Title: Process for producing a product hydrocarbon having a reduced content of normal paraffins
Inventor: WARD JOHN W
IPC: C10G47/16
Filed: 1987-01-05
Granted: 1991-06-25
Abstract: PROCESS FOR PRODUCING A PRODUCT HYDROCARBON HAVING A REDUCED CONTENT OF NORMAL PARAFFINS            ABSTRACT OF THE DISCLOSURE           A waxy hydrocarbon feedstock is converted into a product hydrocarbon of reduced normal paraffin content by either dewaxing or hydrodewaxing the feedstock in the pres-ence a dewaxing or hydrodewaxing catalyst under conditions such that the normal paraffin content of the feedstock is reduced by selectively converting waxy paraffins into lower molecular weight hydrocarbons.  At least a portion of the effluent from the dewaxing or hydrodewaxing zone is then passed to a hydrocracking zone where it is contacted with a hydrocracking catalyst in the presence of hydrogen under conditions such that a further reduction in the normal par-affin content is effected.  When the desired product is a lube oil base stock, the overall conversion of components in the feed boiling above about 650° F. to components boiling at or below about 650° F. that takes place in the dewaxing or hydrodewaxing step and the hydrocracking step combined is no more than about 20 volume percent, preferably no more than about 10 volume percent.  When the desired product is a mid-dle distillate, the overall conversion of feedstock constit-uents in the dewaxing or hydrodewaxing step and the hydro-cracking step combined to components boiling below about 300° F. is no more than about 25 volume percent, preferably no more than about 15 volume percent.

Granted: 1993-03-09
Abstract: PROCESS FOR REMOVING CONTAMINANT                           ABSTRACT      Contaminant is removed from holes by etching in a gaseous plasma by first removing contaminant from the vicinity of the edges of the hole.  Next, a mask is provided in the vicinity of the edges to prevent etching by contacting with a gaseous plasma which is different from the gaseous plasma employed in the first etching step.  The holes are then etched in a gaseous plasma to remove contaminant from the interior of the holes in the vicinity of the center of the holes, whereby the mask protects the edges from being etched.

Title: Magnetic treatment of ferromagnetic materials
Inventor: DRITS VLADIMIR
IPC: H01F13/00
Filed: 1987-03-02
Granted: 1993-05-04
Abstract: ABSTRACT OF THE DISCLOSURE        A device for treatment of ferromagnetic materials comprising means for developing a magnetic field of a selected intensity, duration, and cycle, which field is passed through materials to be processed . such as cutting tools and drill bits      that have been sharpened or resharpened and other parts that have internal stresses.  The magnetic field through the material provides stress relief of the stresses from welding, forming, heating, cooling or sharpening or loading.      The treatment increases surface wear resistance, decreases the coefficient of friction on the surfaces that are so treated, and increases the strength and modulus of elasticity.  In certain types of materials, an increase in the surface concentration of such alloying metals such as wolfram, molybdenum, and tungsten, as well as oxygen and carbon is achieved.

Title: Suction sound damper
Inventor: OUTZEN SVEND E
IPC: F04B39/12
Filed: 1987-06-30
Granted: 1991-01-29
Abstract: Abstract A suction sound damper for a slide piston refrigerant compressor comprises a plastics housing (107). The latter consists of two interconnected shells (108, 109). The suction nipple (10) is of a material having a higher thermal resistance than the shell material and passes through the connecting gap of the shells and is clamped between them. The shells (108, 109) are flat and are interconnected substantially in the region of the largest cross-section of the housing. The connection of the shells takes place not only at the rim (45) but also at least at part of the inter-mediate walls (128, 138, 140, 55). The connection can be brought about by ultrasonic welding. Altogether, one obtains an economi-cal suction sound damper which meets high requirements as far as quality is concerned.          Fig. 2

Granted: 1995-09-05
Abstract: A shoe sole (1) manufactured of one or more pieces of a resilient material, such as plastics, natural or synthetic rubber, including a recess extending from below the heel and forward to the forefoot. The recess only allows the longitudinal  circumferential  rims  of  the  shoe  sole  to come into contact with the walking surface when the user of the shoe is standing on said walking surface. A shock-absorbing projection (2) is provided in the recess opposite the heel bone of the foot,  said projection not coming into contact with the walking surface at a low pressure load. At a high pressure load, such as when the user is walking or running,  the shock-absorbing projection  (2) comes into contact with the walking surface. In this manner the shocks usually affecting the heel of the shoe are moved to the heel bone as well as absorbed in the best possible  manner.  When  the  user  is  standing still  the resilience is achieved by the circumferential rim of the shoe sole absorbing all the pressure in the heel area. The optimum absorption of shocks when the user of the shoe is walking and running is achieved by the pressure in the heel area being absorbed by the projection (2) situated just below the heel bone of the foot.
