Filed: 1927-02-14
Abstract: 268,736. Eckel, E. C. March 31, 1926, [Convention date]. Aluminous cement and ferro-silicon or highsilicon pig iron are simultaneously produced by fusing in a blast or electric furnace a mixture comprising lime, alumina, silica, and iron oxide in suitable proportions in the presence of sufficient carbon to reduce most of the iron and part of the silicon. The resulting cement should contain lime and alumina in the proportion of 5CaO, 3Al2O3' and should contain not more than 5 per cent of ferrous oxide and 15 per cent of silica. The ferro-silicon may contain 10-45 per cent of silicon. The invention renders possible the use as aluminous raw materials of siliceous bauxite or of high-alumina clays such as siliceous diaspore, kaolin, and halloysite.

Abstract: 540,292. Coupling rotating members. OSTBERG, K. G. March 9, 1940, Nos. 4464 and 4465. Convention dates, March 16, 1939, and Feb. 17, 1940. [Class 80 (ii)] [Also in Group XXII] In a chuck of the kind in which jaws or other gripping devices 6 are operated by rotating a screw or other member 11 relatively to the body 1 by means of a member 2 and a hand-operated setting sleeve 18 connected to the member 2 through reversing gearing, this gearing comprises a number of balls 20 or other rolling members engaging both sleeves and loosely mounted in recesses of a holder 21 stationary in relation to the body 1. The member 2 may take the form of a hand-operated sleeve, Fig. 1, which is rigid with a head 5 in which the jaws 6 slide and these engage radial slots of a disc 10 secured to the left-handed screw 11 which thus partakes in any rotation of the sleeve 2 relative to the body and operates the jaws. The balls 20 engage flanges 3, 19 of the sleeves 2, 18 and the opposite sides of these flanges are engaged by balls 4, 23 engaging respectively a flange of the body 1 and a ring 26 engaged by a spring 27 and nut 24 adjustable thereon. The screw 11 engages a nut 12 mounted in the body 1 so that it can rotate through an angle limited by projections 15. 16, Fig. 3, on the nut and body and balls 13 which also engage sloping races 14 and wedge when the screw is closing the jaws. This prevents jamming of the screw even if of small pitch. With a pitch of over 10 degrees and a square thread the screw 11 may engage the body directly. If the sleeve 18 is arrested while the chuck is rotating, the head 5, and screw 11 are rotated relatively to the nut 12, thus lifting the grippers 6 and releasing the tool. The reverse movement is effected by arresting the member 2.

Title: New or Improved Method of and Means for Converting Normal to Gun Range or vice versa.
Inventor: SHOVE RALPH SAMUEL
IPC: F41G11/00
Filed: 1917-03-28
Abstract: 127,052. Shove, R. S. March 28, 1917. Calculating - apparatus for determining the total correction to be applied to the normal range to correct for such variable factors as air and charge temperature, air pressure, and wind. The apparatus comprises movable scale and index parts, operated through suitable linkages by four or less grooved arms actuated by cam slots in a rotary range disk and so constrained that the two ends of each arm slide in parallel paths, the amount of movement of the scale and index being dependent on the angle of inclination of the arms with respect to their direction of movement. In the apparatus shown, the scale comprises an index slide 12<a>, Fig. 7, operated by a lever 18 which is controlled by the two grooved arms 27, 35 for air pressure and air temperature respectively, and a graduated slide 12 operated through suitable linkage by the grooved arm 44 for charge temperature. The arm 27 has a groove 24 engaging a stud 21 on the lever, a stud 30 engaging a groove 31 in a slide 32 which can be set up or down according to the air pressure, and a stud 29 which engages a 'cam groove B, Fig. 3, in the rotary disk and also engages a radial slot 9<B> in the front of the casing. At normal pressure the slide 32 is set so that the arm 27 is parallel to the slot 9<B> so that movement of the arm due to rotation of the disk causes no corresponding movement of the arm 18 and index slide 12<a>. The action of the other arms 35 and 44 is similar, the total effect being that the sum of the corrections is read on the scale 12 opposite the index 14. An indicator for resolving the force of the wind may be provided on the back of the apparatus, Fig. 2, comprising two rotary disks 67, 66. The top disk is transparent and has engraved on it a radial line 68 graduated in forces of wind, while the under disk is marked in squares on the same scale and graduated as shown, and with an index mark. When the lower disk is rotated to bring its pointer in the direction of the target and the upper disk is rotated to bring its graduated radius parallel to the wind, the strength of the wind can be resolved by means of the squares.

Filed: 1947-02-18
Abstract: 643,016. Linear-dimension gauges ; indicating-apparatus. MALAGRINO, F. Feb. 18, 1947, No. 4673. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 20, 1947.] [Classes 106 (ii) and 106 (iv)] A linear-dimension gauge for internal gauging comprises a casing formed by a cover 14 and a member 1 which is extended to form a fixed gauge leg 1<SP>1</SP>, and a leg 3<SP>1</SP> integral with a member 3 which is mounted on roller or ball-bearings 32, 32<SP>1</SP>, 33, 34 and adapted to slide transversely of the member 1 within the casing. The gauge legs 1<SP>1</SP>, 3<SP>1</SP> are normally urged apart by a coil-spring 5 arranged between the members 1, 3, the latter having a push knob 35 secured thereto, and a scale 15 thereon cooperating with a datum 17 on the fixed cover 14. The slidable member 3 carries a worm shaft 37 meshing with worm teeth 38 on a pin rotatable about a fixed axis. This pin carries a spur gear 39 meshing with a pinion 40 fixed on the shaft of a pointer 12 movable over a scale 13. One division of the scale 15 is 1 mm., and this is equal to one complete rotation of the pointer 12. To extend the range of gauging, auxiliary gauging elements 47, Figs. 1 and 7, provided with anvils 55, can be attached to the legs 11, 31. These elements have pivots 48 fitting into holes on the legs 1<SP>1</SP>, 3<SP>1</SP>, and curved slots 50 engaging over pins 51 on the legs. Each anvil 55 forms part of a member 52 which is slidable on the element 47, and adjustable thereon by means of an eccentrically-mounted roller 53. To take up backlash in the gears &c. and for correction purposes, the worm shaft 37 is extended and shaped at the end to fit a spanner. By rotating the worm shaft, the pointer 12 can be adjusted. Correction of the pointer 12 is also automatically applied during use of the gauge, by providing a friction-tight clamp 42 on the shaft 37, a pin 41 on the clamp engaging a specially-shaped slot 44 formed by a pair of plates 45 secured to the member 1. Thus when the member 3 slides over the member 1, the engagement of the pin 41 in the slot 44 causes partial rotation of the worm shaft 37. The clamp 42 allows the shaft 37 to be rotated independently by a spanner.

[Class 105] The different signal aspects are transmitted to a train, either by a resonance circuit on the track which is tuned to different frequencies by switching in condensers the combination of condensers being so allocated that a more restrictive signal is given if a condenser lead breaks or a contact fails to close, Fig. 1, or bv combinations of resonance circuits on the track the combinations for the different aspects being so selected that absence of an element in a combination or the addition of an element thereto gives a disturbance signal, Fig. 4. In the arrangement shown in Fig. 1, the clear signal is given when all three condensers 3, 4, 5, are in circuit ; the caution signal is given when the two condensers 3, 4 are in circuit; the danger signal is given when only the condenser 3 is in circuit. Series condensers may be successively shunted out to give the less restrictive signals, Fig. 2 (not shown). In the arrangement shown in Fig. 4, the four different aspects are given when the following combinations of the two different frequency circuits I, II at each side of the track are effective : I, I, II, II for .clear ; I, II for first caution ; II, II for second caution ; I, I for danger. Thus if one element is absent in a combination or an element is added thereto, a false aspect is not given. The improper combination gives a disturbance signal. A time delay device is provided so that the signal is only given after all the impulses have been received. The Specification as open to inspection under Sect. 91 comprises also arrangements in which the different aspects are transmitted by different numbers of impulses, a reduction in the number of impulses giving a more restrictive signal. As shown in Fig. 5 (Cancelled) for two-aspect signals the clear signal is transmitted if three impulses are given while the danger signal is given by a single impulse. This subject-matter does not appear in the Specification as accepted.
