Abstract: 904,634. Feeding sweets. HANSELLAWERKE, A. HENKEL A.G. Oct. 26, 1959 [Aug. 19, 1959], No. 36161/59. Class 78 (1). [Also in Group XVII] A device for feeding articles, e.g. sweets, to a wrapping-machine comprises a continuouslyrotatable plate 1 having pockets 2 on its rim to receive the articles and which slopes upwardly from the pockets towards its axis of rotation and a stationary deflector 8 extending over the path of travel of the pockets. A number of deflectors 8, preferably made of rubber, are mounted on a stationary ring 7. The articles are fed from a container 3 over a vibrator shoot 4 controlled by a switch 5 responsive to the level of a feeler drum 6. The final deflector 8a before the delivery point 17 is extended by a sheetmetal strip 11 to convey surplus articles beyond this point. A foam rubber wedge 12 is also provided for this purpose. The articles slide on an adjustable guide-ring 13 which holds them in the pockets 2 and drops at the point 10 so that pushers on a conveyer chain can remove the articles singly from the pockets 2 to deliver them to the machine. If an article jams between a filled pocket 2 and a deflector 8 the latter gives way upwardly owing to the resiliency thereof.

Filed: 1970-07-27
Abstract: 1323437 Electronic organs R BOHM 27 July 1970 [30 Sept 1969] 36320/70 Heading G5J An electronic organ has a plurality of keys each of which, when operated, effects the production of a predetermined sequence of notes and chords. An embodiment of the organ comprises a sound generator 10, capable of producing signals for certain musical notes, which may be selectively operated by keys, such as 11 and 12. On depression of key 11, signals associated with the notes c<SP>2</SP>, a<SP>2</SP> and f<SP>2</SP> are fed, via resistors 14, 15 and 16, contact 13, collecting lead 17, a control stage 18 and a resistor 19 to a sound forming means 20. At the same time, signals for c, a, and fare transmitted similarly to sound housing 20. Signals for C and F also follow similar channels, and produce a sub-harmonic, by means of voltage divider 40, having the divider ratio 1 : 2. A rhythm provider 46 feeds control pulses to the control stages 18, 27, 32 and 38 to produce a required rhythm. Contact 47 directly connects a note associated with the key 11 to the sound forming means 20 so that when key 11 is depressed a corresponding continuous note is produced. The keys, such as 11 and 12, may be in the form of a manual on the left hand side of a keyboard, and switching means may be also displayed on the keyboard, which are connected to the rhythm provider, to select the required rhythm. An electronic percussion instrument (not shown) may be incorporated, which is controlled by the rhythm provider 46.

The outer conductor 6 may be extruded aluminium or copper and to increase the flexibility a corrugated tube may be used, also a holding layer of plastic tape may be welded around the insulator before the outer conductor is applied, Fig. 4, (not shown). To increase the mechanical stability of the insulator either more than one such laminated spiral is wound round the inner conductor, Fig. 3, (not shown), or the outermost plastic band is made broader than the other bands, Fig. 5, (not shown), or the bands are made broader towards the inside layer, Fig. 6, (not shown).

Title: Difluoramino compounds from ª-diketones
Inventor: GRIGOR JAMES
IPC: C07D319/12
Filed: 1962-09-28
Abstract: A difluoroamino polymeric binder is formed by the polymerization of a 1,2-dialkyl derivative of 1,2-bis-(difluoramino) epoxyethane (see Division C2).ALSO:A propellant composition contains ammonium perchlorate, aluminium, and a difluoramino compound (see Division C2) made by reacting a compound of the formula RCO-COR1, where R and R1 are hydrogen or alkyl, with difluoramine in the presence of chlorosulphonic acid or fluorosulphonic acid.ALSO:A difluoramino compound is made by refluxing a compound of the formula RCO-COR1, where R and R1 are hydrogen or alkyl, with difluoramine in the presence of chlorosulphonic acid or fluorosulphonic acid.  If either R or R1 is hydrogen, two molecules condense to give a tetrakis (difluoramino) derivative of p-dioxane, while if R and R1 are both alkyl, a 1,2-dialkyl derivative of 1,2-bis-(difluoramino) epoxyethane is formed.  In Examples (1 to 4), di-difluoramine is added slowly to a solution or suspension of monoglyoxal or glyoxal monohydrate in methylene chloride, followed by the slow addition of chlorosulphonic or fluorosulphonic acid; after refluxing, the mixture is poured on to ice-water and extracted with methylene chloride to yield 2,3,5,6-tetrakis (difluoramino) p-dioxane; (5 and 6) diacetyl reacted in a similar manner yields 1,2-dimethyl - 1,2 - bis - (difluoramino) epoxyethane; (7) similar treatment of methyl glyoxal produces dimethyl - 2,3,5,6 - tetrakis - (difluoramino) p-dioxane.  The compounds are useful as plasticizers for nitrocellulose, for example in propellent compositions containing also ammonium perchlorate and aluminium.  The epoxide derivatives may be used as monomers for the synthesis of NF2 polymeric binders.

Title: Improved process of preparing cellulose solutions, and process of producing artificial threads, films, bands and such like artificial products from these solutions
IPC: C08B1/00
Filed: 1932-12-31
Abstract: Solutions of cellulose suitable for use in the production of artificial silk threads, films, bands, and similar products, are obtained by dissolving cellulose in sulphuric acid of above 60 per cent strength and then diluting the solution with water, alcohols, acetone, dilute salt solutions or other substance or mixture of substances which are soluble in the acid until the concentration of the sulphuric acid is less than 60 per cent of the solvent medium. The solution which is then in a metastable condition coagulates on standing after a lapse of time which is shorter the lower the concentration of acid and which is also shortened by increase of the cellulose content, or by rise of temperature. When making filaments or films, the concentration of the solution and the temperature are adjusted so that the solution may be subjected to the de-aerating, filtering, and ripening processes without coagulating.  Preferably, the concentration of sulphuric acid in the spinning solution, apart from the cellulose, is between 50 and 60 per cent.  The solution is spun into water, alcohol, or aqueous alcohol and the coagulating liquid may contain dissolved acids, alkalis, or salts.  The process may be carried out at lowered temperature, and under reduced pressure.

The catalyst such as potassium or ammonium persulphate, sodium percarbonate or perborate, and anthraquinone compound may be added stepwise during the polymerization which can be effected at 0 DEG  C., but is usually carried out with heating, external cooling and agitation. Diethanolamine may be added to the latex.

Abstract: 884,466. Optical slide projectors. KODAK Ltd.. Nov. 3, 1959 [Nov. 3, 1958], No. 37224/59. Class 97(1). An optical slide projector includes a shutter which is movable between one position in which it intercepts the projection beam and another position in which it is removed from the beam and a latch which holds the shutter in the intercepting position and is released automatically when a slide is introduced into the projection beam whereupon the shutter is permitted to move to its inoperative position. The slide projector shown has a track 3 for guiding a slide magazine, the slides from which are in turn lifted by grippers 8 into a member 5 having a projection aperture 6. The grippers 8 are secured to a frame support 9 which is linked at 15 to a rod 13 pivoted at 14 and having a lug 16 which rides in a groove 17 of a cam 36, rotatable through gears 18, 19 by a crank 22, 23. A shutter flap 27 is disposed in front of the projection aperture, this flap having depending arms 25 which are pivoted at 26, and have attached thereto a pin 31 adapted to engage the surface of the cam 36. In operation, the cam 36 is rotated so as to raise a slide by means of the grippers 8 into the projection position, such slide being inserted between the wall 42 containing the projection aperture 6 and a pressure pad 37 which has a limited movement in the direction of the projector axis. The movement of the pressure pad caused by the introduction of a slide results in the disengagement of a hook 41 on the pad from a lip 29 on the shutter flap, so that springs 32 move the shutter to open position. Further rotation of the cam causes ejection of the slide and through the engagement of the cam surface with the pin 31 brings the shutter back to its closed position where the lip 29 engages with the hook 41 a pressure pad.
