Title: Massaging apparatus
IPC: A61H15/00
Filed: 1976-02-16
Abstract: 1534911 Massaging apparatus MATSUSHITA ELECTRIC WORKS Ltd 16 Feb 1976 [26 Feb 1975] 05941/76 Heading A5R Massaging apparatus consists of a pair of rollers 21, 21a eccentrically mounted on and inclined with respect to a rotatable shaft 22, the drive between the rollers and shaft being provided by tongues 37, 37a of blocks 36, 36a threaded on screw portions 35, 35a of a shaft 34 which normally rotates with a shaft 22, disconnection of the drive between the shafts causing the blocks to move along the screw portions, and the tongues to move in slots 22a in shaft 22 to cause the rollers to move apart or approach. The rollers have hubs 38, 38a engaged by the blocks and which mount peripheral parts 26, 26a by ball races 24, 24a. Shields 32, 33, 33a prevent flesh being pinched between and by the rollers. The shaft 22 is mounted in bearings 42, 42a in frames 41, 41a upstanding from a base 40, a drive motor 13 and speed reducing gearing 14 being mounted on respective extensions 46, 47 from the base. The motor is resiliently mounted and drives through a belt 63 to a pulley at one end of a shaft, on the other end of which is a worm 59 meshing with a worm wheel 60 in a gear box 61. The worm wheel is mounted on shaft 22 and drive is transmitted to shaft 34 through a clutch 68 mounted on the gear box. The clutch has a first part 69 fixed to the shaft 22 and a second part 70 fixed to shaft 34, these parts normally being held in engagement to transmit the drive by a spring 34d. When it is required to shift the rollers along shaft 22 clutch part 70 is moved away from part 69 to stop drive to shaft 34 by a plate 71 pivoted by a push pull cable 81 against a spring 75. Faces of the plates 71 and clutch part 70 have respectively ridges and grooves which engage when the part 70 is withdrawn by the plate. When the rollers reach either end of their travel and the force of spring 75 is overcome, and forced rotation of shaft 34 causes clutch part 70 to rotate relative to the plate and the movement of the ridges over the grooves gives an audible warning. The push-pull cable is operated from a manual control having a rotatable upper disc 104. Rotation of this disc relative to a lower disc 103 in either direction closes one of a pair of microswitches 108, 108a to actuate the motor to rotate in one direction or the opposite direction respectively. Continued rotation of the upper disc will cause the cable to be actuated to disengage the clutch and cause the rollers to move towards each other or apart depending on the direction of rotation of the motor. The cable is pulled by a pin 100 being cammed towards a central shaft 102 by the edges of cut-outs in plates 101, 101'. A spring loaded ball engages notches in the outer edges of the plates to retain the upper disc in a set position. The extensions 46, 47 of the base and their associated motor and gearing are covered by end caps 95, 95a and the rollers are enclosed by a flexible cover 89 retained by clips 93, 93a.

Title: Improvements relating to screen wiper systems for motor vehicles
IPC: B60S1/08
Filed: 1968-02-08
Abstract: 1,143,920. Windscreen wipers. ROBERT BOSCH G.m.b.H. 8 Feb., 1968 [9 Feb., 1967], No. 6239/68. Heading A4F. [Also in Division G1]. A windscreen wiper motor is energized intermittently by a relay 18, Fig. 1, controlled by the output pulses of a multivibrator 30, 30<SP>1</SP>, the period between the pulses depending upon the state of motion of the vehicle. The measured variable may be engine speed determined by the frequency of ignition pulses from the ignition coil 2, by the frequency ripple or the mean value of the dynamo voltage, or by the position of the accelerator pedal; or it may be road speed. The ignition pulses are integrated at 8, 9, to give a direct voltage proportional to pulse frequency, this voltage controlling the state of conduction of a transistor 11. The transistor 11 is in a shunt path across a resistor 14 in the multivibrator timing circuit so that the multivibrator has one pulse rate when transistor is non-conducting, below a certain speed, and faster rate when transistor 11 conducts, above that speed. The length of the pulses determine how many sweeps the wiper makes per pulse, and this length is determined by the values of the other components of the multivibrator. In a variation of the circuit (Fig. 2, not shown) a pnp transistor (21) replaces the transistor (11) and the shunt circuit includes a potentiometer.

[Also in Division H3] The composition and disposition of metallic main electrodes 5, 6 and an insulator 2 in a spark gap triggered by a discharge along a surface of semi-conductor material are such that in operation any metal vaporized from the electrodes combines chemically with the insulating material to produce a material which is electrically substantially non-conductive, the insulator 2 forming part of a chamber which is filled with gas at such a low pressure that the device is operable at a point on the lefthand branch of the Paschen curve. The demountable device shown is filled with air at a pressure of 0.03 mm. Hg. and is held together by atmospheric pressure and optionally by clamping devices (not shown). A cathode 3 and anode 4 have tungsten-copper disc discharge surfaces 6 and 5. The insulator 2 is of steatite and has flanges 9 and 10 which protect sealing rings 7 and 8 from the discharge. The trigger device 12 has a central electrode connected to a pulse generator and having a tungsten-copper tip from which a discharge passes across an annular surface of zinccadmium oxide to a tungsten-copper ring. An eccentric exhaust pipe 11 communicates with a vacuum pump and a gas inlet and pressuremeasuring device. An insulator 15 lengthens the leakage path between a cathode connecting flange 13 and the anode 4. A modified device (Fig. 5, not shown) has a centrally disposed exhaust pipe 11 and two eccentrically disposed trigger devices 12. The metal of the main electrodes 5, 6 may be sintered and the main and trigger electrodes are preferably formed by an infiltrated composite metal comprising a skeleton of high melting-point metal, e.g. tungsten, rhenium or molybdenum, all the pores of which, or only those at the surface, are infiltrated by a second metal which is a good conductor of heat, e.g. copper or silver. Alternative materials for the insulator 2 are porcelain and eucryptite-containing ceramics. An alternative material for the semi-conductive trigger surface is silicon carbide.

[Also in Division G3] Regular time pulses are counted by a digital device up to the end of a pre-set interval, and a synchronous motor 16 operated in synchronism with the device, drives a pointer 17 over a scale 19 to indicate in analogue the progress of the interval. At the end of the interval the device re-sets itself along with the pointer to a datum position. A.C. voltage of say 60 c.p.s. is applied to terminal 1. Terminal 2 is the input of a digit counter which is connected in parallel with the motor 16. The digit counter is connected to a shaping circuit 3 feeding a six-nary circuit 4 supplying signals every 0À1 second to a first decimal circuit 5 in turn supplying signals every 1À0 second to a second decimal circuit 6. Rotary switches 7 and 8 connected to the output terminals of the decimal circuits are settable by knobs (9, 10), Fig. 2 (not shown), and the outputs go to an AND circuit 11 connected to a memory circuit 12 such as a flip-flop in circuit with an amplifier 13 and relay 14. If the device has been set to measure, e.g. 6À2 seconds, when the pointer indicates this, relay 14 cuts off the voltage and drives a re-set circuit 15. The pointer returns to zero. In order that the time remaining during the passage of the interval may be seen, in a modification a settable pointer (22), Fig. 4 (not shown), carried on a transparent cover (23) over the scale (19), is set to the desired interval.
