Apparatus and methods for providing personal identifying indicia are disclosed including a protective envelope having a high melting point and substantial corrosion resistance that is dimensioned to fit within a recess formed within a surface of a tooth. Also an identification carrier having identifying indicia placed on it being dimensioned to fit within the protective envelope which is then placed within the protective envelope and bonded within the tooth. The envelope may be constructed from ...

In order to facilitate a simple assembling and disassembling of the individual parts of an instrument for surgical purposes with two working parts displaceable relative to one another and two gripping arms pivotal relative to one another, one of these arms being connected to the one working part and the other to the other working part such that during closing and opening, respectively, of the gripping arms the two working parts are displaced relative to one another, with one of the two gripping ...

A turning-purpose hydraulic circuit characterized in that a discharge passage (20a) of a hydraulic pump (20) is connected to a variable relief valve (21) and a pump port of a directional switching valve (22); a first actuator port and a second actuator port (25, 26) of the said directional switching valve are connected to a turning-purpose hydraulic motor (27); the pilot pressure of a pilot valve (33) is introduced into pressure chambers (31, 32) for controlling a spool in the said directional s...

A multi-purpose keyboard controller includes a matrix keyboard control circuit, a serial keyboard control circuit, a PC/AT port control circuit, and an external interface for RTC control. These control circuits are coupled in parallel with the interface logic of the computer system and use the built-in SMI interrupt mechanism of the computer system for reading and writing the keyboard or capturing keypress events. Software BIOS setup is employed to select one of the keyboard control circuits for...

A toothbrush is disclosed which comprises a rotatably mounted toothbrush head, 100, a connection member, 150, for connection to a linear reciprocal drive means contained in hand-held casing and a flexible member, 160, formed preferably from steel wire or ribbon disposed between the connection member, 150, and the head, 100, and for converting linear reciprocal motion of the connection member to rotational motion of the head.

Methods and apparatus enabling a diagnostic test to be carried out on milk flowing in a milk line from an animal being milked, without interrupting the milking process, in which a portion of the milk is diverted through a by-pass in which an extracting means (14) in the form of a vacuum-operable pump and timer acts to separate from the milk flowing in the by-pass a milk sample and to deliver said sample through an associated sampling valve (16) to a testing device (18).

The invention relates to anvil shears for surgical purposes, particularly for laparoscopic operations. The shears have an anvil (10) and a blade (40) pivotably fitted thereto, which is closed against the anvil by means of an operating rod (30) displaceable in the longitudinal direction of the shears. For improving the cutting action, according to the invention the blade (40) is displaceably mounted on the anvil in its longitudinal direction (41) and is subject to the action of a force forcing th...

A weighting device includes one belt engaged onto a user for exercise purposes and includes a number of pockets formed on the belt for receiving a number of weight members. Another belt has a middle portion secured to the middle portion of the previous belt and is engaged to the previous belt so as to force the weight members toward the users and so as to firmly retain the weight members in the pockets. The weight members may thus be prevented from moving relative to the users.

Device for external connection of the bloodstream of a patient to an external circuit or a fluid source for medical purposes. The device includes a main body with at least a first opening being surrounded by first sealing surface (-s) and being adapted to be protected by a removable protective member. A connecting member with at least one second opening being arranged to be protected by a protective body which is removable with respect to the connecting member. The connecting member is connectab...

Use of a nonwoven overstitched by means of yarns as backing material for medical purposes, characterized in that the ultimate tensile stress strength of the backing material is less than 30 N/cm, in that a compression force of from 0.2 N/cm to 10 N/cm is produced on extension of the back material by from 20% to 70%, and in that the backing material is coated partially or over its full area on at least one side with a self-adhesive composition.
