Filed: 1947-11-05
Abstract: 647,401. Heating buildings. DALIN, D. Nov. 5, 1947, No. 29543. Convention date, May 7, 1946. [Class 64(ii)] A steam-boiler 1 connected to a steamcollector 2 supplies a steam-water mixture through a conduit 3 to heat-consumption apparatus 5 where the heat given up is the latent heat of condensation, the mixture having substantially the same temperature on leaving the apparatus as on entering and from the apparatus the mixture passes through conduit 4 to the collector. The flow-and-return conduits 3, 4 are connected by two byepass conduits 6 in which the flow is controlled by a regulator 7 and reduction valve 8 respectively. Two circulation pumps 10, 11 connected in parallel are interposed between the collector and the boiler, valves 12 controlling the flow through these pumps. One pump 10 is driven by a turbine and the other pump 11 is driven electrically. Each heat-consumption apparatus has shut-off valves 14. A steam take-off 15 leads steam from the collector to other steam consumption apparatus.

Title: Arrangements for biasing the substrates of integrated circuits
IPC: H01L21/339
Filed: 1973-06-25
Abstract: 1372679 Field effect transistor circuits BATTELLE MEMORIAL INSTITUTE 25 June 1973 [27 June 1972] 30167/73 Heading H3T [Also in Divisions H1 and H2] An arrangement for biasing the substrate of an integrated circuit comprises a series of n IGFETs each having a source and a drain region and a gate connected to the drain region, the source regions being formed by n zones, designated M and Z 1  to Z n-1  in Fig. 1, of opposite conductivity type to the substrate, which is P type in the example, the drain regions of the first to (n-1)th IGFETs being formed by the second to nth zones respectively, designated Z 1  to Z n-1  in Fig. 1, and that of the nth IGFET by a further zone Z n . A signal generator C1 provides at each of its outputs (two in the arrangement shown) a periodic signal time displaced with respect to corresponding signals at the other outputs, the outputs being connected in alternating sequence to electrodes C 1 -C n  capacitively coupled to the second and (n+1)th zones designated Z 1  to Z n . Cl may be a multivibrator or symmetrical oscillator integrated in the substrate. If capacitances C 1  to C n  are large relative to the capacitances between zones Z 1  to Z n  and the substrate it can be shown that electrons are transferred through the transistors from zone M to zone Z n  where they are injected into the substrate until it reaches a stable negative voltage high compared with that of D.C. supply S and of the pulses delivered by generator C1. This enables the substrate to be more lightly doped while ensuring that IGFETs of other circuits formed in it have positive threshold voltages. This enables the drain capacitance to be kept low thus ensuring the high transconductance/input capacitance ratio required of IGFETs in low consumption HF circuits. The minority carrier injection giving rise to detrimental bipolar effects in integrated MOS capacitor pull up circuits for instance is also avoided by biasing the substrate as described above. In a modified circuit, to eliminate minority carrier injection from zone Z n  resulting from hole-electron pair generation under equilibrium conditions, this zone forms the source of a further IGFET the gate of which is connected to its drain and to a P + inclusion in the substrate.

Abstract: 918,831. Eddy-current couplings. BOSCH G.m.b.H., ROBERT. Aug. 24, 1961 [Sept. 10, 1960], No. 30489/61. Class 35. [Also in Group XXVII] In an I.C. engine having fuel injection and separate ignition, a fuel delivery adjusting member 29, Fig. 1, is moved according to engine speed through a rotary magnetic clutch comprising a rotatable short-circuited armature 6 arranged in the field of a rotatable permanent magnet 4, one clutch part being engine-driven and the other clutch part being mechanically coupled to adjust the fuel delivery adjusting member according to the clutch-transmitted torque, the influence of the magnetic field of the permanent magnet upon the short-circuited armature being variable as a function of the position of the throttle 21. The permanent magnet 4 is driven from the fuel pump driving-shaft 2 in accordance with engine speed and tends to rotate the shortcircuited armature 6 until equilibrium is established between the torque produced by the magnet, the induced currents in the armature and the counteracting twist in torsion bar 14. Rota. tion of the armature sets the fuel delivery adjusting member 29 through pin 24, rod 25 and crank 26. When the intake pipe throttle 21 is opened, a directly connected cam-plate 19 displaces bush 9 and the assembly of the adjusting screw 15, torsion bar 14 and shaft 7 to create a bigger gap between the magnet and the armature, thus reducing the transmitted torque. The torsion bar can then rotate the armature to cause injection of a greater fuel quantity. An auxiliary cam-plate 20, acting through lever 36 and shaft 32 to displace the pivot 27 of crank 26, provides additional adjustment of the injected amount. An engine thermostat 40 acting through lever 38 on the pivot 37 of lever 36, provides a richer fuel/air mixture with a cold engine. Reduction of the transmitted torque caused by heating of the armature is compensated by bi-metal strips 46, Fig. 3, which when heated, displace the armature to reduce the gap. In another embodiment the armature is driven by the injection pump and revolves between two pairs of magnets which are mutually displaceable through 180 degrees, by a pin and oblique slot arrangement, to reduce transmitted torque. In a further embodiment torque is transmitted between a pump-driven armature and two horse-shoe magnets arranged on an axially displaceable carrier.

The member 6 has a flange 5 against which the piston impinges in the maximum mould opening position, the piston has an axial blind bore 9 to receive one end of the tube 7 and part of the member 6. The latter is adjusted on the tube 7 by a dog 12 secured to a spindle 8 rotated by a hand wheel, the dog engaging within axially extending slots in an extension 11 extending axially of the member 6. Pressure fluid is supplied to the motor at 16 and 21 for effecting mould closure and opening respectively. When closing the mould from a fully open position, as shown in the top half of Fig. 2, the pressure fluid opens a one-way valve 19 and connects with the blind bore of the piston; on mould opening the fluid in the bore cushions movement of the piston against the stop flange 5.
