Title: Adhesive-applying mechanism
IPC: B65C9/22
Filed: 1932-11-12
Abstract: <PICT:0399333/III/1> <PICT:0399333/III/2> Apparatus for applying a strip of paste &c. to a label or other sheet comprises an endless band formed of a helical spring which is guided into contact with the label &c. and receives its supply by contact with a pasting roller; the tension of the belt can be varied to vary the amount of paste carried thereby, and means are provided for removing surplus paste from the belt as it leaves the pasting roller.  The apparatus is described as applied to a labelling-machine in which cylindrical objects are rolled over a paste supply and pick up the uppermost label of a pile, the rear end of the label being pasted by the band. Figs. 1 and 2 show sectional views at right-angles, the objects 1 being rolled, by contact with a band 3, along a track 2 past a pasting-roller 5 to a pile 8.  The top label is detached by the pasted object, which rolls along elevated tracks 9 and withdraws the rear end of the label from the pasting band 11.  The latter passes over a grooved driving pulley 19 and makes contact with a pasting roll 28. Excess paste is removed by a pivoted forked member 30 which straddles the pulley, and by a blade 62 which engages the inner side of the belt.  The belt passes over an adjustable guide 22 comprising a number of radially-disposed, grooved members 40, the plane of the guide being inclined to the vertical so that the upper run of the belt lies beneath the solid part 14 of the track 9.  The belt then passes over a stud 23 to a guide 24 formed with a groove which leads the belt into contact with the top label at a point slightly away from the edge, the side walls of the groove depressing the label surface at this point.  The stud 23 and guide 24 are formed in one and are adjustably mounted.  The belt is held in contact with the middle part of the label by an adjustably mounted rod 25.  The belt can be readily removed for cleaning.

Title: Injection moulding control system
IPC: B29C37/00
Filed: 1974-07-23
Abstract: 1483741 Control of injection moulding HUNKAR LABORATORIES Inc 23 July 1974 [19 Oct 1973] 32573/74 Heading G3N An injection moulding machine is of the type having a ram 16 which, when it advances (to the right in Fig. 1) injects plasticized material into a mould cavity 23 and when it retracts rotates to plasticize the material to be injected in the next advance phase. The invention consists in a control system for such a machine, the general organisation of which is broadly the same as in the system shown in Fig. 1 of Patent No 1411112 (which is referred to). The principal differences between the present system and that of the prior patent are the substitution of a single flow-divider valve 43B for two independent flow-control valves (45, 52) and the fact that, in the present case servo-control of the ram is continuous throughout each advanceretract cycle. Another difference between the present and the prior patent is that not only the advance but also the retract are limited by pressuresensitive control elements, the single pressure transducer (72) of the prior case being replaced by two such transducers 48, 101. A control system incorporating this two-pressure-transducer arrangement is claimed in Specification 1483742. Fig. 2 (not shown) is a block diagram illustrating the inter-relation of the control functions performed by the Fig. 1 apparatus in use. Figs. 3 and 4 (not shown) depict sub-systems whereby, during the retraction phase, appropriate variations in back pressure and rate of screw rotation are obtained.

Abstract: 341,973. Autographic registers. LAMSON PARAGON SUPPLY CO., Ltd., 132, Cheapside, London.-(American Sales Book Co., Ltd. ; 6, King Street East, Toronto, Canada. Oct. 26, 1929, No. 32594. [Class 100 (i).] Feeding webs.-In autographic registers or other manifolding machines employing record strips, a detent actuated by the strip-feeding mechanism and co-operating with a lug or shoulder connected to the strip-feeding member to stop it at a predetermined position is provided, and a separate locking device is also provided controlled by the operating member and adapted to prevent accidental feeding of the strip. The device comprises a casing provided with a compartment for a supply of blank strips preferably folded in zig-zag form, a platen over which the strips are fed, and a filing compartment as described in Specification 229,616. The feeding device consists of a pair of discs 15 mounted on a shaft 14 and co-operating with a spring-pressed roller 17 carried in a releasable housing 18 on a casing, the discs 15 and roller 17 being rotated in unison by gear wheels 22, 23. The end of the shaft 14 is formed with a head 24 provided with a spring- pressed pin 25 adapted to engage a slot in a gear wheel 27 rotatable on the head 24. The slot forms a shoulder at one end, and gradually inclines upwardly from that end, so as to form, in conjunction with the pin 25, a one-way driving clutch for the shaft 14. The gear wheel 27 meshes with a toothed sector 33 rotatable on a pin 31 and provided with an operating handle 34. A spring 37 tends to return the handle to initial position after actuation to feed the strips. The sector 33 is provided with a projection adapted to engage with a notch 41 in the head 24 at the end of the feeding movement to limit the movement to that which is sufficient to feed forward one form on the strips. Au the end of the return movement a smooth convex face 42 on the sector 33 engages a concave face on the head 24 to prevent accidental operation. A buffer 38 and a yielding surface may be provided for preventing shock to the mechanism at the end of the return movement. A pawl engaging the gearwheel 23 may be provided for preventing reverse rotation of the mechanism which may be enclosed in a housing 47. Specification 229,616, [Class 16, Books, &c.], is referred to.
Patent GB-1240502-A (GB)
Title: A method of heat exchange between a gas and an article
Inventor: PLUMAT EMILE
IPC: G01T1/115
Filed: 1968-07-09
Abstract: 1,240,502. Treating glass. GLAVERBEL. 9 July, 1968 [12 July, 1967], No. 32643/68. Heading C1M. In a method of effecting heat exchange be - tween a gas and an article (e.g. a glass sheet), a sheet 60 is supported wholly or mainly by a cushion of gas 67 at a temperature such that heat exchange (e.g. in tempering) occurs, the cushion being maintained by discharging jets of gas upwardly against the bottom of the article from a plurality of discharge orifices 64 distributed within the area covered by the sheet 60 and displaced so that while each jet of gas is impinging against the sheet the orifice moves with a horizontal component of motion along a trajectory which approaches and then recedes from the sheet while the jet is simultaneously angularly displaced so that its axis sweeps through an angle bisected by a vertical plane. Preferably the orifices 64 are formed in rollers 61-63. The sheet is caused to move relative to the rollers during the heat exchange treatment; this movement may be effected by the gas jets. The arrangement of the jets may be such as to allow a gas jet to act repetitively on a part of the sheet, and may also cause the path swept by one jet to overlap the path swept by another jet. In a further embodiment (Fig. 4) a sheet or ribbon 82 of glass is preheated in a chamber 85 and passed into a chamber 88 where it is heated to its softening point by gas jets from upper and lower blowing rollers 92 between which it passes. The sheet is tempered in chamber 86 as it passes between opposed pairs of upper and lower blowing rollers 94a, 94b. The movement of the gas jets may be provided by forming the orifice in an endless belt passing over a blowing chest (Fig. 8, not shown). A suitable pattern of orifices for the rollers 61-63 is in the form of helices. The method may be used to bend glass sheets, e.g. for motor vehicle windows. It is also applicable to glass tubing, metal, ceramics or plastics materials. Whilst it is desirable to wholly support the weight of the article by the gas jets contact with the rollers is possible provided that the contact pressure between article and roller is kept to a minimum by equilibrating the article weight by the gas jets. With glass sheets their temperature should not exceed 620‹ C. if such contact is made and the rollers must be coated with a material to which the glass does not stick, e.g. boron nitride.

Title: Improvements in or relating to circuit-arrangements for providing a sawtooth-like current in the deflecting coils of a cathode-ray tube
IPC: H03K4/43
Filed: 1946-11-04
Abstract: 632,175. Saw-tooth circuits. PHILIPS LAMPS, Ltd. Nov. 4, 1946, No. 32710. Convention date, Nov. 7, 1945. Drawings to Specification. [Class 40 (vi)] In the output stage of an electromagnetic time base, the primary of the output transformer is given such a value that the mean anode current is a minimum for a given output at a given frequency. Any distortion of the output current wave caused by giving the primary inductance this value, rather than making it as high as possible, is avoided by partially integrating the driving voltage before applying it to the stage, or by providing negative current feed-back.

IPC: C10J3/24
Filed: 1926-12-24
Abstract: 266,681. Humphreys & Glasgow, Ltd., (Assignees of Parsons, M.). March 1, 1926, [Convention date]. Producers.-Apparatus for making gas, such as carburetted water gas, is provided with automatic mechanism for operating control elements and putting them in shut down position and with electrical means responsive to improper positioning of the apparatus elements and adapted to operate the automatic mechanism to put the control elements in shut down position and interrupt the gas making operation until the apparatus elements are again properly positioned. The apparatus includes a generator 1, carburettor 2, superheater 3, waste heat boiler 4, wash box 5, gas holder 6 and dust catchers 8. Doors 7 provided to various of the vessels, the water feed 9 to the wash box, and the travel of the holder 6, which must not be too full, constitute the elements, the improper positioning of which put into operation the control elements. A control element is the air blast valve 10 which is operated by a hydraulic cylinder 12 controlled by a valve 13 operated through a hand lever 14 which may also be operated by a rock-shaft 16 connected with a hydraulic cylinder 17 the valve 18 of which is pressed into the closed position by a spring 19. The other control elements are moved to the shut-down position by the spring 19 and similar mechanism. In series in the circuit 20 are arranged interrupters at each door 7 and at the contacts 26 and 27 used in connection with the holder and wash water supply respectively. So that if any of the doors be open or the holder filled to its limit or the water supply stopped the current energizing an electromagnet 30 is cut off and the spring 19 operates to put the control elements into the shut-down position for interrupting the gas making. Specifications 229,399 and 238,519 are referred to.

Any glass may be thus reinforced and may be curved, concave, convex or cylindrical. The plastic layer may be decorated, coloured, engraved, carved or rendered matt before or after assembly.  In examples: (1) a plate of glass is sprayed with a solution which leaves an adhesive layer of cellulose acetate, ethyl lactate and ethyl silicate to which is applied a 5 mm. layer of cellulose acetate, triphenyl phosphate, dimethyl phthalate, and triacetin; (2) five sheets each 0,5 mm. thick of similar composition to that in (1) are immersed in a bath of ethyl lactate, triacetin and ethyl silicate and assembled while in the bath on a glass sheet.
Patent GB-307718-A (GB)
Title: Improvements in and connected with thermostatic controls for dynamo electric machines
IPC: G05D23/275
Filed: 1927-12-06
Abstract: 307,718. Stone & Co., Ltd., J., and Darker, A. H. Dec. 6, 1927. Regulation, automatic. - A dynamo-electric machine which supplies the current for a railway vehicle heating system or which operates the compressor of a refrigerator is controlled by means of a heat-sensitive element which completes a lowvoltage circuit of a relay which controls the circuit of an electromagnetic switch which controls the dynamo-electric machine. An axledriven dynamo d, Fig. 1, is connected by positive and negative leads a, b to heaters h and to a fan f for circulating the air. A mercury column thermostat t is connected to the coil r of an electromagnet switch having a potential difference of about 1 volt derived from a potentiometer p across the mains. The switch contact r<2> is connected to the terminal s<1> of the solenoid coil s, the other end of which, s<2>, is connected through a hand switch m to the positive main a. The field winding of the dynamo is connected by a wire e to a terminal o and thence through resistance p<1> and terminal S<SP>2> to the main a. The resistance p<1> is shunted by a coil p<2> wound non- inductively with the coil s, and its effective resistance is varied by making the resistance p<1> an interchangeable unit. The contact member q carried by the armature is connected by wire q<1> to terminal s<2>, and normally rests on contact q<2>, so that the resistances p', p<2> in series with the dynamo field winding are short circuited, and the maximum current supply is available for the field windings. If the thermostat makes contact at t<2>, the relay operates to raise the contact member q, insert the resistance p', p<2> in the field windings, and thereby reduce the dynamo excitation and supply of current to the heaters h. The position of the contact t<2> is adjustable to vary the temperature control point. In the application to a refrigerator control, Fig. 3 (not shown), the compressor is driven by a series-wound motor supplied by an axle driven dynamo, and the field winding of the motor is paralleled by a variable resistance in series with The non-inductive resistance on the solenoid. The non-inductive resistance is normally short-circuited, but the short-circuit is broken by the relay at the predetermined temperature, thus increasing the resistance in parallel with the motor field winding and increasing the current in the field windings. In another modification, applicable to a shunt-wound motor, Fig. 4 (not shown) the shunt winding of the motor is in series with a variable resistance which is normally short-circuited, but is placed in the circuit by the relay switch at a predetermined temperature. The thermostatic device may have more than two contacts, and an embodiment of this device is described in Fig. 5, not shown.

Title: Improvements in feed rollers for ring spinning and doubling machines
IPC: B65H51/10
Filed: 1930-11-05
Abstract: 363,073. Stop motion for delivery rollers of ring and like frames. RUSHTON, H. and RUSHTON, H., Davenport Street Works, Macclesfield, Cheshire. Nov. 5, 1930, No. 33214. [Class 120 (ii).] In a ring spinning or doubling frame of the type in which the feed roller or rollers for each head are mounted with their axes perpendicular to the length of the frame and are driven independently from those of the other heads, the driven feed roller being mounted on a short shaft having dogs or teeth at its driving end to engage with corresponding teeth on a sliding gear wheel, a circumferential groove with an inclined face is formed on the sliding gear wheel and a rod with a tapered end is adapted to be moved into engagement with this face to disconnect the drive. One of the feed rollers A for a head of the machine is carried on a short shaft B journalled in a sleeve carried by a bracket C. The shaft B has dogs or teeth e<1> at its end to engage dogs or teeth d<1> on a gear wheel D. The teeth c<1>, d<1> are sufficiently deep always to remain in engagement. A coiled spring d tends to keep the bevel gear E on the wheel D in engagement with a bevel gear F on the main driving shaft. A circumferential groove d<2> with an inclined face d3 is formed in the wheel D so that vertical movement of the rod G with its tapered end g will cause the bevel gears E, F to become disengaged. The rod G is carried on a vertical rod K the upward movement of which takes place as the result of the breakage of a single thread passing from the creel to the spinning bobbin. Suitable mechanism for the actuation of the rod K is described in Specification 363,072. The short shaft B is preferably mounted in a fibre sleeve so that lubrication is unnecessary. If desired the top feed roller which is not positively driven may be carried in a swivelling bracket A<2> so that it may be swung to one side, or an adjustable bar may be substituted for the non-positively driven feed roller. A pair of friction wheels may be substitued for the bevel gear wheels E, F.
