Abstract: ABSTRACT OF THE DISCLOSURE           A method and machine for splining a power transmission member by rolling are disclosed as well as the resultant splined member.  An externally toothed pinion-type mandrel of the machine is rotatably mounted between a pair of elongated dies.          An unsplined member is supported by the mandrel so that sliding movement of the elongated dies from an end-to-end relationship to an overlapping relationship meshes teeth on the dies and the teeth on the mandrel with a thin-walled annular sleeve portion of the member therebetween.  The meshing of the die and mandrel teeth deforms the sleeve portion of the member radially to form the splines and also rotates the mandrel to complete the spline forming operation about the total circumference of the member.          The mandrel may be removably mounted in a manner that permits a pair of the members to be simultaneously splined by a single stroke of the elongated dies.  The mandrel and one of the dies include synchronizing teeth that are directly meshed with each other to synchronize the commencement of mandrel rotation with the commencement of die movement.  The die teeth are sized to form the splines radially in a unique progressive manner and have tooth forms that prevent slippage between the dies and the sleeve portion being splined.  Also, the teeth may form the lengths of the splines progressively to lessen the maximum tooth load and thereby increase the die life.  The splined member has relatively tough splines and an end mounting wall that is maintained flat during the spline rolling.

Abstract: ABSTRACT OF THE DISCLOSURE         The conventional brewing process for producing a malt beverage which includes the preparation of a mash, the con-version of the mash to wort, the boiling of the wort, cooling of the wort and fermentation, is substantially abbreviated, e.g. by as much as 50% by subjecting malt flour to air classification to produce a fraction having a high starch content which is used in the mash, whereby the mash conversion and wort boiling steps can be combined in a one-kettle operation to yield a fer-mentable boiled wort.  Moreover, the by-product of the air-classification is a high protein malt flour which can be used to make bread.

Abstract: DEAD END FOR LINEAR BODIES            Abstract of the Disclosure A dead end appliance for receiving and supporting a drop wire at a selected place therealong.  The appliance comprises an elongated straight-extending body having reversed loops or hooks at the opposite ends thereof disposed in planes generally parallel to the body.  One of the loops defines an appliance mounting loop and has a generally S-shaped configuration adapted to be received over a hook-like mounting member.  The other of the loops defines a line retaining loop and has a generally U-shaped configuration.          The S-shaped loop at one end of the appliance body and the U-shaped loop at the other end of the appliance body are spaced at some distance apart along the length thereof and lie in planes which are mutually perpendicular.  When the appliance is mounted to a service pole or the like by means of the S-shaped mounting loop cooperating with the hook-like mounting member, and with the drop wire properly installed, the drop wire span extends from the source end of the wire to and through the generally U-shaped line retaining loop, spirally around the body toward the S-shaped appliance mounting loop, at least once around and bridging both the S-shaped loop and the body, around the body to the end thereof immediately adjacent the S-shaped loop and thence generally downward through the S-shaped loop to the terminal end forming the drop end of the wire.

Abstract: ABSTRACT OF THE DISCLOSURE     A container having a hollow base and a lid pivotally mounted on the base can be constructed so as to utilize a carrier pivotally mounted on the lid adjacent to the rear of the lid.  With this structure when the lid is moved from a closed to an open position the rear of the carrier is elevated.  The front of the carrier is pivotally connected to the front of the base through the use of a link which accommodates movement of the carrier toward the rear of the container as the lid is opened.  In a preferred utilization of the invention the carrier is shaped so as to carry a "load" consisting of a stack of index cards in such a manner that the index cards are capable of being moved between "storage" positions in which they extend upwardly and rear-wardly of the carrier and "open" positions in which they extend upwardly toward the front of the carrier.  A plate which in effect forms a part of the link is used to automatically move those cards from an open position into a storage position when the lid is moved from an open position to a closed position.

Abstract: ABSTRACT OF THE DISCLOSURE         An electric vehicle traction motor control circuit includes a main thyristor in series with the motor armature between two supply rails.  A second thyristor is connected in series with a commutating capacitor across the main thyristor which it can turn off by diverting the motor current briefly into the commutating capacitor.  A third thyristor is connected in series with an inductor across the commutating capacitor and serves when fired, to reverse the voltage residing on the commutating capacitor following commutation.  The second thy-ristor is connected to a pulse generator which is connected to be edge-triggered by the output of a comparator comparing actual motor current with upper and lower current limits set by a driver operable control.  The comparator also brings an oscillator into operation which provides additional trigger inputs to the pulse generator if the latter fails to be edge-triggered by the comparator output.     .

Abstract: 6196    INVENTOR: HANSPETER K?PFER CAN         INVENTION: METHOD AND APPARATUS FOR MEASURING THE             DISTANCE BETWEEN A PRIMARY STATION AND A SECONDARY STATION                       ABSTRACT OF THE DISCLOSURE            A method and apparatus for measuring the distance between a primary station and a secondary sta-tion, each having an antenna for transmitting and receiving continuous wave signals, modulated by a measuring signal, the distance being determined at the primary station as a magnitude proportional to the quo-tient of the phase difference between the measuring signals of the transmitted and the received signals and the measuring signal frequency. The primary station transmits a continuous wave signal modulated by a measuring signal which in turn can be frequency modulated by the measuring signal frequency. At the secondary station this modulated continuous wave signal is addi-tionally modulated by a marking signal and reflected to the primary station as the receiving signal. At the primary station there is obtained from the filtered mixed product from the signal reflected by the secondary station and a local oscillator signal of the primary station a useful signal which is freed of the continuous wave frequency and the measuring signal frequency. There is obtained from the useful signal by amplitude demodulation an evaluation signal freed from the marking signal fre-quency.  The evaluation signal which is dependent upon the phase difference between the measuring signals of the transmitted and received signals is employed in a regula-tion circuit for a change of the mean measuring signal frequency of the measuring signal of the transmitted signal such that the mean phase difference between the measuring signals of the transmitted signals and the reflected signals assumes a predetermined value at its steady-state condition.

Abstract: A tamper-resistant enclosure for electrical equipment is disclosed. The enclosure includes a housing having generally upstanding and planar side walls which define a top opening.  The top opening is closed by a generally horizontal and planar roof which is coextensive and congruent with the opening.  Selected walls of the housing have formed at their upper edges a C-shaped structure, the open part of the C housing outwardly. The roof is formed to have a C-shaped structure around its periphery, the open part of the C facing inwardly.  Facilities mount the roof to the housing so that the lower leg of the C on the roof is intermediate the legs of the C on the walls.  Moreover, the upper leg of the C on the walls is intermediate the legs of the C on the roof.  In this way, a labyrinth from the exterior of the enclosure to the interior is formed.  Water entry through the labyrinth into the enclosure is prevented thereby, as is the insertion of wires or the like.  The labyrinth, however, permits the flow of air through the enclosure around the enclosure's periphery, permitting the electrical equipment therewithin to be ventilated while remaining dry.
