The first and second structures are interconnected by at least two horizontal connecting rods. Display panels or sheets are connected between the first and second structures.

Abstract: The cassette tape recorder for the four common types of cassettes according to German Industrial Standards DIN 32 715 T, 32 715 W, and the so-called micro-cassette as well as the mini-M-cassette comprises three sound head carriers (10, 20, 30) adapted to be moved selectively into operating position. Furthermore, the spacing between winding shafts (2,2') is adjustable by a movable cam disc (17). This adjustment is taken care of by cam disc engaging fixtures (23, 33) at the movable sound head carriers (20 and 30, respectively) and by a spring (18) holding the cam disc (17) in an inoperative position against a stop. Likewise provided are adjustable winding heads (3,3') causing different engagement members (4,6) to become effective for the winding drive, the adjustment of the winding heads (3,3') also being effected upon moving of the sound head carriers (10,20,30).

The invention method comprises the steps of forming either the retaining member or the body member by injection molding a first synthetic resin; and forming the other member on the first molded member by injection molding a second synthetic resin which is different in kind from and nonconjunctive to the first synthetic resin so as to obtain an assembly of the retaining member and the body member.

Abstract: A method and apparatus for locating the position of parts, and identifying hanges in parts position over time, within a radioactive cell by utilizing two cameras mounted on a stationary positioning table within the cell, each of the cameras being capable of relative displacement on the table under control of a computer, and each camera having a high resolution objective field smaller than the total desired viewing field. The method is implemented by simultaneously photographing the objective fields of both cameras, displacing one camera a predetermined distance relative to the other camera and repeating the step of simultaneously photographing, and repeating the displacement and simultaneous photographing steps over the entire viewing field; the method steps are repeated at a later time and a comparison is made of the viewing field images reproduced at the two times to identify relative changes in parts position with high resolution.

Abstract: A system for electrically heating a hose of the type used to transport one or more fluid components from a remote location to a point of application includes at least one fluid conduit and an electric heating element enclosed within a thermal insulation blanket to form a hose construction having predetermined heat transfer characteristics. A remotely positioned module enclosed in a thermal insulation blanket and containing an electric heater and temperature sensor provides a hose simulator having heat transfer characteristics substantially identical to that of the hose. An electrical power drive circuit connected in parallel to the hose heating element and the module heater is controlled by a temperature control circuit responsive to the temperature sensed within the module by the temperature sensor. The temperature control circuit is further responsive to an ambient temperature sensor physically separated from the hose and module.

Abstract: Disclosed is a method of and apparatus for heating and cooling. The method and apparatus employ a thermodynamic moat across which heat energy conductance can be entirely prohibited. The moat comprises a heat source for a heat pump. The heat pump can be contained within the thermal protection of the moat. Thus its energy of operation may be added to, rather than lost from, the system. Structures for absorbing solar irradiation are disclosed, as are means to contain these structures within the protection of the moat, thereby to overcome grave deficiencies of solar collectors used in cold climates. A method of and apparatus for utilizing the solar absorber structures for summer cooling are also disclosed.

Abstract: An optical fiber communications system includes an optical pathway defined as a closed optical loop with a signal source introducing a fixed frequency optical signal onto the loop as a reference signal for system wide propagation. Each terminal device in the system includes a thermally controllable bus tap resonator which can be controlled in a step-wise manner to support plural sets of resonant modes having corresponding different free spectral ranges with one mode of each supported set of resonant modes frequency locked to the system reference signal and another mode used for communications purposes. The bus tap resonators are thermally controlled to allow each terminal device to tune from a first set of resonant modes having a first free spectral range to another set of resonant modes having another free spectral range so that the frequency of the mode used for communications in the latter set will be different from that in the former set.
