Abstract: ABSTRACT     A bag filling apparatus includes a hopper for receiving raw material.  The hopper feeds the material through an opening to a conveyor belt for transporting the material to a bagging head.  The bagging head includes a gate having two positions for selectively diverting the material to one of a first and a second outlet ports.  Underneath the bagging head is a receiving scale having a first pan and a second pan, each adapted to hold a bag for receiving the material, and a movable counterweight.          The scale is constructed to move between two positions:  a first position wherein the first pan is adjacent the first outlet port and the counterweight is adjacent the second pan and a second position wherein the second pan is adjacent the second outlet port and the counterweight is adjacent the first pan.  The movement of the receiving scale between the two positions occurs automatically when the sandbag reaches a preselected weight.  An actuator mechanism is responsive to the first and second positions to operate the gate so that material is selectively diverted to the outlet port which has a pan adjacent thereto.

IPC: D21D5/24
Filed: 1990-07-24
Abstract: An apparatus (10) is illustrated in the invention for removing coarse particles, such as sand, metal chips, etc., from a liquid, whereby the apparatus is in the first place aimed at separating coarser particles from the so called reject, which is obtained fromthe cleaning apparatuses for fiber suspensions and thus enabling a particular reutilization of the reject with its eventually remaining fiber material. The apparatus comprises a hydrocyclone (15) installed in a cylinder (20), in which the reject thereof flows out, whereby the entraining heavier particles settle and are gathered to the bottom of the cylinder (20) for discharge. The liquid rising in the cylinder flows through an overflow outlet (25) to a separate side chamber (30) open to the atmosphere, in which chamber further settling takes place. An inwardly extending pipe (40) is arranged to extend in the reject nozzle (22) of the cyclone (15). The vacuum therein extends through the inwards extending pipe, which protrudes into the side chamber (30), wherefrom liquid is redrawn to the cyclone. When desired several side chambers can be combined in series one after another for further intensification of the cleaning process.

Patent CA-2067583-A1 (CA)
Inventor: HSUNG JEAN-CHEUI
IPC: A61B5/364
Filed: 1992-04-29
Abstract: An arrhythmia detector includes a delta modulator which digitizes the ECG signal and produces a serial digital signal that represents the input ECG signal.  A microprocessor classifies the signal as having no slope, positive slope, or negative slope.  A finite state machine model in the microprocessor uses the positive slope, negative slope, or no slope information to determine the number of times an isoelectric line segment is present in the ECG signal.  By accumulating the line-counts or number of line segments over a two-second period, a determination can be made whether the ECG signal has been in isoelectric line less than a threshold.  For two out of three 2 second periods, if the percentage of isoelectric time is less than the ventricular fibrillation threshold then a ventricular fibrillation signal can be generated.  For ventricular tachycardia verses supraventricular tachycardia discrimination, a second threshold which relates to the average heart rate observed in a linear formula LC(TH) = b - a*(rate)/30 can be used.  If the isoelectric line-count is less than the LC(TH), then VT is declared.          The regression coefficient a and b can be found by measuring the line-count and rate pairs in 2 second periods during normal sinus rhythm in periodic basis, for example, 10 data pairs every hour. The delta modulator uses a comparator which receives the ECG signal and a tracking signal to output a series of binary digits.   A digital-to-analog converter generates the tracking signal.

Title: Window cleaning device
Inventor: MALLORY GEORGE T
IPC: A47L1/06
Filed: 1993-02-05
Abstract: A window cleaning device of the type having a handle, a head attached to the handle and a sponge mounted in a longitudinal channel in the head of the washer is provided.   A  net-like  web  envelops  the  sponge.    The cleaning device includes an improved stiffener having an elongate body provided with a pair of shoulders extending along the body on both sides thereof.   A plurality of protrusions are integrally formed with and extend outwardly from the shoulders on both sides of the elongate body.  The stiffener has a pair of flanges one located at each end of the elongate body for locating the body in the channel and preventing movement  of  the  body  in  the channel.   The protrusions act to compress multiple portions of the sponge between the ends of protrusions and the channel walls which creates a plurality of highly compressed areas at these points adjacent less compressed areas between the highly compressed areas into which excess sponge can flow.  The action  of  the  protrusions  to  grip  the  sponge  on  the interior thereof provides a firm anchor so that the sponge cannot be removed except by dislodging the stiffener from the channel.  At the highly compressed areas portions of the sponge are forced through the perforations in the web thereby creating a locking effect between the sponge and web,  similar  to  a peg  through a  hole,  which provides increased gripping strength.   The stiffener is injected moulded from plastic.

Filed: 1991-08-08
Abstract: A Natural Language Pro-cessing System utilizes a symbol parsing layer (5) and an intelligent word parsing layer (5) to produce a syntactically or pragmatically cor-rect output.  A plurality of polysem-ic symbol sequences are input through a keyboard with semantic, syntactic, or pragmatic segments in-cluding agent, action and patient segments, for example.  One poly-semic sequence is input from each of the three segments of the key-board (1).  A symbol parsing device, then parses each symbols in each polysemic symbol sequence to access a previously stored word, morpheme, or phrase.  The accessed word, morpheme, or phrase (50) corresponds to the input polysemic symbol sequence and further corresponds to one of the designated agent, action or patient segments.  Each accessed word, mor-pheme, or phrase further accesses corresponding and previously stored grammatical and semantic information.  An intelligent word parsing layer (5) subsequently applies each of the plurality or words morphemes, or phrases to a predetermined hierarchy of rules based upon the accessed grammatical and semantic information.  The intelligent word parsing device subsequently parses the received plurality of accessed words, morphemes, or phrases into a syntactically or pragmatically correct output.
