Title: Improvements in or relating to cutting devices
IPC: A24C5/28
Filed: 1952-12-15
Abstract: 735,774. Sharpening machine cutters in situ. MOLINS, b. W., and MOLINS MACHINE CO., Ltd. Nov. 25, 1953 [Dec. 15, 1952], No. 31764/52. Class 60. A rotary cut-off device, e.g. for severing the continuous rod in cigarette-making machines, has a curved-edged blade 1 held by a clamp 2 to a carrier 3 which is pivoted to the driving shaft 4. A fork 6 is also pivoted to the carrier and joined to a shaft 16 adjustably inclined at an angle to the shaft 4. As the shaft 4 rotates the blade 1 is carried round and passing through a slot in a ledger cuts through the rod which is supported by the ledger tubes. The combined effects of the two shafts and the fork 6 which constitutes part of a universal joint causes the blade to make complete rotations and at the same time to be translated substantially parallel to the axis of the shaft 4 so that it moves at the same speed as the rod during the time it is actually cutting through the rod. A grinding disc 8 supported by an arm 14 is so arranged that the blade 1 sweeps over it during every revolution and is thus kept sharp. To prevent the flexible blade 1 bending away from the grinder, a bent plate 9 is provided, one side of which is in contact with the blade at or near its cutting edge on the side opposite that which engages the grinder and supports the blade against bending..This support is pivoted at 10 and to its pivot is attached a cam lever 11 having at its free end a cam follower 15 which runs in a cam groove 12 formed in a plate 13 ; this plate is fixed to the arm 14 mounted on the housing 5 of the shaft 16 so that when the angle of this shaft is altered to increase or decrease the amount of translation, the cam is moved with it. The shaft of the cam track is such that as the plate 9 approaches the ledger it is caused to rotate on its pivot 10 so that its rear end moves inward from the edge of the blade, the plate thus passing by the ledger without contacting it. Specifications 324,379, [Class 130], and 423,503, [Group VI], are referred to.

Title: Improvements relating to electric switchgear
IPC: H02B11/00
Filed: 1926-12-16
Abstract: 283,714. British Thomson-Houston Co., Ltd., and Heath, H. C. Dec. 16, 1926. Sliding switch-carriage arrangements. - In draw-out switchgear with duplicate sets of contacts arranged to be selectively interconnected by a single set of removable plugging devices carried by the. movable switchgear member, the inward movement of this member is always arrested during its motion toward the fixed switchgear structure, and this movement can only be completed if the plugging devices have been inserted so as to prevent simultaneous establishment of alternative connections. As shown in Fig. 1, the double-ended plug members 24 are inserted in the upper sockets 23 corresponding to the upper set of bus-bars 17. The inward movement of the truck 14 is arrested bv a roller 33 carried bv a sliding bolt 30 engaging a stop 36 in the fixed runway 34. To complete the movement of the truck the roller 33 has to be raised through the aperture 35 at the end of the groove 34 bv means of toggle mechanism operated bv the handle 31, this mechanism consisting of a link 29 and one arm of a bell-crank lever 27 pivoted at 28 and provided with centralising springs 39. The free arm of the bell-crank 27 carries a transversely-extending feeler 26 which can only be swung in one or other of its directions to free the bolt 30 if the plug members are inserted only into one or other sets of sockets. As shown the lower sockets are free from plugs so that the feeler 26 may be swung to the position shown, freeing the truck so that it may complete its inward movement. In a modification (Fig. 2, not shown), instead of arranging a guideway for the roller on the looking bolt a suitable guideway for the feeler bar 26 is provided, and in a further modification of this arrangement (Figs. 3 and 4, not shown) the centralising springs may be substituted by a spring biassed link carrying the bell-crank lever, which is arranged to hold the bolt automatically in its locked position after it is released by operation of the handle 31 when the movable switchgear portion is in its intermediate arrested position. In place of the double-ended removable plugs carried by the truck member, double-tended removable socket members may, alternatively, be employed.
Patent GB-465960-A (GB)
Title: Manufacture of ketones of polycyclic hydroaromatic compounds
IPC: C07J75/00
Filed: 1935-11-18
Abstract: Acids of the general formula <FORM:0465960/IV/1> where R stands for the cyclopentanopolyhydrophenanthrene nucleus are converted into ketones of the general formula <FORM:0465960/IV/2> by subjecting the acids first to a decomposition by the method of Curtius followed by oxidation of the amines so produced to the required ketone.  The process comprises the following steps: (1) Formation of the acid halide particularly the acid chloride; (2) Formation of the acid azide by the action of an alkali azide particularly sodium azide; (3) Formation of the isocyanate by the action of heat on the azide; (4) Formation of the amine by hydrolysis with a strong mineral acid; (5) Oxidation of the amine by sodium hypochlorite.  Instead of step (5) the amine may be converted into the corresponding alcohol with sodium nitrite and this oxidized to the ketone with chromic acid or potassium permanganate.  Any double bonds in the ring system may be protected by the addition of halogen, which is removed from the final product.  In examples: (1) acetoxy-bis-norcholenic acid is converted to the acid chloride by the action of thionyl chloride and sodium azide added in acetone solution.  The azide is separated, dissolved in toluene, and heated to give the isocyanate.  The isocyanate is converted into the amine either by heating with glacial acetic acid and acetic anhydride, or by stirring vigorously a benzene solution of the isocyanate with a 60 per cent aqueous solution of sulphuric acid. The acetoxy-ter-norcholenylamine so produced is treated with sodium nitrite and sulphuric acid.  Two products are obtained which are (a) the alcohol expected to be produced by the reaction of the amine with nitrite, and (b) the hydrocarbon obtained simultaneously by elimination of water.  These are separated and the alcohol after protecting the nuclear double bond is oxidized to progesterone by chromic acid; (2) Acetoxy - bis - norcholenic acid is converted into the corresponding amine via the acid chloride, azide and isocyanate as described in example (1).  The amine is then oxidized directly with sodium hypochlorite to pregnenol-(3) one-(20).  An alternative treatment of the amine is to oxidize it in glacial acetic acid solution with chromic acid, after protection of the nuclear double bond by halogen.  After the oxidation the halogen is removed by zinc dust, there is obtained 3-oxo-ter-norcholenylamine.  This oxo-amine is then oxidized with hypochlorous acid and the reaction product dehalogenated with either pyridine or silver nitrate to give pregnanol-(3)-one-(20), which on oxidation with chromic acid gives pregnendione.

Abstract: 1517466 Cattle yokes SUEVIA HAIGES KG 4 Aug 1976 [14 Aug 1975 19 May 1976] 32499/76 Heading AIM [Also in Division A5] An automatically closing yoke for-retaining an animal's head comprises a frame and at least one lever pivoted intermediate its ends, the arrangement providing an aperture through which an animal can put its head, the neck of the animal engaging the lower portion of the lever which is thereby pivoted to a position, in which it is locked, so reducing the aperture that the animal cannot withdraw its head. In one embodiment a lever 15, 16 is pivoted at 14 to a limb 13 of a frame 11 which is connected by chains 25, 26, 29 to a cattle stall. In the dotted line position of the lever an animal can put its head through an aperture 10 to reach a manger 30, and its neck contacts arm 15 and pivots the lever to its full line position. The upper arm 16 has a bifurcated end 18 carrying a pawl 22 co-operating with ratchet teeth 19, 21 formed on a horizontal part 17 of the frame. The lever 15, 16 is thus retained in its closed position trapping the animal's head. In order to release the animal a shaft 27 is rotated; the shaft has an arm 32 connected by a cord 31 to the pawl, and rotation of the shaft raises the pawl and pulls lever 15, 16 towards its open position. The lever is biassed to its fully open position by the weight of arm 16 which exceeds that of arm 15. As shown the limb 13 of the frame is shorter than that of the co-operating limb 12, but limb 13 could be extended by a vertical portion; in another embodiment the arrangement is symmetrical, both limbs 12, 13 carrying a locking lever. Instead of a rotatable shaft to release the pawls an axially slidable member can be provided.
