Abstract: ABSTRACT OF THE DISCLOSURE            A power saw has two oppositely reciprocating saw blades guided and supported in a receiving slot in a support plate.    The  blades  are  supported  during  sawing  along shoulders  on  their  outside  by  lower  edges  of  support sections of the support plate.   The arrangement is such that forces generated in operation during cutting press the saw blades together in the area of their teeth.  This prevents saw dust, chippings etc. penetrating between the two saw blades.   Preferably,  the thickness of the saw blade shoulders are not greater than half the thickness of the  saw  blades,  and  preferably  no  greater  than  the thickness of the support section edges.  The teeth of the saw blades may be so ground and arranged that the resul-tant force on the teeth during cutting also forces the saw blades together at their teeth.

Patent CA-1307722-C (CA)
Title: Apparatus for forming variable strength materials through rapid deformation and methods for use therein
Inventor: FERGUSON HUGO S
IPC: C21D8/00
Filed: 1988-03-28
Granted: 1992-09-22
Abstract: Abstract of the Disclosure The invention relates to apparatus and accompanying methods for use therein for forming a material (504), which has high strength and good workability, by rapidly deforming a suitable base metal (501) having a banded structure, such as illustratively a previously cold worked plain low carbon steel alloy, in order to generate a high rate of change in its internal energy which depresses the transformation temperatures of the base metal and thereby induces an allotropic phase transformation to occur therein.  This rapid deformation can be produced through rolling, extrusion or forging and causes an extremely high heating rate to occur at each surface of the base metal. Prior to being deformed, the base metal is maintained at a fairly low temperature, e.g. at or near room temperature. The tooling, preferably rolls, that is used to provide the deformation is maintained at a modestly elevated temperature.  Subsequent rapid deformation of the base metal causes an extremely high heating rate to occur at each surface thereof which, in turn, depresses the upper and lower on heating transformation temperatures at surface regions of the base metal and thereby causes the banded structure of the metal situated in these surface regions to transform into equiaxed grains.  If the heating rate is insufficient to raise the temperature of the core of the base metal, which contains banded grains, to a level that causes metal in the core to transform, then the core will retain its banded cold worked structure.  Consequently, the transformed surface regions (510, 510') will possess an equiaxed grain structure which provides increased ductility; while the core (511) of the material retains its banded (deformed) grain structure which provides high strength.     Hence, the surfaces (512, 512') of the material become soft and ductile while the core possesses considerably higher amounts of hardness, yield and tensile strength than either surface.  This material advantageously exhibits both good workability and relatively high strength.  Alternatively, if the deformation rate is increased, such as by using small diameter rolls, in order to increase the bulk heating rate of the base metal and the appropriate thickness of the base metal has been chosen, then the entire base metal transforms into equiaxed grains.  In this case, the resulting material (404) possesses a ductility and hence workability similar to that of a fully annealed structure.

Title: Paper interleaver for food patty molding machine
Inventor: LINDEE SCOTT A
IPC: A23L17/00
Filed: 1988-06-09
Granted: 1992-03-17
Abstract: PAPER INTERLEAVER FOR FOOD PATTY MOLDING MACHINE   Abstract of the Disclosure A paper interleaver for a food patty molding machine of the kind using a mold plate cyclically reciprocating along a linear path between a fill position and a knock-out position comprises a shuttle connected to the mold plate for synchronous movement along a linear path between a transfer position and a pickup position.  When the mold plate is at its knock-out position and the shuttle at its pickup position, the shuttle pulls a single paper sheet down from the bottom of a storage stack by vacuum; when the mold plate and shuttle are at their respective fill and transfer positions, the shuttle "puffs" the paper sheet up a very short distance to be held by downwardly facing vacuum ports of a fixed paper holder frame, essentially immune to clogging from the food product particles and juices present at the knock-out position.  A molded patty subsequently moves down through the frame to pick up the paper sheet when the mold plate returns to the knock-out position.  A grooved spindle at the paper storage stack cooperates with a shallow tapered groove in the stack support surface to assure a flat configuration for the paper sheets and elimination of paper particles.

Title: Tube connector
Inventor: BARNOACH ITZHAK
IPC: F16L25/02
Filed: 1988-08-02
Granted: 1993-02-02
Abstract: ABSTRACT:     A metal connector for the end of an internally and externally plastics coated metal tube maintains the  metal of  the tube, for example  aluminium, out  of contact with the metal of the connector, for example brass, and thereby  avoids problems of anodic  corrosion.    This  is  achieved  by forming the male portion of the connector with a tapered shant over which the tube end is to be forced, and a shoulder to act as a stop for the tube end, the shoulder being  of such  relatively shallow depth that it abuts the internal plastics coating but not the metal of the tube.

Title: Self-emptying container
Inventor: ABRAM DAVID A S
IPC: B65F1/12
Filed: 1988-10-21
Granted: 1992-08-25
Abstract: ABSTRACT SELF-EMPTYING CONTAINER     The self-emptying container has relatively moveable parts (10, 11, 40, 41) normally secured together by a latch mechanism.  In one embodiment, the container has an upright body (10) and a pivotal base (11).   In an other embodiment the body is a tipping skip or hopper (40) on a pallet base (41).  The latch mechanism (19, 49) comprises a fore and aft flat bar (22, 52) pivoted at one end.  The other end locates below the horizontal limb (29, 59) of an L shaped latch member (24, 54) which is lifted by the flat bar (22, 52) when an upward pressure is applied to-the bar.   That is done via lift apparatus such as a fork lift truck.   The container is raised over a surface (S) and lowered onto that surface to pivot the flat bar (22, 52) upwards causing the latch member (24, 54) to release the relatively moveable parts to empty the container.   In the first embodiment, the container is then raised so that the base pivots open. In the second embodiment the skip body 40 tips forward. During emptying the pressure on the flat bar (22, 52) is removed so that the latch returns to its locking position so that the relatively moveable parts will automatically latch together when the base is raised to its closed position or the skip body tips back to its loading position.

Filed: 1988-10-28
Granted: 1992-06-30
Abstract: Abstract of the Disclosure This invention teaches an electrochromic device in which an electrochromic layer is positioned between two electrodes. The electrochromic layer comprises an organic based bulk material which has been polymerized and condensed supporting electrochromic particles and ion producing particles in fixed but generally distributed positions therewithin. The bulk material permits migration of ions produced by the ion producing particles to and from the electrochromic particles upon change in voltage between the first and second electrodes. The bulk material also prohibits the passage of electrons therethrough when a voltage is applied between the first electrode and the second electrode, whereby an electric field is built up between the first and second electrodes which causes migration of the ions. Also my invention is a method of making a material which can form an electrochromic layer. The method has the following steps. A gel producing organic material is dissolved in a solvent to produce a solution. The gel producing material is one which permits migration of ions therethrough but prohibits passage of electrons therethrough. A finely divided ion producing material is added to the solution. A finely divided electrochromic material is also added to the solution. The solution is thoroughly mixed. The solution is then polymerized and condensed to obtain a gelled material. The gelled material supports the finely divided ion producing material and the finely divided electrochromic material in fixed but generally distributed position therewithin. 2225L
