Patent DE-2743076-A1 (DE)
Title: Dual system road running and rail guided vehicle - is raised or lowered on transition between free running and track travel
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: B62D1/26
Filed: 1977-09-24
Abstract: The traffic system, esp. for public passenger transport, has steerable sprung road vehicles with cross-guided rollers near the axles and gauge-determining cross-guiding stem pieces on both sides of tracks. Vehicles can run independently on normal roads and also with self steering on tracks. The rollers are held at fixed height with 12-15 cm clearance, while cross-guiding stem piece height exceeds this by 15-20 cm. On crossover from free-running so tracked travel vehicle superstructure is raised higher relative to non-sprung parts and vice-versa.
Patent DE-2806586-A1 (DE)
Title: Solar cell ensuring absolute sealing of collector - has rear face fluid connections and insulation forming closed unit
IPC: F24S10/50
Filed: 1978-02-16
Abstract: A protective glass covers the coated surface of a plate having a layer of absorbent material and canals for the passage of a fluid, to which there are external connections, forming a solar cell. The other side of the absorbent plate is covered by a layer of insulating material. The absorbent plate together with at least one glass cover plate positioned some distance from it, is assembled in an interrupted, closed frame of 'U'-section, to form a separate part of a cell unit. On the rear face of the absorbent plate, outside the zone of the frame, there are two connections. The heat insulation of the rear face is effected by a plate of insulating material which forms a second separate part of the solar cell. The design avoids inefficiency or expensive sealing arrangements. The sealing of the radiation collecting part of the cell is absolute.
Patent DE-2808935-A1 (DE)
Title: Magnesium bi:sulphite boiling acid prodn. for pulping cellulose - using sulphur di:oxide from thermal decomposition of one fraction to increase acidity
Inventor: LOQUENZ HEINZ DIPL ING
IPC: D21C11/06
Filed: 1978-03-02
Abstract: Prodn. of strengthened boiling acid for pulping cellulose with Mg(HSO3)2 from waste gases contg. SO2 from combustion plants, esp. lye burners, involves introducing an absorbent suspension into the gas stream, so that Mg-(HSO3)2 is produced in the first scrubbing stage from Mg-SO3 obtd. from MgO and SO2 in subsequent scrubbing stages. The novel is that part of the Mg(HSO3)2 soln. produced, contg. residual MgSO3, is decomposed thermally to SO2 and MgSO3 and the SO2 formed is contacted with another pt. of the soln., so that the residual MgSO3 in the soln. is converted to Mg(HSO3)2 and also free SO2 passes into soln., whilst the MgSO3 formed is recycled to the absorber. The process avoids the need to use additional gases with a high SO2 content from a roasting process and increases the utilisation of SO2.
Patent DE-2814233-A1 (DE)
Title: Industrial water recovery from settling basin - by overflow container immersed near surface in clean water zone
Inventor: DINNENDAHL MICHAEL ING GRAD
IPC: B01D21/34
Filed: 1978-04-03
Abstract: Water, for uses other than drinking, is obtd. from setting basins by dipping a draw-off container into the basin, with its overflow rim close to the water surface. A pump, installed inside the immersed container or outside the settling basin, extracts water needed for purposes other than drinking. This provides a welcome reservoir for water to be used for purposes other than drinking, at min. cost. It saves the use of drinking water, e.g. for clean-out operations on clarification plant and storm sewage tanks.
Patent DE-2816040-A1 (DE)
Inventor: RESE ARCADIUS
IPC: G07F17/14
Filed: 1978-04-13
Abstract: This monitoring device ensures that, before a deposit (25), for example a two-franc coin, is inserted, the bolt (19) can not be brought out of the open position shown, in which the key (not shown) can not be withdrawn, into the closed position. When a deposit (25) is inserted, the rocker (27) is rotated. If a deposit (25) is too small, it falls through. However, if the deposit is the right size and the rocker (27) is rotated, the pawl (29) is released. The bolt (19) can consequently be rotated into the closing position, in which the key can also be withdrawn. As a result of the rotation of the bolt (19), the pawl (29) is also moved in an anti-clockwise direction and retains the deposit (25) in the deposit channel. When the bolt (19) opens, the deposit (25) then falls downwards. Because the pawl (29) is loaded by a spring (67), the force of this spring ensures that the pawl engagement cannot be released by blows on the lock. The width of the deposit channel can be adjusted according to the deposit size by the displacement of the guide (45). <IMAGE>

The impednace (Z A) of the aerial element (1) at its terminal (3) has a real component (RA) smaller than the feeder (9) characteristic impedance (ZO). Its imaginary component (BA) is capacitive. An intermediate line (2) is connected between the aerial terminal (3) and the matching network (5), whose electrical length transforms the aerial (1) impedance ( ZA) to the input of the matching network (5) whose impedance ( ZA) is conjugate with the aerial impedance (+ ZA).

Title: Working cylinder with braking function - has internal flow restrictor channel shaped to ensure braking towards piston travel end
Inventor: BUCHER JOSEF DIPL ING
IPC: F15B15/22
Filed: 1978-07-08
Abstract: The actuating cylinder ensures that the movement of the piston towards the cylinder is braked. The velocity reduction can be achieved especially to a final velocity less than 5 centimetres per second. This system operates reliably over years in continuous operation. Braking is only slightly affected by the fluid temperature. The working fluid flows out of the cylinder chamber (4, 10) through a channel (16) leading through the cylinder wall (15). This channel opens along a braking section (17) of the path of the piston (2) towards the end (3) of the cylinder chamber. The opening of the channel is a tapered groove on the cylinder wall which runs a axial direction. the opening of the channel can be a number of holes aligned.

Title: Precision drive circuit for engine fuel-injection valve - has two series switches controlled by constant-width and variable-width pulses
Inventor: KAWAMURA YOSHIHISA
IPC: F02D41/20
Filed: 1980-01-03
Abstract: The drive circuit has a d.c. supply (+V) and a first pulse generator (16) generating first pulses of constant width in synchronisation with the rotation of the engine. A second pulse generator (20) generates second pulses whose width depends on the amount of air introduced into the engine. A delay (18) delays the appearance of the second pulses until after the first pulses. A first switch (22) in series with the magnetic coil connects this coil to the d.c. supply so that a small current flows through the coil such that the valve does not open in response to the first pulses. A second switch (26) in series with the coil connects the coil to the d.c. supply so that a larger current flows allowing the valve to open in response to the second pulses.
