Abstract: 944,537. Electric selective signalling systems. TOKYO SHIBAURA ELECTRIC CO. Ltd. March 30,1962 [April 1, 1961], No. 12667/62. Heading G4H. In a double beam photometer, an attenuator 1, e.g. a photometric comb or wedge or a polarizer, is positioned with respect to a standard beam of light 3 so as to equalize the intensities of the beam 3 and a sample beam (not shown). A digital indication of the sample beam intensity is then obtained by scanning a graduated scale 6 with a beam of light, pulses of light, obtained as a result of scanning the portion of the scale 6 exposed outside mask 9, being sensed by a photomultiplier 20. As shown, scale 6 may comprise reflective facets, and the scanning beam may be obtained from a rotating polyhedral mirror 15. Mirror 21 and photocells 24, 25 serve to produce signals indicating the beginning and end respectively of a scanning operation by one face of mirror 15. Alternatively, the scale 6 may have transparent graduations, scanning may be performed by a rotating slotted cylinder or by a cathode ray tube and, in the latter case signals defining the beginning and end of each scan may be obtained from the time base circuits. The scale 6 may be graduated in a non-linear fashion so that a digital indication which is proportionate to the actual sample beam intensity is obtained when the attenuation characteristics of attenuator 1 is non-linear.

Title: Improvements in or relating to electromagnetic well logging systems
Inventor: DOLL HENRI-GEORGES
IPC: G01V3/28
Filed: 1951-05-25
Abstract: 678,901. Geological surveying. SCHLUMBERGER WELL SURVEYING CORPORATION. May 25, 1951, No. 12364/51. Drawings to Specification. Class 37. In a system for investigating the geological formations traversed by a bore-hole of the kind in which a unit comprising a transmitter coil carrying alternating current and a receiver coil is lowered into the bore-hole and the resistive component of the signal picked up by the receiver coil is transmitted to a recording instrument, one or more supplementary transmitter/ receiver pairs, having different sensitivity from the main pair, are provided and the resultant effect is recorded. The supplementary pairs may be formed by the main transmitter acting with additional receiver coils or by the main receiver coil acting with additional transmitters or both additional transmitter and additional receiver coils may be provided. Preferably the system is such that in air the resultant total pick-up is zero. The arrangements described are designed (1) to make the system unresponsive to conditions close to the bore-hole and so to eliminate the effect of water in the hole and of irregularities in the hole diameter; (2) to make the system unresponsive also to conditions remote from the bore-hole and so to make the response depend solely on conditions in a comparatively thin cylinder coaxial with the hole; (3) to make the system insensitive except to a thin layer extending transversely to the hole; (4) to give the system a response which is a function of the inhomogeneity of the surrounding material in a transverse direction. The Specification indicates the manner in which the distances between the coils and their areas and ampere turns are to be selected to produce the desired effects.

Title: Improvements in or relating to the removal of condensates from fuel gas before entering gas distribution systems
IPC: C10K1/00
Filed: 1949-05-10
Abstract: 680,285. Gas purifying processes. MARKISCHE STEINKOHLENGEWERKSCHAFT, AND HOLTHAUS, P. W. July 25, 1950 [May 10, 1949], No. 12407/49. Class 55 (ii). Before admission to a distribution, main fuel gas is compressed to not more than twice the mains pressure, cooled and then expanded to effect the separation of condensable constituents, e.g. water and naphthalene. Or, the gas raised to higher than mains pressure is cooled to about atmospheric temperature and expanded to about mains pressure, the temperature remaining, above the freezing point of the contained water. Gas from a main 1 is compressed in, e.g. a multi-stage compressor 2 having intermediate cooling stages and the heat generated in the final stage is extracted in water coolers 3, 5, condensate being removed through drains 4, 6. The gas is further cooled in exchanger 7 by indirect contact with the expanded gas and after further separation of condensate by a drain 8 passes to an expander 9 shown as coupled with the compressor, and is finally delivered to the main 11 through a further condensate' drain 10 and the exchange 7. The admission to the expander may be controlled in accordance with the temperature of the expanded gas. In an example, the gas temperature at drain 6 is 35‹C., at exchanger 7, 20‹C. and after expansion, 5‹C. ; this fall of 15‹ is effected when the main pressure is 10 atmospheres by compressing the gas initially to 12 atmos.

Title: Regulation of catalytic activity
IPC: B01J21/16
Filed: 1940-08-01
Abstract: 546,822. Catalytic agents. HOUDRY PROCESS CORPORATION: Aug. 1, 1940, No. 12465. Convention date, Aug. 12, 1939. [Class 1 (i)] Siliceous catalysts for reactions such as the conversion of hydrocarbons are treated at temperatures of at least 600‹F. with superheated steam to reduce undesired activity or to reduce the tendency to promote formation of carbonaceous deposits relatively to the desired activity. The steam may be diluted with a dry inert gas. The temperature should not exceed that at which heat alone adversely affects the catalyst, and the partial pressure of the steam, the temperature, and the duration of treatment depend upon the effect required. Typical conditions are one atmosphere at 1000‹F., 2 atmospheres at 800‹F., or 3-5 atmospheres at 600‹F. and a duration of 12 hours or less. At higher temperatures subatmospheric partial pressures are preferable, e.g. <SP>1</SP>/ 40  to <SP>1</SP>/ 5  atmosphere at 1400‹F. Specifications 519,808 and 539,284 are referred to.

Filed: 1924-05-24
Abstract: 235,371. Schneider, H. May 24, 1924. Systems for alternating - current motors; speed maintaining systems. - In electrically operated flyer spinning- frames the main shaft 31 of the machine is driven by an electromotor 46 and is provided with a fly-wheel 30, so that the rollers are started and stopped gradually and under-twisting when starting the frame and over-twisting when stopping are obviated, and the flyer motors 4 are fed from a supply 37 through a slip-ring motor 36 the rotor of which is coupled to the main shaft 31. When starting the rotor of the motor 36 is at rest and current of full frequency is supplied to the flyer motors 41. The motor 46, which may have a squirrel-cage rotor, is also fed from the supply 37, and, as the shaft 31 is coupled to the rotor of the motor 36, the frequency of the current supplied to the flyer motors is reduced after starting. The torque on the rotor shaft of the motor 36 assists in driving the rollers through the gearing 35, and as the bobbins become fuller and the flyer motors require a greater current this torque may exceed the power requirement of the drawing-rollers and the machine 46 will run as a generator. To obviate a reduction of speed as the bobbins fill an increase of voltage or of frequency is imparted to the current of the flyer motors. For these purposes a potential regulator may be inserted in the circuit between the slip rings 38 and the bus-bar 40, or the gearing such as a cone belt drive. Instead of a threephase machine 46, a continuous current machine may be employed or the shaft 31 may be connected to a line shaft revolving at a uniform speed. If it is desired to feed the flyers with current cf higher frequency than that of the supply system 37 two phases of the stator of the machine 36 are interchanged and its rotor is driven, the machine 46 operating in this arrangement permanently as a motor.
