  • Patent number: 4580381
    Abstract: Angular sections form frames which can be fitted together in the frame plane in modular fashion. Legs of the sections are formed so that through two interconnected legs of adjacent frames notches of T-shaped cross-section result, into which hammer head-shaped ends of pull rods can be introduced. By means of the pull rods, ledges can be pressed against filter and/or light fixture housings, which in this manner are pressed against legs of the profiles on the opposite housing side, adjacent frames thus make it possible in a correspondingly compact model to attach filters and light fixtures without the distance between two adjacent filters or between a filter and a light fixture occupying a width that would impair the flow profile of the air issuing from the filters.

  • Patent number: 4568226
    Abstract: In known deep-hole drilling machines, the undesirable situation arises, in the case of large drilling depths, that the boring bar, which becomes increasingly softer with increasing drilling depth, sags and starts to vibrate, so that the boring bar must be supported. This should, however, be possible at suitable spacings in the simplest possible manner and without interrupting the working process. For this purpose, it is envisaged that at least one guide bush for supporting the boring bar in a workpiece bore is provided on the boring bar, the guide bush being associated in a coaxial arrangement with a clamping ring of a ringe thickness which makes self-jamming tilting on the boring bar possible, and which clamping ring is pivotally coupled at one peripheral point to the guide bush to permit a small radial movement and has an external diameter smaller than that of the guide bush, and that at least one disengageable stopping device for a guide bush is provided within the coolant feed device.

  • Patent number: 4561954
    Abstract: A method of terminating a multilayer ceramic capacitors and like electronic components is disclosed. In accordance with the method the capacitors are loaded into apertures formed in an elastomeric mask such that only the surface portions to be metalized are exposed. In advance of loading, the surfaces of the mask are pre-coated, preferably by a sputtering procedure, so as to preclude "out-gasing" of the mask material during sputtering.

  • Patent number: 4544599
    Abstract: The present invention relates to a method for producing elastically deformable articles constituted of a textile substrate of carbon fibers which are elastically deformable with respect to an at rest shape, wherein a flexible structure of carbon fibers is used, a predetermined form being set for this textile by means of shaping tools, and said textile being retained in said at rest shape by forming around the said fibers a thin coating of rough laminar pyrolytic carbon deposited by chemical vapor infiltration at high temperature without bonding of the fibers one to another. The textile can be given a flat form by using holding plates. It is possible to start from a braided sleeve which is either compressed or stretched axially around a mandrel. It is also possible to use a woven tape which is wound in a conical pseudo-spiral for use as a cardiac valve.

  • Patent number: 4539740
    Abstract: The present invention relates to an apparatus and method for rapidly and accurately inserting axial lead components such as capacitors and resistors or the like into printed circuit boards mounted in an X-Y PC board positioning device. In accordance with the invention a plurality of magazines each of which contain a multiplicity of the components are loaded into a receiver chute of the apparatus. The apparatus functions, responsive to a signal from the PC positioning device, to remove an individual component from a magazine, deflect the leads to a position at right angles to the body of the component and insert the thus formed leads accurately into spaced apertures of the PC board which have been maneuvered by the X-Y apparatus to a component receiver station. The device includes means for automatically removing exhausted magazines and replacing the same with filled magazines.

  • Patent number: 4539831
    Abstract: A crankshaft rolling machine includes a pair of model crankshafts mounted for synchronous rotation. One or more crankshaft rolling units are coupled to the model crankshafts in a manner enabling adjustment of the units along a linear path to adapt the device to the stroke length of a crankshaft to be rolled. The apparatus may be rapidly changed for rolling of crankshafts having different stroke lengths by linearly sliding the individual rolling units relative to the model cranks and thereafter locking the individual rolling units to the model cranks at positions corresponding with the stroke length of the crankshaft to be rolled.

  • Patent number: 4527185
    Abstract: The present invention relates to an integrated circuit device particularly of the type carrying multiple memory circuits or the like. The device incorporates a lead frame of the sort which includes an elongate metallic web and is characterized by the lead frame providing an integral seat or platform whereon is mounted a capacitor device which is connected or adapted to be connected in shunting relation of the power supply inputs to the integrated circuit device, whereby the capacitor provides a convenient mounting platform for the circuit bearing elements and also assures minimal lead lengths between the capacitor and the power supply inputs of the circuit bearing chip. Due to the shortness of such lead lengths and consequent reduction of the inductance reactance of the power supply circuit, efficient dampening of switching transients is achieved with the use of capacitors of much smaller values, in less area than heretofore required in external dampening applications.

  • Patent number: 4510664
    Abstract: In order to produce a packing ring having a stiffening ring by a method which dispenses with the use of a complicated and expensive mold, an extrusion having the desired cross-section of the packing ring and having a cavity, extending in the extrusion direction, for the reception of the stiffening ring is firstly produced. The extruded material cut to length in accordance with the desired circumference of the packing ring is slipped onto a wire which is similarly cut to length and bent into a circle. The ends of the extruded material are pushed back while the ends of the wire are welded together, so that a closed stiffening ring is produced. Then the material ends are joined together and are bonded or vulcanized to one another.

  • Patent number: 4506431
    Abstract: Method of manufacturing an accumulator device including a shell portion having an open mouth and a cap member affixed over the open mouth after a bladder assembly has been secured within the shell portion of the pressure vessel. The method comprises in the provision of an exterior annular weld connecting the cap member to the outer wall portion of the vessel as well as an interior weld connection between the interior wall portion of the cap member and the upwardly directed end edge of the mouth of the pressure vessel. By locating the metallic skirt member which functions to support the bladder such that the top of the skirt forms a dam for containing the weld which secures the cap member interior to the uppermost edge of the pressure vessel, the possibility of weld fragments falling into the bladder causing damage to the latter is minimized.
