Patent GB-979416-A (GB)
Title: Voltage regulators
Inventor: WILKINSON DONALD FREDERIC
IPC: H02J7/16
Filed: 1961-02-22
Abstract: 979,416. Automatic voltage control C. A. V. Ltd. Jan. 30, 1962 [Feb. 22, 1961], No. 6430/61. Heading G3R. In a voltage regulator of the kind described in Specification 979,415 and comprising a first transistor 6 controlling current flow to the field winding 3 of an alternator, a second transistor 8 which when conductive controls the degree of conduction of transistor 6, and means, including a Zener diode 21, for rendering transistor 8 conductive when the output voltage of the alternator exceeds a predetermined value, there is provided a third transistor 22 having its collector-emitter terminals connected in series with the base terminal of transistor 6, the base terminal of transistor 22 being connected over an RC filtering circuit 24, 26, 27, 28 and a diode 25 to a terminal 23 connected to one phase of the alternator. When the alternator is operative, transistor 22 is rendered conductive by the rectified signal from terminal 23 and transistors 6 and 8 operate to regulate the output voltage of terminals 1, 2. When the alternator is inoperative, however, transistor 22 is non-conductive and cuts off the rest of the circuit from terminal 2; if the alternator is used to charge a battery this prevents leakage current flowing through the regulating and field circuits.

Title: Fluid control valves
Inventor: RIGHTON JOSEPH JOHN
IPC: F04B1/32
Filed: 1960-02-24
Abstract: 966, 744. Fluid-pressure servomotor control systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Jan. 26, 1961 [Feb. 24, 1960], No. 6443/60. Heading G3P. A control valve 33 in a swashplate pump is rotated through its loading spring 34 from a rotary part 6 of the pump to avoid static friction. In the position shown in Fig.1, fluid from the inlet of the pump flows through passages 36, 37, 31, 24 and 25 to act on a pair of pistons 14, of which only one is shown. When the pressure at the pump output reaches a predetermined value it acts through passages 26, 23 and 32 on the right hand end of the valve member 33 to displace it to the left to interrupt communication between the pump inlet and the pistons 14 and to allow the outlet pressure in passage 23 to act through the passages 24, 25 on the pistons to rotate the swashplate about its pivot 13 and reduce the pump output. The movement of the valve member 33 is assisted by the difference in fluid loading on the adjacent faces of the lands 33a, 33b once the port 23 is uncovered. A spring-loaded, non-return valve is fitted in the pump outlet.

Title: Improvements relating to fluid pressure braking apparatus for vehicles
IPC: B60T11/10
Filed: 1944-04-07
Abstract: 580,111. Controlling motor vehicles. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. (Bendix- Westinghouse Automotive Air Brake Co.). April 7, 1944, No. 6524. [Class 79 (v)] [Also in Group XXXIV] In a braking-system for vehicles, the movement of the accelerator to close the throttle causes the operation of electro-pneumatic means which produce a partial application of the brakes, and subsequent operation of the brake pedal renders the electropneumatic means ineffective. As shown, the accelerator pedal 16 controls' a selflapping valve 15 and, when depressed, admits air to the cylinder 6 and opens the throttle 5. The pressure in the branch pipe 90 of the pipe 14 depresses the rod 91 and moves a contact arm 70 against the contact 69, the frictional pivot 72 retaining the arm in a set position. The contacts 69, 70 are in circuit with a magnet valve 36 and fluid pressure valve 55, the contacts 59, 62 of the latter being kept open by pressure in the branch pipe 68, and being allowed to close when, on raising of the pedal 16, the pipe 14 and cylinder 16 are vented through the pipe 17. When the accelerator moves to close the throttle 5, the magnet valve circuit is closed and the valve 42 is moved to admit air from the reservoir 11 through a reducing- valve 51, pipes 49, 48, valve 30 and pipe 28 to the brake cylinders 18. The valve 30 comprises a sliding valve member 35, which, when full reservoir pressure is admitted by the depression of the brake pedal 22 is forced up to close the port 32 and to establish connection between the pipes 26, 28. At the same time, the branch pipe 86 supplies air to the cylinder 82 and moves the arm 70 to break the contacts 69, 70, the auxiliary braking-means being thus rendered ineffective when the accelerator is again depressed to open the throttle. A partial brake application is indicated by a light 103 controlled by a valve 107 of construction similar to the valve 55. A full brake application is indicated by a lamp 92 controlled by a switch 93 responsive to the air pressure admitted to the brake cylinders.

Title: Method and apparatus for the acetylene torch cutting of thick-walled hollow metal bodies
IPC: B23K7/00
Filed: 1960-02-25
Abstract: 940,961. Cutting by fusion. MANNESMANN A.G. Feb. 25, 1960 [May 15, 1959], No. 6619/60. Heading B3V. In order to prevent the interior of a hollow workpiece being choked with dross during acetylene torch cutting, one or more torches are pivotally adjusted so that they remove segmentshaped portions and are then rotated around the workpiece to extend the cut-away segments and so leave a residual annular portion which is then cut away by further pivotally altering the direction of the cutting torches and subsequent circular movement of the torches. In a machine for cutting a thick-walled tubular ingot 2 as it issues from a continuous casting-machine, a pair of opposed torches 8, 10 are pivotally mounted on a sleeve 24 rotatably mounted on a truck in a casing 4. The sleeve 24 which is water cooled is rotated within the casing by a motor 16. A second motor 18 mounted on the sleeve 24 adjusts the torches 8, 10 about their pivots. The casing 4 is movable in guides 14 longitudinally of the ingot 2 so that the torches 8, 10 can cut the ingot 2 as it issues from the casting machine. After the pre-heating the torches 8, 10 are rotated through 180 degrees whilst set angularly in opposite directions to cut the ingot as shown in Fig. 4b. Subsequently the torches are turned in a few degrees, as shown in Fig. 4e, and rotated back to the starting position so completing the cut.

Abstract: 626,539. Cutting optical glass. PLANET, F., and GUILLERMET, P. March 11, 1947, No. 6793. Convention date, March 13, 1946. [Class 56] Optical glasses are cut by a diamond which is movable radially over a rotary support on which the glass blank is supported, the diamond being moved by a pantograph linkage in accordance with the movements of a follower which contacts with the inner surface of the mounting in which the glass is to be fitted, the mounting being carried on a member which is rotated in unison with the support of the glass blank. If rimless glasses are to be made, a bezel is used to guide the follower. As shown, the frame 1 of the spectacles is secured by a number of adjustable jaws 2 on a rotatable head 3 mounted on a base 4, and a roller 9 on a lever 12 is pressed by a spring 11 into the groove of the frame 1. The lever 12 has an adjustable connection 14, 15, 16 with a lever 17 which carries the cutter 24, a parallel link system 22, 23 ensuring that the cutter moves horizontally. The work is carried on a support 25 to which it is clamped by a rubber member 30. The support 25 has a feathered connection with a head 26 which is coupled by a belt 8 to the head 3, so that, on manipulation of the driving-wheel 7, the frame 1 and the work rotate in unison. The work is pressed against the cutter 24 by a lever 28 which raises the support 25.

Abstract: 748,985. Indicating apparatus. MATERIEL INDUSTRIEL SOC. ANON., and CONSTRUCTIONS MECANIQUES SOC. ANON. March 9, 1954 [March 12, 1953], No. 6802/54. Class 106 (4). [Also in Group XXX] In equipment for measuring and recording the vertical irregularities along a railway track rail, a vehicle frame, Fig. 2, is mounted at one end on an axle 1 fixed thereto and rests by a ball-andsocket joint 6 on a bogie 5 having one fixed axle 4 and an axle 3 pivoted thereto as at 7, Fig. 3, to rotate in a vertical plane transverse to the track, the relative vertical movements between the axle box 8 of the axle 3 and the frame 2 due to the passing of the axle 3 over an irregularity being transmitted directly by means of the sheath 12 enclosing the cable 20 for stylus 14. The relative movements between the axle box 16 of axle 4 and the frame are transmitted to the cable 20 and stylus 14 through a reduction gear 18 to compensate for a component of the relative movement between the axle box 8 and frame 2 due to a consequential vertical movement of the frame 2 relative to the rail during passing of the axle 3 over the irregularity. Action of cable 9 on the end 11 of the sheath 12 in opposition to spring 15 varies the curvature of the sheath secured at its other end to the recording table 13, thereby tightening or slackening the cable 20 in opposition to spring 22 to move the stylus 14 accordingly. Cable 19 from the reduction gearing 18 acts directly on the cable 20 in opposition to spring 21. The cables 9 and 17 are connected to the respective axle boxes by rollers guided in arcuate slots 24 centred on the joint 6, Fig. 3. Specifications 748,984 and 748,987, [Group XXX], are referred to.

Abstract: 1495853 Straps for wrist watches BEAR CO Ltd 20 Feb 1975 [25 Sept 1974 (3) 16 Jan 1975] 7192/75 Heading A3H A strap for a wrist watch comprises a plurality of first strap elements 11, Figs. 5 and 9 each of which elements is pivotally connected with its adjacent element by inserting a pin 17 through flanges 15a, 14, 15b of the elements, and a plurality of second strap elements 12 having grooves 18 of such depth that they accommodate substantially completely within the grooves 18 the first elements 11, wherein the edges of the end portions 18a of the second strap elements 12 are pressed to form teeth 18b to trap and partially cover the first elements 11 while permitting them to have relative pivotal movement. In the assembled form of the strap (when on wearer's wrist) only the second elements 12 are visible and appear to be directly and flexibly connected to one another. Instead of attaching the first elements 11 to the second elements 12 by forming teeth 18b on the elements 12 other means may be employed, such as adhesion by solder or an adhesive or by welding. The pins 17 are prevented from axial movement because their ends engage against the adjacent end portions 18a of the associated elements 12. Some of the second elements 12 have notches 19 to facilitate the removal of some pins 17a to adjust the strap length. In another embodiment (Fig. 11) side edges of the end portions 18a are formed with projections 21 to engage complementarily shaped recesses 20 of the side edges of an adjacent element 12 providing pivotal movement without leaving spaces therebetween to prevent hair from getting caught in the edges. Alternatively the central portion of the second elements 12 may be made smaller in width than their end portions 18a to provide substantial gaps between the adjacent end portions to prevent hair from getting caught in the strap Fig. 14 (not shown).
