Abstract: The entire unit containing components bolted together is designed to hold bricks, blocks, and a horizontal mobile mortar tray, all easily accessible and within reach so that a mason can place the unit where it is needed. This unit can be used in three ways; to lift one block at a time, to lift three blocks at a time, and to use just the mobile mortar tray. To lift one block or three blocks, a hydraulic system is used. Also, to make mortaring easier, a mortaring guide placed on a block will enable mortar to be placed the length of the block with a minimal amount of spillage. A level line with printed joint spacing, when stretched to the correct length, can readily and simply make the joints faster and eliminate chance of variation error.

Abstract: A word-processing system or memory typewriter has the usual keyboard, input display and printer, including a correction ribbon for removing erroneous characters from a document held in the printer; together with a spelling dictionary stored within the memory, an error indicator activated upon entry of an incorrect word, and correction information and controls also stored in memory for amending the incorrect word into a trial word which matches one stored in the above-mentioned dictionary. For greater efficiency and ease of use by the operator, if the trial word is satisfactory when displayed, pressing the usual return key on the keyboard signals the system to print that trial word in place of the incorrect word on a printed document, only the erroneous characters being replaced so as to minimize use of the correction ribbon and the print ribbon in unnecessary removal and replacement of valid characters in the incorrect word.

Abstract: A current supplying device is provided and connectable across the positive and negative terminals of a battery to supply a direct current to the positive terminal. The device includes an alternating current (AC) to direct current (DC) converter for generating a direct current from an AC power source. A pair of circuits biased to inoperative conditions are coupled to the converter and separately actuable to an operative condition to supply the direct current to one of the battery terminals. A polarity detector senses the polarity of the battery terminals and provides siganls to a plurality of switches which actuate one of the circuits to the operative condition so that the direct current is always supplied to the positive terminal of the battery. Current overload protection is also provided for protecting the polarity detector and inhibiting the operation of the switches in order to return the one circuit to the inoperative condition in the event of unsafe current flow in the one circuit.

Abstract: A portable electronic typewriter having a memory incorporating a low-cost spelling-check dictionary and including a multi-character display. The typewriter is operable in a "List" mode according to which the operator can call up display of a portion of the dictionary, sequentially in alphabetical order and one word at a time. The display consists of each stored word sharing an initial set, or "string", of n characters (termed a "template") defined by the operator via the keyboard of the typewriter. In a preferred version, when the typist becomes aware of uncertainty as to spelling, the List Mode may be initiated either before or after partial entry of the desired word. In particular, if the characters entered include an erroneous one, (the typist being alerted of this by an audible alarm, for example), initiation of the List Mode thereafter causes the string to be truncated just before the erroneous character.

Abstract: A word-processing system or memory typewriter has the usual keyboard, input display and/or printer; together with a spelling dictionary stored within the memory, and an error signal generating device activated upon entry of an incorrect word. For greater efficiency and ease of use by the operator, the memory also stores several kinds of correction information--e.g., typographical correction, transposition reversal, phonetic substitutions, etc.--suitable for amending the incorrect word to display a trial word which matches one from the above-mentioned stored dictionary, the amending occurring by depression of a special key whenever entry of an incorrect word activates the error-signal device. Statistical control of selection of the class of correction information is provided, the order of utilization of the various classes depending upon the relative extent of the operator's prior successful usage of each class of information.

Abstract: A method and apparatus for adding a low-cost spelling check dictionary feature to document preparation systems such as portable electronic typewriters, the spelling check being performed on a character-by-character basis and an error signal emitted upon the earliest determination that an input character does not conform to that of any word listed in the dictionary. Semiconductor ROM is used for storage of the dictionary listing and for program control of the spelling check. Text compression methods are utilized to permit storage of large vocabularies (about 35,000 words) while minimizing the ROM capacity required (about 3 IC's of 256K bits each).

Abstract: A low-cost spelling-check dictionary apparatus for incorportation in a portable electronic typewriter. Semiconductor ROM is used for storage of the dictionary's word listing and for program control of the spelling check. Text compression methods are utilized to permit storage of large vocabularies (about 35,000 words) while minimizing the ROM capacity required (about 3 IC's of 256K bits each). In particular, the words are alphabetically arranged in a set of three interconnected tables together with extensions of the third table in highly compressed fashion. The tables verify the spelling order of the first three character inputs, while the extensions verify the fourth and subsequent inputs, if any. The tables have a first "look-up structure" format, whereas the extensions are arranged in a different "tree structure" type of format utilizing a "Huffman code" for the characters.

Abstract: A pneumatic tube system for conducting banking transactions with a non-captive carrier traveling between a bank teller terminal in a two-tube carrier conveyor connected with a remote customer terminal with visual communication between the teller and the customer. The terminals and tube structure and their components are combined, interrelated and cooperatively arranged with simple and inexpensive construction to provide quiet and reliable operation. Prior complex carrier delivery and dispatch holding and release devices and blower operating timers and controls are eliminated. The operation of a blower located at the customer terminal, which supplies air for pressure or vacuum movement of the carrier in the two-tube system, is controlled by carrier arrival at or dispatch from either terminal. Noise emanating from air currents in the system is reduced by mufflers located at the terminals in the tube system. The carrier moves through one of the mufflers during travel.
