Patent DE-4101587-A1 (DE)
Inventor: BAUMANN FRIEDRICH PROF DR
IPC: A61F2/46
Filed: 1991-01-21
Abstract: The invention relates to a stem for a hip joint prosthesis having an elongate stem part (2, 3) implantable in the medullary space of a femoral bone and fixable there by a cement layer. According to the invention, protuberances (17, 18, 19, 21) which have a small area in comparison with the size of the circumferential area are distributed over a few suitable sites on the circumferential area of the stem part (2, 3) as spacers relative to the inner wall of the medullary space. The lower stem part (2) is cylindrical and intended for insertion in a cylindrically drilled medullary space in the socket of the femoral neck. This achieves uniform thickness of the cement layer with only few interruptions for high primary and long-term stability.   <IMAGE>

Title: Internally coated hollow polyacrylonitrile fibres for membrane applications - by treating with cyclohexane, then with alcohol-contg. solns. of PVA and maleic anhydride-ceric salt, and heating to seal larger pores
Inventor: KLEE RUDOLF-JUERGEN DR
IPC: B01D71/42
Filed: 1991-04-25
Abstract: A process is claimed for the prodn. of hollow polyacrylonitrile fibre (I) for membrane applications, using suitable coating materials. The novelty is that the pore on the inside of the capillaries are coated in several stages so as to seal the larger pores in a controlled manner. The coating process involves (a) 10 mins. immersion in a hydrocarbon, pref. cyclohexane, (b) removing the hydrocarbon and treating for 1-3 mins. with a PVA-contg. soln. (A), and (c) removing soln. (A), treating for 1-3 mins, with a soln. (B) which can react with (A) at a sufficiently high temp. and removing (B) before heating to reaction temp., or treating with a mixt. of (A) and (B); solns. (A) and (B) contain at least some monoalcohol, pref. ethanol. Also claimed are hollow polyacrylonitrile (PAN) fibres (I) in which the pores are coated by reaction of polyvinyl alcohol (PVA) with maleic anhydride/Ce (IV) sulphate inside the capillaries, with preferenial coating of the larger pores so as to improve the sepg. power and stabilise the pore structure. Pref. the PAN fibres used are PAN membrane capillaries with 'frozen-in' polymer and pore structure as described in DE4009865. Pref. the coating layer is produced by applying solns. of PVA (A) and Ce(IV) salt/maleic anhydride (B), one after the other or together, and heating to bring about the hardening reaction. The coated capillaries (capillary bundle) are dried evenly by holding them vertically for 1-3 mins. and reversing the fibres several times, and then cured by placing in a horizontal position and heating for 2-4 hrs. at 70-100 deg. C, pref. 3 hrs. at 80 deg. C. Pref. (A) is a soln. of PVA in water-ethanol and (B) consists of maleic anhydride, water, ethanol, polyethylene oxide-diol and Ce(SO4)2.4H2O. Pref., solns. (A) and (B) are applied together as a freshly-prepd. 1:1 mixt., and the solns. contain at least 50 wt.% mono-alcohol, e.g. ethanol. USE/ADVANTAGE - Provides a simple and repoducible process for the prodn. of PAN membrane capillaries with improved separating power, without collapsing the pore structure and polymer structure by using alcohol-contg. coating solns.

Patent DE-4213136-A1 (DE)
Inventor: VETTER HERMANN DIPL ING
IPC: G05F1/46
Filed: 1992-04-21
Abstract: The proposal is for a process for balancing a control device (10) for controlling an electricity consumer (11) fitted with a microcomputer (12) and a device for implementing the process. In it, at least one predetermined value for generating a current flow in the consumer (11) is issued by the microcomputer (12) with the aid of a balancing program. The resultant current flowing in the consumer (11) is issued by the microcomputer (12) with the aid of a balancing program. The resultant current flowing in the consumer is measured and fed back to the microcomputer (12) as a digital value. The measured current (Iist) is compared with a reference value (Isoll) allocated to the predetermined value according to a characteristic contained in the microcomputer. A correction process allocates to the predetermined value a basic characteristic value corresponding to the measured current, the output signal of the microcomputer remaining unchanged. A correspondingly corrected value, an additive correction or a correction function is finally stored. It is thus possible very accurately to set the desired current in the consumer economically purely by software balancing.
