Patent DE-1811472-A1 (DE)
Title: Chlorination of vinyl chloride or ethylene - polymers in the absence of chlorinated
Inventor: GRESSER DR DIPL-CHEM WILHELM
IPC: C08F8/20
Filed: 1968-11-28
Abstract: Vinyl chloride or ethylene (co)-polymer is chlorinated in aqueous hydrochloric acid suspension at 30-70 degrees C, using short-wave radiation and in the presence of a sulphur dioxide producing substance, e.g. sulphite, bisulphite, dithionite or pref. thionyl or sulphuryl chloride. 0.1-10% by wt. (calculated as available SO2 on the wt. of polymer) of these substances, with additionally 1-20% by wt. dimethylsulphoxide, gives the best results. This method gives an improved product as the imperfect removal of chlorinated hydrocarbon is avoided.

Patent DE-2314956-A1 (DE)
Title: Paper-making slice - for roll former where lower lip is adjustable
Inventor: STEVENS SAMUEL S
IPC: D21F9/04
Filed: 1973-03-26
Abstract: The forming machine has a conventional roller with a fixed upper apron to guide the paper making stock onto the forming surface. The amt. of stock is controlled by a lower lip located between the apron and the roll surface. This can be moved horizontally to adjust the gap between its leading edge and the former, so allowing more or less stock to impinge onto the forming surface. Additionally the stock feed passage may be centrally divided by a hinged paddle with separate stock streams flowing on either side. The slice adjustment causes an appropriate restriction to the respective stock flows to give the desired uniform layer of the different fibre types.

Title: Dowel for fitting in plaster walls - has self cutting thread and pocket for swarf
Inventor: BAPPERT ADOLF
IPC: F16B13/02
Filed: 1974-04-20
Abstract: The dowel is suitable for fitting in walls made from plaster or other slow strength materials. The dowel is provided with an axial hole in which support screws etc. can be mounted.

Title: Device for straw choppers with pivoting knives - has knives fitted around a rubber or plastic support sleeve
Inventor: GROENBERG SVEN DAVID
IPC: A01F29/04
Filed: 1974-07-01
Abstract: The purpose of the invention is to prevent the vibration which takes place when the chopper is started, the knives being in a state of imbalance until the rotor has attained sufficient speed, and the knives are extended radially in relation to the rotor.

Patent DE-2453452-A1 (DE)
Title: Rotor pump for vacuum generation - uses part of cooled outlet medium to cool the rotor
Inventor: KNOBLOCH DIETER DIPL ING
IPC: F04C18/12
Filed: 1974-11-12
Abstract: When the outlet of the rotor pump acts against atmosphere pressure, the heat which is generated in the pump, limits the pressure ratio, as the rotor can expand and jam with the end faces against the housing. To improve the cooling of the rotor, some outlet medium is fed back after passing over cooling coils. The cooling coils are mounted in chambers which are connected to the inside of the pump chamber in such a way that the 'dead' space between cooling chamber and pump housing is as small as possible. The cooling chamber forms an extension of the pump housing and is in the form of an annular chamber round the pump outlet connection. The cooling element is in the form of a coiled pipe which is mounted in this chamber.
