Abstract: ABSTRACT     A cold water pour-in beverage brewer having a general-ly C-shaped body with upper and lower leg portions extending forwardly from an upright interconnecting leg portion.  The body houses an inverted L-shaped receptacle formed by an elongated shallow cold water basin from adjacent one end of which a relatively deep hot water tank depends.  The basin sets in the top of the upper leg portion and has an out-turned flange on its top edge which rests on an in-turned flange on the top opening in the body.  A cover fits the basin and rests thereon in raised relationship to provide a vent path therebetween.  The cover has a pour-in opening adjacent the front of the brewer.  The hot water tank is housed mainly within the upright leg portion.  A removable funnel is sup-ported underneath upper leg portion.  Beverage from the fun-nel falls into a beaker on a heater on the lower leg portion.          A removable baffle closes the opening between the cold water basin and the hot water tank to provide access to the interior of the hot water tank for cleaning.  The baffle has a drain opening aligned with a cold water tube extending down-wardly into the hot water tank from the baffle the drain open-ing is substantially smaller than the interior of the cold water tube.  A vent tube carried by the baffle provides vent-ing between the head space in the hot water tank and the upper portion of the basin.

Abstract: ABSTRACT                       A Tooth Bite Model A bite pattern model consisting of a base plate on which the tooth cast of the relevant part of the jaw is precisely fixed, it being possible to remove this tooth cast, however.  In order to guarantee a good seat of the tooth cast, which if necessary can be broken down into individual teeth, and to create a base plate that can be used for numerous molding processes, to which the most varied tooth dies can be fixed, and also to guarantee a mounting for the cast teeth which makes it possible to work on them, the present invention proposes a tongue-and-groove arrangement between the tooth die and the base plate.  Irregularities in the line of the groove and/or tongue are provided, for example, in the form of stops (detents) that ensure a firm seating, even of individual teeth, in the base plate.  A development of the present invention makes it possible to lock the tooth die in the base plate.

Abstract: This invention relates to method and apparatus for forming reinforced concrete walls with continuous steel reinforcements. The invention is basically an improvement on the process disclosed in Veder U.S. Patent 3.310,952. The process includes the forming of a plurlaity of concrete panels, each panel having a reinforcing cage extending to proximate the joint between the concrete panels and one or more expansible joint reinforcing cages bridging the gap between the reinforcing cages in the adjoining panels. The expensible joint reinforcing cages are carried in carrier means in the end stop pipe. Each expensible joint reinforcing cage is comprised of a vertical support bar having secured thereto a plurality of horizontally extending concrete anchor members rigidly secured to one surface of the vertical support bar. A plurality of reinforcing bar members are pivotally coupled to the vertical support bar member and an operating rod member or channel member is coupled to the opposite ends of the these reinforcing bar members and shifts them from a substantially vertical position to a substantially horizontal position after the stop pipe has been removed and the next succeeding panel excavation performed. The vertical orientation of these reinforcing bar members as well as their operating member asssures that they will be removed from the area of excavation of the next succeeding and adjacent panel section and, at the same time, by virtue of the concrete anchor members they are rigidly and securely anchored in the preceeding concrete panel element. In a preferred embodiment, the vertical bar member is a channel member and the operating rod member is a similar channel member.

Abstract: ABSTRACT OF THE DISCLOSURE              CLUTCH ENGAGEMENT CONTROL SYSTEM     A tractor power take-off drive line which includes a friction clutch (12) which is engaged by a fluid pressure operated actuator (12a) via a solenoid-operated valve (14).          The engagement of the clutch is controlled by a system which includes a pulse width modulation function for providing a series of electrical pulses to the solenoid (14a) of the valve in successive predetermined time intervals during engagement of the clutch.  Each pulse has an "on" period during which the valve connects the actuator to a source of pressurised fluid and an "off" period during which the valve connects the actuator to a dump line.  Sensors (18,19) provide signals indicative of the input and output speeds of the clutch, and a mirco processor contol circuit (25) establish for successive time intervals the ratio between the input and output speeds of the clutch and the change in this ratio by comparison with the ratio for a previous time interval.  The control circuit compares the change in input to output speed ratio with a target change in this ratio set by the system for the respective time interval to produce an error signal, and uses this error signal to set the ratio of the "on" and "off" periods of the pulse width modulation function for the next successive time interval.  The control circuit also uses the value of the input to output speed ratio to determine the target change in the input to output speed ratio for the next successive time interval so as to adjust the clutch engagement pressure to tend to reduce the error signal to zero.

Abstract: ABSTRACT OF THE DISCLOSURE          A system for recognizing the content of a communication in symbolic language and composed of plural glyphs arranged in a predetermined order, each glyph being the smallest (lowest) informational unit of the language.  The system includes a device for inputting a stream of data indicative of the plural glyphs, such as formed in a page of text.  That stream is input into a storage means.  The stored data is horizontally segmented into discrete lines of text and is then vertically segmented into individual glyphs.  Each individual glyph is assigned a unique identifier, whereby all substantially identical glyphs are represented by the same identifier.  The identifiers are arranged in a sequence corresponding to the sequence in which the glyphs appeared in the communication, thus representing glyph "words".     The system then applies decryption routines which include general cryptoyraphic techniques to the identifiers, their sequences and their interrelationships to determine the equivalent symbol of language corresponding to each identifier.  Once the symbol of language corresponding to each identifier has been determined, the machine code equivalent (i.e., code capable of being "understood" and utilized by an electronic computer) is substituted for each identifier, so as to provide a machine readable code representa-tion of the communication, e.g., page of text.

Abstract: ABSTRACT OF THE DISCLOSURE       A slide fastener slider has an arch-shaped lug projecting from the top surface of an upper wing and terminating in a rear free end spaced from the top surface of the upper wing by a predetermined gap.  A slide is slidably mounted in the upper wing and has a closure projection.  The slide is movable between an open position in which the closure projection is spaced from the free end of the lug to open the gap for allowing the pintle of a pull tab to pass therethrough, and a closed position in which the closure projection is disposed adjacent to the free end of the lug to close the gap for preventing the pintle of the pull tab from passing therethrough.  The slide is normally urged to its closed position by a spring mounted in the upper wing.  The advance of the present invention is in that the invention provides a detachable pull tab which is neat in appearance and which can maintain its proper orientation even when it is being pulled.
