Title: Improvements in weight checking and sorting apparatus
IPC: B07C5/20
Filed: 1925-11-04
Abstract: 265,293. Jahn, A. R. Nov. 4, 1925. Sorting by weighing.- A weight-checking and sorting machine comprises a distributing platform disposed between two weighing-plates. an oscillating arm for pushing parcels on to each plate alternately, and a shoot contiguous to each weighing-plate at the side opposite to the distributing platform whereby after each weighing operation the parcel is removed from the plate to the shoot by the next oncoming parcel. Parcels are fed down a shoot A, Fig. 1, on to a platform D from which they are pushed transversely on to the weighing-plates 10 of two balances B, C by means of an oscillating arm 3 actuated by a cam 8. The balances are of similar construction and each comprise a beam 15, Fig. 4, and parallelmotion links 16, 17. The weighing-plate of each balance is locked in equilibrium position during loading by means of a table 20 and pawl 26, Fig. 6, the table being pressed into engagement with the underside of the weighing-plate and the pawl engaging a pin 29 on the link 16. The locking- mechanisms are actuated by cams 30. Mounted on each weighing-plate is a hinged flap 12 having a slot 13. A plunger 35, Fig. 4, reciprocated by a cam 36 is adapted to pass through the slot 13 when the balance is in equilibrium. Thus a parcel of correct weight remains on the weighing- plate until pushed down a shoot E by the next oncoming parcel, but if a parcel is too light or too heavy the plunger misses the slot and engages the flap, causing it to push the parcel down a shoot H. In a modification, the flap has two slots arranged on the same level and co-operating with a plunger which terminates in a fork, one arm of the fork having an undercut bevel and the other an overcut bevel.

Abstract: 602,767. Valves. LACY-HULBERT & CO., Ltd., and ROBINSON, V. S. Oct. 22, 1945, No. 27775. [Class 135] [Also in Groups XXVIII, XXXII and XXXV] An unloading valve 2 connected to the delivery pipe 1 of an air compressor system (see Group XXVIII) comprises a hollow piston 3 urged to its open position by the rod 11 of a spring-urged dashpot piston 12 against a spring 7, and is closed when the compressor is started by compressed air gaining access through a vent 6 to the upper side of the piston to pile up pressure thereon. The rate of closing of the valve is dependent on the setting of a regulating valve 17 controlling the oil flow between the upper and lower sides of the piston 12. Member 19 is an oil filler.

Title: Improvements in or relating to powder metallurgical techniques
IPC: B22F3/105
Filed: 1963-07-12
Abstract: A powder mixture of Al with up to 8% by weight of Mg, Sn, Zn or Cu and a binder such as sterotex, "NOPCOWAX" (Registered Trade Mark) or a hydrogenerated vegetable oil is shaped and sintered in a furnace maintained at 560  DEG -1300  DEG C. the time in the heating zone being less than 30 minutes so that a liquid eutectic phase is formed but melting of the Al does not occur.  The sintering is preferably effected by passing the compact on a continuous belt through a H.F. field for 5-60 seconds and the furnace atmosphere may be H2 even with a dew point higher than -80  DEG F., N2 Co, natural gas or air. Alternatively a two stage sintering process may be used, the first stage involving presintering for 3/4 -1\ba1/3 minutes in a furnace maintained at 560  DEG -1300  DEG C. and the second stage at 590  DEG -650  DEG C. for 3/4 -20 minutes. When sintering in air the powder compact is preferably dipped in a light mineral oil or paraffin containing 70-80% of a powder Al brazing flux prior to sintering. The sintered compact may be quenched in water or, when used as a bearing, in an oil which impregnates the compact.  Various types and sizes of Al powder may be used such as He or air atomized powder, shot, needles and flakes varying from 40 mesh to minus 325 mesh.

Filed: 1921-10-21
Abstract: 189,617. Electric Construction Co., Ltd., and Close, F. W. Oct. 21, 1921. Electrically-tripped switches. - To increase the current value at which tripping occurs, for instance in starting electric motors, the solenoid plunger C is pressed on by a braking device to prevent it from rising. A slider F having a knob f moves in a guide G against the action of a spring f<2>. It carries a second spring f<1> at its inner end which frictionally engages the plunger C when the knob f is pressed in. A pin f<3> and the closing-up of the spring f<2> limit the travel. In this way, a much larger current is required to raise the plunger.
