Abstract: In a lighting system, comprising a cable with accessible electrical conductors, a holder to be clamped on the cable, and a lamp holder with lamp, the lamp provides a force via the lamp holder to the conductors to make an electrical contact therewith. Preferably the cable has a substantially H-shaped section with cavities that partly enclose the conductors. The holder preferably has a substantially U-shaped section, with legs clamping around the cable. The lamp holder is formed by a pair of contact springs, which are pivotably mounted in the holder, to make at one end contact with the conductors and at the other end to contact the lamp.

Abstract: A delivery nozzle is connected to the outlet end of a fuel supply hose and includes an outlet pipe. A valve is operatively associated with the discharge end of the outlet pipe for opening and closing the latter and an operator is provided for closing the valve responsive to the operator being subject to sub-atmospheric pressure. Further, sub-atmospheric pressure generating structure is operatively associated with the valve operator and generates sub-atmospheric pressure responsive to fuel flow through the outlet pipe and the discharge end of the pipe being submerged within rising fuel in a tank or a tank fill neck into which fuel is being discharged from the outlet pipe.

Abstract: A hose storing apparatus comprising a casing housing, a fuel supply connection, a flexible hose connected to the fuel supply connection at one end and the other end is provided with a nozzle storable in the casing. The casing is divided at least partly into two compartments, each containing at least one loop of the hose. The loop of the hose in the first compartment accommodates a counter weight in the form of a freely movable disc. At the top of the casin, there are further provided a plurality of relatively small rollers in arcuate formation so that in their totality the formed arc crosses above the two compartments.

Abstract: A coupling piece for coupling two or more rods or the like, use being made, for connecting the coupling piece to a rod, of a connector rotatably connectable to said coupling piece, the other end of said connector being adapted for coaction with a rod end by means of a threaded connection. The connector is adapted, through a polygonal outer circumferential portion, to coact for rotation with a ring having a corresponding internal polygonal portion and being provided with external engagement surfaces.

Abstract: Apparatus for Levelling a surface, such as a table, includes several bellows containing a fluid connected to the surface, conduits connecting the bellows together and a control valve for connecting or disconnecting the conduits, the control valve being located in a chamber and being separated from an actuator by a diaphragm.

Abstract: A table comprising two or more legs, at least one leg being fitted with a height adjustment mechanism, all legs being fitted with adjustment mechanisms that are adjustable both in separate and in interconnected relationship.

Abstract: A stacking element comprising interconnectable panels, each consisting of at least two wires or bars bent in the plane of the panel, said wires or bars being interconnected with interposition of at least one wire or bar bent in the shape of a U, substantially projecting at the bottom from the two wires or bars bent in the plane of the panel. On the upper elements there may be provided set and/or floor portions which may be fitted at the top with recesses or the like for mounting chairs thereon.

Abstract: A bicycle frame, having the usual front fork, back fork, steering head sleeve and pedal shaft sleeve has an oblique tube, extending towards the steering head sleeve, which is pivotably connected to the back fork and is substantially in alignment with the back fork. A bar extends from the pivot point towards a saddle support means, and a bar extends towards the pedal shaft sleeve. The bars are substantially in alignment and are being connected to the back fork and to the steering head sleeve by tensioning wires, by demountable and releasable insert and wiring connections.
