Abstract: Abstract of the Disclosure Devices and methods are disclosed for remote measurement of temperature (and velocity) profiles in a fluid medium (i.e., the atmosphere and/or oceans). Each device, herein called an echometer, and method are capable of providing remote measurements of temperature through the use of propagated waves (i.e., acoustic or electromagnetic waves) and interferometric principles.  By use of Doppler processing, simul-taneous measurement can be made of three-dimensional velocities at the same points in space to enable remote measurement of heat fluxes in the atmosphere or ocean.  The waves to be propagated are formed and then transmitted from a transmitting array to form a pattern of constructive interference fringes and reflected (or scattered) waves are received from predetermined points in the constructive interference fringes at a receiver where an analog signal indica-tive of the reflected waves is formed and the mean phase thereof sampled to form a digital signal that is processed to determine therefrom temperature changes or absolute temperature measurements at predetermined points spaced from the transmitting array and receiver.

Abstract: ABSTRACT OF THE DISCLOSURE:           There is provided an industrial microwave furnace comprising a metal casing subdivided into three adjacent compartments by partitions having each an opening in an upper part thereof. The two outer compartments each include a number of microwave generators and are each pressurized by a flow of cool air from an associated air fan. The micro-wave generators are disposed opposite the openings in the partitions such that warm air resulting from cooling of the microwave generators by the flow of cool air is directed through the openings into the middle compartment which forms a microwave applicator section. The industrial micro-wave furnace further comprises a plurality of waveguides arranged on the walls of the casing and a plurality of radiators for coupling the microwave energy from the micro-wave generators in the waveguides and for coupling the micro-wave energy from the waveguides into the middle applicator compartment. The radiators are evenly distributed along the waveguides so as to create a constant electric field over the cross-section of the middle applicator compartment, thereby to result in a constant heating over the cross-section of the middle applicator compartment and in a maximum microwave energy coupled into the middle applicator compartment.

Abstract: Abstract The steam gernerator comprises a first vertical flue (10) consisting of tube banks (12, 13) welded in sealing-tight relationship.  It also comprises a second vertical flue (11) adjacent the first flue and a transverse flue (15) connecting the vertical flues in their top zone.  In order to take the weights of the           of the tube banks (12, 13 and 12', 14 ) of the first and second vertical flues a bearer system (7 and 8 respectively) is provided for each vertical flue in the region of the height just below the transverse flue (15) and is connected to the boiler supporting structure (2, 5) just below the transverse flue.      As a result, the steam generator construction is simplified, since the bearer tubes otherwise required and extending form the back wall of the first vertical flue and the front wall of the second vertical flue and through the transverse flue are eliminated.

Abstract: Method and apparatus for accelerating the drying and/or curing of filler material, primer and top-coatings in connection with touch-up work on car bodies wherein grinding, filling and spraying are accomplished in one and the same booth, whereupon a carrier containing infra-red heat radiators and/or heating-elements and/or nozzles is traversed over the car, whereby controlled heat-energy is supplied to the surface accelerating drying and/or curing process of the surface treatment material. For supplying sufficient heatenergy to the front and rear parts of the car, special reflectors are located in front of and behind the car for reflecting heat-radiation from the carrier. The carrier is divided into sections with controlled, separate energy-supply and ventilation-air both when heat-transfer is accomplished and when the carrier is located in a parking recess, from which ventilation-air passes via specially designed slots out into the booth. The ventilation-air is conducted along the infra-red-radiators and/or heating-elements/air nozzles in a laminar air flow towards the car. The ventilation air is ventilated out from the sides and the floor of the booth. The travel of the carrier over the car body and the energization of the heating is programmed with respect to a given body configuration and with respect to the touch-up work being done in order to minimize wasteful use of energy to otherwise heat parts which do not require to be heated.

The apparatus provides an improvement in a projection system for projecting light along an illuminating path to a viewing screen.          The improvement is in a form an image forming system which can be manipulated to adjust the contrast between juxtaposed areas of the projected light distribution image.  The apparatus comprises a source of substantially unpolarized light arranged to project along an illuminating path and image forming means and a contrast adjustment means.  The image forming means has at least two discrete light transmitting zones disposed in the illuminating path to receive and transmit primary and secondary illuminating light beams respectively.  The first zone has juxtaposed areas of sharply contrasting translucence whereby the primary illuminating light beam emanating from the first zone forms a primary image which has sharply contrasting image areas.  The contrast adjustment means is disposed in the illuminating path for receiving the primary and secondary light illuminating beams and is adjustable to vary the ratio of the light intensity of the primary and secondary illuminating light beams transmitted therethrough to vary the contrast of the light distribution image.  A Maddox rod is disposed in the illuminating path to receive the polarized light emanating from the contrast adjustment means to smear the image formed thereby prior to projection on to a viewing screen.        - l -

Abstract: ABSTRACT         A receiver comprises an FET frequency mixer having first and second gate electrodes, a local oscillator, a first AGC amplifier and a second AGC amplifier.  The first AGC amplifier is coupled to the first gate electrode for varying the gain of a high frequency signal in response to a control signal and the second AGC amplifier is coupled to the second gate electrode for varying the gain of the output signal of the local oscillator.  A generator coupled to the output of the FET mixer generates the control signal.  By controlling the gain of the second AGC amplifier, the IF signal output level of the FET mixer is made controllable and, moreover, the range in which the conversion gain MGT is equivalently controllable can be expanded to be as wide as the gain control range of the local AGC amplifier.  In this way the dynamic range of the FET mixer can be equivalently expanded to equal the AGC dynamic range of the second AGC amplifier.

Abstract: ABSTRACT:           The invention relates to a method of and a system for remote control of individual electronic equipments (R), which are spread out across a large geographical area.  In particular it concerns activation of radio transmitters spread over the water surface and cooperating with hydro-phones for taking up sound waves from submarines in order to localize these submarines.  In order to achieve selec-tive activation of the electronic equipments, electromag-netic waves or sound waves are transmitted with given relative time positions from at least three fixed stations (I, II, III) having known geographical positions.  In each electronic equipment the waves are received and compared as regards their relative time positions at reception, activation of an equipment taking place only if a given criterion as regards the mutual time positions is ful-filled.  Hereby activation of equipments will take place only within a given small zone of the large area.  The position of the small zone is determined by the relative time positions of the transmitted waves, which can be varied in order to select different zones.
