Title: Improvements in or relating to aerial and associated feeder systems
Filed: 1937-10-28
Abstract: 504,733. Aerials; directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., WELLS, N., and LADNER, A. W. Oct. 28, 1937, No. 29529. [Class 40 (v)] Two or more spaced aerials 1, 2, Fig. 1, for directive working, are energized by a central feeder 3 with branched horizontal limbs 5a, 5b connected to the upper ends of each of the main aerials which may take the form of masts, as shown, and be directly earthed. The impedance of the vertical limb of the feeder is made higher than that of the horizontal limbs, so that the current' through the former is cut down and any detrimental effect on the directional field reduced. Radiation from the horizontal limbs is mutually cancelled owing to their proximity. The main aerials may be a quarter, three-eighths, or threesixteenths of a wavelength high, and spaced apart by either a half or quarter wavelength. The typical current-distribution is, as shown, for instance, in Fig. 3, where reactances 6 are used to secure the required phase-relations. The horizontal limbs of the feeder may be bent-over to suppress radiation, Fig. 5, (not shown). Fig. 6 shows an arrangement of three main aerials 1a, 1b, 1c with horizontal top-feeders 5d, 5e, 5f giving a non-directional radiation-field. The vertical feeder may also be arranged so that, in conjunction with the main radiators, the proportion of high-angle radiation is cut down. The phasing and tuning of the system is controlled by a single tuning circuit at the base of the vertical feeder, and by the disposition of the horizontal feeder branches.

Abstract: 400,770. Turning-gear. SCINTILLA AKT.-GES., Solothurn, Switzerland. Oct. 22, 1932, No. 29541. Convention date, Oct. 24, 1931. [Class 7 (v).] An electric starting motor is provided with a pinion a engaging keyways on a shaft c, which is driven from the motor through an overrunning clutch d and is displaced axially, to engage the pinion with the engine flywheel b, by a lever g and a sliding member e engaging a grooved collar f on the shaft c. A spring m between the pinion and the collar f is compressed if the teeth of the pinion clash with those of the flywheel ; the motor is then switched on by an arm h of the lever g and when the rotation of the shaft c has brought the teeth into register, the pinion is moved into mesh with the flywheel by the spring m, which displaces only the small mass of the pinion. The meshing movement is cushioned by a spring k. In modifications, (1) meshing is effected by movement of the shaft c and pinion a towards the motor ; (2) the shaft c extend axially through the armature, the lever g and pinion a being at opposite ends of the armature and meshing being effected by movement either away from or towards the motor.

Abstract: 868,148. Measuring electrically. CLEVITE CORPORATION. Sept. 16, 1958 [Sept. 16, 1957], No. 29601/58. Class 40 (1). [Also in Groups XXXIX and XL (b)] The transducing element of an instrument for measuring rate of turn (angular acceleration) by electrical means comprises a piezo-electric bimorph. The bimorph consists of two rectangular plates 10, 12, one responsive in a face shear mode and the other in an axial extensional mode. They are provided with separate pairs of electrodes on their major faces and are cemented together face to face in such a manner that one plate responds to flexure of the assembly and the other to torsion (see Group XL (b)). Thus, if the assembly is rigidly mounted at one end upon a base 48 and the base is rotated about the axis Z, any change in angular velocity will result in twisting of the element and an output proportional to the degree of twist will be obtained from the face-shear plate 12. In the embodiment shown, the sensitivity is increased by applying an A.C. signal to the expanding element 10 in such a manner that the assembly vibrates in a bending mode at its resonant frequency. The output measured by the meter 52 will then be an alternating potential.

Abstract: 1,012,755. Winches. ATLAS-WERKE A.G. Aug. 2, 1962 [Sept. 7, 1961; April 16, 1962], No. 29769/62. Heading B8B. In a constant tension device for a steam or hydraulically driven winch the steam or fluid supply for the motor 45, Fig. 3, is controlled by a normally manually operated control valve 33, the movements of which are influenced by the hawser tension. In the example, a shaft 2 carrying the winch drum is driven from a steam engine 45 through spur gears 46, 1, the gear 1 being resiliently coupled to a plate 4 on the shaft 2 through spring links 3 which permit limited relative rotation between the gear 1 and shaft 2 to an extent proportional to the shaft torsion and thereby indirectly proportional to the hawser tension. The relative rotation is transmitted through a linkage system (not shown) to cause axial displacement of a sleeve 15 on the shaft 2 and from which movement is transmitted to the slide valve 33 through a linkage 20, 23. Manual adjustment for presetting the required tension setting is obtained through a threaded coupling 24, 25 which permits relative adjustment between the valve 33 and the linkage system. The winch has a further valve 34 for cutting off the steam supply at predetermined maximum and minimum lengths of hawser. The valve 34 is moved through rotation of a screw-thread device 37 driven from the shaft 2 through bevel gears 36. Manual adjusters 38a, 38b provide for setting both the maximum and minimum lengths by separate adjustment of the two parts 34a, 34b of the slide valve.

[Class 8 (i)] [See also Groups XXXIV and XXIX] In hydro-pneumatic apparatus for operating brakes and for other purposes comprising a charge reservoir containing liquid under air pressure and a pump which delivers liquid from a discharge reservoir to the charge reservoir the pump has a clearance space which is greater than that necessary for delivering air to the charge reservoir at the required working pressure so that the pump after having delivered all the oil permanently contains air and liquid in the clearance space. Heating of the pump is thus avoided. The system shown in Fig. 2 comprises a charge reservoir c which supplies through a cock r a hydraulic brake cylinder e on the tractor vehicle of a train, and also through a cock r<1> a pneumatic control pipe z for controlling brake cylinders e<1> on trailer vehicles. In initially charging the system, oil placed in the discharge reservoir d is delivered by the pump p to the reservoir c thus raising the pressure in the reservoir c and at each stroke of the pump after all the oil has been delivered from the reservoir d a certain amount of the oil that remains in the clearance space t of the pump is carried over with the air that is then delivered to the reservoir c so that the effective volume of the space increases as the pressure in the reservoir rises until a condition of equilibrium is reached at which the pump runs idly, the valves a, b ceasing to operate. By operating the cock r the cylinder e may first be charged from the reservoir c and then be discharged into the reservoir d, the liquid being then returned by the pump to the reservoir c.
