Abstract: ZINC HALOGEN BATTERY ELECTROLYTE  COMPOSITION WITH LEAD ADDITIVE            ABSTRACT OF THE DISCLOSURE        This disclosure relates to a zinc halogen battery electrolyte composition containing an additive providing improved zinc-on-zinc recyclability.   The improved elecbrolyte composition involves the use of a lead additive to inhibit undesirable irregular plating and reduce nodular or dendritic growth on the electrode surface.   The lead-containing electro-lyte composition of the present invention appears to influence not only the morphology of the base plate zinc, but also the morphology of the zinc-on-zinc replate.   In addition, such lead-containing electrolyte compositions appear to reduce hydrogen formation.

Abstract: ABSTRACT         A multi-channel EBAL apparatus and method of operation employing a plurality of parallel operated electron beam channels with each electron beam channel being of the fly's eye array optics type having an electron gun for producing an electron beam, an array lenslet assembly and an associated fine deflector assembly together with a coarse deflector for selectively direct-ing the electron beam to a desired array lenslet within the array lenslet assembly.  The associated fine deflector element there-after directs the electron beam to a desired point on a target surface such as a target semiconductor wafer being processed by electron beam lithography.  A common movable stage is provided for supporting the target wafer surfaces below the plurality of parallel operated electron beam channels and for moving the target surfaces in common relative to the array optics axes of all of the electron beam channels.  Common movement of all of the target surfaces is achieved automatically in preprogrammed manner preferably along either axis of an x-y translation mechanism.  All of the electron beam channels are supported within a common housing which is evacuated along with the movable target platform which serves to move the target surfaces in common.  The apparatus can be employed in conjunction with a pattern registration grid formed by means of a lenslet calibration grid and which provides fiducial marking signals for identifying the boundaries of the field of view of the respective lenslets in each electron beam channel as well as the field of view of all of the electron beam channels and for stitching together the required number of the fields of view to thereby cover a desired area of a target surface.          Provision is made for accommodating the occurrence of any flawed lenslet assemblies by permuting the target surface so as to place any portion of a target surface that had been subject to a flawed lenslet to the view of an unflawed lenslet for subsequent electron beam treatment.  Increased production capacity can be obtained by connecting a plurality of such EBAL apparatuses in parallel and controlling them in common by an overall system executive computer.

Abstract: 14828 The invention relates to a solar energy conversion apparatus in which several evacuated, glass tubular collectors are connected together in a liquid circulation system for controlled movement of a liquid between the interior of the collectors and a storage tank. Liquid circulation is controlled by sensors and switches therefor in regulating operation of valves and/or a pump. The conditions for circulating the liquid rely upon (1) sensing a need for energy at the storage tank, (2) sensing solar radiation availability, (3) sensing thermal conditions in the solar collector tubes to avoid high temperature and thermal shock, and sensing a need to withdraw hot liquid and add more. The system is operable in either of two modes herein disclosed: (a) the "continuous batch circulation" mode in which liquid is pumped to fill the tubes, in parallel, and low temperature sensed below a set point to stop pumping and resume pumping when the temperature in the tubes arrives at the preselected higher temperature, and (b) the "full continuous circulation" mode in which liquid is continuously pumped through the tube collectors, in parallel, continuously withdrawing liquid from the top of the tube while introducing liquid at the bottom of the tube; in either mode, the hotter liquid being removed from the top of the tubes and relatively colder liquid introduced at the bottom of the tubes.

Abstract: Abstract Method and apparatus are disclosed for communicating utility usage information from a utility usage location to a portable utility usage registering device (22).  A utility usage detection circuit (10) is provided at the utility usage location.  The circuit is connectable to a conventional utility meter (12), e.g., a natural gas meter, and provides an electrical signal indicative of utility usage.  This signal is applied across a first inductive coil (23), which is mounted at the utility usage location such that the resulting magnetic field is accessible.  A matching coil (36) is associated with the portable utility usage registering device and is housed such that it may be positioned within the magnetic field produced by the first inductive coil.  When thus positioned the electrical signal produced by the circuit (10) is induced in the matching coil as a result of mutual inductance between the two coils.  The electrical signal is thus communicated to the portable utility usage registering device without utilizing conventional electrical connectors, which are susceptible to corrosion, dirt contamination, etc.

Abstract: ABSTRACT OF THE DISCLOSURE       A branched chain polyalkylenepolyamine ("PAPA") amine having plural amine groups including a secondary amine group intermediate terminal primary amine groups and having at least two carbon atoms between each amine group, is reductively alkylated with a ketone to provide a PAPA alkylated only at an unhindered primary amine group. A preselected degree of steric hindrance at amine groups near each end of the chain enables cyclization by the 'ketoform synthesis' by reaction with a ketone in such a manner as to form a polysubstituted piperazinone ("PSP") ring which includes N atoms of proximate primary and secondary amine groups of the alkylated PAPA. The PSP so formed may then be reacted with a reactive triazine ring so that a PSP substituent is linked to the triazine ring through a single N atom and at least two C atoms, to form a 2-oxo-piperazinyl-triazine ("PIP-T"). Oligomers of the PIP-T may be prepared. The PIP-T compounds are excellent stabilizers against ultraviolet (uv) light degradation in light-sensitive synthetic resinous materials.
