Patent DE-2923216-A1 (DE)
Title: Flow heater with protective pressure switch - shunted by non-return valve to allow disconnection when pressure in heating chamber exceeds limit
Inventor: SIMON BERNHARD
IPC: F24H9/20
Filed: 1979-06-08
Abstract: The flow heater has a protection switch that switches off the heating current when the pressure inside the heating chamber exceeds a given limit. The protection switch consists of a pressure-difference switch (11). The switch is shunted by a non-return valve (4). The switch and valve are located between the mains water supply (F) and the heating chamber (1). The valve opens when a pressure surge occurs on the mains side so that the switch does not respond to this pressure increase. An increase in pressure in the heating chamber closes the valve and allows the switch to respond.

Title: Printing sheet lateral alignment mechanism - has suction opening and grip controlled by valve operating to given cycle
Inventor: SCHWEBEL ADOLF
IPC: B65H9/10
Filed: 1979-07-20
Abstract: The lateral alignment mechanism is for a sheet on the loading table of a processing machine, partic. a printing press, having a suction grip engaging with the sheets and moving in stages in a straight line at right angles to the lateral stop and from it. A suction opening is shut by the sheet, and the amount of suction is controlled dependent on the degree of opening.

Title: Wear resistant inserts or fittings for valves etc. - made from silicon nitride or silicon carbide to increase working life of valves
Inventor: VOGEL GUENTHER ING GRAD
IPC: F16K1/42
Filed: 1980-05-13
Abstract: The inserts or fittings are used in appts. through which materials flow, e.g. valves. The regions of the inserts etc. which are exposed to wear are made of Si3N4 or SiC. The inserts are pref. valves, valve seats and/or linings made of Si3N4 or SiC. The invention is used esp. for a valve, in which the valve cone and the valve seat are made of either Si3N4 or SiC; and the inlet channel and/or the outlet channel of the valve are provided with a sleeve made of Si3N4 or SiC. In the conventional mfr. of valves etc. the components exposed to wear or abrasion are made of high tensile steels, hard metals, or oxide ceramics; but these material are unsatisfactory due to their low bending strength, low shock resistance, and/or differences in their coeffts. of thermal expansion. These problems are eliminated by using Si3N4 or SiC for valve components exposed to wear.

Title: Data communication from moving goods wagon - uses pick=up coil on vehicle to receive impulses from coil on track side and re-transmits sensor data to data processor further along track
Inventor: SCHMALL KARL-HEINZ
IPC: B61L3/00
Filed: 1980-10-30
Abstract: To obtain operating data from a moving vehicle such as a goods wagon, temperature sensors (F1,F2,F3) are mounted in the region of the axle and connected to a data measuring and transmission device (3) which also contains an energy store. The latter is connected to a coil (4) which travels parallel to a stationary energy transmitting coil (5) as well as a data transmission coil (6). The energy coil (5) is connected with an emitter (7) which gives out a high frequency magnetic field which is picked up by the coil (4) on the goods wagon as it passes by. This electrical energy supplies the data measuring and transmitting device (3) as well as the temperature sensors (F1,F2,F3), so that after a set time, signals containing data are emitted by the coil on the wagon and picked up by another coil mounted further along the track. This data can be processed and the condition of the axles interpreted i.e. whether any temperature rise due to overloading is present.

Title: Doll head two-colour printing machine - has bell-crank lever with pad on horizontally reciprocating column
Inventor: LINK THEODOR DIPL ING
IPC: B41F17/00
Filed: 1980-12-18
Abstract: The mechanism simultaneously prints flat and non-flat surfaces alongside each other in two colours, the surface being more than 1mm. apart. Their width in the direction of the gap is roughly one-fifth of the possible printing length. The system is esp. used for the heads of dolls. It has a bell-crank lever (3) in bearings on a column (2) secured by a cross-member (1), and moved between stops (5) in opposition to a return spring (7) by the vertical motions of a striker lever (4) with compensator spring (6). Horizontal movement of the column causes the bell-crank lever to move to and fro between the divided ink basin with printed block (9) and the surfaces to be printed (10). Ink is taken up from the basin and applied to these surfaces by a pad (8).

Patent DE-3104941-A1 (DE)
Inventor: HOLZNER PETER ING GRAD
IPC: G06F17/30
Filed: 1981-02-11
Abstract: A micro-computer system for data processing and for the rapid location of a characteristic block has a working store which is organized so that it can be used as a conventional working store with a data width of, for example, one byte. This working store contains a data file storage zone for storing, along with other data, a plurality of blocks of multi-byte characteristics. Several read-write stores, all of which contain one or more bytes of the block of characteristics, are read out simultaneously, while the data ports of the read-write stores are cut off from the data bus. The comparison with the combinations searched for is carried out via comparators which compare the data read from the read-write stores with the combinations searched for, which are intermediately stored. The outputs of the comparators are connected to the inputs of an AND gate which produces an identity signal which terminates the searching.

Title: Materials container
Inventor: HOELZEMANN RUEDIGER
IPC: B65D88/52
Filed: 1981-03-19
Abstract: The invention relates to a materials container which consists of a cuboid frame structure with upper and lower chords and four corner posts, into which frame structure trapezoidal plates are inserted. Materials containers of this type are intended solely to store materials and tools in a weather-proof and theft-proof manner. They therefore have to be very inexpensive, but should also be able to be assembled and demounted in a very short time to reduce labour costs. According to the invention, this is achieved by a materials container, in which the lower chords (4) are edged in an S-shape in cross-section and a channel (6) which is open at the top is thus obtained for the insertion of trapezoidal sheets (7), the upper chords (10) of the longitudinal sides having a channel (17) which is open at the bottom with approximately the same cross-section, but are continued (16) in an L-shape at the top, such that a channel (13) pointing into the container is produced for receiving the trapezoidal roof surface (14), the upper and lower chords of the end faces being combined in each case with two corner posts to form an end frame, and the longitudinal upper (10) and lower (4) chords being able to be screwed to the corner posts. <IMAGE>

Abstract: For forming a link in a chain for distributing goods which retain their quality characteristics only at refrigerator temperatures, use is made of a cooling container which can be equipped with cooling accumulators and works with a heat-operated cold absorption apparatus and which is divided into three spaces which work with different temperatures, a first of which serves for charging the cooling accumulators with the aid of the absorption refrigerating apparatus, a second of which stores the charged cooling accumulators and the third space of which receives the goods to be transported on distribution at temperatures slightly above the freezing point. With such a container, sensitive goods such as for example vaccines or delicate foods such as in particular fish can be stored and transported without damage for a number of days even in hot climate zones even without operating the refrigerating apparatus.
