Title: Manipulation of objects
IPC: B65B21/20
Filed: 1974-06-14
Abstract: 1462677 Variable spacing of article engaging devices; crating and uncrating SOC GENERALE POUR L'EMBALLAGE 14 June 1974 [15 June 1973 6 June 1974] 26421/74 Headings B8H and B8C A article engaging apparatus for transferring and varying the spacing of a plurality of articles comprises a chassis 1 slidably supported on a vertically displacable device 3. A plurality of load engaging devices 4a-4e, such as grippers, inflatable bulbs or suction heads, are slidably mounted on sliders 16 with springs 5 between adjacent load engaging devices on the same slider and aligned load engaging devices on different sliders are interconnected by a respective bar 15. A pneumatic actuator 6 is connected between the bars 15 interconnecting the load engaging devices 4a and 4e to vary the spacing therebetween, with the springs 5 enensuring equal spacing of the intermediate load engaging devices 4b-4d. The bar 15 of the load engaging devices 4a engages a stop 7 to fix the said load engaging devices relative to the chassis and the bar 15 associated with the load engaging devices 4e are engaged by a stop 18 which allows movement of the bar in one direction but not in the opposite direction whereby to maintain the springs 5 under tension. In an alternative embodiment Fig. 7 (not shown) the sliders (16) are also movable relative to one another under the action of a pneumatic actuator (6a) and have springs (5a) therebetween and are engaged by stops (7a), (18a) as in the first described embodiment. In use articles, such as bottles are advanced along a conveyer 8 into engagement with an abutment frame (10), Fig. 3, 5 (not shown) to stop the articles in aligned files with a spacing (14) or in staggered files with a spacing (14). The chassis is then positioned above the articles and the fixed load engaging device aligned with an article. The remaining load engaging devices are then aligned with the other articles by suitable operation of the actuator 6 or actuators (6), (6a) and then the chassis is lowered for the devices 4 to engage the articles. The chassis is then raised and the actuator(s) operated to adjust the spacing of the articles, such as, into engagement with each other, prior to the chassis being lowered to deposit the articles on a pallet or in a crate. The apparatus may be used to transfer the articles from the pallet &c. to the conveyer.

Title: Improvements in forced flow, once-through tubulous vapour generating and vapour heating units and to a method of operation thereof
IPC: F22B29/10
Filed: 1953-09-30
Abstract: 744,797. Furnaces. BEUTHNER, F. Sept. 29, 1954 [Sept. 30, 1953], No. 26848/53. Class 51 (1). [Also in Group XIII] A forced flow, once through steam boiler comprises two cyclone furnaces 1 and 2 (not shown) which discharge through the front wall 3 of the unit into a secondary furnace chamber 4 when combustion gases pass through a tube screen 28 into a radiation chamber 5 from the top of which they flow through a lateral pass 6 locating a secondary, superheater 65 and a secondary reheater 76. The gases then flow downwardly in a pass 7, the upper part of which is divided into three parallel passes, the side passes 9 each locating the horizontal limb of a primary superheater 69 having vertical limbs extending across the outlet from pass 6 and banks of tubes 68 in which the transition zone is located, whilst the central pass 8 locates primary reheater tube banks 72, 74. Dampers 10, 11 are provided at the pass outlets for the control of gas flow therethrough. Below the dampers the gases pass through high temperature air heaters 84 and economizers 85 into a turning space 13 when they flow upwardly and downwardly in passes 14, 15 locating a low temperature economizer 86 and air heater sections 87. Cooled flue gas is withdrawn from a channel 89 between economizer sections 85 by a fan 88 which delivers the gases to the lower part of chamber 5 through an aperture 90 in the rear wall 42 thereof. The quantity of gases recirculated is controlled by dampers and/or by fan speed regulation. The cyclone furnaces and the walls, floor and roof of the secondary furnace, the radiation chamber and lateral pass are lined with steam generating and superheating tubes, which with the economisers, transition section tubes 68 and primary and secondary superheaters 69, 65 are connected to provide two parallel throughflow circuits for the working medium, the heating surfaces being so arranged, Fig. 7 (not shown), that should the cyclone furnaces be unequally operated, the two circuits will still receive equal amounts of heat. In each circuit, on the downstream side of the transition tubes 68, are disposed cyclone separators 103, for example as described on Specification 746,495, [Group II], the separators, which are dry in normal operation, being provided to remove salts-contaminated water when tubes 68 are being flushed. Spray type attemperators are provided in each circuit on the upstream side of superheaters 69, 65 to provide, a quick acting control of superheat on change of load, &c. The superheated steam pressure and temperature are regulated automatically by adjusting, the flow of water through the circuits and the rate of firing, while the reheated steam temperature is controlled by regulation of dampers 10, 11 and by regulating the quantity of gas recirculated these latter controls also being used to ensure that the transition zone remains within the tube banks 68 where suitable temperature conditions prevail irrespective of load variations on the unit.

Abstract: 695,975. Pneumatic conveyers. BABCOCK & WILCOX, Ltd. Nov. 1, 1951. [Nov. 6, 1950] No. 27044/50. Class 78 (i). In a pulverized fuel firing system with distribution means for supplying different burners from a common conduit, the distribution is controlled by adjustable deflectors which project a limited distance across the stream of fuel and air. The deflectors 18, 19, 20, Fig. 1, are located in an elbow 8, Fig. 2, connecting a supply pipe 2 to branch pipes 5, 6, 7 leading to the burners. The deflectors are mounted on a disc 17 which is rotatably mounted in a wear plate 12 secured to a cover plate 13 closing an opening in the elbow. A bolt 22 welded to the disc 17 at 26 is passed through the plate 13 and a lock nut 24 and is turned to adjust the position of the deflectors by applying a key to the squared end 25. If, e.g. the supply of fuel to the branch 5 is greater than that to the branch 7, the supply is equalised by turning the disc to the position shown in Fig. 4 in which the deflectors are inclined towards the branch 7.

Abstract: 655,228. Pantographic apparatus. NAPIER & SON, Ltd., D. Oct. 21, 1948, No. 27373. [Class 97 (iii)] Optical-projection graticule gauges, images of which are to be projected on to a screen for comparison with the form of the article to be gauged are made by preparing a master drawing of substantially larger scale than that of the graticule to be produced and reproducing this drawing to the correct scale in the form of a scratched line constituting the graticule upon the surface of a projection slide of hard transparent material by means of a pantographic apparatus whose follower is in the form of a stylus capable of scratching a fine line on the transparent material of the slide. As shown, the apparatus comprises a base B having mounted therein an outer boss C<SP>1</SP> carrying a radial arm C<SP>2</SP>. Mounted within an eccentric bore in the boss C<SP>1</SP> is an inner boss D provided with a radial arm D<SP>2</SP>. An eccentric bore D3 whose axis is displaced from the axis of the inner boss D by the same distance as the axis of the outer boss D is displaced from the axis of the outer boss C<SP>1</SP> is formed in the inner boss D and has mounted therein a solenoid through which passes a stylus H. A bar E carrying at its outer end E<SP>2</SP> a tracing point is pivoted to the outer end of the arm C<SP>2</SP> and a link F connects an intermediate point of the arm E with the outer end of the arm D<SP>2</SP>. Energizing the solenoid causes the stylus point to be brought to bear with the desired pressure on the slide on which the graticule is to be traced. When tracing on glass slides a diamond stylus point is used. Alternatively the solenoid may be connected to lift the stylus from the slide in which case tracing contact is maintained by the weight of the stylus.
