Patent DE-4400202-C1 (DE)
Title: Method for the reduction of hydrocarbon emissions from an internal combustion engine
Inventor: ZAHN WOLFGANG DIPL ING
IPC: F01N3/08
Filed: 1994-01-05
Granted: 1995-04-06
Abstract: The invention relates to a method for the reduction of hydrocarbon emissions from an internal combustion engine during its cold-starting phase, at least one catalytic converter being arranged in an exhaust line of the internal combustion engine and an adsorber being arranged in a bypass line of the exhaust line upstream of the catalytic converter, the said adsorber adsorbing hydrocarbons below a desorption temperature and desorbing them above a desorption temperature. Below a light-off temperature of the catalytic converter and below the desorption temperature, the exhaust gas is, inter alia, passed through the bypass line and the adsorber and, above the desorption temperature, the bypass line is closed. In order to design a method of the generic type in such a way that a significant reduction in the hydrocarbon emissions can be achieved during the entire cold-starting phase of an internal combustion engine, the proposal according to the invention is that a catalytic converter should be arranged close to the engine in the exhaust line upstream of the bypass line, the bypass line being closed when the light-off temperature of the converter near to the engine is reached and kept closed at least until the light-off temperature of the converter arranged downstream of the adsorber is reached.

Title: Electrical tooth-brush with fluid sealing
Inventor: HILFINGER PETER
IPC: A61C17/22
Filed: 1994-03-30
Granted: 1995-08-17
Abstract: An item of electrical equipment, such as a toothbrush, has a main housing (3) with an electrical motor (5) within the base (10). The drive shaft (6) of the motor extends into the stem. The internal region of the base (10) is protected from the ingress of any liquid by a seal (9). This has double lip sealing surfaces that engage the driveshaft. A further lip sealing edge (16) engages the housing. This has a double function of preventing entry of liquid, while allowing pressurised gas build up in the motor housing to be released to the outer region (11).

Title: Injection moulding of components using two different materials and process equipment
Inventor: PRITZKE HEINZ
IPC: B29C45/47
Filed: 1994-09-28
Granted: 1995-12-21
Abstract: A process for injection moulding components using two different materials, esp. plastics involves i) feeding different materials at separate inlets (16,17) in the plasticising unit; ii) plasticising the first material with a large screw (2) inside a barrel (1) and plasticising a second material with a smaller screw (4) rotating coaxially in a bore within the large screw (2); iii) collecting both plasticised materials in a common, variable volume space (7) in front of the screws (2,4); iv) injecting material into a tool cavity via a nozzle (6) by axial movement of the small (4) and/or large screw (2). Claimed process plant comprises a plasticising cylinder (1) with an inlet (16) for the first material and axial and rotational drive units for the large screw (2) and a small plasticising screw (4) for the second material. The small screw (4) includes a non-return valve (9), is rotated in either direction by a motor (10) and moved axially inside the large screw (2) by a drive unit (12). A material inlet (17) for the second material passes through the plasticising cylinder (1) behind the large screw flight (3) and enters an annular groove (18) in the large screw (2). Bores (19) in the large screw (2) feed material from the annular groove (18) to the small screw flight (5). A common chamber (7) in front of the screws (2,4) collects material before injection.

Title: Demodulator for 2-dimensional digitally modulated signals
Inventor: HERBIG PETER
IPC: H04L27/38
Filed: 1994-10-13
Granted: 1996-02-08
Abstract: The demodulator has a zone decision stage which uses decision thresholds for determining lock-out zones in the plane of the 2-dimensional signal values, for providing an acquisition signal when received signal values are within the lock-out zones, for signalling a regulating circuit. The lock-out zones are positioned and sized so that they do not coincide with the circular paths (SS) of the received signal values about the required signal values due to the superimposed sinusoidal interference signals.

Title: Combined fixing and positioning bolt
Inventor: KONING ABRAHAM GIJSBERT DE
IPC: B23Q3/10
Filed: 1996-03-15
Granted: 1997-09-17
Abstract: Fixing and centring is by an expanding bush (2) on one of the components, being secured together by continuous rotary movement. This can produce a high degree of integration within an existing clamping system. A pin (1) is positioned and tightened in a machine bed, while a tapped cone clamps the bush on the top part. The pin is hollow, to allow the passage of air or liquid, and the passage can be shut off by an adjusting screw at the bottom. A nut (3) clamps the pin and bush together, and is locked by a circlip (4). A dirt seal is formed by an adjusting screw (5), a spring (6) and a hexagon plug (7).
