Title: Improvements in or relating to Ultrasonic Welding Apparatus
IPC: B29C65/08
Filed: 1967-07-28
Abstract: 1,193,838. Seaming non-metallic sheet material. REALISATIONS ULTRASONIQUES. 28 July, 1967 [5 Aug., 1966], No. 34925/67. Heading B5K. An ultrasonic welding device is provided with means for displacing a welding head 5 towards parts 1, 2 to be welded and to determine its position at the beginning of its contact with the part 1 and means for limiting to a predetermined amount the further displacement of the head 5 in the direction towards the part 1 from the said position. In one embodiment, Fig. 1, a plastics cover 1 is welded on to a plastics box 2 by the head 5 carried by an ultrasonically vibratable member 4 connected to a magnetostrictive transducer 6. The member 4 is supported at a node of vibration by a flange 7 fixed to a tubular member 8 having a lower flange 9 which carries an electromagnet 11. The member 8 is displaceable through a ball-bearing slide 10. A dial indicator 13 is provided with a vertically displaceable rod 14 carrying a blade 14 of soft magnetic material attractable by the electromagnet 11 when the latter is excited. In operation, the position of an electric contact 20 is preset so that a needle 21 touches it when the rod 14 has undergone a predetermined displacement. The member 8 is lowered and the flange 9 closes a microswitch 19 and, after a time delay, determined by a relay 17, the latter closes a contact 16 so that the blade 15 is attracted by the electromagnet 11. Simultaneously, the head 5 is ultrasonically vibrated. During the welding, the head 5 continues to move slightly downwards until the needle 21 touches the contact 20 and the ultrasonic vibrations are immediately cut-off by a circuit 22 which after a time predetermined by a timing mechanism therein moves the member 8 upwardly towards its rest position. In another embodiment (not shown), the dial indicator and the electromagnet are omitted and the member 8 and the support 3 are each provided with an adjustable stop. The ultrasonic vibrations are started when the welding head contacts the upper part to be welded and are arrested when the stops contact each other. In a further embodiment (not shown), the means to cut off the ultrasonic vibrations when the two stops contact each other is omitted and the vibrations are produced during a time determined by a timing mechanism using fixed stops to limit the penetration of the welding head.
Patent GB-605311-A (GB)
Title: Improvements in the manufacture of methionine
Filed: 1945-12-27
Abstract: Methionine is prepared by reacting hydrogen cyamide and methyl mercaptan with acrolein to form alpha - hydroxy - gamma - methylthiol - butyronitrile, reacting the latter with ammonia to convert the hydroxyl group to an amino group and hydrolysing the nitrile group to a carboxyl group.  The reaction may also be effected by reacting acrolein with methyl mercaptan to form beta-methylthiol-propion-aldehyde which is then reacted with hydrocyanic acid to form the corresponding cyanhydrin or by reacting acrolein with hydrocyanic acid to form the cyanhydrin which is then reacted with methyl mercaptan.  In each case the reaction is completed as above by reacting with ammonia to convert the hydroxyl group to an amino group and hydrolysing the nitrile group.  The reaction between acrolein and methyl mercaptan and between acrolein cyanhydrin and methyl mercaptan are preferably conducted in the presence of a small amount of potassium cyanide or other alkali metal cyanide which serves as a catalyst. Anhydrous ammonia is preferred to replace the hydroxyl group by the amino group, but concentrated aqueous ammonia may be used.  In examples, methionine is produced by the three methods referred to above, liquid hydrocyanic acid being employed.  A small amount of potassium cyanide is used as catalyst and relatively low temperatures are employed for the production of the alpha - hydroxy - gamma - methylthiol butyronitrile.  The hydrolysis of the nitrile group is effected in each case by boiling with concentrated hydrochloric acid and after the precipitated ammonium chloride is removed the methionine is precipitated by means of an alcoholic solution of ammonia or of pyridine.

Title: Pneumatic control
IPC: F15B11/15
Filed: 1972-07-26
Abstract: 1355490 Pneumatic control systems LUWA AG 26 July 1972 [30 July 1971] 34990/72 Heading F1P In a pneumatic control for automatically reheating an operational cycle a logical NOT- element 12, Fig.1, is connected in series with a logical timing element 14 which is connected back to the NOT-element via a conduit 26. Thus, the pressure signal is returned after a time delay to the NOT-element to extinguish the pressure pulse. This also removes the pulse from conduit 26 so that the sequence begins again. Fig. 2 shows an arrangement of a NOT-element 42 with a time delay element 44 which comprises a throttle check valve 46, a volume chamber 48 and an identification element 50. When the pressure in conduit 49 amounts to 60% of the pressure at the inlet 47 the identity element switches so that at outlet 65 there appears a pressure signal which passes via conduit 64 to the NOT-element 42. As soon as the pressure at inlet 67 amounts to 20% of the pressure at conduit 56 the signal at conduit 58 is negated. This allows the cycle to recommence. Fig. 3 (not shown), illustrates how this type of control may be used to cause reheated operation of a piston and cylinder device.

Patent GB-667901-A (GB)
Title: Improved process for the intensive manufacture of sulphuric acid
IPC: C01B17/86
Filed: 1947-12-31
Abstract: In making sulphuric acid by reacting sulphurous gases, oxygen and water in the presence of nitrosyl-sulphuric acid dissolved in concentrated sulphuric acid having a concentration of over 60 DEG B<\>ae, the reaction for the formation of sulphuric acid is effected concurrently with the recovery of the nitrous gases liberated by the reaction of SO2 with the nitrosyl sulphuric acid, and for each molecule of absorbed SO2 not less than 5 molecules of nitrosylsulphuric acid are employed, the acid to be transformed into the final product being diluted before its denitration or in the same denitration apparatus.  The reaction may be effected in an absorption system composed a number of compartments e.g. an arrangement of absorption towers, in which sulphurous gases are sprinkled with nitrosulphuric acid of constant composition drawn from a single container which is fed by the acids from the different compartments. Alternatively, the reaction may be effected by causing the nitro-sulphuric acid to circulate continually in a single circuit either from the last compartment to the first or vice versa, Fig. 2 (not shown).  The composition of the circulation acids may be maintained constant by introducing water, as liquid or steam, or dilute nitric acid, at any suitable point of the absorption cycle. Denitration may be effected by heating or by the action of cool sulphurous gases prior to their introduction into the system, the liberated nitrous products being returned to the absorption system. Hot sulphurous gases are cooled before use in denitration and the heat therefrom is utilized for supplementary concentration of the denitrated acid to give a final product, e.g. 60 degrees Be H2SO4.

Working at specified temperatures.-A method of processing non-austenitic steels to improve their physical and mechanical properties Comprises working the steel while it is heated to a temperature above 850‹ F. but below the lower critical temperature of the steel composition. This process imparts high strength with exceptionally low residual stresses and a lowwarping value to the steel which may be in the form of a not-rolled bar having a pearlitic structure in a matrix of free ferrite. Advantageous high compressive stresses are formed on the outer area of the bar, such stresses being indicated by a negative warping value, by drawing the bar through a die either at about 850‹ F. with 36 per cent draft, or at about 875‹ F. with 19 per cent draft or at about 900‹ F. with 12 per cent draft followed by rapid cooling by quenching or spraying. These high compressive stresses increase the tortional fatigue value of the steel bar. Specifications 423,868, 715,152 and 761,150 are referred to.
