Patent DE-3321327-A1 (DE)
Title: Toothed wheel with teeth induction-hardened by compressed air
Inventor: HOZAR KAREL DIPL ING
IPC: C21D9/32
Filed: 1983-06-13
Abstract: The invention relates to toothed wheels of chromium-nickel-molybdenum steel which, apart from iron, comprises 0.32 to 0.40% carbon, 1.3 to 1.7% chromium, 1.3 to 1.7% nickel, 0.5 to 0.8% manganese, 0.2 to 0.3% molybdenum, 0.15 to 0.40% silicon and up to 0.03% sulphur and up to 0.03% phosphorus, said toothed wheels having a module from 8 to 25 mm, and teeth which, following a gradual medium frequency gap heating process, are hardened by compressed air. As a result of the solution according to the invention, the dimensions of the hardened layer of the teeth are determined as a function of the shape and the module of the teeth, while the required mechanical values of the layer thus dimensioned are at the same time determined as a function of the effective loading of the hardened layer of the teeth by external forces. The toothed wheels are characterised in that the depth of the hardened layer of the teeth is from 0.2 to 0.44 times the module, or, at most, is equal to half the width of the tooth tip, and in that from the tooth surface to the tooth core at the same depth of the hardened layer the value of the effective hardness is greater than, or at least equal to, the value of the minimum required hardness derived from the effective tooth loading.

Title: Device for packaging cooked farinaceous products as fresh products
Inventor: TOEPFER HANS-JOACHIM
IPC: B65D81/20
Filed: 1983-06-27
Abstract: The invention relates to a method for packaging cooked farinaceous products such as Eierspätzle (German egg noodles) as fresh products. The fully cooked farinaceous items are inserted into the packagings, such as foil bags, in the presence of an inert gas, and the packagings are then heat-sealed. A pressure of the inert gas which is slightly in excess of atmospheric pressure, by 0.1 bar for example, is used especially in packaging units with larger filling weights, for example farinaceous products measured in kilograms. The filled packaging units have a cushion-like appearance and the farinaceous items do not show any tendency to form lumps or to stick together.

Patent DE-3404429-A1 (DE)
Title: Outrigger boat with inclined rig
Inventor: PLICA PETER DR
IPC: B63B35/79
Filed: 1984-02-08
Abstract: In outrigger boats with a hull of identical shape at the bow and stern, an outrigger on the lee side, and a rig inclined to windward, the mast foot of which is disposed on the outrigger end on the lee side, the heeling moment from wind forces is known to be partly or completely neutralized. In addition, a vertical sail force component results which reduces the submerged volume of the boat. The construction and handling of the boat are simplified and improved by a rig which can be displaced parallel to the longitudinal axis of the hull at the level of the mast foot, has no stays, can be rotated and tilted at the foot point and is guided by the yachtsman using a steering device, preferably a steering frame, from a platform located on the hull. Centreboards and rudders are thereby completely dispensed with, the reefing of the sail is largely avoided by inclining the rig, and in an emergency a horizontal position of the rig is possible. The platform projecting to windward serves the yachtsman as a base and provides favourable weight distribution.

Title: Clutch disc, in particular for a single-disc friction clutch of motor vehicles
Inventor: GORA HANS-JOACHIM DIPL ING
IPC: F16F15/123
Filed: 1984-07-12
Abstract: A clutch disc, in particular for a single-disc friction clutch of motor vehicles, has a spring disc carrying clutch linings, a hub connected to the latter in the direction of torque by springs and having a hub flange, and the friction disc arranged between the spring disc and the hub flange, the hub flange and the spring disc being pressed against one another axially by a prestressing spring in order - by means of the friction disc - to produce a frictional resistance which comes into operation when the spring disc is rotated relative to the hub. Arranged between the spring disc and the hub flange are spacer elements which each interact in the direction of rotation with an oblique surface such that, when the spring disc is rotated relative to the hub flange, a change in the spacing between the spring disc and the hub flange occurs when the said spring disc is rotated relative to the hub flange, altering the frictional resistance between these two parts, the change being dependent on the size of the respective angle of rotation. By means of such a configuration of the clutch disc, it is possible to eliminate in an effective manner unwanted transmission noises which would occur not only when the throttle is opened fully but also during constant travel on the road.

Patent DE-3440808-A1 (DE)
Title: Catalyst for NOx production, preferably downstream of fossil-fuel power stations
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/86
Filed: 1984-11-08
Abstract: It has already been proposed to use washing and/or flotation refuse from the underground zone of coal mining and/or ore mining to produce catalysts. By adding an additive, for example ammonia, it is possible to use a catalyst of this type to convert NOx from exhaust gases into environmentally friendly substances such as elemental nitrogen and water. Since difficulties in relation to the environment arise as a result of adding ammonia as an additive, the invention proposes that carbon materials such as coal, sawdust, peat etc. are additionally added to catalyst support materials, preferably composed of washing and flotation refuse from underground mining or similar incidentally encountered support materials and ceramisation is carried out only to an extent sufficient for a large part of the carbon materials in the catalyst material to remain behind as carbonisation product.

Patent DE-3519996-A1 (DE)
Title: Synchronisation method
Inventor: HERHOLDT ANDRIES
IPC: H04B1/713
Filed: 1985-06-04
Abstract: In the tactical use of, in particular mobile, transceiver stations, the transmission path must be secured not only against interception of the transmitted information but also against intelligent sources of noise. So-called frequency-hopping operation is suitable for this purpose. For successful signal transmission, the performance of a frequency-hopping operation requires accurate synchronisation of the stations seeking interconnection. Transmission of the synchronisation information from the calling to the called station on a fixed frequency would allow the source of noise to interfere with the connection set-up and possibly render it impossible. To prevent this, the transmission of the synchronisation information must also be performed in frequency-hopping operation. In order to perform fast synchronisation at relatively low technical cost, it is proposed to transfer the synchronisation information from the calling station (S/E1) to the called station (S/E2 or E2) with a fast frequency- hopping operation using a repetitive hop-frequency sequence whose hop frequencies, taking into account the maximum time difference between the basic clock generators (RTC) in both stations, are exclusively possible simultaneous hop frequencies of the slow frequency-hopping operation performed in the called station. <IMAGE>
