Abstract: 1433236 Cathode-ray tubes INST YADERNOI FIZ SIBIR OTDELENIA AKAD NAUK SSSR 22 Aug 1973 39710/73 Heading H1D A microwave amplifier or frequency multiplier includes, in sequence along the beam path, a particle beam source, on accelerating tube 4 for imparting relativistic energies to the beam, and a deflection system 5 for sweeping the beam, at an input signal frequency, in a conical path such that it passes through circular entry and exit slits in the side walls 10 of an annular resonator to an annular collector 13, the resonator being provided with means for extracting microwave power. As described, the assembly 4 includes an electron gun and a rectifier-fed multi-electrode accelerating tube (2, Fig. 1, not shown). The deflection system is formed by two pairs of deflection plates fed in quadrature from the signal source 7, and the resonator may be shaped as shown to produce normal incidence of the beam on the resonator; alternatively, the resonator may be planar, and normal incidence of the beam produced either by a pair of part-spherical annular electrodes (Fig. 2, not shown), or by a magnetic lens. The annular electromagnet 14 compensates for the effect of the induced radio-frequency magnetic field, and outwardly directed flanges around the two edges of the resonator entry and exit slits constitute cut-off waveguides to reduce the escape of radiation. When used as an amplifier, when the resonator is arranged such that the circular beam path therearound is equal to an input signal wavelength #, the output is derived from at least two identical non-directional couplers spaced apart by #/4 around the resonator (Fig. 5a, not shown). For frequency multiplication, the beam path is arranged to be an integral number of input signal wavelengths, and two or more identical non-directional couplers are spaced apart by a sub-multiple of the wavelength (Figs. 5b to 5e, not shown).

Title: Preparation of condensed isopropyl silicate materials
Inventor: EMBLEM HAROLD GARTON
IPC: C08G77/02
Filed: 1959-03-18
Abstract: A condensed isopropyl silicate is made by adding gradually to SiCl4 a mixture of water and isopropyl alcohol, the amount of water added being from 0.75 to 1 mol per mol of SiCl4 and the amount of alcohol added being in excess of that stoichiometrically required to replace those chlorine atoms of the SiCl4 with which the water is insufficient to react, refluxing the mixture and removing excess alcohol by distillation. In examples (1) a mixture of anhydrous isopropyl alcohol and water was gradually added to SiCl4 and the resulting mixture was refluxed for 1 hour and left overnight, unreacted alcohol was then removed by distillation up to 100 DEG C., leaving a crude product having a SiO2 content of 38.05%; further distillation up to 200 DEG C. removed the orthosilicate content, leaving a mixture of isopropyl polysilicates having a SiO2 content of 38.5%; (2) the process was similar to (1) except that the reflux time was increased to 4 hours, resulting in products having SiO2 contents of 39.5% and 40.7% respectively.  Uses: for binding refractory powders in the preparation of moulds for the casting of metals, as described in Specification 948,132.

Abstract: 858,410. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 22, 1958 [Dec. 27, 1957], No. 41355/58. Class 100(4) A printing apparatus has a plurality of type faces on a flexible endless band continuously moving past a plurality of print hammers which are individually actuated when the type required at that point on the record sheet is opposite the particular hammer positioned at the same point. As shown in Fig. 1 an endless chain belt 10 having spaced type members 13 passes over rollers 11, 12 which are continuously driven, and in front of an inked ribbon 31 and a record strip 17 behind which are print hammers 27. The record strip 17 is advanced intermittently by sprocket wheels 20, 21 coupled together by a belt 22 and the hammers 27 are operated individually by' electromagnets 30. In a simple digital printer the data is stored in a magnetic drum 34, Fig. 2, which rotates once as the belt 10 is advanced one type space, the hammers being more closely spaced to allow for the time required for the drum 34 to advance one scanning position. As shown eleven hammers occupy the space of ten type members. A timing track 35a is read by an inductor means 36a which passes signals to a print location distributer 37 and a chain character distributer 41. The former is an eleven stage binary counter which passes a pulse in turn to each of one of amplifiers 381 to 3811 corresponding to print hammer operating magnets 301 to 30<SP>11</SP> while the latter is a ten stage counter, each stage representing the character which is opposite a hammer, passing signals to a conventional comparator 40. When the comparator receives an equal signal from one of the storage reading inductor means 36b to 36e and the chain character distributer 41 it provides an output to all the amplifiers 381 to 3811 and that amplifier at that moment also receiving the output of the print location distributer 37 will actuate the corresponding magnet 30 to operate the appropriate hammer 271 to 2711 to print the desired character in the desired position. A modified storage and operating arrangement capable of printing any of 48 characters is also described.

In a mine roof support assembly having a series of mine roof supports each of which, Fig. 1, comprises support props 1, an advancing jack 2 and a main control valve assembly 3, 4 operable when a pilot line 11 connected thereto is pressurized to cause the support to undergo an advancing operation, each support has a pilot valve assembly 5, Fig. 2, manually operable to cause pressurization of the pilot line 11 of the adjacent preceding support or adjacent subsequent support in the series. Each pilot valve assembly 5 comprises two pilot valves 16, 17 normally open to connect lines 12, 14 to a return line 9, 7. Each pilot valve assembly has a lever 19 pivotable in one or other direction to operate one or other of its valves 16, 17. Operation of the valve 16 on one pilot valve assembly causes pressurization of its line 12 and hence pressurization of the pilot line 11 of the adjacent left hand support. Similarly operation of the valve 17 on that assembly causes pressurization of the pilot line 11 of the adjacent right hand support. Pressurization of the pilot line 11 of a support, Fig. 1, opens prop release valves 21 and fluid flows from the props through a line 22, a valve 23 and a line 25 into the return line 7. At the same time pressure in the line 11 actuates a valve 26 which results in pressurization of a line 27 to cause the jack 2 to advance by pulling the support up to an anchorage such as a conveyer (not shown). When the support is fully advanced a valve 28 is opened by the jack 2 to cause pressurization of a line 29. The pressurization of the line 29 actuates the valve 23 to cause the line 22 to be pressurized and hence re-set the props against the roof. A valve 32 operable to cause the jack to advance the conveyer is operated by pressurizing a line 33.
