Title: Improvements in or relating to oil return device for motor cycle gears
IPC: F01M9/06
Filed: 1962-07-18
Abstract: 951,364. Lubricating. FICHTEL & SACHS A.G. July 18, 1962 [July 21, 1961], No. 27670/62. Heading F2A. In a lubrication system for motor-cycle gears, lubricant is conveyed by a gear-wheel 1 from a sump and into a wedge-shaped slot formed between said wheel 1 and a wall 3, which along with a recess in a gear-box 10 and a cover 6, forms said sump. At the narrow end of the wedge-shaped slot is a lubricant-collector 4 which is connected to the gear-space of a changespeed gear by a bore 5. In use, the gears are wet by the lubricant, the excess of which is collected by the collector 4 and returned, via the gear space of the change-speed gear and an aperture (not shown), to the sump.

Title: Separating trimethyl phosphate
Inventor: KOTTONG GERALD WAYNE
IPC: C07F9/11
Filed: 1962-07-19
Abstract: Trimethyl phosphate is purified by continuously feeding a charge including methanol, trimethyl phosphate and 10 to 35 mole per cent hydrogen chloride into a first zone maintained at -10 DEG  to 125 DEG F. while providing a residence time of 1 to 7 minutes, thereby separating from the reaction mixture a hydrogen chloride-methanol rich fraction, and then passing the residual mixture into a second zone maintain-tained at 180 DEG  to 290 DEG  F. and therein substantially removing the remaining hydrogen chloride. Higher purity trimethyl phosphate may the be obtained by the distillation of the residual mixture from the second zone by maintaining an overhead temperature of approximately 190 DEG  F. and a bottom temperature of 380 DEG  to 430 DEG  F.  In a preferred embodiment chloride impurities are further removed by passing the residual mixture from the second zone into an intermediate zone prior to the third (distillation) zone, said intermediate zone being maintained at substantially the same temperature as the second zone while providing a residence time of 10 to 50 minutes.  In another preferred embodiment a stripping agent is introduced into any one or more of the three zones, i.e. the first (separation), second (separation) or third (distillation) zone.  More preferably the stripping agent is introduced into the third zone and recycled to the first zone together with any hydrogen chloride remaining after the second zone or the intermediate zone.  The stripping agent is a liquid non-reactive with trimethyl phosphate and preferably has a boiling point between that of methanol and the phosphate and undergoes a phase separation with methanol and hydrogen chloride, e.g. acyclic, cyclic and aromatic hydrocarbons. Pressures of 0.1 to 0.6 p.s.i.a. and 0.1 to 3 p.s.i.a. are preferred in the first and second zones respectively and a residence time of 0.75 to 2 hours is preferably provided in the second zone.  In the examples, a vertical column packed with Raschig rings provides the first zone, reboiler associated therewith provides the second zone and a distillation column adjacent thereto provides the third zone. The intermediate zone, where used, comprises a tubular member from the reboiler to the distillation column.

IPC: F42C14/08
Filed: 1960-08-12
Abstract: 926,680. Firing devices for land mines. H. KLOSTERMANN, [trading as R. RINKER [Firm of]]. Aug. 12, 1960 [Nov. 24, 1959], No. 27979/60. Classes 9 (1) and 9 (2). A detonator for land mines has a casing 6, which may be of metal or a heat-resistant synthetic material and houses a striker 1 stressed by a spring 5. The striker is held away from a percussion cap 14 by a pin 2 passing through its head and an endless spring element 10, which has a waisted portion snapped into a groove in the striker and resting against a sealing cap 4 on the casing 6. Washers are placed above the striker spring 5 to prevent ingress of dirt and moisture. A nipple 8 extending into the casing carries the detonator charge and delay means and is closed by a cap 9. When a milled nut on the end of the safety pin 2 is removed, the pin can be withdrawn, the striker then being held in the cocked position by the stirrup 10. If a pull is applied to the stirrup on either side, the waisted portion ceases to support the striker, which is then driven by its spring against the cap 14. The striker may also be operated by direct pressure applied to its head.

Title: Preparation of radioactive oil with a radioactive halogen
IPC: G21G4/04
Filed: 1956-09-17
Abstract: In order to distribute a radioactive halogen isotope uniformly in an oil, an aqueous solution containing a compound of the isotope is mixed with an unsaturated oil or an oil containing unsaturated compounds and water is expelled from the mixture by heating to above the boiling point of water but below the boiling point of the oil. Suitable oils are cod-liver, lard, sperm, olive, castor and cottonseed oils, crude petroleum oil and its unsaturated fractions, and mineral lubricating and cutting oils; waxes liquefiable by heat may also be used.  Heating may take place at 120 DEG  C. for 4 hours. In Example (1), radioactive iodine, in the form of sodium iodide dissolved in a basic aqueous solution of sodium sulphite, is dispersed in crude petroleum oil; the composition is used for testing the residue of crude oil left in oil well cores after processing to remove the oil.  In Example (2), radioactive iodine is similarly dispersed in mineral lubricating oil and the composition is used for testing the amount of residual machine oil left on metal parts after a cleaning process.  Specification 795,028 is referred to.

Abstract: 500,383. Valve gear. KURETSCHKA, F. J. Oct. 22, 1937, No. 28855. [Class 122 (ii)] A rotating cam for poppet valve-gears has an auxiliary cam associated with it, which is mechanically controlled in a definite manner in both directions by means of a cut-off cam., The invention is described as applied to a gear of the type described in Specification 345,775. The exhaust cam D fixed or locked on the camshaft A is arranged by the side of an auxiliary cam D<1>. Both bear upon the same rollers operating the exhaust valves. The auxiliary cam D<1> delays the closing of the exhaust valve by the angle alpha. The main exhaust cam is provided with ramps R, R<1> which protrude into the slot G<1> of the auxiliary cam D<1>. The member B<1> connected with the cut-off cam carries a plunger P<1> which is spring-pressed to engage a hole H<1> at the end of the slot G<1> to lock the cam D<1> relative thereto. If the cut-off is decreased, and the member B<1> advanced in the direction of rotation, the cam D<1> is mechanically controlled in a definite manner through all cut-off positions with increasing compression until the cams D<1>, D are superposed. With all smaller cut-offs, compression is constant and the cams remain superposed. In the superposed position, the plunger P<1> rides up the ramp R<1> and unlocks the cam D<1>. A spring F presses on the cam D<1> and forces a tooth T therein into a groove V in the cam D and locks it. In a modification, Fig. 7, wherein the profiles of the cams are very short, to space a notch that may occur between the main and auxiliary exhaust cams D<2>, D4 and ensure a continuous profile, an intermediate cam D<3> is inserted. Further modifications are described in which a main exhaust cam and intermediate cam with auxiliary exhaust cam are employed.
