Title: Drying apparatus for grain
IPC: F26B9/08
Filed: 1973-11-26
Abstract: 1416748 Grain dryers S YAMAMOTO 26 Nov 1973 54809/73 Heading F4G Grain drying apparatus comprises a cylindrical chamber 1 having a perforated lower plate 6 through which air is blown from a supply means 7 to the grain which heaps on the plate, and an auger 12 revolvable about its own axis and about the vertical axis of the chamber 1 which gathers the grain and moves it centrally to an opening 9 where it is collected and recycled to the top of the chamber. As shown, grain is delivered to the top of the chamber 1 by a bucket conveyer 5 and tube 4 and falls on to a distributer 30 attached to a pole 33 driven by a motor 34. Bucket conveyer 5 is driven by a motor 29 which through shaft 24 and transmission wheel 26 drives a screw conveyer 10 feeding the bucket conveyer 5. Auger 12 is driven by a shaft 21 through bevel gears 20, 22, sun gear 19, planet gear 17 and gear 36, the rotation of the latter being adjustably resisted. Thus auger is thus caused to rotate around its own axis and about the vertical axis of the chamber as planet gear 17 rotates around sun gear 19, the gear-box 15 containing gears 36, 19, 17. To adjust the rotations of gear 17, according to the quantity of grain to be dried, gear 36 is provided with a shaft 37 to which a disc 39 is attached. Disc 39 rotates within a box 38 formed at the lower end of pole 33 and containing resistance materials 40, such as sand, the amount of which may be adjusted by addition or removal through a plug 42.

Title: Cross-bar switch
IPC: H01H67/26
Filed: 1969-11-11
Abstract: 1292305 Electric selectors ARTHUR G RUSSELL CO Inc 11 Nov 1969 [13 Nov 1968] 55100/69 Heading H1L In a cross-bar switch in which a contact set is selected by rectilinear movements of a select bar and a perpendicular connect bar, the latter comprises two oppositely movable bars one of which operates on an overcentre mechanism so as to latch a contact-set on and the other one of which operates on the overcentre mechanism in an opposite sense so as to release the contactset. The latter consists of fixed printed circuit contacts and movable spring strip contacts. As shown a printed circuit board 16 carries an edge connector 20 at one end for readily cooperating with a rack and a bracing strip/ carrying handle 26 at its opposite end. Along the remaining edges are disposed two L-shaped yokes 104, 104<SP>1</SP> for the two sets of connect magnets 100, 100<SP>1</SP> associated with the pairs of connect bars 90, 92, these yokes further serving to stiffen the board. Insulating bridges 44, 42 are " popped " into suitable apertures in the board above each row of contacts 14. A resilient over-centre mechanism 40 depends from the bridge at each contact set. Each bridge supports a select bar 60 for rectilinear movement under control of a select magnet 70. The bars are spring-loaded as at 62 and contain slots 68 through which project ears 66 formed integrally with the bridge and serving to limit movement of the bars. In addition, at each contact set position a pair of resilient arms 82, 84 depend from opposite sides of the bar. The spring- loaded (96) connect-bar-pairs are supported in wedge shaped pillars 94 and are moved by pivoting armatures 102, 102<SP>1</SP> which are restrained in recesses in the upper edges of the yokes by a clip-on cover 112. In operation, a select magnet 70 is energized thereby moving its select bar 60 to the right and thus causing the ends of its arms 82, 84 to enter windows formed in the crossing connect bars. Thereafter a connect magnet 100<SP>1</SP> is energized so as to move forward its one 90 of the connect-bar-pair. The over-centre mechanism 40 operates so as to move the contacts 32 into a closed position. Both magnets are de-energized and both bars restore. In order to release a connection bar 60 is again moved but this time a magnet 100 is energized and hence a bar 92 is moved thus re-operating the over-centre mechanism 40 so as to open the contacts. Fig. 3 depicts an M-shaped bifurcated contact strip 30 which is anchored at one end 34 in the circuit board 16 and which slidingly engages a fixed contact 14 at its other end. As shown, arm 82 of select bar 60 has been forced against an articulated resilient flap 40, which is formed integrally with the overlying bridge (42), by the left-to-right movement of connect bar 90. When the latter returns to rest, flap 40 maintains the contacts closed. When bar 92 later moves from right-to-left arm 84 of select bar 60 will be forced against flap 40 so that it will snap-over centre and allow contact 36 to disengage from contact 14. In so doing it may engage a backcontact (Fig. 5, not shown).

Abstract: 1310300 Seaming non-metallic sheet material R A JONES & CO Inc 4 Dec 1970 [13 April 1970] 57795/70 Heading B5K [Also in Division B8] In a method of sealing thermoplastic film in which a continuous web of film is moved past a heated sealing element at a variable speed, the sealing element exerts a pressure on the film which is directly proportional to the speed of the film. As shown in which packs of six cans 12 and a film of wrapping material 17 are moved by a conveyer 11 past a sealing station 13, the film passes over a former 18 and is wrapped about the cans with its edges overlapped about a mandrel 19 disposed below the film at the station 13. Sealing is effected by a heated double, rimmed wheel 55 mounted on a shaft 42 carried by a lever arm 52 pivoted upstream of the arm. Engagement and disengagement of the wheel 55 with the moving film is controlled by two pneumatically operated piston and cylinder arrangements 61, 60, the pressure exerted by the cylinder 61 being controlled by a speed sensor 36 which is driven at a speed proportional to that of the machine and the output pressure of which is applied to the cylinder 61.

Synthetic yarn is produced in a continuous manner by melt-extruding fibre-forming polymeric material through apertures arranged in one or more rows to form one or more sheets of continuous filaments, stretching the filaments while in the form of a sheet by gas streams discharged from slots one on each side of the or each row of apertures and adjacent and parallel to the or each row and leading the or each sheet of filaments together with its associated gas streams through an open-ended duct through which the filaments and gas pass without turbulence, the filaments being stretched and set whilst being kept parallel to but separate from one another, and collecting the filaments into bundles and subsequently forming the bundles of filaments into a yarn, e.g. by entangling or twisting and/or further drawing, which may precede the entangling or twisting or by taking up the bundles in rotating cans. The polymeric material may be extruded at a temperature not more than 20‹ C. above its melting temperature, the gas streams may be air streams and may be at the temperature of the melt or at a higher temperature and under pressure such that the air streams expand and cool adiabatically. The filaments may thus be stretched at a stretch ratio of at least 30 while travelling through a distance within 5 mm. of the apertures, the temperature of the air streams being such that all the molecular orientation obtained by this stretching is frozen in, and then leading the or each sheet of filaments, together with its associated air streams, through an open-ended duct. The filaments may have a denier of 1 or less than 1.
