Title: Improvements in and relating to hydraulically controlled brake or clutch mechanism
IPC: F16D65/28
Filed: 1965-04-05
Abstract: 1,131,032. Hydraulic brakes; electromagnetically-released drum brakes; controlling clutches. BUTTERLEY CO. Ltd. and P. G. WESTMORELAND. 17 March, 1966 [5 April, 1965], No. 14453/65. Headings F2E, F2F and F2L. In an hydraulically-controlled brake or clutch mechanism incorporating a rotary member in the form of a brake drum 11, the speed of which is to be controlled, an hydraulic actuator 13 effects the engagement of the brake and a control pump being driven in a predetermined speed relationship to the brake drum 11 delivers hydraulic fluid to the hydraulic actuator 13 at a pressure determined by the speed of the brake drum 11 so that the latter achieves a desired speed. The pump 15 draws its supply of hydraulic fluid through a pipe line 15<SP>1</SP> from a tank 17 and delivers by way of pipe lines 18, 19 and 20 through a solenoid-operated valve 21 to the hydraulic actuator 13, the delivery of the pump 15 being proportional to the rotational speed of the brake drum 11 through the medium of a driving connection 16. At a predetermined rotational speed or " creep " of the brake drum 11, a predetermined volume of the output of the pump 15 is leaked to the tank through pressure-compensated flow control valves 22, 23. In the position shown the solenoid-operated valve 21 provided between the lines 19 and 20 such that the pump 15 is connected to the hydraulic actuator 13 and in the further position when the solenoid is energized both the pump and the hydraulic actuator are connected back to the tank 17. A relief valve 25 may be incorporated in the hydraulic system to prevent an excessive pressure build-up. A further solenoid-operated valve 24 controls operation of one of the valves 22. In order to provide a " fail-safe " feature the brake may be further actuated by spring means (not shown) and released by energization of an electro-magnetic actuator 14.

Abstract: 1,034,532. Protective arrangements. GENERAL ELECTRIC CO. April 8, 1964 [April 30, 1963], No. 14461/64. Headings H2H and H2K. In an arrangement for protecting an alternating current apparatus, e.g. the heating element 315 of an electric bedcover, from overtemperature conditions, a relay 313 has two coils 320, 322 with a temperature sensing element 312 connected in parallel with the coil 320 and a rectifier 314 connected across the other coil 322 to avoid noise or hum. The sensing element 312 comprises conductors 317, 319 separated by a layer 318 of a material which has a high impedance at normal temperatures and a low impedance at high temperatures. The layer 318 is in parallel with the relay coil 320 and the relay is normally sufficiently energized to maintain its contacts 323, in series with the heating element 315, closed. On overheating, current flowing through the layer 318 causes an increased voltage drop across a resistor 311 resulting in reduced energization of the coil 320, so that the relay drops out. The relay 313 may be initially closed by momentarily operating a start switch 376, a switch 362 in the heating element circuit being opened whilst the switch 376 is closed. To switch off the element 315, an " off " switch 377 is operated to short-circuit the relay coil 320. The temperature of the bedcover is normally controlled by a bimetallic control switch 340.

Title: Process for the separation of sulphur from oxime-sulphur mixtures
Filed: 1954-05-19
Abstract: An oxime is recovered from a mixture of sulphur and an oxime, e.g. the product of the reduction of a primary or secondary nitro compound with hydrogen sulphide, by treating the mixture with liquid sulphur dioxide, preferably at - 20 DEG  C., whereby the oxime only is dissolved, filtering off the sulphur, and evaporating off the sulphur dioxide.  An example describes the recovery of capraldoxime from the reaction product of the treatment of 1-nitrohexane with hydrogen sulphide.  In a modification a cycloaliphatic oxime is converted into the corresponding lactam, which is also soluble in sulphur dioxide, during the separation, i.e. a cycloaliphatic oxime-sulphur mixture is introduced together with a lactamizing reagent, e.g. sulphuric acid, oleum or sulphur trioxide, into liquid sulphur dioxide, preferably at - 14 DEG  to - 17 DEG  C.  An example describes the conversion of cyclohexanone oxime into caprolactam.ALSO:Sulphur is recovered from a mixture of sulphur and an oxime, e.g. the product of the reduction of a primary or secondary nitro compound with hydrogen sulphide, by treating the mixture with liquid sulphur dioxide, preferably at -20 DEG C., whereby the oxine only is dissolved.
