Title: Pebble bed reactor control system - has all power regulating rods located above fuel bed
Inventor: TEUCHERT EBERHARD DR
IPC: G21C7/08
Filed: 1973-10-26
Abstract: A power regulating and shutdown appts. for pebble-bed reactors contng. fuel and/or breeder elements and having a graphite reflector comprises: absorber rods (or the like) which can be introduced into the pebble-bed to shut down the reactor; and regulator rods, or pref. plates, which have their operating range solely in the void above the bed and in the part of the side reflector above the bed. Pref., the shutdown rods also move within this limited range. Esp. for use in larger reactors in the range 300 MW (electrical) upwards. No resistance forces caused by entry of regulator rods into the bed need to be overcome. The travel of these rods is reduced, and consequently the rod operating equipment is simpler. There are no local power and temp. peaks in the core. The reduction in neutron flux above the bed causes a change in flux shape, increasing the absorbing action of the fusion prods. within the core, and thereby raising the effectiveness of the absorber rods by 20-40%.

Title: Slide switch for printed circuit board - has contact slider actuated against resetting spring force and is made of sheet metal profile
Inventor: LEITZ EBERHARDT
IPC: H01H15/10
Filed: 1973-11-06
Abstract: The slide switch has a contact slider, actuatable against a force of a resetting spring, made of flat profile carrying contact springs, which make contact with stationary contact elements in the switch housing. The contact slider has a cylindrical extension forming an axis for an insertable rotary sleeve. The extension has a flange, engaging in a guide slot when the switch housing is secured on a printed circuit board. The cylindrical extension has several diametral switching cams, over which slides the upper pressure surfaces of the contact slider, when the rotary sleeve is actuated into rotation. Thus the rotary motion is converted into a stroke motion of te contact slider. The contact slider width matches the opening width of the hollow cylinder.

Patent DE-2363859-A1 (DE)
Title: Cooling process for IC engines - non-combustible volatile cooling fluid is injected into combustion chamber
Inventor: ORTH EWALD
IPC: F02B47/02
Filed: 1973-12-21
Abstract: The cooling process reduces fuel consumption as well as reducing air pollution from the exhaust. After the combustion stage a non-combustible, volatile fluid is injected directly into the combustion chamber. The fluid duly evaporates and cools the ignited mixture and the inner part of the chamber. The additional pressure of gas produced by the evaporated fluid provides extra energy. Advantageously, the fluid cools the exhaust gas in such a manner that it is condensed again and used for a further cooling process. The fluid can bind polluting elements in the exhaust gas while being non-corrosive and lubricant itself.
Patent DE-2365770-A1 (DE)
Title: Thin tubular film e.g. for sausage skins - based on collagen fibre and an amino resin

Title: Accumulator with common filler and expansion chamber for cells - has communicating tube resisting gas pressure build up and preventing link between cells
Inventor: PERKAMS WILHELM
IPC: H01M50/627
Filed: 1974-01-22
Abstract: Accumulator with common filler and expansion chamber for the electrolyte liquid of the individual cells. The object is to facilitate the addition of the correct amount of electrolyte, the check and replenishment of distilled water and to prevent the leakage of electrolyte when the accumulator is tipped over. The feed of the liquid from the expansion chamber is via a communicating tube whose column of liquid is higher than the liquid column formed in the overflow tube. This produces a resistance to the pressure build up of gas in the cell preventing a link between the individual cells. The inlet end of the tube is in the expansion chamber and the outlet end in the allotted cell chamber.

Title: Hinged cover plate for petrol filler nozzle - is unlocked by electromagnet from inside of car
Inventor: ERBE HANS
IPC: B60K15/05
Filed: 1975-07-24
Abstract: The petrol filler nozzle on a vehicle is covered by a hinged spring loaded lid plate (8). When the lid (8) is pressed into its closed position, an undercut taper pin (6) on the inside of the free lid end, engages in a sliding lock plate (2). The slider plate (2) is held in a locking position by a compression spring (10). To unlock the cover lid (8), an electro-magnet, adjacent to the slider plate, can be operated by a switch on the instrument panel. This retracts the slider plate against the spring pressure and so frees the tapered lock pin (6). In case of a power failure, the lid (8) can be unlocked manually from the vehicle boot.
