Implements with adjustable tool frames; lifting-devices, power.-A railway-track weeding- machine equipped with a plough for uprooting the weeds and restoring the permanent way to its 'cross-section, is provided with means for raising the plough over obstacles, comprising winding- apparatus operated by compressed air and fitted with automatic braking or locking mechanism. The axle e of the winding-drums g is connected to the head of a compressed-air cylinder c by endless chains running over pulleys d, d<1> and fastened to a cross-head f on the piston rod. On the axle e is a braking-device i comprising friction discs i<1>. i<2> connected alternately to the axle e and to a housing k, being normally pressed together by a plate l acted upon by a spring m. A shank l<1> on the plate l extends into an air-tight chamber k<1> in which works a piston n. A multiple-way cock is connected with the lifting cylinders c and the chamber k<1> and arranged to admit air under the piston n before admitting it to the cylinder c to raise the plough. The movement of the piston n pulls back the plate l against the action of the spring m and thus releases the winding-drums. When the lifting-piston is at the end of its stroke it operates a trip finger which adjusts the cock automatically for exhausting the air in the chamber k' so that the brake may again lock the drums against rotation. For lowering the plough under its own weight, the multiple-way cock is adjusted by hand so as to cause a gradual exhausting of the air in the cylinder c and an admission of air into the chamber k<1>.

Title: Acid addition salts of thiaxanthene derivatives
IPC: C07D335/20
Filed: 1959-03-31
Abstract: The invention comprises acid addition salts of trans 2 - methoxy - 9 - (31 - dimethylaminopropylidene)-thiaxanthene substantially free from cis isomers and characterized by the free base having a melting point of 76 DEG C.-77 DEG C.  The trans isomers are obtained by p fractional crystallisation of the mixed cis and trans acid addition salts such as the hydrochloride, hydrobromide, sulphate, tartrate, citrate, acetate and lactate from solvents, for example from water, alkanols or ethers.  After isolation of the desired trans isomer by fractional crystallisation, the remaining isomer may be treated with a hydrogen halide in chloroform and evaporated to dryness to split off hydrogen halide and effect rearrangement to give a mixture of cis and trans isomers which may then be subjected to a further fractional crystallisation to separate the trans isomer.  The mixture of cis and trans isomers used as a starting material is made either by treating 2-methoxy-thiaxanthydrol with acrylonitrile, reducing the resulting 9 - b  - cyanoethyl - 2 - methoxy - thiaxanthydrol, e.g. with LiAlH4 or NaBH4, to 2-methoxy-9-g -aminopropyl-thiaxanthydrol and dehydrating and methylating either in one step by means of formaldehyde and formic acid or via the intermediate 2 - methoxy - 9 - g  - aminopropylidene - thiaxanthene; or by treating 2-methoxy-thiaxanthone with allyl magnesium bromide, hydrolysing to 2 - methoxy - 9 - allyl - thiaxanthydrol, treating with hydrogen halide to give 2-methoxy-9-g -halopropylidene thiaxanthene and reacting with dimethylamine.  Reference has been directed by the Comptroller to Specification 829,763.

Abstract: 757,820. Hydraulic apparatus; relief valves. BOSCH GES., R. April 14, 1954 [April 17. 1953], No. 10940/54. Classes 69 (2) and 135, A relief valve for a hydraulic lifting system is constructed so that the force tending to open the valve is unaffected by local fluctuations due to discharge of liquid through the valve. A valve comprises a housing 14 having apertures 15, 16 connected to the pressure line of the system, and apertures 17, 18 connected to the return line. In the event of excess pressure in the pressure line a piston 36 is moved against the action of a spring 32, thus moving a valve closure member 31 to bring an annular groove 40 into alignment with ports 42, liquid then discharging through bores 41 and the hollow interior of the member 31 into the return line. If the pressure continues to rise, the groove 40 moves into alignment with large ports 43, 44 so that the total amount of liquid supplied by the pump can finally flow off by this path.
