Inventor: SCHMIDT RONALD J
IPC: G03C1/06
Filed: 1991-04-29
Abstract: A high-contrast room-light-handleable black-and-white photographic element is comprised of a support having on one side thereof a silver halide emulsion layer and having, on the same side of the support as the silver halide emulsion layer, both a filter dye layer in which the dye is immobile and a matte layer comprised of a matting agent dispersed in a hydrophilic colloid that serves as a binder. In this element, the filter dye layer serves to provide uniform filtering of incident light, while the matte lay-er provides a rough surface which facilitates rapid vacuum draw-down during contact exposure.

Title: Internal combustion engine
Inventor: MERRITT DAN
IPC: F02B3/06
Filed: 1992-10-28
Abstract: An internal combustion engine has at least one set of first and second cylinders (12,14), the first cylinder (12) having a larger swept volume than the second cylinder (14), and respective first and second pistons (16,18) movable in the cylinders. The pistons are coupled together such that they are movable in the cylinders in a cyclic manner at the same frequency. An air inlet (24) and an exhaust outlet open into the first cylinder and a fuel injector (34) provides fuel to the second cylinder. A combustion space (20) is also provided which communicates with both cylinders during at least a portion of the expansion stroke. The second piston has a crown (35) and a body portion (19), with the crown being spaced from and connected to the body portion and having an edge (37) which is relatively small in the axial direction compared to the distance between the crown and the body portion in the axial direction. The combustion space (20) is defined between the piston crown and body portion and a side wall (14a) of the second cylinder. The gap (128) between the crown edge (37) and the cylinder wall (14a) serves to inhibit ingression of fuel into the combustion space (20) until towards the end of the compression stroke. Access means (30) associated with the second cylinder for admitting fuel and/or air to the second cylinder during the induction stroke comprises a port (33) opening into the second cylinder and a valve (31) for controlling port. <IMAGE>
Patent CA-2081671-A1 (CA)
Inventor: UCHA CLAVO ELOY
IPC: A61B19/00
Filed: 1991-02-28
Abstract: 2081671 9215256 PCTABS00016 The present invention relates to a method and apparatus for locating anatomical cavities such as the epidural space. The puncture will be made on the basis of the loss of resistance technique with a seringe (12). The tapping is facilitated by taking some measurements in the operation region (15) and by the emission of acoustic and visual warning signals, as well as by the provision of data displayed on a screen (16), all of which quantify and corroborate the tactile feelings of the operator, influencing the operator's work and allowing the operator to make proximal trials which are not harmful or damaging, and to be extremely sure that the cavity has been reached. The method is applicable independently of the pressure characteristics of the space to be detected, and uses a conventional needle, which also makes an apprenticeship possible in optimal safety conditions.

Title: Automatic sensitivity control in an implantable cardiac rhythm management system
Inventor: KELLY DAVID W
IPC: A61N1/36
Filed: 1993-07-30
Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for automatically adjusting the sensing    threshold    in    an    automatic    implantable cardioverter/defibrillator  with  pacing  capability.     Fixed sensitivity is used for a specified interval following each pacing pulse and automatic sensitivity adjustment is used whem spontaneous cardiac depolarization  is detected.   For spontaneous  cardiac depolarization, the sensing threshold is automatically adjusted to a value proportional to the amplitude of the sensed cardiac signal.          The sensing threshold continuously decreases between sensed cardiac depolarizations, ensuring that a lower level cardiac signal will be detected.  When a pacing pulse is delivered, the sensing threshold is set to a fixed value and held at that value for a predetermined period of time such that the sensing threshold will not be affected by the cardiac response evoked by the pacing pulse.  At the end of the  predetermined  period  of  time,  the  sensing  threshold  is decreased  as   it  would   following  a  spontaneous  cardiac depolarization.

Title: Method and apparatus for determining substances and/or the properties thereof
Inventor: GLAUS ULRICH W
IPC: G01J3/36
Filed: 1993-11-29
Abstract: ABSTRACT            The invention concerns a procedure that is principally shown in figure 2. A sample of material, which material or its properties having to be determined, reflects or transmits the electromagnetic radiation of a radiation source (1). The radiation from the sample is collected and analysed over several channels (7,7',7''), which modulate the radiation with a spectral transmission function prescribed individually for each channel. The modulated radiation is transmitted to one or several detectors (9,9',9''), whose output signals are further electronically processed. The spectral range for which the channels are sensitive, is the same for all channels. But within that common range the channels have different spectral transmission functions (7,7',7''), which are optimally adapted for a given application.                       (fig. 2)
