Patent GB-747147-A (GB)
Title: Control system for radio position locator
IPC: G01S13/78
Filed: 1954-04-12
Abstract: 747,147. Radar. HAZELTINE CORPORATION. April 12, 1954 [May 13, 1953], No. 10668/64. Class 40 (7). This Specification describes the main embodiment of Specification 747,146 and explains in greater detail the working of the control circuit for changing over from searching to tracking operation and vice versa. This control circuit includes a memory arrangement to prevent searching recommencing immediately on the non-arrival of reply pulses and the circuit is such that the memory period is dependent on the length of time that tracking has been taking place. This prevents the arrival of a spurious pulse pair which happens to have the correct spacing from delaying searching for an unneccessarily long period. As described in connection with the abovementioned Specification the arrival of a correctly spaced pulse pair causes a negative pulse to be fed to the control circuit over capacitor 69. This pulse is passed through diode 70 and applied to the grid of valve 66 to render the latter non-conductive. Due to the action of capacitor 72 valve 66 is maintained non-conductive, or substantially so, for a period longer than the duration of the applied negative pulse. The capacitor's charge does not leak away through resistors 67 and 68 sufficiently to allow the potential at Y to rise to a value at which gas-filled tube 76 will conduct before the next pair of reply pulses are due to be received. Searching is suspended and tracking possible as long as tube 66 is non- conductive and a potential of - C is applied through resistors 57, 58 and 59 to render diode 54 non-conductive except when tracking pulses are applied. If no further negative pulse is applied over capacitor 69 the potential of the grid of valve 66 soon rises to a value at which, the valve conducts sufficiently to raise the potential at Y and enable the tube 76 to strike. When this happens a positive signal of + B<SP>1</SP> is applied to the anode of diode 54 and searching recommences. When a series of reply pulse pairs are received and the system successfully tracks on these signals a steady series of negative pulses are applied to the control circuit over capacitor 69. When passed by diode 70 these serve not only to maintain the negative charge on capacitor 72 but to gradually build up a negative charge on relatively large capacitor 74 fed through resistor 73. Thus, after a period of tracking, searching does not recommence until the charges on both capacitors 72 and 74 leak away. This memory period avoids the loss of tracking which would otherwise result from the non-reception, due to adverse conditions, of a few of the reply pulse pairs.

[Class 44.] A revolving-barrel pintumbler lock is provided with a sleeve 4 or plate fitted on the periphery of the barrel 2 and displaceable a certain amount with respect thereto but normally always secured thereto by the pin tumblers 8, which in the unlocking position have their division line 10 in register with the outer periphery of the sleeve or plate. Should the barrel 2 have been released by a picking operation to bring the division line of the pins in register with the inner periphery of the sleeve or plate, the barrel can only be turned a small amount since the sleeve or plate will be held by the outer parts of the pin tumblers : this movement is insufficient to withdraw the lock bolt (not shown), which is actuated by the link 11. The barrel 2 and sleeve 4 are shown connected axially by a bayonet joint 5 and are formed respectively with shoulders 6, 7, by which they are retained in the casing 1. The bolt operating link 11 has aT-end 13 secured to the sleeve by a split plate 15, Fig. 2, inserted in a transverse slot. The relative movement of the barrel is taken up when its bayonet lugs 5 engage the T-end 13 of the link 11, Fig. 3, which is held rigid with the sleeve 4 by the split plate 15. With the plate construction, Figs. 5-8 (not shown), the relative movement is taken up when the plate edges abut on the edges of the peripheral recess on the barrel in which they are mounted. The tumbler pin bores may be slightly conical while the rear bores may be of greater diameter. A number of plates or of sleeves may be arranged side by side or on top of one another.
