Title: Guiding device for electric tools
Inventor: MAIER PETER DIPL ING
IPC: B23Q1/26
Filed: 1987-05-14
Abstract: A guiding device for electric tools such as planes, routers and the like is proposed which has at least one guiding rail (11) and a slide (23) which is guided thereon and holds the electric tool (27) preferably adjustably. At least two guiding grooves (19 to 22) running in the longitudinal direction are arranged on the guiding rail (11) or on the slide (23), and at least two guiding members (24, 25) which engage in the guiding groove are mounted on the respective counterpart. The preferably trapezoidal groove shape allows the slide (23) to be mounted in any longitudinal position. The guiding rail (11) has a flexurally stiff profile with substantial extension in the horizontal and vertical directions. By means of a guiding device of this type, it is possible to achieve increased working accuracy independently of the quality of the support of the guiding rail (11), improved and more precise guidance being achieved by guidance solely in guiding grooves. <IMAGE>

Patent DE-3731318-A1 (DE)
Inventor: DEMPSEY DANIEL JOSEPH
IPC: F23N1/02
Filed: 1987-09-17
Abstract: In a two stage gas furnace system, low and high pressure switches 31, 32 are placed across the heat exchanger and are successively closed, as the inducer motor accelerates during purging, when the pressure drop reaches the respective theoretically desired low and high firing pressure drop levels. (The pressure drop across the heat exchanger is indicative of the level of excess air in the combustion system.) As the switches are closed, the inducer motor speeds are sensed and recorded, with a ratio of the two then being calculated. After firing, the ratio is then directly applied to a desired high firing motor speed to obtain the desired low firing motor speed. The draught inducer blower 23 is driven by the motor in response to control signals from a microprocessor. <IMAGE>

Title: Piston engines with method for improving the reaction in engine combustion chambers and secondary reaction systems
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/02
Filed: 1987-10-13
Abstract: In PCT/DE 85/00152 the formation of a hot zone, which brought important new information, had been achieved by a conversion of the kinetic energy of the pressure wave released from the exhaust gas quantum on the engine exhaust into thermal energy. In P 3700182.5, extension of this effect to new intake-side adjustments to the phenomena was successful in obtaining an <<abrupt emission>>, which maintains the thermodynamic variables pressure, density and temperature in time with the charge cycle for a further distance in the exhaust line. The present application improves this technology by a synchronous system of special construction, which stabilises this energetic speeding up of the exhaust emission process for all operating conditions of the engine and thereby increases the degree of air charging with reaction within the port and valve overlap zone of engines, even in multi-cylinder engines. This results in an exhaust gas of ecologically acceptable quality without reducing the engine power.

Title: Electrical switching apparatus
Inventor: SCHLEDORN GERARD
IPC: H01H23/16
Filed: 1988-05-11
Abstract: Electrical switching apparatuses which are provided for mounting in or on mounting surfaces have manual operating elements for direct or indirect operation of their contact points, which normally carry out a rocker-like movement. Accordingly, the manual operating elements also assume a position which is at an angle to the mounting surface and has a disadvantageous effect on the aesthetic impression. A novel switching apparatus has a manual operating element (10) which is guided in a straight line in the associated switching apparatus base (20) and thus always assumes a position parallel to the mounting surface. At least one sliding rail (16), which is connected at right angles to the manual operating element (10) on its rear side (14), is provided for guiding said manual operating element (10). This sliding rail (16) engages in an associated guide (22) in the switching apparatus base (20). In order to operate the contact point, the switching apparatus base (20) has a switching rocker (30) whose first lever arm is acted on by an actuating cam (17) arranged on the manual operating element (10), and on whose second lever arm a restoring spring (19) acts, which allows use as a monostable push-button switch. The novel switching apparatus is used in domestic installation. <IMAGE>
Patent DE-3817246-A1 (DE)
Inventor: GANZ MICHAEL DIPL ING
IPC: F02B37/00
Filed: 1988-05-20
Abstract: In an internal-combustion engine with two exhaust-gas turbochargers (6, 9), one of these turbochargers can be connected during operation of the internal-combustion engine (1), when a given operating state is reached, on the turbine side by a controlled turbine emergency-valve (12) and on the compressor side by an independent compressor emergency-valve (27). In the charge mode, the turbine emergency-valve (12) acts as a blow-off valve for the turbine (15) of the first turbocharger (6). In the double charge mode, the boost pressure is limited by means of a separate blow-off valve (14) bypassing the turbines of both exhaust-gas turbochargers. Moreover, the charge conduit (26) of the compressor (16) of the exhaust-gas interconnectable turbocharger (9) is connected with the induction side of the compressor (15) of the other exhaust-gas turbocharger (6) by a conduit (28) with a circulating-air valve (29), which is open in the charge mode. The transition from single charge to double charge mode, and vice versa, is determined by the air-mass current (19) taken in. The latter is measured and compared by a control device (31) with a target value, which is corrected according to the speed or the acceleration and according to the angle of the throttle. When the measured air-mass current reaches the corrected target value, the circulating-air valve is closed and the turbine emergency-valve is opened. Since the corrected target value for the air-mass current relates to an operative mode without any significant increase in torque on transition from single charge to double charge mode, the connection occurs without jolts.
