Title: Adjustable operating point snap acting switch
IPC: H01H37/12
Filed: 1965-11-26
Abstract: 1,084,880. Thermal switches. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Nov. 26, 1965 [Dec. 2, 1964], No. 50288/65. Heading H2B. A thermally-responsive element such as a bi-metal 85 actuates a snap-action switch (see also Figs. 2, 4 and 5, not shown), via a pinplunger assembly (36), 37 (see Fig. 2, not shown particularly) comprising a threaded pin (36) and an elongated threaded nut 37 on the pin, the nut 37 being freely slidable in a passage (43) of a bushing (42) mounting a dial plate 40 of an adjustment mechanism (26) and also rotatable on pin (36), when plate 40 is turned, to adjust the operating point of the switch by altering the length of the pin-plunger assembly. The housing 20 thus carries the weight of mechanism 26 and the pin-plunger assembly or actuator is not loaded by the inertia of mechanism 26. Rotation of a shaft 88 by a knob 90 rotates a gear 87 meshing with a gear (46) associated with dial plate 40 and thereby turns nut 37 on threaded pin (36). Alternatively, an electromechanical stepping device may be used. Nut 37 is restrained to rotate only one turn (approximately 360 degrees) by a tab (80) on dial plate 40 engaging a lug (81) on an index plate (48), (Fig. 2, not shown).

Abstract: 1,127,161. Transistors. SIEMENS A.G. 30 Nov., 1965 [1 Dec., 1964], No. 50687/65. Heading H1K. In a transistor with a diffused base zone arid an alloyed or diffused emitter zone the portion of the base zone lying between the emitter and collector zones is produced by a multiple stage diffusion process, in at least one stage of which the semi-conductor surface is partially masked, so as to have a varying thickness or doping concentration along a line parallel to the emitter junction. In devices produced by mesa or planar techniques the thickness and/or doping may vary periodically as in Figs. 4 and 3 (not shown), respectively, or the thickness and doping may increase stepwise outwards from the centre of the emitter junction (Figs. 1, 2 and 5, not shown). The variations in doping and thickness, of the base zone are achieved by performing the diffusion in two or more stages with appropriate parts of the semi-conductor surface masked during at least one stage. The collector zone may in all cases comprise a heavily doped substrate of silicon or germanium with a thin high resistivity epitaxial layer in which the base zone is formed.

Abstract: 1,090,149. Lift control systems. TATEISI ELECTRONICS CO. Dec. 14, 1965 [Dec. 21, 1964], No. 53053/65. Heading B8L. When a lift-car moves upwardly to serve the second floor, a proximity detector SA passes a metallic plate M1 in a central position between the first and second floors, whereupon a pulse from shaping circuit SC is applied to reversible counter RC so that a signal on line L1 is transferred to the line L2. The pulse from the circuit SC is also passed through timers TM1- TM3, having different delay-periods, to AND- gates A1-A6. Call-signals are applied selectively to terminals C1-C6, the terminal C2 for the second floor being effective in this instance. Since the signal on line L2 constitutes a third input to gate A2, the latter produces an output at terminal S2 for reducing the speed of the car as it approaches the second floor. Movement to the other floors is effected in a similar manner, the different settings of the timers TM1-TM3 making allowance for differences in the distances between adjacent pairs of successive landings. The timer TM1, for example, comprises multivibrator MV1 in series with differentiator D1 and rectifier R1, a positive pulse from the multivibrator, in response to a signal from circuit SC, having a duration corresponding to a predetermined delay period. At the beginning of said period, the differentiator produces a positive pulse, and, at the end, a negative pulse, the former being suppressed by the rectifier.

An adjustable shelving assembly comprises a shelf 10 supported by posts 34 passed through apertures 18 in the shelf 10, each post 34 being engaged by a frusto-conical, split collet 40, 42 which is adjustably positioned along the length of the post 34 and which seats in a corresponding bore 32 in a support member 20 secured to, or integral with, the shelf 10 whereby the collet 40, 42 is clamped on the post 34 due to the wedging effect between the member 20 and collet 40, 42 under the weight of the shelf 10. As shown, the member 20 is fitted beneath a corner of the shelf 10 and has limbs 28, 30 riveted, as 22, 24, to shelf flanges 12, 14. The collet 40, 42 is held on the post 34 by a spring clip ring 48 engaged in collet groove 46 and has an internal rib 44 engaged in a selected groove 36 in the post 34. In another embodiment (Figs. 6, 7) the rib 44 is replaced by a plurality of grooves (50) selectively engaged by a ring (52) acting as a rib. In a further embodiment (Fig. 11), the post (34A) and collet 40A, 42A) are free of ribs and grooves so that the collet is located solely by friction on the post. In a modification (Figs. 9, 10) the shelf (60) is of plastics and has collet receiving bores (62) provided in integral corner parts.

Abstract: 1,245,807. Automatic position control. INTERNATIONAL BUSINESS MACHINES CORP. Nov. 11, 1968 [Nov. 13, 1967], No. 53256/68. Heading G3R. [Also in Division B3] An electrode resiliently coupled to a holder is oscillated to intermittently contact an electrically conductive surface which it works, and the position of the holder relative to the surface is maintained constant by automatic adjustment in dependence on the intermittent contact. In Fig. 6, a D.C. source 39 is connected between a workpiece 12 and an electrode 13 which is lowered towards the work by a reversible electric servomotor 30 operating through a screw and nut drive, and vibrated with small amplitude into intermittent contact with the workpiece by a resiliently, rubber, mounted armature within a solenoid 48 supplied from an A.C. source (not shown) of constant high frequency which is adjusted to obtain mechanical resonance. The workpiece is mounted on a platform (not shown) which is reciprocated in one direction by a motor drive and continuously moved in a direction at right angles or a direction determined by a digital programme by another motor so that desired areas of the workpiece are converted to an alloy of, for example, tungsten carbide, gold or chromium by the use of a suitable electrode. A changeover switch 65 is moved to the opposite position from that shown to over-ride a limit switch 74 and condition a D.C. transistor amplifierlimiter 64 so that its output is of such polarity as to cause motor 30 to lower the electrode. Limit switch 74 then closes, and switch 65 is centred so that, when the electrode reaches the workpiece, amplifier 64 is responsive to the intermittent voltage at 61 due to the intermittent contact between the electrode and the workpiece. The amplifier compares the mean value of this voltage with a reference and controls servomotor 30 to maintain the difference zero so that the mean position of electrode 13 is maintained at a constant distance from the workpiece despite contours. Upon completion of the work, switch 65 is moved to its upper position shown to cause servomotor 30 to lift the electrode away from the work until limit switch 74 opens.
