Title: Vehicle heating system with fuel fired heater - controls speed of coolant pump w.r.t. rate of rise of temp. of coolant determined by temp. sensor
Inventor: GANZ THOMAS
IPC: B60H1/03
Filed: 1991-07-17
Abstract: The heating system uses the coolant system for the engine and has a fuel fired heater (11) to boost the temperature, especially during engine warm-up periods. To prevent formation of vapour bubbles in the coolant, through rapid temperature rise in the fuel fired heater, the rate of temperature rise is monitored. A processor (18) regulates the speed of the coolant pump (10) to provide sufficient flow to prevent vapour formation. The vapour protection operates up to a set temperature, e.g. 70 deg.C for water coolant system, above which the coolant is effectively degassed. The pump speed is regulated electronically. ADVANTAGE - Simple protection for heater boosters, simple to fit to existing systems.

Filed: 1991-08-16
Abstract: A process and device for the quantifiable evaluation of the physiological impression of reflective surfaces with a point light source of which the light reflected from the measured surface can be detected by a photodetector. From these brightness measurements is formed a series of surface measurements for a number of precisely spaced measuring points, in which the number of prior and subsequent brightness measurements is taken into account. It is thus possible to detect and analyse the wavelengths of the surface irregularities. At least one quality index for assessing the surface concerned is derived from the surface measurements obtained. The device can be designed to be hand-held and moved manually over the surface to be measured. To this end, the device has at least one measuring wheel which is rotated by contact with the surface and the rotary movement of which is used to find the individual measuring points.

Title: Sliver can - has inserted sack to take sliver and sink within the can during filling for consistent coiling
Inventor: HARDER WOLFGANG
IPC: B65H75/16
Filed: 1991-10-19
Abstract: The can to be filled with sliver is fitted with a sack at its opening, with the base of the sack near the top of the can and the end of the sack drawn down round the outside of the can. As the sliver is passed into the sack, its weight causes the base of the sack to sink within the can and the sack end is drawn up the outside of the can. The end of the sack is held by a draw ring against the outer surface of the sliver can. The draw force of the drawing ring can be set by a turnbuckle. The bottom of the sack is reinforced by a laying plate inserted into the sack or integrated into its base. The sack is of reinforced polypropylene. The sack is drawn by the ring from the top, over the can, and also withdrawn from the can as required. When the sliver in the can has been used, at the spinner, the end of the sack can be drawn down the outside for the next filling. ADVANTAGE - The system gives a consistently wound sliver material within the can, especially with cans 800-1000 mm high and a dia. of 250-1000 mm, as the sliver path is not distorted while passing into the can interior as the top layer is always close to the laying appts.

Title: Purifying contaminated water - by adsorption on water wettable crosslinked microporous polymer based on styrene]-di:vinyl] benzene copolymer
Inventor: ASTER DETLEF
IPC: C02F1/32
Filed: 1992-02-12
Abstract: Contaminated ground or drainage water, or water from washing floors or surfaces, is cleaned by adsorption on a water-wettable microporous polymer adsorbent based on a styrene/divinylbenzene copolymer with specific surface above 500 (above 1000) square m/g, prepd. by post-crosslinking of a pre-swollen lightly cross-linked polymer, and with 0.1-5% (0.5-3%) of residual Cl. The water may be pre-treated by sieving and/or filtration, and/or be subjected to a magnetic field to prevent incrustation with lime in the adsorbent appts. The adsorbent is regenerated by heating (in)directly to 70-200 (100-180) deg.C, followed by removal of desorbed matter in air, gas, water or steam as fluid; this treatment may be preceded by displacement of combined matter by an organic solvent, pref. an alcohol ketone or carboxylic acid, or a mixt. of organic solvents, or a mixt. of solvent and water. The displaced or desorbed material is removed from the solvent or fluid, e.g. by evapn., condensation or phase sepn., or is converted or destroyed by biological and/or chemical processes, e.g. oxidn. or hydrolysis, after which the solvent or fluid can be used again, opt. after cleaning. USE/ADVANTAGE - Application is protection of the environment and cleaning of contaminated areas. The contaminants can be isolated in enriched form.

Title: Push=pull power amplifier for impedances with large reactance - uses first stage as control member for voltage-superimposing current source and second stage as control member for emitter follower
Inventor: SCHROEDEL GERHARD
IPC: H03F1/32
Filed: 1992-03-10
Abstract: The amplifier includes two asymmetrical control stages (Ta and Tb) which have different functions. The first stage (Ta) acts as a control member for a current source superimposing a voltage. The second stage (Tb) operates as the control member for an emitter follower, which is controlled from the current demand (IZ) or from a back e.m.f. of the load impedance (ZL). Simultaneously, the voltage-superimposing first stage (Ta), which has priority, is driven by a control amplifier (V). The control amplifier input signal (audio signal) as the required value is compared via a feedback resistor (RF) with the output signal of the power amplifier (UL) so that a voltage proportional to the audio signal is generated on the load impedance. ADVANTAGE - In uncontrolled condition only a very small current flows so that power loss in output stage is reduced to min.

Title: Percusion drum with body forming cylinder - has several bristle-shaped spring or damping members in drum skin edge region.
Inventor: EICHNER KLAUS WERNER PROF DR I
IPC: B21J5/12
Filed: 1992-07-31
Abstract: Boring pressure is simultaneously applied to both ends of a solid blank workpiece (1) so that the forming dies (3) act as counter dies for each other. The bore is extended into the blank only so far, that it remains solid in the section (2), in which the toothing is to be formed. After completion, the dies remain in end position, and continue to apply a defined axial force (F). After completion of the forming, a cutting tool (5) cuts the teeth. Simultaneously, the dual axial force of the forming dies generates a defined stress condition in the solid section, to favour formation of profiles during tooth cutting. This also interrupts tangential material flow in the edge area of the workpiece. USE/ADVANTAGE - Produces light-weight shaft. Gives good profile forming even with high-tensile materials, requires no special tolerances of original blank diameter.
