Abstract: 1,209,209. Glass annealing lehrs. E. W. BOWMAN. 19 Aug., 1968, No. 39646/68. Heading F4B. A glassware annealing lehr comprises heat treatment zones 9-15, separated by insulating walls 29, 30 and all traversed by a gas permeable belt link conveyer 8. The ware first enters heating zone 9 wherein it is heated by vertically adjustable fire-polishing burners 16 and radiant cup burners 20 from above, and burners 23 mounted under stainless steel reflector plates 24 from below, and then passes through zones 10 to 12 wherein it is further heated by the circulation of hot air. In these zones the air is continually circulated by fans 34 along ducts 33 containing heaters (33b, not shown), through slots 5a in aprons partly defining the ducts 33, through the conveyer 8 and over the ware. It is then drawn back to the fans 34 through side flues defined between the sheet metal walls 25a and the walls 29, and the ducts 31. Damper controlled fresh air inlets and exhaust air outlets 52, 36 respectively regulate the volume of fresh air entering the circulation systems and so the gas volumes and recirculation rates and the zone temperatures. In zones 13 and 14 air is similarly recirculated but without the addition of heat, whilst in zone 15 cool air is recirculated for rapid cooling of the ware before discharge. In a modification (not shown) the zones may be arranged in a straight line. The conveyer (Figs. 5 and 8, not shown) is formed from crescent-shaped members mounted on chain links that at the ends of each zone engage with idler and driven sprocket wheels, to reverse the conveyer path for travel through the subsequent zone. Adjustable doors are provided at the ends of the zones.

Abstract: 928,292. Ignition systems. GLOBEUNION Inc. Nov. 23, 1959, No. 39719/59. Class 7(4). An oscillator ignition system having a primary circuit and an inductively coupled secondary circuit comprises a self exciting transistor oscillator in the primary circuit including a pair of transistors connected in push-pull relationship each of the transistors being associated with an oscillator winding and a feedback winding, a unidirectional voltage power supply being connected to the oscillator, a distributor and a spark plug being provided in the secondary circuit and means being provided to regulate the oscillator in relation to the operation of the distributor the means being operative in synchronized relation to the distributor to reduce the induced voltage in the feedback windings. In the high tension system of Fig. 1 the switching of the oscillator comprising transistors 16 in time with the engine speed is accomplished by a switching winding 22 of the step up transformer which is shorted momentarily by breaker points 24. Alternatively there may be other means for switching such as shunting the feed back winding 14 as indicated in the broken lines of Fig. 1 or shunting part of the collectorprimary winding 12. The oscillator is heavily loaded and oscillation prevented whenever the switching means is operated to this end. In the high tension system of Fig. 2 (not shown) a class B amplifier is used to step up power output and voltage for high speed multicylinder engines. In a low tension system creepage type plugs are employed. The ends of the secondary winding are connected to a full wave voltage doubler circuit comprising two rectifiers and two condensers. The condensers are connected to a distributor supplying the sparking plugs. This system does away with cam operated switches.

Filed: 1972-08-29
Abstract: 1378019 Television; cathode-ray tube displays SINGER CO 29 Aug 1972 [20 Sept 1971] 39991/72 Headings H4F and H4T In order to display on a curved viewing surface, in proper perspective to an observer at its centre of curvature, information stored for display either on a planar surface or as digital image signals in a generator 30, a raster of lines each of which is a projection of a corresponding straight line in a nominal display plane is traced on the curved surface, a function is computed which describes the spot position on the nominal plane corresponding to the instantaneous scanning spot position on the curved surface, and the function is used to control the image generator 30 to scan the planar surface or read the stored digital image signals so as to produce a video signal for the curved surface. Preferably the curved surface is spherical and is scanned along great circle lines, scanning equal angles in equal time intervals. The instantaneous position of the scanning spot on the nominal plane is related to the instantaneous angle of the scanning beam by a tangent function. The method may be applied to an aircraft simulator in which a wide angle display is derived from a plurality of narrow angle displays, in which the rasters are so related that a continuous scan appears to occur over the whole display. In Fig. 5, a sync. generator 24 controls the application of relatively delayed sweep signals to the three displays, controls the switching of the video signal from one display to another through switching device 37, and is connected to control unit 39. The control unit produces an image generator sweep signal which is applied to image generator 30. The unit includes a function generator which computes the required non-linear scanning signal which may be applied directly to a scanned raster image generator 30, but is applied to a variable frequency clock if generator 30 is a digital image generator, whereby the stored information is read out at a variable rate. The displays include respective display raster computers to cause the rasters to scan great circles on the display screens. The method may also be applied to cylindrical display surfaces, or other shapes. The image generator may be a TV camera or a flying spot film scanner.
