Title: Measuring the Temperature of a Selected Area of a Body
Inventor: CARLSON GERALD JOSEPH
IPC: G01J5/60
Filed: 1968-01-22
Abstract: 1,187,331. Temperature measuring. GENERAL ELECTRIC CO. Jan.22, 1968 [April 21, 1967], No.3325/68. Heading G1A. [Also in Division G3] The temperature of an inaccessible surface of a body is measured by investigating two spectral bands of the radiation from a proximate accessible surface by means of a fibre optic guide, the transmitted radiant energy being converted into a series of electrical pulses alternate ones of which represent the amplitude of the respective spectral components and the pulses representing the respective bands being separated and compared by a comparison device in which adjustment to give a null output provides the temperature indication. The temperature of the hottest spot on a cutting tool 10, Fig. 3, is determined by such apparatus, the fibre optic guide being inserted in a hole in the bottom of the tool beneath the hot spot and its remote end applying infrared to a detector 35 through a disc 31 comprising a pair of rotating different filters 32, 33. The pulses are separated by an FET switch 43 controlled by pulses from an arc-responsive presence or absence optical system 37-40 associated with disc 31, and applied to differential amplifier 51 through peak-topeak detector 46 and LP filters 45, 47. The temperature is indicated by a nulling unit 48. The fibre optic may be let into a hole in the cutting member support opposite a hole beneath the hottest spot in the cutting member itself and separate optics within a milling cutter may be air coupled to a fixed fibre optic guide. The output may be used to regulate tool cutting speed to obtain a desired tool temperature. The guides may be of glass or quartz fibres according to the temperature to be measured, the former being used in conjunction with gallium arsenide or cadmium sulfide detectors, and the latter with lead sulfide or indium arsenide. The filters may be made to reciprocate or alternatively the end of the light guide may be moved.

Title: Filtering method
IPC: B01D37/04
Filed: 1959-01-30
Abstract: 862,915. Filters. LONZA ELECTRIC & CHEMICAL WORKS Ltd. Jan. 30, 1959 [Feb. 1, 1958], No. 3398/59. Class 46. Liquid, containing solids, is withdrawn from a vessel T by a pump P, Fig. 2, through a valve V in the position shown, and discharged to a filter casing F. The pressure suffices to force filtrate from a collecting pipe Z to an elevated storage container B. At intervals, and for periods amounting to, e.g., 1/3 down to 1/1000 of the intervening filtering time, the valve V is moved to the right electrically under the control of clockwork U, so that the passages through the valve occupy the dotted-line positions. Thereupon the pump withdraws liquid from the filter casing F and returns it to the vessel T. During such periods of reversal, portions of the filter cake are lifted from the filter membrane, and cracks are formed through the filter cake so that, upon resumption of filtering, additional unfiltered liquid will come into direct contact with the membrane at these. places, and filtrate will flow through, thus increasing the filtration rate. The result is that the filtrate volume remains proportionate to the filtering time (curve b, Fig. 1) instead of falling off with increasing filtration time (curve a, Fig. 1). The pressure differential may be from 0À1 to 10 atmospheres, and the duration of each reverse flow may be from 0À2 to 10 seconds.

Filed: 1942-03-18
Abstract: 556,157. Converting. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., STEVENS, S. A., and WALKER, A. H. B. March 18, 1942, No. 3587. [Class 38 (ii)] A.C. is converted to D.C. or vice versa by synchronously operated switches such as AP, BP in combination with dry surface contact or other type of rectifiers which take the current only at the period of commutation and are operatively included in the circuit for short periods just before the closing and just after the opening of the main contacts AP. Fig. 3 shows a rectifying arrangement in which during the greater part of the positive half-wave, current flows to the terminal 4 through the closed switches AP, BP. As the zero point approaches, AP opens so that the current passes through the rectifier RP near this point. During the greater part of the negative half-wave current flows to the terminal 4 through the switches BN, AN, but at the zero point, AN opens so that it passes through the rectifier RN. In a three-phase arrangement, diagrammatically shown in Fig. 9, two "lead" rectifiers PR1, NR1 and two "lag" rectifiers PR2, NR2 act for each phase in turn. The three phases are represented by the vectors VA, VB, VC each of which carries the current for approximately 120 degress and leads it during the greater part of this time directly to the terminal 4 ; but at the beginning of each 120 degrees period, the rectifier PR1 is inserted in the circuit and at the end of each period the rectifier PR2 is inserted.

Abstract: 696,916. Controllers; mechanical switches. WOOD & CO., Ltd., H. Feb. 7, 1952 [Feb. 15, 1951], No. 3638/51. Classes 38 (iii) and 38 (v) [Also in Group XXX] A safety device for an electrically driven conveyer comprises a hand-operated switch 23 in series with a time delay switch 17 which opens at a predetermined period after the closure of the switch 23, both switches being connected in a pilot circuit for operating the starting switch of the motor driving the conveyer. The switch 17 is also in parallel with normally open contacts of a relay energised by a generator driven by the conveyer so that; if the conveyer fails to attain its operating speed within the predetermined period, the pilot circuit is opened and the conveyer is stopped. The switch assembly has a handle 19 which is held in its inner position by means of a spring detent, and, when the handle is pulled out, a switch arm 21, rigid with the handle, closes the switch 23 to complete the pilot circuit. Movement of the handle releases the spring-actuated plunger of a time delay device which first causes arm 14 to open switch 18 and insert a holding resistance in the pilot circuit. Further movement of the plunger effects the opening of the switch 17 by means of arm 13. Specification 674,332 is referred to.
