Abstract: 1,051,356. Fluid pressure servomotor systems. C. PASQUALE and A. PASQUALE, [trading as R. C. M. RIVISIONE CONSTRUZIONE MACCHINES]. Oct.7, 1963 [Nov.17, 1962], No. 39455/63. Heading G3P. [Also in Division D2] Level control means for the vat of a cylindertype paper-making machine (see Division D2) comprises a diaphragm 52 installed in the side wall of the vat and sensitive to the hydrostatic pressure of slurry contained in the vat. The diaphragm 52 controls the position of a spring- loaded piston valve 34 which in turn controls the flow of oil through a port in the cylinder 29 in which the piston valve is mounted and thereby regulates the pressure in one end 39b of a further cylinder 39. An oil pump 45 supplies oil via the end 39b of cylinder 39 to the cylinder 29 and is also connected to the closed end 39a of the cylinder. Piston 40 mounted in the cylinder 39 controls valves 25 and thereby regulates the supply of slurry to the vat to maintain a constant level therein.

Abstract: 1,052,572. Electric motors. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 12, 1965 [April 30, 1964], No. 15381/65. Heading H2A. [Also in Division G5] A stepping motor for driving a magnetic tape in incremental steps past a transducing head (see Division G5) includes a ten-teeth rotor 36 which is normally held in position by flux from the permanent magnets 41, 42 passing through the detent member 43, the rotor and the arms 39, 40. When a pulse is applied to the winding 37 in such a direction as to neutralize the flux in the arm 39, the rotor 36 steps through 1/20 revolution so that the teeth 45 and 46 come into closer proximity with the projections 47, 48 on the arm 40. If the winding 37 is then pulsed in the opposite direction, the rotor again steps 1/20 revolution clockwise. Rotor oscillation is damped by an air vane arrangement.

Abstract: 1,226,735. Glass tempering die. FORD MOTOR CO. Ltd. 30 Sept., 1969 [21 Nov., 1968], No. 47931/69. Heading C1M. A die for a glass tempering apparatus comprises a rigid supporting platen, a layer of deformable elastomeric material (such as silicon rubber) containing a powdered metal (such as copper), and glass cloth fabric covering the surface of the material, which fabric is in use brought into contact with the glass during the tempering operation. The elastomeric material preferably has from 10% to 70% by volume of copper powder, the copper particles being from 4 to 10 microns in diameter. The heat may be extracted from a glass sheet during tempering at different rates in different areas either by varying the thickness of the glass fabric or the metal powder content of the elastomeric material. To produce curved glass, the glass may be tempered between two dies, one having a greater thickness of glass cloth, thus decreasing one die's capability to extract heat and thus causing the glass to bow after removal of the dies. Alternatively the glass may be curved by using a matched pair of curved dies whereby an initially flat glass sheet is bent into a curved shape. .

Abstract: 1,238,151. Orienting semi-conductor chips; transferring semi-conductors and their carriers between endless conveyers. INTERNATIONAL BUSINESS MACHINES CORP. 5 Feb., 1970 [7 March, 1969], No. 5555/70. Headings B8A and B8S. [Also in Division H1] So that a semi-conductor chip 100, Fig. 1, can be correctly oriented and placed in a substrate 102, the two are scanned by an optical system 199, and, from the information regarding the misalignment, electrical signals are produced which are used to correctly position the chip with respect to the substrate. In the optical system, a lens 108 projects an image of the chip via a beam splitter 109, a prism system 110 and a rotating mirror 111, on to an aperture in a mask 113, where a photocell monitors the light intensity. Another image of the chip passes from the beam splitter to a rotating mirror 115 and slits in a mask 116 where it is monitored by photo-cells 117, 118. The outputs from these photo-cells and those in a similar system for scanning the substrate are fed to a measurement and correction logic 119, a block diagram of which is illustrated in Fig. 3 (not shown). Fig. 2A shows an optical system in which beam splitters 204, 205 pass beams to four-sided mirrors 208, 209 and then to photo-cells 214-219. Fig. 2B shows an arrangement in which a sub-assembly, Fig. 2C, is used. In Fig. 2B a compound beam 230, Fig. 2C, from both the chip and substrate is passed through a beam-splitter 225, Fig. 2B, to rotating mirrors 226, 227 and photo-cells X1, X2, Y. Electrical signals from the measurement and correction logic 119, Fig. 1, are fed to a placement table 198, the position of which is adjusted in accordance with the correction signals by power-driven screws 152, 153, 154. The movable part of the table carries a suction pick-up device 145 which picks up the chip after it has been moved over orifice 144 and, after orienting it, deposits it through orifice 144 into the substrate which has been moved below orifice 144. The chip, on a carrier 101, is moved from the chip measurement station to the placement station by endless belt conveyers 135, 138 driven by motors 136, 139. To release the chip from the measurement station a notch 105, which engages a locating pin 104 on the chip carrier, is withdrawn by a solenoid 133, and the chip and carrier are pushed from conveyer 158 to conveyer 135 by a solenoid 136. Transfer between conveyers 135 and 138 is effected by a solenoid 137. The substrate 102 is moved along by a conveyer 143 in a similar fashion.

A woven gauze fabric comprises weft retention means in the form of yarns 3 in the warp direotion each of which is adhesively attached at 4 to at least a majority of weft yarns 2 along its length, the spacing of such adhesively attached yarns 3 being greater than the spacing of the warp yarns 1 in the woven fabric. The yarns 3 may be warp yarns, Fig. 1, or yarns additional to the warp yarns 1 and laid onto the gauze after it has been woven. Preferably, the yarns 3 are each adhesively attached to every weft yarn 2. The yarns 3 may be made of or coated with a thermoplastic or heatsoftenable material and may be adhered to the yarns 2 by heating, e.g. by passing the fabric under tension around a heated drum and/or by light calendering. Specified yarns 3 contain staple fibres, multi-filaments, monofilaments or split film monofilaments of polyvinyl chloride polyvinylidene chloride, polyethylene, polypropylene, polyamide, cellulose diacetate, cellulose triacetate, polyacrylonitrile, a polyamide yarn coated with a polyolefin, or yarns coated with a material based upon cellulose-acetate-butyrate or ethylene-vinyl acetate copolymers, polyvinyl acetate, acrylics or styrene-butadiene rubbers. The gauze fabric may be woven from natural or man-made yarns, e.g. cotton, rayon or polyamide. If the yarns 3 are superimposed upon a prewoven fabric, they may be passed through a liquid adhesive, such as an organosol, e.g. polybutyl methacrylate dissolved in xylene, a plastisol, e.g. polyvinyl chloride dispersed in dibutyl phthalate plasticizer, or a water-based adhesive, e.g. polyvinyl alcohol or an acrylic emulsion, before being applied to the fabric. Adhesion may be accomplished by passing the fabric with the yarns superimposed thereon around a heated drum or by dielectric heating. Alternatively, superimposed yarns 3 may be made of a solvent softenable thermoplastic material which is treated with a softening solvent before or after superimposition, e.g. in a spaced stripe configuration. Polyacrylonitrile staple fibre yarn may be softened with cyclotetramethylene sulphone and cellulose acetate with dimethyl glyophthalate.
