Title: Speech processor
IPC: G10L21/00
Filed: 1971-12-16
Abstract: 1356645 Analysis synthesis systems STANDARD TELEPHONES & CABLES Ltd 16 Dec 1971 58426/71 Heading H4R A speech processor for changing the formant frequency resonances of a speech signal, e.g. to make "helium" speech more intelligible or in the production of compressed speech for talking books for the blind, comprises a self adaptive filter 1 connected in a negative feed-forward configuration and with the input speech as both the filter input and target signal so that the formant resonances are substantially removed from the filter output signal. The residual signal is fed to a second adaptive filter 2 connected in a positive feedback configuration and with the multipliers on the taps of the filter connected to be adjusted in the same manner as those of the filter 1, so that formant frequencies are restored. The sampling frequencies of the two filters are arranged to be different so that the formant frequencies are shifted in the ratio of the two sampling frequencies. In addition the residual signal output from filter I is resampled, in 3, at the rate of the sampling frequency for the filter 2. In order to prevent the resampling of the residual signal missing important sample values a circuit, Fig. 4 (not shown) is used which incorporates a store (42) so that the outgoing sample of the resampler is equal to the largest input sample since the previous output sample. In the case of the application of the invention to talking books for the blind, where the frequencies of the speech are compressed so that they will be correct when replayed at higher speed, the excitation frequency, or pitch frequency, present in the residual signal, requires to be lowered in the same proportion as the filter sampling frequency. In the apparatus of Fig. 6 the residual signal, from the output of the filter system of Fig. 1, is fed to a detector 60 to derive larynx pulses which are used to transfer the contents of counter 61, counting pulses of the sampling frequency F 1 , used in the adaptive filter 1 of Fig. 1, to the register 62 and subsequently to reset counter 61 to zero so that the count in register 62 is always the number of sampling pulses of frequency F1 between the last two preceeding excitation, or larynx pulses. The count stored in register 62 is used, by counter 63 to control the generation of excitation pulses, to feed to transversal filter 2 of Fig. 1, so that the number of sampling pulses F2 occurring between successive excitation pulses at the output is the same as the number of sampling pulses F1 occurring between successive excitation pulses on the input. The adaptive filters are preferably transversal filters, the self adaptive filter being described with respect to Fig. 2 (not shown).

Patent GB-687163-A (GB)
Abstract: 687,163. Calculating-apparatus; cash registers. NILSSON, R. S. June 15, 1950 [June 17, 1949], No. 14967/50. Class 106 (i). Item-indicating drums mounted on a stepwise movable setting carriage of a calculating- machine or cash register have the digits distributed both axially and circumferentially of their peripheries, and are successively rotated and/or displaced axially each to display the set digit. In Fig. 1 the indicating drum 44, with digits 6-0 and 1-5 marked at upper and lower levels around its periphery, is secured to the upper end of a spindle 43, and a pinion 45 at the lower end of the spindle is engaged by long teeth 49 on an actuating slide 48 for rotationally adjusting the drum whilst permitting it to be lifted by its spindle 43 when the lower level is to be brought into register with a sight opening 56. For lifting the drum from its normal lower position shown, a lever arm 22 is shaped to be engaged and depressed by the stems of keys 1-5 (but not those of keys 6-9), and raises a connected lever arm 24 with a nose 27 engaging under the spindle 43 of the drum. The key stems also depress a differentially-stepped arm 20 which rocks a lever 14 counterclockwise, a finger 18 on the lever engaging behind a lug 50 on the slide 48, so drawing the slide forward into a differentially set position against the action of a return-spring 51 and rotationally adjusting the spindle 43 and drum 44. Accurate adjustment of the slide 48 is ensured by a stop-bar 35 which is brought forward into contact with the lug 50 to arrest it in exact position. The bar 35 is pivoted to the upper ends of links 29, 30, and an intermediate bar 28 on the links has slots whose forward edges are differentially inclined. Lugs, as 1a, on the keys stems engage these forward edges and cam the bar 28 forwardly and with it the stop-bar 35 into a differentially adjusted position. The machine has a single row of keys 1-9 only, and the several indicator drums 44 on their spindles 43 and with their actuating slide 48 are mounted side-by-side on a carriage 47 which is traversed step-wise laterally of the key mechanism for adjusting the drums in turn. After each drum is adjusted, the teeth 49 of its actuating slide 48 enter into engagement with the end of a stationary bar 54, and the pinion 45 engages over or under the bar, in order to retain the drum adjustment. In an alternative key mechanism, Figs. 5-10 (not shown), the keys are arranged in three columns; there are two bars as 28, and other modifications in detail, but the action is the same.

Title: Control of aquatic pests and flora utilizing fluorochemical surface films
IPC: A01M7/00
Filed: 1979-09-19
Abstract: The instant invention relates for example to techniques for the control of mosquitoes by the use of a fluorochemical agent composition which forms a durable, rapidly spreading water- insoluble surface film. The fluorochemical agent has a density greater than water, a solubility of less than 0.01% in water, a spreading pressure of preferably >50 dynes/cm at <10 mg/m<2> of water surface and is applied with a diluent to form a highly mobile film under field conditions. Optionally, a biocidal agent, such as an insecticide, algaecide, molluscicide, herbicide, or mixtures thereof, can be present in the fluorochemical/diluent composition. Useful fluorochemicals for use herein are those of the formula (Rf)nTmZr, wherein Rf is a perfluorinated aliphatic group, T is a connecting group or covalent bond, and Z is a neutral or polar group; n is 1 or 2, m is 0 or 1 and r is 1 or 2. The film is especially effective under adverse environmental conditions.
