Abstract: ABSTRACT OF THE DISCLOSURE         A three-axis actuator assembly comprises pitch, yaw, and roll hydraulic actuators supported indirectly by corresponding brackets in series relation.  Each bracket is supported for rotation about the axis of the prior actuator in the bracket for the prior actuator so that the brackets, rather than the actuators, carry the loads other than torques. The torques reaction forces imposed on each actuator casing are carried by wide thin torque reaction bands connected between the casing and the bracket for that actuator.  Each band has an offset segment located between the actuator and the bracket to accommodate by flexure tolerance variations without imparting any significant side loads to the actuator. The bracket for each actuator includes a manifold plate carry-ing a servovalve that communicates through orifices and couplings with the ports of the actuator.  Anti-backlash coupling assemblies connect the wing shafts of the actuators with the bracket for the next actuator or with the tool holder, in the case of the last actuator.

The shaft of the band spool is likewise brakeable and blockable by means of a jaw brake.  The frame together with the winding core, band spool and the therebetween traveling winding band can be transported.  For winding-up flat products or the like the shaft of the winding core is driven,  and the jaw brake effective upon such shaft is opened or entered.  The band spool is slightly braked by the jaw brake associated with the shaft of the band spool.  The flat products are infed  to a winding gap and together with the winding band which is under tension wound-up upon the winding core.  After formation of the wound product package the winding core and the band spool are blocked by means of their related  jaw brakes. The package is held together by the winding band which is retained under tension.

Abstract: ABSTRACT A double heterostructure semiconductor laser device comprises a multi-layered structure including a semiconductor substrate of one conductivity type, a wide bandgap first layer of the same conductivity type disposed on a major surface of the substrate, a narrower bandgap active region disposed on the first layer, and a wide bandgap second layer of the opposite conductivity type disposed on the active region.  The active region is capable of emitting stimulated radiation when the layers are forward biased. One of the first and second layers forms a periodic structure having a proscribed pitch of thickness in the propagating direction of the radiation.  The multilayered structure has the shape of an elongated mesa, which extends parallel to the propagating direction of the radiation, channelled along both sides thereof to such an extent that two channels reach the first cladding layer.  Wide bandgap third and fourth layers, opposite to each other in conductivity type, are formed on the multilayered structure except for the top surface of the mesa for blocking current flow therethrough.  Electrodes are provided for applying said forward bias.  The structure of the laser is resistant to high temperature operation because the laser is planar which permits the electrodes to be full surface ones.  Also, the active layer is less susceptible to damage or deterioration than where a periodic structure is found after growth of an active layer. Finally as it has only one waveguide path it is free from output photocoupling difficulties.

Abstract: HOT MELT SIZING APPLYING      ABSTRACT          An apparatus and method effect application of molten size to textile yarns, such as spun yarns. An applicator cylinder is rotatable about a horizon-tal axis and has a number of grooves circumferen-tially formed in its surface, with peaked lands between the grooves, each land making an angle of about 8-12° with respect to a plane bridging the top of an associated groove.  A furnisher roll, also rotatable about a horizontal axis, picks up molten size from an open-top trouqh and delivers it to grooves in the rotating applicator cylinder.  The surface of the furnisher roll cooperates with that of the applicator cylinder so that sloping areas of the furnisher roll mate with the lands of the applicator cylinder and so that flat areas of the furnisher roll bridge the entrances to the grooves. The furnisher roll may be of polytetrafluoroethylene machined to correspond to the surface of the applicator cylinder, or may have an elastomeric material surface.  A cleaning device comprises a pad, which may be a thermoplastic polymeric material capable of lengthy exposure to high temperatures, having a surface corresponding essentially identi-cally to the surface of the applicator cylinder, and mounted so that it is pressed into engagement with the applicator cylinder to remove molten size and contaminants from the grooves of the applicator cylinder.  The molten size with contaminants is diverted by the cleaner to a filter, which removes lint from the size and returns it to the trough.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus is provided for warming the window washing liquid of a motor vehicle having a window washing system, which includes a window washer liquid tank, a washer liquid pump, washer liquid hoses and window nozzles.  The apparatus includes an exposed, flexible tube having a generally circular cross-sectional shape, helically wound about, and extended axially along, and at least partially elastically held to, an outer surface of an engine coolant circulatory hose connected between the outlet of the cooling jacket of an engine of the motor vehicle and the inlet to a radiator of the engine by being wound about the engine coolant circulator hose under tension; and coupling means at each end of the exposed flexible tube for connecting the heat exchanger means between the washer liquid tank and the washer liquid hose through which washer liquid flows from the tank to the washer liquid ejecting window nozzles.  This apparatus is simple, inexpensive and can easily be installed.          The apparatus needs little space, because it is installed by winding the flexible heat exchanger tube under tension around the engine coolant circulatory hose.  It also solves the difficulty of securement of parts, which has been a serious problem in the past by the combination of winding the flexible heat exchanger tube under tension around the engine coolant circulatory hose, and the use of a preferred specifically recited additional securing means.
