Patent DE-3300030-A1 (DE)
Inventor: MATZEN MAX
IPC: F02M59/44
Filed: 1983-01-03

Patent DE-3301741-A1 (DE)
Title: Fuel pump with pre-excitation by permanent magnet and controlled piston stroke
Inventor: GAST THEODOR PROF DR ING
IPC: H01F7/16
Filed: 1983-01-20
Abstract: A fuel pump is proposed in which a piston is moved by the interaction of a permanently magnetised and an electromagnetic field. The piston travel is detected by means of a measuring sensor. The signal of the sensor controls the current through the magnet windings of the pump in such a way that the position of the piston at any instant is determined by the time curve of an external control variable. The frequency and amplitude of the piston movement can thereby be controlled independently of one another as a function of the control variable. This results in a wide range for the volume flow of the pump. Furthermore this depends only to a slight extent on the pressure differential to be overcome, so that it can be adjusted very accurately to desired values. <IMAGE>

Patent DE-3310924-A1 (DE)
Title: Method for the production of ceramic powders of high sinter activity
Inventor: HAUSNER HANS PROF DR
IPC: C01G49/00
Filed: 1983-03-25
Abstract: The invention relates to oxidic sinter-active ceramic powders of high sinter activity, which attain very high sinter densities at the lowest possible sintering temperatures. The sparingly soluble intermediate products (such as hydroxides, carbonates, oxalates and mixtures thereof) precipitated or co-precipitated from a solution which are obtained in the course of the production of the powder are freed of excess solvent by freeze drying before conversion into the corresponding oxide. In this way, agglomerates or aggregates of powder particles are avoided. The intermediates produced during the course of the process can be treated by freeze-drying.

Patent DE-3319853-A1 (DE)
Title: Milling device for the separation of sack contents which have been formed into a lump and/or agglomerated to a greater or lesser extent
IPC: B65G69/14
Filed: 1983-06-01
Abstract: The invention relates to a two-roller milling device for separation of agglomerated sack contents. In order to be able to process agglomerations of material affecting some of the material, it is in some cases necessary to segregate this agglomerated material and crush it separately. As the binding of the particles to one another frequently only gives rise to cohesion when the material is not subjected to stress, a simple procedure is conceivable. It is therefore the aim of the invention to specify a milling device which permits separation of the agglomerations in a simple fashion without interrupting the further processing of the sacks and/or the sack contents, as they pass through the system. It is provided that the rollers (2) should be separately drivable with circumferential speeds which can be set differently from one another and that the distance between the axles should be modifiable by means of adjusting elements (10), the adjusting elements (10) releasing an additional load-dependent buffer path when there is an overload. The stationary roller is arranged in the crosspiece of a U-shaped supporting frame (9) and the adjustable roller is arranged in a sliding carriage (8) guided between the U-legs. In order to permit introduction of a grating foundation, carrier elements (5/6) which also form squeezing strips parallel to the axles are arranged around the surface of each roller, distributed at equal distances. A modification envisages arrangement of circular knife blades (7) between the surfaces (4) divided into sections. <IMAGE>

Patent DE-3338487-A1 (DE)
Title: Press roll
Inventor: HUND HELMUT
IPC: B30B3/00
Filed: 1983-10-22
Abstract: The press roll (1) contains a roll shell (6) which is made of an easily deformable material, for example rubber or plastic, and which is rotatable about a fixed mount (5) and intended for cooperation with a counter roll (2). The roll shell (6) is guided with its inner surface in the region of the pressing point on the mount (5) over at least one concave support surface (12) deviating from the circular cylindrical form of the inner surface of the roll shell (6), which support surface permits a local deformation of the roll shell (6) for adaptation to a circumferential part of the counter roll (2). The ends of the roll shell (6) are connected in a sealing manner with in each case one round cover (16) mounted to be rotatable on the mount (5). This sealing connection contains an annular element (support ring 17) extending over the circumference of the cover (16), which is made, for example, of rubber-elastic material and which upon rotary movement of the roll shell (6) permits an adaptation of its edge part to the shape of the roll shell (6) deviating from the circular shape at the pressing point. This results correspondingly in a gentle guidance and sealing of the roll shell (6), which is largely relieved, in particular of forces acting in the axial direction. <IMAGE>

Title: Lightweight building-element system which conforms to more stringent thermal requirements
Inventor: LAJOS TOLNAI DR ING
IPC: E04F13/08
Filed: 1984-04-24
Abstract: The subject of the invention is a modular, lightweight building-element system which conforms to more stringent thermal requirements and is provided with joint connection fittings which can be mutually connected and released in a rapid manner. As a result of its specific design, the building-element system is suitable for erecting buildings having various dimensions and purposes, in particular weekend houses, holiday homes, temporary municipal and service installations, and dwellings. The building elements are provided with cladding ensuring an air gap, through which air can pass, and thus ensure a favourable embodiment in terms of both heat and cold. The load-bearing and/or the load-transferring connection between the individual building elements is ensured by fastening elements which are mounted at the manufacturer's works and function according to the same principle. When assembling the individual building elements to one another, the fastening elements render a special supporting or bracing action of the building elements unnecessary. According to their purpose, the individual building elements are embodied as load-bearing, solid outside-wall and inside-wall building elements, partition building elements or ceiling building elements, and/or building elements of this type which include windows or doors.

Abstract: A magnetic head comprising a stratified buildup on a non-magnetic substrate for a recording medium to be magnetized vertically comprises a ring head-like conducting body for carrying magnetic flux having two magnet legs which comprise several magnetic layers with predetermined saturation magnetization and delineate a space in between, through which the turns of an at least largely flat write/read coil winding extend. With this head it is possible to generate a sufficiently large read voltage, wherein the same advantages are present as if single-pole heads are used. The first magnet leg comprises, in the region of its pole, at least a first magnetic layer having a predetermined low saturation magnetization and the second magnet leg comprises, at least in the region of its pole, a magnetic layer, the saturation magnetization of which is larger than the saturation magnetization of the first magnetic layer of the first magnet leg, so that for the write function the pole area of the first magnetic layer is saturated magnetically due to a write current flowing in the coil winding. Preferably, the first magnet leg has, outside its pole area, at least one further magnetic layer comprising a material with a higher saturation magnetization.

Patent DE-3425419-A1 (DE)
Inventor: KAUBEK FRITZ DIPL ING
IPC: F25D5/02
Filed: 1984-07-10
Abstract: The invention describes portable cooling and heating devices and their process of operation in accordance with the adsorption principle utilizing the adsorption substance pair of zeolite-water. The devices operate without substance and heat exchange from the environment, in that the evaporation heat originates from the solidifying heat of a non-evaporating amount of water and that the released adsorption heat is stored in the form of tangible heat of the zeolite filler. The ice which had been generated during the adsorption process is suitable for human consumption.
