Patent DE-3816614-A1 (DE)
Title: Method and device for coating printed circuit board assemblies
Inventor: BEHRINGER GEORG
IPC: H05K3/00
Filed: 1988-05-16
Abstract: It is intended to apply a liquid coating material, as a protective layer, onto the solder side of the assembly on printed circuit boards which are fitted with components. According to the invention, the coating material is applied via rollers, from underneath, onto the printed circuit boards as they pass through in a guide path, the plug connections and front sides of the printed circuit boards, which are not to be coated, running in lateral rails of the guide path. In the case of the associated device having a supply container (20) and conveyor and coating rollers (21 to 24), by means of which the coating material is applied from underneath onto the printed circuit board which is running in the guide path, the guide path (10) is broader than the coating rollers (23, 24) and has lateral rails (12, 13) in which printed circuit boards run, including the connecting plug and/or front sides which are not to be coated. <IMAGE>

Title: Fuel feed device for internal combustion engines
Inventor: NUSSER HERMANN
IPC: F02M37/10
Filed: 1988-07-01
Abstract: In a fuel feed device for internal combustion engines with a fuel tank (10) and a fuel pump (12) arranged therein, the fuel pump (12) is elastically supported in a housing (13) fixed in the fuel tank (10), leaving a gap (20) between housing inner wall and fuel pump (12), in order to prevent the transmission of structure-borne noise to the fuel tank (10).

Title: Fuel feed for a regeneration burner of a diesel particle filter
Inventor: HOUBEN HANS
IPC: F01N9/00
Filed: 1988-10-13
Abstract: In known regeneration burners the fuel flow which is fed to the regeneration burner is controlled only between two extreme settings, that is release of the fuel feed and shut-off of the fuel feed. An adjustment to different operating conditions of the internal combustion engine is thereby not possible. In the present invention a plurality of possibilities are set forth for purposeful control of the fuel flow (4) to be fed to the regeneration burner. A common feature of all solutions proposed is that a control module (1) emits an output signal, which represents a measure of the fuel quantity to be fed to the regeneration burner. The said output signal then controls the fuel flow (4) by way of suitable auxiliary devices. <IMAGE>

Title: Semiconductor switch
Inventor: SCHULZE HANS-JOACHIM DR
IPC: H01L31/111
Filed: 1988-11-07
Abstract: Semiconductor switch having a main thyristor and a separate auxiliary thyristor (1, 2) which can be fired by light pulses and in which the n-type base layer (11) of the auxiliary thyristor (2) is considerably less strongly doped and has a substantially greater layer thickness than the n-type base layer (5) of the main thyristor (1), and in which the p-type base layer (10) of the auxiliary thyristor (2) is less strongly doped than the p-type base layer (4) of the main thyristor (1) in the corresponding boundary zone. As a result, the firing sensitivity is increased, without the dU/dt behaviour of the auxiliary thyristor (2) deteriorating. Instead of enlarging the layer thickness of the n-type base layer it is also worth considering incorporating an n<+>-type stop zone. <IMAGE>

Patent DE-3907754-A1 (DE)
Title: Time-controlled water feed in domestic dishwashers
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: A47L15/46
Filed: 1989-03-10
Abstract: In order that a correct operating sequence is ensured in domestic appliances which carry water, their feed must be monitored. Appliances without such devices can be heated dry in an irregular manner. In the case of the solution according to the invention, the water feed is controlled in terms of flow and time. When the water cock is closed, the operating programme does not run. A magnetic float (R) located in the input of the feed vessel closes a magnetic switching-on contact (b62) when water is flowing in. Said contact applies voltage to a timer motor (m3). After a predetermined time has elapsed, the switching-off contact (3b3) opens (m3), the solenoid valve (MV) closes and a precisely measured quantity of water is present in the appliance tank as a result of the constant feed rate. If no water flows, (R) cannot operate its (b62). If the heater (r) becomes dry, (f10) interrupts the heating circuit and applies the voltage to (m3) which, for its part, additionally and permanently disconnects the heater (r) via (1b3). In addition to use in domestic dishwashers, use in an equivalent manner for domestic washing machines is possible. <IMAGE>

Title: Injection moulding miniature ceramic parts - obtd. from powder mixed with paraffin-polymeric binder mixt.
Inventor: GUETHER HANS-MICHAEL DIPL ING
IPC: C04B35/111
Filed: 1989-08-05
Abstract: Thin-walled miniature ceramic parts are made by a low pressure hot injection moulding process involving blending the non-plastic ceramic powder with a paraffin-binder mixt.  in which the paraffin is partially replaced by a wax or ester, the binder mixt. being driven off by heat treatment after injection moulding. The novelty is that (a) the ceramic powder is a finely dispersed powder with a specific surface of over 80 sq.m./g. and with particles having a fine internal structure with extremely wide voids of up to molecular dimensions; (b) the powder is mixed with at least 85 wt.% of a paraffin-binder mixt. in which 19-70% of the paraffin is replaced by low molecular polymers having mol. wts. of about 2000 g/mol and numerous polar gps.; and (c) the injection moulded part is heat treated at up to 250 deg.C for 6-72 hrs/dohrs. on substrate with 45-50% open porosity. USE-ADVANTAGE - The process is used in the mfr. of miniature ceramic parts, e.g. needle guides for needle printers, with less than 0.1 mm wall thickness. Miniature parts of complicated geometry can be made with extremely high precision since total shrinkage of the sintered parts is reproducible and within narrow tolerances. Sedimentation and de-mixing of the starting mixt. is avoided and the parts have high shape stability after binder removal.

Title: Vacuum packaging of fruit for storage - conditions during packaging stage are chosen such that vacuum is created in package through fruit respiration during storage
IPC: B65D81/20
Filed: 1989-08-26
Abstract: A process for packaging and storage of fruit and vegetables under a sealed cover e.g. polyethylene film is described. The packaging acts as a vacuum package both during storage and for selling to purchasers. Vacuum is created by the natural respiration of the fruit within the sealed package. The dry air necessary for the continuous ripening process is calculated so that after a given storage time and a specified temp. during packaging a vacuum occurs as the temp. is lowered. The ratio of CO2 gas given off to O2 gas taken in by the contents of the package is less than one.

Title: Breaking down of volatile organic pollutant(s) - by combined action of photo-synthetically active algae sharing reactor cavity with pollutant selective bacteria
Inventor: MAERKL HERBERT PROF DR ING
IPC: C02F3/10
Filed: 1990-03-09
Abstract: In the biological breakdown of volatile organic materials, photo-synthetically active algae absorb inorganic carbon in the form of CO2 while emitting O2. The O2 is taken up by a separate colony of bacteria which in turn produce CO2 needed tby the algae. On a suitable reactor, light received through a transparent outer cylindrical casing impinges on algae in the outer compartment sepd. by a gas-permeable membrane from an inner compartment. The membrane surface facing the outer casing supports the algae which emit O2, transferring by a pressure gradient to the inner compartment where the membrane is coated with bacteria suitable for the particular gaseous pollutant. Gases are exchanged between the two compartments via a filter. A reactor may hold a suspension of algae, with light-sources arranged in an internal pattern, or a single elongated light tube. USE/ADVANTAGE - For by-prods. from petroleum processing etc. which include harmful material such as carcinogens. With effective use of light in combined operation by algae and bacteria, breakdown efficiency is improved.
