IPC: B27N5/00
Filed: 1969-03-12
Abstract: 1,267,952. Moulding wood/resin articles. AVM CORP. 12 March, 1969, No. 13065/69. Heading B5A. Wood flake-resin compositions are introduced into a pressure mould in a shaped envelope capable of retaining its shape when filled with said mixture prior to pressing. In this way, handling of the material and its introduction as a pre-shaped change, which pre-shaping is necessary to obtain articles having predetermined compression ratios at different regions, is facilitated. The envelope may be such as to be destroyed during the moulding, e.g. made of an uncured thermosetting resin, a cellulose derivative or a polyester, may form an undercoating to be subsequently coated, e.g. made of paper impregnated with phenolic resin, or may form a laminated final coating on the article, e.g. made of veneers or melamine impregnated paper layers.

Title: Improvements relating to vehicle direction indicators
Inventor: SMITH EDWIN
IPC: B62J6/00
Filed: 1948-05-15
Abstract: 654,448. Road-traffic signals on vehicles. SMITH, A. E. May 15, 1948, No. 13356. [Class 118 (ii)] A vehicle direction indicator more particularly for bicycles comprises two articulated parts which in the out-of-action position are folded against one another under spring tension and on release automatically move into alignment and project outwardly as in the Figure. A battery casing 16 is pivoted on pin 15 fixed to the clip 10 which is clamped to the handlebar 11. A coil-spring 28 presses casing 16 in a clockwise sense against bracket 14a. The indicator arm 23 having transparent sides 23b is mounted on the pivot-pin 22 carried by the end cap 16a and is pressed into alignment with the casing 16 by spring 29. Cap 16a is detachably held by a bayonet fitting to permit insertion of a standard dry battery into casing 16 where the far end contacts the casing through spring 30 (Fig. 8, not shown) which also presses the near end into contact with an insulated terminal pin 18. In the operated position, as shown, a projecting member secured by pin 18 contacts a corresponding projection on the indicator arm 23 insulated from the frame thereof but connected to the mounting 26a for a lamp 26. The other terminal of the lamp 26 is held in contact with the strip frame 23a which completes the circuit to the battery and thus the lamp is lit. To restore the indicator to the out-of-action position the casing 16 is turned anti-clockwise and the arm 23 folded back alongside the casing (thereby breaking the lamp circuit) and the tip of the arm is located on bracket 14a which retains the device in the folded condition (Figs. 3 and 4, not shown). To operate the indicator pressure is applied to a raised portion 16e on the right-hand side of the end of casing 16, causing the tip of the arm 23 to leave bracket 14a whereon springs 28, 29 re-assert the projected position shown, the lamp 26 lighting automatically. The indicator may comprise more than two articulated sections, each junction having spring means for alignment. The lamp 26 may be replaced by a reflector disc at the end of the outer section.

Abstract: 1,007,244. Capless electric lamps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 4, 1964 [April 4, 1963], No. 13426/63. Heading H1F. [Also in Division H2] A capless lamp has a sealed envelope terminated at one end by a pinch seal which provides a base for the lamp, with a vitreous exhaust tube projecting from the pinch seal and supporting a body of vitreous material within the envelope, the base of the exhaust tube communicating with the interior through an opening in the body and each lead-in conductor to the or each filament being supported by the body and extending through the pinch seal to form an electrical terminal adjacent the outer surface. In one form, having two filaments 3, Fig. 1, the lead-in wires 4 are sealed through a glass block 7 supported by the exhaust tube 8, which is sealed through the pinch 2. In a modification (Fig. 3, not shown), the block is formed by the shaped end of a tube coaxial with and overlapping the exhaust tube, the end of the tube being sealed in the pinch. The tube 11, Fig. 5, may, alternatively, have a flared skirt 12, for deflecting internal convection currents away from the pinch when the lamp is used base upwards. The tube may support a stem into which support members 10 for the filament may be sealed. Fuses 13 may be housed in the interior of the tube. In all cases the vitreous body has an orifice 14 communicating with the exhaust tube. Specification 797,441 is referred to.

IPC: B63B21/56
Filed: 1917-09-22
Abstract: 119,097. Strathern, H. Sept. 22, 1917. Towing. - In a reresilient coupling-defor marine and other towing connexions, the parts are arranged so that the oil or other fluid in the cylinders is forced from one side of the piston to the other. The coupling hook 22 is attached through a bow piece 21 to a cross-head 20 connected to the rods 16 of pistons 14 having non-return valves and sliding in cylinders 6, which are supplied with oil from a tank 1 through the pipe 3, valved casing 4 and passage 5. The opposite ends of the cylin. ders are connected by a passage 7, and the central portions have pipes 9 leading to a valve box 10 below the tank 1. A pull on the coupling hook moves the pistons 14 and forces oil into the tank until the pistnns cover the entrances to the pipes 9. Spring- loaded pistons 33 may be fitted to the cylinders to form cushions. When the pistons return, the oil passes through the valves 15. The return is caused by springs 25 connected to the cross-bar 20 through a chain 24 passing around pulleys 27, 28. The recoil may be effected by compressed air, steam, or other means.

Abstract: 499,107. Liquid-meters; fluid-actuated valves. FOLKES, G. E. May 7, 1938, No. 13663. Convention date, May 8, 1937. [Classes 69 (i) and 135] In a liquid-metering apparatus comprising a large meter 3 for measuring a large flow and one or more smaller meters 4, 5 for measuring the flow when it is smaller together with a counting or indicating mechanism 7 common to the meters, each meter is coupled to the indicating mech anism through a one-way or free-wheel clutch 32, 42, 52, so that the mechanism is operated at any time by the meter running at the highest rate. In the form shown the meters are arranged in series in the pipe line, and the smaller meters 4, 5 are respectively short-circuited by the opening of valves 44, 54 in branch pipes 43, 53 when the flow rises above their capacities. Fig. 3 shows a fluid-operated valve which may be employed, comprising a slide-valve 11 operated through a snap-over device 13, 14, 15 by a piston 12 subjected to the pressure of the fluid. Alternatively, a spring-pressed valve opened by the fluid-pressure and presenting a greater area to the pressure when open may be employed. In another arrangement described the meters are arranged in parallel branches of the flow pipe, a hand operated four-way cock allowing the flow to be diverted to any one of them.
