Patent GB-1042377-A (GB)
Title: Improvements in or relating to the manufacture of a glass strip
IPC: C03B18/04
Filed: 1963-08-14
Abstract: In a process for forming a glass strip continuously drawn under its own weight through a slot in the bottom of a melting tank containing molten glass, the glass strip is, by the exertion of a traction effect on the strip where it cannot be damaged by the traction means, directed laterally, without contacting any solid elements, through a natural curve on to the surface of a bath having a density higher than that of the glass, the temperature of the bath decreasing in the direction of movement of the strip floating thereon.  The glass strip 7 (Figs. 1 and 3, not shown), issues through a slot 4 and may pass through a drawing chamber 13 before entering the tank 9 containing the bath of molten liquid 10 which is denser than the glass, e.g. of tin, tin alloy, silver or mineral salts, the level of the molten liquid 10 being disposed below the slot 4.  The strip passes through tank 9 along the surface of liquid 10 and is progressively cooled by controlling the thermal gradient along the length of the tank 9, and is then drawn into a lehr by traction rollers 8. The chamber 13 may be completely sealed from the atmosphere and may be placed between the slot 4 and tank 9 and may contain temperature control means.  A controlled atmosphere of an inert gas, such as nitrogen, is maintained within the tank 9.  Reference has been directed by the Comptroller to Specifications 769,692 and 937,738.

Title: Improvements in or relating to sluice valves
IPC: F16K31/50
Filed: 1922-11-27
Abstract: 203,242. Autier, V. Nov. 27, 1922. Actuating - mechanism.-In a sluice valve, the valve member is divided into three parts, two outer discs and a central disc. The central disc engages with a screw of quick thread forming part of the spindle, the two parts being connected by a screw of slow pitch, so that the end of the opening movement and beginning of the closing movement are slow. The operating stem 6 is provided at its inner end with two threads, a quick-pitch thread 10 the threads of which are half the width of the recesses, and a slowpitch internal thread 11. The extension of the spindle 22 is provided with a quick-pitch thread 13 having the same pitch as the thread 10, but having the threads double the width of the recesses. The valve comprises three parts, an inner disc 14 and two outer discs 15. The disc 14 has four recesses 16<1> the faces of which are spherical and concentric, and the upper end of its internal quick-pitch thread terminates in a cylindrical portion slightly longer than the shoulder 22 which it receives. Projections 17 are formed on the inner faces of the discs 15, which engage with the recesses 16<1> on the disc 14 to hold the discs 15 in position, and the outer faces of the discs 15 are slightly inclined to one another so that the valve forms a wedge. Lugs are provided on the edges of the disc 14 to engage in vertical grooves in the casing. The first part of the downward movement of the valve is effected by the action of the quick-pitch screw 10, and is rapid. The disc 14 then becomes rigid with the extension 22 owing to the engagement of the stops 24, 26, and the closing movement takes place under the action of the slow-pitch thread 11. On reversing the rotation of the actuating spindle, the initial movement of the valve is slow, and is followed by a rapid movement.

Title: Improvements in and relating to meat slicing machines
IPC: B26D1/18
Filed: 1926-12-23
Abstract: 286,811. Thomson, D. B., and Sinith, C. B. Dec. 23, 1026. Cutting slices in succession.-In a reciprocating disc knife slicing machine, the knife reciprocates vertically and cuts on the down stroke. As shown in Figs. 1, 2, the knife c is carried in a frame c slidable on posts d joined on the top by a bar j<1> having lugs j carrying slidable spindles i<2> which carry the tops of rack members i<l>, the bottom being carried on similar spindles i<2> slidable in brackets k on the base a. The racks comprise pins i projecting from plates, and a curved guide l is disposed below the pins. The racks are slidable in the plane of meshed pinions g, h, the pinions h engaging with pins i. Buffer springs are coiled on the spindles i<2>. At the end of the downward stroke, the pinions h encounter the guides l and being prevented from moving downwards, move the racks to the right (as seen in Fig. 2), and then travel up on the other side of the racks. The rotation of the knife is continuous in one direction. At the top of the stroke, the racks return to their previous position and the pinions h travel down the right hand side of the racks. The frame e contains a shaft f, carrying the pinions g and connected to a handwheel x', and bevel and sprocket gearing for rotating the knife. The frame e in its upward stroke raises a slider o on the. post d, and actuates a pawl p<1> through links o<1>, o<2>. The pawl p<1> engages a ratchet wheel connected to the feed screw q<1> through bevels. The slice thickness is regulated by a ratchet shroud, adjustable and locked by a rod r<1>. Rapid adjustment of the feed table is effected by a handle p<3>. A support u slidable on rods u<3> holds the meat against the cutter, and is automatically moved away from the meat during the feed motion by a flexible member u' which is connected to the support u and passes over pulleys to the link o<2>. A spring v tends to press the support against the meat. The clamp consists of a flexible metal band s secured to two box-like casings s<1> slidable one on each upright s<3>, and levers t pivoted at t<1> to the casings s<1>, provided with wedge-like projections t<2>, Fig. 6, which grip the uprights when the leavers t are depressed. An abrasive member, normally inoperative, may be pressed by a spring against the knife when it requires sharpening. The Provisional Specification describes a curved guide at the top of the rack in addition to the guide l.

Title: Oscillator circuits
IPC: C11D3/39
Filed: 1972-07-13
Abstract: 1393767 Keying oscillators; magnetic storage arrangements WESTERN ELECTRIC CO Inc 13 July 1972 [19 July 1971] 32779/72 Headings H3B and H3R An oscillator circuit includes a tuned circuit having a capacitor and at least one inductor, means for precharging the capacitor, switch means responsive to an energizing signal for completing a loop including the tuned circuit to initiate an oscillatory current therein, means for maintaining the oscillatory current at a predetermined value, and means connected across the switch means for terminating the oscillatory current at the end of an oscillation cycle upon removal of the energizing signal during a predetermined portion of the cycle. In a tuned circuit comprising capacitor 1, Fig. 1, main inductor 19 and auxiliary inductor 9, the capacitor 1 is held charged, in the static condition, by means of a current source comprising resistor 8. Upon an energizing signal e 1  being applied to its base, transistor 4 becomes conductive and closes the tuned circuit, which is then maintained in an oscillatory condition by means of amplifier 5, which derives an input from point 26 over 90 degrees phase-shifting circuit 11, and is biased from source E2 to provide class C operation. When the energizing signal e 1  is terminated oscillations cease; diode 3 connected in the reverse direction to the base-emitter junction of transistor 4 ensures that the oscillations terminate at the point in the cycle at which capacitor 1 is fully charged. Magnetic domain propagation circuit.-For use in such an arrangement, two of the abovedescribed circuits may be combined so as to provide a rotating magnetic field, the inductors 2, 2<SP>1</SP>, Fig. 2, of the two circuits 20, 30 being arranged mutually, perpendicular. The base of the transistor 4 is coupled directly to the control circuit 17, while the base of the transistor 4<SP>1</SP> is coupled thereto over a delay network 16. In addition, the device for the amplifier 5<SP>1</SP> is derived from the point 26 in the circuit 20, without interposition of a 90 degree phase-shifter. The control circuit 17 comprises a bi-stable circuit 27, the initiating control signal e 1  being applied to its "set" input S and also to AND gate 29 and OR gate 28. Switching off is determined by an input to the "reset" input R which is derived from AND gate 24, the two inputs to which are derived from input e 1  and a signal derived over diode 21 from the tuned circuit 1, 2: the latter ensures that switching off is performed in the correct part of the oscillation cycle. The Specification also describes a modification of this arrangement (Fig. 3, not shown) in which switches are provided whereby the direction of rotation of the magnetic field can be reversed.
