Abstract: A power unit comprises an internal combustion engine adapted for operating with natural induction, supercharged by a turbine-compressor unit receiving the exhaust gases of the engine. The compressor supplies air to the engine through an intake pipe provided with an atmospheric air inlet closed by a check valve in operation under load. The power of the engine is controlled by a power control member movable by an operator between a maximum power position and an idling position. An inlet valve, placed in the air inlet of the compressor and movable between an open position and a closed position, is biased towards closure by the power control member when the latter is moved towards its idling position. A locking member responsive to air pressure at the outlet of the compressor cooperates with said inlet valve to prevent its closing as long as the air pressure at the outlet of the compressor is greater than a predetermined threshold.

Abstract: A method for knitting a garment on a double-cylinder circular knitting machine, comprising the steps of withdrawing the stitch sinkers firstly with only the yarn taken up by the lower cylinder needles, subsequently lowering the upper cylinder needles to pick up the yarn while causing the stitch sinkers to outwardly project and to pick up the yarn taken by the upper cylinder needles, and raising the lower cylinder needles only after the sinkers have been withdrawn. There is also disclosed a double-cylinder circular knitting machine in which the cams for controlling the sinkers have a notch in a position substantially vertically below the lowering cam which controls lowering of the upper cylinder needles to take up the yarn, the notch being arranged before the raising cam controlling raising of the lower cylinder needles for taking up the yarn.

Abstract: A double-cylinder circular knitting machine with latch needles and a device for automatically causing the latches of the needles operating in the upper needle cylinder to open before knitting. The device comprises cams defining a path for the needle-free sliders of the lower needle cylinder which lies constantly all around the cam box at a level corresponding to that at which the tips of the sliders engage the latches of the rib needles to open them. The needle-free sliders are selectively passed into this path and are subsequently returned into the normal knitting path when knitting plain fabric. The arrangement of the continuous path at a constant level all around the needle cylinder allows a more simple configuration of the latchguard cams and less wear and stresses in the needle latches.

Abstract: A double, jacquard-patterned piled fabric is produced on a modified warp-knitting machine having two needle-rows whose needles form needle-pairs. Each needle-pair receives a respective set of pile threads, differing ones of which are at different points in a pattern to become patterning pile threads visible in the fabric's pile pattern. When a given pile thread is to be non-patterning, it is tied into one of the two ground fabrics in the form of a walewise-running unlooped thread, and is not knitted into the ground fabric in the form of either half or full loops, in order to greatly reduce the rate of consumption of non-patterning pile thread. When a pile thread is to become a patterning pile thread, it is displaced into the zone intermediate the two needle rows and incorporated into alternate ones of the two ground fabrics in the form of half-loops.

Abstract: Disclosed is an improved knitting machine in which special steps have been taken to provide for close correlation of the operation of the knitting filament in-feed equipment and the knitted fabric out-feed equipment with the speed of the knitting head itself, to produce a more uniform and better quality knitted product, and to reduce the danger of filament or fabric breakage caused by jamming at the knitting head or at one of the pieces of feed equipment. These steps are particularly important in the knitting of wire mesh fabric, because wire filament is less stretchable than most textile filaments and thus less able to compensate for variations in the speed of the various pieces of equipment acting upon it as it passes through the machine. In particular, the filament in-feed equipment, the fabric take-up equipment, and if desired, the fabric take-down equipment, are all driven by power trains which include the knitting head.

The apparatus comprises conduits connected to a die and to a high pressure gas. Valves in the conduits regulate the pressure applied to the blank. A controller receives command signals from a programmer which is programmed with the desired time vs pressure relationship.

Abstract: A method and apparatus for the continuous production of bright copper rod from stock discharged from a continuous casting machine in which an oxide layer formed on the stock during its passage from the continuous casting machine in the atmosphere is subjected to an initial breakage and separation operation by discharging a chemically active liquid at a relatively low pressure against the oxide layer followed by descaling the stock after the initiation of the breakage of the layer by projecting jets of liquid at a relatively high pressure against the stock. The stock which is now free from oxide layer is rolled in a rolling mill in the presence of cooling and lubricating liquid which isolates the stock from the outside atmosphere and allows the formation of rod in the stands of the rolling mill. The rod obtained from the rolling mill is cooled by passage through a duct in counterflow with a cooling liquid such that the rod leaves the duct at a temperature below 80.degree. C.

Abstract: A metal wire or rod is passed between two rolls one inside the other but with offset axes. The larger outer roll which may be ring-shaped has a smooth inside contact surface. The smaller internal roll has a smooth outside contact surface. Together, these two eccentrically disposed surfaces form a long converging throat between them through which the wire or rod is passed as it is being rolled into a strip. The opposing, smooth surfaces have a separation at the closest point which is less than 1/3 the diameter of the metal wire or rod to be fed between them. The distance between the point where the wire first contacts the opposing, smooth contact surfaces of the converging throat and the closest point of separation between the opposing surfaces is preferred to be at least four times the original diameter "D" of the wire or rod being fed therethrough.

Abstract: Sheet metal is processed by providing one or more corrugations longitudinally along the sheet in a position spaced from both lateral edges of the sheet while the lateral edges are maintained in fixed relationship to each other, thereby causing the sheet metal portion containing the corrugations to be stretched. The corrugated portion is subsequently rolled or otherwise pressed to flatten out the corrugations either partially or completely, resulting in a sheet which is wider than the original, but which still has certain areas having the original thickness. The sheet metal thus processed may be utilized to form structural members such as channels or studs which are less expensive for a given size than conventional structural members, but which still exhibit sufficient supportive strength by virtue of the portions thereof which retain their original thickness.

Abstract: Improved zircaloy tubes for PWR reactors are produced by a method and apparatus by controlling spirality, that is, the spiral formation of the wall-thickness eccentricity. In the past, that spiral formation has caused the tubes to bow during use, and the present invention permits the maintenance of that spiral formation to acceptable limits. The hollow or workpiece is positioned upon a cylindrical mandrel and is advanced step-by-step through a work zone between a pair of rolls having grooves which define the work zone. The workpiece is turned through a predetermined angle on the mandrel prior to each rocking cycle. The present invention involves controlling the angle at which the metal working forces are exerted so as to minimize the turning moment or torque effect which results in producing the spiral formation.

Abstract: A control for controlling load on a tire undergoing testing while rotating in a loaded condition against a test road wheel. As the tire temperature increases during the warm up period of the tire and inflation pressure and load consequently also increase, the control will automatically decrease the load applied to the tire to maintain a preset load on the tire. During equilibrium temperature and pressure conditions of the tire, the control will effectuate decreases in load only and will not permit the tire load applicator to oscillate the load about the reset load point. The load applicator is maintained in an inactive condition by the control means except when a load decrease is necessary. During equilibrium temperature and load conditions on the tire, a relatively fast increase in temperature and a correspondingly fast load increase indicating incipient failure of the tire can be detected by the control.

Abstract: The determination of a "composite" parameter of the formation water in formations surrounding a borehole, for example the composite conductivity of the formation water, is used in the disclosure to obtain a relatively accurate determination of formation characteristics, such as water saturation. The determined values are meaningful even in shaly regions of the formations. In contrast to past approaches which attempted to determine the volume and distribution type of shale or clay present in the formations and then introduce appropriate factors which often involve substantial guesswork, the disclosed technique determines a composite water parameter, for example a composite water conductivity, which represents the conductivity of the bulk water in the formations, including both free water and bound water. Bound water trapped in shales is accounted for in this determination so unlike prior techniques, the shales can be considered as having a porosity.

The apparatus includes a fluid path system which conducts the expired air to a first fluid detector which produces a first signal operable as a function of concentration for the selected fluid constituent. The signal registered by the detector is used for later comparison with a second signal which provides the basis for determining the expiration rate of fluid constituent originally present in the expired air. To make this determination, the fluid constituent is removed from the expired air, with the expired air being advanced to a mixing chamber where a second detection means senses the fluid concentration.

Abstract: The temperature of an environment is determined by measuring the acoustical response of a temperature sensitive two mode resonator placed in the environment. Two variable frequency signals are generated and applied to the resonator, and the two resonant frequencies of the resonator are determined. Frequency difference of the two frequencies is determined, and if the difference lies within a substantially uniform frequency range, the environment temperature is calculated from at least one of the frequencies. If the difference lies outside of the substantially uniform frequency range, then at least one of the two signals is spurious and no temperature calculation is made.

Performance is assessed in terms of swing time, stance time, overlap time, airborne time and combinations thereof. A method is disclosed of relating measurements of the gait taken at an arbitrary speed to a standard reference speed for purposes of comparing different individuals.

Abstract: A hand tool comprising two moving parts; a rotating and a reciprocating part. The reciprocating part, carrying a machining tool, is imparted its movement from the rotating part via a crank mechanism with variable excentricity for adjusting the reciprocating part's length of stroke. A crank pin in said mechanism is therefore excentrically disposed on a rotatable, lockable slide excentrically journalled in a rotatable holder which is imparted its rotary movement from the drive means of the hand tool. Counterweights in the slide and its holder together counterbalance the movements of the reciprocating part corresponding to the varying lengths of stroke. Upon setting of the crank mechanism to the desired length of stroke, the counterweights are arranged to either work in conjunction or in opposition and are therefore rotatable relative each other to an extent corresponding to the relative movements of the slide and slide holder.

Abstract: An infinitely variable speed, power transmission unit and method in which three torque responsive bodies are shifted between driving, reaction and driven functions to effect alternate modes of operation in which two or more contiguous ranges of infinitely variable speed ratios are provided at high power transmitting efficiencies. Two of the three bodies establish a variable traction surface radius factor by which speed ratio is made infinitely or continuously variable in the range of each mode. The radius ratio factor is related to the gear ratio factor of alternately operable unit gearing in a way to enable the speed ratio range in one mode of operation to be an extension of the other mode. The unit enables synchronous shifting between operating modes in the sense that the radius ratio factor is varied in alternate directions between minimum and maximum values in any two of the respective alternate modes of operation.
