Abstract: 292,912. Scovill Manufacturing Co., (Assignees of Belfit, R. W.). June 25, 1927, [Convention date]. Urea-aldehyde condensation products.-Relates to compositions comprising a condensation product of a compound having a plurality of nitrogen atoms bonded to a carbon atom, at least one of which is an amino-nitrogen, and a hydroxy-aromatic acid, or a derivative containing a hydroxy aromatic group. Suitable nitrogen-containing compounds are urea, thiourea, or their derivatives, such as benzoyl- or acetyl-carbamide, cyanamide, guanidine, or their active derivatives &c. and suitable, hydroxy-aromatic acids or derivatives include the following substances : - salicylic acid, acetylsalicylic acid, salicylamide, the salicylates of ammonium, strontium, or magnesium, gallic acid, hydronaphthoic acids, and hydroxy-benzoic acids. Such additions preferably comprise at least 15 per cent of the nitrogen body. The compositions, produced in the form of solutions provide improved lacquers. Thus urea may be condensed with formaldehyde or its polymers in aqueous solution, and adding thereto the resistivity agent such as salicylic acid dissolved in an organic solvent mixture comprising a low boiling solvent such as ethyl alcohol, a medium boiling solvent such as butyl alcohol, and a high boiling solvent such as ethyl lactate. The solvents may be added to the urea and formaldehyde condensation product solution and the hydroxyaromatic acid &c. then added, or the acid may be present before condensation, and the solvents added afterwards. Other organic solvents such as normal- or iso-propyl alcohol, acetone, ethylene glycol monoethyl ether, isobutyl alcohol, benzene, butyl acetate, alcohol, &c. may be used. Plasticizers such as castor oil, oleic acid, mastic, natural rosins &c. may be incorporated in the lacquers which are hardened after application by heat, e.g. at 130-150‹ C. Further condensation is stated to occur during the baking operation. The lacquers may be compounded with cellulose lacquers and natural resins &c. Pigments, organic colours, fillers and waxes may be added. A potentially reactive phenolic condensation product may be mixed with the urea-formaldehydesalicylic acid product and the mixture hardened under heat and pressure. Examples with proportions are given. The Specification as open to inspection under Sect. 91 (3) (a) describes the use of benzoic, phthalic and anthranilic acids, and aliphatic dibasic acids, such as succinic and oxalic acids as suitable additions in place of the hydroxy-aromatic acid or derivatives referred to above, and also the use of petroleum, coal tar hydrocarbons, terpenes and hydrocarbou chlorides as solvents. This subject-matter does not appear in the Specification as accepted.

Filed: 1955-06-21
Abstract: 773,258. Photographic shutters. VEB ZEISS IKON DRESDEN. June 21, 1955 No. 17910/55. Class 98(1) In a photographic multiple-blade shutter having blades oscillated for effecting exposure by two blade-driving rings, the rings are released consecutively from their set positions and the time interval between the release of the two.rings is determined by control means provided with its own force-storing means and delayed by retarding mechanism, the control means causing the second ring to run off after the control means has been released as a result of the running off movement of the first ring. As shown, the blades 6 are pivoted at 12 and 13 on the rings 1 and 2 urged clockwise by springs 4 and 5. The setting lever 3 rotates the ring 1 anticlockwise until the lug 16 thereon is eiigaged by the trigger 11, and the nose 15 on the ring 1 engages the lug 14 on the ring 2 to rotate the ring 2 until the lug 14 is engaged by the pawl 10. At the same time, the pin 17 on the ring 1 rotates the control member 7 clockwise against its spring 8. The toothed segment 18 of the retarding escapement is urged towards operative position by the spring 21, and a pin 19 thereon engages a setting cam 20. When the trigger 11 is operated the ring 1 rotates to open the shutter blades, and the consequential movement of the control means 7 is retarded by the engagement of the lug 9 with the toothed segment 18. After a time controlled by the position of the cam 20, the pin 22 on the control means 7 engages the arm 23 of the pawl 10 and releases the ring 2 to rotate to close the shutter. With a non-setting shutter, the member 3 may disengage from the ring 1 at the appropriate point.

An hydraulic system comprises hydraulic means 10 coupling the output of a free piston internal combustion engine 1 to a fluid motor 2, and means 12 operative on the hydraulic means for controlling the output of the motor. The engine has opposed pistons 40 having plungers which pump fluid 13 in chambers 24, connected by conduits 8 to the outlet 5 from the motor 2, past valves 25 consisting of flexible metal strips into chambers 28 connected by conduits 10 to the inlet 4 of the motor. The pressure in the conduits 8 is maintained at a low value by an accumulator 9 and the pressure in the conduits 10 is controlled by a chamber 12 which can be connected to a source 15 of gas under pressure or to atmosphere 17 by operation of valves 16, 19. With valve 19 closed and valve 16 opened, the pressure is maintained in the conduits 10 for maximum transmission of power. Reversing the valve 16, 19 reduces the pressure in the conduits 10 so that the speed of the output shaft 3 of the motor is zero. The valves 16, 19 may be coupled together for simultaneous operation and one of the valves may be replaced by a small orifice. Ihe engine is started by an explosion, such as gunpowder, which is contained in a receptacle 73 opening, by means of a nozzle 73 into a combustion chamber 11, the explosive being set off by, for example, percussion means. During reciprocation of the pistons, an outlet port 20 is uncovered to permit the gases in the chamber to drive a turbine 31 before passing to an outlet 38, the turbine driving a compressor 32 to pass air from an inlet 37 to an inlet port 21. A passage 58 is uncovered during the strokes of the piston to connect the pressure in the chamber 11 to the interior of a bellows 56 which is also connected to atmosphere through a port 62. The bellows is connected by a link 59 to a fuel meterinjector 60 joined by a conduit 43 to a fuel source 66 and by a conduit 44 to an injector nozzle 65. The strokes of the pistons are maintained constant by vents 51 and orifices 52 connected to a source of pressure 75. Specification 1,003,602 is referred to.
