Title: Electronic tachometer for IC engines - has engine ignition pulses applied to monostable flip=flop to produce train of pulses of constant duration and varying frequency
Inventor: BAYA WULF ING GRAD
IPC: G01P3/48
Filed: 1976-08-19
Abstract: The electronic rev. counter for IC engines, consists of a monostable flip flop to which the filtered engine ignition pulses are fed. This produces a train of fixed duration but variable frequency pulses to a suitable display instrument. Ignition pulses from the contact breaker in the engine ignition system are fed to a voltage divider (R4, R1, R2) and filtering circuit containing a zener diode (Z1) and capacitance (C1) the output of which triggers a monostable fixed pulse duration flip flop (2). A train of fixed duration pulses of frequency dependent on the engine speed, is fed to a suitable voltmeter display (3). The shape of the ignition pulses and the operation of the filtering circuit are described at some length.

Title: Free-flowing material filling system - lifts containers against air exhaustion nozzles on way to filling station to accelerate flow of material
Inventor: ZIMMER ALBERT
IPC: B65B1/16
Filed: 1976-10-13
Abstract: The system fills containers, open at the top, with free-flowing material in powdery or granular form. It uses a merry-go-round type automatic filling mechanism. The containers are delivered to a guide track concentric to this mechanism and removed from it, there being a filling hopper above each container compartment in the track. Above these hoppers at the filling station is a stationary loading hopper, preferably with a metering device. On the way to the filling station (24) the containers (40) are lifted so as to seal their mouths against a spring-mounted air exhaustion nozzle in front of the filling hopper outlet. This nozzle has a first opening opposite the container mouth, and a second one surrounding the first to exhaust air from the container before filling takes place via the first one.

Title: Fluid pressurising pump of variable flow resistance - exerts uniform pressure over whole revolution with one displacement part only
Inventor: KACHEL GUSTAV
IPC: F01C1/02
Filed: 1977-01-21

Patent DE-2702422-A1 (DE)
Title: Fuel injector lance, esp. for blast furnace blower - has inclined high speed atomising ducts and radial outlets
Inventor: BERNARD PIERRE JAMES
IPC: C21B7/16
Filed: 1977-01-21
Abstract: To inject fuel into an air blast heater and improve its combustion, the fuel is vapourised into a medium-possibly a mixt. of air and steam, and is injected into a gas flow within the heater at an angle between 60 and 120 degrees to the lengthways direction of the gas flow. The fluid is vapourised by contact with the gaseous medium fed in at a speed at least equal to that of sound, and the vapourised fuel is also injected into a heater flow at the speed of sound. Method overcomes both the difficulties of the accumulation of soot from the long flames of axial injection lances and the uneven distribution of the fuel in the hot air blast, at the high injection speeds necessary in radial lances, ensuring improved combustion and efficiency. The deflection of the injected fuel jet into the gas source of the air blast heater, prevents its striking against the sides and causing damage to the walls of the heater. The press. of the gas and the fuel can be adjusted to give the required distribution and injection press., more efficient combustion is ensured and larger quantities of fuel can be used.

Title: Filling liquids into measuring cylinders - uses principle of communicating vessels, to ensure measuring cylinder filling up to selected level
Inventor: RUDOLF ROLAND DIPL KFM
IPC: A61C19/00
Filed: 1977-03-26
Abstract: Filling method for certain liquids into a measuring cylinder for use in medical espec. dental laboratories. The liquid is moved by a pump (2) from a storage container (1) through a 'U' shaped pipe (3) into a measuring cylinder (4), which is attached to the longer leg (5) connected to the storage container at any selectable height, using a magnetic ledge etc. The height of the measuring cylinder (4) is chosed so that the pipe end of the shorter leg (7) is in line with the height of the marking (8) up to which the measuring cylinder is to be filled. A greater amount of liquid than that to be filled is moved into the measuring cylinder by the pump so that according to the principle of communicating vessels the excess amount of liquid runs back into the storage container.

Title: Mass produced building element - has thrust joint surfaces with flat thrust plate and spacers
Inventor: BORSDORF HEINZ DIPL-ING
IPC: E04B1/24
Filed: 1977-07-25
Abstract: Building elements are mass-produced with suitable thrust connection surfaces, preventing relative displacements and twisting of the surface serrated units under normal pressure. Thrust lamellae made from flat sheet metal plates (2), or similar, are worked into elements with low shear resistance, shaped along the joint surface so as to take over shear connection. They are fitted in connection with spacers so that interfacing elements to be connected lie in a single plane. This facilitates production of statically monolithic structures from prefabricated mass-produced elements, and connection of elements made from different materials.

Title: Fixing for corrugated asbestos-cement roof panels - has metal cylinder passing through holes in overlapping panels to create form fit
Inventor: BECKER ULRICH
IPC: E04D3/365
Filed: 1977-07-30
Abstract: Fixings are designed to provide a strong form fit between overlapping panels. The horizontal component of the roof loading is thus taken by the roof material itself, eliminating need for struts between the purlins to which the panels are fixed. The fixing comprises a sealing cap (16) of elastic material, which bears on the surface of the roof panel (13), and has integral cylindrical section (17) through which the fixing bolt (15) passes. The elastic cylinder (17) is enclosed in a stiff metal cylinder (18), the transverse shear strength of which transmits loadings in the plane of the roof panels.

Title: Radio broadcasting system divided into regions - has specified transmitters sending information identifying regional transmitters for retention in receiver store for tuning
Inventor: HENZE WERNER
IPC: H04H20/28
Filed: 1977-11-09
Abstract: The radio broadcasting system includes regions in which transmissions from several transmitters can be received. At least one transmitter transmits data identifying those transmitters in the region of the one transmitter which can be received in the local region. A receiver for use with the system stores the transmitted data for tuning purposes. The stored data comprises a code describing the transmitter's frequency, the board casting station and the programme. This code is entered into a store by operating a programming button. The store's receipt of the entered data is acknowledged by an indicator lamp. The advantage lies in the simple way in which the store is programmed and in tis relatively small capacity.

Title: Line protecting circuit breaker with rotary handles - has actuating mechanism transmitting handle turning to toggle during first rotation phase
Inventor: BARBARA LOUIS
IPC: H01H9/22
Filed: 1978-01-02
Abstract: The circuit breaker has a tripping element and a swivelling toggle for automatic or manual actuation of a contact driving toggle lever mechanism. On manual operation a rotary handle transmits its torque to the toggle, while the toggle swivel is transmitted to the handle at automatic operation. The actuating mechanism (14) transmits forcibly the handle (16) rotation during a first phase from the closing to the breaking position. During a second phase of the handle rotation beyond the breaking position into a locking position, the coupling between the handle and toggle is interrupted, in order to enable the handle rotation towards the locking position when the toggle is in the breaking position. If the contacts should be stuck by arcing the rotation into the locking position is prevented.

Title: Strip or belt roll regulator - has roll rotated about vertical axis in response to edge scanner
Inventor: SCHICK GUENTHER DR ING
IPC: B65G39/16
Filed: 1978-09-04
Abstract: The strip or belt travel regulator has two parallel rollers held in a frame which can be pivoted about an axis normal to the axes of the rollers. The rotating angle is determined by the displacement of strip edge which is scanned.
