23 in which the spring 19 moves, may also act in place of the release aperture 14. The spring 19 is mounted on the plunger 10 by means of a concave-faced nut 21 on an apertured shank 20a, Fig. 7, so as to adjust the normal position of the ball 20. In the form shown in Fig. 7, the indicator is normally above the cylinder, a pin 30 on the plunger registering with a slot in the cylinder to prevent displacement of the plane of vibration of the indicator. In other modifications, a number of plungers and cylinders may co-operate with the same sounding-member which as an alternative to the bell-dome 12 may comprise a horizontal tube, rod or helical wire, or a convolute spring having a flat extremity. The Provisional Specification also describes modifications in which an air-release aperture in the casing 1 assists the return of the piston 4; the indicator may be operated by the compressed air through an airrelease aperture or through an additional branched cylinder and piston, whilst a single movement of the plunger may produce a double blow on the bell by means of a pivoted bifurcated member, or a multiple blow by means of a rack and pinion operating a striking arm.
