Patent DE-3213226-A1 (DE)
Title: Semiconductor component
Inventor: DEUFEL REINHARD DIPL PHYS
IPC: H01L33/00
Filed: 1982-04-08
Abstract: The invention relates to a semiconductor component, for example a III-V photodiode, having at least one p-n junction which is to be situated geometrically at a certain distance from the heterojunction. This is achieved by a lightly n-doped interlayer which displaces the hetero junction to a certain distance away from the p-doped layer. Said interlayer usually has the composition of the p-doped layer.

Title: Apparatus for rolling a wrapping leaf onto cigar, cigarillo or cheroot roll
Inventor: SCHROEDER WILHELM
IPC: A24C1/26
Filed: 1982-04-23
Abstract: An apparatus for rolling a wrapping leaf onto a cigar, cigarillo or cheroot roll. A conveyor belt (4) is arranged between a blank punching device (1) and a rolling machine (5). The blank punching device (1) is provided with a fully rotating rolling apparatus (2) and a suction arm (3), the suction arm (3) laying the punched-out wrapping leaves on the conveyor belt (4). The rolling machine (5) is provided with a removal device (6), whose most important component is a suction arm (7) which takes each wrapping leaf from the conveyor belt (4) and conveys it to a gumming station and the rolling apparatus (8). The working stroke of the rolling machine (5) is shorter than the working stroke of the blank punching device (1). The drive motor of the conveyor belt (4) is controlled so that the movement of the conveyor belt (4) is prevented during the laying of a wrapping leaf on the conveyor belt (4) by the suction arm (3). As a result of the combination described above, substantial utilisation of the high performance of the rolling machine (5) is achieved with direct processing of the wrapping leaves punched out by the blank punching device (1). <IMAGE>

Title: Device for producing a collar on pipes internally coated with plastics
Inventor: MATTHIAE SIEGFRIED
IPC: B29C63/34
Filed: 1982-06-03
Abstract: The invention may be used both by a manufacturer of pipes internally coated with plastics and by the user and under construction-site conditions. The aim is to increase the lifetime of pipes internally coated with plastics. The object of the invention is to make available a corresponding device which can be used for pipes internally coated with plastic having clear diameters less than 35 mm and/or layer thicknesses less than 1 mm. A cylindrical contraction element having a somewhat larger diameter than the internal diameter of the pipe internally coated with plastic and having a non-continuous axial bore hole is rigidly connected to a moulding head. A force transmission element is guided so as to be axially movable in the bore hole and in an associated bore hole in the moulding head. The contraction element is axially extended by means of the force transmission element with a reduction in its diameter; the device is attached to the pipe end and relaxed again. Coating material is pressed into the mould of the moulding head with defined heating of the pipe end. The device is removed again after cooling.
Patent DE-3223680-A1 (DE)
Title: Fuel injection pump for internal-combustion engines
Inventor: HAEFELE WALTER
IPC: F02M59/02
Filed: 1982-06-25
Abstract: To prevent erosion on the pump housing (10) caused by the jet of fuel leaving the back-flow openings (23) at the end of injection, the fuel injection pump (Fig. 1) is provided with a baffle device (30) in the cylinder liner (12). Said device comprises at least one pin (31) in the form of a hardened bearing needle, which runs diametrically through the through-flow opening (23) and is held in such a way that it can rotate freely but is secured against axial displacement in an axially parallel receiving bore (32) of the cylinder liner (12). The pin (31) can be exchanged if it becomes worn. It is simple and cheap. Under the influence of the back-flowing fuel jet, the free rotational movability causes a rotation of the pin (31), thereby achieving high stability under load.

Abstract: A device (5) has a vessel (17) which is rotatable about a suitable axis (15) and has an end opening (21) and a removal opening (23) which is arranged at a peripheral point and can be closed with a closure element (25). Tablets to be coated are transported into the vicinity of the vessel (17) by way of a cart (89) having a container (93). The cart (89) is then raised by a lifter and tipped. The tablets can now be conducted from the container (93) into the vessel (17) via a suitable inlet trough. When the tablets (101) present in the vessel (17) have been provided with a coating, the vessel (17) is stopped in a rotated position in which its removal opening is lowermost, and a cart (89) with a container (93) to receive the tablets is moved under the removal opening (23). This opening is then opened, so that the tablets slide and fall out of the vessel into the cart (89). In this manner, the tablets can be easily and rapidly introduced into the vessel (17) and removed from it again. <IMAGE>

Patent DE-3328784-A1 (DE)
Title: Low-voltage or medium-voltage switching and distribution system which is protected against contamination by dust and adverse influences from high air humidity, and a method for achieving the desired protection
Inventor: KRAEMER WILHELM
IPC: H02B1/28
Filed: 1983-08-10
Abstract: For a low-voltage or medium-voltage switching and distribution system, which is to be protected against contamination by dust and adverse influences from high air humidity and is composed of a plurality or a multiplicity of switch panels (11...18) which are joined together, it is proposed to allocate an air-conditioning unit (20) to the switch panels or to a limited number of switch panels of the system, which unit is intended to suck in atmospheric air and to filter and to dry it; in this case, an air flow which emerges from the air-conditioning unit is intended to be supplied via a channel or pipe system (21, 22, 24), which is closed to the exterior, to each individual switch panel, causing a slight excess pressure therein in comparison with the air pressure of the external atmosphere, continuously or at intervals. The method which is used in this case is characterised in that atmospheric air is sucked in, filtered for dust and dried, or is not dried and then filtered for dust until after it has been sucked in, by means of the air-conditioning unit (20) which is to be allocated to the system, and said air is thereafter supplied via the said channel or pipe system (21, 22, 24), which is closed to the exterior, to the individual switch panels (11...18). An improvement in the method of operation of these measures can be achieved in that at least a part of the airflow supplied to the switch panels is supplied to the air-conditioning unit again. <IMAGE>

Title: Side wall for rotating vessels, in particular drum mills
Inventor: SEYLBERG HANS-PETER VAN DER
IPC: B02C17/18
Filed: 1983-09-03
Abstract: The invention relates to a side wall for rotating vessels, in particular drum mills. The aim of the invention is to provide optimum preconditions for lightweight vessel construction, the object being to achieve a moment-free introduction of supporting forces into the vessel walls. A feature of the invention is that there is connected to a dished end known per se, with a bearing bush on the inside, a spherical cap having a direction of curvature which is opposite that of the dished end, the wall thickness of the spherical cap corresponding approximately to that of the dished end and the radius of curvature corresponding approximately to half and the diameter corresponding approximately to one third of the diameter of the dished end. The spherical cap has in the centre a centring ring reaching telescopically into the bearing bush and, after compensating for production tolerances by means of the ring, can be connected using the latter rigidly to the bearing bush.
