Abstract: ABSTRACT OF THE DISCLOSURE         A dental post for retaining a dental restoration in a secured position on a prepared tooth stub, the dental post including a cylindrical elongated pin having grooves disposed about the periphery thereof, the pin being insertable within a bore provided in the tooth stub.  A head portion of the pin projects from the tooth stub to secure the restoration thereon. The head portion includes a substantially conical neck section from which projects a flattened tang.  The tang is substantially wider than the diameter of the pin and is angularly oriented with respect to the elongated axis of the pin.  The head portion provides improved retention of the superstructure upon the tooth stub and permits orientation of the tang in the same angled direction as the angular orientation of the tooth prosthesis so as to be centrally located within the tooth superstructure for improved retention and strength.

Abstract: ABSTRACT             A key telephone system comprised of a key service unit connected to a plurality of local sets via four-wire conductors for providing full duplex signal communication between the key service unit and sets.  signals are carried by a first pair of each of the conductors for unidirectional transmission of signals from each set to the key service unit, and the remaining pair of conductors carries signals transmitted by the key service unit for reception by one or more of the sets.  Four-to-two wire signal conversion and line impedance balancing is effected by one or more trunk circuits of the key service unit in the event one or more of the local sets are connected via the key service unit for communication between the sets and the outside telephone lines.  As a result of separate unidirectional communication paths being provided between individual ones of the subscriber sets and the key service unit, via the four-wire conductors, the inpedance balancing function of the trunk circuits is independent of the length and quality of the four-wire conductors.  Each of the trunk circuits preferably incorporates an electronic telephone circuit for performing the four-to-two wire signal conversion as well as AC and DC termination and loop length gain equalization for signals carried by the outside telephone lines.  The key service unit and subscriber sets of the telephone system areinexpensive, compact and highly efficient as a result of minimizing the number of four-to-two wire conversions therein.

Abstract: Abstract A hand knife of the type having a ring-like rotary driven blade useful for cutting meat and other suitable products; a blade housing for a hand knife; and a circular blade.  The blade housing has a generally circular groove to receive a ring gear portion of the blade while a cutting portion extends from the housing. One arcuate wall portion of the housing is frusto-conical and faces a similarly contoured peripheral portion of the blade ring-gear.  In the preferred construction the housing recess is formed by a cylin-drical wall that surrounds the ring-gear portion of the blade and by a frusto-conical wall that is encircled by the ring-gear portion of the blade.  A blade retainer secured to the handle acts against a radial flange of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing.

Abstract: ABSTRACT OF THE DISCLOSURE          The present  invention is a moisture-insensitive system adapted to couple radio frequency energy at a low impedance from a matched two conductor transmission line, through a vehicle windshield and to an antenna in a manner which minimizes stray radio frequency radiation within the passenger compartment of the vehicle.  The system includes two pair of conducting plates, one pair mounted on each side  of  the  windshield,  each  pair  opposite  the  other pair.  A coaxial feed line is coupled to the inside pair of plates and a matching circuit is connected across the outside  pair  of plates.   A full-size,  unloaded  antenna element is connected to the output of the matching cir-cuit.  A decoupling device, such as a decoupling sleeve or a RF choke, can be used to minimize RF current flow on the shield conductor of the coaxial feed line.   The coaxial cable is coupled directly through the windshield, without an intervening matching network,  so that RF energy at a low impedance is coupled to the outside pair of plates.          This  low  impedance minimizes  parasitic  coupling  of  the feed  system  to  moisture  on  the  windshield,  windshield wipers  and  other  foreign  bodies.   The  elements of  the invention cooperate to minimize the level of stray radi-ation within the passenger compartment of the vehicle and provide, in the illustrated embodiment, a 2.0:1 VSWR band-width that extends from 830 to 880 megahertz.

Abstract: Abstract of the Disclosure A digital peak-hold detector for determining the peak value of an input analog voltage to be displayed on a multiple-element display device detects when the value of the input analog voltage exceeds the value of a ramp-like waveform generated from a counter which repetitively counts down from a number equal to the total number of display elements to zero to generate a compare signal.  A control circuit strobes the count corresponding to the peak value into a storage register when the value of the input analog voltage exceeds the current peak value in the storage register.  A digital comparator compares the current peak value from the storage register with the repetitive count from the counter and outputs an update signal when the value of the count is greater than the current peak value.  The update signal is combined with the compare signal by the control circuit to make the determination whether to update the current peak value.  A time delay circuit causes the control circuit to clear the storage register to generate a new peak value when the current peak value is not updated within a predetermined period of time.

Abstract: Method and apparatus for drilling deep holes in the rock or the like. The apparatus is adapted to be attached to the end of a drill string (1) and be sunk to the bottom of the bore hole (27). The apparatus comprises a pilot control unit (B), a hydraulic engine (12), a hydraulic pump (16), and impact apparatus (21) and a drill bit (23). Drilling mud which is fed down through the drill string to flash up the cuttings drives the hydraulic engine which is of a robust construction and will withstand the abrasive drilling mud. The output shaft (15) of the engine drives the hydraulic pump which pumps high grade hydraulic fluid to the impact apparatus which is a hydraulically driven hammer rock drill of known construction. The impact piston strikes against the drill bit. The whole apparatus is rotated by means of a rotary machine placed on the ground level. Due to the pilot control unit (B) the apparatus only has to carry its own dead weight and openings and valves provide a bypass and stopping, respectively, of the drilling mud.
