Title: Electron discharge device
IPC: H01J31/36
Filed: 1963-05-03
Abstract: 1,038,031. Cathode-ray storage tubes; television pick-up tubes. WESTINGHOUSE ELECTRIC CORPORATION. May 3, 1963 [May 31, 1962], No. 17620/63. Heading H1D. In a cathode-ray tube in which a charge pattern is produced and stored on a target 30, electrons are projected on to the target with an energy corresponding to that portion of the secondary emission curve of the target in which secondary emission increases with an increase in potential between the electron source 40 and target 30 to cause differential secondary emission from the target elements and consequent enhancement of the strength of the charge pattern. The invention may be used in vidicon, iconoscope or image orthicon camera tubes or in image display storage tubes. As shown, the device is sensitive to thermal radiation and comprises a faceplate 13 of sapphire, calcium fluoride or barium fluoride, and a target 30 including a transparent conductive layer 32 and a photo-conductive layer 33 of antimony trisulphide, arsenic trisulphide or arsenic triselenide supported by a glass or aluminium oxide film 31. A charge pattern on target 30 is enhanced by a flood beam from gun 40, or by a scanning beam, which may be used sequentially with the writing and reading phases of the tube, or simultaneously with the writing phase.

Divided out of 433,372. [Class 111] Rotary sludge-collecting apparatus or a platform M extending over a settling basin is supported, wholly or in part, by a drum H open at the bottom and rendered buoyant by compressed air. The drum surrounds a central pillar J provided with guide rollers H<1> and rollers J<1> on which the drum rests if the air pressure fails. An upward extension K of the pillar J has ducts for the supply of air to the drum from a compressor K<3> and of lubricant for the rollers H<1>, J<1>. The compressor K<3> and a motor for driving the rotary sludge collector by means of a spur gear L on the drum may be carried by the platform M or arranged at the side of the tank. The upward movement of the drum is limited by a bearing ring L<1> which engages through rollers L<2> with a bearing- ring K<5> adjustable vertically on the extension K. The rollers J<1> may be mounted on hydraulic jacks so that they can be adjusted vertically and can be used to lift the drum and its load. A float in a tube O<1> open at its lower end within the drum and connected to a counterweight in a tube O<2> operates a switch to stop the motor if the buoyancy of the drum fails. Air or oil on the surface of the liquid in the drum can be .drawn off through a pipe Q which extends downward through the column J. The pipe Q or its inlet end may be adjustable vertically.

Abstract: 1314101 Controlling atmospheres by sorption SULZER BROS Ltd 16 April 1970 [17 April 1969] 18261/70 Heading B1L The atmosphere of a closed chamber (not shown) which contains fruit or vegetable matter is controlled by regulating the amount of CO 2  present. The process employs a cyclically operated one or two bed adsorptiondesorbtion system wherein desorption is carried out by admitting atmospheric air via line 6 and valve 4 to the adsorber 1. At the commencement of adsorption the atmosphere remaining in the adsorption unit 1 after the previous desorption step is expelled to outside via line 12 before the adsorber is reconnected to the chamber via valve 8 and line 11. Likewise at the commencement of the desorption step the stripped gas remaining from the previous adsorption step is recycled to the chamber before the adsorber is connected to atmosphere. Both valves 4, 9 are controlled by an activator which incorporates a delay, e.g. electrical, mechanical, pneumatic or hydraulic so that the valve 9 is operated after the valve 4. The flow may be counter or co-current. The adsorbent may be a zeolite, activated charcoal or potash solution supported on gravel. The desorbing air may be heated by heater 7.

Title: Improvements in or relating to radar systems
Inventor: DILL EVERETT CHARLES
IPC: G01S13/70
Filed: 1952-07-18
Abstract: 717,794. Radar. WESMTINGHOUSE ELECTRIC INTERNATIONAL CO. July 18, 1952, No. 18278/52. Class 40 (7) In an automatic range tracking radar system comprising a transmitter and a receiver in which early and late gate pulses displaced equally with respect to time on either side of an echo pulse are generated means are provided for preventing the receiver from locking in on pulses directly received from the transmitter. The means include a generator for generating suppressor pulses which cancel out the early gate pulses when these occur at the same time as the directly received transmitted pulses. In one embodiment trigger pulses are fed to square wave generator 10 feeding saw tooth generator 11 whose output is clipped at 12 in accordance with the input form unit 20 to give a variably timed pulse amplified at 13 and supplied to early gate pulse forming circuit. 14. Circuit 14 supplies early gate pulses to early gates coincidence circuit 15 and to late gate pulse generating circuit 16. This supplies late gate pulses to coincidence circuit 17 which together with circuit 15, is fed with the received pulse signals. The outputs of the coincidence circuits 15 and 17 are fed to unit 19 which determines the potential it is necessary to apply through D.C. amplifier 20 to clipping unit 12 to maintain the gate and echo pulses in coincidence. When the echo pulse being followed approaches zero range it will overlap the directly received and much stronger transmitter pulse and lock on to it instead of following the echo when the range of the object giving rise to it once more increases. To prevent this occurring suppressor unit 18 generates a suppressor pulse coinciding with the transmitted pulse in time and of inverse polarity to the early gate pulse. This is applied to the coincidence circuit 15, Fig. 2 (not shown), to cancel out the early gate pulse when this overlaps the transmitted pulse. Circuit 15 then feeds no output to unit 19 and a weak echo appearing from out of the larger transmitted pulse can push the late gate pulse in front of it to a point where the early gate pulse is once more unsuppressed and normal operation resumed.

Abstract: At least one layer of foamed synthetic organic plastic material and at least one layer of a substrate material are bonded together by using an adhesive which, prior to curing, comprises a solution of urethane prepolymer having terminal isocyanate groups blocked with at least one blocking agent comprising an imine, oxime or ketoxime.  The blocked prepolymer has a mol. weight of 400/6,000, and an NCO: blocking agent ratio of from 1 to 2, and contains a sufficient quantity of a curing agent having reactive hydrogen terminals to provide an NCO:  active hydrogen ratio of from 0.5 to 2. The adhesive compound preferably contains up to 5 parts by weight of a cure accelerator and 50 parts by weight of a filler per 100 parts by weight of unblocked prepolymer.  The adhesive is applied to one or more of the surfaces to be contacted and the coated surfaces are lightly pressed together to produce a partial penetration and a temporary adherence of the layers.  The adhering layers are then heat-treated at 175/400 DEG F. to unblock and heat cure the prepolymer and effect a permanent bond.  The initial tackiness of the adhesive may be varied by using partially blocked and partially cured prepolymers or by adding fillers such as silica.  The urethane prepolymers may be derived from esters or ethers, esters being preferred, particularly those prepared from ethylene/glycol/propylene glycol/ adipic acid mixtures or castor oil. Diisocyanates usable are toluene diisocyanate, dyphenyl diisocyanate, 1, 5-naphthalene diisocyanate and hexamethylene diisocyanate.  Blocking agents usable include ethylene imine, propylene imine, acetophenone oxime, butyraldoxime, methyl methyl ketoxime, cyclohexanone oxime and methyl ethyl ketoxime, the last being preferred.
