Title: Starting Arrangement for a Single-Phase Motor
IPC: H02P1/42
Filed: 1968-05-20
Abstract: 1,164,072. Control of A.C. motors. DANFOSS A.S. 20 May, 1968 [27 May, 1967], No. 23898/68. Heading H2J. A single-phase motor has main and starting windings 2, 3, and a PTC-resistor is connected in series with the starting winding. This resistor has a stable operating point on either side of the peak of its current-voltage curve, the resistor being at the low-value stable position when it is heated only by the starting current. A heating resistor 8 is connected across the supply lines, and delayed by its mass and by a thermal insulator 9, affects the resistor 7 only towards the end of a selected period. The resistor then changes over to its other stable operating point so that the starting current is reduced to a low value. The resistor 8 may be energized for the entire running period of the motor, or may be switched on only for a brief interval towards the end of the starting period. The resistor 8 may carry the main winding current, or it may be in parallel with the starting winding.

Abstract: 644,136. Transmission, impedance, phase and frequency measurement. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. Aug. 29, 1947, Nos. 23962 and 27036. [Class 37] [Also in Group XL (c)] An apparatus for wave analysis or for frequency and phase response measurement comprises a homodyne demodulator 12 to which oscillations to be analysed or oscillations for frequency response testing from source 10 are applied via path 11 and via a variable frequency filter circuit. This filter circuit comprises two modulators 13, 14 to which the oscillations are applied, followed by low-pass filters 15, 16 and modulators 17, 18, a local oscillation having two output components in phase quadrature being applied respectively to the first two modulators 13, 14 and respectively to the two modulators 17, 18. In the arrangement shown, the combined outputs from the second modulators are applied through a low pass filter and phase adjuster to the main demodulator, which in turn feeds a low pass filter 21 and output meter 22. The variable frequency filter has a narrow pass-band whose mid-frequency is varied by adjusting the frequency of the local oscillator 9. When measuring frequency response the apparatus to be tested is inserted at 23 and the test and local oscillators are varied together. The response is measured by substituting an attenuator for the equipment under test and the phase response is determined by calibrating the phase adjuster 20 which is adjusted for maximum reading of the meter 22. For wave analysis the wave is applied at 10 and the local oscillator is varied to adjust the filter to select the component to be measured, the meter 22 indicating the resulting D.C. output.

Title: Improvements in dog clutches and change speed gears
IPC: F16D11/10
Filed: 1933-08-30
Abstract: 422,802. Dog clutches; variablespeed gearing. LEYLAND MOTORS, Ltd., and NAYLOR, J. T., Motor Works, Hough Lane, Leyland, Lancashire. Aug. 30, 1933, No. 24083. [Class 80 (ii)] In a dog clutch, the whole opposed end faces of the two members are either inclined at a small angle to the plane normal to the axis of rotation, as shown in Fig. 1, or are made of mating helical form, the abrupt step between the beginning and the end of the helix being rounded off, whereby engagement is prevented if overrunning occurs. By arranging, in the first case, that the most axially extending point of the end face is at the centre of a tooth, engagement is prevented if overrunning in either direction occurs. The applications to a two-speed gearbox is shown, the slidable double dog member 8 being controlled by a yoke pivotally connected at 13 to one arm 14 of a lever, the other arm 15 of which is connected by a spring 16, which in its movement passes through a dead point, to an arm 17 connected to an operating lever by a link 18. The travel of the arm 17 is limited by stops engaging the operating lever and by a spring detent 21 co-operating with notches 22 in a sector 20 formed on the arm 14.

Title: Improvements in and relating to disc brakes
Inventor: PARNELL FRANK GORDON
IPC: F16D65/14
Filed: 1961-07-04
Abstract: 945,846. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. July 4, 1962 [July 4, 1961], No. 24133/61. Heading F2E. A disc brake comprises a pair of support members mounted for pivotal movement in a plane normal to the plane of rotation of a disc, a pad or pads secured to the free end of one support member for engaging one side of the disc, a pad or pads associated with the free end of the other support member and movable relatively to the other support member upon operation of brake actuating means both towards the disc and laterally, in response to drag forces, the support members being interconnected by coupling means and the arrangement being such that upon operation of the actuating means the pad or pads applied thereby to the disc exert a reaction force on the associated support member to pivot both support members whereby the pad or pads on the opposite side of the disc are applied. In one embodiment, Figs. 1, 2, pads 3, 4 disposed on opposite sides of an annular disc 1 carried by wheel assembly 2 are associated respectively with support members 5, 6 pivoted to bracket 8 on stationary axle casing 7. Pad 3 is fixed to member 5 and pad 4 has a backing-plate 9 disposed for limited lateral movement in relation to stops 20 on the free end of support member 6. An hydraulic cylinder 10 is formed integrally with member 6 and contains a piston 11 acting through plunger 15 on backing-plate 9 to apply pad 4, the direct reaction acting on the support member 6 to apply pad 3 via coupling-rod 16, adjustable by nut 17. As a result of drag forces on pad 4, plate 9 moves laterally and acts on rollers 19, which are journalled on the member 6 and engage recesses 18 in plate 9, so that a servo action results, increasing the braking force. A piston-rod 21 extends from piston 11 through a seal in the closed end 14 of the cylinder to a manually operated lever 22 for applying the brake manually. In a second embodiment, Fig. 3, support members 30, 31 in the form of rockers are pivoted at 32, 34 and interconnected by adjustable coupling link 47. Pad 27 is fixed to member 30 and pad 28 has a backing plate 29 mounted for lateral movement in a fixed caliper 35 secured by bracket 36 to axle casing 33. A cylinder formed within the caliper contains a piston 37 connected by a link similar to link 47 but non-adjustable to the plate 29. When pad 28 is applied to the disc 25 by admission of hydraulic fluid to the cylinder, the drag forces cause plate 29 to move laterally and act on rollers 45, which are journalled on the member 31 and engage recesses in plate 29, so that pad 27 is also applied and a servo action results.

Abstract: 495,734. Drying gases; refrigerating. TENNANT, W. J. (Dow Chemical Co.) Sept. 6, 1937, No. 24326. [Classes 29 and 34 (i)] A method of dehumidifying a gas, such as air, comprises contacting the moist gas with an aqueous solution of a mixture of lithium bromide with one or more of the salts lithium chloride, calcium chloride, and calcium bromide in such proportions that the solution if saturated would have a lower vapour pressure than a saturated lithium bromide solution at the same temperature. The invention also comprises a method of cooling water by partial evaporation thereof under sub-atmospheric pressure, the water vapour being absorbed by an aqueous solution of a mixture of lithium bromide with one or more of the salts lithium chloride, calcium chloride and calcium bromide, in the same proportions as required for the method of dehumidifying a gas. The proportions of the salts from which the solutions can be made may be ascertained by the chart shown, in which the corner A represents one mole of calcium chloride, B one mole of calcium bromide, C one mole of lithium chloride and D one mole of lithium bromide. A point E, for example, represents a solute composition containing À3 mole of calcium chloride and À7 mole of calcium bromide. The curved lines or isobars 11, 12, 13, 14 are lines traced by a point representing solute compositions of solutions saturated at 90‹ F, all of which on the same curve have been found to have substantially the same vapour pressure. The solute compositions in the area between the two lines 11 representing the vapour pressure of 1À8 mm. and the intersected portions of the sides BD, CD, all produce solutions having a substantially lower vapour pressure than 2À1 mm. which is that of saturated lithium bromide solution at the same temperature. The lowest vapour pressures are obtained by the solutions, the solutes of which are indicated by points within the isobar 14.
