Title: Electrical line break monitor - has relay switching to monitoring stage via rectifiers and inductance
Inventor: DUESING HANS-JOACHIM DIPL ING
IPC: H04M3/28
Filed: 1977-09-30
Abstract: A switching circuit is provided to maintain a check on the condition of two conductors connecting monitoring stages. The two conductors connect to one monitoring stage with switching relay over rectifiers and an inductance. A second relay connects over an inductance with one line.

Title: Two stage IC engine fuel pump - has both stages mounted on common bearing sleeve to transmit drive between them
Inventor: KEMMNER ULRICH DIPL ING
IPC: F04D29/043
Filed: 1977-10-12
Abstract: The rotor (7) of an electric motor turns on a bearing sleeve (12) on a stationary shaft (15). A coupling sleeve (35) attached to the rotor has a projection (37) which fits into a groove (39) in the rotor (21) of a radial piston pump (4).

Title: Preventing coke deposition in thermal processing of hydrocarbon(s) - by addn. of sulphur-contg. salts
Inventor: STOLJAR GENRICH LVOVITSCH
IPC: C10G9/16
Filed: 1977-11-10
Abstract: Thermal processing of crude hydrocarbon mixts., e.g. heavy petroleum fractions of gas oil type, is carried out in presence of steam and an inhibitor consisting of a sulphur-contg. salt of an alkali(ne earth) metal.

Title: Multiposition suction conveyor system - has filters blown clear in sections and suction bus-pipe to fan intake union
Inventor: MUECKE WALTER ING GRAD
IPC: B65G53/24
Filed: 1977-12-14
Abstract: The multi-position pneumatic conveyor transports powdery material by suction from a hopper to a number of stations. Each station has material separator with a bottom discharge flap to a user unit, together with a discharge air filter which can be blown clear in the reverse direction, separating a material chamber from a pure air chamber. A common fan generates the suction and flows the filters clear, having a suction buspipe connected to the pure air chamber, also a flushing buspipe. Valves at each station open the suction buspipe for suction and flushing and shut it off to discharge the material handled. The filter is blown clear in sections, and the suction buspipe is fixed to the fan intake union. The separate flushing pressure buspipe is connected to a two-way valve, allowing the fan discharge union to be connected to atmosphere when transporting the material, or to this buspipe for flushing. The station valves have plugs shutting off the flushing pipe in order to discharge material but which are otherwise open.

Title: Chipboard backing plate recycling - speeded up by flights of continuously moving transfer conveyor
Inventor: BOSSLER FRIEDRICH ING GRAD
IPC: B27N3/22
Filed: 1979-07-19
Abstract: Flexible backing plates, carrying a chipboard mat from a moulding station to a press station, are transferred from a continuously moving conveyor with flights to the flights of an intermittently moving conveyor which takes them to the press.

IPC: H03C1/02
Filed: 1979-12-15
Abstract: The current source comprises a transistor with a resistive voltage divider connected to its base and an emitter resistor connected to its emitter. A controlling signal voltage is applied to its base. The collector current provides the modulating signal for an amplitude modulator.
