Title: Air conditioning apparatus
IPC: F24F3/052
Filed: 1955-03-16
Abstract: 787,568. Ventilating. ROBERTSON THAIN, Ltd. (Robertson Co., H. H.). March 16 1955, No. 30473/56. Divided out of 787,565. Class 137 In an air-conditioning or ventilating plant wherein condits 97, 98 convey conditioned air to an outlet box 131 from which the mixture is discharged into the room, the dampers 125 controlling the admission from the conduits are automatically operated by a piston-and-cylinder mechanism 230 which is responsive to thermostatic means. These means may be selectively set so as to be responsive to one or other of two different sets of conditions for example winter and summer operation. In winter when hot air is being supplied by one conduit and cold by the other the thermostatically controlled mechanism 230 imparts opposed movements to the damper i.e. one damperopens as the other closes; in summer when both conduits are supplying cold air both dampers can be moved by the control into substantially open position. This enables the capacity of the cool air supply to be increased without increasing the size of the ducts. Specification 420,062 also is referred to.

Abstract: 735,291. Side bolsters for wagons. GENERAL ELECTRIC CO., Ltd., and MITCHELL, K. J. Dec. 17, 1952 [Dec. 31, 1951], No. 30487/51. Class 78 (4). The height of the side bolster in a wagon tippler may be adjusted continuously or in steps to accommodate wagons of different patterns. As illustrated, the bolster is supported by beams 24 which are supported at their opposite ends by lead-screws 25 which can be driven by electric motors 26 to adjust their height. The side bolster has a resilient cushion 20 mounted on a channel 21 which is pivoted at 22 to brackets 23 supported by the beams so that the bolster is self-aligning. Counterweights 36 normally hold the bolster in the position illustrated. The tippler illustrated is driven by ropes 27 which extend from drums 28 driven by an electric motor around curved surfaces 17 on the cage. Initially the cage turns about an axis 31 during which motion surfaces 19 on the track portion 12 engage rollers 14 to allow the track portion 12 to tilt about an axis 13 to bring the wagon 11 into contact with the side bolster. The top of the wagon subsequently engages rubber-covered self-aligning top bolsters 32 carried by arms 33 which then roll along surfaces 34 carrying the wagon and cage with them.

Abstract: 286,578. Igranic Electric Co., Ltd., and Hopwood, H. Nov. 15, 1927. Thermionic amplifiers and detectors. - The degree of magnetic coupling between fixed coils r, g in the plate and grid circuits of an amplifier v is controlled by means of a three-plate condenser c<1>, c<2>, c<3> in such a way as not to affect the initial tuning of the grid circuit. The condenser plates c<3> moves relatively to the fixed plates c<1>, c<2> in such a way that as the overlap between c<2> and c<1> increases that between c<3> and c<2> decreases and vice versa. The overall capacity between the plates therefore remains constant, though the amount of current flowing through the coil r varies in accordance with the overlap between the plates c<2>, c<3>. The shunt capacity between plate and filament serves to byepass high-frequency currents from the lowfrequency coupling-transformer. The coil r may be an extension of the grid coil g.

Abstract: 845,523. Recording-apparatus. RAYTHEON MANUFACTURING CO. Oct. 9, 1956 [Oct. 17, 1955], No. 30799/56. Class 106 (4). [Also in Group XVI] Recording apparatus comprises a recording paper 50 advanced uniformly in one direction with a stylus 42 moving transversely in wiping contact therewith, a driving roller 30 and a removable drive reel mechanism 20 having a spindle 66 supporting a roll 51 of paper, the apparatus having a pair of plates 21, 22 with slots 91, 92 for guiding the paper along a circular path into rocking engagement with the stylus 42, whereby the record paper is prevented from causing damage to the stylus during rapid insertion into or removal from the recording apparatus. To recharge the apparatus with paper, the mechanism 20 is removed and old and new rolls are interchanged on the spindle 66, after pushing aside a spring 71, which retains the roll against a plate 74 and acts as a friction drag to keep the paper taut when being drawn off the roll 51 by the driving-roller 30 during operation. Paper 50 from the new roll 51 is arranged round a guide-roller 64, over a platen 60 and between L-shaped edge guides each side of a top-plate. The spindle 66, roller 64, platen 60, an idler roller 68 and the top plate are all carried between two side-plates 61, 62 from which projects a hinge-pin 69. When replacing the mechanism 20 in the apparatus, the slots 91, 92 in the side-plates 21, 22 guide the hinge-pin 69 into opposed holes and the need to tilt the mechanism to avoid the platen 60 fouling the driving-roller 30 safeguards the stylus 42, with which contact is made gently by rocking the mechanism 20 to raise the idler roller 68 and platen 60, with the paper 50 intervening, into engagement with the driving-roller 30 and stylus 42, respectively, in which position the mechanism is retained by a locking-device 89, 120. The mechanism 20 is so balanced that when the lock 89, 120 is released the platen 60 falls away from the stylus 42, which is prevented from falling too by a cross-bar 27. An unevenly wound roll 51 is maintained in alignment with the rollers 30, 68 by guide-plates 95, 96 mounted on the plates 61, 62 by screw pivots 97, 98 and held in position by spring-mounted pins entering holes in the plates.

Abstract: 877,488. Plying and twisting strands. DEERING MILLIKEN RESEARCH CORPORATION. Oct. 3, 1957 [Oct. 3, 1956], No. 31023/57. Class 120(2) Cord-forming and winding apparatus comprises rotatable means e.g. 21 for plying at least two strands i.e. filaments, assemblages of filaments or fibres, or previously-twisted singles or multi ply yarns, by causing part of the path of a first strand to rotate around a source of a second strand, twister means 101 including a cord-twisting and winding-guide rotatable around a spindle, intermediate cord feeding means 45, and driving-means synchronously connected to all three means to form a cord having a selected constant singles twist and cord twist. In a form where two strands are plied, the plying means is of the kind described in Specification 835,411, wherein a strand A after passing through a driven spindle 15 balloons about a strand B drawn from a stationary package, the strands being wrapped around delivery-equalizing capstans 23, 25. The intermediate feed-means comprises driven canted rollers 47 around which the cord is wrapped. The cord passes via a pivoted guide 97 to an aperture in a ring 103 driven to rotate about a spindle 114 and traversed by a rail 107 moving on guides 108 under the influence of a rotated cam 143. The parts may be driven by a motor M. The spindle 15 is driven through a timing-belt 77, the feed-means 45 by a timing belt 49, a shaft 50, a change-gear 51, bevels 71 and 73, a shaft 74 and a timing-belt 75, and the ring is driven by a timing-gear 76 on shaft 74, a timing-belt 80, a shaft 82, a change-gear 81, a toothed drum 93 and a timing-belt 95. The rotation of the spindle 114 under the pull of the cord as it is being wound is resisted by a brake-drum having a strap 127 with its ends secured to a drum 129 on an adjustment shaft 131 connected to the drum by a torsion-spring. Twists are imparted at the plying-point to the cord and at 103 both to the cord and its component strands; these may be varied by changing the components of the gears at 51, 81. At 51, gears 55, 53 are exchanged for others when a large change of twist is required; gear 59 is changed when fine adjustment only is needed, and idler 61 is removed when Z-twist is required instead of S-twist. Similar changes can be made at 81 whereby twist may be added to or subtracted from the ply and the individual strands. The twist-winding means 101 may be disposed vertically above the plying-means and vice-versa, and the axis of the two may be in the same vertical plane. Shaft 82 may be driven off shaft 50 and separate synchronously-driven motors may be provided for the plying, feeding and twisting-winding means. Specification 877,489 also is referred to.
