Title: Measurement, e.g. for use in analogue-digital conversion
IPC: H03M1/00
Filed: 1970-01-27
Abstract: 1299752 Analogue/digital converter SIEMENS AG 27 Jan 1970 [3 Feb 1969] 3998/70 Heading G4H In apparatus for converting a series of analogue inputs I (Fig. 1) to digital form including a capacitor store SP charged by the input signals and then discharged by a constant current source S 1  whilst clock pulses from a generator TG are accumulated in a counter Z until a threshold level is reached when the first source is disabled and a second source of lower current S 2  is enabled to charge the capacitor store back up to the threshold level, clock pulses of lower weight simultaneously being subtracted from the count, after the store has been charged by the jth input it is further charged by the source S 2  for j clock pulses these clock pulses also being subtracted in the counter Z. This is said to compensate for differential linearity errors. As described each measurement pulse increments a counter ZZ by 1 this count being compared with the count in counter Z reset to zero after each measurement. Whilst the source S2 is applied to the store the counter Z receives decremental pulses from the generator until the count in counter Z equals the count in counter ZZ when a gate G7 is closed to disable the source S2. The store is then discharged by source S1 to below zero and recharged by the source S2 back to zero.

Title: Improvements in or relating to the process of photographic reversal
IPC: G03C5/50
Filed: 1933-02-13
Abstract: 414,157. Photographic reversal processes. BAKER, T. T., The Hut, Hatch End, Middlesex, and DUFAYCOLOR, Ltd., 19, New Bridge Street, London. Feb. 13, 1933, No. 4416. [Class 98 (ii).] In a photographic reversal process, particularly for the production of multicolour screen pictures, the density of the image after the first development is measured, before or after reversal, and the reversed image is developed under conditions, e.g. time, temperature and strength of developer, determined from the density measurement. Thus, a negative image on a multicolour screen film as described in Specification 322,432, [Class 98 (ii)], is developed with a hydroquinone bath and then the image is dissolved in an acid bichromate or permanganate bath according as to whether the image is under- or over-exposed ; the average density of the image is then measured by a photoelectric cell and, after washing in a sulphite of soda bath, the film is re-exposed and developed for a length of time corresponding to the reading of the photo-electric cell. For the second development, a weak developer is used, e.g. one quarter strength, to permit accurate control. Preferably the film should have approximately double the normal weight of silver salts. The time of the second development may be obtained directly by calibration of the photo-electric cell galvanometer, or empirically from a curve showing the relationship between the galvanometer reading and time. According to the Provisional Specification, the film may be transferred from the second developing bath to a fixing bath automatically, at the expiry of the appropriate time, by means controlled by the photo-electric cell.

Abstract: 548,457. Controlling fuel-injection pumps. STANLEY, G. L. April 8, 1941, No. 4700. [Class 102 (i)] In a multi-plunger fuel-injection pump for internal combustion engines in which delivery is adjusted by simultaneously rotating the pump plungers relative to their barrels by means of a master-rod, and in which each plunger is rotatably adjusted independently of the others by means of separate sliding pieces which are individually adjustable along the master-rod, a sleeve 17 is disposed between each sliding piece 14 and the master-rod 19 and is in screw-threaded engagement with one of these parts and engages the other part for common translatory movement, so that each sleeve can be rotated individually to displace its co-acting sliding piece along the rod at will. Rotation of the sliding pieces is prevented by pairs of ears 15 engaging in grooves 16 in the pump casing 11. In the form shown, the sleeves 17 are screw-threaded on to the rod 19 and adjacent ends of each pair are slotted or castellated at 26 for separate rotation by a tool inserted through cover plates. Axial movement of the sleeves relative to the sliding pieces is prevented by circlips 18 sprung into grooves in the two parts, and accidental rotation of the sleeves within the sliding pieces is prevented by means of spring-pressed plungers 31 arranged longitudinally in the sliding pieces and having pointed ends to engage the chamfered ends of radial detents 30 which engage in V-shaped serrations 29 in the sleeves. The pump plungers may be connected to their operating cross-heads by means of breaking sleeves the webs of which break under excessive load.

Title: Direction finding equipment with at least two antennae systems
IPC: G01S3/14
Filed: 1974-02-01
Abstract: 1,446,815 Radio direction-finders; aerials LICENTIA PATENT-VERWALTUNGS-GmbH 1 Feb 1974 [6 Feb 1973] 04846/74 Headings H4D and H4A A direction-finding equipment comprises at least two directional aerial systems, and a further aerial system the signals from which are indicative of deviations in the received waves from a pre-determined direction of polarization and/or a pre-determined angle of elevation. Said signals may be used as criteria for the operation of the equipment for direction-finding when said deviations are within acceptable limits. As described, two loop aerials R1, R2, Fig. 1, are disposed in vertical planes which are at right angles to each other. The further aerial system consists of two semicircular loop aerials R3, R4 which are located in a horizontal plane, and which are so interconnected that the voltages induced in them are added. A vertical sense aerial H is also provided. Outputs from the aerials R1, R2 are processed in units V1, V2 and are applied to the orthogonal deflecting electrodes A1, A2 of a cathode-ray tube (CRT). The voltages from the units V1, V2 are also fed to a summing element S, the voltage from the unit V2 being first shifted in phase by 90 degrees. The output from the elements S is independent of the azimuth of the incoming waves, and is fed to one input of a comparator K<SP>1</SP>. In the embodiment shown in Fig. 4, a common processing unit V3 is used for the signals from the aerials R3/R4 and from the aerial H, which are connected thereto in alternating sequence by a switch U under the control of a multi-vibrator M. In the one position of the switch U a voltage due to the signal from the aerials R3/R4 is compared with the output voltage from the summing element S. If the amplitude of the signal from the aerials R3/R4 is sufficiently less than that of the combined signals from the aerials R1, R2, an electronic switch W is operated, and so biases the control grid G of the CRT as to brighten the display. In the other position of the switch U a voltage due to the signal from the sense aerial H is connected through directly to the control grid G of the CRT. It can only be effective if the switch W triggers said grid, and with suitably selected switch times the half of the CRT image which corresponds to the (incorrect) azimuth offset by 180 degrees appears substantially darker. In another embodiment (Fig. 3, not shown) separate processing units are provided for the signals from the aerials R3/R4 and H. The output from the processing unit associated with the aerial H is coupled through a capacitor to the control grid of the CRT. In another embodiment (Fig. 2, not shown) the sense aerial is omitted.

Abstract: 592,792. Pulse generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 16, 1944, No. 4950. Convention date, July 30, 1942. [Class 40 (v)] In a multivibrator circuit the grid of one valve 27, in addition to being supplied with control signals, is connected over a time constant-circuit, comprising a resistance 51 in series with a condenser 49, to the anode of the other valve 27<1>, the grid of the latter being connected over resistances 45, 47 to the discharge path of the first valve 27. The grid resistance 37 of valve 27 is returned to the cathode so that the valve normally passes current, biassing valve 271 beyond cut-off due to the potential drop over cathode resistance 41. A negative triggering pulse, applied to the grid, cuts off valve 27, the rise in anode potential causing valve 27<1> to conduct. The fall in anode potential of valve 27<1> is fed back over condenser 49 and resistance 51 to maintain valve 27 cut-off until condenser 49 discharges sufficiently to allow the grid potential to rise to a value where anode current flows, decreasing the current in valve 27<1>, with the result that the circuit returns to its normal state. The waveforms of the generated pulses at the anodes of the valves change slowly throughout their length, Fig. 2 (not shown) and it is stated that by combining with the cathode potential by means of resistances 63, 65 and 59, 61 more rectangular pulses may be obtained. The input condenser 23 may be small for pulse operation or large or replaced by a D.C. source if low frequency operation is required. The resistance 41 may be shunted by a condenser or replaced by a battery.
