Title: Improvements in or relating to fluid blast electric circuit interrupters
IPC: H01H33/98
Filed: 1944-04-25
Abstract: 578,422. Oil-break circuit-breakers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 25, 1944, No. 7724. Convention date, May 28, 1943.. [Class 38 (v)] A circuit-breaker has arc-extinguishing units 8, each of which contains a pressure-generating contact 16, intermediate contact 20, and movable contact 11. The contact 16 is pivoted at 17 in a pressure-chamber 15, and biased open by a spring 30. The contact 20 is biased downwards by spring 22 and contact 11 is fixed to crosspiece 9. An insulated rod 23, biased downwards by a spring 25, is slotted at 26 to pivotally receive a pin 27 on contact 16. The other end of rod 23 has a lost-motion connection 40, 41 with cross-piece 9. A piston 34, with apertures 35, slides between fixed discs 32, 33 on rod 23 in chamber 36, the bottom of which is normally closed by spring-urged disc 38. The contacts 11, 20 are surrounded by shaped insulating plates having vertical vents 44 and horizontal inlet vents 45. The breaker is opened by moving member 9 downwards, thus opening contacts 11, 20 and simultaneously, by movement of rod 23, the contacts 16, 20. The disc 32 closes apertures 35 in piston 34 and moves it downwards, thereby increasing the oil pressure in chamber 36 and opening the valve 38. Oil flows along passage 60 into the inlet passages 45 and aids the extinguishing of arc 48 by the compressed oil flowing down vent 44 from the arc 47. The slot 26 enables the rod 23 to continue its downward stroke after the contact 16 has stopped moving. Valve 38 only opens when low currents are being interrupted, since the internal pressure of oil is not sufficient to keep it closed, as is the case with high-current interruption. In the latter case, rod 23 is prevented from moving down until the pressure has subsided, the fresh oil from chamber 36 then serving to flush out the arcing region. After this separation, valve 14 in the pressure chamber wall opens to allow the escape of gases. During closing of the breaker, disc 33 moves piston 34 upwards, fresh oil flowing into chamber 36 through apertures 35. In a modification, Fig. 8 (not shown), a modified contact foot, having (i) a chamber corresponding to 36 and (ii) a bracket seat for the spring-urged valve, is fitted. In Fig. 9 (not shown) a modified intermediate contact has lateral and longitudinal passages to permit freer movement of the oil. A further modification of that of Fig. 8, has insulating plates in the pressure chamber to enable the oil to pass in jets on to the arc 47, Fig. 10 (not shown).

Title: Improvements in emulsion-type lubricants
IPC: C10M173/00
Filed: 1956-03-13
Abstract: A lubricant, suitable for use in diesel engines, gas engines, steam engines and engines wherein the lubricant is discharged with the exhaust, comprises a water-in-oil emulsion wherein the oil phase comprises an emulsion-stabilizing agent and the aqueous phase comprises an inorganic base at a concentration greater than 0.03 mols./litre calculated on the aqueous phase.  The oil may be a distillate or residual mineral oil, a synthetic oil (e.g. a diester such as diethyl hexyl sebacate, a silicone or a fluorocarbon) or a fatty oil (e.g. lard oil, cottonseed oil or olein) or a mixture of such oils.  The inorganic base may be a base derived from a metal of Group II of the Periodic Table, especially a hydroxide of such a metal such as barium hydroxide. The emulsion-stabilizing agents mentioned are polyvalent metal soaps of naphthenic or resinic acids, simple condensation products of ethylene oxide derived from at least 5 molecules of ethylene oxide, cyclohexylamine soaps of naphthenic or resinic acids, tallow, rubber latex, guttapercha, cholesterol, wax alcohols, oxidized paraffin wax, casein (in alkaline medium), carbon black, bentonite and blends of alkali or alkaline earth metal sulphonates (M.W. 350-500) with waxes (chosen from natural or synthetic, hard or microcrystalline paraffin waxes, and saponifiable waxes such as montan wax).  The concentration of the inorganic base in the aqueous phase may be greater than the saturation concentration.  In such cases, the aqueous phase may be prepared by cooling a solution of the inorganic base saturated at a high temperature, or with the aid of a sequestering agent such as ethylene diamine tetra-acetic acid.  The oil phase may contain additional ingredients such as antioxidants, detergents, film strength and extreme pressure agents, oiliness agents, antifoaming agents, viscosity depressants and viscosity index improvers.  In an example, a water-in-oil emulsion containing barium hydroxide in the aqueous phase is prepared from mineral lubricating oil, a mixture of synthetic paraffin wax and sodium petroleum sulphonate being employed as the emulsion stabilizing agent.

IPC: G01C21/18
Filed: 1965-02-23
Abstract: 1,138,334. Automatic control of missiles. SPERRY RAND Ltd. Feb.22, 1966 [Feb.23, 1965], No.7865/65. Heading G3R. An auxiliary automatic control system, utilizing stored information computed before take-off, brings the attitude of a missile within the limited capabilities of another automatic control system which then takes over control of the missile's flight path so that the missile reaches a predetermined target. As described, a two-stage rocket missile which takes off from a vertical position is automatically headed in the general direction of a target by information stored in the booster stage before take-off. After separation of the booster stage, a two-gyro platform and a homing eye radar guide the warhead more accurately towards the target. Until just prior to takeoff , the direction which the missile will require to have at the time of booster separation is continuously computed on the ground from a radar tracker and transmitted through synchronous transmission links to a partly caged line-of - sight gyro and roll gyro in the booster. Just before launch the ground computer is disconnected and the roll gyro uncaged. After launch, when the missile has risen vertically and cleared its container, the gyros are rendered effective to steer the missile by controlling liquid injection into the propulsion jet stream. Automatic control of roll attitude is also effective. To prevent self-locking, the line-of-sight gyro is provided with an extra gimbal ring which is unlocked by operation of an electrical contact on the gyro when the missile turns through a large angle. A predetermined time after initiation of the directional control, signals from the line of sight gyro are applied to move the platform in the warhead to a corresponding position so that, at booster separation, the homing eye radar will be aimed approximately in the required direction. The last mentioned control is disabled just prior to booster separation, after which the warhead is controlled by its own homing eye radar and roll gyro.

When. the lamp 15 is lit the voltage across it is high and leads the supply voltage so that bidirectional switch 38 conducts thereby taggering a triac 37. The triac 37 prevents a switch 33 triggering a triac 32 so that the lights 16 and 17 are off. In the event of the supply voltage being, turned off and then on again the lamp 15 remains off until it has cooled sufficiently and a capacitor 36 charges up thereby causing the switch 33 to conduct and the lights 16, 17 to be lit due to the triggering of the triac 32. When the lamp 15 re-ignites the voltage across it is initially insufficient to render the switch-38 conductive but as the lamp warms up the voltage across it increases until the output of an integrator 39, 42 reaches the threshold voltage of the switch 38 before the output of the integrator 34, 36 reaches that of the switch 33 whereupon the lights 16, 17 are extinguished. In a modification a gate signal amplifier is inserted between the switch 33 and the triac 32.
