Abstract: 846,327. Building and doffing mechanisms stop motions. PRINCE-SMITH & STELLS Ltd. Nov. 28, 1958 [Nov. 28, 1957], No. 37162/57. Classes 120(2) and 120(3). An electrically driven spinning &c. machine comprises a main driving motor, a reversible auxiliary motor, which is arranged automatically to move the ring-plate in either direction between a normal winding position and an under winding position, and switching means for stopping the auxiliary motor when either position is reached and for stopping the main driving motor substantially when the underwinding position is reached. Building mechanism. In Figs. 1 and 2a cam 15 co-operates with a follower 16 mounted on a rocking arm 17 alternately to pull and release a chain 18 which is anchored at one end to a pulley 19 mounted on a shaft 20 and at the other end is wound about a pulley 21, and the motion is transmitted through a pulley 23, a chain connection 24, a lifter rail chain rod 25 and a chain 26 to a lifter 14 which reciprocates a ring-plate 12. As shown in Figs. 1 and 3 periodic advancement of a ratchet wheel 29 rotates a worm 31 and worm wheel 32 to reduce the effective length of the chain 18 and thus raise the datum point of each traverse. The ratchet wheel 29 is connected by gearing to the shaft 20 on the right hand side of the machine (Fig. 1), so that both chains 18 are shortened simultaneously. During the building the ring-plates 12 rise progressively from the position P to the position Q (Fig. 2). Stop motions; initiating doffing and donning. One of the shafts 20 carries cams 56, 57, 58, which operate micro-switches 59, 60, 61 respectively for stopping and starting the main motor and the auxiliary motor 50 (Fig. 3). When the ring-plates 12 reach position Q a yardage counter 66 energizes a solenoid 55 to operate a pawl release lever 54 associated with the ratchet wheel 54 and close a switch 62 (Fig. 1). This starts the auxiliary motor 50 which lowers the ring-plates 12 to the underwinding position U (Fig. 2) and lights an indicating lamp. The fall of the ring-plates 12 opens the switch 61 to stop the main motor so that a few turns of yarn are wound on the spindle 10 as it idles. When the ring-plates reach the position U the switch 59 opens. stopping the auxiliary motor 50. When fresh bobbins have been donned, the yardage counter 66 is reset, and this extinguishes the lamp and de-energizes the solenoid 55 to engage the pawls 28 with the ratchet wheel 29. A starter switch is then closed to start the auxiliary motor 50 in the reverse direction and the main motor. The ring-plates are raised to the position P where the switch 60 opens to stop the motor 50, and the winding operation recommences. A manual stop control may be provided.

Title: Improvements in or relating to the preservation of foodstuffs and other materials
IPC: A23L3/36
Filed: 1961-10-17
Abstract: 952,658. Preserving food &c. E. BECKMANN, D, BECKMANN, and U. BECKMANN. Oct. 17, 1961 [Oct. 21, 1960], No. 37209/61. Heading A2D. A perishable substance is preserved by rapidly cooling it below the freezing point of water by introducing it into a vacuum in finely dispersed form whereby immediate evaporation occurs of at least a portion of its water content, and storing the cooled substance in a de-aerated condition. The substance may be sterilized or pasteurized before freezing and if it does not contain enough water to produce an adequate cooling effect upon introduction into the vacuum, such water is added initially; steam may be employed both for the sterilization and the dilution. The vacuum may range from 5 mm. Mg. down to 0.5 mm. H 2  depending on the length of storage desired. The dispersion can be effected by atomisation through nozzles or by directing the substance on to a rapidly moving surface, and the frozen substance can be stored in a bulk refrigerated vacuum storage vessel or filled into vacuum-tight packages of a size for consumer use, which are then stored under refrigeration. Substances mentioned: natural and synthetic foodstuffs, particularly milk, cream, butter, eggs, fruit juices, vegetable extracts such as coffee or tea, and medicines, drugs and blood plasma. Referring to Fig. 1, cream from a storage vessel 1 or centrifuge 2 is pumped to a pre-heater 5 filled with balls 6 of stainless steel; steam is introduced into the preheater through a duct 7 at sufficient pressure to heat the cream to about 90‹-100‹C. The heated cream is beaten in a rotary beater 32 and then forced under a pressure of from 1 to 10 atmospheres through a nozzle 8 into a vacuum vessel 9 wherein a vacuum of 0.5-4 mm. Hg, depending on the length of preservation desired, is maintained by a steam jet 10. The cream falls frozen to the bottom of the vessel as a loose snow-like mass which appears to be almost dry and has a uniform temparature of about -10‹C. The frozen cream is compacted and delivered by a screw conveyer 11 to an evacuated refrigerated storage container 13 cooled by a cooling coil 15 within an evacuated jacket 18 or by spraying a cooling liquid down the inner wall of the jacket. The cream may be removed from the container through a bottom opening 17 by introducing under pressure through line 16 an inert gas or water vapour; the latter has the effect of warming up the cream so that it becomes liquid. In modifications, electrical high frequency heating apparatus may replace the steam pre-heater 5, 6, 7, or a pre-heater may be entirely absent, and the dispersion may be facilitated by use of an inert gas and a rotating atomiser or effected electrostatically. In the preservation of eggs, they are first cleaned with steam, then crushed and the shells are pulverised very finely until the particles cannot be detected.

Title: Improved apparatus for severing wrappers from webs and feeding said wrappers to package-making machines
IPC: B65B41/18
Filed: 1930-12-12
Abstract: 368,836. Cutting and perforating machines. ROSE, A. G. and ROSE BROS. (GAINSBOROUGH), Ltd., Albion Works, Gainsborough, Lincolnshire. Dec. 12, 1930 No. 37479. [Classes 31 (i) and 31 (ii).] Relates to web-feed apparatus of the type in which the web is provided at spaced intervals along its length with designs or the like and control areas preferably in the form of translucent or opaque spots, one in definite relation to each design, the web being fed past a lamp, which directs a beam of light to it and thence to a light-sensitive device, the change in current in the device consequent upon the passage of the control area through the beam of light being utilized to co-ordinate some other operation such as cutting or perforating, and consists in the provision of an electromagnetically-operated clamp controlled by the light-sensitive device upon the appearance of a control area in the beam of light to interrupt the forward travel of the web and clamp it during the subsequent operation. The web 10 is fed by a continuously rotating roll 12 and its co-operating roll 13, until a control area comes over an aperture in the feed table beneath which are located a lamp 19 and a selenium cell 20, connected through a relay 26, battery 25, and contact members 33, 34 with an electromagnet 24. The contact 33 wipes over a conducting ring 31, the periphery of which is broken by an insulating segment 32, attached to the roll 12 ; the contact 34 also bears upon the ring 31 but upon a reduced diameter thereof so that it never contacts with the segment 32. Owing to the presence of an opaque area, the amount of light reflected by the web from the lamp 19 to the cell 20 is varied, the current variation produced being employed to attract an armature 22 of the electromagnet 24 and thus rock a bell-crank lever 21 to lower the clamp 23 against the upper surface of the feed table and arrest the motion of the web. The cutter 18 then operates. The roll 12 continues to feed the web 10, which accumulates behind the clamp 23, until a recessed portion 28 of the roller 12 comes over the co-operating roller 13 when the web ceases to be fed forward. The insulating strip 32 has meanwhile engaged the contact 33 to break the circuit of the electromagnet 24, the armature of which is accordingly retracted by spring means to raise the clamp 23, at the moment when an arcuate portion 35 on a second continuously rotating roller 15 comes into operative engagement with its co-operating roller 16. The roller 15 draws the web forward until it is rendered inoperative by the relieved portion 29 of its periphery coming over the web, at which time the first roll 12 again becomes operative.

Abstract: 1,061,401. Change speed control. BROCKHOUSE ENGINEERING CO. Ltd. Sept. 27, 1963 [Oct. 5, 1962], No. 37701/62. Heading F2D. In a change speed control wherein a manual control valve 17 selectively supplies pressure liquid through lines 20, 21 to forward or reverse ratio establishing clutches, ratio shift from forward to reverse or vice versa is prevented by moving a locking rod 29 into the path of the valve spool 17 when a pump driven from an element of the gear exceeds a predetermined speed and produces a pressure difference on the ends 25, 26 of a piston 24 to move the latter up against the bias of a spring 38. The pump which may be input or output driven supplies pressure fluid through a Venturi restriction 40, which produces a local static pressure reduction at a tapping 41 communicating with the end 26 of the piston 24, and lines 39, 19 to the control valve 17. The gear may be preceded by a fluid coupling as torque converter supplied with pressure fluid from the line 39 through a part 46 of a relief valve 45 which has a vent part 47. The valve spool 17 has lands 17a, 17b and a rib 32 therebetween, the distance between the rib and lands being sufficient to permit movement of the spool 17 to a neutral position whilst the rod 29 is in its locking position. When the piston 24 is in its upper position it opens a passage 42a by-passing the Venturi 40. The change speed gear may be of the type described in Specification 992,242.

Abstract: 1,122,844. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 7 Sept., 1965 [21 Sept., 1964], No. 38484/64. Heading G6C. In a sodium cooled fast reactor, acoustic generators are provided to indicate either the pressure of gaseous fission products in fuel element sheaths, thus indicating a sheath leak or the temperature of the sodium above a predetermined value. Monitoring of the temperature may also provide a power level indication. The generator incorporates a fissile mass which generates heat during reactor operation. Coolant sodium in the vicinity of the fissile mass is caused to boil in accordance with the degree of cooling of the mass which depends upon either the gaseous fission product pressure or the coolant temperature. The boiling sodium generates the sonic signals either directly by bubble formation or through an orifice. In the upper end of fuel element sheath 11, Fig. 1, the compartment 15 contains as a heat transfer medium, liquid lead, the level of which depends upon the pressure of the gaseous fission products. The fission material 14 heats the liquid sodium in the compartment 12 to a temperature dependent upon the level of the lead in 15 and thus also upon the fission gas pressure. Boiling of the sodium is indicated by an acoustic signal at orifice 13. In a further embodiment the fission gas pressure controls a bellows which determines the orifice opening size. To indicate a temperature limit, a fusible member controls the transfer of heat from the fissile mass in the acoustic generator to the coolant sodium.
