Title: Linear asynchronous motor for traction or material transport - has edge effect fields for centering secondary part under primary windings
Inventor: POPOV A D
IPC: H02K41/025
Filed: 1980-04-21
Abstract: The linear motor includes a primary part which comprises two core components, each one laminated, running in mutually perpendicular directions. The cores (2) at right angles to the direction of motion (D) span the width of the secondary assembly (7,8) and have at least four slots. The cores (3) parallel to the direction of motion span the spaces between successive cores of the first type, and comprise one more section than the number of slots in the transverse cores (2). A concentrated multiphase winding (4,5) is arranged around the core teeth. The phase across the direction of motion follow the normal sequence to the centre of the core and then the reverse sequence to the opposite edge. In the direction of motion (D) all coils in any one line follow the normal phase sequence. The excitation provided by this coil and core arrangement gives the required linear motion, centering for the secondary part, and magnetic levitation.

Patent FR-2493305-A1 (FR)
IPC: C05C9/00
Filed: 1980-10-31
Abstract: A fertiliser composition which consists of a homogeneous mixture of urea on the one hand and of calcium carbonate on the other hand. The calcium carbonate can be in the form of lime from limestone, of dolomite, of seaweed or of chalk. The constituents are mixed in powder or granular form, it being possible for the particle sizes to range from fine dust to particle sizes such that in a screening test at least 97% of the constituents pass through the screen at a mesh size of 3 mm and at least 50% of the constituents pass through the screen at a mesh size of 1 mm. The ratio of the constituents in the mixture depends on the calcium and nitrogen requirements of the soil. The mixture in the form of a fine dust can be granulated to facilitate handling.

Title: Feeler probe with zero force contact for checking workpieces - contains galvanometer to indicate when gap between probe and workpiece is at threshold resistance value
Inventor: GALINOU RAYMOND
IPC: G01B3/00
Filed: 1980-12-01
Abstract: The probe (1) located in the chuck (2) of a machine tool has a body which contains a switch (8) for a current generator comprising a battery (7) and potentiometer (10). One terminal of this circuit is connected by a cable (15) to the piece part being measured. The other terminal is connected via a screened cable (19) within the shaft (20) of the probe body to terminate in a probe ball (17). A screw (21) permits correction for concentricity of the probe by modifying the shaft position w.r.t. the body. The potentiometer is adjusted to adjust the gap between the probe ball and piece part at which a galvanometer (9) in the current circuit indicates proximity of the piece part. A visible or audible indicator or alarm may be triggered when this distance is attained to avoid deformation of the piece part.

Title: Extra-corporeal blood circulation peristaltic pump - combines roller and low-vol. variable oscillatory helical pumps, with electric motor driven drum, in sequence
Inventor: GAY CHRISTIAN MARIE DENIS
IPC: A61M60/441
Filed: 1980-12-03
Abstract: A flexible conduit (1) of internal dia. about 10 mm is shaped into a semicircle (2) over a length where it is compressed periodically by rollers (3) revolving at the ends of arms (4), which extend radially from an axis (5) through the centre of the semicircle. The conduit continues into a spiral (7) wound at least once around a drum (6) which it enters and leaves axially. The frequency of oscillatory partial rotations of the drum gives rise to pulsatile flow in the conduit, and is determined by the speed of revolution of a crank (9) connected by a rod (8) to one end of the drum. The amplitude of oscillation may be varied by lengthening or shortening of the crank by an electrical screw jack (10). A flow rate corresp. to the diastolic pressure can be maintained with a non-return valve (11) in the conduit on the output side of the helical pump.

Title: Heat treatment of e.g. textile fabrics - by passing electrical current between contacts
Inventor: DOLEZAL MIROSLAV
IPC: D06B19/00
Filed: 1980-12-19
Abstract: Textile fabrics are heat-treated by passing an electric current using pairs of electrical contacts (1,2). According to the electrical resistance of the material (3) under treatment, modifications may be made in both the strength of the electric current and the distance between pairs of contacts. The use of electrical contacts, in the form of rollers, strips, ribs or plates, without need for further equipment, suppresses both thermal and electrical losses which have hitherto been a feature of this type of treatment.
