Patent DE-2353448-A1 (DE)
Title: Motor vehicle fuel tank - has separator chamber in filler pipe to assist air escape from tank
Inventor: GEBLER EUGEN
IPC: B60K15/04
Filed: 1973-10-25
Abstract: The tank is particularly for use on private cars, having a filler pipe of length at least sufficient to accommodate the spout of a fuel pump with automatic valve. A separator chamber is provided in the filler pipe to facilitate air escape from the tank. The chamber can be formed by a section of the pipe pressed flat, with the edge uppermost. The pipe can ascend at an angle where it joins the chamber, towards the filler opening. A sensor in the top of the fuel tank, which may be mechanically or electrically operative, provides a signal to cut off the supply when the tank is full.

Title: Crankshaft for small electric motors on razors - has basic shaft, crankshaft oin and connecting element that also carries motor fan
Inventor: STEMME WALTER
IPC: F16C3/12
Filed: 1973-11-19
Abstract: The end of the basic shaft holds the rotor. The other end has a circular cross section with 'U' or 'V' shaped notch cut along it. The crankshaft pin fits in this recess and is therefore off centre in the connecting hub of the motor fan. The included angle of the notch is between 60 deg. and 120 deg. typically between 80 deg. and 100 deg. There are two parallel boreholes in the fan hub that overlap for part of their circumference. One has the same cross section as the shaft, the other has the same cross section as the pin. The boreholes are made from opposite ends of the hub and have closed ends. The electric razor motor is controlled by a hand operated push rod and/or at least one angle lever.

Title: Decoupling mechanism for toy aeroplane propeller - unlatches claw coupling when motor stops to reduce air resistance
Inventor: WESSELS MICHAEL DIPL ING
IPC: A63H27/30
Filed: 1973-11-30
Abstract: Toy aeroplane propeller idling mechanism reduces the flight resistance after the motor has run out during flight. The propeller is driven via a claw coupling in frictional connection with the motor shaft, and after the motor stops is moved by air resistance on it and its hub and its own wt. owing to the angle of incidence of the motor shaft, is moved a few mm. against the direction of flight and unlatched, disconnecting it from the motor shaft. Preferably, the force on the propeller blades is kept small by use of axial needle bearings in the hub, also reducing the residual resistance of the propeller due to the components acting against the direction of flight.

Title: Infra-red thermal image system - uses mechanical scanning of scene and detector and light source arrangement
Inventor: SCHUETZ KLAUS DR
IPC: H04N3/09
Filed: 1974-01-11
Abstract: The infrared thermal radiation is received by an objective and converted to visible radiation, which is superimposed on the scene image of an image amplifier. A rotary receiver head receives the thermal targest and emits the optical information of the visible radiation thus produced. The optical information is passed to the image amplifier by means of a fixed optical fibre line. The fixed mounting of the fibre line supports the abutment for the rotary receiver head. An auto-collimation mirror is arranged in front of the detector unit. The infrared objective and the optics of the fibre line are accommodated in the housing.

Title: Streamlining system for semitrailers - is curved shield hinged to cab roof and covering gap between cab and trailer
Inventor: MONSLER KLAUS DR ING
IPC: B62D35/00
Filed: 1974-12-23
Abstract: The shield is designed to reduce wind resistance especially in the case where the semi trailer is covered by a tarpaulin. The shield may be constructed of a light metal or reinforced plastic and suitably curved in respect to the direction of travel to decrease the wind resistance, the curvature contributing to the shields mechanical rigidity. The shield is preferably mounted on the tractor cab roof in such a manner as to be adjustable for load height and able to be folded back when not required. The shield produces a more streamlined profile presenting less wind resistance and drag by reducing turbulence in the gap between tractor and trailer.

Title: Vacuum packaging machine for powdered materials - operates at high output without powder being entrained in sealed region
Inventor: SNOEREN HENRIK
IPC: B65B31/02
Filed: 1975-05-02
Abstract: The vacuum packaging unit for powdered materials operates at high outputs without the danger of the powder becoming entrained in the sealed region and reducing the effectiveness of the seal. A controllable throttle valve (30) is interposed in the line between the vacuum chamber and the vacuum source, whereby the valve's passageway is small at the beginning of the evacuation process but increases in size as the evacuation progresses. This is achieved by a valve element (35) coupled to a control membrane (37) and steplessly varies the passageway cross-section. The membrane is loaded on one side by vacuum chamber pressure and on the other by atmospheric pressure.

Title: Concentrating lens for solar energy collector - has mathematically determined side shape to achieve uniform energy density on absorber
Inventor: KLEINWAECHTER JOHANN PROF DR I
IPC: F24S23/70
Filed: 1976-02-25
Abstract: Solar radiation falls on an internally reflecting lens which concentrates the rays onto the absorber surface. The lens receives parallel rays (3) some of which travel straight through it to fall directly on the absorber surface (1) beneath the lens. Other rays strike the internally silvered sides (2) of the lens and are reflected (4) to reach the absorber surface at an angle and combine with the direct rays. The shape of the sides (2) of the lens is mathematically determined to reflect the rays in such a way that the resulting concentration of energy is uniform over the whole absorber surface. The determination of the equation of this shape is based on treatment of the sun as an area source of uniform brightness.
