Title: Fluid control valve units
Inventor: HALL ERNEST STANLEY
IPC: G05D7/01
Filed: 1954-11-29
Abstract: 816,671. Fluid-actuated valves. HOBOURNEATON MANUFACTURING CO. Ltd. Oct. 13, 1955 [Nov. 29, 1954], No. 34506/54. Class 135. A fluid control unit adapted to be connected to the suction and delivery passages of a pump and also to a closed loop circuit comprises a valve body or casing 1 having a valve chamber 2 in which are arranged two telescopically related hollow valve members 9, 10A, the outer one, 9, functioning as a flow control member and opening against a spring 14 to by-pass fluid from the pump delivery back to the pump suction through an annular passage 5 when the pressure drop across a flow control orifice exceeds a predetermined value, and the other hollow valve l0A functioning as a relief valve and opening against a spring 15 to pass fluid out through ports 13 and the chamber 5 when the pressure in the closed loop circuit exceeds a predetermined value. The pump delivery is connected through the threaded boss 4 to an annular chamber 3 and the closed loop circuit is connected to the chamber 2 through a union 8. As shown in Fig. 3, the flow control orifice is formed as a restricted orifice 21 in the valve member 10A. It may, however, be formed as a number of small radial holes in the valve member 9 in place of the ports 22. The outer or left-hand end of the valve member 10A is of slightly larger diameter than the inner end. The valve member 10A abuts a spring-retaining ring 16 when closed. The collar 19 on the valve member 9 and the annular chamber 20 form a dashpot to which the fluid has a restricted access. In another arrangement the valve member 10A has ends of appreciably different diameter, the loading spring 15 acting on the smaller area and also on a flanged ring which maintains a fixed throttling rod in place. The rod has a conical end which co-operates with one end of the passage through the valve member 10A.

Title: Pattern inspection apparatus
IPC: G06V10/88
Filed: 1973-07-20
Abstract: 1397903 Pattern recognition systems SPERRY RAND CORP 20 July 1973 [27 July 1972] 34608/73 Heading G4R A pattern, e.g. fingerprint, recognition apparatus comprises a rotating grating formed of parallel transparent and reflective or absorptive lines. An image of the grating is reflected back on to itself such that photosensors viewing the grating receive no light. When a pattern is placed adjacent the reflecting surface the lines of the pattern diffract the light returned to the grating. The diffracted light is sensed by the photosensors, each photosensor output varying cyclically and having a maximum value when the lines of the corresponding area of the pattern are parallel to the grating lines. Signals indicative of the instants of occurrence of the maxima, or alternatively the minima, are compared with reference signals to identify the pattern.  In one arrangement, Fig. 1, light from a non- coherent source 10 is directed to grating 15 and passes via lens 17 to mirror 18. The reflected image is superimposed on the grating such that the light lines of the image fall on the opaque lines of the grating. Consequently no light passes via the grating and mirror 12 to the photosensors 19. If a transparency 21 of the pattern or fingerprint to be identified is placed as shown the pattern will diffract light. For example, in the case of area 21e of the pattern, diffraction will spread the light sideways so that now light will fall on the photo-cell 19e. On the other hand area 21a diffracts light vertically so the diffracted light from this area will still be blocked by the vertical grating lines. As the grating rotates through 90 degrees the output of photosensor 19e falls to a minimum while that of 19a rises to its maximum. The instant of occurrence of the maximum (or minimum) If each photosensor is detected and at that instant the count on a counter, incremented by clock pulses derived by sensing notches 28 on the grating carrier, is gated in to a respective store. The contents of the stores are correlated with stored counts derived from known patterns in a similar manner in order to identify the pattern. In another arrangement (Fig. 2, not shown), the photosensors are on the same side of the grating as the pattern. The pattern may in this case be that of a finger placed on one face of a reflecting prism. In a third arrangement (Fig. 3, not shown), the light source is on the same side of the grating as the reflecting prism. The gratings in these arrangements lie off the axis of rotation.

Abstract: 1,227,880. 880. Photo-electric edge followers. COMPAGNIE D'ETUDES ET DE REALISATIONS DE CYBERNETIQUE INDUSTRIELLE. July 19, 1968 [July 27, 1967] No.34651/68. Heading G1A. [Also in Division G3] Apparatus for following a boundary between light and dark comprises a television camera scanning across the boundary, means for measuring the durations of the light portions of at least two line scans, a motor rotating the camera until the deviations are equal and traversing motors driving the camera along the boundary. The camera 16 is mounted in a scanning head 5 for rotation by a step-by-step motor 15, Fig. 4, through a pulley band 17. Offset of the line tracing is provided by a screw 19 which shifts the camera axis Z<SP>1</SP> Z<SP>1</SP> relative to the axis of rotation ZZ. Potentiometers 21, 22 generate Œ sin # and Œ cos # signals where # is the angle of the axis 23 of the camera field relative to the X co-ordinate drive of the scanning head. | cos#| and | sin#| signals are applied to amplitude/frequency converters 26, 27 Fig. 5 by diodes which pass whichever of the Œ cos# and Œ sin# signals is positive. The converters 26, 27 respectively produce pulse trains of frequency 2,000 cos# Hz and 2,000 sin# Hz which are applied to the traversing motors Mx, My in senses determined by the signs of the + cos# and + sin# signals. The camera video signals a, b, c corresponding to the lines A B C, Fig. 6, are fed to comparators 24, 25. So long as the video signals indicate that the boundary coincides with a predetermined axis 23 of the camera tracing continues, but when the a or b signal has too long or short a "light" portion, a signal from comparator 24 switches the pulses from converters 26, 27 via frequency dividers 41, 42 to reduce the tracing speed. When signal c has too long or short a light portion a signal from comparator 25 stops motors Mx and My and transfers the frequency divided pulses to the motor 15 (M # ) to rotate the camera until the boundary coincides with the axis 23. A flip-flop set by the start of a line scan and re-set by the boundary may provide an artificial "light" portion for the video signal to cope with re-entrant curves. The line follower may be used for controlling or making a control tape for machine tools or planimetry. A relay reverses the connections to motors M # , Mx and My to cope with internal and external machining.

A cathodic protection anode having a centred, blind, non-circular hole therein (so that it can grip a removal tool) is screwed into a plug, with a centered hole, which is screwed into a threaded plug bore in a fluid holding vessel. The hole in the anode penetrates thereinto to such an extent that depletion of the anode will open it to create an escape path for a depletion-signalling leakage stream, the appearance of which indicates that the anode must be changed, the removal of the residue from the plug being accomplished by a wrench using the non-circular hole. In an example the vessel is of Al, the cover into which the plug is screwed is of gray cast iron, the plug is of brass and the anode of zinc.

Title: Improvements in and relating to the destructive hydrogenation of carbonaceous materials
IPC: C10G1/08
Filed: 1934-12-04
Abstract: In processes for the treatment of distillable carbonaceous materials with hydrogenating gases in which corrosion of the apparatus by halogens or their compounds added or formed during the reaction is prevented by treating the halogens with a compound of an alkali or alkaline earth metal to form a stable halide, e.g. as described in Specification 432,958, the stable halide is decomposed by treatment with inorganic acids or the ammonium salts of said acids to form ammonium or hydrogen halide which is returned to the process either in conjunction with the initial materials or separately.  Ammonium sulphate or sulphuric acid obtained from acid sludge is preferably used and may be added in an amount 50 per cent in excess of that required to decompose the halide.  A paste of 50 per cent bituminous coal and 50 per cent heavy oil to which 0.4 per cent chlorine in the form of ammonium chloride is added, is destructively hydrogenated in a continuous process.  The chlorine in the vapours leaving the hot catch pot is absorbed in a second catch pot by treatment with a suspension of lime in heavy oil as described in Specification 432,958.  The ammonium chloride is then left out of the paste and the equivalent amount of chlorine provided by recirculating oil and calcium chloride obtained from the second catch pot together with ammonium sulphate in the form of a saturated solution obtained by neutralizing acid tar with aqueous ammonia.

Title: Improvements in electrical signalling systems employing highfrequency carrier waves
IPC: H04J1/14
Filed: 1922-12-28
Abstract: 208,390. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 28, 1922. Addition to 170,286 and 196,123. Multiplex signalling; wired wire. less systems; calling systems and apparatus.-In a multiplex system wherein a signalling device associated with one end of a transmission line is operated in response to the interruption of normallyapplied carrier-wave oscillations at the other end of the line, as described in the parent Specifications, the signal-controlling means is only operated if the interruption of the oscillations takes place intermittently at a predetermined late, so that in the event of the complete failure or breakdown of any one of the carrier frequencies in the system, the transmission of a false ringing signal is prevented. The Figure shows part of a system in which low-frequency stations A which may be subscribers' lines or ordinary telephone exchanges are associated through a two-way carrier channel 1 with a carrier-wave transmission line ML. Normally, continuous oscillations from a generator O, passing through a modulator M and a band filter MBF1, are transmitted over the line ML to a receiving channel at the distant end of the line, where after passing through a filter DBF1, detector D and amplifier RA, the unmodulated component is selected by a filter HPF and, by means of a detector SD, operates a relay 14. When transmitting a calling signal, the application of ringing-current to the line 3 intermittently energizes relay 10 which at each energization short-circuits the oscillator O thus producing an intermittent Interruption of the carrier waves in the line ML which causes the relay 14 to oscillate its armature. A relay 17 energized over either front or back contacts of relay 14, is made relatively slow to energize and quick to release so that, in response to the intermittent operation of relay 14, it will de-energize, but in response to a single de-energization of relay 14 due to a failure in the carrier-wave it will remain energized. The de-energization of relay 17 causes the lighting of a signal lamp 19, the operation of relay 4 to connect the low-frequency signalling source 23 to the line 3, and the operation of a relay 13 which short-circuits the input of the modulator M to prevent singing due to the unbalancing of transformer 5 and opens the circuit of relay 10 to prevent station A from initiating a call: In multiplex working, the different frequencies used for transmission and reception at one end of the line ML may either be arranged in separate groups over different frequency ranges, or the frequencies used for transmission may alternate with those used for reception.
