Patent GB-286762-A (GB)
Title: Improvements relating to dynamo-electric machines for converting electric currents
IPC: H02K47/18
Filed: 1926-12-03
Abstract: 286,762. Quasi-Arc Co., Ltd., and Musto, R. J. Dec 3, 1926. Rotary transformers. - An alternating - current dynamoelectric welding set comprises two machines or two machine elements of the induction motor type both supplied from a polyphase source, one acting as a transformer and the other as a motor driving the rotor of the transformer; the transformer has a single-phase output winding for supplying welding current and the electrical constants of the set are such that the output frequency is greater than that of the source of supply while the input phases of the transformer take a substantially balanced current. In a modification, the dynamo-electric welding set has a polyphase output winding supplying independent welding units which give rise to unbalanced output conditions whilst balanced currents are maintained in the phases of the input winding. In the arrangement shown in Fig. 1, the set comprises a motor Q having a three-phase two-pole primary winding 7 and a squirrel cage rotor 8, driving a transformer having a three-phase 4-pole primary winding 1 on the rotor connected to slip-rings 4 and a single-phase output winding 2 on the stator. Both primary windings are fed in parallel from a three-phase source 3. The welding arc 5 is connected to the winding 2 through an adjustable choking coil 6. The rotor 8 revolves in the same direction as the rotating field produced by the winding 1 so that the frequency in the ouput. winding 2 is three times that of the source of supply. In the modification shown in Fig. 2, the motor Q is provided with a wound rotor, the winding 10 being connected through slip-rings 11 to a throw-over switch 12, whereby the winding can be connected either to a starter 13 or to brushes 14 resting on a commutator 15 connected to a phase compensating winding 16. Fig. 3 shows the invention applied to multiple-arc welding. The output winding 2 of the transformer has three phases and feeds welding arcs 5<a>, 5<b>, 5<c> through adjustable choking coils 6<a>, 6<b>, 6<c>. The compensating winding in this case is connected to the secondary winding 2 of the transformer and has the additional effect of tending to maintain the output voltage upon increase of load current. In order to produce a sinusoidal flux distribution, the coils of the transformer primary winding are caused to overlap and the slots may be skewed by one slot pitch. The coils of the transformer secondary winding may embrace more or less than a complete pole pitch and the winding should have a high inductance except when connected to a compensating winding as in Fig. 3. The motor and transformer may constitute separate machines or both may be incorporated in one machine and the stator and rotor windings of each element may be interchanged.

Title: Improvements in or relating to esters of beta-hydroxy carboxylic acids and method ofpreparing same
IPC: C07C69/675
Filed: 1948-11-29
Abstract: Esters of the formula <FORM:0654561/IV (b)/1> where Ar is an aryl hydrocarbon radical, R is hydrogen or an alkyl, aryl or cycloalkyl radical having 1 to 6 carbon atoms and n is 0 or 1, are prepared by reacting a phenol ArOH with a beta-lactone of the formula <FORM:0654561/IV (b)/2> in the presence of a strong mineral acid. The compounds where n is 0 are found initially and these condense on further heating with the acid to give the esters where n = 1; thus a short reaction time favours the production of the first type and a long reaction time the second type.  The catalyst may be sulphuric, hydrochloric or phosphoric acid in amounts of 0.2-4 per cent of the lactone, preferably 1 per cent.  An inert solvent or water may be used, if desired, and the phenol is preferably used in excess of the theoretical quantity.  The reaction temperature may vary between 0 DEG  and 100 DEG  C., preferably 30-70 DEG  C.  At the end of the reaction, a basic substance is added to neutralize the catalyst, excess phenol removed, e.g. by distillation, lactone polymer removed by filtration and the residue extracted, if desired, with an organic solvent.  The products are separated by fractional distillation. Specified phenols are phenol itself, cresols, xylenols, hydroxystyrenes, cumenol, naphthols, monohydroxydiphenyls, monohydroxy - anthracenes and monohydroxy-di- and tri-phenylmethanes. Specified lactones are b  - propiolactone, b  - butyrolactone, b  - isobutyrolactone, b  - valero-lactone, b  - isovalerolactone, b  - n - capro-lactone, a  - ethyl - b  - propiolactone, a  - isopropyl - b - propiolactone, a  - n - butyl - b  propiolactone a  - methyl - b  - butyrolactone, a  - ethyl - b  - butyrolactone, b  - cyclohexyl - b - propiolactone and a -phenyl-b -propiolactone. Examples show the reaction of b -propiolactone with phenol and the three cresols and of b -butyrolactone with phenol.

Patent GB-1560212-A (GB)
Title: Door
IPC: B65D90/00
Filed: 1977-07-25
Abstract: A cargo container door construction is disclosed. The construction utilizes a relatively thin sheet metal door skin having a plurality of formed-in longitudinally extending stiffener grooves, with the door edge parallel to the grooves being formed into stiffener edges comprising a lip with a recess on its inner side. One such edge supports hinges which connect with a surrounding frame of a cargo container. The two remaining edges of each door lying perpendicular to the grooves, are each stiffened by an elongated bar and plate which are welded continuously to the edge of the skin and which form closed end walls on the grooves. The bar and plate establish edges which are similar to the lip and recess formed edges and the sides of the door, so that a uniform peripheral edge results. The lip and recess at each edge seat a gasket for sealing the door or pair of doors with a cargo container frame. Longitudinally-extending locking bars, which engage with the container frame, are mounted near the stiffener grooves to withstand closure stresses.

The winding of thread from the inside of a yarn holder in a centrifugal spinning or twisting machine on to a bobbin carried by the thread guide is initiated by allowing the thread guide to fall freely. During the fall, turns of thread are wound on the bobbin. The cardboard bobbin or tube 3 is carried on the thread guide 2 which may be uncoupled from an element 4 of the traverse mechanism by a hand lever 1 so that the guide 2 and tube 3 fall freely. When all the thread has been transferred, the guide 2 is raised until held by a hook 6 whereupon the full bobbin may be replaced by an empty one; pressure on a knob 7 allows the guide 2 to fall to operative position. The hand levers 1 of a group of thread holders 5 may be operated by a common rod 8. Specifications 845,883, 845,885 and 845,888 are referred to.
