Title: Steering of missiles
Inventor: DUNN ALBERT JOHN
IPC: G05D1/12
Filed: 1982-02-10
Abstract: A beam-riding missile (10) has a freely rotating control portion (11) forming its nose and carrying a pair of fixed ailerons (13) and a pair of fixed elevators (14). Detecting means (not shown) gather information indicative of the location of the missile in the beam and steering logic circuitry (not shown) provides signals to a clutch (18) which interfers with the free rotation of the nose in such a way that the elevators are effective to maintain the chosen flight path. The clutch can be electromagnetic, piezo-electric or function on the Johnson-Raebeck effect. The combination of fixed control surfaces and steering by a single actuator leads to the possibility of useful reductions in the size, weight and complexity of the missile.

Patent GB-2130326-A (GB)
Title: Fastening insert
Inventor: NIVET ANDRE
IPC: F16B37/12
Filed: 1982-11-10
Abstract: A fastening insert for use in fixing a member by means of a bolt to a support 12 made of a fragile plastics material which is subject to deterioration as the insert is fitted into it, comprises an internally screw threaded cylindrical sleeve 2 having an external self-tapping screw thread 5. The screw thread 5 has a very acute angle between its flanks and a pitch which is substantially greater than its radial height. The thread thus cuts a narrow furrow 13 in the wall 14 of the hole 10 in the support 12 which avoids damage to the support. The sleeve is further provided with a helical rib 7 (or a series of protrusions) between the turns of the thread 5. The rib 7 does not cut into the wall 14, but holds the insert centred in the hole 10 as it is screwed in. Further there is a substantial clearance 15 between the sleeve 2 and the wall 14 to avoid any tendency for the insert to split the support as it is screwed in. <IMAGE>

Title: Hollow glass shell microcarrier for growth of cell cultures, and method of shell manufacture
Inventor: DOWNS RAYMOND LEROY
IPC: C03C11/00
Filed: 1982-12-20
Abstract: A hollow silicate glass microsphere of density >1 gm/cc., adapted for use as a microcarrier in anchorage-dependent cell cultures, and a process for manufacturing such microspheres. The process of manufacture features a method of tailoring the density of the microspheres to the density of the culture medium by first manufacturing the shells over-dense and then immersing the over-dense shells in an etching solution having the density of the culture medium. As the shells become buoyant, they are removed from the solution.

Title: Distributor and safety valve assembly for washing machines
Inventor: FORNASARI PAOLO
IPC: D06F39/02
Filed: 1983-02-25
Abstract: A solenoid inlet valve 8 is connected to a manifold 6 by way of an inlet port 19 controlled by a valve 17 actuated by expansion of wax 13 when heated by a heating element 14 connected in parallel with the main inlet valve 8. Both inlet valves are connected to the pressure switch 21 of the washing machine so that if this switch remains closed or the main inlet valve 8 remains open for any reason, water inflow is cut off by the valve 17 which closes with a delay due to the thermal inertia of its operating mechanism. The manifold has multiple outlets 10 leading to respective washing additive reservoirs or to the washing receptacle and controlled by further wax-operated valves 17a. The embodiment of Figs. 3, 4 has no single electrothermal valve able to stop all inlet of water. <IMAGE>

Title: Antenna arrangement
Inventor: PRICE DAVID JOHN
IPC: H01Q19/10
Filed: 1983-03-05
Abstract: A receiving and/or transmitting antenna arrangement has a dielectric lens (20), a reflector (30) at a surface of the lens and a planar, circular array (10) of antenna elements. The lens and reflector have rotational symmetry about an axis CC centred on, and normal to, the array to form a folded path for radiation. In fig. 1b the lens is generally annular, and in the alternative embodiment of fig. 8 it is generally conical. The lens and reflector create a reception and/or transmission response characteristic for the arrangement; each component in the characteristic is angularly distributed around, and similarly inclined to the axis. The antenna arrangement finds application in a fuse. In this context each element in the array may be used in conjunction with an adjustable range gate.

Title: Gas-fired appliances
Inventor: BARNES HUGH VERNON
IPC: F23N5/24
Filed: 1983-06-30
Abstract: A gas appliance including a flue break (11) with an opening (17) includes a thermostatically operated gas valve (6) for controlling gas flow to the burner (4) of the appliance. The thermally responsive element (8) of the thermostatic control is so positioned adjacent the flue break opening (17) that, under normal conditions, it will respond to the flow of ambient air entering the opening (17) and, under down draught conditions to the flow of combustion products and air leaving the opening (17). In the one case, the flow of gas is controlled according to ambient air temperature and in the other the valve acts to reduce gas flow to the burner (4) to a safe by-pass level. <IMAGE>

Title: Grinding workpieces on internal grinding machine
Inventor: FAHL HANS-JOACHIM
IPC: B24B51/00
Filed: 1983-08-09
Abstract: In a method for the optimisation of a grinding process for workpieces with large and considerably varying dimensions, made of materials which are difficult to machine, with extremely long bores and very high quality requirements, the initial conditions are made identical for all workpieces in the grinding process before the finishing stage and simultaneously the dressing speed is optimized in accordance with the specific conditions for the roughing and finishing. The roughing cycle is divided, working backwards from its end point, into predetermined uniform path intervals the end point of each of which is the starting point of a dressing process, and the grinding element is dressed at a high dressing speed for the dressing processes during the roughing cycle and at a low dressing speed for a dressing process relating to the finishing stage. <IMAGE>

Patent GB-2154103-A (GB)
Title: Data transmission system
Inventor: BAKER HENRY LOUIS
IPC: H04H20/76
Filed: 1984-02-07
Abstract: For transmitting data signals over a wired broadcasting system from a head end to individual subscriber terminals, synchronised sinusoidal and square wave power signals are generated at the head end. A transmission gate network is controlled by the data signals to connect one or other of the sinusoidal and square wave power signals to the wired system connecting the head end to the subscriber terminals in accordance with the data signals. A low pass filter provided in each subscriber terminal derives a sinusoidal power signal from the distributed signal for powering the terminal, and the output of the low pass filter is compared with the distributed signal to detect the data signal.
