Title: Flame heating fabrics prior to steaming - as preheating during dye fixing
Inventor: FEESS ERICH DIPL CHEM DR
IPC: D06B21/00
Filed: 1977-09-12
Abstract: Flames are directed on wetted textile prior to its entry to a steaming chamber for dyestuff fixing. The water on the textile is raised to near its b.pt. Condensn. on the fabric during dyeing is avoided. Washing out of the fibre tips is thus reduced, dyed areas have a more distinct outline and residence times in the steamer are reduced. Pref. the flame is produced by gas jets arranged to spread the flame over the whole fabric width. The water in the fabric is raised to within 5 degrees C of b.pt. The water content in the fabric can be =50%. Steaming can be conducted at 102-140 degrees C. Dyeing can be conducted as a one or two phase fixing/dyeing process, e.g. with vat, sulphur or reactive dyes.

Title: Wireless closed loop alarm system - uses digital signals with ROM-controlled code and two transceivers with logic circuitry
Inventor: GRAUL JUERGEN DR ING
IPC: G08B13/18
Filed: 1977-10-21
Abstract: A wireless loop alarm system includes two transceivers with logic circuitry. The first transceiver includes a clock generator feeding a pulse counter and r.o.m.

Title: Dough dividing machine - includes rotating drum having dough portioning chamber from which dough is ejected onto conveyor
Inventor: MAIER ADALBERT
IPC: A21C5/04
Filed: 1977-11-02

Title: Bending tool for hollow metal sections - uses single external former to turn outer flange back against metal sheet
IPC: B21D5/16
Filed: 1978-04-18
Abstract: Hollow sections of trapezoidal cross-section can be formed on the ends of metal sheets (1) by first folding the sheet to form an open section with sides (2, 4, 5, 6, 7). The right angled edge of the section is then placed in a die (11) with mutually perpendicular surfaces (12, 13). A two part tool (14) then presses the sides (5, 6, 7) downwards until the outturned flange (7) lies on the lower side (2). The rounded edge (19) of the tool (14) forms a beaded edge on the finished section. This eliminates the need for an expensive mandrel to match the required internal shape.

Title: Mould for mfr. of screw-threaded castings or mouldings - has threaded core and guide nut, which is made in situ, for unscrewing the moulding
Inventor: ANDERSEN ANDERS ERIK
IPC: B29D1/00
Filed: 1978-05-29

Each guide nut is mfrd. in situ in the mould by casting in the same casting step as the moulding in the mould, and removed from it after each casting operation. Risk of damage to screw thread(s) of the moulding during removal from the mould is minimised. Mouldings with relatively log screw threads can be mfrd.
Patent DE-2827030-A1 (DE)
Inventor: CHRISTENSEN HANS DIPL ING
IPC: G21F9/30
Filed: 1978-06-20
Abstract: Before mixing the water-containing radioactive waste with cement, the waste is treated with a material which produces with the boric acid or the borate a compound which is difficult to dissolve in water or is a coordination compound. This method results in the solidification of the cement to form a solid product. The method is suitable for binding the water-containing, radioactive waste from pressurised-water reactors.

Title: Slab compacting appliance oscillation generator - has flyweight in each pair fixed on socket with externally variable phase setting
IPC: E02D3/074
Filed: 1978-06-21
Abstract: There are two parallel imbalance shafts, driven opposite ways, each bearing two flyweights, with selectively variable phase setting, on the oscillation generator serving for compacting work on slabs. The shafts (2, 3) are sited close together in a shared vibrator housing (1), force-or form-locked to each other.

Title: Lubrication of sliding electrical contact - depositing colloidal graphite on moving surface by potential-free graphite block
Inventor: KOHLHAAS PAUL DIPL ING
IPC: H01R39/22
Filed: 1978-10-18
Abstract: The proposed collector system reduces losses and wear associated with the conventional graphite brush and metal contact arrangement. The proposed assembly uses a metal to metal contact in which the moving contact is coated with a thin film of colloidal graphite. This coating is established by spring-loaded graphite blocks bearing on the sliding surface. These blocks are insulated from the electrical potential, and carry no current. The graphite assists in compensating for small surface irregularities on the sliding metal parts. It provides lubrication and also prevents the formation of single current carrying points. Experiments show that the contact drop at the sliding surface is about 22 millivolts compared with approx. 1 volt for a conventional carbon brush.

Title: LV high-power fuse with secondary solder fuse - shunts main fuse which is melted by heat in plastic casing of fuse
Inventor: HOLLMANN FRITZ
IPC: H01H85/46
Filed: 1978-11-11
Abstract: The LV HP fuse has a main fuse path and a secondary fuse path. The secondary fuse path opens when a given amount of heat is evolved by the fuse and thereby causes the main path to open. The secondary path (10) is located in the fuse casing separate from the space containing the main path (5). The fuse's casing is made of plastics. The secondary path consists of a solder bridge shunting the main path and located in a recess in the plastic casing such that the solder upon melting flows away into a reservoir (9, 9') irrespective of the position in which the fuse is fitted and thereby disconnects the two leads (11, 12) leading to the main path. The main path consists of a fusible conductor with a central constriction.

Patent DE-2852576-A1 (DE)
Inventor: GIRARD JEAN-BERNARD
IPC: A61C1/05
Filed: 1978-12-05
Abstract: In the dental handpiece, the tool is driven by an air turbine. This piece has two states of operation. In the first, the turbine rotates and a stream of water cools the field of work of the tool. In the second, these operations are interrupted; the air which actuated the turbine feeds a jet for purging the place being treated. The switching from the first state to the second is performed by pressing the button (32) placed in proximity to the end of the fingers during work. By this action, the flow of air in the turbine, which passed through the windows (33 and 36), is interrupted by the piston (30) which from then on closes the windows. In its new position, the piston (30) also closes the windows (34 and 35) through which the water passed. Conversely, it opens the window (37) and allows thereby the air which fed the turbine to form a purging jet. This handpiece may be used with a conventional installation with minimal changing of the existing parts. <IMAGE>
