Title: Fertiliser prepd. by composting conifer bark - by mixing ground bark with ammonium bi:carbonate and water
Inventor: REBHOLZ ALBERT
IPC: C05F11/00
Filed: 1980-10-23
Abstract: The prepn. of a soil improving agent by composting conifer bark, comprises grinding fresh conifer bark to particle size 0-18 mm and then mixing with 1-2 kg (per 1000 l fresh bark) of pure nitrogen in the form of ammonium bicarbonate, and with 70-80 wt.% water to give a homogeneous mixt. which is then composted. The conifer bark is pref. from a spruce tree, a fir tree or a pine tree. Pref. the composted bark is enriched with ca 25-50 vol.% peat with degree of decomposition H6 to H10, opt. with the addn. of plant nutrients, to promote plant growth. Pref. the end prod. has total N; P2O5; K2O (insol) of 1:1:1.5 or 2:1:1.5 or 4:1:1.5. The novel fertiliser smells like fresh forest soil, is dark in colour and is a good absorber of water (62% at pH 0.6). None of these properties are possessed by calcium nitrate as nitrogen carrier. The bacteria present in the bark need nitrogen to synthesise their protein; ammonia is a considerably better source of this than nitrate.

Title: Lightweight-construction wind-screening jacket
Inventor: KLEINWAECHTER JUERGEN
IPC: E04H1/12
Filed: 1981-09-17
Abstract: Lightweight-construction wind-screening jacket for screening equipment, in particular large solar reflectors, from wind forces and for avoiding dust contamination and other negative environmental influences. For the purpose of installation using only manual means, the screening jacket is, according to the invention, separated into a multiplicity of movable, interconnected sheet-like parts which, in turn, can be folded in a planar manner outwards onto the ground in sector form. The individual sheet-like parts comprise stable frames which are reinforced via diagonal cables and are provided with means in order to brace corresponding screening jackets in a flutter-free manner. According to the invention, after installation of the screening jacket on the ground, said individual sectors are moved into their end position by means of traction cables, via an auxiliary tower. The same traction cables serve to stabilise the lightweight-construction wind-screening jacket mechanically after the frame has been erected. In the event where no foundations are present, the wind-screening jacket may, according to the invention, be provided along its periphery, on the ground, with a channel which is filled with heavy material (sand, stones, etc.).

Patent DE-3209627-A1 (DE)
Title: Propellant body for high-powered barrel weapons
Inventor: WEISE CHRISTIAN
IPC: F42B5/38
Filed: 1982-03-17
Abstract: The use of conventional propellant-body ammunition with fin-stabilised or spin-stabilised projectiles entails disadvantages, particularly     a) a high total ammunition weight, b) gas losses as a result of the rigid design of conventional propellant bodies, c) propellent-charged case production, case splitters and the like.   The invention reduces these disadvantages in that the propellant body is designed at the same time as a propellant-charge carrier. This propellant body/propellant-charge carrier is subdivided into a thick-walled head piece, a propellant-body envelope thin-walled in relation to this and enveloping the propellant charge, and a bottom piece which combusts during the firing operation. The advantages are   a) a reduced total ammunition weight, since there is no propellant-charge case, b) less gas slip as a result of a pressure-related sealing effect of the thin propellant-body envelope, c) absence of propellant-charge case production, omission of case clamps and the like, d) when a combusting bottom piece is used, equivalence to caseless ammunition is provided. Furthermore, there is the possibility of using a bottom piece of conventional design which separates from the propellant body/propellant-charge carrier (predetermined braking point) during the firing operation and which is thereafter conventionally removed from the weapon by extraction and ejection. o

Inventor: KOLLMANNSBERGER OTTO
IPC: G01R31/34
Filed: 1982-03-26
Abstract: In a circuit for supervising the wear of carbon brushes making normally contact with a commutator of a direct-current electric motor of an electrically operated vehicle powered by an accumulator, and which includes main on-off switch for starting and stopping the vehicle, electrically insulated control brushes carried by the carbon brushes, and movable therewith, and a warning signal indicator normally connected to the control brushes, which provides a selectable optical and acoustic warning signal when the control brushes establish contact with the commutator upon a predetermined degree of wear of the carbon brushes, the improvement includes an electrical memory which has set and reset inputs, is connected to the control brushes, and controls the warning signal indicator. The control brushes set the memory upon establishing contact with the commutator. A switching device switches the warning signal indicator into, and out of the circuit, and the memory, upon being set, automatically actuates the switching device for switching the warning signal indicator into the circuit, independently of the establishment of the contact of the control brushes with the commutator; the memory is reset upon actuation of the main on-off switch.

Title: Method and device for removing surplus developer in recording apparatuses using liquid developer
Inventor: HINZ HANS-DIETER
IPC: G03G15/11
Filed: 1982-08-19
Abstract: In order to develop a charge image (7) which is deposited on a dielectrically coated image carrier (1), the image carrier (1) is wetted with a liquid developer (8) consisting of a dispersant and toner particles. By means of the charge image (7), a portion of the toner is bonded, in terms of the image, on the surface of the image carrier (1). The remaining toner must be removed to avoid producing any background toning. In addition, the amount of dispersant which remains on the image carrier (1) is intended to be only as much as is required for the further treatment of the developed charge image (7) to be carried out correctly and quickly. For this purpose, a deposition (precipitation, separation) device (3) is provided which is moved relative to the image carrier (1) and whose surface just still dips into the liquid developer (8) which is deposited on the image carrier, so that a portion of the dispersant contained in the liquid developer is removed, for example by adhesion. In addition, an electrical field (14) is applied between the deposition device (3) and the image carrier (1). The direction of this electrical field (14) depends on the charge of the toner which is used in the liquid developer (8). The toner (10) which is not bonded in terms of the image is drawn off the deposition device (3) by this electrical field (14). <IMAGE>
