Title: Control of electrosmelting
IPC: H02P5/50
Filed: 1972-03-28
Abstract: 1389683 Automatic control of electro-smelting CHUVASHSKY GOSUDARSTVENNY UNIVERSITET IMENI IN ULYANOVA 28 March 1972 14359/72 Heading G3R In a method of controlling an electro-slag smelter having a consumable electrode 4 and a non-consumable electrode 9, an electrical parameter of the electrode 9 is measured by sensor 17 and compared with a pre-set reference from a source 18 in a comparator 19, a resultant error signal being used to modify the action of a rate  co-ordination unit 13, which receives signals from sensors 11, 12 of the feed rates of the electrodes 4, 9, by weighting one of these signals so that the ratio of the feed rates is adjusted to restore the electrical parameter to the reference value. As shown the unit 13 controls a drive 15 to displace the electrode 9. The electrical parameter may be the voltage of the electrode 9 with respect to the electrode 4 or metal ingot 8, or the current through electrode 9 if it is connected to the supply 6. The unit 13 comprises a magnetic amplifier 27, Fig. 2, the control windings 25, 26 of which are connected to tachogenerators 21, 22 measuring electrode feed rates. The control windings receive a current which depends on the ratio of the feed rates and the settings of a potentiometer 23 and rheostat 24. Bias windings 43, 44 are used to ensure zero output in main windings 32, 33 in the absence of a signal in control windings 25, 26. An increasing signal in the control windings causes progressively earlier switching on of transistors 30, 31 to supply rectangular triggering pulses to thyristors 28, 29. These control the armature current of a motor 50 in the drive 15 of electrode 9. The comparator 19 comprises another magnetic amplifier 64, Fig. 3 (not shown) the control winding (63) of which receives the parameter signal from 17 and the bias windings (65, 66) of which receive the reference signal from 18. The main windings (73, 74) control the triggering of thyristors (75, 76) in the drive circuit of a motor (87) which adjusts the slider of the rheostat 24 in the unit 13.

Abstract: 1445325 Supporting tools during heattreatment STEYR DAIMLER-PUCH AG 8 April 1975 [9 April 1974] 14374/75 Heading C7N A number of rod-like workpieces, particularly twist drills are grouped together for heat-treatment by inserting their ends into a bed of resin-bonded moulding sand which is then hardened to form a holder. Preferably the drills are inserted into the bed through a perforated plate which subsequently serves as a carrier. When treatment is complete the holder is destroyed by jolting. As particularly described a bed of sand 9 is formed in a moulding flask 1, while spaced from the latter is a charging plate 3 having countersunk perforations 6 and magnets 4 by which a flanged 8 carrier plate 7 is temporarily secured to it. Drills 10 are passed through the corresponding holes in plates 3 and 3 and embedded in bed 9. When the assembly is complete the carrier-plate is forced down into the bed. If necessary the sand bed is jolted and is then heat hardened, the tube 12 having been replaced by a flanged carrier rod 14.

[Also in Division D1] Tobacco smoke filters are prepared from a continuous film of polymeric material having a high degree of molecular orientation, by feeding the film through a jet to which a gas stream is supplied thereby effecting vibration of the film to effect a multiplicity of discontinuous slits along substantially parallel longitudinal lines to obtain a plurality of coarse filamentarylike ribbons which are fractured to produce integral hair-like protrusions extending transversely and multi-directionally therefrom, gathering the ribbon mass into a substantially cylindrical form and forming the mass into a tobacco smoke filter. The fractured ribbons are at least 10 microns thick and 10-90 microns wide, the hairlike protrusions being 2-10 microns thick and the proportion of protrusions in the finished filter being 10% by weight thereof. The ribbons may be bonded to each other at random points of contact by surface solvation bonds from the action of a plasticizer or by the application of a polyethylene binder powder and heat sufficient to fuse said powder. The polymeric material is preferably crystalline polypropylene. A blend of polypropylene and polystyrene, crystalline polyethylenes and crystalline polyallomers may also be used. The film may be coated with activated charcoal. Quantitative examples are given.

Abstract: 774,246. Lubricating. GENERAL MOTORS CORPORATION. May 20, 1955 [June 7, 1954], No. 14613/55. Class 12 (3). [Also in Group XXVIII] A method of applying liquid lubricant to a precision bearing from a column of lubricant in a tube having a calibrated discharge orifice at one end, comprises subjecting the other end of the tube to atmospheric pressure, and subjecting the discharge orifice in the region of the bearing to a substantially constant vacuum for an accurately timed interval. The apparatus may comprise a fixed member 10 connected by a conduit 15 to a lubricant supply tank 16 and by a conduit 12 to a tank 14 kept at a substantially constant vacuum, and a pivotally mounted member 50 provided with a handle 52 whereby it may be moved into abutment with the member 10 to enable lubricant to be supplied to the bearing, for example, a clock jewel 60, carried by the member 50. The conduit 12 has a valve 13 which may be opened by a solenoid or other device for accurately timed intervals to apply suction to a passage 11 leading to an opening 41 in a housing 40 in member 10. The housing carries a spring-pressed sleeve 35 and a plug 44 through which extends a hypodermic needle 31 communicating with the conduit 15. The member 50 is recessed to receive the jewel 60. When the member 50 is moved against the member 10, the jewel 60 engages a seal 47 and also moves the sleeve 35 upwardly. On the opening of the valve 13 for a timed interval suction acts through the lateral opening 41, around sleeve 35, and around the hemispherical top thereof to cause lubricant to flow down the needle to the jewel 60.

Abstract: 1,129,934. Switches held set and freed mechanically. J. L. OTTERLEI. 30 March, 1967, No. 14674/67. Heading H1N. In a switch assembly 10 having push-button switches 11, 12, 13, 14 and associated motoroperated cams 60a, 6Ob, 60c, 60d connected in a manner so that when a push-button 21 is depressed the associated cam releases the button after a predetermined period of time, each pushbutton has a rod 51 attached for axial movement therewith and pivotal transverse movement by the associated cam to move a release bar 30 via a shoulder 33 thereon such that the push-button is released. Each cam 60 is adjustable via an externally accessible opening (76) in a worm gear 75 engaged with a pinion gear 72 when the two disc-shaped members 61, 70, of the cam 60 are assembled (Figs. 4, 5, not shown). Cam surface 71 engages rod 51 of each push-button to provide the transverse movement. Cams 60a, 60b, 60c, 60d, 60e are attached together and driven by a motor 56 via gearing 57 and shaft 58, the motor being energized, when a push-button is depressed, to drive the cams for the associated cam to release the pushbutton and de-energize the motor, the cams being restored to their initial position by a coil spring 78. Each cam may give a predetermined time delay before the push-button is released. As a safety precaution cam 60d always engages rod 51 of switch 14, even when the pushbutton is not depressed. Button 21 has a slide 22 carrying a contact carriage 23 with contacts 39 for engaging any two adjacent fixed contacts 38 of the three rows of contact lugs 38, depending on whether the button is depressed or not. Slide 22 has a tooth-shaped member 35 by which it is latched by a shoulder 32 on bar 30 engaging behind it. If a second push-button is depressed its member 35 cams bar 30 sideways, to release slide 22 of the first latched push-button, and then the second push-button is latched. Alternatively, a second push-button cannot be depressed until the first push-button is released by its associated cam. No two push-buttons can be depressed simultaneously (see also Fig. 14, not shown).

Light is emitted through the substrate side by removing the light absorbing substrate 3, graded layer 2 and part of layer 1 either over the entire area of the device or in the regions of the junctions. The device is thenmounted on a substrate with the contacts adjacent one face thereof using solder ball connections described in Specification 1143,815. or by adding solder to the contacts and using a substrate with an appropriate lead pattern. In this arrangement edge emission increases the diode effective light emitting area and the use of 'incompatable' substrates, e.g. of Si containing integrated drive circuitry is possible.
