Title: Improved process and apparatus for de-aerating boiler feed water
IPC: F22D1/30
Filed: 1930-02-22
Abstract: <PICT:0346523/III/1> In a process and apparatus for the deaeration of boiler feed-water, the water, preferably preheated, passes from an inlet 11 through a distributor plate 5, trickles as a thin film over packing 2, in a cylindrical tower 1, and is de-aerated under the reduced pressure created by a steam-injector 10 at the top of the tower; it collects in a sump 3 from which it is removed by a centrifugal or like pump 13.  A drain 15 is provided to empty the sump completely when desired, and a steam inlet 16 is provided to increase the temperature of the feedwater where necessary.  Cold water may be introduced through inlet 8 to condense any steam or water vapour passing into the head 7.  Specification 225,639, [Class 1 (i), Chemical processes &c.], is referred to.

IPC: B60T11/06
Filed: 1935-02-27
Abstract: 452,777. Transmitting-mechanism for brakes. BENDIX, Ltd., and ROBERTS, G. P., King's Road, Tyseley, Birmingham. Feb. 27, 1935, Nos. 6208 and 31.349. [Class 103 (i)] Brakes on front and rear wheels are connected to opposite ends of a floating balance bar and a brake applying effort is applied to an intermediate point, the position of which is varied according to the retarding force when this force has exceeded a predetermined value. A pedal 1 carries a bellcrank 7 having a toothed quadrant 8 meshing with a rack 6 on a balance bar 5 connected to front and rear brake connections 3, 4 respectively. The quadrant is held against the bar 5 by a guard 11 and is held centrally of the bar by a spring 9 until a predetermined braking force is exceeded when the quadrant rolls on the bar and causes greater force to be applied to the front wheel brakes. In a modification, an inertia-weighted lever is adapted to move the balance bar relative to the brake pedal. The pedal and bar engaging by pin and slot. In a further modification, an inertia-weighted lever is adapted to move the point of connection of the pedal and bar by means of a rack and pinion. According to another arrangement an inertiamass may energize a solenoid which displaces the bar and by using a solenoid having a number of axially spaced windings which are successively energized, the movement of the bar may be graduated in proportion to the movement of the inertia-mass.

Filed: 1930-02-25
Abstract: 336,541. Merco Nordstrom Valve Co., (Assignees of Nordstrom, S. J.). Feb. 26, 1929, [Convention date]. Closure members; wedging or jamming.-In a conical plug valve, the plug 11 is held on its seat by a diaphragm 21 pressed against the larger end of the plug by resilient packing rings 23 compressed by a gland 24. A lubricant chamber 26 in the stem 18 is separated from an upper chamber 27 fitted with a screw 28 by a check valve 29, and communicates through passages 30 with upper arcuate grooves 31 on the sides of the plug. Similar grooves 32 at the lower end. of the plug communicate with a chamber 36 beneath the plug through grooves 37. Longitudinal grooves 33 are formed in the casing 10, one on each side of the inflow and outtlow passages 13, 14, the arrangement being such that, when the valve is closed, the ends of the grooves 31, 32 register with the grooves 33 so as to form a continuous channel surrounding each passage 13, 14. By turning the screw 28, lubricant is forced into the grooves and chamber 36, and if sufficient force is exerted the plug is lifted from its seat against the resistance of the diaphragm 21 and packing 23. The chambers 26, 36, are in communication whether the valve is closed, open, or in an intermediate position, but the supply of lubricant to those grooves 33 which are exposed in an intermediate position is prevented.

Title: Improved method of treating the free surface of selenium electrodes
IPC: H01L21/105
Filed: 1947-03-06
Abstract: 623,459. Asymmetrically-conducting resistances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 6, 1947, No. 6341. Convention date, April 6, 1944. [Class 37] In a method of treating the free surface of a selenium electrode with liquid to produce a blocking layer, a liquid solution is used which contains an organic substance that dissolves selenium, in combination with an insulating substance, which is formed by resinification of the organic substance, and which, after evaporation of the solvent, is left in the form of a continuous layer on the selenium. An organic substance, e.g. chinoline, having a resinous constituent is preferably employed, the resin, which ultimately forms the insulating layer, being formed in the chinoline by prior heating of the chinoline in air. Selenium, on an aluminium base-plate, after suitable pressing and heating, is dipped for about one minute in a bath of the prepared chinoline at a temperature of 180‹ C. On evaporation of the chinoline, a layer of resin is left on the selenium. Piperidine, pyridine or triethanolamine may also be used. In the case of pyridine, a separate solvent, e.g. kerosene, may be employed. Specification 539,491 is referred to.

Abstract: 1292382 Seismic energy generators SOC NATIONALE DES PETROLES D'AQUITAINE 10 Feb 1970 [12 Feb 1969] 6364/70 Heading H4D For generating rapidly repeated seismic pulses by the successive detonation of divided sections of an explosive, an explosive mixture in hopper 1 is discharged by pump 2 along a duct 3, compressed gas is periodically injected from conduit 4 to divide the mixture into sections and accelerate them along the duct, a device 17 provides an output signal in response to detection of an explosive section between sensors 18, 19, and the output signal is delayed and used to trigger a high voltage discharge between a duct end electrode 16 and electrode 28 when the explosive section is between the two electrodes. The mixture (examples are specified) comprises a secondary explosive, an oxidizable powder, and a material to lower the electrical resistance of the mixture. A graph 10 and read head 11 provide timing signals for the periodic opening of gas valve 5 and stopping (or by-passing) of pump 2 so as to divide the mixture in duct 3. An annular jet of water passed through pipe 15 entrains the explosive as it leaves duct 3, to keep the explosive section in generally cylindrical form. Device 17 detects a resistance change between electrodes 18, 19 and its output is delayed by monostable 20 and amplified at 21 to trigger a device 23 for discharging capacitors 24 via electrodes 16, 28. The intervals between explosions may be programmed by graph 10 so that the time distribution of the seismic waves transmitted follows a predetermined low. The programme may be optimum for the use of optical or mathematical correlation methods.

Abstract: 693,889. Composite photography. TECHNICOLOR MOTION PICTURE CORPORA. TION. June 1, 1949 [June 30, 1948], No. 6831/52. Class 98 (ii). A method for the production of colour separation records of at least two colour aspects of, and a matter having a boundary corresponding to that of, one component part of a composite scene, comprises the step of photographing the component part of the scene in front of a backing on to two light-sensitive films that are respectively so sensitive to light in such different spectral ranges as effectively to record colour-separation images of two different colour aspects while the said component part is illuminated by light within both of the spectral ranges to which the films are respectively sensitive and while the backing is strongly illuminated only by light in the spectral range to which one only of the films is sensitive, so that freely exposed colour-separation records of said component part are formed on both films and so that the area corresponding to the backing on said one of said films is heavily exposed and that area of the other of the films is underexposed. As shown a foreground scene FG and a backing D are photographed by a beam-splitting camera as described in Specification 382,239 through the film gates of which pass blue and red-sensitive films FNb, FNr and a green-sensitive film FNg. The backing is illuminated by green light by a mercury vapour lamp BG and a minus-blue filter F and the foreground with white light from lamps L. A green filter G is disposed in the light path to the film FNg and a minus-green filter MG in the light path to film FNb; filtering material is carried by one of the films FNb, FNr to absorb blue light. The colour-separation negatives produced may be used as described and claimed in Specification 693,823 in the production of a composite photograph.
