Abstract: The manufacture of a solar collector is carried out in such a manner that a reflecting plastic diaphragm (1), which is gripped at its edge, is uniformly stressed over its surface. This results in an approximately parabolic deformation of the diaphragm (1). The surface stressing is carried out by producing an excess pressure in a chamber (6) which is formed by tensioning a transparent second diaphragm (5) over the first diaphragm (1) and connecting it tightly at the edge. The heat-evaluating means are arranged at the focus (7). To increase the efficiency, the arrangement is made in such a manner that the curvature of the reflecting diaphragm (1) is greater than that of the transparent diaphragm (5). The latter can also have a support network (61). <IMAGE>

Abstract: Acylated chitin derivatives prepared by acylating a soluble derivative of chitin using an organic acid anhydride hitherto have not been able to effectively adsorb or separate substances with a molecular weight greater than 70,000. This problem has now been overcome by effecting acylation in the presence of a diluent, a porosity-regulating agent and one or more surfactant so as to obtain a porous acylated chitin derivative. In one embodiment an aqueous solution of the soluble derivative of chitin containing the diluent, the porosity-regulating agent and a surfactant is contacted with a liquid containing the organic acid anhydride and a surfactant. Typically, the porosity regulating agent is benzene or a volatile alkylbenzene, such as toluene or xylene, and the surfactant is a monolaurate, monopalmitate, monostearate, monooleate or trioleate of sorbitan or of polyoxyethylene sorbitan. The porous product can be employed as an ion-exchanger or in chromatographic columns as a filler.

Abstract: An embodded servo track following system and method for positioning a transducer (10) relative to a storage medium (13) to read and write data on the medium such as a magnetic disc. The system includes positioning means (15) energizable for moving the transducer to preselected recording positions relative to the storage medium. A plurality of side-by-side closely spaced alternately arranged odd and even servo tracks are embedded or recorded on the medium such that a pair of the odd and even servo tracks identifies a preselected position or informational data track on the medium therebetween. Each of the odd and even tracks generates a waveform having a net DC component. The DC component of the odd and even tracks are equal in magnitude but opposite in polarity such that the DC components of the odd and even tracks cancel each other when the transducer is disposed therebetween. Servo control circuit means is provided for sensing the output of the transducer and selectively energizing the positioning means to null the output of the transducer and thereby centre the transducer between a preselected odd and even track pair (e.g. on line 36).

Abstract: A conveyor 4 driven by a motor 5 feeds thermoplastic waste material 2, such as the trimmed-off edges of extruded plastics sheets, to a compression chamber 8 at the inlet of a heating box 10 of an extruder 11. The conveyor operates intermittently in synchronism with the movement of a plunger 40 operated by a hydraulic cylinder 42 which compresses the waste material to the level of a restraining member 50 controlled by a pneumatic cylinder 54. The member 50 comes into operation as the plunger 40 reaches the bottom of its stroke and holds the plastics material in a compressed condition while the plunger 40 rises again, further material 2 is fed to the chamber 8 and the cycle is repeated, the member 50 being withdrawn shortly before the plunger 40 reaches the bottom of its stroke. Plastics material is progressively melted as it passes down the box 10 and under the pressure exerted by the compressed material is extruded through a die plate 16 in the form of strands 18 which, after passing through a water bath 20, are chopped into granules 35 by a rotary cutter 34 and fall into a bin 36 ready for re-use.

Abstract: An indicating system is constructed of first and second voltage comparators (10, 13), first and second output circuits (12, 15) which are respectively supplied with output signals of the first and second voltage comparators, and first and second indicating elements (21, 22) which are connected to a common output terminal of the first and second output circuits. 
     A first input terminal of the first voltage comparator is supplied with a first reference voltage (V,), and a second input terminal thereof is supplied with a control signal (V CONT ). A first input terminal of the second voltage comparator is supplied with a second reference voltage (V 2 ), and a second input terminal thereof is supplied with the control signal (V CONT ). 
     When the voltage level of the control signal (V CONT ) is higher than the first reference voltage (V,), the first output circuit (12) causes a current of a first polarity to flow to the common output terminal. As a result, the first indicating element (21) is lit up, and the second indicating element (22) is put out. When the voltage level of the control signal (V CONT ) is lower than the second reference voltage (V 2 ), the second output circuit (15) causes a current of a second polarity to flow to the common output terminal. As a result, the first indicating element (21) is put out, and the second indicating element (22) is lit up. 
     When the voltage level of the control signal (V CONT ) is intermediate between the first and second reference voltages (V 1 , V,) the first and second indicating elements (21, 22) are put out.

Abstract: A process for employing tobacco fines or dust is disclosed. The tobacco fines are dispersed in an aqueous liquid and applied to tobacco or reconstituted tobacco. In the preparation of reconstituted tobacco, the fines are incorporated into concentrated tobacco extract before the extract is recombined with the reconstituted sheet or into an aqueous carrier. The slurry of fines in extract or other carrier is passed through a homogenizer and then is applied as a coating to the sheet prior to drying and shredding. In application to tobacco strip and other tobacco blend components, the fines are combined with casing and the combination is homogenized to reduce the particle size and produce a uniform distribution. This is then sprayed by the casing applicator system onto the strip; the dried product is no more dusty in subsequent cutting and handling than is the strip without the added fines.

Inventor: MCGOWAN MICHAEL J
IPC: G07C3/14
Filed: 1982-12-28
Abstract: A control method and apparatus for a metal-forming machine such as a cold heading machine are described. The described method and apparatus monitor machine operation during production and permit relatively large deviations from a prescribed norm over a short term without shutting down the machine, while ensuring longer term compliance to relatively small tolerances from the norm. The described controller first determines an average of a measured parameter such as the hit energy applied to a group of workpieces resulting in acceptable metal-forming during a training mode and then stores this average as a target value. The controller then establishes a set of tolerance windows to be used to control forming operations in a production mode. 
     In production, the controller repeatedly measures the machine parameter and then compares selected averages of the measured parameter with the target value and the respective tolerance window, and indicates out-of-tolerance condition whenever one of the selected average falls outside the respective window. The tolerance windows are selected such that short term averages or single values of the measured parameter must deviate from the target values by larger amounts than long term averages before the controller signals an out-of-tolerance condition. For example, the described controller operates to interrupt machine operation when a single measured value of hit energy deviates by more than 16% from the learned target value, when a group of 4 measured values of hit energy deviates by more than 8%, when a group of 16 measured values of hit energy deviates by more than 4%, or when a group of 64 measured values of hit energy deviates by more than 1%. 
     The disclosed controller also signals when the measured parameter is nearing an out-of-tolerance condition, and it acts to change the target-value-grádually during a warmup period of machine operation in order to reduce the number of unnecessary interruptions of machine operation.

Abstract: In most cases, the type and location of the occurrence of interference quantities by means of which operating systems, individual objects but also the environment are potentially endangered cannot be predicted, or not accurately so. The surveillance system is constructed with optical waveguides which are located at or in the objects/areas to be monitored, and the changes in optical characteristics, caused  directly  or  indirectly  in  the optical waveguides by such interference quantities are observed and analysed. For this purpose, the optical waveguides are run as an area-covering network. The analysing device is located at a central, possibly external, location. It is here, therefore, all information on interference quantities occurring is available. The individual measuring stations do not need to be entered. The optical waveguides used as detectors are at the same time used as transmission medium and frequently also as stores for this information which are not or only slowly volatile.
