Title: Gastro-jejunal feeding device
Inventor: PARKS STEPHEN K
IPC: A61M25/02
Filed: 1987-05-08
Granted: 1991-02-05
Abstract: ABSTRACT             GASTRO-JEJUNAL FEEDING DEVICE     A device is disclosed for supplying food and medication to a patient,  the device being inserted through a stoma and into the patient's stomach for feeding  into the stomach and/or  the  jejunum.   The device may also be used  to feed directly into the jejunum by by-passing the stomach,  or for drainage and/or decompression.        The device is secured in place by an inflatable balloon (32) within the stomach, or by a plate if the stomach is by-passed, and by an adjustable ring (43) on the abdominal wall.  The adjustable ring also prevents ingestion of the device into the stomach.  During use, the ring can be retracted to permit cleaning of the stoma area.  The ring can be perforated (42) and ribbed (41) to provide improved ventilation of the stoma area during use.     The device can be employed with conventional surgically  formed  procedures,  and  is  replaceable. Servicing of the device can be made at home, rather than at a hospital.

Abstract: CONTROL AND DISPLAY SYSTEM               ABSTRACT OF THE DISCLOSURE     A control system comprises a liquid crystal display panel; a light source; light detector means; and means fox directing light through at least a portion of the liquid crystal display panel to the light detector means.  Control means are provided for holding the liquid crystal display in generally opaque condition while preferably sequentially momentarily clarifying segments of the portion, whereby momentary, sequential, transversely spaced light beams are generated between the light source and the light detector means. Timer and logic means are provided for correlating signals received from the light detector means with generated, individual, spaced light beams that create said signals.  Accordingly, occlusion of at least one of the individual light beams with an opaque member causes a specific characteristic response by the timer and logic means.  In other words, when one of the individual light beams is occluded, the timer and logic means emits a characteristic signal which might activate a relay, send an instruction to a microprocessor, or cause some other action.

Title: Peak detector and imaging system
Inventor: BLAIS FRANCOIS
IPC: H03K5/1532
Filed: 1988-09-13
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE   A circuit for detecting the positions and intensities of peaks in a digital input signal (which may be a digitized version of a signal from a CCD forming part of a three dimensional imaging device) employs a second derivative of the input signal for validating the presence of each input peak.  Each validation signal enables an interpolation circuit that determines the position of a peak by finding the location of a zero crossing point of a first derivative of the input signal.  Each validation signal also enables a maximum detector for measuring the intensity of each peak.  The arrangement does not require resetting after each detection of a peak and is less sensitive than prior devices to noise or DC or low frequency components.

Patent CA-1304809-C (CA)
Inventor: CARMES FRANCIS
IPC: B61L5/10
Filed: 1988-11-22
Granted: 1992-07-07
Abstract: The device comprises a geared motor (17) which drives longitudinally, via a ball screw (20) and nut, the central body (22) of a moving element comprising two slides (24, 25) sandwiching the central body (22). The two slides mesh on a common pinion mounted so as to rotate freely in the central body (22). Each slide drives, via a vertical, cylindrical floating pin (34, 35, 38, 39), a control bar (9, 10) linked to a throw rod (7, 8) which is itself linked to a switch blade. The locking of an operating bar (9, 10) is effected at the end of the travel of the central body (22) by the positioning of a floating pin in a locking groove (40 to 43) of a fixed locking plate (30, 31). A mechanical fault in the transmission chain causes a relative displacement of the slides (24, 25) with respect to the central body (22), which displacement is detected by the rotation of the common pinion integrally connected to means (27) for actuating an anomaly-control contact (29).

Abstract: ABSTRACT     The printing machine is composed of two essentially identically constructed halves which each have an impression cylinder        , an image transfer cylinder resting against this, a blanket cylinder and a collect-printing plate cylinder        .  In the offset-printing position, the blanket cylinder rests against the impression cylinder         and is inked by offset plate cylinders, whilst the collect-printing plate cylinder is inoperative.  In the collect-printing position, the blanket cylinder is moved away from the impression cylinder        , is inked by color selector cylinders         and itself inks the collect-printing plate cylinder  which rests against the image transfer cylinder Moreover, in both printing positions, the image transfer cylinder is inked by the plate cylinder of an additional single-color printing unit.  The paper first loops partially round the impression cylinder     of the first machine half and is thereby printed directly on one side by the image transfer cylinder and, in the offset-printing position, also by the blanket cylinder and than loops partially round the impression cylinder     of the second machine half, the other side of the paper being printed in a similar way.
