Title: Device for determining the location of orientation of an object in a designated environment
IPC: G06F3/033
Filed: 1973-11-28
Abstract: 1449050 Optical position finding AUSTRALIAN NATIONAL UNIVERSITY 28 Nov 1973 [30 Nov 1972 4 July 1973] 55185/73 Heading H4D To determine the position of an object 21, Fig. 2 carrying photo-electric detecting means and movable on a plane 12, one or more light beams 13 are swept over and parallel to the plane surface 12 and a co-ordinate of the object is formed by measuring the time interval between a pulse produced by the photoelectric means as it is swept by the light beam and a reference pulse produced by the light beam passing through a reference direction. In Fig. 1, the light beam 13 is produced by a laser 11 and caused to scan by a rotating mirror 16. In Fig. 2, the anticlockwise scanning beam, by falling on two mirrors 18, 19, scans object 21 from three different directions, i.e. a clockwise X sweep by reflection from mirror 18, an anticlockwise Z sweep between the mirrors, and a clockwise Y sweep by reflection from mirror 19. The reference pulses are produced by fixed photo detectors 31, 32. A clock-pulse generator feeds pulses into a first register counter which is started and stopped by consecutive reference pulses and this gives a count proportional to the duration of the sweep, and also into a second register counter which is started by a reference pulse but stopped by the beam sweeping the object 21. The ratio of the resulting two counts indicates a digital co-ordinate. In the 3- dimensional embodiment of Fig. 5 the object 40 is swept by three fan beams 43, 51, 61 scanning in respective directions perpendicular to their planes and produced from respective pencil beams 41, &c. by part cylindrical reflections 42, &c. The reference pulses are produced by pairs of "start of scan" and "end of scan" photodetectors 48/49, 58/59, 68/69.

Title: Method and Apparatus for Measuring and Recording the Absorption of Electromagnetic Radiation
IPC: G01N21/31
Filed: 1966-12-16
Abstract: 1,172,390. Photo-electric absorption analysis. INCENTIVE RESEARCH & DEVELOPMENT A.B. Dec.16, 1966 [Dec. 22, 1965], No. 56408/66. Heading G1A. In absorption analysis of a sample, a movable filter is used to provide pulses of radiation alternating in frequency between one which is partially or entirley absorbed by the sample and another unaffected by the sample. The pulses are separated into groups corresponding to the different frequencies and the ratio of the amplitudes of the two groups is recorded. Ultraviolet light from a hydrogen lamp 1 is focused by lenses 2, passed through filters 3 and reflected by mirror 4 before passing through the rotating filter arrangement 6, 7 driven by a motor 8. A rectangular crosssection beam is provided by diaphragm 9 and the beam is passed through the sample. This is contained in an electro-phoresis tube 10 which is rotated about its axis by belt 21 and reciprocated across the beam. Current is supplied to the tube via supports 19, 20. The beam then passes through a filter 12 removing visible light, before reaching the photo-multiplier 11. Signals from the photomultiplier are fed to a recorder 13 via alternate channels of a two-channel recorder system including amplifiers. A switch synchronized with motor 8 arranges that the signals due to radiation which is absorbed by the sample pass through the sample channel and signals due to radiation unaffected by the sample pass through the reference channel. The recorder records the ratio of these signals as a value proportional to the absorption of the sample. A feedback loop from the reference channel to detector is provided to maintain the reference signal amplitude constant. Instead of using a movable sample tube, 10, a stationary through flow cuvette and a scanning light beam may be used.

Abstract: 1410868 Wired television system INTERNATIONAL STANDARD ELECTRIC CORP 14 Dec 1973 [14 Dec 1972] 58012/73 Heading H4R In a cable television system having more than one transmitting stations 3 and 12 feeding respective distribution networks 1 and 2 some signals which are not normally receivable at one transmitting station 12, but are receivable at another station 3 are digitally encoded and transmitted to the one station from the other over the respective distribution networks and a bridging cable 30. As described N analogue tv signals are received at each station and distributed over the distribution network in analogue form in the frequency band 100 to 270 MHz. Four channels of tv receivable only at station 3 are sampled and converted to binary digital form with a bit rate of 29À6 M bits and then time multiplexed to provide a 120 M bit/sec. signal. The binary signal is converted to ternary code to give a 90 M bit/sec. signal which after shaping is transmitted in base band with the 100 to 270 MHz analogue tv signals. The resulting signals are fed over the distribution networks which are provided with repeaters, Figs. 4 to 7 (not shown), in which the bands 0 to 90 and 100 to 270 MHz are separated out and the 100 to 270 MHz signals fed through a linear amplifier while the 0 to 90 MHz band is either directly connected or, every fourth repeater, fed through a digital regenerator. After passing over the bridging cable and back to station 12 through network 2 the digital signals are recovered from the line via a 0 to 90 kHz filter, the digital signal regenerated, converted back to binary form, demultiplexed, decoded and applied to the transmission circuits for distribution over the network 2 in analogue form in a manner similar to that of the N signals originating at that station.

Title: Oscillatory output devices
IPC: B60S1/18
Filed: 1971-12-15
Abstract: 1410016 Windscreen wiper drive device DUNLOP Ltd 4 Dec 1972 [15 Dec 1971]  58711/71 Heading A4F [Also in Division F2 and H1] In a windscreen wiper drive device, continuous rotary motion is converted to oscillatory motion by a system of rotary cranks. An annular member 2 is continuously rotated about a fixed axis W within bearing 3 by an electric motor (not shown) via a flexible drive and worm gear 6. An eccentric member 8 is mounted within member 2 and rotates about a movable axis X which is parallel to axis W and displaced therefrom by a fixed distance. A spigot 10 on the member 8 engages in a socket 11 in output shaft 12 which is rotatable about a fixed axis Y, the shaft 12 projecting from housing 1, being coupled to associated windscreen wiper arm or arms. The spigot 10 and socket 11 are arranged for relative rotation about a movable axis Z. Thus the continuous rotation of axis X about axis W causes oscillatory angular displacement of axis Z about axis Y through an angle (32 degrees) Fig.2 (not shown), which is dependent on the inter-relationship between axes W, X, Y and Z. A parking mechanism for the wiper comprises a reed 21 and a permanent magnet 17 mounted on the housing 1. A ferrous shield 22 on the non- ferrous member 2 shields, once each revolution, the reed 21 from the magnet 17. When a control switch (not shown) is in its "off" position power is supplied to the motor via the reed, the device coming to rest on the next occasion that the shield 22 comes between the reed 21 and the magnet 17.

Abstract: 1356711 Data stores INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1971 [8 Jan 1971] 60296/71 Heading G4C Registers N, I (Fig. 4) between buffers A, B connected to the outputs 40 and inputs 84 of a shift register (not shown) are selectively included in or excluded from the data path between buffers A, B so that data may be inserted into or deleted from the shift register respectively. Initially a flag code is loaded at random into the shift register, the remaining data positions being loaded with dummy characters. During normal operation data from the register is fed back in via input buffer A, normal register N, gate 76 and output buffer B. To insert data into the register before a flag code, the path between the buffers A and B is extended by the additional register I. When the flag code is detected, it is transferred from register N into register I, new data from bus 49 being fed via gate 81 into the output buffer B. At the next memory cycle new data is read from the buffer B into the shift register and the flag code in register I is read via gate 85 into the buffer B for entry in the next cycle. To delete data following a flag code, the unrequired data is fed from buffer A into register N where its path is inhibited, subsequent data following a direct path from buffer A via gate 75 into buffer B. Delete codes are entered from data bus 36 into output-buffer B to replace the unrequired data, these codes being deleted in a subsequent cycle of the memory.

Title: Yarn stop motion means for a knitting machine
IPC: D04B35/14
Filed: 1978-09-15
Abstract: In the knitting of articles of clothing on multi head knitting machines the breakage of one yarn while a garment is being knitted results in a spoilt garment and if the machine continues to operate after it has finished that garment further spoilt garments will be produced until that machine has been stopped. The present stop motion is actuated if one of the yarns being fed to the knitting head breaks to prevent the machine from knitting another garment until the broken thread has been repaired but does not stop the machine until the spoilt garment is finished. A member rotated by the running yarn which holds a micro switch into one of two positions and if a yarn is running the micro switch which is held in the position permits the machine to be activated but in the event of the yarn not running, then the micro switch is operated into a position in which the machine is stopped at the end of a garment knitting cycle. <IMAGE>
