Title: Automatic circular saw machine
IPC: B23D45/18
Filed: 1932-11-21
Abstract: 406,824. Circular - saw machines. WAGNER, K., 12, Opfersteinstrasse, and WAGNER, E., (trading as WAGNER MASCHINEN-FABRIK, G.), 11, Opfersteinstrasse, Reutlingen, Wurtemburg, Germany. Nov. 21, 1932, No. 32915. [Class 145 (ii).] Sawing machine for cutting rods into blanks comprises a circular saw 6 mounted on a carriage 2 which is reciprocated to and away from the work 7 by fluid pressure controlled by a slide valve 9 connected to a slidable rod 20 ; a lug 16 on the underside of the carriage 2 is situated between stops 17, 18 adjustably mounted on a sleeve 19 which is loosely mounted, between abutments 21, 22, on the rod 20. At the end of the forward stroke, the lug 16 engages the stop 17 and moves the sleeve 19 into contact with the abutment 21 on the rod, which is thus moved forward ; at the same time, a roof cam 23 on the sleeve 19 passes under a spring- pressed roller 24 which imparts an extra forward motion to the rod 20, causing the valve 9 to be moved through its neutral position to reverse the carriage 2. Reversal is similarly effected at the end of the return stroke. Alternatively, the sleeve may be fixedly mounted on the rod 20 and so arranged that at the end of the rearward stroke, the valve 9 is moved into its neutral position before the cam 23 passes under the roller 24 ; the carriage 2 will then come to rest at the end of each return stroke, the forward stroke being initiated by means of a hand lever 8 connected to the rod 20, and automatic reversal at the end of the forward stroke taking place as before. The work 7 is fed against an adjustable stop 38 by means of a wheeled trolley 37 moved by a chain 36 passing around a sprocket 32 driven through a friction clutch 33 by a motor x. The work is clamped by an adjustable jaw 15 actuated by fluidpressure controlled by a slide valve 13 mounted on a rod 28 which is normally pressed by a spring 30 in such a direction that the work is clamped. At the end of the rearward stroke of the carriage 2, a plate 25 thereon depresses a roller 27 carried by one arm of a lever 26 the other end of which is connected to the rod 28 ; the work is thus released after each cut to permit it being fed. The vice may be controlled by a hand lever 12 connected to the rod 28. While the work 7 is clamped, the clutch 33 slips ; the clutch may also be opened by a hand lever 35.

Abstract: 822,678. Forming P-N junctions. MULLARD Ltd. Oct. 22, 1957, No. 32945/57. Class 37. An alloy junction is made by applying a freshly-prepared surface of aluminium to the surface of a silicon crystal, heating in an oxidizing atmosphere while maintaining the contact between the aluminium and silicon to provide liquid aluminium-silicon at the surface of contact and cooling to form an alloy junction. A rectangular slice of single crystal of n-type silicon is prepared by applying gold-antimony foil to one of its largest surfaces and heating in an oven to form an n+ region and counterelectrode. This slice is then placed on a silica support and the freshly cut end of an aluminium wire (or gallium aluminium wire) is placed in contact with the untreated large surface of the slice. The wire is applied to the slice under light pressure and the arrangement is heated for 35 seconds in air to about 600‹ C. by means of an electrical heating coil. A conductive connection to the counter-electrode is made by iron-nickel-cobalt wire using a tin-lead solder. The device is then encapsulated in any known manner. The method described may be used to make a PNP transistor.

Filed: 1974-08-01
Abstract: 1418248 Endless conveyers AMF Inc 1 Aug 1974 [15 Nov 1973] 33969/74 Heading B8A Baking pans 10 which are to receive dough from dispensing apparatus (not shown) are fed onto a panning conveyer 14 by a conveyer 12 whose speed is greater than that of the conveyer 14, the pans being controlled by holdback mechanisms 20, 22, proximity sensors PRS1, PRS2 and by a time delay relay TR1. In operation, the sensing of a pan 10a by sensor PRS1 causes a solenoid SOL1 of mechanism 20 to be de-energized and the mechanism to engage the pan, the conveyer 12 continuing to operate and to cause accumulation of the remainder of the pans. When a start-pan-feed switch (line 8, Fig. 5) is closed by an operator, solenoid SOL1 of mechanism is energized and pan 10a is released for transfer to conveyer 14 where it is engaged by lowering of mechanism 22 in response to sensing of the pan by the sensor PRS2. Simultaneously operation of a limit switch LS1 on an arm 26<SP>1</SP> of the mechanism 22 causes a time delay relay TR1 to be energized. While pan 10a is being held, a second pan 10b is sensed by sensor PRS1 and is held by mechanism 20, Fig. 2. At the end of the delay period, mechanism 22 is raised, pan 10a is released and, in moving beyond the sensor PRS2, causes the latter to be deactivated and mechanism 20 to raise and release pan 10b. This pan is then held on conveyer 14 by operation of sensor PRS2 and mechanism 22 to provide spacing S between the pans. This spacing is selected by adjusting the time delay, the position of the sensor PRS2 or the spacing between the holdback mechanisms 20, 22. In a modification of the Fig. 5, circuit, the need for the operator to actuate the start-panfeed is eliminated.
