Title: Sugar extraction from molasses by reaction with quick lime - with direct cooling by addition of ice crystals
Inventor: KUBASIEWICZ ANDRZEJ DR ING
IPC: C13B35/04
Filed: 1976-05-03
Abstract: Sugar is extracted from molasses by diluting the latter, treating it with quick lime, filtering and further processing the resulting saccharate milk. The process is improved by adding to the reactor ice crystals (pref. suspended in water) in such amts. that the optimal temp. is maintained to stabilise the saccharate. The direct cooling with ice is more convenient than the indirect cooling applied in the conventional processes. The appts. is simplified and the operating cost is reduced.

Patent DE-2632083-A1 (DE)
Title: Multifilament thermoplastic yarn crimping - with yarn plug passed into a permeable guide path for processing with small mechanical force
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D02G1/12
Filed: 1976-07-16
Abstract: The crimping unit for processing multi-filament thermoplastic yarns has a holding chamber where the yarn is fed in at high speed to build up a plug, from which the yarn is drawn out at a constant speed. The yarn is built up into a plug by rollers in a pair at the outlet of the holding chamber operating at a speed to hold the shape of the plug and pass it in a straight line into the grooved path of the process tube. The path is permeable and is subjected to a gas stream to press the yarn plug against the guide path with (part) of the gas stream penetrating it. Drawing out rollers extract the yarn from the path of the process tube at a speed which is greater than the intermediate speed and approximately equal to the speed at which the yarn enters the holding chamber. Process gives an effective thermal treatment without requiring side limits in the treatment chamber, allowing it to stretch out freely, and with little mechanical applications.

Filed: 1976-08-13
Abstract: The production of a pharmaceutical composition with delayed release of active ingredient starts from a polymer containing acidic groups. This polymer contains 10 to 100% hydrophilic groups and 0 to 90% hydrophobic groups. The polymer is reacted with a basic pharmaceutically active compound to give a salt which is soluble or dispersible in water or in organic solvents. The hydrophilic groups in the polymer are derived, for example, from acrylic acid, vinylpyrrolidone, methacrylic acid and/or maleic acid, and the hydrophobic groups in the polymer are derived, for example, from methyl methacrylate, butyl methacrylate, lauryl methacrylate, methyl acrylate, 2-ethylhexyl acrylate and/or styrene. The pharmaceutically active compound incorporated in the pharmaceutical composition is, for example, an alkaloid, preferably pilocarpine, in particular cocaine or morphine, a local anaesthetic, preferably dibucaine or lidocaine, an analgesic or a sulphonamide, preferably sulphadimethoxine. The pharmaceutical compositions with delayed release of active ingredient produced in accordance with the above statements can, inter alia, be in the form of solids as inserts in body orifices.

Title: Cleaning optical glass to remove water - using boiling organic detergent and multiple rinsing tanks
Inventor: GOLLMICK HANS-JOACHIM DR
IPC: B01D12/00
Filed: 1976-09-25
Abstract: Water is eliminated from the surface of workpiece, esp. glass parts, by immersing the parts in a boiling bath contg. an organic detergent immiscible with water, plus surfactants. The parts are then rinsed in pure organic liq. to remove the surfactants. Layer of water obtd. in the detergent bath is removed, and the vapour is condensed and returned to bath. Vapour from the bath is condensed separately, the condensate from detergent bath passing through a water separator and being returned only to the same bath, whereas the condensate from baths is fed through a drier and returned only to rinse baths. Pref. three rinsing tanks are used; the first and third being heated electrically whereas the second is fitted with an ultrasonic generator; and separate condensn. coils are fitted above the boiling tank and the rinsing tanks. Efficient removal of all traces of water from optical glass parts is achieved to avoid stains etc., which interfere with the optical properties of the glass.

Title: Air and heat permeable pressure compensation mat - has aromatic polyamide fibre system combined with rubber to form mats
Inventor: SCHREUS THEO
IPC: C07J21/00
Filed: 1976-11-05
Abstract: The mat comprises fibres of aromatic polyamides which consist of ring form aromatic components in contrast to the straight chain polyamides such as perlon and nylon. These fibres have extraordinarily good thermal stability over the range from -200 degrees C to +250 degrees C. No significant distortion takes place in the length and width of the pressure compensating surface within this temp. range. The yarn system can be worked together with other suitable materials such as rubber in multifilament or monofilament form. The compact rubber mat can be used for bonding and for ensuring sufficient heat flow. The air and heat permeable pressure compensation mat is made without using mineral fibres such as asbestos or rubber. The pressure compensation mat ensures sufficient heat transfer and it maintains its properties over long periods under pressure and heat. The yarn system can be used in the form of warp and weft.

The compsn. has a vol. resistivity (VR) of >10 ohm. cm. at ambient temp. and pref. a positive temp. coeff. i.e. when heated should reach a temp. zone in which the VR increases sharply. The electrode layers have a VR of 10, pref. 1 ohm cm and should be capable of extending by about 10-15%, e.g. due to a corrugated and/or ductile structure. The composite sheet should be perforated at slotted in a pattern permitting at least 30%, pref. >100% change in dimensions in at least one direction by distortion of the perforation pattern. In particular, deformation maybe generated by thermal contraction of an oriented material used for the core layer. Used for mfr. of self-heating heat shrink cable terminal or junction sheathing, heat being dissipated by passing a current between the surface electrodes via the core layer. The composite element may be used as a lining for a continuous prefabricated heat shrink sheath, and may be coated with adhesive to bond the shrunk sheathing to the enclosed cable.

Title: Multipass mig butt welding thick plates - using constant height for nozzle through which consumable electrode wire passes
Inventor: EROSCHKIN NIKOLAI ANDREEVITSCH
IPC: B23K9/02
Filed: 1977-03-15
Abstract: The length of the wire projecting downwards from the nozzle is initially longer than the thickness of the plates, and becomes shorter as the number of deposited layers increases. As the length decreases the voltage fed to nozzle the wire speed; and the speed of welding along the gap are all decreased. Productivity is increased without the need to adjust the height of nozzle after each pass; and only a simple butt joint need be used, i.e. V- or X- butt joints are not necessary.

Title: Code marking machine for insulated electric leads - has two spray nozzles producing half rings on leads in antiphase
Inventor: KIMMICH KLAUS DIPL PHYS
IPC: H01B13/34
Filed: 1977-06-07
Abstract: A labelling machine is used to code insulated electrical leads. The leads are fed in the longitudinal direction across a spray nozzle which ejects a vibrating ray of a coloured dye. The waves produced by the dye can be sinusoidal or rectangular and the speed of coding is considerably increased. The coding consists of painting two half rings one after the other around the insulation of the electrical lead. The machine uses two spray nozzles which operate in antiphase such that the colour amplitude of the second coloured dye is zero when the first half ring passes the second nozzle. The coloured dyes are deflected by a deflection electrode system subjected to a high alternating voltage.
