Abstract: ABSTRACT    The accuracy of well logging data transmitted from a downhole location to the surface of the earth is verified by generating the data at the downhole location, storing the data in a subsurface assembly in the well, transmitting sig-nals corresponding to the data to the surface through a first transmission system while keeping the data stored in the sub-surface assembly, and recording the signals transmitted to the surface through the first transmission system.  There-after, the subsurface assembly is transferred to the surface, and signals corresponding to the stored data are transmitted through a second transmission system from the assembly to an electronic processing system.  The signals transmitted through the second transmission system are then compared with the signals transmitted through the first system.    To increase the effective transmission rate of data from the downhole location to the surface, a first set of signals corresponding to the magnitude of a downhole condition as a function of time during a discrete time interval are gene-rated and transmitted through a first transmission system to computer means at the downhole location.  The first set of signals are analyzed in the computer to determine properties of the function selected from the group consisting of mean value, positive and negative peak values, standard deviation value, and fundamental and harmonic frequencies and ampli-tudes.  A second set of signals corresponding to the selected values are generated and transmitted to the surface through a second transmission system.

Abstract: Abstract A helical cavity resonator having a grounded shield, a hollow coil form and associated quarter wavelength wire coil.  A non-ferrous conductive slug can be adjusted to variable positions inside the hollow coil form.          Placement of the slug in a region proximate to the inside of the wire coil tunes the cavity resonator in a predominately inductive manner.  Changing the slug position in the bore so that it is proximate to the shield top and removed from the inside of the wire coil tunes the cavity resonator in a predominately capacitive manner.  By utilizing both inductive and capacitive tuning a helical cavity resonator with a wide tuning range is realized while maintaining a simple, inexpensive construction.

Abstract: ABSTRACT OF THE DISCLOSURE     A dry hard canine biscuit having visually apparent, discrete meat and/or meat by-product particles distributed substantially uniformly throughout the biscuit is obtained by blending the non-fat solids portion of a canine biscuit dough with the particles which are substantially inert with respect to the dog biscuit dough, mixing the dry-blended mixture with water and with the fat portion of the pet biscuit dough to form a dough, forming the dough into pieces, and baking and drying the formed pieces to obtain a microbiologically stable product which can be packaged without a barrier material.  Meat and/or meat by-product particle inertness is made possible by using particles having:  1) a moisture content of 35% by weight or less and, 2) a water activity which is less than the water activity of said biscuit dough.  The substantial absence of meat particle color bleed into the biscuit is principally due to the use of meat products wherein the color is formed as part of the protein matrix.  The discrete, visually apparent dehydrated meat particles enhance the palatability and visual attractiveness of the dry biscuit.

Abstract: ALARM IMMUNE PROGRAM SIGNAL            Abstract An audio program signal is converted into 12-bit PCM words and two 12-bit words are inserted into three 8-bit time slots in  a Tl line.  To avoid interference from a "yellow" alarm in which the second bit positions of all of the 8-bit time slots are pre-empted, the three least significant bits are placed in the second, sixth and tenth bit positions of the 12-bit words, which alone can occupy the second bit position of the 8-bit time slots.     A translator for generating the 12-bit words from 14-bit linear PCM words is described.  The six most significant bits of the 14-bit words address a ROM.  Stored at each address in the ROM is a table of twelve instruction words.  Each instruction word causes a selector switch to choose a bit of the output word from 1, 0 or an  input bit. Bit order of the 12-bit words is therefore controlled by the order of instruction words in the tables of the ROM.
