Patent CA-2052143-A1 (CA)
IPC: A01C5/06
Filed: 1991-09-24
Abstract: A depth gauging adjustment mechanism includes a spring-loaded handle which pivots about a common axis with the depth gauging wheel arm on an opener assembly.  The handle has two transversely located pins, and the back of the opener assembly has notches on a radius struck on the axis for receiving the pins.  The wheel arm and thus the planting depth are maintained by the handle.  Each handle position represents a different planting depth which can be adjusted easily with one hand by pulling the handle against the bias, repositioning the pins and then releasing the handle.  The wheel arm is freely rockable downwardly from the depth adjusted position to facilitate handle movement when the opener assembly is raised from the ground-working position.

Title: Torque limiter device for gas hydraulic actuators
Inventor: ZILIANI RINO
IPC: F16K31/12
Filed: 1992-01-15
Abstract: - i -ABSTRACT  of the DISCLOSURE       Used in conjunction with a gas hydraulic actuator, the device is designed to prevent the transmission of stress-inducing torque to a valve by unloading excess gas pressure against a spring bias whenever the difference in pressure between the gas directed into one chamber and the oil directed into another chamber rises above a certain value, determined by setting the spring at a suitable tension; in the event that a valve operated by the actuator should become stuck, the torque limiting action disallows the application of excessive stresses, thereby protecting the valve from damage or even total breakdown.

Abstract: ALFRED TEVES GMBH            SUMMARY            PROCESS AND SYSTEM FOR GATHERING AND EVALUATING MEASURED                          DATA     In a process and a system for multi-channel gathering and evaluation of measured data the measured data channels are distinguished into analog data channels and into digital or into so-called event channels. By means of a signal derived from the events, or rather from event signals, and processed in the event channels the analog measured data will synchronously be sampled, i.e. picked up, converted into a digital value and stored. Each time there will be stored an identification number of the event signal triggering the sampling operation, or rather of the corresponding event channel, the phase time between this sampling signal and the preceding sampling signal, the appertaining sampled measured data and the time sequence of the sampling operations.            The signal triggering the synchronous sampling operation is preferably formed by OR-linking of all event signals which are scaled down, if applicable.            (Fig. 1)

Abstract: O.Z. 0050/42562 Abstract of the Disclosure: An improved process for the preparation of polyenes by the Julia reaction comprises carrying out the allylation of the anion of an allyl aryl sulfone generated a strong base, and the elimination of arylsulfinic acid to form a double bond in the same inert polar solvent which is immiscible with water, preferably in a ketone of the formula I                         R1-CO-R2               (I) where R1 and R2 are each straight-chain or branched alkyl of 2 to 4 carbons, or R1 and R2 together are tetra-methylene or pentamethylene. The process is particularly important for the preparation of vitamin A derivatives. In the preparation of vitamin A aldehyde, for example, it is advantageous to use the same alkali metal alcoholate as strong base in both stages so that the conversion can be carried out as one-pot reaction.

Title: Equipment for respiratory protection against pollutants
Inventor: SCHEGERIN ROBERT
IPC: A62B18/00
Filed: 1992-08-19
Abstract: An Equipment  for  respiratory protection against pollutants, for use at low altitude comprises a face cover fitted with an atmospheric air supply comprising a filter, a rotary fan to compensate for the head loss due to the filter, and a flexible hose, as well as a self-contained electric  power  source  for  energizing  the  rotary  fan, supplying a rated voltage V0. The fan supplies, under its rated voltage V0, an air flow rate higher than that neces-sary for the wearer when the latter is in rest condition, but far lower than the air flow rate required in case of abnormal activity. A pressure sensor causes a temporary increase in the voltage applied to the fan when the over-pressure prevailing in the face cover with respect to the surrounding is lower than a predetermined value.

IPC: A61G3/06
Filed: 1992-08-25
Abstract: ABSTRACT OF THE DISCLOSURE   An elongated ramp is provided for longitudinal extension and retraction relative to a predetermined margin of a support structure therefor.   The ramp includes a longitudinally short base end section and a considerably longer outer end section and the support and ramp include coacting guide structures for sup-porting and guiding the ramp during extension and retraction thereof, the outer end section of the ramp being automatically disengaged from the support and guide structure responsive to the ramp approaching its fully extended position.  In a first form of ramp, a biasing structure is operatively connected between the sections yieldingly resisting downward swinging of the outer end section as it disengages from the support and guide structure during extension of the ramp and the biasing structure is operative to counteract a major portion, only, of the force of gravity acting upon the outer end section to swing the outer end thereof down-wardly  as  the  ramp  moves  to  its  fully  extended position.  A second form of ramp structure is provided for gently lowering the outer end of the ramp to the ground after full ramp extension and also for raising the  outer portion  of the  ramp  to  an  essentially horizontal position prior to ramp retraction.
