Filed: 1983-01-17
Abstract: The invention relates to a process for producing a cooling device on moulds for shaping plastics, especially on blow moulds, in which process channels are provided in the mould parts for the passage of the coolant. Each mould part is recessed at its reverse side in such a shape that a sufficient wall thickness from the point of view of strength still remains as far as the mould cavity, the channels for the coolant are modelled on the reverse side of the mould cavity wall using a modelling material which can be removed again, the recess on the reverse side of the mould part is then filled with a curable, mouldable filling material, the filling material is cured and the modelling material is removed from the cooling channels. In the mould, the cooling channels are arranged between the mould cavity wall and a filling body produced by curing a mouldable material and at least partly filling the recess on the reverse side of the mould part. The manufacture of the cooling device on the mould parts is simplified in particular in comparison to machining-out of the cooling channels. Furthermore the cooling of the mould is increased so that a reduction in the cooling time, and therefore an increase in production, of the mould is possible.

Title: Circuit arrangement for driving a solenoid valve, especially for fuel-injection valves
Inventor: KNUETTEL RICHARD
IPC: H01H47/32
Filed: 1983-12-09
Abstract: A solenoid valve is switched in a reciprocating manner between an open position and a closed position, by means of a transistor. A pulse-width modulated squarewave signal from a microcomputer is used as a reference signal. In order to keep the magnet current constant in the event of temperature and hence resistance changes in the magnet winding, a comparator stage is provided in which an amplitude comparison is carried out between the magnet current as the actual value and an analogue voltage which is formed from the squarewave signal and is pulsed in synchronism with the squarewave signal. The output signal of the comparator stage switches the transistor at the frequency of the duty ratio and a very high repetition frequency, as a result of which a temperature-independent mean value of the operating voltage applied to the solenoid valve is achieved. <IMAGE>

The invention relates to dedicated telecommunications connections via which digital signals are transmitted. A dedicated telecommunications connection of this type for digital signals leads from a data terminal device at the transmitting end via interface lines at the transmitting end, via a data transmission device at the transmitting end, via at least one telecommunications exchange and via a data transmission device at the receiving end to a data terminal device at the receiving end. Sensors are disposed in the data terminal devices at the transmitting end and are connected to the interface lines at the transmitting end, and the output signals of the latter are transmitted to the traffic-measuring device in the telecommunications exchange.
Patent DE-3408283-A1 (DE)
Title: Outlet station for piece goods
Inventor: SCHULTE LOTHAR
IPC: B65G47/68
Filed: 1984-03-07
Abstract: Outlet stations of this type consist of holding elements which are placed against the ends of the rows of piece goods which are to be broken up and hold them until the desired central row or other rows of the arrangement have been broken up and/or transported away. This results in the disadvantage that, because of the way in which the retaining device operates, jamming of the individual rows of piece goods in relation to one another occurs, which disadvantage is eliminated by providing at the end of the outlet station (1) and/or transport section (4) holding elements (9, 10) which engage eccentrically with the rows of piece goods (2) and which, in the stopping condition, separate the row (2) in question from the respectively adjacent row of piece goods (2) by means of a wedge-shaped arrangement, as the transport device continues to operate. <IMAGE>

Title: Process and device for producing cement clinker from cement raw meal
Inventor: HENRICH GUENTER DR
IPC: C04B7/44
Filed: 1984-05-10
Abstract: It is known that during the production of cement clinker the raw meal is precalcined in a heat exchanger system with the aid of hot furnace exhaust gases and subsequently burnt in a burning device, in particular a tubular rotary kiln, downstream of the heat exchanger system to form cement clinker. It is also known to pelletise the cement raw materials and to subject the pellets after predrying on a sinter belt to a burning process of several hours. However, this can be relatively energy- and cost-intensive. According to the invention, however, an improvement of the production of cement clinker can be achieved in that the cement raw meal is pressed to form blanks, in particular shells, and the latter are burnt in a burning process to form clinker. <IMAGE>

Title: Drive for bucket chains, in particular for bucket-chain excavators
Inventor: SCHULZ FRANK
IPC: B65G65/06
Filed: 1984-07-21
Abstract: Drive for bucket chains, in particular for bucket-chain excavators, which are used in the excavating and winning of soils. The aim is to increase the conveying capacity and efficiency of chain-and-bucket excavators without a substantial increase in the service mass. The object is to increase the bucket-chain speed and to reduce the spacing of the excavator buckets and at the same time reduce the causes of wear at the bucket chain. This is done in such a way that a disc wheel is used instead of the drive sprocket. Its drum shell, at theoretically full contact by the bucket chain, accommodates an integral quantity of excavator buckets and proportional bucket chain. There are recesses in the drum shell for the material to be conveyed. Chute plates divert the same to the outside. Toothed corners on the drum shell engage in the bucket chain for driving.

Patent DE-3430652-A1 (DE)
Title: Contact tube
Inventor: PACHE NORBERT
IPC: B23K9/12
Filed: 1984-08-21
Abstract: The present invention relates to a contact tube for inert gas-shielded arc welding, in order to guide the welding wire and transmit the current from the contact tube to the welding wire, which is effected in a known manner by a contact tube in which the guide bore is 0.2 mm larger than the wire to be welded. The welding wire, wound under an initial tension on spools, passes in a curved form through the contact tube. The direction in which the welding wire leaves the contact tube alters depending on the pretensioning of the welding wire or the wear of the contact tube. The welding contour cannot be achieved in an exact and reproducibly accurate manner. On the other hand the curvature of the wire is desired so that in the guide bore of the contact tube, which is 0.2 mm larger, the wire rests in a punctiform manner against the borehole wall and thus permits current to be transmitted. Since every 0.5 mm enlargement of the outlet opening can produce a deviation in the welding contour of around +1.0 mm, in practice contact tubes that are otherwise still operational are exchanged if the outlet opening has enlarged. The friction of the curved wire against the outlet opening is responsible for the change in the latter. In order to eliminate this defect, the invention proposes aligning the curved welding wire so that a straight welding wire is fed to the contact tube using a pressing mechanism. The positive properties of this contact tube, such as: ...   Original abstract incomplete.
