IPC: B23D25/02
Filed: 1964-04-13
Abstract: 1,030,278. Shearing. F. MOELLER, and K. NEUMANN, [trading as VERWALTUNGESELLSCHAFT MOELLER & NEUMEN OFFENE HANDELGESELLSCHAFT]. April 13, 1964 [April 13, 1963], No. 15115/64. Heading B3W. In a flying shear in which the shear frame is oscillated by a crank mechanism, the crank-pin is mounted on a shoe which is radially adjustable in the crank disc and has a device for clamping the shoe in the desired position and is characterized in that the position of the crankpin is adjusted by device which is operable by a drive system including a gear-wheel carried eccentrically by the crank disc and rotating therewith, said gear-wheel being operatively connected to a further gear-wheel which is mounted to rotate freely on the crankshaft and which is adjustable relatively to the crank-shaft by means of a drive situated at a fixed location. The mechanism comprises a crank-disc 2 fixed to the frame oscillating crank-shaft 1, and having a crank-pin 3 mounted in a slide block 3a which is movable radially in a dovetail groove 2a. The crank-pin carries the eye 4a of a connecting rod transmitting the movement to the shear frame. The position of the crank-pin 3 is adjusted by a setting crank assembly 5, 6, 7 which is connected to the pin 3 by a link 8, and which is rotated through a gear train 38, 9, 10, 11, 12. The gear 12 meshes with a gear ring 13a forming part of a gear 13 which is freely rotatable on the crank-shaft 1. With the shear stationary the gear 13 is rotated by a motordriven pinion 15 to set the crank-pin 3 at the required radius. The setting is shown on an indicator coupled to a shaft 18 driven by a pinion 17 meshing with the wheel 13. When the shear is running the pinions 15 and 17 rotate idly. Crank-pin clamping means.-An extension 3b of the crank-pin 3a has mounted thereon a piston 31, locknuts 32, 33 and a spring assembly 34. A fluid cylinder 30 fits over the piston and receives pressure fluid through a flexible coupling. In the absence of fluid pressure, the spring assembly 34 acts against the locknuts 32, 33 and a flange 30a on the cylinder 30 and through a sleeve 36 which bears on the crank disc, clamps the slide block 3a against the dovetail groove 2a. When pressure fluid is admitted to the cylinder 30 the cylinder moves bodily to the left in Fig. 1, overcoming the spring force, and unclamps the crank-pin 3a.

Title: Process for the manufacture of derivatives of soap forming carboxylic acids
Filed: 1931-05-23
Abstract: Amines; ketones.--Amines are prepared by converting saturated soap-forming carboxylic acids, or mixtures thereof with other saturated carboxylic acids, into ketones and then treating the latter in the liquid phase with catalytically-activated hydrogen in the presence of ammonia or a primary amine.  The soap-forming carboxylic acids are those containing at least 8 carbon atoms derived from oils, fats and waxes, e.g. coco-nut oil acids, naphthenic acids occurring in petroleum, or the acids obtained by the oxidation of paraffin. Acetic acid, benzoic acid, and phenylacetic acid are mentioned as other saturated carboxylic acids, and methylamine, benzylamine or aniline as primary amines. For the production of the ketones, catalytic processes are preferably employed, but chemical processes are also applicable. The products are useful for the manufacture of washing agents. According to the examples, (1) a mixture of coco-nut oil acids the acetic acid is passed over a thoria or manganese catalyst and the separated higher ketones hydrogenated under pressure in ammoniacal methyl alcohol in the presence of nickel; the acetic acid may be omitted in the preparation of the ketone starting material; (2) a ketone mixture obtained by the catalytic treatment of naphthenic acid or stearine with acetic acid is converted into an amine product by the process of (1) above; (3) pentadecylphenylmethylketone, obtained from palmitic acid and phenylacetic acid, yields 1-phenyl-2-aminoheptadecane when treated with hydrogen under pressure in the presence of ammonia and nickel; (4) stearic acid and acetic acid are converted into heptadecylmethylketone and this hydrogenated under pressure with n-butylamine in the presence of nickel to give 2-n-butylamino-nonadecane; the same ketone mixture yields 2-phenylaminononadecane when the n-butylamine is replaced by aniline; (5) 18-aminopentatriacontane is prepared from stearone, obtained by the thermal decomposition of stearic acid, using hydrogen under pressure, ammonia and nickel, at ordinary temperature; (6) methylstearylketone, obtained from stearic acid and acetic acid, is converted into the corresponding amine by means of hydrogen and ammonia in the presence of platinum black, room temperature and atmospheric pressure being employed.  French Specification 529,159 is referred to.  The Provisional Specification refers also to arachis oil acids and resin acids as soap-forming carboxylic acids.

Title: Improved apparatus for indicating the air speed and direction of aircraft
IPC: B64D43/02
Filed: 1944-08-11
Abstract: 624,844. Airspeed indicators. SPERRY GYROSCOPE CO., Inc. Aug. 11, 1944, No. 15359. Convention date, Aug. 13, 1943. [Class 69 (i)] [Also in Group XXXVIII] In a rotary-winged aircraft, means are provided for measuring the cyclical variation in the air-speed of a rotating wing. As shown, the dynamic and static orifices 37, 34, of a pitot tube 31, mounted on the end of a rotating wing 32, and which is directed into the wind by a vane 46 and a rotatable mounting 44, are connected to a bellows 49 and a static chamber 48 respectively. An electromagnet 52 is connected to the bellows 49, the other end of which electromagnet is slidable within a fixed coil 57 in which voltages are induced dependent on the amplitude of the variation in air-speed and which may be measured by an A.C. voltmeter graduated in miles per hour. Since the variations in air-speed during one revolution of the wing have a definite phase relation with the direction of motion of the aircraft through the air, a signal having a fixed phase relation to the rotating wing may be compared with the phase of the induced voltage and the direction of motion obtained. An alternating voltage generated by a generator 71, driven through gears 73 and 72 from the rotor shaft 33, is compared with the phase of the voltage obtained from the coil 57 by a phase-meter 77 and a pointer may be used to indicate the direction of motion. The pitot tube may be replaced by a rotatably-mounted vane or by a resistance operated by the angle of the wing relative to a plane perpendicular to the axis of rotation, Figs. 11 and 8 (not shown). The direction of motion and air-speed may be indicated on one instrument, Fig. 4, wherein the pitot tube is replaced by a hot-wire anemometer 81, the leads from which are connected through slip-rings 89 and 91 on the rotor 86 and brushes 92 to a series circuit comprising a battery 96 and the primary coil 98 of a transformer 101, the secondary winding 125 of which is connected by slip-rings to the coil of a rotatable electromagnet 114 driven through gearing 133 and 134 by the rotor 86. A universally mounted pointer 137, having a polarized armature 135 is moved radially an amount depending on the amplitude of the variation produced by the hot-wire 81, thus indicating the air-speed, and in a direction dependent on the phase difference between these signals and the signals produced by the rotating electromagnet, thus indicating the direction of motion.

Title: Improvements in or relating to buttonhole sewing machines
IPC: D05B3/08
Filed: 1944-08-15
Abstract: 586,328. Sewing-machines. NEWTON, E. P. (International Button Hole Sewing Machine Co.). Aug. 15, 1944, No. 15561. [Class 112] Starting and stopping gear.-In a sewing- machine which stops at the end of a sewing cycle, particularly a button hole sewing machine, a clamp-operating mechanism is interconnected with the starting and stopping mechanism in such a way that when the clamp is closed the machine may either be started or remain stopped, and when the machine stops the clamp may either be opened automatically or remain closed. The mechanism, in the embodiment described, is substantially the same as that of Specification 594,528 in which a treadle-operated rock-shaft 87 has an arm 94 to move a bar 46 to the left to start the machine, this bar being held in the running position by a latch 101 until a part 118 on a transversely-reciprocating bar 110 is moved into a postion to release the latch by a dog 131 carried by the feed-nut; the buttonhole-cutter lever 61 is depressed and released by the stop mechanism, and the spring- closed clamp member 20 is operated by a lever 72 having an extension 71 for hand operation and a depending link with a latch 76 which engages a block on the tail of the cutter-lever 61 unless prevented by an arm 96 on the shaft 87. The mechanism differs from that of the Specification referred to in that the part 118 is pivoted, with a biassing spring, on the bar 110 and that the latch 76 is secured to the depending link adjustably. The initial depression of the treadle causes the arm 96 to disengage the latch 76 to allow the clamp to close, the machine being started, if desired, by further depression of the treadle. If the treadle is then fully released, the workclamp will be opened when the stop-mechanism actuates the cutter-lever 61, unless the latch 76 is raised above the block on the cutter-lever by manual clockwise movement of the lever 72; the opening of the clamp may alternatively be avoided by keeping the treadle path depressed so that the latch 76 is prevented from engaging the cutter-lever.

Abstract: 1,218,390. Bobbin changing mechanism. IVANHOE RESEARCH CORP. 1 April, 1968 No. 15611/68. Heading D1G. In a sewing machine aligned bobbin assemblies 2 from a magazine M are carried by a carrier C and transferred by a transfer device T to a bobbin holder H, the transfer device also serving to remove the empty bobbin case from the holder H. Bobbin cases are urged by a spring 12 into the concave and a sensor element 10 detects the arrival of the bobbin case in the carrier. The carrier is moved by a piston and cylinder 4 and a shutter 16 prevents further bobbin cases from being being ejected out of the magazine. When the carrier C is adjacent the holder H a piston 23 moves the hook 8 to push the bobbin case into the holder. To remove a bobbin case from the holder. When the carrier is adjacent the magazine the hook 8 is first longitudinally moved by a solenoid. The hook is then moved towards the holder H by piston 23 and the hook longitudinally retracted the grip the empty bobbin case. The hook is then moved outwardly by the piston 23 and the empty case falls out through a hole in the baseplate of the machine. The hook stays in its retracted, outward position until the carrier again moves forward. Removal of the empty bobbin cases may be assisted by air jets from tubes 27, 28. (For Figure see next page)
