Title: Improvements in or relating to the packaging of flowable substances
IPC: B65B51/02
Filed: 1948-12-29
Abstract: 675,274. Packaging. NICOLLE, C. Dec. 29, 1948. No. 33,382/48. Class 94 (i). A flowable substance is packaged between two recessed sheets, which are secured together along opposed flat portions to form a number of cells for the reception of the substance, each sheet being formed with grooves which cooperate to form a filling orifice and a distributing channel network leading from the orifice to the cells. In one form, Fig. 1, the cells 2 communicate through branch channels 3 with a main supply channel 3<SP>1</SP> terminating at one end in a filling aperture 4, adapted to receive a tapered filling nozzle 5, and at the other end in an air vent 3<SP>11</SP>. The package may be heated during the filling operation if the substance solidifies at normal temperatures. After filling, the channels 3 are sealed, e.g. by a crimping operation, and the portion containing the channel 3<SP>1</SP> is removed by cutting along the line a-b. Alternatively, the channels may be sealed after the removal of the channel 3<SP>1</SP> by dipping the package in a sealing composition. In a modification, Fig. 8 (not shown), the channel 3<SP>1</SP> communicates directly with the wider ends of the cells and in a further modification, Fig. 6 (not shown) the package is filled by gravity through a central orifice. In a second form, Fig. 7, the first cell 2<SP>1</SP> is in series with three cells, 2<SP>11</SP>, 2<SP>111</SP> arranged in parallel, and in a third form, Fig. 10 (not shown), the cells are arranged on opposite sides of a central filling channel. Notches 10 may be provided to facilitate the opening of the package by tearing.

Abstract: 644,862. Projector lamps. GENERAL ELECTRIC CO., Ltd., and SMYTH, J. B. S. Nov. 11, 1946, No. 33427. [Class 75(iv)] [Also in Group XL(a)] A studio or stage lighting fitting employing a H.P.M.V. lamp comprises at least one pivotally mounted reflector normally forming part of the optical projection system of the lamp but which can be closed at least partly around the lamp during operation of the fitting to prevent escape of light and to keep the temperature of the lamp sufficiently high for the vapour pressure in the lamp to be maintained when the power supply is below the normal operating value. A H.P.M.V. lamp mounted on holders 3, 4 in a casing 1 has associated with it a system of reflectors 5-9 of which two 8, 9 can be rotated about axes parallel to the lamp axis by means of a lever 10 and links 11, 12. In the dotted position of the pivoted reflectors shown in Fig. 2 the lamp is completely enclosed. A snap action is given to the operating mechanism by springs 13, 14 and stops may be provided to locate the pivoted reflectors. When the reflectors are closed around the lamp the power to the lamp is reduced by inserting a resistor into the electrical circuit either by manual or automatic switching and an interlock mechanism including a relay having an operating coil across the lamp may be provided so as to prevent the pivoted reflectors from being opened and the power to the lamp increased until the voltage across the lamp has reached a predetermined value. Means preventing the main supply from being switched on when the pivoted reflectors are in the open position may be provided. The ventilation to the lamp may be cut off when the reflectors are closed. Ancillary electrical equipment is contained in a housing 15 under the casing 1. Specifications 573,590, 574,135, [both in Group XL], and 644,876 are referred.

Title: Apparatus for Attaching Tear Strips to a Web of Wrapping Material.
Inventor: WAHLE GUNTER
IPC: B31B1/90
Filed: 1966-07-26
Abstract: 1,195,224. Attaching tear strips; endless conveyers. HAUNI-WERKE KÍRBER & CO. K.G. 6 July, 1967 [26 July, 1966], No. 33596/66. Headings B8A and B8C. [Also in Division B4] Apparatus for attaching tear strips to a wrapper web includes cutter blades for severing the strips from a web, only one blade being movable in the cutting direction. This blade acts as a carrier for the strip to attach it to the wrapper web or pass it to a conveyer which transports it to the wrapper web and, during the transfer, moves at substantially the same speed and in the same direction as the web or conveyer. In one embodiment, the wrapper web 1 passes continuously over an adhesive applicator 6 and beneath a heated bar 43. The tear web 8, also moving continuously, is fed by rollers 13, 14 between curved plates 19, Fig. 5, and over a stationary bar 17. A cutter blade 16, pivoted and spring-biased for movement transverse to the cutting direction, co-operates with a blade 18 movable in a closed path by pins 24, 26 on rotating discs 25, 27. The blade 18 has suction apertures 28 in its upper surface and when it rises to sever a strip, the latter is held in place until pressed against the adhesive on the wrapper web travelling above. The suction is then released and air pressure applied to free the strip. The bar 43 dries the adhesive. The tear web accumulates between the plates 19 until free to advance again. In another embodiment, Fig. 3 (not shown), the arrangement described above is reversed, the cutter being above the wrapper web. In a further embodiment, a perforated continuously moving belt is sited above the cutter with the wrapper web passing along the upper run of the belt, Fig. 4 (not shown). A suction box enables the belt to pick the strips off the moving cutter blade. Adhesive is applied to the strips while held by the belt.

Title: Improvements relating to Fingerprint Identification
Inventor: ACKROYD JOHN
IPC: G06V10/88
Filed: 1966-07-27
Abstract: 1,188,302. Recognizing finger-prints. BRITISH AIRCRAFT CORP Ltd. 24 July, 1967 [27 July, 1966], No. 33740/66. Heading G4R. [Also in Division G2] In finger-print identification apparatus, known finger-prints in an array are correlated optically with the Fourier transform of an unknown print to produce light spots each with an intensity depending on the correlation between the unknown print and a known print, the co-ordinates in the array of a known print producing a spot exceeding a predetermined intensity being read out. Coherent light from a laser source is transmitted through a slide holding an array of known finger-prints, and then a Fourier-transforming lens, on to a hologram of the unknown print, a reference beam split from the original laser light also being directed on to the hologram. The hologram output light is imaged by an optical correlator on to a vidicon which scans the correlation light spots. The correlator or the array of known prints is rotatable to allow for non-standard orientation of the unknown print or print fragment. The amplitudes of the spots are digitized and fed with the values of their position co-ordinates to a computer which stores the data for spots of above a certain amplitude for subsequent print-out. A plurality of scans could be made with successively larger or smaller thresholds until a suitable number of spots above the threshold is found. The scanning could be done using masks movable in the X and Y directions over the slide of known prints. A series of slides of known prints can be tried in turn automatically until a match is found. By using the technique of volume holography, a plurality of arrays of known prints can be stored on a single slide, the slide being rotated to access successive arrays. The distance between the Fourier-transforming lens and the hologram of the unknown print may be varied to compensate for different sizes of unknown print. The hologram is formed by replacing the slide of known prints by a transparency of the unknown print and putting a photographic plate where the hologram will eventually go for print identification. The reference beam could be dispensed with throughout in which case a mere Fourier transform of the unknown print is produced and used instead of a hologram. The reference beam, when used, also has the function of normalizing the output against changes in source brightness.

The moving contact 25 is normally held engaged with fixed contacts 23, 24 by interengaging parts 17. 18 which may be released on overload to allow the contacts to open, the part 17 being carried by a cover 11 which is movable manually to open the contacts without tripping. The contact 25 has an extension 26 secured by a bolt 27 to a bimetal strip 15 which is pivoted at 12 and biased clockwise, Figs. 1 and 3, by a spring 35 secured to the cover at one end. The bolt 27 carries a chamfered nut 18 which co-operates with a recess in a latch arm 17 of a latch 16 pivoted at 16a on the cover. The latch has an armature 20 which in the closed position, Fig. 1, is near a magnet 21 formed by a strap bent round conductor 22, so that with a short circuit, the armature is attracted to disengage parts 17, 18. With a prolonged overload, bimetal 15 deflects to the left, Fig. 4, to disengage these parts. In either event, the spring 35 separates the contacts and the parts take up the Fig. 3 position in which an arm 15a carrying the bimetal abuts a screw 31 on the base 10. The parts 17, 18 are reset by moving the cover outwards to the Fig. 5 position to an extent allowed by the movement of a slot 41 therein past the screw 31. The contacts are reclosed by returning the cover to the Fig. 1 position where the cover is held by a spring 32 on the base engaging a shoulder 34 on the cover. The contacts may be manually opened by moving the cover to the Fig. 5 position. The air gap between parts 20, 21 may be adjusted and the nut 18 may be adjusted along bolt 27. A number of breakers may be clipped side-byside on to a common support-bar 1, Figs. 6, 7 (not shown). The latch 16 carries the word " TRIP " which becomes visible through a window 39 in the Fig. 3 position, and the base carries the word " ON " which is visible in the slot 41 in the positions of Figs. 1 and 3, but is invisible in the Fig. 5 position. Specification 860,785 is referred to.

Aeroplanes; aerial machines coupled in pairs or trains; cars and cabins; planes, arrangement and construction of.-An aeroplane, which may have a span of more than 3 times its length, has a constant surface load throughout its supporting plane t, the live and dead loads being so arranged that a constituent part of the plane carries a definite part of the load, the stresses being thereby reduced. At points of least stress, rigid or slightly resilient joints may be provided as indicated at i to facilitate construction or to provide resiliency on landing, the portions between the joints being designed as individual machines; an increase in dimensions of the machine takes place in the transverse direction, the longitudinal length of the machine bearing a constant relation to the chord of the plane. The surface of the plane and the spars are united to form a box girder in which the freight may be moved transversely of the machine. The invention may also be applied to biplanes or multiplanes. A list of the dimensions of existing large aeroplanes is given which shows that the maximum ratio of span to length is 2.22. Floats, wheels, and skids are evenly distributed over the supporting surface and may be differentially connected together by angle levers w, and rods l. Propelling; steering, balancing, and regulafing altitude.- Propellers p, driven by motors m, which may be controlled from a central position, and elevators h mounted on supports r, are evenly distributed over the supporting plane, and may be as shown, or in line with one another on opposite sides of the main plane, and the propellers may then be alternately in front of and behind the main plane. Balancers q and rudders u are provided at the tips of the planes, but may also be evenly distributed over the plane and their dimensions may be in proportion to their distances from the centre of the machine. The motors near the tips should be capable of greater power for guiding the machine in a curved path, and for this purpose their controls may be coupled with the rudder controls. Central controls may operate the steering apparatus by means of compressed air or electricity.

Abstract: 1,002,492. Tractor power lift mechanisms. DAVID BROWN TRACTORS Ltd. Aug. 26, 1963 [Sept. 6, 1962], No. 34112/62. Heading AlP. The tractor power lift mechanism described in Specification 871,053 is arranged so that the Bowden cable 44, 46, which transmits signals from the upper link 30 to the control valve 35 for draft control, can be disconnected from the upper link and connected to an arm 100 whereby signals are transmitted to the control valve to keep the implement in a constant position with regard to the tractor. In the position shown in Fig. 2, if the rock shaft 26 turns, the Bowden cable 44, 46 is operated by arm 100 to operate valve 35 so that pressure fluid in the ram cylinder 12 is controlled to restore the rock shaft and therefore the implement to its position set by hand lever 49. In an embodiment the Bowden cable is connected to a yoke which is connected by Bowden cables with each of the lower draft links via pivoted arms whereby movements in the lower draft links are transmitted to the valve 35. In modifications draft control can be effected by connecting the cable 44, 46 to a governor driven by the tractor engine and the cable 44, 46 can be replaced by a flexible electric cable connected to a strain gauge or variable resistance, the slide valve 35 then being operated by a solenoid or the cable 44, 46 may be replaced by a flexible hydraulic linkage consisting of a column of oil movable in a flexible conduit, the ends of the conduit being connectible to small single acting hydraulic cylinders on the respective parts of the mechanism. In a further modification for positional control the cable 44, 46 is connected to a groundengaging member movably mounted on the implement. Reference has been directed by the Comptroller to Specification 871,053.

[Also in Group XIII] In an apparatus for heating a beverage or other liquid in a container 35 by injection of steam, the steam is generated in a pressurized water reservoir 30 by an electric heater 46 the circuit of which includes a cut-out switch 47 adapted to open at a preset pressure in the reservoir, a solenoid operated steam valve 32 for controlling the passage of steam from the reservoir to the steam nozzle 34 and a time switch 41 (Fig. 2, not shown) to close the steam valve after a predetermined time interval. The apparatus shown includes a main on-off switch 48 and in one mode of operation, the switch 48 is first closed and then operation of the time switch is initiated by a cam 36 on pulling down the handle 37 to bring the steam nozzle into the liquid container 35. Alternatively the operation of the time switch may be delayed by operating the main switch only after the steam nozzle has been lowered into the container 35. A spring-operated catch 42 co-operates with a latch 43 on the steam injector tube to hold it in its lowered position. At the end of the steam cycle the time switch operates a solenoid to move the catch 42, thereby releasing the cam and allowing the steam injector to be pulled upwardly by the return-spring 52.
