Title: Improvements in or relating to automatic flow regulating valves
IPC: G05D16/10
Filed: 1946-08-13
Abstract: 630,968. Fluid-actuated valves ; hydraulic transmission of power. SHIELDS, R. (Vickers Inc.). Aug. 13. 1946, No. 23919. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 29, 1946.] [Classes 69 (ii) and 135] In order to facilitate the mass production of several types of flow-regiilating valves, in which a pressure compensating valve controlled by the pressure drop across an adjustable throttle maintains constant the flow through the throttle, a basic design of valve body is adapted to be used without modifications or with the addition of various bores and passages in the manufacture of the several types of valve. The basic designs of valve body, 42, Fig. 1, is provided with two external ports 56, 60 respectively, connected to the exhaust of a hydraulic motor 26 and an oil reservoir 12, and the liquid flow between these ports is regulated by a piston valve 92 integral with an actuating piston 84 the faces of which are subjected through passages 82, 52 to the pressures on each side of a manually adjustable throttle valve 63, and thus the piston valve 92 functions to prevent the rate of flow of the exhaust liquid and therefore the speed of the motor exceeding the value determined by the setting of the throttle valve. The basic design may be modified by the addition of a bore 168, Fig. 5, accommodating a non-return valve 174 and a passage 135<SP>1</SP>, thus providing an alternative fluid path between the port 56, communicating with one end of the motor, and the port 60 which may be connected by a valve 20 either to the reservoir 12 or to a pump 10. When the port 60 is connected to the reservoir the flow of exhaust fluid from the motor is regulated by the valve 92, but when the port 60 is connected to the pump, pressure fluid passes through the non-return valve and gives a quick-return movement to the motor. In a modification the basic valve body is provided with an inlet passage 128, Fig. 4, connected to the pump 10 and communicating through the adjustable throttle with the port 601, a passage 135 communicating with a chamber 95 enclosed by the piston 84<SP>1</SP>, and a bore 132, one end of which communicates with the port 56<SP>1</SP> and the other with the passage 135. The ports 561, 601 are respectively connected to the reservoir 12 and one end of the motor 26 and a pilot relief valve 142 is mounted in the bore 132. In operation when the flow from the pump across the throttle to the motor becomes excessive, the pressures on each side of the throttle acting on opposite faces of the piston 841 move the piston and actuate a piston valve 901 which byepasses the excess fluid through the port 56<SP>1</SP> to the reservoir. The pilot valve 142 is adapted to be opened by excessive fluid pressure in the system to suddenly exhaust the chamber 95, thus causing the unbalanced pressure on the piston 84<SP>1</SP> to move the piston and to open the valve 901. Specification 399,609 is referred to.

Filed: 1971-04-19
Abstract: 1344935 Feeding sheets JAGENBERGWERKE AG 19 April 1971 [2 March 1970] 23920/71 Heading B8R In apparatus for mutually aligning the edges of folded side portions of a rectangular tubular box blank of cardboard or the like, provided with a longitudinal adhesive seam as seen in the feed direction, the blanks 1, 1<SP>1</SP> are conveyed successively up to a fixed stop 2 which projects into the feed path and is arranged immediately above a downwardly displaceable conveyer belt section 17, the front ends of the side portions of the blank being urged against the stop thereby aligning the edges, and a plunger 3 being operable to move each blank, supported on the conveyer section 17, downwardly out of the path of the stop. A folded blank 1 is fed via conveyer belts 21, 22 and belt 17 to the stop 2, a succeeding blank 1<SP>1</SP> actuating feeler 23 which causes the plunger of motor 10 to descend pivoting a gear segment 5 about its pivot point 24 and thereby rotating a pair of rollers 4 which are driven by segment 5 via a freewheel device. This downward movement also allows the freely rotating rollers 4 to descend so that a roller engages each side portion urging each against the stop 2 and thereby aligning them. The rollers are then raised, when feeler 25 is actuated, and motor 14 is activated to lower the plunger 3 which forces the blank 1 and its supporting conveyer belt 17 below the stop 2, the blank thus being fed onwards. The plunger may be pivotable about point 27 so that it remains in engagement with the blank for part of its movement past the stop 2.

Title: A rotary-piston internal combustion engine with rotating distributor
IPC: F02B53/00
Filed: 1962-06-25
Abstract: 1,006,798. Rotary-piston internal combustion engines. REGIE NATIONALE DES USINES RENAULT. June 25, 1962 [June 29, 1961; June 30, 1961], No. 24391/62. Heading F1F. A rotary-piston I.C. engine comprising an N+1-lobed stator and an N-lobed epicycloidal piston eccentrically rotatable therein, includes on at least one side of the piston an end plate secured to and rotatable with the piston which extends beyond the periphery of the epicyloid and is formed with ports beyond the piston profile to admit and exhaust the working gases to and from the working chambers of the engine. As shown in Figs. 1 and 2, a piston 1 formed by a hub portion 12 and a body portion 13 and flanked by end plates 5, 6 is eccentrically mounted on a crank-shaft 16 in a stator formed by a central portion 2, end portions 3, 4 and a front cover 7 which includes an inlet conduit 28 communicating with radial passages 24 in a rotatable member 23 which includes an eccentric balance weight 25. The plate 6, Fig. 3, is formed with admission ports 41, 42 and the plate 5, Fig. 4, with exhaust ports 45, 46 which open into communication with an exhaust conduit 30. Both sets of ports are similarly shaped, the inlet ports opening slowly and closing abruptly to give good filling of combustion mixture whilst the exhaust ports open rapidly and close slowly. As shown in Fig. 1, the end plates 5, 6 have substantial thickness and include cavities 34, 35 through which cooling oil may circulate. The stator portions 2, 3, include cavities 32, 31 for the circulation of cooling water and the piston 1, cavities 33 for the circulation of cooling oil. Working chambers 8, five in number, each include a combustion chamber 9 fitted with a spark-plug 60. On each rotation of the piston each chamber in turn is connected twice to an inlet port and twice to an exhause port and since the crank-shaft rotates at four times the speed of the rotor the engine is equivalent to a conventional five cylinder engine. At top dead-centre, Fig. 9, both inlet and exhaust ports A, E communicate with the combustion chamber to produce a slight scavenging action. Radially disposed sealing strips 36 extending the length of the piston are housed in stator grooves located between adjacent working chambers, sealing strips 37, 38 following the profile of the stator lobes in the stator portion 2 and scaling strips 39, 40 on the plates 5, 6. In a modification, both the inlet and exhaust ports are located in the end plate 6, the end plate 5 then being relatively thin with cooling cavities omitted. In another modification, both the end plates may be made relatively thin. A fly-wheel 21 including a balance weight 22 is fitted on one end of the crank-shaft 16 and a pinion 26 on the other end in mesh with another pinion 27 to drive engine auxiliaries. In a modification, Figs. 16 and 17 (not shown), an end-plate which includes both the inlet and exhaust ports is linked to the piston to rotate at the same speed as the piston by a plurality of eccentrically disposed pins.

Title: Improvements relating to Nuclear Magnetic Resonance Spectroscopy.
Inventor: PARKER LESLIE KEARTON
IPC: G01R33/46
Filed: 1966-06-01
Abstract: 1,191,455. N.M.R. spectrometers. PERKINELMER Ltd. Aug. 16, 1967 [June 1, 1966], No. 24396/66. Heading G1N. In an N.M.R. spectrometer, spin-coupled gyromagnetic nuclei are discoupled by subjecting the sample to decoupling R. F. power which is arranged to saturate all resonances over a conventionally wide region of the N. M. R. spectrum while leaving unaffected a middle zone or "quiet slot" extending between convenient limits equidistant from the position on the spectrum corresponding to the frequency of the normal R. F. power applied to the sample, whereby as the sample is scanned in either the frequency scan or field scan mode the "quiet slot" flanked by saturated zones travels along the horizontal axis of the spectrum to enable a resonance occuring in a chemical group of the N.M.R. sample to be observed substantially free from spin coupling as the mid-point of the "quiet slot" approaches the chemical shift at which said resonance occurs. Three alternative embodiments are described with reference to Fig. 1, in which circuits A, B, C are respectively connected to point P. In one embodiment, a series of blocking oscillators 1 and a weighting network 2 provide signals at spot frequencies of 15, 20, 25, 30 and 35 c/s of substantially equal amplitude which modulate through a suppressed-carrier modulator 3, 60 Mc/s power from source 4 forming part of an N.M.R. spectrometer comprising also a sample probe 7, alternators 6, 8 and a buffer amplifier 5. The arrangement is such that only the first-order sideband pair from each blocking oscillator is effective. The width of the "quiet slot" is adjustable by 5 c/s steps by switching on or off the appropriate blocking oscillators. In a second embodiment, a 5 c/s oscillator 9 and a harmonic generator 10 are used. In a third embodiment, a 300 c/s white noise band from 9À7 kc/s to 10 kc/s modulates the output of a 10 kc/s oscillator 13 through a suppressed-carrier modulator 14 and a low pass filter 15 passes only the 0-300 c/s sideband. An adjustable means 16 for increasing the frequency of oscillator 13 by an amount from 0 to 50 c/s provides a "quiet slot" of continuously adjustable width. The sample may contain an internal reference having a large chemical shift, e.g. trimethylsilane (T. M. S.) and the N.M.R. spectrum may be scanned between the limits of the chemical shift of a bare proton and the chemical shift of T. M.S.

Title: Method of and apparatus for continuous counter current liquid/liquid extractions
Inventor: LOHR KARL-HEINZ EISEN
IPC: B01J21/00
Filed: 1951-10-19
Abstract: 696,114. Making extracts. METALLGES., AKT.-GES. Oct. 19, 1951, No. 24491/51. Class 81 (i). In a method of continuous countercurrent liquid/liquid extraction in a plurality of stages, the mixing and conveying of the liquids is effected by centrifugal pumps which are disposed in separate pump spaces in individual chambers of the extractor corresponding to the stages. Preferably centrifugal pumps having a flat characteristic curve are used so that a small variation in the liquid level in the pump space leads to a large variation in the quantity delivered. As shown in Fig. 1, the heavier liquid enters stage a at 4 and passes up a pipe 5, over a weir 6, into a pump space 30 from whence it is pumped in admixture with the lighter liquid through tubes 12 and 13 into chamber 14 and thence to separating chamber 33. In a similar manner it is passed through stages band c finally leaving the apparatus through an overflow 21 and pipe 22. The lighter liquid is led through the conduit 7 into the pump space 32 of the stage c where it is mixed with the heavier liquid. The mixture is raised from the chamber 32 by a pump 11 and passes through pipes 12 and 13 into the distributing chamber 14 and separating chamber 35 of the stage c. The light layer flows through the funnel (not shown in Fig. 1) of the stage c into pump space 31 of stage b. It is then passed in similar manner through stages band a. From stage a the lighter separating layer leaves the apparatus through an overflow 16. In the event of failure of the pump in the intermediate stage b, two layers are formed in the corresponding pump space 31. The liquid in the lower stratum is passed through the inclined tube 24 into the pump space 32 of the stage c. The upper layer flows through a pipe 25 into the pump space 30 of the stage a. According to another modification (Fig. 4) the individual extraction stages are formed to represent sectors of a circle when seen in plan. Each centrifugal pump 54, disposed in a cylindrical pump space 53, draws heavy liquid from the bottom circumferential part of the corresponding settling chamber through a riser pipe 55 and lighter liquid from the top of the circumferential part of the next but one settling chamber through a line 56 and pumps the mixture through a line 58 to the central part of the next settling chamber. As the liquids pass from the centre to the circumference of each chamber, separation increases by virtue of the decrease in velocity of flow.

Abstract: 1433177 Counting apparatus; liquid dispensers KIENZLE APPARATE GmbH 23 May 1973 [1 July 1972] 24656/73 Heading G4D The invention concerns an arrangement for use in petrol dispensers of the kind including two counters for registering volume dispensed and total price and a variable gearing between the counters which can be preset according to the unit price, the arrangement enabling the dispenser to deal with higher prices than can be set on the conventional apparatus. As usual the dispenser has a pump 1 and flow meter 2 which drives a shaft 35 to record the volume dispensed on a counter 36 and through a variator 13, a second shaft 32 coupled to a price counter 37. The variator includes a cone gear 13 and three sets of pick up gears 14-16 which can each be set to any one of ten positions on the cone gear according to a three figure number set up on dials 17-22. The outputs of the three gears 14-16 are added at 29 so that shaft 32 is rotated in proportion to the product of volume and the three figure number. If the unit price exceeds the maximum three figure number the most significant digit cannot be set. Accordingly in the present arrangement shaft 32 is coupled to the price counter 37 through a differential gearing 53-57 and its third shaft is driven through additional gearing from "volume" shaft 35 so as to add to the counter 37 a contribution for the most significant digit. To enable the extra digit to be changed from 1 back to 0 the additional gearing can be disengaged and the third shaft of the differential locked (by pin 66) by rotating a cam 69 to tilt a lever 65. The cam 69 is coupled by wires 77 to rotate sectors 79 located alongside the three digits of the unit price indicator 40 to indicate the respective digit. If necessary a second set of additional gearing can be fitted, tilting of lever 65 selecting one or the other, the sectors 79 then being marked to show two non-zero digits. The dispenser is provided with totalizing counters 38, 39 and means 5 for resetting the main counters 36, 37 to zero, clutches 43 being disengaged automatically when the dispensing nozzle is hung up.

Title: A process for improving wool
IPC: D06M13/21
Filed: 1933-09-06
Abstract: Wool, which has been washed to remove grease, is subjected to a mild treatment insufficient to affect its dyeing properties with fatty acids or halogen-substituted fatty acids containing up to 5 carbon atoms in the molecule, or with the anhydrides of such acids, in all cases substantially in the absence of water.  Wool, cardings or yarn, spun, knitted or woven in the raw, bleached or dyed condition may be used.  Suitable acids which are specified are formic, acetic, and chlorinated acetic acids, and acetic, propionic and chlorinated acetic anhydrides, and the acids may be employed in a liquid form, but preferably in organic solvents, e.g. benzene, and carbon tetrachloride avoiding solvents containing oxygen.  The material may be soaked in the solution, dried and aerated, or may be treated with the reagent in gaseous form, or a combination of these methods may be employed, and the treatment may be combined with a water-proofing treatment by the action of anhydrides of higher fatty acids. According to examples: (1) German shearing wool previously washed is treated with a solution of formic acid in benzene, dried and aerated; raw carded yarn is similarly treated; (2) acid dyed carded yarn is treated with a solution of glacial acetic acid in benzene, followed by drying and aerating; (3) raw carded yarn is treated with formic acid in carbon tetrachloride or, trichloracetic acid in benzene; (4) raw carded yarn is treated with acetic anhydride in benzene; acid dyed cloth is similarly treated; (5) dyed carded yarn is exposed to formic acid vapour followed by aeration or neutralization with ammonia; (6) washed carded wool in flock or undyed form is similarly treated.
