Title: Improvements in or relating to machine tools having a reciprocable element controlled by a tracer control unit
IPC: B23Q35/08
Filed: 1957-01-23
Abstract: 844,305. Copying-lathes. SUNDSTRAND CORPORATION, [formerly SUNDSTRAND MACHINE TOOL CO.]. Jan. 23, 1957 [Jan. 27, 1956], No. 2426/57. Class 83 (3). A lathe &c. has a transversely - controlled copying-slide which carries an adjustable tracer control unit having biasing- means urging it in one direction, and a number of individually-operable control-devices for limiting the adjustment in opposition, the biasing-means, the controldevices being movable to a retracted inoperative position to disengage the control unit. An obliquely-arranged tool-carrying slide 22, Fig. 1, is supplied by a T-shaped guide 23, Fig. 4, on a longitudinal lathe-carriage 16. The slide 22, Fig. 1, is moved by an hydraulic piston-andcylinder 27, the piston-rod 30 of which is anchored to a bracket 31 secured to the carriage. The slide is retracted against an adjustable-stop 38. A bracket 60 is secured to the slide 22, and carries a dove-tailed slide 63 adjustable by a screw-and-nut 64, 65. An L-shaped extension is formed on the slide 63, comprising a horizontal leg 70 and a vertical leg 71 which is provided with pivots 75, 76, for a tracer control unit 40. The latter is biased by a spring 86, Fig. 1, in a clockwise direction, Fig. 2, away from a template 42, and towards a set of stops 97. These stops form part of piston-and-cylinder units 90, Fig. 4, which are adjustable by screws 94 along guideways in the leg 70. The stops 97 are set to project at different distances by a gauging-device 112, Fig. 2. The tracer control unit may thus be adjusted automatically at the end of each traverse to give a deeper cut, the control unit finally engaging a fixed stop 100 when all the stops 97 have been utilized and retracted. Tracer mechanism.-The control unit 40 has a stylus 41, Fig. 2, which engages an exchangeable templet 42 clamped to a bracket 44 secured to the lathe-bed. Fluid-pressure is supplied to the unit 40 from a pump driven by an electric motor. The unit includes a slide-valve which is normally biased by a spring to a position establishing fluid-flow to the cylinder 27 to move the tool T away from the work. A solenoid, on energization, disables the spring and enables a weaker spring to move the valve to a position where pressure-fluid is delivered to move the tool towards the work. The stylus is thus brought against the template, and on contact, reverses the movement of the toolslide. Reference has been directed by the Comptroller to Specification 803,522.
Patent GB-457719-A (GB)
Title: Improvements in or relating to methods of extracting titanium compounds from titanium-containing ore
IPC: C22B34/12
Filed: 1936-01-27
Abstract: In extracting titanium compounds from titanium ores by means of concentrated sulphuric acid, an organic compound is added to the mixed ore and acid to produce finely divided carbon which assists in retaining within the mass a substantial amount of the steam evolved during the reaction.  When treating ilmenite the mixture of ore and acid may be heated, say to 125 DEG  C. and a small amount, say 0,6 per cent by weight of the ore, of a carbohydrate such as dextrine or sugar be added to initiate the reaction, which proceeds to completion without further application of external heat.  The mass resulting from the reaction is highly porous and readily dissolved in water. The Specification, as open to inspection under Sect. 91, comprises also the addition to the mixture of ore and acid of any material which produces additional solid particles in the mass.  This subject-matter does not appear in the Specification as accepted.

Title: An electrical induction transfer device
IPC: G06G7/22
Filed: 1959-01-23
Abstract: 881,056. Transformers; selsyn machines. HERR, D. L. Jan. 23, 1959, No. 2578/59. Classes 35 and 38 (2). A device for producing voltages or torques varying with the angle of rotation of rotor shaft 13 (Fig. 1) in accordance with a predetermined function of the angle comprises a stator 11 surrounding the coaxial rotor 12, both being wound toroidally, the number of winding turns in each stator slot corresponding to the increment or decrement required by the predetermined function for the angular increment corresponding to the spacing of that slot from the preceding slot, the total flux in the rotor and the stator being zero. The stator is made of thin laminations, provided with winding slots 37 (Fig. 2) which accommodate one side of the stator coils and has radially projecting teeth 38 on its outer periphery forming channels which accommodate the other sides of the stator coils. Formulae are given for calculating the various stator and rotor dimensions marked in Figs. 2 and 3, in terms of the numbers of stator and rotor slots and of ro- (Figs. 4 and 5, not shown). Three dimensioned examples are given. The bars between the stator slots and the rotor slots are of constant width and the flux in the rotor and stator, though unsaturated, is close to saturation level. The windings are put on by modified toroidal coil winding machines so that accurate and consistent positioning and tensioning is secured. The stator end laminations 69 (Fig. 7) are made of insulating material and have grooves 70 to accommodate the cross-over conductors. The stator windings 110, 112, &c. (Fig. 9), vary according to the increase or decrease in flux which they are required to produce in the stator periphery in order to produce at related positions in the air gap between the rotor and the stator the correspondingly varying flux needed for generation of the function. Fig. 8 shows an arbitrary function the successive ordinates being disposed at distances along the abscissa representing the distance between the slots. Position 2 corresponds to the third slot 104 the number of turns in which corresponds to the increment 100. The number of turns in 106 corresponds to the increment 102 at position 3 and the absence of turns in 108 corresponds to the absence of any increment at position 4. The total flux in the device is such that the areas under the curve above and below line 134 are equal and there is no leakage flux.

Title: Improved automatic control system for electric motors
IPC: H02P7/06
Filed: 1927-02-03
Abstract: 284,860. James, H. V. Feb. 3,1927. Speed-maintaining systems.-In an automatic control system for electric motors which employs a pilot motor and " speed up " switches, a centrifugal governor driven by the main motor operates switches in the control system so as to prevent the main motor from exceeding a predetermined maximum speed regardless of its load. The invention is shown applied to the control system described in Specification 109,890 wherein speed-up buttons d and slow-down buttons e rotate in opposite directions a pilot motor P with two oppositely-wound armatures, to operate the control apparatus of the main motor. The main motor drives a centrifugal governor G which, by means of an arm L, at the predetermined speed opens at a (in series with buttons d) the speed-up circuit of the pilot motor, and closes at b (in parallel with the buttons e) the slow-down circuit.

Classes 97(1) and 97(2) Tq assist in the measurement of the intercept of a measuring staff used in a surveyor's level the latter has arranged in front of it optical elements having a wedge effect and adapted to deflect the line of sight of the level by any suitable angle in the vertical direction. Fig. 1 shows the invention applied to a level having a pendulously suspended reflecting prism 42 arranged to maintain the line of sight horizontal when the instrument is tilted. Before the objective 31 are two prisms mounted in bearings 11 and 12 and simultaneously rotatable through equal angles in opposite directions by a gear 13 operated by a knob 15, such rotations changing the line of sight in the vertical plane. The member 2 carrying the prisms is rotatable through 180 degrees about the optical axis on a member 3 supported by the casing 30 of the level so that the line of sight can be changed from a certain angle upwards to the same angle downwards. The field of view of the eyepiece 32 is shown in Fig. 4, 22, 23, 24 and 25 being stadia lines on the graticule 35 (Fig. 1) of the instrument and 22<SP>1</SP>, 23<SP>1</SP> the images of marks on a distant measuring staff framed by the level. Rotation of the prisms 8 enables. the images 22<SP>1</SP>, 23<SP>1</SP> to be moved relative to the stadia lines until one of the latter coincides with a wholenumber mark on the image then the intercept of the image by the stadia lines may be read more easily.
