Abstract: 1481960 Offshore platforms; structural joints C G DORIS (COMPAGNIE GENERALE POUR LES DEVELOPPEMENTS OPERATIONNELS DES RICHESSES SOUS-MARINES) 5 Nov 1974 [29 Nov 1973] 47730/74 Headings E1H and E1W A concrete jacket is built from two sections which are constructed separately and then mounted one on top of the other and the two sections comprise a bottom part formed by a base 10 with stiffeners 11, peripheral wall 9, tubular members 8 and hollow columns 3 and a top part formed by a deck 7, hollow legs 6, collars 18 and tubular members 17. The columns 3 are attached integrally to the members 8 and are surrounded by wall 9. Columns 3 and the tubular members 8, 17 are internally divided by bulkheads 14, 16, 17a into buoyancy tanks with associated ballast lines 15, 16 and 19. Fabrication. The deck 7, collars 18, tubular members 17 and the lowermost portions of the legs 6 are built in a dry dock with the bridge 7 above the members 17 and resting on, a sliding formwork which is used to cast the legs 6. After flooding the dock, the partially built and buoyant top section is moved to a sheltered location where erection of the legs 6 is completed afloat, the bridge 7 being simultaneously raised as the legs 6 are formed by a hoist mechanism and finally connected to the legs. Whilst the top section is being completed afloat, the bottom section is partially constructed in the dry dock and the columns 3 are completed with the section afloat at another location. The columns 3 are sealed at their upper ends and are each attached to an auxiliary buoyancy chamber. The bottom section is then towed to a location having a flat water bed where it is sunk by flooding the buoyancy tanks in member 8. The auxiliary buoyancy chambers are removed and the top section is positioned above the sunken bottom section so that the collars 18 are connected to columns 3. After joining the top and bottom sections together, the jacket is partially deballasted, towed to its final location and then sunk to the bottom. Connecting the deck 7 to the legs 6 is performed using openings 23 in the deck 7 in to which are positioned sleeves 27a and steel reinforcement 28a which cooperate with sleeves 27 and fixings 28 located in the concrete of the deck 7 and legs 6 at an earlier building stage. After concrete has been poured and set in the openings 23, prestressing cables 30 are assembled in the sleeves 27, 27a whereafter further concrete is poured into these sleeves.  The legs 6 are connected to the columns 3 by prestressing cables 45 anchored at points 45a 45b. This work is undertaken using a panel 41 which is used to seal off the open bottom of a leg 6 which has a male projection 37 cooperating with a female recess in the upper end of the columns 3. Inflatable seals 40 prevent ingress of ambient sea water.

Title: Low speed data transmission system
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04L1/18
Filed: 1964-11-27
Abstract: 1,073,929. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. Nov. 27, 1964, No. 48245/64. Heading H4P. In a data transmission system errors are detected by returning to the transmitter the signals received, and are corrected by repetition. The receiver output record contains no error, a receiver store being controlled by the received data. The embodiment described comprises serial or parallel tape input. Each character transmitted steps a counter forwards and is stored and each character returned from the receiver and agreeing with the corresponding stored character steps that counter backwards. If the counter becomes full (four characters) the tape reader stops. If the stored and return characters disagree the store is filled to four characters and then the tape reader is stopped and a multicharacter cancel signal transmitted. This is followed by the four stored characters. At the receiver an eight-character store precedes the output perforator or teleprinter and normally acts as a shift register. When a cancel signal is detected read-out from the store ceases and the next four characters received, which are the repeated characters, overwrite the four oldest characters in the receiver store. The next four characters received overwrite the cancel signal, and the store reverts to its action as a shift register. No error is present in the output record. If an error is detected during a repetition cycle an alarm is actuated and the system closed down. The fortuitous occurrence in a message of the cancel signal sequence is prevented from causing mal-operation by deliberately mutilating the last character in the sequence, whereby repetition is automatically initiated.

Abstract: 983,360. Conical mills; mixing appliances. FILMFABRIK AGFA WOLFEN VEB. Dec. 10, 1963, No. 48800/63. Headings B1C and B2A. Apparatus for mixing, emulsifying and comminuting a solid/liquid mixture, e.g. cellulose xanthogenate in caustic soda, comprises a casing 8 containing a grooved, conical friction-disc 2 and a rotatable, correspondingly cone-shaped, grinding wheel 1 having recesses forming inlet and outlet compartments 13, 14 disposed alternately in the direction of rotation of the wheel and communicating with one another through the adjustable working gap 17 between the disc and wheel which is on the inlet side only of the apparatus ; the grinding wheel 1 has on the side opposite the grinding side substantially triangularshaped cut-out portions 21, which permit automatic self-adjustment of the working gap 17, while the shape of the closed inlet compartments 13 is such that the forces produced therein, through the centrifugal pressures occurring, urge the grinding wheel away from the friction disc. A disc 3, smooth on the side facing the wheel 1, is fixed to the casing at a predetermined distance 4 from the wheel, and the shaft 12 includes an axiallyslidable ball-bearing 10. In operation, material to be ground is supplied by a feed-screw 5 through apertures 16 to the inlet compartments 13 of the wheel 1. As the wheel rotates it is urged away from the disc 2 until the ball-bearing 10 on the shaft 12 lies against a cover 18, at which point the working gap 17 attains its maximum width. One edge 20 of the cut-out portions 21 is at right angles to the inner wall 22 of the outlet compartment 14, and the other edge 23 is parallel to the wall 22. The cut-out portions are of such area that the pressure of the ground material in the gap 4 after the lumpy material has been ground in the gap 17, and the axial force on the grinding wheel, are greater than the opposing axial force in the closed inlet compartment so that the wheel is moved to the minimum width of the gap 17. Consequently the grinding wheel 1 is moved to the position for minimum width of working gap 17. The conical face of the disc 2 is grooved to provide hardened cutting edges.

Abstract: 1414559 Printed circuits URALSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI POLITEKHNICHESKY INSTITUT IMENI S M KIROVA 22 Oct 1973 49046/73 Heading H1R In the manufacture of a multilayer printed circuit, through holes are metallized so that one metallization contacts directly the edges of conductor layers 1 by applying an auxiliary layer of conductive material to the hole wall by a non-electrolytic process, the conductive material is selectively removed from the edges of layers 1, leaving auxiliary conductive material layers 3 on the edge faces of dielectric layers 2, 2<SP>1</SP> and interconnection layer 4 is applied electrolytically. The auxiliary layer may comprise a metal more electropositive than the metal of conductor 1, e.g. it may be palladium deposited from a solution containing palladium chloride, copper chloride and sulphuric acid, or silver deposited from an ammoniacal silver nitrate solution, or palladium deposited from a solution of palladium sulphate and hydrochloric acid. The layer formed is porous where it coats the edge surface of conductors 1 and this part is removed by treatment with a solution which reacts selectively with the metal of conductors 1, e.g. in the case of copper, solutions containing CuCl 2 .2H 2 O and HCl, or (NH 4 ) 2 S 2 O 8  and H 2 SO 4 , or CrO 3  and H 2 SO 4  or NH 4 OH, (NH 4 ) 2 CO 3  and (NH 4 ) 2 S 2 O 8 . The solution may additionally react more rapidly with the porous part of the auxiliary layer than the non-porous part, e.g. solutions containing H 2 O 2  and H 2 SO 4  or H 2 O 2 , (NH 4 ) 2 S 2 O 8 , HCl and Versene-T. Alternatively the auxiliary conductive layer may comprise metal chalcogenides deposited from solutions containing complex salts, metal salts, buffer substances and a source of sulphur, selenium or tellurium such as thiourea. Again the portion covering the edge surfaces of conductors 1 is removed by a solution reacting selectively with the metal of conductors 1, or, when the metal of the chalcogenide is different from that of conductors 1, by a solution which also reacts with that portion of the deposited chalcogenide overlying the metal edge surface. The conductivity of the chalcogenide may be increased by heating at up to 400‹ C. after removal from the plating solution. In any of the embodiments, the plating may be carried out in an A.C. field, preferably using auxiliary electrodes which may be insulated from the electrolyte to prevent heating. Plating may also be carried out in an ultrasonic field, and such a field also accelerates removal of the part of the auxiliary layer covering the metal edges. The walls of the through holes may be first sensitized for plating by treatment with a solution containing Sn<SP>2+</SP> or Ti<SP>3+</SP> ions. Further, as shown, relatively wide portions of the wall may be divided by metal layers 1<SP>1</SP> which need not be part of the circuitry but improve the mechanical stability of the assembly.

Title: Apparatus for controlling the acceleration of a gas turbine
IPC: F01D19/02
Filed: 1970-10-19
Abstract: 1330853 Automatic acceleration control GENERAL ELECTRIC CO 19 Oct 1970 [19 Nov 1969] 49508/70 Heading G3R The acceleration of a gas turbine is controlled during the starting period by a speed-responsive signal which is applied through a network comprising capacitor 103 and resistors 105,107, differentiating the signal to the base of transistor 111. The emitter circuit of the transistor comprises a potentiometer 117 which is connected through an operational amplifier 45 to a circuit for regulating the amount of fuel supplied to the turbine. Adjustment of the potentiometer 117 controls the gain of the system while resistor 107 provides means for adjustment of the point at which acceleration control commences, without interaction with other factors controlling the operation of the turbine. The system comprises main speed and temperature controllers as well as a main start-up controller which is associated with the acceleration controller. Each of the main controllers applies a signal through a diode to a minimum value gate which is connected through an amplifier to the fuel control circuit. The speed controller assumes control after the turbine has started, while the temperature controller prevents thermal shock by restricting the input of fuel. The gate allows that controller which has the least positive output signal to take over control of the turbine, Fig. 1, (not shown). Initially the turbine is turned mechanically and fuel is witheld until a predetermined speed is reached. At that point, a negative signal is applied to line 43 so that the output of amplifier 45 becomes more positive to increase the fuel input to a given level. As soon as a flame is detected, the fuel supply is reduced for a warm-up period, at the end of which the potential of the line 43 is gradually increased in a negative sense by a capacitorresistor network (57, 59), Fig. 2, (not shown. The acceleration controller provides a positivegoing feedback signal to keep the acceleration constant. At the end of the acceleration period the turbine receives maximum fuel supply for full speed operation, acceleration control being reintroduced during load-lost conditions, Fig. 2, (not shown).
