Title: Improvements in or relating to rotary power conversion machines of the rotary abutment type
IPC: F02B75/28
Filed: 1947-07-31
Abstract: 625,625. Rotary engines. BERRY, F. July 31, 1947, No. 20771. Convention date, April 23, 1940. [Class 110(ii)] An engine of the rotary abutment type has a rotor 11 provided with axial extensions 20 in recesses 21, a piston 15 on a hump-piece with cammed ends 35, 36, and a n abutment rotor 12 provided with inlet and outlet ports 41, 42 which connect with conduits 39, 40 (not shown) respectively, in end plates 25, 26 to supply compressed gas to the working chamber 24. Compressed gas trapped in a recess 31, in the abutment, passes back to the chamber 24 through a by-pass 44. An outlet pipe 45, near the exhaust end of 24, enables fresh air which rushes into the chamber 24 on the first opening of the exhaust port to pass up into a collector 46 past a check valve 47. A by-pass 48 (not shown) in the cylinder side wall extends from the abutment to beyond the air outlet 45 to allow burnt gases behind the piston to exhaust through recess 49 and ports 42, 40. As the piston uncovers pipe 45, the compressed air in pipe 45 expands back into the working chamber and scavenges it. Air ahead of the piston 15 may be discharged through a recess 50 in the abutment and may be used as charging air for the engine-coolant flow through the rotor, abutment and casing. For the rotor, inlet and outlet conduits 51, 52 are provided in the rotor shaft which connect with chambers 53, 54. A pump 55 may be used to force coolant through the rotor. The abutment shaft 28 has inlet and outlet conduits 56, 57 for cooling fluid which forces over fins 58 in the abutment. A pump 59 and a collecting chamber 60 may be provided. One coolant circulating system may be used for abutment and rotor. Fig. 8 shows a modified engine using steam or compressed air having an intake 62 and an exhaust 63. An alternative inlet 64 may be used for a continuous supply of fluid.

Title: Improvements relating to cranes
IPC: B66C23/10
Filed: 1927-08-09
Abstract: 300,228. Evans, W. E., (Demag Akt.-Ges.). Aug. 9,1927. Jib cranes.-Horizontal movement of the load in luffing is ensured by passing the load rope 11 over a pulley 10 carried on a member 7 pivoted to the frame at 8 and guided by rollers 6 running on a curved track on the jib. A balance weight 12 for the jib is carried on the guide member 7, and as shown in Fig. 1 may be on the axis of the rollers 6. The weight is always to the right of the line A, B and tends to prevent overturning. In a modification, Fig. 2, the load rope 11 passes round a sheave 3 on the jib-foot pivot and thence to the compensating pulley 10. The balance weight 12 is movable along the member 7, being suspended by a rope 26 attached to the jib at 28 or to the frame at 3 and passing over a pulley 27. The track for the counterweight 12 on the member 7 may be curved. In another modification, the balance weight is carried by a separate radius rod and is guided by a separate cam surface on the jib, and exact balance can then be obtained. As shown in Fig. 4, the luffing motor 14 drives a countershaft 20 on the pivoted member 7 of the compensating gear, and the countershaft drives a pinion 23 engaging a rack 24 upon the jib. In a modification of this arrangement, the luffing motor is mounted on the member 7, and the counterweight is moved along the member 7 by a screw-thread on the countershaft.

Filed: 1976-05-21
Abstract: 1520846 Polyisocyanate compositions IMPERIAL CHEMICAL INDUSTRIES Ltd 7 April 1977 [21 May 1976] 21061/76 Heading C3R A polyisocyanate composition is manufactured by a process which comprises reacting at least 4 molar proportions of tolylene diisocyanate with 1 molar proportion of an oxypropylated triol of molecular weight 200 to 800 in the absence of an alkylating agent under reaction conditions such that further reaction, e.g. allophanate formation, takes place after the primary urethane formation at a temperature of 120‹ C. or above. Preferably 4 to 30 molar proportions of tolylene diisocyanate are used. The tolylene diisocyanate is preferably an 80 : 20 mixture of 2,4- and 2,6-tolylene diisocyanates. The preferred oxypropylated triol is oxypropylated glycerol. A stabilizing agent, preferably an acid chloride, may, be present during the reaction. The resulting polyisocyanate composition is generally a liquid and it may be blended with a mixture of methylene bridged polyphenyl polyisocyanates and/or tolylene diisocyanate and can be used in the manufacture of a polyurethane foam by reacting the polyisocyanate composition with a polymer having at least two isocyanate reactive end groups, especially a polyether polyol, under conditions such that a foam-forming gas is produced. Suitable polyether polyols are polyoxypropylene and poly(oxypropylene)(oxyethylene) polyols having from 2 to 4 hydroxyl groups and preferably have molecular weights of from 1000 to 10,000. The foam-forming reaction mixture may contain conventional additives, e.g. blowing agents, catalysts, surfactants, cross-linkers orchain-lengtheners, flame-retardants and fillers. In a typical Example a liquid polyisocyanate composition prepared by reacting 10 moles of an 80/20, 2,4/2,6-tolylene diisocynate mixture with 1 mole of an oxypropylated glycerol of M.Wt. 310 in the presence of benzoyl chloride is diluted with 80/20, 2,4/2,6-tolylene diisocyanate and then blended with crude methylene bridged polyphenyl polyisocyanate and is then used to prepare a flexible polyurethane foam moulding from a formulation which additionally comprises an ethylene oxide tipped oxypropylated glycerol (M.Wt. 5300), water, triethylene diamine, dimethylamino ethanol, oxyethylated octylphenol and a polydimethyl siloxane.
