Abstract: The invention refers to a device for supporting and carrying e.g. a centrifugal rotor (1). For making possible an adjustment of the rotor thus that any possible unbalance is eliminated as far as possible, the rotor is supported upon a supporting element (2), on which it is radially displaceable. Between the rotor (1) and the supporting element (2) is provided a bearing part (3). This is rotatable and displaceable laterally on the supporting element (2) and carries the rotor (1) with means, which incorporate deformable members (9), which allow a tilting of the rotor (1) upon the bearing part (3).

Abstract: A multiple support for test tubes which receives a plurality of individual tubes for a gas sample to flow through simultaneously at at least one openable end of a connecting piece which has a flow outlet, the receiving devices provided for this purpose having at least in part a restrictor element in order to achieve a uniform flow, is to be improved in such a way that sealed test tubes can be inserted in it and these are all prepared simultaneously for a gas sample analysis without having to interrupt the rest of the gas conveyance flow. It is only to be capable of being opened in the installed state. For this purpose provision is made for the connecting piece (8) to have, at its connecting side (12) facing the test tubes, perforations (13) with which the ends of the test tubes, which are provided with a membrane closure, and are held in a crosspiece can be pierced to produce a flow connection. <IMAGE>

Abstract: A time switch with a dual structure-type control memory utilizing a time division time switch. The switch is equipped with a speech memory unit into which digital signals to be interchanged are temporarily written, and a control memory unit into which addresses to be accessed by the speech memory unit are written. The control memory unit has first and second memories. Each memory has an input/output section connected to a memory controller. The memories are set during hard and soft cycles so that when either one of the memories is set in a hard cycle the other memory is set in a soft cycle. The hard cycle is a speech-control data read-only mode. The soft cycle is a speech-control data read-write mode under control from the corresponding memory controller.

Abstract: A plastic squeeze bottle (11) has a dispensing end (12) having a central, closed-ended, cone-shaped portion (21) which serves as a stem or core for a valve assembly which includes an elastomeric seal (31) which overlies and resiliently grips and circumferentially seals around the stem (18). The seal (31) also covers apertures (22) in the bottle end adjacent the stem (18). A small central aperture (37) in the seal (31) where it overlies the closed end of the stem (18), enables dispensing contents from the bottle (11) when the bottle (11) is squeezed, as the resulting internal pressure causes the seal (31) to balloon slightly away from the stem (18) and permit passage of saline solution from the bottle (11) through the bottle end apertures (22) and seal central aperture (37). When the squeezing stops, the seal (31) resiliently retracts against the stem (18) and closes the bottle (11). A snap-on overcap assembly (17) has seal control and closure maintenance features (53, 54) to avoid accidental dispensing of bottle contents due to unintentional squeezing of the bottle (11) when the overcap (17) is closed.

Abstract: The invention relates to electroweldable sockets. Previously the predominant method of manufacture has been by injection moulding which whilst producing a socket of acceptable quality it is expensive and relatively slow. The objective of the invention is to provide an alternative method of manufacture that is relatively inexpensive and relatively quick and yet does not sacrifice quality, which objective is met by a method comprising winding a length of electrical resistance wire (10) on to a transversely-split bobbin-type mandrel (2), leaving the ends (11) of the wire upstanding from the body part of the mandrel, passing the mandrel through the head (6) of an extrusion plastics processing machine to deposit plastics material (17) around the body part of the mandrel between the flanged ends, and to leave exposed the ends of the wire passing through the wall of the socket exposed, and removing the split mandrel from within the socket after it has emerged from the extrusion head, leaving the winding of resistance wire embedded in the surface of the bore of the socket.

Abstract: A shoe, which is adapted for a particular type of activity, such as running, is provided with a flexible resilient member (13) interposed between an outer sole (12) and an inner sole (16) for storing and releasing energy during each running step. The flexible resilient member (13) is arranged to flex in the region of the ball of the foot of the wearer. whereby as the foot is flexed, energy is stored in the flexible resilient member, and as the foot leaves the ground, the flexible resilient member restores itself to its resting condition while releasing the stored energy in a manner which assists the running motion of the wearer,. The flexible resilient member may be formed of a fiber reinforced polymeric material, such as carbon fiber reinforced epoxy which has a directional flexure characteristic. A plurality of such direc­tional layers of the material may be bonded to one another, so as to achieve a desired overall flexure characteristic which may have different longitudinal and transverse components. The flexure characteristic may be adapted for various wearer weights and running styles, as well as for characteristics of running surfaces.
