Abstract: 1,260,977. Pedestal transistors. INTERNATIONAL BUSINESS MACHINES CORP. 4 Nov., 1970 [10 Nov., 1969], No. 52370/70. Heading H1K. A monolithic integrated circuit pedestal transistor (Fig. 2) comprises a P-type wafer 36 on which is formed a N<SP>+</SP> pedestal collector region 38 and an epitaxial N- collector region 40. A P-type base region 42 and N<SP>+</SP> emitter 44 complete the structure, and a diffused isolating P-type region 46 on each side of the pedestal separates it from other adjacent monolithic integrated circuit devices outwardly of the isolation. Axes A, B bound the internal operating zone, and lie inwardly of the extrinsic zone which may accommodate e.g. metallized contacts. Overall collector base capacitance and base widening effects are reduced so that the monolithic geometry may be decreased. In a fabrication, a P silicon substrate is coated thermally with oxide layer selectively etched over photolitho to leave oxide pedestal 58, and a further oxide coating is thermally applied, after which it is selectively etched to leave a thicker pedestal 64. Further selective etching forms the silicon substrate into wafer 66 with pedestal 70 (Fig. 6). A thermal oxide layer 72 is formed and selectively etched to leave diffusion opening 74 into which a N<SP>+</SP> sub collector region 76 is diffused to form a concentrated N<SP>+</SP> pedestal 78 (Fig. 7). Oxide 72 is removed, and epitaxial layer 80 is grown over region 76 and covered by oxide layer 82. The resultant pedestal is etched off through a mask, leaving N- region 83 between oxide layers 86, 88 (Fig. 9). Region 83 is converted to oxide, and layers 86, 88 are built up to layers 90, 91 (Fig. 10) after which they are removed by etching leaving a flat epitaxial layer 92 into which conventional base emitter diffusions form P-type base region 96 and N<SP>+</SP> emitter region 98. An N<SP>+</SP> reach through diffusion 100 connects to sub collector 76 (Fig. 12). Other insulant materials e.g. silicon nitride may be admixed with the oxide.

Abstract: 1,193,990. Semi-conductor switching circuits. ARROW ELECTRIC SWITCHES Ltd. 4 Dec., 1967 [24 Feb., 1967], No. 55033/67. Heading H3T. [Also in Division H2] A static switching circuit comprises a semiconductor controlled rectifier (e.g. thyristors 40 or 41) arranged to be turned on by a D.C. voltage derived by rectification of the secondary voltage of a transformer 70, the primary of which is controlled by a further thyristor or bi-directional static switch. As described, when switch 10 is closed, the A.C. supply is rectified at 11, smoothed by components 12, 13 and stabilized by a Zener diode 15. This voltage is used to charge capacitor 21 at a rate depending on the setting of variable resistor 19. After a predetermined time, unijunction transistor 80 is triggered, turning on thyristor 25 which in turn, triggers a bi-directionally conductive switch 90 which energizes the primary winding of transformer 70 from the A.C. supply. Respective half cycles from the secondaries are rectified at 30, 31 and provide D.C. control voltages which turn on the thyristors 40, 41, energizing a load (such as a motor). Unijunction transistor 80 and capacitor 21 may be arranged to oscillate at a frequency greater than that of the A.C. supply in which case thyristor 25 may be omitted.

Abstract: 1,177,348. Acoustical panels. NATIONAL GYPSUM CO. 9 Dec., 1966 [27 Dec., 1965], No. 55363/66. Heading B2K. A method of forming a laminated fissured acoustic panel having a porous surface layer bonded to a dense backing layer comprises mixing granulated mineral wool with a starch binder solution to form a wet, castable mix having a consistency capable of having fissures formed therein, depositing the mix on the surface of a gypsum board backing layer, levelling and opening fissures in the said wet mix by moving the wet mix under a horizontally oscillating screed bar which has a component of oscillation perpendicular to the flow of the wet mix and which extends across and is in contact with the wet mix, to form a fissured wet laminated panel, and drying the wet laminated panel at a temperature and for a sufficient time to maintain the core hardness of the gypsum board backing layer not less than 20. Two oscillating screed bars may be employed, the first being perpendicular to the surface of the backing layer and oscillating across the surface of the wet mix to level the wet mix and form a wet layer having a thickness slightly greater than the desired finished thickness of the surface layer and a second screed bar levelling the wet mix to a uniform desired thickness by oscillating across the surface with a component oscillating perpendicular to the flow of the wet mix and being positioned to fixed inclined angle to the surface of the layer. This bar may be inclined at 15 to 60‹. The thickness of the surface layer may be from 3/16th in. to ¢ in. The binder solution may contain clay, a thickener, such as hydroxypropylmethyl cellulose, ethylene-oxide polymers and guar gum derivatvies, and boric acid and may have a water content of 90- 95%. This binder solution may be mixed with the mineral wool in the ratio of from 3 to 4 parts of binder solution to one part of mineral wool.

Abstract: 1358610 Transistor switching circuits ITT INDUSTRIES Inc 1 Dec 1972 [2 Dec 1971] 55473/72 Heading H3T [Also in Division G1] A threshold circuit having a light-emitting diode to indicate its state, is characterized in that the forward voltage drop across the lightemitting diode is used as the reference or threshold level for the circuit. In the preferred embodiment, Fig. 3, the voltage to be monitored is applied to the left-hand terminal A of a differential amplifier having a common emitter load R e , and the forward voltage dropped across a light-emitting diode LD is applied to the right-hand input B. In operation a small standing current is allowed to flow through the diode LD by a resistor R so as to provide the reference potential to point B, this small current being insufficient to make the diode glow. When the voltage to be monitored on terminal A rises above the reference voltage a transistor T4 conducts causing sufficient additional current to flow through the diode to cause it to glow, thereby indicating the change of state of the threshold circuit.

Abstract: 1378647 Bundling envelopes; feeding sheets PAK-WELL CORP 6 Dec 1971 [21 Dec 1970] 56497/71 Headings B8C and B8R [Also in Divisions B6 and B2] A continuous assembly of envelopes 12 having removable side margins is formed by conveying the envelopes past applicator wheels 22 which apply adhesive to the side margins, and securing the envelopes together in overlapping relationship or to lateral reinforcing strips or to a carrier web. Feeding envelopes.-Envelopes 12 are picked up from a supply station 10 by a pair of suction wheels 14. The foremost envelope at the supply station is maintained in a position substantially tangential to the suction wheels 14 by means of a sensor switch 40 which controls the drive of a plurality of belts 38 upon which edges of the envelopes rest. The suction wheels 14 and a pair of belts 16 transfer the envelopes 12 serially on to a pair of inclined conveyer chains 18 which carry the envelopes past the adhesive applicator wheels 22. Adhesive application.-The applicator wheels 22 rotate in a reservoir of adhesive and doctor blades remove adhesive from all but the surface of a segment (48, Fig. 3), of each wheel 22, which surface includes a plurality of spaced apertures. The lengths of the dotted strips of adhesive applied to the envelopes may be adjusted by disengaging a clutch between a drive from the conveyer chains 18 to the wheels 22 so altering the phase relationship between the rotation of the wheels 22 and the linear movement of the conveyer chains 18. Associated with each applicator wheel 22 is a resilient movable member (44, Fig. 3) capable of selectively deforming a side margin of each envelope so that it contacts the applicator wheel 22. Interconnecting envelopes.-The envelopes, upon discharge from the conveyer chains 18, are engaged by drive rollers 24 and drawn towards the nip of pressure rollers 26. In the embodiment of Fig. 1, the peripheral speed of the pressure rollers 26 which is slower than that of the drive rollers 24, is adjusted so that the envelopes are overlapped and hence secured together in this relationship. In alternative embodiments (Fig. 1A), the envelopes are secured in overlapping relationship to one another and to lateral reinforcing strips (56) or they are secured in spaced relationship on a carrier web 60. Perforating and trimming.-Pairs of matched punch wheels 28, 28a perforate the margins of the interconnected envelopes and pairs of rotary knives 32, 32a trim the edges of the envelopes. The various components of the machine are adjustable to accommodate envelopes of different sizes.
