Patent CA-1116190-A (CA)
Inventor: SMITH LAWTHER O
IPC: F16F9/49

Granted: 1982-01-12
Abstract: ABSTRACT     A gas spring comprises an annular oil cushion seal near the main seal end of the cylinder which defines an oil cushion chamber with the main seal.  A flow-restricting passage through the oil cushion seal permits controlled flow of gas and oil from the rod chamber to the oil cushion chamber to provide a second phase of damping as the rod nears the fully extended position and bypass communication from the tube chamber to the rod chamber is via the damping passage in the oil cushion seal and the main damping passage which bypasses the piston, which passages are in series at the end of the operating stroke.  The second stage of damping essentially eliminates oscillation of the gas spring at the end of the operating stroke.

Abstract: ABSTRACT             New fluorinated benzenesulfonate diacetylene com-positions are described which are useful in time-temperature devices for monitoring the shelf-lives of perishable arti-cles.  The compositions are solid-state polymerizable by thermal annealing or exposure to actinic or high energy ionizing radiation.  Some of the compositions, in addition, exhibit relatively longer polymerization induction periods, compared to other known diacetylene compositions, and an "autocatalytic" effect upon polymerization during which a rapid color change occurs. These characteristics are extremely useful in monitoring situation which require a striking color change as an indication that a particular time-temperature history profile, e.g. shelf-life, has expired.

Abstract: ABSTRACT    A Scan Converter for use with an Ultrasonic Imaging System is disclosed, which permits the buffering of sweep address and video data with five bits of information.  In essence, the propogation path of the Ultrasonic pulses is resolved into a pair vectoral components while the propogation path media is defined by successive contiguous body segments which are to be respectively displayed as video picture elements.  A series of first signals indicate the crossing of segment boundaries in the vectoral direction having the faster rate of boundary crossings.  A second signal is produced having a unique value which indicates a boundary crossing by the pulse in the other vectoral direction.  Reflections of the Ultrasonic pulse are sampled at a rate determined by the first signals; i.e., the rate at which segment boundaries are crossed in the first vectoral direction.  The sample values are held for storage in memory.  The memory includes a matrix of memory location associated with respective picture elements.  The one coordinate of the memory address is successively incremented with the storage of the held values.  The second coordinate  of the address is incremented by the unique value of the forementioned second signal; in other words, when a segment boundary is crossed in the slower vectoral direction.

Abstract: Gamma camera ABSTRACT:         The peripheral part of the optical block of a gam-ma camera, which is formed by the scintillation crystal and the optical conductor, is provided with a diffusive light reflector, the reflection and optical diffusion properties of which are combined in relation to the wavelength of the scintillation light so that signal/distance curves for each of the photomultipliers used are substantially coin-cident within the useful field of the camera. This improve-ment results in a suitable compromise between on the one hand linearity and spatial uniformity and on the other hand spatial and energetic resolution of the gamma camera.
