Title: Measuring IC engine injection pump fuel delivery - uses successive injection of fuel into cylindrical measurement container
Inventor: HERZOG PETER DIPL ING DR
IPC: G01F25/00
Filed: 1980-10-15
Abstract: The method of measuring the fuel quantity delivered by a combustion engine fuel injector pump piston involves injecting a test fluid, e.g. fuel, into a cylindrical test container during a defined time or a given number of piston strokes. The corresp. arrangement gives observation error-free results and other error sources and the operating time are considerably reduced compared to conventional arrangements. Several measurements are conducted successively in the same container without intermediate emptying. Each involves measuring the level of fluid at the beginning and end of pumping and determination of the achieved level difference. Alternatively, the vol. of fluid to be delivered is predetermined and the number of piston strokes required to deliver it counted. Optoelectronic level measurement is preferred.

Title: Atomiser for atom absorption spectrometer - extends dynamic range by regulating inert gas flow and temp. from spectrometer output
Inventor: HUBER BERNHARD
IPC: G01N21/74
Filed: 1980-12-17
Abstract: An atomiser for use in atom. absorption spectroscopy enables an inert gas to be passed around and inside a graphite tube which is electrically heated. It enables the dynamic measurement range to be extended compared to conventional frameless atom. absorption spectrometers and results in reduced measurement times. During measurement the inert gas flow rate can be varied between nil and a higher level. The temp. of the graphite tube can also be regulated during the measurements. Regulation of these signals is performed using the output signal of the atom absorption spectrometer. The spectrometer signal is input to an amplifier with a linear or curved characteristic. The amplifier drives an electropneumatic flow regulator controlling the flow of gas into the graphite tube.

Title: Vehicle windscreen water trap rail - is fitted on inflatable strip which inflates when wiper motor is operated to push rail outward
Inventor: RODRIGUEZ HUMBERTO
IPC: B60J10/244
Filed: 1980-12-23
Abstract: The vehicle windscreen water trap rail is formed of an elastic profiled strip (17) which fits into a trough (15) in the roof support (9) at the side of the windscreen (11). The strip has a hollow tubular centre (19) and has a rail projection (23) which forms the water trap. The hollow centre is filled with liquid so that when the windscreen wipers are switched on a compressor pumps liquid into the strip so that the water trap rail (23) is pushed outwards. Water from the screen is directed towards the vehicle roof, thus keeping the side windows clean. When the wipers are switched off the liquid is drained out to allow the rail to sink into the trough, thus minimising wind resistance.

Title: Broadcasting machine
Inventor: ORTH GUENTER
IPC: E01C19/20
Filed: 1981-01-20
Abstract: The broadcasting machine, which can be designed as a towed trailer or as a self-propelled unit, comprises a trough tipper which, in the bottom of the tipper trough, has a delivery slot which can be closed by a broadcasting flap which is preloaded into the closed position. This broadcasting flap has imparted to it, by means of a motor drive, oscillatory movements composed of pendulum oscillations about an axis transverse to the direction of travel and of oscillations in the longitudinal direction of the axis. The oscillatory drive is formed by a motor-driven driving disc which acts via cam elements on a pressure disc which is thereby raised and displaced sideways. The pressure roller is mounted on a projecting plate of the broadcasting flap. The oscillation frequency and amplitude can be varied by changing the cams of the driving disc and, in addition, by changing the position of the drive shaft supporting the driving disc.

Title: Method for regulating the charging circuit of a battery charger, and an electronic circuit for carrying out this method
Inventor: STEFFENS FRANCOIS
IPC: H02J7/00
Filed: 1981-05-13
Abstract: In accordance with this method, the voltage (VB) is measured at the connections of the battery and is compared with a reference voltage (VR) by means of a differential amplifier (DA) which supplies at its output a signal which is proportional to the voltage (VB) of the battery. This current is passed to a capacitor (C) when its voltage reaches a given threshold value, makes a transistor (T) conductive, as a result of which a current is passed through a relay (RL) which closes two interruptors (I1, I2). The closing of the interruptor (I1) triggers the discharging of the capacitor (C) through a resistor (RD), and the closing of the interruptor (I2) connects the battery to the charging circuit. When the voltage of the capacitor (C) falls below the threshold value of the transistor (T), this ceases to be conductive and the interruptors (I1, I2) are opened. <IMAGE>
Patent DE-3120899-A1 (DE)
Title: Stopping device for the drive spindle of angle grinders
Inventor: BRAUN ROLAND ING GRAD
IPC: B24B23/02
Filed: 1981-05-26
Abstract: The invention relates to a stopping device for the drive spindle of angle grinders, in which the motor-side drive pinion drives a ring gearwheel which is arranged on the drive spindle and contains at least one cutout for the engagement of a stopping bolt. Constant raising and lowering (ski-jump effect) of the stopping bolt on actuation during running or coasting of the ring gearwheel are to be avoided in the case of said stopping device. This is achieved in that on the ring-gearwheel surface located within the toothed wheel rim there is arranged a stopping disc such that it can rotate concentrically with respect to the drive spindle and is secured with respect to axial displacement, said disc containing a through-passage bore which is located on the same radius as the cutout in the ring gearwheel and is intended for the stopping bolt, and in that the stopping disc is provided with two stops which are offset with respect to each other in the circumferential direction, correspond to a fixed stop in the machine housing and establish the angle of rotation of the stopping disc such that one stop of the stopping disc, when the drive spindle is rotating, comes to bear on the fixed stop and thus prevents the stopping bolt from penetrating into the cutout of the ring gearwheel and, when the drive spindle is at rest, releases the through-passage of the stopping bolt to the cutout once said spindle has rotated backwards, counter to its direction of rotation in the operating state, until the other stop abuts on the fixed stop. <IMAGE>

Patent DE-3126799-A1 (DE)
Title: Method for applying lubricants to metal working surfaces
Inventor: KOLE RICHARD PAUL
IPC: F16N17/00
Filed: 1981-07-07
Abstract: The invention relates to a motor vehicle door lock with a fork member (1) and a detent pawl (2). The fork member (1) has a preliminary locking limb (3) and a main locking limb (4). The detent pawl (2) has a detent pawl lever (5) and, attached thereon, a catch (6). During the closure movement of the motor vehicle door, first the preliminary locking limb (3) can be engaged from behind by the catch (6) in the preliminary locking position and, thereafter, the main locking limb (4) can be engaged from behind by the catch (6) of the detent pawl (2) in the main locking position. As the fork member (1) moves from the preliminary locking position into the main locking position, the preliminary locking limb (3) in this case lies in a guiding manner on the detent pawl lever (5). It brings the catch (6) into bearing contact on the main locking limb (4). An impact between catch (6) and main locking lever (4) disturbing the control of the movement is in this way avoided. <IMAGE>

Title: Luggage compartment insert for cars
Inventor: KRUEGER HELMUT
IPC: B60R13/01
Filed: 1981-07-11
Abstract: Luggage compartment inserts for cars serve to protect the interior fittings of the car, are intended to be capable of being folded up and to only take up a small amount of space when folded up and to be capable of being installed in the car with just a few manipulations. This requirement is met by a luggage compartment insert which is composed of a floor plate (1) which on its upper side has guides (19, 20) arranged on both sides for the insertion of side walls (2, 3). At its front side the floor plate (1) forms a receiving portion (25) which runs transversely to the guides and into which can be inserted a front wall (4) or a further, second floor part (2) which extends the first floor part (1), is provided with corresponding guides (19, 20) for the side walls (6, 7) and at its front end has a corresponding receiving portion (25) for the front wall (4) and at its rear end has a fastening leg which can be latched into the receiving portion (25) of the first floor plate (1). The side walls (2, 3; 6, 7) are connected to one another in their upper region via cross-ties (8) and in their front region are held in perpendicular guides (28, 29) constructed on the front wall (4). <IMAGE>
Patent DE-3144132-A1 (DE)
Title: Saw for cutting branches of trees
Inventor: SCHMIERER HEINZ DIPL ING
IPC: A01G3/08
Filed: 1981-11-06
Abstract: A description is given of a saw for cutting branches and trees, which comprises an internal combustion engine arranged at one end of a telescopic tube and a rotatable telescopic shaft which is connected to the engine by a centrifugal clutch, is passed through the telescopic tube and is connected to a gearbox at the other end of the telescopic tube, the said gearbox converting the rotary motion of the telescopic shaft into a reciprocating motion of a saw blade. In addition, the new saw has a safety clutch, which is inserted into the operative connection between the internal combustion engine and the saw blade in order to limit the power which can be transmitted. The torque transmitted can thereby be limited to a predetermined value low enough to avoid damaging the drive components. The new saw therefore has the advantage that abrupt loads on the parts transmitting power between the driving engine and the saw blade, such as those which can arise when the saw blade becomes stuck, cannot lead to damage, which would be disadvantageous.

IPC: F16D59/00
Filed: 1981-12-22
Abstract: The invention relates to a safety device on a two-handled power saw, in particular a chain saw, which device is equipped with a brake acting on the drive wheel for a cutting tool. It is known to bring the brake into a disengaged position by means of a lever arrangement counter to the force of an energy storing device, in order to bring it back into its engaged position on the drive wheel in dangerous situations by means of a release device actuated by a button in the rear handle, in order to stop the cutting tool. According to the invention, it is provided to bring the brake into a stable disengaged position and to provide a release device comprising a release pin which is displaced into a starting position counter to the force of a further energy storing device. In this starting position, the release pin is retained by means of a catch which can be actuated by the button, engages, when the button is pressed down, on the release pin in a manner subjected to force and secures the latter, and which frees the release pin when the button is relieved of the load, which then transfers the brake into its engaged position under the force of the further energy storing device.

Title: Frame structure suitable for multiplexing signals of very different bit rate
Inventor: BARTEL WILLY DIPL ING
IPC: H04J3/16
Filed: 1982-01-23
Abstract: To multiplex a fast signal with a bit sequence of 68734.375 to 68750 kbit/s with a slow signal with a bit sequence of 2048 kbit/s to form a multiplex bit stream of 71040 kbit/s, 33 bits of the fast signal are in each case combined with one bit each of the slow signal to form a sector which is repeated 248 times in the frame. The frame is preceded by 12 additional bits for signalling clock adaptations carried out and for alarm signals and after 124 sectors 12 additional bits are inserted for frame alignment so that the frame contains a total of 8456 bits with a frame period of 119.03  mu s. Of the 12 additional bits at the beginning of the frame, 5 bits are in each case used for signalling the clock adaptation for the fast and, respectively, slow signal so that the following different code words are obtained with bit interleaving of the two signalling bit groups: AO, BO: quasi-synchronous state of both signals, AO, B+: fast signal quasi synchronous, clock adaptation for slow signal, A+, BO: clock adaptation for fast signal, slow signal quasi synchronous, A+, B+: clock adaptation for both signals. <IMAGE>
