Abstract: Abstract of the Disclosure Clutch Brake Steering Control Clutch-brake steering systems are known to operate on track vehicles which are highly reliable and cost effective, but lacked the fine degree of controllability found in the more expensive differential steering.  An electronically controlled clutch brake steering control apparatus provides control signals to electrohydraulic proportional valves for accurately modulating the control pressures of a set of steering clutches and brakes.  A pair of sensors deliver signals, which are indicative of track speed, to the control apparatus.  The apparatus acts to adaptively adjust selected ones of the valves to maintain a desired track speed differential.  Thus, the controllability of the clutch-brake steering system is enhanced to effectively compete with more expensive and complex systems.

Title: Biocompatibility of solid surfaces
Inventor: GUIRE PATRICK E
IPC: A61F2/00
Filed: 1987-10-16
Granted: 1992-07-14
Abstract: ABSTRACT      The biocompatibility of biomaterials having solid surfaces is improved through coating the same with biocompatible agents.  The method for modifying the solid surface to improve biocompatibility employs molecules of a biocompatible agent and a chemical linking moiety possessing a photochemically reactive group capable upon activation of covalently bonding to the solid surface and possessing a different reactive group as capable upon activation of covalently bonding to separate molecules of the biocompatible agent.  One of the groups is unresponsive to activation by a stimulus to which the other group is responsive.  The method comprises applying stimulus to sequentially activate the groups and covalently bind the different reactive group of the linking moiety to the molecules of the biocompatible agent and to photochemically covalently bind the linking moiety to the solid surface with a sufficient population density to enable the molecules of the biocompatible agent to effectively shield the solid surface and to provide a biocompatible surface.

Title: Universal translational and rotational film drive mechanism
Inventor: LEIB KENNETH G
IPC: G03B15/00
Filed: 1988-02-25
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE      Prior art optical correlator systems can perform only translation or rotation.  Moreover, images obtained from these prior art systems are blurred due to movements of the target.  In the present optical correlator system, to compare symbols on a particular frame of a film with predefined symbols stored in a memory, a novel driving mechanism which can both translate and rotate the film is used.  The driving mechanism includes a translation device which has a plurality of gears and rollers mounted in a platform within a housing which may be filled with a fluid having an index of refraction corresponding to that of the film.  Motors are coupled to the housing for translating and rotating the driving mechanism so that selected symbols on the film may be compared both linearly and rotatively with predefined symbols.  The driving mechanism may further by used as an image motion compensator for eliminating blurring caused by target movements.

Granted: 1994-05-24
Abstract: Abstract of the Disclosure A method and apparatus for allocating bandwidth in a broadband packet switching network are disclosed. The invention utilizes channel groups (112) which may be defined as a set of parallel packet channels that act as a single data link connection between packet switches (110). In accordance with the invention, bandwidth is allocated in two steps. At virtual circuit setup time, bandwidth is reserved in particular channel groups. At transmission time packets are assigned to individual channels within the groups, illustratively, using a coordination mechanism in communication with the input ports of the appropriate packet switch. The bandwidth allocation technique, known as multichannel bandwidth allocation, leads to increased throughput and reduced packet loss probabilities.

Abstract: Abstract Method of and Circuit Arrangement for Guiding a User of a Communication or Data Terminal To guide the user of a terminal, it is known to output the same prompts in the correct sequence, e.g., on a screen.            According to the invention, flexible guidance is pro-vided to different users on the basis of user data which is determined during the predetermined sequence of user actions and compared with stored reference data.            The time from the output of a prompt to the execution of an action by the user is measured, and the number of user errors per prompt is determined. The data thus ob-tained is compared with reference data characteristic of an average user. A user rated as unpracticed (i.e., below average) is then given more detailed prompts than an average user, and a user rated as practiced (i.e., above average) is given fewer or no prompts.

Abstract: Attorney's Docket No. 8010 CAN     INVENTOR:  CHRISTOPH LINK          INVENTION: HEATABLE CONTROLLED DEFLECTION ROLL     ABSTRACT OF THE DISCLOSURE     A heatable controlled deflection roll contains hydrostatic support elements, each of which is supported in a pressure chamber and displaceable in a predetermined support or pressing direction.  Heating of the rotatable roll shell or jacket of the controlled deflection roll is accomplished by infeeding a heated hydraulic heat carrier medium to bearing pockets of the hydrostatic support elements.  This infeed of the  heated  hydraulic  heat  carrier  medium  is  effected operationally separate from the provision of the pressure chamber with hydraulic pressurized fluid medium colder than the heated hydraulic heat carrier medium.  The infeed of the hydraulic heat carrier medium and the infeed of the hydraulic pressurized fluid medium are thus accomplished via separate lines without thermal stressing of associated regulating valves and pumps and without a viscosity reduction of the hydraulic pressurized fluid medium, such viscosity reduction resulting in a  loss  of hydraulic pressurized  fluid medium.   In one embodiment of the hydrostatic support elements there are provided cavities which can be supplied with the hydraulic heat carrier medium separate from the infeed of the hydraulic pressurized fluid medium.   In another embodiment of the hydrostatic support elements the infeed of hydraulic heat carrier medium is accomplished through the pressure chamber by a tubular-shaped sleeve sealingly displaceable relative to the pressure chamber.
