Title: Compartmentalised mat for a boot
Inventor: SCHMIDT FRIEDRICH WILHELM
IPC: B60R7/02
Filed: 1988-11-21
Abstract: The purpose of the invention of this compartmentalised mat for a boot is the securing of loose objects which are taken along in loading spaces of vehicles - for example in boots of motor vehicles. By virtue of a combination of vertical and horizontal cuts in the mat tabs are produced which can be folded upwards to form compartments of different sizes. In these compartments the objects can be secured between the bent-up tabs and in this manner can be prevented from sliding to and fro. For the purpose of providing an additional fastening the tabs are provided on that side which is to be folded upwards with eyelets. These can be connected to one another by rubber bands and due to the tensile force of said bands the tabs are pressed onto the floor.
Patent DE-3841844-A1 (DE)
Inventor: SCHOEN CHRISTIAN O
IPC: C10M175/00
Filed: 1988-12-13
Abstract: Environmentally harmful heterocompounds (harmful substances) of organic media which are or have been rendered free-flowing, as for example waste material or highly toxic material containing chlorinated hydrocarbon or sulphur, produced for example through distillation of chemical residues, dioxine and the like, and through recycling of waste material, where silting-up and incrustation occur during condensation, are separated and decomposed by a special process using a single-tube reactor. Harmful substances are thus separated below the cracking threshold and transformed into easily purifiable substances; alternatively, in certain cases, the media are heated beyond the cracking threshold, thus producing new substances, for example methane, propane and the like. The high risk of associated silting-up or incrustation, in particular during condensation, is avoided by using injection condensation, preferably fractional condensation.

Title: Meat hook for suspending sides of ham in particular and similar heavy pieces of meat
Inventor: LIESAUS ERWIN
IPC: A22C15/00
Filed: 1989-07-07
Abstract: Known meat hooks of the aforementioned type are designed in such a way that their suspension hooks point in the direction opposite to the direction of the prongs. When the load is a heavy one, the prongs change their direction until they reach the horizontal, which means that it is easily possible for suspended pieces of meat to slide off the prongs. The new meat hook is intended to make secure suspension possible. The new meat hook is characterised in that it has an arm (3) which is bent at right angles and extends from a supporting bow (2), essentially parallel to the prongs (1), upwards at an angle, the suspension bow (4) mounted on the upper end of the arm (3) being twisted laterally through 90@ with respect to the latter. The new meat hook advantageously ensures that when subjected to the load of a piece of meat, the prongs at least retain their upwardly inclined position or are even displaced further upwards. This ensures that pieces of meat can be reliably suspended without there being a danger of them falling off involuntarily. The new meat hook is suitable for all applications in the processing and dressing of meat for which conventional meat hooks have previously been used. <IMAGE>

Title: Bright annealing of steel strip coils - by adjusting inert gas flow rate to correspond to emulsion evaporation
Inventor: BUDACH MARINA DIPL ING
IPC: C21D9/52
Filed: 1989-09-19
Abstract: The carbon pick-up during the bright annealing of solid coils rolled steel strip in top hat furnaces under a protective gas atmosphere is minimised by varying, during the heating of the coldest spot to the final temperature, the admission of the inert gas as a function of the released amount of evaporated emulsion which had been applied during the rolling operation. The gas is admitted, e.g. by one sharp increase and is followed by a decrease. The inert gas flow is kept to a low level until the temperature has reached the point where the emulsion evaporates. When this occurs, the flow rate is increased in one or two steps to raise the flushing rate. When the evaporation ends, the flow rate can again be reduced. ADVANTAGE - This can reduce the carbon pick-up to one tenth. It also reduces the specific inert gas consumption and the specific heating gas consumption.
