Title: Process for improvement the heat exchange in a latent heat store, and apparatus for performing the process
IPC: F28F23/02
Filed: 1980-04-08
Abstract: In a process for achieving heat exchange in a latent heat store 10, between a heat storage medium 14 and a heat vehicle medium 37, by way of a heat transfer surface 30 separating the two media, the heat storage medium 14 (e.g. a grit) is brought into a fluidized state by a fluidizing medium e.g. a paraffin oil 16 (or air or an inert gas, Fig. 3) which is substantially immiscible with the heat storage medium. A temperature sensor 39 may control a pump 20 to regulate the degree of fluidization. The heat vehicle medium 37 may be a water-glycol mixture circulated through a solar heat collector 36 or through the evaporator of a heat pump (e.g. 56, Fig. 2). The heat store 10 may provide heat for a heating or hot water system (e.g. via a circuit 40, 42, 44). Supplementary heat for the heat store may be provided by an electric heater 48 or by an oil burner (.e.g. 70, Fig. 2) in the circuit 40, 42, 44.

Title: Two-for-one spinning or twisting spindle having a compressed-air-operated threading arrangement
IPC: D01H7/86
Filed: 1980-06-27
Abstract: There is described a two-for-one spinning or twisting spindle in which thread drawn from a take-up package is threaded through from the bottom upwards by means of a compressed-air-operated threading arrangement so that it can be connected to thread, coming from a supply package, at the top end of a thread entry tube. In the arrangement shown, a thread storage disc of a two-for-one twisting spindle has therein a thread exit passage 8 the inner end of which opens into a short tube 10 which opens in turn into a hollow shaft 12 of the spindle, leaving an annular gap 11. In operation of the threading arrangement, compressed air is fed into a hollow shank 5 of the spindle from below and flows upwards through the annular gap 11. Because of this the short tube 10 acts as an injector nozzle which sucks the thread into the thread exit passage 8 from the side and transports it upwards through the hollow shaft 12 of the spindle. The thread can thus be knotted at the top end of the spindle which means that the spindle and take-up bobbin do not need to start up at different times as was previously necessary. In another embodiment, compressed air can be supplied to an injector arrangement through a passage in a floor of a protective pot.

Title: Stocking of Patterned Knitting, Executed by Stitch Transfer (Open- work), with Coloured Design Effects
IPC: D04B9/34
Filed: 1980-07-31
Abstract: A stocking for a certain leg length is of openwork patterned knitting executed by stitch transfer over its entire circumference, and then comprises a leg portion in which the patterned knitting is interrupted in a certain part of the circumference by a zone of plain knitting (C) with coloured design effects (plated), and after this can again be of patterned knitting over its entire circumference. The device for producing the stocking comprises a single cylinder machine with stitch transfer pushers in cylinder slots alternating with the needles. A selection system selects the needles and pushers for controlling the pattern and includes a lever for nullifying the needle and pusher selection in the zone of plain knitting (C). Coloured yarn is fed in and a retractable cam raises the needles to the height of the yarn when knitting the zone C. A second selector system selects the needles and pushers which are not required to take the coloured yarn and makes them inoperative.

Title: Method and device for controlling resonance vibration trough
IPC: B65G27/32
Filed: 1980-09-01
Abstract: The control system keeps the amplitude of vibration of the vibrated mass constant. The vibrations are generated by an unbalanced motor whose speed is controlled to keep the amplitude constant. A signal describing the required amplitude is compared with a signal describing the measured amplitude. The control loop is broken during the start-up of the motor. The speed of the motor is controlled by controlling the supply voltage. The amplitude of the vibration is measured inductively. The voltage supplied to the motor is regulated by a thyristor unit. The required amplitude can be set as required.

Title: Yarn feeder and changer unit
IPC: D04B15/60
Filed: 1980-09-26
Abstract: A yarn feeder and changer unit for a knitting machine comprises a number of adjacent yarn feeders any one of which can be moved from a yarn trapping position to a yarn feeding position while the others retain severed ends of their respective yarns at the trapping positions. The movement of each feeder to its feeding position comprises an upward component of movement from below the needle level by pivotal movement about a horizontal axis, and forward movement over the needles by a sliding component of movement. The creation of two distinct components of movement for each feeder (pivotal and sliding) enables the feeder path to pass close to but out of the path of the needles, and enables accurate yarn placement to be achieved.

Title: Case hardening method for steel parts
IPC: C21D7/04
Filed: 1983-04-21
Abstract: A method of case hardening surfaces of steel parts insures the presence of a relatively high percentage of untempered martensite within a case hardened depth of at least ten thousandths of an inch. The untempered martensite provides for a Rockwell C surface hardness in the range of 59 to 68, and promotes greater resistance to abrasion and deformation. The method also creates compressive stresses in the surface case hardened depth, and thus measurably enhances the fatigue life of the latter surface as a contact bearing member. The method includes the completion of all conventional metal removal operations on the part including finish machining steps prior to heat treatment thereof. In one preferred form, the method includes the steps of (1) completing all machining operations on the part, (2) carburizing the part to achieve a high surface carbon concentration, (3) direct quenching the part in oil by means resulting in retension of 10 to 30 percent austenite in the case hardened depth, (4) time tempering the part and (5) work hardening the part to transform a substantial portion of the retained austenite into untempered martensite, resulting in a case depth having a composition including at least 5 to 20 percent untempered martensite.

Title: Apparatus for mixing and dosing solids.
IPC: B65D88/68
Filed: 1984-07-20
Abstract: The centrally located outlet in the bottom portion of a silo for a flowable solid building material or fertilizer discharges directly into a first chamber of a mixing unit having a vertical shaft which is coaxial with the outlet and rotates one or more first tools in the first chamber to uniformly distribute the inflowing material and to reduce its tendency to become separated into two or more ingredients. The thus pretreated material descends into a second chamber and into the range of one or more rotating second tools which are driven by the shaft and intermix the material with one or more liquids before the finished product enters an evacuating pump which conveys it to one or more locations of use or to further processing units. The utilization of a vertical shaft and of parts which rotate about one or more vertical axes reduces the wear and prolongs the useful life of such moving parts. The housing of the mixing unit is attached directly to the silo and is pivotable to and from a position of register of its first chamber with the outlet.
