Abstract: TANK SUPPORT FOR A TANK TRUCK   Abstract of the Disclosure A tank truck having a cylindrical tank resiliently supported on a bed frame of rectangular con-figuration and disposed above the main frame of the truck with the tank being disposed partially within the horizon-tal plane of the bed frame and having the bed frame resiliently supported on the main frame of the truck.  A pair of saddle-shaped plates conforming to the outside of the cylindrical tank are secured thereto, one close to each end of the tank, and a pair of upper tank hold down brackets are secured to each saddle plate and in turn are resiliently bolted to corresponding lower tank hold down brackets which are rigidly secured to the bed frame.  The brackets secured to the bed frame are in turn bolted to corresponding brackets on the main truck frame with resilient members placed between the bed frame and the truck frame to absorb shock.  The resilient couplings not only absorb shock, but permit slight cushioning movement between the tank, bed frame and main frame during normal operating conditions on the roadway.

Title: Thermal recording apparatus
Inventor: ANNO GOUSUKE
IPC: G01D15/10

Granted: 1985-03-05
Abstract: ABSTRACT   The thermal recording apparatus of the present invention includes a plu-rality of thermal resistive elements placed in a line, a plurality of drive circuits connected to the thermal resistive elements to drive the thermal resistive elements and a plurality of latch circuits connected to the drive circuits to supply recording signals in order to the drive circuits. A first memory receives and stores incoming recording signals formed by a series of 1 and 0 signals. These recording signals are supplied to the latch circuits. A second memory stores previously received record-ing signals which are output from the first memory. A comparator then compares the incoming recording signals with the previously received recording signals after the first memory supplies the incoming recording signals to the latch circuits. The comparator generates modified recording signals. The modified recording signals include 0 signals which are generated when 1 signals in the incoming recording sig-nals follow 1 signals in the previously received recording signals. These modified recording signals are supplied to the latch circuits after the incoming recording sig-nals are supplied to the drive circuits. Thus, if successive 1 signals occur in the same bits of the recording signals, the latch circuits and drive circuits do not receive successive 1 signals so the thermal resistive elements are not continuously driven. By using such a modified recording signal to drive the thermal resistive elements for part of the time period, burn out of the thermal resistive elements can be prevented.

Abstract: ABSTRACT         A multichannel data link switching control arrange-ment for synchronizing the substitution of one data channel for another without causing the insertion or deletion of data bits from the data transmitted over the communication path that is coupled to the channels.  The switching control arrangement monitors the relative timing between the data on a channel to be replaced and the data on the replacement channel.  Precisely controlled delay circuitry delays the data on the channel rela-tive to the other until the data signals on the two channels are within ? a quarter bit of each other, at which time the channel substitution is effected.         The arrangement includes 2 pair of control switch units each of which may be selectively controlled to couple either the active channel or the replacement channel to an out-put communication link.  Each switch control unit contains an input multiplexer and an output switch, the operations of which are controlled by a data timing monitoring apparatus or control unit.  The outputs of the two switch control units are coupled to signal combining and splitting circuitry the output of which may be phase compared with the data being coupled through either switch unit.  A controllable data delay unit is coupled to one channel at the input to the dual switch control unit configuration and serves to selectively delay one channel with respect to the other as the data signals on both are applied to respective switch control units until the data stress on the two channels are synchronized.  At that time, a control signal is applied to the two switch control units to effect a simulta-neous switching of the output switches in each unit, whereby channel substitution is effected.  The delay action of the delay unit remains in the replacement channel, except that no further incrementing of the delay is carried out.

Abstract: ABSTRACT OF THE DISCLOSURE         The synthesis-gas plant is operated in a number of successive operating periods such that during the first operating period an excess of fresh water is supplied to the synthesis gas plant and the waste water from the resulting mixture is separated in a condenser and supplied to a storage container.  During the subsequent operating periods, the waste water stored in the container is used as the feed water for the synthesis gas plant and the waste water obtained on each occasion is stored in the container with increasing deuterium concentration.  The waste water obtained during the last operating period and having the highest deuterium concentration is used to feed a plant for producing heavy water.         This process, when used in a synthesis gas plant for producing hydrogen, can be used to obtain deuterium-enriched water as a feedstock for a heavy-water plant without expensive additional energy-consuming devices.

Abstract: (Case No. 7057) ABSTRACT OF THE DISCLOSURE    A "snow brake" control system in which application of the snow brake pressure during release of a normal brake application is withheld for a duration sufficient to assure movement of the vehicle brake apparatus from a brake applica-tion position to a release position, to thereby cause automatic slack adjuster action to take place.  In one embodiment, opera-tion of a piloted pneumatic valve is delayed by restricting the exhaust of pressure from a volume reservoir via a choke to thereby momentarily withhold the connection of "snow brake" control pressure to one inlet of a double check valve that is subject at its opposite inlet to normal brake control pressure.          The double check valve is effective to connect the predominant one of the pressures at its opposite inlets to a relay valve to produce brake pressure.  In a second embodiment, the double check valve is eliminated and the pilot pneumatic valve con-trols the connection of either "snow brake" or normal brake control pressure to the relay valve.
