Abstract: 1.11.1978                       1                       PHN 8978 ABSTRACT Amplifier comprising a first and a second amplifier element.                      An amplifier comprising a first and a second amplifier element, whose outputs are connected to a load, and a difference circuit which includes an attenuator, in which the output signal of the first amplifier element is compared with the input signal, after which a resulting correction signal is applied to the second amplifier element, the two amplifier elements, as the case may be preceded by pre-amplifiers, taking the form of power amplifiers, and the second amplifier element also being provided with a substantially identical difference circuit which com-prises an attenuator, which circuit supplies a correction signal to the first amplifier element, a signal to be amplified being applied to both amplifier elements.                               As the distortion signals appear at the load as "common mode" signals, the overall distortion becomes substantially zero in the case of equal attenuation in the two auxiliary circuits.  The power amplifiers may be provided with a voltage output as well as a current output.

Abstract: ABSTRACT OF THE DISCLOSURE       There are disclosed porous and electrolyte permeable composite diaphragms for electrolysis cells comprising a chemically inert, fibrous porous matrix or substrate impregnated with a copolymer of divinylbenzene and at least one member of the group consisting of 2-vinylpyridine and 4-vinylpyridine.  A method of electrolysis of an electrolyte using the said diaphragms and an electrolysis cell containing said diaphragms are also disclosed. The ratio of divinylbenzene to vinylpyridine is 1/16 to 1/1.  The preferred substrate is asbestos paper or asbestos mat.  The composite diaphragm preferably contains 5 to 25% (by final weight) of said copolymer.  Preferably, the copolymer is directly formed on the substrate in the absence of a solvent. The composite diaphragm may also be prepared by impregnating the inert fibrous matrix with a solution of the divinylbenzene and the vinylpyridine in an organic solvent.  The solution can contain a polymerization initiator.  The organic solvent is evaporated and the dried impregnated matrix is heated in an inert atmosphere to effect polymerization.  The composite diaphragm is then washed with an organic solvent to remove unreacted monomers.   The composite diaphragms of this invention are dimensionally stable and have good resistance to mechanical abrasion.  Their dimensional stability allows for thinner diaphragms with smaller interelectrodic distances with a saving in electrical energy.

Abstract: ABSTRACT     A car repair station is disclosed having sequential way stations along a continuous track for the assemblyline  repair of railroad cars, preferably of the Hopper type.  The car passes into and under paired gantries at a second way station.  These paired gantries are positioned at each end of the car and include a vertically moveable, horizontal lifting beam which moves up and down the gantry.          The lifting beams have protruding therefrom a bell crank.          When the bell cranks fasten to the coupler pockets and additional fastening is made to other portions of the car body the car is lifted by raising of the lifting beams and rotated about a longitudinal axis which is substantially coincident with its center of gravity.  The car trucks are wheeled away through a turntable system, and the car is rotated on its side and lowered to two platforms with the gantry cranes, horizontal lifting beam, and bell cranks releasing the car.  The car is then conveyed to a subrepair station on either side of the second way station where repair to the car underbody can be accomplished.  Once repaired, the rotating procedure is reversed and the car is placed on refurbished trucks.  Upon placement to the refurbished truck, the car is conveyed to a third way station for coupler replacement, draft gear replacement, brake reconnection and safety appliance repair.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus are provided for maintaining the activity of yeast in a continuous fermentation of sugar-contain-ing mash to alcohol. In the continuous fermentation process fresh mash is continuously added and alcoholic solution contain-ing yeast is continuously drawn off. This solution is permitted to settle. At least a portion of the settled yeast is returned to the fermentation process while the non-settled or non-flocculated yeast cells and bacteria are drawn off along the alcohol-containing solution. This results in considerable lowering of the danger of infection from the bacteria as well as increase in concentration of yeast in the fermenter and shortening of the duration of time of the mash in the fermenter, thus increasing productivity. The apparatus for effecting this process comprises a fermentation vat and a yeast sedimentation container, with conduit from the fermentation vat to the sedimentation container of fermented mash with return conduit for settled yeast and a conduit our of the settling stage of the alcoholic solution containing non-settled yeast and bacteria.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed are methods of producing hardfaced plate which eliminates distortion while making weld deposits along the length of a sheet-like plate of relatively ductile and weldable material by securing the plate about a cylindrical supporting surface, then welding hardfacing material to the plate's surface which causes the plate to shrink against and be supported by the cylindrical surface which effectively maintains the plate against substantial distortion during the welding.  The plate with the welded hard-facing material is then removed from the cylindrical surface.  Pre-ferably, the composition of the hardfacing material is such as to form random cracks at a frequency of not less than about one in each three inches upon cooling from the welding temperature, and preferably of the order of about 5/8" to about 3/4".  Preferably, the cylindrical surface, which may be a portion of a drum, is rotated about a horizontal axis while welding one or more weld beads along the circumferential length of the plate and for ease of operation at the top of the plate's surface.  The methods are particularly suited for making hardfaced plate in which the plate is not over 1/2" in thickness, for example 1/4" and 3/8" thickness plate.
