Title: Cylindrical array antenna
IPC: H01Q3/24
Filed: 1971-06-30
Abstract: 1323384 Aerials HAZELTINE CORP 30 June 1971 [27 Nov 1970] 30552/71 Heading H4A In an aerial array radiating elements are arranged along a path, which may be circular, and possibly shaped to fit the fuselage of an aircraft. The elements may be dipoles, or vertically stacked dipole arrays. A set of signals having a selected phase distribution is developed, and is applied to a corresponding group of aerial elements in a predetermined order. The beam radiated by the array is steered in coarse increments by selecting different groups of elements along the path, the predetermined order of illumination being maintained, and is steered in fine increments by selecting different phase distributions for the signals. As described, 32 consecutive elements of a circular array 11, Fig. 3, of 128 dipoles a 1  to a 128  are simultaneously energized by a signal applied to the sum port of a hybrid 16. A divider network 18 provides 32 signals from the two outputs of the hybrid 16. These signals may be symmetrically tapered in amplitude distribution and have fixed phase differences (obtained by inserting lengths of transmission line) to compensate for the curvature of the array. The outputs of the divider network 18 are coupled to the inputs of a coupling means 14 through phase shifters 19, which are of the electronically controlled digital type, giving eight selectable values of linear phase distribution across the group of radiating elements, for fine steering. The coupling means 14 comprises a switching matrix of 80 individually selectable double pole change-over switches (Fig. 3a), which enables any input signal to be connected to any one of its output terminals. The said output terminals are each connected to the input of one of 32 single pole four throw switches of a bank 22. Each of said switches is coupled to a respective set of four radiating elements which are spaced 90 degrees apart, and by operating appropriate switches any group of 32 consecutive radiating elements may be selected. A control means comprising logic circuitry is also described (Fig. 4, not shown).

Title: Improvements in or relating to trip mechanism for disc-reproducing apparatus
IPC: G11B17/02
Filed: 1954-10-25
Abstract: 751,207. Automatic gramophones. STAAR, M. J. H. Oct. 25, 1954 [Aug. 2, 1954], No. 30677/54. Class 40(2) A trip mechanism for the control means in the automatic control of a gramophone, such as for stopping the machine or effecting the traverse of a pick-up arm 2, as to prevent the rapid movement of an actuating member at the end of a record, whereby the control means is actuated. In the embodiments described the control means comprise switch blades 10 11. During the traverse of a pick-up arm 2 as shown in the underneath view in Fig. 1, a follower arm 4 is moved therewith. The arm 4 carries a cylinder 5 containing a viscous fluid or grease 10 surrounding a member 6 whose rapid movement within the cylinder 5 is resisted by the said fluid or grease. The member 6 has an arm 8 which comes into contact with a roller 15 on a blade 14 coupled to switch blade 11 by an over-centre acting loop spring 13. During normal inward traverse of the pick-up arm the member 6 slips within the cylinder 5, and the switch blades 10, 11 remain in contact, but when the stylus runs into the run-off groove of the record, the resistance of the viscous fluid causes the blade 14 to be pushed past the overcentre position to break the contact between blades 10, 11. When the pick-up is returned to the outer position a member 17 on the arm 4 returns the blade 14 to the normal position, while a pin 18 on the baseboard 1 returns the arm 8 to its initial position with respect to cylinder 5. In other embodiments described, the cylindrical surfaces acted upon by the viscous fluid are replaced by flat surfaces.

Abstract: 1,121,236. Knitting-machines. R. STEIGER. 12 July, 1966 [12 July, 1965], No. 31224/66. Heading D1C. A flat bed, or parallel machine includes a jacquard, controlling the position of cams e.g. 6 in the lock, including two series of feelers 24a, b controlling the position of the cams as the carriage moves away from and towards the jacquard, the latter control becoming effective only when the cams are remote from the jacquard. The cams are normally spring urged to the retracted position shown and are controlled by a cam slide a-c, having projecting arms 23d, g, engaging cam stud 6a. The cam is projected by moving the slide relative to the carriage so that cam c engages the stub. The cam may be retracted by lifting slide 37b by ensuring that the feeler 24b engages a perforation in a card 9a. At the far end of the traverse the cam is projected as the arm 23g strikes a fixed stop, unless a selection has been made previously to ensure that the cam remains retracted. Thus if at the end of the previous traverse slide 37a is raised by a feeler, and engages arm 39b of slide 36 the carriage continues so that arm 39a is projected and locked, automatically, to the cam slide. As the cam 39a strikes the fixed stop at the far end of the traverse, the carriage continues its traverse and moves the cam stub into notch b and thus retracts the cam.

Abstract: 460,466. Vapour-engine power plant. ZEHNLE, P., and KOECHLIN, A. Nov. 12, 1935, No. 31330. Convention date, Nov. 12, 1934. [Class 122 (iii)] [Also in Group XIII] Comprises a vapourengine plant using butane or like hydrocarbon in which the pressure of the vapour at condensation temperature is near or above atmospheric pressure and which is led in a closed cycle from a generator through a superheater and an engine to a condenser worked without the use of a vacuum pump. In the plant shown, steam is raised in the generator 1, superheated in the apparatus 2 and expanded in a turbine 3<a>. Part of the heat is used for industrial purposes, and part goes to the condenser or exchanger 6, the condensate being returned to the generator. The heat of condensation is used to vaporize and superheat butane in a secondary circuit. Heat may also be applied to the exchanger so that it functions as a superheater. The butane vapour which is generated at or above its critical temperature and critical pressure (140‹ C. and 40 atmospheres) is expanded in a turbine 3b and passes to a condenser 10. It is condensed at a temperature of about 25‹ C. under a pressure of 2À9 atmospheres. The absence of a vacuum eliminates the necessity of an air pump. The condensate is pumped back to the exchanger and may be heated in a reheater 13 by hot water from an economizer 14 associated with the generator 1. The Specification as open to inspection under Sect. 91 describes also the use of fluorcarbons, propane, and pentane. The use of heavy hydrocarbons such as fluorcarbons, butane, propane and pentane in a reversed cycle constituting a refrigerating-plant is also described. This refrigerating-plant constitutes the subject-matter of Specification 31331 /35. This subject-matter does not appear in the Specification as accepted.
