Title: Improvements in talking machines
IPC: G11B17/02
Filed: 1928-05-14
Abstract: 317,357. Gramophone Co., Ltd., and Thompsett, H. A. May 14, 1928. Magazine gramophones adapted to play records of various sizes, and having adjustable means for varying the extent of the return movement of the tone-arm to suit the size of record, are so arranged that the tone-arm is moved outwards by contact with a member the extent of whose movement is variable, the outward movement of the tone-arm being limited by a stop member, the position of which is also variable. In the form shown, cams 34, 51, Fig. 5, respectively for lifting and returning the tone-arm, are driven by a gear 5<1> on a plate 5 which is automatically clutched to the turntable spindle 3 in the usual manner. Fig. 2 shows in full and dotted lines the setting of the parts for returning the tone-arm for twelve-inch and ten-inch records, respectively. The return lever 46, operated by a lever 48 engaging by its roller 50 the cam 51, is pivoted at 47 to a stop or positioning lever 54 which rocks about a pivot 55. To return the tone-arm to starting position, the free end of the lever 46 engages a pin 16 depending from an extension 17 on the tone-arm and swings the pin against an auxiliary lever 57 spring-mounted on the free end of the lever 54. Assuming a twelveinch record has been played, the parts are in the position shown in full lines and are automatically moved to the dotted-line position by the engagement of a pin 79 on the cam disc, Fig. 5, with a lever 77 connected at 76 with a link 74. This link is attached at one end to the lever 54 and at the other end engages a bell-crank lever 61, the arm 63 of which then moves from the notch 66 of a spring-controlled detent 67 into a second notch 65. If ten-inch records are played, the setting remains unchanged, but, when a twelveinch record is fed to the turntable, the edge of the record engages a pin 81 on the crank 80 extending from the lever 63 and moves the parts into the full-line position.' The auxiliary lever 57 exerts a spring pressure on the tone-arm to feed the needle into the groove. The tone-arm 14 is lifted about pivots 27, Fig. 4, by the cam 34 engaging a lifting-lever 32 which bears on the lower end of a pin 30 carrying a plate 35 on which rests a pin 36 extending from a member 37 on the tone-arm. Specification 317,358 is referred to.

Title: Hydraulic master cylinder
IPC: B60T11/24
Filed: 1972-03-28
Abstract: 1324308 Dual master cylinders BENDIX CORP 28 March 1972 [12 April 1971] 14435/72 Heading F2F The axial length of a dual system brake master cylinder is reduced by arranging the two pistons telescopically one within another. Thus, the secondary piston 40 which pressurizes space 96 to energize the front brakes 12 over lead 24, slides within the hollow primary piston 38 which is actuated by pedal lever 84 and serves to pressurize space 94 feeding rear brakes 14 over line 26. The pistons are held in the retracted position shown by a preloaded spring 54 which spaces the pistons and by springs 64 and 66 which bias piston 40 to its non-braking position. The preloading of spring 64 is maintained by a cage 74 which is secured by bolt 76 and which has a flange 78. In the released position, shown, this flange and the rim 58 of the secondary piston dislodge valves 114 of conventional design to allow passage of fluid from reservoirs 104 to the spaces 94, 96. These valves are spring-loaded to allow fluid to be sucked into the master cylinder when it is 'pumped' by the pedal.

Abstract: 1,096,459. Vice. F. ARNOLD. April 6, 1965 [April 7, 1964], No. 14632/65. Heading B3B. [Also in Division F2] A toggle mechanism providing high clamping pressures a machine vice 1, comprises two opposed toggle levers, each consisting of three rollers 11, 12, 13 and two struts 15, 16 having semicylindrical recesses (14) (Fig. 3, not shown) each end in which the rollers are supported, which are arranged between an abutment 9, of a U-shaped carrier, and a movable jaw 3, the toggles being brought into action when, after the workpiece is initially gripped between the movable jaw 3 and a fixed jaw 2 by rotating a quick-acting screwed spindle 7, further operation of the spindle causes a large roller 18, fast on a centre rod 10 of the spindle 7, to be axially thrust between and force apart the centre rollers 12 of the toggles. The clamping pressures may be varied by an adjustable stop 24 which has varying height stop faces 25, 26 limiting the movement of the rod 10. The hollow spindle 7 is rotated in a nut 5, bolted at (6) (Fig. 1, not shown) in one of a number of positions along the vice 1 to suit varying workpiece widths, by a handle 8 through a spindle 43 and an overload release coupling formed on the spindle 43 by a disc 46 having a facial wedge shaped tongue 48 spring biased at 47 into a corresponding slot in a nut 44 secured by pins 45 to the spindle 7, the end of the spindle 43 bearing on the outer end of the centre rod 10 such that in operation, rotation of the spindle unit moves the vice jaw 3 into contact with the workpiece and further rotation of the handle 8 releases the outer spindle 7 and nut 44 from spindle 43 which then thrusts through the rod 10 to operate the toggle mechanism. The abutment 9 carries spring loaded bolts 37 whch co-operate with stops 35 in the slide 4 to pre-load the toggles into contact with the centre thrust roller 18.

Title: Improvements in and relating to electric signalling devices particularly suitable for road traffic purposes
IPC: G08G1/085
Filed: 1930-05-13
Abstract: 354,409. Road-traffic signals. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Vickery, H. W. ; 15, Falls Street, Lynn, Massachusetts, U.S.A.) May 13, 1930, No. 14740. Convention date, May 13, 1929. [Class 118 (ii).] In signalling devices for controlling road traffic the electrical signals are operated in sequence by a controller (commutator C) actuated by a motor M, the speed of which may be varied independently for each signal. Means are also provided for overlapping the signals if desired. The commutator C has segments 11 .. 14 connected electrically to rings 15, 16, 17, 16 respectively. Brushes X, Y, Z contact with rings 15, 16, 17 respectively and brush W coacts with segments 11 .. 14. The commutator controls relays T1 .. T4 operating red (R), yellow (Y), and green (G) lamps at the four roads (N, S, E, W) crossing. The motor speed is initially set by rheostat R4. Rheostats R1, R2, R3 are adjusted to control the motor speed for the red, yellow, and green lamps independently of each other, as they are lit up. When brush W touches segment 11 a circuit is closed +ve, 18, W, 11, 15, X, 19, M3, 20, -ve. Magnet M3 is energized and contacts 2 and C2 are bridged to light the red lamps N and S and the green lamps E and W over circuit +ve, 18, 21, C3, 3, 2, C2, lamps, and -ve. Another circuit from 3 also goes through contacts C7 and 7, of relay T3, and through rheostat R1, so that R1 controls the time the lamps just lit remain alight. Similarly, when brush W leaves segment 11 for segment 12, magnets M5 and M6 of relays T3 and T4 are energized to light the yellow lamps on all four roads, N, S, E, W. With brush W on segment 13 magnet M4 of relay T2 lights green lamps N and S and red lamps E and W; whilst with W on segment 14 magnets M5, M6 are again used to light all yellow lamps. If the yellow lights are to come on before the red lamps N and S, say, are extinguished, a switch S1 is closed. W and 11 having lit the red lamps N and S, W and 12 now light all yellow lamps, energizing magnets M5 and M6 ; another circuit +ve, 18, 8, C8, 4, C4, switch S1, M3, 20, -ve is also made. This magnet M3 re-establishes the red lamps N and S so that the red and yellow overlap. A second switch S2 is used to overlap the yellow lights and the green lights N and S.

Patent GB-420157-A (GB)
Title: Improvements in or relating to a method of and apparatus for dispensing liquids
IPC: B67D1/14
Filed: 1933-05-22
Abstract: 420,157. Valves. CRAIG, D. A., Kembla Buildings, Margaret Street, Sydney, Australia, and WALSH, V. G., The Homestead, Stanmore Park, Middlesex. May 22, 1933, No. 14776. [Class 135] Relates to apparatus for dispensing liquids stored or supplied under pressure, more particularly aerated, carbonated or gas containing liquids such as alcoholic or non-alcoholic beverages, comprising inlet means for admitting liquid under pressure to a chamber, outlet means for discharging liquid from the chamber, vent means for relieving pressure in the chamber and common control means for the inlet and vent means. According to the invention, the common control means is so arranged that the vent means is opened to relieve the pressure after the opening of the inlet means and is closed before the inlet means is closed. In the construction shown, liquid is supplied under pressure to the dispensing chamber 1 through a pipe 17, ports 15, 11 in valve face 13 and an inlet passage in base 8, a baffle plate 54 serving to deflect the liquid and prevent undue turbulence. The base 8 also contains an outlet passage from chamber 1 which communicates via ducts 12, 16 with a discharge pipe or spout 18. A rotary valve 14 carried on a spindle 20 journalled in the base 8 is formed with a recess 19 adapted when the spindle 20 is rotated by handle 31 to bring the ports 15, 11 or 12, 16 into communication. The spindle 20 also carries a cam 27 on which rests a spring pressed rod 37 carrying at its upper end a snift valve 47, 48 which, when opened allows air to escape from the chamber 1 through passages 49 and aperture 50. The arrangement of the valves is such that with the handle 31 in the vertical position, Fig. 3, the recess 19 does not uncover any of the ports 11, 12, 15 or 16 and the snift valve is closed. On rotating the handle in the clockwise direction, Fig. 1, the recess 19 first places the ports 11, 15 into communication to admit liquid into chamber 1 whilst further -rotation of the handle in this direction then causes cam 27 to open the snift valve to a slight extent, the inlet valve remaining open. These operations are reversed when the handle is returned to its central position. On then rotating the handle in a counterclockwise direction, the cam 27 operates to open the snift valve and thereafter the ports 12, 16 are uncovered to establish communication between chamber 1 and discharge spout 18, the snift valve being fully opened. If desired, a second snift valve may be provided adapted to open instead of valve 47, 48, just as or just before the outlet valve is opened. A plurality of snift valves may also be provided adapted to be operated in succession to provide successively varying outlet openings for the escape of air and/or gas. Cleansing or other fluid may be introduced into the chamber when desired through a pipe 51 and cock 52.
