Title: Process for preparing halogenated and halosulfonated polymers
IPC: C08F10/00
Filed: 1958-12-15
Abstract: A halogenated olefin polymer is prepared by polymerizing the olefin using an organometallic catalyst in the presence of a halogenated solvent and then treating the polymer with a halogenation reagent in the presence of the halogenated solvent. Specified olefins are ethylene, propylene, 1-butene, 1-hexene, 1-octene, ethylene-propylene and ethylene -1-butene mixtures.  By organo metallic catalyst is meant an organometal compound, a metal or a metal hydride together with a Group IV, V, VI or VIII metal compound.  A very large number of specified organo-metallic catalysts include the aluminium alkyls, the aluminium hydrides, and the aluminium alkyl halides, as well as those of other Group I-III metals, together with the oxides, hydrides, halides, oxyhalides, alcoholates and organic acid salts of titanium, zirconium, chromium thorium, molybdenum, vanadium, iridium and platinum.  A third catalyst component, being an organic or metal halide e.g. ethyl bromide, 1-brombenzene, cyclohexyl chloride and aluminium chloride, or a halogen, a hydrogen halide, an organo phosphorus containing compound, a peroxide, a metal alkoxide, a carbide or an acetylenic compound may also be present.  Carbon tetrachloride and tetrachloroethane are the preferred halogenated solvents and elemental chlorine the preferred halogenation agent. The halogenated polymer may be sulphonated, sulphonating agents being sulphur dioxide, chlorosulphonic acid and sulphonyl chloride. Apparatus for carrying out the process is described.

Title: Cold storage unit
IPC: F25D3/10
Filed: 1961-11-15
Abstract: 960,651. Cooling bulls' semen etc.; coldretaining vessels. J. R. PRENTICE, [trading as AMERICA BREEDERS SERVICE]. Nov. 15, 1961 [Dec. 5, 1960], No. 40808/61. Headings F4H and F4U. [Also in Division A2] A cold-storage unit, e.g. for storage of canisters containing ampules of bulls' semen or other biological substances, comprises a container having an internal compartment communicating with the outside through a relatively narrow opening in the top of the container, and a support framework fixed in the compartment comprising storage slots which are accessible through the opening for insertion and withdrawal of canisters or other objects to be stored and extend outwards from and on opposite sides of a space directly beneath the opening. As shown, the container comprises a vacuum vessel 10, Fig. 1, the vacuum space 14 being at least partially filled with heat insulating material. The opening in the neck 21 is normally closed by a loose-fitting plug (not shown) and covered by a metal guard cap 18. The support framework comprises support and guide plates 22 and 23 connected by vanes 24. The plates 22, 23 have aligned slots 28, 32, Fig. 7, extending radially from an unobstructed central area, each slot being of sufficient length to support two canisters 12. Segments 29 of plate 22 are downwardly inclined so that the canisters tend to slide towards the centre and are held by stops 31; the bottoms of the inner canisters abut against member 26 in the bottom of the vessel so that the canisters are positioned at right angles to the plane of the segments. A canister is inserted or withdrawn by a handle 13, Figs. 1 and 11, including a lip 38 which engages in an annular slot 58, Fig. 8, formed in the support shoulder 57 of the canister, and a canister which has become jammed in the outer position can be retrieved by hook 42 on auxiliary tool 40, Fig. 13. The canisters may be kept cool by partially filling the vessel with liquid nitrogen. In a modification, Fig. 15, two of the vertical vanes 46 are replaced by foraminous walls 43, 44 which with a special " gate " canister 48, Fig. 16, define a pocket or bin for dry ice, the canisters then being cooled by a liquid refrigerant, e.g. alcohol, flowing over the dry ice and through the remainder of the vessel. In a further modification (Fig. 17, not shown), a dry ice pocket is formed by walls extending downward from the edges of a single segment 29. Alternatively, the dry ice may be contained in a canister. Various modifications of the support framework are mentioned, e.g. the segments 29 may be replaced by narrow inclined tracks and the slots may be disposed along lines other than radii. Reference is made to storing substances other than semen, e.g. biological or physiological specimens.

Title: Measuring the sharpness of images
IPC: G02B27/40
Filed: 1974-09-25
Abstract: 1480289 Photo-electric measurement of image sharpness RESEARCH CORP 25 Sept 1974 [17 Jan 1974] 41675/74 Heading G1A [Also in Division G2]  To detect the sharpness of an image it is projected on to a transducer comprising a medium whose electrical properties vary with the incident image and also with a strain wave in the medium, and the modulation of the electrical properties at the strain wave frequency is observed. The basic transducer is described in Specification 1445119 (see Division H3-5). In Fig. 1 the medium is a CdS film 22 on a quartz substrate 20; a generator 26 establishes a strain wave 28 on the substrate, the wavelength being greater than the desired sharpness resolution but less than the size of the image projected from source 44. The wave frequency is for example 3-8 MHz. Contacts 24a, 24b allow the film resistance to be monitored by applying a constant bias voltage to it from supply 32. The D.C. current measured at 34 corresponds to a conventional measure of image intensity, while the modulation at the strain wave frequency measured at 42 is a function of image sharpness. In variations of this basic arrangement the film electrodes may be inter-digitated or curved, and the film may be thicker at its central region than elsewhere Figs. 8, 9 (not shown); these latter two arrangements allow the sharpness of images of low intensity or of low contrast to be detected. Two dimensional measurements can be made by using two generators whose waves intersect at the film, or by using two films angled with respect to one another, Figs. 7, 13 (not shown). It is also possible to replace the film with a tunnel barrier formed by a thin oxide layer between two aluminium films on a glass substrate, Fig. 10 (not shown); the film may also be replaced by a degenerate semi-conductor or a metal, or a photoemissive cathode and a collector plate. In all these arrangements the detected modulation is a maximum when the image is at its sharpest, Figs. 5, 6 (not shown). This can be used to automatically focus a slide projector, either by projecting the image on to a screen behind which is a focusing system and a Fig. 1 detector, Figs. 3, 4 (not shown), or by having a beamsplitter in the projector such that the image on the screen is reflected back into the projector and thence via the splitter to a Fig. 1 detector, Fig. 12 (not shown). The modulation can also be used to focus an SLR camera as in Fig. 11, where the SLR mirror directs the image on to the viewing screen 72 which carries a CdS film 22 and receives a strain wave from 26; a meter 34 acts as a conventional exposure meter while the tuned detector output can be displayed at 81 for manual focusing or can drive a lens setting motor 84.

A method of closing, squaring and sealing a box having a body with a hinged cover panel and cover flaps comprises advancing the box with one body side wall leading, folding the cover panel and trailing cover side flap into closing positions and moving a transport element against the trailing cover side flap and so displace the cover panel until it is in a squared position with respect to the box body, the cover front and side flaps being subsequently adhesively sealed to the box walls. The filled box is advanced by conveyers 24, 25 and lugs 26, 27 beneath rails 28, 29 which close the cover panel 16 with an amount M of misalignment with the box body due to friction between the rails 28, 29 and the cover panel 16 to the position B4 where, with the cover panel 16 held closed by an extension 30 of the rail 28, a rotating element 31 folds down the trailing cover side flap 18 which is then engaged by a lug 39 on a conveyer 40 moving faster than the conveyers 24, 25. The lug 39 corrects the misalignment and moves the box through the positions B5, B6 where adhesive is applied and the front cover flap folded down and sealed on to the box front wall. Finally, the box is rotated through 90 degrees by means not described and transferred to a conveyer 43 for the cover side flaps to be glued, folded and sealed to the box side walls. Instead of adhesive applying devices heaters may be employed and the boxes precoated with thermoplastic material. Specification 914,237 is referred to.
