Abstract: 717,615. Filters. TISCHER, E. M. March 28, 1952, No. 8015/52. Class 46 Filtering apparatus comprising a casing containing a perforate drum with a plurality of turns of a strip of filter fabric wound thereon is characterized in that the filter drum is formed with a plurality of narrow annular surfaces very closely spaced in the axial direction, supporting the strip, the width of the strip and the tension under which it is wound being such that the turns or layers are pressed against each other with uniform pressure throughout the-length of the strip. A drum 5, Fig. 1, has wound upon it a strip 6, of fabric woven from metal wire or from nylon or perlon fibre, in a number of superimposed turns. Annular flanges 10 are provided on the drum ends and annular gaps 7 are cut in its surface. The starting end of the strip 6 is brazed or cemented to the drum 5 and the free end brazed or cemented to the penultimate turn. The drum rests by a dished end wall 17 on an outlet boss 18 and above it is disposed a perforate differential piston 15 loaded by a spring 14 which yields under excess inlet pressure to permit bye-passing of liquid through a gap 16 then formed between the piston 15 and the end of the drum 5. In Fig. 4 several filter elements are arranged one above another in a casing 23, each element comprising two members 25, 26 meeting at 24 and having mounted concentrically upon them a number of filter drums 27 to 29 (shown diagrammatically) each having a filter strip 6 wound upon it. In all cases uniform pressure of the turns is ensured by using a narrow strip. Where the drum diameter is 40 mm or less the width of the strip is made approximately equal to it; where the diameter is greater the width of the strip is less that that diameter (see Fig. 4). The winding tension may be from one to three kilogrammes per cm. of strip width. It is stated that five turns of strip of 100 Á mesh size provides a " filtering fineness " of from 5 to 10 Á.

Title: Dynamic gas blending
IPC: B01F23/10
Filed: 1974-02-22
Abstract: 1449929 Mixing gases in proportions SCOTT ENVIRONMENTAL TECHNOLOGY INC 22 Feb 1974 [22 Feb 1973 26 Oct 1973] 8231/74 Heading B1C [Also in Division G3] Components of a gaseous mixture are mixed in a low pressure zone and then compressed. The composition of the high pressure mixture is monitored and compared with a predetermined composition to form a signal which is used to adjust the feed of gas to the low pressure zone. The mixture is subsequently fed to a high pressure storage vessel.  As shown, storage vessels 27a-d are to be charged with gases used as standards in exhaust pollution measurement at pressures which are so high that the components will not mix freely. The required active gas from a selected supply vessel 10 is fed to a low pressure mixing chamber 23 together with nitrogen 11 or air 13. The mixture passes to an oil-free compressor 25 connected by a high pressure conduit 26 with the appropriate storage vessel 27a-d. A sample of the compressed mixture flows through a selector valve 32 to an infra-red gas analyser 30 in which the concentration of the active gas is compared with a reference value obtained by previously feeding through valve 32 a sample of gas already in the storage vessel 27a-d or a standard sample from a valve 36. An output signal from the analyser 30 controls a servomotor 53 which adjusts a gas flow control valve 20. The analyser 30 may include a double beam measuring arrangement operating in a null balance mode, Figs. 2 - 3 (not shown).

Title: Improvements in or relating to piezo-electric devices
IPC: H03B5/34
Filed: 1928-03-20
Abstract: 287,484. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Peterson, H. 0.). March 21, 1927, [Convention date]. Thermionic generators.- The degree of control exercised by a piezo-electric crystal on a valve oscillator is improved by providing a variable condenser for neutralizing the inter-electrode capacity of the valve. As shown in Fig. 2, neutralizing is effected by a divided plate coil 11, with its free end connected through a variable condenser 17 to the grid. The plate-grid capacity may be supplemented by a variable condenser 14, and a further variable condenser 15 is connected between the free end of the plate coil 11 and the filament. The crystal 16 is connected as a shunt to the condenser 17. Either the plate coil 11, or the grid coil 12, as shown, may be tuned by a variable condenser 13. In a modification, Fig. 1 (not shown), the grid coil is centre-tapped and its free end connected to the plate through a balancing condenser shunted by the crystal. The tuning-condenser and the balancing-condenser may be shunted by gaps or other devices for protection against high voltages, Fig. 5 (not shown), and resistances may be connected in series with the gaps. In a further modification, shown in Fig. 4, the plate is connected to the filament by two branched circuits each comprising a, small variable condenser 14, 15 and a coil 12<a>, 12b coupled to the tuned gril coil 12. The crystal 16 is in shunt to the condenser 15.

Title: Improvements in or relating to the braking of tractor and trailer vehicles
Inventor: EDGE STANLEY HOWARD
IPC: B60T13/36
Filed: 1950-04-04
Abstract: 667,736. Brakes for tractor-trailer vehicles. CLAYTON DEWANDRE CO., Ltd. April 4, 1950. No. 8468/50. Class 103 (i). A control valve mechanism for compressed air braking systems of tractor and trailer vehicles including a, main valve which, upon operation of a brake actuator, admits compressed air through a direct connection to the trailer brakes, and through a delay valve to the tractor brakes is characterized in that the delay valve includes a movable component formed with at least one restricted orifice and normally held against a seating by spring pressure, whereby under normal conditions of brake application air flows gradually through the orifice to the tractor brakes. but under emergency conditions the valve component is unseated to permit a more rapid air-flow to the tractor brakes, to ensure that the trailer brakes operate before those on the tractor. As shown, the supply of compressed air from a port 2 in the casing of the main valve A is controlled by a valve 12 operated by a piston 6 connected to the brake pedal, the air passing through a conduit 18 to the delay valve B communicating by ports 24, 32 with the trailer and tractor brakes respectively. The piston 6 is spaced from a second piston 8 by a compression spring 7, the piston 8 being slidable in a baffle member 16 and engageable with a disc valve 10 mounted on the stem of the valve 12. A port 17 in the member 16 ensures that while a reaction pressure is exerted on the piston 8, the latter is prevented from being forced backwards by the sudden admission of compressed air when the valve 12 is opened. There is direct communication between the conduit 18 and trailer brake port 24, by a delay valve 26 is fitted between the conduit 18 and tractor brake port 32. The valve 26 and an annular disc 28, which engages a seating 30, are pressed into engagement by a spring 29. An orifice 27 is provided in the valve 26. During a normal brake application air admitted by the valve 12 passes directly to the trailer brakes through port 24, and maintains the disc 28 in contact with the seating 30, so that there is delayed admission of air to the tractor brakes through the orifice 27. On making a rapid brake application the pressure built up in the valve chamber overcomes the load imposed by the spring 28 and lifts the members 26, 28 from the seating 30, so that a more rapid admission of air to the tractor brakes occurs, although the trailer brakes are still applied first.

Abstract: 710,806. Speed governors. BOSCH GES., R. April 3, 1952 [April 4, 1951], No. 8515/52. Class 57.- In a speed governor for an internal combustion engine, the control member 1 of the fuel-injection pump is actuated by a spring-loaded diaphragm &c. 3 exposed to the pressure in the air manifold 15 between the throttle valve 16 and the engine, and a rotary valve 11 driven by the engine is provided to establish this connection during the periods that the engine pistons are making 'an induction stroke. Fig. 3 shows an arrangement in which the valve is in the form of segments 17 that are pivoted at 30 and move outwardly under centrifugal force so that the valve is operative at high engine speeds and inoperative at lower speeds, whilst at lowest speeds a disc 35 is moved into the opening 43 to throttle the connection between the manifold 15 and the chamber 4. The speed at which the segments i 7 move is controlled by a spring 36 adjustable by a cam 38. The throttle valve may be loaded by a spring against an abutment on the manual adjustment lever, the strength of the spring being such that it permits the valve to move towards its closed position when the pressure falls below that necessary to maintain the control member 1 in its stop position.

Abstract: 1,166,892. Correlation techniques. PERKIN-ELMER CORP. Feb. 23, 1967 [Feb. 24, 1966], No. 8751/67. Heading G1U. [Also in Divisions G2 and H4] An optical correlator for determing the correlation of two electrical signals comprises a source of monochromatic coherent light, an ultrasonic light modulator having two ultrasonic delay lines for receipt of the two electrical signals, and a light-sensitive detector for detecting the intensity of the light beam after diffraction in the two delay lines, and thus for detecting the correlation of the two signals. As shown in Fig. 1 a beam of coherent light produced by a laser 11 is focused on an aperture 21 in a diaphragm 13 by a condensing lens 12 and is then passed through a collimator 14 to a light modulator 15 (see Division H4). Some of the incident light is diffracted by a train of sound waves produced by an ultrasonic transducer 25 controlled by an incoming signal source 34 and the beam is then passed through a lens system 16 which forms the Fourier transform of the incident light in its back focal plane at which is placed an apertured mirror 17. The unmodulated light passes through a hole 36 in the mirror and the diffracted component is passed back through the lens 16 to the right modulator 15 where it passes through and is diffracted by a train of sound waves produced by a second ultrasonic transducer 26 supplied by a reference signal source 35. The diffracted light is then integrated by the lens 14 which forms the correlation integral of the electrical signals produced in the sources 34, 35 at its focal plane at which is situated a correlation detector 19, a photo-multiplier. The light is reflected to the correlation detector by a mirror 18 which also serves to shade the lower halves of the lens system 14 and the light modulator 15 from the unmodulated beam produced by the laser 11. In a modification Fig. 5 (not shown) the collimator is omitted. In a further modification Fig. 6 (not shown) including both a collimator and Fourier transform lens, the ultrasonic transducers are placed opposite one another so that the light beam passes through both delay lines at the same time. The diffracted light is then passed through an integrating lens (78) which forms the correlation integral of the two electrical signals. A correlation detector is placed at the back focal plane of this lens but slightly off the optical axis so that it receives only the diffracted component of the light beam.

Abstract: 1,049,441. Cooling systems for internal combustion engines. HUMBER Ltd. March 5, 1963 [March 13, 1962], No. 8758/63. Heading F4U. In a vehicle engine cooling system which comprises a radiator 10, a cooling jacket for the engine 15, and an engine driven pump 16 which delivers coolant into the cooling jacket of the radiator, the cooling system is sealed and includes an air cushion which may either be such as indicated at 21 in the upper header of the radiator in contact with the coolant in which case the air-coolant ratio is between 1 : 3 and 1 : 4, or alternatively it may be in a separate communicating compartment 30, in which case the air is at a lower temperature than the coolant and the air-coolant ratio in the system is 1 : 10. A filler tube (not shown) for the system may be transparent to function as a sight glass for the liquid level and may contain also a diaphragm arranged to burst at a safe pressure above the normal maximum. The invention is said to obviate the need for the usual pressure release valve. The system may incorporate a thermostatically controlled bypass and a heat exchanger for heating the vehicle space.
