Title: Improvements in Tipping Bodies for Vehicles.
Inventor: LLYOD GUY ERNEST
IPC: B60P1/32
Filed: 1918-06-03
Abstract: 129,755. Lloyd, G. E. June 3, 1918. Tipping-wagons of the kind in which the body is slid laterally until it overbalances have both the sliding and tipping movement limited by chains or sliding or folding links. The construction shown comprises a front and a. rear body or tray a, beach having a pair of rails 2 normally resting on rollers 4 mounted in fixed brackets 5. Two pairs of chains 12, 13 attached to each tray and to the chassis limit the sliding and tipping movements respectively, according to the side to which the tray is tipped. Sideways movement of the tipped tray may be checked by arranging the points of attachment of a pair of chains to the tray at a greater or less distance apart than the points of attachment to the chassis, so that the chains are not parallel. The trays may be locked in the normal position by a bar 10 secured to the underside thereof and adapted to be fastened to the chassis, as by a removable pin 11. Or the trays may be raised off the rollers so as to avoid unnecessary wear of the rails and rollers, and at the same time be held from movement by arms 16, Fig. 6, on a transverse rock-shaft 15, which arms are adapted to engage shoes 17 fixed to the rails 2. The trays may have removable sides 6, the fastening-means comprising irons fixed to the ends and adapted to engage notches in the rails 2 and pins 7 on the fixed sides. The trays may have floors of timber or corrugated sheeting lined with plain sheeting curved upwardly at the corners of the tray to facilitate the sliding-off of the material when the tray is tipped. In a modification, the rollers are mounted on the trays, and telescopic links replace the chains.

IPC: G01N15/06
Filed: 1970-02-25
Abstract: 1,274,634. Separating and detecting components of gas mixtures. FRANKLIN GNO CORP. 25 Feb., 1970, No. 9173/70. Headings B1L and B1X. [Also in Division H1] Components of gas mixtures are separated and/or identified by causing a selected component to be ionized by interaction with other ions, and then applying a suitable drift field to separate the selected component. Thus the effluent from a gas chromatography column 86 (see Fig. 3) is passed by duct 12 together with a reactant gas such as O 2 , SO 2  or a fluorocarbon to cathode chamber C where the reactant gas is ionized by means not shown. These ions interact with the effluent component, ionizing the components in turn. These ions to be detected pass through grids G 1 , G 2  to gating grids G 3 , G 4  variably arranged so that gates G 3 , G 4  open in such time sequence as to permit only one selected component at a time to pass through to anode A for detection by electrometer 20. In another embodiment (see Fig. 4) employing only two grids arranged longitudinally in air conduit 88, trace vapour M is ionized by interaction with oxygen ions formed in the left-hand part of the conduit between electrode 92 and grid G 1 . The M- ions drift downstream and across the conduit, pass through grid G 2 , are discharged by electrode 94 and pass from conduit 88 in a concentrated stream through pipe 98. In another embodiment (see Fig. 2, not shown), the ions which have passed through grid gates are detected optically by causing aerosol nuclei to condense about the ions. Details of suitable gating circuitry are given.

Abstract: 769,740. Writing instruments. KOVACS, T. April 5, 1955 [April 30, 1954], No. 9923/55. Class 146(3). A pen or pencil has a writing unit, e.g. a ballpoint pen 6, which falls freely between abutments in the barrel 1 and a latch which holds the pen 6 in writing position under the influence of a weight 12 arranged to fall axially in the barrel, relative to the pen 6, between abutments, the latch having parts radially displaceable by the side wall of the dropping weight to engage a shoulder 19 in the barrel for supporting these parts in radially displaced position. When the pen is held in the position shown in Fig. 1, the pen 6 drops into engagement with an abutment 39 due to the weight 12 dropping on to an abutment formed by a carrier 8 for the pen, such that the point 20 projects beyond a nose piece 4 screwed into the barrel 1. The front conical portions 13 of the weight 12 forces balls 17, forming the radially displaceable latch parts, into engagement with the shoulder 19, thereby locking the pen 6 in writing position. When the pen is held in point upwards position the weight 12 drops on to a flange 10 forming an abutment and then the balls 17 disengage the shoulder 19 allowing the pen 6 to drop until a flange 11 on an extension tube 9 engages,an internal flange 21 of a sleeve 2. The pen 6 is held in retracted position by a catch 23 fitted in a groove 22 of the sleeve 2 and engaged by a spring 24 which presses a nose 25 on the catch 23 into engagement with flange 11. The nose 25 is released by a stem 26 extending through the barrel. The pen 6 may be given a slight rotation whilst being brought into writing position by fine notches on the abutment 39 and the lower edge 40 of the carrier 8.
