Patent DE-3151111-A1 (DE)
Title: Arrangement for controlling the air/fuel ratio of an internal combustion engine
Inventor: MOROZUMI TAKURO
IPC: F02D41/34
Filed: 1981-12-23
Abstract: An arrangement for controlling the air/fuel ratio of an internal combustion engine contains an intake channel, a carburettor, an On/Off solenoid valve for correcting the air/fuel ratio of the air/fuel mixture fed to the carburettor, an O2 sensor for detecting the oxygen concentration in the exhaust gases and a feedback control circuit which responds to the output signal of the O2 sensor in order to generate pulses in order to modulate the solenoid valve so as to correct the air/fuel ratio. An engine speed detecting circuit generates an output signal which changes with the engine speed. A frequency convertor circuit responds to the output signal of the engine speed detecting circuit in order to convert the frequency of the pulses, by which means the solenoid valve is prevented from resonating with the vibrations of the engine and with the pulsation of the fed-in air. <IMAGE>

The second compressor is connected to this heat exchanger and the seawater-cooled condenser to form a closed circuit, in which a refrigerant is operating. The liquefaction plant can be switched over between an open plant having only one circuit, and a cascade arrangement of two circuits.
Patent DE-3226462-A1 (DE)
Title: Device for pivoting a chassis-frame part of a material-handling truck
Inventor: VEITH GUENTER
IPC: B66F9/06
Filed: 1982-07-15
Abstract: So that unevenness in the floor, for example door sills, can be driven over by material-handling trucks, in particular high-lift fork trucks, having a loading surface arranged at only a slight height above the floor, without the chassis frame coming into contact with the floor, the chassis frame must be raised in particular in the centre area situated between the front and rear running rollers. In order to avoid complicated lever-bar constructions of known material-handling trucks in which the loading surface maintains its horizontal position or even constructions in which the loading surface assumes a sloping position during the raising of the chassis frame, the device for raising the chassis frame according to the invention has a construction in which, on both sides of the two profiled stanchions (2, 3) forming the fixed mast (1), one pressure cylinder (11) each is linked to the chassis-frame part (5) carrying the fixed mast (1), by means of which pressure cylinders (11) the chassis-frame part (6) situated beneath the load carrier (7) and guided on the profiled stanchions (2, 3) of the fixed mast (1) by means of rollers (13, 14, 15) is pivoted, the lifting cylinder (8) being linked to the pivotable part (6) of the chassis frame. <IMAGE>

Filed: 1982-08-20
Abstract: Contact making devices in the form of cavities (21) are provided in plastic components for electrical kits (assembly kits). A self-locking contact spring (10) which is constructed symmetrically about a longitudinal axis is inserted into said contact making devices. This contact spring (10) is constructed with a head (10a) which is in the form of an arrow head, a straight central part (10b) and barbs (10c) which are directed obliquely upwards and downwards. Supporting ribs (22) are constructed in the cavity (21), as a result of which gaps (23) are formed between the contact spring head (10a) and the side wall of the cavity (21), in order to clamp in bare conductor ends (11 and 12). An upwardly projecting supporting peg (pin) (25) is constructed on the base of the cavity (21) in order to hold the straight contact spring parts (10b) a narrow channel (26) being provided in the base of the cavity (21), immediately adjacent to the supporting peg (25), for a bare conductor end (13) to be passed through. This bare conductor end (13) is clamped in between the outside of the supporting peg (25) and the inner surface on the straight contact spring part (25b). The contact device (21, 10) can be installed especially into the ends of coupling pegs (2a and 2b) on an electromagnet (1) having a magnet winding (6) whose ends (as shown in the case of 13 in Figure 2) are connected to the contact spring (10). Alternatively, the contact device can be installed in a cylindrical body, which is constructed as a commutator, and can be used to make contact with bare ends of conductors which connect commutator laminates to magnet windings on a rotor having corresponding contact devices. <IMAGE>

Title: Voltage regulator for an AC magnetic generator
Inventor: HAUBNER GEORG
IPC: H02J7/14
Filed: 1982-08-24
Abstract: A voltage regulator is proposed for a permanent-magnet-excited AC generator, which is used to regulate the voltage of a DC network and to charge an accumulator battery, the no-load voltage of the accumulator battery being intended to be used for regulation. The AC generator (14) is in this case connected via a rectifier arrangement (20) to the DC network (19) with the accumulator battery (18), and can be bridged by a bidirectionally active thyristor circuit (23, 24). The control junction of the thyristors (23, 24) can be bridged by a control transistor (26, 27) whose base is in each case connected to a voltage divider (28, 29) which is connected in parallel with the thyristor (23, 24). The gate connection (23a, 24a) of the thyristors (23, 24) is furthermore connected via the switching path of a threshold-value switch (32, 33) to the positive potential of the DC network (19), in that the threshold-value switch (32) becomes conductive when a specific DC voltage is present in the DC circuit (19). The voltage regulator (10) can preferably be used in motor vehicles which have a magnetic generator driven by an internal-combustion engine, and a DC network with an accumulator battery. <IMAGE>

Title: Specimen loading device
Inventor: NEY JANUSZ
IPC: G01R31/40
Filed: 1982-12-03
Abstract: The invention relates to a specimen loading device for testing power supply devices with an adjustable electronic load. Such specimen loading devices must be adjustable within a wide range and independent of the voltage of the specimen. For this purpose, the invention provides that electronically adjustable load resistances 1, 2, 3, 4 can be connected in parallel with the respective power supply to be tested via a selection circuit 5 with binary staggering in accordance with the number of bits required for the adjustment of coarse ranges. A voltage controller is simultaneously supplied with the adjusted actual current value, via a selection circuit, and with the nominal current value, adjustable by means of twice the bit number with respect to the bit number of the coarse range, as voltage values via a digital/analog converter 7. The difference amount of actual and nominal value is supplied to a current amplifier 8 which is fed from an auxiliary source UH and which, in turn, acts on the respective connected adjustable load resistances 1, 2, 3, 4 in a back-controlling sense. <IMAGE>

Title: Manually operated labelling unit
Inventor: FUJITA MITUO
IPC: B65C11/00
Filed: 1983-01-26
Abstract: In a manually operated labelling unit with a lateral aperture in its casing, through which the feed mechanism for the label bearing strip is accessible, a guide is arranged between the bearing strip support and the bearing strip deflection device in the section of the path of the bearing strip opposite a feed drum, in such a way as to be movable in relation to the outside perimeter of the feed drum. This guide is pivotable about its centre and has two pressure elements which extend sideways from its centre and which press the bearing strip against the drum perimeter. When the bearing strip is pulled, the upper pressure element comes into contact with the feed drum: this pressure element has a tang-like extension which partially overlaps the side wall of the feed drum on the side pointing towards the aperture in the casing. The bearing strip is held securely on the feed drum by the guide.
Patent DE-3303193-A1 (DE)
Title: Vertically adjustable table, in particular for video workstations
Inventor: FLEISCHER WILLY
IPC: A47B9/06
Filed: 1983-02-01
Abstract: A vertically adjustable table, in particular for video workstations, with a table top and a table frame with at least one table column having an upright column outer tube and a column inner tube telescoping therein with a vertical-adjustment device for the column inner tube supporting the table top. On the inside, the column inner tube has a toothed rack and a longitudinal slot. At least one pinion arranged in the column inner tube on a bearing shaft meshes with the toothed rack, the bearing shaft being mounted in the column outer tube and being passed through the longitudinal slot into the column inner tube. An easy-running action is thereby obtained for the telescoping column inner tube. In addition, a release linkage can be mounted in the column inner tube next to the toothed rack. The release linkage works on at least one pawl in the column inner tube, in the course of which the pawl comes with a locking tooth out of its column inner tube and drops into locking recesses in the column outer tube in accordance with the vertical adjustment and can also be disengaged from the locking recesses by actuation of the release linkage. <IMAGE>

Patent DE-3308507-A1 (DE)
Title: Axial piston pump
Inventor: GRIESE KLAUS DIPL ING
IPC: F04B1/32
Filed: 1983-03-10
Abstract: The axial piston pump has a swivel disc (27), the swivel axis (23) of which is offset in relation to the longitudinal axis of the cylinder drum (15) by the eccentricity (e) towards the upper dead centre (OT). It is thus brought about that, with a loaded pump, the swivel disc (27) is automatically set out by the resulting piston pressure forces. A spring (32), which acts on the swivel disc (27) via a body (30), serves as return force. The force of the spring (32) is designed in such a manner that, at very small pressures up to approximately 10 bar, the axial piston pump is kept in its minimum delivery position. Only when the consumer is switched on, does the system pressure rise, and the then predominant piston forces, as a result of the kinematics just described, adjust the axial piston pump to the delivery quantity which can be adjusted with a spindle (34). In this manner, a very simple and cheap adjustment arrangement for an axial piston pump is achieved. <IMAGE>
Patent DE-3309390-A1 (DE)
Title: Drinking vessel for an infant
IPC: A61J9/00
Filed: 1983-03-16
Abstract: The drinking vessel comprises a dimensionally stable lower part (1) especially made of plastic, and a similar upper part (2). The upper part is integrally formed or detachably connected to the teat (3) as a rigid-soft combination. A bag-like flexible inner part (4) especially made of a film-like plastic material is suspended in the lower part (2), the free edge of this inner part being retained in a suitable manner. This edge (14) is expediently clamped between the lower part (1) and the upper part (2). The extremely flexible material of the inner part (4) prevents formation of a reduced pressure on evacuation of the drinking vessel by the infant, so that the infant can always suck with the same sucking force, and sucking-in of air is at the same time avoided or can at least be made avoidable. For this it is necessary for the outer surface of the inner part (4) to be exposed to atmospheric pressure and to be accessible, if required, for the purpose of compression. <IMAGE>
