Abstract: ABSTRACT OF THE DISCLOSURE         A spiral pancake armature winding assembly for a superconducting generator is provided which incorporates inner and outer support tubes along with a middle support tube disposed within the pancake coil assembly itself.  A plurality of filler pieces, each of which is shaped to fit within  a  generally rectangular opening of each pancake coil, are rigidly attached to each other in such a way so as to form a middle support tube which provides mechanical support to the pancake coils and prevents relative circum-ferential  movement between adjacent pancake coils.  The inner and outer support tubes are shaped to fit within the bore of the spiral pancake armature winding and around its outer periphery.  A plurality of spiral wedges, or ramps, are used in conjunction with the inner and outer support tubes in order to provide an improved fit between the support tubes and the spiral pancake armature winding.  An assembly  method  is  described  which  progresses  from  a configuration in which the plurality of pancake coils are loosely arranged in a pinwheel association to the compact spiral  pancake  armature  winding  in which each of  the plurality of pancake coils is in contact with other adja-cent pancake coils.

Abstract: ABSTRACT           The present invention is concerned with a capacitive humidity sensor and a method for the manu-facture of same.  The sensor comprises a substrate, first and second bottom electrodes arranged close to each other on the substrate, and an active layer, which fills the area between the first and the second bottom electrodes on the substrate and extends to above the top face of the second electrode.  According to the invention, the sensor further comprises a plurality of conductive, beam-shaped structures placed side-by-side, connected to the first electrode, and having an upwardly widening cross-section, the structures limit-ing portions of the active layer between themselves from two sides such that a narrow slot is provided between the top faces of the structures.  Owing to its construction, the sensor of the invention is not sensitive to touching.

Abstract: Abstract In order to achieve a constant, virtually optimal tempera-ture of the fuel oil supplied to a burner and prevent any local overheating even when the burner malfunctions or is temporarily switched off, a preheating device for fuel oil to be installed in the fuel supply path is provided which comprises a chamber having an inlet for the oil to be pre-heated, this inlet being directly connected with the central passage of a first heating cartridge arranged within the chamber, and a  second heating cartridge following the first, arranged in a cup-shaped vessel in such a way that a pressure chamber is formed between the bottom of the cup and a front surface of the second heating cartridge, this pressure cham-ber communicating with the inside of the chamber via a narrow annular gap extending along the length of the second heating cartridge between the outer walling of this cartridge and the inner walling of the cup-shaped vessel.  An immersion pipe leads from the central passage of the first heating cartridge to the vicinity of a closed end of the central passage of the second heating cartridge.  Due to the specially designed path of flow, heat transmission from the heating cartridges to the fuel oil is good.

Abstract: A B S T R A C T       Process for manufacturing synthetic decorative coverings in which at least one powder is deposited loc-ally, according to a pattern or decoration, on a base.       The deposition is carried out under gravity with a continuous screen printing frame in the absence of con-tact between the means of applying the powder and the base, at least one of the deposited powders containing particles which are fusible at a temperature below the dis-tortion temperature of the base and which are of a nature compatible with that of the base or at least close to the said temperature.  At least one thermal treatment is then carried out at a temperature below the distortion temperature of the base, with a view to fixing the deco-ration produced by depositing powders.       The means for applying the powders consist of a screen printing roll (10) fed by a device for uniform distribution of the powder in a hopper (14) inside the roll, whose two longitudinal lips are separated by an adjustable distance and are in contact with the inner surface of the screen.

Abstract: IMPROVED PROCESS FOR THE  PRODUCTION OF OXIDES                     ABSTRACT         Alkene oxide can be made in a simple, closed process that uses electrolysis to make bromine and hydroxide from bromide and water.  The alkene reacts with bromine and then water to form an alkene bromohydrin, which is dehydrobrominated by hydroxide, regenerating bromide, to give alkene oxide.        The main by-product in propylene oxide production is 1,2-dibromopropane, made by propylene reacting with bromine and then bromide.  Since formation of 1,2-dibromopropane consumes propylene, electrical power, and bromide, which must be recovered, it is desirable to minimize its formation.        It has been discovered that adding carbonate and/or bicarbonate to the bromide electrolyte reduces the formation of 1,2-dibromopropane independently of any pH effect.        Carbonate/bicarbonate can be used to reduce formation of dibromo-compounds produced in epoxidation of other alkenes using the electrobromohydrin process.        Other carboxylic materials, which are functionally similar to bicarbonate, can also reduce formation of dibromo-compounds, as demonstrated using ethylene diamine tetraacetic acid disodium salt to reduce formation of 1,2-dibromopropane in propylene oxide production.

Abstract: POSITION SENSOR                 ABSTRACT OF THE DISCLOSURE        A position sensor has a detector having a plurality of sensitive elements which are acted on by indicia of a scale so that each sensitive element detects overlap between itself and one or more indicia of the scale.  The outputs of the sensitive elements are modified by weighting values so that there is one position of detector and scale where the sum of the outputs has a unique characteristic.  This posi-tion can be detected by means analyzing the sum of the out-puts, and can then detect displacement of scale and detector from that one position.  The indicia used have a non-uniform pattern, but other indicia with a pitch less than twice but not equal to the pitch of the sensitive elements may be pro-vided to permit interpolation to fractions of the pitch of the sensitive elements.  Further interpolation may be provided by a register through which signals propagate at a rate which is a multiple of the rate they are received.  The register elements modify the signals by weighting values and the sum of the register element outputs is determined.

Abstract: SPECIFICATION            TO ALL WHOM IT MAY CONCERN:           Be it known that I, AUSTIN TIMOTHY RYAN, a citizen of the Commonwealth of Australia, residing at 19 Hewitt Street, Warracknabeal 3393, in the State of Victoria, Commonwealth of Australia r have invented certain new and useful improvements in and relating to "MOUNTING          OF PLOUGHSHARES" of which the following is a specification.     ABSTRACT OF THE DISCLOSURE            A ploughshare assembly includes a ploughshare and a support for the ploughshare.  A pair of opposed internal edges defines a recess in the ploughshare.  A holder formation on the support includes a foot portion and a pair of grooves adjacent the foot to receive the aforesaid internal edges of the ploughshare so that when the ploughshare is in its working position on the support the foot engages under the ploughshare and retains it in place.  An aperture in the ploughspare behind the internal edges is wider than the separation of the edges and is dimensioned to pass the foot when the ploughshare is sufficiently rotated relative to the support and so allow detachment of the ploughshare from the support.  Resilient latch means detachably mounted to the support is releasably positionable to engage a detent face on the ploughshare to prevent excessive forward movement of the ploughshare with respect to the support.  The support has a forward face which is divided at a ridge into a pair of surfaces which trail rearwardly outwardly from the ridge. The ridge and surfaces serve to divide the material stream thrown up by the share and substantially smoothly deflecting this stream over the surfaces and past the support.          An embodiment of ploughshare is of broadly triangular configuration and comprises a body portion and a pair of convergent replaceable marginal strips which are secured to the body portion and define respective forward ground working edges.
