Title: Temperature compensator bridge circuit
Inventor: PRESSNER PETER
IPC: G05D23/24
Filed: 1969-07-08
Abstract: 1298203 Automatic control of temperature SATCHWELL CONTROLS Ltd 2 July 1970 [8 July 1969] 34424/69 Heading G3R An automatic temperature control system for a hot-water central heating installation comprises a bridge circuit as shown including a water temperature sensor D1 and an outside ambient temperature sensor D2. D1 and D2 are both NTC thermistors, Dl having a linearizing resistor in parallel therewith. At 20‹C., the resistances of D1 and D2 are equal also after initial balancing by adjustment of P2 the resistance of D2 and part of P2 equals R1+ the other part of P2. The bridge will be balanced when the outside temperature and water temperature are both 20‹ C. independently of the setting of a potentiometer P1. In operation, if the outside temperature decreases D2 will increase and the resulting bridge unbalance amplified at 5 operates a control means to increase the heating water temperature. As the water temperature increases, the resistance of D1 decreases until a new balance point is reached and the water temperature remains steady to provide heating of the building sufficient to compensate for the drop in outside temperature. By means of P1 the ratio of the effects of D1 and D2 on the bridge can be varied to selectively adjust the relationship between the temperature of the outside air and that of the heating water. Alternatively potentiometer P2 may be omitted and a potentiometer connected between R3 and R4.

Title: Process for the preparation of aromatic oxyaldehydes
IPC: C07C45/28
Filed: 1927-12-20
Abstract: 285,451. Riedel Akt.-Ges., J. D. Feb. 17, 1927, [Convention date]. Aromatic oxyaldehydes are obtained by oxidizing, propenyloxybenzenes with an excess of nitrobenzene in the presence of excess of alkali hydroxide. The reaction may be rendered less violent by adding a larger excess of nitrobenzene. Thus, iso-eugenol yields vanillin, 1-oxy-2-ethoxy-4-propenylbenzene yields the next higher homologue of vanillin, and isochavibetol gives isovanillin Derivatives of 1 : 2-dioxy-4-propenylbenzene, e.g. the 2-methoxymethylether of 1 : 2-dioy 4-propenylbenzene, yield the corresponding aldehydes. In an example a vacuum dried mixture of isoeugenol and potash solution is covered with nitrobenzene and heated, the sodium salt of vanillin being obtained after removal of excess nitrobenzene and the aniline formed. The Specification, as open to inspection under Sect. 91 (3) (a) also states that aniline might be added as well as nitrobenzene to render the reaction less violent. This subject-matter does not appear in the Specification as accepted.

Abstract: 983,890. Furnace grates. VON ROLL A.G. Sept. 11, 1962 [Sept. 11, 1961; Jan. 23, 1962], No. 34757/62. Heading F4B. In an inclined grate for an incinerator, raking elements used for loosening and shifting the combustible material, e.g. refuse being burnt, are movably mounted on grate bars, which extend in the direction of inclination of the grate. In the embodiment shown, an inclined grate for an incinerator has rows of movable and fixed grate bars. Rotatably mounted on the fixed grate bars 6 are sector-shaped raking elements 7 spaced at intervals from each other in the longitudinal direction of the grate bars 6. Each sector element has a shaft 8 acted upon by a lever 9 which in turn is connected to an operating rod 10. One of the radial boundary surfaces of each sector-shaped element 7 forms a continuous plane with the material supporting surface of the fixed grate bar 6 and when the operating rod 10 is displaced by hand or by a motor the elements 7 are deflected upwardly so that they project above the material supporting surface as shown in broken lines 7<SP>1</SP>. The sector-shaped elements 7 may be pivoted in opposition to the inclination of the grate so that when operated they exert a pushing-back force on the material on the grate or they may be pivoted with the inclination of the grate to give an additional feeding movement. In a modification, the boundary surface of the element 7 forming a continuous plane with the grate bar 6 is provided with a flat portion 34 which may project over the edges of the grate bars as in Fig. 7 or may be recessed into the surface of grate bar. In another modification, Fig. 8, discshaped elements 43 are provided in recesses 42 of fixed fire grate bars 37 and operated by studs 40, this embodiment being particularly suitable for producing vibrating movements of the elements 43. The raking elements 7 may also be operated at such a speed as to produce a vibrating movement on the grate.
