Title: Improvements in or relating to stop devices for controllable pitch propellers
IPC: B64C11/38
Filed: 1947-03-03
Abstract: 636,402. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. March 3, 1947, No. 5973. Convention date, April 17, 1946. [Class 114] A pitch stop device for a hydraulically operated propeller is moved to its inactive position hydraulically. The pitch - changing piston 32 carries with it the sleeve 66 until its surface 94 engages the stops 68. To proceed past this limiting position hydraulic fluid at higher pressure than the normal operating pressure is led through the line 46 to unseat valve 100 and thus to move piston 90 to the right. A wedge block 84 is thus moved from between the stop hooks, and these are then pressed inward by the surface 94. The operative position of the stops is adjusted by screwing sleeve 38 into or out of the sleeve 70. In modifications the stops are attached to and adjusted relative to the dome 36 or the stops engage the sleeve 38 on its movement to the left. Specifications 505,077, 505,168, 505,169, 514,725 and 607,856 are referred to.

Title: Improvements relating to the preparation of histamine and its derivatives
IPC: C07D233/84
Filed: 1934-02-23
Abstract: Histamine (4(5)-b -aminoethylglyoxaline) and its derivatives substituted by one or two alkyl groups on the nitrogen atom of the amino group, and quaternary ammonium salts derived from such N-dialkylhistamines, are prepared from 4(5)-b -hydroxyethylglyoxaline by reacting this with thionyl chloride to yield 4(5)-b -chlorethylglyoxaline hydrochloride, and reacting the latter with ammonia or an alkyl amine.  When a primary alkyl amine is used, it may be taken in the form of its p-toluenesulphonyl derivative, in which event the reaction product is saponified to remove the p-toluenesulphonyl group.  Examples are given in which 4(5)-b -chlorethylglyoxaline hydrochloride is reacted with (1) methylamine, (2) p-toluenesulphomethylamide, (3) ammonia, (4) trimethylamine, (5) dimethylamine and (6) ethylamine; example 1 gives details of the recovery of the base as its dipicrate, and the conversion of the latter into the dihydrochloride; in example 2, the reaction product is hydrolyzed with dilute sulphuric acid to remove the p-toluenesulphonyl group, the final product being identical with that of example 1 (4(5)-b -methylaminoethylglyoxaline hydrochloride); the product of example 4 is a quaternary ammonium salt (4(5)-b -trimethylaminoethylglyoxaline chloride hydrochloride).  4(5)-b -Hydroxyethylglyoxaline is obtainable as follows.  A salt of a -aminobutyrolactone is reduced with sodium amalgam to yield a salt of a -amino-g -hydroxybutyraldehyde; the latter reacts with ammonium thiocyanate to yield 2-thiol-4(5) - b  - hydroxyethylglyoxaline, from which 4(5)-b -hydroxyethylglyoxaline is obtainable by oxidation with dilute nitric acid.  The Provisional Specification refers to an alternative method in which ethyl g -phenoxy-a -aminobutyrate hydrochloride is reduced with sodium amalgam to yield g -phenoxy-a -aminobutyraldehyde, which is reacted with ammonium thiocyanate to form 2-thiol-4(5)-b -phenoxyethylglyoxaline; the latter is oxidized to yield 4(5)-b -phenoxyethylglyoxaline, from which the required product is obtained by dearylation.

Filed: 1917-05-02
Abstract: 114,507. ChanÚ, M. May 2, 1917. Addition to 109,242. Driving-arrangements. - In apparatus of the kind described in the parent Specification, in which the automatic re-engagement of the clutchactuating lever 1 is controlled as described in Specification 113,004, by the movement of the belt-fork rod, the spring 2 controlling the lever 1 is secured to a second lever 3 mounted on the same pivot 4. The release of the catch 21, 22 by the rise of the ring rail allows the lever 1 to turn and bring the stop 13 against the projection 14 on the lever 3. The lever 3 is locked doubly by a catch 6 on a bell-crank 7, 8 and by a stop 16 on the belt-fork rod 17. The belt-fork rod also carries a projection 15, adapted when the belt is moved on to the loose pulley to engage the stop 20 and tilt the bell-crank 7, 8, releasing the catch 6. The movement of the rod 17 also carries the stop 16. out of the way of the projection 18 on the lever 3. The release of the catch 6 allows the spring 10 to throw the lever 3 over to actuate suddenly, through the engagement of the parts 14, 13, the clutch-actuating lever 1. The return movement of the belt fork restores the lever 3 to its original position through the engagement of the parts 16, 18, and allows the spring 24 to turn the bell-crank 7, 8 and re-engage the catch 6.

Title: Improvements in or relating to drill assemblies
IPC: E21B17/04
Filed: 1955-03-03
Abstract: The socket wall of a metal rock drill bit or the socket-engaging surface of the shank has chemically bonded thereto a thin crystalline coherent lubricant coating of a metallic salt. The coating, which is corrosion-resistant, is formed from phosphate, chromate or oxalate solutions and has self lubrication properties to an extent to protect the metal parts but to an extent insufficient to cause slipping or breakdown of the press fit between the shank and the socket during the drilling operation.  The coating solution may consist of 250 parts zinc oxide; 600 parts sodium nitrate; 750 parts nitric acid 42 DEG Be; 900 parts zinc dihydrogen phosphate and 2,500 parts water Using 70 pounds of the above solution in 750 pounds of water the drill bit body is immersed in this diluted solution for from 1 to 5 minutes at temperatures within the range of 160-200 DEG F.  Other dihydrogen phosphates may be used, such as the corresponding salts of cadmium, calcium, strontium, barium, chromium and manganese.  A small amount of copper salt added to the bath tends to reduce the processing time.  With ferrous metals coatings of iron phosphates and/or complexes thereof and salts of oxalic acid are preferred.

Abstract: 426,289. Packeting-machines ; making packets. PRIOR, A. C., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Feb. 27, 1934, No. 6326. [Classes 18 and 94 (i)] Relates to a machine such as that described in Specification 302,814, [Class 94 (i)], in which two packets are secured together by flaps at their open ends to produce a double packet. According to the invention, a succession of packets is fed along the bed of the machine, resting on the faces to which the closure flaps are applied, and each successive pair of packets is closed one upon the other, so that they may be secured together to form a double packet. Packets 1 are fed, four at a time, to a magazine 7, the superposed pile being normally supported by members 8 intermittently withdrawn by cams 9. A pusher 10 on a chain 11 moves the lowermost packet to the left, Fig. 1, beneath a brush 14, and the next packet is similarly moved into engagement with it so that the two packets are in the positions a, a<1>. Members 15 on bell-crank levers 16, engage the underside of the leading packet and raise it into the position shown in Fig. 5. The rear packet is engaged by a pusher 12, and its movement to the left causes the raised packet to overbalance and fall upon it, having been rotated about its rear edge half a revolution. The packets are aligned by the action of a brush 21 into the position shown in Fig. 7, and are now ready to be joined by uniting the closure flaps 5. In another method of operation, each packet may be rotated through a right angle about its abutting edge.

Title: A Supporting Device for Hats.
Inventor: HASTIE WILLIAM
IPC: A42B1/24
Filed: 1917-05-04
Abstract: 111,429. Hastie, W. May 4, 1917. Attachments for supporting. - A hat is provided with a device to enable it to be placed on the ground or other surface without actual contact therewith, and thereby prevented from becoming soiled. It consists essentially of three or more supporting pins G which may be projected through the top of the hat shown in Fig. 3, or withdrawn within the hat. To the centre of the interior of the top of the hat is attached by internal .and external screwed washers T, Y, Fig. 4, a hollow spindle A within which slides a rod B having a stop C thereon and a knob L at its extremity. The spindle is provided with a helical slot or groove D, while outside it slides a hollow sleeve E having a horizontal slot H and three or more arms F, each ending in a pin G which can pass through an opening K in the top of the hat. When it is required to place the hat on the ground, the rod B is raised, and finally turned so that the stop enters the upper horizontal part M of the slot. By this means, the sleeve is also raised and the pins projected through the hat as shown. In modifications the rod is omitted. In one, the sleeve carries a ferrule to which the stop is attached, while the slot in the spindle is straight with lateral extensions at each end. The sleeve is raised and lowered by means of the ferrule. In another modification, a spring catch is fixed to the interior of the spindle, and engages in vertical slots in the spindle and in the sliding sleeve. In a third modification, the pins form the extremities of levers, the shorter inner ends of which are caused to move down or up, to project or retract the pins, by turning the sleeve, which is provided with cam slots, while the hollow spindle is provided with vertical slots.

Title: Improvements in chart recording apparatus for use with automatic continuous weighing and measuring machines
IPC: G01G23/18
Filed: 1936-03-03
Abstract: 471,251. Weighing and recording apparatus. BROWN, S. C. March 3, 1936, No. 6382. [Class 143] [Also in Group XIX] In a recording-apparatus for use with an automatic continuous weighing-machine wherein a graph of the load carried on a conveyer band is made on a chart rotated independently of the conveyer, means are provided for vibrating the pen or marker continuously and rapidly so as to break contact intermittently with the chart and thus eliminate errors due to frictional resistance. As shown in Figs. 1 and 2, a weighing idler 1 over which the top strand 2 of the conveyer runs, is connected by a rod 3 to a weighbeam 4 fitted with a dashpot 5 and pendulum weight 6. The weighbeam carries a flexible pointer 7a by means of an arm 7 limited in movement by stops 8a and carrying an adjustable balance weight 8. The pointer carries a marker which is normally held out of contact with the chart 7b by the flexibility of the pointer but is vibrated into repeated contact with the chart by means of a rod 10 carried by a lever 11 oscillated by a cam 12, flexible shaft 13 and wheel 14 bearing upon the under strand 2a of the conveyer. The vibration minimizes friction between the marker and the chart. In order to ensure that the marker shall be out of contact with the rotating chart and thus cease to make a record when the conveyer stops, an arm 11b of the lever 11 is pressed by a spring against a second cam 16 on the shaft 13 so that in the event of the marker being held against the chart by the cam 12 when the conveyer stops, the pressure of the arm 11b on its cam gives the shaft 13 a further rotation to withdraw the marker. An ink ribbon 18 mav be interposed between the marker and the chart. In a modification, Fig. 4 (not shown), the flexible pointer 7a is arranged at rightangles to the supporting arm 7 so that the pen moves in a straight line (instead of an arc) up and down the chart. In a further modification, Fig. 5, the flexible pointer 7a is vibrated by vertical rods 24 moved to-and-fro by a cam 22 and bell-crank lever 11. The cam is pivotally mounted on a shaft 21 driven by the conveyer and tends to assume a tilted position (shown by broken lines) under the influence of a spring 23. When the cam is rotating, centrifugal force causes it to assume the horizontal position and oscillate the pen. If the conveyer stops, thus stopping the vibration, the cam assumes the tilted position and presents a concentric path to the bell-crank lever thereby moving the pen from the chart. In a further modification, Figs. 7, 8 (not shown), the pen arm is mounted on a slide oscillated bv an eccentric driven from the convever. In a further modification, Fig. 9 (not shown), the vibration of the pen is effected by a make-and-break trembler energized from the conveyer-driving circuit or by a dynamo driven by the conveyer. When the conveyer stops, an over-weighted lever normally rendered inoperative by an electromagnet is released to push the marker off the chart.

Abstract: 1, 026, 591. Filters for liquids; adsorbent filter. R. H. EATON-WILLIAMS and D. A. G. MARSHALL. May 21, 1962, No. 6481/61.. Headings B1D and B1L. A filter element for purifying liquids or for removing noxious vapours and odours from gases, e.g. air, comprises a substantially flat spiral of strip material 1, the turns of the spiral being spaced to define flow-passages 5 which are open at both faces of the spiral, and granules 2 of filter media in the spaces between the turns, the media being stuck to the strip material. The granules may be applied to the strip material by spraying them on to a wet or tacky adhesive coating on the material or by passing the coated material through a container filled with granules. The granules may be stuck to one or both faces of the strip material. One end of the strip material is thereafter stuck to a wood core 3 and the strip wound upon itself to form the spiral which is sealed around its circumference by length of tape 4. In an example a cellulose adhesive strip is passed from a spool over a roller and then into a container filled with active carbon granules, the strip passing under a roller in the container and then out of the latter between two rollers which remove any free carbon. The tape end is thereafter fixed to a wooden core located against a wooden disc rotated by a geared driving device. The size of the element is given as 12 ins. diameter by 5/8 ins. thick and it is stated to pass 150 cubic feet of air per minute with a resistance of 0. inch water gauge whilst exposing a total projected area of approximately 10 square feet of carbon-coated surface to the air. The element may be covered on one or both sides with mesh material and/or the surfaces of the element may be lightly sprayed with hot lacquer. Square or rectangular elements may be made by first making a circular element and then shaping this by pushing it into a frame. The strip material may be, alternatively, of vinyl sheet or paper and the adhesive may be permanently tacky or of a type which sets soon after the granules are applied to it.
