Dec. 19, 1934, No. 36445. [Class 132 (ii)] In a stringing-machine, the strings are tensioned by the operator compressing a spring, and the compression of the spring is arrested when the predetermined tension is reached, by a member engaging a cam adjustable according to the tension required for the different strings. In the embodiment shown, a racket frame b is clamped at b<1> to an arm b<2> rotatable about an axis b<3>, and held in any desired angular position by a pawl b<4>, operated by a pedal b<8> through links b<7>, engaging in a pinion b<5> on the axis b<3>. A string x after being strung through the racket is passed around and between gripping blocks c, c, c<1>, Fig. 7. The blocks c are rigid with a frame c<3> and the block c<1> slidable therein, the block c<3> being secured to a block d slidable in a casing a<1> secured to the machine base a. A screwed spindle e passes through a clearance hole in a flange d<1> on block d and is threaded into a bar f longitudinally slidable in casing a<1> on guides f<2> and a compression spring g is disposed between the bar f and flange d <1>. To tension the string x, the operator rotates the handle e<1> of spindle e and the bar f moving along the thread e, compresses the spring g against the flange d<1> in opposition to the string tension. When the predetermined tension is reached, a cam h rigid with the bar f engages a roller j<2> on a link j pivoted to the block d, the link j through a linkage j<1> moving a pawl j<3> into engagement with a ratchet wheel j<4> on the spindle e, automatically to stop further rotation thereof. To provide for different string tensions required for various rackets, the cam h comprises a truncated cone longitudinally adjustable on a spindle h<1> mounted in arms f of the bar f, the string tension corresponding to the various axial positions of cam h being read off on a scale i carried by spindle h<1>. A screw h<3> locks the cam to the spindle h<1>. To provide for the different tensions in the string groups of the racket the cam cone h has flattened or otherwise shaped portions h<6> which are brought into operative position by rotating the cam through a hand wheel h<5> on its spindle the cam being locked in selective angular positions by a spring pawl k coacting with a star wheel on spindle h<1>. The spindle e is released for subsequent operations by backward rotation. According to the Provisional Specification the string gripping device is carried by a nut threaded on the screwed spindle (e).

Abstract: 1,104,792. Fluid-pressure brakes. GIRLING Ltd. 14 Sept., 1964 [17 Sept., 1963], No. 36464/63. Heading F2F. A vehicle hydraulic braking system incorporates means sensitive to angular velocity differences between a front and rear wheel to control pressure differentials on opposite sides of a piston or diaphragm 31, the movement in one direction of which actuates a valve 17 to cut off communication between a master cylinder and brake cylinder or cylinders and increases the line volume between said valve and brake cylinder or cylinders. In the embodiment shown, fluid from master cylinder 10 is fed through a line 11 to a control unit, actuated by means sensitive to front and rear wheel angular velocity differences, and then through lines 12 and 14 to rear and front brake cylinders 13 and 15 respectively. The control unit is formed by identical left and right-hand units each feeding front and rear wheels sets of brakes respectively, each unit comprising a bore 18, a fluid inlet 16 controlled by a tipping valve 17, an outlet 19, and a piston-rod 22 having a piston 23 slidably mounted in the bore, said piston-rod in the left-hand unit, for example being normally urged to the right by a spring 24 to abut a collar 21 on said rod to hold valve 17 open. The right-hand end of the rod abuts a diaphragm 31 subdividing a chamber 27, both parts of the chamber having connections 33 and 32 to a source of vacuum 30 and to atmosphere, respectively, the latter being selectively controlled through valves operated by means sensitive to angular velocity difference of front and rear wheels. In operation, an angular velocity difference being sensed during braking, air is admitted to the right one of ports 32 depending on relative wheel speed differences urging the diaphragm either to the left or right, one or other of the valves 17 to close and simultaneously increasing the fluid volume of bore 18 to relieve the brake cylinder pressure, outlets controlled by valve means sensitive to angular velocity differences. Means sensitive to angular velocity differences may comprise flexible drives 34, 35 from front and rear wheels operating selectively actuable valves (40) through gearing (36), Figs. 3 and 4 (not shown), said valves controlling air supply to the chamber 27. In an alternative arrangement, Figs. 5, 6, 7 and 8 (not shown), the speed sensitive means comprises two paddle wheels (42) driven in housings (41) containing hydraulic fluid by two bevel gears associated with a front and rear wheels respectively. Fluid from each housing is led to the opposite ends of the control unit chamber to actuate a diaphragm or piston therein when the angular velocity of the front and rear wheels differ.
