Title: An arrangement for withdrawing cigarettes from a feed stock, their alignment, grouping and insertion into sleeves, boxes or the like
Inventor: BASUS JIRI
IPC: B65B19/10
Filed: 1946-07-03
Abstract: 612,079. Cigarette-packing machines. SKODA WORKS, PLZEN. July 3, 1946, No. 19942. Convention date; July 3, 1945. [Class 94 (i)] A machine for packing cigarettes comprises a feed chamber 1 divided into a number of feed columns by partitions 2 which extend through slots 10 in a plate 9 that forms a bottom to the feed chamber. Raised projections 11 formed at the centre of this plate abut against the lowest layer of cigarettes so that as the plate moves to one side this layer is forced under a guard 19. On the return movement this guard prevents the return of these ejected cigarettes and causes them to drop onto a desk 18, whilst the projections 11 force a further layer of cigarettes under the guard 19 on the other side. On further reciprocating the plate, the front edge of this plate pushes the first layer of cigarettes from the desk 18 into a receptacle 7. As the plate reciprocates to and fro this process is repeated on both sides of the feed chamber. Each receptacle 7 is mounted on a vertically movable support carried in a radial arm 6. The radial arms 6 are rotated and the height of the receptacle is varied by altering the height of the guide ring 8 so that one layer can be inserted in the receptacle on top of another layer as the receptacle arrives at opposite sides of the feed chamber.

Abstract: 403,158. Concrete bridges. BAUER, B., 51, Mariahilferstrasse, Vienna. July 14, 1932, No. 19955. [Class 20 (i).] Concrete arches for bridges are cast in situ by the use of a light metal framework insufficient in itself to carry the dead weight of the finished bridge but serving, when strengthened by the first section of concrete cast, as a support on which the remainder of the bridge may be built without the aid of temporary supports. The steel framework is built up of flanged sheetsteel bars a placed edge uppermost and joined grid fashion, the joints being connected longitudinally by connector section-bars l apertured to receive reinforcing bars n, and by diagonals m. The lower longitudinal connectors support the shell or form o which may be of corrugated sheets. In a modification, Fig. 2, the steel framework is of double-grid formation connected by joint bars d, the joints being connected by channel bars g, and the shell k is adjustably supported by nuts ion bolts h. The joints may be connected lengthwise of the bridge by diagonals e instead of by longitudinals, or longitudinals composed of double angle-irons f may be used in conjunction with the diagonals.

Filed: 1948-07-29
Abstract: 652,807. Supply systems for space discharge lamps. DAVIS, B. A., and WRIGHT, W. J. July 29, 1948, No. 20271. [Class 38 (iv)] A system for supplying a plurality of discharge tubes from a low-voltage source particularly for the internal illumination of vehicles includes means for supplying current from the source to the tube heaters, means for creating a voltage surge to strike the tubes and means for opening the heating circuit to each tube in sequence, thereby starting each lamp in sequence. In the arrangement shown, the low voltage supply which may comprise the vehicle battery feeds a rotary transformer RT, the output current of which, to preheat the tubes electrodes, is taken via a polarity change-over switch RS (combined with the input " On/Off " switch), a choke Ch to provide the usual voltage surge, through the filamentary electrodes of the lamps T1, T2, T3, series-connected by contacts 10, 11, 12 of relays R1, R2, R3, and ballast resistances 13, 14. The coils of relays R2 and R3 and the heaters of thermal switches Thl, Th2 and Th3 are energized from the source over contacts of the relays. Switch Th2 closes to short-circuit part of the resistive ballast, and with a timedelay switch Th1 closes to energize relay R1, whereupon contact 10 opens to interrupt the heating current and cause the choke to strike tube T1; contact 10c maintains the relay energized and contact 10a opens to de-energize relay R2 whereupon contact 11 opens to again interrupt the heating current, now passing through the discharge space of tube T1, and start tube T2 ; contacts 11a, 11b interrupt the heating current to switch Th1 and contact 11c de-energizes relay R3, whereupon contact 12 opens to start tube T3; contact 12c interrupts heating current to switch Th2 and thereby remove the short-circuit from portion 13 of the ballast resistance and contacts 12a, 12b interrupt heating current to switch Th3 provided for overload protection whereby the switch Th3 operates to blow fuse X and interrupt the coil circuit of relay R. The ballast resistance may be included in the low-voltage circuit (Fig. 2, not shown), and the relay contacts may be manually operated. In another arrangement (Fig. 3, not shown), the relay coils provide the voltage surges which are introduced into the heating circuit, through resistances by a thermal switch. Two relays are shown controlling three tubes, the second relay being provided with delayed opening contacts for the third tube.

Abstract: 1,136,028. Colour television. RADIO CORPORATION OF AMERICA. 6 May, 1966 [14 May, 1965], No. 20302/66. Heading H4F. The luminance signal channel in a colour television receiver comprises video detector 13, amplifier stages 46, 58 and delay line 52 to equalize the delay in chrominance circuits, the circuit which connects the detector to stage 46 being arranged so that for D.C. and low video frequencies the stage functions as a cathodefollower (thereby providing a suitable driving impedance for the delay line), whilst for high video frequencies the stage functions as a bootstrap circuit to provide increased gain and peaking of the high frequencies. The detector load comprises capacitor 40 and resistor 84 shunted (on the far side of peaking coil 34) by series resistor chain 36, 38, 39. At D.C. or low frequencies the signal across resistors 36 and 38 is applied between control grid 46c and earth to produce cathode follower operation. At high frequencies the signal across resistors 36, 38 and 39 is applied between control grid 46c and the cathode 46b by way of capacitor 82 to produce boot-strap operation. The A.C. output from delay line 52 is applied to control grid 58c of stage 58 via capacitor 64 and the D.C. output is applied via elements 60, 62, 66, 68, 69. Potentiometer 68 provides brightness adjustment. Resistor 76 in the cathode circuit of the stage provides contrast adjustment. The output of detector 13 across resistor 38 is applied to an auxiliary amplifier 86. The high frequency luminance signals together with chrominance signals are-also-applied to the amplifier from the cathode of stage 46 via a capacitor 92. Inductor 90 is resonant with the input capacitance of amplifier 18 at a frequency above chrominance carrier frequency. The amplifier supplies chrominance circuits 19, sync. signal separator 20 and A.G.C. supply 25. In modified arrangements, Fig. 2 (not shown), capacitor 82 is replaced by L-section high pass filter circuits. Transistors may replace the discharge tubes.
