Title: Resistance compensation by variable negative resistance - uses circuit which compensates for losses in electronic switches whose ohmic resistance and impedance differ
Inventor: GASSER LORENZ
IPC: H03K17/06
Filed: 1974-04-22
Abstract: An electronic switch, a variable resistance and a source of alternating measuring current are connected in series to form a circuit. As signal to be transmitted is introduced into the circuit by convenient coupling elements, for example by transformers, a constant gain amplifier is provided at the exterior of the circuit to amplify the signals. The transformers are shunted by first isolating networks which give an open circuit to the frequency range of the signal and a short circuit to the frequency of the alternating measuring current. The alternating current source is shunted by a second isolating network which gives a short circuit for the frequency range of the signals and an open circuit for the measuring current frequency. The circuit has a control and comparison circuit which adjusts the variable resistance so that the total resistance of the circuit takes a constant predetermined value.

Title: Hexagonal torque transmission element - has load applied to convex sides to protect hexagon corners from overstressing
Inventor: YAMAMOTO TOSHIJI
IPC: B25B15/00
Filed: 1974-09-12
Abstract: A hexagonal screw head has radial convex curvatures (26) on its spanner flats (20). When a standard hexagon or fork spanner is used to apply a torque to this screw head, the forces are transmitted to the hexagon at two opposite points along the curved flats, away from the corners. This protects the hexagon corners (22) from damage due to excessive compressive loading. The same principle applies to internal hexagons, in which case the convex curvature of the hexagon faces is radially inwards.

Title: Light hand pistol for driving in thermoplastic-coated dowels - uses hot air to melt the plastic before the dowel is driven
Inventor: NICKLAS WALTER
IPC: B23Q11/14
Filed: 1974-07-19
Abstract: When the trigger is pressed, compressed air (from 3) passes to an electric heater (15) temperature control (49) and on to an annular chamber (30) surrounding the barrel of the pistol (8). Small openings (33) allow the hot air to pass on into the barrel itself, where it heats the thermoplastic coating of the cowel (12) heading the file in the magazine (9). When the air in the annular chamber is hot enough to have melted the plastic, a temperature sensor (45) causes a magnetic valve (43) to open, admitting the compressed air to the operating cylinder (1), whose piston drives the dowel into its hole. When the trigger is released, the air flow through the electric heater ceases, and the temperature in the annular chamber falls. The temperature sensor (45) then releases the magnetic valve (43), cutting off the air supply to the piston, and allowing all parts to return to their starting positions.

Title: Synthetic rutile titania mfr. - simultaneously producing chlorine and ferric oxide from gaseous iron chlorides
Inventor: DUNN JUN WENDELL EARL
IPC: C01B7/03
Filed: 1975-06-28
Abstract: A fluidised bed of titaniferous ore mixed with 10-30% by wt. of coke is contacted with Cl2 at elevated temps. to produce a partially chlorinated product. The iron oxide contained in the titaniferous ore is selectively converted to iron chlorides and the process is carried out in a reactor having a chamber above the fluidised bed. The improvement comprises producing chlorine and ferric oxide from the gaseous iron chlorides by contacting the chlorides heated to 1250 degrees to 1380 degrees K, with oxygen in the chamber above the fluidised bed of titaniferous ore to form a gaseous cloud comprised of a partially oxidised mixture of iron chlorides, iron oxide, iron oxide nuclei, oxygen and chlorine. The partially oxidised mixture is passed through a cooled flue, at a superficial velocity of >=50 ft/sec. The remaining iron chloride is further oxidised to chlorine and an equilibrium layer of ferric oxide formed on the inside wall of the flue is continuously abraded by iron oxide solid product passing through the flue. The chlorine is separated from unreacted ferric chloride and ferric oxide. Simple process for the production of chlorine and iron oxides adapted to use ferric chloride and ferrous chloride also providing economies by utilisation of some of the heat produced by oxidation of the iron chlorides and which eliminates plugging problems prevalents in prior art processes.
