Title: Electrically driven vibration and rolling massage apparatus
IPC: A61H15/00
Filed: 1931-03-20
Abstract: 370,629. Massage apparatus. SCHNEIDINGER, 1'11., 180, Lichtenfeldgasse, Mondsee, Austria. March 20, 1931, No. 8634. Convention date, March 22, 1930. [Class 81 (ii).] Apparatus for vibratory and rolling massage comprising a beater with a magnetic hammer break system, operated by direct or alternating current, said beater acting indirectly, i.e. through the intermediary of the massage rollers,. upon the skin, is characterized by the provision between the beater i, p, which is fitted with an adjustable contact spring m for regulating the vibrations when direct current is used, and the element transmitting the vibrations to the skin, and attached to either, of a spring q or l<1> so chosen that when alternating current is used the magnetic hammer break is in synchronism with the oscillations of the current. Two massage wheels d are mounted in a U-shaped frame c to which is secured the vibrator b comprising a magnet frame e, carrying iron cores f wound with coils g, h, and an armature i, preferably of soft iron, having a contact spring m secured thereto and separated by an insulating layer n. The armature extends through the frame c and has a head p, transmitting its vibrations through a spring q with a striker head ql fixed to the armature and resting on the head r of a sleeve g<1> provided on the axle s of the wheels d. The contact spring m may be a blade, spiral, or helical spring, in which latter case it may be sunk in the armature and exchangeable. A contact screw u contacting with the spring m is adjustable within a bracket v and secured by a spring x. When direct current is used, the periodicity of the vibrations can be varied by adjusting the spring m. With alternating current, the vibrations of the hammer adapt themselves to the frequency of the current, so that adjustment of the spring m only regulates the hardness and not the frequency of the massage. The current supply leads entering through an opening in the end of the casing a are supported by a wire c<1> and are connected to terminals k, l. The coil h mav be connected to one terminal k and to the contact spring m, the coil g to the terminal l and the screw u or bracket v. The massage wheels d are pressed inwardly by springs f<1> on the sleeve g<1>. The wheels have rubber tyres i<1> with depressions h<1>. In Fig. 6, an impact core k<1>, resiliently mounted in the bent axle s on a spiral spring l<1> and movable therein, replaces the transmission spring q. The massage wheels are supported by circular pressed steel springs. A modified form of contact screw u is shown in Fig. 7, in which a locking spring o<1> is provided with a projection p<1> engaging teeth q<1> beneath the head of the screw.

Filed: 1943-05-31
Abstract: 566,584. Electric tests. BRITISH THOMSON-HOUSTON CO., Ltd. May 31, 1943, No. 8695. Convention date, May 30, 1942. [Class 37] [Also in Group XXXVII] In a protective arrangement for star-connected devices with isolated neutral, such as power-factor improvement condensers 16, in which a failure in one phase produces relativelylow fault currents (which are too low to operate fuses rated to deal with inrush circuit-closing currents), whereas simultaneous failures in two phases cause a short-circuit current in two of the lines, separate means are provided to deal with the two types of fault, the short-circuits being cleared by quick-acting, current-limiting fuses 29 preferably constructed as described in Specification 528,629, whereas the low-current faults are cleared by means dependent on displacement of neutral-point potential. The neutral point 17 of the bank is connected to an artificial system-neutral 20 derived from starconnected impedances or, as shown, transformer-primary 19, the open-delta connected secondary 21 of which supplies a trip relay 25. Where one breaker 15 controls two or more banks, the relays 25 have indicators 28 which enable the operator to identify the faulty bank and isolate it at fuses 29, and to restore the sound one to servier. When two phases of a bank fail, one fuse 29 blows it over and the fault is subsequently cleared by the operation of the low-fault protection device.

Filed: 1945-04-09
Abstract: 584,544. Brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and PARNELL, F. G. April 9, 1945, No. 8739. [Class 103 (i)] In a drum brake of the kind in which at least one of a pair of shoes is mounted for limited circumferential movement on a carrier or lever so that the shoe always acts as a leading shoe, the carrier being operated at one end by the shoe expander and engaging at the other end an abutment that 'is adjustable to take up wear of the friction lining, the arrangement is such that the carrier and shoe move as one during the adjustment. As shown, webs 40, 41 of the shoe 11 embrace the carrier or lever 36 upon which the arcuate part of the shoe bears through rollers or an anti-friction strip 42. The carrier and shoe 10 engage at the lower ends a fixed abutment 15 and at their upper ends plungers 16, 17 upon the inclined inner ends of which bear segmental rollers 21 pivoted on a strut 23 operable as by fluid pressure to apply the brake. If, when the brake is applied the drum is rotating counterclockwise the shoe 11 anchors by engagement of the webs 40, 41 with surfaces 46 on the casing 20 of the expander and if the drum rotation is clockwise, pins 43 engage the ends of slots 44 in the carrier as shown so that the shoe anchors through the carrier on the abutment 15. This abutment comprises screwed pins 27, 28 the ends of which receive the ends of the shoe 10 and carrier 36 and which are movable axially by turning sleeve 26 within the fixed housing 25. The sleeve is toothed at 32, 33 for engagement of an operating tool and a detent 34. The surfaces 46, 37 on the casing 20 and on the plunger 17 that are engaged by the ends of the webs 40, 41 and the carrier are flat and when the plunger is in the off position are in the same plane and as the ends of the webs and the carrier are curved to a common radius, the axes of curvature of these ends are then coincident. During adjustment by the abutment 15 the shoe 11 and the carrier thus rock without relative movement on their upper curved ends. The shoe 10 may be mounted similarly to the shoe 11.
