Patent CA-2023425-A1 (CA)
IPC: H04N1/32
Filed: 1990-08-16
Abstract: In the existing facsimile apparatuses with telephone function, those having the function of storing the received acoustic signal when the subscriber is absent are known.          Hitherto, modulation/demodulation and memory of image data and acoustic data have been executed in independent com-positions, and the structure was large and complicated.          Besides, various pieces of voice information sent out upon arrival of acoustic signals were also processed in independent compositions, and versatile use was difficult.          In the invention, the acoustic data is processed by using image data processing apparatus, and acoustic data is stored in image memory.  Moreover, when storing image data and acoustic data in image memory, each memory region is set dynamically.  Further, the voice data sent out upon arrival is stored in part of the program memory controlled by the CPU.  As a result, the structure is reduced in size and simplified, and complicated combined processing of voice signal being sent out may be realized.

Abstract: The present invention relates to a method and a device de-signed to arrange and pack plants (13) and their respective root lumps (14), which plants have grown in a seedling unit (12) containing a large number of plants and soil lumps, arranged in a plurality of rows and lines adjacent each oth-er in a uniform, rectilinear check pattern, some of the soil lumps possibly missing a plant or containing an only badly developed plant due to a failed seed germination, a reduced growth or due to other circumstances, which empty soil lumps and soil lumps with not healthy plants respec-tively axe removed from the healthy plants, subsequent to which the packed healthy plants are placed in transport con-tainers. The healthy plants are gripped by gripping elements (20) and are placed with the same pattern as they had in the seedling unit, i.e. including possible gaps for removed empty soil lumps or not healthy plants, in channels (45) with a separate channel for each row. Subsequently the plants are conveyed in the channels from an input end to-wards an output end. The gaps are eliminated in said chan-nels not later than in said output end, subsequent to which a certain number of plants, brought together in this way, corresponding to a certain length of the channels in the output end, are removed from the channels and placed in the transport container.

Patent CA-2034307-A1 (CA)
Inventor: EKMAN THURE
IPC: F16L37/32
Filed: 1991-01-16
Abstract: A coupling part constituting the male or female part in  a  quick  coupling  comprises  an  inner,  longitudinally displaceable unit positioned in an outer part of the coupling part, the inner unit being adapted in a deactivated position thereof to confine the media pressure in a first chamber arranged in the outer part of the coupling part and in an actuated position to open or keep open an access for media to a second chamber in the outer part.  Pressure-reducing members actuable upon coupling together of the male and female parts and allowing for the coupling even at high media pressures, and including a lead-off channel for media pressure and a shut-off element positioned in the channel, and actuable by the end face of the other coupling part through an actuation member.  The actuation member is sealed-off or positioned in the coupling part in order to prevent lead-off media from reaching the end face of the coupling part. The lead-off channel on both side of the shut-off element is connectable to the first and the second chambers and upon actuation of the pressure-reducing member,  the  first  and  second  chambers communicate through lateral connections in the inner unit the lead-off channel and the opened shut-off element whereby accompanying decompression of  the pressure  in  the  first chamber facilitates the longitudinal displacement of the inner unit, as a result of which it is possible to obtain leakage-free connection of the coupling parts in the presence of any media pressure.

Title: Toy vehicle wheel and axle assembly
Inventor: MULLANEY SEAN T
IPC: A63H17/267
Filed: 1992-02-03
Abstract: ABSTRACT       Toy vehicle wheels are each mounted on an axle having a gear with each of the wheels having a pair of diametrically opposed arcuate segments.   Each   of the arcuate segments includes an inwardly extending member with each member    including a rack that is kept in engagement with an opposed toothed side of the gear.   A coiled spring biases the two opposed arcuate segments toward each other.  With a motor driving the axle in one direction, the wheel is initially rotated with the opposed arcuate segments in a first   position proximate each other until the wheel encounters an impediment that stalls rotation of the wheel so that continued rotation of the axle in one direction drives the segments away from each other.  For enhancing the visual effect of the arcuate segments being moved away from each    other, edges  of  the  arcuate  segments  are  provided  with projecting parts that are  obscured when the  arcuate segments are in the first position proximate each other.

Abstract: A telescopic manhole or storm drain installation includes  a riser assembly provided with an upper section and adjacent  lower section  the  former of which comprises a side wall  defining  an inverted frustoconical configuration while the latter provides  a vertically  disposed member having external  threads  cooperating with a stationary threaded collar.  To prepare for resurfacing of a roadway or the like, no excavation about the riser is  required prior  to its elevation by use of a tool  which  engages  mating receptors located within the interior of the riser.  Rotation  of the  tool  rotates the riser assembly within the threads  of  the collar  until  the new, elevated plane is achieved.  The  effort required to displace the riser is minimal due to the movement  of its  outer surface away from any grouting or roadway base  previ-ously  abutting the riser.  Risers with non-circular  upper  sec-tions and lids are accommodated by forming the riser of  separate upper and lower sections having a sliding joint structure  there-between.  Synthetic polymeric materials are proposed for both the risers and lids having a somewhat similar external  configuration but employing lids provided with a body of substantial height and formed  with  a  dome-shaped bottom surface  such  that  vertical compressive forces are transmitted radially thereby and  conveyed to the surrounding riser side wall.
