Abstract: 1,206,695. Strut-type suspensions. D. B. DE CARBON. 14 March, 1968 [4 April, 1967; 14 Sept., 1967; 7 Nov., 1967; 18 Nov., 1967], No. 12536/68. Heading B7D. [Also in Division F2] In a strut for a strut-type vehicle suspension, the casing of a telescopic damper 3 slides in a guide tube 2 to the bottom of which the pistonrod 5 of the damper is connected, and oil 21 contained in the guide tube 2 is conveyed upwardly for lubricating the frictionally engaging surfaces of the damper casing and guide tube by a pumping action produced by reciprocation of the strut. Air pressure induced in a chamber 20 beneath the damper 3 forces oil up a lubricating pipe 22 which is accommodated in a groove 2<SP>1</SP> formed in the tube wall and terminates adjacent an upper bearing sleeve 6 in the tube 2. A passage 26<SP>1</SP> admits some oil from the pipe 22 to an annular groove 26 in an antifriction lining 8 within the sleeve 6, and some oil falls directly down an annular space 36 to a lower bearing sleeve 7 in the tube 2. The lubricating pipe 22 may have an oval cross-section and may have a non-return ball-valve 25 near its lower end. An aperture may be formed in the pipe 22 above the level of the oil 21 to form an oil-air emulsion in the pipe. In another embodiment, Fig. 2 (not shown), the lubricating pipe runs up the outside of the guide tube and supplies oil to an annular space below the upper bearing sleeve through a groove in a lubricating sleeve (30) inserted in the guide tube below the bearing sleeve. In a further embodiment, Fig. 3 (not shown), the oil rises to the lower bearing sleeve through an annular gap between the guide tube and a tube (22) concentrically arranged therein, and is conveyed to the upper bearing sleeve by capillary action in an annular layer of felt (40). In Fig. 7 (not shown), oil is pumped up the lubricating pipe by a bellows (46) interposed between the damper and the bottom of the guide tube. Annular sealing means may be provided between the top of the guide tube and the damper to form within the tube a pneumatic spring which may communicate with load-responsive levelling means. A .pneumatic spring may alternatively be formed by an invaginated diaphragm secured to the top of the guide tube and a surrounding protective sleeve.

Abstract: 1304929 Speech synthesis INTERNATIONAL BUSINESS MACHINES CORP 17 March 1970 [19 March 1969] 12652/70 Heading H4R In a speech synthesizer a first code sequence representing a sound sequence to be synthesized is converted, in accordance with stored orthoepy rules, into a sequence of phonemes, codes of spectrum functions are determined according to stored correspondences, codes of spectrum functions corresponding to inter phoneme transitions are determined, according to stored correspondences, and the codes of spectrum functions are assembled in order and fed to a synthesizer in accordance with predetermined time duration rules. As described a total of 125 spectrum function codes is provided in the store each represented as a fifteen digit number each digit being any number from 0 to 7 so as to specify the energy density of the sound spectrum in fifteen bands over a range of 0 to 35 dB by 5 dB steps. Each phoneme is allocated a predetermined duration in time units, the first of which is alloted a spectrum function representing the influence of the preceding phoneme, and the last two of which are alloted spectrum functions representing the influence of the succeeding phoneme, with the remaining time units, or those time units which it is determined are un-influenced by preceding or succeeding time units, being alloted spectrum functions representing the phoneme. Also stored are patterns of excitation function variation of various durations and shapes, fifteen in all and particular ones of these are selected, one for each time unit of the spectrum function. The selection of the excitation function patterns, or melodic segments, may be controlled by the operator, or correlated with the phoneme. In addition each succession of spectrum function codes, representing a word has associated with it an initial fundamental frequency value for the excitation function from which the melodic segments control the variation. In a practical synthesizer a central processing unit would feed a synthesis unit with, for each word to be synthesized, 7 bits specifying the first spectrum address, 7 bits specifying the initial fundamental frequency value, 4 bits specifying the melodic segment and then further groups of alternately 7 and 4 bits specifying succeeding spectrum addresses and melodic segments for the remainder of the word. Alternatively if the sounds are unvoiced the melodic segment address is replaced by 4 bits specifying the duration of the time unit. Voiced/unvoiced indication may be provided by reserving a portion of the spectrum memory for unvoiced sounds alternatively one bit can be added to the 45 bits representative of a spectrum to indicate whether it should be voiced or unvoiced. The coded spectrum functions and excitation functions are used to drive a channel recoder synthesizer of the type described in Specifications 1,087,305 and 1,172,080.

IPC: D06M11/38
Filed: 1935-04-29
Abstract: Filaments, threads, ribbons, and fibres of organic ester of cellulose are saponified at a temperature between 25 and 75 DEG  C. by treatment with an aqueous solution of a mineral saponifying agent in the presence of an alkali metal salt of the acid of the ester, the concentration of the saponifying agent being such as would in the absence of the salt produce a pH concentration equal to that of a 0,25 to 2,0 per cent solution of caustic soda.  The amount of alkali metal salt, e.g. sodium acetate, may be from 5,0 to 15,0 per cent. It is advantageous for the initial products to have a high tenacity, e.g. of at least 2 grams per denier.  The initial materials may be subjected to shrinking or swelling.  The saponifying bath may contain swelling agents, gelatine or other albuminous substance capable of forming amino acids by decomposition by the saponifying agent. Preferably, the saponification is effected as a bath treatment applied to running threads in warp formation.  Specifications 389,823 and 428,224 are referred to.
