Abstract: 427,786. Weft - feeler arrangements for looms. CROMPTON & KNOWLES LOOM WORKS, Worcester, Massachusetts, U.S.A. Nov. 12, 1934, No. 32559. Convention date, May 24. [Class 142 (iii)] A side-slip feeler 50 is carried by a wire 41 pivoted at 48 to a carrier 40 that is pivoted at 32 m a casing provided with a lid. An arm 33 on the carrier is adapted to engage electric contacts 34, 35, while a spring 65 between the detector wire 41 and the carrier normally holds the parts in the position shown with the wire resting against a fixed stop 60. On non-detecting beats of the lay, the detector and carrier are moved into the position shown in dotted lines, the arm 33 being moved away from the contact 34. When the feeler slips due to weft exhaustion, the carrier 40 and wire 41 are turned to the right so that the arm 33 closes the contacts. As the lay recedes, the spring 65 returns the parts to normal position. The carrier carries also a guide arm 87 for the wire, while the casing is adjustable about a centre screw 24 to vary the sensitivity of the device.

Title: Improvements in or relating to the manufacture of quaternary ammonium salts
IPC: C07D295/037
Filed: 1934-11-19
Abstract: Saturated heterocyclic bases such as piperidine are reacted with alkyl chlorides containing at least eight carbon atoms, and the N-alkyl derivatives so obtained are converted into quaternary ammonium salts by reaction with an alkylating agent which introduces an alkyl radicle of not more than six carbon atoms.  In an example, piperidine is heated with cetyl chloride and the product is treated with dimethyl sulphate; the cetylmethylpiperidinium methyl sulphate so obtained is useful in making aqueous emulsions of paraffin, cetyl alcohol, olive oil and like materials, and the emulsions may then be used, as such or after addition of sodium carbonate, for the treatment of fibrous materials.  The emulsions are stated to be more easily absorbed by the fibrous materials than emulsions prepared with the aid of quaternary ammonium salts derived from cyclic tertiary bases of the pyridine type.  The Specification also refers by way of comparison to processes in which salts or quaternary salts of higher aliphatic amines are used as soap-substitutes in impregnating, greasing and revivifying processes and in stripping dyes.ALSO:Saturated heterocyclic bases such as piperidine are reacted with alkyl chlorides containing at least eight carbon atoms, and the N-alkyl derivatives so obtained are converted into quaternary ammonium salts by reaction with an alkylating agent which introduces an alkyl radicle of not more than six carbon atoms.

Abstract: 1,260,889. Pulse circuits; triggering thyristors. BURROUGHS CORP. 3 July, 1969 [5 July; 1968], No. 33580/69. Heading H3T. [Also in Division H2] A system for energizing an actuator coil, for example in a line printer, comprises a capacitor connected in series with the coil and arranged to provide a voltage supplementary to a supply voltage which is applied to the coil. In the arrangement shown in Fig. 1, the coil 12 is connected in series with an oscillator circuit 14 across a D.C. source 11. The oscillator circuit includes a capacitor 24, diode 20 and inductor 22, and is controlled by an SCR 16 having a trigger circuit 18 including a transistor 32. In operation, a pulse is applied to the base of transistor 32 which, together with a diode 34, provides a discharge path for a capacitor 26. A negative pulse is thus applied to the anode of diode 20 causing SCR 16 to be triggered. Oscillation now begins in the circuit 14 as the capacitor 24 discharges through the inductor 22. Now the capacitor reverse charges while the SCR turns off, and the reverse charge on the capacitor supplements the source voltage 11 to provide a high operating current through the coil 12 until a forward charge again builds up on the capacitor 24. The system has now returned to its original state ready for subsequent operation. Capacitor 26 forms a timing circuit with resistors 28 and 30 so as to ensure a minimum time interval between operating pulses.
