Title: Radiation tracking devices
IPC: G01S3/783
Filed: 1968-04-03
Abstract: 1,219,172. Photoelectric direction finding. KOLLSMAN INSTRUMENT CORP. 3 April, 1968 [6 April, 1967], No. 15930/68. Heading H4D. [Also in Division H1] The Specification describes a star or similar radiation source tracker, comprising a telescope objective lens 11, Fig. 1, receiving light from the radiation source and a rotating wedge 14 causing the image of the source to describe a circle on a photo-detector 13. Error position signals produced by the photo-detector 13 cause a servo system 16 to realign the telescope such that the image circles about the axis of the telescope. The photo-detector 13, Fig. 2, comprises a square monocrystalline silicon wafer initially of N-type conductivity. Four square surface regions of P-type conductivity 20, 21, 22, 23, are formed by diffusion, to produce four photo-sensitive planar junctions. Digitated aluminium electrodes 25, 26, 27, 28 are formed for each junction, the space between adjacent fingers of an electrode being equal to the width of each finger, and the diameter of the scanning circle 41 of the image being approximately equal to the scan of a finger plus a space width. The image scans at 100 revs./sec. and the output from an electrode, e.g. 26, is of pulsed form having components at 100 p.p.s. or 200 p.p.s. depending on the position of the scan. With the scan at the desired centre of the photodetector each electrode gives an output having 100 p.p.s. components. Thus by means of suitable processing circuitry detecting the output of each electrode and which electrodes are producing an output, azimuth and altitude servo correction signals can be produced.

Abstract: 117,555. Thomas, W., and Roderick, L. J. Nov. 10, 1917. Pickling.-In pickling-apparatus in which certain parts are reciprocated vertically by steam power, the steam cylinder 4, the piston 5 of which is connected to the parts to be reciprocated, is formed with a port 6 connected by a pipe 7 with a valve-casing 8 containing a distributing valve 3 for controlling the reciprocation. A vertically-moving member 1 engages with a rod 2 and lowers the valve 3 to admit steam through a port 11 to raise the piston 5. As soon as the port 6 is uncovered, the steam under the piston 5 passes through the pipe 7 to the lower end of the valve 3 which is raised and allows the steam to exhaust through a port 12 and the piston 5 to fall, the operations being thus repeated. In a modification, Fig. 2, the port 6 is connected by a pipe G to a cylinder C having a piston D which effects the movement of the distributing- valve B through a lever E. A valve 10 is provided to enable the piston 5 to make a full stroke when required.
