Abstract: 1331510 Synthesizing optical apertures G W STROKE 2 Dec 1970 [6 Dec 1969] 57325/70 Heading G2J [Also in Division H5] The spatial frequency transfer functions of large-aperture image forming devices are synthesized by forming with incoherent radiation a plurality of intermediate images of an object to be imaged, each intermediate image containing predetermined spatial frequency components of the object corresponding to components which would be transmitted by components of the desired large aperture device, and superposing the said images to form a final image including the frequency components of the different intermediate images. The aperture to be synthesized is simulated using at least two image forming elements which are small relative to the aperture being synthesized. The small elements o, n, are fixed in relation to each other. Preferably a plurality of such elements are used either simultaneously or successively, each having different spacings and orientations. Deisrably one element of each set is common to all. The recording means may be a single camera, or a plurality of cameras; the image elements being fixedly mounted relative to the camera or movable relative thereto Fig.8 (not shown). The spacing and orientation of the elements o, n may be controlled. In an alternative embodiment the aperture is synthesized using a fixed grating G 0  at one extremity and a grating G 1  movable from a position adjacent G 0  to the other extremity (Fig.11). The number of elements used is predetermined to give the desired spatial frequencies which will form the desired image. The elemental images may be recorded separately and successively and then superposed to give the final image, or the intermediate images may be successively recorded in superposition on a single photographic film or plate. To remove unwanted redundancy the individual intermediate image records, may be subjected to a spatial filtering process Fig.12 (not shown), using a spatial low frequency redundancy attenuating filter.

Abstract: 1,113,570. Ship's davits for lifting pilot ladders or lift platforms. WELIN A.B. 29 Dec., 1966 [29 Dec., 1965 (2)], No. 58136/66. Headings B8B and B8H. [Also in Division A6] A davit for raising and lowering a ship's pilot ladder or a lift platform comprises a U-shaped frame 1, 2, Fig. 1, pivoted to the deck of the ship by pins 4 and brackets 5. In operation a ladder 10, Fig. 2, with grooved wheels 12 which run on rails 9 is placed on the davit where it is retained by members 25. A cable 20 is passed from a central winch round pulleys 18, 17 and attached to lugs 19. When the cable 20 has been pulled taut the davit is released from the deck by withdrawing a pin 26 and the cable is paid out. This allows clockwise pivoting of the davit until legs 13 rest on the side of the ship. Further paying out of the cable lowers the ladder with the wheels 12 resting on the side. A limit switch 21 stops the winch when the top step of the ladder contacts it during raising thereof. Fig. 5 shows an embodiment using an articulated ladder, the winch 24 is mounted adjacent the davit which is pivoted on elongated brackets 5. The davit may be used to raise a lift-platform, Fig. 6 (not shown). The base 1 of the davit, Fig. 1, forms a continuation of the ship's railing 28 when in the stowed position.

Filed: 1972-12-18
Abstract: 1412449 Radiation pyrometers SENSORS Inc 18 Dec 1972 [21 Dec 1971] 58252/72 Heading G1A In an IR pyrometer having a detector producing an electrical signal proportional to the difference between the fourth powers of the absolute temperatures of the object and the detector, an independent sensor measures the absolute temperature of the detector to produce a signal which is raised to the fourth power and combined with the detector output to compensate for the detector temperature, the fourth root of the resulting signal being extracted to produce a signal linearly related to the temperature of the object. As shown. Fig. 1, IR radiation from an object 10 is incident on a thermopile 12 the output voltage of which is applied via amplifier 15 to a calibration control 17. The temperature of the detector is measured by a thermistor 20 arranged in a bridge circuit the output of which is applied to a summing amplifier 29 having a second input adjusted to remove the bridge resistance component resulting in an output linearly related to the detector temperature. This signal is raised to the fourth power by a device 32 comprising two squaring circuits in series, a diode function generator, or a log-antilog circuit. Alternatively the bridge circuit may be arranged to provide a linear approximation to the fourth power of the absolute temperature if the pyrometer is to be used over a restricted temperature range. A summing amplifier 39 combines the detector and fourth power temperature outputs to produce a signal proportional to the fourth power of the absolute temperature of the object. If the object is not a block body radiator compensation can be made by means of a calibrated emissivity adjustment potentiometer 36 which can be set in accordance with known values or by calibration using contact temperature measurements. The fourth root of the signal is then extracted by device 38 to produce a signal proportional to the absolute temperature which is applied to scaling amplifiers 40, 42 provided with suitable offset potentials to produce outputs proportional to the object temperature on the Celsius and Farenheit scales respectively. The output voltages may be used for process control and either may be selected for application to a digital meter 48 and to a recorder. Radiation may fall directly on the detector (Fig. 4) or may be focussed by means of a curved mirror (Fig. 2) or a lens (Fig. 3).

A card 60 is driven across a support 16 which is movable between a non-reading position and a reading position, and a stop 27 locates the card in the correct position for reading on the support and controls the card drive mechanism. A motor 3 rotates drive wheels 18, 19 when insertion of a card is detected by a switch 22 so that the card is driven up against the stop 27 to operate a switch 24 which causes a solenoid 4 to pivot a cam 12 and raise the support 16 towards a reading head 30. Raising of support 16 opens a switch 25 to de-energize motor 3 and causes stop 27 to be depressed below the card by an arm 36 spring 26 moving it to its rest position beneath the card. In response to data read from the card, a computer transmits an accept or reject command to lower the support and reenergize motor 3 in the forward or reverse direction. The apparatus may be used in a cash dispenser e.g. located in a street outside a bank.
