Title: Conveyor systems
IPC: B65G43/00
Filed: 1977-03-03
Abstract: 1535006 Rail vehicles-overload check SIEMENS AG 3 March 1977 [15 March 1976] 8919/77 Heading B7H Railcars are checked for overload by measuring the traction current of each car in a measuring section of the railway network. Each car F is supplied from current rails 81-S3 via brushes B1-B3 and in the measuring section S20 the current is monitored by resistor Rm coupled to a Schmitt trigger circuit SS which is tripped to provide a warning signal A when the voltage across the resistor exceeds a set value. The value can be set in dependence on the maximum gradient in the network or on the maximum gradient to be met by the car on its specified route. The warning signal can actuate a set of points to route the car off the main track.

Title: Exhaust silencer for internal combustion engines
IPC: F01N1/12
Filed: 1928-03-24
Abstract: 314,322. Quarmby, A. H. March 24, 1928. Exhaust silencers.-The gases enter by a tube 1 which is provided within a casing 3 with elongated tangential outlet slots 4 communicating with relatively narrow, spiral, or otherwise curved passages 5 which discharge tangentially into relatively large outer tubular members 6. These tubes have extensions 12 which discharge through radial slots 14 into a chamber 16 whence they pass to the atmosphere through an outlet pipe 16. The tube 1 has a closed end 7 adjacent a dividing plate 11 held between the flanges 8, 9. The extensions 12 pass through holes in plate 11 and are provided with collars 15 to prevent leakage. Cooling air is admitted through apertures 17 in the end wall 2 of casing 3 and escapes through circumferential apertures. The manner of withdrawing gases from tube 1 creates a vortex with a central zone of low pressure, and turbulence is created in the outer members 6, and these movements tend to reduce back pressure and prevent deposition of carbon particles. In view of the freedom from baffles, the silencer readily lends itself to cleaning.

Title: Improvements in and relating to twisting and winding apparatus
IPC: D01H7/78
Filed: 1926-04-06
Abstract: 260,488. Hubbard, C. W. April 6, 1926. Winding-machines; twist tubes and like twisters; spindle apparatus.-Relates to twisting and winding apparatus of the kind wherein the yarn is led through a hollow spindle to a rotary yarn-container wherein it is laid in layers transverse to the axis of rotation by means of a winding-head. The winding-head, which comprises a slotted presser plate 9, a yarn-laying arm 11, means to traverse the arm longitudinally of the slot in the plate, and means to rotate the plate and yarn-container 1 relatively to each other, is fast on the spindle and carries the container, in which the yarn mass 4 is built between the plate and a plug 3 adapted to slide downwardly, by means of a housing, so that the thrust thereon is borne by the spindle bearings. The presser plate is connected by studs 12 to a plate 13 fast on the lower end of the spindle 6, and the container is secured by means of spring-controlled pins 18 to a housing 17 freely mounted on the winding-head. A plate 14 is fast upon the spindle and carries planet wheels 26, which are geared with an independently driven pinion 22 and are connected with a gear 29 on the hub of the housing and with a gear 36 fast on a sleeve 35 which carries a cam 31. The speed of the yarn-container is varied relatively to that of the spindle and the winding-head by varying the speed of a wheel 30 geared to the pinion 22. The cam 31 operates the arm 11 by means of a vertical rocking shaft 32 and arm 33, and similarly operates a compensating-arm 37 which engages the yarn and maintains it at a uniform tension. Capstan wheels 42, 43 which draw the yarn from the supply are mounted on a head 46 fast on the spindle and are geared with a driven pinion 48. The step bearing 2, Fig. 4, of the container is rotatably mounted in the upper end of a plunger 52, which is raised in a cylinder 53 to move the yarn container into operative engagement with the housing by means of compressed air, and is maintained in its elevated position during the winding of the yarn by means of a pin 56 which may be withdrawn by means of a treadle or arm 60. In a group of devices the locking- pins may all be withdrawn simultaneously by operating the shaft 62 upon which the treadles 60 are mounted, pins 63 operated by the treadles engaging slots 65 in the shaft to allow of individual operation by means of the treadles if desired.

Title: Process for applying a protective coating to metallic articles
IPC: B05D3/02
Filed: 1931-03-24
Abstract: Protective coatings are applied to metallic articles by dissolving or suspending an induratable artificial resin in tar oil together with inorganic fillers, such as heavy spar or quartzite, the solution or suspension being applied to the hot article by dipping, brushing or spraying.  The boiling point range of the tar oil is so selected as to coincide with that at which the resin passes into the insoluble and infusible condition. Other organic materials of high boiling point, such as anthracene oil boiling above 300 DEG  C., may be added and the resin may be used in the powdered, liquid or semi-liquid condition.  In an example, a metal tube, heated to 260-280 DEG  C. during the operation, is brushed or sprayed with a suspension of a finely powdered cresolformaldehyde resin in tar oil boiling between 210-240 DEG  C., an equal amount of finely powdered quartzite being included.

Title: Steam and water separator for a sea water evaporator
IPC: B01D1/30
Filed: 1954-03-29
Abstract: <PICT:0753748/III/1> <PICT:0753748/III/2> A separating chamber 18 for removing water droplets from the steam generated in a sea water evaporator comprises a dome 12 having a cylindrical side wall and provided at the base with a conical partition 23 through which the steam inlet conduit 21 protrudes, wherein a plate 33 depends from the top of the dome dividing the upper part of the chamber into two segments and has, at its lower edge, an inclined gutter 34, and the dry steam outlet conduit 30 passes through the side wall of the chamber at the opposite side of the plate to the gutter.  The plate and gutter prevent the water which separates on the walls of the chamber from "creeping" along the walls towards conduit 30.  Water which separates on the plate itself drains into gutter 34; and then overflows and runs down the side wall of the dome.  In the embodiment shown, the separating chamber 18 is mounted on a primary separating chamber 16, and the latter is disposed above the boiler chamber (not shown).  An external conduit 19 introduces wet steam from the boiler tangentially into the upper part of chamber 16.  The steam whirls round the chamber 16, and much of the water entrained therein is thrown by centrifugal force against the shell 10.  The water runs down the wall and over ring 20, and is then collected for return to the boiler.  The relatively dry steam passes through the side opening 22 in conduit 21, and rises through the latter into chamber 18.  The bottom end of conduit 21 is closed, and apron 24 is secured thereto. The apron covers the opening in ring 20, and prevents water splashing into the primary separating chamber.  The apron also provides a surface for draining away water collected on conduit 21.  The steam entering chamber 18 through conduit 21 has a whirling motion instituted in chamber 16.  The longer end 35 of plate 33 is disposed to face the whirling stream of steam in the chamber. In whirling within chamber 18, substantially all of the remaining water is separated from the steam.  The water runs down plate 33 and the side wall of the chamber; it then flows through perforate plate 25 into sump S on conical partition 23.  Plate 25 prevents water from splashing from the sump into chamber 18.  The water is drained from the sump by pipes 26, coupling 27, and pipe 28 which leads to the sea water supply vessel.  The dry steam outlet conduit 30 is provided with a flared open end 31 which projects well into the dome in order to prevent water creepage along conduit 30.  Specification 674,385 is referred to.
