Patent DE-3212245-A1 (DE)
Title: Method for manufacturing a heat-insulating building element
Inventor: GUT MAX
IPC: E04F13/04
Filed: 1982-04-02
Abstract: For manufacturing a heat-insulating building element from a thermoplastic foam with good surface adhesion to plaster material, in particular to lime-cement plaster, a grid of recessed grooves is produced in the surface of the building element (10) through the action of heat. A wire net (20) is preferably inserted in these grooves as reinforcement. The grooves are then filled with concrete, so that a grid of concrete ribs (22) results. Through subsequent further action of heat on the surface, recessed surface regions (24) having an irregular surface with good grip result between the concrete ribs (22). The building element has good adhesion to the plaster and high strength. It can be fixed permanently and in a manner capable of bearing loads and is inexpensive to manufacture and attach. <IMAGE>

Title: Antimicrobially treated textile article
Inventor: MORRISON WILLARD L
IPC: D06M16/00
Filed: 1982-04-23
Abstract: A particular fabric, especially double fabric, having a rearside layer or inner side and a front-side layer or outer side. At least one of the layers or sides is at least partially prepared from threads formed from synthetic fibres containing an antimicrobial agent. In some embodiments a connection thread connects the two sides in a plated relationship. Even with minimum contact of the threads in the two layers of fabric the antimicrobial agent migrates from the interior of the treated fibres in one layer to the surface thereof and passes over into the threads in the other layer of fabric. This imparts antimicrobial protection to both layers of fabric, whereas the advantages of natural untreated fibres are retained in one of the layers of fabric.

Title: Temperature control electronics unit for soldering irons
Inventor: FALSE DIETER DIPL ING
IPC: G05D23/24
Filed: 1982-09-29
Abstract: The invention relates to a temperature control electronics unit for soldering irons. The object of the invention is a simple and functionally reliable temperature control electronics unit, which is constructed using a minimal number of components, entirely from standard components in the minimum possible space, which transmits no radio-frequency interference radiation and has no negative influence on the temperature response and parameter tolerances of the components used. The object is achieved according to the invention by decoupling the supply voltage fed to the control electronics unit into the reference voltage required for a comparison network, the reference voltage for the comparison network being generated by a light-emitting diode. The control electronics unit compares the resistance (increasing with the temperature) of the temperature sensor resistor fitted in the vicinity of the soldering tip with a preselectable nominal value and switches the heating element off when the soldering tip reaches the nominal temperature, and on again when it is less than said nominal temperature. The temperature control electronics unit is used for temperature control of electrically heated soldering irons for soldering thermally and electrically sensitive components and electrical technology/electronic components.   <IMAGE>

Title: Control device for the controlled output of bulk material which can flow, especially of liquids
Inventor: ALM HEINRICH-WILHELM
IPC: G01F25/00
Filed: 1982-10-04
Abstract: The invention relates to a control device for the controlled output of bulk material which can flow, via output devices in containers, by means of which the bulk material can be output for a time which can be predetermined. The object of the invention is on the one hand to simplify the calibration process, which is known per se, and to be able to carry it out more precisely, and on the other hand to reduce the output times and the risk of frothing over. To this end, a first calibration device is provided to determine an output time as a calibration time for a predetermined quantity. A measurement device determines the respective actual output time and a comparator compares the actual output time with the calibration time in order to interrupt an output process when the two times are equal. The measurement device and the calibration device are controlled by signals allocated to output phases to determine the times for the output phases and for the overall output time. A second calibration device measures and stores times of successive output phases and output pauses of a calibration output process. The output signals of this second calibration device which correspond to the output phase/output pause sequence control the output processes. The comparator compares the calibration time with the output phase times of an output process, which are added up by the measurement device. <IMAGE>

Title: Arrangement for expelling liquid droplets
Inventor: HEINZL JOACHIM PROF DR ING
IPC: B41J2/04
Filed: 1982-12-07
Abstract: In a print head for ink printer devices with nozzles (1) arranged in rows, for the expulsion of individual ink droplets each nozzle (1) is assigned an electromagnet (5, 6) and an armature part constructed as a tongue (3); the tongues (3) are constructed as teeth of a comb (4) which are located with their free ends directly in front of the inlet opening of the nozzles (1); when the electromagnet (5, 6) is excited, the tongue (3) assigned to it is lifted off from the nozzle (1); after the electromagnet (5, 6) is switched off, a rapid return movement of the tongue takes place, as a result of which an ink droplet is expelled (Fig. 1). <IMAGE>
Patent DE-3304066-A1 (DE)
Title: Variable folding machine
Inventor: GRUEGER CHRISTIAN
IPC: B65H45/18
Filed: 1983-02-07
Abstract: The invention relates to a variable folding machine, comprising a basic assembly and a downstream folding assembly which comprises a plurality of folding units and which can be arranged in various positions in relation to the basic assembly. It is the aim of the invention to simplify coupling of variable folding assemblies with the drive system of the basic assembly, including their synchronisation. The object is to modify the folding blade drive of the variable folding assembly in such a way that the latter can be coupled and fully adjusted regardless of the direction of rotation of the power take-off shaft of the basic assembly. This is achieved by connecting the folding blades of two blade folding units in the variable folding assembly with their common drive via slider-crank mechanisms in such a way that they simultaneously adopt one of their two dead centre positions. A change in the direction of rotation of the folding blade drive shaft does not thereby have a phase-shifting effect on the sequence of movements of the folding blades, and so the set relationship between the folding blades remains the same for left-handed and right-handed running. The variable folding assembly can therefore be fully set and coupled with the basic assembly as required. <IMAGE>

Title: Circuit arrangement for generating a DC control voltage dependent on an AC voltage
Inventor: WIEDENROTH BERND ING GRAD
IPC: H03G11/00
Filed: 1983-02-21
Abstract: The invention relates to a circuit arrangement in a compander system for generating a DC control voltage dependent on an AC voltage which contains a dual time-constant changeover. In order to suppress short-term click interference, only one first sub-capacitor is charged. At the end of the channel interference, the first sub-capacitor is again quickly discharged by transferring the charge to the second sub-capacitor, which is greater by a factor of 10 and is decoupled by a resistor. With a useful signal increase, the charge current of the second sub-capacitor is limited below a first signal value to a first low charge current value and is limited above the first signal value to a second higher charge current value. This limitation to the second charge current value can occur immediately or in constantly changing fashion.

Title: Collapsible and height-adjustable underframe, in particular for all types of tables, stools or the like
Inventor: REGEN REINHARD
IPC: A47B3/02
Filed: 1983-08-02
Abstract: The invention relates to a collapsible and height-adjustable underframe, in particular for all types of tables, stools or the like, which underframe consists of two intersecting pairs of legs, connected to one another in an articulated manner, and is to be mounted on the underside of a table top or the like so as to be swivellable or rotatable and displaceable. In the underframe proposed according to the invention, only the legs of one pair of legs are connected to one another by at least one groove to form a frame which is resistant to rotation and bending, whereas the individual legs of the other pair of legs are connected to the legs of the frame-type pair of legs in each case via a hinge pin which is resistant to bending. Due to this type of design of the underframe, complete freedom for the legs and knees of the user is achieved between the legs of the underframe and, at the same time, a particularly space-saving and careful stackability of the tables or the like equipped with the novel underframes.

Title: Device for removing particles of dirt or air from an ink-jet print head of a printing unit
Inventor: SICKING HEINRICH ING GRAD
IPC: B41J2/165
Filed: 1983-09-17
Abstract: In ink-jet printing units having the smallest outlet nozzles required for producing very small ink droplets, there is a risk of these nozzles becoming blocked by foreign bodies. This blocking can also easily occur due to ink having dried in the nozzles or having decomposed due to ageing. Furthermore, in ink-jet print heads, entry of air bubbles must be avoided since these prevent ejection of ink droplets from the outlet nozzles. The risk of the outlet nozzles becoming blocked is even greater in ink-jet print heads having a plurality of ink chambers which contain inks of different colours. The invention is based on the object of providing a device for removing particles of dirt or air from ink-jet print heads producing multi-colour recordings, which device has a simple construction, is simple to operate, and is suitable for inexpensive mass products. This object is achieved in that the supply hoses 17, 18, 19, which connect the ink-jet print heads to ink supply containers 14, 15, 16 in terms of flow, rest with one portion 25, 26, 27, 28 in each case on an inside wall 29 of a pump housing 30, arranged parallel to one another in the longitudinal direction. Said portions 25, 26, 27, 28 can be subjected separately to a squeezing device 31, advancing in the longitudinal direction, it being possible for a pressure roller 35 to be set selectively on one portion 25, 26, 27, 28.
