Title: Rudder mechanism for ship
Inventor: KANAZAKI KIHACHIRO
IPC: B63H25/38
Filed: 1990-02-12
Abstract: A rudder mechanism for a ship comprises a support bearing fixed to the bottom of a stern of the ship, a rudder shaft with  one  end  rotatably  supported  by  the support bearing, a swayable shaft member connected to the other end of the rudder shaft, and a rudder wing connected to  the  swayable  shaft  member  and  disposed  behind a  propeller  of  the  ship.   The  swayable shaft member and  rudder  wing  form  a  swayable  wing  portion swayable  in  a  ship  backward  direction.  The  swayable shaft member comprises a projection fixed to the rudder shaft or the rudder wing, a projection receiver fixed to the other of them and engaged with the projection, and a rotatable shaft inserted into the engaged projection and projection receiver to enable them to sway relative to each other.  The projection and projection receiver have restriction  faces  for  restricting  the  swayable  wing portion from swaying in a ship forward direction beyond a vertical position and from swaying in a ship backward direction beyond a maximum backward position.    With this arrangement, the rudder wing will not be just behind the propeller of the ship while the ship is sailing, thereby improving the propelling efficiency and fuel consumption of the ship.

Title: Centrifuged material layer measurements taken in an evacuated tube
Inventor: LEVINE ROBERT A
IPC: G01N/
Filed: 1990-02-26
Abstract: Centrifuged material layer measurements are made in an evacuated glass or clear plastic tube which contains a float. When possibly contaminated materials, such as blood, are being tested the use of the evacuated tube allows the measurements to be made without the technician being exposed to the blood. The tubes are large enough to hold approximately one ml of blood, and are filled with an inert gas at low pressure. Dimensional tolerances relative to those of a capillary tube are relaxed for the tube and float due to the larger sample capacity. The cell bands are stabilized by a layer of a flowable material which settles onto the plasma layer during centrifugation and forms a pellicle thereon.

Abstract: The introducer (10) has an adapter (11) with a pair of wings (19,20) extending at an acute angle wherein the wings (19,20) are used in handling, holding and splitting. A splittable catheter (13) mounts in a part of the adapter (11) and extends in alignment with an axis of the adapter (11). The adapter (11) is molded about the splittable catheter (13) tube. A needle and hub (12) are in axial alignment with one another so the needle (22) fits within the splittable catheter (13) coaxial with the axis and the hub (23) removably locks to the adapter (11) to hold the splittable catheter (13) coaxially about the needle (22) during insertion of the needle (22) and splittable catheter (13) with an over the needle (22) technique. Interengagement means (24) on the adapter (11) and the hub (23) lock the axial relationship of the needle (22) within the splittable catheter (13). An apex (21) between the acute of the wings (19,20) is parallel to the passageway therethrough and a weakened line (35) is on a side of the adapter (11) opposite the apex (21) so that force applied to the wings (19,20) to reduce the acute angle thereof will separate the weakened line (35) and the apex (21) initiating tearing of the splittable catheter (13). The method for using and making an introducer (10) includes the steps of holding a winged adapter (11) with the fingers of one hand, inserting the needle (22) and splittable catheter (13) into a blood vessel, releasing the lock between the adapter (11) and the hub (23), removing the hub (23) by withdrawing the needle (22) from the catheter (13) and squeezing the wings (19,20) together to split the adapter (11) and the catheter (13).

Inventor: MARTIN DENNIS R
IPC: G06F11/00
Filed: 1990-11-27
Abstract: A method of pairing disk units in a computer system where  mirroring  is  desirable  is  disclosed.   Where possible,  disk units are paired with other disk units located on a different bus.  This provides the highest level of protection against inaccessible data due to data loss or failure of a component in the computer system. Where this is not possible, the remaining disk units are paired  with  disk  units  located  on  a  different  I/O processor,  a different controller,  or a different disk enclosure.  Where none of these pairings are possible, the remaining disk units fall below the threshold level of protection and therefore cannot be paired within the segment.  Any disk units that could not be paired are placed on a spare list.   Several attempts are made to pair up disk units on the spare list.   If all of these attempts fail,  the paired disk units with the  lowest level of protection are broken apart and added to the spare list, where attempts are again made to pair up the disk units on the spare list. After all units are paired, a pair of disk units is compared with other pairs of disk units to see if the level of protection can be increased by swapping mates.   This comparison of pairs of disk units  is  repeated  until  the  level  of  protection  is optimized. Each time the computer system is started,  a check is made to determine if a configuration change resulted in a lower level of protection.  If so, the user is asked if he would like the disk units on the computer system  to  be  re-paired  to  increase  the  level  of protection.

Title: Diagnostic interpretation of connected sensors
Inventor: KIDDER KENNETH B
IPC: G05B23/02
Filed: 1991-01-09
Abstract: ABSTRACT OF THE DISCLOSURE        A control system receives a condition signal from a sensor specifying by the value of a basic electrical property derivable from the condition signal the level of a preselected condition in a controlled apparatus, and responsive to the condition signal provides a control signal to the controlled apparatus to control the level of the preselected condition.  To permit malfunctions in either the control system or the sensor to be efficiently isolated the control system further includes: an encoder which receives the condition signal and provides a signal digitally encoding the value of the basic electrical property in the condition signal, a display which receives the digitally encoded signal and provides a visible display of the digitally encoded value, and a manually operable selector allowing the operator to gate the signal from the encoder to the display by properly manipulating an element of the selector.  When a malfunction is suspected, the operator manipulates the selector element to gate the signal from the encoder to the display and notes the value of the basic electrical property.  (S)he then measures the basic electrical property in the sensor using an appropriate meter, detaching the sensor from the control system if appropriate.  If the basic electrical property noted in the display is substantially unequal to the basic electrical property measured using the meter, this implies that the sensor is operating properly and the malfunction is probably in the control system.  If the basic electrical property displayed by the display is substantially equal to the basic electrical property measured using the meter, then it is likely that the sensor is malfunctioning.  In a preferred embodiment, the basic electrical property involved may be either electrical resistance or voltage.

Title: Light weight drive shaft
Inventor: SIMON JOSEPH A
IPC: B21K1/06
Filed: 1991-01-22
Abstract: A light weight drive shaft, such as for use as an automotive vehicle engine drive shaft for transmitting engine power, is extruded from a tubular metal blank into an elongated tube having integral center and opposite end sections, with the center section having a thin wall and the end sections having a thick wall. The shaft is formed by inserting a tubular blank within a tubular die having a constricted die throat through which the blank is extruded. A punch having a lead end punch extension, is inserted within the die, against the trailing end of the blank, with its extension extending part way into the blank. Movement of the punch towards the die throat extrudes the blank through the throat, causing the leading portion of the blank to collapse inwardly to form the thick wall end section until continued movement of the punch positions the extension within the die throat. Thereafter, further movement of the punch extrudes the thin wall center section with the punch extension acting as a mandrel, until completion of the desired center section length. Then, the punch is removed from the die end blank and a second blank is inserted in the die and the punch is reinstalled within the die with its extension extending part way into the second blank. Movement of the punch towards the throat now completes the extrusion of the trailing end portion of the first blank, due to the pressure of the second blank, with the trailing end portion of the first blank and the leading end portion of the second blank collapsing inwardly to form their respective thick wall end sections, until the first blank is completely extruded. Once extruded, splines are formed on the exterior of at least one of the thick wall end sections. Thereafter, the cycle is repeated.
