Title: Improvements in or relating to electric circuit controls
IPC: H01C10/32
Filed: 1948-11-08
Abstract: 649,434. Variable-contact resistances; combinations and sets of resistances. STEVENS, A. H. (Stackpole Carbon Co.). Nov. 8, 1948, No. 28948. [Class 37] In a radio volume or tone control, provided with a metal hub 11, Fig. 3, above and flush with an insulating collar 9 with both rotatable with control shaft 3, the hub 11 integral with a control head or flange 12 bearing conductively the slider 17 is encircled by a wire loop 24, Fig. 4, formed at one end of a spring wire 22, whose other end is secured to the base 1 and terminal tag 21 in a plane offset from the plane of the hub 11, whereby the wire loop 24 tends to cant, Fig. 3, between the hub flange 12 and the insulating collar 9 and thus exert pressure continuously against them at diametrically opposite points. The pressure of the wire loop 24 against the flange 12 ensures low contact resistance and thus satisfactory conductivity between the slider 17 and the terminal 21, and the pressure of the loop 24 against the collar 9 provides the necessary friction to hold the control shaft 3 in any position to which it is turned regardless of how light the pressure of the slider 17 against the resistance track 4 may be. The slider 17 comprises a pair of spring contact fingers, Fig. 4 and Fig. 2 (not shown) projecting towards each other from opposite sides of the control head or flange 12 and having downturned ends engaging the resistance track. With each unit of a tandem assembly of volume and tone control, Fig. 4 (not shown), constructed to include wire 22 with canted loop 24, it is not necessary to provide friction washers between the two shafts.

Title: Amplifier Circuit
Inventor: JULIE LOEBE
IPC: H03F3/32
Filed: 1968-06-19
Abstract: 1,166,009. Valve and transistor amplifying circuits. JULIE RESEARCH LABORATORIES Inc. 19 June, 1968, No. 29146/68. Headings H3T and H3W. In a single-ended push-pull amplifier valve 23, which has a cathode bias impedance 45 which may comprise a resistor, is connected in series with power supply 53, controlling means 51 and the load 35. A second valve 25 has its cathode connected to the load 35 and its anode to the other end of the load via a second power supply 49, and is driven from the controlling means 51 via bias means 47. Controlling means 51 may comprise a resistor, a forward-biased diode, or an active device such as another valve. The arrangement, Which is characterized by possessing only three terminals, i.e. input terminal 5, output terminal 7 and common terminal 9, may use transistors instead of valves. Each valve may be replaced by a number of valves in parallel to increase the power output: in the case of transistors a greater output voltage swing may be obtained by replacing each transistor with several connected in series. If terminal 7 is earthed instead of terminal 9 and the output taken from terminal 9, a cathodefollower type circuit of unity gain and low output impedance is obtained. Alternatively terminal 5 may be earthed and the input applied to terminal 9, giving an arrangement of the grounded-grid type. The Specification also describes a circuit for the power-supply 53 which has both its terminals floating above earth (Figs. 3, 4, not shown): a mains transformer supplies a bridge rectifier circuit which is followed by a #-filter, and choke is placed in either side of the output from this. A-capacitor is connected across the final output terminals of the power supply, while each of the chokes is shunted by a filter network to suppress the effect of resonances between the chokes and stray capacitances of the mains transformer.

Abstract: 984,833. Making composite sheet; jointing by rolling. COMPOSITE METAL PRODUCTS Inc. Aug. 2, 1962 [Aug. 8, 1961], No. 29705/62. Headings B3A and B3M. A method of cladding aluminium with stainless steel comprises mechanically removing all oxide from the bonding surfaces of the aluminium and steel sheet bringing the cleaned surfaces together and heating them under non- oxidizing conditions to a temperature above the recrystallization temperature of the aluminium but below its melting point and below the recrystallization temperature of the stainless steel and applying pressure to unite the sheets. Two sheets of 0.125 thick aluminium and two sheets of 0.010 stainless steel are mechanically cleaned, e.g. wire brushed, on one side to remove all oxides and stacked so that the aluminium sheets form the outer layers and the stainless steel sheets, which are arranged with their uncleaned faces in contact, form the inner layers. The ends of the stack are resistance or torch welded, the pack heated to between 650‹-1100‹ F. in a vacuum or inert atmosphere and rolled, forged, pressed or formed by explosive or atmospheric pressures to effect a 25% reduction and a thickness of 0.101. Since the uncleaned surfaces of the stainless steel will not bond under pressure a pair of clad sheets are produced in one pass. In another embodiment single or double composite sheet is produced by a continuous rolling process in which aluminium and stainless steel strip fed from reels is mechanically cleaned, pressed together by driven pinch rolls, spot welded to maintain the strips in alignment, heated in one or separate furnaces in a vacuum or inert atmosphere of argon, helium, hydrogen or nitrogen and roll bonded together. The aluminium or alloys thereof may be in the annealed or cold worked state and stainless steel in the ferritic or martensitic state may be used. Tables are given showing the mechanical properties of the composite material. The material may be used for making cooking vessels. U.S.A. Specifications 2,718,690 and 2,758,368 are referred to.

Abstract: 695,685. Securing handles on shafts. BOLINDERS FABRIKS AKTIEBOLAG. Dec. 19, 1951 [Dec. 23, 1950; May 31, 1951], No. 29788/51. Class 80 (ii). The handle 4 of a mincer is removably clamped on the end 3 of the feed spindle by a set screw 15 having a clamping head 5, Fig. 13, of a special shape which when rotated back to another position, Fig. 15, allows the specially shaped hole 10 in the handle end 9 to slip over the set screw head 5 so that the handle can be removed without removing the set screw. In Fig. 7 the pressing part 12 is D-shaped and is eccentrically mounted relative to the similar shaped hole in the handle. Fig. 2 shows another construction in which the headed set screw 15, 16 has also a fixed rounded pressing portion 17 with tail or projection 18 matching a hole 10 in the head 9 of the handle so that in matching position the handle can be removed by sliding its head over the set screw. When tightening up the screw 15 by its grip 16 to press the tapered hole 10 of the handle over the like shaped end 3 of the feed screw, the tail 18 slides around the abutting face 14 of the handle head. This face 14 may have a gradient 20 clockwise over its surface to give a frictional locking without great accuracy of thickness 19 of the handle head. The gradient ends in a step 24 from the height 23 to the lower height 21. In Fig. 9 the set screw is replaced by a headed pin 27 retained permanently in position by a pin 29 in a groove 28. Either the groove 28 may be helical or the surface 14 may have a gradient 20 to give frictional locking with the abutting face of 18. The handle 4 may also be used to tighten the clamp 35 on a table 33, Fig. 1.
