Abstract: 1,147,940. Brackets. DOM HOLDINGS Ltd. 1 June, 1967 [29 Nov., 1966], No. 53446/66. Heading A4B. [Also in Division E2] A clip comprises a base member 1 by which the clip can be attached to the surface and a resilient clip member 4 slidable on the base member to be retained thereby, the clip member having a portion spaced from the base member so as to form an aperture in which an article such as a cable or earthing strip is retained and the clip having integral means for preventing accidental and sliding movement of the clip member after it has been assembled on the base member. In the construction shown the base member includes upstanding edge portions 3 so that the base member has a channel in which the article is received the channel being closed by the clip member. The clip member 4 has two downturned portions 6 the ends of which form a slanting groove 7 and this groove co-operates with extended portions 8 of the base member for the sliding interengagement. The upstanding portions 3 are each provided with a recess 10 in which a projection 11 carried by the clip member engages to prevent separation of the two members. In a modification the recesses are in the extended portion 8 and the projections which engages with them are suitably positioned on the clip member.

Abstract: 1446348 Food treatment C W WEST 4 Dec 1973 [15 Dec 1972] 56139/73 Heading A2D A food processing apparatus comprises a cooking chamber, a heat source for cooking a food product contained in said chamber, and a closed air treatment system which is independent of outside air temperature and humidity conditions and which includes means for withdrawing air from said chamber during the cooking of said food product, means for cooling the withdrawn air to a temperature below the dew point thereof to condense moisture therefrom and to thereby lower the humidity thereof, and means for recycling said cooled and conditioned air directly to said processing chamber for reheating therein. The cooling means preferably includes a shower tower having an air inlet, an air outlet, nozzle means arranged in the tower between the inlet and outlet, and a pump means for supplying water to the nozzle means. An apparatus of the above type is shown in the accompanying Figure. In operation, food is heated in chamber 10 and air carrying moisture from the food is passed along conduit 20 to conditioning tower 22. In this tower, the moisture-laden air is passed upwardly whilst sprays of water 25 pass downwardly thus removing moisture from the air. The conditioned air is then recycled to chamber 10, optionally via smoke generator 12. The flow of contaminated air from chamber 10 may be controlled by damper 21 or by preselected variations in the humidity of air within the chamber. The conditioning tower 22 is provided with water reservoir 30 and water discharge pipe 46. Fresh water is supplied to the reservoir 30 via pipe 36. This supply is thermostatically controlled by valve 34. The pump 42 may be coupled to wet bulb thermostat 43 so as to control the conditioning of contaminated air in tower 22 and thus control the moisture content of the air in processing chamber 10. The apparatus is particularly applicable to the treatment of meat or fish.

Abstract: 1474699 Colour separating prism assembly RANK ORGANISATION Ltd 11 Dec 1974 [11 Dec 1973] 57285/73 Heading G2J A three colour beam-splitting assembly, e.g. for colour television, comprises four prisms P 1 -P 4 , the arrangement being such that the air-gap G 1  between first and second prisms is bounded by spectrally non-selective surfaces, the second air-gap G 2  between second and third prisms is bounded by spectrally selective dichroic surface, and the third and fourth prisms are separated by a further spectrally selective dichroic coating. The angles and arrangement of the prisms and the selection of dichroic coatings is such that green light entering the assembly is selectively dichroically reflected at layer D 1  and is subsequently totally internally reflected at G 1  ; blue (or red) light is selectively dichroically reflected at D 2  and is subsequently totally internally reflected at G 2 , and red, or blue, light is transmitted straight through the whole assembly, the characterising feature being that the spectrally "central" colour of the three be the first to be separated. The above desiderata give rise to a series of mathematical inequalities with which the prism properties must conform. UK Specification 1401476 is mentioned.

Windscreen-washing apparatus for a vehicle is made up of a spray nozzle made of a resilient material with an outlet aperture in a mushroomlike head which is adapted for being secured in such a manner but forces tending to close the aperture are produced in the head, so that the aperture is closed when the apparatus is inoperative, but opens under the influence of the pressure of the washing liquid when the apparatus is operated. As shown the spray nozzle 4 of a windscreen washing installation is arranged in a hole 1 in the sheet-metal apron 2 in front of the windscreen 3. The nozzle 4, which is made of rubber or of a plastics material having rubber-like properties, has above the apron 2, a mushroom-like head 5, which is adjoined under the apron, by a shank 6. The arrangement is such that, when the nozzle is not installed, the outer edge 8 of the head 5 extends downwardly towards and overlaps the groove 7 (fig. 2 not shown). The shank 6 has a bore 9 which continues into the head 5; from the bore 9, a fine slit 10 leads out through the head 5 towards the screen 3. The slit 10 is maintained closed by forces produced in the head by edge 8, and opens when under pressure from the washing liquid.
