Abstract: 1,258,136. Cutting sheet glass. P.P.G. INDUSTRIES Inc. 19 Feb., 1969 [28 Feb., 1968], No. 8876/69. Heading C1M. A glass sheet is cut by providing a thermal energy source adjacent to, but spaced from, an intended line of cut, positioning a reflector to focus radiation from the said source on to the glass, and activating the source so as to introduce temporary thermal stress in the sheet until the sheet fractures along the line of energy application. The thermal source may be an electrical heating element, maser, lamp or flame. A moving glass sheet may be cut transversely or longitudinally. Preferably an edge nick is introduced in the intended line of cut. To aid fracture, a bending moment may be applied about said line as by passing between rolls or a cold platen on the opposite side from the heat source may be applied. A portion of a first glass sheet cut by the method in question may be used as a template in cutting a second sheet. The thermal energy source may be a line heater.

Abstract: 1295741 Toothed gearing R HARTWIG 3 March 1970 [4 March 1969] 10193/70 Heading F2Q [Also in Divisions G3 and H1] A time measuring device such as a clock or time switch comprises first and second discs 29, 17 which are independently rotatable about a common axis 12 and provided with peripheral teeth 31, 18, respectively; the root diameter of the teeth 31 being greater than the outer diameter of the teeth 18 so that a tangential driving pawl (38, Figs. 7, 10, not shown) which engages successive teeth 31 to advance the disc 29 is prevented from engaging the teeth 18 except when the pawl enters a deeper tooth notch 32, whereupon the pawl engages both the discs 29, 17 and advances them together by one step. Fig. 1 shows a clock in which the seconds, minutes, and hours are indicated by strips 41, 28, (46, Fig. 6, not shown), on discs 29, 17, 44 respectively, which are moulded of transparent plastics. The seconds disc 29 is rotatably mounted on a hub 22 on the disc 17, the hours disc 44 being similarly mounted on a further hub 24 which lies on an axis 26 eccentric with respect to the axis 12. The assembly of the three discs is mounted in a casing 11, 51 by means of a pin 54 which projects from rear wall 52 of the casing part 51 concentrically with the axis 12 and which engages a blind hole 56 in a hollow knob 21 on the disc 17. The knob 21 projects through the transparent front part 11 to permit setting of the minutes and hours discs 17, 44. The front 11 carries dial markings (14, Fig. 3, not shown).  The minutes disc 17 drives the hours disc 44 through reduction gearing which comprises an annular portion 47 on the disc 44 which has twelve internal teeth 48, Fig. 2, and is coaxial with the axis 26. The twelve internal teeth 48 co-operate with eleven external teeth 58 on a wheel 57 which is moulded within a recess 59 on the casing part 51. This gives a reduction ratio between the discs 17, 44 of 12 : 1 but another embodiment is envisaged which is a twenty-four hour, hundred minute, and hundred second clock. The driving pawl (38) is reciprocated by a synchronous motor, through reduction gearing contained in the base (88, Fig. 8, not shown) of the clock, at one cycle per second. For use as a time switch the time indicating strips 41, 28, (46) are omitted and electrical contacts are fixed to the discs 29, 17, 44 so as to co-operate with stationary contacts on the case. The switched circuit may use contacts on two or more of the discs.

Abstract: 1295792 Production of zearalenone by fermentation COMMERCIAL SOLVENTS CORP 19 April 1971 [18 June 1970] 23364/71 Heading C2C Zearalenone is obtained by cultivating a submergible, aerobic, zearalenone-producing strain of the micro organism Gibberella zeae in a fermentation zone while submerged in an agitated, aerated, aqueous, liquid phase fermentation medium containing assimilable carbon, nitrogen and mineral sources to yield a spent fermentation medium containing recoverable zearalenone, which process comprises replacing a portion of the spent, zearalenone-containing medium with fresh fermentation medium containing assimilable carbon, nitrogen and mineral sources, whereby the unreplaced spent medium serves as inoculum for the replacement medium. Specified micro organisms are Gibberella zeae (Schw.) Petch strain 542 Keith ATCC 20273 and Gibberella zeae (Schw.) Petch strain Paul S. ATCC 20271. The fermentation medium is suitably maintained at 20-28 C. and preferred carbon and nitrogen sources are glucose and urea respectively. The fermentation medium also preferably contains yeast extract, a foam inhibitor, a growth promoting amount of a hydrolysate of protein and an osmotic pressure-enhancing salt. The initial fermentation medium (e.g. containing 20 to 40 g. glucose per 100 c.c. of medium) may be retained in the fermentation zone substantially without replacement until the glucose concentration therein declines to 3 g. or less per 100 c.c. of medium, when at least one partial replacement of spent fermentation medium is suitably effected by removing 5 to 80 volume per cent thereof and adding replacement medium to the fermentation zone in an amount sufficient to provide a concentration of from 1 to 20 g. glucose per 100 c.c. of medium. The partial replacements may be continued while the zearalenone concentration in the spent medium is at least 10 micrograms per ml. of medium.

Abstract: 1295878 Tubular polyamide films WOLFF WALSRODE AG 23 Dec 1969 [23 Dec 1968] 62532/69 Heading B5B  Deep drawable tubular polyamide films with a balanced surface stretching ratio are made by a process comprising, homogenizing the pressure and temperature of a polyamide melt in a circular slot die; extruding the melt from the die at a temperature of at least 20 C. above its crystalline melting point; simultaneously cooling, shaping and stretching the extruded melt by an external gas stream in circular form, which flows in the direction of movement of the film between the film and a cooling ring and a cooling device with frusto-conical surface, while stretching the film longitudinally by means of the draw off device and transversely by a volume of gas enclosed in the tube, the stretching in the direction of movement of the tube in the transverse direction being substantially equal to each other; flattening and drawing off the film by means of a flattening device and at least one pair of squeeze rollers, the polyamide having the characteristics defined by the shaded regions of Figs. 3 and 4 (not shown). As shown, the polyamide melt is extruded from the annular gap 5 forming a tubular film 8, 8a, and cooling air flows from the cooling ring 6 through die system 15 along the direction of movement of the film through die systems 16 and 17 arranged one above the other so that the inner walls of these are formed by the film 8, 8a, and the external walls by the upper part of cooling ring 6, and the upper part of cooling device 14 respectively. The longitudinal stretching of the film is carried out by the draw-off rollers 10, 10a at draw ratio between 6-15 m./min. While solidifying, the melt flows through the first die system 15 where its expansion, determined by the temperature and pressure of the inflating gas, is reduced by the cooling gas; the second die system 16 where its expansion is increased by the cooling gas; and the third die system 17 where the film is stabilized after termination of its expansion. The tube is then flattened by flattening device 9 and drawn off by rollers 10, 10a; cut open and delivered to winders 11 and 12. The use of nylon-6 and nylon-6/6 are exemplified.

Abstract: 1311083 Photo-electric circuit EVERED & CO Ltd 26 March 1970 [27 March 1969] 15965/69 Heading G1A [Also in Division F4] An ignition control system for a burner with a plurality of burner units to be ignited in a predetermined sequence, the system including ignition means for lighting the first burner, preferably a pilot burner, and electrical circuitry including sensing means to sense the ignition of a burner unit and open the fuel supply valve to the burner unit next in sequence. The units are positioned so that the flame of one may ignite the next in sequence. Switches S1 and S2 are first switched on in operation of the system. Switch S2 may be thermostatically controlled and include a bi-metal strip heated by resistor R1. Unless contacts A3 and B3 are opened before the resistor R1 develops sufficient heat to trim off switch S2, the system will cut out. Ignition device Ig, preferably a spark ignition device or flow coil, and neon lamp N1 are energized. Light from lamp N1 falls on photo-sensitive resistor R3b to reduce its resistance so turning on transistor TRB and energizing relay B/3, thus closing associated contacts Bl and B2 and opening contacts B3. Closure of contacts B2 energizes solenoid Lp which acts to switch on the fuel supply valve of the pilot burner the pilot burner being ignited by ignition device Ig. Photo-resistor R3a is now operated to turn on transistor TRA, from light emitted by the pilot flame, energize relay A/3  and thus open contacts A2 and A3 and close contacts A1. Resistor R1 is now de-energized and cannot cause switch S2 to open. The ignition device Ig is also de-energized but solenoid L1 operates the fuel supply valve to the first burner unit which is ignited from the pilot flame. Photo-resistor R3c causes energization of relay C/1 to turn on the fuel supply valve to the second burner unit and the process is repeated to ignite all the burner units in sequence. Instead of a thermo-motive cut-out heated by resistor R1, a solid state switching circuit may be employed to enhance the accuracy of the delay period, particularly where a short delay time is required. A probe electrode (Pa), included in a circuit as in Fig. 2 (not shown), may replace each photoresistor to sense a burner flame.

Abstract: 1331753 Minimising explosions in containers TWEEDY OF BURNLEY Ltd 12 Sept 1970 43706/70 Heading A5A The risk of explosion damage in a storage container, e.g. a silo, is minimised by providing a lid 10 which is secured to the container by one or more nut and bolt connections 56, 58 adapted, under the action of a predetermined small internal pressure rise, to break and release the lid so that it is removable, and which has an area relative to the container capacity large enough to dissipate the increased pressure without damage. Fig. 2 shows the top of cylindrical silo 14 on which is mounted angle iron 16 whose horizontal flange 12 forms an annular outer lip to support disc lid 10. Lid 10 is internally strengthened by angle iron 18 whose vertical flange 20 is adjacent to the inner face of 14. Bolts 56 passing through lip 12, sealing gasket 22 and lid 10, and retained by.nuts 58, fasten 10 to 14 and are formed with reduced neck portion 60 so as to fracture under a predetermined load. At other positions round the top edge of 14 are mounted brackets 24, Fig. 3, and guide plates 32 which form support for upwardly projecting guide rods 30. At still other positions are mountings 36, Fig. 4, for restraining wires 38, consisting of upper eye bolt 44 secured to flange 42 of lid bracket 40 and lower eye bolt 48 secured to bracket 50 on the outside of cylinder 14. Wire 38 extending between eyes 46, 52 is of sufficient length to allow the lid and container to move clear apart (e.g. 2¢ ft). When explosion is incipient bolts 56 fracture, e.g. at 1 p.s.i. increased internal pressure, and release lid 10 which slides up rods 30 until restrained by wires 38. By this time the explosion is dissipated, lid 10 drops back into place, and new bolts can be fitted. Lid 10 may have hinged or bolted inspection cover 62 (Fig. 1) which can act as initial relief valve, and may be strengthened by crossmembers 66. Weather shield 70 may cover lid 10, retained by nut and bolt connections 56, 58. Instead of breakable bolts 56 there may be used ordinary bolts plus nuts of reduced internal thread.
