Title: Percussion pile drivers
IPC: B25D9/26
Filed: 1969-04-09
Abstract: 1,268,209. Pile drivers. DEMAG A.G. 9 April, 1969 [12 Oct., 1968], No. 18182/69. Heading B3H. A pile driver comprises a hammer piston 2 reciprocable in a cylinder 1, a distributing slide valve 5 for connecting one or other side of the piston with a source of pressurized gas, and means for switching the valve from a piston driving position to a piston return position, when the piston has reached a predetermined point on its return stroke. The predetermined point may be varied to alter the length of stroke of the piston. The switching means comprises a pilot duct 13, cross ducts 14a-14c, and a rotary valve 8, between duct 13 and cross duct 14a, including an axial bore and radial bores 9a-9d. In operation with the piston and distributing valve in the position shown gas passes via ducts 10, 11 to act on shoulder 16 of the piston and move it on its return stroke. When the shoulder reaches cross duct 14a gas passes via the axial bore and radial bore 9a and duct 13 to the shoulder 17 of the distributing valve 5 which is moved to cut off supply of gas to the duct 11. Gas now passes via ducts 18A, 18B into piston space 19 to move the piston on its working stroke. When the piston clears duct 14c gas in the duct 13 can pass to exhaust via bore 1A, and when the piston clears port 4A gas in space 19 and acting on the bottom surface of the valve 5 passes to exhaust via the bore 1A. The valve 5 is then forced downwardly to the position of Fig. 1 to commence a further cycle. When the rotary valve is positioned so that one of the smaller bores 9b- 9d effects communication between cross duct 14a and duct 13, the time taken to move the slide valve will be greater than that taken when the rotary valve 8 is in the position shown, and the piston stroke will be correspondingly longer. Alternatively the rotary valve may be positioned to close communication between the ducts 13, 14a in which case the piston will reach duct 14b before the slide valve 5 is moved. Thus the length of stroke of the piston can be varied. Each cross duct may be provided with a rotary valve. Actuation of the rotary valve may be effected manually or automatically. A plurality of pilot ducts each having associated therewith one or more cross ducts. Instead of radial bores the rotary valve(s) may be provided with one radial bore and a tangentially directed tapering groove extending therefrom (Fig. 4, not shown).

Title: Improvements in electric signalling systems
Inventor: TAYLOR ALAN HEATLEY
IPC: H02H7/26
Filed: 1965-05-04
Abstract: 1,135,564. Protective arrangements. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 2 May, 1966 [4 May, 1965], No. 18771/65. Heading H2K. In an arrangement for transmitting a tripping signal from one switching point in a power supply system to a circuit-breaker at another switching point, a signal of a first frequency is normally transmitted continuously over the signal line to prove that the signal channel is intact. When tripping is required, this continuous signal is replaced by signals of second and third frequencies which are transmitted alternately for short intervals. At the receiving end three circuits are tuned respectively to the three frequencies and are arranged to give an output only if the signals persist for a predetermined period. The outputs from these circuits are applied to timing circuits, each of which provide an output which remains for a predetermined time after its input ceases to control gating circuits such that a tripping signal is only produced when the signal " pattern " is correct. The receiving arrangement is such that if interference prevents effective operation of the various circuits at the first attempt, further attempts are made. The initial control equipment at the transmitting end and the final control equipment at the receiving end are duplicated, both sets of equipment at both ends having to operate effectively to bring about a tripping operation. Should any of these sets of equipment fail an alarm is given. An alarm is also given should the continuous first frequency signal fail. If both way signalling is required, two different frequencies are required for the transmission of the continuous signals from the two switching points, but the two frequencies for transmitting the tripping signal may be the same for both switching points.

Title: Improved process of and apparatus for producing fire extinguishing foam
IPC: A62C5/00
Filed: 1926-07-28
Abstract: 256,245. Excelsior Feuerl÷schgerõte Akt.-Ges., and Burmeister, H., (Assignees of Minimax Akt.-Ges.). July 30, 1925, [Convention date]. Fire-extinguishing by foam; chemicals.- A method and apparatus for producing fire extinguishing foam, consists in storing the substances for generating the foam mixed together in a closed receptacle, and generating the foam by applying water under pressure from below. Chemicals are chosen which possess practically no humidity to cause reaction. For safety, hygroscopic substances may be added to the mixture. Apparatus for producing the foam comprises a closeable receptacle a in which the mixed chemicals are stored. Water under pressure passes in through a pipe i and spraying head b with a plurality of spray pipes l to give a gyratory motion. A jet c acts either to dilute the foam or forms with an ejector m a device to assist in drawing off foam. The spraying head is located in the lowest part of the apparatus. Foam is led away by a discharge pipe d. Some of the gas fills the hollow space left by the used chemicals and in this way the chemicals remain dry above the lower end of the pipe d. Thus the chemicals sink continuously and uniformly towards the bottom. The apparatus may be constructed to be recharged during operation by means of an upper chamber n closed air-tight by a flap o. An airtight cover k serves as means for recharging with chemicals. For balancing the pressure in the upper and lower compartments, a connecting pipe q with valve r is provided. After closure of the cover k, the valve r is opened and then the flap o, for downward flow of the chemicals. For large apparatus a byepass e is provided for water to discharge above the chemicals and press them down by gas pressure. Water may also be passed into the foam pipe d through a valve g to control the viscosity of the foam.

Title: Improvements relating to the reactivation of catalysts
IPC: C10G45/62
Filed: 1962-05-16
Abstract: In a hydrocarbon conversion process, e.g. isomerization, carried out using a catalyst prepared by contacting a halogenatable inorganic oxide of an element of Groups II to V of the Periodic Table with a compound of the formula <FORM:1014882/C4-C5/1> (where X and Y may be the same or different and are H, Cl, Br, F or SCl, or where X and Y together may be oxygen or sulphur) under non-reducing conditions and at a temperature such that chlorine is taken up by the oxide without the production of free chloride of the element from Group II to V, said conversion process operating at elevated temperature and pressure in presence of hydrogen, the catalyst is at least partially reactivated by stopping the flow of hydrocarbon feedstock when evidence of catalyst deactivation is apparent, continuing to pass the hydrogen until the catalyst is at least partially reactivated and then recommencing the flow of feedstock.  Preferably, the passage of hydrogen is continued at a pressure below the conversion pressure, e.g. at least 50 p.s.i.g., the duration of the reactivation step being 1 to 100 hours.  The isomerization process is carried out in either liquid or vapour phase using C4 or higher paraffin hydrocarbons boiling up to 400 DEG  F. at temperatures below 400 DEG F., the isomerization pressure being 100 to 2000 p.s.i.g., the isomerization and reactivation temperatures and hydrogen flow rate being the same. Specified catalyst are refractory oxide selected from Groups II to V of the Periodic Table, e.g. alumina, boria, silica, titania or zirconia which may be used in admixture.  Preferably the catalyst contains (1) less than 25% weight of a metal N compound having hydrogenating activity selected from Groups VIA and VIII, e.g. platinium or palladium, and (2) 1 to 15% weight of chlorine in amounts of from 2.0 x 10-4 to 35 x 10-4 gms./sq. metre of catalyst surface area.  The example describes the isomerization of a C6 refinery light gasoline fraction, which has been previously dried, desulphurized and dearomatized, at 270 DEG  F., 250 p.s.i.g. total pressure, the reactivation step taking 4 hours at 250 p.s.i.g. and 12 hours at 100 p.s.i.g. to give increased catalyst activity measured in terms of the percentage yield of 2.2 dimethylbutane after each reactivation step, the reactivation step being carried out two times.
