Title: Multiaxis redundant fly-by-wire primary flight control system
Inventor: BUUS HENNING
IPC: G05D1/00
Filed: 1993-05-05
Abstract: A redundant, multi-channel fly-by-wire control system for use in an aircraft is disclosed. The system includes a left flight control channel (60), a center flight control channel (80) and a right flight control channel (90). Each control channel is capable of flying the aircraft in the event the other two channels fail.  Included within each control channel is an actuator controller electronics unit (ACE (62, 82, 92)), which transmits a series of pilot control transducer signals to a set of primary flight computers (64, 84, and 94). The primary flight computers combine the pilot control transducer signals with data obtained from an air data and inertial reference unit (145) to generate a set of flight surface commands. Each ACE selects a set of flight surface commands to control the movement of a set of flight control surfaces on the aircraft.

Title: Method and apparatus for applying resilient athletic surfaces
Inventor: DALUISE DANIEL A
IPC: B05D1/02
Filed: 1993-06-02
Abstract: ABSTRACT A method and apparatus for continuously coating particulate such as rubber with liquid binder and applying the same to a substrate to form resilient athletic surfaces. Total encapsulation of the particulate with the liquid binder is accomplished prior to applying the mix to the substrate. In addition, the method of delivery of the particulate and binder maintains the ratios thereof uniform.     In its method aspects, the instant invention involves separately introducing a stream of particulate and a stream of binder into a spray nozzle, where they are combined and delivered to the substrate. The apparatus includes a nozzle assembly having a central lumen and an elongated tip, the lumen being formed so as to force the particulate introduced therein to follow a circuitous or indirect path therethrough and thereby decrease its velocity prior to being ejected from the nozzle.

Title: A process for producing a butter-like food fat
Inventor: BERNTSEN STEN
IPC: A23D7/02
Filed: 1992-05-08
Abstract: A butter-like food fat being directly spreadable at refrigeration temperature, i.e. 4 to 5 °C, and preferably containing 80 to 83 % fat is produced by addition of vegetable oil, water, and salt. Initially conventional butter is produced, which preferably con-tains 80 to 83 % fat and which is made exclusively from milk. Subsequently, the conventional butter is passed continuously through a tight, closed plant, whereby the butter initially passes through a kneading station followed by addition of half the total amount of added vegetable oil. Then the butter mixture passes through a mixer, whereafter the remaining portion of the amount of added vegetable oil and water and salt are added. In this manner buttermilk results exclusively as a by-product from the pro-duction of the conventional butter and contains thererefore nothing but pure milk fat. Accordingly, the buttermilk can be used ~ market milk and sold at the highest possible market price. In addition, a particularly high production flexibility is obtained dur-ing the production of butter.
