Title: Process for the production of coloured synthetic resins
IPC: C08J3/21
Filed: 1958-09-23
Abstract: A hardenable condensation product of an aldehyde with a compound of urea-like character is coloured with a dyestuff containing at least one acid group imparting solubility in water and at least one group containing at least one labile hydrogen atom and the coloured product is subjected to a condensation treatment.  Suitable compounds of urea-like character are urea, thiourea, guanidine, acetylene diurea, dicyandiamide, uron, melamine, and aceto-, benzo- or formo-guanamine. The aldehyde condensate of the urea-like compound may be partially etherified, e.g. with methanol.  Particularly suitable dyestuffs contain a group of formula: <FORM:0874369/IV (a)/1> wherein n is a whole number less than 5 and Z is amino, substituted amino, a substituted hydroxyl or mercapto group or a chlorine atom.  The dyestuffs may be oxazine, triphenylmethane, xanthene, nitro, perinone, azo, anthraquinone or phthalocyanine dyestuffs.  They are applied from aqueous solution if desired with an acid-binding agent. In Examples (1), (4) a dyestuff of formula: <FORM:0874369/IV (a)/2> p is added with sodium chloride to aqueous hexamethylol melamine, the mixture rendered alkaline and after 2 hours filtered and the red powder obtained is washed and dried.  It is dissolved in aqueous alkali, acidified and filtered off as a polycondensate.  A coloured polycondensate is similarly obtained from (2) aqueous dimethylol urea; (3) aqueous trimethylol melamine; (5) aqueous hexamethylol mealmine with a different dyestuff.  The coloured polycondensates are suitable for manufacture of shaped structures or for colour pigments.

Abstract: 306,017. Wessel, H. Nov. 14, 1927. Locking nuts. - For locking nuts and bolts grooves or recesses are provided in the nut and the bolt and the locking member is shaped so that when inserted it cannot move laterally and upon a change of shape is prevented from being withdrawn longitudinally. The nut b, Fig. 1, is cut away so as to have an internal conical surface g and the bolt a is cut across to provide a shoulder f. The locking member is formed of soft material which after being inserted is deformed so that it is unable to move in either direction. In the modification the nut has open sided slots and the free ends of the inserted member h, Fig. 3, are bent back to engage a groove formed in the outer face of the nut. According to a further modification the end of the bolt has a hole i, Fig. 4, and the locking member h extends radially on either side thereof. In other modifications the bolt has cross slots and the nut in addition to slots has an enlarged space i, Fig. 5. In this case the locking member h is in two strips and is similarly bent over at the ends. When the locking member is in two parts these may be arranged in slots at right angles and have central interlocking slots to prevent lateral displacement.

Title: Process for the production of tubular articles of iron, steel or metallic alloys
IPC: B21K5/06
Filed: 1932-10-31
Abstract: 407,444. Making tubular articles. KLUGER, L., 9 Loblichgasse, Vienna. Oct. 31, 1932, No. 30745. [Classes 83 (ii) and 83 (iv).] Cased or compound forms; cores and fillings; working at specified temperatures.-In a process for the production of tubular articles such as hollow drills tubes gunbarrels &c., of iron, steel, or metallic alloys, wherein a core is inserted in a pierced and heated blank the core material has a greater coefficient of expansion than the blank and a melting point not less than 1100‹ C., the core diameter at the moment of insertion into the hot blank being substantially as large as or larger than the hole in the blank and the blank and inserted core being then heated together to the temperature required for shaping by rolling or forging. In this way a high interior pressure is exerted and maintained on the blank during the shaping operation. The difference between the temperature t, of the blank and the lower temperature t<2> of the core may be varied between wide limits. Core materials should be of great strength and durability such as sustenitic manganese steels, chrome nickel steels &c. The core or blank may be coated with graphite or the like to prevent welding together of the core and blank. The blank temperature is above 300‹ C. but is preferably near the rolling temperature, i.e. between 900‹ and 1100‹ C. and the core may be at or below room temperature or may be slightly heated. If the core is of larger diameter than the hole in the blank it may be assembled by mechanical pressure and by tapering the end of the core. In some cases a mandrel may be first employed to pierce the heated blank, and the mandrel then replaced by a cold core. Prior to inserting the core a tubular lining capable of welding with the blank may be inserted in the blank, the liner being preferably at room temperature and having a diameter corresponding to the internal diameter of the heated blank. Anticorrosive coatings may also be provided. In one example the blank steel suitable for rock drills contains 0.7 to 0.8 per cent C, 0.25 to 0.35 per cent. Mn, 0.25 per cent Si and not more than 0.05 per cent of P and S together. The steel billet 60-80 cms. in length and 100 mm. diameter has a hole 30 mm in diameter and is heated slowly to 800-900‹ C. and then a cold core having a diameter exceeding that of the bore in the cold blank by about 0.2 mm and coated with graphite is inserted in the bore. The blank and core are then reheated to 900‹ C. and subsequently rolled. In some cases a core 31 mm in diameter is driven into the blank by a hammer or press. Tubular liners having corrosion resisting or other special properties may be heated and a cold graphited core drawn into the liner tube. The core and liner are then cooled and inserted into a heated blank having a hole preferably smaller than the core with its surrounding liner. Instead of drawing a liner on to the core the core may be coated with metal or alloy by spraying or dipping.

Abstract: 342,262. Centrifugal governors. JUNKERS, H., 21, Kaiserplatz, Dessau, Anhalt, Germany. Oct. 15, 1929, No. 31302. Convention date, Nov. 3, 1928. [Class 57.] Centrifugal governors for controlling the fue supply to Diesel engines are constructed so that the degree of irregu larity (that is, the amount by which the engine speed when idling and when under full load varies from the working speed for which the governor is set) increases considerably when the governor is set for low speeds. This is effected by designing the governor so that the ratio of the radial distances of the governor bobs from the axis for idling and full load respectively is at least equal to 1 : 4. In the form shown, the governor balls 3 are free to move redially between a flat disc 4 and a conical disc 5, which is subjected to the pressure of a spring 7 and connected by a lever 15 to an adjusting member on the fuel pump. The spring 7 is adjusted by a screw 10 actuated by a rack and pinion 12, 13.

Abstract: 1302301 Inductive vehicle guidance systems EATON CORP 29 June 1970 [7 July 1969] 31336/70 Heading H4U A vehicle guidance system, particularly applicable to automatic warehouse trucks, comprises a rectangular grid of guidance wires and means on the vehicles for following a wire and counting its intersections with other wires until at a predetermined count the vehicle is caused to make an in-place turn on to a new guidance wire. As shown truck 10 has inductive pick-ups 30, 32 left and right of the followed wire which carries an A.C. signal. When the induced signals depart from equality the front wheels are turned via 38, 40, 42, 22 and 20 which operates an hydraulic cylinder 18. The signals from further inductors 50 are added and counted at 58 to control either the turning onto a new guidance line or the stopping of the truck at its destination under control of the program selector 60. Turning is effected by stopping the truck before applying the appropriate left-orright turn signal to relay 42. The truck is stopped with sensors 50 immediately over the intersecting wire which is to be the new guidance wire, and in the turn operation the front wheels are turned through 90 degrees until the induced signals in coils 50 reach a new peak, as detected by a peak detector circuit (Fig. 1B, not shown). The guidance wires are connected in series in two sets, and in order to prevent local magnetic field distortion at the intersections disturbing the guidance along a wire, the sets may be supplied with A.C. signals which are 90 degrees out of phase.

[Classes 106 (i) and 106 (iii)] A counting apparatus for summing positive and negative units, such as passengers ascending to and descending from the upper deck of a bus, comprises a number indicator (13), two electromagnets (C, D) adapted to operate the indicator step-by-step in opposite directions, two main switch devices (A, B) associated one with each electromagnet and spaced apart along the path of the units to be counted (e.g. disposed on adjacent stairs) so as to be operated in succession, two relays (R(xyz), S(xyz)), each in circuit with its main switch device and operating switches (Rx, Ry or Sx, Sy) to close a circuit from its main switch device to its associated electromagnet, and to open the circuit of the other relay, and means for resetting all the switches after both main switch devices have been operated in succession. Where switch A is closed before switch B, current passes from supply at P<SP>2</SP> through relay R(xyz) to P<SP>1</SP>, and the energized relay closes switch Rx to prepare a circuit for the indicator electromagnet D which operates when the switch B is subsequently closed. The opening of contacts Ry prevents energization of the relay S(xyz). Closure of contacts Rz establishes a holding circuit for the relay R(xyz) which is maintained until, upon the return of the actuating pawl (18 in this case), a switch P interconnected therewith is momentarily opened and the switches &c. are restored to their initial positions. Instead of the holding circuits and switches P, Q, a time-delay device may be associated with each relay R(xyz), S(xyz). In addition to the normal indications observable through an aperture 11, a switch 21 operated by a cam portion 22 on the indicator drum illuminates a warning light 20 when the maximum capacity is reached. The counter provides for a few additional units to be added when this condition applies. Additional switches E, F enable corrections to be made where necessary. Photo-electric cells may be employed to close the switches A, B.
