Title: Keyboards
IPC: H04M1/23
Filed: 1972-08-24
Abstract: 1408297 Keyboards having coded outputs WESTERN ELECTRIC CO Inc 24 Aug 1972 [30 Aug 1971] 39383/72 Heading G4H A "stroke" keyboard incorporates a switch matrix having crosspoints comprising deformable membrane switches, the crosspoints being connected in selected sequential groups to deformable membrane contacts which define the characters of the keyboard. The keyboard comprises a flexible membrane 6, Fig. 1 (not shown), and a glass or ceramic substrate (2) separated by a spacer (4); when a character such as N, Fig. 2, is stroked downwards with a pen or stylus, two contacts on membrane (6) (shown schematically as switches 35, 37, Fig. 3) are pushed in turn through respective apertures in spacer (4) to engage corresponding contacts on substrate (2). This is equivalent to the sequential closing of switches 31, 33 at cross points P1, P2 of a matrix 31 and produces signals on output lines 30, 38 and 30, 40 (the crosspoints could be directly pressure-actuated, but in practice the double-contact characters N are used). Similarly, stroking M upwardly results in signals 30, 40 and 30, 38 (i.e. P2, P1). M, N could be the same location, the signals being obtained by stroking upwardly or downwardly as required. As shown, a 4 x 4 matrix 31 is used to generate 256 characters in terms of two-signal outputs on leads 30-44; a larger matrix could be used, and/or each character could correspond to more than two membrane contacts. Also, each location could correspond to more than one character-e.g. for accessing in a time-shared computer system (Fig. 4, not shown), or for representing selected dialling numbers (Fig.5, not shown). Together with auxiliary circuitry the keyboard may replace or supplement a standard multifrequency signalling push button telephone keyboard (Fig. 6, not shown); such auxiliary circuitry may also provide automatic character keying or prevent coding errors due to, e.g. contact bounce (Fig. 7, not shown). An embodiment is also described for keying characters into an 8-bit buffer register 86, Fig. 10 in USASCII code under the control of a timing control unit 84.

Abstract: 956,725. Route setting systems. SIEMENS & HALSKE A.G. Nov. 18, 1960, No. 39837/60 Heading B7N. In a route setting system of the entrance-exit type for controlling the passage of trains, in both directions, between a track line 1 and a station line 2 via either a straight through route (points W1 reverse, points W2 normal) or a secondary route (points W1 normal, points W2 reverse), the home signal A or the departure signal B are controlled, in dependance on the direction of travel, to " line clear" for the straight through route or " line clear for reduced speed" for the secondary route by contacts of the route setting or supervisory relays associated with the points W1, W2. The control circuit includes contacts of route testing relays P1, P2 which change-over when the route is set, contacts of directional relays R1, R2 which change-over for a home route, and contacts of a route connecting relay Z1 which change-over for home routes and contacts of a similar relay Z2 which change-over for departure routes. The contacts of the relays associated with points W1, W2 which are designated (-) change-over when the associated points are switched to reverse and those designated (+) change-over when the points are normal. Assuming a straight through route, relay A1, and hence the " line clear " signal, is energized via a circuit which includes contact W11- (closed with points W1 reversed) and contact W21+ (closed with points W2 normal). Assuming a departure via the secondary route, relay B2, and hence the " line clear for reduced speed " signal, is energized via a circuit which includes contact W21- (closed with points W2 reversed) and contact W11+ (closed with points W1 normal) in parallel.

Abstract: 1326623 Information retrieval FUJI PHOTO FILM CO Ltd 27 Aug 1970 [27 Aug 1969] 41341/70 Heading G4M Apparatus for retrieving information pertaining to a selected word in an alphabetically ordered sequence thereof, the words and the corresponding information being stored, e.g. on a microfiche, includes a register for storing the identity of a stored word, the identity being defined by a code in which each of the letters of the word up to a predetermined maximum thereof is allocated a value dependent on its alphabetic position, the resulting values being concentrated to form a total value, a memory containing, in sequence, a plurality of similarly coded representative words the total value of each of which indicates the upper (or lower) limit of the total value of the words in a corresponding section of the store, the memory either also containing the address of the section of the store corresponding to each word or being associated with an indexing means which generates the address of the section of the store corresponding to each word, a display for displaying each section of the store when fed with the corresponding address, and a means for comparing the values of each representative word in turn with the total value of an identity in the register, the comparison means being arranged, when the value associated with one of the representative words becomes greater (or less) than or coincides with that of the identity, to transmit the address associated with that representative word to the display means. As described the system is applied to the retrieval of dictionary definitions. A disc, tape, core or optical store stores keywords which may be the last word on each page of the dictionary or an imaginary word between the last word on one page and the first word on the next. The letters of the words are binary coded using five bits A=00000-Z=11010 and the code stored in the register is compared with successive key words until it becomes larger (or smaller) than or equal to a keyword whereupon the appropriate page of the dictionary is accessed, the address of the page either being read from the store or being generated by a counter which is incremented on each comparison operation. The dictionary is stored on microfilm and the appropriate page is displayed. In the event that the word desired does not contain sufficient letters to allow the correct page to be found manual sequencing may be necessary, e.g., if the keywords have three letters and words beginning with "con" may be found on n pages then manual sequencing through n-1 pages is necessary to retrieve the page containing "cony". The comparison is made by the illustrated circuit, M 0 -M4 being the inputs for one letter of the keyword and K 0 -K4 those of the desired word. When the keyword input becomes greater than the desired word a carry signal is generated at FA 4  and is fed back to FA 0 . The letters of the key and desired words are fed through sequentially to provide an output signal serving to indicate that the keyword is larger than the desired word.
