Patent CA-2001593-A1 (CA)
Title: Ionization system
Inventor: BREIDEGAM ALBERT C
IPC: H05F3/04
Filed: 1989-10-26
Abstract: ABSTRACT An area ionization system which includes a first set of positive emitters and a second set of negative emitters for providing a supply of positive and negative ions to a work area. A control circuit or computerized control system simultaneously provides high voltage to the positive emitters and to the negative emitters.  This "steady state DC" system has been found to be superior to previous systems which provide alternating current or pulsed direct current to emitters.  The steady, balanced supply of positive and negative ions allows faster charge decay rates within the work area as well as reduced foreign material contamination.  The system also distributes power to the emitters throughout the work area via low voltage lines.  The low voltage is stepped up in the emitter arrays in order to supply 8-12 kilovolts to the emitters.  The lower voltage requirements as compared to alternating current and pulse direct current systems reduces production of harmful ozone, and the low voltage distribution system decreases conflicts with electrical code requirements.  This system also allows the environmental history for products manufactured in the work area to be documented, including the following parameters: ionization, temperature, humidity, air flow, and ozone data.

Title: Scan converter for a high definition television system
Inventor: LUCAS KEITH
IPC: H04N7/015
Filed: 1990-04-25
Abstract: SCAN CONVERTER FOR A            HIGH DEFINITION TELEVISION SYSTEM            ABSTRACT OF THE DISCLOSURE      A high definition B-MAC television signal transmission system comprises a scan converter and a signal pre-processor for accepting signals in various high definition formats. In particular, an 1125 line or 1050 line to 525 line scan converter is required due to the prepon-derance of at least 1125 line and to some extent 1050 line 60 Hertz field rate format high definition television studio equipment. The scan converter includes circuitry for converting from horizontal to vertical scan format via first and second field stores. A phase shift transversal filter spatially shifts every sample of each field by 1/4 line. In alternate fields, the direction of spatial shifting reverses.          For an interlace output, alternate line samples are discarded or for a sequential scan output, all samples are used. The output of the trans-versal filter is scan converted to reassume a horizontal scan format.          Three field stores are used to buffer the input and output field rates such that one field of samples is dropped every one thousand fields in order to convert from a 60 Hz field rate to 59.94 Hz. At the same time, the coefficients of the transversal filter are reversed for the next field of samples after the dropped field. The scan converter provides a digital 525 line 1:2 or, in another embodiment with two field rate converter circuits, a 1:1 format output. According to B-MAC signal processing, an interlace 525 line output is provided to a pre-processor which additionally may accept a 525 line analog RGB     input. Also, the pre-processor may generate its own test pattern signals.
Patent CA-2016104-A1 (CA)
IPC: A23P1/08
Filed: 1990-05-04
Abstract: A method for forming a moving, continuous bed which is composed of granular and/or pulverulent flowable material and which is of constant thickness provides an improved uniformity of the bed by collecting material from a first moving bed so as to form a buffer stock, and by subsequently delivering material from the stock in a regular fashion so as to form a second moving bed which is continuous.     An apparatus for carrying out this method comprises a belt capable of being passed through by said material. The material can be moved with the belt over a guide plate situated beneath the belt.  In order to prevent  too  little  material  being  present  locally  during  brief interruptions in the supply of the flowable material and in order to prevent the material being compressed and pulverized in the event of an excessively large supply, a buffer is provided for the material,  the discharge opening of which buffer is situated near and above the guide plate. The buffer has an overflow. The material is thus fed via the buffer onto the belt. Provided the buffer remains filled, it is capable of compensating automatically for fluctuations in the material supply.

Title: Method for removal of dimethyl ether and methanol from c4 hydrocarbon streams
Inventor: SMITH LAWRENCE A JR
IPC: C07C7/04
Filed: 1991-04-16
Abstract: ABSTRACT OF THE DISCLOSURE    A process  for removing dimethyl ether  (DME)  and methanol impurities from C4 hydrocarbon stream without substantial loss of C4  hydrocarbons  by  fractionating  a  C4  hydrocarbon  stream containing DME and methanol at low levels, e.g., less than 5 wt.% to produce an overhead of about 20 to 40 volume % of the C4 stream, condensing the overhead, contacting the condensed overhead with about 1 to 5 volumes of water, thereby removing a portion of the DME and methanol from the C4 stream, returning substantially all of the C4 stream, except the small amount solubilized in the water, to the fractionation and flashing the solubilized DME and hydrocarbons from the water.  The fractionation and extraction are preferably carried out at elevated pressures,  e.g.,  200 to 300 psig to avoid refrigeration of the overhead condensation.   The flashing of the DME and hydrocarbons is carried out by reducing the  pressure  on  the  water,  e.g.  atmospheric  pressure  at  a temperature in the range of 20°C to 50°C, leaving methanol in the water.    The  methanol  can  be  removed  by  distillation  or  by contacting  the  methanol  containing water stream with  a  large volume  of  a  C4  stream whereby  a portion  of the methanol  is extracted in the C4 stream.   The methanol depleted stream can recycle to contact the condensed overhead from the fractionation thereby establishing a closed circuit water wash/methanol recovery system.          \CRL.PAT\986.APP

Title: Overflow control system

Filed: 1991-05-10
Abstract: A protective system for use with central air conditioning systems for large buildings,  particularly multi-storied buildings having circulating cold water as the heat transfer medium, wherein failure of the condensate drain for an evaporate drain trough can lead to the accumulation of undue quantities of liquid condensate, with consequent flooding and water damage, uses a water accumulation detector to detect the accumulation  of  water  in  each  individual evaporator  drain trough.  Operation of the detector circuit energizes a warning alarm circuit and also a disabling switch in a heat transfer circulation control circuit, so that further condensation onto the evaporator is precluded, and consequent flooding is prevented.   The circulation control circuit generally requires manual resetting, and is usually connected in the circuit of the local air circulation fan associated with the affected evaporator.
