Patent GB-976663-A (GB)
Title: Improved method and means for measuring the concentration of suspended particles in aliquid
Inventor: JOHNSTON ROY HARRY WILLIAM
IPC: G01N15/02
Filed: 1961-11-02
Abstract: 976,663. Examining solutions photoelectronically. ARTHUR GUINNESS SON & CO. (PARK ROYAL) Ltd. Oct. 24,1962 [Nov. 2, 1961], No. 39238/61. Heading G1A. The invention relates to a method of, and apparatus for measuring the cencentration of suspended solid particles in a liquid which comprises illuminating the liquid with a focussed beam of light and detecting light scattered from the liquid at an angle greater than 90 degrees to forward direction of the incident beam, by means which converts the amount of light scattered into an electrical current. In an embodiment described light from a source is focused by a lens or lens system on to the surface of the liquid at right-angles thereto and light scattered from the liquid at an angle of between 130 degrees-155 degrees to the forward direction of incident beam is collected by an optical system which includes a photomultiplier the output current of which gives a measure of the concentration of particles in the liquid. It is preferred to circulate the liquid through a transparent tube by means of a pump whose speed can be controlled in such a way as to avoid decompressions of the fluid which might give rise to buble formation. The alternating component of the signal from the photomultiplier, arising from fluctuations in scattered light intensity due to the flow of clumps of particles through the liquid may be analysed in amplitude and frequency, to give information as to the degree of flocculence or aggregation of the suspended solids.

Title: An Improved Machine for Forming and Filling Bags such as Tea-Bags
IPC: B21C1/22
Filed: 1966-09-12
Abstract: 1,164,481. Making bags; cutting webs. IMA S.p.A. 12 Sept., 1966 [10 Sept., 1965], No. 40582/66. Headings B4B and B5D. [Also in Division B8] A machine for forming, filling and closing tea-bags has an equi-angular 12-arm rotary conveying head 2, Fig. 1 (not shown), which intermittently rotates in steps of 30 degrees to carry part folded bags to a series of operating stations placed circumferentially outside the head at the positions where it is stationary. Bag forming.-A web of filter paper, cut from a reel 72, Fig. 10, is contacted by the front of a mandrel 28 and bent into U-shape around the mandrel sides. The leading end of the mandrel has a groove into which the paper is pressed, Fig. 13 (not shown), to form an end pleat. Transverse benders 126, 127 form the first lateral folds of the bag with consequential forming of flaps 130a by bending wrapper portions 129, 130 above and below the mandrel on to the top and bottom of a stationary member 129a. The bag then passes through a funnel 125 having elements 125a-125c, Fig. 13, to press the folds into V-shaped grooves in the edges of the mandrel. They also fold down the protruding portions to form the bag shown in Fig. 15. The bag is discharged from the mandrel on to a movable support member (34), Fig. 6 (not shown), where it is grasped by the grippers 30 of one of the twelve arms, after which the support retracts and the arm moves successively to stations S2, S3 where pressers (44), (45), Fig. 7 (not shown), act to consolidate the folds. Cutting.-A web of filter paper 99 fed to a bag-forming mandrel 28 in a machine for making and filling tea-bags (see Division B8), is drawn from a reel 72 by a driven roller 82, and braking roller 83. The rollers 82, 83 and a rotating knife 84 are mounted on a vertically reciprocating head 73, and, during part of the upwards movement of the head when the absolute velocity of the web is zero, i.e. downward motion of the web is cancelled by upwards motion of the knife, the knife severs the end portion of the web. Roller 100 mounted on a leaf spring 101 keeps the web tensioned and the relative speeds of the roller 82 and the knife 84 may be varied by interchangeable gears which connect them. To prevent the web from becoming slack, a braking system (113), Fig. 5 (not shown), is mounted on a hub (112) which carries the reel 72. The braking effect caused by a spring-loaded member (113c) pressing against a disc (113d) mounted on the hub (112) is variable manually.

Abstract: 1480636 Straight chain primary alcohols and their esters CHEMISCHE WERKE HULS AG 18 Sept 1974 [19 Sept 1973 15 May 1974] 40615/74 Heading C2C An ester of a straight chain C 6 -C 20  primary alcohol with a C 4 -C 20  monocarboxlyic acid is prepared by reacting a C 6 -C 20  straight chain 1-chloroalkane and/or 1-bromoalkane with an alkali metal salt of the monocarboxylic acid, in the presence of at least 1 mole per cent of free monocarboxylic acid relative to the alkali metal salt of the monocarboxylic acid, at a temperature of at least 150‹ C. The free acid preferably but not essentially corresponds to that forming the product ester; and alcohol for example one corresponding to that forming the ester, may also be present. The ester may then be saponified, e.g. in an alkaline medium, and the free C 6 -C 20  primary alcohol isolated; for isolation of the alcohol, a residue from an oxoalcohol or from the Alfol process, the residue being of higher boiling point and easily separated by distillation from the required alcohol, may be added to the product of saponification, the required alcohol distilled off and the residual solution of the monocarboxylic acid used for further ester formation. A mixture containing predominantly 1- chloroalkanes for use as starting material may be obtained by chlorination of one or more straight chain C 6 -C 20  paraffins, partial dehydrochlorination removal by distillation of resultant olefins, unreacted paraffins and impurities, and fractionation of the sump product to obtain the 1-chloroalkanes. 1-Bromoalkanes may be obtained by hydrobromination of α- olefins under free radical conditions, by cleavage of ethers with hydrobromic acid or by degradation of carboxylic acids or their salts. Acids used are isobutyric, caprylic, 2-ethylhexanoic, a C 8 /C 10  mixture and behenic; comparison examples using acetic and propionic acids are also given; in general the sodium salt is used, with some free acid present.

Filed: 1965-09-24
Abstract: 1,155,423. Gas turbine engines. PLESSEY CO. Ltd. Sept.23, 1966 [Sept.24, 1965], No.40797/65. Heading FIG. In a gas turbine engine fuel system, fuel entering at an inlet 2 passes by way of a backing pump 10 and a gear pump 11 to a line 12 provided with a pressure relief valve 13 and thence via an acceleration control unit 14 for preventing compressor surge, a manual throttle valve 1, an auxiliary throttle valve 7 and a pressurizing valve 23 to an outlet duct 17 leading to the burners. A link valve 22 co-operates with the acceleration control unit 14. The excess of the fuel delivered by the pump 11 over the rate determined by the acceleration control unit 14 is returned via a bypass line 16 to the inlet of the pump 11. A bypass valve 4 connected between the inlet to the manual throttle valve 1 and the inlet 2 is controlled jointly by the aggregate pressure drop across the throttle valve 1 and the auxiliary throttle valve 7 and the air-intake total pressure, the latter acting in a bellows 18 opposed by a vacuum capsule 18a. The auxiliary throttle valve 7 is also acted on by the aggregate pressure drop across the throttle valves 1 and 7 by means of a piston or a diaphragm member 7b. The aggregate pressure drop is controlled jointly by the by-pass valve4 and the auxiliary throttle valve 7, the former exerting a coarse control and the latter exerting a fine or trimmer control, whereby the aggregate pressure drop is regulated in accordance with the air-intake total pressure. This provides an altitude compensation whereby the engine idling speed increases with altitude. Instead of being responsive to the aggregate pressure drop across both valves 1 and 7, the by-pass valve 4 (and preferably the auxiliary valve 7 also) may be responsive to the pressure drop across the manual valve 1 only.

Title: Improvements in and relating to an arrangement for suspending by cords or similar flexible carrying means, an x-ray tube or other medical unit
IPC: A61B6/00
Filed: 1958-12-18
Abstract: 888,569. Lifting loads. DANSK RONTGENTECHNIK A.S. Dec. 18, 1958 [Dec. 23, 1957], No. 40907/58. Classes 78 (2) and 78 (5). [Also in Group XX] An X-ray tube or other medical unit is suspended by cords whose length can be increased or decreased to lower or raise the tube, the arrangement being such that the upper ends of the free-hanging portions of the cords move away from or towards the central axis accordingly, the said free-hanging portions making an angle of substantially less than a right-angle with the horizontal. In the form shown, this latter movement is achieved by winding the suspending cords round four grooved drums 9, 10, 11 ... arranged in cruciform fashion, and rotated simultaneously from a central motordriven worm-gear. The X-ray tube 2 is carried by a support 1 which is suspended by cords from the drums. As shown, cords 5 and 6 are wound on drums 9, 10 respectively, cords 7 and 8 on drums 10, 11, and so on. Each drum has two different cords wound on it, and consequently has double grooves, of fairly large pitch. As the drums wind up the cords to raise the tube, the point of contact with the drum of each hanging portion of cord moves inwards towards the centre, and vice versa when the tube is lowered, so maintaining the stability of the apparatus. The same effect may be obtained by using simple (non-grooved) winding drums, and providing some auxiliary means for moving the drums themselves inwards or outwards. The entire apparatus can be movably mounted on rails 13 suspended from the ceiling, and may be given a second direction of movement by a further set of rails at rightangles. An indicator 16 attached to the support 1 shows the height of the tube. Specification 738,237 is referred to.
