Abstract: ABSTRACT      The present invention relates to a speed control and indication system for a mechanical press (2). In order to enable the press to operate at its full running speed on the first cycle thereof after actuation of the clutch (9), the flywheel (6) is driven at a speed higher than the set running speed so that as the mechanical inertia of the drive mechanism will cause the press to slow down to its set running speed. The control circuit modifies the speed control voltage after actuation of the clutch so that the press continues to run at the set speed even after the mechanical inertia is overcome. The signal from the tachometer (24) to the speed meter (28) is modified before actuation of the clutch so that it provides a reading at the set running speed of the press even though the flywheel is running at a nigher speed.  After the clutch is actuated, the true tachometer voltage is fed to the speed meter so that it continues to indicate the true running speed of the press.

Abstract: THERAPY BATH JET NOZZLE ASSEMBLY WITH               PROVISION FOR SHUT-OFF                             ABSTRACT    An adjustable water/air jet nozzle assembly for whirlpool baths and the like and having means for user selected shut-off during operation and means for preventing shut-off back pressure from causing the flow of  water into the air supply pipe which may-otherwise create a safety hazard and detrimentally affect the performance of  the remaining open jet nozzles.  The assembly comprises a novel venturi fitting  having a check valve in the air passage between the air supply pipe and the water/air mixing chamber.  The check valve is open during normal flow operation but blocks off the air passage during shut-off operation to prevent-water backflow.  The assembly also comprises a readily rotatable spring-loaded eyeball nozzle secured between inner and outer flanged cylindrical fittings that thread into the venturi fitting through a bathtub wall opening to secure the assembly to the bathtub wall.

Abstract: ABSTRACT:          "Error correction method for the transfer of blocks of data bits, a device for performing such a method, a decoder for use with such a method, and a device comprising such a decoder"             For an error correction method for the transfer of word-wise arranged data, two word correction codes are used successively, each code acting on a group of words while, therebetween, an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there are provided a modulator and a demodulator (34). Invalid channel words are provided with an invalidity bit in the demodulator.         During the (possibly correcting) reproduction of the data words, the invalidity bits can be used in one of the two error corrections in various ways: a. When too many words of a group of code words invalid, all words of the relevant group are invalidated (112, 114); b. If a word comprising an invalidity bit is not corrected during correction by means of a syndrome variable, all words of the relevant group are invalidated (112, 114); c. If the number of invalidity bits lies within given limits, they act as error locators so that the code is capable of correcting a larger number of words (118).

Abstract: RESISTOR                    Abstract A minimal corrosion resistor structure and deposition technique for superconductive circuits, with mutually protective niobium oxide passiva-tion ring, gold corrosion barrier film and titanium resistive layer.  Niobium has an intrinsic oxide of Nb2O5, which must be removed from a contact area designated by an opening in photoresist; the development process leaves a photoresist overhang.  The corrosion barrier film is deposited through the opening.  The resistive metal layer is deposited over the corrosion barrier film through the same opening.          The gold corrosion barrier film prevents the titanium resistive metal layer from making corrosive contact with the niobium.  The titanium resistive metal layer encapsulates the gold corrosion barrier film to prevent diffusion between the gold and further layers to be deposited subsequently.  It would normally be possible for the titanium to spill over the gold and make corrosive intimate contact with the niobium; a self-alignment technique prevents such contact.  The gold corrosion barrier film is sharply focused to form an area corresponding to the opening in the photoresist.  An unfocused plasma oxidation step, which follows the gold deposition, grows an extrinsic Nb2O5 passivation ring about the gold.  The titanium resistive metal is then deposited with a wider focus than that of the gold corrosion barrier film, through the same opening; the titanium resistive metal layer deposits over the edge of the gold, encapsulating the gold with a diffusion barrier.
