Title: Method of producing hops pellets
IPC: C12C3/06
Filed: 1978-07-19
Abstract: The invention relates to a method of producing hops pellets with a reduced water content from crude hops with a higher water content of e.g. 13%. The crude hops, possibly comminuted, are pelleted before any drying in a dryer occurs. The pelletisation causes the hops to become heated, usually to around 50 DEG C, and results in an initial drying. Thereafter drying in a dryer may be carried out by passing an air stream of up to 50 DEG C over the pellets. Fig. 2 depicts apparatus in which the pelleted hops are dried by a current 14 of air heated to the required temperature in heat ex- changer 15 and are subsequently cooled by cooling air 10, during passage on belt conveyors 3, 4, respectively. <IMAGE>

Title: Utilisation of wave motion
IPC: F03B13/12
Filed: 1978-12-01
Abstract: A power unit comprises a resonator having a mouth located in the sea and containing a body of water and an air cushion above the body of water. This resonator can have a neck defining a relatively small flow area compared with the surface area of the body of water immediately below the cushion. The air cushion is controlled by pressure sensor 35.1 and reversible compressor 35.3 to cause the water to resonate in response to pressure fluctuations resulting from wave motions in the sea, thereby developing fluctuations of increased pressure. The unit is constructed so that the increased pressure fluctuations create a fluid flow through an outlet 40 and tank 38 to drive a turbine 48 driving an alternator 50. Again, the resonator is used to drive a ship, the flow through outlet 40 being fed to a jet nozzle, or reversible vanes being provided at the mouth 32 of an otherwise closed resonator. <IMAGE>

Patent GB-2028375-A (GB)
Title: Carbothermic Production of Aluminium
IPC: C22B21/02
Filed: 1979-08-15
Abstract: In the production of aluminium by the carbothermic reduction of alumina in a two-stage process, the molten slag containing Al2O3 and Al4C3 in the first, lower temperature stage is passed to the second, high temperature stage where the reaction Al4C3(in solution)+Al2O3->6Al+3CO- (1> occurs. The resulting carbon monoxide gas which contains aluminium metal fume and Al2O is passed into the molten slag of the low temperature stage, whereupon it gives up its sensible heat to the slag and, since the reaction (1) above is reversible at the lower temperature of the slag, a back reaction occurs, thus effecting a recovery of the aluminium. <IMAGE>

Patent GB-2040804-A (GB)
Title: Improved heat-sealing irradiated film
IPC: B29C48/00
Filed: 1979-12-21
Abstract: The invention relates to multi- layer polymeric structure, especially film, which can be produced by irradiation crosslinking of the polymer of a first layer without damage to the heat- sealability of a heat-sealable second layer. By including in the first layer a chemical component which when blended with a polymer in the melt form produces a material which crosslinks to a greater extent under irradiation than does the same polymer alone, it is possible to reduce the dosage of irradiation required for satisfactory cross-linking and thereby reduce or prevent damage to heat-sealing characteristics of the second layer. The laminate is useful for orientation to produce heat-shrink packaging material.

The device 11 is fixed in position in the tank by ultrasonic welding, friction welding or adhesive. <IMAGE>
Patent GB-2059192-A (GB)
Title: Controlled regenerative D-C power supply
IPC: H02M7/162
Filed: 1980-09-02
Abstract: A-C energy, from an a-c power system, is converted by a phase- controlled SCR rectifier bridge, which is followed by a series-connected filter choke (21) and a shunt-connected filter capacitor (29), to d-c power for delivery via a d-c bus to a load, such as an inverter (24) and an a-c induction motor (32) driven by the inverter. When there is a decrease in load demand, for example when the motor speed is to be reduced, fast speed control is obtained by regenerating power back into the a-c power system from the load. Power flow through the d-c power supply is reversed by means of a switching network (22,25,41,42), interposed between the filter choke (21) and capacitor (29), having a pair of reverse SCR's for cross-coupling the positive and negative lines of the d-c bus. When the reverse SCR's are fired into conduction, the connections between the filter capacitor and the bridge's output terminals are effectively reversed, thereby facilitating power flow from the load to the a-c power system. <IMAGE>

Patent GB-2089136-A (GB)
Title: Electric motor
IPC: H02K29/06
Filed: 1980-12-02
Abstract: A rotor 10 has projections 11 which confront similar projections 17 on poles 15 of a stator 14; and in any position of the rotor 10, the projections 17 on only one opposed pair of the poles 15 registered with the projections 11. Field windings 16 on the poles 15, and an armature winding 12 on the rotor 10, are energisable to provide either continuous or incremental operation. For incremental operation, winding 12 is not energised but direct current is passed through the windings 16 successively from one pole pair to the next, the speed of rotation of the rotor 10 being determined by the frequency with which the current is switched from one pair of windings to the next. For continuous operation, all of the windings 16 are energised together and a direct current is passed through the armature winding via slip rings (19), the current flow direction through each pair of windings 16 being reversed as a control axis (N) of the armature winding passes the centre line of the respective pole pair. <IMAGE>

Title: Improvements in the manufacture of confectionery
IPC: B29C33/46
Filed: 1981-06-03
Abstract: The invention relates to confectionery moulding apparatus through which moulds 7, each containing at least one mould cavity 13 having minute holes 15 in its base, are traversed successively by a conveyor, not shown. After filling with confectionery and subsequently cooling, the moulds pass in inverted relation beneath a demoulding unit, not shown, which blows air through the holes in the bases of the mould cavities to eject the confectionery from the cavities. To reduce the force required for demoulding, each mould has a backing plate 14 spaced from the perforated base of the mould cavity or each mould cavity to define an air chamber 8 and the demoulding unit includes an air pipe 9 which is brought into sealing engagement with a hole 11 in the backing plate of each mould to deliver air into the chamber and so effect demoulding. <IMAGE>
Patent GB-2082784-A (GB)
Title: Apparatus for Testing Electric Insulating Material
IPC: G01R27/26
Filed: 1981-07-15
Abstract: An apparatus for analysing dielectric loss caused by ionization or discharges in gas- or vapour-filled voids of an electric insulating material specimen 28 is disclosed in the form of a bridge circuit having arms 6, 8, 10 and 12. The X plates of a CRT 38 are energised by tapping points on arms 6 and 8 which are made up of fixed capacitors. The Y plates of the CRT are energised by the potential between terminals 20 and 30. With a low AC voltage applied across the bridge terminals 18 and 26, resistor 32 and capacitor 34 are adjusted to give a straight line trace. As the AC voltage across the bridge is increased, eventually ionization or discharge takes place in the voids in the specimen 28, causing abrupt changes in its capacitance. The straight line trace therefore expands into a generally parallelogram-type shape. Each abrupt change in capacitance produces a corresponding voltage change which is converted into a voltage pulse by the ringing effect of an inductor 36 and the pulses are visible on the sloping sides of the parallelogram. The pulses therefore enable the point of inception of the discharges to be determined, even in the presence of other non-linear effects which might distort the shape of the trace. <IMAGE>
