Abstract: 699,505. Coke ovens. LITTERSCHEIDT, W. July 2, 1949 [July 2, 1948], No. 18312/52. Divided out of 699,451. Class 51(ii) In a regeneratively fired coke oven, a uniform distribution of gases passing either from the bus flues to the regenerators or in the reverse direction, is obtained by giving the floor of each bus flue 2 a parabolic shape, the regenerator ports 3 being substantially vertical and of substantially equal cross-sectional area. The ports may be so shaped that they present a different flow resistance in each direction of gas flow. In a modification, Fig. 2, each bus flue 2 comprises a hollow iron casting having ports 4 in its upper face the position of which relative to the regenerator ports 3 is varied due to the differing co-efficients of expansion of their respective materials. Further modifications, Figs. 3-5 (not shown), have superposed metal plates in which the relative position of the ports 3 and 4 is varied either by reversing the relative position of the plates when the gas flow is reversed, by fixing opposite ends of each plate into the ambient brickwork leaving the other ends free, or by fixing the front ends of both plates and making said plates of materials having different co-efficients of expansion.

Abstract: 460,708. Current transformers; calibrating meters. ALLGEMEINE ELEKTRICITATS-GES. July 1, 1935, No. 18786. Convention date, June 30, 1934. [Class 38 (ii)] [Also in Group XXXVI] A portable transformer for measuring A.C. or D.C. in straight conductors comprises a pair of annular cores 2, 3 divided so that they may be placed round a conductor 11 carrying the current to be measured, the cores carrying a pair of oppositely connected auxiliary excitation windings 4, 5 and a pair of series-connected secondary windings 7, 8. When D.C. is to be measured, the auxiliary windings 4, 5 are fed with A.C. from an auxiliary source (such as a commutator switching arrangement mounted on the transformer) so as to produce alternating fluxes acting oppositely on the secondaries. The additional effect of the D.C. in the conductor 11 is to produce a resultant alternating flux which produces a voltage at the secondary terminals proportional to the D.C. flowing. When A.C. is to be measured the auxiliary windings 4, 5 are disconnected. The core parts may be hinged together and provided with handles to form tongs. A measuring instrument may be mounted on the transformer. The instrument may be calibrated by comparison with current readings obtained by passing current through an ampere-hour meter for a measured period of time and dividing the meter readings by the time. To facilitate calculation, the number of units of time during which current is allowed to flow is made equal to the transformer ratio, or to a simple fraction or multiple of it.

IPC: A24C5/18
Filed: 1959-06-03
Abstract: 958,208. Cigarette-making machines. MOLINS MACHINE CO. Ltd. June 2, 1960 [June 3, 1959], No. 19063/59. Heading A2C. Means for sensing long-term variations and short-term variations in the mass for unit length of a tobacco filter operate control means e.g. a trimmer, to reduce the variations in the filler. In Fig. 2 the filler is formed by suction on a perforated band 1 and the variations in the mass per unit length are sensed by a suction box 70 which draws air through the filter, the variations in mass producing variations in pressure in the box 70 which are transmitted through a pipe 74 to a pressure responsive capsule 75, Fig. 7, which responds to short-term variations, and through a restriction 132 to a capsule 131 which responds to long-term variations. The capsules act in tandem on a lever 133 which operates through a rod 80 the control valve 105 of a servomotor 103 the output 111 of which controls through a shaft 114 and rod 51, a lever system 42 which adjusts the level of trimming blades 27 and associated brush 28. When the pressure in chamber 70 rises, indicating a smaller mass per unit length of filter, the trimmer 27 is moved away from the band 1 to trim off less tobacco to produce a more constant mass per unit length in the trimmed filler. The discs 27, Fig. 4, are carried by a yoke 36 connected to a lever 39 which is fixed to a shaft 40 having an arm pivoted to the mid point of lever 42 connected to the adjusting rod 51. A lever 59 pivoted at 57 and connected at one end to the yoke 36 adjusts the position of brush 28, through a link 55, in consonance with the discs 27. The discs 27 may have recesses 29 to produce dense-end cigarettes. The pressure variations in box 70 are effective almost immediately on the short-term responsive capsule 75 but are damped by restriction 132 so that only long-term pressure changes affect capsule 131. In a modification, the capsules 75, 191, are arranged in series. The device is also shown applied to a system in which the filler is formed by showering tobacco on a belt. Specifications 895,733, 909,222, 916,141 and 929,338 are referred to.
