Title: An improved regulator valve for locomotives
IPC: F01B25/00
Filed: 1927-11-18
Abstract: 305,732. Fairless, T. Nov. 18, 1927. Railway locomotives, steam. - The regulator valve is enclosed in a housing having a readily detachable inspection cover, is interposed between the dry steam pipe and the cylinders, and is adapted to be isolated from the boiler by means of a valve fitted in the steam supply pipe, so that the regulator valve can be removed or inspected while the boiler is under steam. When the invention is applied to an existing locomotive the usual regulator valve may be employed as the isolating valve. In the construction shown in Fig. 1 steam is supplied from the boiler through an isolating valve (not shown) and an external pipe 6 to the inlet passage 5 of a superheater header 4. Dry steam passes from the heater units 7 to lateral passages 8 which communicate at their upper ends with a steam space 9 above the regulator valve 10 having a conical seat 11. When the valve is lifted bv means of a crank arm 20 and a rod 13 the dry steam passes through a passage 3 to the steam pipes 1 leading to the cylinders. A small amount of clearance 14 is provided between the valve 10 and the rod 13 to ensure that the valve will seat correctly. The lower seating of the valve is slightly larger than the upper or piston portion so that the steam pressure in the space 9 tends to keep the valve closed. The valve skirt 10<b> is cut away to provide V-shaped notches to give a gradual opening as the valve is lifted. A detachable cover 15 forms a guide for the piston portion of the valve. The valve and superheater casting are arranged in a dome 17 just behind the smoke-stack 18. In a modification the steam supply pipe 6 is inside the boiler.

Title: Apparatus for depositing bobbins on pin-boards
IPC: B65H67/06
Filed: 1960-09-09
Abstract: 938,276. Collecting bobbins from winding machines. K. J. SCHARER, [trading as MASCHINENFABRIK SCHARER]. Sept. 9, 1960 [Sept. 11, 1959], No. 31125/60. Class 120 (3). In apparatus for automatically loading a pin-board, wound (or empty) bobbins delivered from a winding machine by a shoot or inclined slide are successively received and supported by a bottom piece carried by a traversing ledge moving transversely to the slide. A control cylinder movable in response to the deposition of each bobbin on the board comprises cams (arranged in correspondence with the arrangement of pins) which coact with a feeler to cause removal of the piece to an ineffective position to enable transfer of the bobbin to an empty pin. The piece is restored to its supporting position as the apparatus is prepared to receive the next bobbin. As shown in Fig. 2, after bobbin A has been delivered to a pin 3, an additional bobbin B falls from the slide 28 on to a catch rail 17 secured to a traversing ledge 11 but is also held temporarily by the end of the slide. When the bobbin registers with a recess 16 it falls into the position shown in Fig. 3, where it is supported by a bottom piece 15 and steadied by a forked holder 18. The weight of the bobbin tilts a lever 7, 8, so that a feeler roll 6 is engaged by a cam 5 on a control cylinder 4 to pivot a lever 9 (against the bias of a spring 13) from engagement with an abutment 14 and move a tongue 9a towards a magnet 12 which then rapidly completes the movement of lever 9, Fig. 4, so that piece 15 releases the bobbin and allows it to fall on to a pin 3. Continued movement of ledge 11, Fig. 1, causes a bolt 19 to engage a lever arm 20 which, through arm 22, link 23, arm 24, ratchet and wheel 26, 27, rotates cylinder 4 an increment to position another cam 5 corresponding to the next empty pin 3. At the end of the ledge traverse, bolt 19 engages and is downwardly urged by a stop member 21 so that lever 9 swings towards ledge 11 and the tongue 9a is disengaged from magnet 12 so that spring 13 restores lever 9 and associated mechanism to the position shown in Fig. 2. In a modification, 12 is an abutment, 14 is a magnet and the bias of spring 13 is reversed.

The steel plate 2 is slightly tilted, so that unvaporised water runs off through a pipe 7, which may however be used for supplying water to the plate. The heater may be arranged surrounded by heat insulation material in a casing 1, above which may be a sterilising chamber.

A tool for flaring the end of a metal pipe 40 comprises a pair of relatively movable jaws 11, 12, a die piece 30, and means 20 for moving the die piece and the jaws relatively towards each other in an axial direction, and is characterized by the die piece 30 being provided with a spigot 35 formed as a member separate from the die piece, a portion 34 of the member forming the spigot being detachably secured within a recess 33 in the body of the die piece. To deform the end of the pipe 40 to form a flare, the pipe is inserted between the jaws 11, 12 and clamped so that its inner end projects from the upper end of the jaws. The die piece 30 is then inserted between a thrust member 21 and the pipe, with the spigot 35 in registry in the inner end of the pipe. A spindle 20 is rotated to move the thrust member 21 into abutment with the die piece 30 after which the die is forced downwardly thus deforming the end of the pipe with the complementary conical surfaces of the body part 31 of the die piece and the upper end of the jaws.

AIII Bv type refers to a compound of one of the elements B, A1, Ga, or In with one of the elements N, P, As or Sb. The field may be measured by means of a bridge circuit adapted to measure the change in resistance of the member when subjected to the magnetic field. Alternatively the Hall effect of the member may be utilized as shown in Fig. 2, in which measurement is effected by balancing the Hall potential developed in member M against a standard potential obtained from potentiometer K.

Abstract: 1448201 Automatic gear checking ILLINOIS TOOL WORKS Inc 14 Sept 1973 [14 Sept 1973] 31527/72 Heading G3N A gear tooth checking system (checking helical lead and involute) comprises means encoding the angular motion of a gear supporting table 12 providing pulses which are passed through a pulse multiplier of pre-set adjustable factor and serve to synchronize the linear motion of an involute probe 16, or lead probe 20, see also Fig. 1 (not shown), with the rotary motion of table 12, the linear motion corresponding to an errorless gear profile. The encoder 28 is coupled to a small diameter drive wheel 30, spring, weight, or pressure bar biased against the outer periphery of a circular base disc 26 mechanically coupled to table 12. Switch 36 is set either for lead, or involute, and encoder pulses are further multiplied by eight in unit 60 for the lead mode only. The pre-set factor is set in index switches 66 and fed to BCD counter 70 counted to zero by pulse generator 68 simultaneously counting unit 64 up, until, when 70 and its digital read-out indicate zero, 64 contains the desired factor, fed to multiplier 62. One or other of drive channels 76-22-20, or 78-18-16 are active in dependence on the chosen mode (for control of contacts 44s, 54s see Fig. 3 (not shown)). For either mode pulse generator 38 provides driving pulses for drive 40-42 of table 12, and, in the involute mode provides pulses, via multiplier 86 to the drive 84-82 of a recorder 80 providing a written record of the gear checked. In the lead mode, the recorder is driven by the output of multiplier 62 via a further multiplier 88. The probes 16, 20 are such that pressure applied to sensing ends (16a, 20a)(Fig. 1) controls the movement of a magnetic slug in a differential transformer (not shown) to provide an electrical signal representing the contact pressure. Drive (18) moves probe (16) horizontally, probe (20) being moved vertically. The diameter ratio of disc 26 to wheel 30 may be adjusted as necessary.
