Patent DE-2801001-A1 (DE)
Title: Agricultural prod. grinder rotor - has fan discharging ground material into mixer returning surplus air into grinder feed hopper via bag filter
Inventor: FRANZEN GEROLD
IPC: B02C13/288
Filed: 1978-01-11
Abstract: The grinder rotor is combined with a fan rotor, so that the ground material discharge through a pipe (16) is transported into the fodder mixer (17). The surplus air from the closed mixer vessel is discharged through the head chamber (19) to which a bag filter (20) is connected. The pressurized air seeps through the fabric of the filter, and solid particles such as flour are returned to the feed hopper (6) of the grinder via a hose connected to the other end of the filter bag. The hose (14) connects to the feed hopper (6) by a Venturi suction assembly fitted in an intermediary neck (11). The neck has also a connection (15) with the suction side of the fan. The resulting suction in the neck (11) results in a mixture of the flour returned through the hose (14) with the fodder to be ground.

Title: Anti-explosion screen for fuel containers - is made of two layers of expanded or perforated metal pressed together (SW 20.2.78)
Inventor: SZEGO ANDREW
IPC: A62C3/06
Filed: 1978-01-13
Abstract: Two sheets of metal are made from expanded or perforated metal so as to have offset edges. The sheets are laid over each other so that the perforations are staggered, and the resultant composite metal has a greater thickness and lower density. The sheets are pressed together and cut between rollers and the combined sheets may be rolled up or folded into stacks. The sheets are inserted inside fuel containers to minimise the effects of explosions.

Title: Spring mounting for lorry tipping cab - has torsion spring mounted about offset axis linked to thrust levers
Inventor: PUETTER HENNING ING GRAD
IPC: B62D33/07
Filed: 1978-02-10
Abstract: The lorry cab is tipped about a raised axis and is fitted with a transverse torsion bar (3) to provide some resistance to the action and hence ease the subsequent raising of the cab. The torsion rod axis is offset from the tipping axis and is linked to the chassis by a short thrust lever (7) operating against a stop (61) on the chassis. The stop is formed by a convex end of an adjusting bolt so that the action of the spring can be adjusted to suit the weight of the cab. The lever rolls over the end of the bolt so that a simple linkage is obtained.

Patent DE-2824990-A1 (DE)
Inventor: BEGUIN PIERRE-ANDRE
IPC: G04C3/00
Filed: 1978-06-07
Abstract: An electronic watch with mechanical display is more easily altered or corrected by sharing the display driving tests among a plurality of duel rotation sense motors. Such an arrangement enables practicable obtaining of a perpetual calendar in such a watch. A first stepping motor drives the seconds and minutes displays Figure 1, and the second stepping motor drives the hours and calendar display. Drive signals for the motors are derived by respective frequency dividers from a crystal controlled oscillator. When setting, a selector 8 is operated to select the unit to be corrected and in response to operation of a switch 9 or 10 the appropriate motor is driven forward or backward at a slow or fast rate. Memory circuits enable automatic adjustment for the number of days in the current month. <IMAGE>

Title: Level interrupt free HF transmission between vehicle and line - using two antennae fed via high and low pass filters respectively giving opposite phase shifts
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: B61L3/22
Filed: 1978-09-12
Abstract: The radio communications system uses several, e.g. two aerials located one behind the other in the direction of travel of the vehicle. These aerials are inductively coupled to a two-wire line laid along the road and having its wires crossing over at intervals. The signals being sent are passed via e.g. two parallel transmit channels to the two aerials. The first channel contains a low pass filter, and amplifier and a bandpass filter. The second channel contains a high pass filter, an amplifier and a bandpass filter. The phase shifts in the bandpass filters and amplifiers are the same for both channels.

Title: Wind driven power generator with horizontal shaft - has impeller gear wheel driving several generator pinions spaced round it to reduce stresses
Inventor: ROGGE ERNST
IPC: F03D15/10
Filed: 1978-09-16
Abstract: The generator has an impeller (5) with propeller type blades rotating on a horizontal shaft (6). The impeller and shaft are mounted at the top of a vertical mast (2). The shaft drives a large gear wheel (1) directly coupled to it at the top of the mast. A large number of pinions (4) are spaced evenly round the gear and each is coupled directly to a small generator (3). The outputs of the generators are connected in parallel. As the drive is taken from the whole circumference of the gear wheel (1) the maximum load on the gear teeth is reduced and they can be made to smaller dimensions.

By using swivel drawers in place of normal drawers means that less space is required for the cupboard depth. The drawers pref. swivel about a common axis e.g. a stand pipe(16) and are connected in each front corner of the drawer. The cupboard depth need only be slightly greater than the width of the drawers.

Title: Program controlled domestic washing machine - with load cells to adjust program to washing weight
Inventor: GLASMACHER PETER DIPL ING
IPC: D06F33/36
Filed: 1978-10-13
Abstract: Electronically controlled domestic washing machine is fitted with electromagnetic transducers in the feet which measure the dead weight of the drum, the weight of the washing put in the drum and the weight of the water admitted by a pump. The output signals are passed to a program unit which shuts off the pump when the required level is reached, calcualtes the amount of washing powder to be added, and sets the program. In the case of a light load, it initiates a quick program. During the spinning process, the transducer responds to any unbalance by uneven distribution and stops the motors until the washing has been evened out. Fully automatic wash process is always automatically adjusted to suit the load.

Title: Distance setting indicator for viewfinder - includes adjustable size illuminated frame corresponding to spacing
Inventor: STIEFEL PETER ING GRAD
IPC: G03B13/20
Filed: 1978-11-20
Abstract: A distance setting aid is intended for use in a camera.

Title: Mains voltage stabiliser for battery charger - uses ferro-resonant transformer with load winding on outer limbs
Inventor: STEINIG WALTER
IPC: H02J7/00
Filed: 1979-03-05
Abstract: Inherent voltage regulation to compensate for mains voltage variations is achieved by employing a ferro-resonant core type transformer between the supply and the charger. The primary (3) and resonant (4) winding are both on the central limb (1b) of the transformer core (1). Magnetic shunts (5) are placed between the windings. The output, or load, winding is divided into two coils (6), one on each outer limb (1c) of the core in a position in line with the resonance winding. Laminations (7) to increase the leakage flux are placed between output and resonance windings. The construction eliminates the need for a separate choke, specially tuned, in series with the output winding. To improve the output winding cooling an air gap (8) can be allowed between the external limbs of the coils (6) and the outer core limbs (1c).

Title: Float flowmeter with optical system for explosive conditions - has small float and pulsed optical position detection system
Inventor: LUTZ KURT DIPL PHYS
IPC: G01F1/22
Filed: 1979-06-15
Abstract: A float flowmeter with an electro-optical float position sensor is esp. for driving a regulator. An optical system has a light source and a light sensitive receiver element which can be obscured by the float. A float of less than 10 millimetres dia. enables an low-power optical system suitable for explosive conditions to be constructed. The optical system is switched on intermittently for intervals chosen to keep the time-averaged diode light source supply current below a given value. The time between two successive switched-on intervals is smaller than the time for which the light sensitive element is obscured when the float passes through the optical path. The optical system operates outside the visible region, pref. in the infrared region of the spectrum.
