Title: Improvements in or relating to lubricating oils
IPC: C10M131/02
Filed: 1944-07-01
Abstract: Extreme pressure lubricating properties are imparted to a petroleum lubricating oil, or to an aromatic extract obtained by extracting petroleum with a selective solvent for aromatic hydrocarbons, by chlorinating it with sulphuryl chloride and then removing the labile or corrosive chlorine present. Sulphurization may precede or follow the chlorination with sulphuryl chloride, while during the chlorination a chlorination catalyst such as benzoyl peroxide may be present.  Labile or corrosive chlorine may be removed (a) by blowing in steam, then neutralizing, for example, with alkaline earth oxides or hydroxides, alumina, or similar powdered or granulated neutralizing agents, and finally filtering or (b) by washing with water, then neutralizing with aqueous solutions of such neutralizing agents as the alkali metal hydroxides or carbonates, calcium hydroxide, ammonia or other basic bodies, and finally, if necessary, filtering.  The chlorinated oil or petroleum extract thus produced may be used alone or may be added to unchlorinated lubricating oil or to a sulphurized petroleum extract, and it may be rendered soluble in or emulsifiable with water by adding any of the well-known solubilising or emulsifying agents used to produce soluble oils such as sulphonated fish oils or rosin soaps.  In examples, a mineral lubricating oil, a transformer oil or a solvent extract obtained by treating a lubricating fraction of petroleum with liquid sulphur dioxide, is chlorinated with sulphuryl chloride with or without benzoyl peroxide being present. The chlorinated oil is then steamed, (a) neutralized with slaked lime and filtered or (b) diluted with petroleum ether, water washed, filtered and then distilled to remove petroleum ether. The final product is used as such or blended with mineral lubricating oil.

Title: Novel antibiotic designated marcomycin and process of making same
Filed: 1957-04-17
Abstract: <PICT:0829327/IV (b)/1> A new antibiotic, marcomycin, is obtained by cultivating under aerobic and especially submerged aerobic conditions, a marcomycinproducing strain of Streptomyces hygroscopicus in a culture medium containing mould assimilable sources of carbohydrate, nitrogen and inorganic salts.  Specified sources of (a) carbohydrate, are glucose, starch, sucrose, dextrin and molasses, (b) nitrogen, are corn steep, soybean meal or flour, distillers' solubles, casein, amino acid mixtures, peptones, nitrates and ammonium salts, (c) inorganic salts are those yielding ions of sodium, potassium, calcium, phosphate, chloride and sulphate.  Trace elements and buffers may also be present. Cultivation is at pH 6.0-7.5 and preferably 26-30 DEG C., and the duration 2 to 5 days (submerged) or 5 to 10 days (surface). Preferred strains are Streptomyces hydroscopicus NRRL 2387, NRRL 2388 and NRRL 2389. Marcomycin is recovered from the broth by (a) extraction, and (b) adsorption.  Extraction is by means of an organic solvent such as propanol or butanol, preferably after saturating the broth with a soluble inorganic salt such as ammonium sulphate.  The crude obtained after removal of the solvent is purified by precipitation from solvents, by chromatography or by countercurrent extraction. Adsorption is on carbon or an ion-exchange resin of an acidic nature, e.g. "Amberlite" IRC-50 (Registered Trade Mark).  Acidic antibiotics such as hygromycin may be removed by adsorption on a basic ion-exchange resin.  An aqueous organic solvent, preferably alkaline, may be used to elute marcomycin from carbon.  Elution from an acidic ion-exchange resin is by means of aqueous ammonia or aqueous acid, e.g. HCl.  Marcomycin is effective against both gram - ve and +ve microorganisms; it has a molecular weight of 436, pK1a  of 7.20 and 8.95 in aqueous dimethylformamide solution; melts at 160-180 DEG  C. with decomposition; insoluble in ether, chloroform, ethylene chloride, hexane and benzene; soluble in water and ethanol, methanol, dimethylformamide and glacial acetic acid; stable in aqueous solution at pH1 to 10; contains 46.40% carbon, 7.48% hydrogen, 6.82% nitrogen and 39.30% oxygen; no absorption in ultra-violet in aqueous solution; in infra-red shows bands at 3.03, 6.01, 6.12, 6.24, 6.34, 8.10, 8.72, 9.30, 9.63 and 11.25 microns.  It is basic and forms salts with acids such as hydrochloric, sulphuric, phosphoric and maleic.  Salts or complexes are formed with (a) p-(p1-hydroxyphenylazo)-benzene sulphonic acid, (b) methyl orange, (c) phosphotungstic acid, (d) ammonium tetrathiocyanodiammono - chromate (Reinecke salt).  It is irritating to the skin.  It may be used as an anthelmintic in the treatment of animals (see Group VI).ALSO:Marcomycin, an antibiotic produced by the fermentation of Streptomyces hygroscopicus (see Group IV (b)), is incorporated in an animal feed for its anthelmintic effect.

Title: Improvements in control systems especially for aircraft
IPC: G05D1/08
Filed: 1942-09-07
Abstract: 594,120. Fluid-pressure servomotorcontrol systems. SPERRY GYROSCOPE CO., Inc. Sept. 7, 1942, No. 12615. Convention date, Sept. 5, 1941. [Class 135] A control system, particularly for automatic pilots on aircraft, including a relay valve actuated by a member subject to a controlling pressure has additional means for actuating the relay valve by a delayed pressure derived from the controlling pressure. Fig. 1 shows the invention applied to a system for controlling a rudder 89 by a directional gyroscope 1. The rudder is operated by a double-acting power piston 87 controlled by a relay valve 45 comprising a piston valve with three lands 69, 71 and 73 adapted to control the connection of the pipes 81, 83 leading to the power cylinder with a pressure supply pipe 63 and exhaust pipe 65. The outer faces of the lands 69, 73 are subject to the pressures in the pipes 81, 83 and the valve spindle 75 is coupled to three diaphragms 91, 93, 99. The chambers of the diaphragms 91, 93 are connected by pipes 43, 41 to chambers 35, 33 connected by ports 29, 30, 31, 32 in an adjustable seat member 27 with a chamber 25. A control valve housed in the chamber 25 comprising opposed and staggered semi-cylindrical blocks 21, 23, Fig. 2, is connected by its spindle 17 with the vertical outer gimbal ring of the gyroscope 1. This ring carries a compass card 13 visible through a window 15. The lower part of the chamber is connected through a passage 49 with the gyroscope casing which is exhausted through a conduit 51. The upper part of the chamber, 25 is connected to atmosphere by a pipe 47. Normally, equal pressures are maintained in the pipes 41, 43, but when relative movement between the control valve and its seating takes place a differential pressure is produced in the pipes 41, 43 causing a movement of the relay valve and resultant rudder movement. The chambers on each side of the diaphragm 99 are connected to the pipes 41, 43 through pipes 101, 103 filled with adjustable throttles 105, 107, the pipes being joined by a pipe fitted with an adjustable throttle 111. The pressure differentials on the pipes 41, 43 are thus slowly permitted to act on the diaphragm 99 which is smaller than the diaphragm 91, 93 in a direction to oppose the differential acting on the dia. phragms 91, 93. Specifications 531,388 and 531,391 are referred to.

Abstract: 459,017. Anodic coating of magnesium and its alloys. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. May 4, 1936, No. 12622. Convention date, June 1, 1335. [Class 41] Protective layers are produced on magnesium or its alloys by anodic treatment in an electrolyte containing at least one component from each of the following groups: (1) the water soluble hydroxides, (2) the water soluble carbonates, borates, polyborates and silicates, (3) the water soluble cyanides, cyanates and thiocyanates. The compounds employed may be those of the alkali and alkaline earth metals or of ammonium; a combination of ammonium compounds of all three groups is not however satisfactory. The electrolyte may contain in addition, preferably in lower concentration than the above a component from the group comprising the water soluble sulphates, nitrates, phosphates, halogenides, halogenates, chromates, tungstates and fluosilicates. An example of a suitable bath is sodium hydroxide 5 per cent, sodium carbonate 5 per cent, potassium cyanide 2 per cent and sodium tungstate 0À1 per cent. A temperature of 20-25 C. is suitable. A voltage of 16 later raised to 60 or 110 may be used or the voltage may be gradually raised from 1 to 60 or 110. Treatment may last one hour. The coated goods may be further coated with varnish, fat, oil, wax, colloidal hydroxides or silica gel, or may be dyed. Colouring treatment may be applied to the freshly coated articles or after storing according to the depth of colour desired.

Title: Improvements in or relating to semi-conductor diodes
Inventor: BEALE JULIAN ROBERT ANTHONY
IPC: C30B13/04
Filed: 1956-04-25
Abstract: 839,842. Semi-conductor diodes. MULLARD RADIO VALVE CO. Ltd. April 25, 1956, No. 12698/56. Addition to 820,611. Class 37. A semi-conductor diode of material with a carrier lifetime of less than 5 microseconds and comprising a PN junction is produced by introducing impurity for reducing the lifetime during the alloying process used to convert one region of the semi-conductor to opposite conductivity type to form the PN junction, and then diffusing the lifetime reducing impurity into the other zone of the semi-conductor. As shown in Fig. 1, a bent Ni wire 4 is placed in a Fig. 1 on an N-type Ge single crystal 2 and heated to about 850 C. for 10 minutes (i.e. above the eutectic temperature of Ni and Ge) to form a blob 6 of alloy. Heating is continued at 790 C. for 20 minutes to diffuse the Ni into the Ge sufficient to reduce the carrier lifetime but not to convert the region to P-type conductivity. The Ni-Ge alloy region then recrystallizes to form a P-type region. The Ni wire may be coated with an acceptor such as In or Ga to assist the conversion to P-type. Specification 789,931 is referred to.

Abstract: 371,611. Printing - surfaces. BARENNES, R. P., 6, Place St. Christoly, Bordeaux, France. April 30, 1931, No. 12778. Convention date, May 5, 1930. [Classes 100 (ii) and 100 (iii).] In the preparation of type-bars of varying length for printing tabular matter, each typebar is cast with a lug at a point separating the text from the blank portion of the bar, by means of a special matrix, the lugs serving as stops in a sawing-machine, whereby a number of bars can be cut to correct length at one operation. The matrix, Fig. 1, has a cavity 1, which produces on the type-bar, Fig. 3, a lug 2 of greater height than the printing-face of the bar. In the sawing-machine, which may have two saws 6, Figs. 10 and 11, and two movable tables, slotted rules 7, 8, one of which is pivoted, are provided on either side of the saw. The slots permit the passage of the type-bars, but arrest the lugs 2, which are clipped between the two rules, so that the lugs are held in alignment, as shown in Fig. 6. A group of bars can then be cut to the required lengths.

Title: Timing apparatus
IPC: G11B20/16
Filed: 1974-03-22
Abstract: 1456585 Transferring data WESTERN ELECTRIC CO Inc 22 March 1974 [23 March 1973] 12850/74 Heading G4C Transfer of data signals read from a recording medium 10 (Fig. 1) is controlled by delaying for a fixed period timing signals derived from the medium 10, delaying the read data signals, determining the timing relationship between one of the delayed data signals and an associated timing signal to control the total amount by which the digital signals are delayed. As described the read data signals are clocked (at a multiple of the data bit read-out rate) into a shift register 30 having a number of fixed stages FD1-FD2 (to provide a minimum compensation of one half a bit period) and a number of gated stages VD1-VD8 (to provide compensation up to the total anticipated data shift). Circuit 15 delays the timing information read by clock heads 4 for two bit periods before feeding it to signal generator 20 which provides a clock signal BT1-BTK for each bit of a data word. A check bit transition recorded during bit period BT2 is used for positioning the data bits of a word. A counter 50 is enabled to count pulses from oscillator 40 (also stepping the register 30) at the leading edge of the bit period BT2, its count being terminated when the check bit transition reaches stage VD4 of the register 30. The counter outputs then enable one of eight gates 601-608 to select the shift register stage from which the word is read to data pulse generator 80 which comprises two monostable multivibrators, AND gates 82, 84 at their inputs being strobed by a clock signal from the generator 20. The storage medium may be a drum or disc with the data stored in NRZ form. Modifications.-An existing data bit transition in the data words may be employed to adjust the read-out timing. All the fixed stages of register 30 may be eliminated.
Patent GB-357600-A (GB)
Title: Improvements in control gear for variable delivery pumps
IPC: F04B49/00
Filed: 1930-04-26
Abstract: 357,600. Reciprocating- pumps. BROWN BROS. & CO., Ltd. and WALLACE, W., Rosebank Iron Works, Edinburgh. April 26, 1930, No. 12891. [Class 102 (i).] In a pump having stroke-varying mechanism operated by the discharge pressure and a byepass valve, the latter is opened by further rise of pressure after the stroke has been reduced to minimum. A non-return valve 3 is interposed between the pump and the discharge pipe 1, and a piston 6, exposed to discharge pressure through a pipe 7, is operated against the action of a spring 17 to actuate a stroke-varying bell-crank lever 4, 5 through a spring connection 10. A rod 14, carried by the cross-head 25, has a collar 13, which engages a wing 12 on a cam-plate on a byepass valve 8 to open the valve. The valve is closed by engagement of the collar 13 with a wing 18, assisted by the action of a spring or fluid-pressed plunger engaging a wing 15. In a modification, Fig. 6, the crosshead 25 has a last-motion connection with the rod 24 of a plunger 23 having a lift-valve 27. At the end of the stroke of the plunger the valve 27 is opened and effects communication between byepass passages 9, 9<1>. In a further modification a plunger 30, Fig. 7, exposed to discharge pressure, operates a lever 33 through a rod 41 and link 43. The lever 33 carries a spring-pressed detent 34, engaging a detent 37 on a lever 35 connected by a link 50 to a byepass valve 32.

Filed: 1932-05-04
Abstract: 390,657. Locking control - levers. LAWES, G. W., Collingwood, Grosvenor Avenue, Carshalton, Surrey. May 4, 1932, Nos. 12895 and 13808. [Class 79 (iii).] In control - levers for change-speed gears &c. having locking means to prevent unauthorized use, positive irreversible means are provided for maintaining the lever inoperative if the lock is tampered with. A sliding sleeve 40 is connected by a Bowden cable 11 with a plunger 13 having a pin 26 in contact with cam face 25 on a ring 23 operable by a knob 22. When the knob is turned the plunger is raised and with it the sleeve 40. The lower end 57 of the sleeve is thus withdrawn from engagement with the gear 58. When the plunger rises lateral spring-pressed plungers 19, 20, 21 are pushed into recesses in a fixed sleeve 14 to lock the main plunger in raised position. Release is affected by rotating, according to the combination, rings 28, 29, 30, the eccentric inner surface of which bear upon balls which force the plungers 19, 20, 21 back into the main plunger. To prevent the sleeve 40 rising except when the lever is in neutral position it is formed with projecting arms 53 which pass into slots 50 in vertical plates 48 mounted on a partition 47. The slots have vertical portions 51 corresponding to the neutral position so that vertical movement of the arms 53 into them is permissible. Tampering with the mechanism would result in the normal travel being exceeded, in which case a plunger 54 carried by a spring 55 will drop into a hole 56 or 56a. If into the hole 56, connection with the selector device 58 will be prevented ; if into the hole 56a, a wider portion will descend into an aperture which normally houses the part 57 and will prevent the lower end of the lever from moving into gear-engaging position. In a modification, Fig. 7, normal locking of the lever is effected by causing a sliding block 60 to move between stops 61, 62, or 63, 64. If the movement is excessive, due to tampering, a spring-pressed plunger 65 moves into a recess 66 or 67 and cannot be withdrawn except by dismantling the mechanism.
