Abstract: The presence of Heat Pump systems has been with us for decades. The science of ENERGY MANAGEMENT and today's environmental awareness prompted us to device a new HEAT PUMP system especially tailored to the DOMESTIC HOT WATER market. "Simplicity" is the key feature of this system! It embodies a small compressor, a tiny circulator, a heat exchanger, and an evaporator. A portion of the evaporator is wrapped around the compressor thereby extracting heat from the compressor, while the heat exchanger transfers the heat to the circulating water. A Fuzzy Logic control is used to optimize the system.

Title: Raised zone retroreflective cube corner article and method of manufacture
Inventor: SMITH KENNETH L
IPC: G02B5/124
Filed: 1994-10-20
Abstract: A cube corner article and method of manufacturing the article from a series of unitary substrates. The method of manufacture comprises the first step of providing an initial non-unitary cube corner element array comprising a plurality of geometric structures including cube corner elements (212, 218). Then, a replica of the cube corner element array is produced as a substrate suitable for forming retroreflective surfaces. Portions of the replica substrate material are removed. The removal of these portions forms at least one cavity (206) bounded by side walls in the replica at a depth at least that of the cube corner elements. The replica is replicated to produce an additional directly machinable substrate suitable for forming retroreflective surfaces. The substrate comprises at least one raised section (208) having sidewalls at a height at least that of the cube corner elements. At least one raised section is directly machined to form a zone comprising a plurality of geometric structures including cube corner elements bounded by at least two sets of parallel grooves.
Patent CA-2172028-A1 (CA)
Title: Flotation of oil-agglomerated coal for ash and pyrite removal-simultaneous grinding and agglomeration
Inventor: TRASS OLEV
IPC: B03D1/006
Filed: 1996-03-18
Abstract: Oil agglomeration is an excellent technique for the beneficiation of fine coal. For separation of the spherical agglomerates by screening, a high level of oil must be used, however. When the subsequent separation is done by flotation, this disadvantage is eliminated. Better pyrite removal is also possible. In this application, such a fine coal beneficiation process, also called hydrophobic flocculation-flotation (HFF), is described. It features low non-polar oil consumption, intensive mechanical energy input, and smaller agglomerates or looser flocs. This process can be simplified by grinding the coal in water with small amounts of oil added. The excess grinding energy is then used for agglomerating the coal. The exemplified Prince coal from Nova Scotia contained 13.3% ash and 3.3% total sulfur, 1.4% pyritic. After four stages of flotation, ash and pyrite removal were 93% and 66% respectively, with 87% combustibles recovery. The parameters affecting the HFF process, such as particle size, dosage of non-polar oil, pH value of the slurry and duration of agitation, were investigated. Simultaneous grinding and agglomeration (SGA) utilizing the Szego Mill is also disclosed at the very low oil levels used. The intensive agitation/preconditioning step prior to flotation was eliminated. When the other parameters established from the sequential process were used with the SGA process, virtually identical beneficiation results were obtained, but with slightly lower combustibles recovery. With the SGA process, significant equipment simplification and energy savings are possible.

Title: Tandem refrigeration system
Inventor: RADERMACHER K REINHARD H
IPC: F25D17/06
Filed: 1994-11-14
Abstract: A refrigeration system for providing cooling to two or more compartments utilizing respective first (2) and second (60) evaporators. During the initial operation of a cooling cycle, the refrigerant is utilized for cooling the fresh food compartment (8) which is to be maintained at a higher temperature than the freezer compartment (4). After cooling has been achieved in the fresh food compartment (8), the refrigerant in the system has reached a state suitable for cooling of the freezer compartment (4), and the fan (12) for the freezer compartment (4) is turned on while the fan (14) in the fresh food compartment (8) is turned off. A defrosting cycle can also be accomplished with the fresh food fan (14) operating, and with the freezer evaporator fan (12) and compressor (18) off. As the refrigerant evaporates in the fresh food evaporator (6) during defrosting, a thermosiphon effect results in an exchange of refrigerant between the evaporators such that defrosting is accomplished without requiring a defrost heater.

Title: Mounting of protectors in connector blocks
Inventor: FIGUEIREDO ANTONIO ALBINO
IPC: H01R4/24
Filed: 1996-05-07
Abstract: A mounting arrangement between connector modules of a double-sided modular connecting block and polarity sensitive current and voltage limiting circuit protection devices. Connector modules having multiple pairs of insulation displacement connecting (IDC) terminals are insertable into a mounting bracket to form the double-sided connecting block. Exclusionary posts are selectively molded into a front and rear side of the connector modules and correspond to each pair of terminals. The posts on the front of a connector module align and mate with a cavity included on a front-mounted current and voltage limiting protection device. Similarly posts molded in a different location on the rear side of the connector module align and mate with a cavity included in a rear-mounted protection module. The corresponding posts and cavities create an exclusionary key and slot interface which prevents circuit protection devices of improper polarity from being inserted within the wrong side of a connector module. The exclusionary mounting scheme ensures against erroneous installation of circuit protection devices which can disrupt communications and provide inadequate circuit protection.

Title: Blank detector for cassette tape player
Inventor: HIRSCHENBERGER FRANK M
IPC: G11B15/087
Filed: 1994-11-14
Abstract: Digital signal processing (DSP) employing a differential mean calculation automatically distinguishes sections of blank tape from program material (such as music or voice) on cassette tapes. Blank tape produces a negligible differential mean value while program material produces substantial differential mean values. Thus, each differential mean is compared to a threshold so that a cassette player can be commanded to fast forward through a blank section of tape. A music envelope detector insures that low amplitude music signals are not detected as blank.
