Title: Improvements in and relating to ultra high frequency attenuator
IPC: H01P1/22
Filed: 1949-12-14
Abstract: 666,760. High - frequency attenuators. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 14, 1949 [Dec. 24, 1948], No. 32111/49. Class 40 (viii). An attenuator for high-frequency systems comprises a wave-guide section 1 having a closed end through which is sealed an input coaxial line 4 having an input plate 2 connected to its internal conductor 3 and an output plate 6 is mounted on the inner 7 of an output line 8 secured in a sliding plug 9 which closes the open end of the wave-guide section. The perimeters of plates 2 and 6 extend close enough to the inner surface of the guide to capacitatively couple them thereto and reduce the distortion of the fields as energy is transferred. This reduces the distortion of the logarithmic characteristic the attenuator would possess in the absence of end effects.

Title: Brush
IPC: A46B5/00
Filed: 1946-10-30
Abstract: 626,334. Brush cases. MULVILLE, F. N. B. Oct. 30, 1946, No. 32257. [Class 18] [Also in Group XXIII] A brush comprises a brush head, a casing formed in two portions pivoted together and defining between them a space to house the bristles of the brush, the brush head being hinged or pivoted to one of the portions of the casing, spring means associated with the brush head for urging said brush head towards its operative position in which it lies outward of said casing and said brush head being capable of being swung from its operative position against the action of the spring when the casing is open into a position where the bristles are housed within the casing when the latter is closed and spring means for urging said two portions together said spring, such means being strong enough to prevent the two portions being separated by the spring acting on the brush. head when the latter is housed within the casing, the pivot between the two portions of the casing being located along a line adjacent to the back ends of the two portions so that on squeezing the back ends together the front of the casing opens up in the manner of jaws. In the Figures, the casing which may be of thin sheet steel is in two portions and the brush head consists of a wooden member 6 to which the bristles are secured and which is pivoted on a pin 7 between the side walls of the lower portion. A coil spring 8 (Fig. 3) closely surrounds the pin 7 and is attached at one end to side wall 3 and at the other end to the wooden member 6 and tends to rotate the brush into operative position (Fig. 2) in which the back curved portion 9 abuts rim 5 thus preventing further rotation. A spring 14 between the two portions is provided just in front of the pivot pin 13 by which the two portions are pivoted and tends to keep the casing closed. In order to enclose the brush the front of the casing is opened by squeezing the back ends together and the brush moved inwards so that the bristles lie within the lower portion of the casing whereupon the top portion of the casing is allowed to close. The brush is opened by squeezing the back ends of the portions together when the front opens and the brush head swings into its operative position, the top portion is then allowed to close and the brush head is thus held against rotation since the curved portion 9 abuts the small rims 5 and 12 at the front of the two portions of the casing which thus serves as a handle for the brush.

Title: Process for the production of high btu methane containing gas
IPC: C01B3/50
Filed: 1975-08-04
Abstract: 1467219 Methane production D L BANQUY 4 Aug 1975 [13 Aug 1974] 32474/75 Heading C5E A process for the production of a high Btu methane rich gas from a carbonaceous or hydrocarbonaceous feedstock comprises (a) generating a gaseous effluent having a substantial CO content from the feedstock and purifying it to remove impurities such as residual carbon and sulphur compounds, (b) dividing the resulting gaseous effluent into a plurality of fractions, (c) subjecting a first fraction to methanation, (d) subjecting a second fraction to shift conversion followed by CO 2  removal, (e) mixing the resulting effluents from steps (c) and (d) and methanating the mixture, and (f) separating any excess nitrogen present from the product. The feedstock may be fossil fuels such as coal, waste polymeric materials, shale oil, naphtha or heavier hydrocarbon feedstocks or gas oil, and the gasification is performed in the presence of either oxygen enriched air or pure oxygen. Either a catalytic or non-catalytic process may be employed, and if the former the catalyst bed may be fixed or fluidized. The purification of the gaseous effluent uses conventional scrubbing methods with NaOH, KOH or diethylamine, the solvent being regenerated and recycled. The methanation of the first purified fraction is performed with recycling of part of the products, and steam may be mixed with the feed gas to the methanation so as to achieve shift conversion of part of the CO content of the gas. The shift conversion of the second fraction is preceded by humidification of the feed gas to ensure a sufficient amount of steam for the conversion. A combination of both high and low temperature conversion stages may be involved. The gaseous product is cooled before being subjected to CO 2  removal by scrubbing with a solvent such as an amine compound, K 2 CO 3 , methanol. The combined products from the first methanation and shift conversion stages are subjected to a two stage methanation involving a first high temperature reaction and a second lower temperature reaction, products being recycled from the lower temperature reactor to the higher temperature reactor. After drying, the products from this methanation are subjected to cryogenic separation to remove nitrogen.

Title: Improvements in vacuum brake cylinders
IPC: B60T13/46
Filed: 1920-11-20
Abstract: 155,242. Hardy, Geb. Dec. 10, 1919, [Convention date]. Fluid-pressure.-Relates to vacuum brake cylinders in which the rolling ring between the piston and cylinder functions in the manner of the usual non-return valve, which is dispensed with. The space for the rolling ring 1 in the release position of the piston 3 is formed by conical surfaces 2, 4 on the piston and cylinder, the generatrix of the surface 2 being at a greater angle to the base thereof than that of the surface 4 so that the space increases in width towards the base of the cylinder whereby air can flow past the ring from the upper to the lower chamber of the cylinder; but the ring is seated by an increase of pressure in the lower chamber. The ring is under a slight initial tension so that it tends to seat. A wire ring 6 with vertical parts 7, resting on a step formed on the cylinder, prevents the ring 1 from being forced into the annular space between the piston and the lower part of the cylinder. The initial position of the cylinder can be adjusted by screws or other adjustable abutments 8 to cause the ring 1 to seat effectively as it slackens with use. The ring can be placed in position by detaching the lower part 5 of the cylinder.

Filed: 1952-12-29
Abstract: 724,166. Electric tests. COLLINS RADIO CO. Dec. 29, 1952 [March 13, 1952], No. 32875/52. Class 37. [Also in Group XXII] A jig for holding an electromechanical filter comprising a disc with a wire attached to its periphery as disclosed in Specification 722,664, [Group XL (b)], has a measuring position in which the resonance frequency is measured electrically, and a second position, in which a selected length may be cut from the end wire to adjust the resonance frequency. As shown, the disc 39 with its end wire 41, Fig. 4, is first held loosely resting against a cover disc 42 within a cylindrical aperture in an arm 23. The arm is then slid upwards along a guide shaft 14, Figs. 1 and 2. A guide pin 21 on an upper fixed plate 12 first engages a guide hole 24 in the arm 23 and subsequently a pin 26 on the arm engages a hole 52 in a spring detent 27 to lock the arm in the measuring position in which the wire 41 extends through a hole 17 in the plate 12 into the resonance frequency measuring device 16. The frequency having been measured, the detent 27 is released and the arm 23 withdrawn. A thumb screw 31 is then tightened to hold the disc firmly in the arm 23 which is then rocked about the shaft 14 to the position in which the guide hole 24 in arm 23 is aligned with a second guide pin 22. The arm 23 is then again moved upwardly along shaft 14 guided by the pin 22, to the cutting position in which the wire 41 extends the desired amount through a hole 19 in the plate 12. The amount of the wire projecting through the plate 12 and cut off by the pivoted cutter 53 is determined by the setting of a micrometer 33 which adjusts a pin 38 axially in an arm 32 which is slid upwards along the shaft 14 to a limit position determined by a thumb screw 34 secured to the arm and movable in a slot 37 in a fixed upright plate 36. The pin 38 engages a pin 28 secured to arm 23 and pushes the arm 23 before it into the cutting position. By successive measuring and cutting operations as above described the resonant frequency is increased to the desired value. Resonant frequency, measuring, Fig. 5. The end wire 41 extends through two coils 44, 46. The coil 44 is energized from a signal generator 43 and by virtue of the magnetostrictive action of the wire 41 energy is imparted to the coil 46 which is amplified at 47 and its magnitude indicated on a voltmeter 48. The frequency of the source 43 is then adjusted to the resonance frequency which is indicated by a maximum reading on the voltmeter.

Abstract: 1328714 Rotary conveyers; reciprocating conveyers DAINI SEIKOSHA KK 13 July 1971 [14 July 1970] 32893/71 Heading B8A [Also in Division G3] Parts used in the manufacture of, for example, watch movements, are supported by externally grooved frames (10, Fig. 3, not shown) stacked in compartments 13 of containers 3 which are slidably mounted on horizontal guide rails 2, 2a over a rotary table 5. To move a container 13 along the guide rails a shaft (80, Fig. 11, not shown) is rotated, via a lever (41), by a cam 40 so that a gripper (81, Fig. 9, not shown), fixedly mounted to the shaft (80), engages an axle 22 on the container. Shifting of the container then results from intermittent rotation of a cam 91 on a shaft 92 releasing a spring-biased lever (85, Fig. 12, not shown) connected to the shaft (80) which then moves horizontally. Rotation of the wheel 5 is effected by rotation of a shaft 27 which is intermittently driven by a wheel 100 on a shaft 26 and which is connected to table 4, 5 via gears (102-105, Fig. 14, not shown). In use a first set of parts is delivered from a first compartment 13 to recesses 6 on the table 5 and after assembly or machining of the parts has been effected they are returned to the compartment simultaneously with a second set of parts being delivered to the recesses from a second compartment. The process may then be repeated. Delivery of the parts to the table 5 is effected by rotation of a shutter ring (19, Fig. 6, not shown) to align projections 15b, 15c thereon with the grooves on the frame (10). Rotation of the shutter ring (19) is effected thus: a cam 30 fixed to shaft 26 turns a lever (31) which engages a pin (34) which rotates an actuating plate 23 about tis axle 22, a groove on the plate engaging a pin (21) on the shutter ring. In the return to a compartment 13 a part is lifted by a thrust rod (120, Fig. 15, not shown) which is driven, via a lever 121 and a rod 122, by a cam 60 on shaft 26.
