Title: Thermoforming flexible plastic foam shells
Inventor: MENARD MICHAEL J
IPC: B29C51/04
Filed: 1987-08-13
Granted: 1991-11-05
Abstract: Abstract of Disclosure An improved method and apparatus for rapidly forming plastic foam shells from a flexible foam sheet.  The foam sheet is i??er mittently passed through a radiaent heating unit and is rapidly heated on both sides to 130-250°F to soften the foam.  The heated foam sheet is immediately passed through a forming die unit in which the foam sheet is deformed partly into the die cavity by withdrawal of air from the cavity, and a die plug descends and final forms a shell while rapidly cooling the foam shell to below its plastic deformation temperature.  By this forming method and apparatus. ethylene-containing foam shells having a depth 10-25 times the foam sheet initial thickness are rapidly formed at 10-30 cycles/minute.

Title: Tdma system capable of individually controlling electric power of bursts
Inventor: SABURI AKIO
IPC: H04B7/185
Filed: 1988-01-18
Granted: 1991-08-27
Abstract: Abstract of the Disclosure:       In a TDMA system comprising a plurality of earth stations communicable with one another by the use of a plurality of carrier waves through a transponder of a satellite which has an available electric power level, bursts carried by the carrier waves are individually and flexibly controlled in accordance with a burst time plane so that selected ones of the carrier waves have on the satellite a total electric power level which does not exceed the available electric power level at any time. The bursts therefore may have different power levels in dependency upon scales of the earth stations, traffics carried by the bursts, and receiving conditions at the earth conditions. The selected carrier waves can be transmitted or received by frequency hopping. Such control of the power levels is carried out in each earth station by the use of a combination of an attenuator (67) and an attenuation control circuit (71) operated in accordance with the burst time plan.

Granted: 1993-10-12
Abstract: A B S T R A C T  O F  T H E  D I S C L O S U R E    In the  case  of known apparatuses  for  filleting fish,  such as  trout,  the eviscerated fish is placed astride a saddle which is displaceable longitudinally between the two blades of a pair of circular knives. The distance between the two circular knives is fixed. In the present invention, in order to be able to adapt the distance between the two circular knives to the thickness of the plate-like saddle, which, in turn, is replaceable for adaptation to different sizes of fish, the  distance  between  the  two  circular  knives  is variable.  To this end the knives are each mounted upon a lever adapted to pivot about a vertical axis,  the lever carrying a sensing arm comprising a roller which bears against a lateral surface of the saddle.

Title: Method for producing prosthetic constructions
Inventor: BRAJNOVIC IZIDOR
IPC: A61C13/003
Filed: 1988-05-16
Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE          The disclosure relates to a method for producing oral and extraoral prosthetic constructions of composite material with considerable fibre content, and in particular to the production of jawbone anchored dental bridges of reinforced plastic.  A number of mutually retracted tubularly braided fibres, possibly in combination with continuous fibre strands, so-called roving, together constitute a fibre system which is packed in a tube, hose or the like which is sealed and serves as outer packaging.  A suitable matrix material, for example acrylic plastic, is injected into the hose for impregnation (wetting) of the enclosed fibre system, whereafter the hose is removed.  The fibre system is then polymerized to form a finished prosthesis blank in a mould.          The prosthesis blank is then given suitable form and appearance by conventional after treatment.

Title: Method for producing powder forged components
Inventor: WEBER MANFRED
IPC: B22F5/00
Filed: 1989-02-27
Granted: 1993-11-23
Abstract: ABSTRACT            A powder forged component consisting of two separate parts is obtained by pressing to final shape a one piece powder preform,  followed by sintering, forging,   cooling  and  separation  into  individual parts.     According  to  the  invention,   prior  to sintering and at the point of separation between the individual parts,   the preform is povided with an incipient notch which, between sintering and forging, is given a protective coating,  more particularly a layer of oxide.   When forging the preform to final shape,  the notch is closed,  whereupon the component is cooled and is then separated by fracture into its individual  parts.     The  method  according  to  the invention may be used,  for example,  for producing a connecting rod having a divided big end and,  after the rod has been cooled, the holes for the connecting rod bolts are prepared in the big end,   and the connecting rod bolts and nuts are assembled loosely in the holes,  after which the parting surface in the big  end  joint  is  produced.     This  considerably simplifies the process and at the same time enables to give more accurately fitting individual parts.
