Title: Microwave circuit for step-down frequency mixer - with pump frequency tuned input output pi filter, and fine tuning facility for intermediate frequency stage
IPC: H03F7/04
Filed: 1980-02-08
Abstract: The application is to microwave signal transmission, and the construction of a parametric congruent step down mixer with real mirror frequency terminal conductance. The input comprises a parallel LC circuit (Lh, Ch) which is tuned to the pumping frequency (p). It is linked to the output by a reactance diode (S) (o), RD) and an inductance (L). The output comprises a Pi filter with capacitors (Cx, C2) in the parallel limbs and an inductance (Lz) in the series connection. The intermediate frequency z, is determined by the fine tuning of the input circuit and the Pi filter. The components are chosen to match the load conductance (Gz) with the resonant output conductance of the mixer. The input-parallel circuit (Lh, Ch) may be constructed out of two parallel open feeders each approximately one quarter of the length of the pump frequency wave length.

Title: Extrusion wall thickness control system - adjusts measuring instrument after stationary condition in extrusion process
IPC: B29C48/92
Filed: 1988-07-15
Abstract: The wall thickness of an extruded plastic item is kept constant by calculating the mean thickness of the extrusion from the quantity of material delivered to the extruder per unit of time, the linear velocity, the specific gravity of the material, and the transverse dimensions of the extrusion. A measuring instrument is moved all the way across the extrusion surface, taking a series of readings, the thickness being adjusted accordingly. Periodically after a stationary condition in the extrusion process the measuring instrument is adjusted to match the mean calculated and measured values of thickness. The linear velocity or output of the extruder is then adjusted so that the minimum thickness measured is equal to the desired one.

Title: Recording system and image-processing system for object recognition or distance measurement
Inventor: ESCH JOHANNES HARM LUKAS HOGEN
IPC: G06K9/00
Filed: 1994-08-29
Abstract: The invention relates to a recording/image-processing system which can be used, with the aid of one camera and a mirror or mirror wall, to record three-dimensional images or objects, for the purpose of automatic object recognition or to carry out non-contacting measurements (contactless measurements) remotely (at a distance). The camera and the mirror are positioned in such a way that the object to be recorded or the person to be recorded is recorded both directly by the camera and also in the mirror via the same camera, after which the image is frozen in the memory of the computer linked to the camera and is processed. On the basis of the position of distinctive features, the exact position in space of those distinctive features is determined both directly and via the mirror. This can involve the use of a regular measuring grid with a known grid spacing behind the object to the recorded. This background is observed by the camera both directly and via the mirror. If the object has too few distinctive image points, additional distinctive points can be applied to the object with the aid of a light grid.

Abstract: The danger of explosion due to decomposition of high-pressure industrial process gases, such as ethylene, is reduced by maintaining in an inert atmosphere at least part of an evacuation system included between a pressurized vessel within which the decomposition may take place, on the one hand, and the atmosphere, on the other. The evacuation system to the atmosphere for the gases contained in the high-pressure vessel, includes (1) an evacuation pipe adjacent to the vesel; (2) a safety means separating the evacuation pipe from the vessel; (3) a sealing means located in the evacuation path of the gases and occupying the entire cross-section of the evacuation pipe; (4) a first gas supply circuit connected by a pipe to that part of the evacuation pipe that is located between the safety means and the sealing means, and means for the first supply pipe to control the volume of gas supplied by the first supply circuit; and (5) a second gas supply circuit connected by a pipe to the sealing system, and means for the second supply pipe to control the volume of gas fed by the second supply circuit. The apparatus is useful for the recovery of decomposition products for the purpose of averting atmospheric pollution, as well as for reducing the risk of explosion.

IPC: D04B37/00
Filed: 1981-07-31
Abstract: The present invention provides an apparatus for transferring knitted fabric from needles of a first knitting gauge to needles of a second knitting gauge. A row of parallel, elongate points are provided each being arranged parallel to one another and secured at each end to a movable frame. The bands pass through respective slots in two trick bars with the points being located between the two bars so that movement of the bands in unison carries the points from one trick bar to the other. If the slots in the respective trick bars are at the two selected knitting gauge then passage of the bands through the slots adjusts the spacing of the points from one gauge to the other.
