Patent GB-2175172-A (GB)
Title: Video cameras
Inventor: CHILDS IAN
IPC: H04N5/235
Filed: 1986-04-29
Abstract: An improvement for a video camera comprises means 10 for restricting the effective exposure of photo-sensitive elements 32 of the camera to scene light, in order to substantially eliminate flicker arising from differences between a camera field rate and the rate of illumination variation due to mains frequency. The exposure is related to the period of illumination variation during each field. In one embodiment the restricting means consist of a rotating shutter 10 located between a camera lens 28 and the photo-sensitive elements 32 of the camera. In another embodiment the restricting means consist of an electronic signal blocking device. The improvement has applications on both tube and charge-coupled-device cameras. <IMAGE>
Patent GB-2177566-A (GB)
Title: Scanning radar systems
Inventor: MOTKIN DAVID LOUIS
IPC: G01S13/42
Filed: 1986-06-13
Abstract: A radar system comprises a transmitter in which each transmitted pulse is divided into a number of sub-pulses; two in the preferred embodiment. The sub-pulses are arranged to have different frequencies (f1, f2) and the azimuth/frequency sensitivity of the horizontal elements of the system antenna causes the sub-pulses to be radiated at different azimuths (22, 24). Thus, each transmitted pulse illuminates simultaneously a number of azimuths corresponding to the number of sub-pulses. In this manner, an increase in the number of pulses directed towards a potential target in each antenna rotation from more than one azimuth direction and within the same pulse repetition interval may be achieved.

Title: Photoelectric smoke detectors
Inventor: KIMURA TETSUO
IPC: G08B17/10
Filed: 1986-06-25
Abstract: A photoelectric smoke detector includes a light source (L), a photosensor (P), a holder (H) for holding the light source and the photosensor, and a dark box (A) housing the light source and the photosensor. The light source (L) and the photosensor (P) define a smoke detection region (D) therebetween. The photoelectric smoke detector allows the photosensor to receive light rays emitted from the light source and scattered by smoke, thereby detecting the presence of smoke. The detector further includes a light scattering member (S) arranged outside the smoke detection region (D) to adjust a light scattering level of external light, from outside the dark box (A). <IMAGE>

Title: Quality control in wire processing
Inventor: DUSEL ROBERT O
IPC: G01N21/892
Filed: 1986-10-03
Abstract: Wire processing apparatus employs a conveyor for transporting wire segments to a series of wire processing machines which strip insulation from the wire segment ends and then subsequently attach electric terminals to the stripped ends. A quality control device located between the insulation stripper machine and the terminal attachment machine inspects each stripped end and, if it does not meet desired tolerances, sends signals which prevent the terminal attachment machine from operating upon the defective stripped end as the conveyor moves the wire segment therepast. The quality control device comprises an illuminated field at which the stripped end momentarily stops, an optical lens opposite the illuminated field for providing an optical image of the stripped end, and a converter for converting the optical image to an electronic image signal. Solid state electronic circuits compare the image signal to a reference signal, provide an error signal if the stripped end is defective and store the error signal in a memory circuit. The error signal, if present, is recalled from the memory at the appropriate time and converted to an output signal which prevents the downstream terminal attachment machine from operating on the defective wire end.

Title: Radar altimeter systems
Inventor: ANDREWS FRANK PHILIP
IPC: G01S13/88
Filed: 1988-10-05
Abstract: An aircraft microwave altimeter system is dual purpose and has a threshold detector (8) with two parallel channels (13 and 14) that provide two sets of output signals at two different levels of sensitivity. The signals at the higher sensitivity are supplied to a display (30) whereas those at the lower sensitivity are supplied to a navigation system (31). A comparator (50) indicates a fault in the system if the two sets of output signals differ by more than a predetermined amount. The high sensitivity channel - using a low threshold detector 15 - enables a pilot to view all obstacles on his display 30, whilst the low sensitivity channel - using a high threshold detector 16 - allows a terrain avoidance navigation system 31 to be fed with signals indicating only large, significant, obstacles. <IMAGE>

Title: Patterned film deposition from perforated
Inventor: WILLIAMSON ROGER JAMES
IPC: C23C14/04
Filed: 1988-11-10
Abstract: A surface film is deposited on a substrate surface from an adjacent sputter source on which an ion beam is directed, the source comprising a perforated laminar body, e.g. a gauze. The beam is traversed across the source so as to provide a corresponding pattern of deposited material on the substrate. The deposited film may comprise a metal eg aluminium, silver or gold or alloy, or an inorganic compound material such as a high temperature superconductor, such as a yttrium barium copper mixed oxide. The substrate may be a quartz crystal or a photolithographic mask. As illustrated in Fig 1 an ion gun 15 is mounted on the vacuum chamber and is directed to the spatter source (14, Fig 2) comprising a perforated laminar body which is supported adjacent the substrate 12. The ion beam is steered to the desired position on the spatter source via deflection electrodes 19 and as the ion beam is steered or traversed across the source the ions impinge on its body surface within the openings and this causes spattering of material from the region of the impact. Each opening functions as a point source from which material is spattered when irradiated by the ion beam and the substrate is shielded from direct exposure to the ion beam. The configuration of the patterned deposit is determined by the manner in which the ion beam is directed relative to the source body 14, while the definition of the pattern is determined by the cross-sectioned area of the openings and by the spacing between the source body 14 and the substrate. <IMAGE>

A wattmeter may be used as the measuring instrument. Figs. 1-3 (not shown) relate to known adjustable Miller integrators, using valves or transistors.

Title: Measurement of the temperature of a body in a vacuum
Inventor: NEUHAUS DIETMAR
IPC: G01J5/04
Filed: 1990-05-04
Abstract: The accurate measurement of the temperature of a body e.g. of molten metal (11) arranged in a vacuum can be hindered by the deposition of material from the body on mirrors, windows and other optical means so that the radiation is partially absorbed on its way to a temperature measuring pyrometer (12). For preventing vapour deposition on such optical means, a vapour filter (17) having a rotating vane wheel (18) is arranged between the body and the pyrometer (12). The radiation passes through the gaps between the vanes (28). Molecules of material which leave the body as a vapour are caught by the vanes. Accordingly, a mirror (22) behind the filter (17) is kept free of undesirable material and transmits radiation to the pyrometer (12).
