Title: Improvements in or relating to reflectors for microwave antennae
IPC: A23C1/03
Filed: 1956-08-14
Abstract: 795,428. Radio reflectors. ALBISWERK ZURICH AKT.-GES. Aug. 14, 1956 [Oct. 18, 1955], No. 24848/56. Class 40 (7). The invention relates to arrangements for facilitating the construction of rigid parallel strip radio reflectors, particularly reflectors for energy having a wavelength of less than 15 cm. According to the invention such a reflector is constructed of metal strips which are evenly spaced in planes parallel to each other and to the reflector axis and the strips are connected to braces lying in planes perpendicular to the said parallel planes and to a frame by links each having two mutually perpendicular pivotal axes. The strips are separated by spacers and the links joining the strips to the braces can advantageously be made alike. In one embodiment a paraboloidal reflector is formed from a plurality of edge on strips 1 supported by links from perpendicular rear braces 2 which, together with the ends of the strips are attached to a circular frame 3. As shown in Figs. 4 and 5, the links 5 connecting the strips with the frame and the links 4 connecting them with the braces are each provided with mutually perpendicular eyes. The frame and braces are U-shaped and bolts 7, 6 pass through the sides of the U in a direction transverse to the length of the member and through the eye in one end of the links. The strips 1 are of narrow U-section and are retained on the other ends of the links 4, 5 by bolts 8. The same bolts 8 also secure spacers 10 arranged along one side of each strip which butt against the next adjacent strip but are not fixed thereto. Preferably rubber buffers 11 are provided on the contact ends of the spacers to damp mechanical vibrations. Angle pieces 9 serve to hold the braces 2 to the ring 3 and are attached by rivets.

Title: Process for the production of high-molecular weight, linear organo silicon dioxy, arylene polymers
IPC: C08G77/00
Filed: 1961-07-10
Abstract: In making linear organosilicon-dioxy-arylene polymers having a molecular weight of at least 10,000 and the general formula:- <FORM:0932326/IV(a)/1> wherein A1 and A2 are arylene radicals, R1 and R2 are alkyl or aryl radicals and n is an integer, polymers of this type are heated and the macrocyclic compounds of the general formula: <FORM:0932326/IV(a)/2> thus formed are simultaneously distilled off from the reaction mixture under reduced pressure and reheated at atmospheric pressure, thus again forming, by fission of the ring, high molecular weight linear organosilicon-dioxy-arylene polymers. The heating is preferably effected in the presence of a transesterification catalyst.  Chain interrupters, e.g. 2-ethylhexanol, hexane-1,6-diol, trimethylol-ethane, -propane and -butane, phenol, ethyl- and t-butyl-phenols and phenoxytrimethyl- and diphenoxydimethyl-silanes, solubilizers, dyestuffs, pigments, fillers and biologically-active substances, may also be added.  In a typical example (1) 2,2-(4,41-dihydroxy-diphenyl)-propane, the sodium salt thereof and diphenoxy-dimethyl-silane were slowly heated in a flask from 150 DEG  to 300 DEG C.; after removal of unreacted phenol the viscous residue was heated to 340 DEG -360 DEG C. under reduced pressure and the reaction product remaining in the flask was then distilled off to yield a cyclic organosilicon compound which was mixed with zinc stearate and heated to 300 DEG C. in an atmosphere of nitrogen to yield the desired polymer.  Uses: The intermediate products may be used as plasticizers and modifying agents for polyesters and polyamides; the linear polymers can be used as adhesives, cements and binding agents, as well as castings and/or mouldings.  German Specification 1,082,057 describes the preparation of the linear polymers by reacting aromatic dihydroxy compounds with equivalent amounts of dihalo- or dialkoxy- or diaryloxy-dialkyl- and/or diaryl-silanes.

Abstract: 906,939. Automatic gain control arrangements. HAZELTINE CORPORATION. July 22, 1959 [Aug. 27, 1958], No. 25140/59. Classes 40 (5) and 40 (6). In a transistorized radio receiver the gain is varied by variation of the degree of negative feed-back in an R.F. stage 43 (Fig. 3). The emitter circuit of transistor 43 comprises a resistor 45 shunted by the variable emitter circuit impedance of a second transistor 51, the base voltage of which comprises a variable A.G.C. bias derived from detector 29. The two transistors may be of opposite conductivity type (Fig. 4, not shown) so that the unavoidable change in current through the transistor 43 is such as to increase the A.G.C. effect. A tuned circuit may also be placed in series with the emitter circuit resistor (Fig. 5, not shown) so as to tune out the effect of the emitter-collector capacity of the second transistor. In a modification, the emitter path of the transistor 43, Fig. 7, comprises the collector circuit of transistor 51, the impedance of which is reduced by negative feed-back over condenser 81 and resistor 83 to the base; the effective impedance is again varied by variation of the base bias. The Specification also describes the equivalent valve circuits (Figs. 2, 6, not shown). Reference has been directed by the Comptroller to Specification 807,815.

Filed: 1929-08-19
Abstract: 335,024. Groves, W. W., (I. G. Farbenindustrie Akt.-Ges.). Aug. 19, 1929. Diaphragms.-A sound-box membrane is made from a cellulose derivative and consists of a circular film diminishing in thickness towards the periphery and comprising a system of closely adjacent hollow chambers. The cellulose derivative, such as waste film, is dissolved in a mixture of solvents, of which one component boils at a considerably lower temperature than the rest, so that on evaporation of this component, hollow chambers are produced while the mass is still viscous. In an example 4 grams of a solution of 20 per cent waste nitro-cellulose film in a mixtureof 3 parts of ether and 1 part of ethanol are poured on a glass plate. When drying begins, the surface of the mass arches in the form of a section of a sphere, and the honeycomb of chambers is formed.

A hydrostatic bearing comprises a bearing element 2, 3 supporting a member 1, pressure chambers 4, 5 on opposite sides of the bearing being supplied with fluid via restrictors 11, 12 comprising gaps between opposite annular walls 9, 10 of a housing 6 and a diaphragm 8. Fluid'is supplied from lines 15, 16, 17, to annular ducts 13, 14 and passes through restrictors 11, 12 and chambers 9a, 10a to respective chambers 4, 5. On loading of part 1 the pressure in chamber 5 and thus in restrictor 12 increases while that in chamber 4 and restriction 11 decreases. The diaphragm 8 is thus deflected, and the rate of flow to chamber 5 increased. Hence width of the bearing gaps does not vary with the load. In Fig. 3 (not shown), pressure chambers are formed in a supported member.
