Title: Improvements relating to automatic adjustment mechanism for vehicle brakes
IPC: F16D51/48
Filed: 1954-12-08
Abstract: 747,169. Internal shoe-drum brakes. GENERAL MOTORS CORPORATION. Dec. 8, 1954 [Jan. 5, 1954; Jan. 5, 1954], No. 35534/54. Class 103 (1). In an internal shoe-drum brake, automatic adjustment for shoe clearance is carried out by a pendant member 50 which is caused to be moved downwardly when the brake shoe movement becomes large by the interengagement of an inclined slot 56 thereon with a pin 25 on the back plate so that a spring pawl 72, Fig. 2, moves over a tooth on the ratchet wheel 41 and turns it to rotate a screw threaded member between the shoe ends. In a modified arrangement the pendant member 50 may be moved upwardly to adjust the brake. Fig. 8 shows an arrangement in which a bi-metallic element 100 is secured to the spring pawl 70 so as to flex the end 72 away from the ratchet wheel if the brake should attain such a temperature that there will be appreciable expansion of the brake drum such as to cause false adjustment.

Title: Cathode-ray tube for producing an elongate spot
IPC: H01J29/62
Filed: 1971-07-29
Abstract: 1352217 Cathode-ray display tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 July 1971 [1 Aug 1970] 35655/71 Heading H1D A cathode-ray tube includes cathode 8, grid 9, anode 10, acceleration electrode 11, focusing electrode 12 and target, the grid having elongate opening (e.g. elliptical opening 15, Fig 3, not shown) so that the gun forms an astigmatic lens such that in the plane containing the longitudinal axis of the aperture and the gun axis the electrons may be focused at a point spaced from and on the gun side of the target while in an orthogonal plane the electrons may be focused on the target, the anode having an elongate opening the length direction of which is at right angles to the length direction of the grid aperture. The acceleration electrode may form part of the focusing lens 31. The anode opening may widen stepwise and may develop into a rectangular opening towards the target as at (16), (17), (Fig. 2). Application to index type 110 degree deflection colour TV tubes is described wherein the target comprises parallel phosphor strips separated by guard bands and with index bands, wherein the beam spot is elongate in the strip direction to attain adequate brightness without saturation. The construction enables beam current to be increased without increase of beam width. The above construction inhibits effects due to deflection astigmatism and the longer distance travelled by electrons emitted further from the gun axis, the latter effect accentuated by spherical aberration due to the sharp equipotential surface bend on the target side of the anode opening unless the latter is widened. Fig. 1 (not shown) includes strip layer (4), metal light reflective layer (5), and index strips (6) emitting u.v. on electron incidence and further accelerator (13) may be included. Beam shapes are considered in relation to Figs. 5 to 12 (not shown). Constructional dimensions and electrode potentials are given. The cathode may be an osmium plated "L-type" and the inclination of the spot (Fig. 12) may be reduced by separate connecting means.

Title: Change-speed gearing for lathes and other machine-tools
IPC: B23Q5/14
Filed: 1934-12-14
Abstract: 429,741. Controlling change speed gearing. HERBERT, SIR A., LLOYD, A. H., and HARRISON, H. T., c/o Herbert, Ltd., Canal Road, Edgwick, Coventry. Dec. 14, 1934, No. 35908. [Class 80 (ii)] Selector mechanism for controlling changespeed gearing for lathes and other machine tools comprises the twin rotary and contracting profile discs 40 described in Specification 382,784, but adapted for operating sliding gears instead of friction clutches. A driving- shaft 12 is adapted to be connected by a disc clutch 13 to a shaft 17 which drives on through a reversing-gear in series with three twospeed gears with sliding toothed change wheels. These three two-speed gears in series are controlled respectively by three stems 39, and eight forward speeds are effected by closing in on these stems the present profile discs 40. In a preselector arrangement shown, the discs 40 are held apart from the stems 39 while the gearing is in motion and are present from a turnable dial 50. A cam barrel 51 is then turned one revolution from a handwheel. A control collar 15 is first slid by a cam 53 against a disc brake 16 to arrest the transmission. A cam 52 then operates twin levers 43 in unison to throw towards each other collars 41 which press against the backs of the profile discs 40 through springs 42. The stems 39 are thus operated yieldingly towards the selected serial combination, and the gear teeth to be enmeshed have sharpened ends to facilitate change of mesh. The cam 53 then by moving the collar 15 engages the clutch 13 and the drive proceeds on the new ratio. The cam 52 then separates the twin collars 41 and discs 40. In a modified preselector arrangement, the cam barrel 51 is replaced by a trip lever. In another arrangement, the profile discs 40 are not withdrawn after closing in on the stems 39. This arrangement is not preselective since selection cannot be effected until the discs have been separated for the purpose. The profile discs may be contracted by suitable power means.

Abstract: 1,152,020. Control of A.C. motors. DANFOSS A/S. 9 Aug., 1967 [29 Aug., 1966], No. 36519/67. Heading H2J. [Also in Division H1] A bimetal starting switch for a single phase asynchronous motor is opened by a first heater 7 of high thermal capacity, the heat stored therein being sufficient to keep the switch open until a second heater 9, shunting the contacts, heats up to maintain the contacts open for the remainder of the time that the motor is energized. The first heater 7, of carbon or silicon carbide, is in series with the bimetal 10 and the resistive type start winding 1 of the motor and preferably its resistance is 50% of the total. The second heater 9 preferably has a high positive temperature coefficient; it remains in series with the winding 3 but reduces the current to a negligible value. As shown, the heater 9 is annular, and the bimetal strip 10 is attached to it by a rivet 11. In an alternative arrangement (Fig. 2, not shown), the first heater is placed between two bimetal strips, each of which carries one of the contacts, and this heater is not part of the shunt path of the second heater.

Title: Improvements in or relating to line-testing systems for telecommunications systems
IPC: H04B17/40
Filed: 1964-09-07
Abstract: 1,031,448. Supervising unattended repeaters. SIEMENS & HALSKE A.G. Sept. 7, 1964 [Sept. 6, 1963], No. 36574/64. Heading H4R. [Also in Divisions G1 and G4] In a transmission system having separate lines for go and return paths in which the lines are interconnected by a series of couplings at a series of mutually spaced positions along the lines, e.g. at unattended repeater positions, and a pulse applied to the go line at a terminal station is passed to the return line through each of the couplings and received back at the terminal station as a series of pulses spaced by the transit time of the pulses from one coupling to the next, a transmission property of each coupling is variable in response to a fault criterion in a section of the line adjacent to that coupling. Preferably the pulses applied to the line for fault-finding occupy a frequency band adjacent to that used for the information transmission, the repeaters passing both bands, and the coupling networks, which are coupled to the lines by high impedance networks, include band-pass filters passing only the band occupied by the test pulses. The transmission property of the coupling, e.g. the attenuation, may be varied to indicate faults in the repeater itself or in the line. For example, by a manometric pressure dependent contact across the input or output of the coupling network a leak in the cable may be located. In such an arrangement the operation of the contact may be arranged to send a signal, common to all repeaters, to initiate the pulse-testing arrangement.
