Abstract: ABSTRACT OF THE DISCLOSURE         A protective casing for a lamp holder for outdoor use comprises a cylindrical part and a bowl-shaped base part which are made of a relatively soft,elastic material and can be clamped axially together around an ordinary lamp holder.  The engagement faces between the two parts are formed with radial recesses, which together form a hole for the lead-in of a cable and are dimensioned so that the cable is fixed upon clamping.  This provides a seal for the cable lead-in and also tension relief of the cable. Owing to the clamping, a sealing ring for the lamp is dis-posed between an end edge of the holder and a rim flange of the cylindrical part.

Abstract: CONTROL SYSTEM FOR TIMING HAMMERS OF IMPACT PRINTERS     Abstract of the Disclosure A hammer timing control system for a line printer has a register for continually storing a digital delay fire quantity representative of the actual flight of a controlled hammer.  A delay fire counter activated by an initiate fire pulse from hammer selection circuitry of the printer control system counts the timing pulses from a clock means until it registers a count equal to the delay quantity stored in the delay fire register. A comparator circuit is connected to both the delay value register and the counter and generates a hammer fire signal when the delay quantity and the count are equal.  The single counter continues counting clock pulses until a second count is registered which is equal to a terminate fire value.  The control system provides circuit means responsive to the second count registered in the counter to terminate the hammer fire signal.  In one embodiment, the terminate fire circuitry comprises a decode connected to the output of the counter means for detecting the second count condition.  In a second embodiment, the control system has a second register which stores a terminate fire quantity which represents a fixed time after the initiate fire signal and prior to hammer impact.  In a third embodiment, the counter is an up/down counter which counts in one direction to turn on the hammer driver circuit and in the other direction to turn off the hammer driver circuit.  The delay fire quantities for the plurality of hammers are preferably stored in an external memory device for transfer to the individual registers for each of the print hammers. The external storage may be a magnetic record such as a disk.

Abstract: ABSTRACT             This invention distinguishes coins by electronically checking their various masses, diameters and thicknesses.  The coins are subjected to a constant acceleration force, i.e., gravity, and slide along a side of a ramp, which results in different velocities for different kinds of coins.          The speeds of the coin are measured at two different times at one location on the ramp, or alternatively at two different adjacent locations along the ramp.  The width and thickness of the coin are also measured.  It has been found that an accurate determination can be made of the designation of the coin based on correspondence between the acceleration (which is related to the mass), the width (which is specifically the diameter of a round coin), and the thickness, or a proportional section of the width and thickness with predetermined ranges of acceleration, width and thickness.

Abstract: "RECOVERY OF AROMATIC HYDROCARBONS AND A NON-AROMATIC  RAFFINATE STREAM FROM A HYDROCARBON CHARGE STOCK"                                 ABSTRACT           A process for the recovery of aromatic hydrocarbons and a non-aromatic raffinate stream from a hydrocarbon charge stock is dis-closed.  The hydrocarbon charge stock is treated with an aromatics-selective solvent to provide an aromatics-rich solvent stream and a non-aromatic raffinate stream.  The aromatics-rich solvent stream is treated in a stripper column at conditions to separate substantially all of the non-aromatic hydrocarbons therefrom.  The rich solvent stream is subjected to steam stripping to provide a high purity aro-matics stream and an aqueous stream comprising the steam condensate and residual aromatics.  This aqueous stream is treated with a minor portion of the non-aromatic raffinate to remove the residual aroma-tics, and the resulting aqueous stream is utilized to wash the re-mainder of the raffinate free of solvent.  The raffinate stream is recovered substantially  free of aromatics.

Abstract: BOILER FEED WATER DEAERATOR SPRAY VALVE TURBULENCE SHIELD     Abstract of the Disclosure An improved boiler feed water deaerator is provided which includes a plurality of spray valve assemblies therein which are shielded to effectively eliminate undesirable valve chattering and vibra-tions resulting from the horizontal component of incoming feed water and turbulent water flow through the valves.  The valves hereof include an elongated, tubular, open ended water flow-direct-ing shield with a shiftable valve plug adjacent the outlet end thereof.  The plug is secured to an elongated stem disposed axially within the shield, and support structure is provided for the stem adjacent the upper inlet of the shield for permitting reciprocation and limited pivoting movement of the stem and plug.  The ratio of the internal diameter to the length of the shield is desirably less than about 2 (most preferably about 1) in order of assure that water entering the inlet end of the body is directed substantially axially prior to discharge; this has been found to measurably reduce turbulence in the water and hence minimize potentially destructive valve vibration.

Abstract: ABSTRACT OF THE DISCLOSURE          Glued laminated wood which has a novel laminated structure and may be fabricated from small-sized veneer sheets, and method of manufacturing such laminated wood are provided.  The glued laminated wood in its continuous form is made from a series of unit-length veneer sheets each having the same length and thickness which are lamina-ted in a laid-up arrangement in which each of the veneer sheets is lapped on another and offset therefrom in the direction of its length at a regular interval determined by the number of plies to be in the laminated wood products and the length of the unit veneer sheets.  It has a novel structure in that each veneer sheet therein has tandemly spaced straight length portions which are parallel to each other, but successively displaced from each other in the direction of the thickness of the product, there being a somewhat S-shaped curved length portion of the veneer sheet between any successive pair of these straight length portions.        The number of such straight length portions in each unit veneer sheet is equal to the number of plies in the glued laminated wood being made, and the length of each such straight length portion is nominally determined by dividing the length of the unit veneer sheet by the number of plies.

Abstract: TIMING DELAY EQUALIZATION CIRCUIT            Abstract A circuit for generating a common signal as a function of either of two reference signals comprises a pair of phase-locked loops which share an oscillator.  Each phase-locked loop generates a control signal as a function of one of the reference signals.  One or the other of the control signals is coupled to the oscillator which generates the common signal.  A comparator compares the two control signals and generates a signal indicative of their difference.  While the control signal generated by the first phase-locked loop is coupled to the oscillator, the difference signal is applied to the second phase-locked loop where it controls the generation of the second control signal to minimize the difference between the two control signals.  While the control signal generated by the second phase-locked loop is coupled to the oscillator, the second phase-locked loop is nonresponsive to the difference signal.  Thus when a switch of reference signals occurs even if they are of different phase and even if that phase is slowly time-varying, the circuit can lock to the new reference signal at a phase dictated by the phase difference between the two references at the instant of the switch without causing the oscillator output to undergo significant frequency or phase changes.
