Abstract: A low profile motor-driven transport trolley including a frame upon which a rotating plate may be mounted. The frame is supported by sets of wheels disposed on opposite sides thereof and hydraulic motors are provided to power the sets of wheels separately to obtain a differentiated drive. The motors are hydraulic and are fed by a pump to thereby control motion of the sets of wheels.

Abstract: A filling or replenishment unit is mountable on a first toothpaste tube used for travel ‘travel tube’ and may be moved to extended position to establish communication with a second tube to allow refilling of the first tube from the second.

Abstract: An RF roadway toll collection system uses an upstream reader to communicate with a vehicle borne transponder carrying a Smart Card to calculate the toll and debit the Smart Card balance in the amount of the toll payment required. A transaction manager is notified of the toll payment from the upstream reader and notifies a downstream reader of the vehicle identification and payment status. The downstream reader confirms the vehicle identification and payment status and signals if the toll has been paid.

Abstract: The invention concerns a method which consists in: pre-positioning, in a housing (7) of a flange (5), a bucket (2) supported by part (23) of its outer surface (23) against an edge (71) of the housing (7) providing a space (E′) between the convex surface (23B) of the outer radial part (2B) of the bucket (2) and said edge (71); producing an articulated linkage (15) of the bucket (2) on the rim (1) and/or the flange (5) on the inside (2A) of the bucket (2); exerting on the outer radial part (2B) of the bucket (2) a first calibrated force to bring it closer to the edge (71); determining the distance (e) between said outer radial part (2B) and said edge (71) under said force; slackening said force; arranging, between said outer radial part (2B) and said edge (71), a wedge (53) having a thickness substantially equal to said distance (e); and exerting on the outer radial part (2B) of the bucket a second force (F2) to bringing it closer to the edge and maintaining said second force (F2) which has an intensity n

Abstract: An intumescent powder where the molar ratio of SiO2 to Li2O+Na2O+K2O is between 2.20 to 3.70 to 1.00 and the molar ratio of Li2O to Li2O+Na2O+K2O is 0.20 to 0.35 has an intumescent point of 195° C. or higher and thus will not prematurely intumesce if mixed with another material at temperatures below 195° C. The powder as used is usually dried to 8-12% by weight to moisture for most purposes is ground to 50 to −500 microns. Preferred methods of manufacture comprise taking a source of lithium hydroxide or lithium silicate and a source of sodium silicate to create a powder with ratios as outlined above.

Abstract: A bracket for supporting an open wire channel for cables or the like wherein the bracket is formed from a sheet of metal and includes a part for supporting the channel and first and second clip members for laterally holding the channel and which clip members extend upwardly beyond the supporting part on opposite sides thereof and which clip members are secured by elastic deformation relative to sides of the channel.

Abstract: The problem of losing throttle control when controlling an AC motor throughout transmission shifts has been solved for a finite set of discrete waveforms. The solution requires making as many discrete speed waveform tables as there are gear ratios in the transmission. Each table has speed entries appropriate for controlling acceleration and deceleration while in its selected gear ratio. In addition when a new gear ratio is selected a transition to the new table with a changed motor rpm can be done with the throttle unchanged. This provides a smooth control for both manual and automatic transmissions.

Abstract: A floor pocket assembly for use in securing a load to a vehicle floor. A pair of slightly spaced coaxial circular plates are bolted to the floor and a connector is snapped over the top plate by a U-shaped member on one planar side thereof, and held in place by a spring loaded pin which extends into the bore of the two circular plates.

Abstract: A device for silencing a flowing gas which includes a valve housing in which a valve is mounted. A separate pressure regulator is provided which is in communication with the flowing gas and which is responsive to gas pressure to thereby influence movement of a mechanical actuating device which controls movement of the valve such that the valve may be opened at least two different rates dependent upon the pressure of the flowing gas.

Abstract: A prosthesis of the upper extremity of the humerus of the type that comprises a stem anchored in the humeral canal and provided on its upper or metaphyseal part with a bearing surface against which rests a hemispherical cap suitable to interact with a shoulder socket, wherein the stem is selected from a set of stems each provided with a bearing surface having a tilt angle that differs with respect to a longitudinal axis of each stem. A set of humeral stems comprises several stems each of which is provided with a bearing surface having a tilt angle that differs with respect to the longitudinal axis of each stem.

Abstract: A female element of a quick connection for removably joining two pipes through which a fluid passes wherein the element includes a body defining a housing for receiving a portion of a male endpiece. A retaining device is operable to selectively retain the endpiece in fitted configuration in the female element and includes a push-button which carries a lock for selectively locking the endpiece in the housing or for preventing the introduction of the endpiece in the housing.

Abstract: A loudspeaker system of improved clarity, coherence and uniformity of energy distribution containing mid frequency sound chambers with an annular input and approximately rectangular output for use in multi-way co-axial horn loaded line array systems. The sound chambers propagate the annular mid frequency sound wave co-axially with a high frequency sound wave, gradually changing the cross section of the mid frequency wavefront resulting in co-linear acoustic mid and high frequency wavefronts from multiple devices which range from the shape of a flat ribbon to that of a curved ribbon. The sound chambers may be arrayed contiguously and placed at the entrance of a suitable waveguide to form a wide band width acoustic line source of extended length and controlled beamwidth.
