Title: Improvements in or relating to hydraulic crane fittings or attachments for self-propelled vehicles
IPC: B60P1/54
Filed: 1919-05-26
Abstract: 138,529. Flower, J. W. May 26, 1919. Vehicle fittings and attachments; cranes.-A motor-vehicle is fitted with an hydraulic crane operated by pumps driven by the engine of the vehicle. The vehicle a carries a standard b enclosing the rotatable crane cylinder d within which slides the ram h having the jib i mounted on its upper end. A suitablylocated pump (not shown) driven by the engine of the vehicle supplies pressure fluid to a valve chamber 11, Fig. 7, fitted with an upper valve t controlling the supply through a pipe 12 and swivelling connexion o to the crane cylinder. The lower valve u controls the outlet to the return pipe 2. A control handle z on a spindle y fitted with a cam x is used to operate the valves. With the cam inoperative, the pressure fluid closes the bottom valve, raises the top valve, and passes into the crane cylinder, raising the load. When the cam lifts the bottom valve, the pressure fluid from the pump passes into the return pipe, while a further movement of the cam raises both valves, there being a lost-motion connexion v between them, thus allowing the fluid in the cylinder and from the pump to pass into the return pipe and the crane to lower the load. Bv means of a handwheel 3 carrying a worm on its spindle engaging a worm-wheel on the crane cylinder, the crane can be slued. Specification 24547/08 is referred to.

Patent GB-299073-A (GB)
Title: Process for conditioning or treating water in boilers and the like to prevent incrustation and corrosion
IPC: C02F5/08
Filed: 1927-05-17
Abstract: 299,073. Gordon, J. May 17, 1927. Incrustation and corrosion, preventing.-Incrustation in boilers is prevented by adding a soluble carbonate to the water in the boiler in such proportions that calcium is precipitated as carbonate rather than sulphate or hydroxide, i.e., in the form of sludge rather than adherent scale. The same conditions also favour the precipitation of magnesium and iron salts, silicates, and other minor impurities in non-adherent form. Soda. ash, sodium bicarbonate or barium carbonate may be used, the last-mentioned reducing the sulphate concentration by precipitating barium sulphate. Hydroxyl ions are produced in the boiler water by hydrolysis of the sodium carbonate, and tend to prevent corrosion, but may cause precipitation of calcium hydroxide if in excess. The hydroxyl concentration may be limited by the use of a bicarbonate or by means of carbon dioxide. A series of curves are prepared, Fig. 5, showing the concentration of carbonate radical, corresponding to the concentration of sulphate radical at different boiler pressures, which it is necessary to maintain to prevent precipitation of calcium sulphate. Water may be removed from the boiler for separation of sludge, and then returned. Specification 299,074 is referred to.

Abstract: 514,521. Machines for working land; distributers for manures and seeds. SIMMONS, A. W. May 7, 1938, Nos. 13713 and 32815. [Class 6 (i)] A machine for making holes in the ground comprises vertically reciprocating tines which are retained in the same vertical plane during the piercing operation notwithstanding the forward movement of the machine. The tines are hollow and contain vertically reciprocating cleaning rods. Fig. 1 shows a machine in which tines 17 are carried by a platform 16 the ends of which engage slots in bars 13 attached to cranks 14, 15. The crank 15 is fixed to a shaft 6 which is rotated by a motor 8 which also drives the rear wheels 4 of the machine. The tines 17 are thus reciprocated vertically during the forward movement of the machine. To retain the tines in the same vertical plane during the piercing operation the ends of the platform 16 pass through vertical slots 21 in plates 22 which can move longitudinally on stationary guides 23. As the machine moves forward the plates are moved backwards relatively to the machine and thus maintained stationary relatively to the ground by means of cams 24 keyed to the shaft 5 of the cranks 14. The cams 24 abut against the plates 22 and springs 25 return the plates 22 to their initial position. The tines are telescopic and are urged downwardly by springs in their casings 27. Cleaning rods within the tines are controlled by levers 20 and the cams 24. The tines may be pointed and provided with a screw thread. Fig. 5 shows the machine fitted with means for depositing seeds or fertilizer in the holes formed by the tines 17. A hopper 32 is normally closed by a plate 30 from which a tube 31 leads to the ground. The plate 30 is carried by an arm 29 attached to the plate 22 which in its backward movement brings the tube 31 under the hopper 32.

Abstract: 909,505. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Sept. 2, 1960 [Sept. 4, 1959], No. 14085/62. Divided out of 900,347. Class 39 (4). In a nuclear reactor fuel element comprising a nuclear fuel member contained within a protective sheath, the fuel member is provided with a zone at which oxidation can occur in preference to oxidation of the remainder of the fuel member. In one example, the fuel member is a uranium bar provided with a coating, e.g. of nitride, which protects it against oxidation, this coating being omitted over a small area or areas where sheath leakages are more likely, for example adjacent welded end caps of the sheath. In another example, the uranium bar is provided with one or more blind holes filled with a substance which oxides in preference to uranium and preferably has a low neutron absorption and an increase in volume on oxidation ; a suitable substance is a uranium/carbon alloy containing at least 500 p.p.m. of carbon. By providing a zone of preferential oxidation, a fuel element with a faulty sheath will burst more rapidly and can be detected earlier either by the normal coolant monitoring or by a strain gauge as in Specification 900,347.
