Patent GB-491227-A (GB)
Title: Improvements in the manufacture of ethers
Filed: 1937-02-27
Abstract: For the production of ethers, dialkyl or acid alkyl esters are heated with water to cause partial hydrolysis, and the mixture is distilled, the vapour being fractionated to separate the ether, while the alcohol is returned in liquid state to the reaction vessel, the requisite water being added as liquid or steam, the hydrolysis and distillation being effected in a single stage in a number of inter-connected reaction vessels <PICT:0491227/IV/1> the vapour outlets of which are connected in parallel, to the fractionating column.  Reactive liquor which may be prepared from an olefine or alcohol and sulphuric or phosphoric acid, is led into a reaction vessel 5 from which it overflows into a second vessel 6, both being connected by pipes 2 to a fractionating column 7.  For the absorption of propylene, sulphuric acid of 80-92 per cent strength may be used which is diluted for the hydrolysis to 40-80, preferably 60 per cent, but other strengths may be used at different pressures.  Dilute alcohol from the bottom of the column 7 is returned to the reaction vessels 5, 6, by a pipe 23.  The ether from the top of the column 7 is condensed at 27, and uncondensed olefine is returned to the reaction vessels and assists in the separation of the ether. Specifications 362,593 and 427,223 are referred to.  The Specification as open to inspection under Sect. 91 includes also the production of mixed ethers described in Specification 491,441, and states that the ether may be separated from the hydrolysed liquor by means of a solvent or by injecting an inert gas at the desired temperature.  This subject-matter does not appear in the Specification as accepted.

Class 75(iii) In an electric igniter for cigarettes &c. comprising a torch normally located in a housing and having an electrically conducting part which when the torch is withdrawn from the housing bridges contacts successively to close and open the circuits of a battery or batteries in series with an inductor thereby to produce sparks for igniting the torch, the housing comprises a base 3, Fig. 5, from which extends upwardly a tube 9 for receiving the torch 18, and constituting a final reservoir 16 in the lower portion and supporting a tubular socket 29 having a funnel-shaped upper part 31 through which liquid fuel can be poured into the reservoir 16 without dismantling the lighter. Outwardly radiating ribs 25 on the tube 9 define pockets for receiving an inductor 27 (not shown) and batteries 28 which are all connected in series by contacts 57, 65 provided on the base 3 and on a top flange 24 on the tube 9, the electrical ignition contacts 40, 41 being carried in the socket 29, and the outer shell 2 of the housing is removable to provide access to the batteries. The fuel reservoir 16 has an absorbent filling, e.g. cotton wool and an absorbent pad 20, e.g. of asbestos, on which rests the wick of the torch 18 when the latter is not in use. The torch 18 comprises a metal tube having a flared lower end 23 which acts as a piston during withdrawal of the torch from the tube 9, producing a zone of reduced pressure beneath it into which air is drawn through radial groups 38 in the socket 29 to produce with the fuel vapour a combustible mixture. A flange 72 may be provided on the torch to assist extinction of the flame when it is replaced in the tube 9. The ignition contacts 40, 41 are secured to the socket 29 by pins 45, 46, which comprise resilient wires bent in zig-zag form and extend through the grooves 38, so that when the torch 18 is removed the flared end 23 raises the inner ends of the contacts 40, 41 into engagement with contact strips 42, 43, also carried by but insulated from the pins 45, 46 and connected through terminals 49, 50 with leads from the series-connected coil 27 and batteries 28. The electrical circuit is thus completed to be broken when the end 23 leaves the contacts 40, 41 to produce sparks from the latter to ignite the wick of the torch. Specification 676,434 is referred to.

Title: Means for monitoring the strip tension distribution in a strip mill
IPC: G01L5/04
Filed: 1965-02-12
Abstract: 1,088,652. Measuring strip tension electrically. ALLM€NNA SVENSKA ELEKTRISKA A. B. Feb.12, 1965 [Feb.13, 1964; Sept. 21, 1964], No.6127/65. Heading G1N. The tension distribution across the width of a moving strip (e.g. of steel in a rolling mill) is measured by passing the strip over a roller which has a pressure sensitive band arranged helically across its width Fig. 1 (not shown). The pressure sensitive band comprises a helical slot 2, Fig. 2, in the roller 1, in which are situated a plurality of magnetostrictive, transformer-steel, plates each having two rectangular holes and four circular holes 11, 12, 13, 14. Narrow portions 6 of each plate, surrounding the rectangular apertures, allow the plate to be deformed by the pressure of the moving strip, applied to a projection 10 of the plate, and such deformation causes variations in the voltage generated in a sensing coil wound in the holes 13, 14 by an exciting current applied to a coil wound in the holes 11, 12, the sensing coil being connected to a meter 18. Alternatively, Fig.3 (not shown), the roller (1) may carry a plurality of rings (20), each having a pair of oblong slots (24) in it and each being keyed to the roller (1) by a projection (31) engaging a helical slot in the roller. Variations in the inductance of a coil (23) wound in the slots indicate the pressure variations applied to a point (22) between the slots. Temperature compensation may be provided by mounting a non-stressed coil inside the roller, and connecting the measuring coil (23) and the compensating coil in a bridge circuit Fig.4 (not shown). Alternatively, a further pair of slots (30) may be provided and two coils wound in each pair of slots, the four coils being connected in a bridge circuit, Fig. 5 (not shown). This last arrangement renders the output measuring signal of the bridge independent of errors introduced by the brushes and commutator used to extract the signals from the roller, and also independent of temperature variations. The tension signal 31, Fig.6 (not shown), may be combined with a mean strip tension signal (32), and an angular position signal (33), and exhibited on a C.R.O. (50), the circuit being arranged to maintain the picture symmetrically placed on the tube, and to adjust the sensitivity of the system after each revolution of the roller to ensure that abnormally large or small signals all give a conveniently sized picture. The tension measuring signal may be used to control, for example, one or more of the cooling jets situated across the width of the strip in a steel mill to cool any excessive hot spots which give rise to the observed tension variations, in order that a strip of uniform quality and condition is produced.

Abstract: 153,826. Thompson, J. T. March 1, 1920. Audible signals; flash signals. - Relates to signal devices or alarms for use with guns, revolvers or the like. any suitable aerial or visual device being operated directly by the gas pressure resulting from the firing of cartridges, or indirectly through means controlled by the explosion gases. In the form shown in Fig. 1, a whistle 14 is interposed in the path of the gas resulting from the explosion of a cartridge C in the barrel 12 of the automatic pistol, so that a portion of the gas passes upwardly through the port 16, thereby producing a shrill note. The barrel 12 may be enlarged as in Fig. 5 to form a gas storage chamber 19 in which the gas accumulates instead of passing out of the barrel. A check valve 70 may be interposed to trap the gases, and a safety-valve 71 provided to maintain the chamber 19 closed, except when the pressure therein becomes excessive. In another form, shown in Fig. 11, a gas storage chamber 24 is situated above the barrel 12 and is provided with a check valve 30. In a still further modification, Fig. 12, an air chamber 44 is mounted above the receiver R and a piston 45 is adapted to be pushed inwardly by the recoil action of the bolt 1, thereby forcing air to open the valve 50. The air is then forced through the opening 48 into the air storage chamber 49 to operate the whistle 14. In the modification, Fig. 13, an arm 66 extends upwardly from the firing pin 60 through a slot 67 in the bolt 1, and engages a spring 68 mounted on the wall of the receiver R. On raising the spring 68 the firing pin hits the cartridge and firing automatically continues until the spring is released to engage the arm 66 and lock the pin. At the outer end of the air-chamber 55, is an opening 69 in which is inserted a whistle 14, which is operated when the piston 56 is operated by the forward movement of the bolt 1. An electric light signal may also be employed in all the embodiments of the invention, arranged in a chamber parallel with the bore of the gun. The light is used in conjunction with a manuallycontrolled switch and may be operated continuously or intermittently.

Abstract: 775,919. Moulding concrete pipes. AKTIEBOLAGET OTTO-VERKEN. March 3, 1955 No. 6264/55. Class 87(2). A machine for moulding concrete pipes, in which a core 2 moves vertically into and out of a mould 9, incorporates switch members which control the lowering and raising of the core, the operation of vibrators 7, and the operation of a concrete feeding device 22. A motor 1 is started to drive the core spindle 17 and so rotate the core 2, and a motor 4 is started to rotate a sprocket over which a chain 18 passes, having one end attached to the end of the spindle 17, and so lower the core. The core is lowered into and through the mould and is accommodated in a well 21. A counterweight 5 on the other end of the chain 18 operates a switch 6 which switches off the hoisting motor 4, brings into operation two vibrators 7 situated beneath an apertured plate 20 on which the mould rests, and starts the driving motor 8 of the concrete feeding device 22. During the last part of the downward movement of the core an apertured plate 14 is also lowered, by means not shown, on the upper edge of the mould. A helical vane 10 is fitted to the upper part of the core and bears against the surface of the concrete fed into the mould, and as the core continues to rotate it therefore rises as the concrete fills the mould. When the mould is full the counterweight 5 operates a limit switch 11 which switches off the vibrators 7 and the motor 8, and switches on a timing relay which, after an interval which may be adjusted, switches on the motor 4 to raise the core until the counterweight 5 stops it by operating a limit switch 13. During the last part of this movement the plate 14 is also lifted so that the mould, containing the moulded tube, can be removed from the machine. The switches 6, 11 and 13 may incorporate photo-electric cells.
