Abstract: 361,771. Wire resistances. STREATIT-MAGNESIA AKT.-GES., 18, Breitestrasse, Pankow, Berlin. March 17, 1931, No. 8195. Convention date, March 31, 1930. [Class 37.] In a radiator or heater in which a helically or similarly wound resistance wire is mounted on an insulating support, the resistance wire a is wound so as to present a C- shaped profile or end view and embraces a T-shaped or similar projection b on the support c. Each turn is thus anchored to the support, and lies wholly on the surface. The wire may be shaped by first winding a round or similar profile and then bending to C-form, or each turn of the wire may be separately bent to shape during winding. Hard wires, e.g. of chrome nickel, may be bent while red hot. The support c may be of grid shape or may have separate openings or depressions. It may be composed of separate strips with T-shaped or similar projections. Forms of winding other than helical may be employed, e.g. flat or zig-zag wound wire may be bent to a C-shaped profile.

Title: Improvements in machines for uniting metal sheets and the like by means of staples
IPC: B21D39/03
Filed: 1938-03-18
Abstract: 512,946. Stapling, COLDITZ, L., (trading as BREHMER, GEB.). March 18, 1938, Nos. 8432 and 8433. Convention dates, March 18, 1937, and March 9, 1938. [Class 89 (iii)] A machine suitable for uniting, by means of staples, metal or like sheets of small thickness and high resistance, drives short-legged staples by means of a driver the stroke of which is short and powerful, the staples being guided in a closed guide during driving. The power of the stroke is increased during the period of actual penetration of the work by the staples. Wire fed in by a lever 16 is bent over an inside former 12 by an outside former 11 actuated by a cam 8. The staple length is severed by a cutter 20 actuated by a cam 10. The driver 15 is actuated by a crank 6 which engages a slot 6<1> of such form that the driving force is increased while the staple is penetrating the work. The same result may be achieved by the provision of a separate toggle or like drive operative during this period. The staple, during driving, is wholly enclosed between the driver, the bending grooves in the former 11, and a member 28<1> which is held between the staple legs by a spring 31 and is progressively withdrawn as the staple is driven. The staple legs are clenched outwardly by a fixed die 32 in the work support 5. The later is accurately adjustable towards the stapling head by means of a worm gearing and an eccentric. Preferably, the work is pressed after stapling, so that the staple back is forced into the upper face of the work, to give a flush surface. In a modification, Figs. 17 and 18, the engaging parts of the stapling head and work support are curved, so that the work becomes curved before the staple is driven. The work support 110 is provided with narrow slots 111 into which the staple legs pass, and by which they are guided, after penetrating the work. The legs are clinched by moving dies 112, 113 which are reciprocated vertically at the appropriate time. The machine may be adapted for use with preformed staples. Specification 246,712, [Class 89 (iii)], is referred to.

Filed: 1924-04-04
Abstract: 237,638. Capon, A. L. H. April 4, 1924. Tuning-apparatus, construction and control of; thermionic amplifiers and detectors. - The aerial and intervalve circuits of a multivalve receiver are simultaneously tuned by means of a system of press-button switches, which may also be used to control the number of low frequency amplifiers in circuit, or to throw the set as a whole m or out of action. As shown in Fig. 1 the aerial inductance 8 is divided into several sections 8<0>. 8<1>, 8<2> &c. A series of push-buttons 9, 9<1> are mounted on a control box as shown in Fig. 6 so that when, say, the button 9 is depressed contact is made between the points 10, 12, and the segments 8<1>, 8<2> &c. are shorted to earth, leaving the segment 8<0> alone in circuit. Normally the segments are held in series through a contact 11. Similar contacts 13, 13<1> are arranged to control the plate resistances such as r through a second series of push-buttons mounted on the same control box (not shown) and interconnected with the push-buttons 9. Associated switch buttons 14, 15 insert the telephone receiver 21 in the plate circuit of the amplifiers 4 or 5 at will. When the button 14 is depressed, the contacts 16, 17, Fig. 4, are closed to ignite the filaments of valves 1 to 4; the contacts 18 and 19 bring the telephone into the plate circuit of valve 4: whilst the contact at 19, leading to the primary of the transformer between valves 4 and 5 is broken. Each series of push-buttons A, Fig. 6, is so arranged that as any one of that series is depressed it moves outwardly a swinging plate L, and so automatically releases the other buttons. A master button shaped as shown in Fig. 7 switches off all the valves simultaneously and so puts the receiver out of action.

The produce is fed to them by the usual cutting and conveying devices beneath the rotors 8, 9 is an inclined collector grain pan 14 which conveys the grain falling through the concave 12 to a transfer pan 15 and hence to a cleaning device 16. The grain pan 14 is carried on swinging links at the forward end and is oscillated by a crankshaft 89 driven by the engine. The reciprocating movement is also transmitted by a push rod and double swinging arm to the upper shoe 63 and the long shoe 65, which shoes, together with the fan 17 form a conventional cleaning device. After cleaning, the grain passes down into the trough where an auger 18, an elevator 19, a conveyor 20 and a transverse auger 49, transfer it to the grain tank 21. The tailings are transferred by an auger 22 and an elevator 23 and are distributed by an auger 24 between the rotors 8 and 9. The straw is discharged from the rotors 8, 9 along the direction of the arrow P. The grain tank 21, which may be removable is tailored to suit the space available and is emptied via an opening 50 and a pivottable discharge tube 25. The. opening 50 is extended into the bottom of the tank by a fixed tube containing an auger. The engine is located in the area 26 and drives the rear wheels 7 via a variable transmission device, the front wheels being steerable. The engine also has on its drive shaft 86 a number of pulleys which drive the rotors, the conveyors the augers, the oscillating shoes and the hydraulic pump.  Fig 1 also indicates in broken lines, the outline of a conventional combine for comparison purposes.

Class 131 A high stubble comb for sheep shears, use of which leaves the pelt unridged, comprises teeth projecting from the front edge of a body portion and a runner dependent from each tooth, the lowermost parts of the runners lying on an arcuate line concave to the plane of shear formed by the tops of the teeth. As shown, the upper surfaces of comb teeth 24, projecting forwardly for equal distances from a body 12, form a flat plane of shear PS on which a cutter 14 reciprocates, the free ends of the comb and cutter teeth lying on arcs AB, CD, respectively, and the lowermost parts of the runners 32 being of convex rocker shape and lying on an arc EF. Due to the horizontal and vertical offset of the runners (see Fig. 3) the line PT represents the only common plane to which the runners are tangent but ridging of the pelt does not take place even when the angle between the comb and the hide is decreased since the hide is stretched in chordal relation between the end teeth nor when the angle is increased because the arc CD is of. less radius than the arc AB. In a modification the plane of shear is curved convexly and the runners are of equal height.
