Title: Toner developed electrostatic imaging process for outdoor signs
Inventor: CHOU HSIN-HSIN
IPC: G03G13/00
Filed: 1990-12-17
Abstract: An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.

Inventor: NICOL JOHN J
IPC: G08B29/06
Filed: 1991-04-18
Abstract: An interface for a supervised multiple input, audible warning system is disclosed. The interface continuously monitors or supervises a plurality of circuits between a control unit and an alarm unit for electrical faults. Each circuit represents a separate alarming condition. All the circuits are coupled to but normally isolated from each other and a common circuit for driving a piezoelectric device. The isolation is accomplished by means of a semiconductor switch normally reverse biased.          The semiconductor switch prevents the supervising current of one circuit from driving the piezo by isolating all possible flow paths to all circuits without current flow in the alarming direction. Upon sensing an alarming condition, the direction of the current in the alarming circuit reverses resulting in forward biasing the semiconductor switch. The current in the alarming circuit, no longer isolated from the common circuit, actuates the common circuitry necessary for generating the audible warning . The interface circuits may be connected to an addressable micro controller for selecting a multitude of sounds.

IPC: G02B6/44
Filed: 1991-07-04
Abstract: A fiber-optic connection system comprises three interfitting plastic parts.  A two-piece cable terminal includes a cable receiving body and a terminal body.  The terminal body has two spaced projections which mount the fiber ends and has a pair of converging cable guide walls.  The cable receiving body has walls with gripper teeth complementary to the guide walls. When two cable strands are introduced and the bodies are interconnected to form the terminal connector, the walls trap the cables.  The fiber ends are finished by hot plate melting.  The terminal connector is inserted into a header having pockets to mount electro-optical devices.  The pockets have integral spring rails to force the devices into contact with the projections containing the fiber ends upon assembly.  A series of integral lock tangs and shoulders retain the component parts interconnected to prevent inadvertent disassembly.

Abstract: EYE DIRECTED CONTROLLER            ABSTRACT     A method and apparatus  for operating a video game, controlling the cursor position on a computer display, and controlling the operation of equipment and devices using electro-oculogram and electro-myogram signals resulting from eye movement and muscle contractions  in the human body. Operator (10) wears sensor assembly (12) which is connected to control  processor  (18).   Movement  of the  eyes produces electro-oculogram signals which control processor (18) detects and converts into separate control signals representing upward movement, downward movement, movement to the left and movement to the right.   Muscle contractions produce electro-myogram signals which control processor (18) detects and converts into control signals.   The control signals are interfaced with equipment (22) which is a computer or video game having a display  (24),  or other apparatus to be controlled.   The electro-oculogram control signals are used to control cursor position on a video game or a computer, while the electro-myogram signals are used to simulate the operation of a switch or "fire control" button.   The functions of a "joystick", "mouse", "track ball" and the like are thereby replicated by the method and apparatus disclosed herein.
Patent CA-2050033-A1 (CA)
Title: Knife switch
Inventor: GABRIEL CLAUDE D
IPC: H01H9/22
Filed: 1991-08-27
Abstract: ABSTRACT       A bar providing switch means is pivotally connected to a terminal supported within an insulating housing.  In normal operating position the knife switch is closed to two switch contacts which allow connection of power from one of the contacts to two types of circuits, such as propulsion and the auxiliary circuits of a railway car.  The insulating housing may be provided with a cover which is closed when the switch is in normal closed circuit operating position.  To change the position of the switch, the cover must be opened.  The bar may be pivoted somewhat less than 180° to engage a single contact which connects the power to one of the circuits, but not the other, for example, only to the auxiliary circuit of a railway car.  The knife switch is prevented from moving 180° by an end wall of the housing.  But in that position it closes to one contact so that it may be viewed as being closed to power the auxiliary circuit.  When in other positions, the switch is also viewed as in non-operating open position.  However, the bar is provided with a bug stud extending transverse to the direction of movement of the knife switch in operation.  The bug stud may be engaged by a shop power connector enabling the auxiliary circuit to be energized without using the normal power source. The connector interferes with the edge of the box so that the knife switch is not capable of being closed in either direction when the shop power connector is engaged.

Title: Ore feed heating
Inventor: SMITH C NEIL
IPC: C22B1/00
Filed: 1991-10-30
Abstract: An improved method of extracting minerals from ore is described. The method is applicable to vat leaching operations and may also be useful in heap leaching operations. The method involves the pre-heating of comminuted ore prior to the agglomeration phase. The method is found to improve the quality of the agglomerate and to reduce the curing cycle time. In addition, the method described herein induces extra heat into the agglomerated mass which, as well as enhancing the agglomerate quality, adds heat to the leach solution resulting in higher mineral recoveries. The method is especially useful in the winter months when ore temperatures are low; however, improved results are realized when the method is used in the summer months as well.
