Title: Imaging diode array and system
Inventor: SMITH RONALD S
IPC: G06K15/12
Filed: 1990-12-14
Abstract: Abstract of the Disclosure An LED exposure array and system for printers, and methods of inputting data to and operating the array, are disclosed.  The array can be loaded and refreshed with data information at rates compatible with high speed printing, and includes an LED configuration which can emit high energy in a controlled pattern to give a desired pixel spot on a photoreceptor.  The array incorporates a system for compensating for differences in illuminating capability of a large array of LEDs, by introducing modifications in LED on-time which are centered with respect to the incremental area of the photoreceptor on which a pixel is to be formed, and to compensate for changes in pixel exposure time with increase in speed of the photoreceptor.  A unique mounting of the array maintains each light emitting spot in focus on the photoreceptor surface, although a wide array is employed.  There is also disclosed an electronic image forming and handling system which can load and refresh the exposure array at variable speeds of at least 100 to 300 ft./min.
Patent CA-2034099-A1 (CA)
Title: Water heater
Inventor: JENSON MAURICE
IPC: F23N5/20
Filed: 1991-01-14
Abstract: ABSTRACT   A water heater includes a tank for receiving cold water and dispensing heated water. A thermostat is associated with the tank and detects the temperature of water held therein. A gas burner including a hot surface igniter receives fuel to be combusted via a fuel line when a valve on the fuel line is opened. A controller is responsive to the thermostat and opens the valve and operates the igniter to ignite the fuel when the temperature of the water held in the tank falls below a first predetermined level. A vent including a flue passes through the tank and allows combustion gases and heat of combustion to be vented from the water heater. The vent includes a blower responsive to the controller which mixes ambient air with combustion gases prior to venting the combustion gases to the atmosphere. The controller initiates the blower when the water temperature falls below the first predetermined level to establish at least a predetermined pressure in the flue before the valve and igniter are operated. When the water temperature rises to a second predetermined level, the controller shuts off the igniter and the valve and maintains the blower in operation for a preset time to exhaust substantially all combustion gases and heat of combustion from the water heater.

Patent CA-2040234-A1 (CA)
Inventor: MESSENGER STEVEN
IPC: H04L12/28
Filed: 1991-04-11
Abstract: Spaced-apart communication controllers connected to a cable-based network place a portable device in communication with the network for transfer of data packets. Each controller communicates with the portable device with packet transmissions through air, and requires registration of the portable device before offering packet transferring services. The registration process involves transmitting a packet from the portable unit requesting a response from controllers, transmitting a response packet from each controller receiving the request, selecting one of the responding controllers at the portable unit according to criteria that enhance data transfer, and transmitting from the portable unit a packet identifying the selected controller to complete registration. The selected controller transmits to other controllers via the network cable a packet confirming the registration. A controller with which the portable device was previously registered responds by de-registering the device and transmitting any stored packets addressed to the device via the cable to the newly selected controller. A power saving protocol is implemented for a battery-operated portable device and adjusted continually to accommodate the rate at which transmissions to the device occur. The power saving arrangement includes disabling the receiving section of the device.

Inventor: MUNDT WOLFGANG
IPC: A61K35/76
Filed: 1990-12-21
Abstract: A matrix or substrate bears adherently bound human or animal cells infected with a virus. It has been shown that surface dependent cells useful for virus multiplication remain adherently bound to a matrix even when infected with a virus, produce virus antigens over a relatively long period of time and release them in the culture medium. In order to produce early Summer meningo-encephalitis (FSME) virus antigens by cultivating the FSME virus in cell cultures, a surface dependent permanent cell line, preferably the vero-cell line ATTC CCL 81, is inoculated with the FSME virus and the cells are bound to substrates and kept in a non lytic serum free system in conditions that ensure cellular growth, so that antigens are produced. The antigen-containing medium is then separated from the substrate bound cells and processed in a known manner by concentration, inactivation and purification until a galenically acceptable composition is obtained.
