Patent DE-3135088-A1 (DE)
Title: Extension arm, especially for handling devices
Inventor: DUELLEN GERARD PROF DR ING
IPC: B25J9/06
Filed: 1981-09-01
Abstract: An extension arm (2) for a handling device consists of more than three links (3-7) articulatedly connected to one another to form a link chain. The links can perform pivoting movements relative to one another in order to move the extension arm from an extended to a more or less arcuate form. To change the form of the extension arm (2) a single drive element (25) is used, by means of which a movement is imparted from a base body (1) to the extension arm (2). The movement imparted to the first link (3) of the link chain is transmitted to the remaining links by means of actuating elements (8-11), the actuating elements being arranged such that they couple the base body (1) and the individual links (3-7) to the next member but one respectively. <IMAGE>

Title: Raw fibre cleaning - has fibre feed rate determined by supply needs at carding to reduce cleaning down times
Inventor: HERGETH HERBERT
IPC: D01G15/40
Filed: 1981-12-29
Abstract: The volume of fibre material fed from the bale opening stage to the first cleaning stage, or groups of cleaning stages, is determined by the requirements at the carding machines taking the cleaned fibres for processing. The units between the cleaning machine and the fibre processing machines operate at a preset constant speed. The system prevents down time at the cleaning stages and cuts down on peaks of intensive cleaning activity so that, as smaller amounts of fibres are cleaned, there is an improved dust removal action.

Patent DE-3208517-A1 (DE)
Title: Isolating switch or load-isolating switch with a supporting insulator which is supported such that it can pivot and with a flexible conductor
Inventor: SINNECKER GUENTHER ING GRAD
IPC: H01H33/42
Filed: 1982-03-05
Abstract: An isolating or load-isolating switch (1) has a contact arrangement (12, 21) which is fitted to a supporting insulator (13) that is supported such that it can pivot, and which is connected by means of a flexible strip (11) to a fixed-position terminal device (10). A resilient supporting element, in the form of a leaf spring (31) is fitted to the supporting insulator (13) which can pivot, which supporting element acts during switching on and prevents the flexible strip (11) springing through in the direction of the earthed components (frame 2). The flexible strip (11) is dimensioned such that it approximately assumes its extended position in the switched-on state and thus has virtually the minimum possible length. A block (32 and 33 respectively) is fitted in each case to the fixed-position supporting insulator (7) and to the supporting insulator (13) which can pivot, which block limits the bending radius of the flexible strip (11) close to its attachment points. In the switched-off state, the leaf spring (31) rests against the flexible strip (11) only at its attachment point, so that no supporting effect occurs until during the switching-on process. <IMAGE>

Title: Method for transmitting orders in gastronomic businesses
Inventor: PEJAS WOLFRAM DR
IPC: G06Q10/00
Filed: 1982-04-22
Abstract: In gastronomic businesses, a long time frequently passes between the ordering from the waiter until the order has been delivered in the kitchen and the ordered drinks or foods are delivered. This time is to be considerably shortened by the invention in that the waiter, when he takes the order at the table, outputs coded signals with a small handset to a central computer system which immediately prints out the order at the buffet and/or in the kitchen in plain text. Several waiters and waiters in different rooms can output orders simultaneously or overlapping in time to the central computer system. The orders received there are also continuously logged and printed out in plain text. The central computer system also contains another printer which prints out the bill on request on the basis of the orders stored in special areas of a memory allocated to the individual tables. <IMAGE>
Patent DE-3216304-A1 (DE)
Title: Circuit arrangement with a measuring bridge
Inventor: SCHULZ WINFRIED DR ING
IPC: G01R17/10
Filed: 1982-04-23
Abstract: The invention relates to a circuit arrangement with a measuring bridge, comprising an alternating-voltage generator, with an amplifier, with a phase-sensitive rectifier and with a low-pass filter. To make such a circuit arrangement insensitive to temperature-related changes in the phase relationship between the single at the output of the amplifier and the voltage at the control input of the phase-sensitive rectifier, using comparatively little circuit outlay, the alternating-voltage generator (1) is connected via a one-way rectifier (4) to the input diagonal (5, 6) of the measuring bridge (7), and the control input (22) of the phase-sensitive rectifier (17) is connected to the alternating-voltage generator (1) via a squarewave pulse generator (20) which is formed by a transistor (23) controlled by the alternating-voltage generator (1). The circuit arrangement is mainly suitable for measuring bridges with strain gauge converters. <IMAGE>
Patent DE-3218148-A1 (DE)
Title: Method and device for indicating the state of charging and for controlling the charging-up of a drive accumulator
Inventor: BOTHE FRANK-W DR RER NAT
IPC: B60L11/18
Filed: 1982-05-14
Abstract: In a drive accumulator (1), the charging-up should be greater by a certain factor than the preceding discharge. An indication of the state of discharge and the control of the charging-up can be carried out simply and with great accuracy if the discharge current of the accumulator is added together and thus a discharge sum is formed, if the charging current flowing into the accumulator in charging mode is added together and if the charging is switched off after the charging current sum has reached a value which is higher by a predetermined factor than the discharge sum determined. <IMAGE>

Title: Alarm system for protecting a passage
Inventor: HEILAND BERND DR ING DR
IPC: G08B13/00
Filed: 1982-07-26
Abstract: For protecting a passage (21) in a building, particularly a door or a window, the alarm system has three detectors (25, 27, 29) protecting the passage, the first detector of which is arranged in front of the second detector (27) in the direction of passing (23) to be protected and the third detector (29) is arranged behind the second detector (27) in the direction of passing (23) to be protected. The first detector (25) triggers, via a first alarm device, an alarm which is only perceptible within the house or switches on the external lighting of the house as a deterrent. A monitoring circuit triggers, via a second alarm device with an alarm signalling effect which is different from the first alarm device, a main alarm fetching assistance when first the first detector (25) and then the second detector (27) has been triggered. Alternatively, the main alarm is also triggered independently of the state of triggering of the first detector. To prevent the triggering of the main alarm after triggering of the first detector (25) and subsequent unintentional triggering of the second detector (27), the third detector (29) blocks the alarm device of the main alarm if the third detector (29) has been triggered before the second detector (27) in time. Instead of the third detector, a transmitter responding to an authorisation information, for example a key switch or a transmitter wirelessly transmitting the authorisation information, can be provided. <IMAGE>

Patent DE-3238767-A1 (DE)
Inventor: KOCH FRIEDRICH OTTO DIPL ING
IPC: B23K13/02
Filed: 1982-10-20
Abstract: It is necessary to determine the effects of welding pressure in order to control the high-frequency welding process in the manufacture of pipes with longitudinal seams. It has been discovered that measurements of the height of the welding bead provide an approximation that is satisfactory for determining the mass of the bead, which is proportional to welding pressure in known pipe geometry. The height of the bead is transmitted by an optical system to the diode matrix of a commercially available diode-matrix camera. The results are processed to control welding pressure.

Title: Front stacker
Inventor: RIESCHEL HANS ING GRAD
IPC: B66F9/18
Filed: 1983-01-03
Abstract: Front stacker serving to transport lighter, large-volume containers, in particular the known containers in seaports and inland, and to pile them up one on top of the other in the empty state with the advantage over other appliances that all technical details in the front stacker which are not required to fulfil the task referred to are dispensed with, which results in little technical complication, but on the other hand a number of technical aspects geared to the specific purpose are realised on the front stacker; e.g. it is designed with a special travelling and lifting mechanism, with a wide front axle and a drive for each wheel of the rigid axle, as a result of which very tight curves can be negotiated in combination with a rear steering wheel, and also with a non-telescopic lifting mast braced to the rear along which the load-lifting means slides vertically.

Patent DE-3306256-A1 (DE)
Title: Heat engine with concentrically rotating pistons
Inventor: RATH WALTER
IPC: F02B53/06
Filed: 1983-02-23
Abstract: The conversion of heat into mechanical energy is in most instances performed by way of reciprocating pistons, the reciprocating movement of which must be converted into a rotational movement. Innovations which convert heat energy directly into a rotary movement, whether by way of turbines or rotary engines, have been used only for special applications. The present invention is intended to overcome the disadvantages of both the reciprocating piston engines and of the known heat engines (turbines, rotary engines), the aim being to convert heat directly into rotational energy, in that there are only concentrically rotating parts, which during a full revolution are not subjected to any acceleration or deceleration due to the type of mechanical construction. The heat engine described in the present specification has pistons rotating in an annular cylinder, which is separated by one or more rotating valve circular discs so that the processes known from the principle of heat engines, such as induction, compression, expansion and exhaust can be achieved and that the piston(s) rotating in the annular cylinder can pass through the said valve disc(s). As a piston approaches a valve disc the passage is freed by a recess in the disc corresponding to the piston.

Title: Process and apparatus for continuously mixing loose solids particles with at least one liquid
Inventor: LEHMEIER HEINZ
IPC: B01F3/12
Filed: 1983-04-13
Abstract: In a process for continuously mixing loose solids particles with a liquid for applying glue to lignocellulose- and/or cellulose-containing chips, fibres and the like, the solids particles are introduced from a charging region horizontally and centrally into an inlet region, widening in the shape of a funnel, of a horizontal vessel. In this inlet region, the solids particles are set into rotary motion with simultaneous addition of liquid and then transferred into a cylindrical mixing region of the vessel, through which they migrate in the form of an annular layer of mixing material and which they leave at its outlet end. In order to allow uniform glue application which proceeds without impact action and protects the chips, while ensuring high throughput rates, the stream of solids particles fed to the inlet region horizontally and centrally is accelerated by wall friction effects in the manner of a centrifuge in such a way that an at least partially closed annular layer is formed whose speed of rotation, at the latest at the transition point to the cylindrical mixing region, is equal to the speed of rotation of mixing tools becoming active at that point.
