Abstract: A culture cup for sampling and microbial-count determination, comprising a body and a tightly closing removable lid, the bottom of the body being provided with depressions for accomodation of at least one culture medium. The lid on its underside may be provided with a recess for accommodation of a condensate absorbent, and the body of the cup with a shoulder to serve as a seat for the bottom of the lid. The lid and body are threaded for engagement. By placing a culture medium in the depression, a biological specimen such as urine or blood can be added in just sufficient quantity to wet the culture so pouring and handling are reduced. Culture and analysis can then be undertaken in the usual manner using the cup body as the carrier of the culture medium.

Abstract: The apparatus has multiple independent stations each having a master sleeve with an image in semipermanent fixed primary dielectric toner formed thereon. The image is transferred directly or by way of an intermediate transfer roll. The master sleeve is charged in light, the toned parts retaining charge. The resulting now charged image is toned with a pigmented secondary toner and this double toned image is pressed against the passing substrate or brough very close to it either directly or through the transfer medium. An electrical field is established between the substrate and the sleeve or transfer medium, the toner transferred to the substrate and the sleeve or transfer medium circulate back to pass through the same process of charge, tone and transfer. The transferred images are fixed between or during movement through the stations. Image density information can be used to control change in the electrical field conditions or other parameters. The impressions from each station are applied in registration.

Abstract: In a video processing system including comb filters for separating interleaved luminance and chrominance components, the time of occurrence of the color synchronizing component of the composite color video signal is detected after the comb filtering and separating of the luminance and chrominance components. The composite signal components include spurious frequency variations which accompany the composite signal during playback from a video disc. A first phase locked loop coupled to a frequency translator is used to remove the spurious frequency variations from the separated and frequency translated chrominance components. A second phase locked loop is connected between a second frequency translator and a clock controlled delay line. The second phase locked loop tracks the spurious frequency variations in a manner to assure that accurate combing of the component signals occurs at the output of the comb filters. The same reference frequency is used in the first phase locked loop as well as in the second frequency translator.

Abstract: In a system for the registration of the passage of articles through a previously determined field the transmitter (2) and the receiver (3, 4) are connected to a common aerial (1). A marker (18) on the articles receives and transmits electro-magnetic signals by the passage of a transmitter-and receiver bracket. In order to achieve the greatest possible security from incorrect registration the transmittance-and receiving function changes at a suitably high frequency, and an analytical circuit (7) monitors the number of received signals from the marker (18), and compares the frequency of these to that of the signals which are transmitted by the transmitter (2). The marker (18) consists of an inductive and a capacitive component, and the aerial (1) is shaped like a figure eight.

Abstract: A self-centering steady rest according to the invention intended to improve the present technical ability of a steady rest to center a round workpiece with greater accuracy. This is achieved by virtue of the fact that the steady rest has three gripper pivot arms with support rollers, said pivot arms having the same bending stiffness regardless of its gripping force and that one of the pivot arms has an extended opening movement so that the workpieces of approximately the maximum gripping diameter can be easily inserted and removed from the steady rest with the bridge loader. Moreover, the gripping force of the pivot arms can be adapted to the value required to make the workpiece center and thus the life of the support rollers can be appreciably increased.

Abstract: A method of controlling a welding operation during arc welding between a fusible electrode and a workpiece, wherein the welding operation alternates between arc periods and short-circuiting periods, includes the steps of sensing a first parameter of the welding operation, for example the arc voltage between the electrode and the workpiece, generating a first signal representative of the first parameter, sensing a second parameter of the welding operation, generating a second signal representative of the second parameter, filtering the second signal to provide a filtered signal, generating a desired value signal based upon the filtered signal and controlling the welding operation based upon the difference between the desired value signal and the first signal. According to the method of the present invention, any changes in the second signal that occur at a frequency outside a predetermined frequency range, which includes a desired short-circuiting frequency of the welding operation, are attenuated such that the desired value signal is less affected by these changes than by changes occurring at a frequency within the predetermined frequency range. An apparatus for carrying out the method includes a band-pass filter having a pass band including the desired short-circuiting frequency.
