Patent GB-195926-A (GB)
Abstract: 195,926. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. :April 8, 1922, [Convention date]. Linear-dimension gauges.-A measuring device, for use inassorting tubes or bars is arranged to measure -simultaneously the diameters at both ,ends and' transfers the results to an indicator which shows both the sum and the difference, of the diameters so that the objects are gauged for both size and taper. Fig. 1 shows the machine in elevation; the beam 1, of which the ends are shown in plan in Fig. 6, has-lugs 2, 62; 3, 63; 4, 64; 5, 65 to which are pivoted measuring levers 8, 9 and pressing levers 10, 11 the measuring levers having fixed to them arms 28, 29 spring-pressed against stops 32, 33 while the pressing levers are normally spring-pressed - away from the measuring fevers by arms 18, 19 adapted to bear against stops 66, 67. In this position the 'tube 25 to be measured' can be inserted between the pressing and measuring levers, and a pedal is then operated to pull upon cables 16, 17 running over pulleys 20, 21 and attached to the levers 18, 19 so that the pressing levers are turned until their ends contact with stops 23, 24. This motion will be transmitted by the tube 25 being measured to the measuring levers 8, 9 which will be moved from their zero position distances equal to the external diameters of the tube at the points 30, 31, the movements being against the action of springs 56, 57 and each motion being in the same direction. Rods 34, 35 pivotally connected to the ends of the levers 28, 29 are pivoted on pins 36, 37 in a trapezoidal plate 38 which is pivotally connected by a pin 39, midway between the pins 36, 37, to a toothed sector 40 rotatably about an axis 41 and meshing with a pinion 42 carrying a pointer 44 moving over a scale 53. Since the motion of both measuring levers is in the same direction the movement of the pin 39 will be half the sum of these movements and the reading of the pointer 44 will be proportional to the sum of the diameters. If the diameters are unequal the plate 38 will rotate as well as move translationally, the angle of rotation . being proportional to the difference of the diameters. This movement is transmitted to a second pointer 52 moving over a centre-zero scale. 54 by a lever 46 pivoted to the plate at 45 and at 47 to an arm 48 of a toothed sector 49, Fig. 5 meshing with a pinion 50 carrying the pointer.

Abstract: 737,180. Making endless belts. UNITED STATES STEEL CORPORATION. Aug. 6, 1952 [March 13, 1952], No. 19772/52. Class 83 (2). [Also in Group XXIII] In a method of making an endless belt from a length of strip metal, the strip is passed around a pair of spacedapart horizontally arranged and aligned pulleys such as disclosed in Specification 735,561, [Group XVI], the ends of the strip are fastened together and the strip moved around the pulleys. A pair of parallel longitudinal lines are marked by a scriber held against the moving strip adjacent each edge as it passes around one of the pulleys and a transverse line adjacent each end of the strip is scribed perpendicular to the parallel lines. The strip is then sheared along the longitudinal and transversely scribed lines and its ends fastened together as by welding to form an endless belt. The shaft 6 of the pulley 2 is supported in spaced spherical bearings and is provided with an extension 8 by which it is driven by power. A pulley 48 is mounted for movement towards and away from the pulley 2 such as in the manner set forth in Specification 735,579. A scribing device 15 on the base 16 comprises a two-armed lever pivoted on bearings 24 on the member 18, one arm 26 having adjustably secured thereto a graduated bar 36 carrying a pair of adjustable holders 40 for scribers 44, the other arm 28 being provided with a handle 30. A compression spring 32 normally holds the arm 26 a short distance away from the pulley 2. The scribers 44 are lifted into engagement with the strip to be marked by lifting the handle 30. A piece of cold rolled strip S is passed around the pulleys 2, 48 and its ends held together by two strip clamps 68. The clamps are adjusted so that the vertical distance AB is the same at each edge of the strip in a plane midway between the pulleys. The strip is moved around the pulleys until it reaches a stabilized position. Two holes 70 are then punched in each end of the strip, a clamping bar 72 having four slotted openings 74 is placed over the adjacent ends of the strip and fastened thereto by U-shaped bolts 76 inserted through the registering holes 70 and slots 74, nuts 78 being threaded on to the ends .of the bolts. The strip is then rotated about the pulleys until two parallel straight lines are marked thereon. Transverse parallel lines are then scribed on each end immediately adjacent the clamp bar 72. Specifications 717,671, [Group XVI], and 709,908 also are referred to.

Title: Manufacture of new disazo-dyestuffs and new cupriferous disazo-dyestuffs
IPC: C09B35/08
Filed: 1948-07-23
Abstract: Diazo dyestuffs are manufactured by coupling a tetrazotized 4 : 41-diamino-3 : 31-dialkoxydiphenyl (in which the alkoxy groups preferably contain only a few carbon atoms) with a 1-naphtholtrisulphonic acid (e.g. the 4 : 6 : 8-or especially the 3 : 5 : 7- or 3 : 6 : 8-trisulphonic acid) and with a coupling component free from sulphonic acid groups and capable of coupling in a position vicinal to a hydroxy group (e.g. naphthols or substitution products thereof such as those containing halogen atoms, alkyl groups, alkoxy, including hydroxyethoxy, groups, -CO-alkyl or -CO-aryl residues, free or substituted amino groups, or sulphonamide groups with or without substituents at the nitrogen atom; 2 : 3-hydroxynaphthoic amides, especially arylides; 3-hydroxydiphenylene oxide, 2- or 3-hydroxycarbazole, or 2 : 4- or 4 : 6-dihydroxyquinoline or their N-substitution derivatives; acetoacetic arylides; pyrazolones; or arylides of 3-hydroxycarbazole-2-carboxylic acid, 3-hydroxydiphenylene oxide-2-carboxylic acid or 2-hydroxyanthracene-3-carboxylic acid). The couplings are preferably effected in the order stated, with the first in a weakly alkaline (e.g. alkali bicarbonate or carbonate) medium and the second in a more strongly alkaline medium (e.g. a medium alkaline to phenolphthalein or containing free alkali hydroxide), if desired at a somewhat raised temperature and/or with the addition of an agent accelerating coupling (e.g. pyridine).  The products may be converted into complex copper compounds by treating them (with or without isolation from the coupling mixture) with an agent yielding copper (e.g. a cuprous or cupric salt or especially a cuprammine complex) until the alkoxy groups have been split up (e.g. for several hours at 80-90 DEG  C.), advantageously with the addition of ammonia or organic bases (e.g. excess of the base present in the cuprammine complex if used) or other acid-binding agents.  The metal-free and the cupriferous dyestuffs are suitable for dyeing or printing animal fibres (e.g. silk, wool or leather), and especially cellulosic fibres (e.g. linen, cotton or regenerated cellulose), yielding mainly blue tints.  Those which are capable of combining with a further quantity of metal may be metallized on animal fibres.  Examples describe the preparation of dyestuffs from diamisidine and certain of the coupling components specified above, and the dyeing of cotton with the copper complex of the dyestuff 1 - naphthol - 3 : 6 : 8 - trisulphonic acid \sMdiamisidine-->2 : 3 - hydroxynaphthoic anilide.  Specification 644,883 is referred to.

Title: Improvements in the method of constructing armatures and sators for dynamo electric machines
IPC: H02K15/12
Filed: 1920-07-09
Abstract: 147,773. Apple, V. G. Dec. 30, 1916, [Convention date]. Cores; insulation.-The armature conductors and core laminµ are fixed together to form a rigid structure by the application of a cementitious insulating-fluid which is subsequently hardened by heating. The conductors 5, 6, which may be straight copper bars or of " hairpin " form, are covered for a portion of their length with absorbent material 9 and impregnated with heathardening insulation, leaving bare ends 10, 11. The ends 11 are threaded into openings in a round block 14 which rests on the ram 17 of an hydraulic press and the laminµ, either of round or segmental form, previously coated with heat-hardening insulation, are threaded over the conductors to build up the core. The ram 17 is next raised by opening the valve 25 causing the ends 10 of the conductor to enter perforations 21 in the head of the press and compressing the laminµ together, the excess of insulating-fluid filling the spaces in the core slots. Vertically hinged doors 27 are then closed round the armature structure, and heat is applied by a. burner 32, the baking being continued while the laminµ are under pressure. After removal from the press, the armature may be heated again in an oven or in a current of hot air, or by passing an electric current through the conductors.

Title: Automatic frequency control system
IPC: H03L7/04
Filed: 1955-07-08
Abstract: 783,133. Automatic frequency control systems. SPERRY RAND CORPORATION. July 8, 1955 [July 12, 1954], No. 19835/55. Class 38 (4). In an A.F.C. system for a klystron or other U.H.F. oscillator 11 to be controlled in frequency, the oscillations are mixed in a balanced waveguide mixer 19 with reference oscillations of lower frequency from an oscillator 24 frequency modulated by an oscillator 27. The sum or difference frequency from the mixer 19 is then passed through a cavity or other resonator 31 to a detector 32 to produce oscillations amplitude modulated at the fre quency of the modulating oscillator 27 and whose in-phase or anti-phase relation with the oscillator 27 compared in a phase comparator 35, preceded by a phase shifter 36 if necessary, determines the sense of any frequency drift of the oscillator 11. Accordingly the D.C. out. put of the phase comparator 35, amplified, may retroactively control the oscillator 11 as by application to its reflector electrode if a reflex klystron. The output of the detector 32 also may be rectified to disable a normally operating low-frequency sweep oscillator 37 giving a temporary frequency sweep to the oscillator 11 to bring the input to resonator 31 within its response characteristic.

IPC: B63H11/12
Filed: 1951-08-23
Abstract: 700,393. Propelling ships. ENGINEERING CORPORATION, Ltd. Aug. 23, 1951, No. 19867/51. Class 114 In a method of propelling a vessel by water reaction tubes through which water is propelled by gas pressure, the gas is produced initially in a pre-combustion chamber at a substantially constant pressure and relatively low temperature in the presence of excess air and is brought to complete combustion at substantially constant volume in a final combustion chamber opening into the reaction tube. Air is supplied continuously through a pipe 2 to a pre-combustion chamber 1, Fig. 1, and fuel is injected continuously through a nozzle 3. A rotary valve 5, driven initially by an electric motor 6 and thereafter by a screw 7, distributes the gas alternately through passages 8, containing further fuel injection nozzles 3a, to final combustion chambers 10 disposed in bodies 12 in the water tubes 9. The front portion 13 of each body slides over a tubular portion of the combustion chamber 10 containing gas outlet ports 16 and is adapted to close the inlet 15 of the water tube when the gas outlets are open. In another embodiment, Fig. 2, the water tubes 9 are spaced circumferentially on a circle. Air is supplied by a compressor 17 to the pre-combustion chamber 1 into which fuel is injected by nozzles 3 supplied by a pump 20. The combustion gas passes through a turbine 18, which drives the compressor, and an intermediate chamber 19 into a rotary final combustion chamber 10 which is common to all the water tubes. Additional fuel is injected by nozzles 3a into the chamber 10 and the gas is finally supplied by a rotary distributer 21 to each pair of opposite water tubes in succession. The distributer is driven by an electric motor through bevel gears 32. A screw 7 has its shaft 30 connected through a reduction gear 29 with the turbine 18 so as to be driven thereby. The screw which exerts an additional thrust preferably for starting may be disconnected from the turbine shaft at a given velocity and its blades may then be retracted into its hub 26, or it may be used to drive the distributer. In a further embodiment only part of the gas in the combustion chamber passes through the turbine and is then exhausted whilst the remainder passes direct to the final combustion chamber. A vessel may be propelled by four sets of propulsion units each set comprising several units arranged in series. The units are pivoted to the hull and may be reversed for driving the vessel astern.

[Also in Group VIII] A layer 1 of non-combustible material in fragmentary form and thermosetting material is interposed between two adjacent unfabricated layers 2 of wood in fragmentary form and thermosetting material and the assembly is bonded together under heat and pressure, thereby interlocking the irregular surfaces of the wood layers with the contiguous surfaces of the non-combustible layer and consolidating the board without substantial formation of hollow spaces between the layers. The wood may be in the form of wood shavings, wood wool, sawdust, fibres or chippings. The non-combustible material may be asbestos, mineral wool, slag wool or other artificial or naturally occurring inorganic substance. The thermosetting material may be a phenol-, urea- or melamineformaldehyde condensate or casein. The outer layers 2 may be covered by layers 3 of large area wood shavings 3a to give a more attractive appearance, or by layers of veneer. If desired, more than one non-combustible layer may be employed, the fragmentary wood layers and non-combustible layers alternating. In a further embodiment a non-combustible layer may form one of the outer layers of the composite board. In another embodiment the layers may be cold compacted and then superposed prior to subjecting to heat and pressure. The non- combustible material may be strewn on a sheet of paper and then placed on the fragmentary wood layer. A specific example describes the manufacture of the board according to the invention.
