Abstract: 437,911. Brake drums. BUGATTI, E., Molsheim, Bas-Rhin, France. Oct. 3, 1934, No. 28312. Convention date, Oct. 12, 1933. [Class 103 (i)] In brake drums for internal shoes, particularly such having cast iron linings, ventilating passages are provided within the rim which lead from a point on a lateral face of the rim to another point on the opposite lateral face or on the external periphery, said other point being at a greater distance from the drum axis than the first point so that air is caused to circulate by centrifugal force in a unilateral flow from the first point to the second point. According to Figs. 1 and 2, the lining 3 attached as by bolts 5 to the outer member 1 secured to the disc 2 of a wheel has a number of annular chambers 6 connected by transverse passages 7 or slots 9 and communicating with apertures 8 in the member 1. The apertures 8 may be disposed close together or further apart and they may be radially inclined as shown respectively in Fig. 2, A, B, C. The chambers 6 may be dispensed with. Under the action of centrifugal force, air enters the passages 7 or 9 and escapes through the apertures 8. The passages 7, 9 may be inclined to the drum axis so that the centrifugal action is supplemented by the effect of inertia of the air. The lining may also be provided with holes or slots running from one lateral face to the other and inclined to the drum axis in such a way that air enters at one face and leaves at the other under the action of centrifugal force. The outer member 1 may be slotted axially so as to grip the lining elastically or it may be in separate segments. The member 1 and the outer surface of the lining may be conical.

Title: Preparation of concentrated solutions of alkylchlorphenoxyacetates
IPC: C07C51/41
Filed: 1951-12-10
Abstract: Solutions containing 15 per cent. to 40 per cent. by weight of alkali metal or ammonium salts of alkylchlorophenoxyacetic acids such as 2-methyl-4-chloro- or 2-methyl-6-chloro-phenoxyacetic acid are prepared by forming the insoluble alkaline earth metal salts of the alkylphenoxyacetic acid, separating the water soluble impurities and converting to the alkali metal or ammonium salts by double decomposition with an alkali metal or ammonium hydroxide or carbonate.  The alkaline earth salts of the alkylchlorophenoxy acetic acid may be prepared preferably by condensing an alkylchlorophenol with monochloroacetic acid in the presence of an alkaline earth hydroxide or alternatively by reacting an alkali metal salt of an alkylchlorophenoxyacetic acid with an alkaline earth chloride. Excess of alkali metal or ammonium hydroxide or carbonate in the final concentrated solution may be treated with carbon dioxide to lower the pH.  In examples (1) and (2) a mixture of crude monochlorocresols comprising mainly the 2-methyl-4-chlorophenol is condensed with monochloroacetic acid in the presence of slaked lime and the resulting calcium methyl-chlorophenoxyacetates are converted to the sodium salts by double decomposition with sodium carbonate, and (3) a solution of sodium methylchloro-phenoxyacetates is treated with calcium chloride and the resultant calcium salts are converted to sodium salts by treatment with aqueous sodium carbonate. Specification 702,623 is referred to.ALSO:Solutions containing 15 per cent to 40 per cent by weight of alkali metal or ammonium salts of alkylchlorophenoxyacetic acids, prepared by first forming the insoluble alkaline earth metal salts of the acids, separating the water soluble impurities and converting to the alkali metal or ammonium salts by double decomposition with an alkali metal or ammonium hydroxide or carbonate (see Group IV(b)) are used as selective weedkillers.

Title: Improvements in or relating to coupling circuits for coupling between a waveguide and a transmission line
IPC: H01P5/08
Filed: 1953-10-21
Abstract: 745,701. Wave-guide transformer circuits. CULLEN, A. L., ROGAL, B., and WAYNE KERR LABORATORIES, Ltd. Oct. 21, 1954 [Oct. 21, 1953], No. 29122/53. Class 40 (8). A coupling between a wave-guide 51 and a transmission line, e.g. a coaxial line 50 or another wave-guide, of different frequency-dependent characteristic impedances comprises a length of further wave-guide 52 which forms E-plane T-junctions with the transmission line and wave-guide to be coupled. The Specification discusses the best dimensions of the coupling guide for a broad-band characteristic and it is shown that the cut-off frequency fc of the coupling guide should be such that where # 1  and # 2  are the cut-off frequencies of two wave-guides to be coupled and fm is the midband frequency. If one of the wave-guides is replaced by a coaxial line the formula is modified by putting f 1  =0. Where the coupling guide is broader than the guides to be coupled its physical dimensions may be reduced by providing it with a ridge or loading it with a dielectric. The length of the coupling waveguide is normally one quarter of the mid-band wavelength. If very weak coupling is desired and a sufficiently low characteristic impedance unobtainable by mere choice of dimensions an inductive diaphragm 53 may be used at one end of the coupling guide and a capacitive diaphragm 54 at the other. The frequency variation of susceptance of the diaphragms may be set off one against the other or against the frequency variation of the characteristic impedance of the wave-guides. In this case it may be preferable to use a coupling guide of length different from a quarter guide wavelength.
