Title: Improvements relating to transfer gears for vehicles
Filed: 1962-01-30
Abstract: 938,523. Differential gearing. DAIMLERBENZ A.G. Jan. 30, 1962 [Feb. 4, 1961], No. 3493/62. Class 80 (2). In a limited-slip bevel differential for the transfer gearing of a vehicle four-wheel drive the sun pinions 16, 17 are of different sizes for transmitting unequal torques through the outputs 18, 19, and mechanism is incorporated for automatically increasing within limits the resistance to relative movement if the shafts 18, 19 rotate at different speeds. In the arrangement shown in Fig. 1, the mechanism includes a displacement pump of the type in which balls 25 are mounted in bores 24 in communication with sinusoidal displacement cells 22, increasing throttling of the liquid occurring as the slip increases. In the modification according to Fig. 2, friction discs 28, 29 are mounted between the pinions 16, 17 and the end walls of the differential casing, the discs being pressed into engagement by the tooth pressure between the pinions 16, 17 and the planets 15 when slip occurs. In a further arrangement, Fig. 3 (not shown), the pinions 16, 17 are formed with conical friction surfaces engaging complementary surfaces on rings secured to the differential casing.

Inventor: KERR JOHN
IPC: C10G27/08
Filed: 1961-02-01
Abstract: A method of lowering the mercapton content of a hydrocarbon or mineral oil containing mercaptans comprises contacting the oil in the presence of oxygen with a catalyst composition comprising a copper salt, a chloride, water and a calcined clay or clay-like material. Clay or clay-like material is defined as an oxide or silicate of Al, Mg, Ca or Fe or any mixture or compound thereof which when immersed in water or other liquids undergoes physical breakdown but which after heating at 250 DEG  C. or more for up to 10 hours becomes resistant to such physical breakdown in liquids. Examples given include sepiolite, attapalgite, fuller's earth, bentonite and bauxite.  Comparative examples of mercaptan removal from oils are given.
Patent GB-751378-A (GB)
Title: An improved charcoal filtering medium and method of producing the same
IPC: C01B31/08
Filed: 1954-02-09
Abstract: A charcoal filtering medium is prepared by pulverizing peat to a controlled particle size within limits appropriate for its use as a filter, removing soluble impurities and carbonizing the treated product.  Baled granulated peat is broken down into lumps which are pulverized in a hammer mill, the particles being swept by air to a separator having at least two stages.  In the first particles not passing a 50 B.S. mesh are trapped and the rest are passed to a final stage in which particles passing a 250 B.S. mesh are removed and the trapped residue is carbonized in an inert atmosphere at a temperature between about 400 DEG  and 600 DEG C.  The charcoal is also cooled in an inert atmosphere.  It may be mixed with other fine charcoal to alter the filtration rate.  Soluble impurities are removed before carbonization by acetone, alcohol, petroleum hydrocarbon, &c.  The particle size may be controlled by sieving to pass 50 B.S. mesh before carbonization and in addition to pass 60 B.S. mesh afterwards, particles passing 250 B.S. mesh then being removed or not as desired.

Abstract: 247,584. I. G. Farbenindustrie Akt.- Ges. Feb. 14, 1925, [Convention date]. Hydrogenation, destritctive.-The production of liquid hydrocarbons by treating carbonaceous solids at high temperatures and pressures of at least 50 atmospheres with hydrogen or reducing gases containing free or combined hydrogen is conducted in presence of chemicallv combined sulphur. One or more sulphides, especially of the iron group, mixed or not with metals, metalloids. oxides, hydroxides, carbonates, or other hydrogenation catalysts or inert materials, are particularly suitable. Sulphates and sulphites may be used. Suitable gases are hydrogen, water-gas. or mixtures of hydrogen with nitrogen, carbon dioxide, sulphuretted hydrogen, steam, or methane or other hydrocarbons. The hydrogen may be produced in the reaction vessel bv the action of steam on carbon monoxide or coal or hydrocarbons. In an example, a mixture oi lignite with 5-10 per cent of iron sulphide is treated at 500‹ C. and 200 atmospheres with a current of hydrogen. The issuing gases are cooled to condense the liquid hydrocarbons, replenished with hydrogen, and re-circulated, the coal ashes being removed to make the process continuous. The iron sulphide is preferably made bv treaty iron with sulphuretted hydrogen at 700‹ C. and 200 atmospheres pressure. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of mixtures of activated charcoal or coke with the sulphide, and the use of ammonia in place of hydrogen.

Abstract: 468,978. Counting-apparatus. INTERNATIONAL COIN COUNTING MACHINE CO., Ltd., and RAND, L. A. Feb. 11, 1936, No. 4150. [Class 106 (i)] In a coin-counting machine of the type which ascertains the value of batches of mixed coins a mechanism for indicating the total and subtotal of the coins passed through the machine comprises two coaxial shafts each actuating an indicator, the shafts being normally coupled for rotation as a whole by the coin counting mechanism and being capable of relative rotation independently to enable the sub-total indicator to be reset after each operation. In the machine shown in Figs. 1 and 2, the coins are carried round by a table and caused to operate a quadrant rack 1 to an extent depending on the value of the coin. The rack 1 meshes with a rack 2 rotatably mounted on a hollow shaft 3 and having an extension 4 carrying a pawl 5 engaging the teeth of a ratchet wheel 6 loose on the shaft 3. The wheel 6 carries a pointer 7 that co-operates with a scale 8 to indicate the total value of the coins. Inequalities in the diameter of coins of the same denomination are allowed for by a link 9 pivoted to the extension 4 having a roller 11 at its end engaging the teeth of an annular ring 13. Each rotation of the ratchet wheel 6 through a snail cam 14 thereon operates a bell-crank 15 to actuate a counting mechanism 16. On a shaft 19 coaxial with the hollow shaft 3 is mounted a sub-total pointer 18 having projecting lugs 22 adapted to engage between the teeth of a wheel 23 secured to the shaft 3 so that the pointer 18 rotates with the pointer 7. The shaft 19 carries a snail cam 25 that operates a bell-crank to actuate a second counting mechanism 26. By pulling out the knob 24 against the action of spring 30 the lugs are disengaged. so that the sub-total pointer 18 can be zeroized. Rotation of the knob 24 before pulling it out serves to zeroizing the total pointer 7.
