Title: Closure actuating device for railway hopper car doors - increases clearance between discharge opening of container and surface of discharge door
Inventor: FEARON JOSEPH G
IPC: B65D90/58
Filed: 1976-09-09
Abstract: The closure actuating device is for freeing rotation of discharge control doors for railway hopper cars of the type whre the door assembly is supported for rotation about a pivotal axis parallel to and beneath the discharge opening in the railway car. As a cam head (56) is rotated the distance between the pivot pin (60) and the support pin (62) increases, allowing the lower plate to drop. This is due to the eccentric slot (58), whose distance from the axis of pin (62) varies from one end of the slot to the other. This increases the clearance between the top surface of arcuate member (24) and the terminating edges of the discharge opening to allow normal rotation of the door to the open or closed positions, as may be desired.

Title: Pile fabric transfer printing - using short hot transfer stage followed by longer heating for penetration
Inventor: GLOVER RICHARD DONOVAN
IPC: D06P5/24
Filed: 1976-10-27
Abstract: Transfer printing of pile fabrics in two stages, comprises (1) applying the printed carrier to the pile and the sandwich heated under pressure, and (2) after removing the carrier, heating the fabric under conditions causing deeper penetration of the dye into the pile. Penetration is assisted by an air flow passing through the fabric, use of reduced pressure of application of an electrostatic field. Used for dyeing or printing of carpets, garments, etc. The brief heating during (1) prevents singeing of the carrier or pile. Increased amt. of dye can be applied to the carrier, without risk of sideways spread and blurring of the print during prolonged heating under pressure. The carrier can be re-used more often.

Title: Analysis method using solid electrolytes - with different electrolytes in tandem and unity ion transport number
Inventor: SUNDERMANN HEINZ DIPL PHYS DR
IPC: G01N27/417
Filed: 1976-11-06
Abstract: The determination of activity, concn. or partial pressure in solid, fluid or gaseous media by measurement of e.m.f. using solid electrolytes is based on temp. treatment and/or tandem connection of different electrolytes to bring the ion transport number of the electrolyte materials to 1 during the period of the measurement. With a zirconium dioxide electrolyte (4) in equilibrium under a low, reference pressure, hole conduction occurs. With a thorium oxide electrolyte (5) and high pressure equilibrium, excess-electron conduction can take place. If the electrolytes are placed in tandem and the ratio of the layer thicknesses (d1/do) is chosen so that the potential at the junction of the electrolytes is 1 no electron conduction can take place.

Title: Entirely optimised model delta wing - has pressure drag minimised at mach 2 and is defined by equations for neutral plane and thickness distribution
Inventor: NASTASE ADRIANA-MARIA PROF DR
IPC: B64C30/00
Filed: 1977-07-27
Abstract: The entirely optimised model data wing (1) is intended for a cruising speed of Mach 2. Both its plan form and its surface configuration have been chosen to minimise pressure drag at that speed. The shape of the delta wing is specified using an orthogonal system of coordinates with the origin at the nose or sharp tip of the wing. Using this system of coordinates, the equation defines the neutral plane Z(x1, x2) of the wing where x1 is the distance in the approach flow direction and (x2) is the distance along the span. For shockfree entry at cruising speed the centreline of the cross-sectional profiles is tangent to the axis x1. The equation for the thickness distribution about the neutral plane is given.
