Title: An apparatus for the feeding of cigarettes from cigarette producing machines to cigarette packaging machines
IPC: A24C5/35
Filed: 1967-11-15
Abstract: 1,212,377. Endless conveyers for cigarettes; feeding hoppers. A. SERAGNOLI, E. SERAGNOLI and M. C. SERAGNOLI, [trading as G.D. SOC. IN ACCOMANDITA SEMPLICE DI ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 15 Nov., 1967 [16 Nov., 1966], No. 50508/67. Headings B8A and B8S. Cigarettes are delivered to a hopper 1 leading to a packaging machine (not shown) by a pair of endless belts 26 at the output of a cigarette making machine (not shown). The cigarettes are fed by the belts 26 on to belts 24 and they build up on the latter within a hopper 7, the level of the cigarettes being trimmed by the action of endless belts 34 running in the direction of arrow f2. A carriage 46 (Figs. 2 and 6) is vertically movable by the action of threaded members 37 (Figs. 1 and 6) driven by gearing 38 and a shaft 40 coupled to a motor 45. The carriage 46 carries vertically extending members 53 which have a camming action on arms 19, 19, carrying the pulleys of the belts 24. Thus at the upper end of the travel of the carriage 46, the belts 24 are spread apart laterally and the cigarettes in the hopper 7 are allowed to fall on ledge-like members 50, 50 (Fig. 5) carried by shafts 49 pivotally mounted on the carriage 46. During this action, further feed of cigarettes by the belts 26 is intercepted by a member 54 upstanding from the carriage 46. As the latter descends the members 53 are lowered and permit the belts 24 to move back to their normal positions under the action of springs 25, 25 (Fig. 4). The member 54 is also lowered and allows the flow of cigarettes from the belt 26 to be resumed. The carriage 46 carries a photo-electric gate 55-55A (Fig. 6). When this is obstructed by the level of the cigarettes in the hopper 3, a solenoid 51 is activated to rotate sectors 47, 47 (Fig. 5). This deflects the ledges 50, 50 and deposits the cigarettes on to the top of those already in the hopper 3. The travel of the carriage 46 is reversed and when it rises again to deflect the belts 24, the cycle is repeated.

Title: Production of filters for the removal of atomic or molecular particles from a flowing gas
IPC: B01J19/00
Filed: 1977-12-07
Abstract: The method gives a specification of the nature and quality of the filter material to be selected, but it also specifies filter volume and filter geometry and, consequently, the design of the filter. Criteria necessary for the design of the filter are specified as mathematical relationships. The conditions which have to be fulfilled by a filter according to the invention are defined in a mathematically clear and unambiguous manner. This achieves the object of providing a method which makes it possible to produce a filter taking account of those material properties of the filter material which are critical for the interaction of the particles to be retained with the filter material and also of its dimensions and which fulfils the objective imposed on it in an optimum way without it being necessary to carry out expensive series of experiments to adapt the filter to the requirements imposed on it.

Title: Continuous polyamide polymerization process
IPC: C08G69/28
Filed: 1964-12-15
Abstract: A process for preparing a prepolymer from aqueous hexamethylene diamine adipate salt solution is characterized by:-  (a) flowing the salt solution in a plurality of thin annular films for 1 to 10 minutes at 195 DEG  to 240 DEG  C. through an evaporator (E) zone at superatmospheric pressure to remove substantially all the water of solution;  (b) flowing a plurality of thin annular films of the non-aqueous salt from (a) for 1 to 15 minutes at 250 DEG  to 300 DEG C. through a pre-polymer forming (PPF) zone at superatmospheric pressure to produce a prepolymer having a relative viscosity of 3 to 20; and  (c) in a rectification (R) zone communicating with E zone, rectifying and refluxing water and hexamethylene diamine vapours evolved from E zone and intermingled with similar vapours evolved from PPF zone so as to control the hexamethylene diamine vapours in both E and PPF zones. In the drawing salt solution preheated to 100 DEG  to 190 DEG  C. under non-evaporating conditions in pre-heater 12 is fed to tray 16 and flows along the inner sides of tubes 20 through E zone 18 <PICT:1079963/C3/1> and then similarly along tubes 26 in PPF zone 24.  Vapours emitted in zone 24 rise up the centres of tubes 26 and similarly up tubes 20 where they intermingle with vapours evolved therein.  The intermingled vapours then pass to R zone 30 from the top of which vapour removed via line 32 is condensed in condenser 33 from which some liquid is recycled via line 36 and other, mostly water, is removed via line 37.  Prepolymer collected in zone 28 is passed via line 29 to a polymer finishing zone where a fibre-forming polymer is produced. The process is stated to permit control of the COOH/NH2 end group ratio and hence the polymer finishing rate and thus to enable production of a deeply dyeable polymer without excessive spinneret drip and gelation problems.

Abstract: 1,122,239. Electro-physical measurement. W.A. WISEMAN. Nov. 30, 1965 [Dec. 23, 1964], No. 52326/64. Heading G1N. The effluent from a gas chromatography column is mixed with just sufficient oxygen to react with all the organic compounds which are carried in vapour phase from the chromatograph, the electrical current necessary to generate this amount of oxygen electrolytically being the measure of the amount of organic compound that has been combusted. In one embodiment, oxygen is generated by an electrolytic cell 1 and reacted with the incoming gases in a catalytic combustion chamber 2, which includes a heated platinum wire. The products of combustion are supplied to a hydrogen burning, flame ionization detector 5, which provides an output signal dependent upon the quantity of unreacted organic compound present. This signal is amplified at 6 and 7 and applied to the cell 1 to cause sufficient oxygen to be generated to react with the whole of the organic compounds and so reduce the output of the detector 5 towards zero. The current through the cell 1 is measured or recorded. In a second embodiment, Fig. 2 (not shown) the combustion chamber 2 is omitted, combustion taking place in the flame ionization detector which is supplied with a stoichiometric mixture of hydrogen and oxygen, any surplus oxygen present in the final effluent being detected to monitor discrepancies between the oxygen generated by the cell 1 and the changing requirements of the organic material in the effluent stream. A signal proportional to this discrepancy may be deducted from the current used to generate the oxygen.

Abstract: 1510878 Recording and playback; indicators for dictation/transcription units DICTAPHONE CORP 23 Dec 1975 [2 Jan 1975] 52671/75 Heading G5R Recording/reproducing apparatus which permits independent recording (dictation) and reproducing (transcription) includes a differential counter for deriving an indication of the amount of dictated material awaiting transcription from signals representing increments of tape passed through the dictation and transcription sites in the apparatus. The requisite circuit (described below) senses indicia on the magnetic tape T at both the dictation and transcription sites and with other inputs performs the following functions: incrementing the output indication for tape advance at the dictation site during dictation but inhibiting any change arising from tape movement thereat during rewind/replay for review purposes; decrementing the output indication for tape advance at the transcription site, but incrementing it for tape reversal thereat (to compensate for review before transcription); zeroing the output indication when all dictated material has been transcribed; and inhibiting and deferring any change in output indication if a prior change is in the course of being effected. The circuit also provides separate cumulative indications of amounts of dictated and transcribed material. The output can be utilized in a centralized dictation system (see Specification 1,510,880). Circuit details, Fig. 2. Three similar channels are provided: a single one at the dictate site takes output pulses from a phototransistor 158, gates them 162 with an input 154 which is present when the tape is at its point of farthest advance (i.e. not present during a review) and stores them in flip-flop 164. The output from flip-flop 164 triggers monostable 166 if the latter is not inhibited by outputs on either of the other two channels, and an output pulse 13 supplied which, via a driver transistor 170 (i) increments the output indication by energizing a coil 146 of an UP solenoid (146<SP>1</SP>), Fig. 3 (not shown) to drive the wiper (192) of a voltage-dividing potentiometer; (ii) increments the dictation counter; and which also (iii) resets the flip-flop 164 after a delay 168; and (iv) inhibits the other monostables 116, 136 for a time determined by CR circuit 180, 182. Output pulses from phototransistors 104 at the transcription site are diverted to one of two channnels by gates 108 110 depending on the direction of tape motion (input 107): in the forward direction, components 114, 116 generate pulses for driving the DOWN solenoid (126<SP>1</SP>) of the output indicator, and the UP section of the transcription counter; in the reverse direction, components 134, 136 effect the opposite functions. When all dictated material has been transcribed, input 174 activates a pulse generator 184 which drives the DOWN solenoid (126<SP>1</SP>) to move the wiper (192) to its zero position.
