Filed: 1939-02-18
Abstract: 525,470. Automatic exchange systems. RYALL, L. E. Feb. 18, 1939, No. 5466. [Class 40 (iv)] [Also in Group XL] The gain of an amplifier 10 feeding voice frequency signals from a telephone line &c. to relays 26, 28 is controlled by a non-linear resistance 19. The valve 10 is normally on the threshold of oscillation due to a feed-back from a-bridge circuit constituted by a centre-tapped secondary of a transformer 16, an ordinary resistance 18 and the resistance 19 which may be a 6 volt 40 ma. metal filament lamp glowing dull red. The feed-back is applied to a grid transformer 15. The oscillation frequency is about 340 c.p.s. The incoming signals from transformer 13, amplified by the valve 10, are taken from the upper secondary of transformer 16 and are of substantially constant amplitude as a slight increase of current through the lamp 19 causes the feed-back to change from positive to negative. The time-constant of the lamp 19 is longer than the oscillation time so harmonic distortion is not introduced. The signal output from transformer 16 is further amplified by a valve 20 having negative feedback and is applied through transformer 21 to circuits associated with the grids of valves 25, 27 controlling the relays 26, 28. The upper circuit is tuned to 750 c.p.s.. whilst the middle one is tuned to 600 c.p.s. The lower is a guard circuit and contains rejectors 29, 30 tuned to the signal frequencies of 600 and 750 c.p.s. and is operative upon the reception of voice currents to apply a negative bias to the valves 25, 27.

Filed: 1931-02-23
Abstract: <PICT:0375366/III/1> <PICT:0375366/III/2> <PICT:0375366/III/3> <PICT:0375366/III/4> In making heel base units for boots and shoes, a rand strip is coated on one side with adhesive and is applied to a heel lift which has been coated over the area covered by the rand strip. Rubber latex or other adhesive which acts after drying when the parts are pressed together is used.  In applying adhesive to a heel lift, the lift is pressed between two rotating conical rolls 22, 24, Fig. 2, the lower one of which dips into a tank 62 of adhesive, and is carried by a spring-mounted arm so as to be capable of slight vertical movement.  The rollers serve to hold the edge of the lift against a gauge 80 during its travel between the rollers despite the varying curvature of the edge, by the outer portion 23 of the upper roller being spring-mounted so as to be driven only frictionally by the inner portion 22.  An uncoated portion s, Fig. 7, may be left near the edge of the lift by providing the lower roller 24 with a groove 90 which is kept clear of adhesive by a scraper.  In a similar machine for applying adhesive to rand strips, the upper roll 122, Fig. 10, is mounted upon the shaft 120 by a universal joint 123. Adhesive may be supplied to the tank on the bird-fountain principle from an inverted bottle fitted with a closure containing a valve which is opened by a projection on it contacting with the bottom of the tank.  A knife 252 may be mounted so as to trim off the inner edge of the strip during its passage between the rollers.  The coating-apparatus described with reference to Figs. 9 to 20 of Specification 302,958, [Class 95, Paints &c.], may be modified by providing below the applying roller, a conical feed-roller mounted on a vertical shaft, and by providing a pivoted finger which engages the breast of the heel lift so as to eject the lift before the breast is coated.  For pressing together the adhesive-coated lifts and rands, the parts are passed together between rotary conical rolls 322, 324, Fig. 27, the lower one of which is yieldable against a spring, and are pressed against a gauge 360. The lower roll may have inclined grooves cut in its surface tangential to the edge of the central recess, and crossed by concentric grooves.  Alternatively, the parts may be pressed together on a stationary table by a reciprocating pressing head which carries means for trimming off the projecting ends of the rand and also operates an ejector for discharging the work after the pressing.

Abstract: 551,147. Iron alloys; annealing. GENERAL MOTORS CORPORATION. April 30, 1942, No. 5801. Convention date, May 1, 1941. [Classes 72 and 82 (i)] [Also in Group XXII] Steel powder is made by simultaneously breaking up and embrittling molten iron containing 0.8 per cent. or more of carbon, by quenching in water and comminuting and annealing the particles so formed. Iron and steel scrap may be melted, carbon being added to obtain the desired percentage, and atomized in water. The brittle particles so formed are then crushed in a ball mill &c. and then annealed above 1200‹F. This powder may be moulded at 60 to 160 thousand pounds per sq. inch and sintered in a non-oxidizing atmosphere at 1900‹ F. to 2100‹ F. to form porous articles which may be hardened by any known process. If desired graphite may be added before moulding for lubricating purposes and the article may be packed in a material which will prevent decarburizatiion during sintering. Up to 5 per cent. of manganese, nickel, vanadium, chromium, cobalt, or other alloying ingredient may also be added before moulding. Finally the article may be hot pressed to increase its density to 95 per cent. of that of conventional steel.
