Abstract: 627,103. Air-space cables. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd., DEAN, J. N., and SMITH, E. W. March 20, 1947, No. 7744. [Class 36] An air space coaxial cable, in which the air space is surrounded by a sheath of dielectric material, has positioned within the inner conductor a material having moisture-absorbing properties superior to those of the dielectric material, so as to delay any increase of humidity within the air space and consequent deterioration, of the electrical characteristics. In the case of a cable having a central conductor, as described in Specification 623,748, the absorbent material may form the central core, may be wrapped around the central core, or may be applied as a backing to the metallic tapes forming the inner conductor. Paper is a suitable material to use for the purpose. Additional protection may be given by providing the cable with a water excluding layer, such as metallic tapes applied helically over the outer sheath of the cable, and secured with an adhesive such as bitumen. An additional absorbent layer may be applied between different layers of the outer sheath of the cable.

Abstract: 638,155. Gramophones. McSORLEY, D. J., and ROBINS, J. T. March 21, 1947, No. 7843. [Class 40 (ii)] [Also in Group XXXIX] The turntable of a spring-driven gramophone is raised into engagement with a supported pick-up by a vertical movement of the turntable spindle. As shown, a turntable spindle 18 has a threaded upper portion 22 engaging a fixed screwed boss, the spindle being driven from a spring-motor shaft 17 by a pin-and-slot connection 21, 20. On releasing a starting latch 32 the turntable moves upwards by screw action until the spindle thread becomes disengaged from the screwed boss, when the motor shaft displaces slightly, relative to the spindle, so that the drive pin 21 engages a recess 26 and supports the spindle. During the upward movement of the turntable a needle 15 fitted to a pick-up 5 engages a gramophone record 24, further vertical movement of the turntable raising the pick-up clear of a support 14, thereby enabling the pick-up and record to co-operate in the usual manner. The device is used in conjunction with a burglar alarm for transmitting recorded messages over an automatic telephone system (see Group XXXIX).

Abstract: 741,953. Reinforced concrete. PRELOAD CO., Inc. June 23, 1954 [March 23, 1953], No. 7915/53. Class 20(4). [Also in Group XXVIII] In a method of applying longitudinal and circumferential prestress to concrete pipes and beams a number of circumferentially spaced rods or wires 6 of high-tensile steel are disposed longitudinal of the pipe 1 and the ends of the rods pass through slots or holes 4 in end plates 2, 3 bearing against the ends of the pipe, the rods being tensioned to the desired extent and gripping members 5 bearing against the outer surfaces of the plates 2, 3 being applied to the ends of the rods. A high-tensile steel wire 7 is circumferentially wound under tension and over the rods 6 to grip or bind the rods against the surface of the pipe to prevent any substantial loss of tension in the rods, the ends of the wire being anchored and the rods being severed adjacent the inner surfaces of the plates so that the plates and gripping members may be re-used. A final coating of concrete may be applied to the pipe. In a modification, the rods 6 are replaced by a continuous length of rod passed backwards and forwards along the length of the pipe and around anchorages provided at or near each end of the pipe.

Filed: 1955-03-18
Abstract: 793,538. Helicopter rotors. FAIREY AVIATION CO., Ltd. March 16,1956 [March 18, 1955], No. 8019/55. Class 4. In a helicopter having two or more pairs of rotor blades all of the blades may be folded rearwardly over the fuselage by arranging the connections to the hub of one pair of blades at a level spaced vertically from the level of connections to the hub of the blades of the other pair(s). Each blade is connected by a hinge 7 to an extension arm 6 of the hub for folding movements and it is made fast to the arm by a releasable pin connection 8 which may be operated manually, electrically, pneumatically or hydraulically. In the preferred embodiment the pin 8 is secured to the piston of a hydraulic actuator 11 controlled from the cockpit through a line 15. The lower end wall of the actuator cylinder is spaced sufficiently from the upper surface of arm 6 to ensure that the portion of the pin which may become scored does not enter the cylinder. When folded one pair of blades 1, 3 are spaced above the other pair 2, 4. The axes of hinges 7 may be so inclined to ensure that in folded position the space between the blade tips of different pairs is accentuated and in extended position the tips will lie substantially in a common plane. A brake may be provided to stop the rotor in the correct position, shown in Figure 1, for blade folding.

Abstract: 404,498. Compensating current meters for temperature errors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) March 17, 1933, No. 8154. Convention date, March 18, 1932. [Class 37.] In circuits employing rectifiers 10-13, more particularly of the dryplate type, so as to utilize D.C. instruments for measurement of current and voltage in A.C. systems, a further rectifier 15 with the same temperature characteristic is connected in shunt with the instrument 14. The effect of this is to tend to bye-pass to the instrument more current on rise of resistance with temperature and so compensate for a similar rise in the main rectifiers 10-13. In the example shown, as arranged for measuring voltage, series and shunt resistances 16, 17, 18 are also employed and the compensating rectifier 15 is constructionally embodied with the other rectifiers 10-13. Specification 371,443 is referred to.

Upon tilting the tube the bubble 30 progressively uncovers the electrodes 25 (say), thus increasing the resistance in the circuit containing the electrodes 25, 28 and finally breaks the circuit when the electrodes are completely uncovered. In the modification shown in Fig. 6, the electrodes 25, 26 are replaced by a single electrode 52 projecting into the middle of the bubble which is thus able either to increase or decrease the resistance between the electrodes 52, 53 according to the direction of tilt.

The flap i is secured to a. shaft h which carries two arms k, l, the former being attached to a weight m and the latter formed with an eye through which passes a rope n kept taut by a weight o. The rope n passes over a pulley k and is wound on the shaft of a pinion d which engages a rack c on the door b and is operated by a handwheel f. As the door b opens the rope n is wound on the shaft of the pinion d and the flap i remains under the action of the weight m, in contact with the edge of the door b; when the latter has accomplished about half of its travel the weight o contacting with the eye on the arm l, reverses the motion of the flap i and causes it to return to the vertical position. The cylinder a is fed from a hopper t closed by a sliding valve q.

Title: Improvements in the regulating of follow-up mechanisms

Abstract: 582,181. Follow-up systems. ENGLISH ELECTRIC CO., Ltd., and JOWETT, W. G. May 31, 1943, No. 8646. [Class 40 (i)] In a follow-up system, the motor driving the follower is controlled by a speed regulator, the movement of which depends on the angular deviation of the master member and follower and also on their relative speed, the latter factor being- introduced by the use of an eddycurrent brake. As shown, the sun-wheels 2, 4 of a differential 3 are driven respectively by the control shaft 1 and the servomotor 34 so that the deviation is imparted by the, planetwheels 9 to the sun-wheel 11 of a second differential 12, of which the other sun-wheel 14 is geared to the speed regulator 15. The deviation is also applied to a magnet system 20 which induces eddy currents in a metal disc 21 whose shaft is constrained by a spring 23, so that a deflection proportional to the speed of rotation of the magnet system is imparted to the planet-wheels 27 of the differential 12, this factor tending to return the speed regulator to its neutral position. The speed regulator 15 controls the current in the opposed field windings 30, 31 of a generator G which supplies the motor 34 on the Ward-Leonard principle. If the follower is driven hydraulically, the regulator may be a valve which applies fluid pressure to one side or the other of a piston of the hydraulic servomotor.
