Title: Preparation and purification of di- and tetra-chloro - diane
Inventor: GUENTER ZOCHE DR
IPC: C08G63/682
Filed: 1968-10-30
Abstract: (tetrachlorodiane, TCD) and 2,2-bis-(4-hydroxy-3-chlorophenyl 1-propane (dichlorodiane:DCD) prepared by known methods in the presence of solvents inert to chlorine are each purified by dissolving them in a hydrocarbon liquid at 20 degrees C in which they are highly soluble in the absence of water but sparingly soluble in the presence of water and then precipitating them from the hydrocarbon by the addition of an aqueous phase. Suitable hydrocarbons are chlorinated aliphatic or aromatic hydrocarbons e.g. 1,2-dichloroethane, methylene chloride, methyl iodide and 1,1,2,2-tetrachloroethane. Preferably the same solvent is used both for the chlorination reaction and for the purification. The chlorination reaction product need not be isolated before purification. The highly pure TCD or DCD is thus suitable for condensation with bifunctional acid chlorides to yield polyesters eg with terephthaloyl chloride and isophthaloyl chloride.

Title: Ejecting mouldings on cores - then removing them from cores by blowing
Inventor: HERBST RICHARD
IPC: B29C45/42
Filed: 1971-09-15
Abstract: A method of removing injection moulded articles formed around a core within a two-part mould makes use of an area of the core, facing towards the mould, which is free from the moulding; the sequence of operations is as follows: first the two parts of the mould are moved part, next a nozzle manifold comprising blowing nozzles associated with each core is introduced laterally into the mould gap, so that the end of the nozzle is opposite but slightly spaced away from the free face of the core; next, the core is pushed out from the movable half-mould, conveying the moulding with it, until the free surface of the core comes up against the end of the nozzle; air is then blown through the nozzles, stretching the mouldings and lifting them off their cores and causing them to stick to the nozzle ends. The nozzle manifold complete with nozzles and the mouldings on them is removed, so that the mouldings fall off, leaving the mould free for the next cycle.

Title: Early diagnosis of mucoviscidosis - by colour reaction between albumin in the meconium and a plastics-supported dye-impregnated test paper
Inventor: BUSCH ERNST-WERNER DR MED
IPC: G01N33/68
Filed: 1973-03-20
Abstract: Device for diagnosing pathologically elevated albumin content of the meconium comprises a 4-10, esp. 5-6 mm. wide and 20-40 esp. 30, mm long albumin test strip which is mounted onto a plastics strip of the same width and 20-80, esp. 30-50, mm long. Pref. papers which give a deep blue colour are used (e.g. tetrabromophenolphthalein ethyl ester and N-contg. anionic wetting agents). In use a portion of meconium is placed on the lower end of the strip which is then placed in a tube contg. water, and as the water moves upwards it dissolves the albumin from the meconium giving a colour change in the sensitive part of the paper. High albumin content may be indicative of cystic fibrosis a cogenital disorder of new-born babies which must be diagnosed as early as possible. The present method is quick and accurate and suitable for routine use as part of a screening programme.
