Abstract: A device for counting and classifying load cycles in supporting structures with various loads, bridges, cranes, or tracks for example. A measuring instrument (2) is attached to an attachment side (7) of a load-cycle counter (1) and accommodates a mechanical strain amplifier (3). The ends (8 & 8') of the strain amplifier are much thicker and more resistant to strain. Its middle (9), which includes a strain gauge 10, is much thinner and more sensitive to strain. The ends are fastened to the attachment side. Any signal deriving from traction, force, or flection, and emitted by the strain amplifier (3) is forwarded through a digitalizer (4). The data are processed and stored in a signal processor (5).

Abstract: Device for cutting sheets of material, with a counter (12) for the material to rest on, a blade to cut the material, and a holdfast (11) that can be lowered onto the material by a mechanism (10) and raised off it by a spring (6). When the spring in such a device breaks, the holdfast can drop and injure the operator. The object is to prevent such injuries. An interceptor (7, 8, & 9) accordingly brakes the holdfast when the spring that raises it is broken.

Abstract: A joint between a hot and unrefrigerated pipe (1) and a refrigerated pipe (2). The end of the unrefrigerated pipe is bifurcated in cross-section, leaving two sections joined at one end. The exterior section (6) is fastened tight to the refrigerated pipe (2). The interior section (5) extends into the refrigerated pipe leaving a radial and axial gap. The cylindrical space between the interior and the exterior section is full of heat insulation. There is a flexible component, an O ring (13) for instance, between, and resting tight against, the face of the refrigerated pipe and that of the interior section of the unrefrigerated pipe. The insulation comprises an axial series of layers (10, 11, & 12), each with a different heat conductivity.

A light spot is imaged along the length of the channel. The channels are electrically isolated from each other. The channels may be proportional to a selected keystone pattern, and the channels may be rectangular-shaped and accommodate keystoning effects of an imaged beam.

Abstract: A screw press in which a screw continuously dewaters a suspension. The screw has a threaded section and a downstream compression section with a variable squeeze, and the screw is powered to forward the suspension. A housing accommodates the threaded section and the compression section with the variable squeeze. The suspension is admitted in dilute form at an intake at one end of the press. At another end of the press, the suspension is delivered in dewatered form downstream of the compression section through an outlet. The housing is in the form of a wire basket permeable to liquids and impermeable to solids, and is axially displaceable back and forth adjacent the unthreaded compression section between a non-operating position and an operating position to vary an effective length of the basket. This effective length is zero in the non-operating position for emptying the press.

Abstract: A device for laying on and stacking off cut stacks of sheets of material for the purpose of constructing overall stacks. The device includes a counter that travels vertically up and down and horizontally in and out, a mechanism that lays the cut stack onto the counter, and a mechanism that secures the cut stack as the counter travels out in order to stack off the cut stacks. The front of the counter tapers in. The counter has a forward section and a rear section for accommodating the cut stack. The forward section pivots on the rear section and can be pivoted between two limiting positions by applying a force such that in one position the surfaces of the two sections constitute a horizontal plane and in the other position the surface of the forward section slopes down from that of the rear section. Such a device is compact and ensures ideal laying on and stacking off of the cut stack.

Abstract: A method of burning coal with less than 10% volatiles in a burner supported by air. The coal is pulverized in a pulverizer and supplied to the burner mixed with a vehicle in the form of air. The object is more reliable ignition. The coal is separated from the air before it enters the burner and is combined into a new mixture with heated air. The second mixture is forwarded at a higher temperature and with a lower level of coal. The coal is separated from the second mixture and combined into a third mixture with heated air. The third mixture is forwarded at a higher temperature and with a higher level of coal.

The ring is re-adjusted from time to time by the casino personnel to contaminate the probabilities.

Abstract: Pivot for articulating the load-bearing components of a jack. The pivot comprises a shaft that rotates in a bore. The components are lengths of U section or have lateral flanges or upright edges that overlap in the vicinity of the pivot. The object is to decrease the weight of the jack. Instead of a solid bolt, the axis is a hollow neck (19) stamped through the sides (15 & 17) or flanges (13) of one component and extending through the bore (18) in its counterpart.

Abstract: A cab for accommodating the operator of a vehicle or machine, especially a traveling crane or other type of construction machinery. It comprises a seat for the operator, an operating-information display system with a monitor and display instruments in the seated operator's field of vision, and at least one optionally multiple-function operations-control device directly within his reach. The information-display system consists of a monitor with a liquid-crystal display and of a projection screen remote therefrom. The screen pivots around one axis and tilts around another axis at an angle thereto within the operator's field of vision. A source of light behind the monitor projects the displayed information onto the screen.

Abstract: An arrangement for monitoring vehicular traffic and providing information and warnings to drivers of traffic disruptions, driver error, dangerous road conditions, and severe weather. Road and traffic conditions are detected with roadside traffic sensing equipment, and the conditions are displayed over luminescent elements with signal lamps distributed at intervals along the road and combined into chains of lamps. The luminescent elements are illuminated simultaneously or in sequence for providing continuous traffic information. A processor network and a signal network are combined through a communication network to regulate the luminescent elements by processing, if necessary, under real time controlled conditions.

Abstract: In a fire alarm device for detecting the physical quantities of substances arising from the outbreak of a fire and giving a fire alarm, membership functions showing the correlation between an arising quantities calculated by the detected physical quantities and the danger degree which a man would feel with respect to the physical quantities are preset, the danger degree with respect to the arising value calculated by the physical quantities actually detected by a detection means is obtained by using the membership functions, and an alarm and control in accordance with the danger degree is given. Therefore, there is provided a fire alarm device capable of judging the outbreak of a fire based on an actual fire situation and giving an alarm and control in accordance with the degree of danger which a man would feel with respect to the scale, situation and so on of the fire.
