Abstract: 373,430. Glass annealing leers. POLLAK, J. E., 20, Holborn, London.-(Hazel- Atlas Glass Co. ; 16th Street, Wheeling, West Virginia, U.S.A.) June 4, 1931, No. 16330. [Classes 51 (i) and 51 (ii).] In a glass annealing leer in which the conveyer extends beyond the end of the tunnel, the whole of this extension, including the sprockets, is enclosed, as shown in Fig. 4, by heat-insulating side and bottom walls except the end discharge section of the upper run. The leer proper comprises sides and roof of heat-insulating material 38 reinforced by metal straps 41 carried by longitudinal channel beams 7 constituting the side frames of the leer. For some distance beyond the termination 44, Fig. 2, of the upper refractory structure, the tunnel is continued in the form of telescopic metal hoods 55 in rear of which is disposed a device 56 for projecting cooling air on to the ware, the air supply apertures 57 being graduated so as progressively to increase the amount of cooling air supplied. The leer is movably mounted by means of front rollers 2 and vertically adjustable supporting rollers 5, while the conveyer comprises pans 27 secured to endless chains 21 and carrying rollers 28 adapted to run on guide-rails 29. The latter extend the full length of the leer and are anchored at one end only to allow expansion and contraction, guide-rollers 35, Fig. 4, being provided on the cross-beams 8 to maintain the rails in correct alignment. The leer is fired by burners 17 delivering into a combustion chamber 10 which is detachably secured to the side frames 7 and is provided internally with baffles 10<1>, 10<11>, Fig. 7, to cause the gases to take a circuitous course before entering the leer through port 10<111>. A number of spaced damper-controlled outlet flues 45 is disposed in the roof of the leer, while, to reduce air currents, there are provided at intervals vertically adjustable metal or asbestos curtains 47 which are slidable through the roof and are operated by cranks 51. To prevent too sudden a fall in temperature, the rear end of the refractory upper part of the tunnel is fitted with a battery of cooling pipes 52, Fig. 2, which are open to the atmosphere at their rear ends and deliver, at their front ends, to a damper-controlled flue 53.

Patent GB-1108369-A (GB)
Title: Improvements in apparatus for moulding articles from plastics material
Inventor: SCHNEIDER JACK MARVIN
IPC: B29C51/18
Filed: 1964-04-22
Abstract: 1,108,369. Sheet forming. CALMEC EXTRUFORM Ltd. 22 April, 1965 [22 April, 1964; 21 Oct., 1964], Nos. 16731/64 and 42903/64. Heading B5A. Hollow articles are formed from freshly extruded plastics sheet material 6 by cooperating hydraulically operated platens mounted upon a carriage 85, the carriage being advanced down columns 16 with the sheet during the moulding operation and being retracted to its original position after disengagement of the platens in order to mould a succeeding portion of the sheet. The sheet is driven downwards by upper and lower pairs of co-operating rotating rollers 18, 19 and 21, 22 respectively, driven by chains 52, 53 which also engage a clutch mechanism mounted upon the carriage. The carriage itself is mounted upon columns 16 by four hollow cylinders 86, a diagonal pair of which slide over pistons fixed to corresponding columns so that by applying pressure fluid above or below the piston the carriage is retracted or advanced, the rate of advancement being controlled by chains 52, 53 actively engaged therewith by the abovementioned clutch during said advancement. The other diagonal pair of cylinders 86 slide over smooth columns and are filled with pressure fluid which actuates, via suitable flexible connections, platen operating cylinders mounted upon the carriage. One of the platens carries female vacuum moulds (see Figs. 7A-7E, not shown) about which are located cutting blades, whilst the other comprises a flat platen, having blowing orifices, which may carry assist plugs if required. During the moulding the platens are advanced into contact with a stop device, in which position the cutting blades partially penetrate the sheet. After the moulding operation the platens are put under greater pressure and, despite the stop device, the inherent resilience of the platens allows them to move closer together and completely sever the sheet. Instead of using a sheet, an extruded tube may be used being guided between platens both of which are connected to a vacuum source, and which seal the tube. The article thus formed is then removed and fully formed at a second station.

Title: Improvements in toy tanks or like vehicles
IPC: A63H15/00
Filed: 1941-12-30
Abstract: 554,382. Mechanical toys. HAYDON, J. L. and PARK, W. M. Dec. 30, 1941, No. 16795 [Class 132 (iii)] A toy tank or the like has a pendulum supported within the tank body and wholly between the side walls of the tank so as to project beyond the lower flight of the track of the vehicle without projecting laterally and present a surface relative to which the body of the tank may move, the lower surface of the tank being formed with projections or contoured to permit a rocking movement of the body in relation to the surface of the pendulum. A miniature tank has a hollow body in which is mounted a transverse spindle H carrying a pendulum I consisting of two disc members protruding slightly below the track surfaces B. When placed on a sloping surface, the tank swings forward about the bob of the pendulum until the projection M strikes the ground and the pendulum is lifted clear of the ground and can swing forward. As the tank swings back again, the pendulum again contacts the ground. The swing of the pendulum is limited by abutments L which may be in the form of cams so that the swing can be varied. The gun turret N is rotatable.

Inventor: CHIABERTA GIOVANNI
IPC: B23G9/00
Filed: 1950-07-05
Abstract: 673,296. Milling; nicking screw heads. B.E.V.I. BULLONERIA E VITERIA ITALIANA SOC. AR. L. July 5, 1950, No. 16816/50. Class 83 (iii). [Also in Group XXIII] A screw-nicking machine has a pair of rotary hoppers 3 feeding screws to vices arranged round a table 15 which is rotated step-by-step to present the screws from each hopper to each of two separate sets of milling cutters 44. An electric motor in the machine, bed drives a toothed wheel 10 which is rotatable on a central shaft 11 and is geared to a pair of cam-shafts 14 and to driving-shafts 37 connected to the cutter spindles.. One of the shafts 14 carries a cam 22 for imparting the step-by-step movement to the table 15 by means of a lever 21, Fig. 6, linked to the table by a spring-loaded rod 20, a lever 19, a pawl 18 and a ratchet 17. Each cutter spindle is mounted for vertical adjust. ment by a screw 45 on a pivoted arm 39 which can be adjusted angularly to vary the depth of cut by screw 46. The vices 16 comprise a fixed part 25, Fig. 10, and a spring-loaded movable part 26 which is pulled back by the engagement of a groove 29 with a profiled plate on the machine bed, as the vices approach the ejectors 31 operated by a cam 32 on each shaft 14, and is released again after a screw has been delivered from the hopper discharge 5. Each half of the machine may operate on different types of screw and the finished screws fall down inclined channels into central conduits 33 and thence into containers 34. If a screw is incorrectly gripped in a vice, it actuates a projection on a lever 23 and raises the lever 21 out of range of the cam 22, so stopping the table and, at the same time, closing a switch for an audible or visual warning signal 24.
Patent GB-925837-A (GB)
Title: Improvements in or relating to extrusion apparatus for the manufacture of shaped artiles such as filaments or films
IPC: B29C48/38
Filed: 1960-05-12
Abstract: <PICT:0925837/IV(a)/1> A melt extrusion apparatus for the manufacture of shaped products or such as filaments and films of thermoplastic polymeric material comprises a hopper 1 from which the material in particulate form is fed to a screw extruder and is forced by the rotating screw 2 of the extruder towards a buffer space 6 communicating by means of ducts 7 with the suction side of two metering pumps 8 which feed the molten material under pressure through ducts 9 to extrusion nozzles 10.  The casing 3 of the extruder is provided with a cooling jacket 4 and heating collars 5. The screw 2 is driven by the infinitely variable speed power transmission gear 19 through pinion 20, gear-wheel 12, shaft 13 and splined coupling 11.  Shaft 13 having gear-wheel 12 fixedly mounted thereon and the screw 2 are axially displaceable and the pinion 20 is of such length that the gear-wheel 12 throughout its entire range of axial travel remains in engagement with the pinion.  A hydraulic liquid is supplied at a constant predetermined pressure to a cylinder 14a containing a piston 14 the rod 15 of which is coaxial with shaft 13 and in contact with one end thereof.  The speed control lever 18 of the infinitely variable gear 19 is connected by means of link 16 and arm 16a with the piston rod 15 in such a manner that the rate of rotation of the screw 2 increases progressively as the screw moves axially from left to right and projects further and further into the buffer space 6.  Thus, when the rate of feed of material by the screw becomes too small, the consequent axial movement of the screw from left to right automatically increases the rate of feed of material by the screw.  Conversely, when the rate of feed of material by the screw to the metering pumps becomes excessive, the rate of rotation of the screw is automatically decreased.  The predetermined axial pressure may be applied to the extruder screw by means of compressed air or pre-tensioned springs instead of hydraulically.  The apparatus automatically maintains constant the pressure on the material between the discharge end of the extruder and the metering pumps, thereby promoting uniformity of the rate of delivery of materials by the pumps.

Title: Fluid flow control valves
IPC: F16K1/226
Filed: 1973-04-09
Abstract: 1366065 Valves SULZER BROS Ltd 9 April 1973 [21 April 1972] 16898/73 Heading F2V The closure member of a butterfly valve for use in nuclear power stations comprises two substantially similar disk-like parts 6, 7 bolted together at the centre, each carrying one of a pair of trunnions mounted in ball bearings. A ring 15 is clamped in a peripheral recess 10 between the parts 6, 7 and an annular inflatable sealing member 16, of omega-shaped crosssection, is pushed on to this ring and clamped between the parts 6, 7. An 0-ring 21 in a groove 20 seals off an annular space into which inflating fluid is fed via a passage 23 in one of the trunnions. The other trunnion is provided with an operating lever 42 connected to a compressedair operated piston 92. The valve is opened by operating a switch 62, which may be pressure operated, that energizes an electromagnet 64 to move the spool 70 to the position in which the line 82 is connected to exhaust thus relieving pressure within the sealing ring 16. At the same time current is fed to the electromagnet 65, but via a delay element 66, which moves the spool 71 to the position in which compressed air from the reservoir 88 operates the piston 92 to open the valve. To close the valve the switch 62 is opened which immediately releases the electromagnet 65, since delay element 66 does not provide a delayed switch-off, thus moving the spool 71 to release pressure in the cylinder so that the piston 92 closes the valve under the action of the spring 95. Delay element 58 is now operative to delay the release of the electromagnet 64 so that pressure fluid is not fed to the sealing ring 16 until after the valve has closed.

Abstract: 415,234. Timepieces. FRANCIS, E. L., 88, Chancery Lane, London.-(Hamilton Watch Co. ; Lancaster, Pennsylvania, U.S.A.) June 14, 1933, No. 17026. [Class 139.] Testing balances.-Apparatus for studying a body having periodic motion comprises means for rendering the body momentarily observable at constant time intervals, means for varying the time of the moment of observation in relation to the cycle of movement of the body, and means for measuring the said variation. The invention is described in connection with the checking of the period of the balance wheel of a watch ; the wheel being illuminated by light flashes having a frequency equal to the correct oscillation frequency of the wheel. The phase of the light flashes is initially adjusted so that a selected part of the wheel appears stationary at a particular point in the field of view and so that the wheel is observed whilst moving with its maximum velocity. If the frequency of the wheel is not exactly the same as that of the flashes a further phase adjustment of the flashes is required after a given time to make the said part again appear stationary at the same point in the field of view, the said further adjustment being a measure of the error in the frequency of the wheel. As shown, light from a source 13 passes through a lens 14 to a mirror 10 mounted on the shaft of a synchronous motor 17, and is reflected, once in each revolution, through a stationary slit 15 to illuminate the balance wheel. The phase of the flashes can be varied by rotating the motor housing 16, the angle of rotation being indicated by a pointer 21 on a scale 22.
