Abstract: Augment element (200) for femoral applications in a knee prosthesis, the augment element (200) comprising a metal body (201) of a substantially truncated conical shape configured to be inserted into a bone extremity and having an outer surface comprising a metal trabecular surface (202). The metal body (201) is hollow with an axial through-cavity (204) defining a plurality of substantially annular transversal sections. The metal body (201) is inclined in a direction of inclination, so as to define at least one eccentricity between a first transversal section (205) at a first end of the axial through-cavity (204) and a second transversal section (206) at a second end of the axial through-cavity (204). The first transversal section (205) is smaller in size with respect to the second transversal section (206). The augment element (200) further comprises a pair of bicondylar supports (220a, 220b) arranged sideways in the metal body (201), each of the bicondylar supports (220a, 220b) protruding from the second transversal section (206) and comprising a tapered body widening away from the metal body (201).

Abstract: This disclosure describes methods, non-transitory computer readable storage media, and systems that provide secure password sharing across a plurality of users and client devices via a shared folder. For example, in one or more embodiments, the disclosed system retrieves a public key set including public encryption keys for client devices having access to the shared folder. The disclosed system provides the public key set to a client device requesting to share the shared folder. The disclosed system receives an encrypted payload for the shared folder and a shared encryption key that is utilized to encrypt the payload and is encrypted in the shared folder utilizing the public key set. The disclosed system also detects key rotation events and notifies one or more client devices to generate a modified shared encryption key and re-encrypt the payload for storage within the shared folder.

Abstract: Die Erfindung bezieht sich auf ein Verfahren zur Mattie­
rung von hochglänzenden Epoxidharzoberflächen, insbeson­
dere bei Leiterplatten. In der neueren Leiterplattentechnolo­
gie werden Leiterplatten mit modifizierten Epoxidharzlacken 
als Lötstoppabdeckung und als Schutzabdeckung beschich­
tet. Diese Beschichtungen sind mechanisch sehr stabil, erge­
ben aber stark glänzende reflektierende Oberflächen. Diese 
lichtreflektierende Oberfläche stört jedoch bei der Beschich­
tung derartiger Leiterplatten. Die Erfindung sieht hierzu ein 
Verfahren vor, bei dem die Leiterplatten über ein Spritzmodul 
geführt werden, das die Leiterplatte beidseitig mit technisch 
reiner Schwefelsäure besprüht. Das erfindungsgemäße Ver­
fahren eigent sich allgemein zur Mattierung hochglänzender 
Epoxidharzoberflächen.
Patent EP-0036194-A3 (EP)
IPC: D04B9/38
Filed: 1981-03-13
Abstract: In a circular knitting machine of the type having two 
needle beds or needle-carrying structures (1,8) for knitting 
plain and purl stitches, the lower needle-carrying structure (1) 
comprises a cylinder and the upper needle-carrying structure 
(8) has a substantially bell-like shape and needle tricks (11) of 
arcuate shape for correspondingly arcuately bent needles 
(13). The arcuately bent needles (13) are controlled by select­
ing jacks (12), in turn controlled by cams (18) arranged around 
the substantially bell-like structure (8). Such a machine can 
have the same number of needles (3,13) on both needle-­
carrying structures (1,8), and accordingly, a higher fineness 
for a given diameter than traditional cylinder and dial 
machines. It also enables knitting loops to be transferred 
between all of the needles (3,13) in the two structures (1,8), 
both from the purl stitch side to the plain and from the plain 
stitch side to the purl, thus enabling the knitting of various 
types of rib pattern, such as 1:1,2:2, etc., without requiring 
any jack replacement.

with the document, and is stopped soon after the docu­
ment has finished. According to the invention, the film 
is stopped - at the end of the document - at the mo­
ment in which the film length used each time for a given 
document corresponds to a whole multiple of a minimum 
standard length.

Abstract: A cathode for oxygen reduction in a fuel cell is formed 
from a host matrix including at least one transition metal 
element which is structurally modified by the incorporation 
of at least one modifier element to enhance its catalytic 
properties. The catalytic body is based on a disordered 
non-equilibrium material designed to have a high density of 
catalytically active sites, resistance to poisoning and long 
operating life. Modifier elements, such as La, Al, K, Cs, Na, Li, 
C, and O structurally modify the local chemical environments 
of a host matrix including one or more transition elements 
such as Mn, Co and Ni to form the catalytic materials of the 
cathode. The catalytic materials can be deposited as a layer 
on the surface of a porous electrode substrate to form a gas 
diffusion cathode or can be formed as a gas diffusion 
electrode.

IPC: F16C17/03
Filed: 1984-06-07
Abstract: A pivoted slider bearing supported on a hydrostatic film. 
The pressurized oil which supports the hydrostatic film is sup­
plied from the wedge film of the bearing. The geometry of the 
pressure transfer passages between the wedge film and the 
hydrostatic film arrange the film pressures so that bending mo­
ments (and hence deformations) on the pivoting pad are mini­
mized. The hydrostatic film is very thin, so the effective bend­
ing stiffness of the pad is the bending stiffness of the hydro­
static film supporting structure. This supporting structure can 
be very stiff. With the hydrostatically supported pivoted pad, 
the high load bearing capacity theoretically available with piv­
oting pads is made available in practice. The hydrostatically 
supported pivoted pad slider bearing is disclosed for applica­
tions in engine connecting rod big-end bearings and engine 
main bearing caps. A geometry which eliminates yaw instabili­
ty is disclosed for applications where load is continuous on the 
pad. A hydrostatically supported pivoted pad slider bearing 
wherein the lubricant is grease rather oil is also disclosed.
