Lifts.-An electrically driven staircase passenger lift L travels on one or more rails R, R<1> secured to the walls and is controlled by push buttons 44, 43, 45 at the head and foot of the staircase and on the lift, respectively. The rails, Fig. 3, are channel-shaped and attached to the walls by bolts 13 passed through the wider inner side 11. A platform 22 and seats 23 are hinged to a plate 24 which is attached to a frame 18 having pairs of rollers 29, 31 for engaging the base and sides of the rails. The hoisting cable 32 passes over an idler drum 16 mounted at the top of the rail R', around a pulley 26 driven by an electric motor 41, around sheaves 36, 37, and is anchored to a floor sill 38. A bell-crank ]ever having a pointed end 33 is pivoted to the frame 18 and connected to the cable 32. When the cable breaks, a spring 33<1> pulls the end 33 into engagement with the rail and stops the lift. In a modification, Figs. 5 and 7, the lift runs on a single rail R<11> which rests on the staircase. The lift has a platform 48 for passengers, a platform 49 for luggage, and a back 50. Axles 52 secured to the lift carry rollers 56 which run on the base of the rail and are protected by inward extensions 47 of the sides. The drum 16 is geared to the motor and the cable 32, anchored as before, depends on a single bight and supports a weighted sheave 64. The safety sustaining device acts on the side 46 of the rail. In both constructions the motor is provided with a magnetic brake to prevent movement of the lift when the motor is not working.

Filed: 1963-07-04
Abstract: 1,029,177. Artificial respiration apparatus. AIR-SHIELDS, Inc. July 4, 1963, No. 26536/63. Heading A5T. Artificial respiration apparatus comprises a bellows 9 for connection with the patient, a chamber 8 surrounding the bellows and supplied with gas under pressure under the control of a main valve 25, for effecting inspiration of the patient, a timer mechanism 28, for opening and closing the main valve, and an expiratory gas discharge valve 31 controlled by gas pressure under the control of the main valve so that it opens to permit the patient to exhale but closes during the inspiration part of the cycle. A face mask 5 is supplied with air from the bellows 9 through a conduit 4 in which a humidifying device 6 is arranged. The chamber 8 is supplied with compressed air by a fan 18b operated by a motor 18a through the main valve 25, a conduit 19 and a valve 20. The main valve is opened and closed cyclically by a solenoid under the control of the timer mechanism 28 when the valve 25 is open compressed air is supplied to the chamber 8 for a predetermined period and causes collapse of the bellows 9, air being supplied to the mask 5 through a valve 13 to induce inspiration. When the main valve is closed, air is vented from the chamber 8 through a valve 22 so that the bellows expands and atmospheric air is drawn into it through a filter 15 and a valve 17. While the bellows is expanding the expiratory valve 31 adjacent the mask opens so that the patient exhales. The vent valve 22 of the chamber 8 and the expiratory valve 31 are controlled by pressure chambers 24, 33 connected to the duct 19 downstream of the main valve so that they are closed when the main valve is open. When the main valve is closed, the pressure chambers are vented to atmosphere through the duct 19 and a duct 35 in the main valve. In the event that the patient makes a spontaneous inspirational effort during the expiration phase, pressure is reduced in a conduit 38 between a pressure-responsive device 37 and the patient's supply conduit 4 so that a plunger 40 operates a switch 41 in a lead 42 to the timer mechanism. This triggers the timer mechanism to the inspiration phase so that the main valve opens. Air delivered by the fan 18b passes over the motor 18a to the duct 19 and becomes warm. Some of the warm air is diverted at a point upstream of the main valve and supplied to a chamber 47 beneath the water chamber of the humidifying device 6.

Abstract: 969,581. Sorting eggs. S. SMITH & SONS (ENGLAND) Ltd. June 5, 1963 [July 12, 1962], No. 26889/62. Heading A5K. Fertile and infertile eggs are sorted by investigation of their response to a change in ambient temperature. If eggs are warmed to, for example, 30‹ C. and then allowed to cool to room temperature, such as 20‹ C., fertile eggs return to room temperature more rapidly than inert eggs and may be identified accordingly. In an apparatus, shown schematically, eggs are warmed to 30‹ C. in a chamber 10 and are then withdrawn on trays 11, so that after perhaps ten minutes they reach an infra-red scanner 13 which stores information as to which eggs have the lowest surface temperatures. These, being fertile, are removed by a suction cup sorting head 14, controlled by the scanner and transferred to a conveyer 17 for incubation while the inert eggs are similarly passed to a second conveyer 18.

Abstract: 1,113,112. Machinery guards. MORPHY RICHARDS Ltd. 5 July, 1965 [4 July, 1964], No. 27680/64. Heading F2J. In the raised position of a vertically-movable guard 5, an arresting block 17 is located between pressing elements 1, 2 of a press brake and actuation of the power control mechanism is prevented by a rod 12 which blocks movement of a rod 24 connected to a starting pedal 3. A rod 10 attached to the guard 5 blocks movement of the rod 12 and thereby prevents removal of the arresting block 17 from its position between the pressing elements 1, 2. When the guard 5 is moved manually downwardly, a shoe 13, Fig. 3 (not shown), attached thereto actuates pneumatic or hydraulic means 14, 15 which causes the block 17 to be withdrawn from its position between the pressing elements 1, 2 and causes the rod 12 to enter a slot 11 in the guard 5, thereby locking the guard in its guarding position. A hole 23 in rod 12 is aligned with rod 24 thereby allowing depression of pedal 3 to actuate the ram 1 of the press. On completion of the press cycle, the guard 5 may be raised slightly, the extent of slot 11, so that shoe 13 disengages the control means 14 which then causes movement of the blook 17 forwardly to its position between the pressing elements 1, 2 and causes movement of the rod 12 rearwardly to unlock the guard 5 so that it may be moved upwardly.
