Title: Reversible brushless DC motor - has permanent magnet armature, is variable in speed and may be produced in linear or rotating versions
IPC: H02K33/12
Filed: 1975-09-16
Abstract: A linear or rotating motor has stator windings fed with DC. It has a rotor made up of permanent magnets. The rotating motor is reversible, brushless and variable in speed. The supply to the windings is in the form of phase displaced interrupted DC, speed being dependent on the phase relationship of the DC pulses.

The rotating motor has four windings placed symmetrically on either side of a rotor carrying four rectangular permanent magnets on the same radius as the coil pattern. The phase displaced DC pulses are generated electronically (17), the strength of the permanent magnets remains constant due to the maintainance of the field direction.

Patent FR-2324424-A1 (FR)
IPC: B26F1/00
Filed: 1976-09-16
Abstract: A method of punching a small hole in a precision mechanics workpiece, in that the thickness of the workpiece is reduced by the application of pressure in the region where the small hole is to be punched and the material is thereby strengthened, steps being taken to cause the material subjected to pressure to be displaced in the direction of pressure and to yield at right angles hereto. The small hole is punched in the region subjected to pressure at a distance from the edge of that region corresponding at least to the diameter of the small hole, so that the small hole is certain to be punched at a location in that region where the material is strengthened and sound.

Title: Traditional rice cakes mfr. - by extrusion of mixt. of rice and water, rolling into sheets, cutting and drying
IPC: A23L7/10
Filed: 1976-09-30
Abstract: Flat round rice cakes, (Banh-Trang), are mfd. in a machine in which a mixt. of rice flour and water is heated; the paste obtd. is passed between rollers and the sheet is cut to the desired dimensions and dried. Mixing is effected in tank with its stirrer and heating means. When the mixt. has attained satisfactory properties, it is taken by the dosing pump via pipe to the cooking and mixing extruder. The temp. is brought up to 99 degrees C by heaters arranged around the cylinder. The latter has a compression chamber at one end with a slit through which the paste is extruded. The extruded strip then passes between the rollers of a double two-high rolling mill where it is rolled into a sheet. A rotating cutter divides the sheet into the desired shapes and the cakes fall onto the conveyor belt to be carried through the insulated drying tunnel. This is heated by infra-red heating lamps which maintain the temp. between 40 and 70 degrees C. The prod. has exactly the same properties and the same appearance as those made by hand but they have a regular thickness and the rate of prodn. is greatly enhanced.

Title: Measurement of linear acceleration for inertial navigation - uses polarisation interferometer with ultra-sensitive ellipsometer to determine direction and magnitude of acceleration
Inventor: ORSZAG ALAIN
IPC: G01P15/093
Filed: 1976-11-04
Abstract: Precise measurement of linear acceleration is required for inertial navigation. These measurements are obtained by combining a polarisation interferometer with an ultra sensitive ellipsometer. Variations of ellipticity are translated into movement of a mirror and then into acceleration. A separating cube (2) and two mirrors (3, 4) comprise an interferometer. The cube and one mirror (3) are attached to the housing (5) in turn attached to the housing (5) inturn attached to the accelerating mass (c). A test mass (6) is attached to the housing by a thin thread (7). A laser source (1) provides light for the interferometer whose output is directed to the ellipsometer (17). This laser source is common to three accelerometers to give direction of acceleration.

Title: Painted surface colour modification method - by applying paper to painted surface of tinted glass which is mounted with support in stainless steel frame
IPC: B44D2/00
Filed: 1977-02-21
Abstract: The colouring of a painted surface can be modified and its brilliance increased by painting on a sheet of tinted glass.

Title: Preserving foods and biological products in a vacuum - involves slowly passing in moist air to increase pressure, re-evacuating and repeating cycle
IPC: A23B7/148
Filed: 1977-03-11
Abstract: A process for preserving food products, perishable foods and all products of biological origin comprises keeping the products in a hemetically sealed enclosure, forming a vacuum corresp. to x millibams pressure, then progressively replacing a fraction of the volume evacuated to reduce the vacuum to y millibams, by passing in purified moist air. The vacuum is then restored to x millibams, then moist air is slowly admittedly until the vacuum is y. The operation cycle is repeated during the preservation period at a temp of -5 degrees C to +16 degrees C. The process is carried out in an appts. with moist air inlet and evacuating outlet and means for automatically opening and closing the inlet and outlet openings according to the pressure. Examples of applications are to fruit, vegetables, dried flours and human blood, and organs which may be preserved for months. The process inhibits growth of aerobic and anaerobic microoganious. Also in the case of fruit and flowers, ethylene formed is removed which, if left, enhances ripening and deterioration.

Title: Underground irrigation system for football pitch - has water level sensors and ohmmeter to monitor nutrient requirements with perforated drain pipes housed in covered gravel-filled trenches
Inventor: VILBERT LEONCE
IPC: A01G25/00
Filed: 1977-04-22
Abstract: An enclosure, such as a football pitch, has an impermeable liner (12). A series of trenches (9) are filled with gravel and have perforated drain tubes (8). A filter covers each trench, and a pair of tubes (8) in adjacent trenches and joined and connected by pipe (16) to an overflow chamber for drainage via pipe (19). A perforated tube (22) is fed with water and, if necessary, nutrients from a control station. Sensors detect variation of the water level (21) to cause water to be supplied through tubes (22) when the level is low. Ohmmeters buried in the ground measure conductivity so that the need for liquid nutrient can be gauged and the grass can be fed in via tubes (22).

Title: Animal fur processing - by making cuts parallel to centre line in specified widths, lengths and sewing pattern (NL 8.7.77)
IPC: C14B15/10
Filed: 1977-07-06
Abstract: Dressed animal furs are processed by cutting on both sides of the back at a distance from the centre line two strips of equal width, amounting to half the width of the dorsal strip. Their length is chosen in such a way that the air structure remains uniform after the pairs of strips have been sewn together along the edges facing each other. Method reduces labour needed for conventional herringbone type of cutting and re-sewing. The material, wasted for the many sewn seams is also saved. The latter can in the case of mink amount to a saving of four pelts per fur coat. In the case of mink, the fur is cut into five strips (2-6). The strips (3-6) are of equal width but only half the width of the dorsal strip (2). The strip (2) extends from the tail end (9) to the cut (7) near the front legs, the strips (3,4) run from the tail end (9) further forward to the cut (10), and the strips (5,6) extend from the tail end (9) to the cut (11) near the head. The outer strips (15,16) are sewn to each other along the facing edges by a straight seam, followed by drawing a sinusoidal line. After wetting this line is stretched into the position where the straight seam was and the fur is fixed in this position and allowed to dry. Two strips of 4 mm width are cut at a distance of 2mm from the centre line of the dorsal strip (2). These are used at the junctions between strips (3,4) and (5,6).
