Title: Device for transporting toner in electrophotographic printing devices
IPC: G03G21/10
Filed: 1988-12-22
Granted: 1990-04-26
Abstract: To dissipate (drain) the residual toner from the cleaning station of an electrophotographic printing device a conveying system consisting of flexible silicone tubes (10) is provided in which motor-driven helical springs (17) are arranged. To prevent the toner transport from being disturbed by the drive device (14) of the helical spring (17), the helical spring (17) is driven by a coupling element (16/1, 16/2) which engages on the circumference of the helical spring. A plurality of flexible conveying tubes (10) can be connected to each other, the coupling element (16) then being arranged as connecting element between the flexible conveying tubes (10) and in each case being connected on the circumference to the helical springs (17) driven in the flexible conveying tubes. <IMAGE>

Title: Detonator for underwater projectile - has electrical circuit with acceleration sensor output signal fed to two threshold valve switches via band pass filter
IPC: F42C11/06
Filed: 1990-08-11
Granted: 1991-05-23
Abstract: A surfacing detector and/or target strike detector forms part of the underwater projectile to delay the ignition point accordingly, using a triggered measuring circuit. The trigger device consists of an electronic circuit (ES) whose overload-proof acceleration sensor (P) output signal is first filtered by a band-pass filter (BP) and then fed to two threshold switches (K1, K2) with different threshold values (S1, S2). The threshold switch output signals are routed to the measuring circuit (M). Pref. the acceleration sensor is a piezo-resistive pick-up with greatly reduced seismic mass. The measuring circuit uses a pressure sensor to check the underwater pressure on the projectile prior to firing. An evaluation circuit derives the associated delay for the ignition signal. ADVANTAGE - Eliminates firing error by corrosion-proof igniter set-up.
Patent DE-4039142-C1 (DE)
IPC: B65D90/10
Filed: 1990-12-07
Granted: 1992-06-11
Abstract: So that the residual liquid quantities accumulating in the access shaft cannot reach into the surrounding earth, a collecting trough with one or more apertures for passing through the tank supply lines is inserted into the access shaft. The collecting trough can be mounted on a sealing ring. It is also possible to provide the collecting trough with feet or to mount it on a pedestal. At least two nozzles are embedded in the sealing ring screwed to the access lid with a seal in between, which nozzles are provided with connection threads for connecting the vent line and the suction line. Between the inserted collecting trough and the wall of the access shaft there is a gap or intermediate space which serves to draw off any ingress of rain water without it being possible to mix with fuel residues. <IMAGE>

Title: Operating air heater plant - using boiler heated closed circuit to preheat air and fuel feeds to reducing high value combustion fuels
IPC: F27D17/00
Filed: 1992-06-23
Granted: 1993-09-23
Abstract: A low thermal capacity heat transferring medium is circulated in a closed circuit (13) in order to transfer heat from the off-gases of the air heater plant (1) to the air (8) and combustion fuel (9) feeds via a heat exchangers (16,17,18). Additionally a high thermal capacity heat transferring liquid is circulated in a closed circuit (21) comprising a boiler (25) and heat exchangers (26,27). The off-gas from the boiler is added to the off-gases from the plant (1) before their entry into the heat exchanger (16). Pref. the off-gases finally pass through chimney (12). The heated air and fuel pass to the plant (1) and pass through a combustion shaft (3) and an air heater (2). USE/ADVANTAGE - In air heater plants used to preheat air prior to passing into blast furnaces for the purpose of adding melting. The heating capacity is improved thereby avoiding the need for high value combustion material such as natural gas, coke gas or oil.

Abstract: FIELD: railway engineering. SUBSTANCE: in point sleeper for works the sheet of the formwork bottom serves at the same time as the template for relative positioning of embedded parts. The formwork is normally manufactured anew for each batch of the sleepers of the same type. In case of small production batches with different positions of the embedded parts, multiple use of the formwork bottom sheet is expedient. This is accomplished by the fact that before being mounted in the formwork, the bottom sheet is provided with drilled holes for a few types of precast members. The unnecessary holes are temporarily plugged by a suitable mean, and the combination of drilled holes required for fabricating the certain types of precast members is detected by the certain search method and is freed from temporary plugging.
