Patent number: 4915018Abstract: A diaphragm piston assembly in which an annular ring member is provided, preferably at the outer clamping periphery of the diaphragm between the underside of the diaphragm and body, to exert a force on the diaphragm in the direction of the cover that clamps the diaphragm to the body, thereby encouraging the diaphragm convolution to assume a disposition in a preferred direction corresponding to the direction in which the convolution is predisposed by the inherent "spring effect" of the diaphragm.Type: GrantFiled: September 13, 1988Date of Patent: April 10, 1990Assignee: American Standard Inc.Inventors: Daniel G.

Patent number: 4914138Abstract: A polymer blend comprises a high nitrile polymer and a compatible polyolefin functionalized with an unsaturated compound selected from the group consisting of unsaturated carboxylic acids, esters, anhydrides and imides. Such blends can be used to form films and membranes having improved thermal, mechanical and optical properties. The blend combines the low oxygen permeability of high nitrile polymers with the low water vapor permeability of the polyolefins and are, therefore, useful in the packaging industry. A method for forming blends of high nitrile polymers with polyolefins includes the step of functinalizing a polyolefin prepared from a monoolefin having from 2 to about 6 carbon atoms with an unsaturated compound selected from the group consisting of unsaturated carboxylic acids, esters, anhydrides and imides and blending from about 99 to 1 parts by weight of the functionalized polyolefin with from about 1 to 99 parts by weight of the high nitrile polymer.Type: GrantFiled: August 22, 1988Date of Patent: April 3, 1990Assignee: The Standard Oil CompanyInventors: Elena S. Percec, Lucy Melamud, Gerald P. Coffey

Patent number: 4914410Abstract: With a very small hinged armature relay of the printed circuit board type with dual-in-line terminal configuration intended for a very high number of actuations there exists the problem to design the armature resetting spring in such a manner that it withstands said high number of actuations without any risk of failure. For the present relay this problem has been solved by providing a leaf spring as the armature resetting spring being connected in a form-locking manner to the legs of a U-shaped armature (13) extending substantially in parallel to said legs and being connected in a force-locking manner to the coil former (10) constituting the relay structure, this in contrary to the usual way wherein said flat spring would be connected to the legs of the E-shaped magnet yoke (12). By this means it is possible to provide the leaf spring with a length at least equal to the length of the legs of the armature.Type: GrantFiled: November 29, 1988Date of Patent: April 3, 1990Assignee: Standard Telephon und Radio AGInventors: Hans A.

Patent number: 4911226Abstract: Strip steel is continuously cast by immersing a mold into a melt of liquid steel, solidifying liquid steel on a starter bar disposed within the mold, and oscillating the mold as the starter bar is withdrawn upwardly from the mold. The mold includes, at its lower end, an insulating ceramic entry die. The remainder of the interior surface of the mold is defined by a water cooled copper or copper alloy liner. The mold can be vertical or it can be inclined at an angle to the horizontal in order to facilitate feeding strip steel directly into a rolling mill or hot coiler. Alternatively, the interior of the mold can be curved so that strip steel issuing from the mold is directed horizontally into the rolling mill or hot coiler.Type: GrantFiled: August 12, 1988Date of Patent: March 27, 1990Assignee: The Standard Oil CompanyInventors: John E.

Patent number: 4912643Abstract: A position sensing apparatus 1 having two base stations spaced-apart a known distance on a datum line L. The base stations each comprise generators 2(a) and 2(b) which emit a rotating laser beam. The rotating laser beams are detected by a movable sensor 6 and datum sensors 7(a), 7(b) which are associated with the generators 2(a), 2(b) and are located on the datum line L. The time difference between detection of each laser beam by the movable and datum sensors 7(a), 7(b) is determined and is used to calculate positional angles .alpha. and .beta. between position lines between the movable sensor and each base station and the datum line L. As there are only two laser beams, they are differentiated by contra-rotation in the same horizontal plane. Vertical position is determined according to the vertical position on the movable sensor 6 at which the beams are detected.Type: GrantFiled: October 30, 1987Date of Patent: March 27, 1990Assignee: Institute for Industrial Research and StandardsInventor: Terence P.

Patent number: 4904027Abstract: A pneumatic pressure control arrangement for controlling the brakes of railway vehicles. A manual brake command controller converts a selected brake position into a corresponding electrical signal. An application magnet valve is connectable to a source of air pressure and to a storage device. A release magnet valve is connectable to atmosphere and to the storage device. An electropneumatic transducer senses the pressure in the storage device and provides a feedback signal. A microprocessor receives and compares the electrical signal with the feedback signal to develop an error signal which initially energizes the application magnet valve and the release magnet valve upon request of braking effort, and which subsequently pulses the application magnet valve when the pressure in the storage device is within a preselected control range, and which finally deenergizes the application magnet valve when the pressure in the storage device is within a preselected deadband range to cause a lap condition.Type: GrantFiled: October 3, 1988Date of Patent: February 27, 1990Assignee: American Standard Inc.Inventors: Elmer T. Skantar, Walter J. Sanders
