Title: Improvements in or relating to the manufacture of finely divided active carbon
IPC: C01B32/336
Filed: 1929-01-25
Abstract: 304,791. I. G. Farbenindustrie Akt.- Ges. Jan. 2C, 1928, [Convention date]. Carbon.-In the production of carbon in finely divided form by catalytic decomposition of carbon monoxide or gases containing it, metals of the eighth group of the periodic table, more par. ticularly iron, nickel and cobalt, in a carefully reduced and finely divided form are used in admixture with difficultly reducible metallic oxides, e.g. alumina, or magnesia, as catalysts; normal or increased pressure is employed. The temperature used may be 300-350‹ C. The carbon obtained has active properties and by adding hydrocarbons, e.g. methane, to the gas a carbon of increased activity and of deep black lustre is produced. the hydrocarbons not necessarily taking part in the reaction. The carbon may be treated with acids, to recover the catalyst therefrom, and washed and dried without loss of activity. The waste gases from the reaction, which still contain carbon monoxide, may be passed over a fresh contact mass to obtain further carbon. An example is given in the Specification. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of the metals as catalysts without addition of the oxides. This subject-matter does not appear in the Specifcation as accepted.

Filed: 1944-02-14
Abstract: 605,935. Automatic-control systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 14, 1944, No. 2746. Convention date, Jan. 5, 1943. [Class 38 (iv)] [Also in Groups XXXVII and XXXVIII] Temperature.-A Ferraris disc relay is operated one way or the other from a central position by the selective short-circuiting of two secondary windings 5, 6, which enclose part of the flux produced by a primary winding 2, and the rotation of the disc 8 causes by means of a cam 12 the operation of contacts 13, 14, 15 which also selectively short-circuit the windings 5, 6. In the form shown the windings 5, 6 are short-circuited respectively by the closing of contacts 21, 22 or 21, 23, which is done by a thermostat as the temperature rises or falls. The disc 8 then rotates and the cam 12 moves so as to short-circuit the other winding 6 or 5 through a resistance R. This tends to rotate the disc 8 back but owing to the resistance R the effect is overpowered and the disc continues to rotate till contacts are operated, say to cut-off a heater. As the temperature drops contact 21 assumes its central position, removing the short circuit from winding 5 so that winding 6 now has effect and the disc 8 returns to its central position when contacts 13, 14 open and the disc stops. A return plate 7 for the magnetic flux is provided and this may consist of a simple plate as shown or an E-shaped core similar to that carrying the windings 2, 5, 6. The Specification as open to inspection under Sect. 91 comprises also a modification wherein contacts 22, 23 are connected to the ends of a potentiometer resistance along which contact 21 slides and a similar potentiometer resistance is arranged across the contacts 13, 15, along which resistance the contact 14 slides. Movement of the contact 21 causes a lack of balance in the short circuiting of coils 5 and 6 so that the disc 8 moves till the contact 14 has moved a corresponding amount. This subject-matter does not appear in the Specification as accepted.

Patent GB-395774-A (GB)
Title: A new or improved process for the preparation of soft rubber
IPC: C08K3/28
Filed: 1932-02-03
Abstract: A soft rubber is obtained by adding sodium or other nitrite to latex prior to coagulation with an acid.  The softness and plasticity of the rubber depends on the amount of nitrite added, the amount of coagulant, and the period between coagulation and working-up.  0,1 per cent sodium nitrite has an appreciable effect, 1 per cent yields a very soft product.  Insufficient acid to react with all the nitrite produces a harder rubber, as does also an excess of acid.  The longer the coagulum remains in the serum before machining, the softer is the product.  The speed of the reaction may be increased by heating the coagulum, e.g. by boiling or by heating in an autoclave to 180 DEG C.  Specification 395,775 is referred to.

Title: Improvements in automatic induction train control systems
IPC: B61L3/12
Filed: 1921-01-27
Abstract: 171,348. Shaver, A. G. Nov. 8, 1920, [Convention date]. Track apparatus for stopping trains. -In a train-control system the track and train carry induction apparatus so arranged that the inductive coupling will initiate the operation of the train-controlling means even when the track is clear. The track apparatus at each point consists of a permanent magnet M with an energizing coil C, and coils 60', 62<1> wound on iron cores and connected through tongues 66, 67, 68 controlled by relays D, H associated with the distant and home signals. The train carries a brake valve 26 controlled by an electromagnet 24 the circuit of which is completed by relays 16, 9 under the control of magnet switches 5, 12 operated by the track apparatus; coils 64, 67a associated with the switches are connected to the battery 1. Indicating lamps G, Y, R are also provided. On entering a section the magnets 5, 12 are thrown by the magnet M to the position shown in dotted lines and the relays 9, 16 are thereby de-energized. Immediately afterwards, however, the cores of coils 60, 62 cover the track electromagnets 60<1>, 62<1>. With the track clear the relay tongues 66, 68 are held up and the coils 60, 60', 62<1>, 62 act as transformer sets and current is supplied from the coil 62 to the coils 64, 67a. The coil 64 holds the magnet switch 12 open, but the coil 67a closes the switch 5 which permits the relay 9 to be energized. The relay contact 48 completes the circuit of the coil 54 which closes the magnet switch 12 and the relay 16 is energized. With relays 9, 16 energized the circuit of the electromagnet 24 is complete and the valve 26 is placed in its normal position and the green light is shown. This action is repeated and the efficiency of the apparatus is checked at each signal point on the clear track. When the condition of the block is such that the speed should be restricted the relay D is de-energized. This has the effect of reversing the connections between the coils 60<1>, 62', and the coils 64, 67<a> act to close the magnet switch 12 and hold open the switch 5. The relav 9 therefore remains down while the relay 16 moves up and connects the valve magnet coil 24 in series with the speed controller 45. If the speed rises above a predetermined value, contact is broken by this controller and the valve 26 is operated. Under stop conditions the relay H is de-energized and connection between the coils 60<1>, 62<1> thereby broken. The relays 9, 16 and the coil 24 are de-energized, the brakes applied, and the red light R is shown.
