Title: Improvements in or relating to cable, reel or drum cradles
Inventor: DALE LEONARD HURWORTH
IPC: B65H49/24
Filed: 1956-03-09
Abstract: 795,407. Cradles for cable drums. DALE ELECTRIC (YORKSHIRE), Ltd. Jan. 8,1957 [March 9, 1956], No. 7453/56. Class 99(2). A cradle for supporting cable reels or drums during reeling or unreeling of cables comprises spaced rollers 8, 10 carried by frame members 1 ... 4, and means for locking the roller 8 against rotation. As shown, the frame consists of U-section girders 1, 2 welded at their ends to cross-pieces 3, 4, the latter being shaped as a ramp. To allow adjustment of the roller 10 relatively to the roller 8, the axle 9 of the former engages slots 11 in the frame member 1 and recesses 13 in the frame member 2 ; the axle ends have opposed flats to prevent rotation, the rollers being provided with ball races at each end. The locking means comprises a bolt 14 extending through an L-shaped slot 15 in the side member 1 and held by a bracket 16. A spring 18 acting on the bracket and a collar 17 urges the bolt to the unlocked position when the bolt arm is in the horizontal leg of the slot 15. To lock the roller, the bolt 14 is pushed towards it, the bolt head 20 engaging an aperture 21 in the roller, and the bolt 14 is depressed through the vertical leg of slot 15 which locks it against releasing action of the spring. In use, the reel is rolled up the ramp 4 and on to rollers which have been adjusted to the desired spacing. Cable is reeled off, the drum rotating on the rollers, further rotation being halted by application of the locking device.

Abstract: 694,065. Heat insulation, drying air. MINIKAY, Inc. April 4, 1951 [April 5, 1950], No. 7786/51. Classes 34 (i) and 64 (ii) In a system for drying the insulation 12 between outer and inner surfaces of the walls, floor and ceiling of a cooling . chamber, conduits 40, 46, 56, a dehydrator 34 and spaces 18 in the walls &c. form a continuous circuit separate from the interior of the chamber and through which air is circulated. Further, the dehydrator contains an absorbing medium, such as silica gel, insoluble in water and which lowers the water vapour pressure of the air to a value lower than the saturated vapour pressure of water in air at the temperature of the cooling chamber and, furthermore, a heating chamber 60 is included for regenerating the absorbing medium after a predetermined quantity of moisture has been absorbed. Cork or multi-layer insulation 12 is supported by a structure 10 coated with asphalt 16 and is faced with plaster 14. The air spaces 18 may be formed by multi-layer insulation, or by parallel distance pieces as described in Specification 641,487. Air, sucked by a fan 54 through layers of silica gel 36 held between screens 38, is passed by the conduit 56 to a channel 20 along an angle ot the ceiling and a waU for distribution through two walls. the ceiling and floor and also to branch conduits 28 and two channels 31 for distribution through the two remaining walls. The air returns for drying through a conduit 26 and two conduits 30, which have valves 42 to adjust the air flow, to the conduit 40 and the space between the silica gel layers 36. The conduit 46 from the dehydrator 34 to the fan 54 has ducts 48, 50 to atmosphere. Insulation 66 covers the conduits and the air retains a temperature near that of the cooling chamber. The silica gel 36 is regenerated, e.g. every day, upon an impulse from a clock, a valve 52 opening the duct 50 and closing the conduit 46 and a valve 64 closing the conduit 40 and opening a by-pass 58 containing a heating coil 62 in the chamber 60. Air is sucked into the duct 50 and after being heated passes through the silica gel and out through duct 48.

Title: Improvements in or relating to trifluoromethylthiaxanthene and -xanthene derivatives
IPC: C07D311/82
Filed: 1961-03-03
Abstract: The invention comprises trifluoromethyl xanthenes and thiaxanthenes of the formula <FORM:0925538/IV(a)/1> and their salts, wherein Y = S or O, R1 = H or OH when R2 is hydrogen, R1 and R2 taken together form a single bond, R3 = H or CH3 and Z is a basic nitrogen containing radical of not more than 15 carbon atoms such as dialkylamino, pyrrolidino, piperidino and 4-alkyl-, hydroxyalkyl-, acetoxyalkyl-, carbamoyloxyalkyl-, dialkylcarbamoyloxyalkyl-, hydroxyethoxyethyl-, hydroxyethoxyethoxyethyl- and benzoyloxyalkyl-substituted piperazino groups.  The trifluoromethyl group is preferably in the 2-position of the xanthene or thiaxanthene ring.  The compounds are made by reacting a trifluoromethylxanthenone or thiaxanthenone with an aminoalkyl magnesium halide Z,CH2,CH(R3),CH2,Mg.Halogen, dehydrating the resulting 10-aminoalkyl-10- hydroxytrifluoromethylxanthene or thiaxanthene by treatment with acid such as hydrochloric or sulphuric acid, or with an acid anhydride such as acetic anhydride to give the corresponding aminoalkylidene compounds of the invention, and, if desired, reducing, e.g. by catalytic hydrogenation to give the aminoalkyl compounds. Benzyloxyalkylpiperazinyl compounds prepared by the above procedures may be treated with mineral acid to give a hydroxyalkylpiperazinyl derivative which may in turn be acylated to give the corresponding acetoxyalkyl and dialkylcarbamoyloxyalkyl compounds or may be chlorinated to give a chloroalkylpiperazinyl compound, e.g. a chloroethylpiperazinyl compound from which hydroxyethoxyethyl or hydroxyethoxyethoxyethyl compounds are made by treatment with an appropriate glycol.  The carbamoyloxalkyl-piperazino compounds are made by converting the hydroxyalkyl piperazino compounds to the phenyl carbonate salt and treating with ammonia.  The products are used pharmaceutically suitably in the form of their salts with organic and inorganic acids (many specified).  1-Benzyloxyethyl- 4-chloropropylpiperazine is made by converting benzyloxyethanol into its p-toluenesulphonate, reacting with N-ethoxycarbonyl-piperazine to give 1-benzyloxyethyl-4-ethoxycarbonyl-piperazine, hydrolysing and decarboxylating to N-benzyloxyethylpiperazine, reacting with 3-bromopropanol to give 1-benzyloxyethyl-4-(3-hydroxypropyl)-piperazine and chlorinating with thionyl chloride.

[Also in Group XXXIII] In arresting means for aeroplanes and other vehicles comprising arresting nets or cables or the like having one or both ends thereof connected to a brake wire 1 adapted during the arresting action to be unwound from a brake drum 3 controlled by hydraulic or pneumatic brake means 4, a valve 12 for supplying pressure fluid to the brake means from a source of pressure fluid such as the cylinder 5, is adapted to be opened by " dog " means, such as the studs 14 on the drum 3, engaging levers 13 operating the valve 12 on movement of the brake wire. With such an arrangement, the brake action does not start until the vehicle has overcome the inertia force of the net, wires and drum and retardation is carried out more gently. Pressure fluid supply from the reservoir 5 is governed in its passage to valve 12 by the pressure reducing valve 8 which may be adjusted to give braking forces appropriate to the type of vehicle to be arrested, i.e. aeroplanes, motor cars or the like. Pressure gauges 9 and 10 indicate the pressures upstream and downstream of the valve 8 respectively. The brake means shown comprises plate compressor brakes 4 and 4<SP>1</SP> at each end of the drum, the pressure fluid supply being passed to the lower brake 4<SP>1</SP> by way of a central channel 15 which is of a selected volume so as to act to produce a graduated brake application.
