Abstract: 1303127 Internal shoe-drum brakes; adjusting for wear; indicating wear ROBERT BOSCH GmbH 2 April 1970 [2 April 1969] 15562/70 Heading F2E A brake such as an internal shoe drum brake which includes a brake shoe 15 movable by a threaded pin 12 screwed into a nut 9 in a cylinder bore 4 is automatically adjustable by virtue of a helical 45 degrees gearing connection 17, 18 between the nut 9 and a shaft 19, the shaft 19 carrying a ratchet wheel 24 having toothing 25 co-operating with a pawl 26 such that excessive movement of the brake shoe 15 in a braking operation will cause excessive rotational movement of gear 18 to thereby cause the pawl 26 to jump from one tooth to the next to adjust the axial position of nut 9 and hence adjust the brake as the brake is released. The nut 9 is moved in the cylinder bore 4 by the interaction of a cone-piece 2 at the end of a piston rod 1, and a roller 3 movable by the piston rod 1 on an oblique surface 8 of a plunger 7, the plunger 7 being held against rotation in the cylinder bore by co-operation of a key 6 and a key-way 6<SP>1</SP>. Automatic adjustment of the brake in this way will eventually bring a movable contact 29 on a stub 23 of the shaft 19 into cooperation with a fixed contact 30 to thereby complete a circuit 32 and light a lamp 31 to warn of substantial wear of the brake linings. The stub 23 also has a projecting tong 27 which permits of manual adjustment of the brake by a suitable tool. As shown in Fig. 3 the pawl 36 is pivotal on a lever 36<SP>1</SP> which is itself pivotally mounted and is biased towards a stop 37 by a spring 38; during initial release of the brake the pivoted lever 36<SP>1</SP> moves the pawl 36 away from the ratchet wheel 24 to relieve pressure on the gearing 17, 18, and the pawl is thereafter moved back towards the wheel 24. The arrangement is said to be applicable to disc brakes also.

Title: Apparatus for charging sample
IPC: B65G23/00
Filed: 1971-04-08
Abstract: 1307031 Feeding, discharging and driving endless conveyers MITSUBISHI CHEMICAL INDUSTRIES Ltd 8 April 1971 9085/71 Heading B8A [Also in Division B1] An endless conveyer 1 for trays 2 containing samples to be analysed is moved one step at a time by a solenoid 28 operating through a pawl 27 and ratchet-wheel 25. The arm 26 carrying the pawl co-operates with switches 30, 31 which control a solenoid-operated plunger 22, to locate the conveyer between steps, and a motor (not shown) which, through a wire 12, reciprocates a rod 3 laterally of the conveyer. The motor is controlled by switches 14-17 actuated by a projection of the rod 3 so as to move the tray 2 in line with it from the conveyer over a box 18 into a heating chamber (not shown) and then into analysing apparatus 20. The rod 3 is then retracted and, after analysis, is returned whereupon a hook 5 controlled by a solenoid 7 is lowered to engage the tray, a solenoid is energized to grip it, and the rod 3 is withdrawn. As the tray passes over the box 18 a hatch in its lid is electromagnetically opened and the tray drops into the box 18. As it drops, it actuates a switch which initiates a further cycle. In a modification, Figs. 7 and 8 (not shown), each tray has grooves engaged by inwardly turned flanges on the conveyer and after analysis of the sample, the tray is returned to the conveyer. Then during further operation of the conveyer, the tray is inverted and empties its contents into a suitably positioned box. The trays may be cleaned by an automatically operated brush or compressed-air nozzle.

Title: Constant speed drive
IPC: H02P25/02
Filed: 1970-09-07
Abstract: 1309326 Automatic speed control INSTRON Ltd 27 Aug 1971 [7 Sept 1970] 42699/70 Heading G3R The speed of a member such as the crosshead of a tensile testing machine is controlled by comparing the phase of reference pulses with the phase of signals derived from the rotor of a synchro coupled to the shaft of a driving motor. In the system shown, the stator windings of a synchro 13 receive 3-phase current from a square wave oscillator 10, a frequency divider 11, and a sinusoidal converter 12. The oscillator 10 also supplies one input of an arithmetic unit 15 which receives a second input from a constant frequency oscillator 20 through an adjustable frequency divider 23. The output from unit 15 is fed to a divider 16 having the same ratio as divider 11. A comparator 17 compares the phases of the signal from the divider 16 and a square wave derived from the synchro rotor  through a converter 18. In operation, when the motor is stationary and the unit 15 receives no input from the oscillator 20, the rotor of the synchro 13 is positioned so that the comparator output is zero. The rotor is shifted to this position by the comparator output, through a filter 19 and amplifiers 21, 22, shifting the drive motor 14, the shaft 28 of which is fixed with the synchro rotor. For driving the motor, the divider 23 is set to a required frequency so that pulses are added or subtracted by unit 15 to the signal from oscillator 10. Thus the phase of the signal to the comparator is advanced or retarded, and a signal is transmitted to the motor such that the synchro rotor is driven at the same speed and in the same phase as the reference pulses. The frequency of the oscillator 20 corresponds to the highest required speed of the motor 14, and the divider 23 may have a number of discrete settings corresponding to desired lower speeds.
