Title: Dental articulator - has ball shaped condylar guide elements with slot in which bolt in condylar column runs and is pressed against guide by screw in groove
Inventor: SCHREIBER HANS DR MED DR MED
IPC: A61C11/02
Filed: 1992-10-22
Abstract: The condylar guide elements (30) to the condylar column (31) are finished as ball segments (32). The centre point (23') of the ball lies on the hinge axis (22). There is a slot (33,34) in which a bolt (35) of the condylar column runs. A fixing screw (37) in a circumferential notch (38) in the bolt, presses the guide element onto the column. A modified hinge axis is programmable to give a defined immediate side shift by a notch and spring loaded bolt acting on a screw.

Patent DE-4307968-A1 (DE)
Inventor: SOMERVILLE THOMAS A
IPC: H02M3/28
Filed: 1993-03-12
Abstract: A low noise battery charger includes a rectifier 3 to convert AC line voltage to an unsmoothed rectified voltage HVDC that is applied to a primary winding 7A of a transformer 7. Another rectifier 10 coupled to a secondary winding 7B applies a charging current to a battery 11. An FET 19 in series with primary winding 7A controls current therein. An incrementing signal SYNC synchronized with the rectified sinusoidal voltage increments a ratchet DAC (50), (Fig 2), until its output voltage exceeds a voltage VSENSE indicative of battery voltage. A low charging rate mode signal ILO is produced when the battery condition voltage VSENSE falls a certain amount below the DAC output voltage. Flow of current through the primary winding 7A is controlled by operating FET 19 at a relatively high frequency and by producing constant turn off times and also by modulating turn on times in response to a signal VISENSE indicative of primary winding current. The battery voltage may be sensed by means of a rectifier 28 and a second secondary 7C on the transformer 7. Alternatively, a - DELTA V detector (5A), (Fig 5) may be connected at the battery side of the transformer 7, the detector providing a signal at a first or a second frequency respectively before and after - DELTA V detection, their signal being passed to the on time modulation (104B), or such capacitor (Cp1), (Cp2), (Fig 9), may be used to pass a signal from the battery side of transformer to - DELTA V detection and on time modulation circuitry (15B) at the primary side of the transformer the signal in this case having a frequency changing linearly with battery voltage. <IMAGE>

Patent DE-4341086-A1 (DE)
Title: Optical Y coupler
Inventor: MEIER JOACHIM
IPC: G02B6/28
Filed: 1993-12-02
Abstract: The non-reciprocal, asymmetric, optical Y coupler is made up of a passing through waveguide (1) with a polymer cladding (3) and a waveguide (2) opening into the side. The main waveguide (1) runs straight at the point where the other waveguide (2) joins. The side waveguide (2) is fed through the cladding (3) of the main waveguide (1) to its core region (4) at an angle which is smaller than the angle for total internal reflection in the main waveguide (1). The ratio of the thickness of the main waveguide (1) to that of the side waveguide (2) is at least 2 to 1. To manufacture the Y coupler, a relatively thin waveguide (2) with a core of quartz or glass is arranged relative to a thicker waveguide (1) with a polymer core (4) such that its free end is at an angle (alpha) to the main waveguide (1) which is smaller than the total internal reflection angle. A high optical energy is coupled into the thinner waveguide (2) which passes into the thicker waveguide (1) and causes the polymer cladding (3) and part of the core (4) to melt. The angle of the thinner waveguide (2) is changed so that its end comes to lie inside the thicker waveguide (1) and the arrangement is then cooled.

Title: Method of surface coating with transfer print colouring
Inventor: HUNKEMOELLER PAUL
IPC: B41M1/30
Filed: 1994-02-16
Abstract: Surface coatings are applied by using a fluidic mass (2), either directly, or via a holding base. The mass is coloured by transfer printing, with the paint, or ink, penetrating into the mass which is transparent. After the paint application a coating of a transparent or translucent surface layer (6) may be deposited. The process uses a heated printing cylinder which can be handled over a floor surface. A heated printing plate may be also used. For small objects it is possible to use a stamp with resilient pad matching the printed face shape.
Patent DE-4405822-A1 (DE)
Title: Current sensor for medical device e.g. electrosurgical trocars and RF ablation device
Inventor: THOMPSON RICHARD K
IPC: A61B18/12
Filed: 1994-02-23
Abstract: A distributed capacitance between a primary current feed conductor (14) and a return path to a source (10) prevents measurement of current at the source end (V) of the conductor. The current sensor includes a reference electrical conductor (22) located beside the primary conductor in parallel but terminating short of it. A magnetic subtraction arrangement (24) deducts the current flowing through the reference conductor from the total load current flowing to the medical implement (12a). The subtraction arrangement has the primary and the reference conductors extending through a transformer in opposite orientations. The current subtraction offsets the effect of the distributed capacitance so as to produce a current measurement corresponding to that delivered to the load of the medical implement. A second transformer (26) is used to determine whether the reference conductor is intact.
