Title: Apparatus for the alignment of a symmetrical object in relation to a given line
IPC: G01C11/00
Filed: 1961-11-07
Abstract: 960,478. Gauging position by television. FERNSEH G.m.b.H. Nov. 7, 1961 [Nov. 8, 1960], No. 39865/61. Heading H4F. Apparatus for determining the alignment of a symmetrical object movable in a first plane in relation to a given line, e.g. a ship 1, Fig. 1, which is movable in a dry dock 2 in relation to a line 8 of keel plates 5 on to which it must subsequently settle, comprises two television cameras 6, 7 arranged to view the object, or a further object characterizing its position, along optical axes symmetrically inclined at equal angles less than a right-angle with respect to a plane containing line 8 and perpendicular to the first plane, together with means whereby the video signals developed by the cameras are displayed as images on one or more television monitors provided with means for indicating the position of the images which correspond the desired position of the object in relation to the line. Thus in Fig. 2 the two views of the bows of the ship are displayed on one common monitor the images intersecting on a line 11 which becomes aligned with a pointer 12 when the ship is correctly positioned over the line of keel plates. In another arrangement, Figs. 6 and 7 (not shown), the signals from the two cameras are displayed on separate monitors. One of the images may be laterally and/or vertically inverted, Figs. 8-11 (not shown). A further pair of cameras 13, 14 may be employed to view the stern of the ship. The images from all four cameras may be displayed on a common monitor, Figs. 4 and 5 (not shown). The means for indicating the correct positions of the images may comprise scale marks produced electronically. When the ship is almost aligned correctly, the magnification of the images may be increased, either by the change of camera lenses or by changing the horizontal deflection amplitude in the cameras or monitors.

Abstract: 1502430 Visual range estimating DEFENCE SECRETARY OF STATE FOR 11 Sept 1975 [13 Sept 1974] 40127/74 Heading G1A Visual range estimating apparatus comprises: light sources 1-n each including a filament, e.g. (n-2) Fig. 2 and a photo-transistor 30 mounted in a protective enclosure 9; respective switching circuits 31-34 each adjacent a light source; and a control circuit 4 including a D.C. source 21-27 and means 5 for applying a current to a selected switching circuit to switch off the associated source. The sources 1-n Fig. 1, spaced out e.g. along a runway, are viewed from an observation point to determine the visual range by identifying the farthest visible source (e.g. (n-2) just within a limit of visibility 8). To enable the sources to be easily identified and distinguished from other sources, each filament is connected to normallymade contacts 31a of a relay 31 operable from a control unit 4 at the observation point by means of a selector 5 in series with a push-button 6, whereby each filament in turn can be switched off, until the last filament seen to blink is regarded as being at the visual limit. In order that a lamp which has failed to blink because it is faulty shall not be mistakenly supposed to be out of range, an integrity lamp 7 lights up on pressing the button 6, but only if the selected filament is serviceable. The control unit Fig. 2 comprises a constantcurrent source with over-voltage protection 20-28 supplying, via the integrity lamp 7 and the button 6, the selector 5 shown at the (n-2)th position. Pressure on the button 6 supplies current through the integrity lamp 7 to the relay 31, only provided that the series photo-transistor 30 is rendered conductive by a serviceable filament (n-2). Contacts 31a then open to extinguish the filament, but contacts 31b close to hold the circuit through the integrity lamp 7 until the button 6 is released. The selector 5 has an (n+1)th TEST position for testing the integrity lamp 7 itself.

Title: Apparatus for controlling vapour deposition in a vacuum
Inventor: BATH HUGH HENRY ANTHONY
IPC: C23C14/54
Filed: 1963-10-16
Abstract: In apparatus for monitoring the thickness of a film being vapour-deposited on a substrate, a quartz crystal 2, Fig. 1, located in the evaporation <PICT:1073293/C6-C7/1> chamber 1 constitutes the frequency-determining element of an oscillator 3.  The resonant frequency of cystal 2, and hence the frequency of oscillation of oscillator 3, varies with the thickness of the deposited film on the crystal.  The output of oscillator 3 is compared frequency-wise with that of a crystal-controlled fixed-frequency reference oscillator 4 in a diode mixer 5 the output of which is compared with that of a variable-frequency reference oscillator 6 in a second mixer 7. The output of mixer 7 is squared by a pulse-shaping circuit 8 before being fed to a frequency-discriminator 9 whose D.C. output (a) operates a meter 10 to indicate film thickness; and (b) is differentiated in a rate-meter 11 to indicate rate of deposition. The voltage applied to meter 10 is continuously compared with the output of a pre-set potentiometer, and a null-detecting switch operates an electromagnetic shutter to interrupt the flow of evaporant when a predetermined thickness is reached.  Retroactive control of deposition rate.  Fig. 2 (not shown). A.D.C. voltage derived from the rate-meter (11) is compared (at 12) with a reference voltage.  The error signal is amplified (at 13) and used to determine the level at which current supplied to an evaporator-heater (20) is held by a stabilizer (15).  The output of the stabilizer (15) is fed to a phase-shift circuit (16) to determine the proportion of each half-cycle of current supplied via a transformer (19) which is allowed by a pair of silicon controlled rectifiers (17) to pass to the heater (20).  The heater current is continuously monitored by a current transformer (18) which feeds back to the stabilizer (15).  A timer (14) may initially be connected to the stabilizer (15) to control the time and current levels of a preliminary degassing cycle.

Abstract: 898,959. Refrigerating. GENERAL ELECTRIC CO. Dec. 19, 1958 [Dec. 20, 1957(2)], No. 41034/58. Addition to 895,227. Class 29 In the refrigerating system of the main invention refrigerant is prevented from reaching the evaporator during defrosting. As shown, when valve 20 is opened, hot gas from the compressor and any liquid in the condenser passes to conduit 22 through pipe 18 and rapidly heats that region of the evaporator plate; this is detected by thermal bulb 51 which actuates control 50 to close valve 27 in the inlet to condenser 2. Bulb 51 may be located on the suction pipe 5. In a modification, Fig. 2 (not shown), hot gas pipe 18 is led in heat exchange with the condenser outlet or the first part of the main capillary restrictor so that, when the defrosting valve is opened, the hot gas generates vapour in the condenser outlet to block the restrictor and prevent the supply of liquid refrigerant to the evaporator.
