Title: Revolving hollow clamping cylinder
Inventor: BRANGS ECKHARD DR ING
IPC: B23B31/30
Filed: 1986-09-26
Abstract: In this hollow clamping cylinder for actuating the clamping tools on work spindles of machine tools, gap seals are formed in the transition area between a fixed housing (6) and the hollow-shaft-like section (4) of the cylinder (1) rotatably mounted therein owing to the fact that sealing rings (12) run between face plates (9) which are restrained axially on the housing (6) via distance rings (10). The sealing rings (12) lie at an axial distance from the distance rings (10) and form sealing gaps (11) running radially with the facing surfaces with the face plates (9). The pressure medium is passed through via radial passages (13, 14) in the distance rings and sealing rings (10, 12). The radial sealing gaps can be kept very small without interference-factor influence, which can also be achieved cost-effectively in production by simple grinding and lapping. Gaseous pressure media with very low leakage loss and very low frictional heat in view of their low viscosity can therefore be used. <IMAGE>

Patent DE-3713949-A1 (DE)
Inventor: MUELLER KARLHEINZ DR ING
IPC: B65D81/26
Filed: 1987-04-25
Abstract: Long-term desiccation apparatus in wrappings, packages and transport containers for moisture-sensitive goods and articles is based upon a combination of barrier layer envelope, desiccant container 1 and desiccant, in which the desiccant does not come into action until the packaged goods are at risk. The automatic and intermittent air exchange is achieved by direct and/or lever-assisted action of materials of the desiccant container that are sensitive to air humidity, in that flap-shaped incisions 9 are formed in the composite material of the desiccant container; due to the "rolling effect" intrinsic in the material, open or close access to the desiccant is obtained as required. In an example the desiccant container consists of vulcanised fibres on the inside of which aluminium foil is glued. If the relative air humidity rises the moisture absorption of the layer of vulcanised fibres increases, which leads to expansion of the fibres, the hydrophobic aluminium layer remaining unchanged. <IMAGE>

Patent DE-3722220-A1 (DE)
Title: Labelling apparatus for upright containers
Inventor: WINTER HORST
IPC: B65C9/18
Filed: 1987-07-04
Abstract: There is known an apparatus, in which individual labels are cut off from a continuously moved label tape by means of rotating knives. A disadvantage of this, however, is that, in the event of a gap in the container stream, labels not required continue to be applied to the pallet rotor and coated with glue, and this can lead to a soiling of the machine and to operating faults. In contrast to this, in the event of a fault in the container feed, the labelling apparatus makes it possible to increase the distance between the vacuum cylinder (3) and the pallet rotor (6), with the result that a controlled interruption in the label transfer is possible. The labelling apparatus can be used for the labelling of bottles and other containers. <IMAGE>

IPC: C22B7/00
Filed: 1987-09-07
Abstract: Batches of hydroxide sludges are successively converted with various reagents in a reaction container, thus transforming by oxidation the chrome hydroxide into chromate. The zinc hydroxide is extracted by alkalis. The chrome hydroxide in the residue of the alkali processing is oxidized into chromate. Copper and nickel are extracted with acids from the oxidation residues. The remaining residual sludge contains essentially iron hydroxide. Copper oxide is precipitated from the solution, separated from the nickel solution and finally dissolved in acid. The separation can be carried out in a single container and supplies the separated components of the hydroxide sludge in a form that allows these components to be recuperated as useful materials.

Patent DE-3740384-A1 (DE)
Title: Locking unit for hydraulic clamping elements
Inventor: RICHTER KLAUS DIPL ING
IPC: B25B5/08
Filed: 1987-11-28
Abstract: The invention relates to a locking unit for hydraulic clamping units. Such clamping elements serve for clamping moulds and tools or workpieces on machine tables in a straight clamping surface. A hydraulically moved wedge bolt exerts in this case a force on the clamping piece and secures it, the wedge bolt usually being guided in a self-locking manner. In order to prevent the piston rod sliding into the relaxed position during the clamping process as a result of an incorrect engagement in the hydraulics, a locking system is provided, which secures the piston rod until its unlocking is carried out. This locking system can be positive and non-positive so that the pressure exerted on the fastening part via the piston rod is also maintained with the aid of the locking unit.

Title: Exhaustive discharge protection for the starting batteries of motor vehicles, in particular in passenger cars
Inventor: WEMHOENER JUERGEN
IPC: B60R16/02
Filed: 1987-12-14
Abstract: Discharging of the starting battery by the vehicle's electrical system after the vehicle has been switched off by loads which have been left switched on inadvertently is unavoidable according to the prior art. Despite various warning devices which can be installed as part of series equipment or retrofitted total failure of starting batteries or premature ageing thereof occurs repeatedly. The problem cannot be overcome with warning devices alone. Therefore, the objective must be to provide a protection device for starting batteries which reliably prevents exhaustive discharges by the vehicle's electrical system. The technical object is achieved in that, after the ignition key is withdrawn, the battery voltage is continuously monitored by a new circuit (Fig. 2). If the battery voltage drops below an adjustable limit value, the entire electrical system of the vehicle is disconnected by a bistable relay. The area of application comprises all passenger cars and delivery vans or such motor vehicles which are equipped with a combined starter/electrical system battery. <IMAGE>
