Title: Contact guide for withdrawable switchgear - with protecting flaps closing under gravity and also increasing creepage path (BR 15.2.77)
Inventor: KOLL WILLI ING GRAD
IPC: H02B11/24
Filed: 1975-11-10
Abstract: The tubular guides pass through a dividing wall (1) in a switchgear installation employing withdrawable units. The guides (2) have latches (4) which hold the inner flap (3) in position when the switch is withdrawn and thus prevent inadvertent opening. To allow the external flap (6) to close under gravity, it is hinged on extensions of the pins (5) which act as hinges for the inner flap (3). The flaps can however move independently. The outer flap is also cap shaped, overlapping the of the tube, and thus increases the creepage path from the fixed live contacts of the installation.

Title: Valve arrangement for automatic sampler - with fixed metering proportions of diluent added to sample
Inventor: PRONI OSCAR
IPC: G01N1/38
Filed: 1976-03-11
Abstract: Valve arrangement for automatic sampler with diluent metering and mixing as in 2500527 has the sampling and diluent pistons operated by rotating eccentric drive which is coupled to the main valve by means of a follower in a groove on a rotating cylinder which actuates a rotatable shaft on the valve. This causes the valve to move between two posns. depending on the posn. of the rotating piston drive. In its first posn. it serves to connect the diluent chamber with the diluent outlet, while in its second posn. it connects the diluent outlet with the sample inlet and outlet lines. The cam follower has two curved profiles on it and the eccentric cam runs against these to push the valve from one posn. to the other. For use with accurate metering of samples where it is of advantage to dilute these accurately. The system carries out this function automatically for blood samples and other liquids. The system in the parent patent has the problem that the piston coupling used to operate the control valve is expensive and difficult to operate in connection with the rotating arm. The modified system is simpler, cheaper and more effective.

Title: Wind vane turning about vertical axis for decoration and advertising - has blades resiliently mounted on rods extending horizontally from central hub
Inventor: MEINERS ANTON
IPC: G09F7/22
Filed: 1976-10-16
Abstract: By replacing the freely moving blades with blade rods (3) and blades (9) suspended on the rods with resilient connections (8) the wind pressure swings the blades around their rods and generates in the resilient connections certain counters tresses. These counters tresses retard the swinging blades silently and smoothly and thus limit their play. The vane hub has fixed horizontally on it a holder which holds the blade rod at right angles to the holder and inclined to the ground plane. When there is no wind, the blade plane is tangential to the vane and perpendicular to the ground plane.

Title: Discs for restoring tennis racket strings tension - are inserted between strings at their points of intersection
Inventor: NIGGE WERNER DR
IPC: A63B51/11
Filed: 1976-10-16
Abstract: The strings of tennis rackets made from catgut tend to lose their initial tension after a relatively short period of use. In order to restore the original tension it is proposed to use small discs or rectangles of plastic of between 4 and 10 mm in dia. and 2 to 4 mm thick. These discs are inserted between the strings at their intersection points. It is sufficient to fit the discs at the intersection points of only the lower cross strings when the strings first lose their tension. When a further loss of tension occurs more discs can be fitted at the intersection points of the upper cross strings.

Title: Gas pressure and temp. monitor and switchgear - has temp. related pressure characteristic held in ROM for comparison
Inventor: KUGLER ROBERT DR TECHN
IPC: G05D16/20
Filed: 1977-03-29
Abstract: The gas pressure/temperature monitor for gas-quenched electrical switchgear consists of a temperature sensor (1) which monitors the temperature of the quenching medium, e.g. Sulphur Hexachloride. The signal is converted to digital form (5) as an address for a read-only-memory (6) in which is stored the density characteristic for the gas. The temperature-related pressure is compared with the actual value of the gas pressure as sensed by a pressure gauge (7). This signal is digitised and fed to an 8-bit comparator (10). If the actual value falls below the desired value, then a relay is energised (11) to operate an alrm. In order to provide an additional signal when the acutal value approaches a critical value, a second comparator is used (12) which is fed from the ROM via an adder (13) whose second input is fed with an additional set point value.

Title: Commutation control for inverter supplying sync. machine - uses sub-transient voltage as reference for instant of commutation
Inventor: NEUPAUER HELMUT DIPL ING DR
IPC: H02M5/27
Filed: 1977-08-08
Abstract: The application is to the control of commutation in an inverter feeding a synchronous machine. The subtransient voltage (e") is employed as the control signal as, during transient conditions, it is virtually an invariable quantity. By its use the triggering of the commutation circuits is made more accurate, thus the operating range of the inverter is extended beyond what is permissible with conventional commutation signals. In a practical application the subtransient voltage is evaluated in a computer from the synchronous machine equations. Measurements of voltage and current, and also field voltage position, are combined with the known machine constants in calculation of the required quantities.
