Title: Hydrophobic filler prepd. from fused silica - treated with silane, partic. silazane, for use in moulded thermosetting electrical components
Inventor: SPORK CHRISTIAN R
IPC: C08G59/00
Filed: 1977-05-12
Abstract: Fused and finely-ground silica, having size 0.5-75 (0.5-20) mu, is used in prepn. of surface-treated, water-repellent silica fillers for crosslinkable polymers. Silica is free from heteroatoms, other than Si and O. Surface treatment is carried out so that silanol gps. Si-OH on silica surface are replaced by substd. silanol gps. Si-O-SiR1R2R3 (where R1,R2,R3 and hydrocarbyl, esp. lower alkyl, partic. Me). Filler is used in hardenable moulding compsns. for electrical components, partic. semi-conductor units having delicate, easily broken terminal- and connecting wires. Used of filler allows prodn. of hardened moulding compsns. having a heat expansion coefft. approaching that of metallic connecting wires in electrical components, e.g. 15-25 x 10-6/0X. High quantities of filler protect moulding against moisture penetration.

Title: Resistance welding wire grids - using ring electrodes which can be rotated when part of ring contact surface is worn
Inventor: PINGER EGON JAKOB
IPC: B23K11/30
Filed: 1977-06-15
Abstract: The electrode consists of a ring, which may have a polygonal periphery, and both ends of its bore are provided with a conical surface mating with corresp. surfaces on a carrier for the accurate alignment of the electrode; a coolant flows through the carrier. An annular cavity is pref. provided between the electrode bore and the carrier; the cavity is used for a coolant. The carrier is pref. designed to hold two electrodes. Used e.g. for resistance welding steel wire grids used for reinforcing concrete. The device uses an electrode ring which can be rotated by e.g. 10 degrees after part of its surface is worn or burned; when the entire periphery is finally damaged, the ring can be turned to a smaller dia. and re-used in the same way. The result is that the final "throw-away" wt. of the ring is very low; electrode costs are thus greatly reduced.

Title: Rotatable salt cake evaporator drum with internal fins - which dip into brine to form slurry for salt recovery
Inventor: PAPAFINGOS PANDELIS N
IPC: B01D9/00
Filed: 1977-12-22
Abstract: An evaporator system for recovering crystalline salt from heavy brine comprises an elongate drum which is inclined upwardly towards an output end and has fins mounted on the drum interior which make an angle of 5-85 degrees with the radius of the drum. The fins at the input end extend a smaller distance from the drum wall than those fins at the output end. The drum is rotated to cause the fins to dip into a body of brine in the drum. A stream of gas is simultaneously forced through the drum. An annular well is formed at the outlet end to provide a sump for the removal of brine from the drum. Used for treatment of salt cake resulting from the recovery of metal values in dross from Al refining. Evapn. occurs without the necessity of the liquid reaching b.pt. The rotation of the fins causes a disturbance of the liquid surface and increases the rate of evapn. The evaporator is self-cleaning with no build-up of salt on the evaporator surfaces. Al and aluminium oxide can be recovered with great efficiency.

Title: Conveyor for placing small articles in rows - uses sideways moving rack to remove articles from delivery channel
Inventor: MARB HANS
IPC: B23P19/04
Filed: 1978-02-22
Abstract: Small articles such as electrical contacts which are formed from short rods with enlarged heads are placed on a tray in order to be delivered to the next stage of manufacture. The tray has rows of small holes which receive the shanks of the contacts. The contacts are delivered from a vibrating conveyor into a slot with the head upper-most. As the contacts reach the end of the slot each contact slides into a space between the teeth of a long toothed rack which moves sideways. The tray is then moved upwards so that the shank drops into the holes and are retained after the rack moves away.

Title: Medicinal ampoule saw - with slotted spring protecting saw blade for nicking and breaking off ampoule pips
Inventor: FRANZES WERNER
IPC: C03B33/14
Filed: 1978-10-02
Abstract: A saw to cut off the pips of medicinal ampoules consists of an electric buzzer which reciprocates a saw blade in a handle. The saw blades are normally protected beneath a slotted spring steel strip; the teeth of the saw blade protrude when the steel strip is depressed by the ampoule. The pip is finally broken off by the pressure exerted by the spring steel strip and the pip drops into a box. The space below the box accommodates a transformer and a plug socket. This provides an easy way of breaking off the ampoule pips without any risk of injury. The saws, normally enclosed with each ampoule, can be saved.
