Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus is disclosed for measuring battery temperature and battery voltage during battery charging.  The system is designed to charge a battery using two charging terminals and sensing battery voltage and temperature through the charging terminals.  In measuring the temperature of the battery, the battery is electrically isolated from the sensing circuit during a portion of the charging cycle where the charging voltage is less than the battery voltage.  Should the temperature of the battery, as measured, increase to a predetermined upper limit, the charging cycle is switched to a trickle charge on the battery.  The battery voltage is measured at the instant when charging voltage exceeds the battery voltage to give a true indication of the recharged potential of the battery. When the sensed battery voltage is at the desired level, charging is switched to trickle charge.  The system provides battery temperature and voltage sensing by the use of two terminal battery construction which is superior to the existing three and four terminal battery charging constructions.

Abstract: ABSTRACT OF THE DISCLOSURE       Arrangement for keyboards of the optoelectronic type which exhibit a surface area  (1)  in the form of a prism (16) divided up into fields (17). Each of the fields is allocated an individual control function. They are intended   to  be  contacted  at  the  respec-tive control function  by  a  surface  such  as  the  surface  of a  finger  tip.   This  causes  a  deflection  of  light,  which is produced  in the field in relation to the luminous flux in the prism when there is no contact with the surface. The variation in luminous  flux  is  supplied to a  light-detecting  sensor (19) by means of which an adequate command signal is generated. A control means (20) is so arranged as to produce a signal  specific to each field (17) and capable of being selected from the signals from other  fields.  A single element  or  a  small  number of  elements is/are provided as the  sensor element  (19). A signal processing means is also so arranged as to select the signal received from the  sensor  element  in  accordance  with  the  specific  signal characteristics  for  each of the  fields, and as to transmit an adequate  command signal for each field in accordance with said selection.

Abstract: ABSTRACT OF THE DISCLOSURE     TEST OPERATION OF ELECTRONIC DEMAND REGISTER     An electronic demand register performs rolling demand metering in which a demand interval is divided into N subintervals.  At the end of each subinterval, the demand data from the just-completed subinterval is summed with the demand in the most-recent N-1 contiguous subintervals to derive an interval demand.  A test operation is provided in which the stored maximum demand, a number representing the remainder of the subinterval interrupted by the test and programmed constants are stored in non-volatile memory but are also retained in the processor for use during test.  A test reset switch resets accumulated demand data and presets the subinterval timer to predetermined values from which they may be operated by a calibrated test load to confirm the performance of the demand register.  At the end of testing, all data in the processor is zeroed and the data stored in non-volatile memory is restored.  Demand metering is resumed starting with the remainder of the interrupted subinterval and with the demand from the N-1 prior subintervals set to zero.

Abstract: ABSTRACT An improved quick disconnect mechanism between a rotatable end yoke hub of a power take-off and a journal shaft is disclosed.  The hub has a central longitudinal passageway formed therethrough which is co-axial with the axis of rotation.  An aperture is formed completely through the hub in a direction which is generally perpendicular to the longitudinal axis of the hub.  The aperture extends at least partially through the passageway formed in the hub. One end of the aperture is formed with a reduced diameter portion, while an end plug is inserted through the other end of the aperture so as to close it.  The end plug includes a body portion sized to fit within the aperture and a head portion sized larger than the aperture.  The body portion includes an enlarged diameter portion formed thereon which is slightly larger than the inner diameter of the aperture so as to be frictionally engaged thereby.  The enlarged diameter portion may be formed as a circumferential projection, or alternatively as a thread. The head portion of the end plug is formed integrally with the body portion to permit rotation thereof during and after insertion.  The enlarged diameter portion cuts a shallow groove in the hub during such rotation to securely retain the end plug therein.  Prior to installing the end plug, a locking pin is slidably disposed in the aperture. The journal shaft is provided with a groove in the exterior surface thereof to receive the locking pin therein.  When the locking pin is inserted through the hub aperture and the journal shaft groove, it prevents the removal of the journal shaft from the hub.  The locking pin includes a recessed portion which, when aligned with the groove, permits the journal shaft to be removed from the hub.  A spring is provided to urge the locking pin to a position wherein the recess therein is not aligned with the journal shaft groove, thus normally preventing the removal of the journal shaft from the hub.  The portion of the slidable locking pin which extends outwardly from the hub is inclined (relative to the radii of the hub and journal shaft) in a direction away from the direction of rotation of the hub.

Abstract: SELF-SUPPORTED, ADJUSTABLE, CONDENSION-FREE SHOWER MIRROR      Abstract: A condensation-free, self-supported shower mirror assembly is heated by water dispersed into a temperature-control space behind the mirror.  The water is supplied by a supply tube connected from a showerhead pipe to a dispenser which disperses the heated water in either liquid or spray form, preferably from holes in a tube mounted in such temperature-control space.  Also the tube acts as a gasket to prevent the heated water from leaking through the front of the mirror. The back surface of the mirror is thereby heated to raise the temperature of the front surface of the mirror sufficiently to eliminate water condensation thereon.  In one version, mirror adjustment is accomplished through a single flex-joint, such as a hinge or a ball joint which is physically separated from the supply tube.  In a preferred version, mirror adjustment is accomplished through a flex-arm which allows rotatable and translational movement. Preferably the supply tube is carried inside the flex-arm; the supply tube is mounted by friction fit in the ends of the flex-arm.  The flex-arm is attached by break-away distal and proximal joints so that the parts will not be damaged in case of trauma.
