Title: Apparatus and method for recognizing words from among continuous speech
IPC: G10L15/12
Filed: 1975-07-18
Abstract: 1522851 Recognizing words THRESHOLD TECHNOLOGY Inc 16 July 1975 [17 July 1974] 29780/75 Heading G4R Signals representing speech are fed to preprocessor circuitry containing bandpass filters which translates the speech into spectral component signals on several lines which feed feature extraction circuitry. This produces, on lines 60a signals representing features, e.g. commonly used sounds or consonents. Specific words are looked for using a logic chain U 1 -U 4  connected in series. For instance chain U can look for the word zero by looking for the feature or phonemes z-i-r-o in that order. However, preferably the units U search for common group features which contain the phonemes such as VNLC (voiced noise-like consonants) which contain r and z and FV (front vowels) which contain i. The units are set by the respective consonant or a common group feature to enable the following unit in the chain. Setting of the following unit resets the prior unit. A signal 200A indicates the possible start of the word. Line 200B carries a "1" as long as the word is correctly identified but forms a reset signal for further circuitry if an incorrect phoneme is received. Line 200C indicates completion of the word. The feature lines are sampled under the control of a clock and signals representing the presence or absence of the feature on each line are fed into a 2048 stage shift register 225. The clock also increments an 11 bit counter (2<SP>11</SP>= 2048). When an initial phoneme of a word is detected the value of the counter is stored in count store 221 associated with the appropriate one of a plurality of sequential logic circuits searching for different words. When the whole word has been detected the value of the counter is stored in count store 222. If an incorrect phoneme is detected count store 221 is cleared. The values in the count stores are compared with the counter values during the next circulation of the counter. On agreement in compare 223 the initial phoneme of the detected word is leaving memory 225 and gate 235 is called to pass the stored value to processing circuitry 70. When compare 224 produces a signal the final phoneme is leaving the memory and the gate is inhibited. The data passed to the processing circuitry is normalized. Each word may occupy 800 time slots with signals being present on selected feature lines for shorter periods (Fig. 4, not shown). These time slots are shortened to, e.g. 16 time slots each representing 50 of the previous time slots and a new matrix of "1"s and "0"s is formed a "1" existing if the corresponding 50 previous time slots contained a majority of "1"s. The normalized matrix is compared with stored values to determine whether the detected word is the required word (Fig. 3, not shown).

Title: Steering devices for an aircraft wheel mounting
Inventor: PARTRIDGE RAYMOND WILLIAM
IPC: B64C25/50
Filed: 1965-07-14
Abstract: 1,111,552. Steering aircraft groundwheels. DOWTY ROTOL Ltd. 12 July, 1966 [14 July, 1965], No. 29826/65. Addition to 879,276. Heading B7H. Steering mechanism for an aircraft wheel comprises a pinion 12 connected to the wheel mounting and operated by a rack 21 having a row of fixed teeth 23, 24, 25, 26, which engage complementary sockets in the pinion, and a pair of movable teeth 28, 27, each of which can engage a corresponding end socket, 52 and 57 respectively, and none other and which can move between limiting positions, one of even spacing with the other teeth the other in close proximity to the next fixed tooth, spring means 43 urging these teeth towards their positions of even spacing, the travel of the rack being limited, in either direction, at a position where the movable tooth moves outside the outer circumference of the pinion and into close proximity to the next tooth while the rack remains stationary. The rack 21 slides along a guide member 19 and is abutted by pistons 17 and 18 operating within cylinders 14 and 15. The guide 19 and its supporting member 20 form stops limiting the movement of the pistons. A pair of smaller diameter pistons 33 and 36 are located within bores in the pistons 17 and 18 and a bar 37 abuts piston 36 and tooth 28, passing through a central slot in the tooth 27 while a pair of bars 34, one each side of bar 37, abut piston 33 and tooth 27, passing through lateral slots in the tooth 28. Control valves are provided for supplying fluid in response to movement of the steering control to either cylinder 14 or 15 so that the pressure upon the piston therein moves the rack assembly until that piston e.g. piston 17 abuts the stop 20, in which position valves come into operation to permit free eastering, as described in Specification 879,276. Continued movement of the groundwheel in the same direction moves the rack assembly until the other piston, 18, abuts the end, 61, in which position the last fixed tooth, 23, is clear of the pinion. The socket 52 in the pinion pivots the tooth 28 to a clear position, thereby moving the piston 36 against the end 61. The ground-wheel may caster freely, the tooth 28 being prevented from falling into any but the other sockets. When it is desired to re-centre the ground wheel for positive steering, the wheel having castered to a position wherein the tooth 28 has re-entered socket 52, fluid may be admitted through a conduit 64 against the piston 36 which acts through bar 37 to pivot the tooth 28 and move the pinion until the rack and pinion are in a position for re-engagement in which position the piston 36 is at its innermost limit in the piston 18, which is then moved until the pressure acts against the whole surface of the piston 18. When the piston 18 is abutting the end 61, a seal 63 isolates the space above the piston 36. The action following a steering movement in the opposite direction is similar.

Filed: 1975-07-18
Abstract: 1510849 Printers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 July 1975 [22 July 1974] 30215/75 Heading G4H For printing grey-tone images having areas of different average densities with a printer which successively prints dot lines which extend at right angles to the paper feed direction, respective bits of an n-digit binary number specifying the density are used to select respective clock pulse trains, the pulses in these trains (with the exception of that corresponding to the most significant bit) not coinciding in time. In Fig. 4, amplitude is plotted as a function of frequency f and time t as dot density in a two-dimensional plot, each plotted value being a 4 x 8 dot matrix, e.g. E1, the printer printing each vertical line (i.e. the full length of the vertical dimension of the plot) in turn, two adjacent dot positions at a time. A clock pattern generator TMG (which may be a binary counter with decoding) produces the five trains T1-T5 of Fig. 3 repetitively, having 16, 8, 4, 2, 1 pulses respectively, the pulses of T2-T5 not coinciding in time. By means of gates, each bit of a 5-bit number representing the required density selects or not (depending on its value) a respective one of the trains T1-T5, those of the trains T2-T5 which are selected being ORed together, to give two trains and these control the two dot printing elements respectively, the connections to the elements being reversed at random intervals. The clock pattern generator TMG (see Fig. 2) is driven by clock pulses CP1 and between successive lines by auxiliary clock pulses CP2 (which may be of a much higher frequency) under control of signals EL (end of line) and NL (near line). Two auxiliary pulses CP2 (counted by counter Z2), viz. the number of pairs of dot positions per column of a plot area, e.g. E1, are supplied to TMG between successive lines, and a random number (due to variations in the interval between EL and NL) every 8 lines (counted by counter Z1), to prevent troublesome periodicity appearing in the dot pattern.
