Title: Improvements in reversible tractor ploughs
IPC: A01B3/42
Filed: 1951-08-08
Abstract: 728,587. Agricultural implements. CHAMPION, F. July 1, 1952 [Aug. 8, 1951], No. 18644/41. Class 6 (1). In a power lifted tractor drawn reversible plough mounted on a tractor by means of a cross-shaft 12, rotation of a shaft 2 on which are mounted the plough bodies adjusts the inclination of the plough as a whole to the line of draught on reversal of the plough bodies. As shown applied to a plough as described in Specification 661,000, the shaft 2 is rotated by means of a pinion 13 provided with a pin 14 which engages inside a cam 6 which moves an eye-bolt 5 attached to an arm 4 on which is mounted the shaft 12. The cam 6 is attached by a universal joint 7 to a member 8 mounted on a shaft 9 to which is attached a lever 10 moved by a link 11 by the tractor driver. Movement of link 11 raises or lowers the cam 6 and adjusts the angular movement of the shaft 12. A stop 19 is provided on shaft 2 which abuts alternately against levers 20 or 21 which are adjustable by means of a link 25. By adjusting the position of either of the levers 20, 21 the angular positions of the plough bodies in their working positions is adjusted.

Title: Polymers of epoxy-halo-substituted alkanes
Inventor: FROW ERIC
IPC: C08G18/50
Filed: 1965-05-04
Abstract: Epoxy-halo-substituted alkanes containing a vic-epoxy group at least one carbon atom of which is directly attached to a halogen-bearing carbon atom, are polymerized firstly by contacting said compound with water or an organic dihydroxy compound in the presence of boron trifluoride at a temperature from 60-90 DEG  C. to give an adduct in which the mole ratio of the epoxy-halo-substituted alkane to the water or dihydroxy compound is not less than 2: 1 and not greater than 6: 1, and then reacting said adduct with further epoxy-halo-substituted alkane at a temperature from -30 DEG  to 40 DEG  C. to give a polymer in which the mole ratio of the epoxy-halo-substituted alkane to the water or dihydroxy compound is not less than 4: 1.  The reaction may be carried out in an organic nonhydroxylic solvent, preferably a polyhalosubstituted alkane such as methylene dichloride, ethylene dichloride and chloroform; dioxan may be used.  The preferred epoxy-halo-substituted alkane is epichlorhydrin but others including epibromhydrin, 2 - methylepichlorhydrin, 2-ethylepibromhydrin, 1,4 - dichloro - 2,3 - epoxybutane and 1 - chloro - 2,3 - epoxypentane, may be used.  Water is the preferred initiator but monoethylene glycol, diethylene glycol, triethylene glycol, monopropylene glycol, dipropylene glycol, tripropylene glycol, resorcinol and orcinol are among suitable organic dihydroxy compounds.  Molecular weights of 2000-2500 are obtained by using controlled quantities of the halo-alkane solvent.

Title: Improvements in and relating to temperature regulators for furnaces

Filed: 1937-07-07
Abstract: 503,518. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. July 7, 1937, No. 18931. Void. Convention date, July 8,1936. [Class 38 (iv)] Temperature.-In the control of furnace temperature hunting due to lag in the response of the temperature sensitive element is avoided by connecting in series therewith two thermocouples having different degrees of heat inertia and heated similarly to the furnace itself. Thus a thermo-couple 12 having substantially no heat inertia is heated by an element connected,in shunt to a resistance 14 in series with the furnace circuit, and on application of heat to the furnace as a result of a low, temperature response of the regulator, originating in the thermo-couple 7, an e.m.f. is immediately developed in opposition to that of the couple 7, whereby the regulator effects an earlier cutting- off of the heat supply. A thermo-couple 13, heated by the resistance 14, and having heat inertia, is connected in opposition to the couple 12 so that the effect of the latter is annulled after a time interval. Adjustment is provided by means of a variable shunt 15.
