Inventor: SICK E
IPC: G01N21/89
Filed: 1979-02-26
Abstract: Detection apparatus for finding holes in moving webs uses a row of individual mutually sideways displaced stepped mirror strips in combination with a scanning device which periodically scans a light beam from a laser over the individual mirrors of each strip, to generate a scanning light curtain directed at the surface of a web. A detection device comprising a row of individual Fresnel lenses and associated photoelectronic detectors is arranged parallel to the row of mirror strips to receive light transmitted through any hole present in the web. The individual Fresnel lenses focus any light received onto their associated photoelectric detectors the outputs from which signify the presence of the hole. Means are provided for introducing a degree of divergence into the beams deflected from the stepped mirrors and forming the light curtain whereby the light curtain scans a cross the web without gaps.

Abstract: Substantially ash-free carbonaceous reductant for use in reduction processes is made by recovering carbon from unused carbon monoxide. The carbon monoxide contacts a catalyst which promotes formation of carbon on the catalyst. Since the off-gases from many metal ore reduction processes employing coke include a significant quantity of carbon monoxide, this carbon monoxide may be recovered and used to form the reductant which is fed to the reduction process to replace a part of the coke consumed. Provided most of the carbon monoxide in the off-gases is utilized, very favorable cost savings are achieved when the ash-free reductant is used in place of the coke. Moreover, in some instances, the ore being reduced may be used as the catalyst. Since this ore-catalyst is at least partially reduced during manufacture of the reductant, a benefit is obtained.

Abstract: A temperature-controlled bimetal switch is formed of a flat housing with an upper wall and a lower wall closely spaced apart. A fixed contact is secured to the inner surface of the upper wall and a curved bimetal snap plate and a contact spring are positioned between the upper and lower walls. The housing is formed of a transparent or translucent rigid plastics material permeable to radiant heat. A movable contact is formed on one end of the contact spring and is displaceable into and out of contact with the fixed contact by the snap plate. The snap plate is loosely secured to the contact spring and is positioned so that radiant heat passing through the housing directly impinges on the snap plate.

Abstract: A data transmission system is described where data signals are bidirectionally transmitted between a data transmitter and a plurality of data receivers in a self-clocking bit streams carried on true data and complement data signal lines and a non-return-to-zero (NRZ) bit streams on a return data signal line. According to an inventive data transmission scheme, data signals are transmitted by the data transmitter by utilizing the four possible two-bit binary states of the true data and complement data signal lines. Of the four two-bit binary states, a word state is provided before and after the data signal and a one state or zero state followed by a bit state is provided for each bit of the data signal. The data receivers detect the bit state to recover a bit clock signal and detect the one state and zero state to recover an NRZ data signal. In response to the bit clock signal, the NRZ data signal is serially shifted into a register while a previously parallel loaded return data signal is shifted out of the register and applied to the return data signal line. The inventive data transmission scheme is self-clocking and highly immune to speed and timing variations in the transmission. The inventive data transmission may be advantageously utilized for data transmission in many different data transmission systems, such as computer systems for data transmission between a microprocessor and peripheral units and control systems for data transmission between a central control station and geographically remote stations.

Abstract: A device for motorized manoeuvring of a counter-balanced folding door (1, 2) consisting of a motor driven driver (11) which is designed to move itself up and down alongside one side edge of the door. The driver is connected via a coupling device (17) to the bottom part of the door leaf (2). Upon opening, this has an initial horizontal oscillatory axel (21), which is parallel to the hinge joint axel (7), that connects the upper and lower parts of the door leaf (1,2) and which is positioned lower than the hinge joint axle. The driver (11) in combination with the coupling device (17) brings about an initial horizontal force effect on the lower part of the door leaf (2) when the door is opened, so that it initially oscillates around the oscillatory axel (21) with accompanying rotation in the hinge joint (7). The coupling between the driver (11) and the lower part of the door leaf (2) is made so that a combined change in the direction of power and power exchange is obtained outgoing from the driver's (11) vertical forces of influence.<IMAGE>
