Title: Device for de-icing components consisting of any materials and being of any shape, particularly suitable for aerial-cladding structures
IPC: H01Q1/02
Filed: 1993-10-02
Abstract: The present invention relates to various devices for de-icing structures or components and is particularly conceived and suited for aerial-claddings. A de-icing device comprises, for example according to Figure 1, a close-fitting sheath (1) which is fitted on the outer surface of the structure/component, is prestressed, in particular, in a permanently elastic manner and/or is connected to the underlying surface by means of commercially available fastening means (3), for example, by way of sleeves (3), clamping strips (4) and, if appropriate, additional intermediate fixing means (7). The de-icing is based on the principle of the change in curvature of the contour of said sheaths (from rest state 1 to operating state 1') caused by static or pulsating internal pressure, with the result that attached ice is forced off and falls downwards. The devices are conceived in particular - but not only - for aerial-cladding structures, the walls of which have high-frequency electromagnetic waves radiated through them continuously or in sectors (cases I to IV according to Figure 1). For this purpose, the device can be adapted, from case to case, to the electromagnetic conditions of the cladding and thus of the aerial which is to be protected. In contrast to the prior art, which makes use either of mechanical or fluid de-icing processes, the advantage according to the invention lies in the fact that even locations which are inaccessible can be de-iced and mechanical damage is avoided and harmful fluids do not pass into the environment ...

Title: Baling press channel equipment
Inventor: HAWLAS MARTIN DIPL ING
IPC: A01F15/08
Filed: 1994-09-21
Abstract: Back-pressure is provided for the first bale to be compacted by an inflatable pusher which is made of flexible material so that it inflates to a section equal to that of the press channel (2) containing it. In a variant, the back-pressure is produced by a pair of swivel arms (8,9) rotating round an axis (10,11) clear of the channel so the free ends furthest from the swivel axes lie in the centre of the channel in relation to their active setting. Each arm moves towards the channel outlet against a piston and cylinder unit (13,14) and/or mechanical spring (15,16). To activate the arms, their guides alongside the channel swing the arms out at a set point from their (continuous line) initial setting so the arms swing into the channel just short of the infeed (12). In their rear setting (dotted lines) the arms swing right out as shown (8',9'). The axes adopt positions (10',11') in the rear setting.

IPC: F02B75/24
Filed: 1994-12-18
Abstract: In a two-stroke internal combustion engine with a crank slide mechanism and a plurality of working cylinders (11, 12), which have bases and are divided by a piston into a lower and an upper cylinder chamber, the lower cylinder chamber being used substantially for compression and the upper cylinder chamber (41, 42) being used substantially for combustion, storage cylinders are provided which can adjoin cavities (28) such as working cylinders of the engine and processing chambers, such that each adjoining cavity has at least one closeable inlet opening (33) through which an air-fuel mixture, for example, can flow from the storage cylinder into the cavity and at least one closeable outlet opening (31) through which the mixture can flow out of the cavity into the storage chamber (28). The storage chamber (28) is charged by the lower cylinder chambers (11, 12, 41, 42) with the air-fuel mixture and the mixture is fed as necessary to the upper cylinder chambers for combustion, or the mixture is conveyed out of the lower cylinder chambers into given compartments in the storage cylinder and from there is fed to the processing chambers for processing. After processing, the mixture is fed back to given compartments of the storage cylinder and then fed to the upper cylinder chambers for combustion. The storage cylinder enables losses by circulation to be avoided since the air-fuel mixture is not introduced at bottom dead centre of the pistons but during the compression stroke, i.e. when the outlet slot is closed.
