Title: Improvements in or relating to electric clocks or clock movements
IPC: G04C15/00
Filed: 1936-01-16
Abstract: 469,029. Electric clocks. BRITISH SANGAMO CO., Ltd., and BUTHERUS, F. R. Jan. 16, 1936, No. 1459. [Class 139] In a synchronous-motor clock having a spring-driven movement in reserve, the escapement 8 of this reserve movement is arrested, while current actuates the synchronous-motor 1, in such a position as to ensure its automatic starting when current fails. The motor 1 normally drives the shaft 4 through train 2 and a one-way ball-clutch 3. The reserve movement, consisting of spring 6 and escapement 8 drives this shaft 4 through train 12 and a second one-way ball-clutch 5. A wheel 7 winds spring 6 until it slips in its barrel at its maximum desired tension. A soft iron arm 14 is pivoted at 15 and is rigid with an arm 17 to which latter a spring blade 20 is fixed at a point remote from both ends of the arm. The lower end of blade 20 abuts a fixed stop 21 and its upper end is bent over at 22. While the motor is running, its stray flux pulls arm 14 down to the dotted position, and a pin 13 on the balance 9 wipes up past the end 22 but is prevented from return movement downwards. This holds the balance in its position of maximum potential energy, i.e. substantially at one end of its swing. The balance may be permanently locked by manually rotating a member 23 so that its pin 24 holds the arm 17 clockwise, Fig. 2. Instead of the balance, the scape wheel 11 could be locked.

Abstract: 884,598. Reducing iron ore. ELEKTROKEMISK A. S. Jan. 20, 1959 [Jan. 22, 1958; Feb. 21, 1958; Sept. 25, 1958], No. 2121/59. Class 72. [Also in Group XII] Briquettes of metallic oxide and reducing agent are reduced in a shaft furnace by the combustion of gases in contact with the briquettes, in which an oxygen containing gas such as air is introduced into the furnace at three different levels. As shown, briquettes from hopper 2 are reduced in shaft 1, air being supplied from pipes 4 and two-way valves 5 to nozzles 6-9. The nozzles are coupled in pairs diametrically opposite each other and the air is supplied to each pair alternately, e.g. 6 and 7 blow for say 5 minutes and then 8 and 9 for 5 minutes. The reduced briquettes are discharged by way of turntable 18 and flap valve 20. Shaft 1 may be made rotatable through an angle of 90 degrees to prevent local overheating at the mouths of the injection nozzles. A modification (Fig. 3) includes a central air injection pipe 22 with nozzles at four levels. This pipe may also be rotatable through 90 degrees. In a further modification (Fig. 4 not shown) centrally disposed air injection pipes may extend both from the top and the bottom of shaft 1. The discharged briquettes may be delivered directly to an electric melting furnace, reducing gas evolved therein being returned to the shaft furnace via pipe 21. Specification 717,851 is referred to.

Abstract: 698,898. Turbines. AKT.-GES. BROWN, BOVERI & CIE. Jan. 29, 1951 [Feb. 4, 1950], No. 2168/51. Class 110(iii) To compensate for the deformation caused by unequal heat distribution in the rotor and casing of an axial flow turbine, the turbine is provided with a device supplied with a flow of vaporous medium which is the same as the working medium of the turbine in such a manner that the variations in the clearances caused by the deformation of the rotor and casing serve to compensate automatically or cause to operate means for automatically compensating the deformation. In Fig. 1, a compensating tube 1 is mounted in the turbine casing 2 so that its end is within a distance of 0.5 to 1.0 mms. from the surface of the rotor 3. Steam supplied from a pipe 5 passes through an orifice 6, pipe I and a gap fsp into the turbine casing. The area fd of the orifice 6 is preferably the same as that of the gap fsp so that the pressure px in the tube 1 is then dependent upon the area of the gap fsp. As shown in Fig. 3, the pressure variation in the tube 1 can be used to operate a valve 12 through a regulator 11 or the compensating device itself can be used for this purpose. In the latter case, cooling fluid passes through the tube 1 and the amount will be controlled by variations of the size of the gap fsp. Modifications in which the compensating tube is used to operate an electrical heating device and in -which compensating tubes are mounted on diametrically opposite sides. of the turbine casing are described.

Title: Improvements in or relating to the manufacture of filter-tip and like cigarettes
IPC: A24C5/47
Filed: 1936-01-24
Abstract: 469,415. Cigarette-making machines. MAY, R. F. Jan. 24, 1936, No. 2342. [Class 130] Bands 11 are wrapped around axiallyaligned lengths of cigarette rod 1, 1a and filter tips 2 by means 20 moving lengthwise of the assemblage in a direction opposite to the feed movement, the wrapping operation taking place while the assemblage is stationary. Cigarette rod lengths and intervening tips are discharged from hoppers 3, 3a, 4 into pockets in an intermittently rotating drum 5 and are withdrawn therefrom by camactuated linkwork 8d, 8 into alignment on a belt 9 which moves either continuously or intermittently. The assemblage passes into a C shaped guide 9c, the opening being on the lower side, and is stopped by a camcontrolled finger 10 over transversely fed strips of wrapping material 11. The strips are advanced over a perforated table to the inside of which suction is applied, the final section 13 of the table being pivoted and raised at the appropriate instant to bring the band 11 against the superposed rods and tip. As the stop 10 is lifted, the assemblage with the attached band passes over the extension 13f of the table, is accelerated between rollers 17, 17a, and passes through a further guide section 9d on to an intermittently moving belt 18. A reciprocating wrapping-garniture 20 travels forwards with the assemblage which then stops, while the garniture returns and effects the wrapping. This is preferably done in two operations. The wrapped assemblage is then accelerated between rollers 22, 22a, and lodged in a pocketed intermittently rotated drum 23, midway of the width of which is arranged a knife 26. Side plates 24, 24a and a covering quadrant ensure the proper positioning of the lengths and their discharge on to a final conveyer.

Filed: 1975-01-20
Abstract: 1466032 Shovelling machines POCLAIN 20 Jan 1975 [21 Jan 1974] 2429/75 Heading H1F Adjustment of the length of a rigid jib, e.g. a jib of a shovelling machine, is facilitated by assembling the jib from elements 1, 3 and 5. The working tool-carrying element 1 is pivotally connected at 6 to the element 5 and can be rigidly secured to the element 5 when a pin 7 is inserted through a hole 8 in the element 1 and one of the holes, e.g. holes 9a-9c, disposed in the element 5 at the corners of a polygon. The element 5 can he rigidly secured to the element 3 by two pins 10, 11 passed through two of the holes in the element 5 and two of a series of holes, e.g. holes 12a-12d, in the element 3. The spacing of the holes in the element 3 equals the successional spacing of the holes in the element 5. The length of the jib is varied by removing the pin 7 and one of the pins 10, 11 from the jib, rocking the element 5 about the other of the pins 10, 11 until, dependent upon the direction of rotation of the element 5 about the pin 11, one of the two adjacent holes in the element 5 aligns with one of the adjacent holes in the element 3, and re-inserting the previously withdrawn pins in the new aligned holes in the elements. The sequence of operations can be repeated to vary the length of the jib as desired. Preferably the holes in the element 3 are substantially in alignment, the polygon is an equilateral triangle, and the element 5 comprises parallel side plates connected by a central beam 19 embracing the pivot 6 so that it will abut the element 3 when the element 5 is locked to the element 3 by pins 10, 11.

Title: Improvements in fuzes for bombs and the like
IPC: F42C5/00
Filed: 1943-02-13
Abstract: 581,896. Fuzes for bombs and depth charges. MIDGLEY, A. H. Feb. 13, 1943, No. 2432. [Classes 9 (i) and 9 (ii)] A fuze for bombs and depth charges is constructed so that it is respon-ive to steady fluid pressure at a predetermined depth of immersion, but is not responsive to impulsive pressures such as pressure waves produced by the detonation of another bomb or depth charge. The fuze comprises a cylinder a, a packed piston d operating in the cylinder a piston-rod f detachably connected by means of a ball i with a strikercarrying sleeve h, a spring e surrounding the piston-rod, and a striker spring k disposed between the end of the piston-rod and the striker sleeve. The piston is attached to the piston-rod by a nut l adapted to be received in a central recess of a detachable perforated capplate m for the cylinder a. The perforations m<2> in the cap tend to filter out impulsive pressures and it is stated that the compression under impulsive pressure of the spring e and the air in the cylinder is not sufficient to allow the ball i to reach the escape opening p in the cylinder extension for release of the striker, whereas under steady hydrostatic pressure the striker is released and the bomb fired at the prescribed depth. Adjustment for depth is effected by varying the confined air space in the cylinder by the addition of water to the air space through a supply aperture closed by a screw plug r. A hand-withdrawn safety pin n is passed through the piston-head nut to prevent firing during handling. Reference has been directed by the Comptroller to Specification 22162/05, [Class 9].

Abstract: 694,135. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 31, 1951 [Feb. 16, 1950], No. 2449/51. Class 35. A variable speed D.C. motor comprises a polarized rotor and a stationary armature having three windings 1, 2, 3 energized in succession by means of a distributer switch 19 through saturable reactors 25, 29, 33 which serve to facilitate the commutation. The rotor field winding 4 is energized through slip-rings 6, 7 and a controlling rheostat 12 from the D.C. mains 10, 11. If desired, a quadrature commutating winding 14 energized through sliprings 15, 16 may be connected in the armature circuit. The distributer 19 may comprise a series of cam-operated contacts, but as shown it consists of a series of stationary contacts 1c, 2c, 3c, which are energized in sequence by a conducting arm 21 mounted on the rotor shaft 5 and connected through a rheostat 24 to the supply line 10. In order to assist commutation, each stator winding is connected to its corresponding distributer segment through a saturable reactor whose control winding is energized in dependence on the voltage across the other two windings. Thus, for example, winding 1 is connected to 1c through coil 26 of reactor 25 whose control winding 27 is connected in series with resistor 28 across stator windings 2 and 3.
