Patent GB-120798-A (GB)
Title: Improvements relating to Controllers for Electric Motors.
Inventor: ELLISON GEORGE
IPC: H02P1/02
Filed: 1918-05-31
Abstract: 120,798. Ellison, G., and Anderson, J. May 31, 1918. Controllers, checking-devices for.-The forward motion of a controller is stopped, when an excessive current passes, by a stop actuated by a solenoid core, and a small backward movement of the handle permits the return of the core without releasing the stop. The core g of the coil a is balanced by the pull of the spring h, and its end engages a lever k pivoted in a plate j mounted so that it can move laterally for a short distance. A spring control pawl l is pivoted to the plate and engages a peg n on the coil base o and engages also the bar i attached to the core g. When the motor current is excessive, the core g rises and lifts a projection on the lever k to engage a stop q on the disk p so stopping the forward movement of the controller. If the forward pressure on the controller handle is maintained, the plate is moved and the pawl l depresses the bar i and core g, but the lever k still engages the stop q. If the handle is moved back the lever k drops, and if the motor current is at a safe value the forward motion may be continued, but if the current is still excessive the plunger g will again be lifted to stop the forward movement. In a modification, the solenoid core operates a lever l which moves the two-armed lever k<1>, k<2> into the position shown, so that a roller engages one of the stops q. The slight forward movement which is permitted after this returns the solenoid core to its initial position.

Patent GB-891823-A (GB)
Title: A process for the purification of epoxides
Inventor: REAY WALTER HARKNESS
Filed: 1960-05-23
Abstract: A compound containing an epoxide is purified by treating the compound with an alkali metal or alkaline earth metal borohydride of the formula M(BH4)n, M(BH3X)n, M(BH2X2)n or M(BHX3)n where M represents the metal, n the valency and X represents an alkyl, aryl, alkoxy group or halogen atom.  The preferred epoxides are alkylene oxides, e.g. ethylene oxide or styrene oxide, particularly those containing less than eight carbon atoms per molecule, but other epoxy compounds such as epichlorohydrin, glycidic acid, glycide and other a ,b -epoxy carboxylic acids or alcohols may be purified.  More rapid removal of impurities is obtained if the borohydride is dissolved in water.  The epoxide may be pre-treated with a drying agent, e.g. calcium hydride or alumina, batchwise or continuously.  The purification may be effected batchwise by passing the epoxide into a tank where it is treated with borohydride and then distilling off the epoxide.  In a continuous process, the borohydride is injected into a column tray of a distillation column in which the epoxide is submitted to continuous distillation.  Alternatively, the borohydride may be injected into the top of a distillation column, a time tank or similar device being incorporated to increase the contact time.

Title: Improvements in tunnel kilns
IPC: F27B9/30
Filed: 1929-06-14
Abstract: 334,951. Woodall-Duckham (1920), Ltd., Doulton & Co., Ltd., and Bailey, C. June 14, 1929. Tunnel kilns.-In a tunnel kiln having superposed groups of flues built into the side walls of the heating and cooling zones, the desired temperature gradient within the kiln is obtained by increasing the total cross sectional area of the superposed flues from the outer and colder to the inner, and hotter ends of each zone. In the kiln shown the increase is obtained by varying the lengths of the flues, and to minimize overheating and undercooling of the goods at the top of the kiln, the longest heating-flue C is at the bottom and the longest cooling-flue J is at the top. The heating-flues are fired by burners I and each communicates with the next longer flue by end and intermediate openings G, E, E<1>. The flues of the cooling-zone are connected by openings K<1>, L<1>, and the air supplied to the uppermost flue through ports M is withdrawn for supply to the burners through the ports N. The depth of the flues may increase from the shortest to the longest, or the flues may all have the same crosssectional area and may be in groups of varying number, so that the heating effect will be uniform over the height of the kiln.

Title: Hoist drum in combination with a control system therefor
IPC: B66D5/26
Filed: 1974-04-29
Abstract: 1422100 Winches MANITOWOC CO Inc 29 April 1974 [25 July 1973] 18688/74 Heading B8B [Also in Division F2] The drums 10, 11 of hoist are driven from an engine 12 through a torque converter 35, the control system of Fig. 1 being operable to apply torque to one or both of the drums 10, 11 to drive it or them in a direction in which cable is taken up, the brake associated with the or each drum being released when the drum or drums commence rotation. The torque converter 35 comprises a driving impeller 37 connected to the engine 12, a torque output turbine 38 mechanically connected to the drums 10, 11 and a control sleeve 36 which, in the position shown in Fig. 1 prevents torque being transmitted to the turbine 38 but which is movable through a range of positions in which increasing amounts of torque are transmitted from the engine 12 to the drums 10, 11. So that the converter 35 can selectively power the drums clutches 51 are interposed between the converter and the drums, the clutches being under the control of respective actuators 52 which are controlled by respective valves 53 which in turn are opened by a respective manually positionable lever 43 or 44 so that movement of one of said levers to a first position causes engagement of the associated clutch with the associated drum and on futher movement of the same lever an associated throttle valve 45 is operated to cause the operation of an associated pneumatic actuator 42 against the action of a spring 41, the actuator 42 causing movement of the torque converter sleeve 36 which results in the rotation of the drum in a direction in which cable is taken up. A rotation sensor 46 associated with the drum detects its rotation and completes an electrical circuit to an associated normally-closed solenoid valve 47 which opens and thus permits air flow to a pneumatic actuator 30 to cause release of the brake 13 or 14 against the action of a spring 28. The forces exerted by the actuators 30, 42 are proportional to the amount of further movement of the lever 43 or 44. When it is desired to pay out cable from one of the drums 10, 11 a push button 59 on the associated one of the levers 43 or 44 is depressed thereby causing pressure fluid to be fed to an hydraulic motor 55 through a valve 56 which is opened by a pneumatic actuator 57 controlled by a solenoid operated valve 58, the depression of the push button also causing the release of the associated one of the brakes 13, 14 by energizing a solenoid 61 controlling a normally closed valve 62 so as to apply air pressure to the associated actuator 32. If the rate at which cable is paid out is too rapid the torque converter 35 may be brought into play by movement of the associated lever 43 or 44 to oppose the motor 55, and thus slow down, stop or even reverse the pay-out of cable.
