Title: Spurious signal suppressor for military IR detector - detects cause of perturbation and subsequently reduces field of image automatically (IT 31.7.80)
IPC: G01S3/781
Filed: 1969-05-22
Abstract: The infra-red detector includes a rotating prism (1) on whose surface radiation falls. This is reflected towards a mirror (2) which splits radiation according to wavelength. The visible light passes through this mirror to an objective lens (3) which focusses it on to a detector (4). The IR is reflected by the mirror to pass through an objective lens (5) to an IR detector (6). The rotation of the prism enables a wide field of view to be scanned. In order to distinguish between enemy aircraft etc. and natural objects, the signals detected in the two ranges of the spectrum are compared. Enemy aircraft offer good contrast in the IR spectrum, but are camouflaged in the visible spectrum and therefore offer little contrast. Natural objects - clouds, fires, etc. offer contrast both in the IR spectrum, and the visible spectrum.

Title: IC engine with strata charge - hydrogen is injected into ante chamber and ignited
IPC: F02B17/00
Filed: 1974-02-21
Abstract: A weak fuel mixture with a ratio of 22:1 is drawn into the combustion chamber via an inlet valve in the conventional manner. During the compression stroke, hydrogen is injected by a magnetically operated injector in the proximity of the spark plug. The spark ignites the hydrogen and the ensuing flame in turn ignites the weak mixture. The hydrogen injector nozzle is protected from the flame by a unit having an axial boring contg. a ball with radial and axial play. The boring is provided with a plate to retain the ball. The injection pressure pushed the ball onto the retainer plate and allows hydrogen to enter the combustion or ante chamber and the combustion gas pressure holds the ball to the jet nozzle.

Abstract: The frequency multiplier has slow and rapid frequency generators, the rapid generator giving a frequency 360 times the frequency of the slow generator. Each input pulse returns to zero the two generators. A chosen parameter of the rapid generator returns this generator to zero each time this chosen parameter reaches the value corresponding to the same chosen parameter of the slow generator at the moment of arrival of the preceding input pulse. The zero resetting of the rapid generator supplies frequency output pulses 360 times the frequency of the input pulses.

Abstract: A frame (1) mounted on the front of a tractor has an overhead cross-beam adjustable for height by a hydraulic jack. On one side of the crossbeam is a pair of lifting arms which gradually raise up the vine shoots as the tractor proceeds. The edges of the arms are clad with rubber sleeves to prevent damage to the shoots. A counterweight on the other side of the cross-beam balances the machine. Once the shoots are raised up they are held in this position by wires unrolling from reels on the frame on each side of the vine row. The wires are kept taut by tensioning pulleys. A stapler clips the wires together at suitable intervals.

IPC: H02J7/02
Filed: 1974-06-24
Abstract: 1434692 Dynamo-electric machines; charging batteries McCULLOCH CORP 17 June 1974 [11 July 1973] 26674/74 Headings H2A and H2H In a hand tool comprising a commutator electric motor fed from a battery, the battery may be recharged by employing the motor windings as a transformer. In the embodiments disclosed, the field windings are connected to an A.C. supply and the armature winding charges the battery through a rectifier 24, Figs. 2 and 3 (both not shown). Fig. 2 illustrates a compound D.C. motor in which the armature and series field windings are employed as the secondary of a transformer. The brushes have to be shifted by half the polepitch. The brushes may be physically rotated. Alternatively, the motor may include four brushes (two pole motor, Fig. 3). Relays then determine which set of brushes are operational at any given time to set the machine for motoring or transforming mode. Fig. 7 illustrates a rocker arrangement comprising pivoted arms 112, 146 having contacts at both ends. A manually operable arm 130 pivotable about the shaft axis, determines which set of contacts engage the armature. Springs 124, 156 normally bias the arms 112, 146 such that brushes 110, 150 contact the armature for motoring mode. Arm 130 embraces a reel 170 carrying a cable 174 having a connector 176 for connection to an A.C. supply. Fig. 9 (not shown) illustrates a pivoted arm including a solenoid (204) which carries the armature current and so, in motoring mode, increases the brush pressure as the load increases. Fig. 10 (not shown) illustrates a permanent magnet system serving the same purpose.

Used for axial feeding, and rotating pierced blanks through 90 degrees, on pilger rolling mills for mfg. seamless tubes, the rolling bearing reducing the resistance to motion of the revolving rod by min. 70%, thus increasing the speed of feeding the mill and raising output.

Title: Automatic exposure controller for reproduction camera - has drive moving photocell over image plane
IPC: G03B27/80
Filed: 1975-01-17
Abstract: Automatic exposure time regulator for a reproduction camera is controlled by photocells on a movable holder which has a drive such that it is set in motion at the start of an exposure, to move the holder and photocell at a constant speed along and in front of the image plane for a photographic film or material. The regulator elements for regulation of the exposure time depend on the max. light intensity sensed by the photocell at any point in the image plane. Preferably the drive is such that the photocell makes a single scan of the image surface for each exposure. Regulation thus depends on the total light falling on the image plane.
