Abstract: 259,739. Flinn, H. V. Sept. 19, 1925. Counters with reducing gear. - In epicyclic toothed or friction wheel or rack and pinion gearing for use in mileometers and other counters, gear-wheels C, G, F, A are arranged on a shaft B, which may carry a pointer H, the wheel C being stationary, the wheels G, F loose on the shaft and secured together, and the wheel A fixed to the shaft. A driving-member L carries planet pinions K<1>, K which gear respectively with the wheels C, G and the wheels F, A and may be loose on the same pin. The teeth numbers in the wheels are so arranged that, considering the train C, K<1>, G with C fixed, the wheel G would rotate slowly in one direction relatively to the planet carrier and considering the train F, K, A with the wheel F stationary, the wheel A would rotate slowly in the opposite direction relatively to the planet carrier. The combination effects a very great reduction. Additional trains may be added further to modify the reduction obtainable. The wheels C, G, F, A may be replaced by racks, in which case one rolling pinion may be secured to its spindle, which carries a knob for convenience in turning, the second pinion being loose on the spindle.

Abstract: 853,079. Cathode-ray tubes. GENERAL ELECTRIC CO. Ltd. July 20, 1959 [July 22, 1958 ; Oct. 29, 1958], Nos. 23462/58 and 34702/58. Class 39(1). A device for use in displaying characters has a sealed evacuated envelope 1, Fig. 1, containing a fluorescent screen 3, an electron gun 2 and two or more electrically conducting characters 4. insulated from each other and arranged consecutively along and within the cross-section of the beam, the characters being individually connected to conductors To T 1  . . . T 8 , T 9 , the device being operated so that any selected one of the characters can be caused to cast its shadow on the screen by a suitable change in the potential applied to that character. The characters may be formed of steel wire as shown in Fig. 3 and are mounted together on insulating supports as a matrix 4. Instead of flooding the whole screen as in Fig. 1, the gun may flood only a part of the screen area and deflecting means are provided to control the path of the beam between the characters and the screen whereby the position on the screen of the area illuminated by the beam and on which the shadow of the selected character falls can be changed. In this way by using afterglow phosphor and fast seaming two or more characters can be displayed together. The characters may increase in scale in proportion to the divergence or convergence of the beam so that wherever portions of separate characters correspond they overlie each other along the path of the electrons thereby minimising the total shadow area cast on the screen by non- active characters. In operation the characters are maintained at a potential a few volts positive with respect to the final anode 5, and the potential of a character to be displayed is made considerably negative with respect to this anode.

Abstract: 1435949 Electric selective signalling TEXAS INSTRUMENTS Inc and J ST CLAIR KILBY 18 May 1973 [18 May 1972] 23806/73 Heading G4H A pocket paging unit for receiving alphanumeric messages and displaying them in printed form comprises: a radio receiver, decoder means for detecting an address code, a printer, and means for enabling the printer when a desired address code has been received and energizing the printer in response to a message. In a central station, a keyboard is used to enter into a shift register, a "beginning-of-message" character, a two-character subscriber address, a multi-character message, and an "end-ofmessage" character, all in ASCII code. Detection of the "end-of-message" character at the keyboard output causes a format generator to cause the shift register to shift until the "beginning-of-message" character is detected at its output. The format generator provides to a radio transmitter a message containing an 8-bit subscriber code (consisting of 4 bits from each character of the subscriber address) two 5-bit space codes, five 5-bit column codes (constituting a 5 x 5 matrix decomposition of the first character of the message proper in the shift register, derived by a matrix character generator) two 5-bit space codes, and so on for the other message characters, a 4-bit blank being provided between successive codes, until the "end-of-message" character is detected at the output of the shift register. In a paging unit, the subscriber code is compared in an EXCL-OR gate with a hard-wired code supplied from a shift register into which it had been inserted in response to the end of the previous message. In the case of agreement, the column codes of the message characters are passed via the shift register (converting each in turn to parallel form) into a register which controls a column of thermal print elements (transistors) past which a paper tape is advanced, one column at a time, in response to each 4-bit blank (see above). The print head bearing the print elements is on the inside of a hinged lid of the paging unit. The paper is fed from a chamber (into which it is loaded in accordion-folded form) by a roller pressing the paper against the head, a hub (relative to which the roller can rotate in one sense only) being rotated by an arm actuated by a solenoid and returned by a spring. As a modification, the matrix character generator could be in the paging units rather than the central station. The message printed can specify name, address, telephone number and nature of needs of patient/customer, and urgency of call.
