Title: Microemulsions esp. for diagnosis and therapy of tumours - are protein-free and contain hydrophobic component of cholesterol ester and phospholipid(s) and opt. tri:glyceride(S) and/or free cholesterol
Inventor: MARANHAO RAUL CAVALCANTE
IPC: A61K9/127
Filed: 1993-04-02
Abstract: Microemulsions contg. as the hydrophobic component, a mixt. of a cholesterol ester, phospholipid(s) and opt. triglyceride(s) and/or free cholesterol. USE/ADVANTAGE - The microemulsions can be used as carriers for drugs. They are protein free, but on account of their lipid composition have similarities with 2 DL (low density lipoprotein), but contain no protein component. The microemulsions can bind on the LDL specific receptors which are present in most body tissues. Thus if the microemulsions are injected in plasma mixed with Apo E, they bind on the LDL specific recpetors and are taken up pref. in neoplastic cells which have a greatly increased number of such receptors so that the microemulsions are esp. suitable for delivering active ingredients against cancer. A label, esp. a radioactive label can be worked into the microemulsion which can then be used for diagnoses or for localising malign tumors.

Title: Protection circuit
Inventor: OBSTFELDER INGO
IPC: H02J13/00
Filed: 1993-06-12
Abstract: A protection circuit is used for switching off and temporarily blocking the load section of a machine circuit in the event of an action or the operation of a safety switch (2) by an operator. The circuit has a radio-frequency transformer (T1) which converts the mains voltage (UN) on the primary side into the output voltage (UA) which is required on the secondary side for operation of the machine circuit, and a control loop which acts on the transformation ratio of the radio-frequency transformer (T1) and has a safety switch (2). In order to create a protection circuit in which it is possible to dispense with the use of expensive safety relays, at least one power circuit breaker (3, 4) is connected upstream of the radio-frequency transformer (T1) on the primary side, the drive (5) to said power circuit breaker being supplied via a safety circuit (6) which is DC-isolated from the mains voltage (UN) and the load section (1) and can be activated by operating the safety switch (2). <IMAGE>

Title: Frame for commercial vehicles
Inventor: EMMANN SIEGFRIED DIPL ING
IPC: B62D21/02
Filed: 1993-07-08
Abstract: The invention relates to a frame for vehicles. The object of the invention is to provide a frame which can be manufactured in a simple manner. Furthermore, the intention is for the frame to be adaptable to different constructional designs through the use of the lowest possible number of different components. The longitudinal member of the frame of a vehicle is composed essentially of three different component parts which are each a longitudinal-member segment of the vehicle. The first part of the frame is designed as a front-axle sub-frame which bears the front-axle region and comprises longitudinal-member segments connected to cross-members, and the third part is designed as a rear-axle sub-frame which bears a rear axle and comprises longitudinal-member segments connected to cross-members. The central, second sub-frame assumes the function of the actual longitudinal members and connects the first sub-frame to the third sub-frame. In this arrangement, closed structural parts of the longitudinal-member segments of the central sub-frame may be designed as stores for operating means.
