Patent CA-2037940-A1 (CA)
Inventor: GOLDBERG JACK
IPC: G01J5/00
Filed: 1991-03-11
Abstract: An infrared detector receives infrared energy from the target and provides a detector signal based primarily on the difference between the infrared detector temperature and the temperature of the reference temperature area of the detector. A contact temperature measurement device provides a reference signal which is a function of the temperature of the reference temperature area of the detector. A processor receives the detector and reference signals and combines the two signals in a non-linear manner to result in a signal which is representative of the temperature of the target. The method of non-linearly combining includes the use of gain and offset terms which may be altered to a limited extent by a technician in the field with a blackbody calibration source. As a result of the recalibration, accurate target temperature measurements are continually provided. Additionally, the method of non-linearly combining includes the use of additional gain and offset terms which are adjusted to account for the infrared radiation characteristics of an anatomical target as compared to blackbody calibration source targets.

Title: Telecommunications network with plesiochronous transfer mode
Inventor: GOLDSTEIN FRED R
IPC: H04L12/56
Filed: 1991-04-12
Abstract: TELECOMMUNICATIONS NETWORK WITH                 PLESIOCHRONOUS TRANSFER MODE     ABSTRACT OF THE DISCLOSURE   A telecommunications network of the type having links with long propagation delay uses an asynchronous transfer mode in which small, fixed-length blocks of information (cells) are transferred at very high speed. Each long-haul hop within the network is phase-locked to a fixed period, and time slots of a granularity of one cell are pre-allocated to the virtual circuits. The network operates in a near-synchronous (plesiochronous) manner. By pre-allocating cells, it is assured that the cells will not arrive at a faster rate than that at which each receiving node can forward them on to the next hop. When bursts of heavy traffic occur, the network responds by slowing or limiting access, rather than by loss of data at intermediate nodes due to bufferoverflow.

Title: Method for cleaning the walls of heat exchangers, and heat exchanger with means for said cleaning
Inventor: KLAREN DICK GERRIT
IPC: F28G1/12
Filed: 1991-04-15
Abstract: ABSTRACT           For cleaning at least one of the sides of the essentially vertical heat-transmitting walls between two fluids in a heat exchanger, solid particles are introduced into a stream of fluid, which particles are smaller than the distance between opposite walls defining the flow of fluid, said fluid with particles being introduced into part of a collection or distribution space above said walls and said particles being collected below said vertical walls and discharged from the heat exchanger.  The particles are so heavy that they move downwards in the fluid even if this has an upward direction of flow between the walls.  The particles are introduced above only part of the transverse plane above the vertical walls and switch means allow switching of said introduction to other parts of said transverse plane periodically.       Thereby, the normal operation of the heat exchanger can continue with hardly any pressure loss during cleaning.

Patent CA-2051936-A1 (CA)
IPC: E04H4/16
Filed: 1991-09-20
Abstract: A suction head for a swimming pool cleaner comprising a housing which is open at its lower side and has inclined bristles attached to its lower edge for supporting on a surface to be cleaned. The housing has a rotary sleeve mounted to its top for connection of a suction hose in turn to be connected to a water suction pump. Said sleeve opens in a chamber within the housing in which a vibratory element is pivotally mounted, said element having a crescent or air-foil shape. By a flow of water sucked through said chamber, the vibratory element is automatically brought into a vibrating movement which imparts pulsations on the suction head. Thereby, the inclined bristles are bent and straightened repetitively, resulting in a forward thrust moving the suction head over the surface to be cleaned. At least one foot is disposed in the housing which is cyclically displaced vertically by a driving mechanism driven by the movement of the vibratory element and returned by return springs. Said foot cyclically lifts off the suction head at one side, resulting in a rotational movement of the suction head about a vertical axis so as to change the direction of forward movement of the suction head.

Filed: 1992-01-14
Abstract: REFRIGERATION TEMPERATURE CONTROL SYSTEM               ABSTRACT OF THE DISCLOSURE    Apparatus for and method of long-term control of the temperature within a refrigerated space,  such as the cargo compartment of a refrigeration truck.   The technique employs sensors which monitor both discharge and return air.  A control algorithm uses the multiple sensors  to  control  modes  of a  refrigeration  unit capable of supplying cooled or heated air.  This causes the temperature within the refrigerated space to remain within a narrow range about a target temperature.  The target is chosen to provide maximum safety for the cargo.   If the target temperature is too high,  the cargo is needlessly exposed to spoilage.  If the target temperature is too low,  the cargo is subject to the risk of damage from freezing.
