Abstract: A cutting, delimbing and trimming grapple for a multifunction tree harvester, characterised by that the feed rollers (1) or alternatively the drive wheels which propel the trunk against the delimbing cutters are located on support arms (10 and 11) operated by hydraulic actuators or similar devices. The delimbing cutters are placed to present short leverage arms (dimensions C and B) and are situated close to the feed rollers, so that the forces arising from delimbing and the acceleration and deceleration of a trunk are not directed against the pin (17) joining the support arms (10 and 11), and do not bear with the leverage arms (A and E) resulting from the dimensions of the grapple frame. Then the frame and support arms (10 and 11) may be manufactured on the basis of a lighter design.

Filed: 1990-07-26
Granted: 1991-02-03
Abstract: A method of producing fresh meat is disclosed, in which substantial  moisture  loss during  production  is  effectively reduced.   The method  comprises the steps of applying liquid to the surface of a carcass; subjecting the carcass to a supercold environment for a period of time sort enough to substantially prevent freezing of the outermost layers  of the flesh of the carcass,  but long enough to allow for formation of an ice layer around the carcass.  Once the ice layer is formed, the carcass is passed  into  refrigeration  chamber  for  further  cooling.  The carcass is kept in the refrigeration chamber for a period fo time long enough to lower the temperature of the flesh to a point where substantial deterioration of the flesh is prevented,  but short enough to prevent freezing of the flesh.

Title: Electric dental flosser
Inventor: POULOS LOUIS
IPC: A61C15/04
Filed: 1992-12-21
Granted: 1995-01-17
Abstract: A lighted electric dental flosser with a rechargeable battery compartment includes a motor casing, interchangeably individualized head units, and disposable plastic floss tips that snap mount within the hinged end of the head unit.   The floss tips exhibit bidirectional flossing motion provided from a motion translation system including an eccentric cam,   a yoke, and an output shaft with a cam follower mechanism that follows a generally Z-shaped tracking surface with a vertical track component and a horizontal track component enabled by the yoke to complete the resulting "Z" movement.  The floss tips have a molded-in filament and are molded from a shock absorbing substance which absorbs the vertical component of the "Z" shaped motion upon the application of pressure to the filament thereby outputting horizontal motion until the filament passes through the contact area between two teeth.  In an automatic mode, an infrared sensor in the head activates the motor when the line of sight between infrared sensors is broken by the filament approaching a contact area between two teeth.
