Abstract: "ICE CRUSHER FOR REFRIGERATOR"               ABSTRACT OF  THE DISCLOSURE         Apparatus for delivering ice from an ice body maker to an ice  delivery area selectively in the form of ice bodies or as crushed ice.  The ice crusher is mounted in a housing and includes first and second crusher arms mounted to a rotat-able shaft therein.  A stop is provided for preventing rotation of the second crusher arm while permitting the first crusher arm to continue rotation with the shaft.  The relative movement between the crusher arms effects a crushing of the ice bodies so as to permit the ice to then be delivered to the delivery area in the form of crushed ice.  When the stop is positioned so as to permit rotation of both the first and second crusher arms with the shaft, the ice bodies are delivered intact thereby to the delivery area.  The stop is arranged to prevent rotation of the second crusher arm in either direction when disposed to prevent movement of the second crusher arm with the shaft.          The stop may be pivotally mounted to the housing and the control for selectively positioning the stop may be provided within the housing.  The stop may be disposed adjacent the outlet portion of the housing to provide guiding of the ice from the crusher arms to the outlet portion.

Abstract: Abstract of the Disclosure A machine-readable record or label includes alternating areas of different reflectivity providing a binary coded data record.  The record is made by selecting the widths of the areas such that an increase in the relative widths of any two consecutive areas of different characteristics represents a binary "1" and a decrease in the relative widths of any two consecutive areas represents a binary "0".  Thus, each area in the part of the code is used in the establishment of the values of two different binary bits.  A method of and a system for reading or interpreting the record or label includes a pair of light reader controlled registers in which are alternately stored the widths of consecutive areas.  A comparator coupled to the registers determines whether each newly stored width is greater than or less than the width of the previously stored area.  In accordance with this determination, the comparator stores a "1" or a "0" in a shift register, the contents of which are transferred out as each complete character is received.

Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE              A process for depositing a microporous electron-emissive cathode coating material by spray means is depicted.  The process com-prises preheating the cathode assembly and spray means by enclosing the assembly and spray means in a cathode assembly spray chamber having a laiminar flow of gas therein and stabilizing their temperature at a predetermined elevated value.  The cathode assembly is sprayed with a first coat of the material to a predetermined final thickness.  The material is fast dried by holding the cathode assembly in an enclosure having a laminar flow of gas at an elevated temperature. A second coat of the material is then sprayed on to a predetermined final overall thickness.  Due to the preheating and fast drying according to the inven-tion, the coating material so deposited is uniformly dense and the coating surface is smooth and microporous to provide enhanced emissivity and life and enhanced resistance to poisoning by contaminants.

Abstract: Abstract Disclosed is a method for the transmission of data in a synchronous data network, wherein the data is transmitted in the form of groups in envelopes composed of control bits and data bits and wherein data channels assigned to data terminal devices can be connected to the data network via data connection devices.  Each data channel is assigned at least one data bit of at least one envelope, and the control bits of the envelopes define frames for the mutual assignment of the data channels and the data bits.  Due to utilisation of the envelopes for the transmission of data in accordance with a t.d.m. process elaborate synchronising devices are not required to divide the data into the individual data channels.  The control bits of the envelopes are used as a frame characterisation for a channel division without any disturbance to their original function.  As only unstructured data can be transmitted in the individual data channels, the process is particularly suitable for the multiple exploitation of dedicated connections in the data network.  The envelopes are transmitted in the same way as envelopes whose data bits are assigned to only one single data channel.

Abstract: Canada F-2811(BBC) HEATER FOR SLIDING SEAL STRUCTURE     ABSTRACT OF THE DISCLOSURE          A seal assembly for sealing the opening between the outer periphery of a movable shaft and an opening in the wall of a housing which permits entry of the movable shaft into the interior of the housing.  The housing is filled with a fluid under positive pressure and the seal assembly includes a pliable annular seal which surrounds the shaft and slidably engages the outer surface of the shaft to permit relative movement between the pliable an-nular seal and the shaft.  A heat conductive ring supports the pliable annular seal and presses the seal against the housing and fixes the seal against the interior of the opening in the housing.  An electrically energizable heater is connected to the heat conductive ring at a location sically removed from the pliable annular seal and in ther-mal conduction relation with respect to the seal for heating the seal to prevent the seal from leaking under low temper-ature conditions which would make the seal ineffective in the absence of the thermal energy applied to the seal by the heater.  A second seal ring is disposed on the heat conductive ring and concentric with the opening in said housing.  The second seal ring is a static compressed seal and is heated by heat produced by the heater and conducted thereto by the heat conductive ring.  The annular seal and the second seal ring are coaxial with one another and each is disposed in a common plane.

Abstract: CHAIR AND SEAT-BACK UNIT THEREFOR     Abstract of the Disclosure A seat-back unit for a chair utilizes pre-flexed sheets of sinuous spring wire material connected to relatively rigid side support members which afford flexibility, but provide a frame for the unit. The two L-shaped side support members are held apart by a rigid cross stretcher member positioned in the seat portion, near the back. The seat-back unit is connected to a chair frame at only four points in a "cradling" arrangement, by means of a pair of hooks extending back from the tops of the relatively rigid members, received in slots of the chair frame, and by bolted connections of the relatively rigid members at the front of the seat portion to the chair frame. The seat-back unit, and particularly the relatively rigid frame members, are put into a pre-stressed condition as the seat portion is connected to the chair frame. Covering material, which may be removable, is positioned over the seat-back unit. A simple chair frame structure is preferably used, with an X-shaped bracing configuration at the bottom and four upright legs. This may be accomplished with two tubular members, each formed into a front and a rear leg, and an angled portion of a brace, with the portions connected together centrally.

Abstract: ABSTRACT OF THE DISCLOSURE           A safety lock system for vertically stacked slideably retained storage elements, such as file drawers.  The system comprises one or more locking bars vertically slideably retained in alignment in a vertical support guide channel.  Two or more cam elements are pivotally secured on a respective fixed pivot axis to the support guide channel adjacent an opposed end of each of the locking bars.  Each of the cam elements have a cam portion retained in planar alignment with the lock-ing bars and an activating arm portion for rotating the cam portion about the fixed pivot axis.  A displaceable space is provided below each cam element portion defined between one of the locking bar opposed ends and the cam portion.  An engaging member is secured to one or more of the storage elements.  The engaging member engages and displaces the activating arm portion of an associated cam element by predetermined displacement of a storage element having the engaging member to cause rotation of the associated cam portion to slidingly displace the locking bars thereabove through the displaceable space in immovable contact with their associated cam elements and arrest sliding displacement of the locking bars therebelow to maintain them in immovable contact with their associated cam elements to thereby immobilize all other cam elements against rotational displacement and thereby prevent slideable displacement of all other of the storage elements having an engaging member.
