Patent WO-03085235-A1 (WO)
Inventor: TIEMANN PETER
IPC: B23P15/04
Filed: 2003-03-19
Abstract: Meandering cooling channels inside a turbine blade are difficult to produce in one piece by using casting techniques. The inventive turbine blade (1) comprises cooling channel walls (22), which are easy to produce by using manufacturing techniques and which later form the cooling channels (19), whereby the meandering shape is attained by an additional V-shaped insert after completion of the production process of the turbine blade.

Title: Shifting filter plates in a filter press
Inventor: HAECKER KARL
IPC: B01D25/172
Filed: 1968-12-05
Abstract: Shifting filter plates in a filter press Displacement is effected by carriers which can be swivelled on guide rails either side of the filter press.

Abstract: Perlite is treated pref. with a 40-140g NaOH/1. soln in a liq. solid ratio of 0.7-1.5:1 in an autoclave at e.g. 150 degrees C. The resulting aq. phase contg water glass (Na2O.3SiO2) is sepd. by filtration, and the solid residue is treated pref. with a 150-250 g NaOH/1. soln at or >=50 degrees C in a liq. solid ratio of 1.5:1 or 4-8:1, whereby sodium metasilicate (Na2O-SiO2) is formed in the first case, or sodium metasilicate monohydrate (NA2O.SiO2.9H2O) in the second case (the latter is crystallised when the filtrate is cooled to 15 degrees C). The undissolved Na-contg. aluminosilicate residue is dried to 5% moisture. One of the filtrates can opt. be treated with an alkaline earth metal hydroxide or Pb(No3)2 to produce the corresp. silicate. Due to the high purity of the starting material (perlite) the resulting alkali(ne earth) silicates are suitable for use in textile bleaching and washing compsns as fillers for paper, rubber, plastics, and other materials, as binders for cement, for the prodn of zeolites, etc. The process is technically simpler and less expensive than known processes, and high quality prods are obtd.

Title: Oil-cooled transformer reflex cooling system - has circulating pump in self-closing overload secondary cooling loop in parallel with main loop
Inventor: DOLAK GERHARD
IPC: H01F27/12
Filed: 1973-06-14
Abstract: The reflux cooling sytem has a secondary cooling loop containing a circulating pump in a parallel with the main cooling loop and brought into operation when the transformer is handling higher loads than usual. When the circulating pump is off, the secondary loop is closed by a freely hinge flap at the point where it joins the main loop at right angles. When the pump is operating the oil pressure in the secondary loop forces the flap open until it shuts off the main loop thus preventing oil the secondary loop flowing the wrong way round the main loop. The flap closes when the pump is switched off.

Title: Two-plug mains socket with spring contacts - uses double shank springs with U-shaped middle and partly bent edges
Inventor: FISCHER KARL-HEINZ
IPC: H01R25/00
Filed: 1973-09-03
Abstract: The insulating base body of the two-plug mains socket has two chambers of U-shaped cross-section and stretching longitudinally and symmetrical to both sides of the socket middle line.

Title: Safety device for an elevating platform - lifting nut runs with spaced capture nut on spindle and on change in nut spacing capture nut engages stop
Inventor: HOFFMEISTER CHRISTIAN W
IPC: F16H25/24

Abstract: Safety device for an elevating platform, especially a spindle operated platform where a lifting nut, which carries a lifting truck in a column, is guided on a spindle and runs with a spaced capture nut also on the spindle on normal raising and lowering. The capture nut under normal conditions when there is the constant, prescribed distance between lifting nut and capture nut lies against a stop and on reducing the distance, the capture nut comes out of engagement with the stop so that on relifting, because of the friction between spindle and capture nut, this nut turns so far with the spindle unit it comes into position below a fixed stop.

Title: Automatic safety release for seat belts - has cartridge release which explodes by heat of burning vehicle or after large inertial force
Inventor: BOCHMANN ERICH
IPC: B60R22/32
Filed: 1973-10-22
Abstract: The safety release device releases the belt when the vehicle catches fire and the occupants are able to free themselves. The anchor has a cartridge whose explosive charge is ignited due to heat. The anchor is disconnected when propellent gases eject a pin which holds the belt anchorage in the bracket so that rings are pushed outwards and separated. The charge is initiated by a mechanism which has a low melting point plug made for example from wax, paraffin wax or a material which is readily ignited. The plug releases the firing pin, and is used in conjunction with a post-impact inertial release.

Title: Fastening profile for acoustic wall and ceiling cladding - is held on a levelling wedge and has hooking ribs
Inventor: WILDEROTTER GERHARD
IPC: B44C7/02
Filed: 1973-10-30
Abstract: The fastener is used on fitting effective wall and ceiling claddings in which the panels are fitted a certain distance away from the walls by means of self-locking profiles. The material used for cladding is a textile fabric which is stretched to form highly decorative and noise insulating cladding. The clamping profile is held by its underside on a wedge by a screw. The wedge ensures that the level of the clamping profile can be adjusted to required value on constructing the wall cladding. The continuous long profile is U-shaped and the upper open end edges are turned inwards to form the re-entrant sharp locking edges. The fabric can be readily pushed through the slots between the hooking edges and positive locking is achieved by the sharp edges of the locking profile. Good tight joints are formed between fabric panels which meet at the locking profile and whose edges are pushed together through the slots. A clearance is formed between the fabric and the solid wall and this contributes to noise absorption. The fabric is stretched by simple tools and good uniform appearance obtained readily.
Patent DE-2358867-A1 (DE)
Title: Multiple section partition wall - has each pivoting section attached by carriage to rail fixed on ceiling
IPC: E05D15/06
Filed: 1973-11-26
Abstract: The partition wall sections are positioned side by side, and each one is attached to a roller-carriage, placed in the section's centre. The support or carriage enables the section to be moved along a rail fixed to the ceiling, and to be pivoted across the rail when it reaches its positioning point. A guide-piece inserted in the rail a little way from the support is detached when the partition pivots. One of the sides of the rail has an aperture, in the pivot area, and one of the cheeks of the rail has a gap enabling the guide-piece to go through. A stop-piece on or in the rail prevents the partition wall from moving out of position.
