Abstract: 357,005. Rolling tubes. VOLLMER, A., 75, D³sseldorferstrasse, Hilden, Rhineland, Germany. Nov. 17, 1930, No. 34611. Convention date, Feb. 8. [Class 83 (iv).] The external thickening at the rear end of a tube after pilgering over a mandrel 2 is converted to an internal thickening by withdrawing the mandrel and fitting over its shoulder 3 an annular abutment 4 against which the thick end abuts while it is being rolled down to transfer the thickening to the inside. The mandrel has a smaller diameter end 8. The abutment 4 has a conical projection 5 which engages the end of the blank and the back sleeve 6 of the abutment helps to hold the tube and thickening central during working. 7 is the stripping sleeve.

Convention dates, Dec. 8, 1931, May 6, 1932, and May 21, 1932. [Class 98 (i).] A device for protecting from access of light a photographic film wound upon a spool c comprises a casing b of flexible material, e.g. stiff paper or cardboard having a longitudinal slit e extending between its ends and lined with velvet &c. in which the spool flanges are embedded ; the casing being prevented from opening by end caps or rings a wholly or partly embracing the ends of the casing. As shown, the cap a is slotted at d to clear the slit e; alternatively the cap may be bulged to cover the slit. To facilitate breakage of the casing, for removal of the spool, the cap is notched at the part opposite the slit. The velvet &c. may be applied to a rectangular piece of paper, cardboard &c. which is then brought to tubular form and slid into the casing. To facilitate threading of the spool, the slit is aligned with the spool slot or other attachment means by the use of registering marks on the casing and spool core or flange. Specification 371,706 is referred to. The Specification, as open to inspection under Sect. 91 comprises also a flexible casing retained in shape by resilient rings f, Fig. 3 (Cancelled), or by means of clamps embracing the longitudinal edges of the slit. This subject-matter does not appear in the Specification as accepted.

Title: System for determining the point of break in an electrical conductor
IPC: G01R31/08
Filed: 1946-12-03
Abstract: 622,957. Capacitance measurements. UNIVERSAL ELECTRONIC LABORATORIES, Inc. Dec. 3, 1946, No. 35791. Convention date, Dec. 16, 1944. [Class 37] For locating breaks in a telephone line by measuring the capacitance at the terminal of a pair of wires a bridge is so arranged that a standard slide-wire calibration for measuring a pure capacitance is approximately correct in spite of the resistance of the wires. The bridge has the ratio arms formed by a resistance 12 with a sliding contact c, a third arm formed by a standard condenser 6 having a reactance large compared with the slide-wire resistance 12, and the fourth arm formed by the line under test which has a capacitance Cp to the fault shunted by the resistance Gp of the wires. An alternating voltage having a frequency of about 20 cycles per second is applied across the diagonal c, b, and the other diagonal a, d is connected to a ring modulator 30 which causes the galvanometer 8 to give a pull indication when the detector voltage is either zero or very nearly in phase with the voltage applied to the bridge. The voltage applied to the bridge is generated by a phaseshifting oscillator circuit containing an oscillator T1 which generates a low frequency of about 20 cycles per second. The phaseshifting feed-back circuit consists of elements 2-1, 18-2, 2-2, 18-1, 3-2, 33, 21-2, 3-1 and 18-3 and causes the voltage appearing at the plate of the valve T1 to be shifted 180 degrees and applied to the grid of the same valve. A load resistor 21-1 is connected in the plate circuit of the oscillator valve T1. A blocking condenser 4 is connected in the circuit from the oscillator valve T1 to an amplifier valve T2. Resistances 19, 18-4 form a voltage divider to reduce the voltage applied to the grid of the valve T2. In the output circuit of the valve T2 is a load resistor 13, a blocking condenser 5 preventing D.C. passing to a transformer 29. The points c1 and the lower end of the resistance 13 are connected across the diagonal b, c, of the bridge. The ring modulator 30 consists of four dry rectifiers connected between the points u, v, w, x, as shown. Two equal resistors 24-1, 24-2 are connected across the points v, x. A potentiometer 16 having a sliding contact y is connected between two resistors 32-1, 32-2 and is adjusted so that the slider is electrically balanced between the points u, w. The galvanometer 8 is connected between the points v, x, the points y, z being connected to the diagonal points a, d of the bridge. If there is applied simultaneously between the terminal pair u, w and between the terminal pair y, z two voltages which are in phase quadrature, the galvanometer 8 indicates zero. The circuit between the point c1 and the terminals u, w, shifts the phase of the oscillator voltage by 90 degrees, hence the galvanometer 8 indicates zero when the phase of the voltage on the bridge detector terminals a, d is in phase with the voltage driving the bridge between the terminals b, c. A variator 31 is shunted across the galvanometer 8 to prevent overloads.

Title: Electromagnetic friction coupling
IPC: F16D27/115
Filed: 1956-11-23
Abstract: 837,884. Friction clutches. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Nov. 23, 1956 [Nov. 23, 1955], No. 35876/56. Class 80 (2). An electromagnetic friction clutch of the stationary magnet-type has two sets of friction surfaces, one, 13, 14, a magnetic set, forming part of the flux path and therefore engaged both magnetically and frictionally, the other 23, 24, a mechanical set, engaged only by the mechanical thrust acting magnetically on the first set, and the friction surfaces of the magnetic set comprise more than one pair of a material of less wear resistance than that of the mechanical set. Engaging pressure for the mechanical set is therefore always available in spite of overall wear and it is possible to select materials for the mechanical set which have high wear resistance without regard to magnetic properties. The area of the mechanical set is also greater than that of the magnetic set so that unit pressure and hence wear are also higher in the latter. The magnetic set comprises discs 14, 13 splined respectively to a non-magnetic input member 18 and a composite disc 4, 5, 6 fast to a freely mounted member 1 rigid with an output member 27. Energizing the winding 8 of a stationary magnet 10 attracts a presser-plate 15, fast on the input member 18, thus engaging the magnetic plates 13, 14, and also, by thrust on the input member 18 and a presser-plate 25, butting at 26 thereon, engaging the plates 23, 24 of the mechanical set which are splined alternately to the input and output members 18, 27. In the magnetic set the ring 5 is non- magnetic, the remaining parts 4, 6, 10, 13, 14, 15 being magnetic. Sectional windows 31 are provided in the discs 13, 14 and may replace the ring 5. The discs of the magnetic set may comprise steel or cast-iron and may have adhered to one or both sides by sintering or otherwise a facing of sintered metal; or the discs themselves may be sintered and have a facing of cast-iron or steel.
