Abstract: 1,230,896. Refrigerating. TRANE CO. 15 Dec., 1969 [20 Dec., 1968], No. 61002/69. Heading F4H. In an adsorption refrigeration system having a condenser 12, two side-by-side evaporators 14, an adsorber 16 and a two-stage generator 18, 20, the supply of hot fluid, e.g. steam, passing to a heat exchanger 34 mounted in the generator 18 is controlled both on start-up and during continuous operation by a valve 105 according to the load on the system as sensed by a thermostat 82 in contact with the chilled water flow in a conduit 45 from the evaporator, which thermostat operates a time delay means 95. The thermostat 82 activates the time delay means to produce a predetermined changing signal which is relayed to the valve, and the time delay means is initiated only when a predetermined temperature is achieved by the water flow. The control system is pneumatically operated from a source 80. A throttling valve 31 in a by-pass conduit 29 of a cooled heat exchange fluid circuit including heat exchangers 22, 28 in the adsorber 16 and condenser 12 respectively is also responsive to the time delay means in dependence on a signal transmitted from a thermostat 101 sensing the outlet temperature of the cooled heat exchange fluid.

Abstract: 1,251,881. Fuelling reactors. ATOMIC ENERGY OF CANADA Ltd. 14 April, 1969 [15 April 1968], No. 18967/69. Heading G6C.  In the fuelling arrangement disclosed in copending Application 18963/69 in which the head L of a fuelling machine A may pivot through 90 degrees about a horizontal axis so that the snout P may be coupled either to the lower end of a reactor fuel channel D, Fig.. 2, or to the end of a horizontal fuel transfer tube J leading to a fuel shuffling bay H, the machine A may be moved from the fuelling vault B, through a passageway Z in the vault wall normally closed by a door M, and into a maintenance cell F, Fig. 5. The fuelling machine A comprises a carriage 10 having wheels 12 running on rails 13 in the vault B and a trolley 11 running on rails 18 on the carriage. To transfer the machine from the vault B to the cell F, wheels 15 on the carriage 10 are lowered to engage rails 16, wheels 12 are retracted, the door M is displaced horizontally and a shielding gate Y above the door is raised; also, the head L is disposed in the horizontal position and the trolley 11 disposed adjacent a post 21 mounted on one end of the carriage. The several hydraulic motors of the machine A are supplied by cables divided into three seriesconnected spans 22, 23, 30 to permit motion of the machine. Span 22 extends from the machine A to the head 21a of the post 21; span 23 extends from the post to one end of a trailer 24 mounted on rails 25 disposed parallel to the rails 16; and span 30 extends from the other end 38 of the trailer to rollers 31 in the cell F. When the machine A is positioned for movement through the passage Z a pin 28 on the machine enters the open end of a slot 27 formed in a bracket 26 attached to the trailer 24, this slot extending parallel to the rails 13, whereby when the machine enters the cell F it pushes with it the trailer. The trailer 24 comprises a cart 32 having four wheels 33 running on the rails 25 and an extension 34 pivoted to the cart about a horizontal.axis 35, this extension having two wheels 36 running on the rails. The wheels 36 engage a downwardly curved extension 29 of the rails 25 when the trailer enters the cell F thereby causing the extension 34 to pivot downwards so that the trailer 24 requires less space. The shielding gate Y is moved by a cylinder 322 and comprises a horizontal bar 320 connected by bolts 331 to a horizontal slider 330. When the machine A is in the vault B the slider 330 rests on the trailer extension 34 and when the machine is in the cell F the slider rests on the door M.

Abstract: 1,264,696. Film thickness control apparatus. E. I. DU PONT DE NEMOURS & CO. 19 Sept., 1969 [20 Sept., 1968], No. 46241/69. Heading B5B. The thickness uniformity of uniaxially or biaxially stretched thermoplastic polymer films, is controlled by measuring the thickness of each of a plurality of lanes across the film before and after stretching, comparing with a desired standard thickness and adjusting the thickness of pre-stretch lanes accordingly. It is preferred to produce a polyethylene terephthalate film by casting from an extrusion die 11, which has a plurality of adjustment devices 13a, 13b ... (13n), (not shown), on to a quench drum 12 which is internally cooled. The film 10 passes through a heating device 14, which consists of many heating elements arranged parallel to the longitudinal axis of the film, and the film is then heated to its orientation temperature and stretched at 15 and thereafter wound up into roll form 16. A first thickness measuring device 17 is situated between the quench drum 12, and the heater 14, and a second thickness measuring device 21 between the stretching device 15 and the roll 16; each consists of a radiation source 19, 19<SP>1</SP> emitting beta rays, and a detector 20, 21, and powered by motors 18, 22, traverse the width of the film. They each generate electrical signals which are a function of the film thickness, and hence of its mass, at each of a number of preselected points across the width of the film as determined by the action of rotary switches 28, 29. Hence as the film travels through the apparatus, the thickness of a number of hypothetical lanes is monitored. The signals are sent to the computer 26, where the cumulative masses of the film before and after stretching are compared. Adjustments to the pre-stretch thickness are made either by altering the orifice opening 13 to any lane, or by varying the power input to one of the heating elements in 14.

[Also in Division B8] A masted lift truck is provided at each side with an hydraulically operated stabilizing device 12 which is connected to the lift circuit of the mast assembly 8 so as to be brought into engagement with the ground when the fork 11 is raised to a predetermined height. As shown, the fixed mast section 9 is provided with switches 26-28 which are adapted to be actuated by a cam 25 on the movable mast section 10 and which are connected in the electric circuit, Fig. 3 (not shown), controlling the pump motor and electromagnetic valves in the hydraulic circuit, Fig. 2 (not shown). Each device 12 comprises a cylinder 13 containing a piston 15 which is urged upwardly by a spring 18 and which is connected to a cam 22 for actuating switches 23, 24 in the control circuit. On extending the mast assembly, the control circuit, on actuation of the switches 26-28, causes fluid to be directed to the devices 12 which are thereby extended into engagement with the ground. If the devices do not engage the ground, the switches 24 will not be actuated and the control circuit is arranged so that the pump motor will stop and thereby prevent continued extension of the mast assembly. The control circuit may be provided with override switches whereby the devices 12 may be actuated manually or, alternatively, automatically when the load is of more than a predetermined weight, determined by means of a pressuresensitive member.
