Abstract: 505,477. Insulation for dynamoelectric machines ; moulding. HOOVER, Ltd. Oct. 5, 1938, No. 28892. Convention date, Oct. 25, 1937. [Class 35] [Also in Croup V] A moulded insulator for applying to armatures before winding comprises a bush adaptedto surround the armature shaft and integral with a core end plate which engages the ends of the slot liners. In the form shown in Fig. 3, the armature has two insulators 2, 3 each consisting of an end plate 5 integral with a bush 4 and slot liners 7 extending half way along the Each insulator is formed from cellulose acetate in the mould shown in Fig. 1, the lower member 9 of which has an inlet 11 for the material and holes 20 to receive the pins 19 of the upper part.

Patent GB-290246-A (GB)
Abstract: 290,246. Burroughs Adding Machine Co., (Assignees of Horton, A. A.). May 11, 1927, [Convention date]. Transfer-mechanism. - The transfer-effecting segments in an adding and subtracting machine are rotatably mounted upon pivoted arms and means are provided to determine whether the segments or the arms shall be free to move at transfer according as the machine is set for subtraction or addition. As applied to the Burrough's machine described in Specifications 265,122, 265.134, 265,136, 265,140, and 265,152, the transfer segments 20 are pivoted at 21 upon arms 22 mounted on a shaft 29 and subjected to the action of springs 24. Also pivoted on the arms 22 are detents 25 the ends 27 of which, when the machine is set for addition, blocks the segments against rotation by the springs so that transfer is effected by clockwise movement of the arms and segments as a whole due to these same springs. When the machine is conditioned for subtraction, a yoke 74 moved by connection with the add-and-subtract lever rocks the detents counterclockwise. The ends 27 thus free the segments and by abutting against a fixed bar 30 they lock the arms against movement so that transfer in the opposite sense may be effected by rotation of the segments. The passage of the transfer tooth rocks a pawl 36 and thereby a trip lever 31 which is then held displaced by a latch 40. The segment 20 or its arm 22 are now disengaged by the hook 33 of the trip lever but movement of these parts is prevented by a restoring bail 50 carried by arms from the shaft 29 and rocked by connection with the totalizer-engagement control lever 382. The bail is held in its obstructive position by a latch 57 but when the totalizer is withdrawn from the actuators and engages with the transfer segments a pin 58 on the lever 382 trips this latch and the bail is then rocked clockwise by a spring 53 to allow any tripped arms or segments to effect transfer. The restoring bail returns any displaced arms or segments when the totalizer moves into engagement in the succeeding opera. tion of the machine. To lock the transfer pawls 36 against movement in total-taking operations a mutilated shaft 80 is rocked from the total and sub-total keys to obstruct the tails 82 of the pawls.

Title: Improvements in thermal interrupters for electric flash light signals
IPC: G08B5/38
Filed: 1950-11-28
Abstract: 685,255. Thermal switches. SCINTEX. Nov. 28, 1950 [Feb. 11, 1950], No. 29040/50. Class 38 (v) A thermal interrupter for controlling flashing- light signals comprises two bimetallic strips 4, 5 which engage each other at their free ends 7, 6 and under the action of heat are deformable in convergent directions as indicated by the arrows F, F<SP>1</SP>. A contact 8 on the strip 4 co-operates with an adjustable fixed contact 3. The strip 4 is heated by a heating element 10 in shunt with the controlled circuit and the strip 5 by an element 9 in series in the controlled circuit, e.g. a lamp 13. In operation, assuming that the contacts 3, 8 are initially closed, a circuit is completed through the contacts and strip 4 to light the lamp 13, the heater 10 is energized and the heater 9 is short-circuited by the contacts 3, 8. The consequent deformation of the bimetallic strip 4 moves both strips 4, 5 to open the contacts 3, 8. As the heater 9 is now placed in series with the lamp 13, the lamp goes out and the heater 9 heats the strip 5 which moves both strips back to reclose the contacts, the cycle being repeated. As the strips oppose one another, changes in ambient temperature do not affect the operation of the interrupter and as one or other heater is always in circuit, the interrupter will start to operate even if the contacts 3, 8 are initially open. The adaptation to the selection of either of a pair of lamps is also described, Figs. 2, 3 (not shown).

Title: An improved process for refining liquid hydrocarbons by means of liquid sulphur dioxide
IPC: C10G21/10
Filed: 1931-10-21
Abstract: <PICT:0383723/III/1> In the refining of liquid hydrocarbons by liquid sulphur dioxide, the dioxide from the low pressure evaporators &c. is recovered by (1) absorbing it in a solvent, expelling at higher pressure from the solution by raising the temperature, and liquefying in a condenser; or (2) condensing by cooling by an auxiliary liquid of lower B.P. than sulphur dioxide which liquid is thereby evaporated, absorbing this vapour in a solvent at low pressure, expelling the vapour at higher pressure from the solution by raising the temperature, and condensing at the condenser pressur for re-use. Solvents specified are the extracts obtained by treating kerosene with liquid sulphur dioxide, alcoholic solutions of camphor, glacial acetic acid, sulphuryl chloride, hydrogenated aromatic compounds, ethyl chloride, and dichlorethylene; liquid ammonia is specified as an auxiliary liquid.  In the complete plant shown, cooled oil is passed from a conduit 1 up a mixer 2 receiving liquid dioxide by a pipe 6, the raffinate being pumped to evaporators 9, 10, the extract to evaporators 13, 14.  The dioxide expelled by heating the evaporators 9, 13 passes to a condenser 3 by a pipe 15 under a pressure higher than that in the condenser, is liquefied therein, and passed through a cooler 4 and a pump 5 to the pipe 6 and the mixer 2. The dioxide from the evaporators 10, 14 under reduced pressure, together with dioxide vapours from the cooler 4, flows through a pipe 16, and are condensed on a tube 19 containing liquid ammonia, the liquid dioxide returning through a pipe 18 to the cooler 4 and the mixer 2.  The ammonia vaporized by the heat of condensation passes through an evaporator 20 and a pipe 21 to a tower 22 in which it is absorbed by an aqueous solution of calcium chloride.  The resulting solution is pumped through a heat-exchanger 24 and a steam-heated pipe 25, the expelled ammonia passing through an evaporator 26 to a condenser 27 and thence through a pipe 20 to the tube 19.  The calcium chloride solution is returned from the evaporator 26 through the heat-exchanger 24 and cooler 31 to the absorption tower 22.  When the dioxide is absorbed by a solvent therefor the evaporator &c. 19-21 is omitted, the pipe 16 leading the vapours direct to the tower 22, and the pipe 29 leads direct to the condenser 3.
