Abstract: 137,865. Bosch Akt.-Ges., R., (Assignees of Bosch, R. [P'ir7ra of]). March 27, 1916, [Convention date]. I n t e r r u p - ters, mechanical. - Starting or mouth sized running of an internal - combustion engine is prevented, when the cover of the interrupter casing has been removed either by breaking the interrupter circuit or by short-circuiting the interrupter contacts on removal of the cover. As shown, the circuit to the relatively fixed contact d of the interrupted is made from the magneto primary a through the spindle o a plate n on the cover, and thence to the mount for the contact. With removal of the cover the circuit is broken. In other arrangements, the cover carries a projection, which normally holds a contact away from a disk &c. on the spindle o; when the cover is removed, the contact bears on the disk &c. and short circuits the interrupter. An earthing-contact i is provided for the interrupter. The invention is stated to be applicable to distributors.

Filed: 1940-01-25
Abstract: 538,202. Coke ovens. JACKSON, L. MELLERSH- (Koppers Co.). Jan. 25, 1940, No. 1501. [Class 51 (ii)] In a coke oven having one or more coking chambers with vertical heating flues supplied with regeneratively pre-heated air and non- regeneratively heated fuel gas, the air is introduced at a higher level than the gas through interchangeable nozzles, while the gas is introduced at or substantially at the level of the flue base. In cases where the flues are supplied with regeneratively heated air and either non- regeneratively heated rich or regeneratively heated lean gas, the air or air and lean gas mixture are supplied through nozzles at any desired level according to the length of the nozzles. Fig. 1 shows a Becker type oven in which regeneratively heated air is supplied to the flues 12 by nozzles 22, one of which is shown in Fig. 6 with means for effecting its removal. Rich gas is supplied through nozzles 23 at the base of the flues. The size of the ducts in the nozzles 22 is graduated from the pusher to the coke side of the battery. Fig., 7 shows an oven of the kind described in Specification 448,282 heated by rich gas supplied through nozzles 23 and regeneratively heated air through nozzles 22 or by a mixture of regeneratively heated air and lean gas supplied through ports 16, 31 into a common port 32 provided with interchangeable nozzles 22.

Abstract: 540,673. Triazine aldehyde resins ; wetting agents. AMERICAN CYANAMID CO. Feb. 11, 1941, No. 1864. Convention date, Feb. 6, 1940. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] Paper, e.g. for filtering, towels, toilet use, wrapping damp goods or for lamination, is given wet strength by treating it with a solution, preferably in water, containing an aminotriazine-aldehyde condensation product, e.g. melamine-formaldehyde, or resins produced by condensing formaldehyde or its polymers, acetaldehyde, propionaldehyde, butyraldehyde, hexaldehyde, heptaldehyde, crotonaldehyde, allylaldehyde, benzaldehyde, cinnamylaldehyde and furfural with one or more aminotriazines containing one or two amino groups, e.g. melamine and its derivatives ammeline, ammelide, or nuclear substituted aminotrazines or condensed triazines such as melam or melem. Other amino materials, e.g. urea, thiourea and dicyandiamide may be mixed with the triazines, other substances, e.g. phenol, aniline, phenylenediamine, and quinoline may be re-acted with an aldehyde and used with the aminotriazine, and other resins, e.g. urea-, dicyandiamide-, thiourea-, mixed urea thiourea-, or phenol-formaldehyde resins, or alkyd resins, may be incorporated therewith, either made separately or all the material may be re-acted simultaneously. Other materials may be mixed or emulsified with the aminotriazine-aldehyde condensation products, e.g. casein, rosin, albumen, or gum tragacanth. To facilitate impregnation of the paper, wetting agents, e.g. sodium lauryl sulphate, or sulphonate, sodium or other soluble salt of an ester, e.g. the dioctyl ester of sulphosuccinic acid, the sodium salt of alkylatednaphthalenesulphonic acids, soaps, or ethanol, and acetone may be used.

IPC: H04M11/00
Filed: 1953-01-22
Abstract: 784,077. Clocks. TELEPHONE MANUFACTURING CO., Ltd. March 1, 1954 [Jan. 22, 1953], No. 1878/53. Class 139 Ih a clock, signals of five milliseconds duration derived from a radio receiver or from a land line connection are fed over leads 12. Fig. 1, into a respondent unit 13 which closes, for a period of eighty milliseconds, a switch 14 in the operating circuit of a known type of synchronizing mechanism 15. In series with the switch 14 are two switches CA, CB controlled by the clock in such a way that energization of the synchronizing means occurs at halfminute intervals during the middle five minute period each quarter hour. The synchronizing means operate to bring a rocking lever to bear upon the pendulum or balance in such a manner as to accelerate or retard it. A lock switch CC operated by the rocking lever maintains the synchronizing action for the required period. The synchronizing impulses may operate a clock winding mechanism. The responder unit 13 comprises input leads 12. Fig. 2, an amplifier tube V1 and a flipflop consisting of tubes V2, V3. The arrangement is such that on receipt of a timing impulse of five milliseconds duration, the signal is amplified, the tube V3 is rendered conducting and the tube V2 non-conducting. A relay HS which operates the switch 14, Fig. 1, is'operated and capacitor C3 is charged to lock the tube V2 during the period of discharge through the circuit R9, HS and R16 of approximately eight miliseconds. A neon lamp 16 provides a visual indication of the response of the unit to the incoming signals. In another example the TIM signal over lines 20, Fig. 3, enter a responder unit 21 which effects closure of a switch 22 in the synchronizing circuit and amplifies the signal to operate the loudspeaker 23. A switch CA is operated by the clock so that the clock is synchronized at halfminute intervals. The complete signal is amplified and appears across the output 24. The two switches CB, CD are operated by the clock so that a vocal announcement of the time is made at intervals of fifteen minutes. The responder unit is shown in Fig. 4. In the idle condition the tube V1 is conducting and the tube V2 non-conducting. When a time impulse is received on input lines 20 it is amplified by the tube V1 and the tube V2 is rendered conducting to operate the relay HS which, as before operates the synchronizing means. Specifications 362,518, 470,562, 545,910, 566,831 and 623,627 are referred to.

Title: Improved apparatus for heating by steam, more especially applicable to the heating of trains

Filed: 1922-01-26
Abstract: 174,926. Pottier, J. F., and Lannois, L. Feb. 3, 1921, [Convention date]. Fluid-actuated valves.-The admission of steam into each separate heater d<1>, Figs. 1 and 2, of a railway train or like heating system is controlled by a piston-valve l which is normally held open by a spring m, but tends to close under the steam pressure entering from the feed-pipe b, while a further control of the steam admission effected by the temperature of the heater is obtained by means of a valve e and seating k, the valve spindle e<1> being arranged in a casing f and actuated against the pressure of a spring j by means of a thermostatic capsule g located at the end of the steam outlet pipe d<2>. The normal passage n, n<1> for the steam to the heater may, as shown in Figs. 1 and 2, be entirely interrupted, in which case small peripheral grooves f<2> on the piston or similar passages admit a small quantity of steam to the heater, or the normal passage may be only restricted. In a modification, the piston valve, instead of being operated entirely independently of the valve spindle e<1>, is mounted on the latter so as also to be actuated by the capsule g. In a further modification, the piston valve has lateral ports and is arranged to slide over the valve spindle e<1>, a spring being interposed between the piston valve and a shoulder on the valve spindle e<1>. In still further modifications, the valve spindle e<1> is made in two parts with an interposed spring j<1>, Fig. 6, and the lower part e<5> has a square-sectioned rod e<9> passing through a circular passage in the upper part e<7>. When, owing to the expansion of the capsule g, the upper part e<7> engages the seating k, the lower part e<5> and rod e<9> continue their movement, thus placing the feed-pipe b into communication with the atmosphere through the passage in the part e<7> and giving a. more direct blow-off of the condensed water.
