Patent DE-3063578-D1 (DE)
Title: Manufacture of blasting explosive compositions
Inventor: SUNDARAM BALAKRISHNAN GANAPATH
IPC: C06B47/14
Filed: 1980-03-28
Granted: 1983-07-07
Abstract: Blasting explosive compositions, generally in the form of slurry explosive compositions, which contain ammonium nitrate as the sole or principal inorganic oxidising salt and a methylamine nitrate mixture as the sole or principal sensitizer, are prepared by reacting in the liquid phase ammonium nitrate and formaldehyde to form an oxidizer/sensitizer blend which can then be mixed with other appropriate constituents to form the required blasting explosive composition, the reaction of the ammonium nitrate and formaldehyde being carried out in the presence of urea in order to reduce the amount of free formic acid which is unexpectedly produced in the reaction, since the presence of formic acid in the reaction mixture is undesirable in that it affects the production of a stable gel therefrom and if converted into a formate reduces the strength of the explosive composition.

Title: Method and apparatus for cutting one layer of fabric and stacking the cut pieces
Inventor: ETCHEPARRE JEAN
IPC: A41H43/02
Filed: 1982-05-19
Granted: 1985-03-21
Abstract: The present invention relates to a method and apparatus for cutting pieces of fabrics of uniform thickness and for stacking these pieces. The method generally includes arranging and maintaining a length of unrolled fabric on a cutting table which comprises a revolving cylinder which rotates so that the length of fabric is positioned to face a cutting instrument. The fabric is cut out according to one or more predetermined patterns when the cylinder stops rotating. Displacement of the cutting instrument over the circumference of a cylinder follows the generators of the cylinder during its motion. After the fabric is cut, the cylinder rotates to deposit the cutout pieces onto a fixed or mobile receiving/stacking table which is positioned under the cylinder. During such deposition, a new length of fabric is simultaneously arranged on the cylinder preparatory to being cut. Alternately, a conveyor belt can be used in lieu of the cylinder.

Title: Angular rotary position encoder
Inventor: WIBLIN WAYNE
IPC: G01D5/249
Filed: 1984-04-30
Granted: 1989-09-28
Abstract: Information related to the rotary angular position of a steerable wheel portion of an electric vehicle is required for proper control of the vehicle and especially for differential control of the driven wheels of the vehicle. Available rotary position encoders are expensive, prone to damage in an industrial environment, and sensitive to misalignment between the encoder components. The instant apparatus provides a simple and durable rotary position encoder having a plurality of sensors positioned on a first mounting member and a plurality of sensible members positioned on a second mounting member. The apparatus is digital in design and the particular location and arrangement of the sensors and sensible members advantageously compensates for overtravel and misalignment of the encoder components.
