Abstract: Abstract of the Disclosure A snubber apparatus which is constructed to present a high resistance to acceleration of the end fittings with respect to each other such as might occur due to seismic motion. The snubber apparatus preferably comprises a device which converts linear to rotary motion such as a ball screw and ball nut assembly which drives an inertia mass through a brake set and which when rotating causes braking to occur to increase the resistance force on the ball screw and ball nut assembly thus translating rotational resistance to linear resistance. The snubber apparatus is useful in restraining power plant piping, etc., in locations where earthquakes would be expected to occur.

Abstract: ABSTRACT OF THE DISCLOSURE        A portable power supply circuit for supplying a high voltage corona in a portable electrophotographic apparatus.           An A.C. signal comprising a series of pulses is produced by an oscillating circuit.  The pulses are shaped by a shaping circuit which draws current during only a portion of the operating cycle.  These pulses are coupled through a step-up transformer to a multiplying circuit which multiplies the voltage at its input to the desired corona voltage.  A control circuit senses the desired corona voltage and operates to inhibit passage of oscillations from the oscillating circuit to the pulse shaping circuit in order to minimize power consumption.

Abstract: ABSTRACT OF THE DISCLOSURE:      A load indicator is connected between a load line and a load handling member such as a hook.  The indicator includes a hollow cylindrical housing, a plunger assembly including a transverse head slidably mounted in the housing, a pilot rod integral with the head and extending to a location outside the housing, means connecting a first end of the housing which is opposite the plunger rod and means connecting the plunger rod to the load line and to the load handling member, and a compres-sion spring in the housing urging the plunger head toward the first end of the housing.  The wall of the housing has several sight openings therethrough.  A sight band of contrasting color is fixed to move with the plunger assembly inside the housing and to be visible through the sight openings.  The spring is of strength to allow sufficient movement of the sight band so that a first color just fills all of the sight openings when the load tensioning the load line, the indicator, and the load handling member reaches a predetermined rated value, and so that progressively less of the first color can be viewed through the sight openings as the tensioning load is reduced and the plunger head moves toward the first end of the housing.

Abstract: GAIN METHOD AND APPARATUS                   FOR A DELTA MODULATOR                   Abstract of the Disclosure In a delta modulator a sequence of code symbols are generated which are indicative of increments of signal level, with each code symbol being determined in accordance with the difference in signal level between an input signal and a prediction signal which is a representation of the input signal.  A sequence of the generated code symbols are stored, including the most recent code symbol and a preceding number of code symbols, with the pattern or code symbols at any instant defining a state of signal activity.          There is a table of delta increments, a table of threshold values, and a digital gain logic network, all of which provide signal outputs which are controlled by the state of signal activity represented by the stored code signal pattern.  The signal output from the delta table and the threshold table are modified an amount determined by the value of the signal output from the digital gain logic network.  An accumulation of modified delta increments are summed with modified threshold values for providing the prediction signal.  The prediction signal and the input signal are compared for generating a new code symbol.

Abstract: A CONTINUOUS BULK POLYMERISATION PROCESS               ABSTRACT OF THE DISCLOSURE         Copolymers of A  22 to 96 mol-% of styrene and/or .alpha.-methyl styrene, B   0 to 78 mol-% of at least one monoolefinically unsaturated monomer containing nitrile groups, and C   0 to 50 mol-% of at least one monoolefinically unsaturated monomer different from A or B are obtained by continuous bulk polymerisation in a homoge-neous liquid phase, in several process stages, in one or more different temperature ranges and in the presence of one or more initiators with different dissociation times in each temperature range and under pressures of from 1 to 20 bars.    In first stage the monomers are copolymerized with back-mixing up to a conversion of from 10 - 60 mol-% in an ideally mixed tank reactor and then after optionally additional addition of further parts of monomers copolymerization is continued with backmixing in a completely flooded, self-cleaning polymerization kneader up to a residual monomer content of from 10-50 mol-%.     Residual  monomers are continuously removed from the copolymer up to a content of less than 0.5% by weight based on the copolymer.     The process according to the invention provides uniform, compatible, homogeneous products which are free from gel-like particles and which combine improved transparency with greater dimensional stability under heat and better mechanical properties together with improved processibility.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for reforming and straightening damaged bodies and frames of vehicles whereby corrective forces are applied to the vehicles through one or more elongated force transmission elements.  A force is imposed on the elongated elements respectively by means of a uniquely mounted hydraulic ram which is freely pivotable sideways and limitedly pivotable in a backward direction. Each of the hydraulic rams are attached to a frame situated beneath the vehicle to be straightened whereby the frame further supports a measuring bridge coupled to the vehicle so that the progress of a straightening operation can be readily determined.  The measuring bridge includes vertical indicators which are coupled at datum points on the vehicle so that an operator can readily gauge the deformity of the vehicle longitudinally, laterally and vertically with respect to its center line.  An operator can gauge the progress of the straightening operation in conjunction with target elements which indicate the ultimate degree of straightening necessary to reform the vehicle.  The system thus permits a force to be applied to the vehicle in any desired direction or magnitude until such time as the measuring bridge indicates that the target dimensions have been reached providing a highly accurate and simplified technique of straightening and reforming vehicle bodies or frames.

Abstract: ABSTRACT       A charging and discharging circuit is formed by a PNP tran-sistor which is turned on by current flow through an isolating diode and a base bias network only when the input potential becomes higher than the reference potential, thereby closing a first charging path through a first resistor and another isolating diode to a common capacitor; an NPN transistor which is turned on by current flow through an isolating diode and a base bias network only when the input potential becomes lower than the reference potential, thereby closing a second charging path through a second resistor and another isolating diode to the common capacitor; and a third resistor connected across the common capacitor to provide a discharge path.  The "attack" time constants for inputs of positive and negative polarities are controlled by the first and second resistor values, respectively, and the "release" time constant is controlled by the third re-sistor value.  The circuit has utility in controlling a voice-actuated microphone in a hands-free intercom circuit, for ex-ample.
