Title: Arrangement with a dental screw pin and a clamping device for supporting the pin
Inventor: SUTTER FRANZ
IPC: A61C5/08
Filed: 1984-10-11
Granted: 1987-05-14
Abstract: An axially extending screw pin to be screwed into a tooth has a threaded part and an engagement part with a slot in one end. The slot extends in the axial direction of the pin toward the threaded part with the axially extending surfaces of the slot converging inwardly toward its base which has a concave, semi-circular surface. The converging sides are convex surfaces defining a quarter arc of a circle. A driven member with an engagement projection at one end shaped complementary to the slot, is disengageably connectible with the screw pin. A gripping member is axially displaceable positioned on the engagement projection end of the driven member. The gripping member is freely rotatable relative to the driven member and has resilient gripping tongues for holding a screw pin relative to the driven member. The driven member is mounted in a drive member so that is can be rotated about its axis. With the screw pin held by the gripping member, the engagement projection is inserted into the slot and threads the screw pin into a tooth. When a stop on the screw pin engages the tooth after it has been driven in for a given depth, the engagement projection backs out of the slot discontinuing the driving action.

Abstract: A potentiometer for use with a voltmeter has an impedance transformer (1) to which an unknown voltage (Vi) to be measured is applied, a bank of resistors (2) which act collectively as a variable resistor and having switches (S0, S1, S2, ... Sn-1; S01, S02, ...S(n-1)8) connected in parallel with the respective resistors of the bank, a switch control circuit (4), and a multiplier-setting circuit (5). The transformer, the bank of resistors and the voltmeter are connected in series. The resistors have respective resistance values r, 2r, 4r, 8r, ..., 2<n-1>r or 10<0>(r, 2r, 4r, 8r), 10<1>(r, 2r, 4r, 8r), ..., 10<n-1>(r, 2r, 4r, 8r), where r is a minimum, or unit, resistance value. The value r multiplied by a multipler N of two or more digits is equal to the resistance value of the variable resistor. This multiplier N expressed in decimal notation is set by means of the multiplier-setting circuit, which causes the switch control circuit to selectively open the switches, thereby adjusting the resistance value of the variable resistor bank.

Abstract: An improved child resistant package comprising a container and closure and resilient means for normally urging the closure axially away from the container when the container is sealed by the closure. Cooperating sets of locking elements rim the container adjacent its mouth and are disposed about the inner surface of the depending skirt portion of the container for locking and maintaining the closure in a sealed position over the mouth of the container. One set of the locking elements comprise pairs of spaced apart projections which define a through-running channel therebetween. The other set of locking elements comprise corresponding latch members, each of which defines a stop element which is received in through-running channels and a retaining portion which acts against one of the paired projections to retain the closure from axial movement in opposition to the urging of the resilient member. In the event of the shearing of portions of the projections, the locking feature of the closure is retained by virtue of the through-running channel which permits the latch member to be positioned toward the container mouth with the surface of the stop element in contiguity with undamaged portions of the projections.

Abstract: A method for substantially continuous machining or shaping of sheet pieces from sheet material, wherein only part of the sheet material at a time is under machining. In the method the sheet material is fed in steps longitudinally forwards; on the surface of the sheet, in the direction perpendicular to its travel direction, there have been positioned in parallel typically several workpieces; and the machining is carried out by machining methods appropriate in each particular case and by using corresponding tools. The tool holders designed for the purpose of attaching various machine tools, and situated at least on one side of the sheet, can be moved and guided at least as one entity in a direction perpendicular to the travel direction of the sheet, starting from the first longitudinal edge of the sheet and ending at the other longitudinal edge of the sheet, the machine tools in use carrying out their machining step during this transfer, synchronically in accordance with predetermined sequencing. When the transfer is repeated from the first edge of the sheet to the other edge of the sheet the workpieces have been fitted to adjoin one another without steps in the travel direction of the sheet.
