Title: Improvements in or relating to microwave heating
Inventor: MEREDITH ROGER JOHN
IPC: H05B6/78
Filed: 1967-11-09
Abstract: 1,211,024. Microwave heating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 10 Feb., 1969 [9 Nov., 1967], No. 51099/67. Heading H5H. Apparatus for heating sheet material or discrete objects or particulate material using microwave energy comprises an applicator 3 adapted to propagate the energy as a slow wave only in a direction parallel to the direction of movement AA of the material 2 through a heating zone. A loss-free conveyer belt 1 of polypropylene conveys the material 2 through two halves 3a, 3b, of the applicator or, alternatively, a stainless steel belt 1<SP>1</SP>, Fig. 5 (not shown), carries material beneath an applicator 3<SP>1</SP> of similar structure to part 3a. Applicator part 3a has a plurality of channels A-F, each #/4 deep, with horizontal coupling slots S1-S4 therebetween and vertical slots V1-V3 to prevent propagation of energy transverse to the direction of material movement, the slots V1- V3 being 3#/8 apart. Energy is coupled from the waveguide W into channel A through slots L1-L4. Channels X, X<SP>1</SP>, prevent leakage from channels A, A<SP>1</SP>, to the outside of applicator 3 by acting as quarter wavelength chokes. In an alternative, the applicator is fed at the centre to propagate slow waves in opposite directions.

Title: Method and apparatus for chilling articles, especially food items
IPC: A23L3/375
Filed: 1966-12-20
Abstract: 1,177,354. Freezing foodstuffs. THERMICE CORP. 20 Dec., 1966 [29 Dec., 1965], No. 57038/66. Addition to 1,110,126. Heading F4H. Food articles are chilled by passage through a tumbler in a bed of powdered solid carbon dioxide produced by shaving a solid block. As illustrated, four rotating tumblers 100 are arranged in parallel and are fed with articles via conveyers 105 from a common input conveyer 101, adjustable scoops 111 being provided to proportion the input between the tumblers. Each tumbler is provided with a station for blocks of solid carbon dioxide in which the undersurface of a block 168 is shaved by a rotating scraper and the resultant powder passes down a shoot 128 into the tumbler. Chilled articles are removed from the downstream ends of the tumblers by an output conveyer 112. Solid carbon dioxide at the downstream ends of the tumblers falls through a perforated screen 142 into an annular chamber including lifting baffles from which, after lifting through 180 degrees, the carbon dioxide again falls through the screen 142 to be returned by a conveyer 146 to the input end of the tumbler. Gaseous carbon dioxide is removed from the downstream ends of the tumblers via boxes 222 by blowers 153 which exhaust it to the outer atmosphere. The capacity of the blowers 153 exceeds the amount of gaseous carbon dioxide generated in the tumblers and make up air is admitted through ducts 229. The tumblers are polygonal in cross-section and stationary scrapers 149 are provided. Solid blocks of carbon dioxide are carried up conveyers 116 and placed in position on the scrapers by rams 122. Plates 177 then press the blocks on to the scrapers. Pistons and cylinders 125 which act to move the plates 177 are adjustable to vary the rate at which the carbon dioxide is shaved. Control means are provided to automatically feed the blocks and to operate the shaving mechanism.

Title: Windscreen wiper blades
IPC: B60S1/38
Filed: 1973-12-10
Abstract: 1429820 Windscreen wipers TRICO-FOLBERTH Ltd 9 Dec 1974 [10 Dec 1973] 57088/73 Heading A4F A windscreen wiper blade comprises a body 12, 14 of rubber or rubber-like material integrally moulded around a single resilient strip 20 e.g. of metal, there being notches 38 spaced along the length of the blade which extend into the body 15 expose, or come close towards exposing, the strip 20. The notches 38 extend wholly or partly across the upper, lower, and side faces of the head portion 14 of the blade and some may meet at an edge of the blade and some may meet at an edge of the portion 14 to form L-shaped slots. The air turbulence resulting from the presence of the notches 38 lessens the tendency of the wiper blade to be lifted from the windscreen by the wind. The blade is connected to a harness 22 by claws 24, and to obtain a substantially uniform wiping pressure throughout the length of the blade, the width X of the blade portion 12 is progressively decreased from a minimum at the claws 24 to a maximum midway between the claws 24 thereby varying the permitted tilting of the portion 12 and rendering the torsional deflection of the strip 20 substantially uniform. Recesses 32 in the portion 12  prevent the claws 14 from interfering with the tilting of the blade portion 12. At least one of the claws 24 is latched between ramps 34 at the side, and also if desired on the top, of the blade portion 14. The blade may be formed by injection or compression moulding.

Title: Preparation of potassium
IPC: C22B26/10
Filed: 1966-12-22
Abstract: Potassium is produced by reducing potassium hydroxide, potassium aluminate or potassium silicate in the solid state with silicon in the presence of lime in a quantity sufficient to neutralise the silica formed in the reaction.  The reaction is preferably carried out at a temperature of at least 1,000 DEG C. and in an atmosphere of inert gas such as argon, helium or nitrogen. Silica may be added to the starting materials in which case the amount of lime is suitably increased. If the starting materials contain water, e.g. through hydration, the amount of silicon is increased to compensate.

The starter motor 9 for the internal-combustion engine of a vehicle is provided with main and subsidiary batteries 1, 2 and a control circuit arranged so that if the main battery 1 is unable to start the engine, the battery 2 can be parallel-connected therewith to provide the necessary reinforcement. The battery 1 is of the high capacity, low maximum current type, e.g. lead-acid, while the battery 2 is of the low capacity, high maximum current type, e.g. cadmium-nickel with thin sintered plates. To start the engine, a switch 19 is closed to close relay contact 11 and connect battery 1 to the starter motor 9. Should failure to start occur, e.g. due to a flat battery and/or a low ambient temperature, a triple-contact switch 16 is closed to close relay contacts 6, 11 and connect batteries 1, 2 in parallel and to the motor 9. After starting and opening of the switch 16, the batteries 1, 2 are charged by the vehicle's charging system either directly as for the battery 1 or through a circuit comprising a resistor 24, semi-conductor diode 25 and fuse 26 as for the battery 2. The battery 1 is connected to the other electrical loads of the vehicle via connection 14. The considerations affecting the choice of the batteries 1, 2 are discussed and typical performance characteristics are given for the various starting conditions described, Figs. 2 and 3 (not shown).
