Title: Improvements in and relating to sleeping bags
IPC: A47G9/08
Filed: 1933-11-17
Abstract: 419,689. Sleeping bags. WALLIN, E. H., 33, Tingsgatan, Arvika, Sweden. Nov. 17, 1933, No. 32141. Convention date, Nov. 17, 1932. [Class 133.] A sleeping bag open at the end only comprises an outer bag 1, preferably of impregnated fabric, and an inner bag 2 so arranged therein that interspaces 3 extending across the full width of the bag are provided above and below it for the reception of straw or other heatinsulating material. The two bags may be afforded by stitching together along the edges four superposed layers of fabric 4-7, Fig. 1, or each bag may consist of tubular woven fabric, Fig. 4, or again a tubular woven inner bag may be encased in outer layers of fabric. The inner bag may be shorter than the outer one, affording a space between them at the closed end. In the construction shown in Fig. 4 the inner and outer bags are releasably connected together by a cord 18 being passed from the exterior through holes 16 and threaded through loops 17 of a second cord attached to the inner bag. Specification 398,700 is referred to. The Specification as open to inspection under Sect. 91 describes forms in which both the inner and outer bags have longitudinal openings closable by sliding clasp fasteners, one such form, shown in Fig. 7 (Cancelled), being provided with means for attachment to a disjointable frame 20 to serve as a stretcher.

Patent GB-896778-A (GB)
Title: Two speed hub transmission for velocipedes and the like
IPC: B62M11/14
Filed: 1960-09-19
Abstract: 896,778. Variable-speed gear. BENDIX CORPORATION. Sept. 19, 1960 [Oct. 5, 1959], No. 32172/60. Class 80 (2). [Also in Group XXXI] A two-speed gear and a brake for velocipedes are both operated by back-pedalling. A driving sprocket 14 is fast with a screw-shaft 8 having a clutch-nut 35 with facial teeth 36 engageable with teeth 27 of a driven clutch member 22 which is splined to a hub 11 and located axially by a stop 24. A low-speed screw-shaft 7 is driven through planetary reduction gearing from the sprocket 24 and has a clutch nut 25 having dog-teeth 26 engageable with the teeth of the driven clutch member for low gear. A ring 41 frictionally engages both clutch nuts, and a retarder ring 37 frictionally engages a non-rotary brake-ring 31 and has arms 39 engaged in openings 40 in the low-speed clutch nut 25. Balking means for selectively preventing engagement of the high-speed clutch 35, 22 comprises a sleeve 46 fast with the clutch nut 35 and having spring arms 49 frictionally engaging an indexing and blocking ring 51 which is swivelled on the high-speed screw-shaft 8. The blocking-ring 51 is provided with spring pawl members 53 co-operating with ratchet teeth 55 at the bottom of a groove in the screwshaft 8, thereby providing a ratcheting swivel connection between the shaft and the ring permitting backward rotation only of the blocking ring with respect to the shaft. The blocking ring has blocking lugs 56 which are alternatively disposed in the path of the arms 49 of the sleeve 36 and in the spaces between the arms as the ring 51 is indexed step-by-step on the shaft 8. In operation and as shown in Fig. 1, the clutch members 35, 22 are engaged to give direct drive. On back-pedalling momentarily the screw-shaft 8 is reversed, but the blocking ring 51 does not reverse due to its frictional connection through arms 49 with the clutch nut 35 which is prevented from rotating by the retarders 41, 47. The pawl arms 53 of the blocking ring thus snap over one tooth, and on subsequent forward rotation of the sprocket 14 the blocking ring prevents engagement of the high-speed clutch and allows clutch members 25, 22 to engage to give low gear. Continued backward rotation of the sprocket 14 rotates the screw-shaft 7 to cause the low-speed clutch-nut 25 to engage the brake ring 31 and compress brake discs 32, 33 which are splined on the hub and a stationary anchor member 4. By design the amount of backward rotation to apply the brake may be sufficient to cause the pawl arms 53 to snap over two ratchet teeth and ensure that on subsequent forward rotation the hub is driven in the last selected gear ratio.

Title: Oxidation of alcohols
IPC: C07C45/30
Filed: 1959-09-22
Abstract: A catalyst for oxidizing alcohols to carbonyl compounds at a pH below 4 comprises a halogen-containing compound of platinum, palladium, or rhodium.  The metal is present or is brought to the higher valency form in which it can exist.  The catalyst may be supported and may include an acid compound, e.g. hydrochloric acid, sulphuric acid, phosphoric acid, trifluoroacetic acid, alkyl or aryl sulphonic acids, halogen-substituted alkyl or aryl sulphonic acids or boron fluoride complexes.  When a non-halogen acid is added halogens may be added to the catalyst in the form of salts, e.g. ammonium, manganese or cupric chloride.  There may also be present compounds or ions of Group I, II, V, VI and VII metals, e.g. copper, silver, mercury, vanadium, chromium or manganese.  The catalyst may be regenerated by treatment with oxygen.  An activator may be present in the reaction or regeneration zone.  Suitable activators are, for example, hydrogen bromide, ozone, t-butyl peroxide, benzoyl peroxide, cumene hydro-peroxide, cumene, iodine, nitric oxide, quinone, aldehydes and isobutyro-azo-dinitrile.ALSO:Carbonyl compounds are produced by intimately contacting a feed comprising a C2 to C8 saturated alcohol in the liquid phase and at a pH below 4 with a catalyst comprising a halogen-containing compound of platinum, palladium or rhodium at a temperature in the range 50-300 DEG C., and recovering a saturated carbonyl compound having the same number of carbon atoms as the alcohol.  The metal is present in the higher valency form in which it exists.  The alcohol used as feed may be formed in situ from the corresponding olefine.  The preferred catalyst is chlorplatinic acid. The catalysts may include an acid compound, e.g. hydrochloric acid, sulphuric acid, phosphoric acid, trifluoroacetic acid, alkyl or aryl sulphonic acid, halogen substituted alkyl or aryl sulphonic acids or boron fluoride complexes.  When a non-halogen acid is used halogens may be added in the form of salts, e.g. ammonium, manganese or cupric chloride. There may also be present compounds or ions of Group I, II, V, VI and VII metals e.g. copper, silver, mercury, vanadium, chromium or manganese.  The catalyst may be used on a support.  An organic solvent, e.g. benzene, toluene, xylene, tetrahydrofuran, biphenyl, chlorobenzene, dichlorobenzene and alcohols such as C8-C20 alcohols or neopentyl alcohol, may be used.  If desired, oxygen may be passed into the reaction mixture and the catalyst may be regenerated by treatment with oxygen.  Chelating agents or catalyst activators may also be added to the mixture in the reaction zone or activators may be added to the catalyst in the regenerating zone.
