Abstract: To obtain better accuracy, it is known to modify the mechanical metered volume reading of the flow through a gas pipeline according to the gas laws, which incorporate the pressure and temperature parameters of the gas. The present invention samples those parameters with analog sensors and inputs them into an analog to digital converter. The digital output from the converter is employed to obtain a more accurate digital volume reading.

Abstract: A rotatable arm carrying an operative member is pivoted on a main housing (10) for movement between a rest position and a work position. A rotary shaft (28) is also journaled in the housing and can be driven by a wound spring (34) for rotary movement, which is transformed into a reciprocating, partial rotation of the arm by a linkage comprising meshing gears (18, 22) on the arm and on a fixed axis, and a crank and slotted link (24, 26, 30) between said shaft and the gears. A first and a second locking units (12, 14) are mounted stationarily with respect to the housing, each comprising a spring-biased pawl (40, 42) to engage the arm when it reaches said rest position and said work position, respectively, and each being releasable by an external control.

Abstract: Cartridges containing a prefabricated mixture of grated potato, onion, egg, farina, chopped chives, salt and pepper are the source for the raw potato pancakes, which are sliced off from the mixture to be fried in vegetable or artificial cooking oil. The raw potato pancakes are moved by two endless wire mesh belts through two consecutive skillets with cooking oil, the level of which is adjustable and automatically maintained, to be fried golden brown on both sides. At the end of the last wire mesh belt the fried potato pancakes slip over a slide directly onto serving plates for immediate consumption. The slicing and frying process happens fully automatically after entering the amount of servings into a microcomputer built-in to the apparatus housing.

Abstract: A rotating electric machine with an external rotor constituted by an asynchronous motor with a cage rotor, in which the rotor structure, instead of being mounted protrudingly on a stationary axial supporting element is supported thereon by means of two end shields mounted by means of respective bearings on an axial supporting element, which is monolithic with a stationary supporting shield.

Abstract: This invention relates to a keyboard cleaning device. More particularly, this invention relates to a device for cleaning upper and/or lateral surfaces of keyboard buttons or keys. In a first embodiment of the present invention, a key cleaner is comprised of a head structure having at least one convex cleaning substructure contoured to the top surface of a key of a data entry keyboard, a handle and means for attaching the handle to the head structure. Pursuant to a second embodiment of the present invention, the key cleaner is comprised of a head structure having at least one wedge-shaped cleaning substructure which is contoured to fit between the keys of a data entry keyboard and a handle attached to the head structure. Other embodiments are also described.

Abstract: A device for facilitating the attachment of decorative objects to an outer surface of a balloon comprises a plate-like base member, a first plate-like side wall member rigidly attached to the base member and oriented substantially perpendicularly thereto, and a second plate-like side wall member opposable to the first plate-like side wall member. Hinges pivotably secure the second plate-like side wall member to the base member so that the second plate-like side wall member can pivot from an open position for loading and unloading to a closed position wherein the second plate-like side wall member is opposed and substantially parallel to the first plate-like side wall member. A plurality of rods attached at one end to the first plate-like side wall member extend substantially parallel to the base member and to each other and cooperate with the base member, the first side wall member and the second side wall member to hold the balloon in the device.

Abstract: In a method for visually inspecting a sample through an objective lens of a microscope, a slide carrier attached to the microscope stage is automatically shiftable relative to a frame and to the stage along a predetermined meander path. A microscope slide and the slide carrier are provided with cooperating elements for positioning the slide at a predetermined position and orientation with respect to the carrier. The slide is further provided with a reference mark for enabling an automatic monitoring of the position of the slide relative to the frame of the carrier during an inspection of the slide. The x and y coordinates relative to the slide carrier frame of a detected microscopic object are recorded.

Abstract: A fluid system for controlling fluid temperatures and transferring heat from a thermal energy source such as a solar collector to point-of-need heat exchangers, remote from the collector from which heat is discharged for use. The fluid system blanket pressure, i.e., the pressure at the high point of the system, is maintained at a level such that the fluid vaporizes in the desired temperature operating range of the collector. The vapor collects in an accumulator that is connected in parallel in the heat transfer system with the collector. The accumulator serves to supply a regulated flow of vapor for motivating a vapor jet compressor-pump. The pump functions for the dual purposes of circulating the heat transfer fluid and as a vapor compressor for space cooling or the pumping of heat from the outside environment into the system to supplement the heat supplied by the collector.

Abstract: An oxidative evaporation process for treating waste water or other aqueous solutions containing organics or reduced forms of inorganics is described. The process relies upon excessive amounts of pressurized oxygen gas to both oxidize the solution and to increase the solution's evaporation rate. The oxidized liquid effluent from a reactor undergoes a series of flashing steps until a saturated solution is produced which readily crystallizes upon cooling.
