IPC: B01F5/00
Filed: 1932-03-04
Abstract: 380,723. Aerating-apparatus ; valves. MILLER, J. S., 1443, Manhattan Avenue, Hermosa Beach, California, U.S.A. March 4, 1932, No. 6615. Convention date, March 21, 1931. [Class 14 (i).] Valve-apparatus, without a mixing chamber, for aerating liquids, comprises a gas inlet valve 36, water inlet 12, and a conical valve 59 controlling the passage of mixed water and gas to a faucet connected to the spigot 66. A spring-pressed diaphragm 21 with a metal centre 18 is secured in a chamber 31 having a byepass 52, 49. When the faucet is opened the valve 59 is opened by the water pressure and gas escapes from the chamber 31, thus allowing a spring 16 and the water pressure combined to force the diaphragm to the left and open the valve 36. Gas under pressure then passes from the container along. the byepass 49, through a nozzle 46 and, together with water, through holes 63 in the valve 59, causing the water to be aerated.

Title: An improved tubing and means for producing same
IPC: F16L11/24
Filed: 1919-03-19
Abstract: 151,298. Blaisdell, F. E. March 10, 1919. Flexible p i p e s . - Tubings or containers for oil, petrol, &c., are formed by shaping on suitable formers layers of gut formed from the intestines of pigs, sheep, or oxen, with or without other layers of fabric, rubber, or the like. The tubing may be formed on corrugated formers, or may be corrugated by winding around spirals of wire, and the outer layer may be pressed by a wire or cord to a corrugated former, the corrugated tubes being separated from these wires, or the wires being allowed by remain as armourings. The intestines are preferably cleansed, passed through a wringer, and immersed in a preparation of glycerine, and fish glue, or gelatine. These are superimposed on each other by drawing them one over another on a tubular shell 1, held by tapered centres 2, 3, over which the intestines are in the first place threaded, and the tube is pressed on the shell 1 by hand pressure, and allowed to dry. The shell 1 is preferably coated with wax, e.g. bees-wax, which is melted to allow the tube or container to be detached. For forming corrugated tubes a corrugated former may be used, or a plain former 13 with a detachable spiral of wire 14. The tube 15 may be pressed by an external spiral 16, and the spirals 14, 16 may be separated from the finished tube, or remain connected with it to serve as armouring. The tube &c. may be formed by spirally winding, or by spirally winding combined with the process described above, and an intermediate strengthening layer of fabric may be employed, and an outer layer of rubber may be used. The tubes &c. may be rendered impervious to moisture by treatment with a metallic bi-chromate, and they may be coated with a flexible varnish, e.g. a solution of pyroxylin, and a softening-agent such as oil.

Title: Improvements in lubrication distribution
IPC: B61K3/02
Filed: 1945-03-20
Abstract: 589,225. Lubricating. TECALEMIT, Ltd., and LE CLAIR, C. C. S. March 20, 1945, No. 7043. [Class 12 (iii)] The flanges or tyres of the wheels of a rail vehicle are supplied with lubricant while travelling on a curve, at the outer rail, under the control of a mass adapted to move transversely of the vehicle under the action of the centrifugal force arising from rounding the curve, the mass being arranged between and controlling two normally closed valves one of which can thus be opened at a time to allow oil or mixed oil and compressed air to flow to the wheel tyre or flange. The mass may merely slide along guide rails or may be a pendulum, either inverted or suspended normally. As shown a normally suspended pendulum 3 swinging transversely of the vehicle on which it is mounted swings to the outer side when rounding a curve whereby a valve 7 at the outer side is opened to admit compressed air from a train-service pipe line 14 to an oil tank 27 whereby oil is forced to an atomizer 19 and mixed with compressed air for delivery by a pipe 29 discharging an oil mist adjacent the tyre and flange of one or more wheels running on the outer rail of the curve. The pendulum is neutralized by the heads 37 of spring-urged rods 36 sliding in a bracket piece 40 and the swing is limited by adjustable stop screws 34 provided on the valve casing 5. The pendulum is damped by a link connection 49 to a dash-pot comprising an apertured plate 46 moving in an oil cylinder 45. Magnetic damping may be used.

Title: Improvements relating to the elimination of interference in wireless systems
IPC: H04B1/66
Filed: 1937-03-10
Abstract: 493,837. Transmission systems ; utilizing light. HENROTEAU, F. C. P. March 10, 1937, No. 7076. Convention date, Feb. 11. [Class 40 (iv)] [Also in Group XL] The effect of interference in wireless transmission is reduced by dividing successive portions of a message into fragments which are transmitted simultaneously on different carriers and are expanded in duration to'a multiple substantially equal to the number of fragments. The modulation frequencies are thus reduced at the transmitter and restored at the receiver, and the interference currents are shifted to frequencies which are inaudible or which can be eliminated by a tone filter. The speech currents are fed to a recording cathode-ray tube 3, whereby the signals are represented by parallel bands 4 on the fluorescent screen, and these bands are projected on the sensitive screens 6 of a corresponding number of scanning cathode-ray tubes 7, the output currents of which are fed to the modulators. As shown, the ten parallel bands are each scanned in the same time that the whole are recorded, so that the modulation frequencies are reduced ten times. At the receiver, all the modulation frequencies are fed to a single recording tube 9 to produce a set of parallel bands which are projected on the sensitive screen 11 of a tube 12 which scans them in succession at the same speed as that of the tube 3 to restore the original frequencies. It is desirable to employ two recording tubes 9, 9a and two scanning tubes 12, 12a with their control grids connected to battery by a commutator 16 to render them operative alternately so that each portion of the message is completely recorded before the tube 12 or 12a begins to scan it. A similar duplication of the apparatus at the transmitter is necessary to work with the duplicated apparatus at the receiver.

Title: Improvements in or relating to arrangements for modulating electric carrier wave oscillations
Inventor: HARLING DENIS WILLIAM
IPC: G01R29/06
Filed: 1954-03-11
Abstract: 771,366. Modulating systems. GENERAL ELECTRIC CO., Ltd. March 4, 1955 [March 11, 1954], No. 7131/54. Class 40(5) The system in which a carrier is modulated by a video signal in a balanced modulator, the depth of modulation is maintained constant by controlling the D.C. level of the modulator in accordance with the peak value of the output. A constant amplitude carrier is generated at 3. and applied to the balanced modulator 1. Video signals are applied between points 13, 18 by a bridge consisting of valve 7 and resistors 11, 12. and valve 21 and resistors 19, 20. Valve 7 is a cathode follower to which the video signals are applied with positive going synchronizing pulses, and which varies the bridge balance to apply the modulating signals to the modulator. Valve 21 is also a cathode follower, which varies the bridge balance to adjust the mean carrier level. In the absence of modulating signals, the standing current of valve 21 is adjusted by a biasing potentiometer 35 to sufficiently unbalance the bridge to so bias the modulator 1 as to give a desired unmodulated carrier amplitude. The modulated output is fed back to an amplifier 24, 25, tuned to the carrier frequency, and a portion of the original carrier is also added from a hybrid transformer 4 so as to reduce the depth of modulation of the feed back signal and prevent incorrect control of heavily overmodulated signals. A further amplifier 26 precedes a peak detector 33, which, via low pass filter 34 controls the cathode follower 21 so as to reset the bridge balance in such a sense as to oppose any change in the peak potential pf the modulated carrier, thereby maintaining the modulation ratio at a predetermined value. The modulated carrier is passed to a band-pass filter to select one side-band and a vestigial part of the other, .and then applied to a network having a frequency/amplitude response such as to reduce the amplitude of frequencies near the carrier. Specification 699,539 is referred to in the Provisional Specification.
