Title: Improvements in delivery and counting apparatus for newspaper folding machines
IPC: B65H33/08
Filed: 1934-05-08
Abstract: 435,333. Paper folding and delivery apparatus. COSSAR, T., 4A, Ripon Road, Harrogate, Yorkshire. May 8, 1934, No. 13834. [Class 100 (i)] in a delivery and counting apparatus of the type in which papers are piled in succession on a travelling delivery apron or the like and jogging mechanism operates to control the piling of the papers, whereby these are arranged on the apron in defined bundles each containing a definite number of papers, the jogging mechanism includes an oscillating jogging member which operates in repeating cycles, each cycle comprising a series of oscillations of increasing amplitude. Printed webs 1 pass between rotary cutters 2 which sever the webs into sheets which pass down an inclined path 3 to a reciprocating folding blade 4 and a pair of inclined rotating rollers 5 which give the sheets a first fold. A second fold at right angles to the first told is obtained by a second pair of inclined rollers 6 and a further reciprocating folding blade, after which the sheets are ejected on to a delivery apron comprising a set of endless bands 7 passing round spaced pulleys 8 at one end and an adjustable guide roller 9 at the other end of the apron. To control the folded papers 12 as they are delivered and to support the leading edges until they are completely ejected from the folding rollers 6, a rod 23 is caused to oscillate transversely of the line of travel of the folded papers and to swing in underneath the folded paper 12 as it is ejected, when the rod 23 swings outwardly and the paper 12 falls on to the band between side guides 24. The delivery apron is moved on step by step as each folded paper is delivered by a ratchet wheel 26 mounted on the shaft 10 carrying the pulleys 8, which is rotated by a pawl 33 mounted on a rock lever 27 actuated from the rock shaft 14 which controls the oscillations of the rod 23. A further rock shaft 34 carries jogging members 42 which pass between paper-supporting members 13 and are adapted to be moved forward on the downward movement of the rock lever 27 which engages a roller 39 mounted on a link 37 connected to the rock shaft 34, the return movement being effected by a spring 40. The arcuate surface 28 of the lever 27 is as arranged that the jogging members return to a substantially invariable position. The angular travel of the jogging members 42 increases in amplitude in repeating cycles whereby the delivered papers are separated into batches containing a predetermined number of papers, and this is effected by one or more spiral shaped cam surfaces 30 on a cam 29 carried by the shaft 10 and engaged by the roller 39 carried by the link 37. The roller is pressed against the cam by a spring 41, and as the cam rotates, the link is moved outwardly resulting in a gradually increasing movement of the members 42 until the roller passes off the high part and engages the low part of the cam, whereupon the movement of the members 42 becomes a minimum and a second cycle commences, resulting in the papers being delivered in batches as shown.

Abstract: 734,685. Stuffing-box substitutes; turbines. BRISTOL AEROPLANE CO., Ltd. May 27, 1953 [June 3, 1952], No. 13996/52. Classes 110 (3) and 122 (5). A sealing device for use in power machines operated by compressible fluid pressure comprises maintaining between zero and a maximum dimension a peripheral gap located between two members movable towards and away from one another and separating a zone of high pressure P (high) from a zone of low pressure P (low) by providing (a) a pair of mutually opposed peripheral surfaces on the members defining the gap which converges from the high pressure to the low pressure zone; (b) means for urging the members together with a force which is less than P (high) times the projected area of the opposed surfaces in a direction normal to the force and is not less than the force exerted on the projected area when the gap is open to its maximum dimension ; and (c) means to control the force as a function of P (high) such that the force does not increase due to closure of the gap. An annular piston 4 slidably supported on piston rings 36 in a cylinder 35 formed in a compressor housing 31 has a face 7 separated from an opposed face 6 on the compressor rotor 30 by a gap 8 converging from the higher pressure P (high) to the lower pressure P (low) side of the piston 4 which is urged toward the rotor 30 by fluid admitted from the high-pressure side to the cylinder 35 through a passage 11 and discharged therefrom to the low-pressure side through a nozzle 12, preferably " choked " so that the pressure behind the piston is independent of P (low). The piston 4 is urged away from the rotor 30 by a force equal to the annular area of the face 7 multiplied by the mean pressure in the gap 8 which pressure increases or decreases as the gap decreases or increases ; the gap is thus automatically maintained between predetermined limits. In a modification the cylinder 35 is replaced by a flexible bellows secured to the piston and the housing and the pressure may be admitted to the interior of the bellows from the high-pressure side P (high) through a conduit having its inlet end close to the face 6 to form an entry port therewith which decreases in size as the gap 8 diminishes and thereby produces a fall in the pressure in the bellows. In a further modification the cylinder 35 is formed by a pair of concentric flexible rings attached to the housing and in sliding contact with the piston 4 and having axial slots therein to act as inlet and discharge passages to the space behind the piston.

[Class 51 (ii)] An atmosphere gas, more particularly adapted for use in the bright annealing of copper, is produced by burning gas or oil with just insufficient air to convert the whole of the sulphur impurities in the fuel into sulphur dioxide, and passing the products of combustion in contact with a reagent, such as iron oxide or heated copper, which will remove sulphuretted hydrogen and carbon bisulphide without, at the same time, removing any substantial quantity of sulphur dioxide. Preferably the products are cooled after combustion and then passed in succession through purifiers containing the oxide and heated copper turnings. The second purifier may be heated from the chamber in which the fuel is burnt. The presence of oxygen and sulphuretted hydrogen in the gas may be indicated, either during manufacture or in use, by passing the gas through an electrically heated tube containing bright copper.
