Title: Process and device for controlling the thickness of extruded flat films or sheets of thermoplastic
Inventor: HAGEN KARL DIPL ING DR
IPC: B29C48/92
Filed: 1981-02-28
Abstract: In this process measured values and data are recorded by a thickness measuring instrument traversing perpendicularly to the extrusion direction, digitised into pulses and the actual values determined are compared with digitised set point values. At the same time a local transverse profile and a longitudinal profile, temporarily superimposed on said transverse profile, of the flat films or sheets are recorded. In said process, the measurement path is subdivided, parallel to the extrusion direction, into a plurality of zones, correlating with control zones of an extrusion die. A mean thickness value is formed from each accepted zone on the flat films or sheets, is compared with the computed set point values and the result is used in the production process for control purposes. An overall mean value is then generated from the mean values of all zones, this overall mean value is compared with the overall mean value of a previous or subsequent traverse of the thickness measuring instrument and the take-off rate of the flat films or sheets is varied corresponding to the differences ascertained. A device for carrying out the process consists of a slit die which is subdivided, parallel to the extrusion direction of the flat films or sheets, into a plurality of control zones which can be temperature-controlled independently of one another and of a thickness measuring instrument which is traversable perpendicularly to the extrusion direction and is connected to a power setting unit and/or a process computer controlling a take-off device.

Title: Device for automatic headlight adjustment in motor vehicles
Inventor: MISKIN LESLIE
IPC: B60Q1/10
Filed: 1981-03-16
Abstract: A device for automatic headlight adjustment in motor vehicles consists of four sensors which are arranged in pairs one behind the other in the direction of travel on those components of the motor vehicle which respond to loading. The sensors then transmit signals which pass via an analog multiplexer and an analog-to-digital converter into a microprocessor which evaluates the signals, i.e. determines differential values, additionally calculates the mean values from a series of measurements and compares them with a predetermined value. In the event of deviations from this value and when a specific threshold value is exceeded, the microprocessor transmits signals which are fed via digital-to-analog converters with operational amplifiers connected downstream to headlight adjustment equipment and bring about there a correction of the respective associated headlight using corresponding conventional means such as for example servo motors.

Title: Device for feeding workpieces to and removing workpieces from a machine tool
Inventor: HERRMANN EWALD
IPC: B25J5/02
Filed: 1981-04-24
Abstract: In a device for feeding workpieces to and removing workpieces from a machine tool, with a horizontally movable carriage which carries longitudinally movable gripper arms with a gripping head having two pincer elements, the pincer elements are opened or closed by longitudinal displacement of a control rod. The displacement of the control rod required for this is effected by means of a drive which is attached to the carriage and has a link with a link slot in which a link slot made on the gripper arm engages in the bottom end position of the gripper arm, which link slot is rotated through 180 DEG  by the link disc and in the process rotates an eccentric sitting on the control rod, as a result of which the control rod is displaced, for example, in the opening direction of the pincer elements. Upon further rotation through 180 DEG , the control rod is pulled back again and the pincer elements are closed by spring force.

Title: Device for the removal of a charge from electrostatically charged subjects
Inventor: CHRISTOFFERSEN CHRISTEN
IPC: A61N1/14
Filed: 1981-05-07
Abstract: In a device for the removal of the charge from electrostatically charged subjects, the potential difference between the subject and a reference potential is balanced out in that the charge from the affected subject is removed via an electrically conducting gripping part which is touched by the subject, and a downstream discharge path. The gripping part which is designed as a key is mechanically and electrically coupled to the normally open contact of at least one switch connected in the discharge path, and the breakdown voltage determined by the spacing of the open, unactuated switch contacts is chosen to be higher than the maximum electrostatic voltage to be expected and to be balanced out. Each normally open contact can be actuated via the key until the particular switch is completely closed.

Title: Arrangement for lighting a room with roof windows
Inventor: BARTENBACH CHRISTIAN
IPC: E04D3/06
Filed: 1981-06-04
Abstract: For lighting rooms with daylight, direct insolation is undesirable owing to the glare and heating-up of the room which go hand in hand therewith; accordingly, roof windows have been oriented north and set at a slant. However, only midday insolation is avoided as a result. By means of the invention, it is intended that the sun be also fully blotted out during the morning and afternoon. For this purpose, a light shaft (2) with correspondingly dimensioned, parabolic side mirrors is arranged in the window opening (11). The inclination of the inlet opening (20) of the light shaft corresponds to the geographical width and the blotting-out angle ( epsilon ) of the obliquity of the ecliptic. <IMAGE>

Title: Pressure-compensation arrangement for freezing devices
Inventor: WENSELAU GUENTHER
IPC: F25D17/04
Filed: 1981-07-14
Abstract: It is known that cold air escapes or is displaced by penetration of the warm room air when a freezing device is opened. After closing the device door, a powerful vacuum is created by cooling of the warm room air, which prevents the door being opened again in the short term. To eliminate this problem, a pressure-compensation arrangement is introduced into the underside of the door, which is connected to the interior and compensates the vacuum via a rubber lip (see drawing). The rubber lip has the tendency always to return into the starting position and consequently prevents an escape of the cold or penetration of air humidity. The arrangement can be built into freezer cabinets, freezer chests and into the froster compartment doors of a combined refrigerator. <IMAGE>

Title: Precast concrete structural unit and composite wall constructed with it
Inventor: TOFFOLON ROGER L
IPC: E04B2/02
Filed: 1981-07-30
Abstract: The invention relates to precast concrete structural units (10) and to composite walls consisting of these precast concrete structural units (10). Each structural unit (10) comprises two longitudinally directed side walls (12) which are connected to one another by two transversely running connecting arms (18). Push-in connecting means (22, 24) for connecting structural units (10) arranged one above the other in each case comprise a recess (22) on the underside and a complementary extension (24) on the top side of each connecting arm (18). Each recess (22) and each extension (24) have two approximately vertical bearing surfaces (26) pointing in opposite directions and in each case extend over approximately one-third of the overall width of the associated structural unit (10). The longitudinal distance between the connecting arms (18) is twice as great as the longitudinal distance of each connecting arm (18) from the adjacent end of the side walls (12). The structural units (10) can thereby be arranged in vertical alignment or in rows mutually staggered horizontally by half the length of a structural unit, the connecting arms (18) being vertically in alignment with one another while forming chimney-like hollow spaces which can be filled with a filling material to improve the strength of the wall. A composite wall can contain rows of structural units of different widths, structural transition units being arranged between wider and narrower structural units. <IMAGE>
Patent DE-3133564-A1 (DE)
Inventor: BOSCH ERHARD DR
IPC: C08L83/04
Filed: 1981-08-25
Abstract: The invention relates to organopolysiloxane compositions which are stable when stored under anhydrous conditions, but when exposed to moisture cure to an elastomer containing (a) a diorganopolysiloxane having terminal condensable groups, (b) a silicon compound having 3 amino groups bonded to silicon via nitrogen and/or oxime groups bonded to silicon via oxygen per molecule and (c) a silicon compound having at least one thiol group selected from mercapto-functional silanes or siloxanes. The presence of the mercapto-functional silanes or siloxanes substantially retards the formation of skin but does not substantially extend the cure time of the organopolysiloxanes compositions. These compositions are useful in, for example, screen printing, where a long skin-over time is desired.

Patent DE-3137679-A1 (DE)
Inventor: REISS RUEDIGER DR ING
IPC: G10L19/02
Filed: 1981-09-22
Abstract: A synthesizer for a channel vocoder for the transmission of speech with considerable frequency band reduction in digital technology provides a reduction of circuit expense. This is accomplished, given non-recursive filters having finite impulse response, not with a weighting of the pulse-shaped excitation variable with the transmitted envelope values of the spectral channels, but with a time variance of the filters by weighting their filter coefficients with the transmitted envelope values. In addition, with proper dimensioning of the filter coefficients, an optimum speech quality of synthesized speech is obtained at the output of the synthesizer even given elimination of the transmission of a voiced/voiceless signal.

Title: Method for forming a time-division multiplex signal from broadband channels or analog signals
Inventor: ASSMUS ULF DIPL ING
IPC: H04H20/81
Filed: 1981-11-23
Abstract: To keep the operating speed of the electronic components as low as possible when forming a 34.368-Mbit/s time-division multiplex signal from very many broadband channels or analog signals, for example from 24 sound broadcast signals with two signals (L and R), the analog signals (TON 1 to TON m) are digitised in m channel modules (K1 to Km) and are there in each case combined with an associated channel-individual service information (I1 to Im). The bit-parallel data words produced successively pass via a databus (DB) to a central processing unit (ZE). The connection of the channel modules to the databus, which occurs successively in time, is controlled by addresses which reach all channel modules via an address bus (AB) and are generated in the central processing unit (ZE). In the latter, a serial multiplex signal (MS) is generated from the bit-parallel data words after the insertion of channel-independent information such as synchronisation words (Syn), signalling words (Sig), clock time (U) and so forth. <IMAGE>

Title: Trailer brake system
Inventor: MUNCKE LUDWIG
IPC: B60T7/10
Filed: 1981-12-04
Abstract: A trailer brake system with mechanical parking brake and hydraulic power brake is described, the brakes being capable of being released separate from one another. A hydraulic brake cylinder is provided, the piston of which has a power-transmitting connection to the brake linkage of the parking brake. The central actuating element for the trailer brakes is formed both in the case of the parking braking and in that of the power braking and where necessary in the case of breakaway braking by a pushrod, which extends from the trailer to the front end section essentially in the middle of the drawbar plane, in which end section both the hydraulic cylinder and the actuating devices for the mechanical parking brake are arranged. The brake cylinder can be coupled directly to a load adjusting valve, which is also accommodated in this front drawbar section. In this way a trailer braking system is produced, the structure of which can be kept extremely compact whilst achieving all the necessary functions, a minimum of components being required.

Title: Process for the production of hepatitis B vaccine
Inventor: THOMSSEN REINER PROF DR MED
IPC: A61K39/00
Filed: 1981-12-23
Abstract: An improved process for the purification and inactivation of HBsAg from plasma from carriers of hepatitis B virus is described. This material can be employed as vaccine against this virus. The purification process consists of a fractional precipitation with polyethylene glycol, of a zonal flotation by dense salt solutions and of a final gel chromatography. The optimised sequence of these steps permits the HBsAg to be concentrated 5000-fold in 99% purity with a 95% protein yield and 60% activity yield. The use of enzymes, detergents or denaturing agents is avoided thereby. Hepatitis B viruses are attenuated by a factor of 10<4> or more. Any residual infectiosity is eliminated more reliably than hitherto with formalin in the high concentration of 1:450. The HBsAg is adsorbed directly after the inactivation on aluminium hydroxide gel, and the formalin is removed by washing the gel. The resulting suspension of HBsAg-containing gel is a vaccine which is ready for use and whose activity is higher than that of a reference material.

Title: Electric coffee machine with centrifugal filter
Inventor: LEUSCHNER UDO
IPC: A47J31/22
Filed: 1982-02-08
Abstract: The invention relates to an electric coffee machine with a centrifugal filter, to which the infusion water is supplied by means of a conveying device, e.g. to a hollow cone constructed thereon. The aim of the invention is to avoid or extensively reduce unbalances caused by non-uniform distribution of the coffee powder in the centrifugal filter. This aim is achieved according to the invention in that the conveying capacity of the conveying device, the actual filter, e.g. in the form of a filter gap, and the filter geometry are adapted to one another in such a manner that, when fine-ground or medium-ground coffee powder is used, an infusion-water build-up takes place in the centrifugal filter which reaches inwards to in front of the coffee powder layer and expediently fills the entire filter interior. <IMAGE>
Patent DE-3208988-A1 (DE)
Title: Deburring tool
Inventor: KRISCHKE STEFAN
IPC: B24B9/00
Filed: 1982-03-12
Abstract: The deburring, i.e. the final treatment of sheet edges and other flat-material edges, is still a very complicated and costly matter. By the use of so-called cup brushes for deburring flat parts, it becomes possible to deburr both the top and bottom edge in one operation. To this day it has been a problem time after time for the person carrying out the treatment to determine the edge provided with the cutting burr. In particular in the case of mass-produced punched parts which for the most part have been located in a collecting container, it has been exceptionally difficult to work without problems using the previous deburring devices and tools. In addition, this novel brush deburring technique ensures that no additional primary burr from the deburring tool builds up after the deburring operation.
