Title: Method and apparatus for making stuffed casing products having one flat end
Inventor: STALL ALAN D
IPC: A22C11/02
Filed: 1991-01-14
Abstract: Abstract A method and apparatus for forming stuffed food products having one flat end by cutting a slit in a food casing forward of a stuffing horn and inserting an end flattening disc directly into the casing through the slit.  A fixture at the end of the stuffing horn holds the disc while the slit casing is drawn forward to clear the slit away from the disc.  The casing is then gathered and closed to capture the disc within the casing. On stuffing, the pressure of food product forces the disc to release from the fixture to form a flat leading end of the stuffed product.
Patent CA-2034376-A1 (CA)
Inventor: HOKANSON PAUL R
IPC: B60L50/12
Filed: 1991-01-17
Abstract: Method and apparatus for optimizing power delivered by a prime mover-driven electric power alternator to an adjustable speed electric traction motor during high speed operation. The alternator is suitably controlled to deliver constant power if its output voltage does not exceed a first predetermined magnitude corresponding to a "corner point" speed of the motor and to limit the voltage magnitude when motor speed exceeds this corner point, thereby preventing excitation current from exceeding the maximum continuous field current rating of the alternator. As motor speed increases above corner point speed, less power is delivered to the motor, but the power reduction is minimized by increasing the voltage limit above the first predetermined magnitude.      The amount of voltage limit increase, up to a predetermined maximum amount, is proportional to the amount load current in the motor decreases below its magnitude when motor speed equals corner point speed.      Concurrently with this voltage limit increase, the ratio of motor field current magnitude to load current is reduced, thereby weakening the motor field which enables the motor to run at its maximum allowable speed without exceeding the motor commutation limit whenever the predetermined maximum amount of voltage limit increase is obtained.

Abstract: The present invention relates to a device for determination of the topography of a surface by measuring its normal vector point by point, as well as devices for determination of the curvature of the surface in these points, and for determination of the orientation, position, shape and size of holes in the surface. The said devices are based on the use of opto-electronic sensors (1; 1-2) for measurement of the spatial position of active light sources.  The invention is furthermore based on an accessory tool (1; 4) consisting of a body (3a; 5), a minimum of two light sources (3a;  6-8) and three contact pins (3a; 10-12) or a plane contact surface. The contact pins or the contact surface positions the tool unambiguously onto a surface (1; 3). By knowledge of the positions of the light sources relative to the contact pins or contact surface of the tool, the orientation of this surface can be determined from the measured spatial coordinates of the light sources.
