Abstract: 407,976. Controlling the calorific value of gas. BLAKELEY, SONS, & CO., Ltd., F., Church Fenton, near Leeds, and BLAKELEY, W. F., The Hawthorns, Little Fenton, South Milford, both in Yorkshire. Sept. 27, 1932, No. 26752. [Class 55 (ii).] A gas of predetermined calorific value is obtained by automatically controlling mixtures of gases of different calorific value, the moving arm of a recording calorimeter using the mixed gas actuating a valve by electrical control to admit or shut off one of the gases forming the mixture. The arm B of a recording calorimeter fed with the mixed gas, on movement in one direction causes a stirrup d<1> to dip into a mercury cup d<3> and close on contact to allow current from an accumulator F to pass through a solenoid E and move the armature e of a relay to energize a solenoid G. The core g is thereby attracted and moves, by a cable g<2>, a valve H which controls the supply of one of the gases. A pin g<3> on the core engages a lever j<4> which lowers a rod j separating spring contacts J and cutting off the current to the coil G when the operation is completed. Similarly the valve H is moved in the reverse direction with reversal of movement of the pointer B. In a modification, switches of the tilting mercury type are employed.

Abstract: 781,404. Packaging machines. WRIGLEY J. R. CO., W. Sept. 26, 1955 [Nov. 5, 1954]. No, 27333/55. Class 94(1). [Also in Group XXIV] A machine for packaging groups of articles in boxes comprises two rams, one acting to place an empty box on a holder while removing a filled box from the holder, and the other operating transversely of a conveyer feeding forward the articles, to move articles from the conveyer onto a platform and then to sweep them from the platform into the box. The empty boxes 36 are fed down an inclined shoot 83, Figs. 1, 2, 11 onto a surface 84 of the ram 85. As the ram advances, its forward edge 144 removes a filled box from the holder 86. A spring tongue 146 retains the empty box in the holder 86 as the ram 85 withdraws. The articles 35 are brought by a conveyer belt 73 opposite a ram 87 for transfer to the platform 88 and holder 86. The articles which are to be packed lie transversely of the belt 73 and are halted opposite the ram 87 by a stop 82, Figs. 1, 20. The ram 87 is camoperated to give alternate long and short feeding strokes. A first stroke feeds a group of five articles onto the platform 88 and a second longer stroke feeds a second group of articles from the belt 73 across the platform 88 so that both first and second groups are deposited in the box, Figs. 20, 24-26. The next two strokes feed in a second layer of articles, Figs. 28, 30. As the ram 87 moves forward, gate elements 168-170, Fig. 13, in a housing 80, Figs. 1, 2, 13, drop individually behind it to stop articles advancing with the. belt 73. As the ram retracts, it engages a lever 211 to raise all gate elements simultaneously to permit articles to proceed to the stop 82. The box holder 86 is carried on a pivoted lever 214 and moves towards and beneath the platform 88 during filling of a box. A finger 228, Fig. 7, operates to press an empty box down into the holder, Fig. 24, and to engage each layer of articles entering the box, Figs. 26, 30, to ensure that they are correctly positioned. The filled boxes may be ejected from the machine onto a belt 304, Fig. 20. taking the output from several similar machines. A cam 296, Fig. 2, operates a switch causing grippers 303, Fig. 20, to engage boxes from other machines so that a gap is left on the belt 304 to receive an ejected box. The machine includes an overload clutch 49, Fig. 1, (see Group XXIV), which may also be hand operated to disengage the machine from its driving motor 39, and a clutch 249 (see Group XXIV) which operates to stop both rams in the event of a gap occurring between articles on the belt 73. Rollers 243, 245, 147, Fig. 2, run over the articles and one of them dropping into a gap stops the rams,. while the belt continues to operate. A wheel 124 enables the machine to be turned over by hand. Specification 733,375 [Group II] is referred to.

Filed: 1927-10-19
Abstract: 279,465. Franke, P., (Assignee of Weindel, A.). Oct. 21, 1926, [Convention date]. Treating-materials ; plant.-Tarry liquors from coking and gas works are treated with a tar oil fraction boiling over the range 240‹-320‹ C. to extract tarry matter, phenols and pyridine bases. The tar oil may be treated before use by soda to remove any contained phenol, and then by a dilute acid to remove pyridine bases, and any naphthalene present may be removed by crystallization. The treatment of the tarry liquors is effected at ordinary or slightly raised temperature, and the liquids may be caused to flow through one another in counter-current, for instance in a tall cylindrical tank, the tar oil being suitably distributed at the top. Or the treatment may be effected in a conical tank a having inlet pipes b, c, d and outlet pipes b<1>, c<1>, d<1> with a rotary stirrer f at the level of the pipes c, c<1>. Soda lye is supplied at d, tar oil at c, and the tarry liquor at b, the liquids forming three layers as shown. The stirrer causes relative motion between the layers, whereby the phenols pass from the liquor to the oil and from the oil to the soda solution. The pyridine bases are recovered by treatment with an acid, the oil being drawn off for this purpose continuously or intermittently. When the liquor is supplied continuously, baffle plates w may be arranged so as to make the path of the liquor long. Several of these apparatus may be arranged in series. Alternatively the oil may be treated by vacuum distillation to remove the extracted phenol and pyridine bases. After the oil treatment, the water may be calcium carbonate, silica, or organic substances such as coal dust. Specification 266,004, [Class 55 (ii), Gas manufacture &c.], is referred to. The Specification, as open to inspection under Sect. 91 (3) (a) gives the boiling-point of the tar oil as 230-350‹ C. This subject-matter does not appear in the Specification as accepted.
