Abstract: Case 781115 CONTROL SYSTEM FOR A MULTI-PHASE MOTOR Abstract of the Disclosure A motor control system for use in a high speed teleprinter or the like for controlling the rotational position and movement of a rotor, and apparatus driven by the rotor, by detecting back EMF induced into an unenergized field winding by rotational movement of the rotor. The out-put and input terminals of a first amplifier responsive to a first motor control signal, and a second amplifier responsive to a second motor control signal, are reactively coupled such that the amplifiers respond to either motor control signal to develop a signal simulating the signal into an unenergized winding of the motor due to mutual inductance with an energized winding. A differential voltage comparator provides a feed-back signal indicative of motor performance upon comparing the simulated signal with the signal actually induced. In the illustrated teleprinter application, the feedback signal is utilized to control energization of the carriage drive motor to assure accurate positioning of the teleprinter print head, and to provide an accurate indication of actual print head position to the signal processing circuitry of the teleprinter.

Abstract: ABSTRACT         A belt package for a surgical gown is disclosed in which a belt is fan-folded within a tubular belt support and one belt end is folded over and temporarily attached to the front of the belt support. The folded over belt end includes a line of weakness situated a short distance from the tip of the belt end to f from a detachable portion useful in insuring sterility.  The belt end is folded over by first folding the detachable portion against the rest of the belt end at a point on the belt near the weakened line but between the line and the point of exit of belt from the belt support.  The detachable portion is then folded against the belt support face by a fold in the belt near the point of exit from the belt support.  The end is temporarily attached to the belt support at point between the line of weakness and the first fold.

The tool includes a housing having an impeller section with an outlet adapted for connection to a vacuum-inducing source and an inlet through which ambient air enters the tool.  A rotatably mounted turbine-impeller is located within the impeller section of the housing and is adapted to rotate in response to the vacuum-induced fluid-flow.  In the preferred embodiment, a motion converting mechanism is connected between the turbine-impeller and a drive spindle equipped with a circular saw blade.  The motion converting mechanism converts the rotary output motion of the turbine-impeller to a rotary oscillating motion so that the saw blade is suited for use in cutting platter casts.  The air inlet of the housing is advantageously located in the cutting zone of the saw blade to entrain and remove debris generated during the cutting operation.

Abstract: Abstract of the Disclosure:           Composite metal tubing suitable for use as a high pressure fuel injection pipe for a diesel engine consists of a thick walled outer tubular member and an inner tubular member press-fitted in the bore of the outer tubular member.          The inner tubular member is made of stainless,chromium-molybdenum or manganese steel having a tensile strength at least equal to 48 Kg/mm2 and a wall thickness of 1.5 to 8.5% of the external diameter of the composite tubing.          The outer tubular member has a maximum external diameter of 30 mm. and is made of carbon steel.  The advantage is the avoidance of any need for complex treatment such as hardening of the surface of the bore.  There is also improvement in pressure resistance (or breaking strength) to internal flow pressure and a reduced tendency to cavitation in the bore as compared with conventional fuel injection pipes.

Abstract: 20.2200 ABSTRACT          The invention relates to a novel method and apparatus for the cyclical timing of the neutron bursts, spectral gates, tau determination gates, and background measurement periods in a capture spectroscopy measurement. Each measurement cycle period is divided in time into 62 tau units, where tau is the thermal decay time constant determined from the immediately preceding cycle period. The neutron accelerator bursts eight times, each burst lasting for one tau unit and beginning at 0, 6, 12, ....42 taus.  The capture spectral gates, two units long, follow each neutron burst after a one tau unit long delay.  Spectral background due to activation is measured in a long background window until tau equals 61, following a two tau delay from the eighth spectral gate and, properly normalized, is subtracted on a channel-by-channel basis from the spectrum accumulated from the capture spectral gates.  Tau determination gates I and II follow each neutron burst after a two tau delay.  Each gate I is one tau long; each gate II immediately follows gate I and is two tau long.  After the eighth gate II, a long gate III (49 tau to 61 tau) is provided for correcting-background counts in the tau determination gates I and II.

Abstract: ABSTRACT          A timed electric switch in a housing preferably for direct current loads such as for heating elements in vehicle windows, in which manually closable contacts supply current to the load and also to a timing circuit which may be digital, which completes a circuit through a holding solenoid for the contacts.  After a predetermined time or count has been achieved in the timing circuit, the current supply through the holding solenoid, is interrupted thereby releasing the con-tacts.  Provision is also made for allowing the second and subsequent timing periods to differ from the first timing period such as by independently supplying a potential to the timing circuit, such as through the vehicle ignition switch.          Reset of the timing circuit to produce the initial timing period once again is then effected by switch off and re-opera-tion of the ignition switch.  An illuminated indication is provided, preferably by a light emitting diode, which operates when the switch is operated.  Provision is made for altering the length of the second and subsequent time periods with respect to the initial timing period.

Abstract: SLIDE-BACK WAVEFORM ANALYZER                           Abstract An  apparatus  for  modifying  a  repetitive input signal  by  programmed variations  of offset  and gain such that the dynamic range of a waveform analyzer may be  fully  utilized  is  described.  Initial  offset and gain values are stored in a storage device. Then the input  signal  is  applied to a  summer  such that the signal plus the initial offset value is applied to a digitally-programmable  amplifier.  The  output  of the amplifier is then processed by a signal analyzer where a  list of offset and gain values needed to provide optimum resolution is calculated. The gain and offset data are stored in the storage device. Also calculated are the times at which offset and gain values should be applied to the input signal. The times are computed by counting clock pulses with reference to a pulse at the repetition rate of the input signal. These time data are sent to a controller which addresses the gain and offset  data  stored  in the  storage device.  The addressed  data  are  output  to  a  DAC to produce an offset signal and to the digitally-programmable ampli-fier to alter the gain thereof.
