Abstract: 1335540 Recording and playback CANON KK 15 Dec 1970 [15 Dec 1969 19 Dec 1969 2 March 1970] 59447/70 Heading G5R Modulated carrier signals (Fig. 1b) recorded optically as a diffraction grating pattern on a film are demodulated by running the film at a constant speed, illuminating it with coherent light and combining together different order diffracted waves. In a first embodiment (Fig. 2), a beam from a laser 2 is split at 3 and the parts used to illuminate the moving film 1 from different directions; the zero and first order diffracted waves travelling in the same direction then combine at a pinhole 8 and photo-cell 9 to give only the modulation signal. In a second embodiment (Fig. 3, not shown) the film is illuminated by a single beam and mirorrs (11, 12) and a beam-splitter (13) are positioned to realign the zero and first orders diffracted in different directions at the film. In third and fourth embodiments (Figs. 4, 5, not shown) a diffraction grating is placed either in front of or behind the film to either illuminate the film at two angles or to combine waves proceeding in different directions, as in the first and second embodiments. In a fifth embodiment (Fig. 6, not shown) a two beam system is used which counteracts lateral movement of the film. A recording system incorporates a mechanical or Faraday or Kerr shutter (19, Fig. 7, not shown), and an ultrasonic or moving mirror element (20).

Title: Precision Pneumatic Seed Drill
IPC: A01C7/04
Filed: 1979-02-21
Abstract: A piston 5 reciprocating in a cylinder 4 is provided with a seed receiving pocket 8 in fluid communication via a port 9 with the lower end of the piston. At the upper end of the stroke of the piston the pocket 8 is aligned with a seed inlet aperture 7 in the cylinder wale and due to suction created in the space below the piston a seed is drawn into the pocket. At the lower end of the stroke of the piston the pocket is aligned with a seed outlet aperture 10 in the cylinder wale are due to pressure created in the space below the piston the seed is ejected. Pressure created in the space above the piston as the piston rises causes a jet of air to be directed, via a port 6, at the inlet aperture 7 to blow excess seeds away. <IMAGE>

Title: Switching illuminated displays
IPC: H05B37/02
Filed: 1979-07-10
Abstract: An arrangement for controlling the switching of an array of lamps connected to a multiple-way output socket (12) includes direct earth and neutral connections and live connections to the lamps through Triacs (14) controlled by drive circuits (18). The triacs are either switched in strict sequence according to some pattern and speed selected by switches (32, 40, 48) or in response to a control signal derived from an audio signal which is amplified and distorted according to a logarithmic scale by an audio amplifier (22) which receives the audio signal as an input. An automatic changeover circuit, after an absence of any control signal from the amplifier (22), automatically causes the circuit to revert to a strict sequence for operating the Triac drive circuits (18) until a control signal once again appears at the output of the amplifier (22). <IMAGE>

Title: Improvements relating to the detection of turbulence and/or shock waves
Inventor: CLARK DR JAMES
IPC: G01R33/028
Filed: 1979-12-06
Abstract: An electromagnetic field detector is used to detect either the magnetic or electric field component of an electromagnetic field generated by turbulence and/or shock waves. The detector preferably takes the form of a magnetic field detector 4 comprising a pole piece 6 and a pick up coil 8. The detector can be used for detecting stall conditions over an aircraft wing section and can also be incorporated into an electromagnetic surveillance system which operates predominantly in the frequency range 10 Hz to 100 KHz. In this frequency range most of the energy is in the form of 'surface waves'. By analysing the electromagnetic field object signatures can be developed which can later be used to identify unknown objects. By triangulation techniques utilising two spaced detectors (Fig. 4) the positions of detected objects may be determined. Detection of over the horizon and low flying aircraft and of submerged submarines is possible. <IMAGE>

Patent GB-2040485-A (GB)
Title: Electronic Flash Unit
IPC: G03B15/05
Filed: 1980-01-15
Abstract: A flash tube 10 has a photoelectric time control 17, 18 and a supplementary time control 35 for switching off the tube after a predetermined time if the photoelectric control has not already done so. This is to ensure that the supply capacitor 13 does not become completely discharged. The recharging of the capacitor 13 which is only partially discharged, makes more efficient use of the current storage supply 11, reducing the need for frequent recharging of the current storage supply. Fig. 2 (not shown) shows an alternative form of supplementary control 35. <IMAGE>
Patent GB-2047839-A (GB)
Title: Geneva mechanism
IPC: F16H27/06
Filed: 1980-03-10
Abstract: A geneva mechanism has a base (10) on which a geneva wheel (11) and a cam wheel (14) are mounted for rotation about respective axes (12, 15) the cam wheel having a roller (16) engageable with slots (13), in the geneva wheel (11), to impart stepwise rotation thereto. The geneva wheel has rollers (17), two of which are simultaneously engageable by a part-cylindrical surface (18) on the cam wheel (14), to lock the wheel (11) against rotation. This simultaneous engagement is such as to impart a slight stress between the parts and thereby to eliminate backlash. Additionally the geneva wheel (11) is maintained under control of the cam wheel (14) during entry and exit of the roller (16) into and form the slots (13), by location of the surface (18) and a further, parallel surface (19) between one or other pair of the rollers (17). Further rollers (22) on the wheel (11) are engageable with a spring-biased bolt (25) to decelerate the wheel. <IMAGE>

Title: Token-operated mechanisms
IPC: G07F15/12
Filed: 1980-04-09
Abstract: A token-operated mechanism is provided, for instance for controlling and timing the operation of a coin- operated tumble drier. The mechanism comprises a cover 1 with apertures 2, 3 for receiving coins or the like of two different denominations. Two chutes 23, 24 receive accepted tokens from the respective apertures. A plate 5 is pivotally mounted to the cover 1 for movement in either direction according which value of coin has been inserted. Thus a coin inserted through the aperture 2 or 3 is directed by movement of the plate into a corresponding chute 24 or 23. A microswitch 27, 28 for each chute has a trigger wire 25, 26 extending into the chute to detect the passage of a coin and signals a timer to provide a timed period corresponding to the value of the coin. The mechanism thus allows coins of more than one value to be used. <IMAGE>

Title: Rotary drive for a hammer drill
IPC: E21B3/035
Filed: 1980-05-29
Abstract: The drive has a sleeve 4 to which the drill bit is coupled. The rotary drive of the sleeve includes a drive gear 3 and a friction clutch formed by a set of gears 5 which mesh with the drive gear and are axially movable and rotatable relative to the sleeve 4. The clutch also has friction plates 6 and 11 which are axially movable along and rotationally fixed relative to the sleeve. The opposite outer plates 6 and 11 are biased by means of a nut 7 and a spring 8. The nut 7 has on the side directly engaging the outer friction plate 11 holes 9 for accommodation of balls 10 and the friction plate 11 engaging the nut 7 has corresponding recesses. The balls are received in the nut holes 9 and plate recesses 12 with axial play. This is less than the depth at which the balls 10 enter the recesses 12 or the holes 9. For adjustment the nut is rotated relative to the sleeve. This initially increases the spring loading. The loading decreases to the new value when the balls 10 drop into the successive plate recesses 12. The biassing is on the unloading curve of the hysteresis curve of the clutch. <IMAGE>

Title: Ejector Assembly
IPC: F04F5/48
Filed: 1979-05-08
Abstract: In a gas turbine engine an auxiliary airflow is provided to power accessories. This auxiliary airflow is obtained from a bleed aperture 7 which is constructed immediately downstream of a diffuser vane 3. This high energy air from the diffuser 1 is used as the primary airflow in an ejector 10 to draw ambient air into the auxiliary airflow to lower the temperature of the bleed air. The ejector is constructed to adjust the amount of ambient air automatically according to the energy of the bleed airflow by means of a piston actuated spike 13 mounted for sliding movement in the primary nozzle 11. The spike 13 varies the volume of flow through the primary nozzle 11 according to the pressure exerted by the airflow on the piston. <IMAGE>
