Title: Energy source for vehicle clock - is operated by variations in air pressure due to movement of vehicle and changes in altitude
Inventor: BEZAK LADISLAV DIPL ING
IPC: G04B5/22
Filed: 1973-12-27
Abstract: The energy source employs an expansion chamber, which is operated by a rise or fall in the air pressure, due to the movement of the vehicle, e.g. an aircraft. The drive system for the clock operates from the expansion chamber, in similar manner to a barometer or altimeter. The expansion chamber is drawn out by an increase in the air pressure and returns back to its original position due to a fall in the air pressure, these movements being transferred to a mechanism which converts them for the operation of the clock spring.

Title: Shell-and-tube heat exchanger - with sector-shaped tube-supporting baffle plates
Inventor: LOEWE GERHARD
IPC: F28F9/22
Filed: 1974-03-04
Abstract: In a heat exchanger consisting of a bundle of tubes (through which a first medium flows) inside a parallel cylindrical housing (through which a second medium flows) the tubes are supported at regular intervals along their length by transverse anchored baffle plates equal in size and whose shape is that of the sector of a circle. Each successive baffle is positioned at an angle of rotation relative to the previous baffle so that the second medium flows through the shell along a spiral path. Each baffle is rotated through the same angle relative to the previous baffle. "Dead space" is eliminated or greatly reduced. The degree of turbulence corresponding to a given velocity is reduced so that lower press. drops and erosion rates are obtd.

Title: Pulverized solid fuel injector - for gasifier has exchangeable wear liners for mixing head, blow tube and burner
Inventor: WALDHOFER REINHARD
IPC: F23D1/00
Filed: 1974-05-30
Abstract: Pulverised solid fuel is introduced into a gasifier with a gas containing oxygen through a mixing head to produce the fuel/oxygen suspension, a blow tube and a burner terminating in the gasifying chamber. Both mixing head blow tube and burner have inner exchangeable wear liners which are interconnected and extend in case of thermal elongation relative to the blow tube and burner into the gasifying chamber. A sliding seal joins burner and blow tube. This reduces the costs for replacing the rapidly wearing inner parts and the downtimes for a gasifier. All walls are designed for up to 30 atm. pressure and offer higher functional safety. The throughput of fuel can easily be changed by using wear liners of another inside diameter.

Title: Flow control valve for liquids - maintains continuous outlet flow and prevents clogging of valve body
Inventor: TACKE ALBERT
IPC: F16K11/04
Filed: 1974-07-25
Abstract: The valve body consists of two co-axial tubes (6) and (7). The outer tube (6) has an inlet (5) and an end cap (3) with an outlet (10) which forms a valve seat.

Title: Ambient atmosphere heat exchanger - has part of compressed super heated vapour removed before condensation for use with cool uncompressed vapour
Inventor: REITH HEINZ-KONRAD
IPC: F25B40/00
Filed: 1975-04-30
Abstract: A system is used for heating up a flowing medium by extraction of heat from the surrounding atmosphere, and it is designed so that the flowing medium is first cooled and then expanded before the cooled vapour is finally compressed and superheated. This ensures that after cooling in a heat exchange mode with the surrounding atmosphere, it is condensed and the condensate liquid is then re-vaporised. The system is constructed so that part of the compressed, superheated vapour is diverted or removed before the condensation process and this diverted vapour is condensed in heat exchange contact with the cooled, uncompressed vapour, before being fed to the evaporator.

Title: Electric shock preventing arrangement for hand tools - uses plug provided with socket inlet to neutral pole
Inventor: WOLFSCHLAEGER JOHANN
IPC: H02H5/12
Filed: 1975-06-10
Abstract: The arrangement protects users of hand tools against shocks caused by inadvertent piercing of hidden electrical wiring, for example when drilling, or hammering fasteners, into walls. A plug (1) is provided with a socket inlet to the neutral pole and an indicator lamp on the live pole so that when correctly inserted to a mains socket the lamp lights. This ensures correct polarity on the plug. A lead (4) connects into the socket inlet and joins it tot he earthing handle (3) on the appliance. If this is a drill further sliding contacts (2) with a lead (6) make additional contact with the spindle. If a live cable is pierced the fault current flows harmlessly to the neutral supply pole instead of to earth through the operator.

Title: Current collector for varia transformer - has heat conducting wiper frame with cooling fins for good heat dissipations
Inventor: HAPPACH ANTON ING GRAD
IPC: H01H1/62
Filed: 1975-10-23
Abstract: The wiper for a varia type transformer achieves good heat dissipation characteristics by an increase in the surface area of its frame.
