Patent CA-2148580-A1 (CA)
Inventor: CHEN CHUNGTE W
IPC: G02B27/00
Filed: 1994-09-29
Abstract: An optical display system in which an image is projected onto a combiner surface (4) at a significant bending angle .theta. effectively compensates asymmetric aberrations, including quadratic, linear and constant binodal astigmatism components and both linear and constant coma components. Forward and rear optical lens relay groups (14, 16) are positioned between an image generator (6, 8) and the combiner surface. The two relay groups are independently decentered and angularly tilted to increase the degrees of freedom available for aberration compensation. The lenses (24, 26, 28, 30, 32, 34, 36, 38, 40) included in the two relay groups are also designed to compensate for chromatic aberrations, thus allowing for the use of a broad bandwidth combiner and an operating bandwidth that encompasses substantially the full visible spectrum. The reduction in aberrations makes possible a significant increase in the system's field of view.

Patent CA-2155132-A1 (CA)
Title: Process and apparatus for thickening of solid liquid mixtures by means of membrane technology
Inventor: HARTMANN EDUARD
IPC: B01D61/14
Filed: 1994-11-17
Abstract: To thicken retentate residues using ultra- or microfiltration to clarify fruit juices, apparatuses which have membrane modules (1, 2) are used in the cross-flow process with a retentate circuit. It is proposed that first, the process be carried out with virtually constant retentate overflow velocity at the membranes until there is an increased concentration. Then the transmembrane pressure of membrane modules (1, 2) is kept constant or further increased, and the overflow velocity is reduced, until the desired thickening of the retentate residue is achieved. So that the last reduction step can be carried out, speed-governed retentate displacement pumps (8) are employed. To prevent stoppages of the membranes of membrane modules (1, 2), the apparatus is operated with special flow dividers (10) for the retentate, or an individual circulating pump is associated with each group of membrane modules.

Title: Mechanical pencil
Inventor: SHUHEI KAGEYAMA
IPC: B43K21/16
Filed: 1995-08-09
Abstract: A mechanical pencil has a front sleeve, a cap rotatably and detachably mounted at the rear end of the front sleeve, and a lead advancing mechanism contained in the front sleeve. Rotation of the cap actuates the lead advancing mechanism to advance a lead. The mechanical pencil prevents breakage of lead and has low manufacturing costs. A rotation cam mechanism is disposed behind the lead advancing mechanism for advancing lead. The rotation cam mechanism has a rotation cam for rotating in accordance with rotation of a cap and a cam sleeve biased to engaged the rotation cam. An inside diameter of the front end of the cam sleeve is larger than an outside diameter of the rear end of the lead advancing mechanism so that the rear end of the lead advancing mechanism is inserted into the front end of the cam sleeve with a clearance in the radial direction. An inside diameter of the rear end of the lead advancing mechanism is larger than the outside diameter of a lead to establish a clearance there also.      Due to these clearances, if the pencil is dropped, lead is not broken due to distortion of the lead advancing mechanism.

Title: Method and structure for evaluating and enhancing the performance of cache memory systems
Inventor: SALSBURG MICHAEL A
IPC: G06F12/08
Filed: 1994-07-13
Abstract: Method     and structure for collecting statistics for quantifying locality of data and thus selecting elements to be cached, and then calculating the overall cache hit rate as a function of cached elements. LRU stack distance has a straight-forward probabilistic interpretation and is part of statistics to quantify locality of data for each element considered for caching. Request rates for a additional slots in the LRU are a function of file request rate ant LRU size. Cache hit rate is a function of locality of data and the relative request rates for data sets. Specific locality parameters for each data set and arrival rate of requests for data sets are used to produce an analytical model for calculating cache hit rate for combinations of data sets and LRU sizes. This invention provides algorithms that can be directly implemented in software for constructing a precise model that can be used to predict cache hit rates for a cache, using statistics accumulated for each element independently. The model can rank the elements to find the best candidates for caching. Instead of considering the cache as a whole, the average arrival rates and re-reference statistics for each element are estimated, and then used to consider various combinations of elements and cache sizes in predicting the cache hit rate. Cache hit rate is directly calculated using the to-be-cached files' arrival rates and re-reference statistics and used to rank the elements to find the set that produces the optimal cache hit rate.

Patent CA-2173961-A1 (CA)
Inventor: DRUKIER ANDRZEJ K
IPC: C12Q1/68
Filed: 1994-10-12
Abstract: For isotopes decaying by capture of an inner shell electron by the nucleus, coincident emission of X-ray and gamma photons may occur. The X-ray results from the drop of an outer shell electron to fill the S shell. The gamma results from the transition of the excited daughter nucleus to a lower energy state. The invention disclosed is a Coincident Gamma and X-ray Detector (CGXD) which achieves extraordinary background rejection by a synergistic combination of coincident counting and other background suppresion measures. Whereas the background registred by single gamma counters is of the order of 20-40 counts per minute, a CGXD optimized for the electron capture radioisotope I125 has a background of about one count per day.

Title: Directional microphone housing arrangement
Inventor: MCATEER JEFFREY PHILLIP
IPC: H04R1/34
Filed: 1996-04-23
Abstract: A unitary housing made from an acoustically-opaque, resilient material is employed with a microphone element to form a directional microphone assembly. The microphone element includes a diaphragm which moves under the influence of sound pressure applied to its opposite surfaces to generate an electrical signal which is proportional to the differential sound pressure. The unitary housing includes a first acoustically-transparent channel for communicating sound pressure from a first port in the unitary housing to one surface of the diaphragm, and a second acoustically-transparent channel for communicating sound pressure from a second port in the unitary housing to the other surface of the diaphragm. An illustrative embodiment, the unitary housing comprises a unitary small "boot " having a surface including the ports for coupling acoustic energy to the acoustic channels, an inner chamber for housing the microphone element and a predetermined opening in a surface of the boot for accessing the inner chamber. The microphone element is inserted into the inner chamber via the predetermined opening, which is dimensioned to seal itself around the inserted microphone element so that acoustic energy cannot leak out of or into the inner chamber through the opening. The distance between the ports is relatively short so as not to change the directivity pattern or frequency response of the resulting microphone assembly. In the illustrative embodiment of the invention, the unitary housing is molded from Ethylene-Propylene-Diene-Monomer with Polypropylene which is a rubber-like material that is resilient. It forms an excellent seal around the perimeter of the microphone element so that sound pressure in one channel does not leak into the other. Moreover, the rubber-like material forms a seal with the surface of sound-input equipment where it is housed.
