Patent DE-3842686-A1 (DE)
Title: Planting receptacle
IPC: A01G27/02
Filed: 1988-12-19
Abstract: The known planting receptacles provided with water-storage means usually comprise a plurality of individual parts plugged loosely one into the other and, due to the water absorbency of the plant, have a constantly sinking irrigation-water level. Changing irrigation-water levels have a disadvantageous effect on the plant growth. The novel planting receptacle is made in one part and has a vertically adjustable irrigation-water level which is always at the same level. In order to achieve this, the water-storage means (2) which belongs to the planting receptacle and, apart from the water-withdrawal opening (7) and water-introduction opening (14), is externally closed has a water-introduction shaft (12) opening at the bottom and is provided with a ventilation shaft (11) which, by means of a vertically adjustable regulating opening (10), opens at the bottom into the plant pot (1) of the planting receptacle. By virtue of this arrangement, the water-introduction shaft (12) of the planting receptacle and the plant pot (1) of the planting receptacle form a communicating receptacle. The planting receptacle is suitable both for cultivation with soil and for cultivation with a soil-free substrate. As a result of the irrigation-water level, in the plant pot, which is always at the same level, the planting receptacle does not require an irrigation-water-level indicator. <IMAGE>

Title: Light trunk piston for internal combustion engines
Inventor: RIPBERGER EMIL
IPC: F02B1/04
Filed: 1988-12-24
Abstract: A trunk piston for internal combustion engines is intended to run as quietly as possible with the lowest possible weight and small dimensions. For this purpose the piston skirt, in an area of a plane extending through the pin and piston longitudinal axis and situated on the counter-pressure side, presents a greater ovality than in that area of the said plane situated on the pressure side. In particular it is proposed that the skirt area situated on the counter-pressure side be less spherical in design in its upper area, that adjacent to the lowest ring groove, than on that skirt area situated on the pressure side. In addition it is proposed that the skirt on the counter-pressure side area at its upper end be separated from the piston head by a horizontal slot.

Title: Safety device for compressed air motor for tractor - shuts off air supply if excessive load is applied to air hose
IPC: B61B13/12
Filed: 1989-10-04
Abstract: The transport system in an underground mine has a tractor, for towing the trucks, powered by a compressed air motor. The compressed air is supplied through a flexible hose (2) which is supported on a plate (16) which is pivoted on a bolt fixed to a bracket (7) which is rigidly attached to the tractor (1). The plate (16) is normally prevented from pivoting by a shear pin (21). If an excessive load is applied to the hose (2) this pin (21) is sheared and the plate (16) swings about its pivot. This causes the flexible hose (2) to be compressed between a bolt (10) or (12) in the bracket and a bolt (18) or (19) in the plate (16), so that the air supply is shut off and the tractor is brought to rest. USE - Underground mining transport system.
