Patent CA-2103415-A1 (CA)
Title: Method and apparatus for providing wire support for an electric lamp
Inventor: LIESZKOVSZKY LASZLO V
IPC: H01K1/18
Filed: 1993-11-18
Abstract: METHOD AND APPARATUS FOR PROVIDING  WIRE SUPPORT FOR AN ELECTRIC LAMP                         ABSTRACT OF THE INVENTION An electric lamp having improved wire support features includes a light source having leads extending therefrom. The light source leads are connected to conductor wires which are effective for providing conduction of energy to the light source and for providing a means to mechanically support the light source in an outer jacket. A support member made of an electrically insulative material is connected between the conductor wires in order to control and define the geometry of the conductor wires during the manufacturing process and to enhance rigidity of the frame formed by the conductor wires thereby preventing damage to the light source as can occur under certain excessive forces caused by shock and vibration that are exerted on the light product. The support member is achieved by use of a resistor blank which is adaptable to high speed manufacturing operations at very cost effective values.

Inventor: COVER WALTER E
IPC: A61M5/31
Filed: 1994-11-14
Abstract: Leakage of blood from the insertion set, during and after safety-needle retraction, is suppressed by components that receive and retain flash blood for viewing -- notwithstanding forces developed within the device in retraction.  One preferred such system includes a flash chamber that moves with the retracting needle, within a hollow handle, carrying a relatively high flow-impedance element which allows air exhaust from the chamber into the handle to admit flash blood -- but isolates blood in the chamber from retraction-generated increase in air pressure in the handle.  Energy-absorbing components control or compensate for retraction speed, to provide quiet smooth retraction -- while yet enabling use of ample retraction force to make retraction reliable.  Among several energy absorbing systems disclosed is a preferred one that includes a viscous material introduced within the hollow handle to damp the retracting motion; and an injection port to facilitate introduction of the viscous material.  Needle reuse, and concomitant risk of spreading disease, are avoided through components that deter needle redeployment -- by deterring access to or forward motion of the needle, or trigger reengagement.
