Abstract: 128,594. Graham, E. A. Aug. 4, 1916. Order and order-type apparatus.-In electric signalling-apparatus, especially applicable to signalling orders or numerical data, of the type in which the receiver comprises a number of electromagnets energized and de-energized in predetermined order to impart rotary movement to an armature, the electro-magnets are in series and are de-energized as required by a transmitter which short-circuits instead of breaking circuit. Specification 125,454 is referred to. As shown, six electro-magnets are arranged in pains 1, 2, 3 in series with a battery 11. The transmitter comprises two contact members 12, 13 recessed as shown, carried by, but insulated from, a spindle 14, and adapted to co-operate with contacts connected to the points 9<a>, 9<b> as shown. The members 12, 13 carry segments 12<a>, 13<a> adapted to contact intermittently with brushes 3<c>, 1<e> respectively connected to the points 3<b>, 1<b>. As shown, the points 9<a>, 1<b>, are connected through the member 13, so that the electro-magnets 1, 2 are shortcircuited and de-energized, the magnets 3 being energized. As the spindle 14 is rotated, the arrangement shown energizes the magnets successively in the order and grouping 3; 3, 1; 1; 1, 2; 2; 2, 3.

Title: Improvements in or relating to electro-magnetic regulating apparatus
IPC: H02P9/22
Filed: 1933-01-28
Abstract: 414,111. Automatic electromagnetic regulators. STONE & CO., Ltd., J., Deptford, and CHILTON, A. H., 200, Brompton Road, both in London. Jan. 28, 1933, No. 2748. [Class 38 (iv).] In a carbon pile regulator operated by an electromagnetic actuating force, the rotor is cylindrical in form with convex end faces. The iron magnet core 2 carries the exciting winding 3 upon a forward extension and the rotor 7 located between the pole-face 8 is connected by a spindle to a disc 16. The concave pole faces of the electromagnet match the convex faces of the rotor to give an air gap of constant thickness so that the magnet has a declining characteristic corresponding to the upper or lower portion of a sine curve. The disc 16 is connected by a crank pin 18 to the push rod 19 of the carbon pile 21. The carbon discs 21 are arranged between a top plate 22 and a compression plate 20 and confined by insulated pins 30 at the side. The top plate 22 of the carbon pile is pivoted at 24 to a vertically adjustable bracket 25. The controlling helical tension spring 32 is connected between the metal tape 33 which is anchored to the disc 16 between radiused blocks 34, and an adjustable attachment bracket 35. The disc is also connected by a crank pin 36 to the piston of a pivoted dash pot 37. The contraction of the spring which moves on one side of the dead centre has a characteristic obeying the sine curve law and matches the motion of the rotor. Compensation for thermal expansion of the carbon pile and its connection is obtained by use of the device described in Specification 414,112, [Group XXXVI].

Filed: 1937-01-30
Abstract: 474,720. Moulding slabs by extrusion. BARBOUR, J. A., and SOUTHHOOK POTTERIES, Ltd. Jan. 30, 1937, No. 2768. [Class 87 (ii)] [Also in Group XV] In moulding clay slabs for refractory or other purposes clay is extruded ir the form of a hollow block comprising three, four, or more slabs A, Al, A<2> joined together at their backs by webs B or fragile connecting brackets beyond which the edges f of the slabs protrude without meeting. The slabs are separated by breaking the webs B. Smooth finished edges can thus be formed by extrusion and breakage of the webs does not interfere with the edges. The thickness of the webs may be reduced at the junctions b with the slabs, and the webs may also be weakened intermediately as at c. The slabs may be broken apart before or after firing. The edges may be square, bull-nosed, checked or of other shape. The edges of a slab may be dissimilar. The extruding die and core are shaped as required and may be plain, grooved or serrated.
Patent GB-401138-A (GB)
Title: Process for producing and accelerating the alcoholic fermentation of distillery musts
IPC: C12P7/06
Filed: 1933-01-28
Abstract: The yield of alcohol obtained in the fermentation of distillery musts is increased by adding salicylic acid or one of its derivatives such as sodium salicylate, b -naphthol salicylate, or phenol salicylate to a fermentable must in an amount equal to 1/40,000 part thereof, and after the fermentation has commenced, adding a further quantity of must which has been treated with salicylic acid or a derivative thereof in the same proportion, transferring a portion of the contents of the fermenting vat to another vat and adding salicylic acid or a derivative to bring the proportion of antiseptic up to 1/10,000, allowing the destruction of undesirable fermenting organisms to proceed with diminished fermentation under the influence of salicylic acid or derivative in this proportion for a time, and then making up the contents of the vat with fresh must or juice so that the acid content is finally brought back again to 1/40,000, at which concentration the fermentation proceeds normally.  The process may be applied alone or in combination with other processes for the treatment of the musts.  An example is given.  The Specification as open to inspection under Sect. 91 comprises also the use of salicylic acid or its derivatives as antiseptics for the treatment of musts other than distillery musts and for fermentation liquors from apples, beet roots, and sugar canes, the addition being made in the latter instances after the rasping operation or to the liquors or small juices returned to the rasped product and subsequently supplied to the diffusion batteries, the ducts, pipes, and batteries being thus disinfected by the passage of the salicylated must.  The addition of salicylic acid or a derivative thereof in a proportion of 1/40,000 to pure ferments employed as additions for bringing about the fermentation of musts is also described, the must to be fermented being also treated with the antiseptic before pouring on to the purified ferment. This subject-matter does not appear in the Specification as accepted.

Title: Destructive distillation of coal
IPC: C10B49/04
Filed: 1962-01-25
Abstract: <PICT:0953781/C3/1> A continuous process for the destructive distillation of coal comprises passing the coal progressively upwardly through a vertical treatment zone, introducing an oxygen-containing gas (air) into the coal at an intermediate location 42a  to flow co-currently with the coal, establishing a combustion front 50 of limited vertical extent in the coal tending to move counter-current thereto, oxygen being consumed in the front to provide an oxygen-free zone behind the front through which the coal passes, directing hot gases, e.g. the products of combustion, through the coal leaving the front 50 to maintain distillation temperatures, removing evolved products (coal tar, coke-oven gases, combustion products) at 44 separately from the coke, and cooling the coke, e.g. by water quenching at 47, before discharge.  The position of the front 50 is stabilized by regulating the input of air at 42 and by establishing a balance between the coal input and solids output.  The temperature of the front 50 and the rate of coal feed, of coal movement, and of solids removal, may be automatically controlled. Recycled coke oven gas may be included in the air delivered, and the coal, which moves upwardly, may be preheated at 41, e.g. by recycled gas.  The retort 34 is surrounded by an insulating chamber 40 having a water jacket 43. Rapid, intermittent charging takes place at the inlet 37 (see Division F4). In two further embodiments, coal passes downwardly and breakers, e.g. rolls, are included near the bottom of the retort, see Figs. 2, 4 (not shown), and the outlet corresponding to 44 has a baffle to prevent entry of solids. Temperatures of 1100 DEG  F. to 2000 DEG  F. are mentioned for the front 50, and gases flow away from the front to the outlet 44 by virtue of an exhaust pump in the outlet line or by making a high pressure in the bottom of the chamber 40 by suitably sealing the solids outlet.
