Abstract: 972,133. Fluid-pressure brakes. H. TEVES. E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND ARMATURENFABRIK KOMM.-GES.]. July 14, 1961, No. 25605/61. Heading F2F. An automatic braking regulator for motor vehicles consists of a housing 1 with a stepped piston 2, the larger step 3 of which possesses a valve port 32 to transfer the pressure medium from the master cylinder to the front wheel cylinder via ports 6, 19, 7 so that the full face and annular face of the large step 3 are impinged upon by the master cylinder pressure and the wheel cylinder pressure respectively and its small step 4 is subjected to the pressure of a resilient means, i.e. the pneumatic suspension, which also is initially transmitted in the opening sense to the valve body 16. The pneumatic suspension works against concentric floating pistons 10, 12, pressure being transmitted through the former to the small step 4 and through the latter via a slidably mounted rod 14 to valve 5. The pressure of fluid to the wheel cylinder increases until the thrust on valve 5 balances the thrust of the pneumatic system whence valve 5 closes. As the master cylinder pressure further increases the pressure in the wheel cylinder is boosted. In a second embodiment (Fig. 2) the large step 34 is limitedly, slidably mounted in the housing 33 about a valve which has secured to it the smaller step 35. A single floating piston 51, resiliently mounted on spring 52, transmits the suspension pressure to the small step. The operation of the valve is as described above.

Title: Improvements in or relating to the production of organic compounds containing oxygen
IPC: C07C51/12
Filed: 1929-08-22
Abstract: Acetic acid; methyl acetate.-In the production of oxygenated organic compounds, particularly acetic acid and other carboxylic acids and esters thereof, by the action of carbon monoxide on alcohols either in the free or combined state in the presence of inorganic acid catalysts of the type defined in Specification 283,989, [Class 2 (iii), Dyes &c.], promoters comprising vanadium, chromium, manganese, iron, nickel, cobalt, or compounds of these metals, or mixtures thereof with one another or with copper or copper compounds are incorporated in the catalysts.  The process is particularly applicable to the production of acetic acid and methyl acetate by the action of carbon monoxide on methyl alcohol or compounds capable of decomposing under the conditions of the reaction with the separation of a methoxy group or methyl alcohol. Such compounds include dimethyl ether or methyl esters such as methyl formate or acetate.  When methyl formate is employed carbon monoxide is formed by its decomposition, and in this case the addition of further carbon monoxide, although preferable, may be dispensed with.  The proportion of methyl acetate in the product depends on the relative proportions of methyl alcohol, carbon monoxide, and water vapour present in the starting materials.  The reaction is preferably carried out at temperatures between 250 DEG  and 400 DEG  C., and pressure up to 300 atmospheres or more may be employed.  Inert gases may be present. The main catalyst may consist of any of the phosphoric acids or a mixture thereof, acid phosphates, or aromatic sulphonic acids.  The phosphoric acid may be employed in the liquid form or on an inert solid carrier.  The promoter is preferably a compound of iron or manganese, for example, the hydroxide, acetate, or formate of either metal.  The apparatus in contact with phosphoric acids may be lined with gold, platinum, or graphite, or made of or lined with copper. According to an example a vapour mixture of methyl alcohol, water, and carbon monoxide obtained by passing carbon monoxide through liquid methyl alcohol at 50-56 DEG  C. and afterwards through water at 80 DEG  C. is passed at 120-160 atmospheres pressure over a catalyst consisting of pyrophosphoric acid with 0,5-1,0 per cent of iron or manganese formate maintained at 290-315 DEG  C. in a gold-lined reaction vessel.  The products are separated by condensation, the condensate containing methyl acetate and acetic acid, and the uncondensed gases are returned to the reaction. Hydrocarbon and other undesired products may be removed from the circulating gases by means of absorbents such as active carbon, absorbent charcoal, or silica gel.  Specification 317,867, [Class 2 (iii), Dyes &c.], also is referred to.

Abstract: 1,224,246. Aerials; radio navigation. SINTEF. 30 May, 1968 [8 June, 1967], No. 25890/68. Headings H4A and H4D. An I. L. S. localizer aerial system comprises a plurality of dipole arrays. In each array all or most of the dipoles have lengths and spacings which conform with those of a log-periodic array. As described, an aerial system comprises six separate aerial arrays 1 to 6, Fig. 1. Each array consists of dipoles arranged in general with lengths and spacings according to a logperiodic law. However, in order to enhance backward radiation from the system, the length and spacing of at least one dipole of an array is deviated from the exact log-periodic relationship. The system is arranged at one end of an airfield runway to provide azimuthal guidance for an instrument landing system. The arrays are spaced symmetrically about the centre line S of the runway, with their axes parallel thereto. The same modifications may be made to all the arrays, when their backward radiation lobes 1a to 6a will be the same. The back course sector width may be increased by modifying the arrays 1, 2, 5, 6 differently from the arrays 3, 4 so that the backward radiation lobes 1b, 2b, 5b, 6b are smaller than the lobes 3a, 4a. An arrangement is described in which a feedline for a dipole array comprises two metal tubes which support the dipole arms and which are spaced apart by dielectric material and are enclosed in a coating of dielectric material (Fig 3, not shown). In addition to providing means for controlling backward radiation, the system is also intended to reduce course line aberrations due to unwanted reflections &c.

Abstract: 1,092,147. Semi-conductor amplifiers. RADIO CORPORATION OF AMERICA. June 18, 1965 [July 10, 1964], No. 25972/65. Heading H3T. In a frequency-selective amplifier the input power is shared equally between a plurality of semi-conductor devices by providing a reactance in series with the input to each device and a common impedance to resonate with the reactances at the operating frequency; selfoscillation in any one device cannot then result in excessive power dissipation in the others. Fig. 4 shows a two-stage UHF power amplifier in which the second stage comprises three parallel transistors 170, 171, 172, each with an input inductor 146, 147, 148 which resonates with a capacitor 141. The collectors are joined together by a low-inductance plate 149 having cut-away portions 200, 201 to minimize capacitive coupling with the input connector 145. The output circuit 150-156 and input circuit 121-127 each comprise capacitance-coupled double-tuned circuits, and an extra tuned circuit 133, 140 is similarly provided between the two stages. The inductors 146, 147, 148 have a high impedance relative to the input impedances of the transistors so that the latter may be unequal without producing unbalance in the drive. A VHF version with two emitter-biased transistors and single-tuned circuits is also described (Fig. 3, not shown).
