Title: An improved label holding device for incorporation in bottle labelling machines
Inventor: OSWALD HENRY JOSEPH
IPC: B65C9/36
Filed: 1956-03-23
Abstract: 814,975. Labelling machines. BARRYWEHMILLER MACHINERY CO. Ltd. March 25, 1957 [March 23, 1956], No. 9057/56. Class 73 A label holding device in a bottle labelling machine comprises a pivoted, positively operated, cranked arm 5 with a vertical limb having a fixed pad 11 to hold a label against the body of a bottle and a spring urged, pivoted part 13 having a pad 17 to hold a label against the bottle's neck; a stop 20 on the frame of the machine (not shown) restricts the post's movement so that its pad 17 does not contact the bottle before the neck label is applied. The cranked arm 5 has a dependent limb 6 housed in a bearing 7 and carrying cam-contacting rollers 9 all on the underside of a table 4 on which the bottles are traversed. The cam (not shown) serves to turn the arm 5 from a non-operative position A to a position B where the pads contact the labels on the bottles which are applied by stationary picker-plates, such as D. The post 13 is pivoted to the vertical limb of two arms 5 at 12a, is urged by the spring 15 to an inclined position to conform with the bottle neck and is constrained in the reverse inclination by a spring supporting bracket 14 on the housing of the pad 11. A holder 16 carrying the pad 17 can be adjusted for height by sliding it along the post and locating it by spring and ball 21 in one of a series of notches 13a. The stop 20 engages the upper end of the post as it approaches the position B whilst a body label is applied and does not release it until the bottle has advanced further to receive a neck label. The stop 20 is adjustable for position.

Title: Apparatus for measuring stretch or shrinkage in material passing through a processing machine
IPC: G01B21/32
Filed: 1952-04-09
Abstract: 738,748. Measuring continuous lengths; testing fabrics. FIRESTONE TYRE & RUBBER CO., Ltd., and COLLINS, J. B. April 8, 1953 [April 9, 1952], No. 9060/52. Class 42 (2). Apparatus for measuring stretch or shrinkage in material passing through a processing machine comprises two master magslips respectively driven in synchronism with the material at the-input and output end of a processing machine, the master magslips being connected to drive two slave magslips arranged to drive mechanically revolution counters showing respectively the total yardage processed and the difference between input and output yardage (i.e. total stretch or shrinkage). As shown, idler rollers 10, 11 are rotated by contact with fabric at the entrance and discharge ends respectively of a dripping apparatus. Rollers 10, 11 drive, through reduction gearing master magslips 17, 18 connected electrically to slave magslips 19, 20 which can be located remotely from their masters; the electrical connections are such that magslips 19, 20 rotate in synchronism respectively with magslips 17, 18. The rotor shaft 28 of magslip 19 is geared to a counter 45 indicating the input yardage of fabric passing over roller 10. Shaft 28 is also, together with the rotor shaft 31 of magslip 20, geared to a differential mechanism 30, the output shaft 33 of which rotates at a speed proportional to the difference of speed of shafts 28, 31. The rotation of shaft 33 is transmitted through a friction clutch 34, 35 to an indicator 37 showing the total stretch or shrinkage of the fabric passing over rollers 10, 11. By comparing the readings of indicator 37 and counter 45, the percentage stretch for any desired total length can be calculated. In a modification, a first slave magslip is coupled as above to master magslip 17 and drives counter 45; a second slave magslip has a triply-wound rotor and its stator and rotor are connected respectively to the stators 21 of master magslips 17 and 18, so that it acts as an electrical differentiator and drives the stretch indicator 37 direct.

Title: Process for the emulsion polymerisation of styrene and related compounds
IPC: C08F2/16
Filed: 1952-04-09
Abstract: In aqueous emulsion polymerization or copolymerization of monomeric aromatic compounds having ethylenic unsaturation in the side chain a solution of emulsifying agent in the monomer is gradually added to an aqueous medium substantially free from polyvalent cations and a polymerization catalyst is also gradually added, the relative rates of addition being such that the addition of the catalyst is not completed until after the addition of the emulsifying agent. Monomers specified are styrene, a -chloro, a -methyl and a -ethyl styrenes, o-, m- and p-chloro-, methyl- and ethyl-styrenes, a -methyl-p-methyl styrene, dichloro-, dimethyl- and diethyl-styrenes, vinyl naphthalene, and vinyl diphenyl.  Co-polymerizable compounds may be vinyl and vinylidene compounds, e.g. acrylic and methacrylic acids, allyl compounds and maleic acid and its esters.  Suitable emulsifying agents are sodium dodecyl benzene sulphonate (dissolved in hot monomer) sodium dioctyl sulphosuccinate, and the sodium salts of mahogany acids.  Catalysts mentioned are potassium and ammonium persulphates.  Plasticizers, e.g. dibutyl phthalate with oleic acid, butyl benzyl phthalate, stabilizers, buffers, dyes, pigments and protective colloids may be added before or after the polymerization. A reflux temperature is preferred for the polymerization and the process yields stable emulsions with a particle size of 0.15 to 0.35 microns and is particularly suitable for the production of a high solid content (40-60 per cent.) emulsion.

Title: Improvements in regulator control apparatus
IPC: H02J3/50
Filed: 1960-03-15
Abstract: 943,400. Automatic control of alternators. GENERAL ELECTRIC CO. March 15,1960 [April 1, 1959], No. 9099/60. Heading G3R. In an alternating current generating system including a plurality of polyphase synchronous generators a reactive load division circuit is associated with each generator whereby the algebraic sum and difference of the real and reactive loads are determined and compared, the resultant signal being used to modify the action of a regulator controlling the generator excitation. As shown, alternating current generators 34 have field windings 5, 6 energized from exciters 11,12 controlled by automatic regulators 13,14 developing controlling direct voltages proportional to the output voltages of the generators. Each generator has associated with it a reactive load division circuit in which the voltages across secondaries 30, 31 of a transformer 27, having a primary connected between phase B and the neutral N, are combined with the voltages across secondaries 24, 25 of a transformer 22 and rectified by full-wave rectifiers 35, 37 so that the direct voltage developed across a load resistor 41 is dependent on the vectorial difference between the phase voltage and the primary voltages of transformers 22 and the voltage across a load resistor 40 is dependent on the sum of the alternating voltages. The voltage applied to the primary of the transformer 22 is derived from parallel-connected current transformers 20 responsive to the currents in the phases C of the generator outputs. The voltages across the resistors 40, 41 are connected in opposition so that a modifying signal is applied to the regulator 13.

Title: Improvements in or relating to electric current supply installations employing rectifiers to feed a load
Filed: 1957-03-21
Abstract: 860,828. Automatic control systems for rectifier power supplies. SIEMENS-SCHUCKERTWERKE A.G. March 21, 1957 [March 21, 1956], No. 9356/57. Class 38 (4). In a D.C. power supply system only one main rectifier is voltage-regulated by a device provided with a datum voltage source, the other rectifiers being regulated in dependence upon a quantity supplied by this rectifier. Two main rectifiers 1, 2 supply a common load 5 connected to D.C. bus-bars 3, 4. Rectifier 1 is controlled via amplifier 13 by voltage regulator 8, which compares the D.C. output voltage with a stabilized voltage derived from the line voltage of the 3-phase supply. The output voltage level is set by rheostat 29. Load-sharing between the rectifiers is achieved by comparing the I.R. drop across series resistors 18, 19 in their respective load circuits. Any difference causes a circulating current between them in a circuit including the current control windings of amplifiers (e.g. magnetic) 13, 20 whereby the rectifiers' conduction is varied to balance the load. An auxiliary rectifier 6 is connected so that its output voltage, added to the bus-bar voltage, charges a battery 7. The auxiliary rectifier is controlled by voltage regulator 21, which compares the output voltage across lines 26, 27 with the bus-bar voltage across lines 22, 23. Mention is made of connecting the main rectifiers to the load in succession, in dependence upon the load.

Abstract: 541,566. Tubular films. HEAVEN, H. S. May 31, 1940, No. 9586. [Class 2 (ii)] A seamless, flexible tubular body is made from a cellulosic solution, such as viscose, by extrusion from an annular die into a coagulating bath, and the space in the tubular body close to the die is separated from the space remote from the die. The pressure in the former space only slightly exceeds that acting on the exterior while the pressure in the latter space is maintained substantially higher than the exterior pressure. The annular die 25 is supplied with material through the conduit 26, and this material is extruded into the coagulating bath 28. It passes in tubular form, slightly downwards, beneath a glass rod 29 which holds it depressed, after which it emerges from the bath and may be sprayed with treating and washing media. The gaseous pressure in the remote part 39 can be varied by raising or lowering the depression rod 29. The back end of the extrusion die can be left open for the coagulating liquid to enter the near part 40 of the tube or, as shown, the end of the die can be closed by a rubber bung 31 with conduits passing through. The conduit 32 supplies coagulating liquid to the interior of the tube and this liquid is withdrawn through the conduit 33 while the pressure of this liquid is indicated by the level in the conduit 35. The gas pressure in the part 39 of the tube is maintained by the supply of gas through the conduit 34 and the flexible tube 40. Specifications 408,774 and 540,747 are referred to.
