Abstract: A PROCESS FOR THE PRODUCTION OF DIISOCYANATES, SELECTED   DIISOCYANATES PRODUCED THEREBY AND THE PRODUCTION OF           POLYURETHANE PLASTICS THEREFROM               ABSTRACT OF THE DISCLOSURE          Diisocyanates corresponding to a specified formula are produced by reacting an alcohol corresponding to a specified formula with a nitrochloro-benzene in the presence of NaOH and/or KOH in powder form and a strongly polar, aprotic solvent to produce a dinitro compound corresponding to a specified formula.          This dinitro compound is hydrogenated to form the corresponding diamine which diamine is phosgenated to produce the corresponding diisocyanate.  The resultant diisocyanates may then be used as starting materials in polyisocyanate addition processes.

Abstract: CLOTHING HANGER                 ABSTRACT OF THE DISCLOSURE           A hanger is made with a molded plastic body and a metal hook.  The body has a vertical hole to receive the shank of the hook.  The lower end of the hole communicates with an opening or pocket in the hanger body.  The shank of the hook is provided with a diametrically enlarged head the end of which is tapered.  The cylindrical diameter of the shank is less than that of the hole and the diameter of the head is more than that of the hole.  The hook is assembled by forcing or plunging the head and shank through the hole until the head seats in the opening. The resilience of the plastic of the  hanger body restores the hole to its original diameter and  a substantially radial shoulder formed by the top of the head seats against the top of the opening about the end of the hole supporting the body on and for free rotation about the hook.  The substantially radial shoulder is canted at an oblique angle with respect to the radial direction and an annular area of reduced cross section is disposed between the shoulder and the cylindrical diameter of the shank.

Title: Phase shifter
Inventor: MEYER MAURICE A
IPC: H01P1/185
Filed: 1988-08-08
Granted: 1991-07-09
Abstract: ABSTRACT     The present invention relates to a reflection diode phase shifter that achieves amplitude equality between phase shifts of incident energy.  Amplitude equality is achieved by placing a resistor R to ground in parallel with the transmission lines connecting a four-port coupler to symmetric reflection terminators having an impedance that is varied by a diode.  The resistor is placed at a point on the transmission line having the lowest voltage when the greatest power loss is realized by the phase shifter.

Title: High resistance ground fault protection
Inventor: BERGMAN STEN
IPC: H02H1/00
Filed: 1988-09-15
Granted: 1992-12-01
Abstract: ABSTRACT            A protection device for high resistance ground faults in a power network according to the invention has a fault detection principle which is based on an indirect study of non-harmonic frequency components of the phase currents.  When such a fault has occurred, a considerable change of the energy contents of these frequencies arises.  This change can be detected by a device according to the invention.  If by comparison (4e) between digitized input signals (I') and a harmonic Fourier model (4d) of the same signals, i.e. generation of the residuals of the system, it is found that a difference exists, and if the corre-sponding loss function VN (4f) for a certain time exceeds a lower limit value - all on condition that a zero sequence current (Io) exists - then there is a high resistance ground fault on any of the phases of the network.

Abstract: ABSTRACT         A low speed decanting centrifuge for separating relatively large particulate material (e.g. yeast) from a feedstock is disclosed.  The centrifuge is clamped to a container and the centrifuge housing is pressurized to, in turn, pressurize the container and force feedstock upwardly into the lower bowl of the centrifuge.  A plurality of inverted frustoconical discs carry supernatant downwardly and inwardly for vertical transfer to a discharge chamber.          Particulate matter is centrifugally discharged continuously between engageable surfaces of the lower bowl member and the upper bowl member.  The invention provides for continuous recycle as the discharged particulate matter is returned under gravity to the container.  The centrifuge is reasonably inexpensive to produce from lightweight materials since it is not subjected to the high stresses of high speed centrifuges.          Also, by operating at low speeds, under 1000 r.p.m., there will be less cell compaction and damage to the particulate material than with high speed centrifuges.

Abstract: ABSTRACT OF THE DISCLOSURE         Fluid impermeable, protective clothing is usually impermeable in both directions, and thus sweat is unable to evaporate from the skin or from inner clothing.  A buildup of moisture is uncomfortable and, if prolonged, can cause pain and injury.  A simple solution to the problem is to insert a two-layer liner in the impermeable clothing which will absorb the sweat.  The liner includes an inner layer of vapour permeable, liquid impermeable material such as microporous Teflon (trademark) film, microporous polyurethane film or a hydrophilic polymer coating, and an outer layer of a material highly absorptive of both water vapour and liquid.

Abstract: Case 3029 A CYCLOCONVERTER DRIVE UTILIZING A DUAL              STATOR MOTOR                Abstract of the Disclosure A drive system which has a three phase synchronous motor for providing the driving power has a rotor with its rotor winding connected to a source of controlled current.  Each of the three phases in the stator winding has a first portion and a second portion.  The first portions of the three phase windings and the second portions of the three phase windings are arranged in parallel as separate three phase winding groups.  There is a controlled power source, such as a converter, for each winding portion with each power source being connected to a respective winding portion.  For the same output, the voltage at the motor terminals is less than for a motor with a standard three phase winding.  If there is a fault associated with a power source connected with a first winding portion, the motor may be run at reduced power using only the second winding portions and the power sources connected thereto.
