Title: Safety lock for the doors of electrical appliances
Inventor: ONDERKA OSWALD
IPC: H01H3/16
Filed: 1990-04-12
Granted: 1995-07-11
Abstract: A safety door lock for a door of an electrical appliance to selectively enable or disable operation of the electrical appliance includes a longitudinally displaceable detent bolt mounted in a door of an appliance, the detent bolt including a free end having a detent recess, a door lock housing having an opening adapted for receiving the free end of the detent bolt, and a switching slide which is longitudinally displace-able along a longitudinal axis and which is mounted in the door lock housing.  The switching slide is oriented such that longitudinal displacement of the detent bolt toward the switching slide brings the detent bolt into engagement with the switching slide, the switching slide having a stub end adapted to engage with the free end of the detent bolt.          After engagement of the end of the detent bolt with the stub end of the switching slide, further longitudinal displacement of the detent bolt in a direction toward the switching slide causes movement of the switching slide to its "on" position.          A biasing means urges the switching slide toward an "off" position in which the appliance is disabled, and a detent means latches the free end of the detent bolt in a locking position within the door lock housing upon insertion of the detent bolt in the door lock housing and for locking the switching slide in its "off" position when the end of the detent bolt is not inserted in the door lock housing.  The detent means includes at least one releasable locking latch which clamps the stub end of the switching slide in the "on" position of the switching slide, to prevent longitudinal movement of the switching slide, and the locking latch is movable in a direction which is generally radial to the longitudinal axis.  A biasing member biases the latch carriers toward the longitudinal axis.  The locking latch has a first portion which, in the "on" position of the switching slide, engages the detent recess in the free end of the detent bolt to retain the detent bolt within the door lock housing, and has a second portion which, in the "off" position of the switching slide, engages the stub end of the switching slide to retain the switching slide against longitudinal movement toward the "on" position.

IPC: H01S5/183
Filed: 1991-02-25
Granted: 1994-02-08
Abstract: Abstract Top surface emitting, vertical cavity, surface emitting lasers depend upon emission through apertured top surface electrodes. Biasing current, accordingly peripheral to the laser as introduced, follows a path which comes toconfluence within the active gain region to effectively attain lasing threshold. The path is a consequence of a buried region of increased resistance which encircles the laser at or above the active region. The buried region is produced by ion implantation-induced damage with ion energy magnitude and spectrum chosen to produce an appropriate resistance gradient. Integrated, as well as discrete, lasers are contemplated.

Title: Two-stage mat forming and preforming
Inventor: BUCKLEY DANIEL T
IPC: C03B37/00
Filed: 1992-12-17
Granted: 2002-09-17
Abstract: Glass fiber mats are made for subsequent use in preforming for an RTM or SRIM molding process, for example, such that the binder applied to the mat has two distinct curing stages. In the first stage, a partial cure is provided by visible light upon a free radical generation in response to a photoinitiator mixed in the binder in an exact ratio to give a predictable increase in viscosity to that of a semi-solid so that the fibers are sufficiently bound for subsequent handling, but not sufficient to complete a cure, while leaving a second stage ready for a final cure which is achieved by the use of a cationic-type second photoinitiator which is sensitive to ultraviolet light. During the second curing stage, the mat is formed into a three-dimensional shape of a desired end product and cured with ultraviolet radiation while still in the mold, to obtain a rigid three-dimensional preform structure. 2.8 2.5
