Abstract: ARTICULATED TRACTOR TIRE ILLUMINATION ARRANGEMENT                 ABSTRACT OF THE DISCLOSURE A tire illumination arrangement for an articulated tractor.  The tractor has front and rear sections pivotally connected along an axis of articulation with a source of electric current mounted on one of the sections.  The front and rear sections are each supported by a pair of ground engaging tires, which are mounted on and for rotation with an axle.  In addition, the front section tires each have an inner surface which face opposite sides of the front section. The arrangement utilizes a lighting device which is electri-cally connected to the source of electric current.  The lighting device is mounted on the front section, below and rearward of the front axle.  This arrangement also utilizes a mechanism, interposed in the electrical connection between the lighting device and the source of electric current, to selectively supply the device with a flow of electric current from the source.  When the device receives a flow of electric current from the source, it produces a forwardly oriented pattern of light to illuminate the inner surfaces of the front tires.

Abstract: L'invention concerne une volée d'escalier de type modulaire et auto-portant, constituée par au moins deux paires de montants servant chacune de support à une marche. Chaque montant comprend une plaque latérale verticale pourvue d'un rebord supérieur horizontal, une plaque frontale verticale définissant avec la plaque latérale un dièdre droit, cette plaque frontale étant également pourvue d'un rebord supérieur horizontal définissant avec le rebord de la plaque latérale un L servant de support rigide et stable à une des extrémités de la marche, et une plaquette de fixation prolongeant intégralement la plaque latérale dans le même plan ou dans un plan parallèle à celui de celle-ci. Les montants de chaque paire sont fixés aux montants respectifs de la paire qui lui est immédiatement supérieure ou inférieure par rivetage ou boulonnage des plaquettes de fixation des uns aux plaques latérales des autres grâces à des trous emboutis prévus à cet effet à la fois dans les plaquettes et les plaques latérales des montants. Cette volée d'escalier est particulièrement intéressante du fait de son excellente stabilité latérale due à la présence de la plaque frontale de chacun de ses montants, sur le rebord de laquelle est fixée chaque marche, et du fait de son excellente résistance au poids due à l'emboutissage des trous servant au rivetage ou boulonnage des montants entre eux, cet emboutissage assurant en effet un certain emboîtement des trous les uns dans les autres lors du rivetage ou du boulonnage des montants et ainsi un renforcement accru de leurs liaisons en particulier-contre les risques de cisaillement vertical.

Abstract: TITLE          SELF-SYNCHRONIZATION CIRCUIT FOR A FFSK OR MSK DEMODULATOR                        INVENTORS                      Rudi de Buda Charles E. Jagger ABSTRACT OF THE DISCLOSURE         The self-synchronization circuit splits the incoming sig-nal into two circuit paths where the signals are frequency shifted by a frequency signal equal to the carrier frequency so as to pro-vide an in-phase signal in one circuit path and a quadrature signal in the other circuit path.  The frequency shifting circuit includes at least a controllable oscillator.  The output of a first multi-plier which multiplies the in-phase and quadrature signals, is fed to a clock recovery circuit which determines the clock frequency.          A second multlplier multiplies the output of the first multiplier with the clock recovery circuit output to provide a signal which controls the controllable oscillator.  In addition, a frequency discriminator utilizes the in-phase and quadrature signals to ini-tially coarse control the controllable oscillator frequency.  The frequency shifting signals may be obtained from the controllable oscillator feeding phase shifting circuits, or they may be obtained from a combined circuit including a fixed oscillator with phase shifting circuits together with the controllable oscillator and appropriate mixing circuits.

Abstract: Abstract of the Disclosure The garment pressing apparatus discloses new opera-tional and construction features in the nature of a pair of upper and lower, externally position and logitudinally ex-tending clamping-creasing heads that are carried by supporting frames extending from an end-positions support.  An upper sup-porting frame is cantilevered from the end support and a lower supporting frame is carried by a lower extension of the end sup-port.  Each head is flexibly mounted on an associated frame in such a manner as to enable shape-conformation thereof with re-pect to various shapes and sizes of slack or trouser-like gar-ments to be finished.  A crotch or fly presser head is carried by a short-length cantilever frame and is fluid-motor operated for "in" and "out" pressing movement with respect to an inner fly-pressing head when a garment is being inside-carried on a permeable bag by pairs of creasing-blades in their expanded relation.  Each creasing head has a convoluted or looped pipe system extending therealong and supplied with steam for heating it, and has a longitudinally extending central member and a pair of side-extending clamping elements or blades mounted for "in" and "out" swingable movement along opposite sides of the central member.  Cross-extending fluid motor means is carried by each head and connected to an associated pair of clamping blades for swinging them towards the central member and each into a coop-erating fabric folding-over relation with an associated into-mediately-positioned creasing blade that extends along one inner side of each leg of the garment when the creasing blades are in their expended relation.  Each pair of clamping blades com-pletes the forming of a side crease along legs of the garment after an associated ceasing blade has been withdrawn by in-wardly collapsing the creasing blade assembly.  The clamping heads are adapted to initially apply a seam folding pressure, and after withdrawal of the creasing blades, to apply a greater final, crease-forming pressure of the garment legs.  Upper and lower creasing heads are thus employed to simultaneously form opposite side creases along each garment leg.  The sequence of operations may be effected automatically in a timed relation or manually to provide a complete garment finishing cycle.
