Patent GB-603507-A (GB)
Title: Improvements in and relating to electric signal flashing systems
IPC: G08B5/38
Filed: 1945-10-22
Abstract: 603,507. Auxiliary lighting systems. LONDEX, Ltd., and BESSON, A. P. Oct. 22, 1945, No. 27760. [Class 38 (iv)] [Also in Group XXXVIII] Failure of a main visual or audible signal flashing circuit de-energizes an electromagnetic switch to complete an auxiliary flashing signalling circuit, the switch normally being energized over an impedance shunting the main flasher contacts but passing insufficient current to operate the main signal when these contacts are open. The impedance may be a choke or an auxiliary winding of the switch. As shown in Fig. 1 a main signalling lamp 5 is operated by a flasher 6-8, the contacts 4 of which are in series with the lamp and with an energizing coil 1 of an electromagnetic switch 2 controlling an auxiliary signal lamp 3. Switch 2 is opened by coil 1 when the flasher contacts close and is maintained open when these contacts open by an auxiliary winding 9 shunting the contacts or both the contacts and the coil 1. Winding 9 limits the current in the main circuit to a value insufficient to light lamp 5. Failure of lamp 5 prevents energization of coil 1, with consequent closure of switch 2 and connection of lamp 3 to the flasher. A modification is also described in which the winding 9 is replaced by a choke connected across contacts 4. Remote indication of the substitution of the auxiliary circuit may be provided by a further auxiliary non- flashing signal.

Title: Thyristor switching circuits
IPC: H03K17/72
Filed: 1967-06-16
Abstract: 1,118,507. Inverting. INTERNATIONAL STANDARD ELECTRIC CORP. 16 June, 1967 [22 June, 1966], No. 27788/67. Heading H2F. [Also in Division H3] Commutating of a thyristor is effected by discharging a capacitor through a series circuit comprising an inductor and a resistor, the resistor being shunted by a switch so arranged that the capacitor charges slowly (e.g. to prevent ringing) and discharges quickly. Fig. 2 shows an invertor in which when T 1 is conducting the commutating capacitor C2 charges through D2 and resistor R2. When T2 is rendered conducting C2 discharges through D4 into an inductor L producing such a voltage thereacross as to switch off T1, R2 prevents the build up due to oscillation of the voltage across C2 to a value more than twice the supply voltage but is prevented from affecting commutation because it is shunted by D4.
Patent GB-711041-A (GB)
Title: Improved fibrous lubricating grease
IPC: C10M169/00
Filed: 1950-11-14
Abstract: Mineral lubricating oil is mixed with a soap selected from the group consisting of lithium soaps, mixtures of lithium and calcium soaps and mixtures of lithium and strontium soaps of unsaturated fatty acids, the mixture is heated to the melting point of the soap, or slightly above then cooled with agitation to the transition temperature, and the grease mixture is allowed to cool further without agitation.  The total amount of soap may be preferably from 5 to 50 per cent. by weight based on the total composition.  It is preferred that the unsaturated fatty acids have an iodine value of 75 or more.  The greases are prepared by heating a mixture of the fatty acids with about a quarter of the mineral oil to about 150 DEG F. and then adding the lithium hydroxide, mixed if desired with calcium or strontium hydroxide, as a boiling water solution, or as a water slurry in the case of the mixed bases.  The temperature is raised to 220 DEG F. and another quarter of the mineral oil added.  The mixture is dehydrated at 220 DEG  to 240 DEG F., then the remainder of the oil is added at about 300 DEG F. and the temperature is raised to the melting point of the soap or slightly above.  The homogeneous mixture so obtained is cooled to the transition temperature with constant agitation such as milling and then cooled further to handling temperatures without agitation.  In an example (all percentages by weight) 15.0 per cent. of cottonseed fatty acids and about a quarter of the total amount (82.25 per cent.) of mineral oil of viscosity S.U.S. 900 at 100 DEG F. and V.I. 45 are heated to 120 DEG F. and 0.85 per cent. of lime (68 per cent. CaO) added and cooked in.  At about 170 DEG F., 1-90 per cent. of lithium hydroxide monohydrate is added as a boiling water solution and the temperature raised to 220 DEG F.  A further quarter of the mineral oil is added to facilitate stirring and the mixture dehydrated at 220 DEG -240 DEG F.  Further heating is applied and the remainder of the mineral oil is added at 300 DEG F.  The temperature is raised to 320 DEG F. and held there until the soap curds melt to give a homogeneous fluid mixture.  The grease was stirred while cooling and samples withdrawn at different temperatures for testing, the results being reported.

Title: Improvements in or relating to reducing valves
Inventor: MARTIN FRANK
IPC: G05D16/10
Filed: 1965-06-30
Abstract: 1,098,996. Valves. HALE, HAMILTON (VALVES) Ltd. June 9, 1966 [June 30. 1965], No. 27803/65. Heading F2V. The pressure-reducing valve member 31 controls flow from inlet 25 to outlet 27. The valve member is fast with a piston 34 subject on its underside to the outlet pressure. The other side of the piston (chamber 14) can be subjected to a loading pressure supplied from the inlet via passages 35, 38 through a manually operated valve 39 which is then set to seal the passages. In another position valve 39 vents the chamber 14 to allow the reducing valve to close. Excess inlet pressure after closing the valve member 31 lifts it sufficiently to open a lower vent passage 28 and connect the outlet to atmosphere. In a modification, Fig. 2 (not shown), the reducing valve is loaded by a spring. In another modification where the valve 39 is omitted the piston is pressurized from passage (35) through a needle valve (87) which is then closed to seal the chamber. The valve member has a cylindrical part 23 with an 0-ring which enters a cylindrical throat 15 to close the valve. A taper 31 on the valve member in co-operation with a tapered entry 32 of the throat defines a reducing orifice.

Means for adjusting the calorific value of a mixture of gases, e.g. a mixture of coal gas and producer gas, comprises a sampling point near to the point at which the gases are mixed and from which a continuous sample of the mixed gas is drawn-off by an extractor having a water-vacuum pump secured in the top of a container and arranged so that the drawn-off gas is washed by the water from the pump, an iron oxide or similar purifier for the further purification of the washed gas, and a controlling calorimeter to which the purified gas sample is supplied and which actuates a valve controlling the supply of a constituent of the mixture in accordance with the calorific value of the mixture. An electrostatic detarrer may be placed between the sampling point and the water-vacuum pump.

Abstract: 1390226 Films of uniform thickness CELANESE CORP 15 June 1972 [28 June 1971] 27977/72 Heading B5B Biaxially drawn film of substantially uniform thickness across its width is made by extruding a molten thermoplastic through a die 12 to obtain a film 21 and biaxially drawing the film at 15, 16, while supplying heat along the die orifice by a plurality of contiguous heaters 13, each occupying not more than three inches of the die orifice length, and controlling the heat supplied by each heater by the magnitude of the signal generated by a thickness gauge operating at a corresponding point on the biaxially drawn film to maintain substantilly uniform the thickness of the biaxially stretched film at points across the width thereof corresponding to the heaters. As shown, the heat supplied by each heater is controlled by the magnitude of the signal generated by a traversing beta ray thickness gauge 17 operating at a corresponding point on the biaxially drawn film. The output of gauge 17 is transmitted to control station 18 which transmits a signal to control unit 19 whereby the voltage applied to the electrical resistance heater 13 corresponding to the particular zoneof the drawn film being carried by gauge 17 can be adjusted. Die zone heaters (27), Fig. 2 (not shown), contained within the die body 12 may also be used, and the width of the die opening 24 may be adjusted by a plurality of die bolts (26). The melt flow profile is finely controlled by the heaters 13, which have a preferred width of 0À5 to 2 inches. Polyethylene terephthalate films may be so processed, and biaxially drawn to 2À8 to 5À0 times in each direction.
