Filed: 1946-07-22
Abstract: 617,432. Rotary elevators. POWELL, H. C. July 22, 1946, No. 21807. [Class 78 (i)] A spiral staircase or ramp comprises a poweroperated rotor 9 surrounded by a fixed ramp or staircase 1, the rotor carrying means such as helical rail 11 to be manually held by a person walking up so as to propel him upwards. In the Figures, the staircase 1 has steps 3 and fixed balustrades 4 and 6. Person stands on the steps and grasps the rail 11 either directly, or grasps handles which are fixed or slide on the rail, so that he is assisted with an upward pull. There may be several such rails fixed in slots in the rotor, each at a different angle so as to be used at different rotor speeds. An additional ramp 13 may also be provided. Alternatively, the assistance may take the form of an endless moving belt mounted on pulleys in a vertical radial slot in the rotor and such as to be grasped by the hand. The rotor may be in several parts and driven by one or more motors of the type which give increased output with increased load.

Abstract: 980,750. Gas filters. OZONAIR ENGINEERING CO. Ltd. May 30, 1963 [June 8, 1962], No. 22362/62. Heading BIT. [Also in Divisions G3 and H2] A pressure-responsive switch A senses the resistance to air flow through a fabric filtering medium and controls an electric motor 10 to feed clean fabric medium into the filtering apparatus in place of dirty medium. When the pressure in the vicinity of the medium reaches a predetermined value, the switch A is closed to energize thermal resistance wire H. If the switch A is kept closed continuously for one minute due to dust build-up on the fabric, a bimetallic switch K is closed by the element H. The switch K is not closed, however, when the switch A is intermittently operated due to local turbulence. Closure of the bimetallic switch energizes contactor F which connects the motor to the supply. Switch G is opened to de-energize the element H, whilst switch L is closed to place the motor directly under the control of switch A. The motor continues to operate until the switch A opens due to the pressure in the filter returning to a desired value. Switch C allows manual adjustment of the fabric filtering medium, switch D being opened when the supply of clean medium is exhausted. An inching switch E is provided as well as an overload safety switch 25.

To provide a cooling effect for an interconnector between two adjacent flame tubes in a combustion chamber and for the flame tube walls adjacent the interconnector, air is caused to flow through a semi-annular gap formed between the downstream half of each end of the interconnector and the respective flame tube wall, this air then being directed along the inside of the flame tube wall by an outwardly directed flange provided at the downstream side of each end of the interconnector and located within the respective flame tube. An interconnector between two adjacent flame tubes in an annular combustion chamber for use in gas turbine power plants, comprises two crossover tubes 16 (one shown in Fig. 4) connected by a sleeve (not shown). Each crossover tube 16 is welded over its upstream half to its respective flame tube which comprises a number of overlapping rings, e.g. 20, 22 welded together and provided with openings 26 for the admission of air into the flame tube. The downstream half of the crossover tube 16 carries a flange 30 and is spaced from the flame tube wall to provide a passage 32. A semi-cylindrical shield 34 secured to the downstream half of the crossover tube provides two openings facing upstream to receive cooling air which flows around the downstream side of the crossover tube and through the passage 32.
