Title: Shuttles for pneumatic shuttle-conveying systems
IPC: B65G51/06
Filed: 1974-04-23
Abstract: 1474936 Pneumatic shuttle conveyer SIEMENS AG 23 April 1974 [2 May 1973] 17612/74 Heading B8A A shuttle for a pneumatic shuttle conveyer system with travel tubes having a circular cross section, has an arcuately waisted central zone and two outer zones in the form of an arcuate convex surface of revolution referred to the longitudinal axis of the shuttle. In the figure, the shape of the shuttle is defined by heavy lines and can be seen to be the common area of the projections of tube bends R1, R2. The central zone contacts the inner surface of a bend when the shuttle is being conveyed, while the outer surface is contracted by the end portions. When the shuttle travels along straight portions the transitional zones between the central zone and the two end portions contact the wall of the tube, as shown at RO.

Title: Improved process for making very strong viscose filaments
IPC: D01F2/06
Filed: 1939-06-16
Abstract: 530,129. Artificial silk &c. VEREINIGTE GLANZSTOFF-FABRIKEN AKT.-GES. June 16, 1939, No. 17685. Convention date, June 16, 1938. [Class 2 (ii)] Strong filaments are obtained from viscose by extruding the viscose into an acid primary bath containing iron sulphate, and then subjecting the filaments to a high degree of stretch-, ing in a hot secondary bath, the temperature of which is above 60C. Viscose is spun into a bath containing per litre 125 grams H 2 SO 4 , 260 grams Na 2 SO 4 , and 50 grams FeSO 4 . The filaments are passed to a secondary bath heated to 85C. and stretched by means of rollers. The secondary bath may contain the same ingredients as the first bath but in more diluted form, and these ingredients may be introduced into the secondary bath by the filaments themselves which carry them from the first bath. The temperature of the secondary bath may be as high as the boiling temperature of the water in the bath. The primary bath may be heated, e.g. to 50C. Substantially no clogging of the spinning orifices occurs when using ferrous sulphate in the primary bath. Specification 467,500 is referred to.

Title: Improved apparatus for the heat-treatment of wax and wax mixtures
IPC: C10G73/36
Filed: 1934-06-15
Abstract: An apparatus for sweating waxes or for crystallizing waxes from solutions containing them, consists of a chamber A to contain the wax, provided with small diameter pipes B through which a heating or cooling liquid passes, said pipes being provided with fins, gills or other heat-conducting projections C.  The chamber A is surrounded by a cooling jacket E, in which are mounted pipes G, H connected by headers D to the pipes B.  The pipes B may be arranged in staggered formation or the pipes in one row may cross those in adjacent rows. The pipes are also mounted closer together at the bottom of the vessel <PICT:0437053/III/1> than at the top.  The fins C may consist of a series of plates p  threaded close together over each pipe, or may extend as a wall across the vessel and have perforations through which the pipes pass.  Distancing pieces maintain the fins in position.  The lower edges of the fins mounted on the lowermost series of pipes are fluted, notched or serrated whereby the oil removed by sweating is permitted to flow over the sloping floor to the outlet O.  Heating during the sweating stage may be controlled thermostatically and after a short time heat may be cut off from the upper coils.  The apparatus may be used for separating wax from oil by dissolving the oil in benzol and cooling the solution in the sweating chamber.  The mother liquor is drawn off from the resulting wax crystals which are then washed with solvent and melted out. Specification 243,447, [Class 91], is referred to.

Filed: 1926-07-16
Abstract: 266,201. Burman, E. July 16, 1926. Counter-scales and the like.-In a semi-automatic weighing-device of the kind wherein the weighing capacity is increased by the addition of loose weights to the weights pan and wherein the weights pan is movable vertically relative to its support upon the beam so as automatically to indicate the amount of the added weights, the indication is effected through a parallelogram construction connected to a rotatable member actuated by the relative movement between the weights pan and its support. The depending leg j of the weights pan b passes freely through a cylindrical casing supported by a knife-edge h on the weigh beam c. The usual check arm q steadies the casing. A pin l on the leg rests on a spring h or on a pendulum-weight lever. The lower end of the leg carries a rod n coupled by a link o to a disc p mounted on knife-edges on the cylindrical casing f. The disc p is further connected by a link s to an indicating pointer r pivoted coaxially with the fulcrum of the beam When loose weights are placed upon the pan b the pointer r indicates their amount on a graduated scale x arranged adjacent the usual scale u provided in connection with the usual pendulum pointer v. Owing to the parallelogram arrangement of the link s in connection with the knife-edges of the beam the indications of the pointer r are unaffected by the position assumed by the goods pan a.

Title: Improvements in time controlled maximum demand contactor devices
IPC: G01R11/60
Filed: 1946-06-17
Abstract: 613,571. Supply meters. LANDIS & GYR SOC. ANON. June 17, 1946, No. 18186. Convention date, June 26, 1945. [Class 37] [Also in Group XXXVII] A contactor for a maximum demand indicator has a pair of normally-closed contacts 14, 15, on contact arms 12, 13, the front edges of which bear on the surface 11 of a release lever 10, one edge being slightly in advance of the other. The release lever 10 is pivoted at 8 and carries a pin 7 which is engaged by a lifting lever 6, rotated by the hour shaft 1 of a time mechanism through a gear train. A cam 16 driven directly by the shaft 1 engages a pin 17 on a lever 20 pivoted at 18, whereby a pin 21 restores the arms 12, 13. As the shaft 1 rotates from the position shown the contact arms 12, 13 fall in quick succession from the surface 11 causing the contacts 14, 15 to be momentarily broken, whereby the pointer of the maximum demand indicator is returned to the zero position. The circuit cannot again be affected until the cam 16 causes the pin 21 to raise the contact arms 12, 13, allowing the lever 10 to return by a spring 9 beneath them. The frequency of operation of the contactor can be altered by varying the number of arms of the cam 16 but this will not affect the contactor operating time. The lever 6 may have a single arm and the gear ratio be doubled. Alternatively, a pair of contacts 23, 24, which are momentarily connected together may be used in place of the opening contacts 14, 15.

Title: Means for studying air-flow
IPC: G01M9/06
Filed: 1943-11-12
Abstract: 579,681. Testing aircraft. GRAY, W. E. Nov. 12, 1943, No. 18810. [Class 4] In order to study the airflow over an aeroplane part, such as a wing, it is coated with a thin layer of starch mixed with potassium iodide with or without a small quantity of glycerine, and the part is then subjected in a wind tunnel or during free flight to the action of chlorine or ozone released into the airstream some distance ahead, the resulting differences in the degree of colouration indicating the areas of transition from laminar to turbulent flow. Smoke may be mixed with, or discharged in close proximity to the chemical gas to render it visible. A photographic record may be made of the colouration for comparison with others. Alternatively, a coating may be used which shows the action of the chemical gases only after further treatment. In the wind tunnel shown, the chemical gases are introduced through a tube 5 at a point where the wind velocity is relatively low and at. a sufficient distance from the part 4 to be tested to enable the disturbance of the airflow caused by such introduction to die down before reaching the test specimen. For testing in free flight, the gases are discharged from an aeroplane flying some distance in front of the craft being tested or they may, be released from a shell-like contamer fired up to or dropped to the test level where it bursts. Sodium thiosulphate may be added to the starch coating to prevent gradual discolouration when flying before and after the test. According to the Provisional Specification, a thin coating of lead acetate may be applied to the wing and subjected to the action of sulphuretted hydrogen.
