Patent GB-297272-A (GB)
Abstract: 297,272. Schweiz Industrie-Ges. Dec. 20, 1927, [Convention date]. Feeding webs.-In apparatus for cutting up a printed paper strip into sections for wrappers, the sectional length being determined by perforations at intervals along the strip engaged by gauge pins or the like, correct registry of each cut with the perforations is ensured by using gauge pins 12 of substantially smaller diameter than the perforations, drawing back the strip after each cut, by gravity due to a loop s or otherwise on release of a clamp 4, until the forward edges of the perforations engage against the pins, and then advancing the strip by gripper mechanism 15 having a forward stroke greater than the correct sectional length, i.e. the distance between the centre line of the pins 12 and the cutters 14, by an amount equal to the difference between the radii of the pins and the perforations. Normally successive perforations in the strip will be brought by the feed movement into central relation with the pins, but slight variations in length between successive perforations can be adjusted within the limits admitting engagement of the pins within the perforations in any relation.

Abstract: 505,177. Automatic control systems. HARDINGE CO., Inc. Nov. 1 1937, No. 29830. Convention date, Nov. 1.1, 1936. [Class 38 (iv)] Sound output.-The rate of feed to a mechanism is automatically controlled by the sound vibrations produced, these being converted into electrical power variations in a control circuit in which the amplitude of such power may be adjusted to a predetermined noise level. Thus a microphone adjacent to a ball mill, and in series with an adjustable resistance and the primary winding of a transformer, may cause current variation in a secondary circuit containing a rectifier, a relay, and a current indicator, and the resistance may be set so that the relay will respond at a given noise level to effect control of an electric motor operating feeding means. The motor circuit may be controlled through a second relay having a time delay, for example a thermal switch having a heating winding controlled by the first relay. The Figure shows a mill 11 and a motor 116 operating feeding means 113. Three energy sources 140, 141, 142 may be added in sequence in the motor circuit to give three feeding speeds, by the operation of two relays 145, 132, the three operating windings of which are selectively controlled by a damped relay 123 receiving rectified current from an amplifier 121, the input to which is controlled by a microphone 120 and means 122 for adjusting the amplifier output.

Filed: 1958-09-18
Abstract: 892,696. Packing matches in boxes. Sept. 18, 1958 [Sept. 27, 1957], No. 29940/58. Class 94(1). [Also in Group XXX] An apparatus for packing matches into boxes comprises a number of intermediate members 5, Fig. 1, intermittently moved around a closed path 2 so as to successively receive a number of matches from a source 19, whereafter each member 5 engages a tray 38 and transfers the matches thereto, the filled tray being then released from the member 5 so that it can be pushed into a slide 78. As shown the apparatus includes means 28 for pushing the matches flush against the end wall of each member 5, means 43 for pushing empty trays 38 past stop means 41 in synchronism with the members 5, a guide 42 causing each member 5 to engage a tray and transfer its contents thereto, a vibratdevice 47, an ejecting stripper 48 acting through a hole in each member 5 to push each filled tray out of its associated intermediate member 5, and pusher means 67 for inserting each filled tray in a slide 78. During this final motion a feeler 77 descends and enters the slide temporarily to prevent the matches from striking the top of the slide. In a modified form, Fig. 15, the intermediate members 5 do not have a base. A table 80 on which the members 5 slide acts as a base. In a modified form, Fig. 18, the intermediate members 5 are carried by radial arms, each member 5 being filled in turn at a station 25 and then rotated to a position where it engages and withdraws an empty tray 39 past stop means 41. Each tray 39 is drawn through a curved path so that the matches are transferred thereto and, finally, compressed air from a source 90, 91, acts on a bore 87 to discharge the filled tray from the member 5. A pusher 67 forces the tray 38 into a slide 78 with the aid of a feeler 77 as before. Instead of the compressed air means a stripper member 94, Fig. 19 (not shown), may be used to remove each filled tray from each member 5. Several types of intermediate trays 5 are described in detail. One particular tray has a false bottom mounted on a plunger, the remote end of the plunger carrying rollers engaged in a guide channel that ensures the operation of the plunger at the correct instant.

Title: Production of titanium mixed halides
Inventor: VAUGHAN GEORGE
IPC: B01J27/06
Filed: 1959-09-04
Abstract: A mixed halide of tetravalent titanium is prepared by reacting under anhydrous conditions a halide of titanium of valency less than 4 with a halogen of higher atomic weight than that of the halogen in the halide of titanium.  Thus bromine or iodine in the vapour phase may be passed over titanium di- or tri-chloride, or iodine in the vapour phase may be passed over titanium di- or tri-bromide, the halide being maintained at 100 DEG -200 DEG C., and the halogen may be carried in a stream of an inert gas.  Purification may be effected by distilling from copper gauze or aluminium dust. The product may be employed as a catalyst component in the polymerization of olefines (see Group IV(a)).ALSO:Conjugated diolefines are polymerized in the presence of a catalyst consisting of a mixed halide of tetravalent titanium (see Group III) in association with an aluminium alkyl.  The titanium halide may be the dichloride-dibromide, trichloride-bromide, trichloride-iodide, or tribromide-iodide.  The aluminium alkyl may be aluminium tri-isobutyl.  The diolefine may be 1:3-butadiene.  The polymerization may be effected in solutions of benzene or iso-octane at ambient temperatures.  The catalyst favours the production of the cis-configuration.  Monoolefines may also be polymerized employing catalysts containing titanium mixed halides for example at pressures of 1-200 atmospheres to give polyolefines of the high density type. Thus, ethylene and propylene may be polymerized either separately or to form a copolymer.
