Title: Process and apparatus for producing a profiled bar from thermoplastic material
Inventor: BRUNNHOFER ERWIN
IPC: B29C48/157
Filed: 1987-12-15
Abstract: Process for producing a profiled bar from thermoplastic material with a plurality of auxiliary components of another material embedded in an ordered manner, the thermoplasticised material being extruded with the aid of an extruder which has a shaping hot die piece and a calibrating cold die piece and also a continuous shaping and calibrating channel. The auxiliary components are introduced into the thermoplasticised material and embedded in it. The auxiliary components, which are of a length which is not quite equivalent to the height of the shaping and calibrating channel, are introduced transversely to the axis of the shaping and calibrating channel into the continuous stream of thermoplasticised material in cycles, to be precise in the region of the transition between the hot die piece and the cold die piece. Thereafter, the auxiliary components are taken along by the stream of thermoplasticised material and guided directly at the channel walls running transversely to the direction in which they are introduced, or with a thin layer of plastic interposed. An apparatus for carrying out the process is also specified. <IMAGE>

Title: Method and apparatus for determining the air rate
Inventor: SCHULTE ERASMUS DIPL PHYS DR
IPC: F02D41/18
Filed: 1988-01-28
Abstract: In the determination of the air rate by means of a measuring bridge, the current flowing through the air-current measuring resistor at bridge balance is normally taken as a measure for the air rate. If, in critical working ranges, especially when beginning at low temperatures, there is not a sufficient reserve in the bridge supply voltage available for the measuring bridge and thus a bridge balance is not achievable, considerable measurement errors result. These can be avoided in that the bridge differential voltage is compared with a threshold value and that, in the case of overshoot of the threshold value, there follows a switching-over to an evaluation at constant supply voltage. In this way, a different evaluation or assessment of the measured value corresponding to the current is carried out when the bridge differential voltage is smaller than or greater than the threshold value. It is furthermore possible not only to evaluate the current flowing through the air-current measuring resistor as a measured value, but also to form, from this and from the bridge differential voltage, a corrected measured value which is then evaluated or assessed differently, depending on whether the bridge differential voltage undershoots or overshoots the threshold value. In this way it is possible to measure the air current sufficiently accurately, even if the voltage reserve for balancing the measuring bridge is no longer sufficient.

Abstract: A device for filleting fish comprises a cutting blade 112 mounted between a pair of parallel legs 114,116, the legs being rigidly connected to a base portion 117 opposed to the blade 112. To fillet a fish, a cutting edge 140 of the blade 112 is inserted behind a gill of the fish, and the tool is then drawn rearwardly towards the tail to sever the fillet which passes between the blade 112 and the base portion 117. The length and curvature of the blade 112 can be adjusted to conform to the thickness and roundness of the fish. <IMAGE>

IPC: B66C13/08
Filed: 1988-03-11
Abstract: A manipulating appliance for gripping and moving objects is proposed which has a receiving device on a parallelogram boom. The parallelogram boom has two links roughly parallel to one another. The links are each linked with one end to a holder and with their other end to the receiving device. Furthermore, a load-balancing device with a working cylinder is provided between the holder and at least one link. This link has at least one supporting arm projecting transversely at the articulation point and fixed thereto. The supporting arm runs roughly parallel to at least one connecting member linked at a distance therefrom to the holder. The supporting arm and the connecting member are connected via at least one coupling member at the free end to form a parallelogram which can be moved by the working cylinder and acts on the link. The working cylinder is supported on the one hand on the holder and on the other hand on the coupling member of the parallelogram. Weight relief is thereby achieved in a simple manner. <IMAGE>

Patent DE-3812383-A1 (DE)
Inventor: DRINDA KLAUS DIPL ING
IPC: H03C3/09
Filed: 1988-04-14
Abstract: A keyed retuning method for FM-modulated signals and arrangement. When signals are modulated which are not free of average values, for example D2-MAC signals, there must be no falsification of the signal or control of the centre frequency as a function of the direct component of the modulating signal. During the processing of a retuning signal for a modulator (MO) by comparing the frequency and phase (PD) of a modulation signal (SM) with a reference signal (SR), the frequency/phase comparison (PD) is suppressed for the period in which the signal component is not free of average values. The method and the arrangement are suitable, in particular, for AFC-controlled D2-MAC-capable FM modulators without disturbing the carrier energy dispersal. <IMAGE>

Title: Apparatus for the production of foundry moulds
Inventor: DAMM NORBERT ING GRAD
IPC: B22C9/12
Filed: 1988-05-28
Abstract: The invention relates to an apparatus for the production of foundry moulds, the moulding material being tipped loosely into a mould cavity to cover a pattern plate with a pattern, after which it is compressed and cured chemically by passing through it a reaction gas. The important point is that the reaction gas fed to the moulding material from above is extracted in the region of the pattern plate. This ensures rapid and complete penetration of the reaction gas into the interstitial voids in the moulding material.

Abstract: The invention starts from a clarifying thickener for treating a suspension comprising a liquid and solids, to which suspension flocculents are added as required, the solids settling out from the liquid by sedimentation to form a sludge bed in the bottom region furnished with a rotatable rake mechanism (8) of the clarifying thickener constructed in the manner of a vessel, the outlet orifice (15, 16) of the suspension feed being arranged centrally to the vessel wall of the clarifying thickener beneath the sludge bed surface (10) and broadening outwards in a radial direction uniformly over its entire circumference in the outflow direction of the suspension. In order to ensure as uniform as possible and vortex-free distribution of the inflowing suspension in all radial directions and as complete as possible a separation of the solids from the suspension on flowing through the sludge bed, it is provided that the rake mechanism (8) having upwardly projecting rods, lugs or the like (22) engages in the space between the outlet orifice (15, 16) and the wall (17) of the clarifying thickener in the suspension stream moving radially outwards to equalize and dewater this suspension stream. <IMAGE>

Title: Method for trigger pulse control
Inventor: WAEGNER HANS-JUERGEN DIPL ING
IPC: H03K17/13
Filed: 1988-07-30
Abstract: The invention relates to a method which is used for phase-gating and zero-crossing control in integrated circuits. The object of the invention is to find a method for trigger pulse control which allows phase-gating control or zero-crossing control to be implemented, using a single basic layout, by minor variation of the conductor path plane, and allows the disadvantage of known phase-gating control to be overcome. The object is achieved according to the invention in that the Q output of the RS flipflop must continuously carry an H signal for the entire switched-on duration when switched on and when the operating voltage monitor or pulse inhibitor is switched off, even during zero crossings. The RS flipflop is not reset by the zero-crossing detector, and the Is current sink switched on, until the operating voltage monitor or pulse inhibitor has been switched off.
