Title: A jointed transmission shaft, more particularly a propeller shaft for motor vehicles
IPC: F16D3/50
Filed: 1956-11-09
Abstract: 801,998. Slip couplings. GELENKWELLENBAU G.m.b.H. Nov. 9, 1956 [June 13, 1956], No. 34277/56. Class 80 (2). A torque-limit coupling between the two articulated halves of a divided propeller shaft on a motor vehicle comprises in an outer shaft member 13 elastic elements 15 which compress two, four or six shoes 9 on to an inner shaft member 8 to grip a coupling pin 11 or ball in a groove in the shaft 8. Excessive torque cams the pin 11 out of the shaft groove, expanding the shoes about a hinge 12 and permitting the shaft to slip through 360 degrees. In Fig. 2, the outer shaft member is in four sections united at 14 and carried in a casing 16. In Fig. 4, not shown, the elastic members are directly carried in a rectangular sectioned outer shaft member and there are four pressed shoes equivalent to those 9 of Fig. 2, and four coupling pins 11 between their adjacent ends. Fig. 5, not shown, has two such pressed shoes, two coupling pins and a cylindrical outer member having pressed-in portions overlying gaps in the elastic members. In Fig. 3, not shown, the outer surface of the coupling pin 11 is wedge-shaped to conform to the adjacent inner faces of the shoes 9.

Title: Improvements in or relating to the starting of rotary synchronous phase transformers
IPC: H02K47/30
Filed: 1929-11-11
Abstract: 331,173. Kando, K. Nov. 13, 1928, [Convention date]. Rotary transformers.-A starting device for a rotary synchronous phase transformer, particularly a variable secondary voltage machine, comprises a two-phase induction motor, one phase winding of which is in series with the primary winding of the transformer, and the other phase winding is connected to an auxiliary winding having a common magnetic field with the primary winding of the phase transformer. In the form shown, the two windings W1 W2 of the squirrel-cage starting motor M are connected in series with the primary winding p and to the auxiliary winding Z respectively of the transformer A, the winding Z being in the same field as the primary p. Owing to the high internal reactance of the winding p, obtained by the provision of magnetic shunts in the transformer stator slots, the phase difference between the two windings on the motor M will be sufficient to give the necessary starting torque. When the phase transformer is running, the winding W1 may be short-circuited and the winding W2 disconnected by the switches k1 and k2 respectively. These switches may be operated automatically, e.g. by a relay controlled by the secondary voltage of the phase transformer.

Abstract: 1475805 Pinning extruded film IMPERIAL CHEMICAL INDUSTRIES Ltd 14 July 1975 [5 Aug 1974] 34337/74 Heading B5B [Also in Division H1] In manufacturing a polymeric film, e.g. of PTFE or a wide variety of polymeric or copolymeric plastics, an extruded molten film is passed across a grounded cooled casting surface to which it is electrostatically adherent; an electrode being positioned proximate to the contact region of the film and the surface to deposit charge on the film and being energized with alternating voltage of asymmetrical or symmetrical waveform such that the voltage exceeds corona inception for at least 75% of each half cycle and discharge is inhibited for at least 10 Ás per half cycle; and the frequency does not exceed that at which positive and negative charges of the electrode are prevented from traversing the film to electrode space before polarity change of the electrode voltage. Film is extruded through a slotted die spaced closely to the casting surface, which may be a moving belt or a smooth metal, e.g. steel roller which is water cooled to a required temperature. A pinning electrode is disposed traversely of the film proximate to the contact region of the surface. The electrode may be of wire, knife edge, or comb form made of, e.g. stainless steel, tungsten, nickel iron alloy or chrome alloy with its marginal regions insulated with, e.g. PTFE. A wire electrode may be continuously drawn across the film from a new supply, or may circulate continuously through a cleaning bath to remove deposits. Alternatively a gas or air blast may be directed between the electrode and the film, or the electrode may be heated to prevent deposition of foreign matter. The applied voltage between the electrode and the drum may be of a waveform which is asymmetrically sinusoidal, square wave, trapezoidal wave, or modified squarewave or trapezoidal waveform derived from a pulse generator, power amplifier, and transformer (Figs. 1 to 4, not shown). Reference has been directed by the Comptroller to Specifications 1,446,596 and 1,129,136.

Abstract: 1,022,788. Dosimeter systems. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 3, 1963 [Sept. 11, 1962], No. 34657/63. Heading G1A. A dosimeter system for determining the neutron dose received by a human-being from a radiation incident is constructed so as to be portable, to take into account the time between the incident and the test, and to be capable of rapid and simple operation. The system includes a portable battery-powered detector unit consisting of a probe coupled by flexible leads to power supply and indicator assembly. The probe includes a sodiumiodide scintillator crystal associated with a photomultiplier and wrapped in insulating tape and a lead sheath. The complete probe is aluminium cased. The photo-multiplier output is fed back to amplifier stages and an indicating meter. The meter circuitry includes switched potentiometers allowed for correction of the meter reading in view of the time that has elapsed between the incident and the test, a further switch changing the value represented by full scale deflection, and a potentiometer to enable background radiation to be cancelled out. The human-being involved in the incident is required to carry small pieces of cadium-backed copper foil so placed that at least one is directly irradiated, four sewn into a waist belt are suggested. In operation the system is zeroed and the body sodium-24 reading, adjusted for decay since the incident, determined. The direct meter reading is arranged to be correct for an average neutron energy of 2 Mev. To correct for the actual average radiation energy a reading is also taken onthe copper foil giving the largest response and the ratio of the sodium 24, copper-64 readings is applied to a graph (an example of which is shown in Fig. 4 (not shown) of the drawings) to obtain a correction factor. The product of the Sodium-24 reading and the correction factor gives the actual radiation dose received.

Title: Improvements in or relating to aerial and associated feeder arrangements

Abstract: 490,192. Aerials. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 21, 1937, No. 35421. Convention date, Dec. 21, 1936. [Class 40 (v)] An aerial is matched to a feeder for any desired wavelength by making the aerial of variable effective length so that the aerial resistance may be made equal to the feeder image impedance; a variable reactance in parallel with the feeder at the foot of the aerial, neutralizing the aerial reactance. The aerial, Fig. 2, consists of a wire rope 3, 3<1>, 3<11>, 3<111>, passing over pulleys 6, 7, 8, 9 and closed on itself by an insulator 5. The feeder 2, 4 is connected to pulley 6, and an endless wire rope 10 together with the side 3<11> of the aerial loop form a lecher-wire system in parallel to the feeder. Rotation of pulley 12 alters the length of the lecher pair by shifting the shortcircuiting member 13. The effective radiating length 3<111> from pulley 6 to the insulator 5 is similarly adjustable. The aerial and lecherwire may be formed of one wire rope, Fig. 3 (not shown), in which case a linear relation results between aerial length and length of short-circuited line. If more accurate matching is required with a single manual control, pulleys 9, 12, Fig. 2, may be mechanically coupled through a suitably shaped cam. To reduce the capacity to earth of pulley 6 an insulating member carrying a number of small pulleys, Fig. 4 (not shown), may be employed. Fig. 5 shows an embodiment of the invention in which the effective length of the aerial 3 is adjusted by the sliding tubular conductor piece 17. The adjustable reactance is formed by conductor 18, slidable on the aerial at 19 and the short-circuiting member 13.
