Title: Radio frequency signal defect suppressor
IPC: H04N5/94
Filed: 1962-07-10
Abstract: 1,017,078. Television. MINNESTA MINING & MANUFACTURING CO. July 10, 1962 [July 10, 1961], No. 26516/62. Heading H4F. Defects in the modulated radio-frequency signal derived from a television magnetic taperecorder are detected by a sensor circuit 10, which responds to actuate a trigger circuit 19 when the carrier falls below a level preset by potentiometer 14, and employed to operate a switch 20 which substitutes for a radio-frequency signal applied directly to the switch over a first circuit 22 a signal obtained via a second circuit 23 where it is delayed for the duration of one scanning line. The invention relies for its effectiveness in the similarity in the signals in adjacent lines. Reference is also made to the use of delays corresponding to 2 or 3 lines, one field and one frame. In the arrangement described employing a delay of one line duration (63À5 microseconds for the U.S.A. television standards), the delay is obtained by an ultrasonic system 26 using a quartz medium together with an adjustable vernier delay 25. A further delay 21 common to the two circuits compensates for delay in the sensor circuit. In a modification, Fig. 2 (not shown), a phase comparitor is employed to compare the undelayed and delayed signals via the first and second circuit and to control an automatic phase convertor in the second circuit. This arrangement is stated to compensate for variations imparted by variations in tape speed and frequency instability. In a further arrangement, Fig. 3 (not shown), the substitution of one signal for the other takes place in the blanking interval at the end of the line when a defect is detected and is maintained for the duration of a full line. For this purpose the switch is connected so as normally to transmit the delayed signal and in the event of a defect substitutes the undelayed signal. The operation of the switch is triggered by-line sync. pulses.-

Title: Improvements in and relating to timing means for controlling or operating a series of variable indicating, signalling, warning or supervisory devices
IPC: G08G1/085
Filed: 1939-09-25
Abstract: 532,910. Time-alarm signals ; electric switches. SMITH, S. J., and TELEPHONE MANUFACTURING CO., Ltd. Sept. 25, 1939, No. 26580. [Class 118 (ii)] [Also in Group XXXVII] A timing-device for controlling or operating, according to a pre-set programme, one or more indicating or warning devices is characterized by the use of a signal-controlling member moving relatively slowly and bearing mechanical or electrical circuit-controlling elements, and further members, moving relatively rapidly, each serving to control the duration or repetition of signals transmitted over one of the circuits. The shaft C of a clock rotates a disc 1 and the disc rotates a snail cam 8, the gearing being so arranged that the disc rotates once in six hours and the cam rotates once a week. The cam moves a sliding member or a pivoted arm 16 to which a finger 18 is flexibly connected at 19. The disc is marked with a spiral line or groove 1B, and the finger 18 traverses the spiral and moves slowly outwards from the centre. A pivoted lever 23 carries an abutment 24 and a depending arm 22, and a spring keeps the arm 22 in contact with the finger 18. Small pins, screws, or like projecting pieces are inserted at pre-determined places on the spiral line on the disc, and when such a piece comes into contact with a tappet 20 on the finger 18 it swings the finger and the lever 23 outwards. The clock shaft C also rotates a cam 32 which rocks a lever 27 having another lever or searching-member 25 pivoted to its free end. One end of the lever is connected with a suitable switching member, such as a mercuty switch 36. Normally the oscillations of the lever 27 do not tilt the switch 36, but when the lever 23 moves outwards, an abutment 24 at its end stops the free end of the lever 25 and causes the switch 36 to tilt and open or close the circuit of an indicating or signalling device. The lever 23 may be dispensed with, the abutment 24 being fixed to the end of the finger 18. In a modification, the disc 1 may be covered with insulating material which is perforated at pre-determined places. A contact member carried by the finger 18, or by a slide operated by the cam 8, falls into the perforations and completes an electric circuit. The disc may be interchangeable with others having different pre-set programmes, and it may be replaced by a cylinder or cone.

Title: Improvements in or relating to the preparation of alkyl acylaminocyanoacetates
IPC: C07C233/00
Filed: 1945-10-12
Abstract: Alkyl acyl-aminocyanoacetates are obtained by reacting an alkyl isonitrosocyanoacetate with a cold aqueous solution of a water-soluble metal hydrosulphite, e.g. sodium hydrosulphite and an acylating agent such as a lower aliphatic acid anhydride, e.g. acetic or propionic anhydride.  The alkyl isonitrosocyanoacetates are obtained by nitrosating alkyl cyanoacetates and may be used without isolation from the resulting reaction mixture.  In examples: (1) ethyl isonitrosocyanoacetate is treated with acetic anhydride and sodium hydrosulphite at 0-10 DEG  C. to produce ethyl acetylaminocyanoacetate; (2) ethyl cyanoacetate is treated with sodium nitrite followed by treatment with acetic anhydride and sodium hydrosulphite to produce ethyl acetylaminocyanoacetate.

Title: Improvements in or relating to a method of and a device for eliminating spurious information in a signal transmission system
IPC: H04J1/14
Filed: 1957-08-23
Abstract: 824,065. Multiplex transmission systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Aug. 23, 1957 [Aug. 23, 1956], No. 26733/57. Class 40 (4). In a multiplex transmission system arrangements are provided for eliminating spurious supervisory signals due to momentary interruptions of the main transmission path. Fig. 3 illustrates n channels obtained after demodulation and filtering of an incoming frequency division multiplex system, respective supervisory signals being received as 3825 c/s. signals over lines L1 . . . Ln which signals after detection at M1 . . . Mn operate supervisory relays R1 via their lower coils to apply positive potential to leads m1 . . . mn. In addition a group pilot signal (which may also be used for automatic gain control) is demodulated to produce over lead L a 3920 c/s. signal which is detected at M whose output kicks relay R in the released condition. In the event of a transmission failure R (which may be electronic) closes its contact rapidly to fire all tubes G1 . . . Gn whose associated relays R1 . . . Rn are at the time operated, to maintain such relays operated over their upper windings. When the transmission path is restored R operates more slowly than R1 . . . Rn to leave the latter once more under control of the 3825 c/s. signals. The invention is applicable both to systems in which the 3825 c/s. is normally present during a connection and systems in which it is normally present when no connection exists.

Title: A method of making peptides
IPC: C07K1/12
Filed: 1965-06-25
Abstract: An apo-enzyme is prepared from fresh calf liver by mixing the coarsely ground material with phosphate buffer (pH 7.6) and sodium disoxycholate, acidifying to pH 5, separating the ppt. immediately, adjusting to pH 7.6, adding (NH4)2SO4 to 38% w./v., rejecting the ppt., adjusting the supernatant soln. to 50% w./v. with respect to (NH4)2SO4, collecting the ppt., dissolving it in slightly ammoniacal H2O, dialysing at a controlled pH of 7, decolorizing the soln. with C, adsorbing the material on diethylaminoethyl cellulose ion exchange column, eluting with buffered-KCl soln. (pH 7.6), dialysing the eluate and freeze drying the dialysate.  A 5% soln. of the freeze-dried material in 70% EtOH contg. 0.001 M HgCl2 yielded crystals of the Hg salt.  The free enzyme is liberated from the inactive salt by passing an aq. soln. through an ion-exchange column in thioacetic acid cycle.  The apo enzyme is activated by the addition of ascorbic acid or other suitable reducing agents.  The enzyme catalyses the synthesis of polypeptides from amino acids or smaller peptide units in the presence of a nucleotide.ALSO:Peptides are prepared by condensing an alpha amino carboxylic acid ester and an alpha-amino acid or pepetide of sufficiently low pK value in the presence of an enzyme which catalyses peptide formation and sufficient nucleotide to activate the reacting amino group.  The enzyme may be obtained from calf's liver and the reaction may be performed at a pH 7-8 and in the presence of Mg ions.

Title: Improvements in or relating to the treatment of mineral phosphates
IPC: C05B13/02
Filed: 1937-10-07
Abstract: Mineral phosphates are melted, and the whole of the molten material is heat-treated in the form of a thin layer which is advantageously acted upon by gases or vapours.  The thickness of the layer is less than 1 inch.  The phosphate, preheated if desired, and admixed for example with sand, may be melted upon the upper part of an inclined surface, and the melt flowing down the surface is acted upon and heated by hot gases conveyed thereover. The inclined surface may be in the form of a groove or gutter, or of a cone, and may be formed with a lower part of less inclination than the upper part, or may terminate in a horizontal surface. The material which flows down the inclined surface may be delivered into a melting furnace of known type wherein the heating action is continued.  The phosphate, with or without admixed flux, may be heat-treated prior to its delivery to the upper part of the inclined surface.

Filed: 1975-06-27
Abstract: 1502169 Electric projectile fuze MEFINA SA 27 June 1975 [5 July 1974 30 May 1975] 27238/75 Heading F3A An electric projectile fuze whose sensitivity to impact is adjustable, comprises a pulse generator 1, Fig. 1, a pulse counter 10 for firing a fuse 4 after receiving at least one pulse, an electromagnetic transducer comprising coils 6 and 7 and a relatively movable ferromagnetic core 8 whose proximity to at least one of the coils determines whether the amplitude of the pulses will be sufficient to exceed the threshold voltage of a Zener diode 9 and thereby be able to activate the counter 10, and means for adjusting the relative initial position of the core to set the senstivity of the fuze. In one embodiment, Fig. 2, the coils 6 and 7 are carried by an inertia block 15 and are movable forwards on slowing down, or impact of, the projectile. The ferromagnetic core 8 is movable rearwards by the pushing in of a disc 12. The relative initial position of the coils and the core and thereby the distance that the core must move relative to the coil(s) on impact, or slowing down, of the projectile to activate the counter, is adjustable by rotating a member 24 which causes a pin 22 to climb an inclined surface 23 and thereby lift the inertia block 15. In other variations the core is fixed and one or more of the coils is movable. The safety of the projectile depends not only on the delay produced by the counter 10, Fig. 1, but also on the time required by a circuit 3 to supply a sufficient charge through a capacitor C 1  to permit firing of the fuse 4 through a transistor T. The circuit 3 may be so arranged that after a given time, the voltage of capacitor C 1  reaches a sufficient value to make transistor T conduct, which permits self-destruction of the projectile.

Title: A method and a device for developing Crimps in Conjugate Filament Yarn
IPC: D01D5/32
Filed: 1967-06-13
Abstract: 1,174,865. Filament crimping apparatus. KANEGAFUCHI BOSEKI K.K. AND SNIA VISCOBA SOCIETA NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S,p.A. 13 June, 1967 [17 June, 1966], No. 27242/67. Heading B5B. Crimps are developed in conjugate filament yarn by heating the yarn by passage through a tube heater, a section through which is a closed curve, located between feed rollers and withdrawal rollers (not shown), said tube heater having at least two bends so that the running yarn is contacted with the inner wall of the tube at the points of bending, and undergoes at least two changes of direction within the tube, the ratio V 1 /V 2  of feed velocity (V 1 ) to withdrawal velocity (V 2 ) being at least 1-2. The tube heater may be bent in either a plane or in three dimensions, and in either a regular shape as in Figs. 2 to 6, or in an irregular shape, as in Fig. 7. To minimize friction the inner surface of the tube should be finished as smoothly as possible, for example an aventurine finish may be effected by chemical polishing. Suitably, the degree of roughness in the inner surface of the tube is preferably IS to 10S, preferably 3S to 5S, where S is the average value of the height of uneveness of the uneven surface H when measured 10 times, and expressed in microns. The tube may be heated electrically, either applying an electric current to the tube itself to generate heat or by high frequency heating, or by the use of a heating medium such as a gas, liquid or solid. The tube may be surrounded by a heating member, which in turn is surrounded by an insulating member. The use of the apparatus enables improved crimped filament yarn to be obtained, having little uneveness of crimp, at a higher speed than by conventional methods. In example 1, a conjugate filament comprises a nylon-6 component, and a 90 : 10 copolymer of nylon-6 and polyhexamethylene isophthalamide, in side-by-side relationship. After melt spinning, the filament is wound and drawn to 3À69 times its original length at room temperature. This drawn yarn is passed through a stainless steel tube having an inner diameter of two mm., a degree of roughness of the inner surface of 3S and a length 50 cms. held at 175‹ C. and using a feed ratio V 1 /V 2  of 1-45, to develop crimps, using tubes having 2 to 5 contact points, and feed velocities of 274 to 290 m. per min. Example 2 is similar except that a feed velocity of 200 m. per min. is used.
