IPC: B61B10/04
Filed: 1947-07-30
Abstract: 629,983. Rope railways. WEBB CO., J. B. July 30, 1947, No. 20599. Convention date, June 6, 1946. [Class 104 (ii)] [Also in Group XXXIV] A power driven system for moving independently supported loads along a conveyer line, e.g. for moving automobiles along the floor in a final assembly line, comprises a power-driven chain located between a pair of transversely spaced channel members 10 which have flat upper flanges 11 providing tracks for wheels 12 mounted upon the ends of an axle 14 which carries centrally disposed means 19 for. suspending the chain between the track members, and means for connecting the chain to the load. As shown, the chain-suspending means 19 comprises a bracket pivotally mounted on the axle and provided with two longitudinally extending legs 20 of an overall length approximately equal to the length of a side bar 21 of the power chain so that locking pins 22 which provide the pivotal connection between the links of the chain can be extended through holes in the legs 20 and held by nuts 23. The axle 14 serves also as a journal for a pusher dog 25 which has yoke members or arms 26 provided with holes for the passage of the axle, and is formed with a weighted tailpiece 29 arranged to bear upon the upper end 27 of the rearward locking pin 22. A load provided with an engaging member 31 may thus be pushed into engagement position by engaging the rear surface 30 of the driving dog 25 which is thereby tilted after which the weighted tailpiece returns the dog to driving position wherein its driving end 28 can engage behind the member 31. The axle 14 is made of tubular metal with both ends flared outwardly to wedge in position the inner rings of ball races, (see Group XXXIV), of which the outer rings are formed by the wheels 12. Annular plates on the inner sides of the wheels and disc plates on the outer sides serve to hold within the wheels a lubricant which is introduced through a nipple midway of the axle 14.

Title: An optical system for the simultaneous production of color separation images
Inventor: LEIGHTON THOMAS CARVER
IPC: G03B33/00
Filed: 1957-07-01
Abstract: 863,214. Forming colour separation images. COLORVISION Inc. July 1, 1957, No. 20684/57. Class 97(1) Optical systems for use in the simultaneous production of at least three colour separation images of an object comprises an objective, a field lens forming with the objective a real image of the object, a beam-splitting arrangement forming at least three differently coloured beams, and a relay lens in the path of each such beam. A prism may be provided so as to direct the beams from the relay lenses along parallel paths to form juxtaposed colour-separation images on e.g. a film. As shown, the system comprises an objective lens 17 which forms with a field lens consisting of components 29, 30 a real inverted image of the object in a plane A between the field lens components. Relatively inclined and axially spaced dichroic mirrors 31, 32 divide the light from this image into red, green and blue beams, the red and green beams being directed in a substantially vertical plane and the blue beam in a substantially horizontal plane. Each coloured beam is then folded by front surfaced mirrors (such as 52, 53 for the red beam) so as to be directed on to a prism block 47 after passing through a relay lens (such as 59). This block comprises reflecting faces 60, 75 for reflecting the red and green beams respectively, these faces being perpendicular to a vertical plane passing longitudinally through the optical axis and converging to a horizontal knife edge 83, Fig. 7. The triangular sides 84, 85 of the prism converge and terminate at opposite ends of the edge 83, and side 85 carries a wedge-shaped member 86 providing a reflecting surface 46 for the blue beams, the member 86 terminating at one end in a knife edge 87 disposed in the same plane as, but at right angles to, the knife edge 83. By means of this prism the coloured beams are directed in parallel relation and, preferably, through field flattening lenses to a single film on which three juxtaposed images are focused by the relay lenses so that they are accommodated in one film frame. Instead of a single film, the separate images may be formed on the faces of television cameras which may be arranged in a group with their axes parallel or, if prism 47 is omitted or a different prism is used, with their axes diverging. Specification 729,259 is referred to.

Title: Improvements relating to apparatus for handling waste material
Inventor: BROUGH JOHN STANIFORTH
IPC: B65F5/00
Filed: 1962-05-29
Abstract: 970,667. Comminuting sewage &c. MONO PUMPS Ltd., and HAIGH ENGINEERING CO. Ltd. May 17, 1963 [May 29, 1962], No. 20705/62. Heading B2A. Waste handling apparatus comprises a comminutor 10 having as its inlet a feed-tube 18 to depend into the waste material, so that for material to reach the comminutor, it must travel upwardly through at least part of the feed-tube, and a pump 14 connected to the outlet of the comminutor to draw a suspension of the waste material in a liquid through said feed tube and comminutor. As described, the feed tube extends into a tank 60 containing the waste in the form of a suspension in water, the pump and, in a further embodiment the comminutor, being controlled by a switch, which is actuated in response to predetermined upper and lower levels of waste material relative to the feed-tube by two electrodes 22, 24, or floats. The comminutor, which may be driven by the same motor as the pump, includes a fixed cutting ring having two sets of teeth for coarse and fine grinding, and a driven rotor comprising a slotted disc and two cutter arms carring four hardened-steel cutters. The pump shown is of the kind provided with universal joints at its driven end and comprising two helical elements meshing together enclosed one within the other, the outer element having one more thread than the inner element and being made of resilient material. It is arranged for the velocity of flow in the feed tube to be such that the heavy particles will drop out under gravity and so avoid the need for a screen to protect the comminutor. The drive to the comminutor provides means for automatically reversing the rotor on successive operations to prevent clogging of the comminutor. Where a non-self-priming pump is used the comminutor may be mounted below the level of the material suspension to be pumped, and the feed-tube may be in the form of an inverted-U-tube.

Title: Improvements in or relating to self-retarding mechanical percussion fuses for projectiles
IPC: F42C1/04

Abstract: 371,247. Projectile fuzes. SCHWOB FRRES ET CIE, SOC. ANON., La Chauxde-Fonds, and VARAUD, A., 109, Route de Lyon, Geneva, both in Switzerland. July 30, 1931, No. 21816. Convention date, Aug. 7, 1930. [Class 9 (i).] A delay-action percussion fuze is made with two longitudinal bore s symmetrically disposed about the axis of the projectile and containing a striker 4 and a weight 5 both formed with teeth in mesh o n opposite sides with a central pinion 6. The striker 4 bears against a spring 4b, and the parts are normally held at safe by a centrifugal bolt 9 which is itself locked in place by a projection 5b of the weight 5. On impact, the weight 5 moves forward by virtue of its momentum and cocks the striker 4 against its spring ; and the bolt 9 being thus unlocked moves out by centrifugal force. When the projectile has overcome the resistance of the target, and the momentum is almost entirely absorbed, the spring 4b drives the striker 4 forward and the weight 5 backward until the rack teeth of the striker slip away from the pinion 6, whereupon the striker hits the percussion cap 8, which explodes the projectile. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which the pinion is replaced by a rocking lever and the centrifugal safety is differentlly arranged. This subject-matter does not appear in the Specification as accepted.
