Title: Energy storage flywheel on electric motor - is connected to rotating stator to permit regenerative braking
Inventor: BEYER MANFRED
IPC: H02K16/00
Filed: 1977-03-22
Abstract: In the machine the stator as well as the rotor can revolve, but a large inertia mass or flywheel (7) is attached to the stator. The stator is intended to act as a store by converting into kinetic energy such energy which would otherwise be lost as heat when starting or stopping the motor. During breaking of the rotor the energy is transferred from the load into the mass of the stator which then runs as a flywheel. When restarting the drive this stored energy can be converted again thereby reducing the power demand on the supply system. The necessary switching can be carried out by frequency control. The stator can be fitted with a brake for use under certain circumstances.

Title: Palletising system for rectangular items - has two packing plates used alternately to assemble layers for scraping onto pallet
Inventor: BECKERT ALEXANDER
IPC: B65G57/24
Filed: 1977-04-25
Abstract: The system palletises rectangular items, esp. books delivered at high speed, these being assembled into a layer on a packing plate by means of a stop and then thrust sideways. The plate is then extracted and the layer scraped off onto the pallet below, which is indexed downwards for the height of a layer, after which the plate is moved back into the position for receiving the next layer. The items are thrust by rows on the plate, which is then lowered onto the pallet, and a second plate in a waiting position is brought into the working position, the first plate being moved into the waiting position after discharging its layer. When loading of the pallet is complete, the items are thrust in the opposite direction at right angles to the travel direction, to load the next pallet.

Patent DE-2827615-A1 (DE)
Title: Digital communications link transmissions sync. system - uses several synchronised shift registers in geographically separated units
Inventor: BITZER WOLFGANG DIPL ING
IPC: H04L7/04
Filed: 1978-06-23
Abstract: The transmitter contains a shift register with feedback (11, 15) which sends a bit sequence to the receiver. Here it goes to the output, one input of a modulo-2-adder and through a switch to a second shift register. When the two shift registers produce the same output, the adder output is seen at zero by a detector. A sequence of nulls therefore shows thatthe shift registers are synchronised. Switches now operate to permit data communication synchronised by the shift registers. This process may also be used with scramblers.

Title: Fine droplets prodn. by ultrasonic atomisation - using bipolar resonator attached to HF source of proportions to give droplets in 5 micron range
Inventor: DREWS WOLF-DIETRICH DIPL PHYS
IPC: B06B1/06
Filed: 1978-07-18
Abstract: Ultrasonic atomiser has an a.c. supply applied to a piezoceramic actuator joined to a metallic resonator. The thicknesses of the actuator and resonator (d1,d2), as measured perpendicular to the joint face, are given by the formula d1 = n1 lambda 1/2 and d2 = n2 lambda 2/2 (where lambda 1 and lambda 2 are the sound wavelengths in the two materials at the operating frequency, and n1 and n2 are integers between 1 and 5). The min. width (A) of the unit should be >=5 times the sound wavelength in the material being atomised (lambda F). The liq. is then introduced onto the atomiser as a smooth thin film. The film thickness is 1-2 times the sound wavelength (lambda F) in the liq. Used for producing very fine droplets, esp. for use in blood analysis. The atomiser produces droplets of 1-6 mu from very small amts. of liq. and transmits only a very small amt. of heat into them.

Title: Variable volume rotary piston pump - has cylindrical piston rotating on eccentric of shaft itself capable of limited eccentric rotation in drive shaft
Inventor: HELLMANN HERMANN
IPC: F04C2/344
Filed: 1978-11-25
Abstract: The pump has a cylindrical pump chamber containing a cylindrical piston (10) which is rotatable about its own axis on an eccentric extension (8) of a drive shaft (6). The extension (8) is an eccentric shaft end of a shaft (7) which is itself eccentrically carried in the drive shaft (6). The arrangement permits limited relative rotation between the shafts (7, 6). The eccentricity of the extension (8) relative to the inner shaft (7) may be equal to that of the inner shaft relative to the drive shaft (6). Relative rotation of the inner shaft (7) relative to the drive shaft may be limited by stops whilst a spring tends to move the shaft (7) towards one of the stops.
Patent DE-2852969-A1 (DE)
Inventor: OGAWA TOKUMON
IPC: G04G3/00
Filed: 1978-12-07
Abstract: An electronic watch comprising two, or more than two, quartz vibrator oscillators (1, 2) is provided by means (3c, 7e, 7g, 7f) of electrical screening between the parts influenced by each of the two oscillators, so as to suppress any electromagnetic coupling and thus preclude the frequency-pulling effect due to this coupling. Moreover, the quartz-crystal vibrators (1, 2) are mounted by way of cushions (9, 8) which suppress any transmission of mechanical vibration and eliminate any risk of a frequency-pulling effect due to a possible mechanical coupling. The proposed design applies very advantageously to high-precision electronic watches of the type provided with several quartz-crystal oscillators. <IMAGE>

Title: Intrinsically safe emergency voltage supply - has battery supply switched in over voltage-current regulator and diode preventing reverse flow of mains when emergency supply is active
Inventor: TRETOW JOCHEN ING GRAD
IPC: H02J9/06
Filed: 1979-03-30
Abstract: An emergency voltage supply for a data transmission system steps in when the main supply fails and it is intrinsically safe in operation. The mains supply (1, 2) is connected over a bridge rectifier (3) to a conductor (4) coupled to output via a diode (5), that prevents reverse flow when the emergency supply is active. A charge regulator (8) maintains the condition of two standby batteries (10, 11). If the main supply falls a relay circuit (13) is switched to cut in the battery supply. The voltage is supplied to an output (6, 7) over an intrinsically safe voltage-current regulator (12).
