Patent EP-0246892-A2 (EP)
Inventor: KALAWSKY ROY STEVEN
IPC: G01D5/34
Filed: 1987-05-21
Abstract: An optical transducer is provided for measuring the position of an object. The transducer comprises a fixed polariser (22), a rotatable polariser (23), a drive unit (30) for rotating the rotatable polariser (23) in proportion to the linear or angular displacement in the position of the object (31); a light source, a light guide (24) for directing a beam of light of known intensity through the polarisers (22, 23) and a light guide (25) to pass the light to a detector for measuring its intensity, whereby the modulation in light intensity effected by the rotatable polariser (23) is indicative of the change in position of the object (31). If the light source is a laser producing a coherent beam, then the fixed polariser (22) can be omitted. In this way, the transducer converts linear or angular position into modulation of the intensity of a light beam by purely optical means.

Abstract: A system for forming components to have a predetermined contour includes a manipulator having four manipulating heads 44, 52, 56, 58 which engage longitudinally spaced portions of the component. The system uses the manipulator to determine the initial contour of an increment of the length of the component, compares the measured contour with the required contour to determine the contour or shape error and then controls the manipulator to apply one or more permenent set deflecitons in accordance with the required contour. The manipulator is then advanced relative to the component and further measuring and deflections steps are performed until the component has the required contour.

Abstract: A process is provided for the selective removal of basic materials from plant products, in particular, for removing nicotine from tobacco without materially affecting the content of the other components of the tobacco. Tobacco is. traversed with a solvent in the supercritical state or in the liquid state wherein nicotine and the other components dissolve in the solvent. The solvent is then passed through an acid-containing trap where the solvent is essentially freed of nicotine. The solvent, depleted of nicotine and enriched in the other components, is then recycled to the tobacco to reextract nicotine. In addition, the tobacco may be pretreated with a chemical base which does not substantially react withe the tobacco components under ambient conditions but rather is activated under the conditions of the extraction process. Pretreatment of the tobacco with a chemical base neutralizes nicotine salts and permits the extraction process to be carried out under milder conditions.

Abstract: A generally rectangularly shaped powder coating booth of a powder spraying apparatus is fomed of two main sections, each of which is constituted of wall and roof elements which are swingably interconnected to one another. The walls and roof of each half of the booth may be straightened out to form a flat, continuous and rectangularly shaped surface from which residues of powder may be removed easily and rapidly. Thus when the two halves of the booth are flattened out the booth is transformed into two parallel and spaced surfaces which can be cleaned by being vacuumed by a respective suction nozzle that is disposed to travel over and vacuum the surfaces automatically.

Abstract: A synchronizing clock signal generator has, in combination with a PLL circuit, a signal delay circuit (1) for delaying a reference input signal by a prescribed time and issuing a reference signal, and a shift register (2) receptive of the reference input signal and a clock signal which is an oscillation signal from a voltage controlled oscillator (5) or a signal produced by frequency-dividing (6) the oscillation signal by an integer, for issuing a comparison signal in synchronism with a clock signal. The comparison signal and the reference signal are compared in phase. Even if the reference input signal is not a pulse signal of a fixed frequency, a synchronizing clock signal can be reproduced, insofar as the reference input signal is a pulse signal with its polarity inverted at the time of a multiple of a prescribed natural period.

Abstract: 1. Cooking oven with an oven muffle. 2.1 In a known oven muffle, the vapour take-off opening opens in a vapour take-off duct which is integrated at the rear in a vertical connecting wall for an extractor hood situated above the cooking oven. Via the vapour take-off duct, the vapour flows out of the oven muffle, after passing through a filter device, into the region of the extractor hood. 2.2 In order that maintenance work can be carried out easily and quickly on the vapour take-off system by the user, the filter device (12) and a condensate collecting device (14) for the vapour condensing in the vapour take-off duct (4) are designed as a drawer-like unit. These units are in this connection accommodated in the connecting wall (5) and can be pulled out to the front. 2.3 The design makes easier the maintenance of the vapour take-off system in cooking ovens with a rear function wall.

The dispenser also includes means (75), contacting the edge of the first roll (30), having a first position for sensing the diameter of the first roll; means (84), connected to the sensing means (75), for biasing the sensing means (75) against the edge of the first roll (30); biased transfer means (51) for introducing the extended web (28W) of the second roll (28) into the feed roll nip (35); and stop means (75a), connected to the sensing means (75), the stop means (75a) being located to resist motion of the transfer means (51) at a ready position when the edge of the first roll (30) resists movement of the sensing means (75). When the edge of the first roll (30) no longer resists movement of the sensing means (75), the sensing means (75) and connected stop means (75a) moves to a second position which allows the biased transfer means (51) to move to a transfer position where the extended web (28W) of the second roll (28) is introduced into the feed roll nip (35).

Abstract: An integrated circuit chip with an on-chip test system has flip-flops arranged in ranks (50, 60,..., 90) and chains and interconnected by combinatorial logic (56, 80, ..., 100), each flip-flop having a test input fed directly from the preceding flip-flop (52, 58, 70, ...) bypassing the combinatorial logic and operative in the absence of a NOP (normal operation) signal. Multiplexers (40) couple the end of each chain to the beginning of the next. Each flip-flop acts as an ordinary flip-flop preceded by a multiplexer. An additional initialising input may be multiplexed into the flip-flops (Figure 2). The test input couplings may be non-linear, to prevent reconvergence of signals (Figures 2-5). To test the combinatorial logic feeding a particular flip-flop, a test bit pattern may be sequentially clocked into the flip-flops feeding that piece of combinatorial logic with NOP = 0, NOP set to 1 for one clock period, and the resulting bit sequentially clocked out with NOP = 0 again.

Abstract: A method and apparatus for detection of a digital synchronisation word, or sequence of words, uses a state machine. The state diagram is implemented in a detector memory with feedback of the memory output through a latch to constitute part of the next memory address. The input data is used bit by bit as another part of the detector memory address. A decoder memory decodes the state information in the detector memory output and produces synchronisation information. 
     A particular state diagram for sync acquisition includes feedback paths. A particular state diagram for lock maintenance enables lock to be maintained depending on the number of errors in the successive detected syne words.

Abstract: Half products expandable or puffable by microwave or convection heat energy are prepared by a) preparing a starch-containing material having a moisture content of not more than about 25%, b) extruding the moisture-tempered material at a temperature of about 80 to 110°C without causing expansion thereby producing a hot melt in a rope or piece form, and c) cooling the extrudate without substan­tially lowering the moisture content for a time necessary to harden up. The half-products contain not more than about 25% of moisture in a glass-like rope or piece form and are shelf stable without preservatives. Substantial savings can be achieved in manufacture, storage, shipping, and handling because of the low processing temperature and the storage stability of the dense and hard products.
