Abstract: ABSTRACT OF THE DISCLOSURE      Foam compositions are disclosed with a synergistic blowing agent mixture of propane and butane for use as coatings and adhesives. Foams are made by pressurizing a liquid composition containing a blowing agent mixture of propane and butane and re-leasing the pressure to form the foams.  The propane and butane are contained in a liquid composition in relative amounts which together provide a synergistic foaming effectiveness upon the liquid composition.  High foam-volume ratios are achieved at relatively low pressures employing the liquid blowing agent mix-ture of propane and butane.  The method and compositions are advantageous in making paints and adhesives with polymeric components as the film-forming or adhesive solids.

Abstract: ABSTRACT There is disclosed a method and apparatus for monitoring the alertness of the driver of a vehicle which has its own power source and which travels on an unbounded path, particularly during monotonous driving conditions.  The invention continuously monitors the electric power consumption of the vehicle and when this power consumption remains substantially constant for more than a predetermined period of time, the invention sends a signal to the driver, to which he must respond with predetermined accuracy and in a predetermined period of time.  Failing this, the invention gives the operator a warning display and repeats the test, which if failed repeatedly; results in the equipment giving an alarm perceptible to those outside the vehicle, by the horn and/or flashing lights.  In addition, the invention can preserve a record of the driving conditions and test results and can provide coded access to operation of the vehicle to prevent unauthorized entry.  The invention can also provide a test of alertness which the driver must pass before actuation of the vehicle can be initiated.

Abstract: \                         ABSTRACT     In electro-erosive machining apparatus with multi-dimensional relative motion between a tool electrode and a workpiece electrode, a simple and adaptable control is pro-vided for these relative operating movements, with overall shaping-limiting control and subordinated repetitive oblique erosion cycles.    In this connection, the feed of the tool is limited, within individual oblique-erosion cycles, to achieve by repeated cycles a predetermined shaping envelope surface in the workpiece.  The processing apparatus comprises two separate coordinating function generators by means of which two operating movements at an angle to each other, are each determinable to achieve a desired operating movement of the tool relative to the workpiece, one being used for shaping-limiting control within a cycle and the other for controlling the relationship of successive cycles.  Initia-tion of the consecutive erosion cycles is effected by means of a repetition circuit under control of a shaping-limiting control as a function of convergence of an actual value to a reference value of erosion gap width.

Abstract: MAGNESIUM DIACRYLATE, POLYOL MONOACRYLATE GROUTING COMPOSITION AND METHOD FOR GROUTING JOINTS AND/OR CRACKS IN SEWER CONDUITS THEREWITH            ABSTRACT OF THE DISCLOSURE This invention is concerned with an aqueous liquid composition comprising a mixture of unsaturated monomers in-cluding (1) magnesium diacrylate,  (2) a polyol monoacrylate selected from hydroxyethyl acrylate and hydroxypropyl acrylate, and (3) a poly ethylenically unsaturated monomer copolymeriz-able with (1) and (2) to produce covalent cross-linking bonds in the copolymer besides the ionizable magnesium bonds.  The weight ratio of (3) to the sum of (1) and (2) is in the range of about 3:97 to about 5:95.  Examples of monomers that can be used as part or all of component (3) include N,N'-methylene-bis-acrylamide and ethylene glycol diacrylate. The relative proportions between the several monomers are selected to provide on polymerization a cross-linked vinyl addition polymer gel containing both covalent (non-ionic) cross-linking bonds and ionic cross-linking bonds and the relative proportions between the several components may be predetermined to render the composition suitable for applica-tion by conventional mixing packer equipment hereinafter described.  In the latter equipment, means is provided to direct a second aqueous solution or suspension containing a water-soluble free radical initiator, such as a persulfate or peroxide, separately but concurrently with the first monomer-containing solution to a common distributor head of the movable packer positioned in the sewer conduit adjacent the joint or crack to be repaired,  The monomer solution is provided with a tertiary amine which serves as a reducing agent, thereby providing a redox polymerization system so that when the two liquids mix, upon discharge from the head, a rapid polymerization to a polymer gel occurs at the ambient temperature.

Abstract: TITLE OF THE INVENTION            SOLE FOR SPORTS SHOES, IN PARTICULAR FOR USE ON HARD SURFACES, AND A DEVICE FOR FITTING A SUPPORT MEMBER INTO THE SOLE     ABSTRACT OF THE DISCLOSURE            The invention relates to a sole for sports shoes in particular for use on hard surfaces and tracks, which has or forms a heel wedge of an elastic relatively softly yielding material. The heel wedge has at least under the support surface for the heel one recess which is accessible  from the edge of the sole and which ex-tends approximately parallel to the support surface and to the tread side of the sole. Into such recess a resiliently bendable support member can be replace-ably fitted. The recess in cross-action is narrower than the support member which can be fitted therein and thus the material of the heel wedge is locally compressed in the envivronment of the recess. Thereby the apparent hardness of the sole may be increased.

Abstract: A LOCAL AREA CONTENTION NETWORK     DATA COMMUNICATION SYSTEM     ABSTRACT OF THE DISCLOSURE        This disclosure relates to a station for a data trans-mission network which is adapted to operate in a cyclic mode for contending for access to the network channel along with other stations of the network.  The three states of the cycle are the idle state, the packet-being-transmitted state and the acknowl-edgement period state.  Each station will not begin transmission until it determines that the channel is in an idle state.  Once the station has determined that the channel is idle, it will then delay for a period of time that is randomly chosen and, if the channel is still idle, will then begin transmission.  In this way, contention conflicts between stations is minimized without unduly restricting communication between stations.  Following transmission, the channel will again be quiescent a short period of time before the acknowledgement signal is transmitted from the receiver.  Each packet of data to be transmitted is of a fixed length so as to provide for synchronization between various stations contending for access to the channel.
