C.; 146, Boulevard West, Mountain Lakes, New Jersey, and Brisbane, E. E.; Hotel Chatham, 48th Street, New York, both in U.S.A.) -Feb. 15, 1933, No. 4664. Convention date, Feb. 16, 1932. [Class 18.] A box for holding and dispensing pills, coins, ground coffee, sugar, salt &c. adapted in some cases for actuation by one hand only, has a lid 12, Fig. 1, which can only be opened to uncover a portion of the box bottom, a member 16 in the body formed, e.g. by striking up the bottom or by inserting a partition and a flange 19 of the lid forming a barrier which prevents the passage of articles from the covered to the uncovered portion, the uncovered portion being at least in part defined by the barrier. The flange 19 is sprung past an opening 23 to assemble the box and the opening movement of the lid is restricted by detents 21, or by engagement of the flange 19 with the member 16. The flange 19 may have a perpendicular continuation at one end isolating the space in front of member 16 and of such depth that only some of a pile of articles may pass into the dispensing space. In the form shown in Fig. 5, a member 16 covers nearly the whole body and has a flexible tongue 26 pressed down by a detent on the lid so that the space at one corner of the box is isolated. The container may be non-rectangular and the cover may slide along a curve. In Fig. 8 a circular cover 112 carrying a depending flange 115 coacts with a recess in a barrier 116. The cover may be in the form shown in Fig. 4 in which it can snap into position. A finger recess 33 or a projection assists in removing the cover. The container may be incorporated with, e.g. a sugar bowl or coffee can with which it communicates by means of an aperture. The Specification as open to inspection under Sect. 91 comprises also the alternative shown in Fig. 5 (Cancelled), in which an obstructing member 16<1> fixed in the body is arranged in the middle and a rib 30 along the bottom, the flange 19 of the lid preventing movement of contents from the covered to the uncovered part of the box when the lid is open, but not when closed. The member 16<1> may occupy one corner and have but one guiding face 29, or the rib 30 may extend from the member 16<1> to one side wall, the flange 19 at the opposite side being deep enough to push all the articles on that side into the closed part. Instead of using a rib 30 the bottom of the uncovered portion may be sunk. In this form the member 16<1> may be omitted. This subject-matter does not appear in the Specification as accepted.

Feb. 13, 1958 [Feb. 14, 1957], No. 4717/58. Class 111. [Also in Group V] Granules are formed from a concentrated solution or a melt e.g. molten ammonium nitrate by placing the liquid in a vessel 1 and allowing the liquid to fall as drops on to a cool surface whilst vibrating the nozzle in a horizontal plane by an electro-magnetic vibrator 6. It is stated that the horizontal vibration produces multiple trajectories and therefore increases the output of the apparatus and also produces drops of predetermined size. If the drops are to be coated they are allowed to fall into a cooling pad comprising a gaseous suspension of the powdery material with which the granules are to be coated the powder may be calcium carbonate or diatomaceous earth or a mixture of inert materials including the substance to be granulated in a solid state. The bed may be vibrated or current of air or gas may be blown through it. The liquid in the vessel is agitated by a vibrating rod 7. The Specification includes tables giving relations between nozzle diameter height of the column of liquid amplitude of vibration height of fall and the diameter of the drops formed.

Filed: 1973-01-31
Abstract: 1416266 Electronic musical instrument CHICAGO MUSICAL INSTRUMENT CO 31 Jan 1973 [14 July 1972] 4788/73 Heading G5J Automatic rhythm is added to organ output by a rhythm pattern generator which sounds alternately the highest and lowest notes keyed on the lower manual keyboard. Outputs 28, 32, 33, 34; not necessarily in the same pattern, come from rhythm generator 27. Units 29 and 46 modify the tone quality and envelope of the rhythm sound according to outputs 28 and 34. Output 32 drives unit 31 which simulates manual playing in the rhythm pattern while keys are continuously depressed. Output 33 feeds two-phase driver 40 in which transistors (70), (74) (Fig. 2, not shown) conduct alternately, supplying antiphase rhythm potentials to identical current sources 41, 42, one of which will always be supplying a constant 5 ma. to unit 37. A selected number (e.g. 25) of the keyswitches in lower manual 15 supply current to a series of transistors in 37, and in the absence of current to 37 from sources 41 or 42 would cause rhythm tones to sound, supplied by tone sources 25. Bases of the transistors in 37 are connected to stages of parallel opposing chains of diodes, fed at the ends from 41 and 42. Potential drops along the chains ensure that when current is supplied from 41, only the lowest pitch activated note controlled by the transistors will sound its rhythm equivalent, and for 42 only the highest. Bus 44 then adds rhythm tones to the filter and preamp unit 20, where it is modified by the rhythm controls from units 29 and 46, and output from tab switches 17 and 19 is combined. Output from tab switches 18 may be replaced by the automatic accompaniment from unit 31, driven by rhythm output 32.

Title: Improvements in and relating to the manufacture of artificial threads, filaments and the like
IPC: D01D10/04
Filed: 1931-02-16
Abstract: The process of the parent Specification is applied to coils of artificial threads which have been obtained by means other than the box spinning process.  The coils are deformed so that they are no longer annular in shape but so that practically all parts of the threads in the coils are accorded free opportunity to contract on drying without being subjected to undue tension.  The coils may be obtained by winding on to a collapsable core and then removing the wound coils from the core.  A flexible strip of permeable material may be applied to the outside of the core before winding the artificial silk thereon.  The flexible strip is removed with the wound coil and remains inside the coil during the washing and other treatments and also during the deformation and drying.
