Title: Improvements in or relating to vehicle transmissions including an eddy current retarder
IPC: H02K49/04
Filed: 1966-09-02
Abstract: 1,147,373. Eddy-current brakes. LABAVIAS.G.E. 2 Sept., 1966 [16 Sept., 1965: 22 July, 1966], No. 39339/66. Heading H2A. In one embodiment of a vehicle transmission including an eddy-current retarder, the rotor of the retarder comprises a single plate 11, Fig. 1, secured to a transmission shaft 2, and the stator, secured to a differential gear casing 4, comprises at least one (in this case an even number of), windings 3, and a magnetic structure 6, 6 1 , 6 2 , associated with each winding so that at least two rings of magnetic poles, alternately north and south in each ring, are formed; the rotor presents two surfaces 1, 10, respectively, disposed symmetrically in relation to one another with respect to the central transverse plane of the retarder, each surface being aligned with the stator ring of poles, the surfaces preferably being connected to external cooling blades 12, and both being borne by the single plate 11. The axial recess provided by the left-hand blades 12 partly accommodates one of the universal joints 15 of the shaft; the right-hand blades overhang a bearing 14. The stator includes a non- magnetic support consisting of arms 8 1  with flanges 8 2 , and an annular disc 5. The casing 4 shown houses the differential gear but in a modification the stator is secured to the main gearbox casing, while the rotor is mounted on an extension of the main shaft 13. In a modification of this embodiment, double windings may be provided on either side of an intermediate magnetic disc. In Fig. 3 the stator comprises two windings 22 in the form of rings centred on the longitudinal axis of the transmission shaft and each is housed in an annular channel of a magnetic member 23 of which the outwardly-extending opening is partly closed by overlapping fingers 24 which form pole shoes. The necessary "two surfaces", above-mentioned, of the rotor, in this case take the form of cylindrical sleeves 20 connected to the central plate 11 by skirts 21. The sleeves and skirts are connected on the outside to cooling blades 12. In a modification, the two channels 23 may be mounted-back-to back and axially open opposite two rotor disc parts. The stator may include only a single winding, centred on its axis.
Patent GB-993139-A (GB)
Title: Stabilized vitamin compositions and a process for preparing them
IPC: A61K47/42
Filed: 1962-10-18
Abstract: A stable composition of vitamin in a gelatin-urea medium is obtained by blending gelatin, urea and water at 0 DEG  C. to 80 DEG  C. until a uniform dispersion is obtained, admixing said dispersion with said vitamin and homogenizing, if desired, the resulting mixture until a uniform emulsion is obtained.  (By the term "vitamin" used herein is meant any or all of the well-known oil-soluble vitamins and their vitamin-active, pharmaceutically-acceptable salts and esters, whether prepared synthetically or obtained from natural sources.)  The obtained emulsion may be dehydrated by heating at 40 DEG  C. to 100 DEG  C. under reduced pressure and the resulting solid reduced to any desired particle size.  Alternatively, the emulsion may be blended at 0 DEG  C. to 90 DEG  C. with an inert, adsorbent carrier until granules are obtained to form a free-flowing, water-dispersible, oxygen-stable, dry adsorbate of vitamin.  Suitable adsorbents include soy flour, corn flour, rice flour, wheat flour, gelatin, lactose, mannitol and diatomaceous earth.  In the preparation of the emulsion, it is preferable to remove the materials employed from contact with oxygen, and when it is desired to convert the emulsion to the dehydrated or adsorbate form it is advantageous to add a plasticizer to the emulsion, e.g. glucose, corn syrup, propylene glycol or honey. Bacteriostats, e.g. zinc sulphate; yeast and mould inhibitors, e.g. sorbic acid; antirancidity and chelating agents, e.g. citric acid; and anti-oxidants may also be added to the emulsion.  The dehydrated and adsorbed emulsions may be treated according to the method described in Specification 993,138 to render them insoluble in water and gastric juice but soluble in intestinal fluid.  This may be achieved by adding to the emulsion a substance such as formaldehyde, glyoxal, dihydroxy-acetone or acetaldehyde.  Specified vitamins for use in the invention are Vitamin A, Vitamin A palmitate, Vitamin A acetate and Vitamins D, E and K.  The stable vitamin preparations of the invention may be employed in the preparation of stable multi-vitamin compositions, e.g. by combining with water-soluble vitamins and minerals, or may be incorporated in foods and animal feeds.ALSO:In food or animal feed is incorporated a stable vitamin composition in which the vitamin is dispersed in a gelatin-urea medium.  ("Vitamin" is any or all of the oil-soluble vitamins and their vitamin-active, pharmaceutically-acceptable salts and esters, synthetic or from natural sources.  Specified are Vitamin A, Vitamin A palmitate, Vitamin A acetate and Vitamins D, E and K).  The compositions in emulsion form may be granulated by drying and comminuting or by mixing with a carrier such as a cereal flour, soy flour, lactose or diatomaceous earth.  A plasticizer for gelatin, e.g. glucose, corn syrup, honey or propylene glycol may be incorporated in the composition. Specification 993,138 is referred to.

Title: An apparatus for packaging articles in a package of a sealable material
IPC: B65B9/06
Filed: 1964-06-24
Abstract: 1,067,166. Packaging machines. SOAG MACHINE TOOLS Ltd. June 24, 1964 [June 24, 1963], No. 39840/63. Heading B8C. A packaging apparatus comprises means for folding a web of sealable wrapping material longitudinally, means for sealing the edges of the web to form a tube, means for introducing articles into the tube, a reciprocable drawing device with clamping means for advancing the tube, means for sealing and severing the tube transversely between the articles, leaving the cut edges sealed, a belt for supporting the packaged articles between the first sealing means and the discharge end of the apparatus, and rollers mounted on the drawing device and so arranged on the belt to form a recess therein to allow the lower jaw of the clamping means to move below the packaged article on the clamping means return movement. A web of heat-sealable packaging material is run off a supply roller 4, round guide and balancing rollers 5, 6, into a channel 8 and around an inner channel 11. The web is folded into a tube by lips 16 (Fig. 2, not shown), mounted on the channel 8. At one end of the channel 11 is a cover-plate 21 above which is a device 15 for sealing the margins 14 of the web. The articles are fed along a conveyer 2 to a feed-box 17, with openable bottom flaps 18 through which the articles are dropped, manually as shown, singly on to the channel 11. Each article is then engaged by the rear flap 30 of a pusher 12 which also has further flaps 28, 29. The pusher 12 reciprocates back and forth and after each forward stroke the flaps 28-30 are swung upwardly to ride over the top of the articles on the return travel, each flap then engaging the next rearward article. The articles are thus fed into the formed tube and to the reciprocating sealing and drawing device 10 where the tube is gripped transversely by jaws 19, 20 which form two seals between each pair of articles so that the packaged articles can be separated by severing between them. During the sealing process the package is drawn along and is supported on a belt 9 which may either be endless passing round rollers 26, 27 or may be fixed at its ends. The belt 9 has rollers 23, 24, 25 mounted on the device 10 forming a recess in the belt so that the lower jaw 20 can be lowered well away from the articles on the return travel of the device 10. If the belt is endless the reciprocation of the rollers moves the belt along, backward movement being prevented by a free-wheel clutch. If the belt is fixed the rollers 23, 24 and 25 slide backwards and forwards along the belt.

Solvent is recovered from dry-cleaning drum 2 by passing a stream of hot air through it, drawing the mixture of air and solvent vapour into blower 4 which feeds it into surface condenser 7 where most of the solvent is condensed, conducting the air and condensate to zone 9 where water (or other liquid) is sprayedin through nozzle 10, and returning the air to the drum 2 via heater 8 and shaft 12. The mixture of water and condensed solvent is withdrawn through pipe 18. Excessive drying of the goods in drum 2 is prevented by operating in the manner indicated. In Fig. 4, the water is sprayed from nozzle 10 in the direction of a fabric 16 made of textile threads or metal wires. The spraying-nozzle may be coupled with an hygrometer which sets the nozzle in operation when the moisture conditions in the drum 2 have dropped below a determined value.
