Abstract: 1,051,436. Retarding action of switches. W. ZINDLER. July 8, 1964 [July 19, 1963], No. 28187/64. Heading H2B. The time delay between operations of a switch 64 is adjustable by varying the length of a track down which a ball 58 has to roll. Depression of a handle 39 moves a cranked rod 45 along guideway 46 to engage the hooked end 55 of plunger 50 and retracts the plunger against spring 52. When the rod 45 is lifted by the portion 47 of the guideway it releases plunger 50 to impinge on a ball 58 which leaves the forked end 21 of a lever 60 and hits a surface 69 and then rolls successively down inclined flanges 10, 29, 11, 30 and 12, finally returning down the lever 60 to its initial position shown. When the ball 58 leaves the fork 21 a snap-action switch 64 is able to pivot lever 60 and its contacts are operated; when the ball returns it presses lever 60 down and restores the switch 64. The inclined flanges 10, 11 and 12 and vertical flanges 14, 22 and 23 are fixed on the back wall 5 of the housing (Fig. 2, not shown), whilst inclined flanges 29, 30 and vertical flanges 15 and 16 are carried on a cover 28 which is slidable by rotation of a calibrated knob 4 acting on a rack 33, thereby altering the length of the return path of the ball 58 and thus the delay time before switch 64 restores.

Abstract: 1,051,520. Refrigerating. WORTHINGTON CORPORATION. July 27, 1965, No. 31965/65. Heading F4H. In an absorption refrigeration system utilizing lithium bromide solution as absorbed and water as refrigerant and in which weak solution from the absorber 10 is mixed with strong solution from the generator 13 for return to the absorber, the flow of weak solution for mixing is controlled in accordance with the load on the evaporator 11 of the system. As illustrated, a pump 29 draws weak solution through a line 52 from a sump 22 of the absorber for return to the absorber spray 26. A line 59 in the pumping circuit includes an ejector 16 which draws stronger solution from a receiver 39 which is fed with strong solution from the generator and with weak solution from a line 47 leading from the absorber sump. A valve 48 in line 47 is controlled by temperature sensed in the fluid line 81 cooled by the evaporator. A further line 23 from the absorber sump 22 passes weak solution to the generator via a heat exchanger 14 in contact with the strong solution flow from the generator to the ejector 16. A partition 41 divides the receiver 39 to ensure that the heat exchanger 14 remains full of concentrated solution at all times. The generator is steam heated by a heat exchanger 67 in series with a supplementary heat exchanger 72. Coils 27 and 19 in the absorber and condenser are connected in a cooling tower circuit, a valve 65 controlling the flow of water in the circuit according to the temperature of refrigerant leaving the condenser or according to ambient conditions. In a modification, Fig. 2 (not shown), lines 23 and 47 from the sump 22 are replaced by a single line 40 having a three-way valve 76 controlling flow from line 40 to the receiver 39 and to the heat exchanger 14. The valve 76 is controlled manually or automatically according to temperature in line 81.

Abstract: 1,051,954. Fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 28, 1965 [April 8. 1964]. No. 3735/65. Heading G6C. A ceramic nuclear fuel material is compacted within a container by subjecting a selected size range fraction thereof to axial vibration within the container until a close-packed configuration is attained and then introducing a smaller size range fraction into this configuration while simultaneously holding it in place by pressure and subjecting it to combined axial and radial vibration. A suitable vibratory compaction apparatus comprises a conventional vibrator 11 to which is firmly attached a holder 12 which securely grips the bottom of a container 13. A " rattle cage " 14 consisting of upright support members 16, a bottom collar 17, an upper collar 18 and intermediate collars 19 rests on the vibrator 11 surrounding the container 13. The particles 21 of largest diameter are put into a close-packed configuration within the container 13 using the vibrator 11 without the rattle cage 14 and then a pressure thimble 24 is lowered into the container 13 and clamped in position when in firm contact with the particles 21 so as to prevent them from moving out of their closepacked configuration. The bottom 26 of the thimble 24 has apertures 27 of such a size as to allow particles 21a of smaller diameter to pass through but not the particles 21. The smaller particles 21a are added in increments and dispersed throughout the void space between the particles 21, the axial motion imparted to the container 13 by the vibrator 11 being supplemented by radial motion as the rattle cage 14 moves back and forth against the container, with the result that agglomerations of the particles 21a are broken up and bridging generally is prevented. At the same time, pressure from the thimble 24 keeps the particles 21 in place so that they cannot rise and stratify. If it is desired to add particles of still smaller diameter, the thimble 24 is replaced by one with smaller perforations which will permit passage of the latter particles but not of those already in the container and the packing operation as for the particles 21a is repeated.

[Also in Divisions F2 and G3] A valve for use with ball throwing mechanism comprises a piston 59 spring-loaded to a closed position to block communication between an inlet 16 and an outlet 18 and formed with a groove 77 to communicate the inlet pressure to both ends of the piston. A discharge conduit 32 leads to a pilot valve for releasing the pressure from above the piston to open the valve. The pilot valve is operated by the pressure of fluid in the conduit 32 or by a solenoid controlled by a clock. A diaphragm 58 is connected to the bottom of the piston by a rod 56 which has a passage 75 therein to interconnect both sides of the diaphragm. In operation after the pressure below the piston is released to the outlet the pressure below the diaphragm ensures that the piston moves to its upper most position. The inlet and out-let openings 51 are rectangular. The diaphragm and groove 77 may be dispensed with and the piston is then made a loose fit. In use the valve is connected between a fluid pressure reservoir 14 and a ball throwing mechanism 27 having a pivoted arm 28 holding ball 38, which arm is actuated on opening the valve 12 to release pressure fluid to the mechanism 27. The pilot valve 30 is mounted in the mechanism 27 and has an adjusting lever 33 for altering the intervals between valve actuation. The intervals may also be adjusted by operation of the supply valve 24 for the reservoir 14.

Abstract: 1,229,431. Lap forming apparatus. OWENSCORNING FIBERGLAS CORP. 25 June, 1968 [25 July, 1967], No. 30296/68. Heading D1N. [Also in Division G3] In a system in which a glass fibre mat is made by depositing fibres from a heated fibreproducing bushing on to a conveyor, the speed of the conveyor is automatically varied in dependence on the amount of heat supplied to maintain the bushing at a desired temperature so as to produce a mat having a desired weight per unit area. In Fig. 1, molten glass is supplied from a furnace 10 to an electrically heated bushing 11 from which it issues through. orifices 12 and is formed into fibres by gas or steam jets at 13. The fibres fall within a hood 30 having adjustable side walls, and binder or other material such as oil is added through dispensers such as 50. The mixture forms a mass on a conveyor belt 41 to which it is held by suction. The mat is then transported by a series of conveyors past a compression device 66, an electric heater 74, an edge trimmer 80 to a cropper 85 which cuts it into lengths for packaging. A master controller, which may be operated manually or from a tape reader, sets hood width, binder feed rate, conveyor speed, oven conditions, trimmer position and cropping time to values which are automatically maintained by closed loop control systems. The power supplied to the heater of bushing 11 is automatically controlled to maintain a desired temperature and variations of this power, being representative of changes in the rate of fibre production, are applied to vary the datum of the systems controlling binder feed rate, conveyor speed, oven conditions and cropping. An X- ray gauge 60, responsive to mat density also automatically modifies these controls in dependence on variations of mat density or operates an alarm if the variations exceed a predetermined magnitude. Additional correspondence control linkages are also provided between certain of the controls.

Abstract: 1,232,232. Stabilizing convertiplane rotor systems. TEXTRON Inc. 8 May, 1968 [9 May, 1967], No. 21705/68. Heading B7W. A convertiplane rotor comprises a main mast 37 rotably mounted at one end on the airframe and having pivotally connected to its other end a stub mast 42 carrying the rotor blades 41, and cyclical variable pitch linkages 53, 54, 56 connected from pitch horns 58 of each rotor to a swashplate 40 operable when the stub mast pivots with respect to the main mast to vary the pitch of the blades to oppose the instability produced by that angular displacement, the rotation of the joints between the pitch horns and links defining a control plane rearward of the pivotal connection between the main and stub masts. The stub mast 42 is a tapered hollow body pivotally connected to the main mast 37 at its reduced diameter through splines 46, 44. Its large diameter end is inward and carries a hub 61 on which the rotors 41 are mounted. The stub mast is driven at the same speed as the main mast but drives the hub 61 at a reduced speed through sun and planet gears 63, 64. A central control tube 48 extends through and beyond the end of main mast 37 and carries a rotatably mounted collective head on which are pivotally mounted walking beams 53 (one to each blade 41). One end of beam 53 is connected to a blade pitch horn 58 and the other end to a swash plate 40. Thus angular displacement between stub mast and main mast will cause a similar displacement between swash plate 40 and plane of rotation of pitch horns 58 with a consequential change in pitch of the rotor blades. In an alternative embodiment (Fig. 4) a rotor hub 79 is driven by a gimbal 82 and pillow block housing 84. The housing 84 which forms the stub mast is rotatably connected to a main mast 83 through a universal joint 92. Pivotal movement is provided between stub mast and main mast by the universal joint 92. This comprises an inner bowl 93 connected to the main mast movable over a seating ring 103 on an outer bowl 99 connected to the stub mast. Cyclical pitch change of the rotor blades is effected through a swash plate 106, tube 107, walking beams 108, 114 and tube 116. The change in pitch produces forces opposite to those which caused the angular displacement between stub mast and main mast.
