Patent DE-2849775-A1 (DE)
Title: Tunnel or mine gallery driving machine head control - involves thrust regulation dependent on pressure distribution of active or passive control cylinders
Inventor: ROSTOWSKI TEJA
IPC: E21D9/087
Filed: 1978-11-16
Abstract: The cutting head is used for tunneling. It is pressed forward and swivelled on all sides by hydraulic control cylinders effective in different swivel planes. The cutting head advance thrust is regulated in accordance with pressure distribution on the part of the actively introduced and/or passively effective control pressures of the cylinders. Their pressure compartments can be linked to an evaluator regulating the forwarding mechanism force according to pressure distribution. This reliably prevents excessive stressing of cutting head tools under all conditions, while maintaining max. speed of progress, with min. control effort.

Title: Filter disc from wire mesh - being punched out and compressed to give reinforced edge
Inventor: CORNELSEN JUERGEN
IPC: B01D39/10
Filed: 1979-06-16
Abstract: Filter disc is formed from layers of wire mesh laid over each other. These can have the same or different filter fineness. The disc as punched out is drawn down to give a plate type structure. The edges of this are then compressed to form an impervious reinforcing rim.

Patent DE-3005739-A1 (DE)
Inventor: SIMON JOACHIM DIPL PHYS
IPC: H04Q11/04
Filed: 1980-02-15
Abstract: Process and circuit for carrying out said process for control of the transmission of PCM signals between subscriber stations of a PCM time-division multiplex communication network in a conference service by means of a central conference control circuit in which a central processing unit allots to each station involved in a connection a transmitting pulse with cyclically repeated transmission time slots occurring in sequential pulse brackets of time frames and a receiving pulse with cyclically repeated receiving time slots occurring in sequential pulse brackets. The PCM signals are algebraically summed immediately upon their receipt and temporarily stored in a manner specific to the receiving station only until the expiration of the next succeeding period of signals not relevant to the conference, at such time when they will be transmitted to their respective conference related stations and subjected to a partial summation. The invention avoids a long delay between the respective receiving and transmitting processes and further simplifies the control of the signal processing and the central conference control circuit.

Title: Rotary direction monitor for dry centrifuges etc. - has permanent magnet(s) on rotary carrier facing two Hall elements, each in logic signal generator
Inventor: ANDERSSON HANS
IPC: G01P13/04
Filed: 1980-05-28
Abstract: The monitor has at least one permanent magnet (12) on the monitored element, or on a support coupled to the same. Next to the circular path of the magnet(s) are mounted two Hall-effect elements (106, 116) with short mutual spacing, each contained in a separate logic signal generator (10, 11). During each revolution of the permanent magnet(s), the generators transmit each a logic signal to an input (C, D) of a logic detector (16). The transmitted signals are time offset and partly overlapping. The detector transmits a logic control signal to a monitoring circuit (17-19), the signal depending on the signal train sequence from logic signal generators. Preferably the detector is formed by a D flip-flop, whose clock pulse signal input (c) is coupled to an output (10c) of the respective signal generator (10). The other generator (11) output (11c) is connected to the detector input (D).
Patent DE-3023161-A1 (DE)
Inventor: HEINZLE AUGUST
IPC: D05C11/16
Filed: 1980-06-20
Abstract: In shuttle embroidering machines, as a rule each needle carrier (1) is assigned a shuttle race (4) for receiving a shuttle (5). In the production of a multi-colour embroidery, only individual needles (2) are in use at any given time, and the under-threads which come from the shuttles (4) which have just become unnecessary, and which are still connected to the cloth web (6) to be embroidered, impede the embroidering operation. As a result of the displaceable arrangement of the shuttle guide (3), a specific needle (2) can be assigned a desired shuttle race (4) and therefore a corresponding shuttle (5), so that, in the embroidering operation, the same shuttles (5) are always in use even after a colour change or repeat change. <IMAGE>

Title: Insert for foundry moulds - esp. feeder head or thermally insulating hot top for metal moulds used for casting steel ingots
Inventor: RITTERBACH WILLY
IPC: B22C1/02
Filed: 1980-10-16
Abstract: The insert or sleeve consists of a mixt. of sand; cellulose; at least one organic binder; and at least one expanding material (I) which does not sinter. Material (I) pref. constitutes by wt. 1-10% of the mixt. used to make the insert or sleeve.
