The aid for implantation of a prosthesis part in a bone comprises a flexible, hollow, fluid-filled cuff for enveloping the bone in the region of the prosthesis part to be inserted and a bandage which can be placed around the cuff and has a tensioning device for applying pressure via the bandage to the bone. It is possible in this way to prevent cracking of the bone on introduction of the prosthesi...

The arrangement for sealing a lubricated ball joint implanted in the human body comprises an annular cuff which is made of an elastic material and which can be fixed to each of the two parts of the joint by means of a tension belt.

The supporting element for holding two adjacent vertebrae in the spine at a distance consists of at least one flexible cushion which can be inserted in place of an intervertebral disc between two vertebrae.

The invention relates to a tablet dispenser for the individual dispensing of tablets, which dispenser is simplified in terms of its construction and improved in the reliability of its functioning compared with conventional tablet dispensers. According to the invention, the tablet dispenser (1) has a separating channel (6) upstream of a delivery opening (3) controlled by a sliding piece (10c) of a ...

In a steam-operated cooking device, towards the end of the cooking phase, steam is conducted via a controllable steam outlet opening (18) out of the cooking space (2) to the suction side of a blower and at the same time air is supplied to the cooking space via a controllable air supply opening (19) from the pressure duct (24) of the blower. In this manner, the steam situated in the cooking space i...

A prosthesis hollow stem which is constructed in the form of a framework of sections and which can be adapted to the flexural strength of the bone for which it is intended is described.

The invention relates to a cementless anchorage mechanism for endoprostheses (3) in bones. Transmission of the forces to be introduced into the bone (4) is effected via a multiplicity of small resilient bending rods or pins (8). Transformation and destruction of bone on the individual bending rods (8) depend on the particular force introduced via a bending rod. This results in a dynamic equilibriu...

An aqueous acidic trivalent chromium and fluoride containing coating (passivating) solution for zinc, zinc alloy and cadmium surfaces contains one or more complex compounds of the formula [Cr(H2O)6-xFx](3-x)+A- wherein x is an integer of from 1 to 3 and A is an anion of the group selected from nitrate, sulfate, phosphate, chloride, bromide, fluoride and iodide. In particular the solution contains ...

In a data processing system, there is included a central processing unit (CPU) and a main memory for storing computer words, the CPU including a cache unit. In operation, the CPU requests that a computer word be fetched, the computer word to be fetched being identified by a real address location corresponding to a location where the predetermined computer word is stored in main memory. The CPU req...

An elbow joint prosthesis comprises a metal humeral component (20) which has flanges (30, 32) forming a recess 34) in which a U-shaped plastic insert (70) is nested. A boss (60) projecting from a metal ulnar component (50) is received within the insert (70) with latero-medial clearance for laxity. A plastic sleeve (82) is received in axle holes (64, 80) in the ulnar boss (60) and the legs (76, 78)...

PURPOSE: To prevent the transmission of an excessive load from a tooling device to a robot mechanism by providing a means for diminishing a load transmitted between its first and second plates instantaneously when these plates have any deformation in their fixed relationship with each other and for connecting both plates again when the fixed relationship is recovered. CONSTITUTION: Any deformation...

Compounds of the formula: wherein the broken line at the 22-23 position represents an optional double bond and wherein either R<1> is H or OH and the double bond is absent, or, the double bond is present and R<1> is absent; R<2> is H, C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, alkoxyalkyl or alkylthioalkyl containing from 1 to 6 carbon atoms in each alkyl or alkoxy group, wherein any of sai...

An electromagnetically actuatable valve, especially an injection valve for fuel injection systems which supply internal combustion engines with fuel, is proposed in which the fuel injection valve encompasses a valve chamber and a core upon which a magnetic coil is mounted by means of a carrier body. Fuel supply openings discharge into a flow passage provided around the magnetic coil. Vapor bubbles...

Dihydrodesoxygriseolic acid, which has the formula (I) and salts and esters thereof may be prepared by cultivating a suitable strain of Streptomyces, e.g. Streptomyces griseoaurantiacus No. 43894, and, if necessary, salifying or esterifying the free acid. These compounds inhibit the activity of various cyclic nucleotide phosphodiesterases, particularly cAMP PDE, and, as a result of this...

In the encoder an audio input signal is firstly given an adaptive pre-emphasis characteristic by a pre-processing circuit (16) and is then converted to a digital signal for transmission by a delta-modulator (22). In order to minimise the digital bit rate the delta-modulator (22) is rendered adaptive by deriving a step-size control signal in a circuit (18) responsive to the slope of the input signa...
