Title: Cooled cord reel for electrical appliance - has apertures on retaining flanges to allow cooling air to flow inward
Inventor: MCALLISE GREGG A
IPC: A47L9/26
Filed: 1990-02-08
Abstract: The cord reel is cooled by allowing cooling air passing through. A hub is provided for the reception of a coiled cord. A terminal block provides connection of the coiled cord, attached to the hub. A bore in the hub allows at least a portion of cooling air to pass through. Slots in the terminal block communicate with the bore for allowing at least a fraction of the portion of cooling air to exhaust through. The cooled cord reel includes a relatively fixed housing. The fixed housing allows the passing of a total cooling air flow. Only a portion of the total cooling air flows passes through the bore of the hub. A hollow shaft can be disposed in the hub. A portion of the total flow of cooling air passes into the shaft and exhausts through a slot disposed in the shaft.
Patent DE-4013843-A1 (DE)
Inventor: LAING JOHANNES NIKOLAUS
IPC: F24S23/00
Filed: 1990-04-30
Abstract: The invention relates to a platform of the utilisation of solar power which makes use of linear concentrators to beam the solar radiation for use in thermal, chemical or photovoltaic solar power converters, in which the azimuthal movement of the sun is followed by rotation about the main axis. The aim of the invention is to ensure an approximately uniform conversion rate of the solar radiation largely independently of the height of the sun while avoiding the use of a twin-axis follower system. The area available for utilising the solar power is to be used as fully as possible as the aperture area to capture the radiation. According to the invention, a floating pipe (2, 2', 112) forming a torus is fitted as a frame for a horizontally extending planar bearer (3-4) held, by substantially evenly distributed buoyant bodies (13, 36, 46, 64a, 64b, 80b) borne by a liquid, at a vertical distance form solar power converting devices (33, 53, 73, 73', 93, 94b).

Title: Spinning frame - has top card can to feed sliver through vertical support arrangement into spinning unit below
Inventor: STAHLECKER FRITZ
IPC: D01H1/18
Filed: 1990-12-21
Abstract: A spinning frame utilises sliver from card cans which is carried down vertically to the drafting zone and is supported continuously by equipment installed for this purpose. Pref. the can is supported above a drafting zone, with the sliver turning around a larger grooved wheel at the top, and subsequently through the middle passage of a vertical series of grooved wheels with a half round groove. At least one of the wheels has a drive, and the whole series may be driven. The wheels in at least one section of the arrangement has the facility to deviate in direction to increase or decrease the friction surface. The sliver enters the drafting zone vertically, or alternatively this may be delivered into the rotor of an open-end spinning unit. As an alternative to grooved wheels, the sliver may be supported in the vertical section between the two surfaces of conveyor bands arranged to be adjacent, with both surfaces running in the same direction downwards. Some form of deflector band is required at the top in order to pick up the sliver as it leaves the can, and direct it to the downward moving bands. The conveyor band may have sprocket holes to regulate the drive. It may be a single continuous band furnished with pin projections to provide a grip on the siver. The band may take the form of a continuous steel band, running around rollers which include the top horizontal section to collect the sliver near the top of the can. USE - The sliver has to be fine count in order to be utilised at a spinning stage. This means handling becomes difficult, partic. when fed from above, out of a can. The continuous support arrangements overcome the difficulty.

Patent DE-4106034-A1 (DE)
Inventor: GORABLENKOW JOERG DIPL ING
IPC: H01F38/30
Filed: 1991-02-22
Abstract: A current transformer which can be installed in an earthed metal casing surrounding a high-votage conductor has an annular core surrounded by a toroidal secondary winding and is protected by structurally simple means from overvoltages at the secondary winding due to switching operations. As well as the secondary winding (5), the current transformer (2) has an additionnal winding (9) connected at one end to earth potential. The secondary winding (5) is shielded by the additionnal, earthed winding (9). The additional, earthed winding (9) also increases the total capacitance between the secondary winding (5) and the metal casing (1). The capacitance conditions of the capacitance voltage divider formed by the high-voltage conductor (3), the secondary winding (5) and the metal casing (1) are such that the secondary winding (5) is protected from overvoltages due to switching operations. The invention can be used in current transformers for encased switchboard plants.
Patent DE-4108203-A1 (DE)
Title: Prodn. of castings using two or more melts of different compsn. - has melt streams passing separately through prim. cooling chill moulds then into single chill mould
Inventor: YU GE
IPC: B22D27/20
Filed: 1991-03-14
Abstract: In the prodn. of a casting, in which the alloy compsn. or the microstructure varies across the cross section, the novelty is that the casting is made from several partly solidified melts or partly molten strips of different compsn.  which are brought together in a chill mould and then solidifed to form a complete casting. For further control of the process, an additional chill mould is positioned before the prim. chill mould in order to effect prim. cooling. USE/ADVANTAGE - Used for producing semi-finished prods. e.g.  rod, sheet, strip, piping etc. the method is a cheaper way to produce the desired properties without having to use a fully alloyed metal e.g. chrome- or nickel steel or  rely on surface hardening or enrichment.

Title: Spray unit for container cleaners - has bearing block in each nozzle area surrounding spray pipe and leaving spray window
Inventor: PURPER GUNTHER
IPC: B08B9/34
Filed: 1991-03-20
Abstract: The spray pipe (5) can turn about the longitudinal axis (L) relative to the shaft (16) whereby the nozzle (9) forming the spray jet (11) is only released in an angular range corresponding to the spray window (8). Outside of this angular range the nozzle is closed by the bearing block (7) or by a surface thereof enclosing the spray pipe (5). The shaft (16) which has brushes for cleaning inside the container does not turn about its axis and can be set coaxial or eccentric with the longitudinal axis (L) of the spray pipe. ADVANTAGE - It is now possible to separate the cleaning and spraying processes. The nozzles can be cleaned with the spray jet passing through the brushes to the container.

Patent DE-4132267-A1 (DE)
Inventor: PEUKER TINO
IPC: B60R13/10
Filed: 1991-09-27
Abstract: 2.1. The object of the invention is to permit the rapid and simple assembly of the numberplate despite the extremely small freedom of movement permitted by certain types of vehicle and in so doing to compensate for dimensional tolerances in such a way that numberplates with greatly varying heights can be fixed in a stable manner and the low-noise and reliable fastening of the numberplate is ensured. 2.2. This object is achieved in that the numberplate stiffening holder (1) has a covering strip (5) which is designed to be removable and which covers and simultaneously blocks a fixing device situated below it. The fixing device is designed as a closing device, which consists of closing holes (7) of a special shape with fixing keys (8) which are shaped so as to be insertable into said holes (7). 2.3. This solution is preferably applied when fastening numberplates in numberplate stiffening holders. This solution is especially suitable for vehicles in which there is an extremely small amount of space around the numberplate stiffening holder. <IMAGE>   <IMAGE> <IMAGE>

Inventor: REDMER BERND
IPC: G01R31/02
Filed: 1991-10-08
Abstract: According to the invention, in order to be able easily to check building wiring systems, especially those of control installations, use is made of a digital address allocated to the input or output concerned on all inputs or outputs of an electrical cubicle having wires to be checked. These addresses are allocated in a reference list of the field devices, e.g. sensors or servo-motors. In order to check the wiring, the addresses of the inputs and outputs of the cubicle on the field devices are read out via the cables connected thereto and allocated to the field device concerned in an actual list. A comparison between the reference and actual lists shows whether there are wiring defects and, if so, where.
