Title: Improvements in and relating to synchronous alternating current mains clocks
IPC: G04C15/00
Filed: 1947-10-18
Abstract: 653,260. Clocks. THORNTON, A. J. H. Oct. 18, 1947, Nos. 27924 and 30503. [Class 139] A synchronous motor clock has an auxiliary driving mechanism consisting of a weight hung in one loop of a Huyghens chain and raised by the action of the motor so that in the event of supply failure the weight will drive the clockwork. A Huyghens chain 11 passes over two drums 14 and 15, Fig. 1, and supports in one of its loops a driving weight 10 and in the other loop a tensioning weight 12a. Normally the barrel 14 is rotated anticlockwise by the weight 10 at a speed controlled by the pendulum 46 through an escapement 43, 45 and a gear train 42, 41, 40, 33. The shaft 34 on which the barrel 14 is frictionally mounted, Fig. 2, is connected to the hands. A synchronous motor 20 through the gearing 21, 22, 23, 24 continually rotates the barrel 15 clockwise at the same rate as the barrel 14 so keeping the weight 10 " fully wound." In the event of a current failure the weight 10 falls and drives the clock. The barrel 15 may be hand-wound if necessary. In the event of the clock train stopping overwinding is prevented by automatic operation of a current interrupting device 50 in the motor supply. The speeds of the two barrels 14, 15 may be indicated by two pointers moving over respective dials. In another embodiment, Fig. 6, the synchronous motor 20 through gearing 21, 22, 23, 24, drives a wheel 66 rotatable on the shaft 34 but normaly coupled thereto through one side of a dog clutch 67, 60, 68, controlled by an arm 70 of an armature 72 of an electromagnet 71. The synchronous motor thus normally rotates the hands and at the same time the drum 14 is idly rotated by the weight 10. The arrangement is such that in the event of a current failure the electromagnet 71 is de-energized whereupon the armature 72 is rocked by a spring 73, Fig. 9, and the dog clutch is moved so that the wheel 33 normally rotating loosely on the shaft 34 is coupled thereto and the weight 10 then drives the hands as before. When the current is resumed the weight 10 is gradually lifted since the barrel 15 is rotated by the motor 20 slightly faster than the drum 14 is by the weight 10. When it reaches the top the weight 10 through a link 58 operates another clutch to disconnect the barrel 15 from the wheel 24 and when the weight reaches the bottom the reverse action takes place.

Title: Improved polymerization catalyst
IPC: C08F10/00
Filed: 1959-08-17
Abstract: Alpha olefins having 3-12 carbon atoms, specifically propylene, butene-1, 3-methylbutene-1, heptene-1, dodecene-1 or styrene, are polymerised by contact with a catalyst component activated with an alkylaluminium compound, particularly AlEt3, although other alkylaluminium compounds are also mentioned.  The said component is TiCl3 cocrystallised with AlCl3, and which is prepared by reaction of TiCl4 with Al in an aromatic diluent (hydrocarbon or chlorinated hydrocarbon), removing the diluent in a washing zone and optionally washing with hydrocarbon, slurrying the reaction solids in a hydrocarbon, passing the slurry to a ball-milling zone, removing the hydrocarbon, dry ballmilling the solids and preferably slurrying the latter in a hydrocarbon.  Polymerization is carried out in a hydrocarbon diluent; in isolating the polymer, a C1-4 alkanol such as isopropyl alcohol or n-butyl alcohol, preferably in combination with a chelating agent such as acetylacetone or diacetyl, is utilized as well as further alcohol, or an acid such as hydrochloric acid, for washing the product.  Reference has been directed by the Comptroller to Specification 805,142.ALSO:TiCl3 cocrystallised with AlCl3 is prepared by reacting TiCl4 with Al powder in an aromatic diluent, passing the reaction mixture to a washing zone, removing the diluent, slurrying the reaction solids in a hydrocarbon, passing the slurry to a ball-milling zone, removing the hydrocarbon and dry ball-minling the reaction solids.  The reaction solid may be (a) washed with a hydrocarbon prior to the slurrying step; (b) slurried in a hydrocarbon after ball-milling.  Aromatic diluents specified are benzene, toluene, xylene, mesitylene, pseudocumene, ethylbenzene, cymene, tetralin, chloro- and dichloro-benzene and orthochlorotoluene, while the above-mentioned hydrocarbon may be the usual aliphatic, cycloaliphatic and aromatic solvents, including halogenated aliphatics and aromatics.  For use as a catalyst, the cocrystallised product is activated with organometallic, particularly alkyl aluminium, compounds such as AlEt3, AlPr3, Al(i-Bu)3 and Et2AlCl; organo-aluminium compounds containing halogen, alkoxy, organic nitrogen or sulphur may also be used.  The Specification refers to the following prior methods for preparing the cocrystallised product:- (1) reduction of TiCl4 with metal powders (Al,Ti); (2) reduction with metal alkyls (AlEt3) in a diluent above about 150 DEG C.; (3) heating TiCl4 + Al alkyl after the formation of a brown precipitate at above about 70 DEG C. in presence of a diluent; (4) reduction of TiCl4 with an Al trialkyl in a diluent, in temperature-graded stages rising about a 1:0.3 mole ratio of reactants; (5) reduction of TiCl4 vapour with hydrogen above 650 DEG C. in presence of AlCl3 vapours.

Title: Improvements in or relating to electro-magnetic cut-outs
IPC: H01H9/32
Filed: 1925-11-07
Abstract: 242,664. Stotz Ges. Abteilung der Brown, Boveri, et Cie, Akt.-Ges. Nov. 8, 1924, [Convention date]. Automatic circuit-breakers; springs, arrangement and disposition of; arc-rupturing devices.- Relates to automatic cut-outs of the kind provided with current-carrying spring contacts between which is inserted an insulating barrier. As shown in Figs. 1 and 2, current normally passes through the manually-engaging spring contacts 7 and through a solenoid 3. The solenoic has a core consisting of magnetic plates 4 between which is secured an insulating barrier 5 adapted to be moved between the contacts 7 or attraction of the core by excessive current in the solenoid 3. To ensure quick breaking of the circuit, the core is connected by links 18 to one end of a lever 10, which is pivoted at 12 and has springs 14 connected between its other end 17 and a fixed point 15. The arrangement is such that the initial attraction of the core 4 moves the springs over the dead centre into a position in which they can quickly complete the movement of the member 5. To deal with small overloads of long duration a thermal release is provided consisting of a bimetallic strip 8 fixed at one end and bearing with its free end on the lever 10, a heating coil 9 included in the cut-out circuit being arranged near to the strip. To reset the cut-out a spring-controlled push button is depressed, a notched projection 26 of the button engaging the upper end of the barrier 5, but the circuit is not completed until the button is released and returned by springs 25, so drawing the insulating projection 26 from between the contacts 7. To indicate the operation of the cutout a coloured pin 28 is arranged to project through a hole in the push-button when the barrier 5 is raised. A magnetic blow-out action is produced by placing the coil 3 beneath the contacts 7. In a modified form, Fig. 6, in which the circuit is broken simultaneously between two series-connected pairs of contacts the arcs between them are blown out as shown in opposite directions.

Title: Improvements in or relating to Hydraulic Apparatus for Working Materials such as Coal or Solid Ores
IPC: E21C37/12
Filed: 1967-06-19
Abstract: 1,194,001. Hydraulic infusion and blasting apparatus. HOUILLERES DU BASSIN DU NORD ET DU PAS-DE-CALAIS. 19 June, 1967 [22 June, 1966; 28 Nov., 1966], No. 28130/67. Heading F3A. Hydraulic apparatus for infusion and subsequent blasting of coal and ores comprises means (not shown) for providing liquid under low and high pressure, an expandable sleeve 11, Fig. 2, actuated by the pressure of the liquid for automatically retaining the apparatus in a borehole, a tube 13 having a single orifice for the admission of low and high pressure liquid and containing a shotfiring mechanism having at least one shotfiring liquid outlet hole 26 and a restricted outlet passage 25, the arrangement being such that low pressure liquid for infusion passes through passage 25 whilst the outlet hole 26 is closed, the outlet hole being opened subsequently by the effect of the high pressure liquid. The shotfiring mechanism comprises a pilot piston 19 and a main piston 15. The low pressure liquid flows to the passage 25 through bores 16 and 22 in the pistons and past a valve 23. The pressure of liquid in a chamber 17 normally biases the piston against its seat. However, when the apparatus is supplied with high pressure liquid, the piston 19 is lifted off its seat and the sudden reduction in pressure in the chamber 17 permits the piston 15 to set back and uncover the holes 26. In a modification, low pressure liquid for infusion is fed through a passage 32d, Fig. 4, in a piston 32b and passes through the shotfiring liquid outlet hole 31c which is therefore only partially closed. The outlet hole is opened completely upon set back of the piston under the effect of high pressure liquid. The biasing effect of a spring 33 is adjusted by a rotatable plug 34. In another embodiment (Fig. 3, not shown) the low pressure liquid passes through a piston (32) completely closing the shotfiring liquid outlet hole and through a passage in a rotatable plug (34).

Abstract: 638,441. Moulding-machines. STONE-WALLWORK, Ltd., and STEWART, R. G. Oct. 22, 1947, No. 28232. [Class 83 (i)] [Also in Group XXIX] A foundry moulding machine has a device for turning over its table comprising a piston working in an annular chamber. In the machine shown, one or each of the trunnions 6 of the table 7, Fig. 4, has a piston or vane 16, Figs. 1 and 2, adapted to move in an annular slot 12 formed by a ring 1 and cover 2 with a central boss 3 bolted to the housing 5 of said trunnion. The slot 12 is blocked by a segment 14, bolted to the ring 1 and has ports 17<SP>1</SP>, 18<SP>1</SP> and 17<SP>2</SP>, 18<SP>2</SP> at either end. Stops 22 limit the rotation of the table to 180 degrees and the rate is slowed down towards the end of each semi-rotation by the direct port 18<SP>1</SP> or 18<SP>2</SP> connected to exhaust by the control valve, not shown, being covered by the vane 16 while the port 171 or 17<SP>2</SP> is connected to exhaust through an adjustable needle valve. To prevent the initial movement from being slowed down the needle valves are paralleled by one way inlet valves. The housing has bleed ports 21 left open initially so that all air can be expelled by the oil which is preferably used as the working fluid and to immerse the bearings 8, 9. The table 7 may have pneumatic clamps or vibrators 44 or both to which the air is admitted by ports 46, 47 through the trunnions. Packing is provided at 19 'and 50. The housings 5 are carried by telescopic lift tubes 29, Fig. 4, operated hydraulically and interconnected by a linkage 37, 38, 39 to move together. The lift may be controlled automatically to give a slow start for drawing and the lift mechanism may be arranged in a pit 36.

Title: Disc brake
IPC: F16D55/00
Filed: 1972-06-16
Abstract: 1346860 Spot-type disc brakes; caliper mounting SOC ANON DBA 16 June 1972 [18 June 1971] 28250/72 Heading F2E A sliding-caliper disc brake having two brake pads movable on a fixed support, one pad being piston-operated and the other being operated by caliper reaction, has two pins traversing mutually-opposite bores in the caliper and fixed support for sliding of the calipers, each of the bores at least in the caliper or in the fixed support comprising a gap so that it has a C-shaped cross-section and so that the pins can be introduced transversely, the gaps being so oriented that the caliper can be mounted on the fixed support transversely relative to the axes of the C-shaped bores after the pins have been mounted in the other bores, locking means being provided to prevent escape of the pins through the gaps. As shown in Figs. 1, 2, 5 and 7, a pin 6 or 7 inserted in aligned bores 19 of a caliper 5 has arranged on it an anti-friction sleeve 23, a further sleeve 24 and an outer sleeve 22. Each outer sleeve 22 has flats 29 and 30 so that on assembly of the brake the outer sleeves 22 may first be turned to the orientation shown in Fig. 7, whereupon the caliper may be mounted on a fixed support 1 by inserting each pin- and-sleeve assembly in a C-shaped bore 31 of the support 1. Thereafter, the sleeves 22 are turned through 90 degrees so as to be retained in the bores 31 and are locked therein by resilient elements 35 provided in caliper projections 34 (see especially Figs. 7 and 2). The caliper is now free to slide relative to the fixed support in applying one of the friction pads by reaction. In Figs. 8 and 9, each pin 6 or 7, without any additions, is initially screwed into a threaded bore 42 in the fixed support 1. The caliper 5 has a single bore 43 on each side, each rendered C-shaped by a gap: the gap 45 on the right points towards the right, while gap 44 on the left points downwards. On assembly, a sleeve 47 is placed on pin 7, caliper 5 is tilted so that gap 45 points downwards, and the caliper is lowered until right-hand bore 43 surrounds sleeve 47. Thereafter, caliper 5 is pivoted counter-clockwise until the left hand bore 43 surrounds pin 6, and after this a sleeve 46 is placed on pin 6. Finally, two circlips 48 are introduced, each having one end 51 supported on the caliper and part of one side accommodates in opposed grooves e.g. 49, 50, Fig. 9, in the caliper and sleeve respectively, thus locking both sleeves to the caliper. Subsequent axial motion is of caliper and sleeves along the fixed pins. Dismantling is in reverse order to assembly for each embodiment.
