Title: Improvements in or relating to coupling devices for coupling a coaxial transmission line to an electrical device
Inventor: GARDINER MAURICE
IPC: H01P5/04
Filed: 1957-09-24
Abstract: 849,490. Impedance matching. GENERAL ELECTRIC CO. Ltd. Dec. 23, 1958 [Sept. 24, 1957], No. 30007/57. Class 40(8). [Also in Group XL(c)] Coupling between a coaxial transmission line and an electrical device which may, for example be a second coaxial line, is varied by movement of a member of insulating material which bears against a probe connected to the end of the inner conductor of the line and lies in a space in the electrical device. The invention is described in connection with a valve amplifier in which one coaxial line forms the output connection and another length at coaxial line forms the anode circuit. The amplifier comprises a triode valve 1 the grid-cathode circuit of which is formed by a non-resonant length of ridged waveguide 2 formed by a recessed lower member 4 and an upper member 5 secured together by screws 6. A metal part 8 connected to the grid electrode of the valve is screwed into the member 5 to provide for grounded-grid operation, a metal part 9 connected to the cathode being spaced from the member 4 by an insulating sleeve 10. An input coaxial line 11: has a probe 12 projecting into the waveguide 2 opposite an adjustable screw 15 which in conjunction with a further adjustable screw 18 enables the coupling to be varied and matching achieved over a range of frequencies in the region of 200 mc/s./sec. The anode circuit is formed by a resonant quarter-wave section of coaxial line 3 loaded by a metal ring 21. Connection to the anode is effected through a rod 24 and a metal member 27 insulated from a metal member 26 by a layer of mica 25 and provided with fingers 30 engaging an anode disc 28. Metal fingers 23 extending from the rod 24 engage an anode cap 22 for cooling purposes. The outer conductor 32 (Fig. 2) of an output coaxial line 31 is integral with or connected to the member 5, and the inner conductor 33 carries a probe 34 of resilient material such as phosphor bronze or beryllium copper projecting into the resonant line 3. Coupling is adjustable by rotating a screw 35 of insulating material such as polytetrafluorethylene which bears against the probe 34, and tuning is effected by metal screws 36 and 37. The coaxial lines 11 and 31 may be terminated by coaxial sockets.

Title: Method and apparatus for machining a plurality of work-pieces in identical manner
IPC: G05B19/421
Filed: 1953-10-30
Abstract: 766,547. Drilling. LINDNER GES., H. Oct. 30, 1953 [Nov. 11, 1952], No. 30059/53. Class 83 (3). [Also in Group XL (b)] A method for the repeated positioning of a machine-tool table 8 consists in aligning an edge of the work 11 with a tool, such as a drill 4, making a mark on a reference gauge 17, making further marks according to the machine operations to be performed, and setting subsequent workpieces according to the marks on the gauge. In a coordinate drilling-machine, adjustable gauge-bars 12, 17, Figs. 1 and 9, and marking devices 15, 18 are associated with each slide 7, 8 of a compoundtable. A control-box 19 contains push-buttons 21 for starting and stopping movements of the slides, means 20 for viewing the adjustment of each slide according to a coarse or fine scale, and a hand wheel 22 for fine adjustment of each slide. The device 18 comprises a diamondtool 28 which can be pushed downwardly to mark the surface of the gauge 17. The mark is projected on to a screen 42, Fig. 2. The shadow of the mark falling on a photocell 46 can be used to control the movements of the slide 8. The setting-gauges may be formed as round or polygonal bars, Fig. 4, having a number of sets of markings which can be indexed into position. Alternatively, the markings may be formed in rows on a flat bar which can be adjusted transversely to its length. Instead of indexing the bars, the transmitting apparatus may be moved. In operation, a workpiece is secured to the table and reference squares 68, Fig. 9, are placed on each edge of the workpiece. The slides are then moved successively to align marks on the squares with a microscope 66, Fig. 8, positioned on the tool spindle 3. At each aligned position a mark is scratched on the gauges to indicate the zero reference points. When the zero marks have been made, the remaining coordinate settings are marked on the gauges. After the work has been drilled and removed, the edges of a subsequent workpiece are aligned to the zero reference marks. The gauges may be in the form of magnetic-wire records 75, Fig. 10, with marking and gauging devices 78, 79; in a modification, a magnetic-impulse is used to signal the approach of a scratch-mark made on the wire. Alternatively, a decreasing signal 87, Fig. 14, may be given to denote the approach of a scratch marking 85 and to slow down the slide movement gradually. When a pre-signal is being used, the fast motion may be switched off and the final slide movement effected slowly under automatic photo-cell control or by hand.

A safety razor comprises a guard member including spaced, parallel front and rear guards and a backing member parallely spaced between the guards and joined to both ends of at least one of them, a blade supporting member hinged at one edge to one edge of the guard member which it overlies to clamp the blade, and bladeejecting lugs extending outwardly from the hinged end of the guard member to intercept the blade as the blade supporting member is swung open. As shown, a razor head for a single-edged blade is set obliquely on a handle 19 and comprises a rear guard 2 integral with a backing member 3, the junction being depressed to form a cleaning trough, a front guard 1 joined to the backing member by spacers 5, 6 to provide a cleaning slot 7, and a blade-support 8 having blade positioning lugs 12, 13 and an offset end portion 9 which is hingedly mounted on a pin 10 the blade being flexed when the curved blade-clamping members are locked together by a resilient clip 11. Blade ejectors 18 intercept an edge of the blade when the blade support is swung open. In a modification the offset end portion 9 is of reduced width and is adjustable along the pin 10 to position the blade relatively to the toothed guard I the blade support 8 having an inwardly curved guide portion which adjusts the position of the blade support so that both ejector lugs are effective. The amount of opening of the blade support may be limited by abutment means such as a leaf spring welded to the inner surface of the blade support 8 and abutting the blade ejectors. When not in use the blade is reversed between the clamping members so that the cutting edge is towards the rear guard and is protected. In further modifications the backing member is integral with the front guard, or is secured to both guards by two spacers. In a form suitable for use with double-edged blades the razor head is at right angles to the handle and both guards are serrated. Suitable single-edged blades are provided by breaking double edged blade 32, Fig. 13, along score lines 37. The razor handle has an imbedded magnet 22 for retrieving blades.

Title: Improved process for the production of methane and methane mixtures from carbon monoxide and hydrogen
Inventor: WENDLANDT RUDOLF
IPC: C07C1/06
Filed: 1951-12-28
Abstract: A cyclic process for the production of methane comprises catalytically converting a gas mixture containing substantially less than 3, e.g. 1.1-1.5 parts of H2 per 1 part CO to methane, mixing the reaction mixture thus formed with fresh synthesis gas in a volume at least equal, e.g. 2-6 times, that of the fresh gas, and feeding the combined mixture to the catalyst at about 200-300 DEG C.  The fresh gas may be preheated with the unreturned reaction mixture and then mixed with the returned gas which is still at above 100 DEG C. to give a temperature of 200-300 DEG C. Heat from the entire reaction mixture may first be used for steam generation or the like.  CO2 may be separated from the reaction mixture or from the returned portion thereof before or after admixture with the fresh gas, in particular by drying agents containing potassium carbonate at 90-130 DEG C. in the presence of water.  In this way water may be removed from the reaction mixture as well as CO2.  In an example, fresh gas containing H2 and CO in the ratio 1.37:1 is mixed with 2.62 times its volume of recycle gas at 330 DEG C. to give a temperature of 260 DEG C. at which the combined gas is fed to a Ni-Mn-Al catalyst, ratio 10:2:1. The exit gas at 410-430 DEG C. passes to a steam boiler to cool it to 340 DEG C.  The part not recycled is cooled to separate water, and CO2 removed.
