Abstract: The invention relates to a novel case for enclosing a short length of at least one elongate substrate, especially a cable splice. The case has a wrap-around body section and end sections comprising deformable sealing members which in use are deformed into a configuration in which an increase in pressure within the case increases the forces maintaining the sealing members in contact with the substrate. Preferably the case includes heating means which is used to heat the sealing members and to activate a hot melt adhesive placed thereon. The cases are particularly useful for encapsulating splices in pressurized telephone cables.

Abstract: A seal between an ingot mould and a base plate or between a head-box and an ingot mould is formed from a pack of flat, flexible strips, for example, of cardboard or aluminium interlinked at spaced intervals along the strips. The joints between any one strip and an adjacent strip next to one face thereof are staggered in relation to the joints between the one strip and the adjacent strip next to the other face thereof. The pack is expanded lengthwise to separate the strips where they are unjoined and form generally hexagon shaped cells and is then placed on the base plate with the longitudinal edges of the strips of the pack on the base plate. The expanded pack is arranged lengthwise into a closed figure corresponding to the shape of the ingot mould. The ingot mould is then placed on top of the expanded pack which is crushed between the ingot mould and the base plate to form the required seal. A head-box seal is similarly made between the top face of the ingot mould and the head-box.

Abstract: A noise suppressor system uses a set of parallel bandpass filters to transform an input signal into a plurality of spectral adjacent band signals. Each band signal may then be substantially attenuated (squelched) by an attenuation-control circuit when it drops below a predetermined noise threshold. All band signals are then summed to reform essentially the original but noise-suppressed signal. Features of the invention include essentially linear control-attenuation circuitry, and ganged input-output manual level controls for dynamic range matching at constant overall gain.

Abstract: The invention concerns a device for recording and reading the itinerary travelled through by a vehicle and in particular an automobile vehicle such as an agricultural machine. The device is adapted to reproduce on an indicator band a trace of the path followed by the vehicle over a given surface so as to enable the operator to follow, with fidelity, in the course of a second passage of the vehicle, the trace of the preceding passage which permits, for example in the case of spraying, a rational treatment of the surface to be treated in strictly parallel strips with no omission or overlapping of zones. The device comprises a programmer constituted by the indicator band which travels at a speed which is proportional to the speed of the vehicle in front of a movable recording element which is controlled by the steering of the vehicle and reacts in accordance with the variations in the steering.

Abstract: A hose tray for storing a fluid fill and drain hose for a liquid transport truck includes a cover having a closed position covering the tray to prevent access to, or accidental loss of, the hose and an open position permitting access to the hose. The tray is mounted on the vehicle adjacent, and extending longitudinally of, the liquid transport tank. The tray includes a safety interlock such that when the cover is in the open position, the truck brake system is actuated to prevent movement of the truck. This prevents movement of the truck such as would tear the hose from the truck drain fitting, causing spilling of the tank contents. This is extremely important, particularly in view of the flammable nature of many liquids transported in tank trucks, and further in view of the expense to repair torn and damaged drain hose and fittings for such trucks.

Abstract: An electromagnetically actuated drum type brake embodying an improved support for the actuating magnet. The magnet is supported by a lever and when energized effects pivotal movement of the lever to actuate the brake. The support between the lever and magnet permits some floating movement of the magnet so as to accommodate for surface irregularities and relative movement between the magnet and the lever as is necessary to effect brake actuation. The support, however, restricts the degree of relative movement between the magnet and lever to acceptable values while transmitting the actuating force from the magnet to the lever. The support comprises an integral tab formed at the outer end of the lever which extends into an aperture in the magnet with sufficient clearance to permit limited movement in several directions. Rotary movement is, however, not restricted by this connection.
