Abstract: LINEAR ENERGY CONSERVATIVE CURRENT  SOURCE                 ABSTRACT OF THE DISCLOSURE A regulated energy-conserving   current source in-cluding a large inductance provides substantially all of the desired current to a deflection yoke or other load by modu-lation of an electronic switch which is turned on in response to the current drawn by an amplifier being above an upper threshold and is turned off in response to the amplifier current being below a lower threshold.  Feedback of the load current controls the amplifier to make up the difference between the desired current and that supplied by the large inductance.  Embodiments include a trigger, a differential amplifier with positive feedback, and windings coupled to the large inductance.  As an energy saving adjunct in a magnetic deflection system for a CRT, bipolar embodiments, employing a single large inductance with duplicate other apparatus, provide regulated current of either polarity or zero magnitude.  External feedback and local feedback embodiments are disclosed.

Abstract: ABSTRACT           It is known to hydrolyze, using protective groups, under strictly controlled reaction conditions the acylamino groups of -6 or -7 substituted penicillins or cephalosporins, respectively.  However due to the reactive nature of these substances, generally the yields are low. Further more the protective groups are costly.  Thus this the known reactions are unsuitable for industrial processes.  The present invention over comes this problem by provid-ing a novel process for the hydrolysis of -6 or -7 substituted penicillins, cephalosporins and -3 substituted cephalosporins where in the protective group is an oxalyl halide, which substances are commercially available at a low price and not dangerous to handle.

Abstract: FORMATION OF SEGMENTS FOR  CONTAINERS AND THE LIKE        Abstract of the Disclosure A flat metal plate is first formed into a suitable segment of a large generally spherical body.  It is then properly positioned on a horizontal cradle and its edges cut vertically as if from infinity, i.e. so that they are all parallel.  A cutter then traverses the pre-cut edge to form the proper contour for welding.  The pre-cut edge itself forms an accurate fixed reference and cooperates with guides on the face of the curved plate to keep the axis of the milling cutter tool substantially perpendicular to the surface of the plate at the point of milling contact.  When all segments are so made and then joined, the resultant generally spherical body will be within substan-tially closer tolerances.

Abstract: ABSTRACT         A circuit arrangement for the frequency division of high fre-quency pulses, comprising a first pair of transistors which are alter-nately driven into conduction by the pulses, whose output currents are each passed through a group of at least two transistors, whilst the bases of the transistors of the groups are each time connected in a cyclically shifted sequence to tappings on resistors which connect the collectors of each time two different transistors from different groups.  In inte-grated circuit technology these tapped resistors are constituted by the parasitic resistance of a semiconductor layer which serves as a common collector for the transistors of said groups.  The base zones of these transisitors are arranged in the collector semiconductor layer in a geo-metrical sequence corresponding to said cyclic sequence.

Abstract: ANALOG-TO-DIGITAL CONVERTER                     ABSTRACT OF THE DISCLOSURE     An analog to digital converter wherein an incremental pulse width modulator controls first and second modes of operation of a bridge network of switches such that the bridge network of switches passes a precision current from a current source into a summing input of an integrator during the first mode of operation and away from the summing point of the integrator during the second mode of operation.          The bipolar precision current from the bridge network of switches is summed with an analog current at the summing input of the integrator to cause the integrator to develop a voltage signal proportional to the integral of the sum of these currents.  In response to the voltage signal and to clock pulses, the incremental pulse width modulator precisely controls the first and second modes of operation of the bridge network of switches and enables an output circuit to generate a digital representation of the amplitude of the analog current.

Title: Method and apparatus for forming thermally responsive  snap-acting bimetallic actuators

Abstract: Abstract of the disclosure A method of forming a snap-acting thermally responsive bimetallic actuator comprising (1), forming from sheet bimetal, a member having an aperture with an arcuate outer perimeter and an inner perimeter defining a tongue free at one end, said free end being close to the outer perimeter, the outer and inner perimeters smoothly merging at rounded ends of the aperture adjacent the tongue root, and the radial width of the member at the tongue root being substantially greater than the width opposite the free end of the tongue and (2) pressing said member overall between a die shaped to a domed configuration and an incompressible rubber pad to impart a domed configuration to the member.  This method provides a far greater yield than conventional methods wherein an actuator is pressed between mating steel dies. Prior to the pressing operation the member may be pressed between the rubber pad and a die having an oppositely domed configuration to the first die.  The rubber pad may be mounted in a dolly movable between the dies.  An electrical contact may be applied to the member prior to pressing, and the pressing is carried out with the contact face down on the pad.  Subsequent to pressing, but prior to any temperature induced snap action, the curvature to the member is mechanically reversed with a plunger assembly, the distance moved in the reversal being accurately controlled since the mechanical reversal significantly affects the subsequent operating temperature of the actuator.

The improvement comprises subjecting the stream of 1,2-dichloroethane to a controlled prechlorination by contacting it with a chlorination agent selected from the group consisting of chlorine and aluminum chloride, wherein between 0.5 and 2 moles of chlorine chloride is utilized per mole of chloroprene, at a temperature of between 0°C. and 100°C., so as partially to chlorinate the chloroprene therein to produce one or more further chlorinated derivatives thereof;  separating the further chlorinated derivatives of chloroprene from the 1,2-dichloroethane;  and introducing the 1,2-dichloroethane substantially free of chloroprene or chlorinated derivatives thereof, into the ethylene chlorination reaction zone.  This process provides a more efficient utilization of the chlorination agent and production of more chlorinated product.
