Title: Nonwoven fabric for plant protection in open land - has fibrous webs previous to air and water and interposed bonded network of equal or stronger texture
Inventor: NEUHAUS ERHARD
IPC: D06M17/00
Filed: 1991-09-12
Abstract: Fabric has an upper and lower fibrous web, which is pervious to air and water. In between the two layers of web is bonded a network of equal or stronger texture. The nonwoven fabric is pref. a web of staple fibre (12,14) from rolls (22,24), and it may contain thermosetting plastic, or have adhesive applied during construction, which fixes the web to the cross sections of the rectangular net (16) from the roll (26). This is made of material which is as strong, or stronger than the web. It may be polythene, polyester or polypropylene. These are then pressed between the rollers (30,32), which may have some form of heat treatment, and the fabric (10) is then rolled up. The size of the square of the net determines the size of cloche for each plant. USE/ADVANTAGE - The fabric provides plant protection in open land, for horticultural work. It is not necessary to remove and refix the protective cover, as the fabric allows water to percolate, and air to circulate.

Title: Shearing press for cutting up scrap metal - has hydraulic device to clamp upper blade which reduces time required to change blade
Inventor: LINNERZ WILHELM
IPC: B23D35/00
Filed: 1992-01-02
Abstract: The moving upper blade (3) is mounted on the press ram (2).

Title: Polymerised flexographic print plates - are moved slower through drying than washing with increasing support from below
Inventor: KONERMANN HERBERT
IPC: G03F7/30
Filed: 1992-09-17
Abstract: To produce polymerised flexographic printing plates, as they are dried with the image side upwards after washing out they are moved at a slower speed than during washing.

Title: Building material and machining device for coloured surface designs
Inventor: NEUMEIER TONI
IPC: B32B7/023
Filed: 1993-02-04
Abstract: Previous, essentially monotonous surfaces of objects are to be replaced, according to the at the same time also novel object of the invention, by the possibility of creating individual designs of the surfaces of these objects within their building material in a diversity of colours and structures. Provided for the surfaces of these objects are laminates, comprising colour substrates of various coloration and/or shading, for producing decorative and/or creative colour and geometrical structures by material removal. These laminates, suitable for machining for example with paring or milling tools, consist for example of wood, plastic or wax and are made in the form of sheets or as three-dimensional bodies. Serving to make, in particular, relatively small objects machineable are securing devices in the superficies, the moderate hardness of which protects the cutting edges from machining tools slipping off. The design example of an object, such as a mushroom (15, 16), machined from a laminate sheet (1) with various types of colour layers (2 to 14) using paring tools offers the viewer a colourful impression only in fact when the actual object is viewed. Possible applications exist, in particular, in the case of articles for everyday use and as art as well as jewellery, for encouraging creativity and for educational and therapeutic purposes. <IMAGE>

Title: Device for heating and/or cooling a driver's cab
Inventor: KHELIFA NOUREDDINE DIPL PHYS D
IPC: B60H3/02
Filed: 1993-02-06
Abstract: The invention relates to a device for heating and/or cooling a driver's cab, in particular a passenger compartment, a sleeper cab or the like in a motor vehicle. An air-inlet duct and an air-outlet duct are each connected to the driver's cab. The device has a sorption reactor which is filled with zeolite or the like and has an air flow passing through it via corresponding ducts, which air flow absorbs adsorption heat in the adsorption phase of the reactor while giving off moisture and, cooled by a humidifier, cools the inlet air flow to the driver's cab. A heating device is furthermore provided for heating the air flow for the desorption of the reactor, the heated air flow being conducted away with the moisture removed from the sorbent. In order to make sufficient heating capacity available even when the outside temperatures are low without loading the sorption reactor, it is provided to supply, via an air-flow control element, the air flow passing through the heating device either via a duct to the reactor or directly to the driver's cab as a hot air flow.

Title: Single page sheet feeder for copier, facsimile machine etc. - releases retaining projections on sheet cassette so that top sheet is in contact with feed roller when cassette is fully inserted into machine
Inventor: SHIRAI MASAMI
IPC: B41J13/00
Filed: 1993-02-26
Abstract: The sheet feeder takes sheets from a cassette (1) which is releasably connected to the image forming appts., e.g. copier or facsimile machine. The latter has a roller (71) for drawing the sheets from the cassette, which is fitted in a cassette guide (63a). The cassette has a sprung plate (20) which keeps the top sheet in contact with the feed roller when the cassette is inserted into the machine. Retaining projections (24, 42A) on the cassette prevent contact between the sheets and the feed roller during insertion into the machine. A release mechanism (91) frees the retaining projections when the cassette is fully in place, so that the feed roller is in contact with the top sheet. ADVANTAGE - Does not require space for upward shift of sheet cassette when inserted into machine.

IPC: B01J31/02
Filed: 1993-05-20
Abstract: A process for the preparation of aromatic amines by reducing the corresponding nitro compound with phosphorous acid in the presence of a heterogeneous palladium catalyst is characterised in that a phosphorous acid is employed which can be obtained as a by-product in the preparation of organic acid chlorides from organic acids and phosphorus trichloride. The process according to the invention allows aromatic amines to be prepared economically, in high yield, under mild conditions and in a chemoselective fashion. The process is also advantageous from the ecological point of view since it employs a waste material whose incineration or decontamination would involve high energy consumption.
