Title: Automatic staircase window opener - has heat sensor with electric controller and electromagnet operated cylinder actuator
Inventor: KUHN HANS
IPC: E05F1/00
Filed: 1974-12-30
Abstract: The arrangement consists of a heat sensor on each landing, an electric controller transforming the sensor signals into operation signals and a cylindrical spring loaded, electromagnet-controlled actuator. While the window is in closed position a spring is kept compressed under the influence of a disc and, at the same time the window is kept closed by an electromagnet. When the signal from the controller de-energises the magnet, the window springs open due to pressure from a spring exerted onto the disc, and a rod moves out from the cylinder, but is checked in its s movement by another spring. The arrangement avoids the window oscillating before arriving at its open position.

This effectively alters the inclination of the seat as well as the effective height. The slider (12) is operated by an eccentric linkage (16, 19) whose end is attached to a threaded spindle (20) and a hand operated screw wheel. By turning the screw wheel the linkage pushes the slider up and down and acts as a self locking adjustment.

Patent DE-2525961-A1 (DE)
Title: Protective bottle cover surround - consists of container with flexible recesses and collapsible sections next to inwardly projecting grooves
Inventor: SCHMITZ ANTON
IPC: B65D77/04
Filed: 1975-06-11
Abstract: The cover protects individual bottles against breakages during transportation and esp. during emptying. It consists of a container (1) with a removable overlapping lid (2) of tin plate. The upper section of the container jacket has recesses (3), positioned on the same plane. The internal diameter (4) of the recesses is smaller than the external bottle diameter (5) resulting from the largest minus tolerance. The circular container jacket may change to a polygon, when the cylindrical section of the bottle (6) is inserted into and moved out of the container through the recesses. During the bottle movement, the recesses may be altered in shape (9) to adjust the bottle size. The container has inwardly projecting grooves (11), which serve as collapsible sections during impact. The internal diameter of the grooves is slightly larger than the largest possible bottle diameter.
Patent DE-2527798-A1 (DE)
Title: Method of improving output from dipole aerial - includes connecting elements in series with phasing adjustment in coupling leads
Inventor: VORMANN HANS
IPC: H01Q21/06
Filed: 1975-06-21
Abstract: To improve the output of dipole aerial arrays their elements are connected in series instead of in parallel. Increases in signal strength of 3dB per series pair are claimed. For successful series operation the dipoles have to be joined by a matching connection which changes the phase of the signal from the first dipole by 180 deg before connecting it to the second. In this way the voltages are cumulatively added. The increased basic aerial impedance due to the series connection can be compensated for by the inclusion of an impedance converter in the signal circuit.

Title: Single port fluid flow control - regulates flow rate in infusion system using variable frequency magnetic valve
Inventor: GRIPP STEPHAN
IPC: G05D7/06
Filed: 1975-06-27
Abstract: An arrangement for controlling the flow rate of single port fluid systems, is used esp. for infusion systems for blood, saline soln. etc. It uses the pressure reduction in the head of liquid for control of the system air supply. Improved stability and accuracy are achieved with small cost using minimum moving parts. Current infusion containers and instruments are used, thus avoiding additional sterilisation procedures. An air container (3) is connected into the system or not connected by an electronically operated magnetic valve (2). Operation of the valve is dependent on the ambient pressure (4) or on the system airway (5) pressure reduction. The valve is driven from a variable frequency generator (1) variation of the frequency alters the average flow rate.

Title: Squirrel cage rotors for electric motors - made by low pressure die casting using vibration to obtain sound castings
Inventor: MEISER JOSEF
IPC: B22D18/04
Filed: 1975-12-20
Abstract: Squirrel-cage rotors are made for alternating electric machines by the low-pressure casting process, so both the grooves and the short-circuit rings are accurately cast. The novelty is that a preheated stack of laminations is inserted between an upper and a lower die in a press, and a mandrel is fed through the vertical hole in the stack; the lower die has an ingate above a vertical standpipe fed with molten metal from a crucible located below the press in an air-tight holding furnace. A pressurised gas is fed into the crucible to drive the metal up the standpipe and into the dies, while the stack of laminations is subjected to the action of a vibrator which improves the soundness of the casting. Relatively long rotors can be cast with a narrow grooves without air being entrapped in the groovs during casting. The air can cause piping or porosity, resulting in scrap castings.

Title: Tube cracking furnace in reactor concrete pressure vessel - has expansion joints and top plate cooling to minimise thermal stresses
Inventor: BARCHEWITZ EKKEHARD DIPL ING
IPC: G21D9/00
Filed: 1976-04-06
Abstract: A tube cracking furnace comprises tubes suspended from a supporting plate and surrounded by a cylindrical wall. The furnace is mounted in a pod in the concrete pressure vessel wall and the primary coolant gas from the nuclear reactor enters and leaves through coaxial ducts and also passes through the annular space between the cylindrical wall and the pod liner. The cylindrical wall is composed of several, pref. 3, internally insulated sections, with sliding joints forming seals between them. On the hot gas side of the support plate for the tubes, which constitutes the top closure for the furnace, there is a space through which cold-side coolant gas passes, thus keeping the support plate relatively cool. The support plate is connected by a thermosleeve to the pod liner so that it seals the space above from the furnace below. Useful for generation of H2 from a mixture of CH4 and H2O, utilising the heat from a high temperature reactor before the coolant gas passes to a steam generator. Components subjected to high temp. have diminished thermal loading and replacement of all components of the furnace including the catalyst is relatively easy to carry out. Problems caused by thermal expansion are kept to a min.

Title: Universal movable socket outlet - moves on rail, eliminating long cables lying on floor
Inventor: KOETHER PAUL JUERGEN
IPC: H01R25/14
Filed: 1976-04-08
Abstract: The socket-outlet is intended to deliver current for all types of electric and electronic equipment. The socket-outlet can slide on an aluminium rail mounted on the wall, and is currentless owing to the special contact arrangement until the plug is inserted. Owing to the movability of the socket, safety is improved owing to the possible of omission of extension cables and adaptors, thus eliminating cables lying on the floor. The socket-outlet can be used for all types of current, direct alternating, or mains power.

Title: Pin diode phase shifter for waveguides - has low diode input capacitance for more rapid phase changing
Inventor: HAMILTON COLIN DR
IPC: H01P1/185
Filed: 1976-04-29
Abstract: The PIN diode phase-shifter for waveguides provides for shorter switching times for the diode control signals in order to obtain more rapid phase changes. This is achieved by reducing the input capacitance of the diode connections. A rectangular waveguide is fitted with a T schebyschev transformer in the form of a ridge waveguide electrically connected to the outer guide. The PIN diode heat sink is in direct contact with the transformer and at zero potential. The diode bias is connected to the inner conductor of a coaxial tube. H.F. isolation between the diode and the signal source is obtained by 1/4 wavelength cylinders, with 1/4 wavelength spacing, placed in the coaxial lead.
