Patent DE-3924613-A1 (DE)
Title: Feeding sludge at increasing counter-pressure by twin pumps - with transversed feeder including slider controlled to maximise total pump efficiency
Inventor: KNAUER JOACHIM FRIEDRICH
IPC: F04C14/02
Filed: 1989-07-26
Abstract: Reducing amts. of liq., esp. sewage sludge travelling from an inlet (1) to a filter press (4) are measured by a meter (8) in the main flow conduit (8) and communicated to a controller (10). The conduit is split into two parallel connector tubes (11, 12) each including an identical rotary pump (6, 7). A transverse feeder (16) extends from after the first pump (6) to before the second pump (7) and includes a slider (18) kept closed for large flow rates, but opening when the rate drops to about 45% of max. possible value. When the slider is closed, two automatically operating non-return valves (13, 14) open, isolating the transverse feeder from sludge flow. Pressure readings ahead of the press are measured (9) and via controller (9) ensure the slider (18) is opened when one of the rotary pumps is approaching the max. rated pressure. ADVANTAGE - Max. pressure on individual pumps is halved, reducing gap losses and ensuring longer operation in the high efficiency field, where rotor wear and power consumption are reduced.

Title: Safety control for gas fired heater - using temperature sensors in two sites and programmed control circuit
Inventor: BURGDORF ACHIM
IPC: F24H9/20
Filed: 1989-09-18
Abstract: One sensor (14) is mounted directly in the flue and the other (17) behind baffles, to monitor any flow out of the side vents in the flue, e.g. to monitor if the flue is blocked.  The output signals from the sensors are connected to a processor (16) which operates a shut-off valve in a failsafe control to switch  off the burners if the flue is blocked. The sensors are non linear types, with a definite characteristic. They are linked into a potential divider circuit which is monitored by an operational amplifier.  A simple logic system including time delay circuits controls the operation of the shut-off valve. ADVANTAGE - Failsafe control of gas heater.

Title: Successive sections of ceramic exhaust pipe collecting soot - for burning off soot, operates electrically, electrostatically or magnetically to catalytically purify fumes
Inventor: KAINER HARTMUT DR
IPC: F01N3/01
Filed: 1989-11-02
Abstract: Exhaust fumes taken with soot particles e.g. from an IC engine (1) enter the first section (5) of an exhaust line made of ceramics or mixed material which is electrically chargeable or magnetisable, causing the soot particles to adhere. This section (5) of exhaust pipe carries external thermal insulation (3) and leads to an uninsulated second section (7), made in this case of ceramic material to which soot particles attach electrostatically. At least one of the surfaces (5, 7) is made of NOX catalyst and/or oxidn. catalyst.  The first exhaust section (5) is electrically heatable in zones.  Heat insulation between the two sections (5, 7) is by an intermediate sleeve (8) with lower electrical resistance than the first section. ADVANTAGE - Soot collect only in specified areas to a given depth, in an exhaust with low pressure loss. Exhaust cleaning is improved, esp. at idling speeds, with deposited particles burning off.

Patent DE-3937752-A1 (DE)
Title: Automatically starting continuous casting appts.
Inventor: EGOSHI KAZUFUMI
IPC: B22D11/20
Filed: 1989-11-14
Abstract: The equipment consists of a casting mould, a reservoir for molten steel, a device for measuring the level of steel in the mould, and a device for controlling the quantity of steel to be transferred from reservoir to mould as a function of the measured level. This interrupts the flow of steel when it reaches a pre-set level in the mould, where it remains for a given time to stabilise the surface. Withdrawal of the plate formed in the mould then commences, and simultaneously transfer of molten steel from the reservoir is re-commenced so as to keep the level in the mould constant
Patent DE-3943265-A1 (DE)
Title: Prodn. of foamed thermoplastics - by mixing into polymer in or on discharge from extruder specific non-toxic gases which are not harmful to ozone layer
Inventor: KOLOSSOW KLAUS-DAIETER
IPC: C08J9/12
Filed: 1989-12-29
Abstract: Polystyrene and/or polyethylene foam or similar foams are produced by processing the polymer in an extruder and/or during discharge and/or after discharge from the extruder mixing foaming agent with it, using only or essentially N2 and/or CO2 and/or H2O and/or N2O as the foaming agent. The extruder die lips are pref. coated with "Teflon" (RTM). The temp. of the mixed material must be lowered to prevent the occluded cells from bursting, the surface must be densified to prevent loss of the gas used, and the foaming agent must be bonded in to the polymer. The cooling is best conducted in an initial air cooling phase followed by water cooling. The foaming agents can be used as liquids. and pumped in metered proportions into the polymer, but feeding in a measured volume of pressurised gas can also be used. The distribution of the gas is aided by the addition of emulsifier, e.g. glycerol monostearate. ADVANTAGE - The method replaces the foaming agents which are harmful to the ozone layer. The new types of foaming agents are reasonable in cost; they are non-toxic, their functional etc. properties are at least as good as those of former agents, and their disposal is environmentally favourable.
