Filed: 1929-02-19
Abstract: 307,063. Universelle Cigarettenmaschinen Fabrik J. C. M³ller & Co. March 2, 1928, [Convention date]. Packeting cigarettes in receptacles. - In assembling horizontal layers of cigarettes &c. with supports or intermediate layers of paper &c., the paper blanks are deposited on a support which is then raised to the level of the bottom of the feed track for the articles, the articles having previously been fed forward with their forward ends overhanging the support, a pusher resting on the bottom of the feed track then feeds forwards both the articles and the blank. The lowermost blank of a pile stored in an inclined holder 33 is fed by a cam-actuated slide 36 against a stop 15 on a feed track and falls on to a table 21 pivoted transversely of the feed track at 22 and supported by a roller 23 running on a cam wheel 24. A pusher 18 thrusts a layer of cigarettes along the bottom 17 of the feed track until their ends overlap the table 21 whereupon the cam wheel 24 raises the table to the level of the bottom 17 and the pusher 18 feeds the cigarettes and the blank into a feed track 29. A lower pusher 31, associated with the pusher 18, feeds forward another layer of cigarettes into a feed track 30 so that when the feed tracks 29, 30 merge into one another, the two layers of cigarettes have a blank between them. The blanks may be cut from a web instead of being drawn from a pile. In a modified form, the pile of blanks is vertical, the inclined table is formed in the feed slide 36 and the blank is fed into place transversely of the direction of movement of the cigarettes.

Abstract: 252,771. Eisler, H., Tibbles, H. J. and Rely-a-Bell Burglar & Fire Alarm Co., Ltd. March 2, 1925. Burglar alarms.-A closed-circuit burglar alarm of the kind giving both an audible and visible signal and wherein the normally closed circuit 1 includes switches adapted to be opened and closed by the bolt of a control lock and by the opening and closing of a door respectively, is provided with one or more vacuum tubes 20 in the secondary circuit of an induction coil 19, the primary of such coil being arranged in the alarm circuit which is controlled by the tongue 13 of a relay coil 6 included in the circuit 1. The tubes, which are of Geissler type, are arranged in parallel when two or more are employed. The closed circuit 1 includes a battery 2, a coil 5 on the alarm bell, a relay coil 6 and switch 7, the latter being controlled bv the bolt 8 of a control lock. When the switch 7 is closed by the bolt 8, as shown in the Figure, the tongue 13 is held out of contact with the contacts 14, 15 and the armature 16 is held out of contact with the member 17. The bell circuit 23 includes a battery 24, and a switch 25, which opens automatically when the control lock is unlocked, and is closed when the bolt 8 is locked. The circuit 23 is also controlled by a circuit 26, bridging the contacts of a switch 25, and includes a switch 27 which is closed by the closing of the final exit door so that the bell alarm is actuated if the control lock is not locked. A lifting magnet 28 for the tongue 13 is operated by a push switch 30 arranged in a circuit 29 having a switch 25 controlled by the bolt 8. A circuit 9 is arranged as a shunt to the closed circuit at a switch 4, the members of which are brought into contact when the final exit door is closed. The circuit 9 includes a switch 10 adapted to be operated by hand to close the circuit when the door is open, and is opened by the engagement of the stem 12 with the door when the latter is closed, such an arrangement enabling the circuit to be kept closed during the exit of the person closing the premises. An electric bell 19<a> of the continuously or intermittently ringing type may be arranged in parallel with the induction coil 19. The relay tongue circuit includes a battery &c. 21 and a switch 22 controlled by the bolt 8. Switches 4 are adapted to be opened by unauthorized persons.

Loud-speakers.-A loud-speaker having a magnetic system comprising four or more poles, at least two of which have single speech coils, and an armature between the poles such that equal currents through the coils produce no movement of the armature, while unequal currents cause the armature to move, is associated with a circuit for each of the speech coils including a direct current source, whereby the direct current flowing through both coils produces like flux changes with no resulting movement of the armature, and. means for producing fluctuating currents cf unequal value in the coils with consequent movement of the armature. The figure shows a pushpull output stage, in which the primary of the usual output transformer is replaced by two coils 39, 40 forming the speech coils of a loud speaker unit, the junction of the coils being connected to the anode battery 24. The permanent magnet 8 of the loud-speaker has pole pieces 31, 32, each with two or more poles 33, 36. Each pole 33 - - 36 may carry a coil, but as shown coils are placed only on the poles 33 and 36. With this arrangement the steady current through coils 39, 40 from the battery 24 produces equal and opposite effects on the armature 37, while speech or other fluctuating currents amplified by the valves produce additive effects, swinging the armature sideways in the gap.
