Title: Improvements in the manufacture of hydrogen or of gases containing hydrogen from methane and similar hydrocarbons or gases containing these hydrocarbons
IPC: C01B3/22
Filed: 1929-10-03
Abstract: <PICT:0341462/III/1> Hydrogen or gases containing hydrogen are obtained by the alternate supply of air and hydrocarbon gas, with or without steam, to a bed of coke or refractory material, the blow gases being burnt with secondary air in an annular chamber surrounding the bed of coke or the like.  Hydrocarbon gas is introduced at 10, is preheated by passage through an annular jacket 2 and enters a generator 1 by ports 6.  It is cracked by contact with the hot filling material, carbon being deposited, and the hydrogen obtained leaves the apparatus by ports 8 and/or 9.  The gas supply is then cut off and, if necessary, after a purge with steam, air is introduced at 8 and burns the carbon to carbon monoxide which passes through the ports 6 and is burnt by the secondary air introduced at 5.  After again purging with steam the cycle is repeated.  If inert gases or steam are admixed with the hydrocarbons, a bed of coke is employed, incoming coke being preheated by the portion of the converted gases leaving at 9. Specifications 195,798 and 328,643, [both in Class 55 (i), Coking &c.], are referred to.

Class 38(5) [Also in Group XXIX] A temperature regulator for cookers comprises a thermal element e.g. the phial and diaphragm 38, 32 for operating a control means e.g. the valve 24 or an electric switch, controlling the temperature in the cooker, a rotatable shaft 44 carrying a knob 52 for adjusting the position of the element for setting the cooker temperature, a pair of relatively movable members 46, 66 bearing a reference mark and temperature indicia respectively, one being stationary while the other rotates with the knob and manual means for relatively rotating through a predetermined angle the other members with respect to the shaft and having visual indications for indicating correspondence between different positions of the manual means and specified classes of cooking utensil having different heat-absorption properties, so that when the manual means is in a position corresponding to one class of cooking utensil the control means maintains a temperature as indicated whereas in a position corresponding to another class of utensil the control means maintains a temperature differing from the indicated temperature by an amount necessary to allow for the difference in heat-absorption properties. The member 66 is turned on the knob 52 against the frictional grip of a spring 70 by a handle from a position in which dots on the knob and member are in line for shiny utensils to a position in which diamond marks are in line for dull utensils, the turning being limited by a lug 78 on the knob entering a slot in the member. In a modification a pushbutton in the knob projects for shiny and is pushed in for dull utensils, the button being spring loaded outwards and having a pin and slot connection with the knob and cam slots engaging pins on the shaft 44 so that inward movement of the button rotates the knob and alters by a predetermined amount the relation between a reference mark on the valve casing and a temperature scale moving with the knob.

The lifting platform of a garage lift is provided, on the underside, with insulated conductor bars 13 connected to a capacitative switch 14 incorporated in the lift control circuit whereby the descent of the platform is halted when the bars approach or contact an obstruction. To lower the platform, the lever 8 of a valve 9, located between the lifting ram 7 and reservoir 10, is turned to the broken line position 8<SP>1</SP> against the action of a spring 18, thereby closing a switch 19. Closing of the switch 19 closes the circuit of an electromagnet 15 which pushes out a locking bolt 16 against the action of a spring 17 to hold the lever 8 in the position 8<SP>1</SP>. When the bars 13 engage or approach an obstruction, the switch 14 interrupts the control circuit, the electromagnet 15 is de-energized, the bolt 16 is withdrawn by the spring 17 and the valve 9 is closed by the spring 18. A switch 20 in parallel with switch 14 is mounted on the platform to eliminate the influence of the floor on the bars 13 and is closed on engaging a fixed cam 21 to maintain the electromagnet 15 energized when the switch 14 opens as the platform approaches its lowermost position.
