[Also in Division A3] Cellular polyurethanes having a density in excess of 10 pounds per cubic foot are prepared by reacting in a one-step process (a) a polyisocyanate component comprising methylene bis- (phenyl isocyanate), (b) a polyol component which is a polyester diol of equivalent weight from 75 to 1700 or a polyether polyol of equivalent weight from 300 to 1600 and an average functionality of 2 to 4, or a mixture thereof and (c) a blowing agent which is (i) up to 0À5% by weight based on the weight of component (6) of water and/or (ii) one or more aliphatic halogenated hydrocarbons having a b.p. not more than 110‹ C., the ratio of isocyanate groups to active hydrogen in the reaction components, including the water when used as a blowing agent, being in the range of 0À95:1À0 to 1À2:1À0. Suitably, the polyisocyanate component (c) comprises a mixture of polymethylene polyphenyl isocyanates containing from 35 to 85% by weight of methylene bis-(phenyl isocyanate) or comprises methylene bis-(phenyl isocyanate) which has previously been heated at 160‹ to 250‹ C. in the presence of 0À1 to 3% of a trialkylphosphate until the isocyanate equivalent is from 130 to 150. The reaction mixture may also contain a component (d) which is an aromatic primary diamine wherein each of the amino groups is attached directly to an aromatic nucleus, e.g. 3,3<SP>1</SP>-dichlorobenzidine, and/or an aliphatic hydrocarbon diol containing 1 to 6 carbon atoms. Aliphatic halogenated hydrocarbons are suitably used as the blowing agent (ii). Conventional catalysts, surfactants and plasticizers may be added to the reaction mixture. The compositions may be poured into moulds to prepare shoe soles and heels, pouredin-place gaskets for the air filter case of an automobile engine or spring pads.

Abstract: 1329452 Regulating fluid-flow VOLVO FLYGMOTOR AB 4 Dec 1970 [4 Dec 1969 3 Dec 1970] 57662/70 Heading G3H A load-insensitive fluid amplifier incorporates a flap member 1 pivoted about an axis 2, the flap being disposed downstream of the control passages S 1 , S 2  and being shaped to conform closely to the arcuate surface 3 at the intersection of the amplifier outlet passages. In the state of the flap shown, fluid from the input 'i' flows in its entirety to the active outlet 'a' whilst return flow within the passive passage 'p' is inhibited from mixing with the supply fluid by the flap 3. The amplifier may have a drain passage disposed intermediate the outlet passages in which case the flap downstream side is made convex such that any return flow within the passive passage may communicate with the drain passage, Fig.2 (not shown). In other modification, Figs.3-9 (not shown), the single flap may be replaced by two flaps, or the flap may be formed with a channel by means of which a given outlet passage may be brought into communication with an intermediate drain passage. Also in the case of single flap having a concave downstream face, the flap terminal portions may be made resilient. The amplifier may be connected to the opposite ends of a piston and cylinder.

Title: Dc dynamoelectric machine control circuits
IPC: B60L7/12
Filed: 1972-12-19
Abstract: 1415178 Control of DC motors; battery charging systems GENERAL ELECTRIC CO 19 Dec 1972 [29 Dec 1971] 58540/72 Headings H2J and H2H A shunt field motor 11 of an electric vehicle is energized from a battery comprising two sections 15, 17 in series, through a conventional thyristor chopper circuit 27 controlled by an accelerator when contacts 21, 25a are closed, and when the motor regenerates its output is used to charge one section of the battery at a time, whereby alternate periods of motor driving and braking produce alternate charging of the sections to charge the whole battery over a period of time. During motor driving a resistor 23 is biased by a spring to establish a constant field current, the resistor being adjusted by a brake pedal to increase the field current to produce regnerative braking. A switching circuit, including a bi-stable multivibrator 47, and two monostable multivibrators 41, 43 changes the operation from drive to regeneration or vice-versa and each time it switches to regeneration a different section of the battery is selected for charging by operation of relay 39 under control of the bi-stable multivibrator. In one condition of the bi-stable, relay 39 is energized, contacts 39a, 39b are closed and relay 31 is energized, closing contact 31a allowing oneshot circuit 41 to trigger thyristor 33 to charge section 17 of the battery. When the bi-stable is in its other state relays 39 and 19 are deenergized allowing one-shot circuit 43 to be supplied through normally closed contacts 19c, 31b and hence to trigger thyristor 37 to charge section 15 of the battery.
