Patent DE-2841693-A1 (DE)
Title: Ventilation device for connection to container - is evacuated and filled by suction and has inlet pipe with valve operated by level sensor
Inventor: BRISACH JUERGEN
IPC: G01F23/30
Filed: 1978-09-25
Abstract: A container is evacuated through a vacuum pipe, and is filled through a suction pipe. The device has a ventilation valve which controls the connection of the container inside with the atmosphere, and a filling level indicator operated by a sensor controlled by the filling level. The filling level sen sor (50') is coupled with the ventilation valve and opens it as soon as the filling level rises above a specified height. The air flowing through the inlet connection (76') generates an audible signal. The absolute pressure in the container ranges from 0.0 to 0.4 bar, or from 0.1 bar to 0.8 bar. An acoustic signal may be produced by a resonant body.

Title: Tilting suspension for rail guided vehicle - has angled struts on bogies causing carriage body to lean towards centre of curve
Inventor: BERTELSBECK HELMUT
IPC: B62D1/26
Filed: 1978-09-26
Abstract: The suspension for a rail vehicle has the bogeys at each end pivoted about vertical bearings in such a way that the carriage tilts into the corner by a controlled amount. This provides added cornering stability, with a control to ensure that each bogey turns by the same amount. The system provides cornering stability on tramways where the track cannot be tilted. Each bogey is turned by half the angle required for the curve, while angled suspension struts control the lateral force on the suspesion.

Title: Rolling mill train for billets, bar or rod - has one or two cages each contg. three work rolls adjustable radially w.r.t. billet axis
Inventor: BRAUER HANS
IPC: B21B1/20
Filed: 1978-12-23
Abstract: The mill is pref. used for roughing or intermediate rolling; and includes at >=1 reversible cage possessing >=3 work rolls located at intervals of 120 degrees in a star-shaped formation round a single longitudinal gap contg. the rolling axis (a) and through which the billet or bar passes. The axis (a) of the gap and the workpiece remain fixed, whereas each roll can be adjusted radially w.r.t. axis(a). Each roll pref. has a convex periphery, the three peripheries forming the roll gap; and the pref. mill uses either one cage; or two cages where the rolls in the second cage are displaced 60 degrees w.r.t. the rolls in the first cage. When only one cage is used, a tilter turning th billet on its longitudinal axis is pref. used on both the inlet and exit sides of the mill. Used e.g. for hot rolling a square billet in nine passes to make a hexagonal bar the mill has low initial cost but high productivity.

Title: Meat salting machine - with two pairs of needle rollers for meat actuated brine injection
Inventor: SOMMER HANS
IPC: A23B4/28
Filed: 1979-12-19
Abstract: A machine for the salting of pieces of meat consists of a conveyor which feeds the meat in the horizontal gap of two pairs of needle rollers. Two are mounted on a spring-loaded bracket on each side of the gap. The hubs carrying the follow needles revolve on a stationary hollow spindle which supplies the brine into the gap between hub bore and spindle. A flat on the spindle allows the needle bore to be uncovered only when the needles have penetrated the meat.. This results in a quick and uniform injection of brine which requires no vacuum. Loss of brine is eliminated and the meat cannot adhere to the needles.

Title: Thermally driven pendulum as power unit - has closed tube extending into liquid-filled evacuated vessel heated to produce pendulum motion
Inventor: MEYER ERNST
IPC: F03G7/04
Filed: 1980-03-14

Title: Linear induction motor drive for model railway layout - has high frequency motor component laid between rails and operated from controller
Inventor: GOEPFERT MAX
IPC: A63H19/10
Filed: 1980-05-21
Abstract: The models are powered using a frequency of approx. 400 Hz derived from the mains and controlled by a model layout controller desk so that to slow the models an increase in operating frequency is used and to speed up vice versa. A single linear motor (4) is located between the lines (8) of the layout and comprises a ferromagnetic base material with a good conducting non-ferrous top layer which brings the height of the linearly located motor to the same level as the track lines (8). The track lines (8) are powered and carry the current used for the phase shift capacitor, motor main and auxiliary windings plus the reversing relay which constitutes the single phase comb structured motor unit located in the drive model and which reacts to the central linearly motor component between the layout's lines (8). By using higher frequency operation and frequency changing for speed control the motor items are smaller and lighter in construction.

Title: Coil assembly of tinned copper wire - uses coating of which is removed at ends down to tin before completing winding
Inventor: GRUETZNER DIETER
IPC: H01F27/28
Filed: 1980-09-13
Abstract: The coil is made from copper wire which is first tinned and then coated with a non-solderable enamel layer. Those sections of the tinned enamelled wire that will form the connection ends of the wound coil have the enamel removed by abrasion to expose the tin. The winding of the coil is then completed and the connection ends bent as required. The advantage obtained is that the coil needs no further tinning which reduces production time and costs. The coil can be provided with a magnetic core in the normal way.
