Title: Telephone set accepting coded key - whose coding initiates frequencies for comparing with incoming tariff-signal frequency to decide users authorisation to call given area
Inventor: KUCHLER FRITZ DIPL KFM
IPC: H04M3/38
Filed: 1978-03-25
Abstract: The telephone set accepts plug-in coded keys authorising certain users to call certain areas as described by the code on the key. The signals initiated by the keys when inserted into the set are a.c. signals whose frequency is determined by the key coding. These frequencies are compared with the call-tariff signals coming from the exchange. If the clock frequency of these tariff signals exceeds the frequency of the signal initiated by an inserted key, a switch is operated that disconnects the connection. The incoming tariff signals are passed to a store and display located in the key.

Title: Oxidation of organic sulphide(s) to corresponding sulphone(s) - using hydrogen peroxide, a carboxylic acid and a mineral or sulphonic acid catalyst
Inventor: CHAN JOHN KAI-FAI
IPC: A01N47/24
Filed: 1978-04-04
Abstract: An organic sulphide is oxidised to the corresponding sulphone with a mixture of H2O2 and a carboxylic acid in the presence, as a catalyst, of a mineral acid or an organic sulphonic acid. The process gives higher yields of sulphone (e.g. 66-90%) than are obtd. in the known process performed in the absence of acid catalyst (e.g. 34%) with less formation of sulphoxide by-product (generally is approx. 0.1% if a sufficient quantity of acid catalyst is used as opposed to e.g. 15% in the absence of a catalyst). The sulphone products have a wide vareity of uses e.g. as insecticides, miticides and nematocides. In a typical example, 2-methyl-2-methylthio-propionaldehyde O-(methylcarbomoyl)-oxime is oxidised to the corresp. sulphone using H2O2 and formic acid in CH2Cl2 contg. concd. H2SO4.

Title: Cleaning system for building exteriors - uses deionised or pure water preventing extra deposits from settling on walls
Inventor: HELMDACH GUENTER
IPC: E04G23/00
Filed: 1978-04-08
Abstract: Building structures and components are cleaned by chemically pure or deionised water and/or the water vapour produced therefrom. First the steam is applied followed by a water rinse. Solvents for removing the built-up deposits can be added to the water and/or steam whilst means to speed up the drying process can also be used. By using the pure water a better cleaning action is achieved without any of the impurities contained in tap water being deposited back on the walls. NOsould be cleaned from bottom upwards since otherwise the water flowing off at the top clogs up the lower pores which are still to be cleaned with steam.
