Filed: 1983-08-09
Abstract: The invention relates to a print monitoring device for a matrix printer which has at least one column of dot punches and which successively prints the columns of the matrix on the basis of a relative displacement of the punches with respect to the recording medium. According to the invention, the characters to be printed are represented by dots in the matrix grid in such a way that, within the respective grid, each punch, (1, 2,... 7) required to print a character is actuated at least once in one column alone, the monitoring of printing taking place during this activation phase.

Title: Process and apparatus for the production of boxless casting moulds consisting of two mould halves
Inventor: HORRER ERWIN DR
IPC: B22C15/28
Filed: 1983-11-04
Abstract: In order to be able to produce a boxless casting mould consisting of two mould halves using only one injection box, the one mould half is produced in a first mould box by means of a first model, and after the removal of this model is pushed into a second mould box, which is turned through 180 DEG . The other mould half is thereafter produced in the first mould box by means of a second model. After removal of the second model, the first mould box is set on the second mould box, and the first mould box is drawn upwards from the other mould half. The one mould half, on which the other mould half is seated, is then pushed out of the second mould box by means of a lifting plunger.

Title: Handcart for transporting small loads over steps
Inventor: KNAUER DIETER
IPC: B62B5/02
Filed: 1983-11-12
Abstract: The invention relates to the improvement of a handcart with which small loads can be transported over steps. This improvement is achieved essentially in that the load-carrying element is constructed so as to taper (see Figure 1) from the rear end to the front end in a plan view. At the same time, the load-carrying element is to be of particularly acutely angled construction. The particular advantages lie in improved manoeuvrability, greater ease of handling and the fact that even winding stairs and spiral staircases can be travelled over with this improved handcart. <IMAGE>

Title: Process for the operation of a motor vehicle engine and engine arrangement for carrying out the process
IPC: F02B33/06
Filed: 1983-12-02
Abstract: The invention relates to a process for the operation of and an arrangement for a four-stroke spark ignition engine for motor vehicles, at least some of the cylinders being switched over to working as air compressors during braking and idling of the engine, in order to temporarily accumulate the air precompressed by them in a vessel, from which it is fed back into the cylinders during acceleration of the vehicle in order to increase the engine power. At the same time the arrangement can be utilised for two-stage running of the engine in the case of constant cruising at higher engine speeds, in that in at least one cylinder air is compressed by means of which the other cylinders operated as engine cylinders can then be simultaneously supercharged.

Title: Method of preventing diffusion welding on metallic bodies
Inventor: ENGEL RUDOLF
IPC: B23K20/18
Filed: 1983-12-03
Abstract: The invention relates to a method of preventing diffusion welding at the contact surfaces of two metallic bodies which are situated in a high-temperature helium atmosphere and are under high compressive load. Since protective oxide layers are not able to form in a helium atmosphere, there is a danger that, under certain conditions, the two bodies will weld together inseparably. To prevent this, it is proposed to place a refractory metal foil between the two metallic bodies as an intermediate link. Tungsten, which can be used up to 950 DEG C, appears to be the most suitable. Tantalum and niobium can be used at temperatures up to 850 DEG C. Preferably, the method according to the invention is used in experimental apparatuses for testing the behaviour of metallic materials in a helium atmosphere.

Title: Prevention against grass ingrowth in all types of tree and shrub
Inventor: GLUECK HEINRICH
IPC: A01G13/02
Filed: 1985-02-07
Abstract: Disc for conifers for preventing grass ingrowth. Tree plantations (e.g. Christmas trees) require continuous care in order to prevent grass ingrowth. This is associated with running costs and often with environmentally harmful spray agents for restricting the grass ingrowth. The disc according to the invention prevents this. The same consists of plastic, has a diameter of approximately 300 to 600 mm depending on tree size and is pushed over the trunk and nailed securely to the ground. In the region of the disc, no further grass ingrowth is thus possible. The disc saves a lot of work and environmentally harmful spray agents.
