Title: Toilet with flushing water guide pipes - has pipe inserts with flexible flaps automatically moved by water to control flow cross=section
Inventor: GUSTAFSSON JOHN HARRY
IPC: E03D9/16
Filed: 1978-09-18
Abstract: Control flaps form an integral part of a pipe insert ring unit and have a triangular shape with the apex attached to the ring and the broad base facing upstream from the ring. The insert is readily placed in each of e.g. two outlet pipes. The insert is made from flexible plastics material so that the flaps can swivel about their attachment point with the ring. When no water is passing through the pipes, the flaps are axially aligned. They are however, deflected by a water stream whose pressure forces the flaps inwards thereby controlling the through-flow cross-section progressively.

Patent DE-2849083-A1 (DE)
Title: Resonance control switch=off circuit - has comparator to test shift-voltage of two interconnected networks and output signal to control unit if signals match
Inventor: WEBER WALTER
IPC: H02J3/04
Filed: 1978-11-11
Abstract: The circuit is used to switch-off a resonance control unit, for the period that two networks are inter-connected. The resonance control unit holds the shifted voltage, being fed to one network, as an actual input value. A comparator (v) measures the shift-voltage (UEMI, UEML) of both networks (N1, N2). The delayed voltages are tested to see (i) whether they have exceeded a threshold value (S); (ii) if they remain identical over a set period and (iii) if the phase-angle (PHI) has remained the same w.r.t. a common reference value. An 'output' signal is fed to the control unit, if the test conditions (i) (ii) and (iii) are met. The circuit (v) has an AND-gate (4). The phase-angle identical signal is fed to one of the inputs. The other input is connected to a voltage comparator (2) via a clock-stage (3). Threshold stages (1, 2) are connected up to the inputs of the voltage comparator (2).
Patent DE-2849923-A1 (DE)
Title: Vertically adjustable office chair - has gas and compression springs with extra tension spring to increase rate using only light springs
IPC: A47C3/30
Filed: 1978-11-17
Abstract: The height-adjustment mechanism includes a guide tube containing a longitudinally displaceable gas spring (1) braced against the base of the guide tube by a compression spring (21) while a further tension spring (25) is provided which is axially secured opposite the gas spring (1) on one side and the guide tube (2) on the other. The series connection between the compression spring and the tension spring which partially surrounds the gas spring housing ensures that only half the overall force required need be applied by each spring so that the metal springs can be made softer, eg of a thinner spring wire and thus the space required can be reduced for a neater construction.
Patent DE-2852546-A1 (DE)
Title: Purification of sewage with regulation of nitrite - by control circuit responding to concentration and cutting off oxygen
IPC: C02F3/12
Filed: 1978-12-05
Abstract: The dentifrication of the sewage in the activating tank of a purificn. plant takes place during a variable period of time, whilst the feed of atmos. oxygen is cut off. After the supply of air has been interrupted, the falling off of the oxygen content is measured, and the feed is only reconnected, when, after the bottom limit for the oxygen content has been reached, a predetermined period of time has elapsed. The bottom limit is approx. 0.5mg O2/l. The interval of time elapsing between the periods when the oxygen supply is cut off, is selected dependently upon the delivery of raw sewage into the plant. Provide a process which gives full control over the denitrification process, so that the activated sludge is not killed off. There is no denitrification tank as such, so that the layout is simplified.

Title: Selective protection device for current limiting circuit breaker - has lever mechanism engaging and disengaging armature to open switch lock and to actuate contact lever
Inventor: GREEFE KLAUS DIPL ING
IPC: H01H71/10
Filed: 1978-12-18
Abstract: The protection device has an armature actuated by an electromagnetic coil to bring a contact in open position, directly or via a switch lock. The armature is subjected to a permanent magnet attractive force, opposing the tripping direction. A lever arrangement moves between two positions. In the first position it is disengaged from the armature, whilst in the second position it is operated by the armature on breaker tripping, such that it interacts with the switch lock and/or with a contact lever to cause its opening. The lever arrangement consists of a U-section, L-shaped lever and a rod pivoted to it, and shorter than the short shank of the L-shaped lever. Between the latter and the rod is mounted the electromagnetic assembly.

Both the linking piece and silencer casings are flange-joined pressed sheets.
Patent DE-2911179-A1 (DE)
Title: Continuous dyeing of textiles - includes steaming process between padding and drying to activate migration inhibitors
IPC: D06B19/00
Filed: 1979-03-22
Abstract: In high-speed continuous dyeing processes for textile fabrics, after the application of dye-liquor to the fabric it is passed through an atmos. of satd. steam at 100 degrees C for a few seconds before the drying process begins in order to fully activate the heat-sensitive auxiliaries which increase the viscosity of the liquor to inhibit migration. Fabrics containing natural fibres may first be held at room temperature for a few seconds to allow liquor dispersion within the fibres. Equipment to carry out the process comprises a steam-tight chamber through which the fabric passes in zig-zag fashion around a series of rollers before proceeding to the drying section of the plant. The process ensures that the migration-inhibiting auxiliaries are fully effective before drying begins, and that the surface of the fabric is heated to 100 degrees C as quickly as possible. This minimises any unlevelness due to dye migration during the drying stage.
Patent DE-2912282-A1 (DE)
Title: Narrow gauge cine film projector - alters film speed in accordance with different perforation characteristics
Inventor: MUELLER HERMANN
IPC: G03B21/50
Filed: 1979-03-28
Abstract: The projector is for narrow gauge perforated film, having a transporter grip engaging with the perforations so as to index it forward for a picture length at a time. A control disc with notches or cams determines the indexing frequency and can thus slow down the film travel speed, being driven by a tooth on the grip mechanism. The film travel speed is automatically altered in accordance with different film perforation characteristics. The movement of a feeler detecting the perforations is transmitted to the control disc, so as to vary the manner in which it is engaged by the indexing tooth on the grip mechanism.

Patent DE-2917356-A1 (DE)
Title: Location method for reinforcing elements in concrete - uses external heating of concrete and IR recording of reflected heat radiation
IPC: G01V9/00
Filed: 1979-04-28
Abstract: The determination method for different thermal conductivity regions in combined and compound substances, such as reinforced concrete etc. is important for constructional, technological and load calculating considerations. This is of particular importance in concrete structures using bundled of anchoring elements. For this purpose the reinforcement and anchoring elements must be precisely located in the set concrete. The hardened concrete with the reinforcing elements etc. is heated by an external source to an extent at which is reflects a certain thermal radiation. The different radiation in the infra-red range is detected by a suitable film or photographic plate, and the recording can be then used for all necessary calculations. This process replaces with advantage earlier ultra-sonic location and detection techniques.

Title: Fluidised sinter powder encapsulation for capacitors - applying coating to welded anode junction and all over after preheating
Inventor: PETRICK PAUL DR
IPC: H01G13/00
Filed: 1979-05-21
Abstract: A capacitor esp. an electrolytic capacitor with a sintered or wound anode of valve metal (aluminium or tantalum) is encapsulated by applying a fluidised sinter powder. After preheating, a powder transport wheel first applies a coating to the welded junction between a valve metal wire in contact with the anode and an external connecting wire. After another preheating a coating is applied all over. These cycles are repeated until the desired thickness has been achieved. This solves the difficult problem of encapsulating the welded junction.
