Title: Improvements in the manufacture of glass, or similar thermoplastic products in sheets
IPC: B29C48/355
Filed: 1963-03-01
Abstract: <PICT:1028321/C1/1> Sheets of glass or similar thermoplastic material are supported, particularly during transport, on a number of liquid supports. The liquid, which is preferably a metal such as tin or lead, may be supplied through orifices in a solid base or through a porous base, and the supports can be obtained by filling cavities formed in the surface of a solid base.  The liquid is non-reactive towards the glass and may also be non-wetting towards the base so that its surface tends to extend above the surface of the base to form a support for the glass; alternatively, it may be placed on limited regions of the support which are wettable by the liquid. The cavities may be in the form of circular or elliptical recesses or rectilinear or non-rectilinear channels, e.g. in the form of arcs or chevrons with the apex pointing in the direction of travel of the glass.  The channels are preferably arranged transverse to the direction of travel; if, however, they are arranged longitudinally, sections are staggered relatively to one another. The underlying support may be flat, curved, or undulating, and may slope upwardly or downwardly in the direction of travel to retard or accelerate the movement respectively. Passages may be formed in the support for the passage of a heating or cooling medium. The edges of the glass sheet may overlap the recesses and contact a cooled solid surface. Provision may be made for the supply of a neutral gas, e.g. hydrogen, to prevent oxidation when a molten metal is used.  As shown, the apertures may be formed in a block 34 and channels 36, 37 provided for leading the liquid back for recirculation.

Title: Apparatus for automatically multiplying time intervals
IPC: G04F3/00
Filed: 1929-03-14
Abstract: 324,845. Hansen, J. P. March 14, 1929. Time signals.-A time signal for use in photographic and other processes is automatically released at the end of a period which is the desired multiple of a variable time interval, this multiple being obtained automatically by the operator pressing a button when, for example, the first traces of the image appear on the immersed plate, whereupon a member moving at a uniform speed traverses a distance previously traversed at a higher speed corresponding to the desired multiple. When the plate is first immersed the operator depresses a button 23 so as to withdraw a stop 21 from an abutment 20 on a wheel 9, which is thereupon free to be driven by clockwork through a coupling 4, a pinion 3 and a pin 15. Simultaneously, through gearing 3, 6, 7, a wheel 12 is driven at a lower speed than the wheel 9, the ratio of the speed reduction corresponding to the desired multiple. A stop 19 on the wheel 9 thereupon moves away from a spring-hook 18 on a wheel 11, the hook 18 being released to engage a pin 16 carried by the wheel 12 and passing through an elongated slot 17 in the wheel 11 The wheel 11 is thus coupled to the wheel 12. When the image first appears, a button 14 is depressed to its maximum extent, thereby disengaging the pinion 3 from the pin 15 and displacing the wheel 9 so that it comes into engagement with a locking member. The wheel 12, however, continues to drive the wheel 11 until the pin 16 strikes a stop 25 on the now stationary wheel 9, whereby the stop 19 lifts the spring-hook 18 and releases the pin 16, enabling the wheel 11 to rotate under the influence of a spring until the end of the slot 17 strikes the pin 16, this movement being used to give the desired signal. To obtain other values of the gear ratio, a gearchanging device may be used. In a modification a wheel is arranged to turn backward through the same angle as it previously turned forward but at a reduced speed corresponding, to the desired ratio. Racks may be used instead of gear-wheels.

Title: Improvements in or relating to guards and control mechanism for power presses and like machines
IPC: F16P3/04
Filed: 1949-03-29
Abstract: 663,933. Machinery guards. PRESS GUARDS Ltd., and EVANS, F. A. May 25,1950 [March 29, 1949], No. 8452/49. Class 80 (iv) A control unit for a guard and clutch is housed in a casing 19 mounted on a convenient part of the frame 10 of a press and is linked to the existing clutch pedal 14, to a shaft 24 carrying a swinging guard and operating a sliding guard, and to the clutch-actuating lever 18. The unit, Fig. 3, comprises a bell-crank 30, 35 pivoted at 29 and linked through one of the holes 31 to the pedal shaft arm 17. An abutment 33 on the bell-crank is engageable with a fixed stud 34. The arm 35 is pivoted to a push rod 22 (or through a reversing lever to a tension rod) actuating the guard and carries a cam 37 to engage a roller 38 actuating a valve 39 supplying compressed air to a pivotally-mounted cylinder 41. The piston rod 42 is connected to a lever 45 which is pivoted at 46 and is linked to the lever 18. An adjustable spring-loaded telescopic link 49, anchored in a fixed lug 50, is pivoted to the lever 45 and holds the piston at the bottom of its travel. When the pedal 14 is depressed, the arm 35 first closes the guard and then operates the cylinder 41 to engage the clutch. On release of the pedal the rod 20 is raised by a spring 15, the air supply to the cylinder 41 is cut off, and the spring 51 disengages the clutch. The rod 22 has a lost motion coupling allowing the guard to remain closed and means may be provided for locking the guard until the press has completed its cycle. Where the pedal originally operated the clutch through a push rod, the bell crank may be reversed on its pivot and the rod 21 connected directly to the fork 43. In a modification the bell crank 30, 35 is replaced by a compressed air cylinder controlled by a valve linked to the pedal 14, the air preferably passing through a reducing valve to prevent injury to the operator when closing the guard. In the Provisional Specification the fork 43 is described as having a slotted pivotal connection with the lever 45.

Title: Improvements relating to super-regenerative receivers
IPC: H03D11/02
Filed: 1943-06-01
Abstract: 566,209. Super-regenerative circuits for wireless reception. FERRANTI, Ltd., TAYLOR, M. K., and JONES, 1. N. VAUGHAN-. June 1, 1943, No. 8740. [Class 40 (v)] A super-regenerative receiver comprises a single oscillator valve having a cathode, an anode and three grids with the input connected to the first grid and feedback to the input from the anode and from the second grid in opposite phase and having a quench frequency applied to the third grid. The relative durations of the feeding of each phase is determined by the grid bias applied to the third grid. In this way quenching is effected rapidly so that a larger time is available for the building up period, while ensuring that each pulse decays completely. The Figure shows a tetrode valve with the input applied to the grid 2 and the quenching pulse to the grid 17, feedback in opposite phase is taken from the anode 9 and the grid 12 to the coils 11, 13, the feed from the coil 11 being negative and that from the coil 13 being positive. Alternatively, positive feedback from the anode and negative feedback from the auxiliary grid may be used. In either case, the negative feedback may be by capacitive instead of magnetic coupling.

Class 82(1) [Also in Groups XI and XII] Zinc-containing materials containing zinc oxide are mixed in granular form with granular carbonaceous material and are charged to the reaction space 31 of an electrical resistance furnace by means of a feed screw 131, the charge in the furnace forming a mass having a sloping surface 139 and the mixture being fed below this surface so as to force the materials outwardly towards the surface where it is heated by radiation to reaction temperature, preferably 2300‹F. The zinc formed is vaporized and removed to a condenser. The slag, copper matte and iron metal formed as a residue is pushed forward by movement of the charge and falls into well 37 where it is heated by radiation to a temperature at which it is sufficiently liquid to be tapped from the furnace. To ensure collection of any precious metal content of the initial material copper or copper oxide or other copper bearing material and cast iron or a reducible iron compound may be added to the charge to ensure production of sufficient iron and copper matte to remove the precious metals. Preferably carbon is used in excess to the extent of 5-30 per cent of that required to react with the reducible constituents. If the residue is not required to be sufficiently liquid to be tapped the excess of coal or coke used may be greater, say 80-125 per cent. Specification 678,263 [Group XI] is referred to.

Title: An improved method for the continuous production of cream of constant fat content
IPC: A01J11/10
Filed: 1949-04-01
Abstract: In a process for the continuous production of cream of constant fat content milk or less concentrated cream is centrifuged and the values of the electrical resistance or the dielectric constant of both the cream and the skim milk discharged from the centrifuge are continuously determined and from these two values there is derived a value for the fat content of the cream, and the setting of the centrifuge is adjusted to maintain this last value constant.  In producing butter, milk is first separated to give skim milk and cream having a fat content of 30-40 per cent, the cream being then treated in a second centrifuge to yield cream of 80 per cent or more fat content.  It is generally most convenient to operate the first centrifuge at a fixed setting and to regulate the second centrifuge as above.

Abstract: 828,680. Tubular heat exchangers. FOSTER WHEELER Ltd. March 20, 1958 [March 20, 1957], No. 8963/58. Class 64(3) In a shell and tube type heat exchanger in which a fluid flowing through vertical tubes 18 carried by a tube sheet 14 at the lower end of the shell 12 is heated by a superheated vapour flowing over the tubes, partitions (e.g. 27, 28, 30, 35, 36) define a space 42 containing part of the tube bundle and are supported (e.g. by a plate 31) so as to permit expansion and contraction without contacting the tube sheet, the arrangement being that superheated vapour is admitted to the space 42 and is cooled by contact with the tubes therein before being discharged through an outlet 44 into the shell space where, after flowing over the remaining tube surface it is discharged as condensate through an outlet 56. In the form shown, feed water flows from an inlet 19 through the tubes 18 to an outlet 20 and is heated by steam flowing over the tubes. The steam condensate produced in the upper part of the shell, after the steam has been desuperheated in space 42, collects in a space 55 defined in part by a partition 25, the flow of condensate through outlet 56 being so controlled by any conventional means as to keep constant the liquid level in space 55. In a modification the partition 25 does not extend to and in contact with the tube sheet 14 so that condensate collects on both sides of the partition, the level of condensate being maintained below the bottom plate 36 of the desuperheating zone 42 and above the lower edge of the partition 25.
