Granted: 1993-03-30
Abstract: LIGHT ATTACHABLE TO A KEY               ABSTRACT OF THE DISCLOSURE An improved light attachable to a key is pro-vided with a housing and back plate having substantially similar widths between which is secured the head portion of a key.  The housing encases a frame formed with reces-ses to accept a battery, light bulb, contacts and a switch.  The frame fits into the back side of the housing such that a flat back side is formed which allows the head of a key which abuts the back side of the housing to overhang the width of the housing.  The back plate attaches to the housing by means of a rectangular tab on one edge of the back plate which engages a correspond-ingly shaped groove in the housing, and by means of a screw from the face of the housing through a hole in the head of the key to the face of the back plate.  The back plate is formed so as to have three open sides to similarly allow the head of the key to overhang its width.  The key is held in place by the clamping force between the housing and the back plate provided by the screw, and also adhesive material disposed on the back plate to affix the key head to the back plate.  Option-ally, a bore is provided in the housing and frame to receive and carry a screwdriver used to tighten or re-move the screw.

Title: Process for the recovery of halogenated hydrocarbons in a gas stream
Inventor: FILIPOVIC DUSANKA
IPC: B01J8/02
Filed: 1988-03-03
Granted: 1998-04-21
Abstract: A process for the recovery of halogenated hydrocarbons from a gas stream comprises passing the gas stream through a bed of hydrophobic molecular sieve adsorbent, preferably of the high silica zeolite type. Such adsorbent has pore diameters large enough to permit molecules of the halogenated hydrocarbons to pass therethrough and be selectively adsorbed in the large internal cavities of the crystal framework, whereby the halogenated hydrocarbons are removed.  The gas is continued to be passed through the bed of adsorbent material until the material is saturated to the extent that breakthrough of the hydrocarbons is determined. The adsorbent material with adsorb phase of halogenated hydrocarbons is removed from the machine and regenerated by exposing the saturated material to an inert purging gas stream under conditions which desorb the halogenated hydrocarbons from the adsorbent material into the purging gas stream.  The halogenated hydrocarbons are then removed from the purging gas stream and purified to a purity for reuse of the recovered halogenated hydrocarbons.

Inventor: GANDHI DEEPAKKUMAR J
IPC: H02K1/16
Filed: 1988-03-10
Granted: 1991-10-01
Abstract: LIP STRUCTURE FOR A STATOR IN A DYNAMO-ELECTRIC MACHINE       ABSTRACT OF THE DISCLOSURE     Laminations used in a lamination stack to form a stator of a dynamo-electric machine, have a number of circumferentially spaced slot openings extending radially outward from an inner circumference of a bore opening in each of the plates.  The mouths of the slot openings are wide enough to receive a stator winding when inserted between teeth which bound the slot openings.  Each tooth has a main body part and a pair of lip parts at a distal end, with each lip part protecting circumferentially into the mouth of a respective slot opening adjacent the tooth.          An edge of each lip part projects from the main body part to retain the stator winding, the edge defining a slope angle with respect to a line perpendicular to the center line of the slot opening into which the lip part projects.          The slope angle is functionally related to the width of the main body part of the teeth.

Abstract: WET PRESS ABSTRACT OF THE DISCLOSURE A paper machine includes a double-felt (or single-felt) wet press.  Two press elements, for instance two rolls, whose axes lie in a press plane, form a press nip with each other.  Two endless felt belts, and between them the paper web from which the water is to be removed, pass through said nip.  Beyond the press nip the paper web travels, free of the felt belts, to the next station of the paper machine.  Each of the two felt belts travels beyond the press nip over a guide element, preferably a guide roll, whose position is displaceable parallel to the press plane. The arrangement is operated as follows:  The angle between the paper web and the wetter felt is set to a smaller value during the initial licking-up process than during the subsequent continuous operation.  On the other hand, the angle between the paper web and the drier felt is set to a larger value during the initial licking-up process than during the subsequent continuous operation.

Title: Plate heat exchanger
Inventor: DAHLGREN ARTHUR
IPC: F28F13/08
Filed: 1988-04-20
Granted: 1992-05-19
Abstract: Abstract In a plate heat exchanger, the heat exchange plates of which have been provided by pressing with a corrugated pattern comprising ridges and valleys, the ridges and valleys of adjacent plates extend in parallel.  In each plate interspace the ridges of adjacent plates abut against each other such that the opposing valleys form parallel flow passages in the plate interspace.  The ridges of at least some of the heat exchange plates are provided with depressions, which form thresholds in the valleys formed on the opposite sides of the plates by the ridges.  Thresholds of this kind can be formed in the heat exchange plates such that they create a substantially larger flow resistance in the plate interspace for one heat exchange medium than in the plate interspaces for the other heat exchange medium.

Title: Remotely controllable circuit breaker with improved arc drive structure
Inventor: YOKOYAMA YOUICHI
IPC: H01H71/66
Filed: 1989-01-11
Granted: 1992-01-14
Abstract: ABSTRACT   A remotely controllable circuit breaker has an improved scheme for effecting rapid arc extinction as well as protecting the breaker contact from the resulting arc current.  The breaker includes first and second movable contacts    and    which are held respectively on parallel extending first and second contact arms    and    and are driven individually by a switching mechanism    including a manual handle    with a contact trip capability and by a remotely controllable switch   .  An arc runner     is connected to be in the same electrical potential as the second contact arm    and extends in the contact separating direction for receiving the one end of the arc developed between the rapidly separating contacts    and    and guiding the arc toward an arc extinguishing chute     as the first contact    moves away from the second contact   .  The arc runner     is connected at its end opposite to the arc chute     to an arc drive member     which extends immediately behind the second contact arm    in parallel relation thereto and is cooperative with the first contact arm    to develop electromagnetic repulsion forces therebetween upon the occurrence of the arc by the effect of the current flowing through the first contact arm    and the arc drive member     in the opposite directions.  The repulsion force acts to urge the arc toward the arc chute for rapid arc extinction.   At this time, the arc current will bypass the second contact arm    for protecting it from the overcurrent.

Title: Portable water-purifying devices
Inventor: MEAD ROBERT JAMES
IPC: C02F1/76
Filed: 1989-02-27
Granted: 1995-12-05
Abstract: A portable water-purifying device comprises a primary disinfecting chamber      and a combined secondary disinfecting chamber and post-filter Water to be purified can be scooped by means of a cover into a receptacle   containing a pre-filter media      of preferably silvered activated carbon beneath a coarse entry filter pad      .  From that receptacle      the water enters the primary disinfecting chamber     , flowing downwards through nine or so passage-forming segments      filled with a microbiocide     , to effect primary disinfection, that is, to kill a substantial number of pathogenic organisms, but probably not all.  Each passage      is at least three times longer than it is wide, to prevent channelling of the water through the microbiocide.          Disinfectant from the microbiocide      enters the water as it passes through.  The disinfectant-containing water from the primary disinfecting chamber      enters the combined secondary disinfecting chamber and post-filter - "second chamber      " - down a centre tube to be stored for, say, two minutes or so for any remaining viruses, as well as any other remaining pathogenic organisms, to be killed.  The second chamber is then inverted, whereupon the water flows through a charge media      of preferably silvered granular activated carbon which effects post-filtration, substantially removing the disinfectant from the water, which flows thence into a drinking cup
