Abstract: ABSTRACT OF THE DISCLOSURE           Water insoluble disperse dyes for aromatic polyester textile material are made by the reaction of an aldehyde inter-mediate derived from an .alpha.(N alkylanilino)-m-toluenesulfonamide, typified by .alpha.-(N-ethylaninino)-m-toluenesulfonamide, with a nitrile containing an active methylene group, such as malononi-trile.  This class of dyes, when appropriately dispersed, produces bright greenish-yellow dyeings on aromatic polyester fabrics with excellent substantivity, outstanding sublimation fastness, and excellent fastness to light.  The dyes are applied to polyesters, such as polyethylene terephthalate, by carrier dyeing, pressure dyeing and thermofixation methods.

In particular the invention relates to coherent elastic semi-moist food products which are stabilized against bacterial growth by the inclusion of humectants at reduced water activity.  The products include subdivided protein material bound together with a gel formed by a polysaccharide gelling agent containing monosaccharide units other than (including in addition to) glucose residues and preferably having free or esterified acidic substituent groups,   A preferred example of such a gelling agent is a mixture of xanthan and carob gums.   Quantities of gelling agent in the range 0.2 to 5% are preferred and the moisture content should be from 30 to 70%, the humectant concentration 5 to 40%, the pH from 3.5 to 7.5, and the water activity (Aw) below 0.95 or below 0.85 depending on the acidity of the product.   The invention allows for the preparation of meat-like products for animals having an elastic coherent structure with a high gel strength from the less attractive varieties or cuts of meats or offals.

Abstract: Abstract of the Disclosure The invention concerns a process for wet transfer printing and a machine for effecting this process. The machine includes a rotatable, heated cylinder around which a transfer web and a fabric web are continuously passed one on top of the other, the two webs being held together and in contact with the cylinder by means of a continuous belt which is guided around a portion of the cylinder with the two webs therebetween.  The belt is made of a water impervious material and several pressure applicator devices are pro-vided at circumferentially spaced locations around the cylinder for applying pressure, in addition to that provided by the belt, to the transfer/fabric web combination.  The webs are periodically subjected by the pressure applic-ator devices to the additional pressures when the webs pass between these devices and the cylinder.  The individual magnitudes of the additional pressures progressively increase in the direction of passage of the webs around the cylinder.  The combined effect of the pressure exerted by the belt and the additional pressures is sufficient to flatten the fabric web whereby the fabric and transfer webs are placed in intimate contact and also sufficient to form a continuous aqueous film between the two webs.

Title: Circuit arrangement for controlling the propulsion, braking and station stopping functions for a rapid transit train
Inventor: GRUNDY REED H
IPC: B61L3/00
Filed: 1976-03-30
Granted: 1979-05-01
Abstract: ABSTRACT OF THE DISCLOSURE This disclosure relates to a propulsion, braking and sta-tion stopping circuit arrangement for rapid transit trains.  In a propulsion operating mode actual velocity signal and a de-sired velocity signal are coupled to a first summing and ampli-fying circuit for producing a velocity error signal. A second summing and amplifying circuit receives the velocity error sig-nal and a multiple actual acceleration signal to produce a propulsion error signal. An absolute value and signal deter-mining circuit receives the propulsion error signal and pro-duces an up/down signal and an analog signal to drive a clock. The up/down signal and pulses from the clock are applied to the advance train line register and the propulsion train line encoder to control the propulsion effort of the train.  In a braking operating mode, the velocity error signal is combined with another multiple actual acceleration signal to provide a speed control brake error signal.  The speed control brake error signal is fed to a clamping  circuit which is enabled by a zero and down signal to allow the speed control brake error signal to pass through a timing and gating network and to the input of an output amplifier.  The output amplifier produces a brake error signal which deactivates a brake relay through a comparator and relay driver circuit and which causes the appli-cation of the braking effort through a train line wire driver. In a station stop operating mode, the actual acceleration sig-nal and a calculated deceleration signal are summed by a sum-ming network to produce a station stop brake signal which is coupled through a timing circuit to a gate.  When the calcu-lated actual deceleration is approximately ninety (90) per cent of the value of the desired acceleration signal, a comparator supplies a signal through an OR gate to the second summing and amplifying circuit to drive the propulsion effort to a coast condition.  Now when the calculated deceleration and desired acceleration signals are equal, another comparator disaables the gating circuit and enables the gate to permit the station stop brake error signal to be applied to the input of the output amplifier.  Again, the brake relay is deactivated through the comparator and relay driver circuit and a brake error signal is conveyed over the train line wire driver to apply the brakes of the train.  A flare signal removes the station stop brake error signal from the output amplifier at a predetermined distance from the stopping point to allow the train to come to a smooth stop, and a holding signal causes a preselected braking effort to be applied to the brakes un-til the train is ready to get underway.
