Title: Improvements in or relating to valve gear with rotating cams, driven by gears, for elastic fluid driving machines
IPC: F16K31/53
Filed: 1946-08-26
Abstract: 654,240. Engine valve gear. ALESSIO, G. Aug. 26, 1946. No. 25423. Convention date, June 1, 1940. [Class 122(ii) ] In a valve control apparatus for elastic fluid engines of the independent timing type disclosed i n S p e incations 170,855 and 170,877, both in Class 122 (ii) ], in which the opening and closing of the admission and exhaust valves is effected by rotating opening and closing cams, i.e. by the so - called " distinct function " cams, the admission opening and closing cams are secured on two independent shafts driven from a driving shaft through a chain of gears which are relatively movable without disengagement so as to effect angular displacement of one or both of the cams relatively to the driving shaft, and the exhaust cams are controlled by the said two independent shafts. As shown in Fig. 1, the gear train comprises interengaging axially displaceable helical gears 3a, 3c, mounted on the two shafts la, 1c, and a helical spur gear 4 located on the driving shaft 2 engaging with one of the axially displaceable gears, a control device being operated from a shaft 7 for axially displacing the gears 3a, 3c, on their respective shafts, 1a, 1c, in order to effect an angular displacement of the cams Ca<SP>1</SP>, Ca", and Cc<SP>1</SP>, Cc<SP>11</SP>. In the embodiment shown in Fig. 9 the independent shafts 1<SP>1</SP>a, 1<SP>1</SP>c are coaxially located with relation to the driving shaft 41 and the gear train is formed by a gear 38 rigidly connected to the driving shaft 41 adapted simultaneously to transmit motion to two similar gears 32a, 32c, respectively rigidly connected to the independent shafts 1<SP>1</SP>a, 1<SP>1</SP>c through two separate groups of satellite pinions 33a, 33c, the mounting of said pinions being such as to permit their rotation about a common axis. The pinions are mounted on beams 34a, 34c, connected to an operating shaft 37. Angular displacement of these beams by means of shaft 37 displaces the pinions 33a, 33c, which in their turn, by operating on the gears 32a and 32c change the angular position of the shafts 1<SP>1</SP>a and 1<SP>1</SP>c and thence the position of the cams Ca, Cc, with respect to the shaft 41. In a further embodiment the spur gear type of transmission gears of Fig. 9 is replaced by gearing of the bevel gear type.

Title: A Method of Producing Gases Rich in Methane
IPC: C01B3/50
Filed: 1967-06-01
Abstract: 1,183,925. Making combustible gas. METALLGESELLSCHAFT A.G. 1 June, 1967 [3 June, 1966], No. 25451/67. Heading C5E. In a method of making methane-rich gases by catalytically cracking hydrocarbons having a maximum B.P. of 350‹ C. with steam in the presence of hydrogen, the reactants are preheated to not more than 350‹ C. and then passed over a hydrogenating cracking catalyst, e.g. Ni or Co on an alumina or magnesium-aluminium silicate carrier. The catalyst may include 0-01 to 0-1% Pt or Pd, and the hydrogen may be obtained by recycling some product gas, or by delivering coke oven gas or refinery gas to the reaction. Preheating of the reactants is mainly by heat exchange with the product gas, and in one embodiment, see figure (not shown) petrol is heated to 160‹ C., mixed with hydrogen and heated to 330‹ to 350‹ C. and then mixed with super-heated steam at 27 atmospheres pressure. The method enables higher boiling hydrocarbons having an average of 10 to 25 C atoms per molecule, e.g. diesel and fuel oils, to be gasified without the formation of soot.

Title: Improvements in and relating to stop motions for spinning and like textile machines
IPC: D01H13/18
Filed: 1933-09-14
Abstract: 425,612. Stop-motions for spinning- machines for long fibre material. MACKIE & SONS, Ltd., J., and MACKIE, J. P., Albert Foundry, Belfast. Sept. 14, 1933, No. 25504. [Classes 120 (ii) and 120 (iii)] In stop-motions of the kind not employing a power-driven actuator and operated by a weight or spring to which a detector is connected for spinning machines for flax, hemp, jute, and like long fibre material, and particularly high speed jute-spinning machines, the detector and weight are connected by latching-surfaces so disposed that the weight tends to keep them in engagement while the yarn is intact and to assist their disengagement upon breakage. A detector 8, pivoted at 11 and normally supported by the intact yarn, is latched as shown in Fig. 3, to a link 9, which is connected to a lever 7 weighted at 15, or spring-controlled, so that, upon breakage, the detector swings clockwise and frees the link 9, whereupon the lever turns about its pivot 10 and a cam surface 16 thereon engages the pressing-roller 1 and separates it from the feed roller, at the same time nipping the roving thereagainst and preventing the drawing forward of the material by the rollers 2, 2. The effective length of the link 9 may be adjusted by a pin and slot connection 23 to vary the effect of the weight-lever 7 in accordance with the strength of the yarn being spun. The means for separating the roller may be distinct from that which grips the roving. The lever 7 tends to press the detector against the yarn, and the detector and link are maintained in engagement with each other while the yarn is intact by reason of the angular inclination alpha of the normal to the line of action X ... X of the link to the latching-face, this disposition also permitting a certain movement under variation of tension. Disengagement is assisted by the weight when the latching-face passes the normal to X ... X. The levers 7 are held out of action as desired during doffing by the engagement of the notched end 20 with hooks 19 on a shaft 18 which may be connected with the starting and stopping mechanism through, for example, a lost motion coupling such as described in Specification 367,852 or a centrifugal coupling so that the stop-motion may be locked until the yarns are fully tensioned. The levers 15 may be individually freed by turning the notched ends 20 about pivots 22. The weight 15 falling towards the front of the machine serves as a signal of the breakage of a yarn, and may be arranged to operate a light or a bell.

Abstract: 1157142 Separation of isotopic label amino acid racemates into their optical a. M H ZENK and J H SCHMITT 9 June 1966 [11 June 1965] 25659/66 Heading C2C Isotopic labelled DL α- or #-amino acid rac mates are separated into their optical D- and L- antipodes by selectively acylating the D part of the racemate by acetyl-CoA, propionyl-CoA or other active acyl CoA compound in the presence of acetyl-CoA: D-amino acid-o-N-acetyl transferase from yeast. The latter enzyme from yeast catalyses the transfer of the acyl group of the active acyl-CoA on to the amino group of D-amino acids and separation of the resulting N-acyl-D- amino acid from the unreacted L-amino acid can be effected by ion exchange absorption, chromatography, electro-phoresis or extraction with organic solvents. The separated N-acyl-D-amino acid component can be converted again to a DL- amino acid racemate by chemical methods and this process repeated until almost quantitative transfer of the original racemate into the more valuable L form is attained. The pure D form may be obtained by an analogous procedure involving racemization of the L form. In an example the extraction of the enzyme from freshly airdried brewers' yeast and its subsequent purification and assay are described and details are given for the separation of DL-alanine-1-<SP>14</SP>C into the pure D- and L-antipodes using acetyl-CoA in the presence of the enzyme. Several other amino acids to which the separation process may be applied are also specified and the method is applicable to very small samples of radioactive isotopic labelled amino acids.

Abstract: 1,111,527. Improving commutation in dynamo-electric machines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 June, 1965 [20 June, 1964], No. 25674/65. Heading H2A. In a commutating arrangement for small motors, e.g. for battery-operated record players, a discoidal printed commutator co-operates with brushes comprising at least two separate spring arms 10, 11 whose contact ends 16a, 16b are staggered with respect to the commutator. They are also skewed, either by angling the brushes, as shown, or by using curved slots 4 between the segments. Commutation is improved by the use of idle sectors 8 or gaps on the commutator and by the use of resistors 14 and capacitors 15 between the brush arms. The brushes may be of phosphor-bronze, and the commutator segments of copper, palladium, palladium-silver alloy, silver-copper alloy, or gold-plated nickel. The brush arms may lie one above the other.

Title: Improvements in or relating to processes of substituting hydroxyl groups for the acid radicals in liquid esters of inorganic acids or for halogens in liquid derivatives of hydrocarbons
IPC: C07C27/10
Filed: 1925-10-14
Abstract: The hydrolysis of esters of inorganic acids or of halogen derivatives of hydrocarbons is effected by heating with an aqueous solution of an alkali in the presence of the same ester of a water-insoluble fatty acid or its sulphonic derivatives.  Thus, according to the example, amyl chloride is heated with caustic soda solution and amyl oleate; the latter is probably continuously decomposed by the alkali to form amyl alcohol and sodium oleate, and regenerated by interaction of the sodium oleate with amyl chloride.  The amyl alcohol product is separated from the amyl oleate by distillation with steam, in vacuo or under pressure; the only by-product is a mixture of dihydroxypentanes. The process is stated to be applicable to the treatment of halogen derivatives of fatty and aromatic hydrocarbons and of mercaptans and organic sulphides; bromobenzene and the chlorides, mercaptans and nitrates of pentane, butane and propane are specifically mentioned.  The reaction is effected at a moderate temperature without agitation and without the use of high pressure, thereby avoiding the formation of olefines; it may be carried out continuously or intermittently with periodic removal of the hydrolyzed compound.  Amyl chloride is obtained by chlorinating pentane or a petroleum fraction of boiling-point 20-40 DEG  C.  Amyl oleate is prepared be heating amyl chloride with oleic acid and caustic soda.

Abstract: 644,607. Exciting dynamo-electric machines. PESTARINI, J. M. Sept. 22, 1947, No. 25685. Convention date, Sept. 20, 1946. [Class 35] The primary variator winding or windings of a metadyne motor having short-circuited secondary brushes, is excited with a constant component of excitation and a component produced by an auxiliary dynamo with a saturated magnetic field and excited by a constant component and a component derived from the voltage across the primary brushes of the motor. The primary brushes a, c are connected directly or through compensating windings to terminals A, C, connected to the supply 3, 4 whilst the terminals B, D, of the secondary brushes b, d, are short-circuited. A variator winding 5 is separately supplied and controls the extent of the motoring or regenerative action of the machine. In order to produce a characteristic having a sharp bend into regenerative operation at any particular speed a variator winding 13 is, fed from a saturated auxiliary dynamo 12 driven separately or from the metadyne. The field coils 16, 17, of the dynamo are fed from the supply mains and a separate constant source respectively. The desired characteristic may be produced by means of a variator winding 11 fed by a shunt wound regulator dynamo 10 driven by the metadyne and whose critical excitation build-up speed is equal to the fixed speed desired. Alternatively the same effect may be produced by a speed-responsive mechanical regulator. A further variator winding 7 connected across the primary brushes as shown, or a separately excited winding, may be used on the secondary axis, and if desired both such windings may be used. If it is desired that the motor shall take a falling current for a rising voltage, a second variator winding connected across the supply is put on the primary axis. Both the .primary and secondary currents may be taken through stator windings acting in their respective axes. Instead of using a plurality of variator windings fed by different sources as shown. these sources may be used to excite field windings on an amplifying metadyne which in turn excites a single winding on the main machine. Diagrams are given showing how the coils .may be disposed on the stator poles, a further amplifying metadyne being used in which several coils are carried on one pole, if desired. In modified forms, the brushes are not disposed in quadrature and the secondary brushes may be suhdivided into two short-circuited pairs. Specfication 449,924 is referred to.
