Abstract: "ARTIFICIAL IMPLANTABLE DENTAL PROSTHESIS ROOT"          ABSTRACT OF THE DISCLOSURE          An artificial root for dental prosthesis such as crowns, bridges and the like is provided.  Heretofore various types of roots have been tried but they suffer from the prin-ciple disadvantage of rejection due to excessive pressure dur-ing use.  They also suffer from loosening due to twisting and tilting during mastication and lack of effective anchoring by the bone healing process.  The present invention includes an implantable plate or winged root portion having an upper cap or shoulder which engages the upper surface of the jaw bone to assist in the support of the implant and to reduce the root load thereon.  The plate or winged root are perforated so that bone can grow through the perforations whereby the implant be-comes permanently ancylosed to the jaw bone.  A slip-on type prosthesis bolt is embedded or otherwise secured to the upper side of the implant upon which the prosthesis may be attached.

Abstract: OPEN TOP REFRIGERATED DISPLAY CASE       WITH STORAGE SECTION     ABSTRACT OF THE DISCLOSURE          An open top refrigerated display case having an upper display portion for displaying refrigerated products and a lower storage portion for storing refrigerated products.  A cooling mechanism is provided for cooling both the display portion and storage portion of the display case.  The refrigerated products which are stored within the case can be either normally refrigerated products kept at a temperature of above 32°F or frozen products maintained at a temperature of below 32°F.  The cooling mechanism includes a mechanism for establishing a refrigerated air band which encircles the display portion of the display case.  This refrigerated air band is established by circulating air through an air conduit which surrounds the display portion and is positioned above the storage portion of the display case.  Mounted within the air conduit is a fan for circulating air through the conduit and a set of evaporation coils for cooling the air passing through the conduit.  Air is expelled from one end of the conduit at an outlet opening located near the top of the display case and such air is propelled across the opening in the display case towards the opposite end of the case where it is received by an inlet opening of the air conduit.  In this manner, air can be circulated by the fan within the air conduit along the conduit and across the opening in the top of the display case thereby forming an air curtain across the top of the display case.          During a refrigeration cycle the air passing along this air band is cooled thereby cooling the display portion of the display case.  In addition, air from the air conduit is diverted before it has passed through the evaporation coils into the lower storage portion where it is directed around the storage portion and flows back into the air conduit where it is recirculated by the fan within such conduit.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and method to permit selective var-iation in the size of the output image derived from digital image signals.   A Reduction Ratio register  is pre-pro-grammed to a count reflecting the image size desired with a Threshold register set to the desired threshold count.  The count from the Reduction Ratio register is  input to an Accumulator  and  summed  with  the  count  left  over  from processing the previous image signals.   The Accumulator count and the Threshold count are compared.   Where the Accumulator count exceeds the Threshold count, the image signal in process is passed on.   Where the Accumulator count is less than the Threshold count, the image signal is deleted and the count from an Additive Reset register is added to the Accumulator.          In an alternate embodiment, a Counter is set to the magnification ratio integer number and pulses a control gate astride the stream of image signals according to the Counter setting to generate additional image signals.  An Add-one  circuit  responds  to  an  Accumulator/Threshold register comparison to temporarily increase the setting of the Counter by one.

Abstract: A FORCE LIMITING DEVICE                   Abstract Of The Invention The invention relates to a force limiting assembly that includes a force transmitting reciprocating output member carried by an actuator member mounted at one end for rotation in a force limiting assembly housing.  A power input member is secured to the actuating member in the housing.  The assembly is provided with a release mechanism secured to the assembly housing and mechanically releaseably secured to the actuating member to thereby permit the actuating member to move axially into the housing.  The axial movement into the housing occurs only when an axial force present in the actuating member, which force is directed towards the housing, exceeds a preset value which results in the sudden release and movement of the actuating member and the power input member into locking cooperation with a portion of the assembly housing.  While the power input member is in locking cooperation with the housing, no further input power may be transmitted from the power input member to the actuating member and the force transmitting output member.  The release mechanism additionally allows the actuating member and the input member to have limited movement in a direction along the actuating member away from the housing whenever a predetermined force is applied to the actuating member in the direction away from the housing.  The input member, when experiencing the movement in a direction away from the housing, cooperatively mechanically locks with a portion of the housing, whereupon no further input power may be transmitted from the power input member to the actuating member and the force transmitting output member.

Abstract: PHF 80.575                  11                 1.8.1981 ABSTRACT:          Interface circuits between injection-logic layers which are superimposed and biassed with different voltages.     For transferring a logic signal between a first stage and a second stage at higher level in an integrated current injection logic circuit formed by superimposed layers which are biassed with different voltages (for example an I2L logic circuit), the collector of a first transistor (10) at the output of the first stage controls the base of a first auxiliary transistor (12), whose collector is connected to the base of a second transistor (13), which provides the connection to the input of the second stage. In order to rapidly drain the charge stored in the base of the second transistor (13), said base is connected to the base of a third transistor (14), whose collector is connected to its base so as to form a current mirror. The switching time of the device in accordance with the invention is thus substantially reduced. Moreover, said device has the special feature that the logic levels are situated on both sides of a reference voltage applied to the base of a second auxiliary transistor (15), which enables it to be used as an interface between different types of logic circuits.          Application: information processing.          Reference: Figure 2.
