Title: Organic titanium complex and method of making same
IPC: D06M13/207
Filed: 1956-11-27
Abstract: A stable water-soluble titanium lactate complex salt of an organic nitrogenous base is obtained by a modification of the method for producing a water-soluble titanium lactate complex according to the parent Specification consisting in the adjustment of the pH of the resulting water-soluble acidic titanium lactate complex by adding an organic nitrogenous base. Suitable bases are amines, such as ethylamine, and aminoalcohols such as ethanolamine, triethanolamine, b -aminoethylethanolamine, diisopropanolamine and ethylethanolamine. The products are useful in textile applications.  In examples: (1) titanyl sulphate is added with stirring to calcium lactate and calcium hydroxide and after standing overnight the mixture is filtered and washed, the filtrate and washings comprising an acidic titanium dilactate complex solution; the pH of this solution is raised from 1.7 to 6 by adding ethanolamine and the solution is evaporated to dryness; (2) an acidic titanium monolactate complex solution is prepared by a method similar to (1) using one half the stoichiometric amount of calcium lactate and the pH is raised from 1.6 to 3 by adding triethanolamine; (3) an acidic titanium monolactate complex is formed by adding titanyl sulphate to lactic acid and barium carbonate and after filtration the pH of the filtrate is raised from 1.5 to 8 by adding b -aminoethylethanolamine; (4) an acidic titanium dilactate complex solution is prepared from titanyl sulphate, lactic acid and strontium carbonate and the pH of the resulting solution is adjusted to 8.0 by addition of diisopropanolamine; (5) the procedure of (2) is repeated using calcium oxide in place of the hydroxide and the pH of the resulting acidic complex is adjusted to 7 by addition of N-ethylethanolamine; (6) the procedure of (2) is repeated except that the pH of the acid complex is raised to 7 by addition of triethylamine.

Title: Device for the step by step feed of a strip in a wrapping machine
IPC: B65B41/18
Filed: 1953-12-31
Abstract: 729,728. Photo-electric control of web feeding. SAPAL, SOC. ANON. DES PLIEUSES AUTOMATIQUES. Dec. 31, 1953 [Jan. 8, 1953], No. 36331/53. Class 40 (3). In a device for feeding strip periodically, the strip is given a constant amplitude feed and a variable amplitude correcting movement which is imparted by a correcting apparatus having a reciprocating movement and which grips the strip at a point in the reciprocation when a datum mark on the strip is detected by a photo-electric code carried by the correcting apparatus. As shown, the constant amplitude feed is given to the strip by jaws 6 which grip the strip periodically and draw it from a drum 3 over a spring tensioned roller 4. The correcting movement is imparted to the strip by a reciprocating mechanism 8 which includes a photo-electric cell 9, light source 10, solenoid 13 and plunger 16. An eccentric 23 and bell-crank lever 24 reciprocate this mechanism on, a guide 18 and a cam 37 periodically closes a switch 34. In operation, with the jaws 6 open, the correcting mechanism 8 commences to move to the right. When a datum mark on the strip is illuminated by source 10, photo-electric cell 9 receives reflected light and energizes solenoids 13 and 30 connected in series with each other and with camoperated switch 34 now closed. Solenoid 13 presses plunger 16 into contact with the strip which it then carries backwards with the correcting head while solenoid 30 removes a gripping member 26 from the strip allowing the feed-back to be taken up by the spring-loaded jockey arm 4. When the correcting head completes its movement to the right, cam 37 opens switch 34 releasing the solenoid gripper 16 and holding the strip by solenoid actuated member 26. Jaws 6 then grip the material and a rod 33 releases member 26, the strip then being drawn to the left a fixed amount and sheared immediately afterwards. If a double strip is used the bed of the machine may be slotted, so that member 16 is able to clamp the strips together against a member which moves with the correcting head.

IPC: F16H61/662
Filed: 1967-08-10
Abstract: 1,200,668. Controlling expanding wheel gearing and clutches. REIMERS GETRIEBE A. G. 10 Aug., 1967, No. 36680/67. Headings F2C, F2D and F2L. In a continuously variable ratio expanding pulley gear, one half 72, 75 of each pulley is axially movable and has an hydraulic cylinder associated therewith, the cylinder pressures being regulated by valves 25, 34 to maintain a selected ratio and to apply by hydraulic pres-  sure alone a gripping force on the torque transmitting endless belt 86 connecting the pulleys which is proportional to the load on the gear. The spool 26 of valve 25 is pivoted to a floating lever 29 connected at one end to a ratio selector 31 or to an input driven centrifugal governor, and at the other end to a circumferential groove in the pulley half 72 to provide a servo feedback. The valve 25 controls the distribution of pressure fluid between lines 23, 24 leading to the pulley halves 72, 75 to maintain a selected ratio and to regulate the pressure in the cylinder of the driving pulley in proportion to the load on that pulley. Valve 34 regulates the pressure in the cylinder of the driven pulley in proportion to the pressure in the cylinder of the driving pulley, being biased by the latter pressure. To allow for torque reversal on overrun, &c., a valve 39 with a free piston 40 connects valve 34 to the cylinder of whichever pulley is driving. Pressure fluid is supplied to a line 28 by a pump 91 driven by a gear 92 on the input shaft 70, or from a central pressure source. Excess fluid passes via a line 37 and the valve 34 to a sump or to lubricate the belt 86. In each pulley, the halves are freely rotatable on their shaft and are connected for rotation together by toothed sleeves 76, 77. Hydraulically engaged friction clutches 80, 81 connect the movable halves 72, 75 to their shafts and one-way clutches 89, 90 connect the axially fixed halves 71, 74 to their shafts. The one-way clutches are arranged so that whichever direction the torque is in, the driving pulley is connected to its shaft by the friction clutch and the driven pulley is connected to its shaft by the one-way clutch. The areas of the clutch applying pistons 87, 88 are such that on overload, the friction clutches slip at a lower torque than that which can be transmitted between the belt and the pulleys. Springs 84, 85 provide an initial grip between the belt and the pulleys. Since the clutch-applying pressure is derived from the input driven pump 91, the clutch is engaged progressively on starting. In Fig. 2 (not shown) an orifice (56) is included between the pulley cylinder and the chitch cylinder to enhance the progressive action. The Fig. 2 embodiment does not cater for reverse torque, so that the one way clutches and valve 39 are omitted, and a friction clutch is used on the driving pulley only. The Fig. 1, embodiment has no clutches, but includes the valve 39 to cater for torque reversals. In Figs. 1, 2 (not shown) the pulley halves are keyed directly to their shafts.

Filed: 1955-12-22
Abstract: 805,791. Starting prime movers. S.U. CARBURETTER CO. Ltd. March 22, 1956 [Dec. 22, 1955], No. 36735/55. Class 38 (4). A cold starting device for an internal combustion engine comprises an auxiliary fuel inlet valve which is opened to allow additional fuel to enter the engine during the starting period. An auxiliary fuel inlet valve 5 is normally maintained against its seating 4 by a spring 6. A solenoid 11 is energized simultaneously with the energization of a starter motor for the engine, energization of the solenoid causing a plunger 9 to move downwardly thereby opening the auxiliary fuel inlet valve 5 by means of a pushrod 7. During the starting period, therefore, fuel is able to enter a chamber 2 from a fuel pump by way of an inlet 20 through a tubular member 3 past the valve 5 and push-rod 7, the fuel passing from the chamber 2 to the engine throttle by way of spill outlets 21, 22, 23 and an orifice 24, the fuel entering the engine from the chamber 2 being additional to that which enters the engine by normal means. During the starting period a small air flow is induced into the chamber 2 from the atmosphere by way of gravity controlled valve 27 and an inlet 26. If desired, a thermo-sensitive device may be incorporated to preclude the operation of the cold starting device when the ambient temperature renders its use unnecessary.

Abstract: 620,613. Testing physical qualities of materials. DEHN, S. G. (Dillon & Co., Inc., W. C.). Dec. 17, 1946, No. 37140. [Class 106 (ii)] In a testing-machine in which a load is applied to an element slidable in a frame, and the element is connected to a dynamometer or other indicating device, a nut is threaded on the element and bears against the frame and is so biassed that as the element moves in response to the load the nut is turned and maintains its contact with the frame, thus preventing rapid return of the element when the specimen snaps. The load-carrying element 22 is attached to a specimen grip 32 and to a movable stud 36 of the dynamometer and slides in a hole in a platen 16. A steel nut 40 having a bronze insert is threaded on the element 22 and bears against a thrust bearing 44, 46. A cable 58 wound round the drum passes over a pulley 62 and has a weight 64 on the end. As the load is applied by turning a handle 20, the nut 40 tends to move downwards, but the turning action of the weight 64 and cable 58 causes it to rotate and move up the element to maintain contact with the bearing. Thus, when the specimen snaps, the element does not fly back, but can be returned to its zero position manually by means of a handle 5, 4 and openings 52.
