Title: Time delay unit
IPC: H03K17/292
Filed: 1965-06-15
Abstract: 1,106,496. Time-delay circuits. HANCOCK TELECONTROL CORPORATION. 15 June, 1965 [29 Sept., 1964], No. 25347/65. Heading H3T. A time-delay circuit is in the form of a bridge of which two arms comprise a series R.C. circuit across a D.C. source to establish the time constant, and the diagonal comprises a unijunction transistor with its emitter connected to the junction of the resistor and capacitor so that it fires when the capacitor voltage has reached a predetermined value. In Fig. 2 the voltage of base one of the unijunction is stabilised by resistor R4 and Zener diode D2, and resistor R5 in series with base two limits the initial current to less than that necessary to operate the relay L1. When the unijunction fires, the relay operates and closes contacts K1 to short the timing capacitor Ct. These contacts may be omitted if manual resetting by opening and closing switch 22 is used. Additional relay contacts (not shown) indicate that the time has been reached. Capacitor C1 stabilises base two potential against fluctuations in the supply voltage. For stabilisation against slow variations of supply voltage (Fig. 3, not shown) the unijunction bases are connected to potential dividers across the supply, and the voltage from base one fed to the relay via an amplifier. Resistor R4 can be omitted but contributes to temperature and current stability. The relay coil may be between base one and the bottom of R4 if only momentary closing is desired, or the potential across the bases can be increased so that leakage current holds the relay on. The delay time can be altered by varying Rt and/or Ct.

Title: Differential drive transmission
Inventor: WEBSTER HENRY GEORGE
IPC: F16H37/08
Filed: 1961-07-14
Abstract: 935,963. Differential gearing; ratchet clutches. STANDARD MOTOR CO. Ltd. July 13, 1962 [July 14, 1961], No. 25537/61. Class 80 (2). [Also in Group XXXI] In a transmission comprising two aligned output shafts driven through differential gearing from a reversible input shaft, one of the output shafts is connectable to the input shaft through one of two transmission devices, according to the direction of rotation of the input shaft, each device comprising two one-way driving devices of opposite hand driven at different ratios to limit the ratio of relative rotation of the two output shafts. A driving shaft 10 drives an input shaft 17 at one of two ratios through gears 23, 21 or 25, 22 and may also drive a power take-off shaft 16. The gear 21 meshes with a gear 28 rigid with the cage 29 of a bevel differential 30, 33, 34, driving two output shafts 35, 36 which may be either vehicle axle shafts or front and rear wheel drive-shafts. The output shaft 36 has rigid therewith two gears 50, 51 of different diameters meshing with gears 48, 49, respectively, having jamming roller freewheels A, B of the same hand, selectively clutchable through teeth 66, 67 to the shaft 17 by axial movement of a clutch sleeve 69 splined to the shaft 17. A third freewheel C of opposite hand is mounted between the gears 48, 49, the inner member of the freewheel being clutchable by sleeve 69-to shaft 17 on movement of the sleeve in either direction from neutral, and the outer member 56 being clutchable by a sleeve 60 to either of the gears 48, 49. The two sleeves 69, 60 are arranged to move both in the same direction simultaneously with a shaft to forward or reverse drive. In forward drive the sleeves 60, 69 are moved to the right such that the inner members of freewheels A and C are coupled to shaft 17 and that of B is free. Rotation of the output shaft 36 at the same speed as shaft 17 is permitted by gear 49 rotating slower and gear 48 faster than shaft 17 in which case the opposite handed freewheels A and C overrun. If shaft 36 runs faster than shaft 17 due to wheelspin the speed of gear 49 will correspondingly increase until, at a predetermined ratio between the shafts 36, 17, the freewheel C locks and prevents a higher relative rotation of the shaft 36. Should the shaft 36 rotate at the same relative speed but slower, due to slippage on shaft 35, the freewheel A will lock. In reverse, the sleeves 60, 69 are moved to the left and freewheels B and C perform similar functions of limiting the relative speeds of shafts 35, 36 with respect to shaft 17. In a modification, the shaft 17 supports two freewheels, of opposite hand, each bearing an unequal size gear pair meshing with complementary gears clutchable, by three ganged dog clutches, to the output shaft 36. To prevent locking of two freewheels on sudden torque reversal the dog clutch members between the sleeve 69 and the inner members of the freewheels are provided with circumferential clearance.

Title: Process for the production of largely saturated intermediate hydrocarbon distillates
Inventor: KAUFMANN HERMAN
IPC: C10G47/00
Filed: 1966-06-08
Abstract: In a process for the production of largely saturated middle distillate of low sulphur, nitrogen and oxygen content from hydrocarbon fractions of a higher boiling point by thermal treatment in the range 250-500 DEG  C., on fixed catalysts, in the presence of hydrogen or of gases containing the latter and at pressures of 30-150 atmospheres, the mixture of hydrocarbon and hydrogenation gas is converted hydrocatalytically in a first reaction zone, after which the still liquid products are separated from the reaction mixture under process conditions and returned to the first reaction zone, the evaporated hydrocarbon parts directly undergoing a further hydrocatalytic treatment with the hydrogenation gas in a second reaction zone and then being condensed and separated by distillation. The catalyst in both zones may be a Group VI and a Group VIII metal, e.g. tungsten and/or molybdenum with nickel and/or cobalt on active alumina with up to 30% silicic acid.  Examples show the production of up to 28% gasoline and 71% middle distillate from a vacuum distillate boiling in the range 260-500 DEG  C.

Abstract: 1,010,503. Fluid pressure servomotor systems. GENERAL MOTORS CORPORATION. June 19, 1964 [July 8, 1963], No. 25591/64. Heading G3P. [Also in Division B7] A control device for variable pitch propellers producing direct lift in a vertical take-off aircraft has two modes of operation. In one mode the propeller speed is maintained constant by a fine governor 210, 212 acting on a valve 180 which distributes oil from a pump 154 to a piston 214 on the pitch control shaft 12, and a safety governor 206, 208, with a tolerance of, for example, 3%. The safety governor is coupled to a valve 168, movement of which cuts off the oil supply to one or the other of pilot valves 172, 176, allowing it to close, and cut off the supply through passage 260 or 262 to a spring loaded piston 244 or 246 which is then urged to move the valve 180. A lock valve 196 is provided and is normally balanced against a spring by oil pressure at the end 194. In the event of hydraulic failure the valve moves to close the passages 260 or 262 to a spring loaded piston 244 or 246 which is then urged to move the valve 180. A lock valve 196 is provided and is normally balanced against a spring by oil pressure at the end 194. In the event of hydraulic failure the valve moves to close the passage 224, 226 locking the output 12 and nence the propeller pitch in the position at which the failure occurred. Control may then be effected manually through mechanical connections (Fig. 1, not shown). The governor settings are varied by movement of a sleeve 228 through a cam 232 operated by an input rod 238. In the other mode of operation, the beta mode the propeller pitch is varied by the pilot. A valve 184 is moved by a rod 264 to connect passages 164, 276, allowing oil pressure to depress a plunger 240 and render the governors inactive by raising the follower 230 on to the cam flat 242. The valve 180 is then controlled by movement of the rod 264 acting through a floating lever 266 and a rod 270, feedback being provided by a cammed surface 272 on the lever 266 and a follower 274 on the output shaft 12.

Title: Manufacture of naphthoquinone derivatives
Filed: 1923-10-18
Abstract: 4-Arylamino-1-arylimino-2-naphthoquinones (1 4-diarylimino-2-naphthols) are produced by reacting upon 1-arylimino-2-naphthoquinones with a primary aromatic amine. According as the latter is in excess or not, the products contain two aryl radicles which are the same or different.  In the former case the initial product reacts with a further molecule of the primary amine.  The oxyarylnaphthylamine, which occurs as a by-product, may be treated, either with an oxidizing agent or in contact with air and a catalyst, in presence of a primary amine to produce a further quantity of 4-arylamino-1-arylimino-2-naphthoquinone.  Alternatively, the original reaction may be carried out in presence of oxidizing agents.  When metallic oxides, such as lime, baryta or copper oxide, are employed as catalysts, the naphthoquinone derivative generally forms a compound therewith.  When boiled with anhydrous glacial acetic acid the 4-arylamino-1-arylimino-2-naphthoquinones thus obtained undergo an intramolecular change to the isomeric 4 - arylimino - 2 - arylamino-1-naphthoquinones.  In examples, 1-phenylimino-2-naphthoquinone is caused to react with an acetone solution of aniline or p-toluidine, forming respectively 4 - phenylamino - 1-phenylimino-2-naphthoquinone and 4-p-tolylamino-1-p-tolylimino-2-naphthoquinone.  Solutions in chloroform of 4-phenylamino-1-phenylimino-2-naphthoquinone and p-toluidine react to give 4-phenylamino-1-p-tolylimino-2-naphthoquinone.  Air is bubbled through a mixture of 2-oxy-1-phenylnaphthylamine, hydrated cupric oxide and aniline or o-anisidine yielding respectively the copper compounds of 4-phenylamino-1-phenylimino-2-naphthoquinone and 4-o-methoxyphenylamino-1-o-methoxyphenylimino - 2-naphthoquinone. The isomerization described above is exemplified by the treatment of 4-phenylamino-1-phenylimino-2-naphthoquinone under a reflux with anhydrous glacial acetic acid, 4-phenylimino - 2 - phenylamino-1-naphthoquinone being produced. 4-Arylimino-2-oxy-1-naphthoquinones (4-arylamino-1 : 2-naphthoquinones) are produced by the hydrolysis by aqueous acids of the 4-arylamino-1-arylimino-2-naphthoquinones described above. An example shows the treatment of 4-p-tolylamino-1-p-tolylimino-2-naphthoquinone with concentrated hydrochloric acid.  The product, poured into water and drained, is a flocculent red precipitate which is purified by solution in caustic soda and reprecipitation by alcohol.  Specification 206,150 is referred to.
