Filed: 1991-09-24
Abstract: Abstract of the Disclosure A belt press has horizontally extending and vertically spaced upper and lower plates defining a horizontally extending gap, vertically spaced upper and lower upstream drums rotatable about respective horizontal drum rotation axes at the upstream press end, and vertically spaced upper and lower downstream drums rotatable about respective horizontal drum rotation axes at the downstream press end.  Each of the downstream drums is supported for at least limited pivoting about a vertical axis generally intersecting the respective drum rotation axis.  Upper and lower endless belts spanned over the respective upper and lower drums each have a working stretch lying between the plates and a return stretch.  Upper and lower pairs of horizontally spaced outer adjustment rollers rotatable about respective horizontal axes fixed each engage the respective working stretch in a predeter-mined vertical direction and respective upper and lower central adjustment rollers positioned between the respective outer rollers engage the respective working stretch in a vertical direction opposite to the respective outer rollers.  Each central adjustment roller can pivot about a horizontal axis generally centrally passing perpendicularly through the respective central adjustment roller.  Sensors detect the position of the belt transversely of the direction and a controller pivots the drums and central adjustment rollers about the respective adjustment axes in response to the respective detected belt position.

Abstract: ABSTRACT:      A  dripping set with an automatic closing ball  float, in  which  a  hollow  ball float  is  installed  in  a  fluid reservoir;  as  soon  as a fluid in the  fluid  reservoir  is drained away, the ball float will be lowered to an outlet  at the bottom of the fluid reservoir automatically to close  the outlet  as  a result of the attractive force  of  the  fluid; then, a given amount of fluid will be left in a fluid hose to prevent a blood from flowing into the fluid hose, and such  a feature can facilitate refilling fluid for the next injection operation.
Patent CA-2053596-A1 (CA)
IPC: G02B6/44
Filed: 1991-10-16
Abstract: An optical fiber cable (20) ideally suited for aerial distribution use, for example, includes in a preferred embodiment at least one bundle (23) of optical fibers (25-25). The at least one bundle is disposed in a tubular member (30) which is made of a plastic material suitable for use in a relatively wide temperature range and which is enclosed by a sheath system (32). A predetermined excess length of fiber is caused to be disposed in the tubular member. The excess length of each fiber is such that it is sufficient to avoid undue strains on the fiber as the cable core is exposed to the elements and to forces imparted during handling such as during installation. On the other hand, the excess fiber length must not be so great as to result in undue curvature of the fiber or excessive interactive engagement of the fiber with an inner wall of the tubular member. As a result of the magnitude of the excess length of the opical fiber, the requirements which must be met by the sheath system are not as demanding as for prior art cables, thereby resulting in a significant reduction in cable diameter and weight.

IPC: A63B69/06
Filed: 1991-11-22
Abstract: A rowing exercise apparatus is capable of emulating the actual sensations of rowing, including the sensation of tippiness at slow rowing speeds and also providing an artificially induced sense of motion to the rower of the apparatus at the end of each rowing stroke.  The energy put forth by the rower by pulling the oars is transmitted to the gyroscopic flywheel by a system of belt and pulleys operatively connected between the oars and the flywheel for the purpose of creating and maintaining stability of the rower's seat, which then simulate the action or feeling of a rower in a shell gliding in water.  The rowing exercise apparatus is capable of lending itself to group participating exercise by means of coupling two or more machines, end to end, in a horizontal plane.

Title: Insertion and tunneling tool for a subcutaneous wire patch electrode
Inventor: DAHL ROGER W
IPC: A61N1/05
Filed: 1992-06-04
Abstract: A tool (1) for subcutaneously implanting a subcutaneous electrode comprising several wire patch electrode segments by way of a single surgical incision. The tunneling tool (1) comprises a stylet (2) and a peel-away sheath (8). The tunneling tool (1) is inserted into an incision, in a direction which corresponds to the desired placement of an electrode segment. Once the tunneling tool reaches a desired position, the stylet (2) is withdrawn, thereby revealing the interior of the peel-away sheath (8) and a resulting subcutaneous tunnel. The corresponding electrode segment is then inserted into this subcutaneous tunnel, and subsequently implanted in the patient. The implantation procedure is then repeated as many times as is necessary, using the same incision, until all the electrode segments for the particular electrode configuration have been implanted. In addition, the tunneling tool (1) can be adapted to conform to varying electrode segment sizes, which thereby allows the tool to conform to the varying needs of each individual patient. As an even further feature, the tunneling tool (1) can be constructed in a curved configuration to facilitate electrode implantation in the lateral thoracic region of the body. <IMAGE>

Title: Simple compact ion mobility spectrometer
Inventor: THEKKADATH GOVINDANUNNY
IPC: G01N27/64
Filed: 1992-08-20
Abstract: A compact ion mobility spectrometer (IMS) with increased sensitivity and resolution for detecting the composition of an unknown substance is disclosed. The IMS comprises a unitary cylindrical housing, inlet means for introducing sample gas, outlet means for withdrawing sample and drift gas, two high voltage electrodes, and a detector. The first electrode is pulsed to inject sample ions through an opening located in a second electrode which defines a drift region. The second electrode is cup-shaped having an open end and is electrically biased to create a non-uniform electric field gradient across said drift region. The electric field in said drift region is axial and radial resulting in an increase in ion drift velocity at the detector and a corresponding increase in detected peak signal amplitudes thereby increasing resolution. A shorter drift region and the absence of an aperture grid near the detector which cause ion collisional losses, helps to increase IMS sensitivity.
