Title: Rolling mill
Inventor: KLENZ KARL A
IPC: B21B15/00
Filed: 1954-09-22
Abstract: 775,289. Making strip metal. LANDO PRODUCTS, Inc. Sept. 22, 1954, No. 27464/54. Classes 83 (2), 83 (3) and 83 (4). In a continuous rolling-mill for strip-metal, an edge-trimmer 27, Fig. 1, between the first and second stands 21, 50, has opposed yieldable cutting-edges to remove irregularities or cracks in the side-edges of the strip 14 prior to further rolling. Planing. The edge-trimmer 27 described in Specification 775,290, comprises a tunnel-shaped guide 28, Fig. 3, for the strip, having opposedslots 31 in which blade-holders 34 with projections 32 engaging the slots 31, are slidable. Blades 33 are adjustable in the holders by screws 38 and are yieldingly held in engagement with the strip-edge by an " H " frame 39, Fig. 3B, having legs 43 engaging ball-sockets 46 in the holders 34 and drawn together by springs 44 so that both holders 34 have a floating action. The holders include shoes 36 which engage the strip-edges to provide a constant depth-of-cut by the blades. Rolling. A tensioning device 47 is provided between the first and second roll stands and comprises a hinged guide 51 through which the strip passes from under a fixed roll 48 and over a roll 49 which is yieldingly held in the raised position. Movement of the roll 49 is dependent upon the slackness of the strip and this movement is used to control the speed of the first mill stand through a cable and rheostat (not shown). A camber indicator 57 provided on the last mill stand 50 comprises a vertical pointer (not shown) attached to a pair of rolls mounted close together and engaging the surface of the strip. Shearing. Shears 19 for severing the strip as required by operation of push-buttons 88 at each .end of the mill, comprise a pair of freelyrotatable rolls 89, 90, Fig. 8. The upper roll 90 is weighted on one side and carries a knife 93 which is normally held in the vertical position by a solenoid 94. On operation of the pushbuttons 88 the knife 93 swings down to engage and sever the strip against the lower roll 89. Manual resetting is provided through a gearconnection 96. Winding and reeling. The strip 14 is initially fed from a pay-off reel 13 mounted on a pivoted support 12 and passes through a centring device 16 comprising adjustable vertical and horizontal rolls 17. The finished strip is reeled on a coiler 66 with a retractable hub 69 and a flexible beltwrapping device 70 as described in Specification 759,332.

Title: Monolithic Semiconductor Microcircuits with Improved Means for Connecting Points of Common Potential
IPC: H01L27/04
Filed: 1967-06-15
Abstract: 1,154,805. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 15 June, 1967 [1 July, 1966], No. 27647/67. Heading H1K. In a monolithic integrated circuit comprising a body of semi-conductor material having a relatively low conductivity substrate of one conductivity type surmounted by a layer of the opposite conductivity type containing at least some of the circuit components, connection of various component electrodes to a common potential is achieved by providing a relatively high conductivity layer of semi-conductor material of the first conductivity type on the lower face of the substrate and electrically conductive means extending through the substrate and the opposite type layer. The electrically conductive means may comprise the isolating regions surrounding the components. As shown, Fig. 2, a relatively low conductivity P-type silicon substrate 18 is provided with a P + type layer 16 and an N type layer 20 by epitaxial deposition. Circuit components, such as the bipolar transistor 22 and the resistor 31 are formed by appropriate diffusions into the N type layer 20 and are isolated by P + type regions 36, 38 diffused completely through the N type layer 20 and the P type substrate 18. The emitter region 26 of the transistor and one end of the resistive region 32 are connected to ground by conductive tracks 44, 50 which terminate in contact with the isolation regions 36, 38 which, together with region 14, form conductive paths to a metal ground plane 12 on which the wafer is mounted. N<SP>+</SP> type regions 30, 34 may be provided beneath the transistor and the resistor by diffusing impurities into the substrate 18 before epitaxially depositing layer 20. These N<SP>+</SP> type regions decrease the collector saturation resistance of the transistor and prevent parasitic transistor actions. Tracks 44, 50 and other connections (not shown) to the base and collector regions of the transistor and to the second end of the resistor, extend over a silicon dioxide layer 40 provided on the surface of layer 20. It is mentioned that integrated circuits may contain other components such as unipolar transistors and capacitors. Resistors and capacitors may also be fabricated partially or completely on top of the insulating layer.

Abstract: A composition curable at room temperature to an elastomer comprises by weight (1) 100 parts of a siloxane of at least 100cs. viscosity at 25 DEG C., containing Si-bonded OH groups and being composed of units of the formula <FORM:0844128/IV(a)/1> , wherein each R is a monovalent hydrocarbon or halogenated hydrocarbon radical and in which the average value of n in the polymer is from 1,99 to 2,0 inclusive, (2) from 0,2 to 10 parts of a silicate of the formula R14-mSi(OCH2CH2OR11)m, in which each R1 is a monovalent hydrocarbon or halogenated hydrocarbon radical containing less than 7 C atoms, each R11 is a monovalent aliphatic hydrocarbon radical containing less than 6 C atoms and m is 3 or 4, or a partial hydrolysate thereof, and (3) from 0,01 to 10 parts of a catalyst which is a carboxylate of a metal ranging above H in the electromotive series of metals, and in which the acid radical contains less than 16 C atoms. The radicals in siloxane (1) may be alkyl, alkenyl, cycloaliphatic, aryl, aralkyl or alkaryl, and may be halogenated.  The silicate (2) may be diluted with conventional orthosilicates or polysilicates in amounts up to 50% by weight based on siloxane (1).  The catalysts, many examples of which are given, can be dispersed in the compositions by means of mutual solvents with siloxane or by dispersion on fillers and thereafter milled into the siloxane. Fillers, e.g. cork, wood, flour, cotton linters, CaCO3, TiO2, C black and SiO2 powders, oxidation inhibitors, compression set additives and pigments, may also be added.  If the compositions are to be stored prior to use, the carboxylate or the silicate must be stored separately. The compositions cure at room temperature, though, if desired, they may be press-cured at 150 DEG  to 250 DEG C.  In a typical Example (1) 100 pts. (by weight) of a liquid end-blocked dimethylpolysiloxane containing Si-OH groups was mixed with 30 parts of diatomaceous earth, 0,5 pt. of lead octoate and varying amounts of different silicates, the lead octoate being added as a mixture of 100 parts of a liquid hydroxyl-free dimethylpolysiloxane, 30 parts of diatomaceous earth, 2 parts of ferrous oxide and 31 parts of lead octoate.
