Title: DC-DC converter with an inductive store
Inventor: KUPKA DETLEF DIPL ING
IPC: H02M3/335
Filed: 1982-07-13
Abstract: A DC-DC converter with an inductive store, with a charging capacitor and with a constant-current regulator for regulating the current emitted by the output circuit to a load. In such a DC-DC converter it is intended to ensure that, without any adverse effect on the stability of the control loop, a load which is additionally connected to the output has as little effect as possible on the accuracy of the current regulation. To this end, the invention provides that the desired value output of the actual value/desired value comparator is passed via a resistor to the connection of the charging capacitor facing the actual value transmitter and that the internal impedance of the desired value transmitter has a value other than zero.

Patent DE-3227780-A1 (DE)
Title: System for the digital transmission of video or videotelephone signals
Inventor: SANCTIS MASSIMO DE DR ING
IPC: H04N7/54
Filed: 1982-07-24
Abstract: The invention relates to a system for the digital transmission of the video or videotelephone signals with a bit rate of a PCM quaternary system of 139,264 Mbit/s according to CCITTG703, in which the analog video or videotelephone signal is coded to a bit rate of 135 Mbit/s, and is characterised by inexpensive synchronous multiplexers and demultiplexers at the transmitting and receiving end of the subscribers or the broadband exchanges, with 64-kbit/s spacing. An advantageous factor is the modular construction which allows any and arbitrary changing combinations of different narrow-band signals to be additionally transmitted. Furthermore the absence of the delay time jitter occurring when stuffing is used in the exchange, the minimum queuing memory required and that for the detection of signalling in the exchange only the signalling channel needs to be separated from the broadband/narrow-band multiplex signal and fed back to it are also of advantage, whereas the multiplex signal must be split completely into its individual signals and reassembled when the stuffing/multiplexing technique is used.

Title: Arrangement for a roller shutter with strap actuation as well as clamping device for this
IPC: E06B9/324
Filed: 1982-08-25
Abstract: In a roller shutter actuated by a strap (26) which is coiled in a strap winder (28) under the shutter box (12) and which, in particular when the roller shutter (16) is raised, can be secured in a clamping device (30), opening automatically when actuated again, by letting go of the strap (26), the clamping device (30) is arranged at a distance above the strap winder (28) which is adequate for taking hold of and actuating the strap (26). This ensures that the roller shutter (16), after its actuation, remains in the position achieved as a result, in particular the sealing position at the top end, and the slight lowering again which occurred previously is also avoided without taking particular care. The clamping device (30) can be attached to the storey frame (10) or the adjacent wall reveal; alternatively, it can also be attached to the strap lead-through of the shutter box (12). <IMAGE>

Title: Method and device for removing solid components from the exhaust gas of internal combustion engines, especially soot components
Inventor: LINDER ERNST DIPL ING
IPC: F02D21/08
Filed: 1982-09-29
Abstract: A method is described for removing solid components, especially soot components, from the exhaust gas of internal combustion engines, in which two exhaust-gas part-flows are produced with the aid of a separating device, one of these part-flows being enriched with solid components and the other being largely freed of solid components. The enriched part-flow is recirculated to the intake side of the internal combustion engine in selected operating states, e.g. part load, via an exhaust-gas recirculation line (10). To control the exhaust-gas recirculation flow, a valve (11) is provided in the exhaust-gas recirculation line. The valve can be operated simultaneously with a valve (20) which controls a bypass line (17) of a filter (15) connected upstream of the separating device (6). The filter (15) is only connected up in the case of full-load operation and, due to its arrangement close to the exhaust side of the internal combustion engine, has the characteristic of burning itself free of the filtered soot components during operation. <IMAGE>
Patent DE-3236253-A1 (DE)
Title: Method and device for shrinking a film wrap on a stack of piece goods on a pallet
IPC: B65B53/06
Filed: 1982-09-30
Abstract: The invention relates to a method and also to a device for shrinking a film wrap on a stack of piece goods on a pallet. In order to achieve a firm shrinkage tension and thus adequate fixing of the stack of piece goods on the pallet, it is traditionally necessary to employ thick plastics films to which large quantities of heat need be applied for shrinking purposes. Nevertheless, such films under tension are ineffective when damaged, because the tension is then no longer there. The possibility also exists of wrapping a length of film around in a number of layers; this, however, means that the shrinkage tension is less because only the outer film layer is subjected to the shrinking action. In every case, a procedure is followed in which the stack is first of all completely wrapped and then shrunk by the action of heat. The method according to the invention provides a departure from this in that heat is applied within a winding-round sector lying between 90 DEG  and 270 DEG . This permits each film layer to be individually shrunk, whereby the shrinkage tensions are superimposed and hence a particularly firm strapping of the shrink-wrapped pile achieved. In this way, it is possible for improved packings with a lower film mass to be produced.

Title: Universal small-waste pressing device for making briquette-shaped blocks of refuse for burning
Inventor: HELLER HEINZ DIPL ING
IPC: B30B9/06
Filed: 1982-11-20
Abstract: With the aid of the universal small-waste pressing device, a block of L = 23.5 cm, B = 9.5 cm and H = 5-7 cm is produced. As a result of the simple operation - without great force and skilfulness - with the aid of rapid fastening of the device on a suitable tub, a complete working unit is formed, which makes possible efficient working. The lifting jack is also easy to separate from the press, so that tub and lifting jack can be used for other work as well. These parts are anyway already available in many cases and can be integrated. By combining the complete device with a suitable garden chopping device and an efficient drying stand, a system is produced, which can, without great work outlay, to a great extent use domestic, garden, industrial and office waste.
Patent DE-3244014-A1 (DE)
Inventor: BERGER JOHANN
IPC: D04B25/06
Filed: 1982-11-27
Abstract: Crochet tools for producing bands on a crochet galloon machine. For the production of thin bands on ten or more crochet needles (10, 10') per centimeter of width, the stems of the crochet needles (10,10') are clamped over more than half the length of the needle. A knocking-over bar (20) fastened to the machine has a free straight edge (66) which adjoins closely but without play those parts of the crochet needles (10,10') which project out of the clamp device. The crochet needles are clamped with adequate security against lateral bending. There is no friction between the crochet needles at the knocking-over bar (20). The crochet needles can be clamped in groups, so that they stiffen one another. For the feeding of elastic threads use is made of combs (6) which are displaced laterally to-and-fro relative to the crochet needles in the working rhythm, but which are disposed at a uniform height relative to the crochet needles.
Patent DE-3244170-A1 (DE)
Title: Device for controlling the air humidity
Inventor: NORDMANN JACQUES
IPC: F24F11/00
Filed: 1982-11-29
Abstract: In a room (R1), a hygrostat (2) and an air humidifier (4) are arranged in such a manner that the air humidifier (4) is switched on and off by the hygrostat as required. For this purpose, the hygrostat (2) is provided with an infrared transmitter (6) which radiates every minute a modulated command pulse (S) which is received by the receiver (5) of the air humidifier (4) and forwarded to the air humidifier. Depending on the pulse modulation (on/off) determined by the hygrostat contact, the air humidifier is thus switched on or off. Should the transmitter fail, the humidifier is switched off after a certain waiting time and a fault indicator is switched on. Furthermore, a third modulated command pulse is provided which signals the end of the transmitter battery life. The main advantages of the device lie in the omission of the transmission cable hitherto required between hygrostat and humidifier, and in the great operational reliability. <IMAGE>
