Abstract: The game racket comprises a frame made from extruded metal bent symmetrically to form a substantially circular or elliptical frame portion and a pair of symmetrical shafts. In the region of the throat where the frame portion merges with the shafts there is provided an extruded metal throat-piece of which one wall completes in combination with said frame a striking area. The throat-piece has side walls formed complementary to the shafts. Holes pass through the throat-piece walls and align with holes provided in the frame and shafts and serve to receive the racket strings which draw the shafts towards the throat-piece and hold the latter under compression at the throat region.

The improvement is that the pin is cylindrical in shape and has an enlarged end, ogival in shape, and the socket has a square-section hole, the diameter of the circle inscribed in the hole being substantially equal to the maximum diameter of the swollen end of the pin.

Abstract: The process of mooring a ship at a ship's terminal, using fenders to damp forces transmitted from the ship to the ship terminal. As the ship is hauled towards the terminal by mooring winches the forces are simultaneously damped by a first counter pressure medium exerted by each fender. A second pressure medium is relieved when the pressure thereof exceeds the pressure of the first medium by discharging the second pressure medium to a pressure relief tank without effecting a recoil action on the fender.

Abstract: A trolley comprising a substantially rectangular support framework and wheels mounted on one end of support arms, the other ends of the arms being pivoted to the framework and the arms being movable to several positions so that the trolley can be used for different purposes.

Abstract: An injection nozzle for injection moulding purposes has a nozzle body with a feed passage opening which is normally closed by a needle valve. The injected resin, under high pressure, forces the needle valve to retract and open the nozzle. The improvement is a piston on the needle valve acted on by spring means to urge the needle valve to closed position, the needle valve having a valve element which, when the needle valve is fully opened, seals off the cylinder in which the piston moves, thereby to prevent entry of injection material into the cylinder. The cylinder may optionally have a charge of gas under high pressure in it, or a material which produces such a charge under the operating conditions of the nozzle.

Abstract: A dust exhausting hood is for use with surface working machines such as surface grinders. To enable the hood to remain in close contact with the surface being worked, a mantle which surrounds the working tool is connected to a mounting ring, engaged on the machine head, by guide means which permit both axial movement and tilting of the mantle of the hood with respect to its mounting ring, the mantle being constantly urged into contact with the worked surface by means of a compression spring acting between the mounting ring and the mantle. To permit maximum axial movement of the mantle, within limits, with respect to the mounting ring, the spring is a helical spiral spring which can be compressed into planar form.

Abstract: The wheels for roller skates and the like in accordance with the present invention comprise wheel bodies which have sockets provided at right and left ends of the wheel bodies and communicated through center holes with a diameter smaller than that of the sockets, two ball bearings mounted on the wheel bodies and elastic pipes inserted into the center holes, wherein two ball bearings are made with a construction in which steel balls are provided between the inner ring provided with a flange on its outer periphery and the outer ring provided with a flange on its inner periphery and these flanges are concentrically fitted in opposed position and mounted onto the outer peripheries of the flanges of the outer and inner rings, and the ends of a hub of the inner ring is fitted into the right and left sockets of the wheel bodies while being kept contact with the ends of the elastic pipes, thereby the wheels are suited to prevent backlash due to wear and tear of steel balls and outer and inner rings resulting from any

Abstract: A flash switching arrangement for a camera which includes a shutter with an opening leaf and a closing leaf and has a contact nipple and a contact shoe for the attachment of flash units. The switching arrangement includes first and second switching means electrically connected between the first contact shoe and the contact nipple respectively. First coupling means are connectible between the first and second switching means and the opening leaf of the shutter. Second coupling means are connectible between the first and second switching means and the closing leaf of the shutter. On actuation of the shutter, the opening leaf effects closure of both the first and second switching means to ignite the flash unit and after exposure, the closing leaf effects opening of both the first and second switching means.

Abstract: In continuously casting molten steel at least a pair of rolls is disposed near the leading end of the crater at which solidification of the molten steel in the cast piece completes so as to roll the cast piece at a reduction rate of from 0.1 to 2.0%. The variation in the thickness of the cast piece is detected and compared with a definite reference value for controlling the drawing speed and or the quantity of the secondary cooling water.

Abstract: A mine roof support control monitoring system in which at least some of a row of self advancing mine-roof supports at a mine face each include means for providing data relating to successive advances of that support. This data is accumulated by other means of the system and stored to give readily available indicationsof differences of actual support advances. The system preferably further includes means for pre-energizing the advance mechanisms of such supports to eliminate data relating to slack or tolerance.

Abstract: 0.degree.COLD JUNCTION COMPENSATOR PROVIDES THE ELECTRICAL EQUIVALENT OF AN ICE-BATH REFERENCE THERMOCOUPLE, AT A SELECTED TEMPERATURE, FOR EXAMPLE O.degree. C. Input connectors, for engagement with conventional thermocouple units, form thermocouple junctions with conductors connected to a battery-operated Wheatstone bridge circuit adapted to supply an equal and opposite voltage output compensating for variations in the thermocouple junction output at different ambient temperatures. The compensator may be included in a module having input sockets or input plugs to coact with plugs or sockets of conventional thermocouple units. The compensator and battery may be encapsulated, or an accessible switch may be included in the battery circuit.

Abstract: A method of manufacturing a resin concrete, where the concrete is composed of inert fillers and of thermoplastic resin. This method is characterized by the fact that the resin is used as a bonding agent and that an oxidizing additive is added to the thermoplastic resin to ensure the bonding of the resin to the fillers.

Abstract: For milling a control groove in a vehicle safety key there is used a motor-driven milling head connected by a linkage such as a pantograph to a tracer member. The tracer member follows a template groove. Since it is desired to vary the shape of the groove the template groove of the present invention is formed in sections on a plurality of strips some or all of the strips carrying several groove sections, said strips being shiftable in relation to each other so as to join up selected sections of the strips to form a single groove.

Abstract: A method for the manufacture of a starch solution in which, in the thermochemical conversion of starch using oxidizing agent and mechanical shear on the starch slurry at 110.degree. C to 180.degree. C, an amino-formaldehyde resin is added to the starch slurry before subjecting it to the mechanical shear.

Abstract: An attachment for skis, for preventing crossing of skis, includes a base plate for mounting on a ski, and a deflector which is releasably mounted on the base plate and which is pivotable thereon, under resilient biasing, from a lowered position substantially flat with respect to the base plate to a raised position upstanding on the base plate. The deflector is engaged releasably with the base plate by an axle passed transversely through the deflector and projecting therefrom at each end. The projecting ends of the axle each having a parallel sided portion of reduced width which, with the deflector lowered, can be passed into a keyhole aperture in a side wall of the base plate, whereas when the deflector is raised, the axle is retained in the aperture of the side wall. Releasable spring loading acts between the base plate and the deflector.
