Abstract: A locking switch for electrical automobile systems connects and disconnects an automobile battery to the starter. The locking switch has two normally separated contact plates, one connected to a cable from the battery and the other being connected to a cable from the starter. A lock cam is mounted at the end of a cylinder lock, which is key-actuated. The lock cam carries a spring-loaded copper ball that rotates with the lock cam upon actuation by the key. The cam and ball can be moved from an open position on one stationary contact to a closed position, whereby the ball provides electrical contact between the two stationary contacts, thus completing the electrical circuit between the battery and the starter. Each stationary contact is provided with a semispherical indentation in which the ball is received in the open position, thereby providing a substantial contact area between the ball and each of the two stationary contacts.

Abstract: A horizontal mixing aerator rides on a upright mast or beam for submersion in a body of liquid such as a sewage equalization basin, oxidation ditch or sludge holding tank. The aerator has a submersible mixer motor driving a propeller which is mounted to the beam by a slidable bracket arrangement for height adjustment. The bracket is also swingably mounted to the beam for adjustment of the vertical plane angle and the beam is rotatable for azimuth changes in the direction of liquid flow. A lower bracket stop includes vibration reducing elements. An upper azimuth lock also includes vibration reducing elements. The locking parts have a high co-efficient of friction.

Abstract: A clip apparatus for use in cholangiography or the like includes a clip, a catheter and a tool for applying and removing the clip from the cystic duct or the like. The clip preferably has two opposed C-shaped surfaces in jaws which can be biased together such that opposed edges touch to apply the clip or spread apart such that at least one set of opposed edges is spread to allow removal of the clip. The clip includes arms attached to the jaws which are medially bent outward at the time the clip is applied and which are compressible to rotate the jaws relative to one another about a common fulcrum to space sides of the jaws opposite the fulcrum and allow easy removal of the clip. The catheter is inserted in the cystic duct during a cholangiography procedure and held therein by the clip. The catheter is serrated on the surface thereof which engages the duct beneath the clip.

Abstract: A vehicle alignment system uses transverse, longitudinal and vertical bars mounted on a vehicle and equating to X, Y and Z axes for establishing the dimensions of the vehicle, which dimensions are then compared to the vehicle engineering specifications. The transverse bars are connected to the underside of the vehicle and, to enable quickness and ease of transferring the alignment system between vehicles, quick connect fittings extend between the transverse and longitudinal bars. Additional supports extend between the longitudinal bars and a base surface. The system is arranged so that transverse bars in a path of entry and exit of the vehicle can be readily removed and the vehicle removed and replaced, while maintaining the alignment system substantially set up and ready for use. The process improves the speed of use of the system by substantially alleviating the dismantling previously required.
