Title: Improvements relating to sound collecting and sound radiating devices
IPC: H04R1/08
Filed: 1931-08-29
Abstract: 388,757. Mouthpieces ; horns; resonators. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and SUTTON, G. W., 25, Cranleigh Road, Merton Park, both in London. Aug. 29, 1931, Nos. 24372 and 24373. [Class 40 (iv).] A sound-horn for use in transmitting and reproducing instruments such as telephone transmitters, loud - speakers, or phonographic apparatus, and more particularly for breast-plate telephone transmitters, is combined with a resonator of special construction, to reduce excessive transmission efficiency at certain frequencies. In addition, an acoustic damping device may be provided. The resonator consists of a small enclosed chamber having a closed end, or the equivalent thereof, and having at the other end a restricted aperture in communication with the horn. It is so designed as to have the same or approximately the same fundamental natural frequency as that at which excessive transmission efficiency occurs. The invention is shown as applied to a breast-plate transmitter, comprising a mouthpiece M for directing sound on to a diaphragm d. The resonator is provided by enclosing within a chamber c, formed by widening the narrow end of the horn, a cylindrical block b having an annular recess R therein, a restricted passage p forming a communication between the recess R and a passage h through the block, which passage is a continuation of the horn orifice. The recess R may be divided, by a closure half-way along its length, at a point diametrically opposite to the passage p, so as to form two similar resonating chambers with closed ends, but the physical closure may be omitted, each half of the annular chamber R in this case functioning as if it were a closed tube. Additional air resonators may be provided, to reduce excessive transmission that may occur at other frequencies. An acoustic damping device may be provided as one or more semi stiff membranes m clamped across a recess r so as to cover the end of the passage h that is adjacent to a coaxial orifice t in the front member f of the transmitter, to which the mouthpiece is screwed. The membrane m, may be made of bolting cloth or similar fabric, or cotton wool may be used. The damping device may be located in the horn otherwise than at the narrow end. A membrane of silk or bolting cloth may also cover the aperture p.

Title: Method and apparatus for the treatment of extruded polytetrafluoroethylene
IPC: B29C48/885
Filed: 1956-08-09
Abstract: 836,024. Extruding polytetrafluoroethylene. RAYBESTOS-MANHATTAN Inc. Aug. 9, 1956 [Aug. 18, 1955], No. 24399/56. Class 87(2). Extruded polytetrafluoroethylene tubing 3 is passed downwardly through a vertical tower 1 where inflammable lubricant, e.g. naptha, is removed in a zone 4 by blowing a hot inert gas, e.g. nitrogen, carbon dioxide, superheated steam or flue gases, through an inlet 8 and upwardly through the tower and out at exit 10. To prevent excessive volatilization of the lubricant, the hot gas may be cooled by a coil 14. Air is prevented from entering the tower by providing a water trap 11 at the exit from the tower. Any air entering at the upper end of the tower is withdrawn at the exit 10 and may provide a cooling effect. The material is sintered in zone 5 by radiant heat from a heater 6 surrounded by an insulating jacket 7. After sintering, the hot gas acts to provide a soaking zone 13. In order to limit the growth of crystallinity in the material, it may be partly and suddenly cooled by a water spray 17. In order that the tube may be sufficiently flexible for the bend of the water trap, some of the hot gas may be drawn downwardly by a blower 21 to heat this portion of the material. In a modification, the trap may be replaced by a gasket and the blower 21 used to draw off any air that leaks through the gasket. Alternatively the material can be collected within the bottom of the chamber 19 on a reel and emptied at the end of a run.

Title: Piperidiones and process for the manufacture thereof
Filed: 1952-10-01
Abstract: The invention comprises as new compounds 3,3 - di(lower alkyl) - 2,4 - diketo - 5 - methyl piperidines wherein the said alkyl groups contain from one to six carbon atoms, and their 1-methyl derivatives. The compounds which are stated to be powerful narcotics may be prepared by reacting 3,3-di(lower alkyl)-2,4-diketo-piperidines or their 1-methyl derivatives with a formic acid ester in the presence of an alkali metal to form the corresponding 5-hydroxymethylene-derivatives and reducing the latter, or the corresponding 5-aminomethylene- or 5-alkylaminomethylene or 5-dialkylaminomethylene-derivatives obtained by the action of ammonia or an alkylamine or a dialkylamine thereon.  The reaction may be conducted in an inert solvent, e.g. benzene or toluene, and the reduction may be effected with hydrogen in the presence of Raney nickel.  In examples (1a) the 3,3-diethyl derivative is obtained by adding a solution of methyl formate and 3,3-diethyl - 2,4 - diketo p - piperidine to a suspension of powdered sodium in benzene to form the 5-hydroxymethylene compound which is then hydrogenated in methanol in the presence of Raney nickel at 120 DEG  C. under 100 atmospheres pressure; (1b) the same compound is obtained by heating the hydroxymethylene compound with dibutylamine in a closed vessel at 150 DEG  C. to form the 5-dibutylaminomethylene derivative which is then hydrogenated in alcohol containing a small amount of acetic acid in the presence of Raney nickel at 120 DEG  C. and 100 atmospheres pressure; (2) the 3,3-di(n-propyl) derivative is obtained from the corresponding starting material by a procedure similar to that of (1a) except that toluene is used as solvent; (3) 2,4-diketo-1,3,3,5-tetramethyl piperidine is obtained from 2,4-diketo-1,3,3 trimethyl piperidine by a process as in (2); (4) 3-ethyl-2,4-diketo-3,5-dimethyl piperidine is obtained by a procedure similar to that in (1a) except that ethyl formate is used instead of methyl formate; (5) 2,4-diketo-3,3,5-trimethyl piperidine is obtained by a procedure similar to that used in (2).

Abstract: 259,253. Janzen, O. Oct. 5, 1925, [Convention date]. Retarding-devices.-Relates to clockwork timelag arrangement for electric relays in which the clockwork is brought into action by the automatic removal of a locking pawl d from the teeth of a gear-wheel a when the operating lever b is actuated, thereby causing the locking gear g to be driven. In order to obtain a more precise time-lag action, with less force to produce the release, instead of the locking pawl d acting directly on the teeth of the wheel a it engages the teeth of an intermediate gear-wheel f journaled on the link c. The wheel f carries a pinion h solid with it and the pinion drives the wheel a. An adjustable element e is engaged by the end of the pawl d and determines the releasing point.
