Abstract: Case 3030 END RING ASSEMBLY FOR DYNAMOELECTRIC MACHINE               ABSTRACT OF THE DISCLOSURE           There is provided an end ring assembly for a squirrel cage rotor of an induction motor.  The assembly includes an end ring supporting structure for electrically interconnecting the ends of the rotor bars.  Instead of a steel retaining ring being used to minimize displacement of the rotor bars and end ring assembly relative to the rotor core structure, the present invention utilizes a glass resin banding wound about the rotor.  By using a glass banding reinforcement, the weight of the end ring support structure is reduced which increases the torsional resonant frequency of the end ring assembly.

Abstract: A method of quench-tempering a hot shaped glass sheet comprises supporting the sheet in a quenching station underneath a downwardly directed upper nozzle array and above an upwardly directed lower nozzle array by engagement of only a portion of the lower surface of the sheet. The portion engaged for support is interrupted by a generally uniformly distributed array of unsupported regions. An air stream is directed from the lower nozzle array up toward the lower surface of the glass sheet while an opposite air stream is directed down from the upper nozzle array toward the upper surface of the sheet. Generally all of the lower surface of the sheet is shielded except at the unsupported regions from the air stream of the lower nozzle array. A prestress field is thus formed in the sheet which corresponds to the distribution of the unsupported regions. The sheet is supported on and shielded by a plate having the same shape as the sheet but formed with holes at the unsupported regions. The sheet is transported into the station prior to quenching therein while supported on the plate and is transported out of the station after quenching therein while still supported on the plate.

Abstract: Symmetrical electrical snubber circuit for protecting at least two series-connected switch members (S1; S2) against excessive voltage and current increase during switching. The voltage increase over each of said switch members is limited by a series circuit of a capacitor and an element having diode action (D1, C1; D2, D2) connected in parallel with said switch members. The magnitude of the DC supply voltage is effectively limited by a further series circuit of a capactior and an element having diode action (D3, C3; D4, C4) connected with said switch members. A freewheeling diode (D5, D6) is connected in parallel with each of said switch members. By incorporating a coil (L1, L2) in the supply lines to the switch members, the current increase during switching-on of a switch member is limited. Like this, a symmetrical snubber circuit which is as low in stray inductance as possible is obtained. The energy stored in the coils (L1, L2) as well as the energy stored in the capacitors (C1; C2) being transferred to the further capacitors (C3; C4) due to resonant action. The energy in these further capacitors can then be discharged with the aid of energy transport means (ET). The snubber circuit according to the invention is in essence loss-free.

Abstract: The present invention concerns a heterogeneous catalyst particularly suited to the metathetic reactions of olefins in liquid or gas phase. Such a catalyst generally includes catalytically active species of tungsten on an inorganic support. The catalyst in accordance with the invention is prepared by vapourizing a precursor of tungsten, such as tungsten oxychloride or hexachloride and then routing the vapour of the tungsten-containing reagent into a reaction space where the vapour is brought to interaction with the support material at approx. 160 to 500  DEG C. The vapour pressure of the tungsten-containing reagent is kept sufficiently high and the duration of interaction with the support sufficiently long to keep the amount of the reagent at least equal to the number of available bonding sites of the support, whereby the bonding of the tungsten-containing reagent to the support surface is determined by the surface properties of the support. The catalyst can be posttreated after its preparation to modify its catalytic activity. The specific activity of the catalytic metal species of the catalyst according to the invention is high. <IMAGE>

Abstract: The invention concerns a press section in a paper machine, through which press section the paper web (W) has a closed and supported draw. The press section comprises at least two successive separate press nips (NP1,NP2,N3; NP3), dewatering of the paper web (W) being carried out at least in the first one of said press nips, preferably between two press fabrics (20,30) that receive water. The last press nip (N3;NP3) in the press section is an equalizing press nip (N3;NP3), which is separate from the preceding nip (NP2) and in which no substantial dewatering is performed. The paper web (W) is passed through the equalizing press nip (N3;NP3) from the preceding dewatering press nip (NP2) on a transfer belt (50) substantially not receiving water, on its substantially straight run. This run is continued after the equalizing nip (N3,NP3) as a run (50a) of substantially the same direction, on which run, by means of the difference in speed of the transfer belt (50), if necessary, some of the elongation of the paper web (W) in the machine direction is compensated for, which elongation takes place in the equalizing nip (N3,NP3). <IMAGE>

Abstract: 534,603. Impedance networks; transformers. STANDARD TELEPHONES & CABLES, Ltd. March 29, 1940, No. 5685. Convention date, June 2, 1939. [Class 40 (iii)] [Also in Group XXXV] In a filter of the balanced type comprising two or more sections 5, 6, Fig. 1, in tandem, the capacity unbalance is reduced by the connection of one or more condensers in series or diagonal between the input and output terminals. The stray capacities may be represented by a lattice network, Fig. 2, which may be so balanced that an E.M.F. applied across the input terminals will produce no output current if the product of the series capacities is made equal to the product of the diagonal capacities. This is done by the addition of a single condenser CA, CB or CC, Fig. 1, of suitable value. To balance for longitudinal currents, however, it is necessary either to make all the capacities of the lattice equal, in which case all three condensers CA, CB, CC are required, or to make the capacities such that the unbalanced voltage to ground at the input end is equal to but 180 degrees out of phase with that at the output end, which result may be obtained by the use of only two condensers CA, CB or CA, CC. In the two-section filter shown in Fig. 3, having a differential transformer T1, T2, at each end, the transmission through the piezoelectric crystals X1, X2 is balanced against that through the condensers C1, C2 for all frequencies outside the pass band, the balance being improved by the additional condensers CA, CB as in Fig. 1. The transformers T1, T2 allow the filter to be connected between unbalanced circuits, and they are tuned to the mid-band frequency by the provision of shunt capacities C3- C6. In order to correct for inductive unbalance, the couplings between the single winding W3 and the balanced windings W1, W2 are adjustable simultaneously in opposite senses, and preferably in addition the coupling between W3 and W1, W2 in series is adjustable. In the construction shown in Fig. 4, the winding W3 is carried by a tube 21 which is angularly adjustable in a circular slot 28 in a slide 22, and the latter is movable in longitudinal grooves within a tube 20 on which the balanced windings W1, W2 are wound.

Granted: 2001-06-05
Abstract: Disclosed is a laser pulse generator in which a single pulse is generated from a train of pulses. The amplitude of this single pulse is the addition of the amplitudes of the pulses of the train of pulses. This addition is done in a non-linear crystal inserted in an optical loop. The train of pulses takes the place of a pump wave applied to the non-linear crystal and the signal circulating in the optical loop takes the place of a signal wave. This signal wave therefore benefits from a transfer of energy coming from the pump wave because of the interaction in the non-linear crystal.

Granted: 1995-03-28
Abstract: Ambulatory ECG data monitoring and recording method and apparatus that selectively captures recorded data based upon the occurrence of a defibrillation pulse from an implantable cardio-verter/defibrillator monitor (ICDM) device is described.  The apparatus uses a single pair of skin electrodes to sample the ECG signal waveform and to monitor the voltage therebetween for the detection of a ICDM-produced pulse of characteristic amplitude and duration.  ECG data are continuously stored in a scrolling buffer of limited depth.  Detection of a defibrillation pulse is treated as a trigger event, prompting the continuation of ECG data storage only for a limited further period of time after which the present ECG data record is captured.  The buffered data are marked by the occurrence of the defibrillation pulse that prompted their capture, so that the information stored for subsequent playback indicates the timing relationship therebetween.  A new buffer is initialized and ECG data recording and defibrillation pulse detection continues.  Selectively capture-stored and marked ECG data can be played back to a remote site for diagnosis of a relatively long-term, ambulatory cardiac patient monitoring and recording session.          Optionally, the cardiac patient may manually trigger the capture-store of ECG data.
