Title: Improvements in electric transformers regulatable by varying the active number of coils
IPC: H01F29/04
Filed: 1925-12-24
Abstract: 268,039. Hering, E. Dec. 24, 1925. Regulating transforrmers :-A variable ratio transformer comprises a winding having tappings for varying the number of active turns by coarse steps, and two separate winding sections with tappings for fine adjustment, switch means being provided whereby the separate sections may be brought into circuit with the main winding alternatively. The Fig. shows an autotransformer in which the main winding is tapped and connected to contact studs 1, 2, 3 cooperating with sliding contacts A, B. The separate winding sections for providing fine adjustment are connected to studs a - - f cooperating with a contact K. With the contacts in the position shown the secondary circuit comprises the whole of the turns between the tappings 1, 2 with the addition of two sections of the fine adjustment winding. A further section of the latter winding is added by movement of the contact K on to the stud c. Further movement of the contact K on the stud d produces an arrangement in which the secondary circuit comprises the turns between tappings 1, 3, and the two reversed sections of the fine adjustment winding. The reversed sections of the fine adjustment winding are cut out in succession by further movement of the contact K until the stud f is reached. This produces a continuous increase in secondary voltage which may be further continued by moving along the contact A to stud 3 and moving the contact K forward on to a stud a &c. so as to add sections of the fine adjusting winding to the turns between tappings 1, 3. The movable contacts may be mechanically interconnected with each other. The contact K is connected through a resistance to an auxiliary contact to avoid short circuiting a part of the winding.

Abstract: 1474055 Nuclear fuel HOBEG HOCHTEMPERATURREAKTOR BRENNELEMENT GmbH 25 July 1974 [27 July 1973] 32824/74 Heading G6C A nuclear fuel body is made by covering coated particles of nuclear fuel and/or fertile material with a mixture of graphite powder and a thermoplastics resin binder, treating only the surfaces of the particles with a hardener for the resin and a lubricant, and consolidating the particles in a mould at about 150‹ C. The body comprises the coated particles embedded in an isotropic radiation-resistant graphite matrix of high density, strength, and thermal conductivity. Part of the mixture of graphite powder and resin may be formed into a granulate, treated with hardener and lubricant, and added to the fuel particles before consolidation. The resin binder may be a phenol-formaldehyde resin which softens on heating, the hardener hexamethylene tetramine or formaldehyde, and the lubricant stearic acid paraffin oil, octadecanol, or soybean oil. The hardener and lubricant may be used dissolved in a solvent, e.g. water or methanol. In examples, coated UO 2  and ThO 2  particles are covered separately with a mixture of methanol, graphite, graphitized petroleum coke, and the binder, and treated with the hardener and lubricant; the fissile and fertile covered particles are mixed, compressed in a cylindrical mould at 150‹C., removed from the mould, and heated to 1800‹ C.

Title: Improvements relating to the grinding of cement raw meal, cement clinker or other materials
Inventor: FRANKERT OTTO PEDER
IPC: B02C17/00
Filed: 1954-11-17
Abstract: 808,061. Treating cements. SMIDTH & CO. A. S., F. L. Nov. 15, 1955 [Nov. 17, 1954], No. 33314/54. Class 22. [Also in Group II] Apparatus for the removal of heat generated by grinding cement raw meal, clinker, or other materials, comprises a grinding chamber, a filter, a pipe leading from the chamber to the filter, and thermal insulation on the pipe and filter to prevent condensation therein of the vapour of water or other evaporable substance which is supplied to the mill to absorb some of the heat generated. In the figure a mixture of cement clinker and gypsum is introduced into a tube mill 1 through inlet 2. Water flows from a tank 6 situated at a level below the chamber 1 and is atomized at 18 by compresssed air supplied through a pipe 11, the water being introduced into the chamber when the temperature therein due to grinding, is about 100‹C. Ground cement leaves the mill 1 via a trunnion 3 and passes down shaft 4 to a conveyer (not shown). Cement dust, water vapour, compressed air and anyair sucked in through inlet 2, pass up pipe 20 to an electrostatic filter 21 connected to a fan 22, the filter trapping the suspended cement dust from which it is discharged by a worm conveyer 23 designed to exclude the direct entry of atmospheric air. The filter is provided with heating elements 28. The temperature of the cement mix being ground is maintained between 100‹C. and 130‹C. to prevent loss of water of crystallization from the gypsum and condensation inside parts 19 to 22. A layer 27 of insulating material reduces heat loss. Thermometers 24, 25 and 26 assist maintenance of optimum working temperatures by giving impulses to an alarm device when the desired temperatures are not met. In a modification, not shown, the grinding is carried on in closed circuit, the ground material being fed from the pipe 4 to a separator from which the finer material is blown into a dust precipitator, while the coarser material, after the addition of evaporable substance, is fed into the inlet 2 for further grinding. Spraying of material before its introduction into the grinding chamber is applicable to the invention generally. When water is used for cooling purposes it can be atomized solely by pressure, without compressed air. Water may be present in the material to be ground, i.e. it may be supplied with the material and not separately. Mixtures of cement clinker, gypsum, and trass or other pozzolana exemplify such material. Reference is also made to the grinding of limestone and phosphate-bearing rocks.

Abstract: 642,581. Walls; building-slabs. BARKER, G. G. (Durisol Akt.-Ges. fur Leichtbaustoffe). Nov. 8, 1946, No. 33323. [Classes 20(iv) and 87(i)] In load bearing walls built of prefabricated light-weight units of wall thickness and storey height, each unit has a main core portion of fibrous cement bound material which is stiffened on one or both faces with a layer of cement or plaster, one or both such layers being locally thickened inwardly to provide reinforcing columns at the side edges of the unit extending the full height thereof, but leaving the core of fibrous material extending continuously from one side edge of the unit to the other. In the wall shown in Fig. 1, each unit has a core 1 e.g. of mineralized wood particles, an outer stiffening layer 2 of cement mortar and an inner stiffening layer 3 of plaster. The core may be solid or provided with spaces 4. Reinforcing columns 5 of concrete or reinforced cnocrete are formed integrally with the core at the corners of each unit and, where necessary, intermediate columns 6 may also be provided (Fig. 2). The vertical joint faces of the units have grooves 7 into which are cemented tongues 8 of flexible material e.g. bituminised felt. Recesses 9 for grouting are also provided adjacent the outer corners of the units, the spaces between them on the inner side of the wall being pointed with plaster at 11. In Fig. 4, the wall is built of alternate wide and narrow units, the latter forming columns and having outer and inner concrete layers 15 and 16 provided with reinforcing bars 18 tied by wires 19. In the wider units, steel bars or wooden battens 20 may be inserted to strengthen the light weight core. The units are grooved at top and bottom edges (Fig. 8) to provide for a mortar filling and reinforcing bar 26, which ensures their alignment.

Abstract: 1411709 Aperture correction SONY CORP 12 July 1973 [13 July 1972] 33390/72 Heading H4F It is stated that whereas a prior art aperture correction circuit such as shown in Fig. 1 will produce (Fig. 2F) suitable symmetrical steepenings in the rise and falls of a hypothetic symmetrically distorted square wave such as shown at Fig. 2B, a realistic distorted square wave such as shown at Fig. 3B having a steep rise and gradual fall is incorrectly processed and gives the unsymmetrical output shown at Fig. 3F. The circuit of Fig. 4 is thus proposed wherein the asymmetrical video input signal Sb, Fig. 6A, is combined with its differential in adder circuit 7 to give the partially corrected waveform shown at Fig. 6C. This is further differentiated, inverted, and combined with the origonal video signal in adder circuit 2 to give the symmetrical corrected signal shown at Fig. 6F. If the rise in the input pulse is more gradual than the fall, then the adder circuits will be changed to subtractors.
