Patent GB-716099-A (GB)
Title: Improvements in the production of oximes
Filed: 1952-12-19
Abstract: Oximes are obtained from nitroalkanes or nitrocycloalkanes by treating aqueous solutions of their salts (especially alkali, alkaline earth or ammonium salts) with mineral acids at pH = 1.5 to 3.5, preferably in presence of salts, especially ammonium salts.  The oxime is liberated from the acid solution obtained by raising the pH to 4-5.  In examples, nitrocyclohexane, 2-nitropropane and other nitro compounds in solution as their salts, e.g. sodium salts, are treated with sulphuric or hydrochloric acid with ammonium or sodium sulphates at pH of 2 or 3, at room temperature, to give the corresponding oximes, together with fair quantities of the corresponding ketone in the case of cyclohexanone.  Other specified nitro-compounds include nitro-octanes, methyl-nitrocyclohexanes, and nitrocyclopentane. Other ammonium salts and cyclohexylammonium sulphate may be added.

Title: Improved automatically variable drive gear for fishing reels
IPC: F16H61/02
Filed: 1961-09-08
Abstract: 925,964. Change-speed gear; ratchet clutches; slip couplings. URFABRIKEN A.B. Sept. 8, 1961 [Sept. 30, 1960], No. 32411/61. Class 80 (2). A change-speed gear driving a fishing reel 2 and having ratio shifts effected automatically by changes in the tension of the wound line, comprises a driving shaft 9 rotated by a hand crank 23 to transmit torque through a friction slip coupling 17, 18 and a gear pair 7,5 at a relatively high ratio to the reel 2 when the tension in the line is small, increasing line tension causing the coupling to slip so that a previously overrunning ratchet pawl 31 mounted in an extension 32 of a second drive gear 8 engages teeth 30 on the periphery of the slip coupling for transmission of drive at a lower ratio through the gear 8 and a gear 6 to the reel. When the line tension is small and drive is transmitted through the gear pair 7, 5 to the reel 2, two leaf-spring arms 33 in light frictional engagement with opposite sides of the slip coupling 18 and carried by the ratchet pawl 31 hold the latter clear of the teeth 30 by virture of the over-running between the coupling and the gear 8. On increasing line tension causing drive to be transmitted at the low ratio through the gear pair 8, 6, a spring 29 carried by the gear 7 ratchets in-and-out of recesses 15 in a disc 16 carried by the shaft 9, to give an audible signal. If the load increases still further, so that the reel 2 ceases to rotate, the frequency of the signal produced increases. The discs comprising the slip coupling 17, 18 are compressed by a spring 22 adjustably biased on turning a star wheel 24 upon the threaded end of the driving shaft 9. A one-way detent 27 engages teeth 16 on the disc 15 to prevent reverse rotation of the driving shaft 9 when the line is pulled off the reel 2.

Abstract: 1,042,040. Gas holders. KINS DEVELOPMENT Ltd. Oct. 6, 1964 [Aug. 16, 1963], No. 32463/63. Heading F4X. In a gas holder in which a flexible sealing diaphragm 17 extends between the wall 10 of a tank and a piston 13 movable up and down within the tank, the gas confined by the seal 17 surrounds the piston 13 to a height H above its centre of gravity 14 sufficient for said piston to be self-stabilizing in any position of its travel. Preferably H is always greater than r/(#+4/#), where r is the radius of the piston. Further stabilization may be provided by a rod (not shown) extending downwards from the piston into a well (not shown) in the base of the gas holder. Guide wheels 24, 18, Figs. 2-4 (not shown), may be arranged in the well, and/or round the upper periphery 20 of the piston which may also bear a hinged skirt 25, Fig. 5 (not shown). Further guide wheels or sleds, which may be sensitive to the load thereon, may be arranged round the lower periphery of the piston. Balancing of the piston may be monitored by reflecting a light beam 27, Fig. 6 (not shown), from a mirror 28 on the piston and on to a photo-electric cell. Buffer means 32 serve to distribute evenly the weight of the piston when the holder is empty. The roof 11 may rest freely on the outer shell 10 and may be lifted by the piston over the upper part of its travel. The seal 17 may be formed of a fabric having oblique reinforcing threads to avoid the need for corrugating the outer wall of the piston. The piston and the shell may be of prestressed concrete and may hold gas pressures up to 300 ins. water

Abstract: In impregnating stator windings with a mixture of resin and liquid hardener the stator is mounted on a rotary and pivotable support means, is preheated to a predetermined temperature, is trickle coated with said mixture and is thermically cured; the preheating of the stator winding and the curing are controlled electrically in a self monitoring manner in that electrical impulses control the heating of the stator with a measurement process by a Wheatstone bridge to monitor the actual temperature of the stator at any time with the support means pivoted out of a horizontal position; pumps for delivering the resin and hardener to a mixing chamber are controlled according to a function of the heating current flux for preheating the stator; a discharge valve of the mixing chamber is controlled by electrical impulses according to the desired temperature of the stator at zero bridge reading and the commencement of the curing process is initiated as a function of the discharge of the mixing chamber by an electrical impulse triggered by the latter when the stator support means are pivoted back into a horizontal position.  In the apparatus shown there are two work stations A and B independent of each other and a common trickle coating device movable from one to the other.  At each station there are a number of work positions 11-15, provided on a pivotally mounted plate 16, each consisting of support means 17 to receive a stator 18 retained on a clamping fork 19, each support means including an electrical terminal box 20 for clamping the connecting wires 21 of the stator winding.
