Title: Spindle motors - are open in longitudinal channel of the spindle rail to give access and reduce material as housings are eliminated
Inventor: STAHLECKER HANS
IPC: D01H1/244
Filed: 1989-12-23
Abstract: The separate electro-motors for the individual spindles of a spinning or twisting machine have their stators (26) and rotors (25) lying open in the longitudinal channel (11) of the spindle rail. The longitudinal channel is divided into at least two sections (11,15). One channel part (11) has the open stators (26) and rotors (25), and the other channel section (15) carries the electrical supply lines (37), the control lines and control units (39) or the electro-motors. A shrouding in the second channel section (15) divides it into a high current and low current sub-section. The longitudinal channel is a generally Y-shaped extruded profile, to hold the electro-motors (25,26) in the upper section, and the electrical supply lines (37), control lines and control units (39) in the lower section. Both sections are covered by removable lids (31,33). ADVANTAGE - As there are no motor housings, the mfg. is simplified and requires less material, and the access is improved for maintenance.

Title: Equipment to surface PCB with film(s) - has conveyors to feed to and discharge from vacuum chamber contg. 2 endless belts with devices to apply heat and pressure
Inventor: ANGER WOLFGANG
IPC: H05K3/00
Filed: 1990-08-24
Abstract: A PCB is covered with a film on one or both sides in a vacuum chamber. In the appts. used two continuous belts move together in the vacuum chamber to form the laminating gap between them and a heater acts on the laminate. A prefabricated PCB (12) is moved (8) together with its covering film(s) into the vacuum chamber (2) where the two conveyor belts (6,7) produce the laminating gap (18) between them. Between the two belts (6,7) there is a heater (10) and pressure ram (13) on each side. In operation the laminate is moved into position before the inlet and outlet (3,4) are closed and the vacuum is produced. The film(s) is hot pressed on to the PCB either by admitting atmospheric pressure or even higher pressure to the rams (13). The surfaced PCB is moved out of the chamber by opening its inlet/outlet (3,4) and activating the conveyor table (15). A pair of pressure rollers (16) can also be used in addn. e.g. to apply a further surfacing. The heating in the vacuum chamber (2) can alternatively be by h/f. ADVANTAGE - The equipment eliminates the formation of scrap material (unlike existing appts. for this purpose). It produces high grade laminates at a high output rate.

Patent DE-4103775-A1 (DE)
IPC: E04G9/02
Filed: 1991-02-08
Abstract: In order to reduce its weight, a lining board (1) has at its edges, instead of hollow sections, flat marginal strips (3) that project perpendicularly to the lining skin (2) and that have, in order to increase their stiffness, an area (5) that extends back to the middle of the lining board (1), arranged between their two mutually aligned longitudinal edges (6, 7) that act as a support for the marginal strip (3) of an adjacent lining board (1). In that recessed area (5) are formed flutes or beads (8) that extend in the opposite direction and that are open towards the centre of the lining board. A flat, highly resistant marginal strip (3) is thus obtained, whose beads (8) may be engaged by usual clamps or clips, dispensing with heavy-weight hollow marginal sections.

Patent DE-4123859-A1 (DE)
IPC: B23B33/00
Filed: 1991-07-18
Abstract: The workpieces (3) are held between centres (7, 8) at both ends (10, 11) unmachined at the periphery. To machine the two workpiece ends (10, 11), the respectively opposite end is radially clamped. The radial clamping means (4, 6) are axially retracted at the workpiece end to be machined. Once this workpiece end is machined, it is clamped in a radially centring manner, while the centre (7, 8) is axially retracted. At the opposite, still unmachined end, the clamping means (4, 6) is axially retracted and the end is merely held by the centre (7, 8). Once this end is also machined, it is clamped in a radially centring manner, while the centre (7, 8) is axially retracted. During the machining of the centre area of the workpiece (3), both centres (7, 8) are thus axially retracted from the workpiece (3). The device for carrying out the method has two chucks (1, 2) which have radially and axially adjustable clamping elements (4, 5). One chuck (1) has clamping elements (4) clamping in a centring manner as well as clamping elements (5) clamping in a compensating manner. The clamping elements (4, 5) are radially adjustable independently of one another. Since the locating centre (7, 8) is retracted from the workpiece (3) in the area of the clamping elements (4) clamping in a centring manner, no constraint can occur between this locating centre (7, 8) and the clamping elements (4). The workpiece (3) and the device are consequently not loaded to an inadmissibly high degree. In addition, high true-running accuracy of the workpiece (3) is achieved.

Title: Producing mouldings from plastic scrap - by fusing in homogenising extruder, discharging continuously into base of vessel fitted with plunger, injecting in cycles into cold mould
Inventor: HENTSCHEL MARTIN
IPC: B29C45/54
Filed: 1991-10-09
Abstract: Moulding is produced from mixed plastic scrap by fusing the material in an extruder, feeding it into a suitably shaped mould, cooling, and demoulding. From the extruder the melt is first passed into an intermediate chamber before then being injected in cycles into the mould. Disintegrated plastic scrap of any kind, but with sufficient thermoplastic content to ensure that it can soften under heat to a paste, is fed into a 200-600 kg/hr capacity extruder. The fused mixt. discharged from the extruder is fed continuously into an intermediate container fitted with a spring-loaded top plunger. As the mix is fed into the container the plunger rotates, moves upwards and homogenises the mix. When the container is full the plunger descends rapidly and injects the shot into the mould cavity. The mould can contain e.g. a steel mesh, which is fully encapsulated by the shot; the resultant prod. then having reduced creep properties. ADVANTAGE - It is possible to produce larger mouldings from the scrap than has higherto been possible. It can produce them up to the size of telegraph poles

Patent DE-4138216-A1 (DE)
Inventor: GUTTMANN HANSJUERGEN
IPC: C10L10/00
Filed: 1991-11-21
Abstract: In this process for the addition of ferrocene to fuels or to petrols, improved metering of the ferrocene additive into the combustion chamber of an internal combustion engine or combustion installation is to be made possible. For this purpose, the sublimation properties of ferrocene are exploited by transferring the latter by means of sublimation into a stream of the combustion gas or a part stream thereof and feeding it together with the fuel or petrol present in fine distribution as solid or liquid particles or in the vaporised form to the chemical conversion by combustion. A preferred application is the charging of the combustion chamber of a diesel engine fitted with a diesel particle filter by means of a carrier gas stream enriched with ferrocene vapour in a sublimator.
