Title: Mould work and formwork for circular concrete sections - incorporates projecting in-built iron components and uses clamps and sectional components at insert positions
IPC: B28B21/56
Filed: 1989-09-30
Abstract: The formwork and mould appliances are for prodn. of circular precast concrete components e.g. manhole rings, shaft rings, tapered shaft rings. The rings have projecting elements.  These elements include step irons, access ladders and brackets to be cast monolithically with the concrete component.  The formwork apparatus comprises mould core (10) with projecting step irons (11). The mould core (10) has cylindrical mould core walls (13) and upper cover plate (12). A removable mould segment (14) comprises wall section (15) and cover section (16) both of which are shaped similarly to the mould core walls (13). A window shaped opening (18) receives each step iron (11) which locate onto seating (19) each seating (19) is connected to a clamp (20). The outer wall member (21) overlap the wall section (15) to which is welded the clamp assembly (20) with metal rib (24) and the flexible seal (26) vertical alignment, rigidity and cement grout prevention is achieved by tightening clamp (17) whilst horizontal dimensional integrity is accomplished by use of tensioning mechanism (23). After concrete has been placed the clamps are slackened and the complete assembly is ready for reuse. USE/ADVANTAGE - Mfr. of precast concrete annular sections ensures that grout loss is minimised and higher quality finish is achieved.

Title: Liposome(s) contg. fluorescent marker and coupled to antibody - useful as diagnostic reagent and for targetted delivery of therapeutic agent for treating cancer, malaria etc.
Inventor: LANGHALS HEINZ PROF DR
IPC: A61K9/127
Filed: 1989-10-23
Abstract: Liposomes which contain detectable cpds. (I) and are coupled to antibiotics (Ab) are new. More specifically Ab are B8-24.3 and B16-6.2 (target cells: E14 and B16-F10) and are covalently coupled to the lipsomes by: (1) reaction with N-succinimidye-5-acetyl-thioacetate (SATA); (2) treatment with NH2OH to generate free SH then; and (3) reaction with a maleimido-substd. liposome. Alternatively, Ab are attached through a biotin: avidin interaction. Lipsosome components are soybean oil phosphatidyl choline (PC);  cholesterol; maleinimide deriv. and alpha-tocopherol esp. at ratio 1:0.2:0.02:0.01. (I) are fluorescent dyes of the perylene type. esp. N,N'-bis(1-hexylheptyl)-3,4,9 ,10-perylene-bis(carboximide) (Ia). USE/ADVANTAGE - The Ab-contg. liposomes can be targetted to particular sites in the body and provides transport of many (I) (or active ingredient) mol. per Ab mol.. They are useful therapeutically, when loaded with active ingredients (e.g.  cytostatics, virostatics or antibiotics), for treating tumours, virus infections, rheumatic disease, bilharzia, malaria etc., and can also be used to treat CNS diseases, using drugs which will not normally cross the blood-brain barrier. The liposomes can also be used diagnostically in a wide variety of tests, e.g. for AIDS, cancer screening or detection of metabolic disorders. In vivo, the transport and concn.  of the lipsosomes can be monitored fluorimetrically or visually.  (I) provide very high sensitivity without the dangers associated with radioisotopes; remain firmly embedded in the lipid bilayer during transport; are not toxic; have high photo-stability, fluorescene quantum yield and organic solvent solubility, and fluroresce at 540-575 nm, well away from the background.

Title: Redn. of frictional losses in flowing, esp. hot water, systems - by adding specified amts. of salts of nitrilo-tri:acetic acid or EDTA to water to convert turbulent into laminar flow
IPC: C09K3/00
Filed: 1990-06-05
Abstract: Process for reducing friction in flowing media, pref. in warm- and hot-water systems with temps. up to 180 deg. C, involves converting turbulent flow to laminar flow by addn. of chain-like agglomerate-forming salts of nitrilotriacetic acid (NTA) which become oriented in the direction of flow (I), in amts. of 5-20 mg/kg water depending on the rate of flow. More specifically EDTA is used instead of NTA; further amts. of NTA or EDTA are added when making up subsequent water losses from the system. USE/ADVANTAGE - The invention provides a low-cost process for reducing the hydrodynamic frictional losses which constitute a considerable part of the energy losses in pipeline systems, e.g., long-distance systems. The additives (I) are readily soluble in water, chemically stable even at high temp., and inexpensive; only low concns. of (I) are required.

Subsequently, the drum speed is lowered to below 150 U/min and a renewed measuring of the imbalance is undertaken via the speed fluctuations of the drum drive motor. ADVANTAGE - Process yields a measured value that is valid for selecting an appropriate high-speed spinning profile.

Patent DE-4038056-A1 (DE)
Inventor: KERZ LUDO DIPL ING
IPC: H04N1/405
Filed: 1990-11-29
Abstract: The object of the invention is a process for generating and storing digitised density thresholds for defining the grid of a half-tone image. The density thresholds of a section of a grid are stored in a data store as stored words depending on a spot function. In the section, several spots with a number of stored words form a multiple spot and are periodically arranged beside and above one another. A sorted sequence is found for the stored words of the section in accordance with the spot function. Density thresholds are allocated to the stored words depending on the position in the sorted sequence. The actual number of stored words is found individually for each spot in the section. The sorted sequence is generated according to the current spot function. Before position-dependent thresholds are allocated to the stored words, a centre of concentration and final point correction is performed for the spot concerned.
