Abstract: ABSTRACT OF THE DISCLOSURE         This invention is directed to water-in-oil emulsions of water-soluble polymers and to a process for making such emulsions.  The emulsion comprises (1) a discontinuous aqueous phase containing a water--soluble polymer which aqueous phase is dispersed as colloidal size particles or droplets in (2) a continuous oil phase wherein the emulsion contains an emulsion stabilizing amount of a water-soluble salt and an emulsifying amount of a water-in-oil emulsifier, said salt added prior to polymerization to form the water--soluble cationic polymer.  The water-in-oil emulsions are characterized in that the water-soluble polymer is a cationic polymer and the water-soluble salt is a salt of a monovalent anion.           The process for preparing the water-in-oil emulsions comprises (1) forming a stable water-in-oil emulsion (monomeric precursor) containing at least one water-soluble monomer in the aqueous phase which is dispersed in a continuous oil phase, said emulsion containing a stabilizing amount of a water-soluble salt and an emulsifying amount of a water-in-oil emulsifier, and (2) subjecting the monomeric precursor to conditions sufficient to polymerize the monomer.  The method is characterized in that at least one water-soluble monomer is a cationic monomer and the water-soluble salt is a salt of a monovalent anion.           The water-in-oil emulsions of this invention are employed to supply flocculant to many substrates including, for example, sewage, cellulosic fibers and fines for retention and freeness; metal or treatment plating wastes, and coal tailings.

Abstract: Abstract Disclosed is an inclined axis windmill. The windmill has a plurality of blades generally transverse to the upstanding rotor shaft. The blades have an airfoil cross-sectional shape and are oriented with a negative angle of attack, thereby allowing the leading edge of the airfoil to turn into the wind. The windmill preferably has a tilting assembly which tilts the rotor shaft and blades at an angle dependent upon the velocity of the wind. As the wind velocity increases the rotor shaft is automatically tilted into a more nearly vertical position by the control tail. This automatic tilting of the windmill provides automatic control of the rotor speed. The rotor blades are preferably pivotally connected to the rotor shaft.

Abstract: ABSTRACT OF THE DISCLOSURE      A solar heating and cooling system is disclosed which provides substantially consistent levels of tem-perature within a preselected range in an air space of an enclosed structure.  The system includes a first store which functions as a heat source and a second store which functions as a heat sink.  A variable feed fan is used for transmitting air through the first store and into the air space when the level of the sensed temperature within the air space drops below the preselected range.  A second variable speed fan is used for transmitting air through the second store and into the air space when the level of the sensed tem-perature within the air space rises above the prese-lected range.  Both fans are used to transfer heat from the warm store to the cool store when the warm store overheats.  Energy may be purchased on an as needed basis or at off peak periods in anticipation of need.

Granted: 1987-10-06
Abstract: MUSIC DELIVERY SYSTEM A music delivery system permitting a subscriber to select from among a plurality of available music selections, particular selections that the subscriber wishes to hear at any time. The plurality of music selections are "played" at a central "jukebox" facility. They are frequency multiplexed onto one or more communication channels that are typically used to carry video information, such as a cable television channel. The video channel information is distributed to individual subscribers either via unused channels of a cable television system, by direct broadcast at commercial television frequencies, by direct satellite transmission to a subscriber, or by some other means. A subscriber uses a converter box to demultiplex and thereby select a desired musical selection for demodulation. Demodulation can take place in the subscriber's television or in some other apparatus. Music selections are selected in a similar fashion to the manner in which particular channels of a cable television system are selected for video viewing. Each music selection is on an audio sub-channel of a video channel. The music on the sub-channels is continuously played in such a way that any specific selection can be chosen at any time.

Abstract: ABSTRACT           Hardware for performing microcode branching in a central processing unit allows for two different speeds of branches which can be used by microcode and includes flexibility to optionally inhibit the extra lines which enter the pipeline on a branch.  A default branch path can be taken for a test result not yet available and can be replaced with a correct branch target during a clock pause if the test result is false.  A return address stack is provided with decoupled loading and pushing to accommodate the two branching speeds.          Microcode can specify loading the return address stack with a literal or register value to allow vectored branching and return to a desired line after a delayed call.

Title: Duplex speech transmission method and a system  therefor
Inventor: WHITE PHILIP D
IPC: H04B1/66
Filed: 1984-12-05
Granted: 1988-01-19
Abstract: ABSTRACT:           The invention relates to a duplex speech transmission method and a system therefor and has particular, but not exclusive, application to cordless telephone systems.  In known time division duplex transmission systems speech by one party is digitalised at a certain mean bit rate and then time-compressed and applied in alter-nate slots in a speech transmission channel, the remaining slots being used by the other party on the link.  The disadvantage of this known system is that when one person is not speaking then his slots on the transmission channel are left vacant.  In the method described when it is determined that one party has no valid speech to send in his time slot then the other party is able to use that time slot so that his speech can be digitised at a higher mean bit rate, thereby providing greater fidelity and avoiding vacant slots in the trans-mission channel.

Abstract: HIGHLY ENERGY EFFICIENT HEAT RECLAMATION MEANS    FOR FOOD DISPLAY CASE REFRIGERATION SYSTEMS                  ABSTRACT OF THE DISCLOSURE:     A refrigeration system for food display cases is disclosed, having a heat reclamation coil, to which hot gas discharged by the system's compressors may be diverted in accordance with the conventional practice, to provide heat energy usable for heating and/or controlling the moisture content of the interior store area.  An improvement in such heat reclamation systems is disclosed, in that the output of the heat reclaim coil is continuously sensed to determine whether it is in an all-liquid condition, or alternatively, a mixture of liquid and gas.  If the former, valving is automatically operated to bypass the liquid output from the heat reclaim coil around the system's condenser to the liquid line downstream from the condenser, so that the heat reclaim coil functions as the system's condenser in these circumstances.          If the output from the heat reclaim coil is a gas-liquid mixture, it is returned to the input side of the system's condenser to reduce the energy required for normal condenser operation.

Abstract: ABSTRACT      A fire alarm system which makes fire determination based on a novel idea which considers various changes of the physical phenomena in the surroundings caused in relation with the occurrence of a fire in terms of changes of vectors.          These changes in the physical phenomena are detected by the detecing section in the form of analog data and processed by a data sampling section as sampled data and stored in a storing section in such a manner as discriminating them by the detecting sections.  The tendencies of the changes are computed in a first computing section and the vectors representing the present or future conditions of the physical phenomena are computed from the sampled data.   The vector is compared in a comparing section with a preliminarily set data related to the fire detection and when the relation therebetween is not a predetermined one, an alarm is given through an alarming section.

Abstract: APPARATUS FOR COLLECTING AND/OR      GROWING PROTECTED BIOLOGICAL CULTURES               ABSTRACT OF THE DISCLOSURE           The coaxial annular space between a rod and a slidably received outer cylinder is divided into three serial chambers by four seals.  Two seals are spaced apart and affixed to the front of the rod.  Two seals are spaced apart and affixed to the cylinder rearwardly of the first two.  By relative forward rod movement, a specimen captur-ing zone is exposed at the desired site of a bio-logical specimen.  Thereafter, rearward rod movement reseals the capturing zone.  Further, rearward rod movement reduces the volume of a media containing chamber and thereby moves the collection zone into contact with the desired medium.  The third chamber prevents contamination of the biologically active portions of the structures during operation.  Pre-scored break lines formed in the cylinder and rod facilitate severance of unneeded portions after collection of a biological specimen and/or after transportation to a suitable laboratory facility.  Color-coded indicia are used on the rod and/or cylinder so as to facilitate proper operation.  Reusable exten-sion pieces may be attached to the cylinder and/or rod so as to adapt a standard size module to different desired end uses.
