Title: Apparatus and method for feeding particulate material such as coal and other bulk materials
Inventor: KRAUSS KENNETH J
IPC: G01G11/08
Filed: 1986-07-18
Granted: 1990-11-06
Abstract: Apparatus and Method for Feeding Particulate Material Such as Coal and Other Bulk Materials Abstract A batch scale weighs the particulate material and delivers it periodically to a volumetric feeder through a hooper.  A computer controller responsive to a feeding rate demand signal, the length of the period during which each batch is delivered from the scale, and the speed of the volumetric feeder, provides outputs indicating the feed rate produced by the volumetric feeder and can control the speed of the feeder to obtain the demanded feed rate.  The result is that the material is fed at a feed rate in terms of units of weight per units of time, and the volumetric feeder is converted, by the addition of the batch scale and the computer controller, into a gravimetric feeder.

Abstract: ABSTRACT OF THE DISCLOSURE       A cable clamp utilizes a pair of mutually engageable and slidable tapered members.  One of the members is a sleeve member and the other is a wedge member slidable and guidable in the sleeve member.  A generally oblong shim member can be positioned between the sleeve and wedge members to engage a cable clamp therebetween so that the wedge member will slide on the shim rather than on the cable member during the clamping and unclamping actions.  The shim has an elongated slot along one side thereof which will fit over a side of the sleeve member so that the shim can be easily tilted for appropriate insertion or removal of the cable prior to insertion or following removal of the wedge member.

Abstract: ABSTRACT OF THE DISCLOSURE Cell-free or released T cell antigen receptors, immunoassays which allow the detection of the released T cell antigen receptor in cell culture supernatants, cell lysates, and biological fluids, as well as diagnostic and therapeutic compositions and methods for monitoring and treating certain diseases or disorders which elicit or involve a T cell response are described.  The released T cell antigen receptors described herein differ from the cell membrane bound antigen receptors and appear to exist in a variety of forms, some of which may be complexed with other T cell determinants such as the T3 antigen.  Despite the size heterogeneity of the released T cell antigen receptors or receptor/complexes, these may be reliably identified using anti-receptor antibodies, including, but not limited to, anti-major framework, anti-minor framework and anti-clonotypic antibodies which define particular epitopes of the released T cell receptor or receptor/complex.  The immunoassays described herein may be used to test for the presence of the released receptor or receptor/complex in biological samples and may be used to diagnose or monitor patients with disorders or diseases that elicit or involve T cell responses who exhibit elevated serum levels of the receptor or receptor/complex.  In addition, the cell free T cell antigen receptors themselves may be used diagnostically and/or therapeutically for diseases or conditions that are not easily addressed using immunoglobulins.

IPC: H01L21/28
Filed: 1987-06-17
Granted: 1991-09-17
Abstract: Abstract:       This invention is a method of manufacturing devices including a semiconductor/dielectric interface wherein at least a monolayer of the dielectric layer is in an ordered state.  Dielectric compound layers having ordered interface structure can be produced on strained semiconductor materials, e.g., by native growth.  For example, a 5 x 5 reconstruction at the interface between silicon and silicon oxide results upon oxidizing a thin layer of (111)-silicon which is on a layer of relaxed germanium-silicon.  Also, an ordered silicon oxide can be grown on a (100)-silicon surface which is atomically smooth or whose surface steps are two monolayers high. Ordered surface structure is of interest in semiconductor device technology, e.g., at the interface between silicon and passivating silicon oxide and wherever a highly defect-free interface is beneficial.

Patent CA-1311180-C (CA)
Inventor: MALONE GILBERT R
IPC: G01N33/28
Filed: 1987-08-14
Granted: 1992-12-08
Abstract: ABSTRACT OF THE DISCLOSURE A method which involves the isolation, analysis and characterization of dispersants present in motor oils is disclosed.   The method is particularly useful in connec-tion with the characterization of high molecular weight polybutenyl  succinimide dispersants present in  finished motor  oils  so  as  to provide detailed  information with respect  to  the  starting  material  reactants  needed  to synthesize such dispersants.  The method involves breaking down  complexation  present  in  the  oil  followed  by  the isolation of  the dispersant from the oil via dialysis. The isolated dispersant in the form of a dialysis residue is  then  acidified  and  passed  through  an  ion  exchange chromatographic column to adsorb acid materials away from the dispersant.   Dispersant content and  total carbonyl content can then be determined.   The dispersant is then subjected  to  saponification  with  sodium  hydroxide  to provide a hydrocarbyl sodium succinate and a polyamine. The saponified material is subjected to further dialysis to separate it from remaining oil and then further acidi-fied.   The acidification results in the formation of a corresponding succinic acid and a dialkyl ester deriva-tive.   Procedures such as GPC and VPO determinations can then be carried out.   Model reactant components can then be  prepared  and  reacted  to  determine  if  the  reaction product  obtained matches  the  original  dispersant  being analyzed.
