Patent ES-339618-A1 (ES)
Title: Improvements relating to Pneumatic Fibre Feeding Arrangements for Textile Cards
IPC: D01G23/02
Filed: 1967-04-21
Abstract: In a pneumatic feeding arrangement for conveying fibrous material to a plurality of carding machines C1-C6, each carding machine has a tapering, closed topped, chute 11 with means 20, 21 at the bottom of the chute for delivering the fibrous material in sheet form to the card, a trapezium shaped opening in one side wall of the chute being releasably connected to a supply duct 29 and a smaller trapezium shaped opening in the opposite side wall being releasably connected to an outlet duct 30. Fibrous material fed in an airstream through duct 29 has its flow cross section abruptly increased as the flow enters the upper part of chute 11 provided that the level of fibres in the chute is below the bottom of the inlet opening, the resulting reduction in fibre flow velocity being sufficient to allow fibres to be deposited in the chute. Fibres collecting in chute 11 are compacted by the action of an oscillating wall 15 which swings about pivot 16. Sealing strips 49, 50 at the lower ends of the chute walls prevent air loss. A lever arrangement 41-47 allows for the adjustment of the spacing between the wall 12 of the chute and the nip between the roller 20 and the feed plate 21. Angled strips 33, 34, 35 surround the openings and ducts 29 and 30 are secured to the chute 11 by sliding flanges on the ends of the ducts behind the strips. An insert plate may be interposed between the end of a duct and the side walls to reduce the size of the opening and thus alter the flow rate. A wall of the chute may be transparent.

Title: Air brake cylinder with slack adjuster
IPC: B61H15/00
Filed: 1967-06-22
Abstract: An air brake cylinder for a railway vehicle disc brakes, is provided with automatic slack adjustment and is resiliently and pivotally supported on brackets extending from the vehicle frame. Automatic slack adjustment.-This is provided in the coupling between a non-rotatable tubular piston-rod 4 and a non-rotatable push rod 11 connected to the brake rigging and disposed with the rod 4. The coupling comprises an abutment ring 13 fixed on the inner surface of rod 4, and nuts 14, 15 screwed on to the push rod 11 on each side of the ring 13. The lead of the screw threads makes the nuts non-self-locking. A spring 16 and a thrust bearing 28 are axially clamped between nut 14 and an abutment at the open end of the piston-rod 4 urging the nut against the ring 13. The nut 15 is urged against the ring 13 by a spring 20 disposed between the piston head 3 and a non-rotatable axially movable control ring 23 abutting the nut. The spring 20 prevents axial play of the rod 11 within the nut 15 and absorbs vibration transmitted from the vehicle to the push rod 11. A spring 21 axially clamped between the nut 15 and control ring 23 together with spring 20 holds the nut 15 frictionally engaged with ring 23 preventing rotation of the nut during braking. The piston 3 and rod 4 move to the left (as shown) to apply the brakes, push rod 11 being moved by abutment ring 13 and nut 14, the ring 13 being moved along by spring 21. When the braking stroke of push rod 11 exceeds a normal braking stroke the forward movement of the control ring 23 is stopped by an abutment in sleeve 19. As the push rod continues to move, spring 21 will oppose further movement of the nut 15 together with the push rod, and will yield sufficiently to permit nut 15 to lose its locking engagement with the ring 23. Thus nut 15 will be rotated by the spring 21 and displaced axially to the right (of drawing). When the braking movement of rod 11 ceases the nut 15 is again locked against rotation. During return of piston 3 to its brake release position (as shown), the rod 11 will move with respect to the pistonrod 4, to take up slack. Mounting.-A substantially horizontally orientated bolt 31 passes through metal plates 32, 33 extending from the vehicle frame, and through a bore in a bracket 35 extending from the brake cylinder. Within the bore are metal rings 36, 34 between which are rubber rings 29 separated axially by a metal bush 30. Reference has been directed by the Comptroller to Specification 1,144,685.

Filed: 1968-10-17
Abstract: In a submersible pump assembly for pumping fluid cargo from the tank 13 of a ship, comprising a pump impeller 32 driven by an hydraulic motor 33. the fluid to be pumped, e.g. oil, solvent, heated molasses or liquefied gases, is separated from the motor driving fluid, e.g. oil, by a zone which is maintained at a relatively low pressure so that any leakage of the fluids collects in the zone from where it is intermittently removed as by a remotely-controlled ejector 72. The zone includes a drainage chamber 55 surrounding the shaft 14 between two sets of shaft seals 51, 52 and 53, 54, and a chamber 68 surrounding a chamber 64 containing the motor 33. The motor receives driving oil through a conduit 37 and discharges the spent oil through the chamber 64 and a conduit 38. The chambers 55, 68 are communicated via a pipe 69 and are kept at the relatively low pressure by communicating them with atmospheric pressure via a long pipe 24 which extends upwardly to a hatch cover at the top of the tank 13.

Title: Flame scanner with head means incorporating mechanical shutter checking device
IPC: F23N5/08
Filed: 1968-12-26
Abstract: A flame detector comprises a sensing element mounted in a tube with a shutter biased toward an open position and actuable electro-magnetically into a closed position where it shields the sensing element from the flame. Failure of a flame irradiating a discharge tube detector 16 is simulated by closing shutters 78, 80 formed of a non-magnetic stainless metallic material having a spring constant unaffected by high temperature. Closure of the biased-open shutters is effected by D.C. energization of coils 38 of horseshoe magnets 30, 32 which co-operate with magnetic members 28 on the shutters. Quick opening of the shutters is ensured by application of a small A. C. energization when the D.C. is removed. The electrodes of the tube 16 are parallel to the slot formed by shutters 78, 80 as they open.

Patent ES-420614-A1 (ES)
Title: Inspecting glass
IPC: G01N21/88
Filed: 1973-11-16
Abstract: Inspection of flat glass or other transparent or reflecting material for vision distortion or optical quality by observing the lens power and width of positive and negative lenses on the surface or surfaces of the material. Two accurately spaced beams of light are directed toward the glass or other material being inspected, and the beams are then directed from the material to a chopper device. A photocell in the chopper device produces an electrical signal of two pulses separated in time by an amount proportional to the spacing between the beams as they arrive at the chopper. The spacing of the beams at the chopper changes in proportion to the reciprocal of the focal length of the lenses on the surface or surfaces of the sample, with a positive or convex lens causing the beams to converge and a negative or concave lens causing them to diverge upon leaving the sample. This causes a corresponding change in the time separation of the pulses from the photocell. The pulses are suitably electronically processed and the resulting signal is graphically recorded on a strip chart as an indication of position and focal length of lenses on the surface or surfaces of the material. Changes in the index of refraction within transparent material may also be detected.

Title: Lubrication for heavy duty thrust bearings
IPC: F16C33/10
Filed: 1974-02-21
Abstract: This invention relates to an improved self-lubricating sleeve and thrust bearing configuration, wherein lubrication of the thrust bearing surface may be augmented by an additional supply of oil. The sleeve bearing includes a circumferential oil receiving slot disposed in the upper half thereof and a plurality of axial oil feeding grooves which extend generally downward in a radial direction and in communication between the circumferential oil receiving slot and the thrust bearing surface.

IPC: F23C9/00
Filed: 1974-12-24
Abstract: A flame is produced in a combustion chamber with a burner supplied with fuel and less than the amount of air for complete combustion. The remainder of the air required for complete combustion is injected separately. Stack gas containing substantial carbon dioxide is mixed selectively with the gaseous combustion products.
