Title: DC motor with increased power output - uses increasing effective length of rotor by sawtooth shape
Inventor: LERCHE ERNST
IPC: H02K1/06
Filed: 1974-12-19
Abstract: The direct current motor has a rotor (1) whose diameter increases and decreases along its axial extension. The stator (3) is constructed in complementary manner to the rotor. The increase and decrease in diameter may be sinusoidal or of sawtooth shape. The advantage lies in increasing the motor power for a given weight by increasing the effective length of the rotor, based on the fact that the power of a motor is determined mainly by the effective length of the rotor.

Title: Heating Cowper stoves on blast furnaces - where gas and air is preheated in recuperator fed with re-heated flue gas
IPC: C21B9/14
Filed: 1975-05-03
Abstract: Process for heating Cowper stoves on blast furnaces, comprises preheating the heating-gas and the combustion-air for the burners in the stoves, with the aid of the flue gas in a recuperator.

Title: Eccentric shaft for peristaltic pump - has eccentrically located discs stacked on drive shaft to operate activator plates compressing tube
Inventor: ECKLI PAUL
IPC: F04B43/08
Filed: 1975-09-27
Abstract: Eccentric discs located on a drive shaft provide the required oscillating motion for a peristaltic pump used in infusion processes and or delivery of a material volume of fluid. Fluid in a tube is pumped at very low rates by progressive compression of the tube by a stack of actuator plates (10) moved in cyclic fashion. Each plate has an elongated slot that receives a circular disc (5). Each disc has bore that is eccentrically located relative to the periphery. Each disch is tied to adjacent ones by a number of dowel pins. All discs are located on a drive shaft (4) supported in bearings (7) and motor driven (15) over a gear train (17, 18, 19). The discs transmit vertical motion to the actuator plates to force the fluid through the tube.

Patent DE-2614487-A1 (DE)
Title: Circuit for radiation detector with timing stage - which gives alarm when preset pulse rate is exceeded
Inventor: RUSCH HANS-JOACHIM
IPC: G01J1/42
Filed: 1976-04-03
Abstract: The circuit arrangement is intended for use in conjunction with gas discharge detectors for recognising and evaluating radioactive or ultraviolet radiation by conversion of the radiation into a pulse sequence. The output of the detector element is connected to a digital evaluation circuit comprising a timing circuit, the response sensitivity of this timing circuit is designed to a predetermined pulse rate per time and, only when this pulse rate is exceeded, does it trigger an alarm and/or indicator device. Used partic. for fire-monitoring installations and flame announcers. The digital evaluation circuit is used instead of the more conventional integration circuit, in order to eliminate the effect of random pulse rates arising from background radiation of relatively low level. This results in a much more rapid response than that obtd. with the delay of the integrating circuit.
Patent DE-2623542-A1 (DE)
Title: Fire protection system based on electric induction - uses current generated by rotating handle to open windows
Inventor: VETTER HARALD ING GRAD
IPC: A62C2/06
Filed: 1976-05-26
Abstract: The fire protection system consists of a number of generators which can be operated by manually rotating the handle. The generators are placed in convenient positions throughout the building in which the fire protection system is installed. The generators are connected by wires to solenoids which open the windows when energised by the current generated by turning the handle. The solenoids may also actuate a spring loaded cylinder, which opens the domed roof light. By rapid opening of the windows any smoke or heat can escape before a fire is started.

Title: Impeller blades of fan assisted heater - have ends bend backwards or forwards to give more even air distribution
Inventor: ZINSSER RUDOLF DR ING
IPC: F04D29/28
Filed: 1976-07-20
Abstract: A fan disc (1) has a central hub which is mounted on the shaft extension of an electric motor (3). The disc carries axially projecting fan blades (2) on both sides in a circle round the motor. At their outer ends the blaes are bent along a fold (4) to make a circumferentially projecting corner piece (21). The bend can be either forwards in the direction of rotation or backwards against the direction of rotation. When the fan rotates these corner pieces propel air from the disc towards the free ends of the blades to give a more even air flow over the whole length of the blades. This gives a more uniform air distribution through the heater grid downstream of the fan.

The coil of material is secured between a pair of flanges (11, 17) on the mandrel (2), the pull rod (12) being coupled to one of them (17). The other flange (11) acts as an abutment, absorbing the clamping force exerted by the rod on the first one. There can be a clamping plate (16) at the free end (13) of the rod, against which the outside of the first flange bears. The second one can be spring-mounted. On the outside of the second flange (11) there can be a supporting disc (4) located axially on the reel shaft (1), and with apertures for spring guide pins (8) on the second flange.

Title: Connection between ends of cable reinforced conveyor belt - has rubber filler replacing partially removed belt material over steel reinforcement
Inventor: STUDENSKI WALTER
IPC: F16G3/10
Filed: 1976-09-30
Abstract: The connection is between the ends of a conveyor belt having internal steel cable reinforcement. The belt cover material is removed to expose the end portions (5, 6) of the cable and these portions are inter-engaged. At each side of the belt, a part length of the cover material (7, 11; 8, 12) is removed down to about half of its thickness. The stepped recess formed in this way at each side of the belt is filled with a corresponding shaped filler section of rubber which overlaps the parent material of the belt where latter material is partially removed. Special rubber inserts may be provided between the filler and the belt parent material to accommodate any incompatibility.

Title: Closed loop model car racing track - has accelerator station with rotating impulse wheels raised and lowered by manual control (BR 16.11.77)
Inventor: HAMANO NUBUO
IPC: A63H18/02
Filed: 1976-10-26
Abstract: A closed loop race track for model cars is provided with several lanes which are located side by side. A fixed accelerator station is used to transmit momentum to the cars as they move past the accelerator location. The accelerator includes a rotating sprocket wheel for each car. The radial arms on these wheels are long and flexible and can be raised and lowered with a manual control. As they engage the top of the passing cars, they propel them forwards. The amount of propulsion transmitted to the cars is proportional to the closeness of the radial arms to the contact area on the car.

Title: Transferring bulk goods from one container to another - using air-lock chamber and pressure equalisation procedures to assist transfer operation
Inventor: KANICS ANDRAS DIPL ING
IPC: B65G53/46
Filed: 1976-12-20
Abstract: The flow of bulk goods is guided into the inlet opening of the air lock chamber and allowed to spread within an enclosed support surface in accordance with the pouring or flow angle applied. During this process the outlet opening of the lock chamber remains sealed tight both as regards pressure and bulk goods. The pressure inside the lock chamber is then adjusted to bring it in line with that existing inside the receiving container and after a pre-determined volume of bulk goods have been moved into the lock chamber it's inlet opening is locked by its closure element. A further pressure equalisation operation is then carried out followed by the transfer of the bulk goods inside the air lock chamber through the outlet opening into the receiving container.
