Abstract: ABSTRACT     A movable hard material  plaque intended to cooperate with a fixed plaque in the flow control device of a single control mixer valve, whose shape substantially results from a basic circle from which at least one substantially triangular portion, whose sides are substantially tangent  to the basic circle,  protrudes towards the outside.  In a preferred embodiment two such substantially tri-angular portions are provided, and a side of one of these portions substantially constitutes the continuation of a side of the other portion.   Preferably,  the sides defining the triangular portions are formed by circle arcs or by straight line segments. In a pre-ferred embodiment,  the outline of the plaque is substantially de-fined by a semicircle continued by two straight line segments con-nected to one another by a circle arc whose radius is considerably larger than the radius of said semicircle, and the maximum length of the plaque, measured between the semicircle and the circle arc, is almost equal to twice the radius of the semicircle.

Abstract: METHOD FOR MAINTAINING ZERO CALIBRATION           VALUES IN ARTICLE SORTING MACHINE     Abstract of the Disclosure A method for maintaining zero calibration values rep-resentative of average tare, or average empty cup weight, in an article sorting machine of the type employing cups to sort articles by weight comprises the steps of measuring the weight of each cup, and if the cup is carrying an article, the weight of the cup and the article, passing over an electronic scale, and determining whether the cup is carrying an article based upon the value of a weight signal provided by the electronic scale.  A running sum of the values of the weight signals for the cups determined not to be carrying articles is maintained.  A count of the number of cups determined not to be carrying articles is also maintained.  After a selected interval, the running sum is divided by the count to arrive at an updated average tare, or updated average empty cup weight.  The updated average empty cup weight is subtracted from the value of the weight signal for cups determined to be carrying articles to arrive at an article weight value which is indicative of the weight of the article alone.  The article weight value is used to classify the article into one of a plur-ality of weight breaks for sorting the article according to its weight.

Abstract: PATIENT UNDERSHEET FOR PREVENTING BED SORES     Inventor:  Nathan Mayer ABSTRACT OF THE DISCLOSURE     A patient care undersheet includes a minimum number of support points in order to keep a bedridden patient from developing decubitus ulcers.  The undersheet preferably comprises a bottom layer having a number of conically shaped bubble-like supports and a top layer comprising a non-woven fabric.  An adhesive material connects the non-woven fabric to the bubble-like supports in such a manner that under pressure the bubble-like supports under pressure do not move with respect to each other.  The bubble-like supports are air tight so that the undersheet does not collapse under the pressure of a patient's body.          The ares. OF contact of the top of the bubble-like supports to the non-woven fabric is approximately 40°0 of the total top surface of the undersheet.  A patient only has to move a very small distance before a new area of skin is supported by the undersheet.

Abstract: SMOKE AND FIRE PROTECTION SYSTEM FOR ELEVATORS A smoke and fire protection system is disclosed for elevators in a multistory building having an elevator hoistway therein, with an elevator cab having vertical movement therein. The hoistway is preferably enclosed at the top to prevent discharge of smoke therethrough. A duct is positioned in the hoistway connected to the elevator cab throughout its entire range of vertical movement and has an elongated opening extending for the full height thereof and sealed by a pair of elongated strips of flexible material along each edge of the opening meeting in sealing relation. A duct of elongated cross section and bell shaped is secured on the cab and fits through the sealing strips at the point of contact therebetween for movement with the cab along the length of the elongated opening with the sealing strips maintaining sealing relation ahead of and behind the elongated bell shaped portion. A blower connected to the duct supplies fresh air to the elevator cab and may include heating, cooling, and filtering apparatus for conditioning the air supplied therethrough. The blower supplies fresh air at a volume and pressure sufficient to ventilate the cab and effect a substantial outflow of air on opening the elevator and hoistway doors.

Abstract: MOUNTING FOR DUTY CYCLE CONTROL SWITCH FOR CEILING MOUNTED DUCTLESS HEATER            Abstract of the Disclosure A temperature sensitive duty cycling control switch is mounted to a forced air ductless gas or oil heater by a special mounting bracket.  The bracket attaches to the front of the heater in the path of the heated airflow.  The mounting device is basically a tapered conduit or duct which is held at a distance from the heater so that it does not unduly obstruct the airflow and is tapered to concentrate air gener-ated by the heater onto a plate mounted in front of the duct.  The duty cycling control switch is then mounted to this plate and responds to the temperature of the plate.  This enables the cycling of the heater burner while the fan continues to operate.

A dot rate command signal related to an actuation frequency and corresponding to the pressure of ink at the head necessary for producing an ejected drop having a desired volume is compared with the ink pressure at the head to produce a pressure control signal for varying the pressure of the ink in a variable volume fluid chamber to deliver ink to the head at the desired pressure.  The pressure control signal is one chosen by experiment as that required to produce the desired ink drop volume for the specific ink supply and ink jet printer head employed.

The structure further includes means (16, 29, 30) for processing the data bits shifted from a predetermined stage of each shift register structure to provide a keystream(44); and means (31, 32) for varying the polynomial code of at least one (10) of the shift register structures by applying to the logic elements (39) an enabling polynomial code signal that varies in accordance with the content of data bits shifted from a predetermined register stage. The polynomial code of one (12) of the shift register structures is not varied in response to the polynomial code signal. The bits that cause the polynomial code signal to be varied are not included in the keystream.
