Filed: 1990-07-19
Abstract: DIAMOND COMPACTS FOR ROCK DRILLING AND MACHINING                ABSTRACT OF THE DISCLOSURE     There is provided a method for making diamond and CBN compacts which comprises positioning a catalyst metal disc and a barrier disc intermediate a diamond or CBN mass and a carbide mass.  The catalyst metal disc is adjacent to the diamond or CBN layer and the barrier disc is intermediate said catalyst disc and the carbide mass.  In order to prevent unregulated flow of metal bond from said carbide mass to the diamond layer and to prevent depletion of metal bond from the carbide near the carbide/diamond interface, the barrier disc has a surface area virtually identical to that of the carbide mass.   Such arrangement of materials is subjected to temperature and pressure conditions within the diamond stable region but below the melting point of the barrier disc.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and an apparatus for the sterilization of refuse, in particular hospital refuse, is described, according to which plastic containers filled with the refuse are first introduced into a lock chamber in which a preparatory conveyor belt is arranged and thereafter the entire charge of the lock chamber is transferred to a sterilization chamber in which a main conveyor belt is arranged.  The sterilization chamber is then hermetically sealed and injection needles are stuck into the respective containers to inject water and/or disinfectant into the interior of the respective plastic containers.  The refuse is then treated with microwave energy and subsequently the charge in the sterilization chamber discharged via the discharge opening.  With the method and the apparatus according to the invention it is always ensured that the refuse in the interior of the plastic containers is impregnated in adequate manner with water or a disinfectant, this being done before or during the microwave irradiation.

Title: Method of decoding bar code symbols from partial scans
Inventor: PAVLIDIS THEODOSIOS
IPC: G06K7/10
Filed: 1990-07-30
Abstract: Abstract of the Disclosure A method for decoding bar code symbols in which a bar code reader and associated components scan a bar code symbol produce a representation  of  the  symbol,  and  attempt  to  decode  that representation in order to produce a character message.  The method consists of the steps of storing a first representation of the bar code symbol corresponding to a first scan path through a first portion of said symbol smaller than the entire symbol, and storing a second representation of the bar code symbol corresponding to a second scan path through the symbol.  The method then processes said representations in the event a successful decode has not taken place by utilizing the signal from a first scan with the signal from a subsequent scan to determine whether the information from successive scans can be concatenated to form a combined signal.          The process is repeated with different subsequent scans until successful decoding of the combined signal.

Abstract: In a sampling rate converter which converts a sampling frequency of digital signals sampled at a first sampling frequency into a second sampling frequency, output clocks corresponding to the second sampling frequency are counted in a cyclic fashion from an initial value to a maximum value based on periodicity of the first and second sampling frequencies. Coefficient addresses are generated in accordance to the resulting count value and a coefficient correction value in accordance with a number of counts of the maximum value and the periodicity of the first and second sampling frequencies, the number of the maximum value which is a number of times of counting to the maximum value. The sampling frequency of digital signals sampled at the first sampling frequency is thus converted into the second sampling frequency with a simple construction of counting to the maximum value in accordance to the periodicity of the sampling frequencies.
