Title: Improvements in and connected with apparatus for measuring and delivering liquid by volume
IPC: B67D7/16
Filed: 1928-02-07
Abstract: 311,215. Garvie, J., and Smith Patent Pump Co., Ltd., S. Feb. 7, 1928. Fixed-chamber apparatus.-Liquid is delivered alternately to the opposite sides of the partition 2 which reciprocates within the measuring cylinder 1. Supply to and delivery from the chamber is controlled by a plug valve 6, acting in conjunction with means wherebv reversal of the valve is possible only when the partition is at the end of its stroke. The partition 2 carries with it a rod 11 journaled in the ends of the cylinder 1 and protruding into the space adjoining the ends of tubes 12 leading to the opposite ends of a. cylinder 13. Within this cylinder a member 15 moves in correspondence with the partition 2 and is recessed between its ends. Into this recess falls a rod 17 which supports a hollow plate 21 and carries an abutment 25 projecting into the path of a segmental projection on the valve reversing lever 27. 'The tube 12 may be filled with oil or balls, or the tubular arrangement may be replaced by linkwork. Pawls 22, 22<a> on opposite sides of the plate 21 engage a ratchet wheel 24 which is thus advanced the space of one tooth for each stroke of the partition 2. An audible indication of the completion of each stroke is given by means of the gong 45 struck by a hammer having a spring-loaded arm 47 extending into the path of pins 46 on the wheel 24. An arm 44 extending from the frame 21 is linked by a connection 43 to the spindle of a counting-mechanism 41. A pointer 33, movable over a dial 34, is mounted on a hub 35 and rotated with the wheel 24 against a torsion spring which is allowed to assert itself and return the pointer to zero by pressing a knob 37 on a rod 38. The pipe 9 by which the liquid from the pump 10 ascends is continued as an inverted U of which the descending limb is united to the housing of the cock 6. An air vent is situated at the highest point of the pipe 9 and glass windows are placed at the bends in both the supply and discharge pipes.

Title: Improvements relating to automatic means for adjusting the body of a motor vehicle having independent road wheel suspensions
IPC: B60G17/027
Filed: 1957-02-04
Abstract: 815,175. Road vehicle suspensions. DAIMLER-BENZ A. G. Feb. 4, 1957 [Feb. 10, 1956], No. 3830/57. Class 108(2) Control means for effecting automatic vertical adjustment, in dependence on loading, of the body of a motor vehicle having independent road wheel suspensions, comprises a single valve for controlling power  means operative for effecting the said adjustment, and this valve is operatively connected between lever arms fixedly mounted on members of the respective independent wheel suspensions of an axle, or is mounted on one of the said members and connected by a linkage to the other. In the example shown in Fig. 1 the control valve 11 is articulately mounted on arms 9, 10 rigidly connected to rocking half axles 1, 2 which are pivoted at 3, 4 on an axle gear box housing 6 and acted on by coil springs 7, 8. The control valve 11 comprises a casing connected with the arm 9 and a piston connected with the arm 10. The valve is connected through a pipe 14 to a reservoir (Fig. 2, not shown) fed with oil under pressure by a motor driven pump. The valve 11 also has a return flow pipe 18 and a pipe 23 connected to an adjusting cylinder 24. The cylinder 24 and its piston 26 are connected to arms 25 and 27 respectively which are fixedly attached to the ends of torsion bar springs 28 and 29 which are additional to the main springing 7, 8. Movements of the half axles 1, 2 are communicated through the arms 9, 10 to the valve 11 and either cause oil to be fed through the pipes 14, 23 to the adjusting cylinder 24 to put the torsion springs 28, 29 into operation, or they cause the springs 28, 29 to be put out of operation by permitting oil to pass back through pipe 23, valve 11 and pipe 18 to the reservoir. A delay device prevents operation of the torsion springs 28, 29 unless movement of the axles 1, 2 continues for a certain period or exceeds a certain limit. In Fig. 3 the invention is applied to a front axle suspension comprising wishbone links 30, 31 and 32, 33 and coil springs (not shown). The control valve 38 is mounted between arms 34 and 35 rigid with the links 30 and 31 respectively. The valve 38 has a feed pipe 39, return pipe 40, and a pipe 41 connected to an adjusting cylinder 42 articulated between arms 36 and 37 rigid with the links 30 and 31 respectively. The arm 36 is connected through a spring 43 with the cylinder 42 while the arm 37 is connected to the piston 44 in the cylinder 42. Operation is similar to that in Fig. 1. Fig. 4 (not shown) illustrates a modification of Fig. 3 using air springs in place of coil springs and wherein the control valve is rigidly disposed on one of the lower wishbone links and actuated by an arm connected through a rod to an arm fixed on the opposite lower link.

Title: Improvements relating to electrical recording apparatus
Inventor: REDDING ROBERT JAMES
IPC: G01D9/30
Filed: 1959-02-04
Abstract: 887,474. Recording-apparatus. EVERSHED & VIGNOLES Ltd. Feb. 4, 1960 [Feb. 4, 1959], No. 3964/59. Class 106 (4). Recording-apparatus comprises a row of electrodes 1 perpendicular to the direction of travel of a record strip divided into groups each corresponding to a denominational order and each electrode corresponding sequentially to a digit in that order. The electrodes 1 take the form of discs, separated by insulating strips 2, to which voltage can be applied through conductors 4, the lower end 5 of each acting as a scraper to keep the disc clean. Corresponding to each group of electrodes 1 there is a common roller electrode 6 connected to a conductor 7 and the circuit is completed through the thin metallic film on a thin plastic backing which forms the record strip 3. Since the current density at the points of contact of the metallic film is much greater at a disc 1 than at a roller 6, the film will be vaporized at the disc 1 selected in each group according to the digital value of the variable being recorded. The time to the nearest minute can be recorded with twelve electrodes for the hours and two groups of five and nine for the minutes, controlled by clock mechanism energizing appropriate electrodes in sequence. As many as 24 variables in a process plant may be recorded side by side with one time record and if the variables are in analogue form one analogue-to-digital converter only need be used as the time for each encoding and recording need be only a fraction of a second, so that all measurements may be recorded at stated times virtually simultaneously.

Title: Production of a new antibiotic bromotetracycline by fermentation
IPC: G01N33/487
Filed: 1955-02-10
Abstract: A new broad spectrum antibiotic bromotetracycline is produced by culturing a bromotetracycline strain of Streptomyces aureofaciens, particularly Actinomyces RO 1441 (described), in an aqueous medium containing 3 to 10 per cent of a carbohydrate, 0.1 to 1.5 per cent ammonium sulphate, 0.2 to 0.9 per cent calcium carbonate, 0.02 to 0.5 per cent of an alkali metal or alkaline earth metal bromide and 1 to 3 per cent of a special malt extract (composition disclosed) as sole organic nitrogen source.  The pH is 6.5 initially; the temperature 22 DEG  to 35 DEG  C. and preferably 27-31 DEG  C.; the duration of cultivation is 36 to 160 hours and is preferably under submerged aerobic conditions.  Specified preferred carbon sources are glucose, dextrins and sucrose; specified minerals are sodium sulphate, magnesium sulphate, manganese sulphate and zinc sulphate.  The bromotetracycline is isolated by acidifying the broth with hydrochloric acid, filtering and extracting with butanol or amyl alcohol in the presence of sodium chloride as salting out agent. After removal of the solvent by evaporation and salt by filtration, the residue is dissolved in water and the pH adjusted to 5.0. Alternatively, calcium chloride is added to the filtered broth and the pH adjusted to pH 8.0 with sodium hydroxide.  The precipitated calcium bromotetracycline is filtered, treated with sulphuric acid and the hydrochloride produced by adding hydrochloric acid and sodium chloride to the solution of sulphate and thereafter extracting with butanol.  Alternatively, the broth is adjusted to pH 7.5 with calcium hydroxide, the resulting calcium bromotetracycline dissolved in hydrochloric acid and the solution so formed extracted with butanol or amyl alcohol.  The hydrochloride may be further purified by adsorption on synthetic magnesium silicate and elution with methanolic hydrogen chloride at pH 1.5.  Bromotetracycline has formula <FORM:0772149/IV(b)/1> and forms salts with mineral acids and alkali metal or alkaline earth metals; it is soluble in 1 to 7 carbon aliphatic alcohols, slightly soluble in water and insoluble in ether; <FORM:0772149/IV(b)/2> - 196 DEG  (C=0.5 in 0.1 N. HCl); shows adsorption maxima in the infra-red region of the spectrum at the following wavelengths expressed in microns: 2.88, 3.0, 6.06, 6.22, 6.32, 6.58, 6.88, 7.08, 7.52, 7.67, 7.86, 8.13, 8.3, 8.68, 8.9, 9.2, 9.55, 10.39, 10.61, 11.53, 11.87, 12.12, 12.54, 12.77, 13.23, 13.62 and 13.98.

Patent GB-588466-A (GB)
Title: An improved manufacture of solidified mineral oils
IPC: C10L7/02
Filed: 1945-02-19
Abstract: Comprises a stabilised gelled mineral oil wherein the gelling agent is formed by reacting in the oil a mixture of higher fatty acids and a fat rich in chemically-combined acids selected from the group consisting of the saturated fatty soap acids and/or a fatty oil rich in chemically-combined hydroxylated unsaturated acids, the proportions of fatty acids to fats and/or fatty oil in said mixture being from 3 : 1 to 3 : 2, with sufficient caustic soda for complete saponification of the mixture.  Higher saturated fatty acids, such as stearic, palmitic &c. are preferred, and may be partly replaced by rosin (abietic acid), the free fatty acids preponderating.  The neutral fat or fatty oil ingredient functions as the stabiliser and its nature and the amount used are highly critical.  The predominating fatty acids in the fat or fatty oil should be higher saturated fatty acids such as stearic, palmitic &c. or unsaturated hydroxyacids such as ricinoleic, respectively, only minor amounts of the simple unsaturated fatty acids such as oleic being present. In an example, stearic acid, 3.5 parts, wood resin W.C. grade, 1.75 parts, castor oil, 3 parts, and kerosine, 3 parts, are mixed at about 90 DEG F., about 85 parts by weight of gasoline and 4 parts of 20 to 25 per cent. aqueous caustic soda solution are added, and the mixture stirred at room temperature, and allowed to stand for about 48 hours. A firm solid gel is formed which is easily softened by agitation, but gradually reverts on standing to the firm condition.  It is extremely stable against bleeding of the spirit or separation of the soap.  If the castor oil is omitted from the composition, the product forms quite well, but subsequently suffers almost complete separation.
