Abstract: 1290951 Photogrammetry HOBROUGH Ltd 9 March 1970 [23 May 1969] 11201/70 Heading H4D Inphotogrammetric apparatus of the type described in Specification 1,231,998, a parallex discriminator system for determining parallex differences in the video signals 16, 17, Fig. 1, resulting from the pair of scanned stereo-photos, and producing signals for distorting the raster scan of the photos to remove said parallex differences comprises: a frequency band selection and video/digital converter 18 in which the video signals 16, 17 are divided in channels E, D, C, B, A into frequency bands having centre frequencies f 1 ,f 2 ,f 3 ,'f 4 ,f 5 , in the ratios 1:2:4: 8 : 16 and the pair of frequency component signals in a channel, e.g. A, B<SP>1</SP>, Fig. 5, are converted in sample and clamp means 54 &c. into digital waveforms C, D<SP>1</SP> in accordance with their slope during -cycle sampling intervals; a paralleled array of X-parallex discriminators 20, Fig. 1, 58 &c., Fig. 2, receiving the digital waveforms from the respective sample and clamp means and producing signals on "up" or "down" outputs depending on whether the component in the left video signal 16 is leading or lagging the component in the right video signal 17. The "up" and "down" signals respectively set and reset the respective bi-stable of time delay equalizer 140 (21). The digital outputs of the bi-stables are simultaneously available in parallel form. Due to the frequencies f 1 , f 2  &c. increasing in powers of two the output of the time delay equalizer is in binary code form, with the "1" output from the bi-stable 141, in the lowest frequency channel giving the most significant (2<SP>4</SP>) digit. The thus-produced parallel binary coded representation of the phase difference or parallex between the left and right video signals is converted into serial format at 22 and averaged from one scan line to the next in lateral integrator 23. The line average signal is next averaged over sections of the field by accumulator 24 and the resultant signal is converted back to analog form at 26 for use as the raster distorting signal.

Abstract: 1295980 Measuring liquid level and density: measuring force HYDRO APPARATE - BAUANSTALT ZUCKER & CONTZEN 31 Dec 1970 [19 Jan 1970] 61988/70 Headings G1H, G1S G1W A device for measuring the level and the density of a liquid 1 comprises a balance arm 7, a cable 3 carrying a liquid displacing element 2 at one end and being wrapped around drum 13 at the other, a wheel 8 mounted on arm 7 over which the cable passes, a first motor 17 for winding and unwinding the cable from the drum and a second motor 18 for varying a restoring force applied to the beam 7 through a spring 9. Any movement of the balance arm 7 from its horizontal datum position causes counterweight 27 to operate one of two switching elements for controlling motor 17 or 18 according to the setting of switch 15. When measuring liquid level switch 15 is set to control motor 17 and arm 7 is in its datum position when element 2 is immersed to a depth h. When the liquid level rises or falls, the balance of arm 7 is upset causing it to tilt and actuate one of the switching elements to switch on motor 17. Motor 17 rotates the drum 13 to unwind or wind the cable on the drum, depending on which of the two switching elements is actuated, to lower or raise the element 2 until it is again immersed to the depth h when arm 7 again occupies its datum position and motor 17 is switched off. Thus the liquid level is given by the angular movement of motor 17. Drum 13 is arranged so that as it rotates it moves axially cf Fig. 2 (not shown) so that the cable is wound neatly on the drum and to effect compensation for the varying weight of cable acting on the arm. This latter compensation is effected by a cam follower 12 mounted on one end of a lever 11 and engaging cone 14 on drum 13. As the drum moves axially lever 11 is caused to tilt and vary the the force applied by a spring 10 to arm 7. To measure the density of the liquid, motor 17 is actuated by switch 16 to lower element 2 to the depth at which the density is measured. Switch 15 is set so that motor 18 is actuated by counterweight 27 and the switching elements. Motor 18 drives a rack connected to spring 9 and thus varies the tension in spring 9 until the arm becomes balanced again, when motor 18 is switched off. The density is then related to the angular position of motor 18. The density may be measured at several depths.

Abstract: 1310359 Car head-lamp systems JOSEPH LUCAS (INDUSTRIES) Ltd 10 July 1970 [23 July 1969 14 Oct 1969] 36946/69 and 50312/69 Heading G1A A lighting system for road vehicles comprising a light source, a photo-cell and a pair of shutters which obscure the light source and the photo-cell in a rest position when the light source is not energized; however whenthe light source is energized the shutters are moved to an inoperative position uncovering the light source and wherein light can fall on the photo-cell so that whenever the light from an oncoming vehicle is incident upon the photo-cell, means operable in response to stimulation of the photo-cell are activated to move the shutters so as to cut off sufficient of the projected light beam to avoid dazzling the driver of the oncoming vehicle. In one embodiment, Figs. 1 and 2 a lens 14 and an aperture 12 in a bulkhead 11 define part of a projector including a high intensity bulb having its filament 16 at one focus of a part ellipsoidal mirror 17. Any light from an oncoming vehicle is directed by a lens 15 through an aperture 13 on to a photocell 19. A pair of shutters 21, 22 are carried by a spool 23 which is slidably mounted on one limb 24 of a magnetic frame 25 with a permanent magnet 27, and on the spool 23 is a winding 28 energization of which causes movement of the spool 23 along the bar 24. The frame 25 is inclined to the horizontal so that gravity urges the spool and the shutters to the aforementioned rest position. The light source 16 is connected in parallel to a resistance bridge and a battery via a switch, Fig.3, (not shown). The winding 28 is connected to the bridge network which comprises three resistors (41), (42) and (39) and a transistor pair (37), (38) controlled by the photo-cell. When the switch is activated current will flow through the light source, the resistance bridge and the winding 28 thereby causing the source and photo-cell to be unmasked. The associated transistor circuit is designed so that when the photo-cell is activated the resistance of the transistor pair is decreased causing the current to flow along a different path in the bridge and in a different direction in the winding 28 thus effecting positive movement down the bar 24 of the spool 23 and shutters 21 and 22. This movement continues until the shutter 22 prevents the oncoming light from reaching the photo-cell. Alternative embodiments are dislosed in which the spool is returned to its rest position with the aid of a spring or in which the winding is centre tapped to form two windings.

Filed: 1970-12-04
Abstract: 1337745 Fluid regulation J C ECKARDT AG 4 Dec 1970 57770/70 Heading G3H In a fluid amplifier 1, a power nozzle 2 emits a jet into a mixing duct 3 and so entrains fluid within a suction duct 5, the degree of entrainment being dependant upon the strength of a signal applied to a control nozzle 6. The signal at 6 acts to alter the resistance to flow of fluid moving within this duct 3 and towards a diffuser 4. Thus, an increase of pressure within control nozzle 6 results in an increase in pressure within suction duct 5. In modifications Figs. 2b, 3, 4, and 5, (not shown), the suction duct may open into the narrow part of duct 3 but upstream of control nozzle 6; the supply to the suction duct may be throttled by one or more of fixed and variable throttles; and the control nozzle 6 may be arranged to direct flow either at an angle to the flow from nozzle 2 or counter-current thereto. In the embodiment shown, the amplifier input is constituted by the control signal at 6, whilst the output is derived from the suction duct 5.
