Abstract: TAMPER-RESISTANT ELECTRICAL METER HOUSING     ABSTRACT A tamper-resistant electrical meter housing includes an unbreakable cover assembly that cooperates with a matable base to enclose a meter device supportable on the base.  The cover assembly includes an annular ring secured to the cover. A locking leaf spring is coupled to the cover assembly.  The leaf spring is aligned to slide along the top of a rim portion of the base and snap into a recess to lock the cover assembly against rotation and removal.  Once the cover assembly is locked to the base, the leaf spring is substantially con-cealed from view, so that an unauthorized person cannot effect removal of the cover to obtain access to the meter.  The base also includes a specific area in alignment with the recess, which area is identifiable only by an authorized person.  A hole may be drilled in this area by an authorized person and a tool may then be inserted through this hole to effect dis-engagement of the leaf spring and removal of the cover assembly from the base.

Abstract: KNIFE SHARPENER                 ABSTRACT OF THE DISCLOSURE    A knife sharpener comprises at least a pair of identical subassemblies and a cooperating housing.  Each subassembly includes a planar base member with a pintle shaft projecting obliquely therefrom.  An abrasive roller or grinding wheel is journaled on the pintle.  Pairs of the subassemblies are arranged in opposed complementary relationship with each other such that the rollers are adjacent each other and angulated to define a passageway through which a knife blade may be drawn for being abraded and sharpened on each side simultaneously by the rollers.  Stop means comprising projections from the interior of the housing restrain the rollers on the pintles.  The base members are held in complementary relationship with double faced pressure sensitive adhesive strips one face of which adheres to the base members and the other face of which may be pressed on to a mounting surface.  The housing makes a press fit with the base members and can be easily removed for cleaning and for inverting the rollers when their original cooperating peripheries become worn.          Another embodiment provides for mounting the knife sharpener with a suction device.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method of treating sewage is disclosed.  The apparatus includes a modular treating tank which is divided by a perforated baffle or screen into primary and mixing chambers.  The mixing zone has a curved or semi-sperical end wall.  A mixing and aeration system utilizing a high efficiency ejector withdraws liquid from the mixing chamber and di-rects the recirculated flow toward the primary chamber across the perfora-ted baffle.  In this way, a general circular flow pattern is established from the mixing chamber to the primary chamber across the baffle and return. Thus larger solids are maintained in the primary chamber and are subject to substantially complete organic decomposition therein.  The effluent from the treating tank is subsequently chemically disinfected by timed, periodic addition of a chemical e.g. a selected halogen.  The method includes the establishment of a recirculating generally oval or circular flow pattern in which liquid is withdrawn from the mixing zone, is aerated and is direc-ted toward the primary chamber.  Substantially complete mixing with the in-coming sewage occurs in the primary chamber to maintain a uniform concen-tration of oxygen, feed and purifying organisms throughout the tank volume.          By these means, satisfactory treatment results are obtained in reduced time, and high solid concentrations can be maintained in suspension.  Sludge is almost completely oxidized, so that little or no sludge accumulates or must be withdrawn from the system for disposal.
