IPC: H04B5/00
Filed: 1980-05-24
Abstract: The communication link is intended for motor vehicles, freely moving in a defined district and fitted with appropriate transceivers. The link connects to a stationary control transceiver station. In the district are laid two rectangular loops next to each other. Alternately the loops are laid in a meandering shape such that the loop parts of each loop form rectangles. The conductor portions on the longitudinal sides of the rectangles are supplied in their succession by current flow of opposite direction. The loop portions of the two loops are arranged adjacent each other. Both loops are connected to the stationary control transceiver station via phase stages with specified phase rotation angle of both stages. The motor vehicle is fitted with a vertical directional ferrite aerial, or a horizontally aligned frame aerial.

IPC: B21J9/02
Filed: 1980-12-24
Abstract: In the device for producing pressed pieces, for example screws, by cold deformation, four toggle-joint presses (E) are arranged with angular spacings of 90 DEG  on a ring (D) which rotates about a fixed axle (B). On the axle (B), control cams (1, 8, 14) are arranged, by means of which in each case a toggle-joint linkage (2), articulated to the movable tools (6), of each of the toggle-joint presses (E) is controlled. During a rotation of the ring (D), each toggle-joint press (B) is twice in the closed state and twice in the opened state. A control cam (8) controls the ejection of the finished pressed piece via a roller (9) and an ejector lever (10) which can be pivoted about a pivot axis (11) and actuates an ejector bolt (12) with an ejector (13) which repels the pressed piece from the die-plate (7). By virtue of the four toggle-joint presses present a substantially increased capacity in comparison with known machines of this type can be achieved. <IMAGE>

Title: Valve operating mechanism of a gas lock with a float bell
Inventor: MARUOKA MASAKAZU
IPC: F16T1/30
Filed: 1981-02-26
Abstract: In a gas lock for separating condensate from a steam system or from a compressed air system, the valve operating mechanism has a valve stem (21) extending through a valve guide (20). The valve guide (20) is situated at the lower end of a valve seat cylinder (13). An eye (26), which is fastened to the upper side of a float bell (7) situated in a condensate chamber (5) of the gas lock, and the lower end of the valve stem (21), which points towards the upper side of the float bell (7), are connected to one another in articulated fashion by an actuating lever (25), the lever and the valve stem being connected in the central area of the actuating lever (25), one end of which is articulated on the eye (26) and the other end of which can come to rest occasionally against the valve guide (20). If the buoyancy of the float bell (7) is large, the buoyant force forces the valve stem (21) upwards due to the contact between the lower end of the latter and the upper side of the float bell (7) while the condensate fills the condensate chamber (5), whereas, during the downward movement of the float bell (7), the downforce is multiplied due to the leverage of the actuating lever (25). <IMAGE>

Title: Method for organising air traffic by the introduction of four-dimensionally fixed-position optimum flight paths, taking into account the wind conditions
Inventor: MODLINGER ANDREAS DR ING
IPC: G08G5/00
Filed: 1981-07-08
Abstract: The invention relates to a method for organising air traffic and for methodical guidance of the aircraft which are involved in the traffic and are equipped with autopilots, automatic thrust controllers and on-board computers. In order to achieve an optimum traffic flow, commercial airports have rigid time frames for the allocation of take- off and landing runways. Before a take-off, the airport at which the aircraft will land is requested to define a landing time which can be achieved in optimum conditions. The take-off time and the intended flight path over predetermined waypoints are calculated using an on-board computer with the landing time having been specified, taking into account the weather data which are stored in a data bank and applied to the respective intended flight path, and the flight path and speed at which the aircraft is to fly in the individual phases (sectors) of the flight are specified (predetermined) and possibly corrected by the on-board computer, taking into account the prevailing weather data.

Title: Car roller roof for shielding against the sun
Inventor: BACOKA JOSIP
IPC: B60J11/00
Filed: 1981-08-01
Abstract: The car roller roof for shielding against the sun has a roller support beam which is arranged on a car roof bow and bears two rolled-up sun-shielding tarpaulins held in parallel, and is attached to the car roof bow such that it can be horizontally rotated by means of the vertical connecting spindle. Since the rolled-up sun-shielding tarpaulins, owing to the desired shadow, are wider than the vehicle itself, they must be fastened by support elements in the longitudinal direction of the vehicle for transportation on the car roof. To obtain the sun-shielding position at the parking place, the sun-shielding tarpaulins are rotated out of the vehicle longitudinal direction into the vehicle transverse direction and then one tarpaulin is unrolled towards the front part of the vehicle and the other towards the rear part of the vehicle and secured by a tightener and hooks. The auxiliary bows are used for securing the roller support beam in the longitudinal direction and for maintaining the heat-insulating distance of the tarpaulins from the car roof. The extendable struts support the tarpaulins over the width of the vehicle. The securing of the car roller roof for shielding against the sun to the car roof and also the unrolling and rolling up of the tarpaulins can take place in 1-2 minutes.
