Patent DE-3048137-A1 (DE)
Title: Forming strip of plastic bags by perforations, cuts or welds - using clamp bars on endless chains and positive loop forming feed mechanism
Inventor: MEULEN LEONARD VAN DER
IPC: B31B23/00
Filed: 1980-12-19
Abstract: The mechanism is intended for welding and/or perforating or cutting etc. of a continuous double layer or flat tube of thermoplastic material, e.g. in the prodn. of a continuous length of plastic bags. The material is fed with adjustable speed to the entry of a treatment area formed by two sets of endless chains or the like which carry cross-bars to clamp the material between them. The chains move at a slower speed than the feed so that loops are formed between pairs of bars. A rotating guide roller is arranged just before the entry which comes into contact with the material to support and move it during each loop forming cycle. Used in mfr. of continuous length of plastic bags connected via perforations (or individual bags by cutting such continuous length). The process, which employs the forming of loops in a flat plastic tube, overcomes the problems caused by inconsistent loop formation due to differences in the plastic material used.
Patent DE-3049165-A1 (DE)
Title: Electrically operated air flow regulator - for controlling fuel mixture supplied to engine at low or idling speed
Inventor: GRIMM GEROLD
IPC: F16K31/06
Filed: 1980-12-24
Abstract: The electrical actuator for the valve comprises a magnetic yoke (5) carrying a coil (8), and an armature (13) which moves axially w.r.t. the coil. At the base (6) of the yoke cylinder (5) there is a hole in which a guide pin (7) is permanently fixed. The armature (13) runs on this pin through low friction bearings (12). The armature is connected to the slider (14) of the valve assembly. The housing (17) of the latter is typically also support supported on the guide pin, and sealed to both the yoke assembly and the valve casing (1,24). When the coil is energised, the slider position varies the opening (35) between the inlet (2) and outlet ports of the valve. The armature acts against a spring which holds the valve open when the coil is not energised. The arrangement exhibits low mechanical hysteresis and very low leakage in the closed state.

Title: Suction mat for vehicle emergency braking - has holes connecting suction source with suction channels in contact with road surface
Inventor: RICHTER HORST
IPC: B60T1/14
Filed: 1980-12-31
Abstract: The emergency braking system for preventing a vehicle collision, consists of a flexible mat which is lowered into contact with the road surface to act as a brake. This mat is of resilient material with a large number of holes through it, forming a connection between a pattern of suction channels and a suction tube. The resilience of the mat enables it to conform with the shape of an uneven surface to maintain good contact. The mat has a set of parallel tension strips attached to the tips of pneumatic tubes along the upper surface of the mat. Water can be distributed from the channels to form a good seal with the road surface. The suction system is shaped to ensure max. efficiency. An alternative design uses piston and cylinder devices to keep the mat in position.

Title: Handle-fastening device, in particular for household appliances and garden implements
Inventor: KOLB WALTER
IPC: B25G3/18
Filed: 1981-08-03
Abstract: In a handle-fastening device, consisting of coupling sleeve and push-in pin which are fastened to handle and the tool respectively, the push-in pin of rectangular cross-section is locked inside the insertion hole of the coupling sleeve by an offset portion of a leaf spring dropping into a locking hole in the push-in pin. This positive locking can be triggered by a handle, for example in the configuration of a push-button or a sliding sleeve. The push-button sits on the angled end of the leaf spring, and the offset portion of the leaf spring can thereby be lifted out of the insertion hole. The sliding sleeve of the modified exemplary embodiment lifts the spring out via an inclined-plane sliding connection when the sleeve is displaced axially against spring force.
Patent DE-3134995-A1 (DE)
Title: Process and apparatus for detecting changes in information in programmable memories
Inventor: FRITZ EBERHARD
IPC: G01R31/30
Filed: 1981-09-04
Abstract: A process which serves for detecting changes in information in programmable memories is proposed. By increasing or reducing the operating voltage of the memory element, the internally generated inquiry threshold is either raised or lowered. Thus, if the current characteristic of a memory component changes, for example due to losses in the memory element, the said characteristic shifts, with the result that at a certain point in time the changed inquiry voltage is exceeded or not reached for the first time. If the signal inquired at normal voltage is then compared with the signal which occurs with a changed inquiry voltage, it can already be detected at an early stage if a memory cell at a later point in time changes its stored information value, since different memory contents are then inquired. It is then possible to trigger a fault signal before the data are changed. <IMAGE>

Title: Device for identifying leakage and/or fault points in lines containing a flowing medium
Inventor: HERRMANN PAUL
IPC: G01H1/00
Filed: 1982-04-16
Abstract: The object of the present invention is to provide a device for determining leakage and/or fault points in lines containing a flowing medium, which is notable for simple and easy operation combined with high sensitivity. According to the invention, this is achieved in that a crystal diaphragm is attached to a short metal probe tip and is in physical contact with the probe tip, and in that the crystal diaphragm and the probe tip are accommodated in a common housing from which the probe tip projects a short distance at one end. As a result of the short probe tip, the device according to the invention picks up little ambient noise, and it is easy to operate and versatile in use because of its short structural length. The crystal diaphragm likewise offers the advantage of greater sensitivity in comparison with a dynamic microphone. The device according to the invention can be produced in convenient dimensions, with a length preferably between 10 and 20 cm, and is thus easily portable and easy to handle.
Patent DE-3225194-A1 (DE)
Title: Rotary combustion engine
Inventor: MAMIC ZDRAVKO
IPC: F02B47/00
Filed: 1982-07-06
Abstract: A rotary combustion engine primarily comprises a cylindrical housing in addition to a rotor with blades, injection nozzle and a steam feed nozzle. The supercharging is performed under pressure by way of a port in the side cover, whilst at the same time the exhaust gases are forced out through the outlet of the opposing cover. The cooling system comprises bores, which are so arranged that in the final stage dry steam is formed, which is led by way of a feed nozzle into the combustion chamber and in addition boosts the usual detonation pressure of the combustion gases. The rotor is cooled by an axial fan, which drives the cooling air through holes provided. The rotor which is arranged eccentrically in the housing or cylinder, is driven by means of the blades provided, the supercharging occurring in the interstices of the blades. The engine power is essentially increased by the steam supply. The engine has improved efficiency compared to known combustion engines, is smaller and lighter, quieter running with a lower fuel consumption.
