Abstract: 1444010 Preparation of catalyst complexes for olefin polymerization SOLVAY & CIE 24 Aug 1973 [25 Aug 1972] 42465/75 Divided out of 1444009 Addition to 1391068 Heading C3P A solid catalytic complex for use in the (co)- polymerization of olefins is prepared by (a) reducing TiCl 4  with a compound of the formula where R is a C 1 -C 18  hydrocarbon radical, X is halogen and n is greater than 0 but not greater than 3, (b) treating the reduced solid thus obtained with a complexant (c) reacting the treated solid with TiCl 4  to form a catalyst complex which is then separated from the reaction medium and (d) preactivating the catalyst complex less than ten hours after its preparation by contacting it with an organo-metallic compound of a metal of Group Ia, IIa, IIb or IIIb of the Mendeleef Periodic Table. In the (co)-polymerization which may be in the gas phase or in a liquid medium the complex may be used with an organometallic compound of the type used as the preactivator. In the examples TiCl 4  is reduced with AlEt 2 Cl in hexane, the reduced solid is complexed with diisoamylether then reacted with TiCl 4 , and finally preactivated with AlEt 2 Cl, AlEt 3 , or AlEtCl 2  or with AlEt 2 Cl in the presence of propylene, butene or hexene to form a prepolymer and the preactivated complex with or without prepolymer is used with AlEt 2 Cl to polymerize propylene in hexane in the presence of hydrogen.

Title: Production of a tobacco filler rod
IPC: A24C5/34
Filed: 1961-11-29
Abstract: 1,008,776. Automatic control of tobacco. KURT KÍRBER. Nov. 29, 1961 [Dec. 1, 1960], No. 42645/61. Heading G3R. [Also in Division A2] In a machine for producing a wrapped tobacco rod employing a trimming knife 10 to remove excess from a main tobacco stream and a grooved suction wheel 6 to transport it, both the trimming level and the amount of suction are varied in response to the output of an unspecified measuring device 19 situated after, or alternatively, before the trimmer. If before, it is used to measure the main stream e.g. at 44, and the control is not retroactive As shown, the measurement is used to control the position of a shaft 27 attached to which is a cam 30 for adjusting the trimmer 10, and a pulley for a cord 65 by which a valve 53 in the suction pipe is regulated. Also attached to the shaft are two cams which operate upper and lower limit switches,actuation of which causes a stepped adjustment (e.g. 10%) of a variable speed gear 40 controlling the output from a tobacco distributer 1. Alternatively, operation of either switch may cause the distributer output to be adjusted by an amount dependant upon the time that the switch is closed. The shaft 27 is driven through a slipping clutch and its movement is ultimately limited by stops or further limit switches which shut down the machine. It is stated that, alternatively, the measuring device may primarily control either the trimmer or the suction, the second method of correction being brought into use only when the first has reached either limit of its optimum range. The second method may then be operated to return the first to the opposite end of that range. Excess tobacco is returned at a point 45 to the main stream on belt 2 by a wheel 8, while the corrected stream is removed by a stripper 11 and a steel belt 16 and wrapped to form a cigarette rod which is cut to length at 18. Specification 985,988 is referred to.

A fruit machine comprises independently rotatable drums 5a-5c bearing symbols 4a- 4c and perforations 8a-8c beneath each symbol, the perforations being arranged transversely according to the type of symbol associated therewith, and set of feelers 20a-20c positioned adjacent each drum to sense the perforations and actuate a pay-out or indicating mechanism when a winning combination of symbols occurs. The drums are set in motion simultaneously on energization of solenoids 19a-19c and arrested one after the other as the solenoids are de-energized. Each solenoid drives a drum through a pair of pawls cooperating with a ratchet wheel fast with the drum. A solenoid 26 is energized after the drums have been arrested to lower a cross-bar 25 and allow feelers 20a-20c to contact the drums. The pay-out mechanism comprises a solenoidoperated coin slide. In a modification, the sets of feelers control a counter operating the coin slide a number of times corresponding to the winning combination. Alternatively, the payout mechanism comprises a rotatable disc feeding coins from a hopper to a counter. Push-buttons (33a)-(33c) are provided to operate relays (R3a)-(R3c) isolating solenoids (19a)-(19c) and prevent rotation of one or two drums, if required, Fig. 5 (not shown). Each relay (R3a)-(R3c) operates a corresponding relay (R4) to prevent the same pushbutton being used at the next play. Following a winning play, the pay-out solenoid (46) closes a switch (48) to render the push-buttons inoperative at the next play.
