Title: Improvements relating to crane control gear
IPC: B66C13/56
Filed: 1932-05-23
Abstract: 382,900. Crane control gear. COWANS, SHELDON, & CO., Ltd., KINDER, W. C., and BROADBENT, H., St. Nicholas Works, Carlisle. May 23, 1932, No. 14540. [Class 78 (v).] Crane control gear as described in Specification 378,102 is interlocked with the motor controller so that the brake must be applied to the winding drum before the controller can be operated for lowering under power and before the clutch can be engaged for lowering under brake-control. A fluid-pressure valve controlling the brake-gear is operated by a pedal on the shaft 28, and a fluid-pressure valve 4 for controlling the clutch-gear is operated by a slide 17 which is raised by depressing the end 16 of the controller handle 6. Normally, the brake is held off by the fluidpressure gear, the clutch is engaged and the controller can be turned for hoisting, the movement being limited by stops 12 on a disc 10. A latch-lever 14 pivoted at 18 and engaged by a spring 19 prevents rotation of the disc 10, and also locks the clutch-control slide 17 by means of a shoulder 21. To permit of lowering under power, the brake-pedal is first depressed, whereby rod 25 is raised and engages the lower end of the latch-lever so as to free the disc 10. The controller can then be operated for lowering, the disc 10 being turned against the action of a torsion spring 32. For lowering under gravity, the brake-pedal must be depressed to disengage the latch from the shoulder 22 on the slide 17. With the controller in the " off " position, the end 31 of the handle is beneath the end 17<1> of the slide 17, and the clutch can be disengaged by depressing the handle end 16. A gravity catch 16<1> retains the parts in this position and lowering is controlled by the brake-pedal, or by a hand-lever having a one-way connection with the brakeoperating lever. To re-engage the clutch, the controller is moved towards the hoisting position until the slide 17 has been lowered gradually by the sloping surface 34. In moving the controller back to the " off " position, a cam 41 on the disc 10 ensures that the end 31 of the handle passes beneath the slide at 17<1>.

Indicators actuated by floats. - A liquid level indicator comprises a float 3 freely movable on a guide member 1 and a cord or the like 13 for causing the float or a part attached thereto to move laterally to lock it on the guide member and by its movement give an indication of the position of the float. The latter comprises two hollow cylinders secured by plates 4 and 5, the latter of which is of U-form and carries a projection 6 adapted to enter the holes 7 in a member 1. When the float moves to the right to cause the projection 6 to enter one of the holes 7, the yoke of a sliding member 10 is pressed against the member 1 comprising springs 11, 11, which tend to press the float to the left. By pulling the handle 15 the cord bears against rod 23, which extends between lugs 9, 9, on plates 5, and causes the projection 6 to enter one of the holes 7. The movement of handle 15 gives an indication of the liquid level. On returning the handle the cord is removed from rod 23 and the springs free the float. The operating handle may be a lever, rack and pinion or rotatable drum. Ratchet teeth may be formed on member 1, or locking may be effected by friction.

Abstract: A process for the production of a cyclopropane derivative having the grouping <FORM:0874776/IV (b)/1> in which X and Y are halogen atoms or aryl groups which may be substituted, e.g. by alkyl, aryl, halogen or ether groups (at least one of X and Y being halogen), or of one or more reaction products formed therefrom by spontaneous splitting off of a hydrogen halide accompanied by isomerisation, comprises reacting an unsaturated compound containing one or more >C=C< grouping with a salt derived from an acid of the formula hal.CXY.COOH, where hal is a halogen atom, under conditions in which the salt is decarboxylated and in a medium yielding no protons under the decarboxylating conditions.  The unsaturated compound may be acyclic, carbocylic or heterocyclic other than compounds containing only aromatic double bonds, e.g. benzene, and may be substituted, e.g. by alkyl, aryl, halogen or ether groups.  A list of suitable compounds is given.  The salt used is preferably a metal, e.g. sodium or a quaternary ammonium salt of an acid such as trichloroacetic or phenyldichloroacetic acid and reaction may be effected by heating, e.g. at reflux, in a solvent such as dimethoxyethane or tetrahydrofuran.  In examples sodium trichloroacetate is reacted with cyclohexane to give 7,7-dichlorobicyclo-[4,1,0]-heptane, with 1,3,5-cycloheptatriene to give 8,8-dichloro-bicyclo-[5,1,0]-octa-2,4-diene, with butadiene to give 1,1-dichloro-2-vinylcyclopropane and with allyl chloride to give 1,1-dichloro-2-chloromethylcyclopropane. Chlorobenzene may be obtained by spontaneous dehydrochlorination and isomerisation of 6,6-dichloro-bicyclo-[3,1,0]-hex-2-ene obtained from cyclopentadiene and sodium trichloracetate.
