IPC: H04M19/02
Filed: 1956-08-28
Abstract: 801,576. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 28, 1956, No. 26229/56. Drawings to Specification. Class 40 (4). In an exchange similar to that described in Specification 788,592, the supervisory signals are transmitted over the speech path as voice frequency signals having frequencies above the normal speech band. In the embodiment described, dialling signals are sent forward from a link circuit to a register or to an outgoing junction relay set as bursts of a 6 kc/s. frequency and are detected by receivers tuned to that frequency. A final selector or an outgoing junction relay set when seized reverts a continuous frequency of 8 kc/s. which is detected by a tuned receiver in the link circuit. Cessation of this frequency when answering takes place causes the receiver to initiate metering. A common receiver may be connected to several circuits, the signals on the circuits being cyclically gated to the receiver by pulses in time positions allocated individually to the circuits. For metering purposes a meter such as that described in Specification 744,358, [Group XIX], may be employed. Such a meter consists of a continuously rotating drum having a number of parallel magnetic tracks, each track being allocated to a group of subscribers and providing a number of sections one per subscriber of that group. The drum also has a clock track which provides the gating pulses, and it rotates at such a speed that all circuits are scanned within the minimum time of a metering signal. If the V.F. signals on the circuits are to be utilized by those circuits, the gating pulses, as well as gating the V.F. signals to the common receiver, are also used to gate nhe D.C. output of the receiver to D.C. receivers individual to the circuits.

Title: Differential pressure forming machine
IPC: B29C51/38
Filed: 1964-06-29
Abstract: 1,029,895. Pressure forming sheet material. BROWN MACHINE CO. June 29, 1964 [July 10, 1963], No. 26743/64. Heading B5A. In a pressure forming machine, a sheet 10 of e.g. polystyrene, intermittently advanced by pairs of chains 34, 35, is heated by electric heaters 37 and then moulded by male and female die carriers 12 and 11, which are supported by brackets from lower and upper platens 27 and 21 respectively. The platens 27 and 21 are reciprocated to the moulding position along vertical guideways 19a, mounted on frame members 19, by means of cylinders 23 and 26 respectively, the final closing movement being furnished by piston operated toggle mechanisms (see Figs. 3 and 4, not shown), carried between the respective platen and cross-members 18 and 20 respectively. In operation, the die carrier 11 is first forwarded by cylinder 26 and then by the toggle mechanism, to contact the sheet 10. Platen 27 is then raised until clamping frame 51, carried by platen 27 and biased upwardly by air cylinders 60, 61, co-operates with the sheet (see Fig. 5). Further upward movement of the platen forces plugs 14 into cavities 13, the air being bled off by a suitable valve at the rate of its displacement by the plugs. The toggle mechanism is then actuated to further forward member 50 and clamp it against carrier 11, an airtight seal being formed by sealing ring 53. At this point air under pressure is introduced through pipe 55, and a main vacuum valve 91 (see Fig. 8, not shown) is opened to evacuate cavities 13 thus forming the sheet material against the cavity walls. A pressure sensitive switch 105 (see Fig. 9, not shown) is actuated when the pressure in member 12 has reached a predetermined value to discontinue the pressure at which time another valve is operated to open member 12 to the atmosphere. Air at atmospheric pressure is then introduced into cavities 13, the lower and then the upper platens withdrawn, the sheet indexed forward and the moulding cycle then repeated.

Title: Improvements in reheat control systems for gas turbine engines
Inventor: GREENLAND LEONARD SIDNEY
IPC: F02K3/10
Filed: 1957-03-01
Abstract: 833,880. Gas-turbine jet-propulsion plant. HOBSON Ltd., H. M. Aug. 27, 1957 [March 1, 1957], No. 26796/59. Divided out of 833,498. Class 110 (3). A gas-turbine jet-propulsion engine in which reheat fuel is ignited by injecting fuel into the main combustion chamber in advance of the turbine has an accumulator for the reheat ignition fuel comprising a vessel arranged to fill slowly with fuel during periods when reheat is switched off and means operating automatically, in response to the pilot turning on reheat, first to open a shut-off valve or valves to allow fuel to flow to the reheat burner or burners and then, after a predetermined time delay, to cause the vessel to deliver its fuel content to the igniter jet. By stating that the vessel fills slowly with fuel is meant that the time required for the vessel to accumulate a sufficient charge of fuel to effect a subsequent reheat ignition is sufficiently long to enable the turbine blades to cool to a safe temperature. The accumulator cylinder 13 is initially filled with fuel from a conduit 23 through a passage 11 containing a non-return valve 12. When reheat is selected by the pilot, a solenoid 30 is energized and valve 31 opened. This causes a reduction in pressure on the left-hand side of the piston 32 which then moves to the left and allows fuel to flow to the primary and main reheat burners through ports 33, 34, respectively. The delay before the piston 32 strikes the rod 36 and open a control valve 56 is sufficient to allow the fuel lines to the burners to fill. The delay is controlled by the spring 35. When the valve 56 is opened, the fuel pump delivery pressure is admitted to the space 7 and causes the piston 9 to move against spring 10 and deliver fuel in the cylinder 13 to igniter jets in the main combustion chamber via non-return valves 14. When the pilot returns his lever to the original position the valve 31 closes and the servopiston returns to the position shown, enabling a spring 37 to re-close valve 56. The spring 10 then returns the piston 9 which forces fuel in the chamber 7 along the line 38, around the waisted central portion of the valve 56, line 39 and passage 11 into the cylinder 13. The restrictor 111 ensures that the cylinder 13 only refills slowly. The time required for the cylinder 13 is sufficiently long to enable the turbine blades to cool to a safe temperature. The piston 32 controls the valves 45 regulating the supply of purging air to the burner fuel lines. The valves 45 are closed by the initial movement of the piston 32 and lost motion (not shown) between the valves and the stem of the piston 32 allows the valves 45 to close before the valves 43, 44 are opened.
