Abstract: The invention relates to a parachute (Survivial Air Guard), preferably applicable in an extreme life-threatening emergency situation. The parachute is particularly embodied as a round parachute and comprises a canopy which is connected to the parachute harness by means of several rigging lines. According to the invention, a parachute which opens quicker than conventional parachutes on usage in emergency situations may be achieved, whereby the canopy is provided with an unfurling and stablizing device for rapid unfurling and preferably stabilizing. The device is preferably fixed to the parachute, preferably within the parachute canopy, and preferably comprises a rapidly-inflating inflation system, preferably with gas generators, preferably airbag systems. In a further embodiment of the invention the parachute is integrated in a survival case.

Abstract: An encapsulated medium-voltage electrical load switching apparatus has four, three-position rotary switches, supported by pairs of opposing insulated half-shells, two-over-two in parallel alignment within a gas-filled sealed shut shell housing.The housing front and back have dome-shaped protrusions to maintain the seal against fluctuations in gas pressure. Bushings in the floor and ceiling of the housing, aligned with the switch face plane, provide gastight connections between the switches and external cables, enclosed fuses and transformer terminals. Switch control is provided by drives mounted on a plate at the front of the housing exterior which operate actuator arms that extend in a gastight way through the housing front and manipulate selector shafts that connect to set the switches into closed-circuited, open-circuited and grounded positions.

Abstract: A flowable concrete mixture which possesses high strength and which provides facile placement of the mixture in structural forms composed of cement glue and aggregates, the viscosity of the cement glue and volume weight of the aggregates being adjusted so that the aggregates are suspended in the cement glue and remain suspended until the cement glue hardens.
