Title: Process for the preparation of a polyurethane foam
Inventor: ROVEA ZAVERIO
IPC: C08G18/65
Filed: 1967-01-09
Abstract: Polyurethane foams are prepared by reacting an organic polyiso(thio)cyanate with a wood resin having a softening point of at least 70 DEG  C. and a low M.W. polyol having a hydroxyl number of at least 1000, in the presence of a catalyst which is an amine or a bi or a quadrivalent tin compound, a foaming agent and, if desired, a surface active agent.  Conventional aromatic polyisocyanates, polysiloxanes as surface active agents, and water and volatile organic compounds as blowing agents are preferred. The preferred wood resin is a commercial pine wood resin with a softening point of about 112 DEG  C.  The low M.W. polyol is suitably trimethylolpropane, hexane - 1,2,6 - triol, pentaerythritol, sorbitol, mannitol, glucose, sucrose, glycerol and triethanolamine.  Flame retardants such as trichloroethylphosphate, tri-(2,3 - dibromopropyl) phosphate, diammonium phosphate, red phosphorus and antimony oxide may be added to the reaction mixture.

Title: Improvements in or relating to methods of modulating carrier waves
IPC: B01F7/16
Filed: 1936-01-15
Abstract: 468,959. Modulating systems. FERNSEH AKT.-GES. Jan. 15, 1936, No. 1315. Convention date, Jan. 15, 1935. [Class 40 (v)] Modulating frequencies are balanced out in the outgoing circuit of a modulator valve, by applying both modulating signal and carrier wave to the modulating valve, and applying the modulating signal alone to a balancing valve. As shown in the Figure, the carrier is applied to the coil 2 in the grid circuit of the modulating-valve 1, in series with a signal voltage derived from the impedance 5, and a modulated carrier wave is taken off across the plate circuit impedance 7. A signal voltage in phase opposition to that applied to the grid of valve 1 is applied to the grid of an amplifier 8, the plate of which is directly connected to the plate of the valve 1, so as to balance out the signal voltage in the common plate circuit. The impedance 7 may be centre-tapped and connected through capacities to the grids of valves 1, 8 so as to neutralize their inter-electrode capacities, Fig. 2 (not shown) ; or screen-grid valves may be used. Instead of dividing the signal-input impedance 5, the necessary phase relation in the common plate circuit may be produced by using a pair of resistance-coupled valves instead of the single valve 8, Fig. 3 (not shown. The carrier input and the signal input may be applied to separate grids when multi-grid valves are used, Fig. 4 (not shown).

Filed: 1936-01-16
Abstract: 468,075. Delivering articles from containers. CUNNINGHAM, W. Jan. 16, 1936, No. 1396. [Class 78 (i)] [Also in Group XVII] Apparatus for decorating cakes, in which cachous and the like are delivered singly in succession from a container, comprises in combination a container, a conical portion connecting the container to a delivery tube, and a looped resilient wire secured to the tube, which, in addition to carrying a bent member near its lower end entering a slot in the tube, has its lower end bent round the tube so as to project into an opposed slot in the opposite side at a lower level than the bent member, the arrangement being such that the application of pressure to, and subsequent release of, the looped resilient wire causes the projections to protrude alternately into and be withdrawn from the tube so that the articles are released one at a time to fall by gravity down the tube. As shown, a lidded container 1, into which the cachous are tipped is connected by a conical portion to a tube 4 in which the cachous arrange themselves in a pile. A finger-pressed looped resilient wire 6 is bent at 6a and carries a bent arm 8, the members 8, 6a entering slots on opposite sides of the tube. Normally, the member 6a supports the pile, but by pressing the spring inwards, the lowest cachou is separated and the pile supported on the bent arm 8. At the same time the member 6a is withdrawn to deliver the separated cachou by gravity. On releasing the spring, the member 6a is reinstated and the arm 8 withdrawn ; the whole pile then falling on to the member 6a ready for the succeeding operation. The appliance is held in the hand and moved over the cake so that the lower end of the tube is at the point at which the decoration is to be applied.

A given volume of pressurised liquid in a sealed enclosure is degassed by cooling a proportion of the liquid at the upper part of the enclosure in a first step, then all of the liquid is cooled in a second step, so as to reduce the volume occupied by the liquid and create a zone at lower pressure in which zone the liberated gas collects. In the drawing, tubular member 1 is formed by parts 3, 2 each associated with an independent cooling circuit, and has internal cooling element 29 along its axis. Liquid filling chamber 13 is first cooled by a flow of coolant through helical groove 17, then an abrupt cooling of the whole of the liquid is effected by a flow of coolant through helical ducts 20, 21 and coil 26. The liquid contracts and liberated gases collect at the top of chamber 13. Insulating sheath 29 contains thermocouples to measure the temperature of the liquid; its pressure may be measured by a device connected at 12. There is reference to analysis of the gases evolved by burning them, when appropriate, using heating plug 30 at the top of chamber 13, and measuring the change in gas pressure on combustion.

Abstract: 1,091,333. Rotary hydraulic motors and pumps. H. TEVES, E.A. TEVES and M. TAUSEND [trading as ALFRED TEVES MASCHINEN-UND ARMATUREN FABRIK KOMM GES]. Jan. 14, 1965 [Jan. 24, 1964], No. 1669/65. Heading F1F. A rotary hydraulic-machine of the outwardlysliding radial-vane type that is capable of operating as either a motor or a pump comprises a casing containing a rotor 9 carrying a plurality of vanes 8 that are pressed against a cam-ring 10 by springs 13 lodged in axial bores or chambers 20, said cam-ring being a part of said casing and situated between check-plates 5, 11 that together with end covers 1, 6 define annular inlet and outlet chambers 4, 17 for working fluid e. g. oil. In operation of the machine as a motor, two pumps 3a, 3b deliver oil to spaces or compartments 12 between the vanes through a conduit 2, the chamber 4 and reniform apertures 7 and, simultaneously, to the chambers 20 that are associated with unretracted vanes through a plurality of conduits 15 and bores 14 so as to press the said vanes against the camring. Oil is ejected from the compartments 12 into a reservoir 23 when the compartment comes into register with further reniform apertures 16 that are connected to the reservoir by the chamber 17 and a conduit 18 containing two-way valve 22, oil being simultaneously ejected from the chambers 20 associated with vanes undergoing retraction through a plurality of bores 25, conduits 19 and a non-return valve 21 in the conduit 18. When the valve 22 is reversed, the conduit 18 is closed and oil leaving the pump 3a flows directly into the reservoir 23, whereas oil leaving the pump 3b closes a non-return valve 24 to prevent oil entering the conduits 15 and produces sufficient pressure in the compartments 12 to effect retraction of every vane on the rotor against the action of the springs 13 as well as radial-acceleration forces acting on the vanes, thereby rendering the apertures 7, 16 in direct connection with one another and the rotor capable of rotating freely without production of useful torque. It is stated that such operation of the machine is desirable when the machine operates as a motor in the driving mechanism of a motor vehicle during periods when the vehicle is travelling down a long gradient, thereby obviating excessive rotor speeds. A pressure-relief valve 27 for the conduit 18 is connected to the reservoir. The valve 22 may be operated in response to pressure or speed changes. It is further stated that the vanes 8 may be replaced by balls.
