Title: Improvements in or relating to the burning of liquid fuel
IPC: F23Q21/00
Filed: 1927-07-04
Abstract: 298,146. Wetherilt, J. N., and Williams, T. G. July 4, 1927. Lighting burners by electrical devices.-In a liquid fuel burning apparatus in which a switch is operated to break the circuit to the electric motor supplying fuel or air or fuel and air to the burner if ignition is not effected or fails, by a piston, bellows, diaphragm or like device to which the pressure of the fuel or air is communicated under the control of a valve operated by the heat or light from the burner flame, some of the fuel is returned through a pipe 19 to the main fuel tank above a bucket 66 provided with a small leak hole 66<a>. The bucket 66 is suspended from a counterbalanced lever 67 carrying two mercury switches 69, 70. When the bucket is empty the mercury switch 69 is closed and, if the motor circuit is completed, sparking occurs at electrodes for igniting the fuel. When the bucket is filled the lever 67 tips thereby opening the switch 69 and closing the switch 70 to complete the circuit to an electromagnet which raises the electrodes above the burner. When the motor stops the leakage through the hole 66<a> empties the bucket and allows the lever 67 to rise, thereby restoring the electrodes to the ignition position. Where a direct current supply is provided the electrodes are arranged in the secondary circuit of a transformer, the primary of which is connected to slip rings on the motor armature shaft. The Provisional Specification describes a form of the burner apparatus in which the ignition circuit and a valve between the suction and delivery side of the pumps are closed when the burner motor is started by the movement of a ball governor driven by the motor.
Patent GB-603224-A (GB)
Title: Improvements in or relating to a method and apparatus for winding yarn
IPC: B65H59/30
Filed: 1944-09-15
Abstract: 603,224. Winding yarns. EVANS, W. E. (Foster Machine Co.). Sept. 15, 1944, No. 17685. [Class 120(ii)] [Also in Group XXXVII] A yarn package is wound at a speed controlled in accordance with the tension of the running yarn, the running yarn initially being subjected to a predetermined amount of friction which is automatically reduced as the diameter of the package increases. In a winding machine having a spindle 10, Fig. 1, on which conical or parallel yarn packages may be wound, the spindle being driven by an electric motor 18, the yarn is passed through a friction gate 22, over a fluted bar 163 and under a drop wire 162 to a guide bar 117, traversing guide 118 and the yarn package. The drop wire 162 is mounted on a lever 160 pivoted at 161 and when allowed to fall due to yarn breakage or slackness it operates a quickacting switch 132 to cut off current to the motor and when raised by the yarn due to increase in tension it operates a switch 133 which, through a relay 134 (see Group XXXVII), cuts off the motor current until the tension is reduced. Each switch 132, 133 includes an operating lever 139 bearing against a plunger 136. The lever 139 of switch 133 has pressed against it a control spring 181 which applies to the lever 139 a pressure which is reduced as the size of the yarn package being wound increases. The guide bar 117 and traversing guide 118 are mounted on a swinging frame 119, adjustably counterweighted so that the frame 119 bears, by a roller 128, against the package. A rod 170, Fig. 7, connected to the counterweight 124 is pivoted to a bar 165 pivoted at 182. A further rod 176 is connected to the bar 165 and to an arm 179 fixed to a shaft 180 to which the control spring 181 is secured, so that movement of the counterweight 124 as the package builds-up causes a reduction in the pressure of the control spring 181 on the lever 139 of the switch 133. Movement of the counterweight 124 also causes, through bar 165 and a rod 172 the friction of the gate 22 to be reduced. A third switch 131, Fig. 1, has a lever 139 arranged to be actuated by an adjustable contact 157 on the swinging frame 119, so that when the package reaches a predetermined size the switch 131 is opened to cut off the motor current supply.

Abstract: 152,760. Parsons, Sir C. A., and Cook, S. S. July 18, 1919. Force-feed lubricating; cooling Lubricant.-In a lubrication system for geared turbines, a single grade of oil is employed, the viscosity of which is varied in different parts by delivering it to these parts at different temperatures. Pumps 4, 5, Fig. 1, deliver oil from a drain tank 1 to coolers 6, 7 from which pipes lead to the bearings and gearing respectively. The cooler 7 lowers the temperature of the oil more than the cooler 6. Each cooler has a by-pass and spring-loaded valve 8, and the two systems are cross-connected by a pipe fitted with a valve 9. In a modification, a single pump is used, the oil dividing after passing the pump; regulating-valves are provided and the cooler 6 is omitted. In another modification, the whole of the oil passes through a main cooler and then divides, the part for the gearing passing through another cooler. A supplementary pump may be provided between these two coolers to force the gearing oil through the second cooler. In another modification, the coolers deliver to gravity tanks, whence the oil is led to the bearings and gearing. The overflow from the tank receiving oil from the cooler passes into the other tank. In another modification, duplicate pumps 17, 18, Fig. 6, deliver oil from the drain tank 1 to a common pipe 19 through strainers 20, 21. Branches 22, 23 lead to coolers 24, 25 supplying oil to the 'bearings and gearing respectively by pipes 26, 27. Duplicate gravity tanks 28, 29 are connected as shown. A non-return valve 31 and a similar but opposite valve are connected in parallel between the pipes 26, 27, By means of these valves and valves 30, oil mav be directed either through the coolers, or through the gravity tanks, or through both, or may be delivered directly to the bearings and gearing. The gravity tanks may have by-passes between the inlets and outlets, with valves. The drain tank 1 may have a partition to separate the drainage from the bearings and gearing.

Title: Improvements in and relating to the treatment of synthetic polypeptides
Inventor: HANBY WILLIAM EDWARD
IPC: D06P3/24
Filed: 1953-07-01
Abstract: The dyeing properties of polypeptides obtained by polymerizing one or more anhydrocarboxyaminoacids at least one of which has an ester-containing hydrophobic side chain are improved by treating them with a base to make some or all of the side cains hydrophillic. Suitable bases are aqueous ammonia, hydrazine hydrate, ethyl-, isopropyl-, or isobutyl-amine, aqueous dimethyl- or diethyl-amine, ethylene diamine, hexamethylene diamine, and sodium carbonate solution.  The ester groups in the side chains are converted into carboxyl or amide groups.  If the treatment is too drastic the polymer may be rendered water soluble, e.g. poly-b -methyl-D.L. aspartate treated with aqueous dimethyl amine or with sodium carbonate may yield a water-soluble product.  Examples describe the treatment for various times and temperatures of copolymers in the form of films or fibres of b -methyl-D.L.-aspartate and DL-leucine with (1) aqueous ammonia, (2) aqueous methylamine, (3) sodium carbonate solution, (4)-(6) hydrazine hydrate, (7)-(12) aqueous hexamethylene diamine, (13), (14) ethylene diamine.  It is stated that the gamma methyl or gamma benzyl ester of anhydrocarboxy-L or DL-glutamic acid may be used in the production of the initial polymers.  Specifications 675,298 and 675,299 are referred to.
