Title: Improvements in or relating to a starting and operating circuit for high pressure vapor arc lamps
IPC: H05B41/04
Filed: 1958-03-25
Abstract: 865,532. Supply systems for space-discharge lamps. ENGELHARD HANOVIA Inc. March 25, 1958 [June 5, 1957], No. 9594/58. Class 38 (4). A starting and operating circuit for highpressure vapour arc lamps comprises a resistor, composed substantially of nickel in series with the parallel combination of a capacitor and a lamp, with the coil of a pulse system connected in a supply lead between the capacitor and the lamp. An alternating supply is fed via the leads 1, 2 and the resistor 4 to the lamp 3 and the transformer 13. Initially the resistor 4 has a low value but the voltage across the lamp 3 is too low to strike an arc. The voltage on the secondary 12 of the transformer 13 causes sparking across the gap 11 and radio frequency energy is fed to the lamp 3 via the capacitor 8, the R. F. transformer 6, 7 and the capacitor 5. The R.F. energy ionizes the vapour in the lamp and starts it operating, whereupon sparking at the gap 11 ceases since the volt drop across the lamp, and hence the voltage applied to the transformer 13, is too low. The heavy current taken by the lamp 3 causes the resistance of the resistor 4 to rise until the lamp reaches its optimum condition. The resistor 4 may consist of a helix or a coiled coil wound on a ceramic former.

Title: Improved methods of processing polytetrafluorethylene and products therefrom
Inventor: VINCENT RUSSELL SWALE
IPC: C08J11/06
Filed: 1950-04-20
Abstract: Polytetrafluoroethylene of small particle size in a finely divided or coherent porous form is produced by mixing coarse grains of polytetrafluoroethylene with a suitable binder to produce a plastic mass, milling this mass until the particles are reduced in size to the desired extent and then removing the binder.  Suitable binders are thermoplastic viscous sticky substances and oily liquids which are stable at the elevated temperatures which exist in the compounding process, and which can be removed from the polytetrafluoroethylene after milling, such as polyisobutylene and mixtures thereof with toluene or mineral oil, natural or synthetic rubbers, silicone fluids, resins, and rubbers, polymethyl methacrylate which is preferably used in conjunction with toluene, ethyl cellulose, and fluorocarbons such as perfluorinated benzotrifluoride polymers, polymers of trifluorochloroethylene, and highly fluorinated mineral oils.  The binders are removed from the compositions by solvent extraction, thermal decomposition, or chemical attack.  The process may be applied to scrap polytetrafluoroethylene such as that obtained from pressure moulding or partial sintering, and may also be used to incorporate in polytetrafluoroethylene finely divided materials such as metals, carbon, and pigments such as cadmium seleno-sulphide, cobalt green, and chrome green.  The finely divided or coherent porous polytetrafluorethylene may be used in coating and insulating applications, in the production of shaped articles, in paper making processes, as filters, and as substitutes for paper in electrical insulation.  Specification 706,089 is referred to.

Title: Improvements in or relating to gelatin dynamites
IPC: C06B25/30
Filed: 1940-06-04
Abstract: 545,410. Explosives. HERCULES POWDER CO. June 4, 1940, No. 9789. Convention date, April 13. [Class 9 (ii)] Cellular carbonaceous material which has been treated with synthetic heat hardening resin to stiffen the cell walls is used in the preparation of gelatine dynamites whereby the resultant explosive offers increased resistance to high pressures so as to preserve its sensitivity and plasticity after prolonged immersion at great depths in water or other liquid. The carbonaceous material may consist of ground cork, balsa, bagasse, bongo wood, hemp hurds, and the like. The general method of treatment consists in impregnating the material with a synthetic resin such as the urea aldehyde, phenol aldehyde, or thiourea aldehyde type, and then heathardening. In a typical method, a mixture of cork and urea in aqueous formaldehyde solution is heated to condense the formaldehyde resin and dry the cork at a temperature of 70-100‹C. The resin-impregnated cork is then submitted to further heating at 100‹C. for ¢ to 1 hour, or for shorter periods at temperatures up 150‹C. to harden the resin. The urea may be mixed with the cork before adding the formaldehyde, or the urea-formaldehyde solution may be sprayed on the hot cork. As a further alternative, the carbonaceous material may be treated with a partial condensation product of urea and formaldehyde in aqueous or organic solvent (e.g. ethyl alcohol), the solvent evaporated, and the resin heathardened, other suitable hardening-agents mentioned include a formaldehyde solution of cresol with a catalyst such as hydrochloric acid, and a combustion of chlorinated rubber and a heat-hardening phenol formaldehyde resin. The Specification includes numerous comparative tables setting out the effect of the cell-hardening on the relative immunity to density-change resulting from external pressure, resistance to water penetration, and the consequential larger range of sensitivity of the improved explosive. The Specification also describes a method of testing which is exemplified as follaws. Three sticks of dynamite are placed end to end in a steel tube having end-closures in which a water filling is subjected to pressure for any described period, one end-stick being fitted with a standard blasting cap. The tube is laid on the ends of a spaced series of lead cylinders each covered by a steel disc of corresponding diameter, the completion (or otherwise) of the detonation-effect being registered by the extent of the resultant compression in the lead cylinders along the line of the tube. The low-density carbonaceous materials may be prepared as described in Specification 546,382, [Group IV].

Title: Detector for spot welding zone
Inventor: FURUSE ICHIRO
IPC: G01N27/82
Filed: 1987-01-08
Abstract: PURPOSE:To detect whether or not a spot welding zone is proper with high detection accuracy by setting a magnetizer and a magneto-electric converting element which detects leak magnetic flux opposite the spot welding zone, and comparing the signal of the magnetoelectric converting element with a preset condition signal. CONSTITUTION:The magnetizer 1 is arranged opposite the spot welding zone B of a body A made of a metallic material to be inspected and the magnetoelectric converting element 4 is arranged between its magnetic poles and assembled in one body. Then when the magnetizer 1 is put close to the body A to be inspected and magnetizes it, magnetic flux 3 travels in parallel to the surface of the body A to be inspected. The magnetic flux 3 leaks in air at the spot weld zone B owing to the difference in magnetic permeability between the metallic material and spot welding zone B of the body A to be inspected and is converted by the magneto-electric converting element 4 into an electric signal, and the output signal 4a is inputted to an electric circuit K. Further, the preset condition signal K1 is inputted to the electric circuit K and compared with the output signal 4a to detect the number of welding spots, whether the position is proper or not, etc. Thus, the leak magnetic flux is detected, so the spot welding zone is accurately detected.

IPC: G02F3/00
Filed: 1993-01-07
Abstract: PURPOSE:To easily perform the positioning of the irradiation spot of a photoconductive switch by canceling the field through by using a capacitor provided with a value equal to the parasitic capacitance of the photoconductive switch or a third photoconductive switch as a dummy. CONSTITUTION:The output amplitude of the photoconductive switch 13 becomes larger than that of the field through from the capacitor 12 since a photoelectric current in accordance with an application voltage flows into the photoconductive switch 13, and a voltage of difference between them appears at an output terminal 22. Also, when an electrical signal generated at the photoconductive switch 11 does not arrive at the switch 13, no voltage is applied to the switch 13, and no voltage appears at the output terminal 22 even by irradiating the switch 13 with light. In other words, a pulse voltage appears at the output terminal only when the pits of optical digital data signals A, B irradiating the switches 11, 13 are superimposed. Therefore, the influence of the field through can be reduced by a means like a circuit, which dispenses with the fractionization of the photoconductive switch.
