Abstract: FOLDED BIT LINE MEMORY WITH ONE DECODER              PER PAIR OF SPARE ROWS            Abstract A folded bit line configured DRAM, with even and odd rows of memory cells, also includes spare even and odd rows of memory cells which can be substituted for standard rows found to have defective cells or interconnections.  Each of the decoders associated with a standard row includes provisions for being disconnected if found to be associated with a defective row.  One common spare decoder is associated with one spare even and one spare odd row of memory cells.  Each spare decoder is designed normally to be deselected for any address but to be able to assume the address of any disconnected standard row.  Disconnection of a standard decoder and substitution of a spare decoder with the appropriate inclusion of fusible links which are selectively opened by laser irradiation.  The use of one spare decoder with both an even and odd row serves to reduce the number of needed spare decoders and thus reduces overall chip size.

Abstract: ELECTROLYSIS MACHINE            ABSTRACT OF THE DISCLOSURE     An electrolysis  machine  which  utilizes  an electrically conductive probe to be physically inserted below the surface of the skin to be located next to a hair shaft within the hair follicle.  The electrolysis machine includes two completely separate circuits.  One circuit uses a direct current, while the other circuit emits a radio frequency.   The amperage of the direct current  is  controlled  to  not  exceed  a  certain pre-established value. Upon initial establishment of the circuit with the patient, or re-establishing of the circuit with the patient, surges in electrical current are prevented through the use of a circuit which slows the rise of current to the patient.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for production of a metal-coated paper such as for use in cigarette packs, having a metal coating containing a binding agent which is applied to a paper backing material by a printing process.  The coating includes particles which have a flake structure and which can be fully wetted by the binding agent, as a result of which the particles of metal are so firmly embedded into the coating as to provide sufficient abrasion resistance to permit the resulting composite paper to be used in a high-speed automatic packaging machine.  In this process for producing such a paper, a tool is pressed against and passed over the metal coating while still moist to smooth out the metal coating, whereupon the metal coating is dried.

Abstract: ABSTRACT           The circuit comprises a surface acoustic wave device.  On the substrate (32) of the surface acoustic wave device, are provided two pairs of input transducers (33, 34, 35, 36) connected, in parallel, to the input of the circuit.  The transducers (33, 34, 35, 36) initiate surface acoustic waves corresponding to the signals applied on two pairs of paths (41, 42, 43, 44) ending at two pairs of reception transducers (37, 38, 39, 40). The outputs of the output transducers of the first pair (37, 38) are connected to the two inputs of a mixer (28) whose output yields the received digital signal.  The outputs of the second pair of transducers (39, 40) are connected to the inputs of two limiters (26, 27) whose outputs are connected to the two inputs of a mixer (29) whose output yields the analog signal.  The difference in path lengths of the first pair (41, 42) introduces a delay of the order of one bit and the difference in path lengths of the second pair (43, 44) introduces a delay equal to the inverse of twice the bandwidth between the peaks of the discriminator thus constituted.

Abstract: FOUR WHEEL DRIVE VEHICLE Abstract of the Disclosure A mechanical four wheel drive tractor having a solenoid valve which is de-energized to effect engagement of drive to the front wheels in a predetermined operational mode.  Normally, the valve is controlled by an operator switch but when the engine is overloaded and exhaust gas temperature rises, a thermal sensor breaks the circuit to the solenoid valve so that four wheel drive is automatically engaged.  This action is restricted to a low gear range by a switch linked to the mechanism selecting between the low range and a high range.  Restriction to a low gear range prevents unwanted automatic four wheel drive engagement from occuring in other gear ranges without regard to vehicle speed.  Automatic engagement of four wheel drive reduces the overload on the transmission.
