Patent DE-3406357-A1 (DE)
Title: Acetabulum which can be anchored without cement
Inventor: GARTENMANN WALTER DR MED
IPC: A61F2/30
Filed: 1984-02-22
Abstract: The acetabulum intended for anchorage without cement has circular ribs (5) only in the middle region of the outer surface, the ribs snapping into a milled annular groove (16). A projecting edge (8) is present over an angular region ( beta ) of about 120 DEG , and this edge restricts penetration of the acetabulum body (1) in the bone (15). Finally, there is an off-centre anchorage peg (4) in a predetermined position relative to the angular region ( beta ) of the edge (8) as a safeguard against rotation. The combination of all detailed characteristics results in an acetabulum which can be anchored without cement and has a firm seat in the bone and with which loss of bony substance is low when it is used. <IMAGE>

This is achieved in that the carriage is held on the piston so as to be movable in one direction.
Patent DE-3413930-A1 (DE)
Title: Centrifugal pump
Inventor: SCHNABEL GERHARD DIPL ING
IPC: F04D13/02
Filed: 1984-04-13
Abstract: The invention relates to a centrifugal pump having an impeller which, by means of a bearing, is rotatably mounted in a casing. A known centrifugal pump of this type is constructed essentially without roller bearings and sleeve bearings, at least two slip rings being provided for hydrodynamic bearings. The casing as well as the impeller in this centrifugal pump are made of plastic, so that, on the one hand, aggressive and/or corrosive media can be pumped, but, on the other hand, considerable problems arise at temperatures greater than 370 K, because of the relatively high thermal expansion coefficient. With a limited outlay in terms of design and construction, a centrifugal pump of this type is to be improved in that media having higher temperatures should be pumpable without difficulties, while achieving a long useful life. As a solution it is proposed that the impeller (2), together with a shaft, consist of a ceramic material and that a region (20, 22) of the outer face of the impeller (2) be constructed directly as a sleeve bearing face. <IMAGE>

Title: Moulding device for moulding concrete parts
Inventor: KRAISS RICHARD
IPC: B28B21/86
Filed: 1984-04-14
Abstract: A moulding device for concrete parts is proposed the mould core of which has at least one centring ring with an inner supporting surface. By means of the centring ring, the mould core can be fixed to at least one centring part of the vibrator which centring part is provided with a coaxial outer countersurface. Between the centring ring and centring part there is disposed a pressure medium-actuated clamping device which has at least one pressure element which can be pressed against the supporting surface counter to a restoring force. This pressure element consists of an annular segment forming a part of the centring part with an inner pressure chamber which can be supplied with a pressure medium via a pressure medium line. The annular segment is formed by a circumferential section of the centring part on the vibrator, the outer wall part of which centring part forms with its outer surface a section of the outer countersurface and is elastically expanded when subjected to pressure and automatically springs back when the pressure is relieved. An extremely fast mould exchange is thus possible. The clamping device is simple, inexpensive, requires little space and few components and is not susceptible to wear.

Title: Method for controlling the spindle speed on spinning machines and spinning and drawing machines
Inventor: HOMBURG AXEL
IPC: B65H61/00
Filed: 1984-07-07
Abstract: The object on which the invention is based is to keep the fluctuations of the rotational speed and of the yarn pull as low as possible on spinning machines and spinning and drawing machines with direct drive. The aim is to achieve maximum speed fluctuations of +/- 1.0<o>/oo and especially in the region of +/- 0.1<o>/oo. This is achieved by a comparison between the desired value of the winding speed and the actual value of the circumferential speed of the bobbin and by linking the deviation signal obtained with the spindle-speed signal by means of a multiplier. In one embodiment, in addition to the comparison of the analog signals, a comparison of the digital signals is also carried out; in addition, the yarn pull can be entered as a correcting value into the control circuit.
Patent DE-3426988-A1 (DE)
Title: Drive for displacing a component which can move between two limit positions
Inventor: BERTSCH HANS ING GRAD
IPC: E05F15/689
Filed: 1984-07-21
Abstract: A drive is proposed which is used for displacing a component, for example a sliding roof which is part of a motor vehicle, which can move between two limit positions. The actuating drive comprises an electrical drive motor whose drive movement acts on a transmission which varies the speed of this movement. Furthermore, the actuating drive has a limit switch which is located in the operating circuit of the electric motor. In order to achieve particularly accurate switching off of the limit positions, the actuating drive is provided with two position sensors which are connected by means of a logic AND gate, the one position sensor picking off the movement of a transmission element which moves quickly and the other position sensor picking off the movement of a transmission element which moves slowly. The output signals of the two position sensors influence the operating circuit of the electric motor when both signals are present at the input of the AND gate. <IMAGE>

Patent DE-3526129-A1 (DE)
Title: Enamelling process and mechanical devices for applying, drying and firing base enamels and surface enamels
Inventor: MESSMER ERNST
IPC: C23D11/00
Filed: 1985-07-22
Abstract: The essential process steps of the invention are illustrated by the attached diagrammatic drawing. After the handle has been joined on (1), the parts are moved by a roll conveyor (2) to the crockery feeder (3). The small slip container (4) can be rapidly replaced by regenerated enamel slip. By means of the enamel application machine (5), even application of enamel is achieved not by a rotary movement (centrifugal effect), but by transposition of the automatically opening and closing pot holder in the opposite direction into an angular position of 90 DEG  and 80 DEG . The application machine (5) of a diameter of 500 cm has a small space requirement and, with 12 pot positions as compared with more than 200 pot positions in conventional machines, gives a small preparation time during running in and running out and also during cleaning. At the discharge point (6), the crockery is deposited onto the edge-cleaning belt (7) and then transferred to the crockery edge-drying belt. Further running of the enamel slip is avoided by the drying of the edge zone, and the crockery can therefore be directly deposited at the transfer point (9) onto the hangers of the reversing oven. The oven conveyor passes first through a drier upstream of the U-oven and then through the preheating and firing zones. <IMAGE>
