Title: Improvements in or relating to packages
IPC: B65D75/08
Filed: 1946-11-06
Abstract: 618,629. Wrapping-up. ROSE, A. G., GILBERT, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 6, 1946, No. 32946. [Class 94 (i)] In a package of the kind in which a wrapper of paper, film, foil, or like wrapping material is first folded about one end and two faces in the form of a U with portions extending from the sides and the other end of an article sufficiently to form side and end flaps to complete the wrapping of the article, the last folded side flaps are folded right over the adjacent sides of the article and partially over the adjacent face of the article. The extending portion may be folded on to the adjacent end to complete the package and the package completed by the sealing of the lastfolded end flap, although each fold may be sealed as formed. With thermoplastic material the sealing may be effected by means of heat and pressure. The packages so formed may be wrapped in one or more outer wrappings. In the form shown, to form a package with two wrappers, articles 16, viz. cakes of soap, are fed along a folding channel composed of a platform 17 and a guide plate 18 and engage a wrapper 19 to cause it to pass into the form of a U. In the channel tucking elements 27 cause the portion 26 of the wrapper to fold on to the end faces 28 of the article as in Fig. 2. The upper side flaps 29 by being passed through slots 32 are folded on to the end faces 28. On passing through slots 33 which extend into the guide plate 18 the lower side flaps 31 are caused to fold firstly as in Fig. 4 and then as in Fig. 5. The article 16 is now transferred to a pocket 37 of a pocket wheel 38 by a pair of inwardly movable tucking elements 39, which firstly form tucks on the rear end 36 as in Fig. 6, an outer wrapper 44 being then engaged, the article and wrapper 44 then moving together into the pocket 37 the wrapper 44 being folded as in Fig. 4. On insertion of the article 16 in the pocket 37 the tucking elements 39 move lower end flap 43. The pocket wheel 38 is rotated to carry the article to a further folding station whereby the portion 45 of the wrapper 44 and the upper end flap 42 of the inner wrapper are folded as in Fig. 8 by a member 46. At the next station a side 47 of the pocket 37 is opened and a tucking member 48 tucks in the wrapper 44 to enclose the lower face as in Fig. 9. The tucking member 48 is withdrawn, the movable side 47 closed, and the wheel 38 rotated to carry the article through an idle station to a transfer station where transfer members 49 having tucking members 53 engage an end face of the article to transfer it into a channel having a platform 51 and an upper guide 52. The members 53 and 54 form side tucks as in Fig. 10. In conveying the article through the channel the lower flaps 56 pass through slots 57 to be folded on to the side faces, and then come into contact with gumming wheels 58 on their outside, and finally the upper flaps 56 are passed through slots 59 and so to overlie the folded lower flaps 56 to which they are gummed, and the completed package is then discharged.

Title: Method of dynamic weighing
IPC: G01G19/04
Filed: 1975-07-25
Abstract: 1495277 Weighing electrically W & T AVERY Ltd 25 July 1975 [26 July 1974] 33032/74 Heading G1N(A) A method of dynamic weighing substantially as described in Specification 1123211 further comprises monitoring the value of a pre-selected parameter influencing the accuracy of weighing and varying the function f(t) and/or the duration T of the weighing period in dependence on the value  said parameter. The function f(t), which may comprise a series of steps corresponding to different sampling rates, may have sections A, B, C successively eliminated as the speed of rolling stock passing over a weighbridge increases. This may be achieved by programming of the number of samples counter described in Specification 1123211. This method decreases the number of samples N taken during the weighing period so that the result of integration must be divided by N to obtain the static weight. Alternatively N may be maintained constant and the clockpulse generator (1123211) arranged to increase pulse frequency with speed, or the pulse rate divider (1123211) may be programmable with any one of a number of different functions f 1 (t), f 2 (t) etc. In applications where the natural frequency of the weighbridge provides the dominant error signal an instruction signal related to the natural frequency determines which of functions f 1 (t), f 2 (t) etc. is multiplied with the weight signal in filter 18; each function providing high attenuation at a different frequency. The functions may be stored in digital read-only memory devices ROM or may be generated by a function generator (30), Fig. 8 (not shown) in the form of a cosine series the coefficients of which are provided from a store (32) governed by the instruction signal. The systems of Figs. 7 (and 8) may also be used for other parameters such as speed. In a further embodiment the weight determined using a first function g(t) is used to calculate the natural frequency. If g(t) does not provide high attenuation the measurement is repeated using a second function f 1 (t). The new weight value is again used to calculate natural frequency and if necessary a third function f2(t) is used. Thus by a process of iteration a function providing high attenuation at the true natural frequency is arrived at.

Title: Manufacture of pure hexachlorocyclopentadiene
IPC: C07C17/38
Filed: 1957-10-24
Abstract: Crude liquid hexachloro-cyclopentadiene or a solution of it is cooled to such a temperature that crystalline hexachlorocyclopentadiene separates from the crude oily substance or from the solution and is obtained in a pure form.  If a very impure crude substance is treated it may be necessary to repeat the crystallisation process to obtain a product of desired purity. The temperature to which the crude material is cooled should be between that at which the hexachlorocyclopentadiene melts in the medium concerned and about -70 DEG C.  In general the upper limit is -10 DEG C.  As solvent there may be used isopropanol, n-propanol, or acetone, or a mixture of these.  Somewhat less suitable are petroleum ether and benzine.  If no solvent is present during the crystallisation process, the product must subsequently be washed with a cooled solvent.  The crude hexachlorocyclopentadiene may be in the form of a solution obtained by chlorination with alkali hypochlorite of cyclopentadiene in the presence of a solvent, which is immiscible or sparingly miscible with water, and separation from the aqueous phase.

Filed: 1971-07-17
Abstract: 1395155 Photo-electric inspection of hollow bodies A L DUNN & CO Ltd 14 July 1972 [17 July 1971] 33665/71 Heading G1A The interior of a hollow body is inspected by locating an opening into the interior of the body in register with a detector arranged in a support surface of the body and admitting light into the interior. The presence of moulding or core sand within a manifold casting is detected by seating the casting 4 on a rubber pad 3 in a locating plate 2 so that four light dependent resistors LDR are located at the ports. A light source 5 is then energized and inserted into the inlet port 41 of the manifold. The LDRs are arranged in individual switching circuits with indicator lamps LPI and the outputs of the circuits are combined to operate a stamping or punching mechanism 10 which marks satisfactory units. When a start switch SW 1 is operated relay RLA is energized and latches, and the circuits are powered. The LDRs are unilluminated and have a high resistance and the lamps LPI are all illuminated. The light source (S) is then inserted and provided a passage is clear of sand the associated LDR is changed to its low resistance state and the corresponding lamp LPI is extinguished. If all four passages are clear a second relay RLB is energized and punch 10 operates to mark the casting. Operation of punch 10 also opens switch SW3 to unlatch relay RLA and reset the circuit for the next test. If any passage is blocked the associated lamp LPI remains illuminated and the punch 10 does not operate. In this case the circuit is reset by operation of switch SW20. An audible fault indication may be provided, other types of detectors may be used and the illumination source may emit I.R. radiation.
