IPC: B22F3/11
Filed: 1968-06-07
Abstract: 1,173,709. Powder metallurgy: Al base alloy bearings. CHRYSLER CORP. June 7, 1968 [June 7, 1967], No. 27288/68. Headings C7A and C7D. A sintered porous metal such as Al, Al alloys, Cu or bronze is made by compacting a powder mixture of the metal with a fatty acid having at least 12 C atoms and a wax having a melting point not exceeding 150 C., removing the fatty acid and wax from the compact by heating to a maximum temperature of 345 C. in an evacuated chamber in which an inert gas such as N 2 , A or He sweeps away the volatilized acid and wax, and then sintering. The mixture contains 0À2-2% fatty acids and 0À1-1% wax, the metal powder being minus 35 mesh Tyler and preferably 200 to 325 mesh. Suitable fatty acids containing 12-22 C atoms are:- lauric, palmitic, margaric, tridecansic, stearic, oleic, brassidic, arachidic, linoleic, behenic, erucic, linolenic, elaidic, elesstearic, lichemic, ricinoleic, palmitoleic, petroselenic. The suitable waxes are the ester reaction products of fatty acids containing 12-34 C atoms and compounds containing at least one active hydrogen atom e.g. alcohols, amines, amides. Examples of these waxes are carnaulia wax, beeswax and spermaceti. Sintered Al bearings containing Zn, Cu, Mn, Sn, P6, Mg and Si may be formed by compacting at 2-10 T/#", dewaxing at below 3, 500 microns e.g. 50-200 microns in a steam of inert gas and then sintering at above 500 C. followed by oil impregnation and coining. Several examples of different Al alloys are given in the range 2-5% Cu, 1-6% Sn, 0-4% P6, 0-1À5% Mg remainder A1.

[Class 40 (v)] A circuit for deriving a voltage for muting a receiver during atmospherics &c. comprises two signal rectifiers with opposed outputs and different time-constants, or a single rectifier giving two outputs of differing characteristics. In one embodiment, Fig. 1, the signal across resistance 2 is fed to a diode rectifier circuit 6, 7, 8 of long time-constant and a fraction, preferably half, of the same signal voltage is fed from the tapping 9 to the diode circuit 3, 4, 5 of short time-constant. There is thus produced between the control points a, b connected to the diode anodes a voltage which changes in sign when, due to a disturbance, the peak voltage from the system 3, 4, 5 exceeds the smoothed voltage from system 6, 7, 8. This voltage may be used to disable an amplifying stage or detector or to close a signal path by rendering conducting a diode shunted thereacross or non-conducting a diode in series therewith. The latter arrangement is shown in Fig. 7, in which the control points a, bare connected to the grids 52, 53, respectively, of a double triode d.c. amplifier valve 50, the anodes of which are connected through a load resistance 57 the terminals c, d of which feed the signal component thereacross to the output terminals 41, 42 through a diode 34.

Patent GB-456855-A (GB)
Title: Improvements in and relating to transparent films of rubber hydrochloride
IPC: C08C19/12
Filed: 1935-10-11
Abstract: Films of high transparency are obtained by spreading a solution of rubber hydrochloride on a surface, evaporating solvent from the exposed surface of the film material, and then smoothing out irregularities in the surface of the resulting film while it contains not more than 15 per cent of solvent.  The smoothing treatment may be carried out before or after the film is removed from the forming surface.  Smoothing may be effected by passing the film into pressure contact with a highly polished heated surface, such as a pressure roll.  A steel roll may be caused to contact with the <PICT:0456855/IV/1> surface of the film from which solvent has been evaporated and the film may be supported by a rubber covered roll, a hard rubber roll, or other resilient surface.  In an example, a solution of a partially saturated rubber hydrochloride dissolved in benzene is spread out as a thin film on an endless smooth belt so as to produce a continuous film.  The greater part of the solvent is evaporated with the aid of a forced draught and the film containing 5--15 per cent of solvent is then passed between highly polished heated pressure rolls which may be engraved so as to impress or emboss a figure or design on the film.  As shown, rubber hydrochloride solution is fed through pipe 3 on to the endless belt 1 provided with a hood 2 to carry off solvent vapour.  The thickness of film is regulated by a spreader 4.  The film 5 is stripped from the belt and passed through pressure rolls 6, 7 where irregularities in the surface are smoothed out.  The film then passes through a festoon drier 8.  Specification 437,304, [Group V], is referred to  The Specification as open to inspection under Sect. 91 describes also the application of the process to the manufacture of films from other materials including other rubber derivatives such as halogenated rubber.  This subject-matter does not appear in the Specification as accepted.
