Title: Improvements in or relating to apparatus for the manufacture of powdered materials
IPC: B22F9/22
Filed: 1953-09-10
Abstract: <PICT:0749265/III/1> An apparatus for the manufacture of a powdered material by the reaction of a gas with another powdered material in which one or more of the powders produced is magnetizable includes means for producing a magnetic field in the reaction chamber whereby magnetic material entrained in the exhaust gas stream is removed therefrom.  As shown, applied to the reduction of iron oxide by hydrogen, a conical glass or stainless steel vessel 1, having its apex downwards, is charged through a side tube 8 with ferric oxide and a gentle stream of hydrogen is passed through the inlet 6 at the apex of the vessel.  As the ferric oxide is reduced to ferrosoferric oxide the stream of hydrogen is increased and any magnetic material in the gas stream is collected at a narrower neck 2 in the vessel on opposite sides of which are pole pieces 5, 51, of opposite polarity, of electrically energized magnetic cores 3, 31, and the clean gas passes out through an outlet 7.  As the amount of magnetic material increases in the neck 2, the electric supply to the magnet may be cut off at intervals for a short time, say 1-2 seconds, and at the same time the flow of hydrogen may, if desire, be reduced.  Any non-magnetic material, particularly if finely divided, mixed with magnetic material will also be collected by agglomeration of the particles.

Title: Improvements in envelope machines
IPC: B31B19/00
Filed: 1924-10-29
Abstract: 236,509. Smithe Machine Co., Inc., F. L., (Assignees of Novick, A.). July 3, 1924, [Convention date]. Envelopes, making.-Relates to a machine for folding the sealing-flaps of envelopes after the drying operation, and for counting the completed envelopes. Partially-completed envelopes 15, Fig. 1, are delivered from the drying-belt 16 be- .tween faster moving bands 30, 31, Fig. 6, so that the envelopes are separated, and are brought to rest against stops 44, when a ball 47 holds them stationary. Feelers 23 are raised by each blank in its passage along the belts 30, 31, so that the shaft 50 supporting the feelers is rocked to operate an escapement controlling a transfer mechanism. A member 59, Fig. 11, on the shaft 50 has two teeth, the upper one 63 of which holds an arm 60 until the movement of the feelers 23 turns the member 59, allowing the arm 60 to drop on to the tooth 64. An eccentric 61 on a shaft 62 is prevented from rotating by the ,arm 60 until the feelers 23 are freed and release the tooth 64. The eccentric is frictionally driven, and its sheave 86 is connected to an arm 88 on a shaft 89. A downwardly-depending arm 76 on the shaft 89 is connected to slide-bars 66 carrying the transfer blades 67, which push the envelope resting against the stops 44 between belts 94, 95. The envelope is passed beneath a guide-plate 99, and the projecting sealing-flap 18<a> is folded by a bar 43 on to the body of the envelope, a roller 101 creasing the flap. Brushes 127 deliver the envelopes on to a slowly-moving belt 129, where they overlap. Each twenty-fifth envelope is displaced by a feeler 143 mounted on an arm 142, Fig. 5. A ratchet-wheel 137 having twenty-five teeth is moved step by step. by a pawl 134, on an arm 132 which has a link connection 131 with the rook-shaft 89, so that the passage of an envelope beneath the feelers 23 moves the wheel 137 one tooth. One notch 138 is deeper than the others, and when the pawl 134 enters this notch, a pin 139 on the pawl engages an arm 140 as the arm 132 isrocked. The arm 140 is mounted on a shaft 133 carrying the feeler arm 142, and the feeler is operated to displace an envelope. A spring-pressed brake 150 prevents reverse movement of the wheel 137.

Abstract: 584,294. Wrenches. WARREN & BROWN PROPRIETARY, Ltd. Dec. 23, 1944, No. 25853. Convention date, Jan. 19. [Class 61 (iii)] [Also in Group XIX] A torque-measuring device for a wrench comprises an operating lever (10) with a handgrip (12) adjacent one end and a torquetransmitting head (11) adjacent the other end having means (17, 18) for detachably connecting to it a spanner (19) or the like. Extending from the clamping head 11, with its hook bolt 17, is an arm 10 to which is connected a rectangular calibrated block 20 and a handle 12 formed with a grip to locate the operator's hand to avoid variations in the moment arm. The block 20 carries a slidably adjustable wedgeshaped member 21 with a pointer 24 co-operating with the graduations. When leverage is applied, the arm 10 bends until the wedge 21 engages a plunger 28 which normally retains a spring-loaded trip pin 29. When a predetermined torque is reached, the depressed plunger 28 releases the pin 29 which extends with a " click," thus providing a visible and audible signal. The distance of the head 11 from the centre of the nut or screw can be varied and is set in the desired position by a device comprising a rod 31, the end ,32 of which fits into the head 11. A pointer 34 is held by a spring- pressed ball engaging one of a plurality of circumferential grooves 36 in the rod. A plurality of sets of graduations on the block 20 correspond with the various moment arm settings. In another embodiment, Fig. 9, the clamping head 38 carries a pivot 39 for the lever arm 40, and a spring-urged plunger 41 engages an abutment 42. The tension of the spring is adjustable by rotating the internallythreaded handle 12. Three scales A, B, C are provided as in the first embodiment. As the torque approaches the required amount, the wedge-shaped plunger 41 is forced into the lever arm 40 until it slips over the edge of the abutment 42. The head 11 or 38 may be formed with a socket of the usual kind to receive the usual type of box spanner,

Abstract: 725,915. Telephone and like transmission. STANDARD TELEPHONES & CABLES, Ltd. ( Federal Telecommunication Laboratories, Inc.). Sept. 22, 1953, No. 26104/53. Drawings to Specification. Class 40 (4). In an arrangement in which a number of narrow sub-bands are selected from a voice or other wide-band and are closed up to form a narrower band for transmission, the sub-bands being restored to their original positions at the receiver, the intelligibility is improved by filling the intervening spaces between the restored sub-bands with energy derived therefrom. A carrier wave generator which supplies the modulating carriers at the transmitter also transmits a pilot frequency for providing the carriers at the receiver. After the sub-bands have been restored to their original positions they pass through distortion networks which may consist of pairs of push-pull amplifiers biased to operate on the curved portion of their characteristics. The sub-bands thus widened are fed through filters to remove any overlap and thence to a common output circuit.
