Title: Head rest for motor-vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/48
Filed: 1981-02-10
Abstract: The head-cushion support of a head rest for motor vehicles has a bearing arrangement for adjusting its inclination. This bearing arrangement is essentially composed of a plastic sleeve with integrally formed bearing journal and of a clamping bearing clip. This bearing arrangement has improved the invention, for obtaining uniform frictional ratios even in the case of extremely high internal temperatures, in that there is formed, between the inner surface of the slotted tubular region of the clamping bearing clip and the bearing journal, an essentially circular annular space which is filled by a metal bearing sleeve coaxially surrounding the bearing journal. The bearing sleeve is secured against concomitant rotation.

Title: Hollow purpose-made block
Inventor: MACULAN ALEXANDER DIPL ING DR
IPC: E04C1/41
Filed: 1981-05-08
Abstract: In a hollow purpose-made block, insulating inserts in the form of panels can be introduced into cavities intended for this purpose and they are held in a frictionally locking manner in said cavities such that air-filled cavity portions remain on at least one longitudinal side of said insulating inserts. In order to improve the securing of the insulating inserts in the cavities and to protect said inserts from damage when pushing them into the cavities, the invention provides that the cavities at the level of one of the two bearing surfaces of the hollow purpose-made block narrow, for the purpose of securing the insulating inserts, to a width corresponding to the cross-section thereof, but exhibit a larger cross-section at the remaining level in order to form the cavity portions which are desirably filled with air. This measure brings about the additional advantage that one of the two bearing surfaces of the hollow purpose-made block is closed over its entire surface and can be used as carrier for a mortar bed without there being a danger of mortar falling into the cavities, used for insulation, and impairing the insulating effect thereof.
Patent DE-3120639-A1 (DE)
Title: Arrangement for adaptive cancellation of talker echoes
Inventor: HESPELT VOLKER DR ING
IPC: H04B3/23
Filed: 1981-05-23
Abstract: The invention relates to an arrangement for adaptive cancellation of talker echoes in duplex data transmission via two-wire links, the compensating signal being extracted from the received signal, the remaining residual signal being used together with the transmission data to set the coefficients of the echo canceller and the compensating signal being formed at a high rate. Currently known interpolating echo cancellers incur high cost. The object of the invention was therefore to reduce this cost. This is achieved according to the invention in that the echo canceller emits compensating values at a low rate, the required intermediate values are formed with the aid of an interpolator and the effect of the interpolator is taken into account when the echo canceller coefficients are set.

Title: >>Frequency-modulation-capable radio-frequency oscillator circuit<<
Inventor: FRANKE MANFRED
IPC: H03B5/36
Filed: 1981-06-23
Abstract: A frequency-modulation-capable radio-frequency oscillator circuit for radio devices is proposed which has a relatively substantial modulation depth with a low modulation voltage. The oscillator circuit comprises an inverter stage (10) of an integrated MOS or MOSFET circuit (33) whose output (12) is connected via a series circuit comprising a resistor (13), an adjustable inductor (14) and an oscillating crystal (15) to the input (11) of the inverter stage. A series circuit comprising a capacitor (26) and a parallel resonant circuit (27) is disposed between the output (12) of the inverter stage and earth. A further series circuit comprising a capacitance diode (21) and a resistor (22), with which a capacitor (23) is connected in parallel, is connected at a first connection point (20) between the resistor (13) and the adjustable inductor (14) of the first-mentioned series circuit and earth. A second connection point (30) between the capacitance diode and the associated resistor is connected to a terminal (25) to feed in the modulation voltage (UMod). As an alternative, the required bias voltage can be fed separately to the capacitance diode (21), i.e. independently of the DC operating voltage (UDD). <IMAGE>

Patent DE-3142525-A1 (DE)
Title: Heat store
Inventor: JOVY HERBERT DR
IPC: F28D20/02
Filed: 1981-10-27
Abstract: A number of support cylinders (9) are inserted in a container (2). Each support cylinder (9) is formed from a helically wound steel plate having self-overlapping rims, which are welded to one another. Each support cylinder (9) is formed by a likewise helical fluid duct (10) made from a shaped piece (17). This shaped piece (17) is welded to the support cylinder (9) on longitudinal strips (20). It has a spacer (21), which centres the cylinders (9) with respect to one another. Furthermore, this spacer (21) ensures there is no undesired thermal circulation of the storage medium present in the container. The storage medium can be a saturated fatty acid. Production of the cylinder (9) and fluid duct (17) is performed in one operation. In this process, two sheet-metal strips are helically wound, one first being rolled to form a shaped piece (17) and welded directly thereafter. The result is an exceptionally inexpensive production of the heat store. <IMAGE>

Title: Coupling hook for a screw coupling on rail vehicles
Inventor: MUELLER GERARD
IPC: B61G1/22
Filed: 1981-11-06
Abstract: A coupling hook (1) for a screw coupling on rail vehicles has a draw bar eye (1a) which is turned away from a coupling hook head via a coupling hook shaft (1b) and which, by means of a bolt, is connected in an articulated fashion to a head part (5) of a vehicle-side spring device (2) which receives the tensile forces which occur. In order to be able to couple the coupling hook (1) in a simpler and more reliable manner and with less risk of accidents, the coupling hook (1) is tensioned counter to the force of a spring arrangement (3) which engages on it, is supported on the vehicle-side spring device (2) and is constructed as an element for centre-restoring the coupling hook (1). <IMAGE>

Title: Flux determining device for the field-oriented control of a rotating-field machine
Inventor: NAKAHARA KAZUHIRO DIPL ING
IPC: H02P21/00
Filed: 1981-11-06
Abstract: At least the direction of the machine flux is calculated in a flux determining device for the field-oriented control of a rotating-field machine. This calculation takes place on the one hand by calculation modelling of the machine dynamics, based on the machine currents (i tau 1, i tau 2) ("current model"), and on the other hand is calculated from the e.m.f., by integration of the machine voltages (U alpha , Uss) ("voltage model"). At low rotation speeds, the integration in the voltage model is inaccurate and the current model provides the direction value required by the controller. At relatively high rotation speeds, the difference between the two direction model values ( psi 1,  psi v) is formed and is connected via a regulator (2) to the current model (20), by closing a switch (3), so that the direction of the flux calculated in the current model is slaved to the direction supplied by the voltage model. In consequence, at relatively high rotation speeds, the current model is provided with the dynamics of the voltage model, without discontinuities occurring during the changeover. <IMAGE>

Patent DE-3147481-A1 (DE)
Title: Electronic microcomponent and process for producing it
Inventor: WIRTH WERNER
IPC: H01L23/544
Filed: 1981-12-01
Abstract: Passive and active electronic components are mass produced by forming a multiplicity of individual components simultaneously on or in a substrate. The components are left in this substrate array until they are electrically tested and electrical connections are then made. Components found to be defective during electrical testing are marked by applying marking ink. To prevent perfect components in the vicinity of the defective component also being marked by the marking ink as it spreads, a barrier is produced around the component on one of its principal faces. The barrier projects above the surface of the component by 1 to 10  mu m and thus forms the edge of a basin for the marking ink. <IMAGE>

Patent DE-3201307-A1 (DE)
Title: Ram-guard profiled decorative strip with aluminium insert and high-gloss anodised visible or bare region
Inventor: MAYER GERT
IPC: B60R13/04
Filed: 1982-01-18
Abstract: The present invention is concerned with the production of ram-guard decorative strips with moulded-in high-gloss anodised aluminium insert. In the case of such strips, produced by the extrusion process technique, fine hairline cracks occur in the anodised oxide layer due to high temperatures and, furthermore, the surface is likewise damaged by scratching, and consequently premature corrosion is encouraged, when subsequently cutting the so-called visible region free from the plastic. The problem is solved by now using the injection-moulding process instead of previously the extrusion process to produce the strips and by laying the shaped high-gloss anodised aluminium profiles into a mould and encapsulating them. The visible region is kept free from the hot injection-moulded polymer melt by appropriate designing of the mould, in order to keep the temperature as low as possible in this section. If this technique is applied, the ram-guard decorative strip, used predominantly in the automobile sector, does not exhibit any hairline cracks or scratches on the surface of the visible region. A novel adhesion promoter having an activation temperature of about 140 DEG C is used for bonding the plastic and aluminium profile.
Patent DE-3211535-A1 (DE)
Title: Air gun
Inventor: TAYLOR HUGH FRANCIS
IPC: F41B11/647
Filed: 1982-03-29
Abstract: An air gun has an ignition mechanism consisting of a gas chamber of variable volume located behind a piston which is itself displaced in an outer cylinder in front of a rear cylinder. The gas chamber is located between the piston and the rear cylinder and is surrounded so as to be sealed off. When the gun is cocked, the piston is locked in its rear position, in which the gas located in the chamber is compressed to the greatest extent. The trigger releases the piston lock and causes the piston to be driven forwards, whilst the gas in the chamber of variable volume expands and the air in the outer cylinder is compressed in front of the piston, until a limit value forcing the bullet out of the loading space is exceeded. The semi-permanent gas charge in the chamber thus constitutes a pneumatic spring. A safety device is provided and relieves the pressure in the chamber before the ignition mechanism can be dismantled.
Patent DE-3215486-A1 (DE)
Title: Wave generator for ocean waves
Inventor: BSCHORR OSKAR DIPL ING DR RER
IPC: F03B13/18
Filed: 1982-04-26
Abstract: The object is to convert the energy of ocean waves into mechanically useful energy. To this end, buoyancy bodies are attached eccentrically to a flexurally rigid spindle and offset helically over the spindle length. The entire arrangement is orientated floating on the water surface and in the running direction of the ocean waves or at an angle to them (Fig. 1). The pitch of the helix is here the same as the average wave length of the ocean waves. In a wave field, the buoyancy bodies experience moments in the same direction and thus drive the rotary spindle. For a uniform power output it is convenient for the rotary spindle to be made longer than the wave length of the ocean waves.
