Abstract: ABSTRACT     A movable stanchion for bracing freight in a transporting vehicle such as a railroad car or the like. The stanchion is supported for movement along the length of the cargo area of the car by an overhead track. A locking device carried by the stanchion cooperates with the overhead track and a floor mounted track to lock the stanchion in preselected bracing positions. The stanchion has a bracing face that extends transversely to its direction of movement and which is substantially less in the transverse direction than one-half of the width of the cargo area. The stanchion also has a device which cooperates with the floor mounted track so as to prevent pivotal movement in a transverse direction.

Abstract: ABSTRACT OF THE DISCLOSURE             A digital private automatic branch exchange provides a plurality of ports which may comprise line trunks or operator circuits, the ports being grouped with each group being controlled by an individual microprocessor circuit which performs all real time control over the ports.  Voice communication between ports is effected by time division multiplex in connection with a digital switch system forming part of a common control which is controlled by a central processing unit responsive to the microprocessors in each port group for assigning time slots to each interconnection channel.  Isolation between the central processing unit and the rest of the system is provided by a peripheral bus to which the common control units and port groups are connected, which peripheral bus is connected to the CPU bus by way of an interface circuit, permitting the system to operate with various types of central processing units without redesign of the peripheral units.

Abstract: PCM TONE SIGNAL GENERATOR Abstract of the Disclosure A digital tone signal generator supplies PCM sample sequences of various signalling tones to TDM channels in an associated switching facility to accommodate signalling requirements.  The phase of any one tone supplied to various channels is essentially different to minimize crosstalk in telephone network transmission facilities.  The tone signal generator includes an address sequencer for generating a repetitive series of addresses.  Each repetition preferably includes more addresses than channel occurrences per frame, the number of addresses corresponding to a dividend yielding other than a whole number quotient with a divisor corresponding to the number of samples in the tone sample sequence and integer submultiples of same other than 1.  A memory responsive to the addresses includes the samples of the tone sample sequence stored at address accessible locations.  The samples are stored in such order that occurrences of the addresses cause the memory to read out samples in the order of the tone sample sequence progressively with each occurrence of a given TDM channel.          - i -

Abstract: "ABSTRACT" "Method of manufacturing a colour television display tube and tube thus manufactured".              A method of manufacturing a colour televi-sion display tube in which, for providing luminescent phosphor particles on the screen, a photoconductive layer is provided with a uniform charge which may be either positive or negative. On said layer a charge pattern is formed by scanning the display window via the colour selection electrode by means of an electron beam the electrons of which penetrate through the photoconductive layer. The charge disappears in the places hit by the electron beam. The remaining charge pattern is developed by means of a suspension of charged phosphor particles. By repeating the method, patterns of red, green and blue luminescent phosphor particles can successively be pro-vided. It is also possible to scan a light-absorbing layer simultaneously or successively by means of three electron beams and to develop the thus obtained charge pattern with light-absorbing pigment.

Abstract: ABSTRACT      Bleed-fast, dyed cellulosics particularly absorbent papers have been obtained with a particular class of water-soluble, cationic dyes reacted with a water-soluble dialde-hyde, preferably glyoxal or glutaraldehyde.  An aqueous printing fluid containing the water-soluble cationic dye and the dialdehyde, upon drying, produces a water-resistant dyestuff having improved bleed fastness upon cellulosic fibers.  The water-soluble, cationic dye is one which has a functional lower alkylene amine group capable of reacting with glyoxal or glutaraldehyde to enhance the bleed fast-ness of the dyestuff on cellulosic fibres.

Each group of side-by-side casting forms is preferably supported above the bed on a carriage (214) longitudinally moveable on rollers (220), thereby permitting relative movement of adjacent end-to-end carriages to compensate for concrete contraction when pretensioned wire strands in the concrete are detensioned and for a slight recoil action when adjacent end-to-end crossties are separated by sawing. An apparatus (140, 270) for lifting side-by-side crossties in groups is also disclosed. The apparatus (270) preferably is equipped with hydraulic jacks (282) for forcibly ejecting the concrete crossties from their forms.

Abstract: ABSTRACT OF THE DISCLOSURE    Thirty telephone channels are time-division-multiplexed for transmission and reception in a PCM 30 transmission system.  The control- and switching-signals of the thirty telephone channels (e.g., dialing pulses, busy signals, dial tone signals, etc.) are converted from the form of ordinary D.C. currents to an encoded form which the time-division-multiplex system can process.  The processing of all the control- and switching-signal data is per-formed during computing time intervals of a time frame which has been subdivided into computing time intervals in real-time using a control logic which cooperates with a data storage, the control logic being comprised of programmable and permanently wired func-tional circuit stages.  The selection of a particular program from those programmed in such functional circuit stages is performed in dependence upon the significance of the control- and switching-signal information being processed.

Abstract: FLOW-THROUGH COALESCING SEPARATOR            Abstract A flow-through coalescing separator applicable to clean immiscible liquids and to dirt-carrying immiscible liquids, such as dirty oil and water mixtures. A normally retracted piston periodically backwashes and thereupon compresses the filter body in a pressure vessel so as to purge the filter body of accumulations of dirt and hydrocarbons. When the piston is thereafter being retracted by restoration of input liquid flow pressure, positive coupling of thepiston to the filter body stretches it back to its original length and thereby to the full functioning open-pore condition despite wall friction and limited rebound capability of the filter body material. The system lends itself to manually controlled operation and to automatically controlled operation, either in the continuous flow-through mode or in the more frequently interrupted retention flow-through mode. In either mode the system provides predictably-metered backwash liquid volume determined by pressure vessel capacity from its input chamber to the working face of the piston.

Abstract: ABSTRACT OF THE DISCLOSURE A metal pipe bevelling tool has a shaft with a forward end portion on which is mounted a mandrel with movable jaws engageable with the inside of a pipe end to hold the shaft coaxial with the pipe. A tool hub is rotatably supported by a rearward end portion of the shaft, the tool hub carrying cutting tools for bevelling the end of the pipe, and also having means engageable with an auxiliary power drive for rotating the tool hub. The tool hub, and consequently the whole apparatus, is enabled to be fairly small and light by a special mounting arrangement for the cutting tools. In this arrangement, the tool hub has recesses the axes of which lie in a direction extending outwardly and forwardly from the hub, and these recesses are each provided with a tool holding sleeve having an external surface fitting closely within the respective recess and defining a central cavity of square cross section for receiving the shank of a cutting tool. The tool is mounted so that its cutting por-tion extends beyond the outer end of the sleeve, and the sleeves themselves project outwardly beyond the hub so that the hub can be much smaller than the pipe to be bevelled, while the sleeves still provide adequate support for the cutting tools.
