Title: Improvements relating to operating mechanisms, primarily for electric switches
IPC: F16B1/00
Filed: 1927-02-05
Abstract: 287.677. British Thomson-Houston Co., Ltd., Hamlyn, W. P., and Hunter, M. C. I. Feb. 5, 1927. Automatic circuit-breakers.- Operating-mechanism for holding a member 11 against a bias 20 until released by a small tripping force 40 is described as applied to a circuit-breaker. Fig. 2 shows the mechanism after release has been effected. The force 40 has caused a stop 36 to move from under a roller 35 thereby moving pivot 31 so that the joint 29 of a toggle 27, 30 has been able to pass from the lower to the upper side of its links. This has permitted the rod 26 to move upwards and therefore the joint 17 of a lap-over toggle 15, 16 (i.e. a toggle in which the link 15 was initially in compression, while the link 16 was in tension) to move clockwise, so that the pivot 12 and member 11 has moved to the right under the bias 20. The links 15, 16 are hinged to pivoted members 13, 19 of unequal length. To reset the mechanism, the handle 25 is raised to the position shown in Fig. 3, thereby moving the hinge 18 to the right and reforming the links 15, 16 into a lap-over toggle and by moving the joint 17 downwards, the tripping mechanism is reset with the roller 35 on the stop 36. Return of the handle 25 to its initial position, draws the toggle 15, 16 and hence the member 11 to the left against the bias 20 and retains it in the strained position owing to the pivot 22 passing the dead centre with reference to pivots 18 and 24. A catch may engage the handle 25 so that the stop 36 is moved from under the roller 35 should the handle be moved while the mechanism is set against the bias. Specification 183,978 is referred to.

Filed: 1972-01-14
Abstract: 1371761 Reading and checking meters for registering road charges NATIONAL RESEARCH DEVELOPMENT CORP 14 Jan 1972 [29 Jan 1971] 3491/71 Headings G4D D6Y D1D11 and D4A2 Apparatus for checking and reading a road usage meter on a vehicle comprises means for reading the meter and meter identification, means for applying an input which will advance the meter, if faultless, by a known amount and means for rereading the meter and comparing the difference between the two readings with the applied input. The "known amount" may be varied and the apparatus may show an error in meter reading immediately or, all the information may be stored on tape and sent to a central processor for calculation of amount owed. As described, the meter is operated by inductive loops buried in the road. The meter is a four decade counter with position encoding. The apparatus is connected to the meter by a plug which has 24 connections; four from lead 5 which connect, one to each decade; ten from lead 3 which connect to each position on each decade, like numbers on each decade being connected and ten from lead 6 which are fixed connections on the decade output positions so that they represent a number characteristic of the meter. A potential from terminal 31 is supplied in succession by contact 30 of switch S1 to each of the identification leads (lead 4) and to each of the decades (lead 5) and the resulting output is either displayed on fourteen display devices, each of which can display any digit from 0-9 or is converted to binary and recorded on tape. In operation, the meter identification and initial reading are read as described above. The number by which the counter is to be advanced is set in store 36 and oscillator 16 is set in operation, supplying pulses through transmitter loop 10 to the meter. These pulses pass to the tape and also to counter 34 from which they are fed to coincidence detector 35 which stops the pulses on coincidence between the count and the number in store 36. The new meter reading is taken; S1 scanning only the ends of lead 5 and this reading is again recorded on tape. A fault detector 39 may be used to signal incorrect operation of the meter.

Title: Improvements in or relating to hydraulic relay speed governors
IPC: G05D13/00
Filed: 1943-03-03
Abstract: 580,404. Fluid-pressure servomotorcontrol systems. KALIN, A. March 3, 1943, No. 3518. Convention date, April 1, 1942. [Class 135] In a speed governor of the type in which a speed weighing mechanism actuates a pilot valve to admit hydraulic pressure fluid to, or vent it from, a space on one side of a servopiston, and the space on the other side of the piston is loaded continuously by the pressure fluid, a further valve is interposed between the pilot valve and the servo-piston so that fluid can be vented from the circuit irrespective of the position of the pilot valve. As shown, the fuel regulator of the engine is actuated by a differential piston G, the smaller face of which is continuously subject to the pressure in a motive fluid supply conduit E while the larger face is alternatively connected to the conduit E or to a sump Sunder the control of a balanced piston valve -H actuated by a main centrifugal governor L adjustably loaded by a spring M. Motive fluid is supplied by a gear pump A provided with a reversible valve system and a spring-loaded accumulator B with a vent D. A follow-up action is obtained by means of a plunger N actuated by the piston G acting on liquid in a conduit O provided with an adjustable bleed port R and a piston P connected by a spring Q with the land H<1> of the valve H. The conduit I connecting the control valve to the power piston passes through a supplementary control valve with a movable seat and a tube 10 telescoping into the piston G. The movable seat 20 is lifted against the action of a spring 32 when the piston approaches the end of its fuel increasing stroke by the engagement of the piston with an adjustable tappet 33. The secondary valve 26 is carried by a spindle 23 provided with a collar 55 acted on by a spring 52 and is actuated under certain conditions to take over control from the main governor. For brake mean effective pressure control, a secondary speed governor is provided comprising centrifugal weights 47 carried by a tubular member 40 mounted in ball bearings and rotated by gearing from the main governor. In the event of an abnormal decrease of speed, the weights 47 permit a plate loaded by a spring 50 to act on the collar 55 so actuating the valve 26 to limit the fuel supply. For emergency hand shut down, the valve 26 is depressed by a push-button 69 on a rod 62 adapted to engage the end of the spindle 23. In the event of lubricating oil failure, a spring 64 normally held out of operation by a metallic bellows subject to lubricating oil pressure depresses the spindle 62. This spindle may also be depressed by an arm 75 to provide a " load limit " control. Specifications 550,568 and 556,421 are referred to.

Patent GB-581483-A (GB)
Title: Improvements in or relating to the refining of natural or synthetic fatty oils
IPC: C11B3/00
Filed: 1943-03-05
Abstract: Natural or synthetic fatty oils having a tendency to emulsify with or to be hydrolysed by water are refined to give products which have a desired resistivity or power factor, the refining process comprising treating the oils first with an aqueous agent for neutralising free acids, then at least once with a water absorbent and finally at least once with an absorbent for the neutralised acids and other impurities.  Oils which may be treated include castor oil and glyceryl triricinoleate while the refined oils are suitable for use as dielectrics in electrostatic condensers.  The neutralising agent may be caustic soda solution while the absorbent may be clay, carbon, cellulosic material or an anhydrous salt, fuller's earth being particularly suitable.  The adsorbent may be activated carbon or activated clay, suitable activated clays being fuller's earth, "Filtrol" (Registered Trade Mark) or bentonite.  In examples, castor oil containing free fatty acid is neutralised with aqueous caustic soda and then treated at least twice with fuller's earth.  In the treatment with fuller's earth, the neutralised oil is agitated with the earth and then filtered or centrifuged or alternatively the neutralised oil is filtered through a layer of the earth.  Filtration may be facilitated by adding filter aids such as diatomaceous earth. Where the amount of free acid present in the castor oil is large, the neutralisation with caustic soda may be effected in stages, each addition of caustic soda being followed by a treatment with fuller's earth. p   The Specification as open to inspection under Sect. 91 refers to a process of refining water-immiscible materials of the type that have a tendency to emulsify with or to be hydrolysed by water used in the refining process, characterised by treating the material once or several times with absorbent and separating the absorbent from the mass after each treatment, each of the steps being conducted under conditions that preclude the substantial deterioration or contamination of the material.  Water - immiscible materials mentioned are oils, fats and waxes of vegetable, animal or synthetic origin, ketones and halogenated oils.  This subject-matter does not appear in the Specification as accepted.
