Title: Apparatus for storing digital data on a moving magnetic medium
Inventor: KOSTEN LEENDERT
IPC: G11B20/16
Filed: 1953-12-15
Abstract: 780,030. Electric digital-data-storage apparatus. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Dec. 15, 1953 [Dec. 29, 1952], No. 34940/53. Class 106 (1). A magnetic recording system using a moving magnetic storage medium, the system being of the kind in which any given storage cell is read by a read/write head as the head passes over the first half of the cell and in which the said given storage cell is written into by a pulse applied to the head only while the head is passing over the second half of the cell, is characterized in that signals from the head are modulated on a high-frequency carrier, amplified and then detected, the frequency of the carrier being high with respect to the frequency of reading successive cells. Clock pulses ki from a drum MTR, Fig. 3, are delayed by a delay IV to produce two sets of pulses pi and pi2-each pulse pi1 occurring during the second half of a cell and each pulse pi2 during the first half of a cell-which control write and read gates P1 and P2 respectively. The time of duration of the two pulses pi2 and pi1 that occur in each cell is shown in Fig. 2, by the two cross-hatched portions respectively ; Figs. 2 (a) and 2 (d) showing the currents that flow in the head for writing a one and a zero respectively, Figs. 2 (b) and 2 (e) showing the magnetic flow produced in a cell as a result of these currents, and Figs. 2 (c) and 2 (f) showing the signals that would be induced in the head by a one and zero respectively if no writing occurred in the second half of the cell. All data passes to the drum from a processing device RO, via the gate P1 and all data from the drum passes via a modulator-amplifier-detector unit AV and then via the gate P2 to the processing device. The gate P1 is constituted by a double triode PI, Fig. 4, having its two grids controlled by pulses pi1. To record a " one " a positive pulse is applied from the processing device RO to the left-hand grid, causing, when a positive pi1 pulse is present, current to flow through the head via resistor Rko to earth. When a signal is induced in the head it is superimposed on a high-frequency carrier from an oscillator 0 by a ring modulator M, amplified, detected by a device D and passed to the gate P2 (not shown in Fig. 4). Any write signal also modulates the carrier, but this is of no consequence because gate P2 is then closed, and the drawback that the amplifier will be blocked by the large write signal is overcome by making the amplifier responsive to high-frequencies only, since then, the amplifier can be designed to recover from the blocking within a few cycles of the highfrequency current, i.e. well before the amplifier needs to amplify a read signal. Reference has been directed by the Comptroller to Specification 693,157, [Group XXXIX].

Abstract: 376,638. Screwing-up bolts and screws. CONNELL, E. L., 513, Greenbrier Road, Towson, Maryland, U.S.A. Dec. 18, 1931, No. 35140. [Class 83 (iii).] In a portable power-driven screw-driver the tool is driven through a friction clutch which may be adjusted to slip at a predetermined load and may also be given a further temporary adjustment to slip at a higher load, the second adjustment being such as not to affect the original adjustment when released. The machine comprises a casing 1 containing a driving motor 45 and reduction gearing 7 for rotating the tool spindle 22 which is slidable and rotatable in a bush 23 keyed to the casing at 24. The tool 34 is secured in the spindle by a ball 33 and is slidable within a guide sleeve or finder 36 which engages the head of the screw &c. being driven, and is yielding pressed forwards by a spring 38. Clutch parts 20, 21 on the driving gear 12 and spindle 22 are normally disengaged by a spring 30 but are engaged when the tool encounters the work. The initial pinion 60 of the gear train 7 is carried by ball bearings 55, 67 slidable in the casing and is connected with a ventilating fan 48, keyed to the motor shaft, through friction discs 73, 75 on the pinion shaft 65 and fan respectively. A leather &c. disc 77 may be interposed between the friction discs, the latter being pressed together by a spring 80 acting on the bearing 55 through a disc 95. The other end of the spring 80 abuts on a flange 84 on an adjusting screw 85 rotatable in a nut 90 which is slidable but not rotatable within a polygonal opening in the casing. Rotation of the screw 85 sets the clutch 73, 75 to drive home metal screws or the majority of a number of wood screws, but should any of the latter encounter an unduly hard piece of wood the pressure on the clutch may be increased by pushing the screw 85 inwards together with its nut 90, release of the screw then restoring the original pressure to the clutch. A flange 93 on the nut 90 limits its outward movement.

Abstract: 1,248,156. Digital computers. BURROUGHS CORP. 15 July, 1969 [19 July, 1968], No. 35465/69. Heading G4A. A data processor includes a plurality of operator family controllers A to X, each for forming control signals from one family of program operators only (each operator being in one family only), hardware resources 200 for manipulating data in response to the control signals and a control unit 300 for co-ordinating the operations of the controllers A to X. The controllers are preferably physically separated from one another and each comprises an operator register and decoder, a sequence counter and decoder and a control network. Each controller may initiate twenty different operators, for example add, integerize, index &c. The hardware 200 comprises parallel adders, magnetic core memories, shift networks, transfer busses, stack adjusting apparatus and like circuitry, and is fed with instructions from the controllers A to X by a bus 400 which has one line for each operator signal. The control unit 300 fetches program instructions from the hardware 200, selects the appropriate controller for each operator and instructs the controllers A to X by a bus 500. When a controller has completed an operator function it signals completion on a bus 600 (SECL) to the unit 300 which sends a strobe signal via bus 800 and causes the appropriate controller to receive its next appropriate operator signal. The bus 500 connects all the controllers so that a first controller carrying out a first operation can instruct another controller to complete an operation which forms part of the first operation by means of the bus 700 which suppresses the unit 300 for that operation.

Title: Method and apparatus for writing and reading binary encoded data on and from a moving storage medium
IPC: G11B20/16
Filed: 1974-08-13
Abstract: 1482136 Encoding and decoding BURROUGHS CORP 13 Aug 1974 [12 Sept 1973] 35599/74 Heading G4C In a system for writing and reading selfclocking binary encoded data on or from a moving storage medium 11, e.g. a magnetic disc, non-self-clocking binary data is encoded into self-clocking binary data by use of a write clock signal responsive to the speed of the storage medium 11, and the self-clocking binary data is decoded using a read clock signal recovered from the read-out self-clocking binary data to generate asymmetrical data windows. Writing.- Non-return-to-zero (NRZ) non- self-clocking binary data received on a line 37 is encoded into modified-frequency-modulated (MFM) self-clocking binary data by an encode circuit 25, the output 47 of which feeds read/ write electronics 21 coupled to a read/write head 13. Index pulses on a channel 19 are detected by a head 15 which has its output connected directly to a write clock and sector mark generator 27, the output of head 15 also passing indirectly to generator 27 via a speed detector 23 which produces an output when the storage medium 11 reaches a predetermined percentage of its terminal speed. Reading.- MFM binary encoded data signals read from the storage medium 11 pass from read/write electronics 21 to a read clock recovery circuit 31, which also receives inputs from generator 27 and from a clock-triggered timer 29. Timer 29 produces an output signal a predetermined length of time after the first read clock pulse produced, and thereafter is disabled until the next read command. The read clock pulses pass to an asymmetrical window generator 33 and thence to one input of a decode circuit 35, the other input of which receives the MFM data. The output of decode circuit 35 is in the desired NRZ form. Detailed circuitry of the encode circuit 25 is given in Fig. 2 (not shown). Reference has been directed by the Comptroller to Specification 1,165,658.

Abstract: 946,118. Film threading devices. H. ERNST, [trading as ED LIESEGANG]. Oct. 24, 1960 [Nov. 5, 1959], No. 36356/60. Heading G2E. Kinematographic apparatus includes, on either side of the film-channel, a feed roller and a co-operating pressing shoe and, between the feed roller and the film channel, an open-sided guiding and loop-forming member which normally lies remote from the film path but which can be brought into the film path for threading of the film. As shown in Figs. 1 and 2 the guiding and loop forming members 6 and 7 are carried respectively on pins 8, 8<SP>1</SP> and 9, 9<SP>1</SP> extending through a base plate 1. Normally, the members 6 and 7 lie against the base plate 1, out of the film path defined by feed rollers 4, 5 and the film gate 3, due to the thrust of compression springs 11 between the other side of the base plate and a cross-piece 10 connecting the pins. Initial depression of key 16 pushes the cross-piece 10 against the plate 1 so that the film guiding parts 6 and 7 enter the film path against the loading of springs 11. This will be prevented by projections 18, 19 on the filmpressing shoes 4<SP>1</SP>, 5<SP>1</SP> if the latter are not in proper pressing engagement with their respective feed rollers, as indicated by the broken lines in Fig. 1. Further depression of the key 16, against the leaf spring 13, causes lever 14 to close the switch 17 and thereby energize a driving motor (not shown) to drive the feed rollers 4 and 5. On introducing the leading end of a film between the roller 4 and shoe 4<SP>1</SP> the film will be automatically threaded. Partial release of key 16 disconnects the drive for the feed rollers and then by fully releasing the key the parts 6 and 7 are withdrawn from the film path by the springs 11.
