Title: Osteosynthetic pressure plate
IPC: A61B17/80
Filed: 1988-11-17
Granted: 1993-08-25
Abstract: The osteosynthetic pressure plate (1) has a number of holes (2) arranged in the longitudinal axis (5) of the pressure plate (1), these holes being used to receive bone screws. The cross-sectional profile (6) of the pressure plate (1) lying orthogonal to the longitudinal axis (5) is designed in such a way that the sectional planes through the pressure plate (1) parallel to the bone application surface (3) widen as the distance from the bone application surface (3) increases. The underside of the pressure plate (1) intended for bearing on the bone (4) has in addition spherical indentations (10) so that, directly after implantation, cavities are formed between bone and pressure plate (1). By virtue of the optimum adaptation of the pressure plate to the anatomy of the bone as a result of its uniform flexural strength, and because of the spatial conditions promoting vascularisation and bone growth under the pressure plate by means of the minimum bone contact, improved clinical results can be obtained.

Granted: 1993-04-21
Abstract: A collection container for body fluids includes a bag having walls (66,68) adapted to move with relatively stiff and flexible sheet members(76,78). A squeezing force applied to the side edges of the members (76,78) causes them to bend outwardly thereby expanding the bag.

Granted: 1991-10-30
Abstract: Hydraulic engine valve lifter includes a pair of pistons defining a pressure chamber therebetween and a separate lash adjusting piston which defines a lash adjustment chamber with one of the pistons in the pair. One-way valve structures permit fluid to flow from the pressure chamber into the lash adjustment chamber thereby displacing the lash adjusting piston to, in turn, adjust valve lash. Motion damping functions during a downstroke of the lifter pistons are also provided by a valve damper chamber and fluid passageways between the pressure and damper chambers. Structure is provided which opens communication between the pressure and damper chambers during upstroke of the lifter pistons (thereby precluding motion damping) and then closes communication at a predetermined location during downstroke (thereby providing motion damping).

Title: Inductive rotation sensor for a vane-type flow meter
IPC: G01F15/06
Filed: 1989-08-14
Granted: 1993-02-03
Abstract: With this rotation sensor the rotational speed and direction of rotation of a vane-type flow meter can be measured in a virtually non-interacting fashion. Three coils (La, Lb, Lc) are provided for this purpose, which are arranged concentrically around the axis of rotation of the vane and are connected in parallel via a capacitor (10, 11, 12) in each case. The oscillating circuits formed in this way are simultaneously intermittently excited in each case only so strongly that when rotating past a coil a damping element fastened to the vane can increase only the frequency of the voltage of the coil concerned by a small amount. The coil voltages (Ua, Ub, Uc) are supplied to an evaluation circuit (14, 15, 16), by means of which the rotational speed and direction of rotation of the vane are determined from the difference between the frequencies of the damped and undamped coils. <IMAGE>

Abstract: A test/control procedure and material is provided to facilitate standardisation of immunostaining techniques and the assessment of their results. Pellets of an absorbent gel such as agar gel are caused to adsorb individual specific concentrations of an antigen of interest. The adsorbed antigens are confined to the individual pellets as by fixation or by enclosure in a diffusion-inhibiting barrier, and the pellets are installed in individual wells in a block of the gel in a manner to become integrated therein. The block may then be subjected to the same preparative routines as a tissue sample, sectioned and mounted like the sample, and then subjected to immunostaining by the same routine as the sample sections to provide a valid basis for assessment of the stained sample sections by comparison with the stained gel block sections. A gel block of suitable configuration is also disclosed.

Granted: 1996-09-11
Abstract: A digital phase locked loop circuit produces a reference waveform synchronized with a sequence of read data signals by dividing the reference waveform which consists of 0's and 1's windows, into early and late regions for determining the occurrence of a read data pulse within a window. The occurence of a data pulse during an early or a late region produces a corresponding phase error signal. The phase error signal controls the frequency of the reference signal by increasing or decreasing the periods of the early or late regions to synchronize the reference signal with the sequence of read data signals. A period table is addressed by a combination of reference signal timing and a frequency register whose output is modulated over several cycles.

Title: Method and apparatus for bending metal sheet sections
IPC: B21D5/02
Filed: 1989-11-20
Granted: 1993-09-08
Abstract: The method of bending metal sheet sections is carried out with a bending punch and a bending die (27) which has an adjustable base (28). The die holder (26), with an elastic table plate (25) in between, rests on a number of plungers (13, 14), arranged side-by-side, of plunger-cylinder units (12, 13, 14) which can be individually pressure-loaded. Before the bending process, the plunger-cylinder units (12, 13, 14) are loaded with a pressure which is greater than the air-bending force required for the bending. As a result, the said plungers (13, 14) strike a stop (17). After the air bending is complete, the bending force increases and the plungers (13, 14) located in the area of the metal sheet section to be bent are forced back. The metal sheet section is uniformly shaped along the elastic line of the punch edge. Here, the two outermost plunger-cylinder units on the left and right strike stops which compensate for the metal sheet thickness lacking at these locations provided the metal sheet section to be worked is shorter than the length of the die.

Abstract: Dans un convertisseur direct (plus connu sous le nom de convertisseur à sortie polyphasée), on amortit les oscillations harmoniques à plus de deux harmoniques sans pour autant affecter la composante fondamentale en accouplant magnétiquement les sorties multiphasées. On fait en particulier passer les courants de sortie de chacune des sections de convertisseur (UR, US, UT) par un des enroulements (PhR, PhS, PhT) d'une bobine commune. Les sections de convertisseur ne sont du reste accouplées, du côté de leur sortie, que par la charge; des courants transitoires non amortis ne peuvent donc pas circuler entre les sections de convertisseur, ce qui réduit considérablement le besoin de transformateurs du côté entrée des sections de convertisseur.
