Patent CA-2047746-C (CA)
Title: Synchronous adjusting device for office chairs or the like
Inventor: ROERICHT HANS
IPC: A47C1/032
Filed: 1990-12-21
Granted: 2002-02-19
Abstract: A synchronous adjusting device is proposed as a chair mechanism for office chairs, seat furniture or the like, which is constructed extremely simply and with few mechanical means and which, if appropriate, can do without additional force accumulators. At the same time, the restoring movement of the back part wall take place as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this, the back part (7) is mounted rotatably relative to the seat part (5) at a distance in height. The leaning force (9) of the user at the back leaning point (10) is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part (7).

Title: Method and apparatus for sub-span interpolation
Inventor: MINNICH THOMAS
IPC: G05B19/4103
Filed: 1991-08-02
Granted: 1996-11-26
Abstract: A method and apparatus for machine member motion control are provided which reduce position path errors in sampled data motion control systems. Position commands defining locations of a moveable machine member are periodically produced at a predetermined interval as is conventional in sampled data motion control. Intermediate position commands are produced at a predetermined sub-interval less than the predetermined interval in response to a parametric function relating member position and time, the parametric function being continuous through positions defined by the position commands. The intermediate position coordinates are computed as the sum of products of coefficients and coordinates of selected member position commands. To reduce processing time, the coefficients are computed and stored in advance of execution of motion for recall as motion progresses. Where a parabolic function is used to produce intermediate position commands, the sum of products of coefficients and, respectively, past, present and target coordinates are used to compute intermediate positions between the present and target positions.

Filed: 1992-08-28
Granted: 1997-11-04
Abstract: A radio telephone apparatus comprises a time specifying unit, a time measuring unit, a call controller, and an auxiliary power supply.  The time measuring unit measures an elapsed period of time to detect a lapse of a specified period of time beforehand inputted to the time specifying unit.   When it is found as a result of the measurement that the specified period of time is elapsed, the call controller limits the call origination.  Also when the main power supply is off,  the time specifying unit and the time measuring unit are powered from the auxiliary power supply, thereby measuring the lapse of time regardless of the on or off state of the main power supply.  Consequently, the call origination can be limited according to the lapse of specified period of time or the arrival of the specified point of time.

Granted: 1997-07-15
Abstract: This invention relates to a modulating controller for controlling two operation terminals,  and more particularly to a device to suppress disturbance to a process when a control signal is switched or when a bias is set.    This invention, in a modulating controller to control a process amount by the total of two operation terminals disposed in parallel, when either of two H/A station devices outputs a manual operation value, provides a device which outputs a value obtained by reducing the manual operation value from the control amount of the process amount to be controlled by the total of two operation terminals as the control operation signal to the other H/A station device and prepares a value almost same with the operation terminal control signal outputted by one H/A station device as the control operation signal for one H/A station device.    And, this invention automatically controls the process amount by either of the two operation terminals disposed in parallel, and in the modulating controller making one side as the backup,  one operation terminal control signal is always tracked to the control operation device when both operation terminals are manually operated.   When switching the other operation terminal to the automatic operation, timing to switch the other operation terminal to the automatic operation and timing to release tracking are delayed.   During which, a device to switch the tracking signal to the output of the other operation terminal is disposed.

Granted: 1996-07-30
Abstract: A method and apparatus for providing improved security for a personal identification number (PIN) in a personal ident-ification and verification system of the type wherein a time de-pendent nonpredictable code is generated at a device in the pos-session of the individual (36), which code is unique to the indi-vidual and this code is communicated to, and compared with a nonpredictable code generated at a central verification compu-ter (46). In this system, the PIN is mixed with the nonpredic-table code before transmission of these values to the central ver-ification computer (38). A nonsecret code (30) is previously transmitted to the central verification computer and is used by the verification computer to retrieve the PIN and independently generate the time dependent appropriate nonpredictable code for the user (74). These retrieved PIN and generated code va-lues are used by the verification computer either (a) to strip the PIN from the transmitted nonpredictable code (42) and the stripped PIN and remaining nonpredictable code are compared with the corresponding retrieved values in order to determine verification (44, 46); or (b) to be mixed and then compared with the mixed PIN and code which is transmitted to the verification computer (144).

Inventor: BILLOT GENEVIEVE B
IPC: A61K38/04
Filed: 1993-07-20
Granted: 2008-12-23
Abstract: Process for preparing microspheres for the prolonged release of the LHRH hormone and of its analogues, the hormone being dispersed in a water-insoluble polymer or copolymer matrix, the solvent evaporation process is characterized by the use of a pair of organic solvents of which one makes it possible more specifically to obtain a homogeneous suspension of the hormone in the pulverulent state by simply stirring and of which the other is slightly water-miscible so as to allow more specifically the microdispersion of the organic phase in the aqueous phase in which the hardening of the microspheres is performed. This process leads to the preparation of LHRH-containing microspheres which are noteworthy for their purity, especially to microspheres with complex matrices, as well as to formulations comprising at least two types of microspheres.

Title: Partial width seeding attachment
Inventor: LONG JOHN DAVID
IPC: A01C7/20
Filed: 1993-10-26
Granted: 1996-03-19
Abstract: A partial width seeding attachment includes electronically controlled solenoids which activate hydraulic flow control valves connected to the hydraulic cylinders on respective implement sections.  Switches in the tractor cab control the rockshaft of one or more selected sections independently of the other sections to raise the openers on the selected section or sections from contact with the soil. An electronically activated flow reversing valve is connected between the source of hydraulic fluid under pressure and the lift cylinder for each of the sections.  Activation of a selected valve after the selective control valve on the tractor is moved to the normal field working position pressurizes the side of the cylinder that raises the openers on the section.  The remaining cylinders operate normally to maintain preselected down pressure on the other openers.  A master raise switch provides implement lift independent of the position of the individual rockshaft control switches.  A latching relay connected to a momentary on switch prevents valve operation without manual switch movement after a power interruption.
