Title: Sound analysis
IPC: G10L15/00
Filed: 1978-05-04
Abstract: For sound analysis, especially for speaker identification, a long-term spectrum is often formed from the recorded signal and compared to a long-term spectrum of a previously recorded signal. When the signal is, for example, received over telephone lines the transfer function thereof may distort the received signal to such an extent that identification is impossible. It is now proposed not to use the long-term spectrum for identification but rather its change, that is to say to accumulate the difference between two consecutive short-term spectra or the difference between such short-term spectrum and the long-term spectrum and to divide this accumulated value by the long-term spectrum in a Divider. Since the numerator and denominator each contain the frequency-weighting factor (aJ) of the telephone line transfer function, this factor is effectively cancelled out by virtue of the division operation performed in the Divider thereby eliminating the effect of the unknown transfer function. As a result the influence of the transfer function of the transmission path disappears almost completely.
Patent GB-987289-A (GB)
Title: Analogue to digital conversion system
IPC: H03M1/00
Filed: 1962-05-09
Abstract: 987, 289. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 9, 1962 [June 6, 1961], No. 17829/62. Heading G4H. In an analogue-to-digital converter the digitized value is converted to an alternating current and subsequently reconverted to D.C. which is fed to a comparator together with the input analogue signal. The converter is controlled by a sequence of timing pulses. When an analogue signal is to be digitized binary digital register 50 is set to digit 8. This digital value is converted to the analogue value and used to charge capacitor 22. The capacitor is next connected to the unknown analogue signal and, if this differs from the value stored, a current flows which has a direction dependent upon the sign of the difference voltage. Unit 40 increases the signal/noise ratio and gives a signal on positive or negative leads to unit 46. If the unknown signal is less than digit 8 unit 46 gives a resetting signal which removes digit 8 from the register; if the unknown is greater than 8 the digit 8 is not removed. The next timing pulse switches in digit 4, and the comparison cycle repeats. When two decades have been determined in binary form a signal is emitted on line 122. Part of the circuiting is double shielded as indicated in broken line so that the unknown analogue input is isolated from the converter. The comparison voltage is therefore converted to A.C. by unit 62 and coupled to the comparison section by transformer 66. A range selector 24 is provided prior to the capacitor 22. The difference current pulse is extracted by way of transformer 14. If the difference voltage is large, e.g. at the beginning of the conversion, signals may appear on both leads 42 and 44 due to overshoot in amplifier 38. Unit 46 will detect which of the leads was marked first and provide the appropriate output. Unit 46 may also provide an indication of the sign of the analogue input, it controlling the phase of the demodulator 72 appropriately. As no digit greater than 9 can be registered, if the first comparison indicates a digit 8 then digits 4 and 2 can be blocked.

Title: Improvements in and relating to multi-ply paper sacks or bags
IPC: B31B19/14
Filed: 1943-10-29
Abstract: 568,623. Paper sacks. ROBINSON, F. G., and PAPER SACKS, Ltd. Oct. 29, 1943, No. 17930. [Class 94 (ii)] In a multi-ply paper sack made on a tube-making machine, portions of a pasted area of a seam on a web are exposed while wet to the next web, through perforations in the unpasted seam of the first tube. The adhesion of only small spaced areas of adjacent webs prevents the cockling of the paper caused by the normal practice of pasting the whole areas of one web. The invention is applied to a machine such as described in Specification 459,377, in which a multi-ply, staggered-mouth, sack tube is formed and divided into lengths for presentation to block-bottoming or like closure means. Webs 1, 2, 3 are supplied from rolls 1a, 2a, 3a, 3 being the outermost web. Prior to folding, perforating means 4, 5 make incisions in the unpasted margins of webs 1, 2, and means, such as a bar 16 or roller cause the protruding flaps 14 to be folded back on the web, leaving holes to expose the pasted seam, A rotary arm 6 coacts with a grooved roller 11. a cutter 7 protruding through the web 1, the arm mounting 8 and roller 11 being adjustable. The peripheral speed of the cutter 7 is equal to, or slightly less than the linear velocity of the web. An alternative form of cutter 21, for the web 2, co-operates with a fixed grooved plate 18 which deflects the web to cause it to be under slight tension. Reciprocating cutters may be used in place of the rotary cutters. Specifications 443,950 and 526,676 also are referred to.

Abstract: 1,268,791. Pipe joints; valves. COMPAGNIE FRANCAISE DES PETROLES S.A. 9 April, 1969 [9 Aug., 1968], No. 18161/69. Headings F2G, F2P and F2V. A device for connecting and disconnecting a pair of ducts 1, 3 comprises a body 5 defining a conduit 15 for coupling to the duet 1, a body 6 receivable in the body 5 and defining a conduit 11 for coupling to the duct 3, and a sleeve 7 receivable by the body 5 and located between opposed surfaces of the bodies at which the conduits 15, 11 open and including a passage 13. The sleeve is connected to one of the bodies so as to be movable relative thereto between a first position in which the passage 13 is in register with the conduit 15 and a second position in which the sleeve obturates the conduit, the body 6 being positionable relative to the sleeve with the conduit 11 therein in register with the passage so that, when the sleeve is in the first position thereof, the conduits are in communication the body 5 and the sleeve being movable relative to the body 6 to remove the body 5 from the body 6. In a modification, rotation of the sleeve is effected by a lever 38, Fig. 6, attached to a collar 39 carrying pins 43 engaging in slots 44 in the sleeve 42 so that movement of the lever raises the sleeve upon rotation of the sleeve, the sleeve subsequently dropping again to bear on the member 41; alternatively, an endless screw acts on the collar. A monitoring mechanism prevents rotation of the sleeve before removal of a ring which retains the sleeve in the duct-connecting position. A cable 47 attached to the inner member 49 guides that member along the axis of the sleeve. There may be an intermediate sleeve adapted to take up two positions, one in which the passages therein allows communication between the ducts, and the other wherein such communication is prevented; in this case after the sleeve bearing in the fixed body 5 has been lifted and rotated, the ducts of the body 6 are obturated when the body 6 has been withdrawn.
