Title: Straight-tooth bevel gear grinding machine - has disc sliding axially to grind both tooth flanks
Inventor: KEDRINSKY WASILY NIKOLAEWITSCH
IPC: B23F5/08
Filed: 1973-08-22

Title: Emergency core cooling for light water reactor - is fed preferentially to higher pressure region of vessel
Inventor: KAFKA PETER DR TECHN
IPC: G21C15/18
Filed: 1974-01-02
Abstract: A method of feeding cooling water directly into the reactor pressure vessel of a light water reactor consists of feeding the water into one of two separate zones, divided according to their different pressures; various, already existing and known partial systems can be connected by pipes leading into the reactor vessel. Used in particular for the emergency core cooling system of a ligh water reactor; also for the normal cooling during shut-down. The automatic arrangement ensures that the emergency cooling water is always supplied to the higher pressure region of the reactor core or pressure vessel, which can vary according to the particular position of the fault. From this higher pressure region circulation to the lower pressure region automatically takes place. Thus, the cooling water is preferentially supplied to the required portion of the core or vessel. Direct flow from the infeed point to the point of leakage is avoided.

Patent DE-2402751-A1 (DE)
Title: Automatic lighting switch for vehicles - has light sensitive shielded cell to complete the lighting circuit
Inventor: SALEM HAMED
IPC: B60Q1/14
Filed: 1974-01-21
Abstract: A light meter is fitted to the vehicle in such a position as to be unaffected by the lights of approaching traffic. The indicator needle is able to close a contact when in the 'dark' position to complete the vehicle lighting circuit, and open the lighting circuit when in the 'bright' position. The light meter is only operative when the vehicle's engine is running. The arrangement takes account of a gradual worsening of visilibity which tends to deceive the human eye.
Patent DE-2405377-A1 (DE)
Title: Chip adhesive applicator unit - has eddy chambers in spinning rotor to prevent chip/adhesive build-up
Inventor: VOELSKOW PETER
IPC: B27N1/02
Filed: 1974-02-05
Abstract: The construction of an adhesive applicator, for use with chips to give a bonded chipboard includes eddy chambers and outlet slits connected by channels, to the hollow shaft of the rotor. The system gives a whirling eddy effect to the chips and the adhesive coating them to give s simpler operation and a thorough coating of the chips with the adhesive bonding agent, without leaving any deposit in the application chamber which reduces cleaning. The rotor spins at 20-60 m/sec at its periphery so that the U-shaped eddy chambers generate secondary eddy effects. As the chips pass through the application chamber, they are subjected to a droplet spray of adhesive from the slits, giving them their coating. The secondary eddies ensure that no adhesive or chip material is retained in the chamber, that the centrifugal effect coats the chips with the adhesive and a clean chamber is maintained which does not require maintenance and the removal of residual matter.

Title: Variable effect sun visor - with graded transparency and vertical adjustment in frontof driver
Inventor: MEYERMANN ERWIN
IPC: B60J3/02
Filed: 1974-10-19
Abstract: The sun visor has a padded housing mounted on conventional swivel bearings at the top edge of the windscreen. Special tinted plastic screens can be swung down from the back of the visor to protect the driver from glare. The screens are tinted in a reducing amount down the length of the plastic. This is achieved by a gradual reduction in the screen thickness down the width of the material. The driver can adjust the vertical setting of the screen so that he can choose the amount of glare protection w.r.t. the illumination. Also the more distant objects on the road, e.g. car headlights, are screened more that are nearer objects, such as road markings.
