Title: Extrusion process and apparatus for low contaminant cable insulation
Inventor: MARIN CARLO
IPC: B29C48/38
Filed: 1992-11-26
Granted: 1995-10-17
Abstract: Method and apparatus for applying a layer of insulation around an electrical cable core in which the contaminant size is not greater than about 200 microns.  Unplasticized insulation material, such as polyethylene, is supplied to an extruder which forces the material through a filter which prevents the passage of contaminants having a size greater than about 200 microns and in which there is a pressure drop.  The filtered material is delivered to a pump which increases the pressure thereon and forces it through a static mixer at the output of which the filtered material is delivered to the cross-head of extrusion apparatus which applies the filtered material to the cable core as it is advanced longitudinally.  If the insulating material is to be cross-linked by a cross-linking agent, the agent is injected into the filtered material between the pump and the mixer.

Abstract: In a method and apparatus for analysing an electronic image signal, the signal is treated as representing one or more cells each comprising a plurality of pixels. A set of pointers is generated and sequentially set according to characteristic values related to detailed image content. The pointers are used to address a memory array and for successive frames, the values of an address in each array row indicated by the pointer corresponding to that row is updated. In this way, for each frame the characteristic values can be accumulated so that in a single operational mode, both a time history of the image, stored in a memory, is updated and an indication is produced indicative of the occurrence or non-occurrence of an event not associated with image background. The characteristic values can be generated by randomly or pseudo-randomly selecting pairs of pixels and for each, generating a binary signal depending on whether or not the intensity of incident light on a predetermined one of the pair is greater than the intensity on the other. Over all the rows, the values in the addresses being updated can be summed, as well as the maximum value in each row. The ratio of the two sums can be time weighted averaged with respect to the ratios obtained from previous frames. The ratio is compared with the average and the result used to determine the occurrence or non-occurrence of a significant event within the image.

Granted: 2002-05-21
Abstract: The present invention is an apparatus and method for performing a coagulation time test on a sample of blood wherein the blood (16) is deposited in a fluid reservoir (18) and disposable cuvette (12). Within the cuvette (12) is formed a capillary conduit (30) having at least one restricted region (44). The cuvette (12) is inserted into a testing machine (14) which engages the cuvette (12) and draws blood (16) from the fluid reservoir (18) into the capillary conduit (30). The blood in then caused to reciprocally move within the capillary conduit (30) whereby the blood (16) is forced to traverse the restricted region (44). The testing machine (14) measures the time required each time the blood (16) is caused to traverse the restricted region (44). When a measured time is a predetermined percentage longer than an immediately preceding time, coagulation is considered to have occurred and the overall coagulation time is displayed to the operator.

Abstract: A vacuum tube for handling an r.f. signal having a predetermined frequency range comprises a linear electron beam emitting cathode, a heater and a non-electron emissive current modulating grid. The grid is positioned from the cathode by the distance an emitted electron from the cathode can travel in a quarter cycle of the r.f. signal. Outer and inner coaxial metal tubes forming a resonant line of a signal coupler are respectively connected to the grid and cathode so electrons passing through the grid are in bundles in an interaction region between an accelerating anode and the grid. Ferrite tiles absorb r.f. fields in the interaction region. In one embodiment a signal coupling loop is between metal tubes at an end of the tubes spaced 3.lambda./4 from the grid and cathode. In a second embodiment the coupler includes a low voltage coaxial line having an inner conductor connected to a first metal face, spaced from a second opposed metal face by a solid dielectric. The coaxial outer conductor is connected to a third metal face, spaced from a fourth opposed metal face by the solid dielectric. The third and fourth faces surround the first and second faces. The first and third faces are at DC ground potential while the second and fourth faces are at high negative- DC voltages. The second and fourth faces are respectively at common ends of interior and exterior coaxial metal tubes forming a .lambda./2 coupler. Other ends of the tubes are connected to the cathode and grid. Bias leads for the grid and cathode are connected to the exterior and interior tubes at positions .lambda./4 from the grid and cathode, while a heater lead goes through the interior tube at a position .lambda./4 from the grid and cathode.

Patent CA-2135682-C (CA)
Inventor: DEPUE STEVE
IPC: B60G11/04

Granted: 1999-10-26
Abstract: The present invention relates to a high mobility suspension system for vehicles travelling in a harsh off-road environment. In particular, the suspension system can be mounted on a trailer and consists of a cam mounted on a cam shaft for variably deflecting a leaf spring that is mounted to the frame of the trailer. A swing arm is connected between the axle of the wheel and the cam shaft, such that when the trailer is loaded the wheel is deflected which in turn pivots the swing arm and causes the cam shaft to rotate. As the cam shaft rotates the cam deflects the leaf spring based on a ratio of the actual direct trailer loading. The load rate of the suspension system can be customized by modifying the configuration of the cam member and the swing arm to achieve either a linear, progressive or digressive load rate, or any combination of these rates. The present invention enables the trailer to have a compliant load rate yet maintain a compact suspension design by reducing the spring deflection requirements.

Abstract: Un système informatique à processeurs multiples comprend une logique de mise sous tension tolérante aux défauts et servant à trouver un processeur central (CPU) en opération, afin qu'il fonctionne en tant que CPU0 logique. Chaque microprocesseur possède une désignation d'emplacement physique restant constante. Quand le système est mis sous tension, la totalité des CPUs, à l'exception du CPU situé dans la tranche physique 0 (CPU P0), sont placés initialement en état de sommeil inactif. Le microprocesseur de l'emplacement physique 0 exécute son test automatique à la mise sous tension (POST) et, si le CPU fonctionne correctement, il est désigné en tant que CPU0 logique (CPU L0). Le microprocesseur réveille ensuite les CPUs restants et initialise le reste du système informatique. Si le CPU P0 ne fonctionne pas correctement, le système, après une durée déterminée, réveille le processeur de l'emplacement physique suivant et répète le processus de test du CPU. Le processus se répète jusqu'à ce qu'on trouve un microprocesseur opérationnel pour remplir les fonctions de CPU L0.
