Title: Brake actuating cylinder with autoadjuster
IPC: F16D65/14
Filed: 1975-12-18
Abstract: 1513740 Wear adjusting in hydraulic actuators AUTOMOTIVE PRODUCTS LTD 18 Dec 1975 [23 Dec 1974] 55461/74 Heading F2E A strut which limits the return movement of a hydraulic piston comprises a screw and nut one of which has helical ratchet teeth engaged by a spring biassed pawl. As shown, the screw 43 is rotationally fixed relative to piston 41 and the nut 44, formed with helical ratchet teeth 47, is axially movably within a bore in a second piston 39, the pistons being arranged to act on respective shoes of a drum brake. A radially movable cylindrical pawl 48 is biassed into engagement with the teeth by a spring ring 53 which is self-tightening in one direction of rotation. In operation, the screw and nut move with piston 41 during brake application, rotation of the nut being restrained by a second spring ring 53 which causes a drop in the screw threads by frictionally engaging the piston bore. If movement is excessive the pawl will ratchet over the teeth and, on brake release, turn the nut until it abuts a step in the bore of piston 39 so lengthening the strut by a fraction of the excess brake clearance. In a modification (Fig. 5 not shown) the ratchet teeth are formed over the screw and the resistance to rotation of screw and nut during brake application is effected by the provision of self-locking threads. In either embodiment, the ratchet teeth can be reversed so that adjustment occurs as the pistons separate.

Title: Electronic musical instrument

Filed: 1972-12-28
Abstract: 1420085 Electrophonic musical instruments NIPPON GAKKI SEIZO KK 28 Dec 1972 [30 Dec 1971 (3) 22 Feb 1972 (2) 26 Feb 1972 (3)] 59821/72 Heading G5J In an electrophonic musical instrument instantaneous amplitude samples of a waveform are stored in analog form and means are provided to readout the samples simultaneously at a plurality of selectable rates and produce therefrom a plurality of musical tones. As described the instrument comprises upper and lower keyboards 1b. The operation of a key is detected by a key address code generator la which generates a sequence of binary codes corresponding to each key. The code has eight bits, four to determine the note, three to determine the octave and one to indicate upper or lower keyboard. The keyboard passes a signal to common logic circuit 3 when the code of any actuated key is generated. The logic circuit for achieving this is described, Fig. 2(a) (not shown). On the assumption that no more than ten notes will be required simultaneously, ten signal channels CN are provided. Common logic circuit on receiving a signal from the keyboard checks that there is not already a channel dealing with that key and if not writes the key address code into the memory 2 of a vacant channel. Memory 2 controls a counter 5 to read a wave shape out of either memory 11 or 12. The note bits of the code select one of twelve tone clocks respectively sixteen times the frequencies of the notes of the top octave; the octave bits control where in counter 5 the clock is connected and the upper/lower bit selects memory 11 or 12. In an alternative embodiment, Fig. 4 (not shown), there are separate tone clocks for all notes of all octaves. Attack and decay envelope samples are stored in the first sixteen and last forty-eight address of a memory 14. An envelope counter 6 started when a new key is depressed counts up to 16 reading out the attack waveform which is applied as a scaling factor to the inputs 11a, 12a of the memories 11, 12. Counter 6 then stops until restarted by release of the key to read out the decay envelope to memories 11, 12. The contents of counter 6 is also held during the decay in a truncate counter 7. If a fresh key is depressed while all channels are in use, the common logic 3 checks which channel has progressed furthest with a decay by feeding rapid pulses to all the truncate counters and seeing which overflows first. The overflow signal clears that channel and the new key address is written into its memory 2. If a key is depressed while the corresponding note is decaying, its channel is cleared and the attack starts afresh. The channels are connected in sequence to the memories 11, 12, 14 by a multiplexing counter 8.  The memories preferably comprise resistors connected as voltage dividers with the stored sample corresponding to the tapping point, Fig. 5 (not shown).
