Abstract: The device for locking the manual control lever (14) of an electrical appliance such as a switch comprises two adjacent portions (1) pivotally joined together by means of a hinge portion (2), fastening means (3) each extending along an edge portion located in spaced relation to the hinge portion (2), at least one bearing surface (4) provided on one of the adjacent portions (1) and at least one locking orifice (5) formed in each adjacent portion and so arranged as to come into position in register with the corresponding locking orifice (5) of the other adjacent portion (1) when the device is in the locking position. The device can then be maintained in the locking position by the shackle of a padlock engaged in one of the orifices (5) or by a lead-sealed wire.

Abstract: Disclosed is a detent mechanism for use in a control with a sliding lever, in which the lever is slid to desired operation positions, such as for example, a slide switch or a volume control of a radio. In the detent mechanism, a slide guide is formed with a series of cam crests. Fixed to the sliding lever is a spring member which carries a roller at its leading end which engages with and rolls on the cam crests.

Abstract: A method and apparatus of collecting a desired end-point weight amount of material first conveys the material into the collection container until a predetermined weight amount is collected. The predetermined weight amount is less than the desired end-point weight amount by a selected initial weight offset amount. An additional incremental amount of material is next conveyed into the container for a predetermined fixed time period. In doing so, the method and apparatus gauge the particular flow characteristics of the associated flow system. A further additional incremental amount of material is conveyed into the collection container for another time period, the length of which reflects the anticipated flow characteristics of the system, based upon the performance of the system during the preceding period. The method and apparatus repeat this sequence until the then-existing weight amount equals or exceeds the desired end-point weight amount.

Abstract: Each filling station comprises a balance (36) and a piston and cylinder volumetric dispenser (37). The piston rod (33) is actuated by a cam (34) which optionally includes a portion (341) which is adjustable. Resilient means (40) are interposed between the cam and the piston. While a receptacle (39) is engaged in a filling station the following operations take place in succession: the empty receptacle is weighed and at the same time the volumetric dispenser is filled with slightly more material than is to be dispensed; the material in the volumetric dispenser (37) is then transferred to the receptacle (39) and the receptacle is continuously weighed until it has received the set weight of material. The outlet from the dispenser is then closed, thus jamming its piston before it reaches the end of its stroke. The resulting forces are absorbed by the resilient means.

Abstract: A structural assembly, more particularly for a shower partition, comprising a sectional rail having, in one of its outer surfaces, an undercut first channel of which the sides form two lateral grooves. Inserted into this channel, is a facing panel, a resilient connecting element being provided for retention and engagement in the grooves. In order to obtain a structural assembly of small depth, together with reliable and rapid attachment, the facing panel is provided with a longitudinal second channel extending in the direction of its longitudinal axis and undercut along the channel sides to form grooves. The connecting element is arranged at least partly in the second groove where it is held by the undercut second grooves. The connecting element has a lateral projection which extends into one of the first grooves of the sectional rail. Projecting into the other groove of the sectional rail is either a shoulder of the facing panel or a second lateral projection of the connecting element.

Abstract: A drainer container and funnel having a container with an elongated internal receiving chamber that is defined by a pair of opposed major walls and at least one minor wall that interconnects the major walls, and a funnel that is detachably attachable to one of the major walls. The wall to which the funnel is attached is provided with an inwardly recessed funnel receiving wall portion and an aperture therethrough at an innermost part thereof. The funnel has a spout portion that is detachably connected to the recessed wall portion in such a manner as to communicate with the internal chamber of the container through the aperture, and the funnel being of a size and shape so as to be substantially entirely received within the recessed wall portion of the container when connected thereto. When the funnel is detached, a closure seals the aperture in the recessed wall portion.

Abstract: A thermally insulated storage or transport vessel for low-boiling point liquefied gases comprises a rigid self-supporting inner receptacle or tank and a nonself-supporting outer container. The outer container, formed from a pair of longitudinally spaced opposing rigid end shells interconnected by an intermediate shell provided with stiffening formations extending peripherally of the intermediate shell. The intermediate shell is longitudinally expansible or contractile and may be formed with angular-section or curved-section corrugations.
