Title: Tank fill assist

IPC: B65D47/00
Filed: 1987-04-13
Granted: 1991-02-05
Abstract: ABSTRACT OF THE DISCLOSURE           A tank fill assist for filling a tank or other equiva-lent volume from a remote source of liquid, for example filling a consumer product from a sink or bathroom faucet with fresh water.          The fill assist is normally stowed within the interior of the tank.  It is withdrawn for connection to a faucet for tank fill-ing, and is then returned to stowed position after tank filling.          The fill assist comprises standard flexible conduit with unique inlet and outlet fittings at opposite ends.  The outlet fitting is disposed within the interior of the tank and is constructed and arranged to prevent accidental separation of the fill assist from the tank when the conduit is withdrawn from the tank yet to allow passage through the fill opening when it is intended to either join or separate the fill assist to or from the tank.  The inlet fitting is of thermoplastic rubber and can be fitted over the outlets of typical sink and bathroom faucets.  A retainer is disposed around the flexible conduit and is axially captured on the conduit between the inlet and outlet fittings.  The retainer forms a recepticle within which the inlet fittings nest when the fill assist is stowed.  The retainer in turn nests within the fill opening.  The retainer comprises apertures in its sidewall which provide an alternate fill path into the tank which is independent of the fill path through the conduit.  The retainer seats on par-tial internal screw threads formed on the inner wall of the fill opening so that the usual closure cap which has locking tabs which engage the partial screw threads can be screwed onto and off the fill opening in the usual manner without interference from the stowed fill assist.

The  leach  is  conducted  in  an acidic solution at a redox potential range which favours the dissolution  of  nickel  over  copper.    The  obtained  leach solution is purified in a cementation step carried out  at atmospheric  or  over-atmospheric  pressure  by  adding  more sulphidic matte or alloy particles.   The separated purified solution is treated for nickel recovery.   Any cobalt present in the sulphidic matte or alloy reports with the nickel.          Copper is recovered from the separated residue,  which will also retain precious metals if present.

Abstract: A B S T R A C T     It is foreseen to measure the rotational speed (v) of a motor (4) by measuring  the  electromotive  force   (e.m.f.).  This  e.m.f.   is calculated as the difference between the terminal voltage (Va) and the voltage drop at a reference resistor  (5),  through which the armature  current flows,  then this value  is  used  as  a  velocity feedback signal  for motor regulation.  Particularly,  the terminal voltage (Va) is cyclically measured at two successive close instants (t1, t2), during which the armature resistance  (Ri)  and the motor e.m.f. can be considered constant;  these  terminal voltage values (vat1,  Vat2)  are stored,  then elaborated to  perform  the  actual armature assistance  (Ri)  during that interval  (t1-t2),  then this value is multiplied for the instant current (I). The result is then subtracted from the terminal voltage (Va) and only at that time the resulting  e.m.f.  is used as a velocity  feedback signal  for the velocity feedback circuit.   The apparatus for carrying out this process is also disclosed.

Title: Innerseal capable of indicating heat tampering
Inventor: EMSLANDER JEFFREY O
IPC: B65D53/04
Filed: 1987-10-07
Granted: 1993-06-29
Abstract: Abstract of the Disclosure This invention relates to innerseals for containers which will provide a visual indication, before use, as to whether the innerseal has been the subject of tampering.       Certain kinds of innerseals can be removed from the mouths of containers by heating the innerseal to weaken the bond between the innerseal and container mouth and then carefully peeling the loosened innerseal away from the mouth of the container. The contents of the container can then be adulterated, and the innerseal resealed to the container mouth.  Another method of tampering involves the steps of removing the innerseal from the mouth of a container having a relatively large diameter, cutting a disk out of the removed innerseal so that the disk is of a diameter suitable for covering the mouth of a container having a relatively small diameter, and heat sealing the altered disk to the mouth of the smaller container.         This invention provides an innerseal for bottles or other containers comprising a facing layer, an insulating layer adhered to one major surface of said facing layer, and a thermally sensitive layer adhered to said insulating layer.  In a second embodiment, the innerseal comprises a facing layer and a thermally sensitive layer adhered to said facing layer.  Upon application of a sufficient amount of heat to the thermally sensitive layer, said layer will change its appearance in such a way as to provide an indication of tampering by means of heat.

Abstract: POLYSILANE PRECERAMIC POLYMERS                          ABSTRACT           Chlorine or bromine-containing polysilanes of the general formula (R2Si)(RSi)(R'Si) are disclosed.  In these polysilanes, there are also bonded to the silicon atoms other silicon atoms and chlorine or bromine atoms, R is an alkyl radical containing 1 to 4 carbon atoms, and R' is selected from the group consisting of alkyl radicals of at least six carbon atoms, phenyl radicals, and radicals of the formula AyX(3-y)Si(CH2)z- wherein each A is independently selected from a hydrogen atom or alkyl radicals containing 1 to 4 carbon atoms, y is an integer egual to 0 to 3, X is chlorine or bromine, and z is an integer greater than or equal to 1. These preceramic polymers can be pyrolyzed at elevated temperatures under an inert atmosphere to yield ceramic materials or articles.  These polysilanes may also be converted into other preceramic polymers which can be pyrolyzed to ceramic materials or articles.
