Patent CA-1297382-C (CA)
Inventor: EGGERT ULRICH
IPC: F16H61/12
Filed: 1986-12-17
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE A control valve system for controlling the operation of a continuously variable belt-driven motor vehicle transmission includes a first hydraulic pump that supplies fluid to the displacement cylinders of the transmission through a main pressure regulating valve and a transmission ratio control valve as a function of the setting of the manual selector valve and as a function of the torque requirement and speed of the vehicle.  The torque converter is supplied with hydraulic fluid by way of a relief valve which comes into operating in the event of failure of an electronic control unit and a decrease in the vehicle speed.  A first emergency operation on/off valve transmits torque at converter discharge pressure, by way of a second emergency on/off valve, as emergency operation control pressure to a transmission ratio control valve.

Title: Process for the production of a telecentric light beam, device for carrying out this process and process for the production of an hoe
Inventor: KAESER BEDA
IPC: G01B11/10
Filed: 1987-04-01
Granted: 1995-01-03
Abstract: A  light  beam  is  repeatedly deflected  in the  longitudinal direction  through  a  holographic  element  HOE  by  means  of a  rotating  multi-faceted  mirror.   This  HOE  is  so  formed that the beam entering at different angles leaves the HOE as  a  telecentric  beam.    Through  a  further  HOE  the telecentric   beam   is   diffracted  onto   a   opto-electric transducer.   In  the  region  of  the  telecentric  beam  is located  an  object  to  be  measured,  and  the  time  of  the interruption  of  the  telecentric  beam  by  means  of  this object enables the dimension of the latter to be determined. The production of the telecentric beam and the deflection of  the  latter  onto the  transducer  by  means  of  the  HOE allows a simple cost-effect manufacture as well as a simple evaluation  of  the  measurements  with  increased  precision. The manufacture of the HOE is likewise simple.

Title: Casting roll and a procedure for the overhaul thereof
Inventor: LAUENER WILHELM F
IPC: B22D11/06
Filed: 1987-05-13
Granted: 1990-12-27
Abstract: ABSTRACT            Rods are placed into axially arranged grooves of the roll core. These rods protrude radially from the roll surface and the roll shell is shrink-fitted onto the rods. Due to the creeping movement of the roll shell which is a result of periodical heating and cooling thereof, the inside surface of the shell and the inter-facing outside surface of each rod are subject to wear. Whenever this wear has proceeded beyond a tolerable limit the rods are replaced, whereafter a new shell with a normal inside diameter is again shrink-fitted onto the rods. Thereby the rod's and the shell's dimensions must never be changed  The roll core is not subject to wear. Stock-keeping and fabrication are particularly simplified due to the fact that the dimensions of the replacement parts never change.

Title: High density rom in a cmos gate array
Inventor: KHAN EMDADUR R
IPC: H01L27/118
Filed: 1987-11-24
Granted: 1992-09-01
Abstract: ABSTRACT OF THE DISCLOSURE A memory circuit implemented in a CMOS gate array employs both P-channel and N-channel transistors as memory devices.  The use of P-channel memory devices is made possible by providing a level-shifting circuit and voltage reference circuit to compensate for manufacturing process variations and fluctuations in power supply levels.  The reference circuit is made up of a series connection of P-channel FETS that are the same as the memory transistors.  The reference voltage produced by the reference circuit tracks variations in the power supply and reflects changes in manufacturing processes so that they are compensated in the output of the level shifting circuit.   Performance is further enhanced by clocking load FETS that connect the memory transistors to the voltage source, and density is increased by providing two word lines per row of memory transistors.

Title: Pop-in tab container closure
Inventor: COLBERT MATT W
IPC: B65D41/32
Filed: 1987-11-26
Granted: 1991-04-16
Abstract: Abstract of the Disclosure A pop-in tab container lid for sealed association with a container body is disclosed.  The lid includes a closure panel having a severable score line which extends about a portion of the panel and terminates in spaced oppositely disposed extremities to define a depressible tab and a tab hinge portion between the extremities.  The tab has a short stiffening rib and a long stiffening rib extending between the hinge portion and a segment of the score line which is diametrically opposite the hinge portion.  Each rib has an inner end opposing that of the other rib so that the ribs are arranged end to end along a common line.  An outer end of the short rib terminates at the segment of the score line and an outer end of the longer rib terminates at the hinge portion.  The inner opposing ends of the ribs define a weaker area such that when either or both ribs are subjected to a pressing force, the weaker area will bend inwardly towards the container's interior and the ribs will move about their respective outer ends to an inwardly disposed bent position.  Such bending movement will concentrate the pressing force at the segment of the score line to initiate fracturing of this segment and continued application of the pressing force will completely sever the tab about its score line to provide an opening in the panel.  Modifications disclosed have the outer end of the short rib extending beyond the score line and on the score line and another embodiment has two sets of short and long ribs on a single tab.

Abstract: ANCHOR FOR MASONRY VENEER WALLS                Abstract of the Disclosure The anchor includes a stud holder having one end which threadably receives a threaded stud.  A flat tongue-like driving head projects axially from the other end of the stud holder and is formed with an eye for receiving one end portion of a wire tie for establishing a positive lateral load connection between an outer masonry veneer wall and an inner supportive wall having a layer of insulation thereon.  An integral, radially extending flange is formed at the inner end of the driving head and stabilizes the stud holder while the latter is being driven by a power-rotated socket.  When the stud is fully driven, the flange seals a hole drilled in the insulation by the stud holder.  The inner end of the stud holder includes cutting elements which enable the stud holder to drill effectively through both hard and soft insulation.  The eye through the driving head is shaped so as to eliminate the need of establishing precise angular alinement between the driving head and the wire tie.

Granted: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE            An air-adjustable shock absorber is pivotally connected at its ends to  first arms  of a  front and of a  back crank arm system, which are pivotally mounted to the vehicle chassis at the front and back of the same  between the  upper and  lower runs of the endless  track of  the vehicle.  The second arms of the front and back crank arm systems are  connected to  the front  and back portion  of  the  slides  which  engage  the upper surface of the ground-engaging run of  the  endless  track.    The  air pressure within the  shock absorber unit biases the two crank systems in a direction so as to  move the  slides downwardly  from the vehicle chassis.  An air circuit system enables the driver to control the air pressure depending on the load carried by  the vehicle.   The crank systems  are such  that a greater proportion of the load is carried by the back of the suspension.
