Patent DE-4023920-A1 (DE)
Title: Throughflow heater for tea or coffee making machine - has two temp. regulating switches in series, with high and low opening temperatures respectively
Inventor: WONKA BORIS
IPC: A47J31/54
Filed: 1990-07-27
Abstract: Cold water flows from a supply container to the throughflow heater for heating by an electrical element and supply to a brewing unit. The latter supplies a receiving container situated on a hot retainer plate also heated by the throughflow heater (4). The prepared drink is kept hot by the temp. regulated retainer plate. A first regulating switch (7) is in the form of an electrical switch open above its opening temp. A saecond regulating switch (8) is placed in series with the first. The latter (7) is thermically coupled to the heater (4) at the side of the inlet opening (16) and has a relatively low opening temp. The other (8) is coupled to the heater at the side of the outlet opening (17) and has a higher opening temp. ADVANTAGE - Protects against overheating in keeping hot mode. Avoids unnecessary interruption of current supply during brewing and average heating periods.

Title: Removing water from alcohol(s) or fuel compsn. contg. alcohol(s) - by mixing with acetophenone di:alkyl ketal or acetophenone enol alkyl ether and passing through acid and basic ion exchange resins
Inventor: KISAN WERNER DR
IPC: C07C29/76
Filed: 1991-06-03
Abstract: Water is removed from alcohols or from fuel compsns. contg. alcohols, by continuously passing the alcohol or fuel mixt., with addn. of an acetophenone dialkyl ketal (I) and/or an acetophenone enol alkyl ether (II), in the liq. state, at normal pressure and ambient temp., over a fixed catalyst bed comprising an acid ion-exchange resin and/or an acid zeolite and a later, lower layer of a basic ion-exchange resin. Pref. the aq. alcohol is (m)ethanol or mixts. of 1-80 alkanols. The fuel is a Otto fuel contg. hydrocarbons in the gasoline range and 1-8C alcohol(s). (I) is acetophenone di(m)ethyl ketal, and (II) is an alpha-(m)ethoxystyrene. The acid ion-exchanger is a cross-linked styrene/divinylbenzene copolymer sulphonic acid in the H form, and the zeolite is a high-Si zeolite of the ZSM-5 type, a decationised zeolite of the Y type, or a zeolite of the X or Y type, modified with polyvalent cations by ion-exchange. The lower, basic ion-exchanger is of the type of a styrene/divinylbenzene copolymer with tert. amino gps. USE/ADVANTAGE - The process is esp. removal of the last water in the distillative sepn. of alcohol mixts., and the dehydration of alcoholic fuel mixts. The process is economical in energy and appts., is cheap, avoids costly additives, and avoids removal of by-prods. forming azeotropes with the alcohols. (I) and (II) and the acetophenone formed are solubilisers in alcohol/gas line fuels, and raise the octane number in Otto engines. The acid catalyst requires no regeneration.

Patent DE-4132369-A1 (DE)
Inventor: SCHWARZ WERNER RICHARD DIPL IN
IPC: B65C9/46
Filed: 1991-09-28
Abstract: The device (10) for the printing and dispensing of labels (16) sticking on a strip-shaped liner (14) of carrier material is provided with a printing means (46) which, in advancing direction of the liner, is arranged at a distance before a separation means (54) for separating an already printed label from the liner. For providing the liner with labels over the largest possible area on the liner surface, the labels are arranged on the liner relatively closely adjacent to each other. To make it possible that, after dispensing of one label, printing on the following label can start at the leading edge thereof, the liner is moved backwards after dispensing of one label until the front edge of the next label is positioned before or level with the printing means. This control sequence allows processing of liners in which the distance between adjacent labels is smaller than the distance between the printing means and the separation means. If the labels are arranged directly abutting each other, the position of the labels is detected by temporarily bending the liner within part of the transport path (34, 36). Thus, the gap between adjacent labels will widen and accordingly be detected by a light beam (40, 42).
