Filed: 1920-05-26
Abstract: 160,381. Ochsenhirt, R. May 26, 1920. No Patent granted (Sealing fee not paid). Darning.- The material to be darned is stretched over a block A and is held by a frame B, the sides of which have spring clips b fitting grooves in the sides of the block. The warp threads are fastened in the material and stretched between rotatable hooks n carried by a carrier C and fixed hooks q on a carrier D. The carriers are pivoted, to allow of their being turned up to free the hooks of the warp threads, in spring- pieces m which are attached by spring plates to L-shaped clamps e sliding in guide slots in the frame sides and having inwardly projecting lugs g adapted to engage holes h in the frame sides, whereby the carriers may be adjusted and fixed at any desired distance apart. In a modification, Fig. 5, the frame and spring clips are replaced by bar r having circular or spiral grooves and held in contact with the grooved sides of the block A by springs t. The carriers C, D are pivoted to cranks of shafts 1 mounted in bridges u which are provided with spring clamps w adapted to engage the grooves in the bars r. In Fig. 5, the carriers are shown turned up in position to permit the warp threads to be removed from the hooks. A darning-needle is used to pass the weft thread through the warps and insert it in the material.

Title: Improvements in and connected with epicyclic gear control for motor vehicles and the like
IPC: G05G13/00
Filed: 1922-05-23
Abstract: 199,234. Hounsfield, L. H. May 23, 1922. Controlling variable-speed gearing. -Selector mechanism especially for epicyclic variable-speed gearing is arranged so that the depression of a pedal A releases the brake or clutch in action and disconnects the drive. For each brake &c. operating device P there is a short lever G in one of the slots H of a gate, which short lever carries a rocking lever J upon a pivot K. Each device P is connected by a rod O to its own rocking lever, and all the rocking levers are linked to the pedal A. Each rocking lever has a spring S, which coacts with stops Q, R. To bring, say, the top speed into action, the pedal is depressed, and all the levers G move in their slots, the stops Q being engaged. The springs S yield and no brake &c. is supplied. A loose hand-lever E is thrust into the slot of the speed selected and locked there by a pawl V. On release of the pedal, the selected short lever G is held while the others return to neutral, the spring S of the selected lever device asserts itself, and the brake &c. is applied, too fierce application being prevented by a stop R. Depression of the pedal reverses the last operation and disconnects the drive. The reverse gear is preferably operated by a link connected directly to the lever E, which is then moved in the opposite direction. In a two-speed gear, the lowspeed may be brought into operation by the hand lever E acting against a short lever such as G connected directly by a link to the brake-applying device. Release of such a device by depressing the pedal A is assured by forming the upper end G<1> of the lever G of the high-speed as a cam adapted to disengage the pawl V from its catch W<1> on the gate.

Title: Means to prevent inward leakage across seals in a housing
IPC: E21B47/18
Filed: 1972-03-29
Abstract: 1374678 Shaft seals MOBIL OIL CORP 29 March 1972 [20 May 1971] 14778/72 Heading F2B [Also in Division E1] A tool 46 positioned in a flowing stream of fluid comprises a housing 46a having a compartment 62 filled with incompressible fluid, a rotary shaft 51 protruding through the housing from the compartment, a seal 60 surrounding the shaft where it leaves the housing, and means for applying a greater pressure to the seal from the compartment than from outside the housing. The tool 46 comprises a "logging-while-drilling" tool and is installed in a drill collar 26 in the path of the mud flow to the bit. A transducer such as a strain gauge 47, senses the down-hole weight on the bit and sends an electrical signal to a control circuit sealed in a compartment 48. The circuit allows current from a generator 49 to drive a motor 50 at a speed determined by the electrical signal. The motor drives a rotary valve 52 to give pressure pulses in the mud which are sensed at the surface, the frequency of the pulses depending on the magnitude of the downhole weight. The generator 49 is rotated by a mud driven turbine comprising a stator 58 fixed to the tool body and a rotor 59 mounted on a shaft 56. The rotary valve has a stator 54 fixed to body of the tool and a rotor 55 driven from the motor 50 by gearing 53 and the shaft 51. The generator 49 and the motor-gearing combination 50, 53 are respectively housed in oil filled compartments 63, 62, seals 61, 60 being provided about the shafts 56; 51. The mud flows through the rotary valve, the annulus 70, and the turbine. The seal 60 comprises a tungsten carbide block 60a turning with the rotor 55 and a block 60b urged by a spring 78 into contact with the block 60a. The compartment 62 includes bellows 64 subjected to mud pressure P, os that the pressure P 2  in the interior of the compartment 62 and on the seal is approximately equal to P 1 . The pressure drop in the mud over the rotor 55 results in a pressure P 3 , less than the pressure P 2 , being applied to the exterior of the housing so that any leakage at the seal is outward and mud will not leak into the tool. The seal 61 has tungsten carbide and graphite blocks, pressure is applied to the compartment 63 by mud acting on a flexible diaphragm 65, and the pressure drop is caused by the stator 58.

Filed: 1933-05-23
Abstract: 421,641. Magnetic tests. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of I. G. Farbenindustrie Akt.-Ges. ; Frankfort-on-Main, Germany) May 23, 1933, No. 14879. Convention date, May 23, 1932. [Class 37] In order to test materials for flaws by examining the normal components of a magnetic field set up at non-uniform points, a coil mounted in a plane parallel to the surface of the test piece is caused to oscillate in its own plane and is connected to head phones or a loud-speaker so that changes in the normal magnetic components are detected. A test piece W containing a weld R to be examined is magnetized by two bar magnets T, T1 excited by alternating or direct current. The upper ends of the cores of the magnets T, T1 are formed with large iron surfaces so as to lead the stray field outwards. A search coil S is mounted so as to vibrate in a plane parallel to the plane of the test piece and is connected through an amplifier V to headphones K. The coil S is vibrated by mechanical connection to the reed of a loudspeaker, the exciting coil E of which is connected through an amplifier U to a pick-up N, the needle of which contacts with an electromagnet excited by alternating current, so that the coil S is vibrated at the frequency of the supply. The currents or sounds received at the headphones K may be back-coupled electrically or acoustically with the primary oscillation circuit of the coil E or with the oscillating member of the coil S. The pick-up N may alternatively run on a recording disc of constant frequency. In a modification, the coil S is mounted on a vibrating metal spiral such as the first or second inner turn of a clock gong, which is set in oscillation by striking. Alternatively the coil may be fixed to the end of a tuning fork which is struck by a clock mechanism every 1 to 5 seconds. Specifications 153,748 and 296,303, [both in Class 37], are referred to. The Specification as open to inspection under Sect. 91 states also that the coil S may be held fast against the point to be examined, an iron core being vibrated axially. The core may be of a material having high initial permeability and a high demagnetizing factor, such as iron carbonyl powder. This subjectmatter does not appear in the Specification as accepted.

Title: A process for the treatment of the residuary ammonium chloride lyes derived from the manufacture of sodium carbonate by the ammonia process
IPC: C01D7/18
Filed: 1921-05-28
Abstract: Residual liquor from the ammonia-soda process containing principally ammonium chloride and carbonates and sodium chloride, is heated to near its boiling point until all the carbonate and free carbon-dioxide are evolved.  The ammonium carbonate or mixture of carbonate and bicarbonate is collected in the solid condition; preferably carbon dioxide is introduced if necessary so that all the ammonium is in the form of bicarbonate.  The liquor is concentrated to one-third to two-thirds its volume and cooled to below 25 DEG  C. when technically pure ammonium chloride crystals are obtained.  After filtration, the mother-liquor is again concentrated at its boiling point to one-third to two-thirds its volume, in order to separate sodium chloride.  The latter is removed as nearly as possible at 110 DEG  C., the boiling point of the solution.  The liquor now contains ammonium chloride and sodium chloride in approximately the same proportion as the original solution, and may be treated as above described, but preferably fresh residual liquor is first added.  The ammonium chloride contains only small quantities of sodium chloride and may be purified by re-crystallization or sublimation.ALSO:Residual liquor from the ammonia-soda process containing principally ammonium chloride and carbonate and sodium chloride is heated to near its boiling-point until all the ammonium carbonate and free carbon-dioxide are evolved.
