Title: Multiple rate electrical energy metering system and  method
Inventor: GERMER WARREN R
IPC: G01R11/32
Filed: 1980-11-21
Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE         An electronic time-of-day metering system is disclosed for measuring electrical power by at least two different mechanical recording devices depending on the time-of-day and time of week in which the electrical power is being consumed.  A conventional kilowatt hour meter includes a set of decade gear drive dials which register the kilowatt hours consumed on a continuous basis.  At least one other set of decade sear driven dials is provied for registering the consumption of kilowatt hours during preselected peak power usage inter-vals.  A single MOS integrated circuit controls the operation of the alternate set of decade gear driven dials.  This circuit utilizes as its time base the 60 Hz line voltage derived from the energy distribution system being metered.  A clock circuit generates timing signals for a clock control circuit which includes a circulatory memory which is preprogrammed to contain the times at which one or more alternate sets of dials are to be actuated.          When the clock time equals a stored time a gating signal is generated.  At the same time a function command signal, also stored in the circulatory memory, is passed through the enabled gate for engaging or disengaging the alternate set of decade gear drive dials, depending on the value of the function stored.  The gated signal controls the energization of a bistable clutch which engages the alternate set of dials.  A method for register-ing total energy consumed by a metered system as well as energy consumed during preselected time intervals is also disclosed. disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is disclosed for preparing a mixture of hydroxyl-containing di- and trisulfides, from either 2-mercaptoethanol or 3-mercaptopropanol, directly in two steps, without the formation of deleterious byproducts. Precise control if process conditions (a) in a first step in which the disulfideis formed, includes oxidation of mercapto-lower alkanol with a stoichiometric amount of H2O2 while maintaining the pH and temperature of a relatively dilute aqueous reaction mixture within a specific narrow range; and, (b) in a second step in which a predetermined portion of the disulfide is converted substantially exclusively to the trisulfide, requires controlled heating of the reaction mixture to a temperature not to exceed 100°C.  The process may be carried out in a single reaction vessel, and directly yields a preselected distribution of disulfide and trisulfide in the mixture.  The mixture is especially useful as a chain terminator in the preparation of hydroxyl-terminated liquid polymers having an aliphatic polymeric backbone and sulfide linkages near the terminal portions of the polymer molecule (referrred to as "HTPS" polymers).

Abstract: ABSTRACT           The present invention is with respect to cooled rolls, and more specially distributor rolls with a metallic outer face for the transport of ink or dampening fluid in offset presses.   The even temperature distribution over the full press width necessary for printing without any trouble conditions is more specially likely to come to an end when the press is shut down for a short time and when the dampening system is turned off.   The heat transfer then taking place from the relatively hot press side frames, the driving and the bearing parts to the cooler roll bodies is responsible for trouble conditions, caused by uneven temperature distribution, when the machine is started up again.

Abstract: A REUSABLE, MODULAR, KNOCKDOWN CONTAINER                          Abstract An improved, reusable, modular, knockdown container preserves delicate corners necessary for providing sufficient bearing surface and force direction to maintain the package erect by providing a clip bearing plate associated with each corner to protect the corner during placement and removal of the clip from the container.  Notched, interfitting panels are held erect by a resilient clip which fits into routed troughs on adjacent panels. A clip-receiving recess ensures that the clip does not extend upwardly from the surface of the panel.  Access means through the clip allow insertion of a bar to wedge between the bearing plate and the clip in prying the clip from its position holding the adjacent panels.  Thus the life of the panel is substantially increased.

Abstract: PHB. 32,785.           ABSTRACT:     In order to reduce signal loss particularly when transmitting data in a quasi-synchronous area coverage scheme utilizing sideband diversity it is necessary to effect coherent demodulation by looking the local oscillator signal to the received carrier signal, even when the carrier has been completely suppressed.  The demodulator disclosed com-prises first and second mixers having first inputs to which a frequency converted input signal having sideband diversity is applied.  Second inputs of the first and second mixers receive a local oscillator signal.  Phase shifting is applied to the input or local oscillator signal so that the outputs of the first and second mixers have a relative phase differ-ence of 90°.  The outputs of the first and second mixers are applied to respective audio bandpass filters the outputs of which are mixed in a further mixer to provide a sideband error signal (Es) which is low pass filtered in a filter.  A carrier signal (Ec) is derived by low pass filtering the output of the first mixer.  A composite error signal Ecs is produced from the two error signals (Es and Ec) and is applied to either the local oscillator to lock its fre-quency and phase to the input signal or to a local oscillator of a prededing frequency conversion stage.  In operation when the radio frequency phase angle .PHI. approaches 180° then the phase reference tracks across from a stable null at 0° to another stable null at 90°.  The stable null tracks at 180° for values .PHI. of 270° and greater.
