Title: Escalator
Inventor: LACHNER HANS
IPC: B66B23/12
Filed: 1987-09-05
Abstract: The invention concerns an escalator or moving pavement with successive treads (1) whose tread surfaces (2) are held in a horizontal plane by guide rails (14), and are driven by an articulated chain (6) guided in a track (5), that are connected to the individual steps by connecting elements. In order to simplify the construction of such an escalator by reducing the number of tracks, the invention proposes that the links (4) of the chain (6) be connected together in an articulated manner in a compression and extension-resistant manner, and be guided closely on all sides in the chain track (5), and that the connecting elements each have a swivelling axle (3) held in position by the chain (6) and running horizontally and transversely with respect to the longitudinal direction of the chain, on which the corresponding tread (1); is mounted pivotably with a further guide rail (14) being allocated to the treads (1), in which rail a guide piece (13) of each tread (1), which is positioned at a distance from the horizontal swivelling axle (3), is guided. <IMAGE>

Title: Double-storey parking area
Inventor: QUINTING FRIEDHELM
IPC: E04H6/06
Filed: 1987-10-01
Abstract: Known double-storey parking areas with two raisable and lowerable platforms and a pit for receiving the lower platform require either a deep pit or exhibit a small distance between the two platforms, which makes walking difficult. The novel double-storey parking area is to permit a shallow depth of the pit while, at the same time, making it possible to walk comfortably on the lower platform. The novel double-storey parking area is characterised by an additional raising apparatus (53) which permits an increase in the raising height  DELTA H of the upper platform (3) with respect to the raising height  DELTA h of the lower platform (2). The novel double-storey parking area can be used for anything from an individual parking area for two motor vehicles right up to large-scale parking areas for a multiplicity of motor vehicles. <IMAGE>

Title: Electrical switching element for drives
Inventor: FREI WALTER
IPC: H05K1/11
Filed: 1987-11-11
Abstract: For drives having electrical switching elements, it is proposed that, instead of cable harnesses with individual contact (7) being made, to change to a use for printed circuit boards (6) which are designed for the direct switching currents of the electrical switching elements (9) arising, consist of flexible plastic material and have connecting leads (8) arranged parallel alongside one another. In this case, the connection geometry of the collars and contacts (5, 7) is intended to be moved to a connecting plug board (3) and the various electrical switching elements (9) so that it is not possible for any incorrect connections to occur. Rapid and reliable installation, and permanent connection of the contacts (5, 7) are also achieved by means of material reinforcements (11) provided in the region of the same. A multiple plug socket (2) is provided for passing through the housing wall (1) of the drive, which multiple plug socket (2) can be fitted in a pressure-tight manner, and has an internally located connecting plug board (3), which fit onto the connecting collars (5) of the input side end of the printed circuit board (6), so that it is now also possible to preclude damage from individual cables inserted together through housing openings, as always occured in the past. <IMAGE>

Title: Indicator light for motor vehicles in order to indicate to traffic behind that the driver wishes to park
Inventor: MAIER PETER
IPC: B60Q1/50
Filed: 1988-12-30
Abstract: Flashing with the direction indicator as is customary at present to indicate that the driver wishes to manoeuvre into a parking space is usually hardly noticed by traffic travelling behind. The result is that the car travelling behind approaches too closely so that it is no longer possible to manoeuvre backwards into the parking space. The new "parking indicator light" is intended to indicate unambiguously that the driver wishes to manoeuvre into the parking space. The new light is blue with a P in the centre and an arrow on the right and on the left. The new light is mounted at the rear of the vehicle. The "parking indicator light" is switched on by a switch on the dashboard when the driver intends to manoeuvre into a parking space. As a result, the traffic travelling behind maintains the necessary distance to permit backward manoeuvring into a parking space. After the parking manoeuvres are completed the light is switched off again.   <IMAGE>

Title: Method for braking a vehicle
Inventor: STRENZKE HILMAR DR ING
IPC: B60T1/08
Filed: 1989-02-24
Abstract: The invention proposes a method for braking a vehicle with a hydrostatic transmission, in which the driving engine accepts an overrun torque and, after the overrun torque that can be accepted by the driving engine has been exceeded, the kinetic energy of the vehicle is reduced at least partially hydraulically. According to the invention, it is envisaged that automatic brake application should then take place and the vehicle braked to a speed at which the overrun torque is lower than the overrun torque that can be accepted by the driving engine. This avoids the need for continuous hydraulic braking.
