Title: Improvements in or relating to domestic washing machines.
IPC: D06F17/00
Filed: 1967-01-12
Abstract: 1,160,331. Washing-machines. CALOR APPAREILS ELECTRO-DOMESTIQUES. 12 Jan., 1967 [24 Jan., 1966], No. 1686/67. Heading D1A. A machine for washing clothes comprises an impeller 3 mounted at the bottom of the tub and driven by a motor 11 mounted above the tub. The impeller is mounted on a removable plate 5 and driven from drive shaft 8 by an engaging pinion 7 or friction wheel. The top of shaft 8 is releasably coupled to the motor drive shaft 10. The motor casing 12 can thereby be removed and inverted to close the tub again with the motor housed substantially within the tub. The top closure is completed by a lid 28 having tongues engaging the casing 12, and which lies above the shaft 8 when the motor is housed. The liner may be separated from the impeller by a removable grid.

Abstract: 1,098,842. Coupling microwave signals in phase to a common load. GENERAL ELECTRIC CO. Ltd. Jan. 14, 1966 [Jan. 14, 1965], No.1695/65. Heading H3A. In an arrangement for connecting two equal frequency microwave transmitters 1 to a common aerial load 2, means are provided for ensuring that the signals combine in the load in the same phase. Each transmitter includes a frequency changer to which a modulated intermediate frequency signal from source 8 is applied directly and a microwave signal from source 5 is applied via a phase-shifting device and the output of the frequency changer is applied via a pair of travelling wave amplifiers to the input branches 12, 13 of a hybrid waveguide coupler 14. Branch 15 of the coupler is connected to aerial 2 and branch 16 to a resistor 17 and the arrangement is such that if the signals applied to the coupler are 90 degrees out of phase both signals combine in phase at the aerial and no energy is dissipated in the resistor. Branches 15 and 16 include further couplers 18, 19 whereby a small amount of the energy flowing in the branches is applied to two input arms 21, 22 of a Magic T junction 20 and voltages which are a function of the vector sum and difference of these signals is developed in detectors 24 connected to the co-linear arms 23. A comparison between these signals is obtained in unit 25 which supplies an output to control the phase-shifting devices connecting the source 5 to the transmitter frequency changers. The circuit is arranged such that when no power is being supplied to the resistance 17 the control output from unit 25 is zero.

Title: An improved method and apparatus for the continuous descaling of hot rolled, strip-form ferrous products
IPC: B08B1/02

Abstract: 806,055. Cleaning metal strip. THOMAS, E. Jan. 18, 1956 [Jan. 26, 1955, May 18, 19551. No. 1782/56. Class 82(2) Scale is removed from the lower side of hot-rolled ferrous metal strip by passing it, between brake rollers 3 at the extreme end and driven rollers 26 at the exit end which tension the strip, over guide rollers 6-9 and a guide bar 11 which are staggered vertically to form a zig-zag path of which the angle X formed at bar 11 may be varied by vertical adjustment of the bar. The strip also passes over further rollers 17-21, and powerdriven brushes 14, 22 and 23 remove the scale, which is crushed between the strip and guide bar 11. Fig. 3 shows the crosssectional shape, and the method of mounting, of the bar 11. The upper part of the bar is cylindrical, with a radius of curvature about five times the strip thickness, and merges into vertical side walls so that a tapering crevice between it an and the lower surface of the strip causes crushing of the scale to a slip-promoting medium. The upper surface of the strip may be descaled by apparatus similar to that of Fig. 1 except that the arrangement of guide rollers, guide bar and brushes, above and below the strip, is reversed. If desired, more than one guide bar may be used, the angles formed in the strip by them progressively decreasing; preferably these angles lie between 70 and 110 degrees.

Abstract: 1,139,241. Continuous chlorination of polyvinyl chloride. PRODUITS CHIMIQUES PECHINEY - SAINT - GOBAIN. 17 Jan., 1966 [15 Jan., 1965; 16 Dec., 1965], No. 2118/66. Heading C3P. Polyvinyl chloride is chlorinated continuously by a process wherein a reaction chamber(s) is fed with particles of polyvinyl chloride and with a current of chlorine gas-alone or mixed with an inert gas-in the presence of radiation so that the polyvinyl chloride is maintained in a fluidized state by the chlorine or chlorine-containing gas, and the chlorinated polyvinyl chloride is continuously drawn off, the operational velocity of the current of chlorine being above the velocity critical for opacification of the surfaces transparent to radiation. Desirably, a series of chambers is used and the chlorinecontaining gas runs countercurrent to the polyvinyl chloride, thereby causing the reaction to take place by stages.

Abstract: Fat-splitting agents are obtained by sulphonating aliphatic carboxylic acids containing at least twelve carbon atoms in the molecule or their derivatives, in the presence of aliphatic oxysulphonic acids, sulphuric esters or salts thereof, carbyl sulphate or mixtures of the same.  Hydrocarbons which condense with the fatty acids, e.g. xylene, toluene, naphthalene or hydrogenated products thereof may be added prior to the sulphonation, and further to facilitate the latter the substances used in the processes of Specifications 293,690 and 312,283, [both in Class 2 (iii), Dyes &c.], may be added.  The fatty acids may be partially sulphonated before the introduction of the oxysulphonic acids &c., and they may also be converted into their anhydrides or chlorides before sulphonation.  In examples: (1) castor oil is treated with sulphuric acid in the presence of isethionic acid; (2) the fatty acids of castor oil are treated with fuming sulphuric acid in the presence of 2-methylbutanol-sulphonic acid (Schwartz); (3) linseed oil is treated with sulphuric acid in the presence of 1-propanol-3-sulphonic acid.

Abstract: 942,230. Pilot controlled automatic volume control. FELTEN & GUILLEAUME FERNMELDEANLAGEN G.m.b.H. Jan. 24, 1962 [Jan. 24, 1961], No. 2576/62. Heading H4R. In a pilot controlled automatic volume control system in which the pilot signal is transmitted in a gap in the signal frequency spectrum, the signal frequency spectrum is monitored before addition of the pilot and if any signal frequency is present in the pilot signal gap the pilot signal is disabled. The intermediate amplifier regulator system has a threshold so that the absence of the pilot signal disables the gain regulator. Alternatively, or additionally, the presence of energy in the pilot signal gap causes the insertion of a band stop filter tuned to the pilot frequency. The presence of such a filter permanently is undesirable in view of its poor transient response. The Figure shows the preferred embodiment in which the pilot signal from generator c is normally added to the signal frequency from input b in a coupling circuit 3, the presence of energy at the pilot frequency in the signal frequency input at a is detected by the filter 1a and amplifier 1b and operates relay 1c to open contacts 6 and prevent the addition of the pilot signal to the transmission. At the receiver the pilot channel comprising filter 5a and amplifier 5b includes a relay device 5c which responds only to signals above a predetermined threshold to operate a gain regulating device 4a. In a modification components at the pilot frequency in the transmitter signal frequency input, that are of such a level as to be above the operating threshold of the gainregulating device in the intermediate amplifier cause the opening of contacts 7 shunting a filter 2 tuned to the pilot frequency to eliminate these components from the transmitter output.
