Abstract: 915,008. Jointing. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT. Aug. 24, 1959 [Aug. 26, 1958], No. 28869/59. Class 83 (4). A process for the bonding of metals using known synthetic resin adhesives is characterized in that the parts to be bonded are heated to a temperature of 50‹ to 250‹ C. for a period of from 10 seconds to 5 minutes to produce a high initial bonding strength. Heat-curing or cold-curing types of adhesives are used for example (a) unsaturated polyester resins, monomeric acrylic or methacrylic acid esters, styrene and polyvinyl ethers, or (b) polystyrene with monomeric methyl methacrylate, or (c) polystyrene, monomeric methyl methacrylate, unsaturated polyester resins and minor amounts of polychloroprene, or (d) polystyrene, styrene and acrylic acid, or (e) adhesives based on epoxide resins. The heat treatment temperature is produced by high-frequency welding equipment of known type and is applied for approximately 3 minutes when using a heatcuring adhesive and approximately 10 seconds for a cold-curing adhesive. In an example, strips of anticorodal are cemented together and immediately introduced into a drying chamber for 1 minute at 80‹ C. and then allowed to cool for 4 minutes. Other examples of joining strips of Bondur and copper are disclosed in the Specification.

Title: Improvements in and relating to radio direction or position finding
IPC: G01S1/02
Filed: 1937-10-22
Abstract: 504,293. Directive wireless systems. THOMAS, H. A. Oct. 22, 1937, No. 28921. [Class 40 (v)] To ascertain both the direction and elevation of an aeroplane in flight, or of a meteorological balloon, two vertical aerials, such as 1, 1a of an Adcock pair, are spaced apart by more than the work ing wavelength, and are continuously rotated on bearings 9, 10. The aerial voltage is fed to a common receiver 5 through transmis. sion lines 2, 2a of equal length, and the critical minima readings are recorded by a relay and stylus 15 on a synchronously-rotated scale 14. The aerial voltages are either added or subtracted, according to the position of a reversing switch 3. The arrangement gives several minima, both in azimuth and elevation, and the relative angular positions of these are used to determine the elevation of the craft. For a four-metre wave, the aerial spacing is 20 feet, and the whole structure can be mounted around one central shaft, though for longer waves up to 10 metres a turntable is used. The speed of rotation is 30 revolutions per minute or less. In a typical case, six minima are obtained : two in azimuth, when the plane of the aerials is normal to that containing the incident wave ; and four in elevation, when the projection of the aerial-spacing along the direction of the wave is equal to one wavelength. An aerial spacing of 1¢ wavelengths gives the best allround results, because. although the accuracy in elevation is somewhat less than that given by a wavelength spacing, the minima are sharper, and the range of elevation is increased Voltage subtraction is used for angles of elevation up to 40‹, and voltage addition beyond that angle up to 70‹. A typical record taken on a flat-paper scale by a spirally-moving marker is shown in Fig. 8 (Prov.). It is assumed that the azimuth angle is 243‹ and the elevation 35‹. The numbered ticks represent timing marks. The cluster of ticks between 242 and 260‹, and between 62 and 85‹ represents azimuth bearings, with voltage subtraction, from time 1 ... 4, the corresponding elevation ticks lying between 298 and 332‹; 8 to 12‹ ; 118 to 152‹ ; and 188 to 192‹. The reversing switch is operated, to add the aerial voltages, for the higher angles of elevation shown. The aerial system should be sited over an earth of homogeneous conductivity, preferably above a large screen. The Provisional Specification also includes graphs showing the variation of signal intensity with angular rotation as given by voltage addition and subtraction respectively; graphs indicating the accuracy of elevational readings and the effect of frequency changes upon them ; and a detailed description of the theory underlying the invention.

Title: Production of lactams by rearrangement of cyclic ketoximes
Inventor: IRNICH RUDOLF
IPC: C07D201/04
Filed: 1963-07-23
Abstract: A lactam is produced by treating a solid cycloalkanone oxime at 210-450 DEG  C. with an acid catalyst in a fluidized bed, the oxime being a solid and being introduced in a current of inert gas. Cycloalkanone oximes specified have 5-12 carbon atoms, e.g. cyclopentanone, cyclohexanone, methylcyclopentanone, methylcyclohexanone, cyclooctanone and cyclodecanone oximes. The reaction pressure may be atmospheric or above or below atmospheric. The catalyst, e.g. phosphoric acid, boric acid, or a Li, Na or K hydrogen sulphate may be mixed with a solid carrier, e.g. an oxide of an element in the 3rd or 4th group of the periodic table, e.g. Al, Si, Sn or Ti or pumice, activated charcoal or ZnO.  The catalyst and carrier may be mixed with water, extruded into rods or pellets, dried at 120 DEG  C. and further heated to 400-800 DEG  C. The catalyst carrier ratio may vary from 1: 0.25 to 1:100.  Inert gases specified are N2, CO2 and argon.  2-3 1. may be required per gram ketoxime. The catalyst and oxime may be supplied through a single metering device.  The heat liberated during the reaction is sufficient to evaporate the oxime and the reaction zone may in fact be cooled.  The volatile reaction products may be passed through a cyclone to separate out catalyst particles.  The majority of lactam may then be condensed at 60-80 DEG  C. the remainder being washed out with water. The uncondensed gases may be returned to the fluidized bed.  The product may be purified by distillation under reduced pressure optionally with the addition of oleum, treatment with KMnO4, filtration and redistillation.  In Example (1) the catalyst is boric oxide.  In Example (2) the catalyst is used boric oxide recycled from Example 1.

Abstract: 888,203. Making reinforcing rods; altering physical structure. HUFNAGL, W. Aug. 25, 1959, No. 29071/59. Addition to 818,833. Classes 83 (2) and 83 (4). In a modification or improvement of the process for the production of high tensile steel rods or wires for reinforcing concrete from steel rods or wires of lower tensile strength as disclosed in the parent Specification, the process consists of two stages in the first of which the rods are pulled by a first tensile force through a drawing die, and the second of which includes a step in which the rods are profiled by being pulled through a rolling mill by a tensile force that is substantially less than the first. The profiling may be carried out in several steps, using a three high-rolling mill. In an example, a rod of 5.5 mms. is drawn down to 4.3 mms., using a force of between 312 and 467 kg., depending on the speed of drawing. The rod is passed through profiling rolls to reduce its diameter to 4.2 mms. The tensile force used in this stage is about 75 kg.

Abstract: 897,886. Angular bending. HILGERS MASCHINEN-UND APPARATE BAUANSTALT. Sept. 11, 1958 [Sept. 12, 1957], No. 29170/58. Addition to 875,428. Class 83 (4). Means for feeding a tube to a bending- machine which includes a rotary former to which the tube is clamped and around which it is bent and a mandrel for supporting the unbent trailing part of the tube comprises apparatus movable to a position in line with the mandrel so that a tube may, by pusher means, be pushed over the mandrel, the apparatus being then moved back out of range of a free tube end projecting from the bending means and is characterized in that a device is moved under a tube supply container to push the bottom layer or layers of tubes an amount such that the appropriate number of tubes to be bent simultaneously by the bender, e.g. two, are fed to the pusher means. The bottom layer of tubes 11 from a container 10, partitioned at 21, is supported on a guideway 17 and is moved therealong by a slide 12, slightly concave at its end 18 and bevelled at the top near the sides so that a number of tubes, two when the apparatus to which the tubes are ultimately fed bends two tubes simultaneously, are pushed past a curved deflector 22 to drop into a U-guide 23 then positioned therebelow. The guide 23 is then moved, by hydraulic means 26 acting through rods 29, to the position shown in Fig. 3 in which the tubes are in line with the appropriate parts of the bending apparatus, bars 29 extending rearwardly of the guide 23 closing the opening between the guides 17 and 22. When the guide 23 reaches this outer or transfer position a slide 15 is moved forward to pass between the two tubes in the guide 23 to give them a correct vertical spacing. A piston then pushes the tubes endwise from the guide 23 to the bending apparatus. Two layers of tubes may be pushed from the container 10.

Title: Improvements in or relating to position control systems
Inventor: WOOD PETER
IPC: B21B37/60
Filed: 1956-09-24
Abstract: 840,551. Electric correspondence control systems. GENERAL ELECTRIC CO. Ltd. Sept. 24, 1957 [Sept. 24, 1956], No. 29176/56. Class 40 (1). Apparatus for controlling, e.g., the screwdown motors of a rolling mill comprises coarse and fine balancing bridges, the coarse bridge having relays in the unbalance diagonal which reduce the speed of the motors as balance is approached and then transfers control of the motors to the fine bridge, whose unbalance current is biased by tachogenerators to avoid hunting. As shown (Fig. 1) the coarse bridge consists of a transmitter potentiometer 5, which is preset to the integral part of the required dimension, and a balancing potentiometer 6 driven by the motors. The unbalance diagonal contains a first slow-down relay 9, which is deenergized at a predetermined minimum unbalance current to reduce the motor speed by increasing the field current, a second slow-down relay 10, which further reduces the motor speed by adding resistance in the armature circuit, and a polarized relay 11 which at balance transfers control of the motors to the fine bridge by closing contacts 24 (Fig. 2). The fine bridge consists of a transmitter potentiometer 7, which is preset to the fractional part of the required dimension, and a balancing potentiometer 8. The unbalance diagonal includes the control winding 13 of a magnetic amplifier 12, whose output winding controls the screwdown motor speed. The combined output of two tachogenerators 28, 29 is fed through a resistance network 30 with a second control winding 31 of the magnetic amplifier 12 in opposition to control winding 13, to prevent hunting. The setting of the fine transmitter potentiometer also controls the value of a bias to be introduced into the coarse bridge, which is removed on transfer to the fine bridge, so that final adjustment is always made on potentiometer 8. The apparatus may be duplicated and relay controlled to provide a series of consecutive displacements of different values.
