Abstract: 693.810. Land mines. SORLINI, R. Nov. 2. 1951, No. 25684/51. Class 9(ii) A mine intended to be hidden in the ground has a conical casing 1 to which a cover 2 is secured and contains an explosive charge 3 surrounded by elements 4 of hard material e.g. rock or metal. In addition the nose 5 has a recess accommodating a nose-piece 6 containing an auxiliary explosive charge 7 to expel the casing 1 out of the ground. A percussion device communicating with ignition means is held by a fork adapted to be withdrawn or ruptured to release the device. The main charge 3 secured in position by a pin 8 surrounds a tube 9 communicating with the nose-piece 6. Within the tube is an ignition cap 10 and a delay charge 12. Adjoining the tube 9 is a detonating cap 13 for firing the main charge and below this is a delay charge 14. In the mine cover 2 is a percussion device 11 held by a fork 16 which can be withdrawn by a pull or the limbs 17 of the fork may be ruptured by pressure on the cap 15. On removal or fracture of the fork the percussion device can initiate the ignition cap 10 to fire the delay charge 12 and hence the charge 7 which .then expels the casing and its cover out of the ground. The delay charge 14 is ignited by the nose charge and initiates the detonator to fire the main charge 3 and hence hurl the elements 4 horizontally.

IPC: C22C1/02
Filed: 1944-12-29
Abstract: A method of treating magnesium base alloys containing at least 2 per cent aluminium and at least 85 per cent of magnesium wherein a carbonaceous material in sufficient quantity (according to the material and its method of use) is mixed throughout the body of the alloy in a molten condition for a sufficiently long period to produce a grain size and micro structure in the solidified metal similar to those obtained by superheating the alloy.  The alloy is preferably treated at a temperature not exceeding 800 DEG C. and materials used may be such as to hibenate carbon in active form at the temperature of treatment.  The said materials may comprise a carbonaceous gas, such as a hydrocarbon gas, or a carbonate capable of reacting with molten magnesium to give reactive carbon. A finely divided solid such as coal, coke or peat or graphite may be used.  Finely divided carbon is preferably used in amount from 0.005-0.5 per cent by weight of the alloy treated.  After treatment the melt is agitated and treated with a refining flux. The material used should be free from metallic halides and the metal treated should be free from chlorides throughout its bulk. The material may be added as an agglomerate mixture of carbon with magnesium or a magnesium base alloy of about the composition of the alloy being treated.  The treatment of alloys containing zinc and maganese in addition to magnesium and aluminium, is referred to.  Specifications 359,425, 483,747, 483,813 and 608,941 are referred to.

Abstract: All-trans 1,14 - di - (alkoxycarbonyl) - 5,10 - dimethyltetradecaheptaene - (1,3,5,7,9,11,13)s and 1,18 - di - (alkoxycarbonyl) - 3,7,12,15 - tetramethyl - octadecanonaene - (1,3,5,7,9,11,-13,15,17)s and the corresponding compounds which contain two further methyl groups respectively in positions 1 and 14 and positions 1 and 18, are prepared by subjecting 4,9-dimethyl - dodecatetraen - (2,4,8,10) - yne - (6) - dial - (1,12) or 2,6,11,15 - tetramethyl - hexadecahexaen - (2,4,6,10,12,14) - yne - (8) - dial - (1,16) to condensation in an inert solvent, preferably methylene chloride, with an alkoxycarbonyl methylene-triphenyl-phosphine or a (1-alkoxycarbonyl ethylidene)-triphenyl-phosphine (either of which may contain alkyl or alkoxy substitution in the phenyl nuclei), splitting off triaryl-phosphine oxide from the condensation product and then partially hydrogenating and isomerizing the resulting ester at the central triple bond by hydrogenation in the presence of a lead-inhibited palladium catalyst on the one hand, and submission to heat or irradiation with light on the other hand.  Alternatively the same dialkoxycarbonyl-polymers may be prepared by subjecting either of the dialdehydes to partial hydrogenation and isomerization at the triple bond by the above-described methods, condensing the resulting partially hydrogenated and isomerized compound in an inert solvent with one of the aforesaid phosphine compounds and splitting off triaryl-phosphine oxide from the condensation product.  In both methods, the condensation step may be effected at room or slightly elevated temperature, the reagents being used in equivalent amounts or with excess of the triaryl phosphine reagent and an inert solvent may be present.  The splitting off of the triaryl phosphine oxide from the condensate occurs on standing at room temperature and more rapidly on heating; this product may be purified by treatment with aluminium oxide.  The catalytic partial hydrogenation may be effected in the presence of quinoline and an inert solvent.  This yields the cis-isomer which is then isomerized to the all-trans form, if desired, in a solvent.  Examples describe the preparation of the all-trans crocetine dimethyl, diethyl and dicetyl esters, all-trans bixine methyl ester and all-trans norbixine diethyl ester.  The esters are useful as colouring additives to foodstuffs.  The triaryl phosphine reagents may be prepared by condensing an a -halo-acetic acid alkyl ester or an a -halo-propionic acid alkyl ester with a triaryl phosphine in an inert solvent and treating the resulting phosphonium halide (e.g. bromide) with a hydrogen halide binding agent, such as a sodium alcoholate.

Title: Improvements in and relating to automatic railway control systems
IPC: B61L25/04
Filed: 1961-07-20
Abstract: 923,915. Train control systems. BROWN, BOVERI & CO. Ltd. July 20, 1961 [July 20, 1960], No. 26316/61. Class 105. In a railway control system for controlling the running of a train in accordance with a predetermined programme, including time control means for determining any deviation between the actual timing of a train and its programme timing, proximity control means are provided which determine the proximity of the train to a preceding train and override the timing control means in controlling the running of the train. A programme control unit PS includes a programming device, e.g. a perforated tape driven from the train axles, which provides a marker signal which is compared with positional signals S 2  received from track apparatus to synchronize the programme with the train's position on the track. The tape also provides a time signal, a presecribed train speed signal, a maximum admissible train speed signal, a brake signal, a tractive current control signal and a maximum admissibly tractive current signal. Unit VK receives the programme time signal and compares it with a standard time signal t 1  to produce a difference signal #t. The proximity control unit AK is supplied with signals p, p<SP>1</SP> and p<SP>11</SP>, which are a measure of the train weight, the number of braking axles &c., which with the train speed determine the train's braking distance; with signals S 2 , V 2  and S 1 , V 1  which are a function, respectively, of the position and speed of the train and a preceding train and with a signal which is a measure of the acceleration of the preceding train. The unit AK supplies to the programme unit PS a rapid emergency brake signal ef when the relative distance between the train and the preceding train drops to a value equal to the train's braking distance plus an additional safety distance, and a signal eif which increases with increase in the speed difference between the trains and with decrease in distance between the trains. The signals generated in and applied to the programme unit combine to produce a motor control signal i and a braking signal f. The programme speed signal is increased, in the event of train delay, by the signal #t from unit VK and decreased by signal eif from unit AK. In the event of decreasing distance between the trains and a large speed difference, signal eif assumes precedence over signal #t and the train speed is reduced.

Class 110 (3). [Also in Group XXXIV] In an exhaust gas driven turbine and supercharger blower assembly, the turbine rotor and the blower impeller are mounted in overhung relation on a common shaft which is supported in the casing by means of two bearings. An annular space 3 is provided in the casing near the bearing 4 which is disposed adjacent the turbine. rotor and engine lubricating oil is circulated through the annular space to provide a cooling effect. Oil for lubricating the shaft bearings is supplied from the lubricating system of the engine on to a rotary disc 7- which causes atomization of the oil. The engine lubricating oil may be supplied through a cooler 10 disposed in the air inlet to the blower; the oil then passing to an inlet 1 in the casing. Oil passes through a duct 6 to impinge on the atomizing disc 7, the oil mist serving to lubricate, the bearings. The oil discharges from the space 8 through the duct 9 to outlet 5. Some oil from the inlet 1 flows through passage 2 to the annular space 3, thereby tending to cool the bearing 4 adjacent the turbine rotor. This oil then discharges through outlet 5 together with the oil from the lubricating space 8. The velocity of discharge of the cooling oil augments the discharge of the lubricating oil through the duct 9.

Title: Improvements in or relating to labelling machines for applying thermoplastic labels
Inventor: FAIREST MORGAN
IPC: B65C9/24
Filed: 1952-10-24
Abstract: 730,798. Electric air heaters for labelling machines. FAIREST, Ltd., M. Oct. 26, 1953 [Oct. 24, 1952 ; Nov. 20, 1952], Nos. 26689/52 and 29297/52. Class 39 (3). [Also in Group XV] A labelling machine supplying thermoplastic labels carries an air heater 9 comprising a tube 10 having an internal diameter a small fraction of its length and an axial insulating rod on which is wound a helical resistance wire 20 so that compressed air from a pipe 27 passes through the tube over the resistance to an outlet 31 at the other end of the tube, which is adjacent a label. Alternatively, the heating resistance is disposed externally of the tube 10 through which the air flows. The air outlet 31 is shaped to correspond with the size and shape of the label. Cylindrical articles 1 to be labelled are spaced on a conveyer. 2 by a worm 3 and pass along a wall 4 to be rotated by an endless belt 7 against a stationary side 5 of an intermittently rotated hexagonal suction member 6 delivering labels. A stack 8 of thermoplastic labels is moved against one side of the member 6 while the latter is at rest to extract a label, which is moved towards the outlet 31 of the air heater and thus heated to render it adhesive. The member 6 rotates on a horizontal or vertical axis. Slag wool or other insulation is packed between an outer casing 18 and a tube 13 surrounding the tube 10. The absence of an article in the feed succession allows detectors 33, 42 adjacent the conveyer to close micro-switches 32, 43 respectively. Closure of switch 32 energizes a solenoid 34 moving a piston 37 in the compressed air supply line so as to divert the air supply to the atmosphere through a pipe 41 ; and closure of switch 43 prevents the stack 8 of labels from moving towards the hexagonal member 6 to deliver a label. Mechanical detectors other than microswitches may be used, or electronic devices responsive to capacity variation across a gap in the feed-path of the articles.
