Filed: 1941-10-20
Abstract: 587,927.. Metal-to-glass seals. GENERAL ELECTRIC CO., Ltd., BREADNER, R. L., and WIGGINS, E. J. Oct. 20, 1941, No. 13480. [Class 36] In a machine for producing a multiple-wire bead-seal, such as that shown on the drawing accompanying the Provisional Specification, the wires are held spaced within the surrounding glass supported on a carrier which is intermittently vertically reciprocated to prevent falling-away of the molten glass, the latter being finally moulded in situ by dies movable into and out of operative position. As shown, a pair of wires, 9, 10 provided with glass beads 40, 41 at the seal location are passed through a glass sleeve 32 which is assembled between a pair of carriers 1, 2 for fusion by a gas-burner 26. The carriers 1, 2 constitute a half-die member which is completed by a pair of arms 18, 19 pivoted on the carriers. During the fusion stage, the lower carrier 2 is reciprocated by a power-operated cam 22. The carrier is then raised clear of the cam by means of a hand-lever 25 which is also linked to the upper carrier 1 whereby the carriers are closed on to the molten glass. In this movement, links 27 carrying the burner 26 are freed from a holding-catch 29 which is connected to the lever 25 by a cable 30 and link 33, the burner being automatically returned to its inoperative position (Fig. 1) by a spring 28. At the same time, the other die-members 18, 19 are closed to complete the mould.

Title: Process for producing aliphatic carboxylic a cid esters as solvents for paints, lacquers and varnishes
IPC: C07C69/24
Filed: 1965-03-30
Abstract: Aliphatic carboxylic acid esters are prepared from a mixture of acetaldehyde and a saturated aliphatic aldehyde (3-5 C) or a methoxy or ethoxy substitute thereof, or a mixture of the latter aldehydes, by a first step of condensation in the presence of an aluminium alcoholate catalyst; a second step of recovering by distillation the lower, middle and higher boiling fractions from the ester mixture; a third step of admixing the higher boiling fraction with at least part of the lower boiling fraction and catalyst raw materials comprising aluminium, lower saturated aliphatic alcohol and aluminium chloride, thus converting a portion of the higher boiling fraction to a middle boiling fraction and simultaneously producing an aluminium alcoholate catalyst.  In the third step the higher boiling fraction may contain residual aluminium alcoholate catalyst.  Process for the reaction of mixtures of acetaldehyde and n-butyraldehyde and/or isobutyraldehyde, propyl aldehyde, isoamyl aldehyde, methoxy butyraldehyde are described together with flow diagrams of apparatus used.  The mixed ester products are suitable for use as paint, varnish and lacquer solvents.

Abstract: 1478192 Automatic control of crystal growth NATIONALE RESEARCH DEVELOPMENT CORP 4 April 1975 [29 March 1974] 14167/74 Heading G3N Crystal growing apparatus includes a heated crucible containing a melt from which a crystal is pulled. The weight of the growing crystal is continouously sensed and compared with a reference function to produce an error signal for controlling the melt temperature. The phase of the error signal is advanced to compensate for thermal lag effects. As shown in Fig. 1, a crystal 9 is pulled from a melt 7 in a crucible 5 by a rod 1 suspended from a load cell 8. The rod is raised by a motor 13 and adjusts the output from a position transducer 25 to form a reference signal representing the weight of a crystal growing with a uniform cross-section. This signal is combined with the load cell output signal in a comparator 23 which forms an error signal used to control the power supplied to an RF heating coil 11, thereby adjusting the melt temperature. In order to compensate for thermal lag effects in the coil and the melt, the error signal is passed through a phase advance circuit 31 which has the effect of producing the desired temperature changes much more rapidly than would otherwise be the case. The circuit 31 may take the form of two operational amplifiers connected in series with parallel RC circuits as shown in Fig. 3. The phase advance may alternatively be produced by a digital circuit.
