Title: Procedure and device to construct electrical motor stators with more winding on a winding machine
IPC: H02N/
Filed: 1989-12-11
Granted: 1993-06-18
Abstract: This patent deals with the field of constructing small electrical motors and more specifically with constructing small stators for them. This consists of the fact that the invention planned to placed them on isolated heads where the thread is wound and where many terminal pockets are located, in a opportune position, along with the conductor derivations for which a place must be found, at the end of constructing the plugs to the various winders and applying the winding machine to the stator's plug means which, as related to the phase of introducing the winding tool (needle) in the stator, take the conductors in the winding phase, they carry them along with one of the terminal pockets planned for them, and they introduce them so as they can thus create an intermediary exit. The patent also provides for the possibility of not only carrying out the intermediary derivations by only one winder but also of being able to have completely separate winders with different purposes - from the winders themselves - for example different patterns for the change in speed or rather more exits from one derivation.

Title: Non-inflatable polyurethane tyre with internal buttressing webs
Inventor: GILMORE OSCAR P
IPC: B60C/
Filed: 1979-12-18
Granted: 1986-05-21
Abstract: Tyre is fitted on a wheel by means of two annular flanges spaced out axially. It has a circumferential wall of elastic material for running, a tread surface facing radially outwards and a pair of elastic side walls. These extend radially inwards from the tread wall to the assembly flanges and form a circumferential cavity. From the side walls, holding flanges extending radially inwards and join the axially inner faces of the assembly flanges. Webs able to yield under load extend across the cavity and are spaced uniformly around the circumference. The webs bind the side walls and are themselves an integral part of a circumferential support ring projecting radially inwards from the running wall. When load is applied to the rin as the tyre rolls, the webs pass one behind the other between the rim and the supporting surface working with the side walls to support and absorb the load. A non-inflatable tyre which can be assembled easily and correctly on a wheel rim, and which performs the functions of support and shock absorber is obtd. The tyre does not set up a stationary wave which resists rolling, in front of the zone of contact of the tread.

Inventor: SCHNEIDER RUDOLF
IPC: B23H7/10
Filed: 1981-03-23
Granted: 1986-10-22
Abstract: A method and apparatus for threading the electrode wire of a travelling wire EDM apparatus through an aperture in a workpiece. Prior to threading the wire through the aperture in the workpiece, the wire is continuously annealed and straightened and is passed through a nozzle to which fluid under pressure is supplied for forming a jet stream at the outlet of the nozzle. Prior to a threading or rethreading operation the wire, which is continuously fed by pulling by a wire conveyor mechanism, is cut off proximate to the outlet of the nozzle. The jet stream is aimed at the aperture in the workpiece and the end of the wire is fed through the aperture, while being maintained coaxially by the jet stream. The consecutive steps for feeding the end of the wire through the aperture in the workpiece are effected in sequence for first threading the wire through a pre-drilled starting hole in the workpiece or for rethreading the wire through a cut in the workpiece after accidental rupture of the wire during a cutting operation.

Granted: 1978-07-20
Abstract: A brake for the travelers of a twining ring or a spinning ring machine. Such machines have a series of rings each with an associated traveler and a common brake rod which can be operated to move braking units into the paths of the travelers. The braking units are made in ring form so that, when operated by the brake rod, they occupy substantially the whole of the paths of their associated traveler and can therefore engage the traveler and brake their motion wherever the traveler happen to be when the brake is applied.

Abstract: According to the invention, the regulator supplies excitation current both in addition and in subtraction, since the supplied current can vary not only in intensity, but also in direction, depending on the signal given by a control device, which is able to regulate the conduction of the regulator both as far as intensity and direction are concerned, according to the result obtained from the comparison between a reference voltage (124) and the voltage of the alternator itself, or, in any case, a part of it (123), said addition or subtraction been performed by electric or magnetic means. 
<??>According to a preferred form of execution, the electronic device having a two-directional conduction, which achieves these performances consists of a TRIAC (210) which feeds an auxiliary winding in one direction or the other; the TRIAC is piloted, in turn, by a control circuit (122) which sends out a triggering signal being in relation to the voltage of the alternator (123) and to a reference voltage (124). 
<??>In this form of construction the TRIAC can be replaced by two controlled diodes or by two transistors or similar means, being connected to each other in inverted parallel. 
<??>According to another form of execution, the circuit of the electronic regulator is made with two controlled diodes, transistors or similar means, which send current having the same direction to two separate windings being wound in opposite directions. 
<??>Yet another form of execution foresees the use of four controlled diodes, transistors or similar means which conduct in crossed pairs and feed a single auxiliary winding.

Abstract: In a process for growing enzyme crystals, small crystals are continuously removed from a crystallizer, dissolved and returned to the crystallizer to maintain a supersaturated state. The method permits the growing of large crystalline enzymes of uniform size of about 0.5 to 1 mm. Solid materials can be coated with crystalline enzymes by placing a solid material in the crystallizer such that crystals deposit on the solid material. The process is preferably used to produce crystalline glucose isomerase.
