Title: Improvements in machines for making and applying caps to bottles and the like
IPC: B67B3/064
Filed: 1925-06-11
Abstract: 242,907. Jonsson, A. J. June 11, 1925. Stoppers, making crown corks.- In a machine with separate tools for producing a cap and applying it to a bottle or the like, one or more members or conveyers for transferring automatically the finished or unfinished cap from one tool to another are adapted to produce pneumatically the action on the cap necessary for its transference. The machine comprises framing 3 which supports a stamping and bending tool 1 for producing the caps, a stamp 12 carried by an arm 13 thereon and adapted, in conjunction with a lower plunger 16, to force into the caps packing discs fed from a holder 10, and a capping head 22. The tools are spaced equidistantly from each other and from the axis 48 of an oscillating conveyer formed with two tubular arms 32, 33 of which the arm 32 is adapted to transfer a cap from the tool to the stamp 12 whilst the arm 33 removes a cap from the stamp 12 to the capping head 22. The tubes are connected through the axis 48 to a blast which provides sufficient suction at their mouths to withdraw a cap from the adjacent tool and to hold it whilst the conveyer is oscillated to bring the caps to the succeeding tools, the moving parts of which remove them from the tubes. The oscillation is effected against spring action by means of an arm 37 secured to the conveyer and engaged at its other end 38 by a cam 39 on a disc 15 geared to the motor 50 which drives the machine. As shown the plunger 16 is operated by a lever 17 actuated by a cam on the disc 15 which also actuates an oscillating conveyer 11 adapted to transfer the packing discs from the holder 10 to the caps. In modifications the caps are released from the tubes 32, 33 by interrupting the blast and the disc-applying mechanism is omitted from the machine.

Filed: 1926-06-17
Abstract: 253,923. British Thomson-Houston Co., Ltd., (Assignees of McNairy, J. W.). June 22, 1925, [Convention date]. Automatic circuit-breakers; cut-out arrangements. - The breaker is designed to open on steady overload or sudden heavy overload in the supply circuit L1 which may carry alternating or continuous current in either direction. The holdon circuit 16 for the electromagnet 13 is normally supplied with unidirectional current from the source L2 and, on depressing the push-button 28, the coil 29 is energized completing the circuit for the coil 14 and so forcing the arm 14a clockwise to press 'the spring-pressed arm 11 towards closing position wherein the magnetic member 15<a> is held by the electromagnet 13. During this operation the resister 27 is successively shortcircuited at 28 and 30 so that the hold-on current is in excess of normal, and as circuit-closing at 30 shorts the coil 29 the circuit of the coil 14 is opened and the arm 11 moves to bring contacts 31 and 32 into engagement. The rectifying arrangements 19, 20, 21, 22, 23, 24 are such that unidirectional current is supplied to the coil 17 to oppose the hold-on current through 16 and on steady overload the arm 15 is finally released, but if a high inductance 25 is in shunt across the coil 17, a sudden rush throws a disproportionate amount of current into the coil 17 and immediate release is effected. Various rectifying arrangements are described and an adaptation of the invention to threephase working. It is stated that operation can be effected with but one rectifier 19 and 20 employed. The circuit-interrupter is of the type described in Specification 125,279 and its operation is set out in Specification 187,993.

Title: Analyser devices for vor navigational receivers
IPC: G01S1/02
Filed: 1975-04-15
Abstract: 1494235 VOR receiver SIEMENS AG 15 April 1975 [6 May 1974] 15327/75 Heading H4D A digital VOR receiver is described using the frequency multipled reference signal as a clock signal for a bearing counter. Errors due to the use of a possibly drifting self contained clock oscillator are thus avoided. TO and FROM ambiguity is also avoided. In the VOR receiver the 30 H 3  a.m. bearing signal is selected by L.P.F.2, converted to a square wave by limiter 3 and to a series of short pulses by differentiator 4. The reference 30 H 3  signal f.m.'d on a 9960 H 3  carrier is selected by H.P.F.8 and detected by F.M. demod 9. A frequency multiplier 10 produces a pulse for every increment of bearing, e.g. if α = 1, it has a factor of X360 and gives a frequency 10,800 H 3 . These pulses are counted at 11, 0 to 359 and reset to 0, via divider 12. The counter content when a bearing signal pulse from differentiator 4 reaches a store 7 registering the counter content, is transferred to a decoder 13 for a bearing readout at 14.

Title: Improvements in or relating to the production of magnesium base alloys
Inventor: EMLEY EDWARD FREDERICK
IPC: C22C1/02
Filed: 1947-06-13
Abstract: A composition for introducing zirconium into magnesium and magnesium base alloys consists of one or more chlorides of alkaline earth metals, including magnesium, together with zirconium fluoride in the absence of potassium and/or sodium fluoride, at least sufficient chloride being used to enable the composition to melt at the alloying temperature.  Up to 20 per cent of innocuous substances may be included in the composition. These substances are compounds of zirconium or of "permissible elements" or such compounds of "zirconium alloying inhibitor elements" as do not give rise to these elements in molten magnesium.  "Zirconium alloying inhibitor elements" are defined as elements which form high melting point compounds with zirconium.  "Permissible elements" do not form such compounds and they consist mainly of zinc, cadmium, rare earth metals, silver, thallium, thorium, copper, bismuth, beryllium, lead lithium and calcium.  The chlorides alone should be fluid at a temperature of 850 DEG C. or less.  The mixture may contain at least 4 per cent of zirconium in the form of the chloride and/or fluoride, and it may contain at least 10 per cent of barium or at least 15 per cent of strontium or both metals together equivalent to at least 10 per cent of barium reckoning 3 per cent of strontium equivalent to 2 per cent of barium, the barium and strontium being in the form of chlorides and/or fluorides.  The composition may be prepared by melting the chlorides and adding zirconium fluoride to this melt. The composition may be used to alloy zirconium with magnesium or a magnesium base alloy by adding the molten metal or alloy to the substance, which may be in the form of prefused lumps, and subsequently stirring to effect dissolution of the magnesium. Specification 511,137 is referred to.

Title: Improvements in or relating to the recovery of glycerol from industrial liquors by evaporation
Inventor: CAMPBELL GEORGE REID
IPC: C11D19/00
Filed: 1952-06-23
Abstract: <PICT:0737570/III/1> <PICT:0737570/III/2> Glycerol is recovered from liquors which contain a high proportion of solids (e.g. concentrated fermentation liquors or soap lyes) by causing the liquor to flow in the form of a film down the surface or surfaces of one or more vertical tubes enclosed in a vessel maintained at sub-atmospheric pressure, said tube or tubes being heated to such a temperature that the glycerol is vaporized from the liquor and leaves a residue which remains in the fluid state.  The glycerol vapours are passed to a condenser or to a series of condensers, while the fluid residue flows from the lower part of the surface or surfaces into a vessel from which it is pumped at such a rate that sufficient fluid residue is maintained therein to form a seal for the region at sub-atmospheric pressure. The film-supporting surface may be the internal surface of a vertical tube surrounded by a jacket containing heating medium, or several such tubes may be used.  Alternatively, the external surfaces of internally heated vertical tubes may be used. Fermentation glycerol containing 56 per cent glycerol, 13 per cent water and 22 per cent residue passes from tank 4 (Fig. 1) into preheater 6 where it is heated to 138 DEG  C.  The preheated liquor then flows onto the inner surface of tube 11 through slot 10 (Fig. 2).  Tube 11, which is made of stainless steel and is 15 feet long and 1.5 inches internal diameter, is heated by steam at 190 p.s.i.g. in jacket 12.  A pressure of 31 mm. Hg. (absolute) is maintained in tube 11 by means of a vacuum pump (not shown) connected to pipe 29.  The distilled vapours pass through pipe 17 to condenser 18, which is cooled by boiling water; and a fraction of high glycerol content (97 per cent) condenses, which is collected in receiver 22.  The vapours which have not been condensed pass on to condenser 24, which is cooled by cold water, to give a condensate containing 57 per cent glycerol and 33 per cent water, which is collected in receiver 28.  The non-volatile residue is removed from the bottom of tube 11 by pump 15.

Abstract: 329,843. Soc. Anon. pour tous Appareillages MÚcaniques. March 1, 1929, [Convention date]. Addition to 310,538. Fixed-chamber apparatus. - The valve 18 controlling admission to and discharge from chambers 1, 6 is locked until both operations are completed. The increased pressure in the supply pipe consequent on the filling of the chamber 1 moves a diaphragm to which is attached the catch 24. This ceases to obstruct the bellcrank lever 11, and as the float 8 in the discharge passage falls the stop 14 tends to move beneath the rod 16. A lever 32 connected to the rod 16 carries a projection 33 which is pressed by the spring 34 into notches 39 in a cam-plate 35 on the spindle of the valve 18. The camplate must be rotated into its extreme position so that the projection 33 rises on to the sloping side of the notch; if the discharge passage is empty the ball 14 will then pass beneath the rod 16 and hold the projection 33 clear of the cam plate while the valve 18 is thrown over for fresh delivery and filling operations. As delivery commences the stop 14 is withdrawn and the projection 33 re-engaged with the other notch in the plate 35.
