Title: A core making method and apparatus
IPC: B22C9/12
Filed: 1982-04-13
Abstract: Moulding sand containing water-soluble binder is charged into a core box, constituted by two patterns (11,23) assembled together, to form an unhardened core (33). Then, the patterns (11,23) are moved apart so that the unhardened core (33) is left on one of the patterns (23). This one pattern (23) is then placed on a table (18) and a cover box (27) is placed over the unhardened core (33). Heated compressed air is introduced into the cover box (27) so that the air permeates through the unhardened core (33) from the exposed surface of the latter and is vented to atmosphere via vent holes in the pattern (23), to dry and harden the core in a short period of time. <IMAGE>

Title: Guided missile system
Inventor: RAYNAUD JACQUES
IPC: F02K9/80
Filed: 1982-05-27
Abstract: A missile to be launched at low speed from a tube and equipped with a propellant system of the combustible propulsive charge type is characterised in that the propulsion system (1a, 1b, 2) is determined and positioned so that it can furnish the missile I at one and the same time with axial propulsive thrust and the forces for manoeuvring under powered guidance, so that the variation of position of the centre of gravity G of the missile I along its axis L - L as a function of the combustion of the propulsive charge is such that, at the exit of the missile from tube 7, the centre of gravity G passes through the line of action of the said manoeuvring forces and so that, during flight, generative torques of aerodynamic incidence are allowed to occur producing manoeuvring forces adding to those of powered guidance. The missile may be used with an anti-tank weapon system. <IMAGE>

Patent GB-2108636-A (GB)
Title: Check valve
Inventor: GOODMAN ROBERT BERNARD
IPC: F16K15/06
Filed: 1982-10-08
Abstract: A low pressure drop check valve includes an apertured, streamlined guide body (45) mounted on struts (40). Forward flow through the valve unseats the valve member (35), which receives therewithin a face (50) of the guide body allowing streamlined flow around the valve member and guide body. Reverse flow is accommodated by apertures (60) and (65) in the guide body, flow through the apertures being applied to an inner surface of the valve element, thereby seating the valve element for blocking such reverse flow. The check valve is also provided with damping means (70) and (85) for minimizing valve element oscillation and bounce. Maintenance of the valve in an open condition is enhanced by maintenance of a low pressure region downstream of the poppet. The struts (40) extend in directions with a component tangential to the guide body, as shown in Fig. 2. to accommodate thermal and fluid loading. <IMAGE>

Title: Improvements relating to the measurement of directional wave spectra
Inventor: ANDREWS WILLIAM BANHAM
IPC: G01C13/00
Filed: 1982-10-13
Abstract: A system for evaluating data related to directional wave spectra includes a range finder (Figure 1a) for evaluating the range of the sea surface from a fixed reference position in at least three different directions fixed in space. The range measurements R1, R2, R3 are used to generate electrical signals related to the elevation and the angles of pitch and roll of the sea surface from which the directional wave spectra are computed. The range finder includes a transmitter Tx and a receiver Rx arranged to scan a beam of pulsed IR radiation along a closed path at the sea surface. The elapsed time proportional to range, between transmission of a pulse and reception of a corresponding return is evaluated periodically at three positions during each rotation of the beam. <IMAGE>

Patent GB-2108817-A (GB)
Title: Animal feeding apparatus
Inventor: HORSWOOD SIDNEY
IPC: A01K5/02
Filed: 1982-10-28
Abstract: A feed hopper 20 is adapted to reciprocate lengthwise of an elongate feed trough 12. A feed dispenser 60 is supported in the trough 12, upon a wire grid 30 which serves as a track. Feed from the hopper 20 passes through the dispenser 60 into the trough 12. The lower portion 22 of the hopper 20 is received within the dispenser 60, and entrains the dispenser 60 for reciprocating movement lengthwise of the trough 12. However, there is no direct connection between the hopper 20 and dispenser 60, and the hopper is supported independently of the dispenser 60, to allow the latter to follow the grid 30. The lower portion 22 of the hopper 20 is shorter than the dispenser 60, so that there is some lost motion between the hopper 20 and the dispenser 60, each time the hopper 20 reverses its direction of motion. <IMAGE>

Title: Antenna apparatus
Inventor: NAGAOKA SINZI
IPC: H01Q1/12
Filed: 1983-01-14
Abstract: An antenna apparatus has a support device (11, 12) to be fixed to a given installing body (A), an antenna body (22) e.g. a parabolic reflector having a given directivity, and a ball joint (15) mechanically coupling the support device (11) to the antenna body (22). Two different positions (25a, 25b) of the antenna body (22) are coupled via a wire or rope (321) so that the direction of the antenna body (22) with respect to a given axis is changed by the push-pull movement of the rope (321). Similarly other pairs of positions connected by wires 322, 323, 324 provide orientation about other axes. Once the apparatus has been installed and the direction adjusted, the wires are fixed so that the reflector cannot move. Details of fixings, pulleys, ball joints and clamps are disclosed. The arrangement is useful for domestic reception of Super High Frequency signals from a geostationary satellite. <IMAGE>

Title: Method of supervising an instruction-transmitting system and circuit arrangement for carrying out the method
Inventor: ROHR GUSTAV
IPC: B60L3/12
Filed: 1983-11-14
Abstract: For the supervision of an instruction-transmitting system for electric signals, comprising a signal input device 1 and a receiver 2 which is connected to the signal input device by a line 4, 5, the signal input device is supplied with electric signals, which are different in kind, particularly in frequency, from the control signals which represent the instruction. The receiver is preceded by a comparator, which is supplied with signals of said different kind, particularly at said different frequency, and the transmission state of which is controlled at the frequency of the electric signals of said different kind in such a manner that, in dependence on the comparison of the signals of said different kind, a control signal will be transmitted or an error signal for disabling the receiver will be generated. The electric signals of the different kind are generated by an oscillator 7 which is connected to the signal input device and to a synchronous detector 12 disposed close to the receiver. <IMAGE>

Title: Cartridge type valve for liquid petroleum gas cylinders
Inventor: TOYNE CEDRIC CHRISTOPHER
IPC: F17C13/04
Filed: 1983-11-22
Abstract: A liquid petroleum gas cylinder valve, eg. the type used with clip on regulators, has a body (2), a main valve (1) in the form of a cartridge, and a pressure relief valve (3) also in the form of a cartridge. Built into the body is a stop-off valve. When the main valve becomes faulty by leakage etc. item (1) is removed and replaced with a new one. The same applies to the pressure relief valve. This is done while leaving the body in place in the cylinder. This serves two main purposes:- a) it is more economical to replace a part thereof than to replace the whole unit. b) While the main valve cartridge is removed the air entering or gas escaping is prevented by a stop-off valve. The pressure relief valve cannot be removed until the main valve is removed. <IMAGE>

Title: Filtration
Inventor: OSWALD BRIAN JAMES
IPC: B01D37/00
Filed: 1985-12-12
Abstract: To remove solids from a liquid such as sea water, the liquid is pumped into a membrane filter module, which may be of the cross-flow type, a pulsating flow being imposed on the liquid upstream of the filter by means of a rotating ball valve in series with a centrifugal pump, thereby reducing clogging of the filter membrane. The effect may be enhanced by providing the membrane with a grooved upstream surface, inducing local vortex mixing. Sea water so filtered may be deaerated and then pumped into oil-bearing rocks to displace the oil.   <IMAGE>
