Abstract: The invention relates to a tailstock for lathes whose clamping force can be exactly adjusted over a wide range in many intermediate steps in order to thereby design the tailstock advantageously especially for automatic use. In this arrangement, a row of pistons arranged in parallel and having different cross-sectional areas act on the sleeve unit, which pistons are loaded individually or in combination by a common working pressure. However, the sleeve unit can only be moved over a slight axial distance inside the basic body and, when inoperative, is always spring-loaded in the position advanced to the maximum extent. To clamp a workpiece, the tailstock is moved forward against the workpiece until the entire sleeve unit is pushed back slightly into the basic body of the tailstock, as a result of which, via limit switches, the tailstock is braked and secured in position and the hydraulic cylinders which put the sleeve unit under a preselected clamping force are loaded. <IMAGE>

Abstract: A glitchless terminal count indication digital counter (100) having a clock signal (LK) as an input thereto is disclosed and comprises a state logic means (120) comprised of a plurality of DQ flip-flops (303,305,307,309) for providing a digital count with the clock signal being sent to an input thereof, a next state decode means (115), a next terminal count decode means (125) for providing an indication at its output that the digital output count will reach a terminal count at the next clock cycle, and a terminal count logic means (130) for obtaining the indication from the next terminal count decode means (125) and providing therefrom at the next clock cycle a glitchless terminal count indication. The next state decode means (115) has inputs (D0...D3) and outputs, with the digital count being an input thereto,and the state logic means (120) and the next terminal count decode means (125) being coupled to the output thereof. the terminal count logic means (130) is preferably comprised of at least one D-type flip-flop having both a clock signal (LK) and the next terminal count decode means (125) as inputs thereto, and logic circuitry for forcing the output terminal to indicate the reaching of a terminal count. When the next terminal count decode means (125) senses the penultimate count, it changes the value of its signal which is supplied to the flip-flop of the terminal count logic means (130). Thus, upon the next rising clock signal, the terminal count flip-flop will change its output and, via the logic circuitry, will force the output terminal of the counter to assume a terminal count value.

Abstract: An apparatus and method for fluid distilla­tion in general, and in particular, of water, adapted for consumer or home use, but capable of being made and operated so that it is suitable for separating solvents and solutes and other industrial use. The apparatus includes a housing (12) having divider structure to form one or more compartments (26) for receiving water to be dis­tilled. The divider structure also presents a fluid passage for receiving water vapor which is formed when the upper portion of the water in the housing is boiled by a heater. An aerator (34) is provided in the housing below the heater (50) and in a location within the water compartment. The aerator (34) operates to direct air under a slight pressure into the water so that air bubbles can be generated in the water. The air bubbles will rise and break the surface of the water as the upper part of the water is being boiled by the heater. This causes a vapor pressure to be generated in the space above the water level and water vapor is then caused to move through the fluid passage (24) downwardly to a lower chamber in which the water vapor is collected as a condensate. As the water vapor moves downwardly in the fluid passage (24), it moves in heat exchange relationship to the water in the compartment of the housing.

Abstract: The invention concerns Asynchronous Time Division Switches particularly for packet switching. In one embodiment a switch has 256 ports running at 155 M bits and is capable of switching incoming data cells at each of the input ports to any one of 256 output ports. At each input port a switch sequentially distributes the received data cells over 16 outputs each of which is connected to a different DMR circuit. There are 256 DMR circuits each having 16 inputs and 16 outputs. A DMR circuit is a fixed space switching device which has N inputs, N time intervals and N outputs and operates cyclically so that each input goes to each output for 1/Nth of the time. The inner stage of the ATD switch comprises 256 central switches each having 16 inputs and 16 outputs. Each central stage switch has its 16 inputs connected to 16 different DMR circuits. The fourth stage of the switch consists of another array of 256 output DMR circuits with each central switch being connected to 16 different output DMR circuits. Each output DMR has its outputs connected to 16 different output ports. The internal circuitry of the ATD switch runs on 20 M bits. When a data cell is received at an input port its destination is derived from a header attached to the cell. Control circuitry enables the receiving port to request three address to query three possible routes through the switch. The ability to provide this series of questions is given by staggering the windows through which an output port can communicate with the central switches. Although data streams are received asynchronously the operation of the ATD switch is synchronous. 
     The switch is potentially capable of switching non ATD, synchronous traffic. Mixed mode of operation is possible.

Abstract: A recording material contains on a 20 - 200  mu m thick paper or plastics support a 2 - 30  mu m layer of a dispersion of particles of a light-sensitive organic substance which forms a decomposition product when light-exposed and an organic substance which reacts imagewise (e.g. a diazo compound and its coupler or a photo-oxidizing agent and a leuco dye); at least one of these may be microencapsulated. The material is imagewise exposed, e.g. from a fluorescent lamp, and overall heated in two steps, firstly at a temperature (e.g. 60 - 90 DEG C) at which no formation or fixing of the image occurs and then at a higher temperature (e.g. 80 - 150 DEG C) to cause the reaction to form a visible image. The first heating can be at the time of the imagewise exposure, e.g. by the heat from the lamp. The material is transferrd between the heating steps as fast as possible. The use of the first heating allows less energy to be used for the development step. Diazo material used can contain other components such as a color forming aid or substance fusible at 50 - 150 DEG C. Visible images are formed of good colour density, low background fog and good shelf life before use.

Abstract: A laser (32) generates a probe beam (34) which is passed through a polarization section (36) to give the beam a known polarization state. The probe beam (34) is then tightly focused with a high numerical aperture lens (46) onto the surface of the sample (40, 42). The polarization state of the reflected probe beam is analyzed (48). The angle of incidence of one or more rays in the incident probe beam is determined by a detector (50) based on the radial position of the rays within the reflected probe beam. This approach provides enhanced spatial resolution and allows measurement over a wide spread of angles of incidence without adjusting the position of the optical components. Multiple angle of incidence measurements are greatly simplified. Data from the detector (50) and a rotatable polarization filter (330) are supplied to a processor (52) that carries out the ellipsometric calculations.
