Title: Subsurface safety valve for wells - provides full opening through it and allows closure member operating parts to be retrieved without pulling string
Inventor: AKKERMAN NEIL HOOVER
IPC: E21B23/03
Filed: 1982-06-28
Abstract: Valve has a mandrel with a through bore having an axis aligned with the tubing string axis when it is connected as part of the string. There is a pocket to one side of the bore which has an end which opens into the bore and a closure member is mounted in the mandrel which is yieldably urged to its closed position. A tool can be moved vertically through the string and open end of the pocket into and out of a landed position within the prod. It is responsive to the supply of control fluid to it, when landed in the pocket, for opening the closure member. The control fluid is supplied from a remote source. The valve has the advantages of both the tubing mounted and the wire line retrievable type, in that it provides a full opening through it, while, at the same time, permitting at least some and pref. all of the parts for operating the closure member to be retrieved and repaired or replaced without pulling the entire tubing string.

Title: Method and device for enhancing the accounting security of machines distributing coupons such as transport tickets
Inventor: PAILLER ALAIN LOUIS
IPC: G07B5/08
Filed: 1982-09-14
Abstract: In order to enhance the accounting security of a machine distributing a ticket made from a coupon 11 on which are written data corresponding to a selected value, on each virgin coupon a recognition code is inscribed which is stored in memory during the time it takes to print the ticket. The selected value is counted up in a receipt counter. In the case of an operating anomaly necessitating cancelling the uncompleted ticket, the latter is reinserted into the machine 10. The recognition code inscribed on the coupon 11 and the code value placed in the memory are then compared. If they agree, the content of the receipt counter is decremented by the selected value.

Patent FR-2535780-A1 (FR)
IPC: E21B4/14
Filed: 1982-11-04
Abstract: Device enabling to impart simultaneous rotating and striking motions to the bit of a drilling head, the drive force required for the latter motion being transmitted through liquid distributed through the drill pipes down to the drive elements arranged in the lower drilling head. The drive elemements are comprised of a turbine (16) supplied with said liquid and driving a hydraulic pump (17) which indirectly actuates, through a distributor (35), the hammer (22) which strikes the shank (27) of the bit (2). Said elements being distributed in two chambers sliding one on the top of the other, said sliding motion being used to stop the striking motion when the device is hanging and to start again the striking motion as soon as the device bears at the bottom of the drilling hole. The invention may be used for any deep drilling or for any drilling in rocky ground or even mellow or water-bearing ground.
