Abstract: Cryogenic fluids are delivered along an axial path through a machine tool spindle to a cutting tool that is mounted in a standard tool holder. An external source of cryogen is delivered via an insulated line to a junction block housing where the cryogen flows into a vacuum insulated coolant delivery tube mounted on the axis of rotation of the spindle. The coolant delivery tube couples with a cryogenic manifold located in a standard tool holder in the end of the spindle. The cryogenic manifold couples the cryogen to a tool that is mounted in the tool holder. Before a tool change operation, the coolant delivery tube is raised to disconnect it from the cryogenic manifold, and to turn off the flow of cryogen to the delivery tube.

Abstract: A handle arrangement on a vacuum cleaner hose has an inner bushing non-rotatably attached to one end of the hose and is inserted in a handle tube and axially fixed therein such that it can rotate. Electrical leads are guided outwards from the hose and the inner bushing in a radial direction through a wall opening of the handle tube and into the cavity of a handle part. The handle part is firmly connected at both ends to the handle tube. The electrical leads are fixed so as to form a length reserve loop in the cavity. A receiving space is provided on the inner bushing, into which electrical leads from the length reserve loop are shifted when relative rotations take place between the hose and the handle tube. The possible rotation angle is delimited by stops according to the lead length available in the length reserve loop.

Abstract: A retainer arrangement that includes a retainer for retaining a hinged arm on a vehicle in a stored position positively so that the hinged arm does not move away from the vehicle unintentionally. The arrangements may be used in connection with a hinged stop arm that is attached to the side of a school bus that is deployed when the school bus stops to pick-up or drop off passengers.

Abstract: A modular electrical bus system has a grounding circuit through a plurality of modular I/O units with each unit being both electrically and mechanically connectable together via a bridge member connecting adjacent units and the main communication module. The bridge member and modular I/O units are grounded together with a ground circuit that extends within both components.

Abstract: A playing card apparatus and method for discreetly displaying values on faces of playing cards while in a face down orientation to a player. The apparatus has a housing with a playing card support surface with an opening over which the playing cards are placed face down. A first mirror is positioned below the opening to reflect an image of the playing card values in one direction while in their face down orientation. A second mirror is positioned below the opening to reflect the image from the first mirror upwardly through the opening for discreet viewing by the player.

Abstract: A hat rack for a vehicle includes a basic member. The basic member consists of at least one dimensionally stable support, which has mountings for a variety of functional parts. The dimensionally stable support advantageously can be bolted to the body of the vehicle and thereby impart great strength, in particular great torsional strength, to the body in the installation region.

Abstract: A retractable mirror assembly for a vehicle which retracts towards and extends away from a vehicle body wherein the mirror compensates for the change in position so that the same perspective is maintained. The mirror assembly comprises the vehicle body in which a mirror housing that surrounds a mirror backing plate having a mirror glass is retracted and expanded to and from the vehicle body. A second support bracket and a stationary bracket are connected and move in relation to one another in order to rotate the mirror backing plate and mirror so that the mirror maintains the same perspective while the mirror assembly is being retracted and expanded to and from the vehicle body.
