Title: Improvement in coil spring couplings
IPC: F16D3/62
Filed: 1926-09-17
Abstract: 279,221. Siegenthaler, E. R. Sept. 17, 1926. Addition to 239,729. Universal joints.-Resilient buffers are applied to the helical-spring coupling claimed in the parent Specification to limit the spring stress and provide an auxiliary cushioned drive under heavy load. Recessed rubber buffers G are secured on platforms D by holders F, the stems E of which are passed through slots in the buffers and are attached, together with the platforms D to the coupling lugs C, by the same bolts and nuts J, H that rigidly secure the loops of the springs B. The lugs C are formed into covers to conceal the spring connections. Alternatively, a single buffer G may be provided in each spring, with a gap between it and the adjacent lug, or the buffers may be tubular and enclose the springs. In a further modification, the spring wire is sheathed with and vulcanized to a rubber coating.

Patent GB-494371-A (GB)
Title: Arrangements in rectifiers, connected in m n-phase groups with interphase transformer, for eliminating the rise of voltage at low load
IPC: H02H7/127
Filed: 1937-08-24
Abstract: 494,371. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 24, 1937, No. 23213. Convention date, Aug. 29, 1936. [Class 38 (ii)] In a rectifier arrangement having an interphase transformer means are provided responsive to the change in conductive period of the anodes due to reduction of load beyond a certain limit to cut out certain of the anodes. This eliminates the rise of voltage due to the interphase transformer becoming ineffective. In the form shown anodes 1 are in two groups fed from secondary windings interconnected through an interphase transformer 2. The grids of the two groups are controlled from windings 4, 5 and form " floating grid " systems. One group 5 is connected through a very high resistance 9 to a potentiometer 8. In normal. operation (i.e. double three phase) the grid system 5 operates effectively as a floating grid system. If however due to reduction of load the operation changes from double three phase to six phase due to the interphase transformer becoming ineffective, all the anodes associated with the grid system 5 will be periodically simultaneously nonconductive so that the floating grid system loses control and the negative bias from the resistance 8 becomes effective to block the group of anodes. To effect restarting of the group when the load again increases a bias across a resistance 10 is supplied from a current transformer 16 in the load circuit through a transformer 11 and rectifier 13. In a modification, a relay between the neutral lead of the secondary supplying one group of anodes and the interphase transformer remains closed as long as current flows continuously but as soon as the current becomes intermittent due to sixphase operation, opens and negatively biasses the grids to put the group out of operation, or controls a circuit breaker which cuts out the group of anodes. In a further modification, the anodes of at least one in-phase group are arranged in a separate vessel and made to depend on the continuous conduction for their continuous ignition.

Abstract: 890,098. Packaging. HESSER, MASCHINENFABRIK A.G., FR. July 6, 1960 [Aug. 3, 1959], No. 23626/60. Class 94(1). A packaging machine for forming dished containers from thermoplastic foil, for filling the containers and securing separate flat covers thereto, comprises an endless conveyer with upper and lower runs arranged one above the other, there being die-forming clamping means mounted on the conveyer, means for forming the containers along the lower run of the conveyer, and means for filling and closing the containers along the upper run of the conveyer. The conveyer 1 carries a series of jaw like clamping frames 4 that are open at the commencement of the lower run to accept the thermoplastic foil in sheet or web form. The frames 4 then close and pass beneath a radiant heater 18 where the foil is softened. Beneath the conveyer 1 is a further endless conveyer carrying a series of plungers 20 that are raised by cam means 28 to pass through the frames 4 to bulge out the plasticised foil and shape it into containers. The plungers 20 are apertured and connected to a suction source 31 to assist the shaping of the containers. As the plungers 20 withdraw, the shaped containers are hardened beneath a hood 35 that draws off warm air or admits cool air. The containers in the closed frames are filled by an automatic device 32 or by hand, whilst the frames move along the upper run. After the filling operation the frames 4 open temporarily whilst the container covers are placed in position whereafter the frames close, as at 34, to clamp the covers to the containers and to act as high frequency electrodes to seal the covers in position. The jaws 4a, 4b, then open and the sealed containers are discharged down a shoot 37 to a conveyer belt 38. The thermoplastic foil for the containers may be fed as a web from a roll 40 and a web for the covers may be supplied in a similar manner, the webs being cut by knives mounted on the frame components 4a, 4b, or by a cutting device shortly before discharge from the machine. Alternatively, tongs 15, Fig. 2 (not shown), rotating in a horizontal plane pick up foil. blanks severed from a web and place them in the machine at the appropriate points for use as containers and covers. Interchangeable frame-like members are housed in the jaws 4a, 4b.
