Abstract: 934,977. Upsetting. FORD MOTOR CO. Ltd. July 19, 1962 [Sept. 7, 1961], No. 27748/62. Class 83 (4). An elongated article, particularly a steel bar 11, is upset by heating a first portion 26 imping- ing a cooling fluid upon the heated surface, applying axial pressure whilst supporting the article radially by means 21 to upset the heated first portion, and repeating the process upon a second portion adjacent the first portion to upset the second portion into a continuous mass with the first portion. The bar 11 is held in a rotatable clamp 14 and during upsetting is rotated by a chuck 15 which also applies the axial pressure. Heating to 1800-2000 F. is effected by an induction coil 23 supplied by a high-frequency power source 25, and cooling air from a source 29 is supplied to a ring 24 and discharges through orifices 27. The ring 27, inductor 23 and guide means 21 are mounted on a slide 20 movable along rods 18 by a lead screw 32 whereby the slide is driven manually or automatically along the bar whilst the axial pressure is maintained by chuck 15. In another embodiment, Fig. 3 (not shown), the inductor is a tubular coil which also receives the cooling air and has discharge orifices on its interior surface. The coil also may be double-walled to permit circulation of cooling water between the walls.

Title: Apparatus for intermixing liquids
IPC: G05D11/00
Filed: 1976-07-08
Abstract: The water coming from the public tap-water system flows through the inflow pipe (3) having the valve (5) and the water motor (11). The water motor (11) drives the metering piston pump (10) which itself conveys the additive, for example a disinfectant, out of the tank (9) into the storage tank (2) virtually without any counterpressure. The centrifugal pump (6) extracts the liquid mixture from the storage tank (2) and forces it by way of the non-return valve (12) and the shut-off valve (15) to the consumer. The pressure vessel (7) serves for compensating pressure surges and pressure fluctuations in the main pipeline (1). When a predetermined level is reached in the storage tank (2), the solenoid valve (5) is cut off, so that the tap-water inflow ceases. The drive of the metering pump by the water motor allows an exact metering of the additive. <IMAGE>

Filed: 1965-07-05
Abstract: 1,115,336. Control of A.C. motors. COMPAGNIE ELECTRO-MECHANIQUE. 5 July, 1965 [8 July, 1964], No. 28415/65. Heading H2J. [Also in Divisions F4 and G1] The starting winding 1b of a shaded pole single-phase motor 1 driving the fuel supply equipment of a burner (not shown) is in serieswith a delay tripping element 5 of a cut-out and with either contacts 2a which are opened by the action of a photo-conductive cell 3 detecting the flame of the burner or a parallel arrangement of a capacitor (11) and the photoconductive cell, Fig. 3 (not shown). When a thermostat 6 closes its contacts a relay 2 is energized and closes contacts 2a, 2b to start the motor and energize an ignition transformer 8 and open contacts 2c to take the photo-cell 3 out of circuit. After a predetermined time the tripping element 5 of the cut-out closes contacts 5b to connect the photo-cell across the relay 2 and if the burner has ignited the reduced resistance of the cell de-energizes the relay 2 so that the contacts 2a, 2b open to de-energize the starting winding and the ignition transformer and the contacts 2c close to keep the cell in circuit. The contacts 5b may be replaced by a thermistor. In a simplified circuit, Fig. 1 (not shown), the contacts 5b and 2c are omitted. In the circuit of Fig. 3 (not shown), the capacitor (11) has the same impedance as the starting winding (1b) of the motor and therefore the current in the starting winding is limited only by its resistance and by the resistance of the element (5) of the cut-out. In the presence of a burner flame, however, the photo-cell (3) short circuits the capacitor and the current in the starting winding drops.

Filed: 1936-10-19
Abstract: 483,567. Feeding sheets. HORGAN, G. D., and INDUSTRIAL MACHINERY CO., Ltd. Oct. 19, 1936, No. 28437. [Class 100 (i)] A machine for feeding sheets from a stack, which is especially applicable for feeding picture cards or coupons to cigarette packets, is constructed to facilitate the separation of the cards from the stack by arranging the device so that a substantially constant pressure is exerted by the leading card on the separating mechanism, moving surfaces of a yielding nature, such as bristles, being adapted to engage the sides of the stack of cards and urge them towards the separating means. The cards are stacked in a magazine formed of a base plate 5, adjustable side walls 6, guide strip 7, and an end wall 8 to form a stack arranged at an angle approaching the vertical. The end wall 8 is stopped short of the lower edge 9 of the base plate 5 to provide a delivery opening, and the lower' end of the base plate is formed angular in cross section and is curved transversely to form a central crest, as shown in Fig. 1a, and this co-operates with a similar but reversed crest on an adjustable gate 10. The gate 10 is controlled by a screw stop 11 held to the wall 8 by a spring plate 12. The cards are pressed towards a separating roller 13 fitted with spaced segmental friction surfaces 13a by means of a pair of rotating brushes 15, 16 which act through slots in the sides 6 of the magazine, and are driven by worm gearing from a main driving gear 26. The brushes are adjustably mounted and rotate in opposite directions, and the mounting 21 for the brushes is pivoted about an axis concentric to the shaft 38 of the gear 26 and so the unit can be set by means of a screw 40 for correct delivery of the cards 41 into the slide 34. This is effected by means of bands 31 passing over an adjustable grooved table 33. For inspection purposes the feed unit can be pivoted clockwise about the shaft 28 and held in inoperative position by means of a pivoted catch 42 and a pin 43. The invention may be applied to cigarette packeting machines of the kind described in Specification 479,130, [Group XVII], in which case two adjacent machines are geared together by providing a bevel wheel on the shaft 38 which gears with a similar wheel on the corresponding shaft of the duplicate unit. According to the Provisional Specification, the brushes may be replaced by endless bands or rollers with a pile surface, and these may be driven continuously or intermittently. The cards may be stacked on edge and advanced by spring or weight means.

Title: Purifying acrylonitrile by extractive distillation
Filed: 1952-11-12
Abstract: Acrylonitrile is purified from acetonitrile by submitting the crude acrylonitrile to extractive distillation employing water as extractant and maintaining a very high concentration of water in the liquid phase in the distillation column, whereby purified acrylonitrile vapours leave the head of the column together with water vapours.  The overhead vapours are condensed, and the condensate is allowed to separate into two liquid layers; the aqueous layer is returned to the column as reflux, and the acrylonitrile layer is submitted to further distillation to remove water.  In an example, 404 parts per minute of a vapour mixture containing acrylonitrile (94 per cent.), acetonitrile (3 per cent.) and water (3 per cent.), are fed to the second tray from the base of a 30-tray perforated plate column, while 1,600 parts per minute of water at 70 DEG -80 DEG C. are fed to the second tray from the top of the column. The temperature of the column-reboiler is maintained at about 85 DEG C.; and the liquid-temperature in the column below the water feed point is maintained at about 71 DEG C. The upper layer of the distillate contains acrylonitrile (95.5 per cent.), water (3.5 per cent.), and less than 1 per cent. of acetonitrile.  The base product, withdrawn from the reboiler at the rate of 1,659 parts per minute contains water (96.6 per cent.), acetonitrile (0.4 per cent.), and acrylonitrile (2.3 per cent.)  This product is distilled in a conventional column to recover a distillate containing the acrylonitrile, which is recycled to the extractive distillation.
