Abstract: 1503020 Load - responsive brake valves KNORR-BREMSE GmbH 7 March 1975 [9 March 1974] 9714/75 Heading F2F A load-dependent brake valve arrangement for a railway or motor vehicle pneumatic brake comprises a first piston 9 movable to supply pressure medium to the brake cylinder, a second piston 10 coaxial with the first and movable in response to the supply of control pressure thereto and a variable lever-arm transmission associated with the pistons so that displacement of the second piston is accompanied by displacement of the first piston. The transmission includes three levers 11 extending outwardly of the common axis of the pistons and each acting at one end on an abutment A in the housing 12 and at the other end on the first piston 9 at C there being an adjustable pivot B intermediate the ends of each lever and engageable by the second piston. The pivots B are equally spaced from the common axis and adjustable conjointly relative to the axis by a control element rotatable about the axis, as a function of variation in vehicle load, to vary the ratio of displacement of the first portion relative to the second piston. Adjustment may be performed by means of a disc 14 having control slits 28 and located between guide discs 13 formed with radial slots 26, pins 15 forming the pivots being displaced radially as disc 14 is rotated. Alternatively the pins 15 may be replaced by balls guided in tracks of semicircular cross-section. The disc 14 may form the face of piston 10 and the radial tracks 26 may be arranged in levers 11 instead of in the disc. The application of pressure Cv at inlet 5 raises the two pistons 9, 10 against a spring to admit actuating air R past a valve to an outlet 7. The pistons therefore balance operating pressure C against the pressure Cv in the ratio given by the leverage ratio of the levers 11. In the embodiment shown in Fig. 10 a loadresponsive actuator has a two stage operation, a low load stage where two pistons 18, 29 operate in tandem under load-responsive pressure T, and one set of brake cylinders is operated via line C 1 , and a high load stage in which the pressure T only acts on the piston 18, but two sets of brake cylinders are operated, via lines C 1  and C 2 . The changeover occurs when a bore 32 in the boss of piston 29 rises past a seal 32<SP>1</SP>, so allowing air at pressure T from the chamber 38 into the chamber 35. This depresses control piston 37 and allows pressurized air into the chamber 30 so that the piston 29 sinks to its lowermost position. In this position the central stem of the piston contacts the seal 39 so that lines 7 and 8 are connected, and so that the space above the seal is no longer vented through port 42.

Abstract: This invention has for its object to eliminate the problem of loud noise and violent vibrations in machines having transient force characteristics of the type appearing in punching or cutting presses. According to the invention this is achieved by means of a damping device comprising a housing defining a chamber filled with a hydraulic fluid said fluid being pre-compressed by a first piston acted on by the force and said pre-compressing being carried out to a pressure corresponding the force to be dampened. Immediately before the force relief the force is arranged to act on a second piston of bigger cross sectional area said second piston preventing a too rapid force relief of the press frame due to the pre-compressed hydraulic fluid. The force relief occurs rather slowly due to the fact that the hydraulic fluid trapped in the chamber is exhausted via control valve keeping the pressure in the chamber almost constant and only permitting a certain volume flow therefrom.

Abstract: An apparatus for heating or cooking food is described which comprises a plate forming the hot horizontal surface on which the food to be cooked is placed, a heating source underlying the plate and a cover above said plate which defines a mainly closed space.  The plate has high thermal conductivity. Preferably, the plate has a raised edge effective to circumscribe and define a space for locating and containing the food.  The plate may be inverted and the apparatus may be used as an open grill.  In this arrangement heat is transmitted by conduction. The plate is provided with essentially vertically extending passages located, in the perimetral  parts of the plate, in section in vertical planes, in such a way that the lower mouth or inlet of said passages fully communicates with the space underlying the plate so that active circulation of superheated air is established between the space underlying the plate and the space above the plate and defined in the inside of said cover. When the plate is inverted, circulation is prevented or at least strongly hindered.  Heat given off by the heat source is transmitted, substantially completely, through the planar portion of the plate.

Abstract: A signal processor for use with an imaging sensor system that provides enhanced video imagery. The signal processor may be coupled to a FLIR system, for example, which comprises a plurality of detectors that are scanned across an image scene and reference temperature source during separate portions of each scan cycle. The signal processor comprises an input processor coupled to the imaging sensor system which processes analog signals derived from each of the plurality of detectors. The input processor normalizes the analog signals relative to one another during the active portion of the scan cycle based upon stored data derived from a predetermined sensor responsivity calibration procedure. This normalization function equalizes the gains associated with all channels of the sensor system. The input processor also restores the DC levels of each of the sensor channels to respective DC values related to the reference temperature source during the inactive portion of the scan cycle. This function is performed during the calibration procedure and while the system is in operation. The input processor digitizes the signals which are applied to a scan converter. The scan converter stores the digitized signals and converts the stored signals into signals which are compatible with a video monitor employed to view the image. An output processor is coupled to the scan converter that is employed to process signals in a manner which permits software-controlled digitized image enhancement thereof, and which converts the enhanced signals into analog video output signals compatible with the video monitor.
