Patent number: 7736118Abstract: A transfer apparatus includes a stationary base, a swivel supported by the stationary base to be rotatable about a vertical axis, a guide member mounted on the swivel, a linear movement mechanism supported by the swivel or the guide member, a hand supported by the linear movement mechanism and moved by the linear movement mechanism for carrying a work along a straight and horizontal travel stroke, a drive source disposed inside the stationary base, and a transmission shaft disposed along the vertical axis to transmit drive power from the drive source to the linear movement mechanism. The swivel includes an upper section and a lower section detachably connected with each other. The upper section has a connecting member supported by the upper section to be rotatable about the vertical axis. The connecting member has a detachable engagement member for engagement with the transmission shaft from the above.Type: GrantFiled: April 16, 2008Date of Patent: June 15, 2010Assignee: DAIHEN CorporationInventors: Takafumi Uratani, Daisuke Sado, Hideki Matsuo

Patent number: 7695016Abstract: A device and method for steering mechanism breakaway are disclosed. In order to avoid harmful steering column intrusion into the passenger compartment of a vehicle in the event of vehicle collision, an intermediate link between the steering column and the steering gearbox is disposed. The intermediate link comprises of an inner shaft and an outer tube which are connected via longitudinal matching splines to facilitate rotational engagement. In normal operation the inner shaft may longitudinally move inside the tube. The outer tube has openings along it and detachment means at one end to facilitate detachment of the shaft from the tube through the openings when the shaft moves longitudinally into the tube beyond a certain point due to movement of the steering gearbox towards the steering column during a collision.Type: GrantFiled: September 12, 2007Date of Patent: April 13, 2010Assignee: Tata Motors LimitedInventor: Vinayak Gogate

Publication number: 20100014913Abstract: A spline structure, in the form of an aeronautical brake drive bar, has wheel attachment points at its ends for engaging a wheel rim. Each wheel carries a regularly spaced series of these drive bars for engaging friction discs carried by the wheel hub. The main body of each brake drive bar is formed from titanium internally reinforced by composite blocks each comprising a bundle of silicon carbide fibres contained in a matrix that is diffusion bonded within the main body. Other spline structures can be formed in a similar manner.Type: ApplicationFiled: May 31, 2007Publication date: January 21, 2010Applicant: TISICS LIMITEDInventors: David Philip Murgatroyd, Stephen Mark Flitcroft, Renny Neil Moss, Stephen John Kyle-Henney
