Counter 3a counts pulses corresponding to a time interval of one second, counter 3b to a time interval of ten seconds and so on. Binary code signals are sent from the counters to respective matrix circuits 4a to 4f which convert the signals to further binary signals corresponding to the number of segments (seven) in each time display unit 6 1 to 6 6 . The further binary signals are applied to the bases of respective transistors e.g. T 1  to T 6 , Fig.5, of selector circuit 5a, Fig.2, whereby to activate selected ones of the segments L 11  to L 17  of the respective display unit 6 1 . To correct the time setting, e.g. in accordance with a radio time signal, a switch S o  is closed causing the resetting to zero of all the counters. Switches S 1  to S 6  are then closed to digitally advance the respective counters. Each display unit comprises a glass panel 17 Fig. 6, and back glass 19 with nematic liquid crystal in the space between. A transparent electrode 18 is deposited on the inner surface of 17 and a nickel layer 20 which forms the seven segments is deposited on the inner surface of 19. Spacers 21 are of plastics and the unit is sealed air-tight. Lighting electrodes 13, 14 are connected to the timepiece power source e.g. a battery and serve to distinguish the hour display from the minutes display and the minutes from the seconds display.

Title: Ultrasonic flowmeters
IPC: G01F1/66
Filed: 1971-04-19
Abstract: 1338436 Acoustic flow-meter THOMSON CSF 19 April 1971 [17 Feb 1970] 21246/71 Heading H4D A fluid flow meter includes a pair of transducers for simultaneously transmitting ultrasonic pulses towards each other obliquely across a pipe, means for producing a rectangular pulse of a length equal to the difference in the up- and down-stream propagation times, a third transducer transmitting perpendicularly to the fluid flow, a fourth transducer receiving said pulses and connected to the first input of an amplifier whose output is connected to the third transducer for producing a signal whose frequency is related to the velocity of sound in the fluid, means for deriving therefrom pulses having a P.R.F. proportional to the square of the said frequency and means for counting said pulses during said rectangular pulse. Master oscillator P causes time base BT to trigger generator G to produce simultaneous transmissions from transducers A, B. Received signals are mixed with a signal from oscillator P and after passing through zero crossing detectors Ph1, Ph2 trigger and reset bi-stable ST whose output enables gate ET allowing pulses from clock H to pass to counter CT. The clock H frequency is made inversely proportional to the velocity of sound in the fluid and the counter output is thus proportional to the fluid velocity. Transducers X, Y are connected via an amplifier in a sing-around loop whose frequency is detected by a discriminator which produces a voltage proportional to the deviation from a known frequency, this voltage is squared and used to control the frequency of an oscillator whose output is connected to the gate ET. Several pairs of transducers may be used to measure the fluid velocity at several points along a pipe and also to study the velocity profile. The transducers may be mounted on elongate "necks" (Fig. 6, not shown) if the fluid is hot, and may also be provided with a quarter-wave plate arrangement for reducing reflections. (Figs 7-8, not shown).

Title: Improvements relating to reflection reducing surfaces on glass
IPC: C03C15/00
Filed: 1943-12-20
Abstract: 570,717. Low-reflection glass surfaces. RADIO CORPORATION OF AMERICA. Dec. 20, 1943, No. 21333. Convention date, May 28. Drawings to Specification. [Class 97 (i)] A method of producing a low-reflection surface or layer on glass comprises subjecting the surface layer to gas or vapour from an acid solution until its density is so reduced that its index of refraction is appreciably lower than that of glass, the solution and the glass surface being maintained at substantially the same temperature during the process, for which purpose the hydrofluoric acid solution employed in the similar process described in Specification 558,098 has an organic substance, such as ethylene glycol, dissolved in it to lower the vapour pressure, or alternatively is replaced by a fluosilicic acid solution. In either case the necessity for maintaining the glass at a higher temperature than the solution is avoided. In an example, the solution consists of 45 per cent by volume of ethylene glycol and 55 per cent of 1 per cent hydrofluoric acid. This is contained in a wax-lined copper tray which is covered by the sheet of glass under treatment, on top of which is placed a copper plate. In another example, a 16 per cent solution of fluosilicic acid, without any addition, is used in a similar tray, the glass being covered by a lid in the form of an inverted metal tray. Smaller pieces of glass are treated by supporting them in openings in a metal plate covering the tray:

Abstract: 1347602 Photo-electric measurement of colour temperature COMMISSARIAT A L'ENERGIE ATOMIQUE and INSTYTUT BADAN JADROWYCH 8 May 1972 [7 May 1971] 21369/72 Heading G1A The colour temperature of a source 1 is measured by modulating its output by means of a filter wheel 2 carrying two differently coloured e.g. interference filters, and passing the modulated beam via an angularly adjustable inter-  ference filter 3 to a photo-detector. Adjustment of the filter 3 changes the ratio of its transmission for the two wavelengths of the filters of wheel 2. Thus the photo-detector output can be used through servo mechanism 6 to adjust the angle 5 (and thus the ratio) until the components. of the detector output corresponding to the two filter colours are of equal magnitude e.g. using a null method. The final position of the filter 3 is indicative of the temperature.

Filed: 1976-05-24
Abstract: 1516577 Baling presses PERSONER VERKSTAD AB 24 May 1976 [28 May 1975] 21404/76 Heading B5F A method of baling material, e.g. paper, which tends to expand when relieved of pressure comprises compressing the material in a channel 11 against a formed bale held by clamps 16, releasing the clamps 16 and displacing the compressed material and bale towards the discharge end of the channel when a pre-determined compressing force has been applied to the compressing plunger 14, and re-applying the clamps for the end part of the plungerstroke to compensate for any expansion of the the material during the displacement. Apparatus for performing the method includes pivoted flaps 16 in the side walls and top of the channel 11 which are operated by hydraulic cylinders 22 for clamping the bale. A mechanism 17 for tying wires or bands about a bale when the plunger is fully advanced is connected to a measuring wheel 19 and a counter. A wall 18 is pivoted downwards to pre-compress material supplied through an opening 10 and close the channel 11. Sensors 2, 3 respectively detect when the plunger is in forward and rearward positions, and an adjustable sensor 1 re-applies the clamps. At the start of a compression stroke the hydraulic circuit is set, Fig. 2, to supply the plunger-cylinder 20 and, through valves 23, 24, cylinders 22 from a line 21. When the pressure of fluid in line 21 reaches a pre-determined value valve 23 is actuated to maintain this pressure to the cylinders while that to the plungercylinder 20 increases until a relief valve 26 is actuated for releasing the pressure in cylinders 22 and thus unclamping the abutment bale. Continued movement of the plunger now displaces the forming and formed bales until the clamps 16 are re-applied when sensor 1 is triggered for resetting a valve 25 by-passing valves 23, 24. At the end of the stroke sensor 2 is actuated. If the bale is of desired length, as determined by the counter, a tying operation is performed before the plunger is returned.

A super - heterodyne radio receiver having two R.F. tunable circuits, comprises means for tuning those circuits to frequencies which differ from one another by twice the receiver I.F., means to render one of the circuits inoperative when tuned over a first frequency range, and means to render the other of the circuits inoperative when tuned over a second frequency range. The invention is described as applied to a known " TACAN " airborne apparatus so as to permit air-to-air ranging for collision warning or so as to determine the range between a tanker aircraft and an aircraft to be refuelled therefrom. It is stated that the normal frequency channelling arrangement between aircraft and ground beacons is as summarized in Fig. 1, and in Fig. 2 the aircraft apparatus includes in the receiver a channel selection switch 11 which energizes a tuning motor 14. In the usual operation of the apparatus, relay contacts are as depicted by broken lines but when switch 38 is set for air-to-air (A/A) ranging, earth is put on to the operating windings of relays 23, 32, 37 and 39 thereby causing the respective contacts to take up the solid line positions shown. Relay 23 transfers earthing from input circuit 18 to input circuit 19; relay 32 causes by-passing of delay line 31 and circuit 33 functions as an amplifier. Generator 24 functions normally to produce a double pulse interrogating signal, Fig. 3A (not shown); any ground beacon reply is rejected since circuit 19, tuned thereto, is earthed and a transponding aircraft is arranged to reply on circuit 18 frequency (the image of circuit 19 frequency) with a single pulse, Fig. 3C<SP>1</SP> (not shown). Range circuits 34, in the known manner, cause the range to the transponding aircraft to be displayed on indicator 36. The transponding mode of the apparatus of Fig. 2 is described with reference to waveforms illustrated in Fig. 4 (not shown). To permit correct A.G.C. operation with the lower pulse repetition rate in A/A ranging, a long time-constant integrating network 38b is provided; or, to permit long distance ranging, the receiver may be operated at maximum gain. " OR " circuit 46 prevents damage to the receiver during frequency channel selection in the A/A mode and receiver muting during mode selection is afforded by a circuit 43. Operation without modification of the normal decoder circuits may be accomplished by using a modified arrangement, Figs. 5, 6 (neither shown).
