Title: Concrete forming system for curved walls
Inventor: LEHMANN LARRY W
IPC: E04G11/06
Filed: 1988-03-15
Granted: 1992-04-07
Abstract: ABSTRACT OF THE INVENTION A curved concrete forming structure to provide a 1000 psf system for forming curved walls having a radius in excess of 5'. The structure includes a series of arcuately curved metallic panels secured in stacked side-by-side assembly. The improvement particularly concerns a panel which is comprised of a flexible metallic skin plate. Spaced vertically extending ribs are positioned along the length of the panel on one side thereof. The ribs and the skin plate have essentially the same vertical dimensions. A pair of vertically spaced arcuately curved angles are provided which angles have identical diameters that correspond to the diameter of the concrete wall to be poured using the concrete forming structure. The curved angles are substantially stiffer and inflexible compared to the flexible skin plate. Means or fasteners secure the curved angles in abutment with opposite ends of the ribs, and with the flexible skin plate being moved from a flat form and secured by the means in a curved form corresponding in diameter to the arcuately curved angles to form said arcuately curved panel, the curved panels being assembled in stacked assembly providing a smooth continuous radius free of chords or flat spots.

Granted: 1992-08-04
Abstract: RETRACTABLE EYESHEILD        Abstract A retractable, partial eyeshield assembly is attached to a single eye sighting device attached to, for example, a video camera. The partial eyeshield assembly is constructed so that it covers a portion of the medial field of view of the user's nonsighting eye. The obstructed portion of the nonsighting eye's medial field ofview corresponds to that portion of the sighting eye's that contains only the image transmitted through the single eye sighting device's sighting aperture. By obstructing the portion of the nonsighting eye's medial field of view, the corresponding field of view in the sighting eye dominates. The obstruction of the portion of the nonsighting eye's field of view is achieved without obstructing asubstantial portion of the nonsighting eye's peripheral and medial fields of view.

Abstract: The present invention provides novel silyl 2-amidoacetates and silyl 3-amidopropionates which are the reaction products of azlactone and silanol reactants.  The novel products result from nucleophilic addition of a soluble or insoluble, low or high molecular weight reactant containing one or more silanol groups and a soluble or insoluble, low or high molecular weight reactant containing one or more azlactone groups.  The reaction products provide for high adhesion between the siliceous and azlactone reactants, as would be useful as protective coatings particularly on silicon-containing materials.  It has been recognized in the present invention that silyl 2-amidoacetates and silyl 3-amidopropionates are useful linkages between silanol and azlactone derived materials.

Abstract: MASS-VOLUME FLOWMETER          Abstract of the Disclosure A flowmeter measuring mass flow rate or volume flow rate or mass and volume flow rates of fluid comprises a pair of flow passages (3 and 4) and a pair of flow sensors (7 and 8) respectively measuring flow rates through the two flow passages (3and 4). A flow obstructing member (12) at least partially obstructs at least one of the two flow passages (3 and 4), wherein a bias force acting on the flow obstruct-ing member (12) tends to increase the degree of obstruction of the fluid flow through said at least one of the two flow passages, while the fluid dynamic force exerted on the flow obstructing member (12) by the fluid moving through the flowmeter tends to decrease the degree of obstruction of the fluid flow through said at least one of the two flow passages. The mass flow rate of the fluid moving through the flowmeter is determined as a function of the signals provided by the pair of flow sensors (7 and 8), and the volume flow rate of the fluid moving through the flowmeter is determined as another function of the signals provided by the pair of flow sensors (7 and 8). The density of the fluid is determined as a ratio of the mass flow rate to the volume flow rate.

An insulating and sealing device of insulation material, such as fiberglass or foamed material partially enclosed in an open-topped envelope of plastic or foil material is circumferentially located in the space between the first wall and outer wall at a preselected location within the space.  The insulating and sealing device which is of a radial thickness greater than the radial width of the space is radially compressed between the first wall surface and second wall surface.  An expanded foam thermal insulation material fills the space to one side of the insulating and sealing device.  A method of making the appliance having two spaced apart walls includes the steps of positioning an insulating and sealing device of resilient, flexible insulation material on and in contact with one of the walls, the insulating and sealing device having a radial thickness greater than the radial width of the space, and positioning the two walls into transverse spaced apart relationship radially compressing the collar between the two walls.  In another embodiment, the method of making the appliance includes the steps of positioning the two walls in transverse spaced apart relationship, and positioning an insulating and sealing device of resilient, flexible insulation material within the space in contact with the facing surfaces of the two walls, the insulating and sealing device having a radial thickness greater than the width of the space.

Abstract: A front wheel side luggage carrier (1) for bicycles comprises a strut arrangement (4) having two struts (7, 8), which when in the position of use extend substantially vertically and approximately parallel to a plane that intersects the front axle of the bicycle at right angles, and having an upper and a lower attachment arrangement (5, 6). Via these arrangements, the side luggage carrier (1) is secured to adjacent legs of the front wheel fork (2) at two points, one of which is located near the front axle and the other is spaced apart therefrom. In order to provide a simple structure, which even under adverse conditions will not tend to vibrate during the ride and which will be largely independent of the shape of the front wheel fork (2), the two vertical struts (7, 8) are joined integrally together at their lower end by means of a connecting cross portion (11), which bears the lower attachment arrangement (6). At their upper ends, the two vertical struts (7, 8) are bent toward one another, forming two transverse bent-over portions (23, 24) in alignment with one another, which in turn are bent at their free ends, forming two support struts (27, 28), towards the lower attachment arrangement (6) on which the support struts (27, 28) are anchored. The upper attachment arrangement (5) is provided on the support struts (27, 28).

Abstract: A method and a device for correcting the cuff pressure in the indirect, non-invasive and continuous measurement of the blood pressure in a part of the body by using a plethysmograph in a fluid-filled pressure cuff, an electronic control circuit, and an electric pressure valve. The cuff pressure is controlled by the plethysmographic signal in closed-loop operation with the aid of a servo-reference level obtained via a memory circuit. The servo-reference level, in operation of the device, is adjusted by opening the closed loop of the control circuit for a short interval, after which, in open-loop operation the cuff pressure is adjusted at an intermediate pressure derived from the pressure last measured and the servo-reference level is adjusted via the memory circuit.
