Abstract: Abstract of the Disclosure In a MIG arc welding system, a docking body having utilities passages therethrough is mountable at the welding station.  Means are provided at one end of the body for accepting incoming utilities such as consumable wire electrode, shielding gas, welding potential and cooling water.  Different types of welding gun or torch assemblies are interchangeably manually mountable and demountable at the other end of the welding body without disturbing the docking body or the utilities coupled thereto.  Plug-type water fittings on the welding gun or torch assembly are receivable in receptacles in the docking body which communicate with the water passages, actuator tips on the fittings actuating normally-closed, spring-biased check valves in the passages to prevent leakage of water from the docking body when the welding gun or torch assembly is demounted.  The gun or torch assembly is held in place by a coupling nut which is threadedly engaged with the docking body.  There are provided a fixed-mount embodiment, wherein all utilities but the welding wire enter the docking body radially, and a remote or movable mount embodiment, suitable for mounting on a movable mechanized or robotic support, wherein all utilities enter the docking body axially.  A positioning ring on the latter embodiment accurately positions the docking body on the movable support.

Abstract: ABSTRACT DISPLAY TUBE    In a display tube comprising an envelope (10) having parallel front and rear walls (12 and 14) containing implosion-preventing support walls (22) dividing the envelope into a plurality of modules, each module includes a low current electron emitter (24), for example a thermionic wire emitter, a switching electrode arrangement (25) comprising a plurality of electrode-carrying layers each having a plurality of apertures spaced in a row vertically of the module which apertures serve to define one of a plurality of electron beam paths directed towards a cathodoluminescent screen carried on the front wall (12), and a channel electron multiplier intermediate the switching electrode arrangement (25) and the screen for beam current multiplication.  The switching electrode arrangement comprises a stack of mutually insulated electrodes associated with each aperture selectively operable to allow or prevent electron  to pass therethrough thereby to effect frame scanning, line scanning and electron acceleration being achieved by means of electrodes (32, 34, 36) carried by the support walls (22).

Abstract: ABSTRACT OF THE DISCLOSURE          Capacitive sensors (A, B, C,) are attached to the closing edges of especially automatically controlled elevator doors, which (sen-sors) produce error signals ( .DELTA. U) by way of differential ampli-fiers (1, 2) if their antennas A, B, C,) are capacity influenced by an obstacle or a disturbance.  A door travel detector (25), which senses (or scans) the entire door region in incremental travel dis-tances ( .DELTA. S) of, for instance, 1 cm in fine steps respectively quasi-steadily, controls by way of the pulse generator (26) the compensators (3, 4,), which consist  of the threshold value detector (18, 22), forward-/reverse counter (19, 23) and digital-/analog con-verter (:20, 24).  Every error signal ( .DELTA. U) is subjected to a com-pensation at every door movement piece by piece (?) for every travel distance (S) and the determined compensation value per travel dis-tance ( .DELTA. S) and per floor stored in the incremental balancing storage (16, 17) and corrected at the next compensation cycle.  In this the compensation maximally attainable per travel distance ( .DELTA. S) is chosen in such a manner that it is hardly of great importance for rapidly variable obstacle signals caused by persons or objects, while slowly variable error signals, due to, for instance, mechani-cal tolerences or temperature variations, are reduced to a minimal residual amplitude.  For this reason obstacle signals will prevent, stop or reverse a door closing movement by way of the majority gate (15), the evaluating circuit (5) and the door circuits (30, 31, 32, 33, 34, 35) while error signals remain ineffective with regard to door control.

Title: Ice cream dispenser - with a system for automatically controlling the viscosity or time mix
IPC: A23G9/22
Filed: 1971-06-23
Abstract: The refrigerated mixing chamber has its spiral screw driven through a belt drive by an electric motor whose speed is controlled by a rotary shell around the outside. When the consistency of the mixt. becomes thin, and the speed rises, this shell rotates through a part of an arc of a circle, moving an arm with a rod hinged onto its end against a spring to operate a switch which closes the refrigerator circuit. The mixture then thickens until the speed drops and the switch is opened by the spring. Thus the consistency is maintained automatically.

IPC: B04B5/12
Filed: 1984-04-19
Abstract: A continuous flow device is disclosed for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the usual commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of lesser density caused by a thickened slurry layer. A thin film of a slurry of solid particles of differing size and density travels over a revolving surface (20) of such configuration that the slurry flows in a substantially laminar manner. As the thin film of slurry flows along the surface, the particles of greater density tend to concentrate in the region next to the surface (20), while the particles of lesser density remain in or are forced into the fraction of the film closestto the axis of revolution (14). Before the film of slurry reachs the end (24) of the flow path it is passed over a splitting device (21) to separate the fraction of the film containing particles of greater density from the fraction containing particles of lesser density.

Abstract: For manufacturing approximately hexagonal coils for the rotors of electrical machines, conductor assemblies must be bent into the desired shape. In this case, curvature in the spatial direction is also required as well as the special contour. Until now, such conductor assemblies have been bent either purely manually, by matching them to a template, or also mechanically, by means of separate work processes in which the contour of the conductor strands was produced first followed by the spatial curvature. According to the invention, the individual bending processes are carried out about different spatial axes within the course of a single handling of the conductor assembly. In the associated device, with a U-shaped end of a rod clamped in a retaining device, stop parts (110, 120, 130, 140, 150, 160) are provided as a boundary of the templates for the conductor strands (10; 11 to 16), to which stop parts there is allocated in each case one bending head (210, 220, 230) with moving bending fingers (215, 225). <IMAGE>

Abstract: The bleach chemicals 8 are added immediately after heating 4 of the over 20%-by-weight thickened fibre material, immediately before mixing of the material. The mixing is carried out in a fast-running short-time- intensive mixer, preferably in dispersion equipment 11, in which the material is forced through several narrow slits in the dispersion apparatus and thereby subjected to strong cutting, impact and kneading forces. The mixing process is reduced thereby to under 3 seconds, if possible to one second. This cuts down a dithionite bleach to less than 15 minutes, and thereby makes unnecessary any steps to remove air from the reaction. The procedure can be utilized with advantage for a peroxide bleach, which can also be appreciably shortened. It is preferable to operate with a heat-dispersion temperature of 95 degree C. In this way two operations are effected simultaneously: bleaching and dispersion; and thereby a separate dispersion stage and larger reaction towers and pumps are eliminated. <IMAGE>
