Title: Improvements in or relating to high chambered coking retort ovens
IPC: C10B21/22
Filed: 1962-04-13
Abstract: 981,071. Coke ovens. KOPPERS CO. Inc. April 13, 1962 [April 13, 1961], No. 14463/62. Heading F4B. In a Kopper-type coke oven, the heating flues are divided by partition walls 14 into vertical heating flues, adjacent flues being fed by riser ducts 23 within the partition walls terminating in elevated ports 24, 25 arranged to open upwardly into the flues to give gas flows parallel to any gas flow from low burner parts at the base of the flues. In a regenerative compound cross-over coke oven, Fig. 1, the regenerators 8 are arranged in groups of three, a lean gas heating regenerator G feeding low burners through a duct 26 and high burners through ducts 28 and risers 23, being flanked by smaller air heating regenerators A, A, one of which feeds the low burners through ducts 27 and the other feeding the high burners via ducts 29 and risers 23. This ensures that the waste gases are not fed to regenerators adjacent to those heating combustible gas. The high burners may all be at the same level, or the burners fed through adjacent partition walls may be at different levels, so that each vertical flue is fed with gas at two elevated burners and at the bottom, Fig. 4, not shown. The size of the ports 24, 25 is controlled by throttles adjustable through holes 7 in the oven roof, interchangeable throttle blocks 36, or sleeves 49, Fig. 10, resting in shoulders formed in ledges 35 at the top of the thickened lower part of the partition walls 14 which accommodates the riser ducts 23. The high burners may be controlled by sliding throttle blocks, Fig. 11, not shown. The thickened parts of the partition walls are spaced from the walls of the coke chambers, and may be offset towards one or other coke chamber wall so as to facilitate adjustment of the lower burners by replaceable plugs 42 and of the rich gas throttles 30.

Title: Improvements in or relating to self-balancing bridge arrangements
IPC: F24H9/20
Filed: 1941-11-21
Abstract: 585,789. Capacitance measurements ; condensers. BLUMLEIN, D. [Representative-of BLUMLEIN, A. D.], CONNELL, W. H., and HOLLOWAY, D. G. Nov. 21, 1941, No. 14981. [Class 371 [Also in Group XXXVIII] In a self-balancing bridge, out-of-balance voltages or currents are caused to adjust a balancing component so as to tend to maintain the bridge balanced, the balancing component having a non-linear characteristic including a portion of low slope and a further component connected in the bridge so as effectively to oppose the balancing component is arranged to be adjusted by the out-of-balance voltages or currents so that the admittances of these two components are changed in opposite senses whereby the characteristic of the balancing component is effectively modified so as to increase the slope of the portion of low slope. The self-balancing bridge shown in Fig. 1 is of the kind described in Specification 581,161, in which a capacity 1 between two electrodes (not shown), which is a function of the height of an aircraft above a conducting surface, is measured by means of a bridge having tightly coupled inductive ratio arms 2, 3 and an adjustable balancing capacity. The balancing capacity comprises a moving electrode 5 and two. fixed electrodes 6, 7 connected to the ratio arm 3 and to a tapping on the ratio arm 2. Out-of-balance voltages are picked up in a coupling coil 8 and passed through an amplifier 9 to the operating coil 10 of a current meter movement attached to the electrode 5. The effects upon the bridge balance of the two halves of the differential condenser 5, 6, 7 are opposite and unequal and combine to produce an approximately linear relationship between the condenser setting and the height of the aircraft. The differential condenser may be of the form shown in Figs. 2 and 3, in which a weak current meter movement 11 has an insulating pillar 12 fixed to the moving element and carrying a light conducting pointer 13. The pointer 13 projects through a radial slot 14 in the earthed conducting structure 15 comprising two parallel metal plates joined on their straight and inner semicircular edges by a metal strip containing the slot 14. Two electrodes 16, 17, in the form of small slotted blocks are supported in an insulated manner within the structure 15, the slots preventing contact with the pointer 13. Instead of connecting the electrode 7 to a tapping on the ratio arm 2, a capacity potentiometer may be introduced between the electrode and the bridge. The bridge voltage applied to the moving electrode 5 need not be the same as that applied to the capacity 1 and may be reduced by a step-down transformer or capacity potentiometer. The electrodes 16, 17 may be of different sizes to give different variations of capacity without requiring the application of different bridge voltages or the use of different tappings on the ratio arms. Separate elements may be employed instead of the differential condenser. One or more of the adjusted elements may be variable inductances or resistances.

A high frequency magnetic core comprises by weight 60-75 per cent of Fe 2 O 3'  10-25 per cent of ZnO and 15-25 per cent of one or more of MgO, MnO 2 , Ni 2 O 4  and CO 2 O 3 . A mixture of the powdered oxides is heated at 2200-2500 F. for 2 or more hours. The product is again powdered, mixed with a binder, moulded to any desired shape, heated at about 1900-2200 F. for at least one hour and slowly cooled at say 100 F. per hour. The binder (2-8 per cent of the mixture) may be organic material such as the phenol-aldehydes, urea or melamin aldehydes, vinyl material or polystyrene and be burned off during heating. The product when used as a core in a tuned circuit increases the tuning range and has an increased value of Q. If oxides of lead and titanium (lead titanite) are added (2-12 per cent), the mechanical strength is increased, and the thermal drift of the tuned circuit is reduced, while the tuning range and Q continue to show improvement over their normal values. Examples of manufacture are described where the metals whose oxides are used in addition to those of iron and zinc, are nickel or cobalt or magnesium and manganese together. Values of above-mentioned properties of each example are set out in the Figures (not shown).
