Title: Digital data storage apparatus
IPC: G06F3/06
Filed: 1975-10-22
Abstract: 1497680 Data storage systems INTERNATIONAL COMPUTERS Ltd 22 Oct 1975 [29 Oct 1974] 43290/75 Heading G4A A plurality of data blocks are serially recorded on each of a plurality of tracks of a recording medium 11, N read heads enter data from respective tracks into corresponding buffers 13 in parallel, and the buffers 13 are read out sequentially, one block from each buffer, onto an output path 17 at a data rate at least N times the average rate at which data is read from any individual track. By recording successive blocks of a sequence on different tracks, e.g. on the same cylinder of a disc file, a higher read-out rate is obtained. The blocks are preferably staggered from track to track. A sequencer 14 detects an identifier (ID) associated with each block, only one ID at a time appearing on channels CH owing to the blocks being staggered. Each ID contains cylinder, channel and block numbers for the associated data block, the channel number being decoded by sequencer 14 to control write-in to the appropriate buffer 13. Channel and block counters in sequencer 14 predict these numbers for the next block to be read and are incremented if a matching comparison is obtained with the next ID. Each buffer 13 includes a 4-bit serial to parallel converter feeding a shift register which has four bits per stage and is clocked in at “ of the channel data rate. Arrival of the end of the preamble, which precedes each data block, at the end of the shift register causes generation of a buffer full signal which inhibits further clocking in of the shift register. When the buffer is selected for read out by a signal CHR from output control 15 the shift register is read out by a high speed highway clock onto a 4-bit data highway 17. A counter in output control 15 produces a CHECK signal when check bits which accompany each data block are on highway 17, and this initiates a comparison between the check bits on highway 17 and check bits derived from the data by a check circuit 51. Further channel and block number counters in control 15 are preset when the first ID is read, the channel number being decoded to produce channel read-out select signals CHR commencing with the first channel on which a block was read.

Abstract: 1420859 Spot-type disc brakes AKEBONO BRAKE INDUSTRY CO Ltd 18 Sept 1973 [19 Sept 1972 25 June 1973] 43664/73 Heading F2E A spot-type disc brake comprises a fixed support having two legs each with friction-pad guiding-parts provided therein and each located on one side of a disc, a head portion of the support interconnecting the two legs and straddling the disc, and a caliper head which interconnects an acting part and a reacting part of a caliper assembly and is provided with a hollow therein, the head portion of the fixed support being situated within the hollow and the caliper assembly being supported by the head portion of the fixed support so as to be guided for movement parallel to the axis of the disc. As shown in Figs. 1, 2, each leg 3 or 4 of a fixed support 1 has a circular hole 25 or 26 to guide an assembly consisting of back plate 8 or 9 and friction pad bar 7; the legs are joined by a head 2 located by a plate spring 24 in a hollow 11a in a caliper head 11. A guide pin 21 is screwed into the fixed-support head 2, and caliper 10 slides on this when fluid under pressure is introduced to chamber 16. In Fig. 3 the caliper guide pin 124 is located between a blind hole 127 in the caliper 112 and a snap ring 134 fitted across a hole 129 at the other end of the caliper, so the pin must slide with the caliper, and extends for that purpose through a hole 125 in fixed-support head 102. The rest position of the caliper and guide pin gradually moves to the right as the friction pads wear away, resulting in compression of a spring 132 so that the right hand end of a flexible sealing cover 130 is forced more tightly into a notch 126. A check plate 138 fitted against a shoulder 137 of a hole 136 in reacting part 116 of the caliper is secured by a bolt 139 to back plate 109 of outer friction pad 108. The outer pad is prevented thereby from turning round, and the caliper is prevented from vibrating on guide pin 124.
