Title: Method and apparatus for forming fibres from heat-softened glass or like mineral materials
IPC: C03B37/04
Filed: 1971-09-13
Abstract: 1328021 Glass fibre production OWENSCORNING FIBERGLAS CORP 13 Sept 1971 [14 Sept 1970] 42663/71 Heading C1M A hollow centrifuge spinner 78 comprises an imperforate bottom end section 100, 110 and a peripheral wall section 140 having a plurality of stream flow orifices 152 in the peripheral wall, the passages adjacent the top end of the wall having greater flow resistance than the passages at the bottom end of the wall. The variation in flow resistances is preferably achieved by employing a wall 140 of varying thickness with the thickest portion at the top end so that the passages 152 at the top end have a greater length than those at the bottom end. The bottom section has an upwardly inclined portion 110 adjacent the wall 140 which in turn has an inwardly directed flange 112 at its top end. An annular combustion burner is provided adjacent the spinner with an annular throat 70 which discharges hot gases into a heat transferring relationship with the wall. The flange 112 is shielded from the hot gases by a cooled baffle 156. The spinner is also surrounded by a blower construction 122 which provides an attenuating blast through outlet 130 and induced air through passage 142. In use a stream of molten glass 18 is delivered on to the inclined portion 110 and the spinner is rotated by means of a vertical shaft (84) thus driving the glass towards the wall 40. As a result of the impingement of hot burner gases on the wall 140, the glass at the top end of the wall is at a higher temperature than that at the bottom end. This is compensated for by the greater flow resistance of the top passages thus enabling the production of fibres of uniform diameter.

Abstract: 1,059,540. Time switches. MALLORY BATTERIES Ltd. Oct. 8, 1965 [Nov. 12, 1964], No. 42728/65. Heading H2B. [Also in Division F2] An intermittently rotatable timing cam 28 has a plurality of concentric cam grooves 29 for actuating follower switches (30) (Figs. 2, 4, 5, not shown). Riding in the grooves are pins (49) of switches (30) which are displaced by jog segments 54 to pivot contact-carrying blades (39) to close contacts (40), (38) or (41), (38) or to open them (Fig. 5, not shown). The drive 11 for the sequential timer 10 rotates a gear 15 and a drive cam 18, coupled by a hub (17) to form the cam assembly 52, incorporated in an escapement 19. The rotation of cam 18 is converted into stepping movement of a ratchet wheel 25 on the shaft (26) of cam 28 via displacement of a follower arm 21 and a rigid arm 24 pivoted thereon, stressing a spring 22 to provide the force to displace wheel 25. Overdisplacement of wheel 25 beyond one tooth increment is prevented by a floating partial cam 31 carrying a pin 32 movable in a slot 33 of the drive cam 18. The return movement of follower arm 21 is delayed by an air piston 34 (Fig. 6, not shown). A knob (35) selects a desired sequence or passes over unwanted sequences of operations.

Title: Preparation of 2,6-dimethyl-2,7-octadiene
IPC: C07C5/31
Filed: 1962-11-13
Abstract: 2,6 - Dimethyl - 2,7 - octadiene is prepared by thermally isomerizing pinane, e.g. at 400-700 DEG  C., in which the pinane cis-isomer predominates over the trans-isomer, and recovering the required diene from the resultant mixture. The yield of #i-2,6-dimethyl-2,7-octadiene may be increased by isomerizing pinane in which the #i-form predominates over the d-form and the amount of #i-cis-pinane is at least equal to the amount of #i-trans-pinane, stopping the isomerization before all the pinane is converted and recovering the required diene.  The pinane may be prepared by hydrogenating #i-b -pinane with either a Raney or Rufert nickel catalyst. U.S.A.  Specifications 2,388,084 and 2,902,495 are referred to.

Abstract: 940,590. Fluid-blast switches; fusible cutouts. E. LANGE, and NATIONAL INDUSTRI A. S. Nov. 30, 1961, No. 42873/61. Headings H2B and H2G. On separation of the contacts 2, 4 of a switch, an arc is drawn in a chamber 1 containing a gas or liquid, the arc transferring to electrodes 6, 7. The latter is formed as a choke element partially obstructing the outlet from chamber 1, and it contains a spring-loaded valve 11 which opens due to the pressure produced in the chamber 1. A continuation 9 of the element 7 has cam surfaces 14, 16 co-operating with spring catches 17 ... 20 which normally prevent the element 7 from retracting beyond the Fig. 2 position. However, when breaking large currents, the consequent high pressure overcomes the catches and the element 7 is suddenly moved to the Fig. 3 position. Fusible cut-outs.-In another form, upon melting of a fuse wire 41 a single long arc struck between end retainers 38, 39 divides into three portions between retainer 38 and an electrode 32, between electrode 32 and a second electrode 33, and between electrode 33 and retainer 39. The fuse casing contains a fluid quenching medium, and the pressure produced therein by the arc causes arc quenching in insulating choke elements 34, 35 carried by the retainers 38, 39. If the current is greatly excessive, the pressure is sufficient to rupture one or both of the retainers 38, 39, the associated choke element being expelled to free one or both of the outlet passages 27, 28 in which the arc is quenched.

Abstract: 1324865 Solid/liquid contact apparatus COMMISSARIAT A L'ENERGIE ATOMIQUE 8 Sept 1970 [17 Sept 1969] 42923/70 Heading B1F [Also in Division C2] A process for preparing an alcoholate by dissolving under controlled conditions sodium, potassium and/or an alloy thereof after irradiation thereof by a radioactive source comprises dissolving under an argon atmosphere the irradiated metal and/or alloy in a mixture of an alcohol and a liquid which is completely miscible with the alcohol and which does not react with the irradiated metal and/or alloy, and controlling the dissolution reaction by adding one or more further quantities of the alcohol and/or the liquid. The said liquid may be a kerosene based machining fluid. In the apparatus shown, irradiated metal and/or alloy is flushed from capsule 35 by the said liquid from 37 into tank I which already contains a quantity of the said liquid, through which argon is passing from conduit 25. A mixture of alcohol and liquid is then passed through the capsule into tank 1 and dissolution begins. A thermometer probe is inserted in the most suitable glove box temperature measuring points 11, and if the dissolution temperature exceeds 150‹C, the argon flow from conduit 29 is increased and a quantity of pure liquid is injected. If the temperature falls below 100‹C, alcohol slightly diluted with liquid, then pure alcohol, is injected. The flow of argon from conduit 25 provides agitation.

IPC: G01N23/223
Filed: 1964-10-23
Abstract: 1,081,683. X-ray analysis. FARBENFABRIKEN BAYER A. G. Oct. 23, 1964 [Oct. 26, 1963 (3)], No.43374/64. Heading G1A. The qualitative and quantitative analysis of the components, of a mixture of at least two crystalline substances is carried out by directing X-rays at the sample and measuring with separate pulse counters that diffracted X-radiation from the sample which is associated with each substance. The apparatus can be used in the Bragg-Brentano arrangement when the sample takes the form of either a mosaic crystal block or powdered crystals pressed into a rectangular container, or in the Debye arrangement, when a powdered sample in the form of a rod is used. In a first embodiment (Fig. 1) the X-rays from a tube 1 pass through an anti-divergence and anti-halo shutter 2 to the sample 3 and are diffracted in two (or more) beams (according to the number of different crystalline substances in the sample) towards a filter 4 (for suppressing K# radiation), and entrance and scatter shutters 5 and 6 into detectors 7a, 7b which may be geiger tubes. Signals from the latter pass through separate channels, each comprising an amplifier 8 pulse-shaper 9 and counter 10, for each substance in the sample. The ratio of counts is found in a comparison instrument 11. If a standard material is used in the sample, the counting channel with which it is associated can be stopped measuring when a predetermined count has been registered, the counts registered by other channels, corresponding to the other components of the sample, being printed out by a device 12. In a second embodiment Figs. 3 and 4 (not shown) the detectors 7 are substituted by radiation converters (7), light guides (14) leading to an optical reversing switch (15) passing one radiation path at a time to an electron multiplier (16). Resultant signals then pass through a common amplifier (17) and pulse-shaper (18) and are selectively passed to their appropriate counters (20) to pass on to common comparison and printing instruments (21, 22). In a third embodiment Figs. 6, 7 (not shown) a common Geiger counter (16) is used and the light-path selector takes the form of a rotating disc shutter (15) coupled to a photoelectric system (30, 31) to control selection of the counters (20). In a further arrangement Fig. 5 (not shown) using the Seemann-Bohlin principle for X-ray cameras, the surface of the sample is two-or-three dimensionally curved to focus the different radiation beams corresponding to each constituent on to different detectors.

Abstract: 1,122,327. Control of D.C. motors. POTTER INSTRUMENT CO Inc. 30 Sept., 1966 [20 Oct., 1965], No. 43762/66. Heading H2J. [Also in Division G3] In a magnetic tape storage system having a vacuum storage bin for a single loop of tape on either side of the processing head, each bin has upper and lower limit detectors which control a D.C. motor on the nearest reel so that it rotates one way or the other, or is dynamically braked, according to whether the loop is above, below or between the detectors. The detectors comprise lamps and photocells whose resistance drops when illuminated. As shown, the photocells 33, 37 control a transistor circuit and the arrangement is such that when both are illuminated the motor armature 94 is energized from negative terminal 59 via transistor 91, the circuit being completed to earth through diode 95 and transistor 81 (transistor 89 is cut off); when neither are illuminated the armature current is reversed, the current path now including transistors 89 and 86, and diode 97. The conducting transistor is back biased by the back e.m.f. and thus the speed is controlled. When one cell is illuminated and the other isn't the back e.m.f. biases either 89 or 91 on, which acts as an emitter follower to effectively clamp the relevant side of the armature to ground, thus short circuiting it; reversal is prevented because when back e.m.f. reaches zero both 89 and 91 are cut off. The motor may be separately excited, or, in Fig. 3 (not shown) as series field is connected to terminal 59. In alternative circuits (Figs. 4 and 5, not shown) transistors 89 and 91 are replaced by thyristors, the D.C. supply being pulsating, and braking is by reverse current from the source.
