Title: Coating apparatus
IPC: H01J9/26
Filed: 1958-04-14
Abstract: <PICT:0844102/III/1> An apparatus for applying a coating of solder glass frit to the mating surface of a television picture tube panel or funnel, comprises a bed having a vertical passage therethrough, a rotatable annular support arranged about the passage for holding a panel or funnel with its mating surface facing upwards, means for rotating the support, a container for frit having a bottom passage, means for moving the container to a position in which its outlet is in vertical register with a crosssection of the said mating surface, and for maintaining such relationship while the support is being rotated to present the entire mating surface progressively to frit issuing from the outlet, and means for continuously stirring the frit within the container.  As shown, a support 15 for the panel 18 is supported on rollers 16 and confined laterally by rollers 17, and is arranged to be rotated by a friction drive roller 20, driven by a motor 21, which is slidably mounted on rods 24, and may be moved to engage or disengage the drive by a pneumatic cylinder 26.  A carriage 30 is slidably mounted on rods 31, 32, and supports a tank 35, for the frit, and a motor 43 for driving an agitator therein.  The tank 35 has a bottom orifice controlled by a pneumatically-operated needle valve, and a slight positive pressure is maintained in the tank to aid in the extrusion of the coating-material, which may be a suspension of ground thermal setting sealing glass in a nitrocellulose solution.  To maintain the tank orifice over the portion of the article to be coated, a rotatable roller 52 is mounted stub shaft on a disc fitted in the inner race of a ball-bearing, mounted on the tank, and the platform 30 is lightly urged by a pneumatic cylinder 55 to maintain the roller continuously in engagement with the side wall of the panel. Pneumatic and electrical circuits, for controlling the operation of the machine, are described.

Title: Blow out preventors for wells
IPC: E21B33/06
Filed: 1923-05-02
Abstract: 215,562. Kelly, T. J. May 2, 1923. Bore-hole apparatus; wells. -- A blow-out preventer for wells comprises a housing anchored in position around the drill pipe and means operable by excessive gas pressure and controlling segments or collars for preventing ejection of the pipe. The housing H is longitudinally divided and is held assembled on the well casing W by bolts through paclied flanges 17 and by sleeves 23. 24 threaded on to tapered end portions 25, 26 of the housing. Rods R brace the structure. Within a conical chamber 19 in the housing, conical slips 27, 28 are slidably held by dovetailed guides 31; the slips have serrations 29 and pack. ings 30 and rest on a ring 32 carried by plungers 33. When excessive gas pressure occurs, the gas acts on ring 32, serrations 29 and packing rings 30 and lifts the slips into position to grip the drill pipe D; the gas &c. then passes from the chamber 19 through pipes 25b to storage. When high pressures are anticipated during drilling, the slips may be lifted into gripping position beforehand by admitting air, steam &c. through pipes 36, 35 to act on the plungers 33.

Title: Improvements in and relating to the preparation of tungsten and molybdenum carbides
IPC: C01B32/949
Filed: 1951-05-23
Abstract: Tungsten or molybdenum carbides of particle size of 1/2 to 10 microns are prepared by introducing finely divided (100 to 500 micron) particles of the corresponding metal carbonyl into a pyrolysis zone heated to 650-1000 DEG C.  In order to obtain a purified carbide, the pyrolysis products may be heated in a controlled carbon dioxide carbon monoxide atmosphere of 800-1850 DEG C. in the case of tungsten carbide (WC), the relative concentrations of the two gases being adjusted in accordance with the equilibrium constants at a particular temperature to avoid free carbon and tungsten oxide formation and to further production of the carbide.  Treatment at 650 to 800 DEG C. favours the formation of W2C and the corresponding molybdenum carbides may be prepared under the same conditions.

Title: Improvements in or relating to cathode ray oscillograph arrangements
IPC: H04N5/74
Filed: 1934-04-23
Abstract: 416,834. Television receivers. COSSOR Ltd., A. C., Highbury Grove, London. -(Assignees of Ardenne, M. von; 19, Jungfernstieg, Lichterfelde-Ost, Berlin.) April 23, 1934, No. 12192. Convention date, April 21, 1933. [Class 40 (iii).] In a cathode-ray oscillograph arrangement the picture produced on the fluorescent screen is projected on to a viewing screen by means of a lens system comprising a large main lens of simple condenser glass and a small lens constructed so that an enlarged picture is produced without appreciable distortion. The small lens which is placed nearer the fluorescent screen is corrected for spherical aberration. The correction of the smaller lens for chromatic aberration may be avoided if the spectral range of the light for projection is limited to the band between red and yellow-green, by using a fluorescent material with a mainly yellow response, e.g. zinc sulphide, or by using a filter for blue light in the path of the light rays. Alternatively, the glass of the small lens or of the end of the oscillograph tube may be coloured to act as a filter for blue light, or the projection screen may be coloured with chrome yellow eliminating the blue part of the spectrum so that the chromatic error is reduced to a negligible amount.

Abstract: 880,538. Tension regulating winding. ATLAS WERKE A.G. April 7, 1960, No. 12438/60. Class 78 (5). The invention relates to a steam-warping or towing winch 3, 2 provided with an automatic device 8, 9, 10 for hauling in cable to resume the original position after the cable has been pair out in consequence of an increased tractive force. According to the invention, an automatically-operating steam pressure regulator 13 is connected to the steam supply pipe 11 between the boiler (not shown) and the steam engine 3; and an overflow regulator 15, set to a slightly higher pressure than the steampressure regulator pressure, is connected to the pipe 11 between the engine 3 and the regulator 13. Steam can thus flow off from the engine through the overflow regulator 15 when the winch is turning in the reverse direction. The device 8, 9 10 comprises a slide valve 10 set by a travelling nut 9 on a spindle 8 geared to the drum 1 of the winch. The automatic device 8, 9, 10 may be by-passed by suitably setting isolating valves 17, 18, 19 and 20.

Abstract: 217,891. Western Electric Co., Ltd., (Assignees of Demarest, C. S., and Almquist, M. L.). June 21, 1923, [Convention date]. Calling systems. - In a radio communication system the central station carrier current is modulated by low frequency impulses according to a definite code in order to call the secondary stations individually. The latter are each provided with means selectively operated by the impulses. The Figure shows the central station A connected through the hybrid coil 3 to a line 2 and having transmitting and receiving antennae 16, 17. A selector key 10 which may be of the type described in Specification 117,170 controls a relay 7 which is adapted to connect a source of low frequency current 8 to an amplifier 14 the output of which serves to modulate the output of the transmitter 15. One of the secondary reactions is shown at B and comprises a receiver 22 and transmitter 52. The receiver 22 is connected either to a telephone 26 or through a transformer 28 to a relay 31 adapted to be operated by the low fre. quency impulses and the circuit of which is made resonant to the low frequency current. The vibrating armature 32 of the relay 31 is adapted to cause relav 34 to maintain its armature 39 attracted while the signalling low frequency current is maintained, thus connecting a source of potential 38 to a selectively operated circuit closing device 40 which is preferably of the type described in the above-mentioned Specification. The closure of the contacts 46, 47 of the selector device 40 energizes a relay 48 and operates a signal device 50 on receipt of the predetermined code of impulses each of which causes the relay 34 to operate. In a modification of the receiving apparatus at the secondary station the received waves are detected and a plug and jack arrangement provided to allow the insertion of an amplifier before the signals operate the relay 31. In this modification an additional relay having two armatures each provided with two contacts serves to reverse the current to the selective device on receipt of a signal and a holding circuit is provided for the signal device which is released on the operation of a kay which renders the receiver 26 operative. A slow-acting relay may be employed in addition to the selector 40 for alternative use.
