Abstract: A process of making a sintered metal article containing more than 50% weight of a metal such as Al, Mg, Ti, Be, Zn or Pb whose oxide is not reduced by hydrogen at the melting point of the metal comprises compacting the powder mixture containing 0 to 5% lubricants at 0 to 30 t.s.i. to a maximum density of 98% theoretical and sintering in an atmosphere having a dew point of -60 DEG F. to -20 DEG F. at a heating rate of at least 20 DEG C. per minute. The Al used may be a powder, needles, wire strips or turnings and may vary in size from 3 microns to 1/2 inch.  Up to 45% weight of alloying powder additions such as Al, Mg, Si, Zn, Cu may be added to the base metal.  The Cu may be added as powder or flake.  For the production of porous parts the compacting pressure is 0-5 t.s.i. and 5-30 t.s.i. for dense parts.  Sintering is effected at above the eutectic or peritectic temperature or above the melting temperature of the lowest melting constituent.  If only one metal is present the sintering temperature is 50 DEG C. below the melting temperature.  The sintering atmosphere may be H2, N2 or the inert gases and may be carried out continuously on a sintering belt type furnace. The sintered article may be coined, forged, rolled, extruded or bent and heat treated e.g. solution treated and aged.  The rate of heating during sintering may range from 20 DEG  to 600 DEG C. per minute.

Abstract: 1,182,285. Extensible supporting arms; collapsible walking sticks. C. C. OLSON. 25 May, 1967, No. 24341/67. Headings A4H and A4P. [Also in Division E1] An extensible arm, tent pole, or walking stick is formed by a continuous steel or brass strip 22, wound in overlapping layers and stressed outwardly to provide frictional engagement between the layers. The arm is extended by pulling the inner and outer layers in opposite axial directions the arm and, remains in extended position by virtue of the resilience of the strip. The strip is enclosed in an outer tube 25 to which the outer end 24 of the strip is pivotally secured by means of a slit disc 26 and a slot 28. The inner end of the strip is secured to an inner tube 30 by means of a loosely staked tubular rivet 31. The inner tube is secured to a handle 35 and the outer tube has a pin 42 adapted to lock the tube to a hook 44 on a wall mounting assembly. The extent of the extension of the arm is determined by a wire or spring 36 secured at one end to a partition 38 in the outer tube 25 and at the other end to the inner tube 30. The arm may comprise two coiled strips disposed in end to end arrangement within and secured to a single outer tube (61 Fig. 6). The arm is extended by pulling the inner ends of the coils in opposite directions. Stiff wire handles 81, 82 and bumper caps (85, 86) are provided on the inner ends of the coils. The two coils may be wound in the same or opposite directions. In the embodiment shown in Fig. 10 the layers have sloping portions 95 and ledges 94 and, when extended, the end of the sloping portion 95 of one layer presses against the ledge 94 of the underlying layer. The longitudinal load thrust on a walking stick or tent pole is transferred from the coil to the outer tube 102 by a split ring 109 and a locking nut 110 threaded on the tube 102. Threading the nut on to the tube forces the split ring to engage between the end 111 of the tube and a ledge 94 of a coil. A rod (105) is slidably mounted in the inner tube (98) and has a tapered portion (107) which can be pushed into engagement with the coil ends (108) to cause them to engage fully. The coiled strip may comprise five strips (116, 116a, 117, 117a, 117b, Fig. 12) welded together at their ends and the two uppermost layers 116, 116a form a slot 119 in which ball bearings are placed. The outer and inner ends of the coiled strip may be secured by means of holes to a spring (124, Figs. 13, 14) secured to a circular piece 127 through which a rod 128 slides. The rod is pulled to extend the coiled strip, an end 130 of the rod engaging the spring.

Abstract: 317,299. Cinephone Co. Soc. Anon. Aug. 11, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Multiple machines ; combined working of gramophones with kinematographs.-A gramophone is provided with two turntables which are adapted to be driven alternately from a main shaft, clutch mechanism being automatically operated in such a manner that at predetermined intervals one turntable is stopped and the other one started. In the arrangment shown in Fig. 2, a continuously rotating shaft 19 carries two clutches 4, 5 and 4<1>, 5<1>, the parts 5, 5<1> which are loose on the shaft being geared to the turntable spindles 1, 1<1> respectively, through wheels 6, 6<1>. The clutch members 4, 4<1> splined to the shaft 19 are connected by a forked bar 8. This is adapted to be reciprocated by an eccentric 9, .carried by a Maltese cross 10, which is itself actuated by a cam connected to a crank on the spindle of a pinion 13 engaged by a spring-controlled rack 14. The end of the rack is held in engagement with a cam disc 15, slowly driven by the main shaft 19, steps (or the equivalent) on the cam being provided at intervals corresponding to the duration of playing of a soundrecord. With this arrangement, at the end of each record the bar 8 is shifted lengthwise, so as to interrupt the drive of the turntable carrying the played record and bring the other turntable into operation. In a modification, clutches are provided on the turntable spindles, instead of on the main shaft, and are actuated by levers controlled by a horizontally arranged cam disc concentric with a Maltese cross. The single cam 15 may be replaced by the multiple cam shown in Fig. 9. This comprises differently formed cams 15<1>, 15<11>, 15<111> mounted on a spindle which is vertically adjustable, so that any one cam may be selected to operate the mechanism. Further, a worm shaft formed with steps along the edge of the worm may be provided instead of the disc cam 15, the worm shaft being traversed axially as it rotates. Mechanism is also decribed whereby the change-over from one turntable to another is effected when a predetermined number of pictures on a kinematograph film has been projected. Such mechanism comprises a spring- pressed rack, the longitudinal movements of which are controlled both by a notched disc slowly driven by the projector through a worm shaft, and by a detent lever engaging a toothed disc fixed on the worm shaft. In order to cut out noises due to needle-scratch, during the period between the starting of a turntable and the commencement of sound-reproduction, the movement of the rack effecting the clutching-in of the turntable may cause the circuit of the electric soundreproducer to be broken, the circuit being reestablished after a predetermined period has elapsed.
