Abstract: 909,106. Control of A.C. motors. LINDSAY, A. R. Nov. 26, 1958 [Aug. 29, 1958], No. 38127/58. Class 38 (3). [Also in Group XXXVI] An electric circuit for controlling a reversible, capacitor type A.C. motor 36 for automatically lowering and raising a plunger carrying an electrolytic marking head 63 (see Group XXXVI) operates as follows, contacts 88, 97, 124 being closed and contacts 123 open: insertion of a workpiece closes a switch 87 to energize (a) a timer 91 through circuit 103 . . . 105, and (b) the magnetic clutch 106 of the timer. Simultaneously, the motor 36 is energized through timer-operated switch 112 to lower the head 63, whereupon a switch 58 is closed by the feed assembly to energize a transformer 101 and so supply current to the electrolytic circuit. After a predetermined time, the timer 91 actuates the switch 112 to reverse the motor 36, raise the head 63 and thus open the switch 58. The cycle repeats itself each time a workpiece is inserted, the timer 91 having a spring resetting action. The operation is made fully automatic by closing contacts 123 and opening contacts 97, 124, contacts 108, 130 being adjusted to be opened automatically when the feed assembly is raised, to de-energize the timer, which re-sets itself, thus allowing the switch 112 to revert to its original setting. Switch 87 is thus by-passed, and the timer 91 and motor 36 are energized through contacts 123, the apparatus running continuously. U.S.A. Specification 2,798,849 is referred to.

Title: Manufacture of mixed esters of cellulose or a conversion product of cellulose
IPC: C08B7/00
Filed: 1930-12-29
Abstract: The manufacture of mixed nitric acid fatty acid esters of cellulose or of a conversion product of cellulose as described in the parent Specification, is modified in that the nitric acid instead of being added as such at an intermediate stage of the esterification, is wholly or in part introduced in the form of a nitrate at that stage. The nitrate acts in conjunction with an excess of sulphuric acid present in the esterification mixtures. The nitrate is conveniently added in finely-powdered form, and is distributed by kneading.  By the use of nitrate alone, esters containing up to 0,5 per cent nitrogen are conveniently obtained; if, however, esters containing a higher percentage of nitrogen are desired, say above 1,0 per cent nitrogen, it is advantageous to add a part of the necessary nitric acid in the form of free nitric acid previously to, or together with, or after the introduction of sulphuric acid.  In examples, cotton linters are treated with a mixture of acetic acid and sulphuric acid, to the mixture acetic anhydride is added, and later after the acetylation has proceeded to a sufficient extent powdered sodium nitrate and subsequently after mixing a mixture of sulphuric acid and acetic acid, the mixture being allowed to proceed with rise of temperature; in another example, the final addition consists of acetic acid, nitric acid and a larger proportion of sulphuric acid; the solutions obtained may be spun, or after the addition of aqueous sulphuric acid hydrolysed to give acetone soluble products which yield films of good strength and only slight sensitiveness to water. Other nitrates that may be used are those of potassium, magnesium, and zinc.

Abstract: 395,801. Retractive switches ; snapaction switches ; retarding action of switches. HAMILTON, W., Woodlands, Wadhurst, Sussex. Feb. 23, 1932, No. 5434. [Class 38 (v).] In a short-time switch in which an operating member is moved in one direction to close the switch and then allowed to return slowly under the control of a dash-pot to open the switch after a time interval, the contact member of the switch is adapted to be latched shortly after the beginning of the movement of the operating member and is held latched while a spring bearing on it is strained until at a predetermined moment the latch is released and the contact member actuated by the spring. In the form shown in Fig. 5, a contact member 1 carrying contacts 2 and pivoted at 7 is acted on by a spring 15 connected at its top end to a boss 12 on a cross-head connected to the plunger 10 of the dash-pot 8. A strong spring, not shown, normally holds the plunger in the dotted position. On depressing the plunger by means of its knob 18 into the full-line position, the cross-head and boss 12 descend and the spring 15, which was previously in tension and held the contact arm 1 in the open position against a stop, passes through a neutral position and becomes in a state of compression tending to close the switch. The contact arm 1 is however held against movement by a finger 4 on the cross-head, which has moved against a U-shaped spring 3 carried by the arm 1, until the finger is clear of the spring as shown and the arm 1 snaps into the closed position. When the plunger 10 is released, it rises slowly and a similar action takes place, the finger 4 however passing on the other side of the U- spring 3 and the spring 15 changing from compression to tension. A second switch arm 1 is arranged at the other side of the dash-pot and is operated by the same movement of the plunger, if desired at different times. 'In the modification shown in Fig.- 9, the operating member is a lever 25 connected to the plunger of the dash-pot 20 by suitably shaped cam mechanism 23 so that a constant speed rotation of the arm 25 causes a constant speed movement of the plunger. The lever 25 is connected to the contact arm 30 by a spring 34 which is sometimes in tension and sometimes in compression and the movement of the arm 30 to make or break circuit under the action of the spring 34 is prevented by the engagement of a pin 33 on the lever 25 with an arc-shaped portion 32 of the arm 30 until the arm 25 reaches the end of its stroke. The lever 25 is acted on by a strong spring, not shown, tending to move it to the right.
