Title: Device for controlling a speech synthesizer
Inventor: TSCHESCHNER WALTER
IPC: G10L13/06
Filed: 1967-12-15
Abstract: 1,214,011. Speech synthesizer. ELEKTRONISCHE RECHENMASCHINEN WISSENSCHAFTLICHER INDUSTRIEBETRIEBKARL-MARX-STADT VEB. 15 Dec., 1967, No. 57135/67. Heading H4R. In' a speech synthesizer a formant filter frequency and a formant filter bandwidth are controlled by the settings of respective ring counters, and a change in the sound produced by the synthesizer is obtained by keying in the new formant parameters and causing the counters to count in the appropriate direction until the counts correspond to the new formant parameters. As shown in Fig. 5 formant characteristics are fed in to set characteristic relays in 17 either in accordance with the operation of a keyboard or according to a stored programme. The characteristic relays in 17 are of the fast to operate and slow to release type so that, for the period immediately following a new formant frequency and bandwidth being fed in, both the new characteristics and the previous characteristics are available. The stored characteristics are fed to direction seeking circuits 13 and 16, for respectively the frequency and bandwidth of the formant, where the old value and the new value are compared in a logic circuit, shown in Fig. 3, to cause a bi-stable circuit 11, Fig. 3, to be set in one state, e.g. L, if the old value is greater than the new value, and into the other state, O, when the old value is less than the new value. The state of bi-stable device causes one or other of a set of gates, 19 or 20, in the counters 14 and 15, shown in detail in Fig. 2, to be enabled to cause the counter to count either forwards or backwards, in response to clock pulses from generator 10, to the required new position. The stored characteristic is also fed from the relays 17 to inhibit the appropriate one of gates 25 to 29 so that the counter stops at the appropriate count relating to the new value of the characteristic. The selection of the required settings of counters 14 and 15 to the values corresponding to the required frequency and bandwidth of the formant filter causes the enabling of a particular gate in the co-ordinate switch 18, Fig. 5, to energize the appropriate point in a potential field 12 which comprises a conductive sheet, or an electrolytic tank having a number of output electrodes connected to the modulators of a conventional channel vocoder. The potential distribution on the electrodes depends on the precise injection point, or points, and thus controls the frequency and bandwidth of the formants synthetized by the vocoder.

Abstract: 1,121,579. Heat treating #-lactone polyester fibres. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 21 Dec., 1966, No. 57220/66. Heading B5B. A #-lactone polyester is melt extruded to form filaments, the freshly extruded molten filaments are drawn in a zone heated to a temperature above the polyester crystallization temperature to a diameter of between ¢ to about <SP>1</SP>/ 40  of the diameter at which the filaments were extruded, the filaments are then quickly cooled to a temperature below their crystallization temperature to obtain unstretched filaments, the filaments are then stretched to at least 4.5 times their original length and the starting filaments obtained as above are then given a heat treatment at a temperature of at least 120‹ C. e.g. at 190‹ C at constant length: The fibre may have been prepared from a #-lactone polyester having an intrinsic viscosity between about 2 and 4 dl/g. The polyester may be a polymer of an α, α-di-alkyl-#-propiolactone wherein the alkyl groups each have 1-4 carbon atoms, e.g. α, α-dimethyl-#-propiolactone, (pivalolactone). The starting filaments may be heated at a temperature between 125 and 200‹ C. e.g. in water under pressure or in saturated steam at a temperature between 125 and 160‹ C. or in a dry hot gas at a temperature between 150 and 200‹ C. The heat treatment may be applied for a period of time ranging from a fraction of a second at higher temperatures, such as at 195‹ C., up to several hours, e.g. ¢-2 hours or more at lower temperatures. The filaments may be heated at constant length, with limited shrinkage, or free of tension. They are preferably heated under such conditions that their residual shrinkage is not more than 5%, determined at 180‹ C. This may be effected by boiling off the filaments at constant length for ¢ hour at 100‹ C. followed by saturated steam treatment for 1 hour at 120- 130‹ C. allowing free shrinkage, or by heating free of tension in dry air for 5 minutes at 150‹ C. The heat treatment may be carried out in one or more stages, e.g. first at a temperature below 100‹ C. (preferably in saturated steam at 125-160‹ C.), and the filaments after being converted into fabric form may be given a final heat treatment at a temperature of at least 170‹ C.

IPC: G01S7/60
Filed: 1969-11-26
Abstract: 1286647 Recording apparatus SIMRAD A S 26 Nov 1969 57890/69 Heading G1J In apparatus with means for unwinding a recording strip 17 from a spool 2 and rewinding it on a spool 1 with a predetermined linear velocity, one of the spools is slipably coupled to first driving means 8 while the outermost layer of the strip 17 wound on the spool 1 is frictionally and unslipably coupled to second driving means 11, in order to adjust the linear velocity of the strip to the predetermined value while the first driving means 8 is continuously slipping. In apparatus for sonar and echo sounding systems driving torque is supplied to a shaft 5, which drives a friction wheel 8 pressed by a spring 18 against a rim of spool 1. The shaft 5 also drives two endless belts 11 frictionally engaging the roll of the strip 17 already wound on the spool 1. The belts 11 run round rollers 19, 13 and are pressed against the strip 17 by a spring acting on a frame 15 supporting the rollers 19, 13 and pivoted on the shaft 5, the friction in the pivot increasing the contact pressure. The velocity ratios are such that the wheel 8 would always drive the strip 17 faster than the belts 11, but as the wheel 8 can slip and the belts cannot the strip 17 is driven at constant speed by the belts. Alternatively the wheel 8 may engage the spool 2 at an angular velocity such as to underdrive the strip 17 which is brought to the desired velocity by the belts 11 with the wheel and slipping. The spools 1, 2 are mounted in a cartridge 3 moulded from electrically non-conductive material provided with a conductive layer on its face 3a to provide a return lead for the electrical signals to be recorded. The cartridge 3 may be inverted to reverse the functions of the spools with respect to unwinding and rewinding. The strip 17 is kept taut during recording by a brake 12, which is omitted if the friction wheel 8 is applied to the supply spool instead of to the take-up spool. In the embodiment of Fig. 4 (not shown) the shaft 5 drives through a slipping clutch, a pinion engaging a pinion on the spool 1 and the frame 15 carries a friction roller urged by the spring 16 into contact with the strip 17 on the spool 1.

Patent GB-611764-A (GB)
Abstract: 611,764. Date indicators. MOLLER, M. C. GLEERUP-. May 7, 1946, No. 13786. [Class 106 (iv)] A date indicator comprises co-axial " day," " date " and " mouth " indicators actuated by a lever through pawl and ratchet means, including a pawl pivoted on the lever and having a cam surface with which engages one end of a bell crank lever positioned in accordance with the position of the month indicator so that the pivoted pawl moves into the path of a projection on the date indicator and advances it appropriately at the end of each month. Each day a lever 21 is depressed and during part of its return up-stroke causes pawls to advance ratchet wheels 14, 16 fixed respectively to " day " and " date " drums 5, 12. The advance of the " day " ratchet 14 is restricted to one tooth by a stud on the actuating lever 21 co-operating with a slot in an arm carrying a spring pawl and a detent prevents reverse action. A spring pawl for advancing the date " drum " partly overlies a rounded upper part of a support 2 and can only engage the ratchet 16 when it slips into a groove in the support 2, thus limiting rotation to one tooth. During the month a cam 30 turns with the " date " drum and moves a pawl carrying arm against spring means, until at the end of a resolution the cam releases the arm to allow the pawl to advance the ratchet wheel 15 fixed to a " month drum 6, a detent preventing reverse action. To adjust for the variation in the length of the month, a cam 18 (see Fig. 5), turns with the " month " drum and is engaged by one end 44 of a bell-crank lever 43 whose other end 41 (see Fig. 6), engages a cam surface 51 of a pawl 48 pivoted on the actuating lever 21, contact being maintained by a spring 49. Thus upon the daily upward movement of the lever 21 the pawl 48 will clear a projection 26 on the date drum until the last day of the month when their co-operation will cause the date drum to advance a number of days as determined by the position of the cam 18 and so expose the first date of the following month. The date drum comprises 31 flaps 7, pivoted to end discs 10, 11 and enclosed by a screen 12, 54 so disposed that the flaps in contact with the screen 54 are approximately normal to the screen and so form a self-locking device to prevent reverse rotation.
