Abstract: ABSTRACT OF THE DISCLOSURE.           To provide for fine-adjustment of the relative angular position of a driven body of rotation, such as a plate cylinder (1) of a printing machine, and having a driven shaft (21, 4]) with respect to a driving shaft (9, 40), an axially shiftable intermediate shaft portion (149 53) is positioned between the driving shaft (9, 40) and the driven shaft (21, 41) and the body of rotation, respectively.  An elastic coupling structure (16, 24; 55, 57), for example a composite stacked leaf spring, and having the characteristic of being circumferentially stiff but axially flexible,  couples the intermediate shaft, for axially shifting movement, between the respective shafts.  Preferably, two such elastic coupling structures are provided.  The intermediate shaft is axially shifted in response to changes in transmitted torque by a drive train from a drive motor (4) to the printing cylinder (1) under control of a torque responsive element, such as a strain gauge (37) coupled to a servo system which axially shifts the intermediate shaft portion, or by a torsion sleeve (46) which can twist in response to transmitted torque, the change in axial dimension upon twist of the torsion sleeve being trans-mitted through a hollow shaft to the intermediate shaft portion. Thus, circumferential register of the driven body of rotation, for example the printing machine cylinder (1) can be controlled in dependence on transmitted torque and register errors due to loading on the printing cylinder can be eliminated.  The system is also applicable to other apparatus structures, such as rotary punches and the like.

Abstract: ABSTRACT A power and communication system for a building, and particularly a residential dwelling wherein there are provided a plurality of receptacles throughout the building, each connected by a cable to a source, which may provide different voltages and either AC or DC. and having a control interface for selectively switching the desired power to each cable individually.   The control interface may also connect each cable to a selected signal transmission line, such as telephone, radio, TV., etc.   The cable includes a pair of power conductors and an optical fiber which transmits to and receives from the control interface light signals informing the control interface what power or communication connection is required for a particular receptacle and possibly at the same time providing signal messages to each receptacle.  The single optical cable can transmit an interrogating signal to the receptacle, which signal is transferred through a special plug and socket connection having a mating optical coupler to an appliance equipped with a microprocessor programmed for replying by way of light signals sent back to the interface through the same coupler and optical fiber.  The control interface is thus informed as to what power and communication connections the appliance requires and how the appliance should be subsequently monitored.  In order to allow the use of appliances which are not equipped with a microprocessor, the plug of such an appliance can be equipped with a retro-reflective element located to align with the coupler of the socket so that a reflected signal informs the control interface that the appliance must be supplied with power of conventional frequency and voltage.  In the disclosed system, the receptacles are not supplied with power until a suitable equipped appliance is plugged in or turned on, thus improving the safety of the power supply, and since only slightly modified  socket and plug combinations are used, the system and appliances are compatible with conventions outlets and appliances. Communication signals for telephone, TV. and monitoring systems can be transmitted through the same receptacles provided for power outlets.

Abstract: The invention relates to a method for producing lead having a sulphur content beneath about 2%, from sulphur-containing oxidic lead raw materials contaminated with zinc and/or other readily oxidized elements, by smelting the materials in afurnace in which furnace contents can be agitated. When practicing the method, the lead raw materials are charged to the furnace together with iron-containing fluxes and solid reduction agents. The charged materials are heated under agitation, to form a lead phase and a slag phase. The amount of reduction agent charged is selected so that at least all the lead contained in the furnace is reduced to lead metal and the amount and composition of the fluxes are selected so that a terminal slag is obtained in which the sum of the iron and zinc present is 30-40%, and so that the slag has a content of 15-25% of both Si0<sub>2</sub> and CaO + MgO.Lead raw materials, fluxes and reduction agents are suitably introduced in a plurality of charges, with intermediate moderate heating, prior to commencing the smelting process.

Abstract: A method for detecting flaws and surface defects in metal workpieces, particularly in non-magnetic steel workpieces. The surface of the workpiece (2) is heated by passing the workpiece is in its longitudinal direction through an induction coil (3), scanning the surface of the workpiece with an infrared camera (4) transversely across the surface of the moving workpiece immediately after induction heating and recording a streaked pattern temperature profile in which the streaked pattern repeats itself where there are flaws in the surface. An induction coil (3) is used which has a current frequency which gives a penetration depth of the induced current in the workpiece which is greater than the depth of the flaws which are to be detected. The flaws and surface defects are detected by recording a lower surface temperature than the rest of the surface of the workpiece by scanning the temperature profile immediately after induction heating.
