Abstract: Abstract of the Disclosure A direction control valve for controlling a reversible hydraulic actuator includes a valve body in which a pair of valve stems and a pair of float control pistons, respectively axially aligned with the valve stems, are reciprocally mounted.  To establish a float condition in the actuator, the pair of valve stems are simultaneously shifted to respective active positions by engagement of the pair of float-control pistons to which pressure fluid is routed upon selective energization of a solenoid-operated valve by manually closing a first normally open switch.  A second normally open switch is connected in parallel with the first switch and is closed by a switch-control piston mounted in the valve body between and in fluid communication with the float-control pistons and shiftable concurrent therewith whereby the manually operable switch may be released without effecting de-energization of the solenoid-operated valve.  A control rod is rockably mounted in the valve body for selective movement to opposite sides of a neutral position for respectively initiating independent shifting of the pair of valve stems to their active positions for respectively effecting extend and retract conditions in the actuator.  A cam is fixed to the control rod and is operable, when the control valve is in its float-effecting condition and the control rod is moved from its neutral position, to move the switch-control piston to release the second switch and de-energize the solenoid-operated valve whereby the control valve is released from its float effecting condition.

Abstract: ABSTRACT OF THE DISCLOSURE     A wide field of view is scanned to determine spectral and positional information of a point source of optical radiation.  The wide field of view is optically scanned by a scanner having an instantaneous narrow field of view to sequentially direct radiation from successive scanned portions of the field onto a detector included in an image plane of radiation.  An optical dispersion means for the radiation is provided in a first optical path that includes the scanning means and the detector. A second optical path between the source and detector includes the scanning means, but does not include the dispersion means.  The dispersion means and the scanning means cause a convolution of spectral energy from the source in the image plane, resulting in a displacement of the relative occurrence times, during a scan, of a wavelength of the radiation as it impinges on the image plane via the two optical paths.  A processing cir-cuit measures the displacement, amplitude and spectral content to provide a visual indication of the angular position of the radiation source.  The use of two optical channels also provides a simplified cross correlation system for comparision of spectral sources with respect to a reference.

The bead becomes an integral part of the watch case assembly, yet disassembly does not impair the effectiveness of the bead upon subsequent reassembly.
Patent CA-1084606-A (CA)
Inventor: LARSON ROGER G
IPC: G01F23/26
Filed: 1979-01-03
Granted: 1980-08-26
Abstract: ABSTRACT         The present invention relates to apparatus for determining the liquid level in a non-metallic tank. Measurement means for determining the liquid level in liquid containing tanks are usually positioned within the tank and directly contact the surface of the liquid.  Such de-vices, however, can cause a malfunction of the measuring device and leads to sanitary problems and unpleasant odors. Metal electrodes, probes, or plates can be mounted on the outside of the tank, which plates are insulated from the liquid therein in a manner such that the capacitance between the plates varies as a function of the level of the liquid in the tank. However, after the tank contents will tend to adhere to the walls of the tank, causing an incorrectly high reading. The present invention solves these problems in manner unknown heretofore. With the present measuring means, a pair of parallel plates are secured to the outside of the tank to avoid contact with the liquid inside of the tank.  The plates have a generally vertical orientation so that as the liquid rises in the tank, an increasing area of the plates is adjacent to the liquid.  The change in capaci-tance between the plates as a function of liquid level is utilized to generate an electrical signal indicative of liquid level.  The problems caused by highly viscous liquids coating the inside surface of the tank and yielding false readings are solved by utilizing a high frequency driving signal.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for heating or cooking food is described which comprises a plate forming the hot horizontal surface on which the food to be cooked is placed, a heating source underlying the plate and a cover above said plate which defines a mainly closed space. The plate has high thermal conductivity. Preferably, the plate has a raised edge effective to circumscribe and define a space for locating and containing the food.  The plate may be inverted and the apparatus may be used as an open grill. In this arrangement heat is transmitted by conduction. The plate is provided with essentially vertically extending passages located, in the perimetral  parts of the plate, in section in vertical planes, in such a way that the lower mouth or inlet of said passages fully communicates with the space underlying the plate so that active circulation of superheated air is established between the space underlying the plate and the space above the plate and defined in the inside of said cover. When the plate is inverted, circulation is prevented or at least strongly hindered.  Heat given off by the heat source is trans-mitted, substantially completely, through the planar portion of the plate.
