Title: Apparatus and Method for "Foamed-in-Place" Insulation of Vertical Surfaces.
IPC: B29C63/02
Filed: 1966-10-03
Abstract: 1,154,147. Applying thermal insulation to surfaces. CHICAGO BRIDGE & IRON CO. 3 Oct., 1966 [8 March, 1966], No. 44064/66. Heading F2X. [Also in Division F4] Vertical surfaces particularly of gas and liquid storage tanks are insulated by positioning a roll 50 of sheet material housed within an apparatus 18 adjacent the vertical surface 12, securing the end of the roll away from and in a fixed position relative to the surface, displacing the roll and unwinding the sheet material whilst maintaining it spaced from the surface, and depositing partially foamed insulation 124 between and in contact with the vertical surface and the unrolled sheet material at a rate commensurate with the unrolling of the sheet material. Final expansion of the foam occurs within the space between the vertical wall and the unrolled sheet material and is facilitated by previously warming the vertical surface with a heater 128. The foam composition can result in either flexible or rigid foam insulation and may be a resin foam, a flame retardant foam or a self-extinguishing foam of the polyurethane type. It is supplied from a reciprocating gun 126. The sheet material can be formed from aluminium foil or sheet steel and can be glued to spacers 62 e.g. of rigid polyurethane formed on the vertical wall. The spacers restrain the foam from lateral displacement but slidably mounted shoes or a wide endless belt positioned laterally to the vertical surface can be used. The roll 50 can be positioned with its axis horizontal and displaced upwardly on rotation of winches 78, or with its axis substantially vertical and displaced horizontally during unwinding of the roll. The sheet material may be riveted to the bottom of the tank structure and at the top to a flashing, sealing being provided by mastic.

Title: Driver circuit for inductive loads
IPC: H03K17/64
Filed: 1975-10-31
Abstract: 1504190 Transistor switching circuit INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [31 Dec 1974] 45271/75 Heading H3T To drive cyclically, e.g. at 200 Hz, an inductive device 7, e.g. a solenoid, from power supply 18, a preset ON voltage is applied for part of the cycle (Fig. 1, not shown) causing the current to grow, followed by a period during which no voltage is applied, the rapid current decay in the inductance being allowed to generate a higher back e.m.f. driving the stored energy back into the supply. Under the control of a rectangular voltage waveform at terminal 1, negative-going during ON periods, transistor 33 causes node 24 to follow an inverted wave; during ON periods diode 29 blocks, leaving non-inverting input 28 of the amplifier in integrated-circuit voltage regulator 27 to take up the reference potential of terminal 35: the regulator output 43, dropped in potential by the voltage of Zener 42, switches ON transistor 49 and thence transistor 50, allowing current to flow through the split primary windings 47, 53 of the pulse transformer. The secondary winding 59 supplies a corresponding pulse, of height set by the turns ratio and the supply voltage less the drop across transistor 50, to the devices 7 which may be a plurality of solenoids selectively grounded via individual switching circuits 9. The voltage across the selected devices is maintained constant independent of the number connected by line 60 feeding back a fraction set by potentiometer 62 to the inverting input 36 of the regulator 27. At the end of the ON period the control votage at terminal 1 rises, causing that at 24 to fall and allowing that at 28 also to fall via diode 29, so switching OFF transistors 49 and 50. The inductive reverse e.m.f. in the load, which comprises the selected solenoids and winding 59, induces an e.m.f. in winding 55 sufficient to overcome the supply voltage, thus limiting the voltage across the devices to a value set by the turns ratio of windings 55 and 59 to be higher than the drive voltage, and allowing energy to be fed to the supply via diode 58. Resistor 57 ensures near-zero residual magnetism in the core at the beginning of each ON period of the cycle. The invention may be applied to an intermittent document transport device.

Title: Electrical to fluid signal transducer
IPC: F15C1/04
Filed: 1969-09-15
Abstract: 1,235,980. Electrical to fluid signal transducer. MESSERSCHMITT-BOLKOWBLOHM G.m.b.H. 15 Sept., 1969 [21 Sept., 1968], No. 45427/69. Heading G4P. [Also in Division G3] An electrical to fluid signal transducer has a fluid inlet 2, two fluid outlets 3, 4, two electromagnetic devices 9, 10, and a ferromagnetic signal element 5 which can be moved into one or other of the outlets by the fluid and held there by the electromagnets. If there is no electric signal to either electromagnet, fluid (liquid or gas) accumulates above arm 6, which blocks passage 3, until it overflows into passage 4 when the inlet flow is held in passage 4 by the Coanda effect. Eddies under abutment 20 draw the other arm 7 about pin 8 into the stream where it is pressed to the left hand wall by fluid pressure. Fluid then accumulates above arm 7 and the cycle is repeated in oscillations of the outlet flow down passages 3, 4. A gap or holes between the two sides of the member 27, 28 presents damping of oscillation. If an electric signal activates an electromagnet (only one at a time) the appropriate arm is held to that electromagnet until the signal is released. The housing 1 is non-metallic. The element 5 can be shaped and positioned differently (Figs. 2, 3, 4, not shown) and adjustment channels (23, 24, Fig. 4, not shown) can be used to counteract lack of symmetry in the fork 5 and can also vary the switching time of the oscillations.
