Filed: 1953-07-15
Abstract: 763,342. Door-operating apparatus. BEEDELL, G. M. July 15, 1954 [July 15, 1953], No. 19646/53. Drawings to Specification. Class 65 (1). Garage doors operated by a reversible electric motor are controlled by a switch actuated by movement of a pivoted magnet in response to magnetic induction from a vehicle near the door, for example by a magnet on the vehicle. Momentary closure of the magnetic switch, or of a manual switch inside the garage (which may be supplemented by a second magnetic switch inside the garage) causes energization of a relay whereby the motor is caused to run until a reversing switch is actuated by a sliding rod with abutments engaged by the door near the ends of its travel, the relay being de-energized by the actuation of the reversing switch. In the arrangement described the door is mounted to move upwards and inwards, being connected to a nut on a horizontal screwed shaft arranged perpendicular to the doorway under the roof and driven by the motor. A lamp may be lit when the reversing switch is in one position.

Abstract: Magnesium chloride is produced by reacting with chlorine a magnesium-containing mixture, the said mixture being formed by making a uniform suspension of finely-divided magnesium oxide in one or more liquid hydrocarbons and destructively distilling the suspension while agitating (see Group II).  The said mixture is reacted with chlorine gas at an elevated temperature, the magnesium chloride formed being drawn off and recovered.ALSO:A process for the production of magnesium-containing mixtures which comprises substantially uniformly admixing finely-divided magnesium oxide with one or more liquid hydrocarbons and subjecting the mixture, while it is maintained as a substantially uniform mixture by agitation or circulation, to destructive distillation to form a carbonised or coked mass having magnesium oxide dispersed therethrough, preferably without attaining conditions under which magnesium oxide is reduced.  Finely-divided coking coal or high melting-point pitch may be included in the mixture with a heavy liquid hydrocarbon.  The mixture may be initially heated with agitation, the completion of destructive distillation being performed without agitation.  The coked mass may be mixed with a further quantity of magnesium oxide and a liquid, liquefiable, or thermoplastic carbonaceous agent, this second mixture being coked, or the said coked mass may be mixed with a binder and heated to coke the binder.  Destructive distillation may take place in an inert gas and the products of distillation may be condensed and recovered.  The coked mixture may be used in the production of magnesium chloride (see Group III).

Abstract: 840,375. Flushing cisterns. SUAREZ, P. S. July 4, 1956 [Jan. 12, 1956], No. 20696/56. Class 26. A pneumaticallycontrolled syphon flushing system comprises two inverted- U syphon tubes 1, 2 and 3, 4 leading to the flushing pipe RE, a U-tube AB connecting the upper ends of the parts 3 and 4, and an inverted pressureequalising U-tube RR, between the top of the second syphon tube and a point m near the bottom of the flushing cistern. Intermittent action due to continuous inflow of water into the cistern will first be described ; for this the bulb P is not necessary. After the previous flush, water will remain in the bend 7, and also at the bottom of AB so that rising water in limb 1 forces water up limb B and also spills into limb 2 until water in the bend 7 rising up limb 3 starts to spill into limb 4. At this point water will also be expelled at X from AB to aid in priming the syphon, which empties the cistern until air entering at m interrupts the action; syphon tube SS, then emptying water from the bend 7 until only the amount shown remains. For controlled flushing, a float-operated valve cuts off the water inlet just before water begins to spill over into limb 4, and syphonic action can then be started by compressing bulb P and thus ejecting water at X.
