Title: Improvements in or relating to vehicles having hydraulic transmissions
IPC: B60K17/10
Filed: 1962-09-12
Abstract: 1,000,086. Hydraulic transmissions. C. VAN DER LELY N.V. Sept. 12, 1962 [Oct. 6, 1961], No. 34859/62. Heading F2C. [Also in Divisions A1 and B7] In a tractor having a variable ratio hydraulic transmission comprising a swash-plate pump 1 supplying a similar motor 2 and driven by an internal-combustion engine, a pump 12 driven by the engine supplies an hydraulically powered steering mechanism and an hydraulic lifting device and also supplies fluid to the transmission to make up leakage losses and to prevent excessive temperatures therein, the arrangement being such that the supply of fluid from the pump 12 to the transmission is not interrupted when the steering mechanism is actuated. The pump 12 is supplied from a reservoir 10 through ducts 11, 16 and comprises three intermeshing pinions 13, 14, 15 and two outlets, one supplying the control valve of the steering mechanism through ducts 17, 26 and the other supplying the control valve of the lifting device through a conduit 50. When the steering control valve is in a neutral position fluid flows around heads 31, 32 thereon and passes via ducts 40, 41, 42 to a duct 21 whence it is supplied through one-way valves 24, 25 to whichever of interchangeable feed and return duets 3, 4 between the motor 2 and the pump 1 is acting as the return duct according to the direction of travel. Excess fluid supplied to the feed duct passes through a valve 5 opened by the pressure in the feed duct and a duct 3 incorporating a spring-loaded valve 9 to the reservoir 10. When the steering control valve is operated fluid from the duct 26 is supplied to one side of a stationary piston 46 to displace a cylinder 45 connected through a rack and pinion 48, 49 to the steerable wheels of the tractor, and fluid displaced from the other side of the piston flows via one of ducts 40, 41 to the duct 21, whereby the supply to the transmission remains uninterrupted. In the inoperative position of the control valve 52 of the lifting device, fluid supplied thereto by the duct 50 passes via a duct 70 to the duct 21. To raise the lifting device the valve is moved to a position wherein a spring-loaded ball 57 engages a groove 54 and fluid is supplied through a non-return valve 77 to a cylinder 72. To lower the lifting device the valve is moved to a position wherein the ball 57 engages a groove 56 and a conical piston 67 lifts a spring-loaded ball 78 to establish communication between the cylinder 72 and a return duct 82 to the reservoir 10. If either the steering mechanism of the lifting mechanism is blocked or encounters undue resistance, fluid from the pump 12 is supplied directly to the duct 21 through either of oneway valves 19, 20 and excessive pressures within the system are relieved by a one-way valve 84. Two separate pumps may replace the pump 12 and the reservoir 10 may be provided with a cooler.

Title: Improvements in or relating to the treatment of fresh fruit, vegetable and similar juices
IPC: A23L2/84
Filed: 1934-12-05
Abstract: Fresh fruit, vegetable, and similar plant juices are preserved by treating with a weak solution of sodium chloride to prevent resinification and oxidation and then, without addition of acid, with a plant juice capable of enzymatically decomposing the proteid and pectose bodies, such as papaw juice or pineapple or other plant juices of the bromeliacae family, the decomposition products which precipitate being then removed, e.g. by filtration. Heating and cooling are avoided.  The juice may be clarified by centrifuging, ground filter paper being added to assist, before filtration which may be effected in a clarifying filter followed by a sterilizing filter to remove bacteria.  Air is excluded during these operations. In examples, after addition of a one per cent solution of sodium chloride and allowing to stand for 2 hours tomato juice is treated with papaw juice, pineapple juice with bromelin and juice pressed from yellow carrots with pineapple juice, the mixture being in each case left at 8 DEG  C. for about 25 hours, after which it is centrifuged and filtered; with orange juice a 0,4 per cent solution of sodium chloride is used, and papaw juice is added and the mixture left for 24-96 hours before centrifuging.

Title: Improvements in or relating to formaldehyde
Inventor: KRUEGER BRUNO OTTO
IPC: C07C45/78
Filed: 1959-10-15
Abstract: A stable composition of formaldehyde in aqueous urea or melamine is made by contracting formaldehyde in gaseous form countercurrently with a column of heated solution of urea or melamine dissolved in a liquid medium consisting of a mixture of water and a water-soluble alcohol having a boiling-point lower than that of water so that the formaldehyde gas rises through the liquid in intimate contact therewith, maintaining the proportion of the alcohol higher than that of the water in the upper part of the column and below that of the water in the lower part of the column, heating the column of liquid to a temperature at the bottom between that of the boiling point of the liquid at that point and the alcohol and at the top approximately to the temperature of refluxing of the alcohol, continuing the passage of the formaldehyde through the column until a concentrated formaldehydeacceptor solution collects in the lower part of the column and is withdrawn, heating the withdrawn material to distil off any remaining volatilisable formaldehyde and alcohol, withdrawing the alcohol from the upper part of the column, and supplying to the column additional amounts of the acceptor and alcohol, the additional acceptor being introduced into the column at a point above that of introduction of the formaldehyde gas. The formaldehyde may be used in the form of furnace gas from the conversion of methanol to formaldehyde.  The preferred alcohol is methanol but other suitable alcohols are ethanol, isopropanol, n-propanol and 3-butanol.  When the formaldehyde is supplied as gases from methanol converters the gases contain a small amount of acid which may be neutralised by the addition of a water-soluble metal hydroxide or carbonate or by an amine such as triethanolamine.  The urea or melamine may be used in amounts of 30-60% based on the formaldehyde and the final stable solution will be of the order of 1 mol of urea, for example, to 4 of formaldehyde.
