Title: Improvements in and relating to control apparatus for electric mine hoists and the like
Inventor: DOLAN HARRY
IPC: B66B1/12
Filed: 1954-07-27
Abstract: 767,149. Hoist control. ENGLISH ELECTRIC CO., Ltd. July 22, 1955 [July 27, 1954], No. 21952/54. Class 78 (5). Control apparatus for a mine hoist of the kind operable at will under two modes of manual or automatic control, includes a manuallyoperated control lever 10 which both controls the hoist under the first mode of control and effects the change-over to the second mode of control. As shown, the winch drum driven by a slip-ring induction motor is controlled by speed lever 10 and brake lever 60, the two levers being pivoted respectively at 12, 12B so that when said levers are moved to positions within their respective gates 11, 61 (Fig. 2), they engage the clutches shown to move bell-cranks 16 or 17, 65 or 66 to operate links 19, 19A or 100, 37, or 80, 101 or 67 in correct sequence to govern cam followers 90, 84 of cam wheels 86, 87, brake engine 70, change-over switches 38 and 98, master direction controller 18, speed reference controller 23 and speed regulator 24. Speed reference controller 23 and speed regulator 24 are operated from handle 10 through said links 37, 19A and change-over device 20. Said device has horizontal lever 20 which can be locked, by the sliding of bars 34, 35 when operated through crank lever 36 by link 37, so as to pivot either at 29 or at 30 when moved by link 19A so as respectively to influence either speed reference controller 23 through link 21, or speed regulator 24 through link 22, quadrant devide 25, link 48, linkage 26 and actuator 27. The system (Fig. 2) is shown under open-loop manual control. Speed lever 10 works in slots 151, 152 ; brake lever 60 works in slot 153. To change to closed-loop manual control brake lever 60 is kept in brakes-on position 158 whilst speed lever 10 is moved to slot 150 into position 156. (An interlock prevents this movement if lever 60 is not in position 158). Under this closed-loop control, lever 10 works in slot 151 and lever 60 works in slot 153. Similarly, the system may be changed to or from semi-automatic or automatic control. Thus, no separate lever is needed to move the system into or from any of these four methods of control and only two manual control levers are used.

Title: Causing colour changes in polymer plastics by irradiation
Inventor: PINNER SOLOMON HARRIS
IPC: B29C35/08
Filed: 1956-07-20
Abstract: Colour changes, penetrating the surfaces of polymer plastics are produced by exposing areas of such surfaces to high energy of which the monomer contains chlorine as a constituent element, radiation such as X-rays, alpha particles, gamma rays and high energy electrons.  The colour change so produced may be applied to indicating the amount of radiation received by materials which are to be exposed to selected doses of high energy radiation, by the inclusion, adjacent to the material and in the path of the radiation, of a piece of a polymer plastic which undergoes a visible colour change on exposure to substantially the selected dose.  Polymers such as polyvinyl chloride, polyvinylidene chloride and chlorinated rubber are particularly suitable for treatment and initially-coloured material may be used; sheets, films, coatings, plastic-impregnated paper, filaments and woven fibres may be treated.  The irradiation may be effected through a stencil, or a pattern may be produced by manipulating an electron beam; sheet material may be treated in the form of a stack or roll, giving multiple patterning.ALSO:Colour changes penetrating the surface are produced in vinyl and vinylidene chloride polymers and copolymers and in rubber hydrochloride by exposure to high energy radiation such as X-rays, alpha particles, gamma rays and high-energy electrons. The colour change so produced may be in a pattern and may be used to indicate radiation dose of the material or of other material or articles with which it is associated.

A switch which operates upon breakage of a frangible casing, by collision or crashing of aircraft or other vehicles, for example, comprises a glass envelope 1, a base seal 3 and a flange 2 with an insulating block 16 moulded therearound to carry terminals 15 connected to four or more rods 9. The ends of rods 9 are located in an insulating block 5 supported by a central pillar 4, contact eyelets 12 being provided as shown. An insulating block 18 slidable on pillar 4 and rods 9 carries bridging contact plates 28 and is urged by a spring 21 towards the contacts 12 but is held off by a stronger spring 23 as long as envelope 1 is unbroken. In an alternative embodiment (Figs. 2 and 4) the frangible envelope 29 restrains an insulating piston 36 against a spring 38 such that ribs 37 prevent spring blades 34 from bridging rods 31. Each rod 31 has an L-shaped spring blade 34 mounted on it (Fig. 4) such that not only is contact made if the piston 36 is released or forced towards the base seal 32 but also if the switch is subjected to a sideways wrenching force. The frangible envelope may be evacuated or contain a gas such as nitrogen, hydrogen or argon. In a modification (Fig. 5, not shown), the switch is rendered flame-proof by replacing the moulded insulating base block by a mild steel housing filled with a silicone elastomer, the frangible envelope and a standard end connector being attached by a threaded ring and bolts, respectively. Magnetic operation.-The switch of Fig. 2 is provided with a soft iron slug 40 in the head of the piston 36 which renders it possible to actuate the switch for test purposes, without breaking the envelope, by means of a suitable solenoid or permanent magnet.
