Title: Timing device
IPC: H01H50/88
Filed: 1970-02-18
Abstract: 1298993 Dashpot-type delay timers AMERACE ESNA CORP 18 Feb 1970 [26 Feb 1969] 7833/70 Heading F2S [Also in Division H1] In a delay timer of the kind in which air flows at a controlled rate through a restricted orifice, the orifice is defined by a porous plug 112 and its flow cross-section is made adjustable by fitting an apertured shutter 122 over the plug's surface The shutter is rotatable about the axis of a screw 120 and the shape of the aperture 124 in it is as shown in Fig. 6, so that the unobstructed area of the plug 112 diminishes progressively as the shutter 122 is rotated. In use, as shown in Fig. 2, to control a switch 54, a solenoid 18 is energized to pull up an armature 20 and thereby raise, through a spring 70 and bush 32, a rod 30 which in turn raises a diaphragm 38 in the timer. This movement causes flow of air from the upper chamber 46 of the timer, through the porous plug 112 and by way of channels 126 and 128 to the lower chamber 48. The latter is closed, i.e. there is no connection to the ambient atmosphere. The switch 54, controlled by a snap-action spring 60-64, is operated by means of a bifurcated switch arm 52 engaged with the rod 30, the delay between solenoid energization and switch operation being determined by (a) the setting of the shutter 122 and (b) the initial position of the solenoid. The latter is adjustable in a vertical direction, its holding screws 162 being mounted in slots 164 for this purpose. On de-energization of the solenoid, the spring 70 assists the armature 20 to descend, carrying the rod 30 downwardly and compressing springs 92 and 102 in the timer. A valve element in the form of an elastomeric ring 86 has hitherto been sealed at its lowermost edge 88 to a ledge 96 on the rod 30. Compression of the springs 92 and 102 breaks this seal to open a flow path through the diaphragm and thereby allow rapid return of air from the lower to the upper chamber, thereby (a) releasing the switch and (b) recharging the upper chamber for the next cycle.

Title: Improvements in reels of the kind on which yarn is wound temporarily for treatment and is automatically laterally advanced along the reel
IPC: B65H54/58
Filed: 1933-03-15
Abstract: 400,501. Reels for simultaneously winding and delivering yarn. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. March 15, 1933, No. 7859. Convention date, March 15, 1932. [Class 120 (ii).] A reel mechanism of the type on which yarn is wound temporarily and is automatically laterally-displaced, is provided with means for controlling the rate of lateral displacement of the yarn. The reel comprises two sets of bars mounted on discs, the discs of one set being inclined and mounted eccentrically to those of the other set, several methods of adjusting this eccentricity and/or inclination being described. The hub 5, Fig. 1, carrying one set of longitudinal bars is mounted on a bush 2 whose eccentricity and inclination to the shaft 1 may be adjusted by means of the screws 9, 10. In a modification, Fig. 2, means are provided for adjusting the inclination of the hub whilst the reel is rotating. The stationary hollow axle 1 has two diametrically opposite slots which slidably accommodate two bearing pieces 4 having inclined shoulders 7. The bearing pieces are screw-threaded internally and engage a screwed portion 3 of the shaft 2, so that they may be axially displaced by rotating the handwheel 5. Upon axial displacement, the inclined shoulders 7 cause the eccentric bush 6 to rotate about a transverse pin 8, whereby the inclination of the hub 11 is altered. In a further modification, Figs. 11 and 12, one pair of hubs is mounted on the axle 1 and is rotated by means of the pulley 3, whilst the other pair 5, 5 are pivoted on pillars 7 mounted on turntables 8, the latter being rotated and the relative inclination of the two pairs of hubs altered by turning the hand-wheels 10, which displaces a radial arm 9 mounted on one of the turntables 8. The hand-wheels may be provided with a pointer and graduated scale. Specification 3831/11, [Class 15 (i), Dyeing &c., Apparatus for], is referred to.

Title: X-ray spectrometer apparatus
IPC: G01N23/207
Filed: 1964-02-25
Abstract: 1,043,374. X-ray diffraction apparatus. HITACHI Ltd. Feb. 25, 1964 [April 5, 1963], No. 7863/64. Heading H5R. In order to ease construction difficulties, e.g. by the reduction of the spacing between the components, of an X-ray spectrometer in which the X-ray source and the curved diffracting crystal are arranged to be on the circumference of a Rowland circle, the detector is positioned in the path of the diffracted X-rays, near to the crystal instead of on the circumference of the Rowland circle. The spectrometer system may be of a linear or a rotation type. In the first, the specimen 1 (Fig. 2) is fixed, a beam of accelerated electrons a being directed on to it to produce characteristic X-rays, in a diverging beam, in a direction b. The diffracting crystal 2 is positioned at some point on the straight line in the direction b and on the circumference of a Rowland circle through the source 1. Instead of positioning the detector 3 on the circle where the diffracted rays are focused, it is placed as near to the crystal 2 as is convenient. The overall size of the spectrometer is thus reduced which is advantageous in the production of a high vacuum in the spectrometer vessel. The close positioning also provides a higher intensity of X-rays at the detector, and allows simplified construction and direct reading of wavelength. In the rotation type (Fig. 4, not shown), the above advantages are obtained although the apparatus is not as compact as the linear type. The crystal is positioned at some point on the circumference of a fixed Rowland circle through a fixed specimen, while the detector is positioned in the path of the diffracted rays nearer to the crystal than the circumference of the circle. The crystal used may be of the Johann or Johanson type whose radii of curvature are respectively twice, and equal to, that of the Rowland circle.

Abstract: 931,416. Laminates. BENDIX CORPORATION. March 3, 1961 [March 11, 1960], No. 7929/61. Drawings to Specification. Class 140. [Also in Group XXII] Two elements, at least one of which is rigid, are hermetically sealed together by coating one or each of the mating surfaces of the elements with a dispersion of thermoplastic synthetic resin, heating the coated surface or surfaces to fuse the thermoplastic coating thereto, allowing the coated surface or surfaces to cool, putting the elements together, heating again to re-fuse the thermoplastic coating until a bond has been formed between the two elements and then recooling the whole. The thermoplastic synthetic resin may be polyethylene or polypropylene. The second heating step may be performed by induction heating. The method is applicable to the bonding of metal to metal, thermoplastic synthetic resin or glass, or thermoplastic synthetic resin to thermoplastic synthetic resin It is useful where the elements are subjected during assembly to stresses that would tend to create strains in the bonding material.

Title: Battery charging system more particularly for sealed cell batteries
IPC: H02J7/00
Filed: 1968-02-19
Abstract: 1,211,439. Battery charging systems for sealed cells. GENERAL ELECTRIC CO. 19 Feb., 1968 [28 April, 1967], No. 7948/68. Heading H2H. A battery-charging system for sealed rechargeable batteries comprises means whereby the battery is charged at a rapid rate until the battery acquires a predetermined voltage whereupon the charge is interrupted or reduced to a " trickle " charge, such interruption taking place only between pulses of charging current. Means may also be provided to render the control sensitive to the temperature of the battery. A battery 110 is charged from an A.C. supply 118 by way of a thyristor 130 and a reed relay assembly 134. During the initial, rapid charging, operation the contacts 152 of the reed relay are open and the thyristor 130 fires to supply a pulsed D.C. to the battery 110 during the alternate half-cycles of the supply 118 having the requisite polarity. During each current pulse, the current through the current coil 150 of the reed relay maintains the contact 152 open but as the battery voltage approaches a predetermined value the voltage coil 154 of the reed relay, which senses the battery voltage, becomes more and more effective until, at the predetermined voltage, it causes contacts 152 to close, thereby inhibiting firing of the thyristor 130 to interrupt the rapid charging. The fluxes in the coils 150, 154 of the reed switch are arranged so that the contacts 152 can only be closed to terminate rapid charging in the periods between charging current pulses. A thermistor 114 is provided to make the charging operation dependent upon the battery temperature and, if desired, a further thermistor 156 may be included in the reed relay assembly to compensate for temperature changes in the assembly. After the thyristor has been rendered non-conductive trickle charging is provided by a diode 144 and resistor 148 in shunt with the thyristor. In other embodiments the contacts of the reed relay may be normally closed and placed in series with the rapid charging circuit; the reed relay may be replaced by a transistor and finally the firing of the thyristor may be inhibited by means of a second thyristor which becomes conductive when the battery voltage becomes sufficient to cause breakdown of a Zener diode.

Abstract: 1,212,385. Sealing. STANLEY WORKS. 19 Feb., 1968 [21 Feb., 1967], No 7956/68. Heading B6P. [Also in Divisions B3, B8 and F2] A strapping machine (see Division B8) for guiding and looping a band e.g. of plastics around an article by feeding it through a guide track, tensioning -and sealing the loop by a metal clip 154 and severing it from the remaining band comprises means for temporarily twisting the strap through 90 degrees at a sealing position.  A shoot 74 guides the band through a metal seal 154 located between toothed jaws 150, 152. The band then passes through a guide 17 which twists the band through 90 degrees before it enters the track 14 (on the right of Fig. 2). Passing around the track it enters an auxiliary drive mechanism 270 (Fig. 14, not shown) which pulls the band, to prevent buckling, in the track and also guides the band into a guide 19, which rotates the band through 90 degrees in the opposite direction. The jaws close sealing the loop and the band is severed. The metal clips 154 are fed from the base of a magazine 159, Fig. 11, projecting at right angles to the side of the article on which the loop is sealed, by an oscillating stripper 162. The jaw 152 is operated by a pneumatic cylinder and linkage means 196-200. A reciprocating plate 168 (see also Fig. 2) advances to hold the clip between spaced fingers 166 during band feed. The jaw 152 includes spring loaded side members 212, 214, Fig. 12, flanking a replaceable crimping element 207. The members 212, 214 crimp the longitudinal ends of the seal while the element 207 deforms the central portion. The loop ends may be joined by welding instead of a separate seal (not detailed).

Title: Improvements in or relating to the bottling of carbon dioxide containing beverages
IPC: C12H1/18
Filed: 1960-03-07
Abstract: In bottling carbonated beverages containing albumen, the beverage, e.g. beer, while maintained under high pressure, is first sterilized or pasteurized by heating, and before passing to the pressure filling machine, is cooled to a temperature sufficiently low to avoid coagulation and precipitation of the albumen when the filled container, e.g. bottles, are removed from the pressure filling machine.  Any difference in temperature between the bottle and the beverage at the time of filling should be sufficiently small, e.g. not greater than 35 DEG  C., preferably from 25 DEG  to 30 DEG  C., to preclude release of carbon dioxide from the beverage and bottle cracking.  At the time of filling, i.e. after preliminary hot water washing and U.V. irradiation, the temperature of the bottles is preferably within the range 55 DEG  to 65 DEG  C.  The apparatus used is suitably that described in Specification 842,809 modified by the inclusion of a cooler arranged between the heater and filling machine.  Both heater and cooler are preferably closed plate-type heat exchanger systems and the filling machine used may be that described in Specification 482,285.

Abstract: 1499437 Scoring gum sheets PACKAGE MACHINERY CO 26 Feb 1975 [25 April 1974] 8019/75 Heading B5A [Also in Division B8] Sheets of gum 12 are fed along a first path 20 where they are scored along lines 25 parallel to the first path by a scoring device 24 and then along a second path 28, lying normal to the first and comprising two portions at different elevations, where the slabs 26 formed in the first scoring are separated by separating device 30 between the two portions of the second path, and are scored along lines 33 parallel to the second path by scoring device 32, the scored slabs 2611 then being loaded on to a conveyer travelling normally to the second path for transference to a wrapping machine 10. Preferably, all the operations on the second path are performed in timed relation with the wrapping machine and controlled by a single drive mechanism; similarly, supply of sheets to the first path and the operations thereon are synchronized by being controlled by a single drive mechanism, which is activated by a sensing means along the second path responsive to the movement of gum therealong. A conveyer 38, Fig. 1, moves a tray carrying sheets of gum from the bottom of a stack of trays 12 to an unloading station 16 where a sheet is lifted off by a vacuum transfer mechanism 40 and placed in the first position 18 where it is accurately located by pushers 45. The sheet passes through upper and lower scoring discs 50, which also trim the selvedge, to the second position 22 where it engages locating stops 56. A chain conveyer 58 carries the scored sheet to an elevating member 62 which accommodates one slab 26<SP>1</SP>. The member 62 is raised and severs the slab 26<SP>1</SP> from the remainder of the sheet 26 against a shearing edge 64. When the separated slab is level with the second portion of the second path 28 a pusher 70 feeds it to an alignment device 74 (Fig. 1) and through a second set of scoring discs 82. Deflectors 82 remove selvedge as the scored slab 26<SP>111</SP> is fed beneath hold-down fingers 86, 88 to another pusher 90 which feeds the slab on to a conveyer 92 leading to breaker wheels 37 for separating the scored slab 26<SP>11</SP> into gum sticks.

Abstract: 472,172. Making sheet glass. PILKING- TON BROS., Ltd., and JOLLIE, A. March 17, 1936, No. 8023. [Class 56] Relates to the method of making sheet glass in which a sheet 1 is drawn continuously from a mass of molten glass 2, and in which the width of the sheet is maintained by pairs of driven rollers 4, that engage the edges of the sheet, rolled bands 5 which are thicker than the body of the sheet being formed at the edges. According to the present invention, the thickness of the portions of the sheet immediately adjoining the rolled bands 5 is controlled by varying the distance from the side walls 8 of the drawing-pot at which the edges of the sheet rise from the glass 2. The distance is varied by adjusting the position, in the direction of the plane of the sheet, of members 9 that engage the extreme edges of the rising glass. Each of the members 9 consists of a bar or narrow plate, and the part engaging the glass may be straight or it may be a semicircular notch. The member is attached to a bar 12 adjustably fixed to a support 15. Specification 467,580 is referred to.

Abstract: 248,193. Pollak, J. E., (Piepmeyer & Co., Kommanditges). March 25, 1925. Electromagnetic switches; switches, locking and unlocking; thermal switches. - Relates to means for regulating temperatures, water levels, &c. of the type described in Specification 232,917 in which the rise or fall of temperature, e.g. connects a source of current to one or other of two conductors 24, 25 thereby completing a circuit to an electromagnet 19 and actuating a core 2 so as to break the circuit through the conductor 24 or 25 and also so as to break or make a circuit such as 13 to a heating device. According to the arrangement shown in Fig. 1, the core 2 carries in addition to the contact 13 a bridging contact which connects a divided contact 16 either to a contact 17 or to a contact 18. The core 2 also carries collars b, c which are engaged by an armature d adapted to be attracted out of their path by a locking magnet M. When the temperature rises sufficiently a circuit is completed through line 24, contacts 17, 16 and magnets M, 19. The armature d is attracted allowing the core 2 to be attracted and causing the heating circuit to be broken at 13 and the bridging member to move so as to connect contacts 16, 18. The magnet M serves to prevent operation if the current is insufficient to cause the core 2 to move the full distance, i.e. through the centre of the magnet 19 to a corresponding position on the right. When the temperature falls, a circuit is completed through line 25 and contacts 18, 16 and the core 2 is pulled back into its original position. According to a modification, Fig. 4, the magnet 19 is connected in parallel with the magnet M through contacts 51, 52, the former of which is connected to the armature d so that a circuit is not completed through the magnet 19 till the locking armature d has been attracted. According to the arrangement shown in Fig. 3, the armature 2 is connected by a spring 39 to a switch the contact arm 44 of which is moved alternately from one position to the other by successive pulls on a member 40. With the parts in the position shown a circuit is completed through a heating winding 36 but when the temperature becomes excessive a capsule 35 expands and tilts a case 31 so as to bring a contact 22 into engagement with a contact 21 and so complete a circuit through the magnet 19. The core 2 is attracted and the arm 44 moved into its dotted-line position, breaking the circuits of the heater 36 and of the magnet 19. When the temperature falls, contacts 21, 23 engage, the core 2 is again attracted and the arm 44 restored to its original position.
