Title: Oil fired boiler afterburner - has baffles filtering out combustible particles for combustion to improve heat output
Inventor: BOEHMER WALTER
IPC: F23M9/06
Filed: 1976-03-22
Abstract: The provision of baffles in the path of flames in an oil burner ensures filtering out of unburned particles in the flame, and this leads to their burning by the incandescent baffles. The flame from tube (3) in the boiler (1) strikes the ring-type baffle (5) at a high velocity and raises the temp. of the baffle till it is red hot. The oil particles are ignited on the edge of the flame whose core is turbulized by air oxygen before impinging baffles (6) which have perforations. The flame is then split into partial jets striking the solid angled baffle (7) which divides the flame into two parts. Change of flow direction contributes to ignition of the remaining particles so that the combustion gases reach the flue without pollutants.

Title: Plaster-drying accelerator - contg. aq. soln. of polyglycol ether, benzyltrialkylammonium chloride and opt. metal soap and/or fatty acid
Inventor: DOLIWA ALBERT
IPC: C04B24/08
Filed: 1976-03-27
Abstract: Additive for plaster accelerating the drying of masonry contains (in wt.%) a polyglycol ether 20-60 (pref. 50-60) and a benzyltrialkylammonium chloride 0.01-5.0 (pref. 2-3), the balance is water. The additive may opt. contain 0.01-3.0 wt.% (pref. 1.0 wt.%) of a soap(s) of Hg, Cu, Ca, Zn, Zr, Co, Mn, Ni, V and/or Sn. It may also contain 0.1-5.0 wt.% of a satd. or unsatd. 5-18C fatty acid, pref. coconut fatty acid. This additive very effectively reduces the surface tension of the plaster compsn. so that the evaporation is greatly accelerated both from the plaster and from the brickwork substrate or the like, (even an old stonework). Metal soaps enhance the surface tension-lowering effect and also exert bactericidal and fungicidal action. The fatty acids act as preservatives, improve the flowability of the compsn., and the adhesion of the plaster to the substrate. They also suppress the salt efflorescence.

Title: Rotary or sliding variable resistor - has slider of same length as resistive element making acute angle with element so that small movements give large resistance changes
Inventor: SKOPIL ARTHUR
IPC: H01C10/30
Filed: 1976-04-28
Abstract: The variable resistor comprises a carrier having an electrical resistance and a slider movable along a taping path across the resistor. To enable large changes in resistance to be achieved without the need for large rotational or displacement paths to be travelled by the slider, the slider has an effective length matching approx. the length of the tapping path. The longitudinal axis of the slider subtends an acute angle with the tapping path on the resistor, at least on part of its length. A small change in angle between the slider and resistor rapidly changes the number of turns covered, and consequently the resistance of the device.
