Title: Ring rail lifting method and equipment for spinning machinery
IPC: D01H1/36
Filed: 1969-08-14
Abstract: 1287107 Building motions NIHON SPINDLE SEIZO KK 14 Aug 1969 [14 Aug 1968] 40752/69 Heading DID [Also in Division H2] A building motion for a ring spinning machine is controlled by generating pulses (at 1) at rates related to the speed at which thread is supplied to the cop being wound, feeding pulses in a sequence of predetermined rates to a motor 2 driving a ring rail along the cop, counting the pulses during each traverse of the ring rail and terminating the traverse when a predetermined number of pulses has been counted and reversing the ring rail at the end of each traverse.  As shown, pulses are photoelectrically generated at 1 by a device connected to the front rollers of the machine. These pulses are fed either directly, or via frequency converter 10, to the motor controlling the drive to the ring rail. The motor, and hence the direction of travel of the ring rail, is reversed by contacts M1, M2 and M3 acting on switches K1, K2. The contacts Ml M2 M3 and M4 are operated by a motor driven control rod 53 which reciprocates in unison with the ring rail. This control rod 53 also controls the fluid flow to the piston 37 causing reciprocation of the ring rail. The control rod 53 slides the contacts along during part of its traverse thereby adjusting the position of the traverse. At the start of winding the motor 2 is rotated at high speed by pulses from generator 9 to cause rapid reciprocation of the ring rail. Reversal of the ring rail is caused by the reciprocating control rod 53 alternately engaging contacts M2 and M3. After a preset number of reciprocations has been counted in C2, contact M2 is rendered inoperative so that the ring rail is now reversed by contacts M1 and M3.  During the building motion the ring rail is reversed by contacts M1 and M3. As the control rod 53 rises during each reciprocation in unison with the ring rail and engages contact M1, it thereby starts counter C1. After a preset number of pulses from generator 1 have been counted, the counter Cl causes the ring rail to fall. During the pulse counting period of counter C1 the control rod 53 (and hence the ring rail) has continued to rise sliding contacts M1, M2 and M3 with it, thereby adjusting the position of the traverse of the ring rail. At the end of winding a yardage counter causes a high speed descent of the ring rail and control rod 53 and causes the lower reversing contact M3 to be inoperative. The control rod 53 therefore continues to descend (sliding contacts M1, M2 and M3 with it) until it meets contact M4. The latter contact causes the ring rail to remain stationary for a while to wind a transfer tail below the package and then a timer allows the ring rail to rise to the doffing/ start position.

Title: Improvements in or relating to multiple walled corrugated pipes
IPC: B21C37/12
Filed: 1960-11-28
Abstract: 907,095. Making helically seamed corrugated tubing; coiling; soldering. METALLSCHLAUCHFABRIK A.G. Nov. 28, 1960 [Dec. 4, 1959], No. 40814/60. Classes 83 (2) and 83 (4). [Also in Group XXVIII] A method of producing a double or multiple walled corrugated pipe consists in helically winding a single corrugated band so that the windings of the band overlap by a plurality of corrugations. A corrugated metal band 4 having somewhat more than two corrugations is wound on a mandrel so that always more than one corrugation is overlapped. The threefold band layer thus produced at the corrugation peaks is welded together at 5 by resistance welding or welding by local induction heating or by high frequency. A triple walled pipe may similarly be produced by winding a band having somewhat more than three corrugations so that it overlaps by more than two corrugations. Instead of welding the tubing may be soldered, in which case, Fig. 5, a solder wire 7 is wound with the band to lie in a depression 10 in the top of the corrugations. The solder is melted, either continuously, concurrent with the winding, or after winding of a pipe has been completed, by electric resistance heating, by induction heating or by a gas flame. Specification 528,392 is referred to.

Abstract: 1328112 Semi-conductor switching circuits MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 2 Sept 1970 [17 Sept 1969 18 Sept 1969] 42082/70 Heading H3T [Also in Division H2] In a power supply circuit having current control means including a transistor Tr1, e.g. of a voltage regulator, and a thyristor Dth which is rendered conductive in the event of overcurrent to render the transistor substantially non-conductive, means are provided to render the thyristor non-conductive after a time delay to restore the current in the supply circuit. In the arrangement shown, excessive load current through a resistor R 6  causes the voltage across the resistor to trigger the thyristor Dth into conduction. This causes a transistor Tr3 to conduct to reduce the potential at the base of the transistor Tr1, which substantially cuts off the load current. The increase in voltage at a point B causes a capacitor C 3  to charge. When the charge on the capacitor is sufficient, a transistor Tr5 is rendered conducting to shortcircuit and turn off the thyristor Dth. In an alternative arrangement, Fig. 4 (not shown) the time delay is provided by a photoconductive cell connected across the thyristor and a lamp connected in series with the thyristor.

Abstract: 1339811 Rolling mills MOELLER & NEUMANN GmbH 13 Sept 1971 [24 Sept 1970] 42535/71 Heading B3M A hydraulically tensioned tie rod, which may be used to clamp together components of a rolling mill, is provided with an annular piston 5 and an annular cylinder 4, the piston acting (through a ring 7) on radial projections 1a on the rod, and the cylinder acting (through a base 3) on one component 2 to be clamped. By pressurizing on chamber 22 between the piston and cylinder, the ring 7 is urged upwardly and causes the rod to stretch. This produces a clearance 5 between further projections 1b on the rod and a second ring 8. The ring can then be rotated from the position shown in Fig. 2 until the inner projections 8a of the ring are located beneath the projections 1b. On release of the pressure in the chamber the tie rod contracts slightly until supported (still in a state of tension) by the ring 8. In this operative condition, the ring 7 can be rotated until its inner projections are clear of the projections 1a and the cylinder 4 and piston 5 can be lifted clear of the rod. Similarly, when the ring 8 is rotated, the upper component 2 is able to be lifted from the rod. The rings 7 and 8 are each rotatable by slidable cylinders 10 which are each provided with rack teeth and slide on a fixed piston 12. Between the piston 5 and the cylinder 4 is a floating piston 23 whose axial movement is limited, bore 28 permitting a supply of fluid to be directed between the pistons 5 and 23 if the piston 5 is to be raised further.

Title: Process for treating hydrocarbons
IPC: C07C4/16
Filed: 1966-09-23
Abstract: A process for hydrodealkylating an alkyl aromatic hydrocarbon feed comprises mixing the feed with a H2-containing gaseous stream, the quantity, temperature and rate of injection of the stream being selected to raise the temperature of the feed substantially instantaneously to a value between the autogenous and final reaction temperature of hydrodealkylation and hydrodealkylating the alkyl aromatic feed, preferably by heating the mixture. In a preferred embodiment, two hydrogen-containing gaseous streams are used, one to raise the temperature of the feed to that at which the dealkylation is autogenous and the second to raise the temperature of the feed to between the autogenous and final reaction temperatures. Preferably, the first H2-containing stream contains at least 50% by vol. H2 and the mol. ratio of stream to the alkyl aromatic hydrocarbon feed is from 1:1 to 2:1.  The temperature of the first mixture may be 535-595 DEG  C.  The second stream may also contain at least 50% by vol. H2, the mol. ratio of the stream to the first gaseous mixture may be from 3:1 to 8:1 and the temperature of the second hydrogen-containing stream is preferably 705-930 DEG  C. to produce a final mixture 65-150 DEG  C. above that of the first mixture.  The final reaction temperature may be 705-930 DEG  C. and the residence time in the hydrodeakylation may be from 1 to 10 seconds.  A suphur compound may be added to the reaction system in an amount 100-300 p.p.m. per mol. of alkyl aromatic hydrocarbon. A quenching gas may be used to control the dealkylation.  Benzene is the normal product, but when the feed comprises C9-C11 aromatic hydrocarbons appreciable quantities of xylenes are produced and may be separated before they are demethylated to toluene and thence to benzene.
