Title: Centrifugal fluid-powder clutch with radial grooves
IPC: F16H61/02
Filed: 1968-01-19
Abstract: A centrifugal clutch A, which may be included in a brake device, comprising a rotor 9 and a casing 1, and in which torque is transmitted therebetween by granulated material, e.g. stainless steel, or small spheres, has substantially radial grooves formed in the opposed faces of the rotor and casing, the grooves on the rotor being of different peripheral width to those on the casing, to cause circulation of the granular material between the grooves and to allow prolonged slip without a destructive rise in temperature of the rotor, the heat being dissipated from the casing, which may be formed with cooling fins 1a The grooves have round bases and form a continuous series, adjacent grooves being connected by sharp, or rounded, radial edges, the degree of sharpness and the depth of the grooves, together with the number of grooves, the inclination of the opposed grooves towards each other, and the distance between the rotor and casing, determining the degree of slip allowed. The casing or the rotor may form the clutch input member. By releasably and selectively connecting one of the clutch members to a stationary framework, the clutch may act as a brake, the allowed slipping of the clutch braking the other member. As shown, two clutches A, B, are provided in series, e.g. in a vehicle two-speed transmission, with separate output shafts 13, 37 carrying pinions 17, 41 respectively, meshing pinions 18, 42 on a common output shaft 19. The pinion 17 is mounted on shaft 13 by a one-way jamming roller clutch 16. On rotating input shaft 5, the casing 1 rotates to rotate rotor 9 and shaft 13 driving shaft 19 through pinions 17, 18. On reaching a predetermined speed, centrifugal masses 21 rotating with shaft 13, engage casing 23 of clutch B to rotate the casing and rotor 26, shaft 37 then driving output shaft 19 through pinions 41, 42, pinion 17 overrunning. The grooves in the rotor and casing of clutch B are shallower than in clutch A, and are connected by rounder edges to allow greater slip, and, should the load become excessive, to allow clutch A to again take up the drive. The casing halves of clutch B are adjustable towards each other to vary the slip either by centrifugal masses (32), Fig. 4 (not shown), coacting on ramps (33) on lugs (34) on the casing halves, or by a jack (35), Fig. 6 (not shown), controlled in accordance with the load, (not further described). Again, Fig. 7 (not shown), the clutches A, B are formed in a single casing having a dividing partition, their output shafts driving a suitable gear-box. In Fig. 8 (not shown), the clutch B is formed inside the clutch A, the casing of clutch B forming the rotor of clutch A.

Abstract: A hair curler which automatically winds a lock of hair upon a spring-driven rotating roller on release of a manually operated clutch, comprises a hollow drum 1 rotatably mounted on a spindle consisting of telescopically engaged inner and outer members 4 and 5, that are urged apart by a compression spring 13. The spindle members are preferably non-rotatable relative to each other and have end portions 7 and 14 projecting through cylindrical apertures in end caps 2 and 3, these end caps being rigidly secured to the drum. The spindle end portion 14 has a ridged frusto-conical clutch surface 15 engaging with a corresponding ridged inner face of the aperture in end cap 3. A coiled torsion spring 18 surrounding the spindle, has its one end attached thereto at a point adjacent to the clutch head, and its other end 181 secured to the inside of the drum at 11. A hair clamping jaw 21, fitting into a corresponding recess 20 in the outer face of the drum, is hinged to the drum at 22 and has a fastening stud 27 which enters an aperture 28 to engage with a clasp 29 on the inner face of the drum. Along its opening edge the jaw has a strip of resilient friction material which mates with grooves 26 when the jaw is closed. An L-shaped rod 8 is non-rotatably secured by its shorter arm in the spindle end portion 7, with its longer arm extended over and along the drum. In use, the torsion spring 16 is initially stressed, a lock of hair is inserted under rod 8 and clamped against the drum face by closing on it the jaw 21. The spindle ends 7 and 14 are then manually pressed towards each other against the action of the compression spring 13, whereupon the cooperating clutch faces at 15 are disengaged and the stressed torsion spring rotates the drum and winds the hair-lock thereon. The hair is removed by again disengaging the clutch and pulling on the hair curler, when the hair unwinds and re-stresses the torsion spring for another curling operation. Several alternative types of hair locking jaw are described also the coiled form of torsion spring may be replaced by a helical clockwork type spring.

Title: Electrostatic precipitator electrode cleaning system
IPC: B03C3/74
Filed: 1975-11-25
Abstract: Electrically-activated shaking devices are arranged in modules to shake the electrodes of an electrostatic precipitator, each module corresponding to a different section of the precipitator. An operating system for the shaking devices includes a main distributor circuit that sends electrical signals to individual control circuits at each of the modules in sequence and at a relatively fast rate. Each control circuit has an adjustable timer that independently generates pulses at a relatively slow rate and a synchronizing circuit that generates an output signal only if it receives a signal from the timer followed by a signal from the main distributor. Each control circuit further includes a secondary distributor circuit that operates in response to the synchronizing circuit to activate the shaking devices in the associated module sequentially. An inhibit device operated by the synchronizing circuit prevents more than a single shaker from being activated at a time.

Title: Liquid medicine dispensers with dose mechanisms for oral and injection therapy
Inventor: WAGNER WOLFGANG DR MED
IPC: A61M5/42
Filed: 1975-12-29
Abstract: It is intended, that the invention facilitate medicine therapy by providing the medicine supply containers directly with an adjustable dose mechanism, for which a medicine propulsion through a membrane, which is under pressure, is especially intended. For injection treatment, the possibility of a direct dubcutaneous injection through a cannula placed on a dose mechanism is created, to the extent that measures are taken to maintain sterility by special sealing devices (disinfection, suction, band movement etc). The filling of the syringes from a large supply in stationary injection use can generally be facilitated through the limitation of the movement of the syringe piston by dosage stops the projection of sterility can be achieved with greater additions and costs (rinsing systeme etc). Finally, for oral use, rinsing-fluid and medicine containers are at least functionally connected with one another, so that counting of drops and rinsing glass are dispensed with. The smallest unit, the pressurized gas ampule, allows the use of different cannulas for individual doses.
