Title: Improvements in or relating to format control for data recording
IPC: G11B20/12
Filed: 1962-11-27
Abstract: 951,040. Data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 27, 1962 [Dec. 26, 1961], No. 44812/62. Heading G4C. In a random-access disc store, with each set of storage discs 13,14... is associated a master disc 12 which controls the layout of the data on the storage discs. A typical track of disc 12 is shown in Fig. 2, line (b). There is a permanent index mark recorded elsewhere on the disc and sensed by transducer 12m. Immediately following the radius on which the index mark lies is a gap of 16 bits and after a set of 24 bits an eight bit gap called a short gap. The next 56 bits are used to clock an address on to a storage disc. Then, after three short gaps, are the clock bits for the main portion. These are succeeded by a long gap of 16 bits. This pattern is recorded by the circuitry shown at the top of Fig. 1 and can be considered as permanent. In the read circuitry of transducer 12h is a short gap sensor 38 which operates after a gap of three bits and a long gap sensor which operates after a gap of twelve bits. Sensor 38 steps a counter 41 and sensor 39 resets it. If it is desired to write an address, input gate 48 is open between the marking of the first and second output lines of counter 41. To read an address gate 61 is open from the sensing of the long gap until the user equipment senses that the address has finished. To write data, gate 56 is open between the sensing of the fourth short gap and the beginning of the last long gap which is sensed by sensor 38, sensor 39 then operating to reset counter 41. When reading data, gate 68 is open from the sensing of the third short gap.

Title: Tension control
Inventor: WAITE ROLAND
IPC: B65H59/38
Filed: 1965-10-22
Abstract: 1,110.718. Automatic tension control. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 July, 1966 [22 Oct., 1965], No. 44830/65. Headings DID and D1J. [Also in Division G3] Yarn tension is controlled by (a) a yarn guide positioned between a supply or collecting passage and a yarn handling machine, the guide being movable about a mean position in response to tension variations, (b) an electro-magnetic clutch-brake system to drive the package, and (c) a means, e.g. a potentiometer, which is operatively connected to the yarn guide, responsive therewith to tension variations, for controlling excitation of the electro-magnetic clutch-brake. The electrical signal from the potentiometer can control the excitation of the clutch-brake system via a circuit, see Fig. 4 (not shown), so that in the mean position of the guide there is no excitation of the electro-magnetic clutch or brake. Preferably the package is driven by a d.c. electric motor. As shown in Fig. 3 the clutch 18 and disc brake 21 are mounted on a common shaft 23, which also carries the package carrier 24, running in bearings 22, 27. The clutch and brake actuating coils, 17, 20 respectively, are mounted on base support 16. The drive pulley 28 is connected to the clutch plate 19 and runs about bearings 27. An increase in yarn tension causes greater excitation of clutch coils 17 and less of brake coils 20 and vice versa. The electric motor may be connected directly to shaft 23. The yarn may optionally pass through fixed guides in addition to the moving guide, see Figs. 1 and 2 (not shown). The yarn may be of a synthetic thermoplastic resin and may be fed to or from a multiposition drawing machine. A traverse means can be used to lay the yarn if it is being wound onto the package.

Abstract: 1488365 Ignition systems; timing ignition ROBERT BOSCH GmbH 18 Oct 1974 [20 Oct 1973] 45159/74 Heading F1 In an I.C. engine ignition system, the timing is effected at a crank-shaft angle dependent on engine operating conditions by a binary number comparator 38 producing an output ignition triggering signal when the reading of an angle counter 37 exceeds that of an interpolating counter 36. The interpolating counter 36 counts pulses, dependent on engine speed and in accordance with a timing curve, from a digital interpolator 34, receiving input signals from a signal generator 20 providing data on the angular position and speed of rotation of the crank-shaft, from an oscillator 28 providing data on inlet manifold depression, and additionally from an input 35 providing data on a further operating condition such as engine cooling water temperature. As shown, the angle counter 37 receives a reset signal from a switch 21 actuated by a cam 22 on the crank-shaft, and counts the pulses from a toothed wheel 24 and pick-up 25, 26. Again, the toothed wheel arrangement can be replaced by a photo-cell arrangement. More than one switch 21 may be provided for multi-cylinder engines. To allow further processing of output fn from the signal generator 20 in digital computing circuits, the frequency of its signal is multiplied in a multiplier circuit, Fig. 2, (not shown), including a strobing stage (43) and a frequency divider (47), and producing an output signal (fnv). Further detailed circuits of the various components and stages are given. Again, Fig. 10, (not shown), a trigger circuit for a multi-cylinder circuit is provided, and includes a cylinder marking generator (81) supplying a reference pulse to counter 37 for each individual cylinder. Alternatively, the cylinder marking generator (81) is omitted, and switch 21 is closed several times in each crankshaft revolution to provide a pulse for each cylinder. Various cylinders may have differing firing angles, either by adjusting various cams 22 on the crankshaft with a number of switches 21, or by means of the cylinder marking generator (81).
