Title: Laminated sheets for microwave heating
Inventor: OCHOCKI MICHAEL J
IPC: H05B6/64
Filed: 1989-01-18
Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE      A coated laminate is described comprising a micro-wave transparent supporting sheet or substrate such as paper, paperboard or plastic upon which is printed a susceptor lamina comprising a cured dispersion of an organic printing ink vehicle matrix in which is uniformly suspended at least two kinds of dispersed particles, one of which is an electrically conductive microwave interactive carbon particle and the other of which is an electrically nonconductive suspended mineral attenuator particle for dissipating, spreading and modulating the energy received by the conductive particles.  Of the two kinds of suspended particles, only the carbon particles interact with microwave energy directly.  Both types of suspended particles remain dispersed in the ink vehicle until printed and cured.  The printed lamina can include areas of solid coverage surrounded by peripheral areas of decreased coverage which include small open areas, i.e. unprinted openings, with larger size unprinted openings provided proceeding toward the periphery of the susceptor lamina.

Granted: 1993-08-24
Abstract: SCROLL TYPE COMPRESSOR          ABSTRACT OF THE DISCLOSURE     An oil separating mechanism of a hermetically sealed  scroll  type  compressor  in which  an  inner chamber of a housing is kept at discharge pressure is disclosed.  The compressor includes a drive shaft supported by a plain bearing in an inner block mem-ber.   The drive shaft is operatively linked to an orbiting scroll  which orbits  within  a  stationary scroll.   The drive shaft  includes  an axial bore extending from an open end and termination within the inner block member.   A radial bore is provided near the terminal end of the axial bore and links the axial bore to a discharge chamber of the com-pressor.  A helical groove is formed on the exterior surface of the supported portion of the drive shaft. The  helical  groove  is  linked  to  the  axial  bore through a radial hole formed through the supported portion of the drive shaft.   The open end of the axial bore is isolatedly linked to the outlet of the compressor such that refrigerant gas flowing from the  discharge  chamber  to  the  outlet  must  flow through the radial bores and axial bore of the drive shaft.  Therefore, lubricating oil mixed within the refrigerant gas as a mist is retained at the radial bores and does not flow out of the compressor with the refrigerant gas,  increasing the efficiency of the external cooling circuit.

Title: Fume hood sash sensing apparatus
Inventor: SHARP GORDON P
IPC: B08B15/02
Filed: 1989-05-19
Granted: 1992-07-28
Abstract: ABSTRACT     This invention provides an apparatus for sensing the extent to which the opening of a fume hood is uncovered by the hood sashes, and is particularly adapted for use with hoods having sashes which are moved horizontally.  Radiation from a radiation emitter, such as an optical or a magnetic emitter, are sensed by corresponding detectors.  For some embodiments of the invention, there is relative movement between the emitters and detectors as the sashes are moved to cover or uncover the opening, the movement between the emitter and the detector being such that the amount of radiation detected by the detectors is proportional to the uncovered portion of the opening.  The relative movement may be accomplished by, for example, having the detectors fixed and having the emitters mounted to the sashes or by having the detectors mounted to some sashes and the emitters mounted to other sashes.  A unique magnetic emitter is also provided with enhanced flux throw.  The enhanced flux throw is required with various embodiments of the invention where there may be substantial spacing between the magnetic emitter and detector.  Embodiments are also disclosed for practicing the invention with a fume hood having sashes which are adapted to be opened both vertically and horizontally.

Abstract: ABSTRACT A device for extracting a fishhook from a fish caught comprises a tubular housing with a sliding plunger housed therein that is fastened to a clamping hook extending beyond the front end of the housing so that when a retractor handle and fixed handle are squeezed together the clamping hook is retracted into the housing whereby it engages any article extending laterally across two receiving slots and thus clamps the article therein. The device grips the fishhook and locks it in the receiving slots so that rotation relative to the device is prevented. With the fishhook firmly grasped, the device allows the fishhook to be easily and safely manipulated in order to free it from the hooked fish. When a large fishhook or the like is held by the device, the device has the additional ability to serve as a gaff for safely handling dead or live fish.

Abstract: Disclosed herein is an apparatus and process for conducting ligand receptor assays. The apparatus comprises a first member which is a membrane or a filter to which is bound a receptor for the ligand or which is capable of extracting cells carrying the ligand from a fluid sample. The apparatus further comprises a second member which is composed of absorbent material which acts when in contact with the first member to induce flow through the first member when a fluid sample is added to it. The apparatus is used to conduct assays by applying a sample to the upper surface of the first member to bind ligand in the sample by means of receptor fixed to the first member or, in certain cases, by extracting cellular material which has ligand associated with it. Addition of the sample is typically followed by addition of labeled antibody against the antigen being assayed followed by a washing step to remove unbound labeled receptor. The presence of labeled antibody on the first member after washing is indicative of the presence of the antigen in the sample being assayed. In a preferred embodiment of the invention, the ligand is an antigen and the receptor is an antibody.

Abstract: This invention relates to an improvement in the production of low sheet gloss coated papers which comprises using as the synthetic polymer latex binder for the aqueous coating composition employed to coat the papers, a carboxylated latex which substantially swells during the preparation of the aqueous coating composition and subsequently shrinks during the drying of the coated paper, whereby a microscopic surface roughness is obtained to yield a low sheet gloss coated paper while retaining high ink gloss without detrimental effect on ink gloss, or the printing characteristics of the coated paper. Carboxylated latexes and their methods of preparation are generally taught in the art. The carboxylation is introduced by utilizing as one of the comonomers in the preparation of the latex a vinyl acid, such as acrylic acid, methacrylic acid, itaconic acid, fumaric acid, and maleic acid. The carboxylated latexes suitable for use in this invention are those which contain at least 6 parts of a vinyl acid monomer per 100 parts of total monomers. Using these carboxylated latexes as the binder for the aqueous coating composition employed to coat papers produces low sheet gloss coated papers to be prepared without the use of large pigment particles and/or specialized supercalendering techniques.
