Patent CA-2060942-A1 (CA)
Inventor: GOENNER SIEGMAR
IPC: B27L5/06
Filed: 1992-01-29
Abstract: In an apparatus for cutting severing of a thin board (22) from squared timber (6) which is moved on a guide surface (4) against the cutting edge (16) of a blade (14) the adjustment of the distance between the guide surface (4) and the plane (24) parallel thereto extending through the blade cutting edge (16), and thus the adjustment of the apparatus to different board thicknesses to be produced, is effected by relative adjustment of the blade cutting edge (16) to the guide surface (4) in an inclined plane (36) which forms an acute adjustment angle (.alpha.) to a normal (32) to the guide surface.            With this arrangement, with a changed board thickness adjustment of the apparatus the distance between the blade cutting edge (16) and a counter pressing edge (30) in the cutting direction is automatically adapted. Furthermore, in a preferred embodiment with this adjustment the width of the exit guide channel (between the surfaces 26 and 50) for the separated board (22) can be simultaneously set to the new thickness.

Title: Two-cycle peristaltic pump with occlusion detector
Inventor: HYMAN OSCAR E
IPC: A61M5/168
Filed: 1992-02-27
Abstract: A linear peristaltic pump for pumping fluid through a resilient tube has a pair of pumping fingers,  a pair of pinching fingers,  and a strain gauge to monitor pressure inside the tube.  The first pumping finger squeezes the tube at a first location, and the second pumping finger squeezes the tube at a second location.   Additionally,  the first pumping  finger  is  configured  and  operated  to  displace approximately twice the fluid volume displaced by the second pumping finger.  The first pinching finger occludes the tube upstream to the first pumping finger and the second pinching finger occludes the tube between the first and second pumping fingers.  To monitor dimensional changes in the outer diameter of the tube and thereby indicate pressure inside the tube, the strain gauge  is mounted on the pump between the second pinching finger and first pumping fingers.  Finally, a leaf spring and photoelectric sensor are associated with the first pumping finger to indicate when the finger is in its fully withdrawn position.

Title: Windings for electromagnetic machines
Inventor: GAVRILIDIS GEORGE
IPC: H01F41/04
Filed: 1992-03-16
Abstract: Coils, for installation in slots in laminated cores of electromagnetic machines, particularly linear induction motors, are insulated by wrapping successively with heat resistant  tape,  tape  of  a  curable  silicone  rubber composition which may  be  glass  fibre  reinforced,  and further heat resistant tape, and curing the rubber whilst pressing to size those portions of the coil to be inserted in the slots.  The heat resistant tapes form a mould within which the rubber is cured to form an insulating jacket. The inner layer of tape includes a lubricant layer of PTFE tape.  Connections between adjacent coils may be similarly insulated  when  the  coils  are  assembled  prior  to installation in a core.

Title: Raman laser
Inventor: WHITTLEY STEWART T
IPC: H01S3/22
Filed: 1992-07-17
Abstract: ABSTRACT                        Raman Laser The  present invention provides a Raman laser  wherein hazardous  radiation from a pump laser source 20 is  focused by lens  25  via a cell 27 containing a Raman active  medium before  passing to a absorbing beam dump 30.  Lasing  action is maintained within the cell 27 by the action of mirrors 29 and 26   which  are  respectively   totally  and   partially reflective  to radiation generated at the Raman  wavelength, and which  are both transmissive to the pump beam.  A  Raman beam exits  the cell via partially transmissive mirror 26 is refocused by lens 25 and passes through to the output of the device  31.  This configuration provides a Raman laser where the "eyesafe"  Raman  beam  is   generated  in  a  backwards direction  relative to the pump beam, so that during  normal operation,  or  in the event that the optics  breakdown,  or conversion  does not take place within the cell, the  output beam would  not  be  contaminated   by  potentially  harmful wavelengths at a hazardous level.

Abstract: The present invention relates to a novel process for forming porous metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Such spontaneous infiltration occurs without the requirement for the application of pressure or vacuum.  However, the amount of matrix metal provided is insufficient to embed substantially completely the filler material or preform.

Filed: 1991-06-21
Abstract: The present invention relates to a biomimetic sensor for detecting the presence of airborne toxins, such as carbon monoxide, mercury, ethylene oxide, volatile organic materials, and hydrogen sulfide. The biomimetic sensor, which has a functional life of at least one year, comprises a porous, semi-transparent substrate into which is impregnated a self-regenerating chemical sensor reagent.

Title: Radio frequency volume resonator for nuclear magnetic resonance
Inventor: MURPHY-BOESCH JOSEPH
IPC: G01R33/34
Filed: 1991-10-10
Abstract: An RF resonator for use in NMR is mounted on a dielectric support sufficiently large to permit insertion of a patient's head. The resonator consists of four axially distributed high frequency ring current paths (56, 58, 59, 60) on the support (40) and at least four high frequency current paths (50) interconnect each pair of adjacent ring paths. In the preferred embodiment at least sixteen equally spaced parallel segments (50) connect each ring pair and are aligned with one another. The ring segments between the parallel segments together with the parallel segments form loops. At least one discrete capacitor (62, 64) is placed in each outer current loop thereby interrupting the loop. However, this is done so that no inner loop is interrupted by a capacitor. Therefor, each inner loop has effectively no capacitance and is now resonant at radio frequencies.

Abstract: NUBUS DUAL DISPLAY CARD             ABSTRACT A dual display generator card (10) that is insertable into a Nubus card slot of a computer system (12) that permits the simultaneous generation of images for two display monitors (13, 14). The dual display generator card (10) includes a Nubuscomputer interface (21) and two display channels (30a, 30b). Each display channel (30a, 30b) includes a channel memory buffer (31, 32), two parallel video translators (33), and a digital to analog converter (36). Video output signals from the each display channel (30a, 30b) are provided from the digital to analog converter (36) and are cou-pled to each respective video display monitor (13, 14). Appropriate timing, address, and control hardware are provided to control the generation of video signals. Overlay information derived from the computer system (12) may be overwritten on pixel data to support annotation of images rendered on the display monitors (13, 14). The result is a composite image provided on the two monitors (30a, 30b). Each of the two images is a combination of pixel image data from the display card (10) and the overlay data gener-ated by the computer system (12). The CPU of the computer system is not required to manipulate the image pixels. Consequently, the CPU only has to process the overlay information, a small part of the overall information content displayed on the display monitors (13, 14), and hence the speed of image generation is improved.
