PURPOSE:To easily and accurately mold a looped belt of a required size, by burying a permanent magnet in a circular arc surface of a segment via a magnetic substance, and stretching between two adjacent segments a covering plate of non-magnetic material thereby to form a continuous cylindrical outer peripheral surface, and adhering each covering plate tightly to the circular arc surface of said ad...

PURPOSE:To perform tuning of control content or input information corresponding to fluctuation of a drive system by determining control information or correction value thereof stored in a control memory based on a tuning information. CONSTITUTION:When an optimal control information or correction value thereof is determined from a plurality of control information correcting values set in a control ...

A method of cutting a brittle workpiece comprises applying to the surface of the workpiece a pointed tool, applying high frequency vibrations in a longitudinal direction to the tool, and moving the tool along a line to be cut of the workpiece while applying substantially steady longitudinally directed pressure to the tool. Stress is thereby applied to the workpiece as a combination of short impuls...

A C.T.C. machine for processing of tea leaves and having a meshing pair of serrated rollers 20, 30, caused to be rotated in opposite direction to each other is characterised in that one of the said rollers (30, Fig. 2) is journalled at its both ends in a pair of bearing assemblies, which are slidable in relation to the machine frame in the radial direction of the rollers, and one of the said beari...

Yarn 10 is fed from a package 11 to a point of knitting 12 on a knitting machine or other processing station along a substantially closed path defined by tubing 13. Adjacent to a positive feeding device 14, the tubing 13 includes a section 15 which can be closed for initial blowing of the yarn through the tube, and opened to allow threading of the yarn 10 around the feeding device 14. This facilit...

A yarn stripper device (10) comprises a housing (11), a power driven rotary saw (12), a slide (13) adapted to carry a yarn holder (14) bearing unused yarn (15) and movable to and fro with respect to the housing (11) in order to advance the yarn holder (14) to the saw (12) so that yarn stripping can take place and then to retract the stripped yarn holder, drive means (16) coupled with the slide (13...

A transfer device for a four-wheel drive vehicle has a transfer shaft (5) rotatably mounted by first (11) and second bearings (8), and a transfer gear (6) rotatably mounted on the transfer shaft (5) between the bearings. A coupling device (17) is provided outside the first bearing (11) for engaging the transfer gear with the transfer shaft, and a bevel gear (7) is secured to the transfer shaft at ...

Polyisocyanurate foams are prepared by reacting together an organic polyisocyanate, a blowing agent, a trimerization catalyst, and a minor amount of a polyol mixture prepared by digesting polyalkylene terephthalate, particularly polyethylene terephthalate, with a polyol, especially a glycol. Laminates of such foams exhibit a high degree of fire resistance, low smoke evolution on combustion, low fo...

A ski attachment device having a safty feature that allows disengagement of the boot from the ski in the case of lateral or front falls of the skier. The device comprises a rear unit adapted to be attached to the ski and including a spring for applying a longitudinal forward thrust to the rear of the boot. A front unit includes a plate having a "V" shaped seat to be engaged by a grooved rotatable ...

A drilling tool which has at least one helical fluid flow channel at its interior, is composed of a hard metal core having an exterior surface and a hard metal tubular casing having an interior surface. The casing encloses the core with their surfaces in firm contact so that the core and casing form a composite body. Each channel is formed as a groove in the surface of the core or casing.

A smooth surface e.g. a motor body panel (12) is inspected for surface contour imperfections by traversing an illuminating beam (15) directed at an angle to the perpendicular to the surface and sensing light from the illuminated surface part along an optical path inclined oppositely to the beam and noting changes in the sensed light, during the traversing, due to changing contours of an imperfecti...

A programmable device for signal processing applications in which short loops of digital data are processed repetitively and in parallel. The device consist of five independently programmable subsystems whose functions are able to operate simultaneously. The apparatus is intended for use in a connection with a digital multiplier device and a digital memory device for such signal processing applica...

The substrate of conventional reagent test devices is replaced by polyester screen material having a nominal filter rating of from about 80 to about 130 microns such that liquid present in the reagent matrix material of the test device is retained therein and prevented from running over onto other reagent matrix areas present on the same reagent test device.

A water bag (10) of plastic sheet material for irrigating the large intestine in colostomy patients is provided on the outside with a thin thermometer (32) of the kind comprising encapsulated liquid crystals for registering the temperature of the water in the bag (10) within the range of 37 DEG C +/- 5 to l0 DEG C. Preferably the thermometer (32) is adapted to show the temperature by a colour reac...

In einer Anlage zur Führung von Flurförderzeugen mit wenigstens einem lenkbaren Rad und einer richtungsbestimmenden Signalübertragung auf das Flurförderzeug mit einem Sensor, welcher mit einer Signalführung (4, 15, 16), insbesondere Führungsdrahtanordnung im Fahrboden der Anlage zusammenarbeitet, ist der Sensor zur mittigen Abtastung der von einem Leitelement gebildeten Signalführung vorgesehen un...

Ein Vorderbacken einer Sicherheitsskibindung weist ein skifestes Gehäuse (15), eine Auslösefeder (14) und relativ zum Gehäuse (15) seitlich ausschwenkbare Sohlenhalterarme (18) auf, welche die Spitze des Skistiefels in seitlicher Richtung am Ski (40) festlegen, jedoch bei oberhalb eines vorbestimmten Auslösewertes liegenden seitlichen Kräften an der Spitze des Skistiefels gegen die Federkraft seit...
