Title: Foot massager
Inventor: SCHORSCH LOUIS O
IPC: A61H23/00
Filed: 1987-01-08
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE     The foot massage machine of the present invention includes a seat which vibrates appreciably and on which the user sits while using the machine.  The combination of a unique mounting of the vibrating plate and a one-piece shell structure for the body of the machine has proven to be particularly advantageous.  The division of the vibratory energy between the seat and the foot plate is determined by the stiffness of the two isolators that are used to mount the vibrating plate.  A first component of the unbalanced force causes the vibrating plate to pivot about an axis  joining the  isolators, while the orthogonal component drives portions of the body, and the walls serve the important purpose of telegraphing the vibrations from the base part of the body to the seat.  The operation of the electric motor is controlled by a coin-operated timer switch.

Title: Process for the preparation of vinylphosphonic dichloride
Inventor: SIEGEL HERBERT
IPC: C07F9/42
Filed: 1987-08-28
Granted: 1992-12-08
Abstract: The invention relates to a process for the preparation of vinylphosphonic dichloride through elimination of hydrogen chloride from 2-chloroethanephosphonic dichloride in the presence of catalysts.  The catalysts used are tertiary phosphines, quaternary ammonium or phosphonium salts or alkali metal or alkaline-earth metal halides. When triphenyl phosphine is used as the catalyst, the reaction is carried out under reduced pressure at a tem-perature of 130 to 166°C and the vinylphosphonic dichlor-ide produced is simultaneously removed by distillation under reduced pressure.  When the other catalysts are used, the process can be carried out at atmospheric pres-sure or reduced pressure and at temperatures of about 130 to 220°C and the vinylphosphonic dichloride produced can be removed by distillation simultaneously with or subsequent to the reaction.

Abstract: Abstract DNA segments which act to increase or activate the expression  of  genes  in  plants  are  described  and characterized.    These  transcription  activating  elements contain  DNA  sequences  from  the  upstream  untranscribed flanking region of the octopine synthase gene (ocs) of the T-DNA of Agrobacterium tumefaciens.  The ocs transcription activating element contains a  first essential  component which has the identifying sequence 5'-ACGTAAGCGTTACGT-3'.          A  second  nonessential  component  having  the  identifying sequence 5'-GATGTTAACATC-3'  contributes to the  level  of gene expression.  Recombinant DNA molecules containing the plant  transcription  activating  element  and  a  plant-expressible gene  under  its  control  are provided.    The transcription  activating  element  described  and  DNA molecules  containing  it  are  useful  in  a  method  for increasing the level of expression of genes in plant tissue.
Patent CA-1300654-C (CA)
Title: Cleats for cross-country skis
Inventor: MCDONALD DAVID R
IPC: A63C7/00
Filed: 1988-03-07
Granted: 1992-05-12
Abstract: Abstract In this invention, a cleat is fashioned in a cavity on the underside of a cross-country ski. The cleat is deployed when the full weight of the skier compresses a spring or a elastic material under the sole of his boot thereby exerting a downward pressure on a rod which transverses the ski and which is attached to the top of the cleat. The deployment of the cleat, therefore, coincides with the thrust or kick of the skier. The deployed cleat prevents the skier from slipping backward while the skier thrusts backward and hence the skier's acceleration is increased. During the subsequent glide the weight of the skier shifts to the other ski so the spring or elastic material decompressesand exerts an upward pressure on the rod which retracts the cleat snugly into the cavity at the bottom of the ski so the glide is accomplished without resistance.

Abstract: METHOD AND APPARATUS FOR EMBOSSING THE INSIDE SURFACE OF A CUP-SHAPED ARTICLE            ABSTRACT OF THE DISCLOSURE          A draw/emboss work station (18) of the invention includes emboss punch apparatus (86) moveable by a lever (340) and a hydraulic system under control of a press slide (34).  Pressure sleeve apparatus (92) is slideable with respect to the emboss punch apparatus (86) and is responsive to force applied to it by the press slide (34). An emboss punch head (96) is moved downwardly into a cup-shaped article  (14)  to bring the article into a draw/emboss die (146) having an interior reduced diameter part  (148).  The emboss punch head (96) then remains stationary and spaced from the reduced diameter part a-predetermined distance to define an annular opening.  The pressure sleeve apparatus (92) including a pressure sleeve (130) is then forced downwardly into engagement with a shoulder (64) on the cup (14), and forces the cup (14) through the annular opening to thereby simultaneously draw the sidewalls of the cup (14) and transfer the design of the emboss punch head (96) to the inside surface of the cup (14).
