Title: Lightweight heat-insulating refractory - comprising lithium aluminosilicate enamel on a silica fibre support
IPC: C04B35/63
Filed: 1973-06-05
Abstract: A low-density heat-insulating refractory material comprises (a) a support made by grinding down pure SiO2 fibres and then agglomerating and sintering them, coated with (b) a layer of Li aluminosilicate enamel, and separated therefrom by (c) an intermediate layer comprising a mixt. of pure SiO2 fibres and finely ground SiO2 grains. The refractory can be used as a furnace lining, as a heat shield, and esp. as a lightweight insulating material for aerospace applications, e.g. as an external lining for spacecraft or orbital engines. The refractory is very light (density ca. 0.15 g/cm3) and has a low thermal conductivity (e.g. 0.1 W. m-1. degree K-1 at 600 degrees C and 0.2 W.m-1, degree K-1 at 1200 degrees C). The intermediate layer prevents the enamel from diffusing into the support, thus avoiding surface deformation on heating. The refractory is highly resistant to thermal and mechanical shock and its surface is impermeable.

Title: Automatic control circuit for a lamp - uses a photo-cell to control a relay with two thyristors
IPC: H03K3/42
Filed: 1974-03-19
Abstract: In this control circuit a relay (7) causes a lamp (4) or some other load to be switched on or off depending upon the state of a photo-electric cell (11) which operates an electronic trip circuit (10) supplied by rectified mains voltage (12). When the trip circuit switches on, a thyristor in series (8) with the relay conducts and a relay contact (14) short-Circuits the thyristor and locks the relay on. Another relay contact (15) energises the load. When the trip switches off, a thyristor (9) across the relay conducts and short-circuits the relay which de-energises and switches off the load. Thus the relay is only pulsed during the switch moments and the circuit remains simple.

A visual display (159) is provided to show the recording-head position. Transmission of the codes is via a decoder, a store and thre monostable multi-vibrators generating the approved signalling waveforms. This system eliminates errors due to incorrect positioning of the drum.

Title: Opening of valves in paper or plastics bags - uses suction element gripping outer valve hose wall with side walls bent over
IPC: B65B43/26
Filed: 1974-12-23
Abstract: The opening of the valve hoses of valve bags made from paper or plastics is carried out by using a suction element gripping the outer valve hose wall. The bag side walls are bent around an edge extending next to the base of the valve hose and parallel to the long axis of the valve hose. At the same time the suction element exerts a pull in the plane of the bent over bag section on to the outer valve hose wall, which opens the valve hose. The suction element brings the valve hose into a position, in which the bending of the bag side walls takes place. After the opening process the suction element inserts the opened valve hose onto a filling socket of a filling machine.

Title: Electrical active or inactive power measurement - uses a pulse length pulse amplitude modulation multiplier
IPC: G01R21/00
Filed: 1976-03-17

Title: Temp compensated zener diode - avoids uneven current distribution by enclosing breakdown and emitting junctions with poor emitter
IPC: H01L29/866
Filed: 1976-03-19
Abstract: The temperature compensated zener diode has three regions of alternate conduction type forming an inner zener or avalanche breakdown junction and an emitting pn-junction. The inner breakdown junction (1) is arranged inside the semi-conductor chip (4) parallel over the whole of its length to an inner pn-junction (2) behaving as a relatively good emitter. Both the breakdown and the emitting junctions are encircled by a region (2') of poorer emitting properties than the emitter junction and of the same conductivity type. The good-emitter junction (2) has a higher breakdown voltage than the breakdown junction (1). The arrangement avoids uneven current distribution within the diode.
