Title: Improvements in or relating to a feeding machine for letters or like mail pieces
IPC: B65H3/52
Filed: 1956-03-26
Abstract: 787,495. Feeding sheets. NAAMLOOZE VENNOOTSCHAP TECHNISCHE MAATSCHAPPIJ MARCHAND-ANDRIESSEN. March 26, 1956 [April 5, 1955], No. 9373/56. Class 100(1) Apparatus for separating and feeding letters, postcards &c. from a stack comprises a vertical wall 56 against which a stack 1a of letters 1 is urged by a spring 3, the stack being supported by a horizontal disc 4 which is rotatable to urge the leading edges of the letters 1 against the wall 56. The disc 4 and a friction-feed wheel 5 are secured to a driven shaft 41, the wheel 5 protruding through a slot in the wall 56 to engage the letters 1. Assuming that two superposed letters are separated together from the stack by the wheel 5, their front edges abut the point of contact between a reversely-driven roller 13 and a co-operating idler roller 6, and are both thus held back temporarily. When, however, a cam surface 18, on a shaft 40 which is driven faster than the shaft 39 of the roller 13, engages the top letter and the roller 6 is raised simultaneously from the roller 13, the top letter is fed into the bight of feed rollers 19, 20 which convey it away, and the other letter remains so that it can be fed in the next cycle. The roller 13 comprises two operative disc-like surfaces, one co-operating with the roller 6, and the other, which is of smaller diameter, cooperating with the rotating cam 18. The roller 6 is on a lever 7 pivoted at 8, and is actuated by a cam 10 on the shaft 40. A motor drives a .system of gearing connected with the shafts 39, 40, 41, and also the shafts 38 and 37 of feed rollers 20 and 22, respectively. The shafts 37, 38 are flexibly mounted to allow for movement of the rollers 22, 20 to accommodate different thicknesses of letters &c. 1. A sheet-guide 31, pivoted at 32, extends between the cam 18 and roller 13, and is slotted to allow the two operative surfaces of the roller 13 to protrude therethrough. The other end of the guide is anchored to a rod 57 which is adjustably slidable in a sleeve 58. The guide 31 can also be adjusted by a screw 36 mounted on an abutment secured to the guide.

Title: Improvements in or relating to the combustion of divided fuel in a cyclone furnace
IPC: F23C3/00
Filed: 1955-04-01
Abstract: 768,970. Pulverized fuel fired furnaces. BABCOCK & WILCOX, Ltd. April 1, 1955 [April 3, 1954], No. 9585/55. Class 51 (1). A low volatile fuel. such as fly ash is burnt in a cyclone furnace by mixing it with a high volatile fuel before its admission to the furnace. The furnace lay-out shown comprises a pulverized fuel corner-fired steam generator 1 also fired by a cyclone furnace 8. The generator has an ignition table 5. Fly ash separated from the combustion products flowing through the generator passes is stored in a bunker 46, whilst pulverized coal is stored in a bunker 45. Combustion air for the cyclone furnace is forced by a fan 31 through a heater 32 and then through parallel damper-controlled pipes 34, 35, 36, 37 and 71 to the furnace. The supply through pipe 71 passes to secondary air inlets 21, 22, 23A, 24 within the furnace and to the end 85 of the furnace where it is used as combustion air for a gaseous fuel supplied through a damper-controlled pipe 87. In operation of the furnace, the pressure of the air supplied to inlet 24 is greater than the pressure of that supplied to inlet 23A which in turn is greater than that supplied to 22 which is greater than that supplied to 21. This ensures that the whirling gases within the furnace chamber tend to pass to the end 85 of the furnace before passing in whirl formation axially along to the outlet throat 10. Fly ash and coal from their respective bunkers are entrained by the air flowing along pipes 34-37 and mixtures of them are collected in pipes 61, 65, for delivery at inlets 26, 27, 28, 29, 23B, 23C, in the furnace chamber. In operation of the furnace, the percentage of fly ash in the mixture issuing from inlets 29, 23B, 23C, is less than the percentage of fly ash in the mixture issuing from inlets 26, 27, 28, and as the inlets 26 ... 29 are nearer the axis of the furnace chamber than the inlets 23B, 23C, the length of the gaseous path through the furnace chamber to the throat 10 of the smaller percentage fly ash mixture is greater than the gaseous path length of the larger percentage fly ash mixture. Molten slag leaves the furnace chamber through an outlet 11 whilst combustion products pass through the throat 10 into a secondary combustion chamber 12 passing therefrom into the steam generator through a slag screen 14. If necessary an inlet 25 in the furnace chamber, which is normally kept blocked and held in reserve, is caused to issue pulverized coal in a stream of carrier air, the heat of combustion of this fuel keeping the slag in the region of its outlet 11 in a molten state.

Title: Catalyst compositions for fluorocarbon reactions
IPC: C07C17/20
Filed: 1961-03-17
Abstract: A fluorocarbon catalyst is made by treating activated Al2O3 with the vapour of a lower fluorocarbon containing not more than 8 carbon atoms and not more than one hydrogen atom at an elevated temperature and not exceeding 800 DEG C. which is effective to promote the reaction of the fluorocarbon with the alumina causing evolution of carbon oxides (i.e. CO, CO2, COCl2 and/or COClF), and containing the treatment until the evolution of the carbon oxides has substantially ceased. Preferably the activated Al2O3 is essentially unmodified by other materials.  The activated Al2O3 may be dried before treatment with fluorocarbon vapour.  The catalyst may be used for disproportionation and/or rearrangements of fluorocarbon in fixed or fluidized bed operation.  Example E and Examples 24-30 describe the use of a Cr2O3-containing Al2O3 activated catalyst. Example 13 describes the regeneration of spent activated Al2O3 catalysts by oxidation at 300 DEG -400 DEG C.ALSO:Fluorochloroalkanes are disproportionated and/or rearranged by contacting their vapours with an Al2O3 catalyst activated by treatment with the vapour of a fluorocarbon containing not more than 8C and one or no hydrogen atoms, and which may contain chlorine atoms, at an elevated temperature, not exceeding about 800 DEG C., so as to liberate carbon oxides (i.e. CO, CO2, COCl2 and/or COCIF), treatment being continued until evolution of carbon oxides has substantially ceased. Examples of indicated reactions are:- <FORM:0921796/IV(a)/1> When C2Cl6 is produced it may break down to provide C2Cl4 and Cl2. Disproportionations and rearrangements may occur simultaneously and selection of product is determined by catalyst temperature and/or modification of catalyst e.g. by inclusion of a minor proportion of Cr2O3.  Disproportionation occurs between 150 and 600 DEG C. and between 1/10 and 10 atmospheres pressure. Reaction products and unreacted starting materials, leaving the catalyst bed may generally be condensed by cooling and/or compression to form a liquid one phase mixture from which the desired products may be separated by fractional distillation and unreacted material recycled to the catalyst bed.  Examples are given.

Title: Temperature compensated helix resonator
Inventor: FLINK PEKKA TAPANI
IPC: H01P7/00
Filed: 1991-05-03
Abstract: The stop-band and pass-band frequencies of a duplex filter which includes a plurality of helix resonators must not change when the temperature changes. Therefore the resonators used must be temperature compensated. One known method is to injection-mold plastic bonds (3, 4) to the cover (2) of the resonator shield in such a way that the last turns of the helical coil (4) of the resonator are inside the bond (3, 4). Through a suitable selection of the bonding material it is possible in part to compensate for changes in the distance between the open end of the resonator coil and the cover of the shield and for changes in the pitch of the turns of the conductor (4) wound into a helical coil and in the coil length. In practice this compensation is undercompensated in character. According to the invention it is possible, by making one interval (pitch) (7) between the free turns of the coil greater than the others, to make the temperature compensation just right.
