Abstract: 927,675. Self-propelled missiles. L. BOLKOW, [trading as BOLKOW - ENTWICKLUNGEN KOMM.-GES.]. April 17, 1961 [April 16, 1960], No. 13744/61. Class 9 (2). [Also in Group XXVI] A self-propelled missile has a detachable nozzle, the point of separation being at, or slightly in front of, that part of the nozzle having minimum cross-sectional area. At Fig. 3, part 13 of the nozzle is push-fitted on to part 12, which part is constituted by the rear of the missile body. During burning of the propellant charge internal pressure retains part 13, but on termination of burning it is forced off by external air pressure. Various embodiments are described including providing parts 12, 13 with cylindrical members, external to the throat of the nozzle, which engage with a tight push-fit, and welding or soldering around the joint of parts 12, 13, the welds melting during passage of the propellent gases. Also, the nozzle may be made as one unit and have an annular groove around the throat which causes separation after being heated. Additionally the groove may contain a ring of explosive which is ignited as the thrust terminates or a predetermined time afterwards. At Fig. 7, after detachment of part 42, spring plates 44 come together to close the end of the missile and improve its aerodynamic shape.

Abstract: 725,217. Moulding dough. HANSEN; F. F. May 20, 1953, No. 14206/53. Class 87 (2). A pressure or rolling board for a bread dough moulding machine comprises a fixed supporting structure, a movably mounted driven belt positioned below the structure, means to drive the belt to roll bread dough rolls under the structure, and a series of separately movable flat surfaced triangularly shaped rolling sections arranged in tandem and attached to the structure with yieldable compressions springs between the structure and each section, the surface of the rolling sections being spaced from the belt to form a pressure rolling surface for dough rolls carried thereunder by the belt. -After a lump of dough 10 has been sheeted by being passed between pairs of rollers 12, 14; 18, 20 and 24, 26 it is rolled up by the curling screens 28 and carried by a belt under the pressure board. The pressure board, Fig. 3, comprises a series of sections 38, 40, 42 designed to knead and elongate the roll and thereby drive out trapped air which would, cause holes to appear in the loaf when baked. The sections are triangular, of progressively increasing size, Fig. 2, and arranged so that their apices meet the centre of a rolled length of dough which is spread outwards as it is carried by the belt 32 beneath the sections, one roll of dough only falling at one time beneath them. The sections also increase in thickness, Fig. 3. Their dimensions vary according to the size of loaf to be made; the Specification mentions typical figures. The sections are resiliently mounted by springs 48 between them and a flat board 36. There may be springs on both sides of the sections, enabling them to move upwards and downwards with a rocking motion. The pressure on the dough is counteracted by a supporting board 49 below the belt 32. As an alternative to the spring mounting the sections 38, 40, 42 may be made of sponge rubber; otherwise they may be of wood, plastic material or hard rubber. A flexible stationary canvas belt 50 assists in controlling the movement of the dough through the apparatus. The belt 50 is endless, passing round rollers 52 and 54 at the ends of the board 46, and may be moved so that the portion of it which has been in contact with the dough is brought uppermost for cleaning; this movement being effected by a handle 56, Fig. 6, and the belt being locked in its stationary position by a latch 62 and stop wheel 60.

Abstract: 607,601. Radio navigation. WILLIAMS, F. C. June 7, 1945, No, 14453. Drawings to Specification. [Class 40 (vii)] In an aircraft guiding system, control potentials dependent upon the displacement of the aircraft from the predetermined track are modified in dependence upon the bank, rate of turn or change in angle of incidence of the aircraft in order to prevent an oscillatory approach to the correct track. The control potentials proportional to displacement may be derived from voltages proportional to angular deviation produced by an overlapping beam system and range information derived from a radar system, or from the signal strength in a simple overlapping beam system. Alternatively the control potentials may be derived directly in terms of distance from a track such as an orbiting track about a beacon. The modifying potentials may be obtained from suitable pick-up devices on bank or rate of turn indicators or from an horizon indicator in the case of a glide path system and before being fed to modify the displacement proportional potentials, are passed . through a resistancecapacity integrating circuit. Alternatively, the modifying potentials may be derived from a directional gyroscope, voltages related to the heading of the craft being applied to a resistancecapacity differentiating circuit before effecting the modification of the displacement potentials.
