Title: Improved manner of and apparatus for filling bags with finely divided or small material
IPC: B65B43/50
Filed: 1929-05-13
Abstract: 333,528. Brooke Bond India, Ltd., and Wood, C. May 13, 1929. Filling granular materials into paper bags.- Apparatus for filling tea, coffee, sugar, and like materials into paper bags comprises a rotary head 2, Fig. 1, upon which a series of arms 3 carrying funnels 5 are pivoted at 4. The lower surfaces of the arms engage a circular track 6 on a cam cylinder 7. When the arm engages the part 6<a> the funnel is lifted into the inclined position shown in broken lines so as to be in position to enter the open mouth of a bag presented by a bag feeding device, which may be as described in Specification 333,530. The opening of the bag may be facilitated by an air-blast. When the arm 3 is travelling down the part 6<b> of the cam, the small end 10 of the funnel enters the bag mouth and drags it inwards towards the rotating head as the funnel assumes the vertical position. The bottom of the bag now rests on a spring plate 13 on a head 12 rotatable with the head 2. When the arm has reached the part 6<c> of the cam, a charge of tea &c. is received through the funnel, and serrations 6d on the cam cause a shaking motion to be communicated to the funnel. Similarly, the interaction of an extension 16 of the plate 13 with a toothed rack 17 causes the bottom of the bag to be agitated. At a later stage in the rotary movement, the bag, which by reason of the bulging of the contents is already partly disengaged from the funnel, is engaged by a conveyer and drawn away to closing apparatus.. Two filling heads may co-operate to supply one closing device.

Title: Process for concentrating a multi-component liquid material and apparatus therefor
IPC: C12H6/04
Filed: 1963-04-17
Abstract: 977,686. Concentrating liquids by freezing. PHILLIPS PETROLEUM CO. April 17, 1963 [May 14, 19621, No. 15032/63. Heading F4H. In a process for concentrating solutions by freezing, one component of the solution is partly crystallized in a chiller and the crystals are then passed to a storage zone in which the crystals are allowed to grow before being passed to a purification column. As shown, beer is passed through a line 11 to a jacketed chiller 13 having a scraper 15, the resultant ice crystals and mother liquor being then forwarded to a storage vessel 19 containing an agitator 20. The crystals remain from one to ten hours in vessel 19 during which time they increase in size, and are then passed to a purification column 22. In the latter the crystals move as a compact mass towards a heater 24 which melts the crystals, part of the melt water being forced back through the crystal mass by a pulse unit 28 to remove occluded liquor therefrom and the remainder of the melt being extracted through line 25. The mother liquor is extracted from the purification column through a filter 23 and is collected in a drum 27, whence it is supplied, via line 32, to the inlet of a second chiller 13a in which the process is repeated. A third stage 13b, 19b, 22b and 25b is provided and receives mother liquor from the drum 27a of the second stage. Liquor from drum 27 may be recycled to the inlet of chiller 13 via valve 51 while liquor from drum 27a may be recycled to chiller 13 via valve 55 or to chiller 13a via valve 53. Similarly, liquor from drum 27b may be returned to chiller 13 via valve 61, chiller 13a via valve 59 and chiller 13b via valve 57. The chillers 13, 13a and 13b receive and return refrigerant from and to respective receivers 39, 39a and 39b having connections with a refrigeration unit 37. The process may be used for milk, fruit juices, vegetable juices, vinegar, coffee, tea and wine or to separate mixtures of organic materials. Specification 807,100 is referred to.

Patent GB-151997-A (GB)
Abstract: 151,997. Johnsen, F. A., and Rahbek, K. Feb. 15, 1919, [Convention date]. Electrostatic meters.-In an electrostatic apparatus the sensitiveness of which to electric potentials depends on the arrangement, as described in Specification 144,761, of a poorly-conductive member between two conductors, one of the conductors formed as a flexible strip which, owing to the shape of the poor conductor or of the strip or of both, normally touches the poor conductor along a fraction only of its length, and is caused to move towards and apply itself to the poor conductor by the attraction between the conductors on the establishment of a sufficient potential difference between them, the movement of the strip indicating the existence of this potential difference. A stiff flexible strip may be used, which strengthens the apparatus and enables it to be employed in any position. As shown, the poor conductor 1 ismounted on a curved conductor 2 and touches the flexible conductor 3. Alternatively, the poor conductor may be applied to the flexible strip 3, which is attracted towards the other conductor, or to two flexible conductive strips which are attracted towards each other; or a fixed layer of poor conductor may be arranged between two flexible conductive strips. A large resistance may be inserted between the conductor 2 and the source of potential. For use as an electrification detector, the apparatus may be enclosed in a casing having apertures to allow observation of the motion of the flexible conductor or of a distinguishing mark thereon. The flexible conductor is connected through a clip fitted with a contact spring to a metal sleeve held in the hand and so maintained at the potential of earth, whilst the second conductor is connected to a metal contact through a high resistance, such as graphite, mounted in an insulating tube. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following modifications : the poor conductor may be applied to both the flexible strip and the second conductor; the high resistance inserted between the conductor and the source of potential may comprise a mixture of graphite or the like with semi-conducting or insulating material; the poor conductor mav comprise an independent body of considerable thickness with a curved surface, metal foil on its surface forming one conductor; the electrification detector may be used as an indicating arrangement in a central telephone station, and the flexible strip mav close contacts, thus forming an electrostatic relay, which may, for instance, operate an alarm or earth a charged conductor on the existence of an excession voltage. This subject-matter does not appear in the Specification as accepted.

Title: Method and means for the automatic regeneration of received telegraph signals
IPC: H04L25/20
Filed: 1931-05-22
Abstract: 374,248. Code telegraphy. NIELSEN, T. C. V., 37, Solsortevej, Copenhagen. May 22, 1931, No. 15210. [Class 40 (iii).] In a repeating system, signal impulses are stored in condensers or relays through a distributer which is intermittently arrested for phase-adjustment purposes, and are sent on by a continuously rotating distributer. The average speeds of the two distributers are coordinated by automatic control of the field current of the driving motor. Synchronizing distributer with received signals; storing signals in condensers. At each change of polarity in the impulses received by unbiased line magnet 1, armature 11 releases cam 17 for half a revolution. The phase of shaft 28, which is independently driven at approximately the right speed, is corrected by engagement between teeth 25 and the bevelled edge 26 of the cam-driven corrector-rod 21, so that wiper-arm 27 is centred on a segment at the moment when contact 71 is closed, at the top of the rod's motion, to admit a charge of the appropriate polarity to a condenser such as 50. One condenser such as 50 is associated with each distributer-segment. In the case of block signals, the condensers remain uncharged with the exception of those corresponding to changes of polarity, since the escapement 16 does not release cam 17 to close contact 71 unless the polarity changes. The condensercharges are subsequently conveyed to sending- on relay 90 through distributer arm 84, which is mounted on a shaft 85 and remains approximately 180‹ out of phase with arm 27. Relay 90 is unbiased, so that the absence of charge on certain condensers, described above, does not prevent correct sending-on. Armature 87 may be connected either to line or (through a further distributer arm 93 on shaft 85) to multiplexed local printers such as 95. Synchronization of distributers. Shafts 28, 85 have to be synchronized with sufficient accuracy to prevent one from overtaking the other. To this end, wiper 111 on shaft 28 cooperates with rheostat-resistance on shaft 85, so that the relative phase of the shafts determines the resistance in series with field coils of the motor driving shaft 85. Modification applicable to Wheatstone morse. Wheatstone morse signals are such that if a change of polarity in one direction occurs at the end of an odd-numbered signal period, the reverse change occurs at the end of an evennumbered signal period. Wider latitude for distortion is obtainable with this code by the provision of two corrector-wheels 25 with corresponding corrector-rods, the wheels being so staggered that one corrector sets the arm 27 on to odd segments and the other on to even segments. Modification employing storing-relays. Storing relays may be used instead of condensers, Fig. 4 (not shown).

Title: An ignition attachment for the prevention of loss by theft of motor vehicles under their own power
IPC: B60R25/04
Filed: 1919-06-20
Abstract: 144,107. Kirton, T. A. June 20, 1919. Secret contact-combination switches.-For preventing theft of motor-vehicles driven by internalcombustion engines, a secret contact-combination switch is arranged in the electric ignition circuit and fixed to, or constructed with, the magneto or battery ignition device so that there are no exposed leads, and comprises multiplepoint contacts positioned by permutation rings so that, at one particular relative position of the rings, a short circuit is removed from the ignition circuit. In the construction shown in Fig. 1, the casing 1 of the combination switch is secured to the side of the magneto frame 2, and a doubleended spring brush in engagement with the magneto slip-ring passes through the switch casing into engagement with a gapped metal ring 5 secured within the casing. The front cover 10 is adapted to rotate, and its position is indicated by a pointer 16 carried by a ring mounted adjustably on the outside of the case for varying the combination of the switch. The rotary cover carries an inwardly projecting contact-arm 11 having a point 12 in close sparking proximity to the ring 5. A spindle 13 taking a bearing in the cover carries a permutation ring 14 at one end and a pointed contact-arm 15 at the other, similar to the arm 11. Both the cover and the ring 14 are marked with index numbers, and when the rotary members are correctly set, the contact points are both located in the gap of the fixed ring 5, and the sparking-circuit is effective. At all the other positions, one or both of the contact points, which are in connexion through the casing with the frame of the apparatus, are in close proximity to the ring 5, and the ignition is shortcircuited by sparking between the ring and the points. To afford additional means for changing the switch combination, the rotary cover 10 and the disk 14 may be covered by adjustable indexmarked disks held in place by screwed rings. As applied to an induction-coil ignition device, the switch casing 23, Fig. 6, is secured to the transformer casing and carries a number of rotary permutation rings 22, Fig. 9, with circular openings cut away at 25<x>. At the correct setting of the switch, a pointed contact rod 26 connected to to the high-tension coil lies in all the gaps of the rings. At all other positions, one or more of the rings has its inner periphery in close sparking relation to the contact rod, and the ignition is short-circuited.
