Title: Improvements in automatic gramophones or like musical instruments
IPC: G11B3/46
Filed: 1928-07-11
Abstract: 323,819. Automatic Musical Instrument Co., (Assignees of Kenyon, B. C., Boa, W. W., and Green, C. H.). July 15, 1927, [Convention date]. Divided on 293,867. Needles, changing automatically.-Automatic needle supplying and changing mechanism is operated on the return movement of the tone-arm which, when changing is to be effected, first releases the needle gripper for a used needle to fall away and then actuates a plunger, to which a needle has been fed from a magazine, so that the needle is inserted in the needle holder prior to allowing the needle gripper to close. Needles are fed periodically from a magazine 358 by a cylinder 364 having a transverse groove to receive a needle and circumferential grooves engaged by forked fingers 363 which cause the needle to pass into a shoot 365, an abutment 366 therein causing the needle to take an end-on direction in passing down the shoot to a plunger 367. The cylinder 364 is rotated by a shaft 352 and worm gear 350 from the shaft of a clutch-driven drum 91. as described in Specification 293,867, for controlling the operation of an automatic gramophone. A pivoted pawl 370 linked to a spring-controlled arm 374 on a spindle 375 carrying a cam plate 377 normally rests against a disc 356 on the shaft of the cylinder 364 and thereby keeps the cam plate clear of a spring-controlled arm 381 on the needle clamping screw as the sound-box is returned after playing. The disc 356 is however. provided with a notch and, when this is brought opposite to the pawl 370, the spindle 375 can rock so that the cam plate is in the path of the arm 381 which, when the sound-box is next returned, is rocked to permit a spring to eject a used needle and permit insertion of a fresh one by the plunger 367 which is lifted by a rod 368 and link mechanism 385 from a cam 387 on the shaft of the drum 91. The arm 381 then passes clear of the cam plate, so that the spring can rotate the set-screw to clamp the new needle and the cylinder is operated to feed a new needle to the plunger and to carry the disc 356 round so that the pawl is pressed back and the cann plate rocked out of the path of the sound-box. A brush 389 cleans the needle as it passes to the record.

Title: Method and apparatus for producing solid blocks of carbon dioxide ice
IPC: C01B32/55
Filed: 1927-11-15
Abstract: 298,792. Thurston, A. P., (Drgice Corporation of America). March 5, 1928. Solidifying.-Solid carbon dioxide of high density is obtained in large blocks by freezing the liquid under a pressure of from 1500 to 2500 lb. per square inch, the liquid being pumped continuously at approximately freezing temperature into the freezing chamber to make up for contraction. The carbon dioxide is obtained from flue gases by compressing the purified gases in stage compressors 12, 15, 18, freezing- out water, and cooling to the liquefaction temperature in a heat exchanger 21, whence the liquid flows into a separating chamber 26. Nitrogen gas escaping is conveyed by a pipe 29 to a rotary expansion motor 30, where its temperature is lowered to -300‹ F and the gas passes to the freezing plant proper, being used to cool liquid ether by means of coils 45. From these coils the nitrogen passes to the heat exchanger 21, thence to the dehydrator 19, and escapes through pipes 50. The cooled ether circulates about freezing chambers 41 into which liquid carbon dioxide flows from the separating chamber 26, and by opening a valve 61 a small high pressure pump 60 comes into action to raise and maintain the pressure in the freezing chambers to the degree stated. The chambers 41 are slightly coned, so that the ice blocks drop out or are easily ejected when the bottoms are opened.

In an example, 28 parts of semi-pyrophoric iron, 25 parts potassium chlorate, 1 part pyrolusite, 18 parts powdered burnt clay and 1 part gum arabic are mixed with a little water to a thick paste and applied to the article to be ignited.  The gum arabic may be replaced by collodion, acetyl cellulose, glue, starch, &c., and the water in part by organic solvents.

Abstract: 17a  - Hydroxy - 20 - oxo - 21 - acyloxyallopregnane compounds are manufactured by reacting a 21 - halogen - 17a  - hydroxy - 20 - oxoallopregnane compound with an alkali metal salt of a fatty acid containing fewer than 6 carbon atoms in the molecule, in an inert organic solvent for the starting material.  The starting materials may be otherwise unsubstituted or may contain further substituents, e.g. hydroxy, etherified hydroxy, acyloxy or keto groups or corresponding thio groups, especially keto or a -or b -hydroxy groups, or groups convertible thereto, in the 3-position.  Preferably a 21-bromo or 21-iodo compound is heated with sodium or potassium acetate or propionate in an aliphatic ketone in which the two aliphatic groups attached to the carbonyl group each contain fewer than 6 carbon atoms (e.g. acetone). Examples describe the preparation of 3b -acetoxy - 17a  : 21 - dihydroxy - and 3b  : 21 - diacetoxy - 17 - a  - hydroxyallopregnan - 20 - one, and 17a  - hydroxy - 21 - acetoxyallopregnane - 3 : 20 - dione.  Specification 685,331 is referred to.  21 - Bromo - and 21 - iodo - 17a  - hydroxy - 20-oxoallopregnanes are obtainable by brominating the corresponding allopregnane compounds, and, if desired, reacting the resulting 21-bromo-derivative with an alkali metal iodide, e.g. sodium iodide.

Title: Improvements in Automatic Telephone Systems.
Inventor: HULFISH DAVID SHERRILL
IPC: H04Q3/00
Filed: 1918-12-05
Abstract: 136,817. Hulfish, D. S. Dec. 8, 1917, [Convention date]. Drawings to Specification. - Automatic exchange systems.-The system described is the same as that described in Specification 121,471, but the claims relate to the '' change-over " device for altering the circuits at the termination of a series of line impulses. The relay which controls the operation is energized by each impulse, and is kept energized during the intervals between the impulses by currents from the numerical selector controlled by the impulses. The selector takes half a step at each energization and again at each de-energization of its control magnet, and, in positions intermediate between its numerical positions, it closes a circuit through the change-over relay, which therefore remains energized as long as impulses are passing, but relapses when they cease.
