Abstract: During electrophoretic enamelling, an enamel slip forms on the device for suspending the workpiece. When the workpiece is removed from the suspending device, said enamel slip may result in an accumulation of slip around the receiving hole and render the workpiece unusable. The invention proposes that the suspending device (2) for the part (1) is a metal pin (7) coated with plastic or pressed material, or is composed entirely or partly of plastic or pressed material and contact is made with the part (1) from its rear side. This inventive step is capable of preventing an accumulation of the slip around the receiving hole (3) of the workpiece (1). <IMAGE>

Abstract: A memory cell reading circuit has a reference cell bit line and a matrix cell bit line connected to a supply voltage through respective loads and furthermore connected by normally-off equalization transistors which are enabled by a first clock signal. The bit lines are further connected by normally-off resistive equalization transistors whose resistance is significant in conducting conditions. The equalization transistors are enabled by a first clock signal and the resistive equalization transistor are enabled by a second clock signal which has a duration that extends longer than the first clock signal. The memory cell reading circuit decreases the "read" time required for a memory cell, as compared to reading circuits previously used.

Abstract: A metal carrier for a sealing or trimming strip or the like, for attachment to a flange surrounding a particular door or similar opening on a motor vehicle body, is manufactured from a longitudinal metal blank by performing thereon a number of different metal cutting operations. As shown in Figure 6, apertures 38 and 72 define the ends of a particular length of carrier though do not completely severe the metal blank. At a region 42, the blank is unslotted. Over regions 44,52 and 66, different formations of slots are cut. A diamond-shaped aperture is formed at 62. The various cutting processes produce a channel-shaped metal carrier (Figure 8) having different slot formations along its length and thus having different characteristics to suit the different requirements at particular positions around the door opening. The diamond-shaped aperture 62 produces a V-shaped notch where the carrier may be bent at right angles to form a sharp corner. Apertures 38 and 72 facilitate precise cutting off of the length of carrier. The cutting operations may be performed continuously and automatically, according to a predetermined program, along the length of the blank.

Abstract: A mechanical sensor is placed beside the return run of the steps on an escalator or moving walk. The sensor is biased toward the steps so as to bear against each step passing thereby. If a step in the series is missing from its normal position, the sensor will move in the direction of the step run and will open a switch in the escalator power circuit thereby shutting off power to the escalator. The switch can only be manually reset by a mechanic from a location which is closed off to the public.

Abstract: The invention is a termination circuit which may be used to terminate a tester end of a transmission line between the tester and a digital device under test (DUT). The termination circuit is a clamp circuit which acts as a non-linear resistor of infinite resistance for termination voltages between zero volts (or low logic level voltage) and the power supply voltage V CC  (or high logic level voltage) of the DUT, and which provides a substantially constant slope resistance set to equal the characteristic impedance (Z₀) of the transmission line for voltages outside this range. 
     Given that the output impedance of the DUT is less than the characteristic impedance Z₀ of a transmission line, and given the characteristics of the clamp circuit, all reflections on the transmission line as a result of unmatched impedances are totally eliminated by the clamp in twice the delay time of the transmission line. After the reflections are eliminated, the clamp acts as an open circuit. 
     This clamp circuit may be used in virtually any application where reflections are a concern.

Abstract: A switching state detecting apparatus capable of preventing output voltage hunting caused by mechanical switch contacts bouncing when changing state and creating voltage fluctuation (chatter) comprises a passive filter (510) connected to the switches (S1 - Sn) and a comparator (507) for comparing the output value of the RC filter with a threshold level to then output a voltage value. The comparator changes the threshold level when the output voltage of the comparator is inverted, thereby preventing the apparatus from hunting. The output of the comparator is potentially divided and the divided output potential is superposed onto an initial threshold level to provide a second threshold level exceeding the voltage chatter level of said switches.
