Title: Improvements in or relating to friction clutches
IPC: F16D7/00
Filed: 1958-01-31
Abstract: 860,604. Friction clutches; slip couplings. STIEBER, W. Jan. 31, 1958, No. 3346/58. Class 80 (2). A clutch or coupling transmitting torque from one member to another comprises a set of caged rollers skewed to the direction of rotation and engaged frictionally by the two members so that a part sliding and part rolling motion of the rollers with respect thereto takes place. The rollers may be of cylindrical, conical, barrel, &c. shape. In one form, rollers 2, Fig. 1, are held in a disc-like cage 1 and are engaged on opposite sides by driving and driven discs, the rollers being skewed to the direction of movement. As shown, the angle of skew α 1 , α 2 , &c. may be selected as required. In a modification, Fig. 3 (not shown), pairs of rollers lie in each aperture in the cage. In another form, a shaft coupling comprises a shaft 11, Fig. 4, having a cage disc 12 supporting interengaging pairs of skewed rollers 13 in frictional engagement with a disc 16 and a cup 14 fast on a shaft 15. If the force engaging the driving and driven members frictionally with the rollers of the device is controllable, transmission of movement therebetween can be prevented and the device can be used as a clutch. The rollers may be cooled by passing a liquid between them and the engaging friction surfaces, so that a device according to the invention can slip for long periods without over-heating.

Title: Improvements in or relating to pulse modulator circuits for magnetrons
IPC: H03C5/04
Filed: 1965-01-27
Abstract: 1,076,895. Pulse modulators. ALBISWERK ZURICH A.G. Jan. 27, 1965 [March 4, 1964], No. 3537/65. Heading H3R. A pulse modulator for a magnetron with means for blocking the circuit between pulses comprises a blocking oscillator T1 which is triggered by input pulses applied at terminal E and supplies positive square wave pulses which are applied via diode G2, capacitor C2 and transistor amplifier T2 to the gate electrode of a semi-conductor thyratron Thy which discharges a pulse forming network including inductors L1-L3 and capacitors C3-C5 through the primary of pulse transformer Tr2 having a secondary winding connected to the magnetron. On discharge of the network a second secondary of the pulse transformer provides an output pulse which charges C2 to a positive value in excess of any spurious pulses supplied by the blocking oscillator. The charge on capacitor C2 blocks the circuit for a period depending on the valve of R2, through which the capacitor discharges, and allows time for the thyratron to recover and for the pulse network to recharge.

Filed: 1921-02-01
Abstract: 176,613. Goodman, P., and Holmes, C. Feb. 1, 1921. Forging nuts; dies and punches. - Relates to the forging of hexagonal or other nuts by cutting off a length from a bar of a width equal to the side of the nut and forcing it into a die in which the hole is punched so that the blank is forced outwards to fill the die, and consists in using punches with bevelled ends to press the metal outwards to fill the die. In making an hexagonal nut, the bar 7 is placed over the die 1, and is sheared off and pressed into the die by an hexagonal tool 4, until it rests on an hexagonal snap tool 2. The bevelled punch 5 is then forced nearly through the blank and is withdrawn and the lower punch 6 pressed upwards to complete the hole. The snap tool 2 is then pressed on to the blank, and on the withdrawal of the tool 4 ejects the completed blank.

Title: Combined brake cylinders and slack adjusters
Inventor: SOBOL WOLDIMAR
IPC: B61H15/00
Filed: 1964-01-31
Abstract: 1,022,134. Fluid-pressure brakes; slack adjusters. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 15, 1964 [Jan. 31, 1964], No. 4197/64. Headings F2E and F2F. In a combined brake cylinder and slack adjuster the means connectible to the brake rigging is displaceable relatively to the axis of the piston to accommodate the rise and fall of that part of the rigging. The crosshead 35 is carried on a member 134 pivoted at 135 to one 8 of two relatively telescopic members of the adjuster. Two nuts 111, 112 on the threaded external surface of the member 8 have clutch faces 141, 142 engageable with faces 140, 121 on the member 9 attached to the piston 3, the nut 112 having a further face 117 engageable with the clutch face 118 of the sensing member 18. If the clearance in the brake linkage is normal then on activation of the piston by air pressure the sensing member will move leftwards with 8, 9 and abut the stop face 131 as the brake blocks engage the wheel. If the clearance is excessive further movement of member 9 engages faces 140, 141 so carrying 8 leftwards, the nut 112 spinning as slight clearance at the bearing 120 allows the faces 117, 118 to part and a gap opens up between the nuts, proportioned to the excessive clearance. On brake release the piston and member 9 move rightwards, the compressed spring 116 holding the sensing member 18 stationary together with nut 112, and member 8, the now-engaged faces 117, 118 holding the nut from rotation. The nut 111 now chases the face 140 carried on member 9 until that nut has moved to take up the clearance and abuts nut 112. Members 8 and 9 then withdraw together.  Manual resetting of the adjuster is provided by releasable means 152 connecting the crosshead 35 to member 134. Two other embodiments described (Figs. 1 and 2, not shown) are embodiments described in Specification 1,022,132.

Title: Improvements relating to anti-dazzle screens for automobiles
IPC: B60J3/02
Filed: 1929-02-03
Abstract: 325,682. Fitzpatrick, H. D., (Berkel, C. F. M. van). Feb. 8, 1929. Anti-dazzle screens.-In anti-dazzle screens or blinds for the rear windows of motor-cars of the kind controlled by means arranged in proximity to the driver's seat, the controlling means include a retaining device which, when manually released, allows a spring or other positive actuating device to pull the blind into its operative and/or inoperative position. In the construction shown in Fig. 1, the blind 9 is moved to an operative position covering the window 6 by means of a cord 12 attached at one end to the lower edge of the blind, and at the other end to a handle 16 which is depressed by the driver until it engages a locking recess 17a in a guide slot 17. When the handle 16 is disengaged from the recess the blind is returned to its non-operative position by an independent spring 18 or by a spring incorporated in the roller 10. In a modification the cord 12 pulls the blind to its uncovering position. In another modification, Figs. 4 and 5, the blind is operated in both directions, automatically, the cord 12 being connected to the rod 21 of a piston 23, which is slidable in a cylinder 22 enclosing a spring 25 and having ports 26, 27 at its ends. The port 26 is permanently connected to atmosphere, while the port 27 is connectible at the will of the driver, by operating a two-way valve 28, either to a pipe 29 leading to a source of suction, such as the induction pipe of the engine, or to a pipe 30 leading to atmosphere. The former connection causes the piston 23 to be drawn inwardly and the blind 9 to be pulled down, while the latter connection allows the springs 18, 25 to return the blind 9 and piston 23 to their normal positions.

Abstract: 607,983. Door locks. WILLIAMS, E. D. Feb. 11, 1946, No. 4234. [Class 44] The handle 3 of a door lock is disconnected from the locking mechanism in the " locked " condition so that it turns idly. In the " unlocked " condition it is reconnected by a radially slidable pin 18 operated by a key lock 17 in the handle. The handle is supported in a sleeve 12 in which it is rotatably retained by parts 15a which are suitably weakened by transverse saw-cuts so that they may be deformed on assembly to engage in an annular groove 15 in the reduced shank 14 of the handle. The sleeve 12 is connected by a square section rod 9 to the lock mechanism 6 and in the unlocked condition is connected to the handle by the sliding pin 18 which engages a recess 19 in the sleeve. A spring-loaded pin or ball 20 is adapted to engage a hole 21 in the sleeve to indicate the position in which the pin 18 may be shot. Spring-pressed balls 22 in the rose engage a flange 13 to take up play between the rose 11 and the handle 3. An existing lock of the type in which the spindle 9 is integral with the handle 3 may be converted to this form by modification of the handle stem 14 or rose 11 to accommodate a sleeve such as 12 and by altering the slidable pin so that it engages the sleeve 12 only.
