Patent CA-2007969-C (CA)
Inventor: BUNZ GEORG
IPC: A44C11/02
Filed: 1990-01-17
Granted: 1998-03-31
Abstract: A plug-type clasp for pieces of jewelry, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring.  The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there.  Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order.  Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp. With the exception of the spring and sleeve, no other movable parts are required.

Title: Sealing closure cap
Inventor: MACARTNEY CHARLES T
IPC: B65D41/04
Filed: 1990-11-22
Granted: 1993-10-05
Abstract: ABSTRACT OF THE DISCLOSURE A polyethylene cap,  for use with containers, particu-larly polypropylene containers for containing medical speci-mens in preservative fluid such as formaldehyde, is provided with a 3-face seal, wherein a rim portion of the container is trapped in  sealing,  contacting  relation on  three mutually adjoining faces, whereby any tendency of the container rim to "relax" out of sealing engagement with a contacting face por-tion of the cap is effectively precluded by the geometry of the cap seal.  In the case of polypropylene, which is suscept-ible to such "relaxation", the subject cap enables the effect-ive sealing of polypropylene containers so that advantage may be taken of the superior properties of polypropylene in non-reactive, secure containment of possibly contaminated medical specimens in liquids such as formaldehyde, a known carcinogen. In a preferred embodiment the cap has a "feel" element,  to give actual indication of engagement.

Title: Battery state of charge indicator
Inventor: LAMBERT JOE C
IPC: G01R31/36
Filed: 1991-05-09
Granted: 2002-07-16
Abstract: A method for measuring and storing the state of charge of batteries, such as used in electric vehicles. The stored charge value is initially derived from the value of battery terminal voltage measured prior to connection of the battery to the load, eg. the traction motor. While the battery is connected to the load, approximated state of charge values are periodically derived by adding a correction voltage, comprising the product of measured load current and of a predetermined value of internal resistance, to the measured terminal voltage of the battery. The stored and approximated state of charge values are periodically compared and the stored state of charge value is decremented by a predetermined increment in response to the stored charge value having exceeded the approximated state of charge value during each of a predetermined plurality of consecutive comparisons.

Granted: 2002-05-21
Abstract: A housing for a protective plug including a surge arrester is composed of a pedestal-like lower portion and of an upper portion which is joined of one piece thereto via film hinges. The upper portion is preferably composed of two halves that, for closing the protective plug housing are pivoted towards one another and mechanically joined to one another by appropriate interlock elements. The lower portion contains receptacle chambers for contacts that, proceeding from a base, comprise a double spring contact downwardly in the plug-in direction and a clamp terminal in the upward direction. Three identical contacts are present that are each respectively connected via their clamp terminals to terminal pins of the surge arrester. A pin-shaped projection extends from the upper side of a distributor strip to serve as cooperating contacts for the double spring contacts. Each such contact also has a pin-shaped projection extending from the bottom side for connection to switching equipment. Also, such pin-shaped contacts may be insulation-pierce contacts.  The contact element comprises an offset between the center line of the double spring contact and the actual terminal of the terminal legs of the surge arrester that are in alignment. Given receptacle chambers that are arranged offset relative to one another, the surge arrester can be introduced thereinto on a straight line without a deformation of its terminal legs adapted thereto when the individual contact elements are introduced into the receptacle chambers in a defined, mutually turned position.

Title: Flow-inducing panels for electroless copper plating of complex assemblies
Inventor: FORSYTH MARK R
IPC: C23C18/31
Filed: 1992-08-24
Granted: 1997-12-23
Abstract: Flow-inducing panels for use in electroless copper plating of complex plastic microwave assemblies. A panel comprises a rigid baffle having openings adapted to secure microwave assemblies therein. The panel has a size relative to the electroless copper plating tank that causes sufficient plating solution flow through the channels in the microwave assemblies by minimizing solution flow bypassing of the channels. This achieves complete copper plating of the inner surfaces in the channels. A relatively large panel builds up back pressure as it approaches plating tank walls, which creates a pressure differential as it moves through the plating tank, thus forcing solution through the channels. The flow-inducing panels easily hold many parts in a stabilized manner which yields high productivity, and provide solution flow through the channels using a standard metallization basket used for printed wiring board manufacturing.
