Title: Method of determining the residual oxygen content of the exhaust gases from internal combustion engines
Inventor: LINDENMAIER KLAUS DR
IPC: G01N25/28
Filed: 1982-09-25
Abstract: A method is described for determining the residual oxygen content of the exhaust gases from internal combustion engines or the air-to-fuel ratio  lambda , the method being based on measuring the heat of reaction in the reaction of oxygen with a combustible fluid in a partial flow of the exhaust gas. The mode of operation of the method is as follows: the partial flow of the exhaust gas in an amount of 5 to 100 l/min is cooled to a dew point temperature of down to about 300 DEG C, an amount of the combustible fluid necessary to reduce the maximum oxygen content to be measured is added to the partial flow, the partial flow is then heated to a temperature of about 700 to 900 DEG C within one tenth of the time necessary for reaction, and the temperature increase established in the partial flow after a reaction time of 5 to 100 msec is measured. The temperature increase is a measure of the oxygen content of the exhaust gas. A particular advantage of the method is its insensitivity to harmful components in the exhaust gas.

Title: Device for regulating a working implement mounted on an agricultural tractor
Inventor: DUELL JOSEF
IPC: A01B63/111
Filed: 1982-10-30
Abstract: What is described is a device for regulating a working implement, such as, for example, a plough, mounted on an agricultural tractor, which allows the setting of the operating modes, such as pull regulation, mixing regulation, position regulation and depth regulation, and which is as simple to operate as hitherto known regulating devices of this type. To achieve this, the signals of the position sensor (9) determining the relative position of the plough in relation to the tractor are fed to a regulating member (12). This, when the operating mode "pull, mixing and position regulation" is set, leaves the position signal virtually uninfluenced and, when the operating mode "depth regulation" is set, determines the deviation of the latter from the desired position value. At the same time, the pull signals originating from the plough and determined by a pull sensor (5) are fed to a high pass (13) which transmits only for changes in pull greater than a limit frequency fg = 0.1 Hz. The control valve (2) of the power lift (1) is controlled by a feedback signal mixed in a fixed ratio from the signals of the regulating member (12) and of the high pass (13). <IMAGE>

Title: Plastic dowel
Inventor: SIEBRECHT-REUTER GERD DIPL ING
IPC: F16B13/12
Filed: 1982-11-08
Abstract: A plastic dowel having an anchoring part (4) which has a guide channel running in the axial direction and is split over its length into a plurality of cohesive anchoring segments. Each segment has a depression (18, 19) which originates from the outline of the anchoring part 4 and whose position is rotationally offset around the dowel axis from segment to segment. The length of the depressions (18, 19) are equal to the segment lengths, in the axial direction. The depressions each have an extent in the outline circumferential direction which corresponds to the projection of the guide channel on the outline surface. The anchoring part of the dowel can be injection-moulded without a core needle. The application correspondingly also relates to a tool by means of which the dowel can be produced. <IMAGE>

Title: Cable television system
Inventor: OHNSORGE HORST DR ING
IPC: H04B10/29
Filed: 1982-11-13
Abstract: To transmit a plurality of broadband and/or narrowband signals, for example of a plurality of television and sound broadcast programmes, these signals are converted into n non-overlapping frequency bands (FB1 to FBn), which are converted in each case in an electrical-to-optical transducer (W1 to Wn) into optical signals and are transmitted via n parallel optical waveguides (L1 to Ln) from the head station via a plurality of intermediate repeaters to the subscribers (Ü1 to Üj), where the light wavelengths of the optical signals are approximately identical ( lambda 1). At the subscriber end and, where appropriate, in the intermediate repeaters, the n optical signals transmitted in parallel are combined using optical means (K) to form an optical multiplex signal. This signal is converted in a single optical-to-electrical transducer (OE) into an electric multiplex signal. The tuner (comprising a tuning device, IF amplifier and demodulator) of the receiving device converts the desired signal into a baseband signal (video signal or audio-frequency signal). In the intermediate repeater (ZV) of the lowest distribution level, each of the n optical signals is distributed using optical means (K') among j subscribers or transfer points (Ü1 to Üj) (e.g. j = 16). Since the optical multiplex signal passes through a short optical waveguide path only, modal noise is avoided. <IMAGE>

Patent DE-3243244-A1 (DE)
Title: Positioning drive
Inventor: WEHKING HANS
IPC: G05B19/23
Filed: 1982-11-23
Abstract: A current-limiting signal is applied to a logic circuit, by which current-limiting signal the through-switching of a reduced operating current to a positioning drive has been initiated while said drive is in its quiescent position (B). In the event of erroneous displacement from the quiescent position, the positioning drive generates movement signals (15) by means of a position sensor, which movement signals are likewise supplied to the logic circuit. The logic circuit uses the coincidence of the movement signals (15) and current-limiting signal (B) to produce an error signal (C) which is buffer-stored and results in a search for the basic position before the drive is set into a new position. <IMAGE>

Title: Method and circuit arrangement for the transmission of data signals
Inventor: BADER EDGAR DIPL ING
IPC: H04J3/06
Filed: 1982-12-30
Abstract: It is appropriate in certain cases not to transmit a complete multiplex signal (for example, the complete 64 kbit/s multiplex signal according to CCITT Recommendation X.51) or a single channel, but rather to transmit an individual channel group. A channel group is made up uniformly in each case of k channels in time-division multiplexing, where each channel has the same envelope structure with a permanently allocated sync bit. The channels are arranged in the channel group in envelope-interleaved form. The frame synchronisation information is provided in that k consecutive sync bits in one channel group are identical and in that the sync bits of successive groups in each case with k envelopes are alternately binary >>0<< and binary >>1<<.

Title: Hydraulically actuable appliance for the mechanical disintegration of rock (centring of the thrust jaws)
Inventor: PORSFELD FRIEDHELM
IPC: E21C37/04
Filed: 1982-07-30
Abstract: Hydraulic appliance for the mechanical disintegration of rock, having a cylinder (1), in which a hydraulically actuable piston with a piston rod (3) is arranged so as to be longitudinally movable. Fastened to the free lower end of the piston rod (3) is a sliding wedge (18) which acts on thrust jaws (17) which are insertable into boreholes, laterally displaceable to a limited extent and releasably connected by means of reinforced head pieces (32) to the cylinder block or to a cylinder lower part (2) arranged releasably on this and which have a slope corresponding to the inclination of the sliding wedge (18). The thrust jaws (17) are suspended in the cylinder block or cylinder lower part (2) on diametrically arranged transverse bolts (10) and are fixed and centred elastically by means of spring elements (13, 14). As spring elements for centring the thrust jaws (17) there are two centring bolts (13) which are arranged in the cylinder lower part (2) transversely relative to the longitudinal extension of the thrust jaws (17), are displaceable counter to the effect of prestressed springs (14) and have bent ends (24) which each rest under the effect of the springs (14) on the outer face of a thrust jaw (17). The centring bolts (13) are rotatable about their own axis, so that their bent ends (24) are located approximately parallel to the thrust jaws (17) for the purpose of releasing these. To simplify the handling, the rotation of the centring bolts (13) takes place as a result of the interaction of the bent ends (24) with correspondingly designed control portions on the thrust jaws (17) when these are pulled out of or introduced into the cylinder lower part (2). <IMAGE>

Title: Process and apparatus for separating husk and fruit from oilseed fruits
Inventor: GOTSCH GUENTER
IPC: A23N5/00
Filed: 1983-03-16
Abstract: The process and the apparatus for separating husks and fruits from oilseed fruits, such as nuts, almonds, apricot kernels and the like, wet the husks by a vacuum treatment in such a manner that the air present is removed and is replaced by a separating liquid. As a result of this, the specific weight of the husks increases accordingly, so that in a subsequent separation bath the fruit kernels float and the husks collect on the bottom. As a result, by means of appropriate mechanical devices, clear division and separation is possible, so that the kernels having a high degree of separation can be admitted to further processing.

Title: Exhaust manifold for multi-cylinder motor-vehicle engines
Inventor: KOHL BRUNO
IPC: F01N13/18
Filed: 1983-09-23
Abstract: The invention relates to an exhaust manifold which is intended for motor-vehicle engines and has a plurality of connection pieces leading to the exhaust ports of the cylinder head. It is distinguished, on the one hand, by the fact that it is an integral sheet-steel tube with local branches and that the connection pieces are welded to these branches. On the other hand, it is distinguished by extensional waves formed directly in the sheet-metal wall of the connection pieces and/or the manifold. As a result, it can be produced at a favourable cost while having a high compensation capacity, can be of light weight construction and is suitable for encasing in a heat and noise insulation. Jackets made of metal mesh, netting or knitted fabric can be shaped onto the extensional waves in order in this way to improve noise damping.

Title: Anti-skid protection for motor vehicles in general
Inventor: VENTURINI FRANCESCO
IPC: B60C27/04
Filed: 1983-12-30
Abstract: The anti-skid protection according to the invention for the wheels of motor vehicles, lorries etc. contains a radial ring-like carrier which is to be attached to the hub of the associated wheel with the same bolts which also serve to mount the wheel, and which has a multiplicity of radial guides which are offset with respect to one another in terms of angles, in which guides in each case the leg of a hook element which serves as an anti-skid protection or anti-slip means is guided, which element serves to engage in the transverse direction on the circumference of the tyre of the wheel. The legs of the hook element are connected to springs which endeavour to move them to the centre of the wheel in order to ensure that the hook elements rest against the circumference of the tyre. For the use of the vehicle under normal conditions, the hook elements can be separated from the radial ring-like carrier, if they have been released by the associated springs, without the carrier having to be removed from the wheel.

Title: Process for operating a paper machine, and a paper machine for carrying out the process.
Inventor: BRAUN HEINZ
IPC: D21F11/04
Filed: 1984-01-17
Abstract: The paper machine comprises two endless drainage wires (1, 2) as well as a first headbox (24) and at least one additional headbox (25) to form at least two fibre mats which can be combined above the two drainage wires (1, 2). The drainage wires (1, 2) are guided in a common twin-wire former (A) essentially in the shape of an S over at least one drainage roller (7) against a separating roller (8) at which they separate. To produce a single-ply paper, the additional headbox (25) is taken out of operation, and the first headbox (24) is used to form the fibre mat, which in this case is the only one and which is fed to the twin-wire former (A) at a dry matter content of about 2.5% or less and is drained partially through the upper drainage wire (2). In this way, the paper machine is suitable, without structural modifications, for the production of both a multi-ply paper and a single-ply paper, each of high weight per unit area, and requires minimum standstill times when changing over from one type of operation to the other. <IMAGE>
