Title: Method and means for stabilising rail vehicles
IPC: B61C15/00
Filed: 1936-02-11
Abstract: 462,926. Locomotives. ROCARD, Y. A. Feb. 11, 1936, No. 4172. Convention date, Feb. 11, 1935. [Class 79 (i)] [Also in Group XXXII] The oscillatory movement of a railway vehicle comprising a frame or frames with a number of axles is damped by arranging the wheels in front of the mass centre with a smaller radius and/or a greater bevel than those disposed behind the mass centre. The locations of the axles and the bevel of the wheels are determined in a manner such that the summation extended to all the axles of a frame or frames, of the quotient of the product of each axle to the mass centre of the frame, by the bevel of the wheels of this axle divided by the radius of the wheels is positive ; the distance of the axles from the mass centre being taken as positive on one side and negative on the other. As shown, the front axle 7 of the bogie 6 is disposed lower and carries smaller wheels than the axle 8, the bevel of the wheels on the axle 7 being greater than that on the axle 8, the pivot point 91 being displaced toward the front axle. The wheels on the front axles 1, 2 of the engine frame have a large bevel and the wheels on the axles 3, 4 little or no bevel. The wheels on the axle 11 of the bissel truck may have a slight bevel and the wheels on the axles 16-19 of the tender 12 have no bevel.

Abstract: 1484537 Surface flaw detection CIBA-GEIGY AG 30 Jan 1975 [1 Feb 1974] 4195/75 Heading G1A Apparatus for this comprises laser 1, optical system 3', 3" forming a flat beam whose plane is perpendicular to surface 5 on which the beams parallel rays impinge at a predetermined angle α, a movable diaphragm 7, transmitting lightsuccessively to individual surface regions on a line transverse to the direction of motion of material 5, an optical system 3''' and a device responsive to light collected thereby giving indications of the nature of or flaws in the individual regions. Visible or shortwave infrared light may be used. 3 and 3'' are cylindrical lenses. Photographic film 5 is advanced on rollers 6. Diaphragm disc 7, Fig. 2 (not shown), has eight arcuate slots 7b of different radii concentric with and subtending the equal angles at axis 7a, which is parallel to the light rays. As disc 7 rotates the regions on the material are successively illuminated through successive slots 7b, of which there may be more or less than eight. Specularly reflected light is stopped by opaque body 10, but light reflected from a flaw reaches photo-transistor 11 giving a signal through amplifier 12 to control lamps 13a corresponding in number to the slots 7b. Equally spaced holes 7c, with lamp 14 and photocell 15, control system 13b via amplifier 16, so that positional and defect signals are correlated in device 13. Preferably each signal from a lamp 13a lasts for one period of the diaphragm motion. In Fig. 3 (not shown) instead of disc 7 is an opaque strip (17) with a transparent slot (17a) perpendicular to the plane of the beam and displaceable parallel to it but perpendicular to the rays by an eccentric (17b).

Title: Automatic change-speed gear for vehicles
IPC: F16H61/02
Filed: 1963-02-04
Abstract: 985,011. Change speed gear control. FICHTEL & SACHS A.G. Feb. 4, 1963 [Feb. 2, 1962], No. 4488/63. Heading F2D. A change speed gear comprises an hydraulic torque converter and a toothed wheel gearing having ratio change by a centrifugal clutch, the engaging speed of which may be varied manually. A vehicle engine shaft 1 is connected to the impeller 2 of a torque converter having a turbine 3 connected to a sun gear 7 and to the driving side 15 of a centrifugal clutch 13. The planet carrier 9 of the threeelement epicyclic gear, 7, 8, 10, is connected through a one-way clutch 11 to the vehicle drive shaft 12 which is also connected to the driven member 16 of the centrifugal clutch 13. The restraining springs 19 for the clutch weight 18 are mounted on levers 20 such that movement of a lever 24, which may be the throttle control, determines the engaging speed of the clutch to change from reduced to direct drive in the epicyclic gear. In modifications the link 23 from the lever 24 may be vacuum-servo assisted, and the centrifugal clutch may bridge the torque converter.

Title: Improvements in or relating to fixing devices
Inventor: MOLYNEUX GEORGE
IPC: E04B1/41
Filed: 1969-12-18
Abstract: 1284595 Plastics socket for fasteners G MOLYNEUX 2 Dec 1970 [18 Dec 1969 30 Jan 1970] 61619/69 and 4502/70 Heading F2H A socket fixing device 10 for building into mortar, concrete, or other solidifying structural material to receive nails, screws or like attachment devices comprises a resilient plastics device to grip an attachment device driven into it, the device being shaped and tapered such that it is keyed into the material, which thus resists withdrawal of the device, and having guide means extending from the narrow end for constraining attachment devices driven into it to diverge from a predetermined longitudinal line. The device, as shown in Figs. 3 and 4, is preferably formed from an integral plate-like moulding having two complementary elements 16, 18 joined by a thin transverse strip (14) about which the elements may be hinged together, as in Fig. 3, and fastened by means of peg 42 and coacting hole 44. Each element 16, 18 has a series of grooves 30 formed therein so that when the device is folded, complementary grooves define longitudinal holes for receiving attachment devices, each groove having a portion normal to the narrow end and a longer diverging portion partially blocked by thin, lateral webs 34, 36. External lateral grooves 50 and saw-tooth edges 26 assist in keying the device 10 into a wall, as does a core of solidifying material entering the central hole 45. Location lips 27, 28 with chamfers 40 may be formed at the narrow end of the device. As shown in Fig. 4 the device 10 is built into the mortar 52 between bricks 54, 56 with lips 27, 28 standing proud to serve as a guide for plastering, some plaster entering and becoming keyed in holes (29) in the lips. A nail 59 can then be driven into the device 10 and be gripped by the webs 34, 36 and by the resilience of the plastics material. The divergent path of the nail in groove 30 will further serve to resist extraction of the nail. In an alternative embodiment, as in Fig. 5 (not shown), the device is formed in two physically separate plate-like elements with no lips or central hole, but with grooves (62) of different sizes to receive nails or screws of different diameters.

Title: Automatic brake slack adjuster
IPC: F16D65/60
Filed: 1975-02-04
Abstract: 1491906 Slack adjusters for brake transmitting mechanisms AEROQUIP AG 4 Feb 1975 [19 Feb 1974] 4646/75 Heading F2E The broadest aspects of construction and operation of the invention claimed are extremely detailed and are indicated by the description which follows. Brake application is effected by movement to the right of a brake-actuating rod 21 connected to an arm integral with a body member 11, Fig. 1, of an adjuster 10. A brake-operating shaft (e.g. a camshaft), (not shown), is thereby rotated by means, e.g. of a first worm-gear 22 and a first worm 23 mounted on a connecting shaft 27 which in this phase is not rotated. During this phase a drive shaft 35 is also rotated clockwise, by means, e.g. of a link 41 linking rod 21 with a crank arm 40 secured to the drive shaft; the drive shaft 35 in turn rotates a first bearing member, 43, Fig. 3, by means, e.g. of a crank pin 52 extending from an enlarged end 53 of the shaft 35 into a slot 54, Fig. 4, clockwise without lost motion at this stage. A helical spring 46 forming part of a first clutch 36 is inoperative because the rotation of bearing member 43 (forming the other part), which partly surrounds it, reduces its outside diameter, so member 43 slips around it, and a component in the form of a second worm 26 surrounding the remainder of spring 46 is not rotated in consequence. Second worm 26 is kept stationary in this phase by connection with a fixed second bearing member 47 through a helical spring 50 (of opposite hand to spring 46), parts 47, 50, constituting a second clutch 37. On brake release, the brake-operating shaft and the drive shaft 35 are rotated counterclockwise, so bearing member 43 is also rotated counter-clockwise, Fig. 4. If the lost motion at 52, 54, is more than taken up, the first clutch spring 46 now entrains the second worm 26 which is simultaneously released from the second bearing member 47 by disengagement through the second clutch spring 50. Connecting shaft 27 is therefore rotated by, as shown, a second worm gear 25 meshing with worm 26, so the angle through which the brake-operating shaft is rotated is changed by the driving connection 23, 22, in the sense to reduce the brake clearance. Preferably the second worm gear 25 is spring- loaded at 31 and a cover plate 32 is provided so that, on removal of the cover plate, gear 25 is forced out of engagement with worm 26 to permit manual rotation of shaft 27 by a hexagonal part 30 for adjustment.

Title: Apparatus for removal of electric charges from the surfaces of webs of dielectric materials
Inventor: AMOS STEPHEN EARL
IPC: D01G23/00
Filed: 1965-02-03
Abstract: An apparatus for the removal of charges of static electricity from the surfaces of a travelling continuous web of dielectric material, e.g. threads of synthetic fibres, comprises a closed tubular member disposed transversely of and adjacent to the travelling web and having an electrically conductive wall pervious to gas in the area thereof immediately adjacent to the travelling web, means for continuously feeding gas under pressure to the interior of the tubular member whereby gas is continuously forced through the pervious area to maintain a blanket of gas of predetermined thickness between the surface of the tubular member and the web travelling thereover, and a low resistance electrical conductor connecting the electrically conductive wall to earth. The electrically conductive wall may be a wall of sintered metal, e.g. sintered bronze or a porous carbon.  The tubular member may be cylindrical.  In the use of air spreaders employing air emission from the gas pervious passageways in the wall of sintered metal tubular film web guides to remove longitudinal wrinkles from the travelling web, it is found that direct earthing of the guide with a very low resistance conductor (such as a heavy copper wire) in accordance with the invention causes static charges to be completely removed from the web but that the usual earthing of the guide achieved by mounting the guide on the steel framework of the machine is not adequate to effectively neutralize the charge on the web.

Abstract: 384,137. Variable-speed gearing; clutches. ALVIS CAR & ENGINEERING CO., Ltd. and CLARKE, G. T. SMITH-, Alvis Works, Holyhead Road, Coventry. Feb. 18, 1932, No. 4763. [Class 80 (ii).] In an epicyclic variable gear for motor cars comprising a slipping centrifugal clutch, the sun gear 2, Fig. 1, is fast on the driving shaft 3, the carrier 4 of the planets 6 is fast on the driven shaft 5, and the annulus 7, which is secured to a clutch drum 9, is journalled at 12 and 10 on the driving and driven shafts respectively. A flywheel 8 on the driving shaft carries shoes 14, Fig. 2, pivoted at 15 and held inwards by springs 16, the pivot 15 of one shoe acting as a stop for an adjacent shoe and as a holder for the spring of the diametrically opposite shoe. Each shoe is recessed to receive the spring of an adjacent shoe. The springs may be mounted on eccentric cam portions 17 on the pivots 15, so that the tension of the springs may be varied by turning the pivots. As the driving shaft is accelerated, the shoes 14 move outwards into contact with the drum 9 thus bringing the annulus gradually to rest and then accelerating it in the same sense as the driving shaft and increasing the gear ratio until a solid drive is obtained. By turning the pivots 15, the gear change may be caused to come into operation at a different speed of the driving shaft, or the drive may be disconnected altogether as in an ordinary clutch. A brake band may be applied to the drum 9 to keep the annulus 7 stationary for a definite speed.
