Title: Method and a railway train for draining a railway track
IPC: E01B27/02
Filed: 1980-09-03
Abstract: A method for the improvement and drainage of a length of railway track employs a train to carry out the method whereby it is made possible to dismantle and reassemble the length of track together with its infrastructure. Ballast and earth are excavated from the track and replaced by a layer of sand which is distributed and compacted mechanically through an empty frame of a working truck of the train. Two travelling gantries are provided on the train and equipped both with a lifting device for a length of track and a lifting and tipping device for buckets. The working truck is also equipped with a strip for levelling a platform and a tamper. These two members are mounted on a common chassis supported by travelling on the two side parts of the empty frame of the working truck within the travelling supports for the gantries so that the levelling-tamping chassis may move freely by passing below the gantries.

The light may return by the same optical conductor 5, in which case an optical divider (not shown) is provided at end remote from material 1. Alternatively the light may return by an adjacent optical conductor, in which case there is used an optical switching arrangement (Fig. 3 not shown) or a multiplexing arrangement (Fig. 5 not shown). The colour may be compared with a desired colour strip (29) and the information processed and displayed by a processor (28). The processor may also automatically control the printing apparatus. <IMAGE>

Title: Pivoted Fitting for Seats
IPC: B60N2/235
Filed: 1981-02-09
Abstract: The fitting comprises a bottom fitting part (1) and a top fitting part (2) interconnected by a pivot joint (3). The top fitting part is provided with a toothed segment (4) which cooperates with a toothed part (5) fixed to the bottom fitting part and operable by a handle (7) and means for automatically locking the fitting in case of shock. The bottom fitting part has arranged thereon a gear-wheel (8 Figure 2, not shown) which meshes with the toothed segment, is rotatable about a shaft (9, not shown) and carries at least one latching hook (16). Each hook is pivotable about a pivot shaft (15) arranged eccentrically on the shaft and loaded to an inwardly swung position by a spring (18). The bottom fitting part has arranged thereon a latching projection (19) the distance of which from the shaft is greater than the turning circle of the latching hook(s) in the inwardly swung position but smaller than the turning circle of the hook(s) in its outwardly swung position. In operation, should the hooks (16) swing outwardly into the position shown by the broken lines in Figure 1 under the influence of a rotational movement and of a centrifugal force resulting therefrom, their latching regions are latched on the projections (19) and the rotational movement is arrested. <IMAGE>

Title: Improvements in water tables for use with burning machines
IPC: B23Q1/03
Filed: 1981-02-26
Abstract: A water table for use with a burning machine comprises an open-topped water tank 1, a burning platform 4 extending across at least part of the tank, and support means for the burning platform 4, which support means are adjustable vertically, for example hydraulically, in a manner to vary the level of the burning platform with respect to the surface of water in the tank. Thus by vertically adjusting the position of the burning platform the workpiece carried by the platform may be positioned below, at or above the surface of the water, and the burning platform may also be raised to a convenient height for positioning or removal of the workpiece. A sloping floor 6 is provided beneath the burning platform so that, as the platform is raised, the downward flow of water over the floor cleans it of slag which has fallen through the burning platform. <IMAGE>

Title: Construction of in situ piles
IPC: E02D5/38
Filed: 1981-03-09
Abstract: Tubular means comprises a tip member (11) having a closed leading end (13) and a number of trailing tubes (12) connected in longitudinal alignment. The tubular means is driven down by the action of both a self-propelled mole (16) received within the tubular means and acting on the tip member (11) and by a vibratory hammer (19) acting on the upper end of the upper-most tube (12). The aim is for the mole to provide the force for soil displacement and the hammer to provide the force for overcoming the increasing skin friction as the hole deepens. Concrete may be poured to form a pile in situ in the hole during or after withdrawal of the tubular means, or the tubular means may remain in situ to enable formation of a cased pile. <IMAGE>

Title: Anti-skid modulators in hydraulic braking systems
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/40
Filed: 1982-10-12
Abstract: An anti-skid braking system incorporates a modulator assembly (3) through which fluid from a source (2) is supplied to a brake (1). The modulator assembly (4) comprises a de-boost piston (7) working in a bore (6) in a housing (5), an expander chamber (8) connected to the brake (1) and defined in the bore (6) between one end of the piston (7) and a first valve (9), and a second valve (11) for controlling the application to the piston (7) of support fluid to determine the relative position of the piston (7) in the bore (6), the second valve (11) being manipulated in response to a skid signal. The first valve (9) is normally biassed in to a fully open position, and the operation of the first valve (9) is controlled independently of the piston (7). An inhibit device (15) is incorporated to ensure that at the termination of a skid signal first valve (9) is maintained in a closed position at least until the piston (7) has returned to an advanced position in which the effective volume of the expander chamber (8) is at a minimum value. <IMAGE>

Title: A shuttleless loom having a gripper rod
Inventor: RUPP WILHELM
IPC: D03D47/27
Filed: 1982-11-22
Abstract: In a shuttleless loom (Fig. 1) which includes a weft thread insertion device having a gripper rod (2), the rod reciprocates into and from a protective tube (1). Within the tube troublesome vibration of the free, rear end of the gripper rod can occur and this vibration can be transmitted forwards to the gripper head (3) where it may prevent proper transfer of the weft thread. To prevent such vibration, a guide element (7) is arranged at the rear end of the rod (2), which element (7) slides back and forth inside the tube (1), for example in the manner of a piston. <IMAGE>

Title: An apparatus for bending metal beams
Inventor: SLATTERY WILLIAM
IPC: B21D7/022
Filed: 1982-12-23
Abstract: The invention relates to arches for use in tunnels such as underground mine tunnels. These arches are composed of a bent metal beam often of "H" or "T"-section. Problems have previously arisen in accurately bending the beams to the required shape. The apparatus of the invention includes a D-shaped former (2) which is rotatable relative to a roller (14). The beam (18) is clamped to one end of the former and on rotation of the former relative to the roller, the beam is bent around the former so that it assumes the required shape, the ends of the beam being clamped to the former by clamps (20). One portion (26) of the former is movable relative to the rest of the former so that at least the end parts of a beam (18) bent around the former are stretched. A cutting device may be employed to cut the beam, whilst bent around the former, into three or more sections. <IMAGE>

Title: Automatic flushing system for a urinal
Inventor: ETTER BRUNO
IPC: E03D5/10
Filed: 1983-01-05
Abstract: A control device (6) detects the electrical conductivity of the fluid located in the outlet trap (2) of the urinal (1) by means of two probes. When, during use of the urinal, the conductivity exceeds a predetermined value, the control device (6) initiates a delay period. After this period of time has expired, the control device (6) opens an inlet valve (9) in the water supply pipe (4), whereupon the flushing tank (3) is flied with water. The discharge valve (5) initiates the flushing operation as soon as a predetermined water level is reached in the flushing tank (3). The control device (6) closes the inlet valve (9) when the conductivity of the fluid drops below a predetermined value. The flushing operation is terminated after the flushing tank (3) has been emptied. <IMAGE>
