Abstract: 1,075,648. Welding by fusion. VYSKUMNY USTAV ZVARACSKY MHD. Nov. 2, 1965, No. 46302/65. Heading B3R. A guide nozzle and contact device for guiding a consumable electrode to the weld zone comprises two side members (2) joined by a web (6) to form an elongated channel, and a tube (5) removably mounted in the channel and through which the electrode passes. In a nozzle for electro-slag welding the channel and tube (5) are curved and the tube is secured in place by an abutment (7) detachably secured to the channel. Welding current is fed to the abutment. A wearing block (14) of hard metal is soldered into the end of the guide. The electrode is adjustably deflected by a removable deflector 15 attached to a lever 10 whose position is sot by a cam actuated by a knob 17. A ceramic roller 16 on the deflector prevents contact of the nozzle with the work.

Title: Memory units
IPC: G06F12/16
Filed: 1973-10-05
Abstract: 1400650 Faulty memory correction INTERNATIONAL BUSINESS MACHINES CORP 5 Oct 1973 46555/73 Heading G4A Data read from a memory array 14, 16, 18, 20 is checked by an error detection circuit 66, and if an error which the circuit 66 is incapable of correcting is detected, the address applied to the array is combined with modifier numbers in a predetermined sequence to effectively skew the relative positions of the bit cells accessed by a presented address until the data is correctable by the circuit 66. As an example a rudimentary store holding four 4-bit words is shown, each circuit card 14-20 storing a corresponding bit from each word. The modifier numbers are generated by feedback shift registers 52 which are pre-loaded with the inputs S1 shown, it being assumed that register 52a stores the combination 00 and is unchanged in the operation which follows. Registers 52b-52d operate as Galois field counters to generate 10, 01, 11 in the cyclic sequence 68 in response to successive shift pulses. Assuming that bit positions 2 and 0 are faulty in cards 16, 20 respectively, when word 3 is addressed, the actual bit positions accessed will be as shown in columns T1 and will include the faulty positions on cards 16, 20, resulting in detection of a double error condition by circuit 66. Application of a shift pulse to registers 52 skews the effective addresses of the bit positions as shown in column 72 so that the faulty bit positions are now effectively transposed to different words W0, W1, and accessing of either of these words would result in a single error condition which is correctable by circuit 66. If a further fault subsequently occurs in bit position 3 of card 16, addressing word 1 will again result in a double error condition and registers 52 will be stepped again to transpose the effective addresses as shown in columns T3. In this new state, the faulty bit positions 2, 3 of card 16 are seen to be in different words to the faulty position 0 in card 20.

As shown, a rocket motor 14 with a nozzle 21 is mounted on a rod 17 connected by a bell-crank 11 to a platform 5, pivoted at 6, on which the airman sits. The motor is spring-loaded by a spring 19 into its extreme aft position shown in solid lines, and the spring is pre-loaded so that movement only occurs when the airman is subjected to the acceleration of ejection. A pack of two or more rocket motors may be fitted, with separate or interconnected nozzles, or with a single-nozzle.
Patent GB-1081760-A (GB)
Title: Preparation of oximes
IPC: C01B21/14
Filed: 1964-11-24
Abstract: Oximes are prepared by reacting an aqueous solution of a hydroxylamine salt with an aliphatic, alicyclic or aromatic aldehyde or ketone in the presence, either at the beginning of the reaction or after the reaction has started, of both a weak acid having a dissociation constant of 2 x 10-1 to 10-6 at 25 DEG  C., and at least one soluble salt thereof in such a ratio that the pH of the reaction mixture during the first and greater part of the reaction is in the range 1-4, recovering the oxime and separating the dissolved salt from the acid liberated during the reaction. Specified weak acids are ammonium bisulphate, phosphoric, formic, acetic, lactic, citric and benzenesulphonic acids.  It is preferred to use a hydroxylamine salt derived from the weak acid, and to use the acid recovered from the reaction mixture to form further hydroxylamine salt starting material.  To effect complete conversion to the oxime to pH of the reaction mixture during the last part of the reaction is raised to a value greater than 4, e.g. by adding ammonia.  The process is illustrated by referceen to flow diagrams (not shown).

Title: A method of compensating the pyroelectric effect in electromechanical transducers, particularly in ferroelectrics, and an arrangement for performing the same
Inventor: WUNSCHMANN WOLFGANG
Filed: 1969-10-04
Abstract: 1286987 Piezo-electric elements METRAMESSUND FREQUENZTECHNIK RICHARD WEBER KG 4 Oct 1969 48853/69 Heading H1E The pyro-electric effect in electromechanical transducers employing the longitudinal, transverse, or shear, piezo-electric effect is compensated by the use of two pairs of electrodes, the pairs being of such relative disposition and area, and so interconnected, as to ensure the mutual cancellation of the changes of surface charge arising at the electrodes due to the pyro-electric effect upon a change of temperature. In the arrangement of Fig. 4, the electrode areas or pyro-electric coefficients of the two plates 6 and 7 are chosen such that, when connected as shown, cancellation of the pyroelectric surface charges occurs, the mechanical force for application to the transducer being arranged to apply tensile stress to one plate and compressive stress to the other, in order to prevent cancellation of the signal which results from mechanical strain. For the shear loaded piezo-electric element of Fig. 6, pyro-electric charges appearing at the principal electrodes 4 and 5 due to the polarization vector not being strictly parallel to those faces are compensated by the pair of electrodes 8 and 9 (electrode 8, only, appears inFig. 6) which are connected to the principal electrodes. The arrangement facilitates the use as transducers of ceramic ferro-electric materials, which are pyre-electric.
