Abstract: 1,274,848. Extruding foodstuffs. UNILEVER Ltd. 31 July, 1969 [5 Aug., 1968], No. 37343/68. Heading B5A. [Also in Division A2] Shaped portions of foodstuffs are prepared by passing the foodstuff while frozen through an extrusion nozzle having a contorted passageway and setting and sub-dividing the extrudate, the setting being a treatment to the extrudate such that its shape determined by the contorted passageway is retained after thawing. Preferred foodstuffs are fish, e.g. scampi, meat, e.g. sausage meat shaped to form curled skinless cocktail sausages, and potato mash. Other foodstuffs mentioned are vegetables and fruit. The setting treatment for fish may be by breading or batter coating the extrudate and partially frying, and for sausage meat and mashed potato may be by contacting the extrudate surface, by immersion or spraying, with hot fat or oil. Phosphate may be added to the fish before shaping; a number of suitable phosphates are listed. The extrusion temperature is preferably up to 5 C. below the freezing point of the foodstuff. As shown, the extrusion nozzle comprises a two-turn helical passageway 37 formed in a block of P.T.F.E. Three examples are given wherein the foodstuffs are respectively scampi, potato mash and sausage meat.

Abstract: 1,098,426. Aircraft instruments. SPERRY GYROSCOPE CO. Ltd. Aug. 28, 1966 [Sept. 3, 1965], No. 37646/65. Heading B7W. In an aircraft instrument as described in Specification 1,071,882 for use during take-off operations, the so-called "VR trigger" 41 is rendered ineffective by an electric switch that is connected thereto by a line 42 and is actuated by the undercarriage when the load thereon is removed due to the aircraft becoming airborne so that the pitch-director index 35 can function in response to the signal X, irrespective of the speed of the aircraft, immediately after the aircraft leaves the ground. A time-lag of e.g. 3 seconds, may be permitted before the signal produced by the switch renders the VR trigger ineffective so as to prevent premature operation of the index 35 when the aircraft is travelling across uneven ground before it becomes airborne. The switch may be replaced by other means for detecting unloading of the undercarriage. It is stated that said switch may be connected to the rate demand limiter in a circuit that is in parallel with the VR trigger so that failure of either the airspeed sensor 38 or the VR trigger does not prevent application of the signal # to the index 35 when the aircraft leaves the ground.

Dec. 13, 1929, No. 38296. Convention date, Dec. 24, 1928. [Class 39 (ii).] In structures of the kind wherein glass and metal elements are hermetically sealed together, the seal between the members consists of a metallic skirt adapted to be united to the glass envelope and formed integrally with the conducting-material. The example shows an X-ray tube wherein an anode 2, Fig. 1, of the usual form located within an evacuated envelope 1 terminates in a shank which is preferably consituted by two cylindrical portions 3, 4 butt-welded together or secured end to end in any other manner. The anode shank 4 is formed with an integral skirt or flange 11 which extends radially therefrom and is tapered to a fine edge to engage within a glass beading 12 at the end of a re-entrant portion 6 of the cylindrical tube 5, the skirt member 11 being sealed within the glass beading in known manner. The skirt member 11 is formed preferably by an extrusion process, and preferably without heating, prior to the welding together of the portions 3, 4 of the shank, the portion 4 being located between a pair of split dies 13, Fig. 2, and subjected to a relatively high pressure longitudinally, thereby forming a protuberance which, by providing one of the dies 13 with a depression 14 is compressed until it fills the depression and assumes the shape thereof when the ends of the dies are in contact. Subsequently the shank portion 4 is held in a lathe and the skirt is spun or bent until it is of the shape shown in Fig. 1. The shank is preferably of a relatively soft ductile material such as copper which enables the extrusion on forming of the skirt to be effected without heating. Alternatively the skirt may be formed by turning down in a lathe a piece of material of the requisite diameter.
