Abstract: 1,239,244. Controlling shearing machines. HAMMERLE A.G. 20 Sept., 1968 [22 Sept., 1967], No. 44870/68. Heading B3W. A switch arrangement on plate shears only actuates the shear when a workpiece engages a gauging strip firmly and " permanently ", i.e. it does not actuate the shear if the workpiece only briefly engages the stop. The switch arrangement comprises a first group of switches 1, a delay relay 12 for a second switch 2, a switch member in the form of a relay 3 with two make contacts 4, 5 and a control member 6. The time relay is preferably adjustable. In correct operation, a workpiece 10 is pushed against a gauging stop 9 incorporating switches 1 which are thereby closed, the relay 3 receives current from terminals Ph and O and contacts 4 and 5 are closed. The control member 6 receives current through contact 4 and causes a hold down 8 to be actuated. The time relay is set so that it closes the switch 2 when the hold down has reached clamping position causing the relay 3 to receive current through the switch 2 and contact 5. The control member remains energized and causes the shear 7 to operate. Meanwhile the stop is swung away and the switches 1 are opened. If the workpiece is pushed carelessly against the stop so that the switches 1 are closed only momentarily the control member receives current only momentarily and the operation stops. Similarly if the workpiece is correctly positioned but is removed from the stop before the hold down has clamped it, i.e. before the switch 2 is actuated the operation stops.

Abstract: 1311137 Magneto-optical read-out arrangemerits; modulating light KOMBINAT ROBOTRON VEB 27 Oct 1970 50999/70 Heading H3B and H4F A sheet of magnetic material 2 having areas 3 magnetized to represent data bits "0" or "1" has a sheet of a material 1 having a higher refractive index thereon; when a beam of polarized laser light is incident on the boundary between the sheets at the critical angle α g , the reflected beam is γ rn  for a "1" but is offset to γ rv  for a "0". Thus, by using a mask 5 and detectors 4<SP>1</SP>, 4<SP>11</SP> to determine the position of the reflected beam the data may be read out. The offset appears to occur because at the critical angle the beam penetrates a significant distance into the sheet 2, and is effectively reflected from within that sheet. The critical angle is a function of magnetization, so that while a beam incident at α g  is offset by a "0", it is not offset by a "1". The offset may be of the order of 0À1 mm. for infra red light, which gives an improvement in the signal/noise ratio relative to the Kerr effect of 2-4 orders of magnitude. The offset beam is slightly broadened, so that its energy/unit area is reduced, and this may also be used to read out the stored data.

Abstract: 1312797 Photo-electric control of braking system, liquid level indication GIRLING Ltd 22 July 1971 [11 Aug 19701 38544/70 Headings G1A G1H [Also in Division F2] In an anti-skid braking system in which the braking pressure is relieved when the deceleration of the braked wheel exceeds a predetermined value an optical signal generating means transmits light pulses from a source to a photo-electric cell at a frequency dependent on the speed of rotation of the braked wheel and an electric current generated by the cell energizes the means controlling the braking pressure. Each wheel has an apertured or transparent modulator 1 which interrupts the light falling on the cell, the light singals being transmitted for example via light transmitting cables 5, 7, Fig.3. Instead of separate light sources at each wheel a common light source 6 comprising a lamp 8 energized by a battery 3 may be used, the light being transmitted to the wheels by cables 7 and returned to the control module 4 by cables 5 and warning lamps 10, 11, 12 indicating failure of the module 4 and indicating fluid level in reservoirs for the braking system are included. The cables 5, may be D-section units assembled in a single cable so that light passes down one half of a cable and is reflected back in the other half. In another embodiment Fig. 4 light from a source 16 is transmitted to each wheel by cables 17 and a photo-electric cell on each wheel feeds a current via electrical cables 18 to the module 4. A further light-transmitting cable 21 is formed at its free end with a reflective or refractive surface formed by a mirror or prism 22 and a similar cable 23 connected to a warning device 24 for indicating fluid level in a reservoir 25 has a mirror or prism 26, a float 27 normally preventing light from being transmitted from one to the other until fluid level falls below a predetermined value. The modulator 1 may, as in Fig. 5 for example, comprise a rotatable cup-shaped member having a peripheral skirt 28 with identical notches 29 and teeth 30 between them straddled by a U-shaped fitting 31 carrying light-transmitting cables 34, 35, or maybe a flat disc 44, Fig.12 having reflecting and non-reflecting surfaces 45, 46. Alternatively, the disc may be transparent or translucent and with teeth 50 having reflective surfaces 51, 52 Fig.15 or opaque with similar teeth. The light source, which may be a lamp or a solid state device, and detector may be positioned adjacent the modulator skirt, light guides being absent, Fig. 10, and Fig. 11 (not shown). Optical fibre bundles may be used some of which send light to and some from the area of the modulator. Two light cables may monitor the same modulator.
