Abstract: TITLE         Electrostatic Printing Process ABSTRACT     An electrostatic printing process is disclosed wherein a printing roll is formed by forming a latent magnetic image in a magnetic imaging member, decorating the latent magnetic image with a non-conductive mag-netic toner to form a toner image, transferring the toner image to a conductive member and temporarily fix-ing the toner image to the conductive member.  The toner image on the conductive member is electrostatically charged, while the charge is dissipated from the remain-ing area of the conductive member.  The charged image of magnetic toner is decorated with an electrostatic toner comprising a colorant and a binder resin to form an electrostatic image which is transferred to a substrate.          Pattern change is accomplished by washing off the fused toner from the conductive print roll and forming a new fused toner image on it.

Abstract: ABSTRACT     A tool for trimming coaxial cable comprises a cable-holding member and a cutter-holding member. Sections of the cable-holding member and cutter-holding member are matable for movement relative to each other and they are initially secured together so that stop surfaces of these members are spaced from one another based on the amount of trimming that must be done to trim a cable to a precise electrical length. The end of the cable is secured in the cable-holding member with the end to be trimmed disposed against a cutter member secured to the cutter-holding member. The matable sections are unsecured, the cutter-holding member is rotated relative to the cable-holding member so that the cutter member trims the cable end until the stop surfaces engage.

In accordance with the present invention, substantially all the water is filtered off from the pulp mixture, an air flow is produced through the filtered pulp cake by means of a pressure difference, the resisting effect of the pulp cake on the flow of air is measured, and the pulp cake is weighed, whereafter the properties of the pulp are calculated on the basis of the measurements, from mathematical models developed for this purpose The apparatus developed for carrying out the method according to the invention has a vessel equipped with a stirrer for the specimen, a device for measuring the temperature of the specimen, means for directing the specimen onto the wire and for removing the water through the wire by means of a pressure difference, a device for measuring the pressure dif-ference or through-flow produced across the wire and the pulp layer on the wire, and devices for registering the obtained measurements and for the output of the properties of the pulp. For directing a batch of a predetermined volume from the vessel into the measuring  vessel placed against the wire, this determin-ation apparatus has a specific portioning device, and the device has been fitted not to register the pressure difference or through-flow produced across the wire and the pulp layer on the wire, until substantially all the water has been removed from the pulp layer filtered onto the wire.  In addition, this apparatus has means for removing the pulp layer from the wire and a device for weighing the pulp layer.

Abstract: ABSTRACT          Satisfactory bonding of refractory aggregate is obtained by providing the aggregate with at least 5.0% by weight of free CaO of minus 200 mesh (Tyler Standard Sieve) particle size, adding a small amount of a lithium compound to the aggregate and heating to a temperature of about 450°C. The modulus of rupture at room temperature of a brick made from dead burnt dolomite aggregate containing a fine fraction providing the finely divided CaO and the lithium compound additive and fired to 450°C is well above 400 psi and may be substantially equivalent to that of a brick made of the same aggregate without the lithium compound additive and fired to 1200°C. The invention comprises the method of increasing the low temperature bonding strength of refractory aggregates, the unfired mixtures of the refractory aggregate containing the requisite CaO and the lithium compound with or without temporary liquid or solid binding agents, and the fired products made therefrom.
