Title: Bus system circuitry connecting digital send and receive units - passes data from sending units FOR ONE RECEIVER AT ANY TIME
Inventor: STAUDTE HANS-GEORG DIPL ING
IPC: G08C15/12
Filed: 1975-02-20
Abstract: The circuitry is such that only one BUS system is required to connect digital input units e.g. counters with a number of data receiving units e.g. printers so as to transfer large quantities of data. The circuit arrangement has the data senders (1, 2) connected through outlet gates (3, 4) to the BUS, the gates being under program control (10). The receiving units e.g. a number display (5), an output channel to a printer (6) and a receiver connected to a timing control unit (9) through a gate (8), are also interconnected with the BUS. This gate (8) can also be opened and closed under program control. Output times from the sending units are less than one second, so that switching from one sender to the other is not noticeable.

Title: Pressing dry material such as fertiliser into granulate - adding sulphur and an oxidant to generate heat which aids compaction
Inventor: AUTENRIETH HANS DR ING
IPC: C05G3/00
Filed: 1975-06-09
Abstract: Process for compacting dry, fine-grained, bulk materials to mfr. granulates in pressing plant operating at high pressures. The novelty is that prior to pressing, powdered or liq. substances or mixts. of substances are added to the bulk material and, during pressing, the substances decompose or react with each other to generate heat. The substances pref. consist of sulphur with the subsequent addn. and mixing of an oxidant, e.g. nitrates or nitrites and/or chlorates, perchlorates, or a 30% soln. of H2O2; and 200-2000g of the substances are pref. used per tonne of the bulk material to provide the desired exothermic reaction. Process is useful e.g. for the compaction of fine salts such as fertiliser salts. The success of the compacting process depends on the heat generated by friction between the particles of the bulk material in the zone of highest pressure, obtd. e.g. in compaction by rolls. The invention provides additional heat by an exothermic reaction, e.g. oxidn., which produces SO3 which liquifies and does not create pressure which would disturb the compacting operation.

Title: Crucibleless zone melting device for single crystals - with bottleneck supporting funnel permanently filled with granular material
Inventor: KELLER WOLFGANG DR
IPC: C30B13/28
Filed: 1975-07-04
Abstract: In the parent patent, the rod end holding the seed crystal in a crucible-free zone melting process is supported by a rotatable funnel. This funnel is axially movable and is filled with quartz sand or a solidified metal after it has been raised to its top position. In this addn. the funnel can be filled with the stabilisation medium before it is raised if this consists of a granular or spherical material such as spheres of metal, glass or quartz of 3mm dia. or of dust free coarse silicon of 2-5 mm particle size. This saves the filling device and the dust development during filling. The stabilisation medium need only be cleaned out from time to time. Thick (over 70 mm) and long (over 500 mm) single crystals can be pulled with this device.

Title: Injection nozzle for injection mouding machines - having outwardly-directed opening in chamber contg spring-loaded closure needle
Inventor: HERZOG KURT
IPC: B29C45/23
Filed: 1975-12-04
Abstract: Injection nozzle for injection moulding machines for processing thermoplastic resins has a spring-loaded closure needle that opens automatically under the action of molten resin at the injection pressure, and an outwardly-directed opening in the region of the chamber contg. the needle, in front of the closure needle spring. Molten material leaking along the front part of the closure needle, under the action of very high injection pressures, is passed outwards through the opening. The injection pressure acts behind this opening, and introduction of leaking material into the spring chamber is avoided.

Title: Guidance rollers for self loading container lorry - with angled axes and tapered profiles for location as lorry is backed onto container
Inventor: KNETSCH GERHARD
IPC: B60P1/64
Filed: 1975-12-23
Abstract: The self loading container lorry has a loading frame (8) pivotted about a front horizontal axis, and supported at the rear end on height adjusting dampers.

Title: Stamping machine for ingots and billets - has stamping wheel whose adjusting unit is separate from stamping unit and is unaffected by impact forces
Inventor: NORMAN EDWARD IAN
IPC: B44B5/00
Filed: 1976-06-26
Abstract: A stamping machine for ingots, billets and similar workpieces has a stamping head with adjustable and lockable stamping wheels, a stamping wheel adjusting unit (3) and a displacement unit for moving the stamping arm into and out of the path of motion of the ingot. The stamping wheel adjusting unit (3) is fixed and separate from the stamping head. A coupling system with setting wheels (31-38) corresponding to the number of symbols which are to be stampled connects the stamping head to the adjusting unit when the stamping head has been moved by the adjusting unit out of the ingots path of motion into a coupling postion. In the coupling position the locking action of the stamping wheels is released and the coupling unit can be advanced corresponding to the desired adjustment of the stamping wheels. The design ensures that the impact forces arising during the stamping operation do not have a damaging affect on the adjusting unit.
