Title: Can packing machine
IPC: B65B25/06
Filed: 1959-04-21
Abstract: 872,497. Packaging-machines. BORDEN CO. April 21, 1959 [April 21, 1958], No. 13529/59. Class 94(1). [Also in Groups XXIV and XXX] A container is filled with articles such as flat cut-outs of biscuit dough, which are fed in longitudinally spaced relation along a path, by presenting the container in turn to feeding stations along the path at each of which it receives an article. Each container is thus filled with articles from different portions of the line of articles, with the result that variations in article thickness due, for example, to unevenness of the dough prior to cutting do not affect the final weight of the package. A sheet of dough 12 is fed by a conveyer 10 beneath a cylindrical cutter 18 which divides it into hexagonal discs 26 and ejects the discs on to support bars, Fig. 3 (not shown), above a series of conveyer belts 28. Projections 32 on the belts engage the articles to feed them towards the filling devices 40. The belts 28 are of progressively increasing length and each terminates adjacent a filling device. Each filling device rotates at belt speed and comprises pockets 48 for cylindrical boxes 44. Above each pocket is a suction head 49 reciprocable by cam and follower means 52, 54, 55, 56, 58, (see Group XXIV). At the first station each head transfers an article to each container, the containers being retained in the pockets 48 by a rail 53. Pressure is raised in the suction head to detach the article from it. A transfer wheel 50 and a guide rail 55a then pass the containers to the pockets of the second filling device and so on until the last belt is reached.

IPC: B23P9/02
Abstract: 135,498. Alexander, A. E., (Lackawanna Steel Co.). Nov. 19, 1919. Milling-machines.-The decarburized surface of partly rolled ingots is removed by milling, the cuttings being carried away by high velocity jets that cool the cuttings and the cutter but do not impinge upon the work. Specification 25212/12 is referred to. The rod is fed by pairs of rolls 2, 3, Fig. 1, through guides and over a supporting roll 6 beneath the cutter 4. In a modification, the roll 6 is replaced by a second cutter. The initial guide has a flared mouth with hardened inserts 42, and an upper member hinged at 43<1> and adjusted at 44. The intermediate guide has a base member hinged at 50, adjustable at 52, and carrying lateral members hinged at 47 and adjustable at 56. The upper member is also hinged to the base and is adjustable at 67. The final guide is similar to the intermediate guide, but extends through the pass of the feed rolls 3. The cutter spindle is mounted similarly to the roll of a rolling mill, and its driving shaft has a belt pulley 115 mounted in separate housing, and similar to the pinion-housing of a rolling mill. All the bearings are simultaneously adjustable by a hand wheel 132. The motor 120 drives the cutter only. Fluid jets are supplied to a hood 25, Fig. 4, shaped to suit the cutter, and are delivered by nozzles 35 flattened as shown. Additional jets 134, 135 cool the cutter. The cuttings are discharged to a hopper by a shoot 33, Fig. 2. The hood carries a hinged baffle-plate trailing on the work and the cutter rotates against the direction of feed. Milling-cutters.-The teeth are formed on an annulus 4 clamped to a body by a detachable ring 26, Fig. 5. Rod and bar feeds.-The feed rolls are arranged, driven, and mounted in housings similarly to the rolls of rolling mills. As shown, the upper rolls are driven from the lower by pairs of pinions 89 and 93. The lower pinions and the roll 6 are connected by the bevel-gearing shown through the spur train 76, 81 from an independent motor 75.

IPC: H01F38/18
Abstract: 135,528. Dessauer, F. April 23, 1918. Transformers.-To lower the stress across the insulation due to potential differences in the windings in a hightension transformer system, condensers or supplementary transformer windings are interposed between the source and the hightension supply windings, the intermediate devices being artificially maintained at a potential between the maximum supply potential and the potential of the source. As shown in Fig. 5, the high-tension secondary winding is divided into three parts A, B, C, the corresponding outer primaries A<1>, C<1> being supplied from 1 to 1 transformers H, H<1>; the part primary C<1> is in series with the part primaries of the transformers H, H<1>. The mid-point of the high-tension secondary is earthed and the intermediate windings are connected to the junctions d, e of the secondary parts to raise their potentials. In another arrangement, where the high-tension secondary is divided into five parts, two sets of intermediate windings are used, the two sets being maintained at graded potentials. Where the high-tension winding consists of two parts in series with the mid-point earthed, the intermediate windings are connected to the middles of the part secondaries; when the high-tension secondary has only one winding with one pole earthed the intermediate windings are connected to the mid-point of the high-tension winding. As shown in Fig. 7, the mid-points of the part secondaries are connected to earth through batteries of condensers F; an adjustable artificial potential is obtained by connecting the intermediate windings between pairs of condensers. Instead of using intermediate transformer windings, condensers, Fig. 8, may be placed between the source and the part primaries A<1>, B', which are connected to the mid points of the part secondaries. Reference has been directed by the Comptroller to Specifications 155,830 and 155,831.

Title: Treatment of certain Plants for Paper Making.
Inventor: STEWART CHARLES JOHN
IPC: D21C5/00
Filed: 1917-09-22
Abstract: 116,005. Stewart, C. J., Hall, H. D., and Beadle, H. Sept. 22, 1917. Materials, fibrous; pulp, preparation of; sizing; parchment paper.-Fibrous material of a soft and yielding nature, such as hedychium coronarium, manila and banana plants, and many other members respectively of the orders Zingiberaceae and Musaceae, are prepa.red for paper-making by treatment with an alkaline liquor at atmospheric pressure and at a temperature which is high but below boiling-point, and to a beating operation. The beating operation may take place simultaneously with the treatment with alkali, or it may follow it or precede it; in the latter case, the material is treated in the stuff-chest. The crops are preferably treated in the green state. For hedychium, the amount of caustic alkali mentioned is 6 per cent of the dry weight of the material treated, and the temperature is 80‹ C. If the material is dry, more alkali and a higher temperature are needed. The materials may be moistened with alkali and baled, the alkali treatment being thus begun during transport. The process may be applied to bales of cotton separated from cotton-seed hulls. Beating may be effected in steamjacketed edge-runners or kneading-machines, followed by refining in the ordinary way. If the alkali treatment is not allowed to proceed too far, the altered matters can be retained in the pulp as a natural sizing-material, a parchment-like greaseproof paper being obtained without the addition of the usual sizing-materials.
Patent GB-729757-A (GB)
Title: Improvements in or relating to the preparation of dichlorohydrin
IPC: C07C29/66
Filed: 1952-05-29
Abstract: Dichlorhydrin is produced by adding allyl chloride and chlorine gradually to an aqueous reaction medium, at least 90 per cent of the water required for the reaction being present in the reaction zone at the start of the reaction.  Preferably the allyl chloride and chlorine are supplied in substantially equimolar proportions. Caustic alkali may be added to the reaction mixture if desired. The process may be effected continuously in at least two successive reaction zones, a portion of the allyl chloride and a portion of the chlorine being continuously added to each zone, at least 90 per cent by weight of the water required being supplied continuously to the first zone and the resulting aqueous reaction medium being passed successively through the subsequent zones. The chlorohydrination reaction thereby takes place in progressively increasing concentrations of dichlorhydrin.  The allyl chloride and chlorine may be added in the gaseous or liquid state and the reaction may be carried out between temperatures of 10 DEG  and 90 DEG  C at atmospheric, reduced or elevated pressures.  In the examples the process is carried out as 1-stage, 2-stage and 3-stage processes.  In the 1-stage process some of the allyl chloride used is converted to trichlorpropane and tetrachlorpropyl ether.

Title: Improvements in or relating to closures for containers
IPC: B65D55/02
Filed: 1952-05-30
Abstract: 707,508. Bottle &c. closures. McINNES, H. L. April 17, 1953 [May 30, 1952], No. 13760/52. Class 125 (3) A tamperproof closure has a screw threaded inner member 4 applied to the bottle or other container and having a lip 6 with an undercut edge 7, and an outer member 10 engaged over the member 4 to prevent access thereto, the lip 6 having resilient lock portions 8 defined by cuts 9 and the member 10 having tenons 11, 12 (not shown) so that downward pressure on the outer cap causes the tenons to ride over portions 8 and engage under the edge 7 to prevent subsequent removal but allowing rotation of the outer cap. The inner member has resilient catches 13 and stops 15 and the outer member has studs 16 aligned on the same circumference as catches 13. Clockwise rotation of the outer member is prevented by the engagement of larger tenons 11 with stops 15 but on anti-clockwise rotation studs 16 will ride over catches 13 until tenons 11 come up against the stops 15 so that once this rotation has been made the outer member cannot move back again but continued anti-clockwise rotation unscrews the closure as a whole. The outer member has a window 17 which after the rotation discloses a message that the container has been opened or tampered with. In a modification (Fig. 8) an inner member 21 has on its horizontal top surface four stops 28 which locate a spring washer 29 having four inclined upstanding resilient catches 30 and on the inside surface of the outer member 26 are two studs 31 which engage the catches and stops, riding over the catches when rotated anti-clockwise but being restrained from relative rotation clockwise by the stops and thus exposing indication of tampering.

Articles having one end hollow fall down shoot 32, and down channels 24, 44, 46 to rest on pin 110. The latter forms part of and is carried by rotor 25 rotatably driven by cylinder 16 about a horizontal axis via rack and pinion 85, 81. Channel 46 is carried by rotor 42 having shaft 54, the ratchet disc 66 of which is positioned by balls 102. Rotor 42 rotates through 180 degrees. Operation.-Suppose that the flat end of the article rests on pin 110. As rotor 25 rotates due to operation of cylinder 16 the article, slips undisplaced, till channel 44 is brought beneath it; whereupon the article falls through said channel and is discharged flat-end-downwards down shoot 36. Suppose that the hollow end of the article rests on pin 110. As rotor 25 rotates, the article grips pin 110 to cause rotor 42 likewise to rotate and when the rotors stop after 180 degrees the article falls flat end downwards into shoot 36 so that all articles are uniformly oriented.

Abstract: 1,105,874. Correspondence control systems. COCHRAN & CO. ANNAN, Ltd. March 31, 1966 [April 1, 1965], No.13884/65. Heading G1N. In a correspondence control system including a control potentiometer RV1 and a feedback potentiometer RV2, transistors VT1, VT2 are connected so that, when the slider of RV1 is moved, the base of VT2 and the emitter of VT1 are positively (or negatively) biased. If the bias is positive VT1 conducts and relay RH is actuated through transistor VT3, while a negative bias causes VT2 and VT4 to conduct sufficiently to actuate relay RL. The motor 1 is thus driven in the appropriate direction to rebalance the system. The sensitivity of the system in either or both directions may be varied by changing the value of R4 or R6, or by changing the forward bias on VT3 or VT4 to change the standing current through the relay coils.

The pull P on a rope uniformly wound on a drum 1 is determined by supporting one end of the drum shaft 24 in a bearing 3 between spring plates 6, 7 and measuring the resulting vertical displacement of this end of the shaft, using an electrical transducer. The bearing 3 is located in a forked block 4 which acts through a member 8 on a hinged arm 9, situated in the space between the legs of block 4, and carrying inside its hollow hub a cylindrical magneto-strictive torsion transducer 12 which is geared to the arm 9 at one end and to the frame 5 at the other. The pull P on the rope deflects the arm 9 and twists the member 12, the torque being measured by the magnetostrictive change in transducer 12. The signal is also dependent on the distance a between the rope and the fixed shaft bearing which is measured by a circular potentiometer 16 driven by the drum shaft, and automatically corrects the signal from the torsion transducer 12. The transducer 12 and its associated parts may be replaced by a load cell (20, Fig. 3 not shown).

Abstract: 1,240,089. Control of D.C. motors. INTERNATIONAL STANDARD ELECTRIC CORP. 24 March, 1970 [1 April, 1969], No. l4221/70. Heading H2J. A D.C. commutator motor M having a permanent magnet field is connected in series with a power transistor T1 which is associated with a control transistor T2 whose emitter is connected to a point between the motor M and resistor R1, and whose base is connected to the tapping- point of a voltage divider R2. This arrangement compensates for variations in the supply voltage, and increases the motor voltage with load to stabilize the speed. To ensure that the transistors T1, T2 are saturated for starting the motor, the voltage across the voltage divider R2 is increased by means of a Zener diode D3 or equivalent which is in series with resistor R5 across the supply. Where the motor has started the armature voltage becomes sufficient to desaturate the transistor T2 through the components D1, D2 and R3. In another arrangement, the voltage applied both to the voltage divider R2 and the motor is increased by means of the diode D3, Fig. 3 (not shown). The voltage divider may include circuit elements for providing temperature compensation.
