IPC: B29C51/10
Filed: 1952-01-24
Abstract: 720,108. Moulding hollow articles from thermoplastic sheet material. ROBINSON, Ltd., E. S. & A. Jan. 21, 1953 [Jan. 24, 1952], No. 1977/52. Class 87 (2). When a hot sheet 39 of thermoplastic material is sucked down onto a die surface 13 by suction through pipe 17 and conduits 18 in the die body 12, the periphery of the sheet also is sucked down against the edge of the die body by suction through conduits 19 also in the die body, whereby access of air to the space between the sheet and the surface 13 is precluded. The die body is formed on its upper surface with a recess 14 and a raised planar portion 15 which constitute a labyrinthine seal. The sheet 39 is heated by contact with a hot plate 28 on a pressure head 21, the sheet being blown against the plate by compressed air passing through 17, 18. The plate 28 is heated by a chamber 27 containing, e.g., electrical heating elements, and has an air passage 29. The pressure head 21 is carried by lever 23 connected to link 25 pivoted at 26 on base 10, and slides on pillars 20. The pressure head carries a plate 30 backed by compression springs 34, and this plate presses the periphery of the thermoplastic sheet against surface 15. A microswitch 36 co-operates with a pin 38 adjustably mounted in head 21, and when the head descends to the Fig. 3 position the switch is closed to set in operation an automatic working cycle in which (a) compressed air is admitted through 18 to force the sheet against the hot plate, (b) the compressed air is cut off and suction substituted, whereby atmospheric air through. 29 presses the sheet against surface 13, (c) a signal visible or audible to the operator is given, whereupon the operator raises the head 21, and at or about the same time the compressed air is re-applied to blow the moulded article off the surface 13, and (d) the compressed air is again cut off. The die body may be cooled.

Title: Improvements in or relating to radar systems
IPC: G01S13/58
Filed: 1947-01-24
Abstract: 626,236. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 24, 1947, No. 2337. Convention date, Sept. 13, 1941. [Class 40 (vii)] In a pulse radar system for indicating the relative velocity of a target, an auxiliary oscillation, e.g. a pulse train, having a recurrence frequency which is integrally related to the recurrence frequency of the system is applied together with the echo pulses, or signals derived therefrom, to a device which is only responsive when an echo coincides with a predetermined phase point of the auxiliary oscillation, means being provided responsive to said device for indicating the coincidence frequency which is a function of the relative velocity. As shown in the Figure, the output from an oscillator 21 is shaped in the pulse generator 1, the output, from which triggers the transmitter 3 and the echo pulses are applied through the receiver 9 and detector 13 to a coincidence circuit 15, together with auxiliary pulses of the same recurrence frequency obtained by applying the output from oscillator 21 through a phase-shifter 23 and pulse generator 27, the phase-shifter 23 being adjusted so that the echo and auxiliary pulses coincide at some datum time. If the target is moving radially with respect to the radar system, the subsequent echo pulses will no longer coincide with the auxiliary pulses except when the target has moved a radial distance of nX/2 from the position it occupied at the datum time, where n is an integer and X is the distance traversed by radio waves during the recurrence period of the system and the frequency of such coincidences which is proportional to the relative velocity of the target is indicated on a meter 19 connected to the output of the coincidence circuit. For a stationary target, the frequency of the coincidence pulses is equal to the recurrence frequency of the system and such pulses are eliminated by the filter 17. The receiver 9 is blocked during transmission periods by the circuit 7 and the echoes from a single target are selected by gating the receiver with the output from the phase-shifter 29 and pulse generator 31. In order to produce a measurable coincidence frequency when the target is an aircraft, the recurrence frequency must be very high, e.g. 10 mc/s., but a lower recurrence frequency may be employed in which case the frequency of the oscillations from which the auxiliary pulses are derived is multiplied in the circuit 25 ; the recurrence frequency of the echo pulses may also be multiplied, Fig. 2 (not shown). The outputs from the auxiliary and receiver channels may be shaped to any desired waveform before combining them.

Title: Vibrating string transducer devices and systems for employing the same
Inventor: HOLMES PAUL J
IPC: G01P15/10
Filed: 1959-01-23
Abstract: 907,240. Measuring electrically. BORGWARNER CORPORATION. Jan. 23, 1959, No. 2649/59. Class 40 (1). In apparatus for measuring acceleration comprising an inertia mass 46 supported on a diaphragm 48 and attached to two substantially similar conductive strings 12, 14 which pass between the poles of permanent magnets 60, 62 and 68 and are maintained vibrating at their natural frequency, whereby any difference in frequency is indicative of the force acting on mass 46, e.g. due to acceleration, a linear relationship between frequency difference and acceleration is produced by keeping the sum of the two vibrating frequencies constant. As shown, the strings 12, 14 are maintained vibrating by amplifiers 16, 18 respectively, the vibrating frequencies being combined at 32 and their difference selected by a low-pass filter 33 for indication on a meter 34. With no force acting on mass 46, string 12 will vibrate at twice the frequency of string 14, because of the double magnet 60, 62; hence the difference in frequency will increase or decrease depending on the direction of the acceleration or force applied to mass 46. The frequency of the output from amplifier 18 is also doubled at 22 and mixed again at 20 with that from amplifier 16, the sum of the two frequencies being selected by band-pass filter 24 and compared with a constant reference frequency signal from oscillator 28 to give an error voltage when they differ, which is amplified at 30 and fed to an electromagnet 70 acting on the support 66 for one end of the wire 14, causing the stress in both wires to rise until the sum of the two vibrating frequencies is again equal to that of the oscillator 28. The system automatically compensates for variations due to e.g. changes in temperature. In an alternative arrangement the output current from amplifier 30 is fed through a heating coil to increase the stress in wires 12, 14, or directly through the wires to heat them. In a modified usage the change in stress in the wires 12, 14 is produced by a difference in fluid pressure on opposite sides of the diaphragm 48, the pressure difference being indicated on meter 34. Specification 880,361 is referred to.
