A plurality of such panels may be used to form the sides and ends of an enclosure or container such as a drawer in which case connecting members in the form of corner pieces may be used having two pairs of spigot formations projecting at right angles so as to connect adjacent sides together in addition to bridging the panel members forming each side.

Abstract: The vehicle suspension system includes an axle structure comprising at least one axle, and a vehicle-supporting frame structure. A pair of mountings pivotally support the frame structure on the axle structure at each end of the axle. Each mounting consists of a pair of spring members, located adjacent to one end of said axle, each of which extends between a rigid portion of the axle structure and a rigid portion of the frame structure and comprises a plurality of rigid plates separated in a sandwich-type structure by blocks of resilient material secured to each adjacent plate. The axes of each pair of spring members extend transversely to the direction of travel of the vehicle and are upwardly inclined relative to each other at equal and opposite angles, and each spring member is designed to operate under compression and shear to support the frame structure, but has relatively little torsional resistance so that it operates as a pivotal support.

Abstract: The dust collecting efficiency of a gravel bed filter system in which a plurality of filter modules receive dirty gas from and dischage backflush gas and collected dust into a plenum chamber is enhanced by continuously drawing gas from a downstream end of the plenum chamber, passing the withdrawn gas through a cyclone separator, and returning the gas to the upstream end of the plenum chamber.

Abstract: A kiln car has a wheeled base and a superstructure supported above the base, the superstructure comprising a number of tiers of refractory batts supported one tier above the other by a series of props. At least the lowermost tier of batts is supported on at least some of the props through the agency of discs which each have a convex or domed face so as to make point contact either with a batt or the supporting face of the respective prop.

Abstract: An attachment assembly is disclosed for providing anchorage points in a motor vehicle for attachment of passenger safety restraints such as children seating units and safety harnesses, headrests and such like. The assembly includes a beam and a pair of mountings adapted to co-operate with respective ends of the beam and arranged, in use, to support the beam in a position adjacent the top of a vehicle seat or seats. Each mounting includes an attachment plate to be secured to the vehicle and having flanges forming a mouth for lateral reception of the respective beam end and an apertured box-shaped casing provided on the respective beam end and interfittable with the flanges so as to close the mouth and constrain the beam from movement laterally and lengthwise of the mountings.

Abstract: A plurality of cooling tubes are arranged in planetary fashion about the periphery of the kiln. An inlet for each cooling tube includes a transition member extending from one end of each tube, which transition member comprises the wall of an inclined frustum whose base lies on the end of the cooling tube in a plane perpendicular to the axis of the tube. An inlet tube has one end intersecting the wall of the kiln and its other end intersecting the wall of the transition member, two surface lines of the transition member being tangent to the inlet tube.

Abstract: A stream of raw material is passed through a preheater to a furnace and a stream of exhaust gases from the furnace is passed through the preheater to preheat the raw material. Dust is electrostatically precipitated from the exhaust gases leaving the preheater, and the temperature of such exhaust gases is controllably raised to improve the efficiency of the dust removal by bypassing a controlled proportion of at least one of said streams around at least a portion of the preheater.

Abstract: An elastic surface wave propagation device is disclosed which is composed of a substrate for elastic surface wave propagation and at least one transducer disposed on the major surface of the substrate for converting an electric signal into an elastic surface wave or vice versa.

Abstract: A magnetic video recording and reproducing apparatus has a magazine receiving section for receiving a tape magazine, a rotary magnetic head assembly, and a tape threading assembly that includes a flat annular rotatable member surrounding the rotary head assembly and partially underlying a magazine received in the receiving section. Means including a hook and a roller are provided on the annular rotatable member to engage a tape in the magazine and, as the rotatable member is rotated, draw it around the rotary magnetic head assembly to a position where the tape is pinched between the roller and a capstan and the tape lies against the rotary head assembly in position to be scanned. Guide pins, cam actuated from the rotatable annular member, move into or out of tape engaging positions as the member rotates.

A clamping stud has a clamping head which is engageable in the aperture of the cutting element and has a shaft which is displaceably guided in the hole in the support surface. A control screw is adjustably mounted in the shank beside the shaft of the clamping stud, in operative engagement with the shaft. An annular groove on the surface of the control screw is engaged by the single tooth formed in the shaft of the clamping stud by two milled recesses. The control screw has smooth-walled cylindrical peripheral surface portions on both sides of said groove which are in engagement with the bottom surfaces of said recesses.

Abstract: A cleaning machine for cleaning dirty, greasy or otherwise polluted metal parts comprises a foraminated basket for receiving said metal parts, which basket is rigidly mounted for rotation with a rotatable wheel. The wheel is driven by spray jets from spray nozzles around the periphery of the wheel. The spokes of said wheel have their free ends provided with vanes mounted thereon in a freely swingable position. Within certain limits of the rotation speed of the rotor the vanes are hit by the spray jets. If a specific speed is exceeded, the vanes are swung outwards by centrifugal forces and brought beyond the effective operation area of the spray jets. In the absence of a driving force the rotation speed will go down. In this way an automatic controlling of the rotation speed is possible.
