Granted: 1993-06-15
Abstract: The method for requesting a secret number to perform a normal transmitting  if  the  secret  number  matches  a  stored  number, comprises the steps of detecting an OFF-HOOK  state, by  using  an off-hook detector (6), in an initial state of a  phone  mode,  and setting a relay (1) to a facsimile mode if the OFF-HOOK  state  is detected. A secret number is input,  and  then  is  identified  to check whether or not it is exactly the same  as  a  secret  number stored in a memory (9). A normal transmitting  mode  is  performed setting the relay to the phone mode if the two secret numbers  are the same. The controller includes a transformer (2), an  amplifier (3), a MODEM (4), a ring detector (5), an I/O buffer  (7),  and  a CPU (8).

Title: Brewing apparatus for a coffee machine

IPC: A47J31/24
Filed: 1992-07-28
Granted: 1999-09-01
Abstract: A brewing unit has a brewing cylinder (1) with a cylindrical bore (2) and two plungers (3, 4). The brewing cylinder (1) and the plungers (3, 4) are arranged so as to be displaceable relative to one another. In a brewing position, the brewing cylinder (1) and the two plungers (3, 4) located inside the latter form a brewing chamber (5) in order to brew ground coffee located therein by adding pressurised water. The latter is fed to the brewing chamber (5) via a connection nipple (18) and via a through-bore which extends through the wall of the brewing cylinder (1) into a circular gap (14) formed between a sealing ring (11) and the end face (13) of the second plunger (4) facing the brewing chamber (5). The coffee is delivered via a filter (32), a pipe (34) and a further connection nipple (35). Due to the arrangement of the gap (14), the end side (13) of the second plunger (4) can be constructed without a filter. The feeding of pressurised water to the gap (14) causes a self-cleaning effect therein. Due to the construction of the end face (13) of the second plunger (4) without a filter, not only can a part subject to wear be eliminated, but a more cost-effective production of the brewing unit can also be implemented. <IMAGE>

Title: Process for making iron-based sintered pieces with hardened surface layer
Inventor: POPESCU TRAIAN VALERIU
IPC: B22F3/14
Filed: 2005-10-10
Abstract: The invention relates to a process for making iron-based sintered pieces with hardened surface layer. According to the invention, the process provides for sintering a powder mixture consisting of 95% iron, 0.6% phosphorus and for the remainder, up to 100%, other alloy elements (Cu, Ni, Mo and C), homogenized and pressed in a mould, at a temperature of 1120A C, the sinterization being followed by heating at a temperature of 650A C, in a furnace, in an atmosphere of water vapour overheated to 110 - 120A C and at a pressure of 0.6 barr, while maintaining it inside the furnace for 30 min.

Title: Process for obtaining cellulosic fabrics resistant to uv radiations
Inventor: GRIGORIU ANA MARIA
IPC: D06B3/30
Filed: 2007-09-26
Abstract: The invention relates to a process for obtaining cellulosic fabrics resistant to UV radiations, applicable in the field of textile chemical finishing. According to the invention, the process consists of the fact that it is performed in two stages, in the first stage there is performed the graft of the support, which is a flax fabric having the fineness 50/2 tex, cloth binding, and a specific mass of 211 g/m2, with monochlorotriazinyl-beta-cyclodextrin by using a technique of the thermal padding-drying-fastening type, by padding with a solution of monochloro-beta-cyclodextrin 50...150 g/l and sodium carbonate 10...100g/l, pH=11, impregnation time 5...10 min, then squeezing, air-drying, thermal fastening in drying closet for 5...15 min at 90...150A C, removing the reactive excess by repeated warm and cold washing with distilled water, up to a pH of 6.5...7 and drying at the room temperature and in the second stage there are included in the cavity the grafted remainders of triazinyl-beta-CD of some UV absorbers which are obtained by immersing the samples at the room temperature in the solution of an UV absorber 7...12 g/l in a 7/3 ethanol/water mixture, duration of magnetic stirring 1...3 hours, then successive warm and cold washing with distilled water, the hot-extraction of the reactive excess for 5 hours in a 7/3 ethanol/water mixture and final drying at the room temperature.
