Filed: 1921-08-23
Abstract: 189,211. Percival, S., (Brostrom, C.). Aug. 23, 1921. Addition to 142,903. Folding edges of sheet material.-In the machine claimed in the parent Specification for folding the edges of sheet material, such as the edges of shoe vamps, cloth, &c., and producing snipping cuts at will in the material, there are provided means for moving the material laterally progressively into the path of the snipping means to produce cuts of varying depth, a device for gauging the edge of the material in accordance with its contour, a fold-presser having a curvilinear face adapted to roll progressively over the folded material, and feeding-devices mounted on an oscillating support. The material 2, Fig. 16, to be folded is passed over a support 8, a turnedup portion 24 of the material being retained in the position shown by a gauge 32 when straight or convex portions are to be folded. When concave portions are to be folded, the support 8 is raised into the position shown in Fig 20, the gauge then allowing the edge of the material to be snipped between a cutter 30 fixed to the frame of the machine and a reciprocating cutter 28, the depth of the cuts in the edge of the material being determined by the distance through which the support is raised. The material is fed by a feed-point 6 and a feed-block beneath the material. The feed-point normally presses the material bv means of a spring, and is pivoted on an oscillating support carrying the feed-block. A diagonally-disposed plunger is mounted in the support and is operated by an eccentric to rock the support and periodically to raise the feedpoint. The feed-point 6 has an extension 370, Figs. 27 and 28, for engaging the edge of the work, and an inclined face 220 adapted to cooperate with a plough 218 to grip the partially folded material during the movement of the feedpoint and plough towards the fold-presser. The plough is rocked about a vertical pivot on the oscillating support 76 by a projection 206 on the plough adapted to engage alternately a spring and a screw secured to the frame on opposite sides of the projection. The return movement of the plough initiates the fold in the material. The fold-presser 10 has a curved edge 136 to roll over the fold 12, Fig. 18, and is mounted in a cylindrical bearing 130 in a spring-pressed lever. The presser is oscillated in its bearing by a reciprocating link 120. During the operation of the presser, the material is held tightly by a spring-controlled retainer 232, which periodically presses lightly on the material to allow it to be turned round and is raised during the operation of the feeding- devices. The feeding and folding elements are all arranged on a removable pivoted frame.

[Class 56] [Also in Group XII] In the manufacture of glass by the continuous process wherein the glass is melted, fired and conditioned to working temperature, a heating means, external to the glass and appropriate to the working temperature, is operative throughout the various operations and the extra heat required for the final melting and fining is obtained by the simultaneous passage of electric current in the body of the glass. In the form shown in Fig. 1, the constantly acting heating means comprise gas, whilst the extra heat in the final melting and fining compartment 3 is obtained from the passage of current between immersed electrodes 7. In this form, the pre-melting takes place in a compartment 2 and the conditioning in a compartment 4. In another form, Fig. 5, the pre-melting takes place on an inclined slab 15 extending across the gas-heated space surrounding the final melting, fining and conditioning compartments. In a third form, several pots are housed in a common gas-heated furnace, each pot being divided into two compartments, one for melting and fining and the other for conditioning. A water-cooled carbon electrode 7 as shown in Fig. 5 may be used for the final melting and fining. Specifications 597,678 and 597,838 are referred to.

Title: Improvements in pipe joints
IPC: F16L13/12
Filed: 1971-04-19
Abstract: 1276998 Pipe joints FORSHEDA GUMMIFABRIK AB 19 April 1971 [2 March 1970] 22700/71 Heading F2G A spigot-and-socket joint having a packing ring 16 of rubber is stiffened by means of a supporting ring 17 which comprises a pair of rings 18, 19 which mutually interact at generally tapered surfaces 20, 21 so that when the inner ring 19 is forced axially into the outer ring 18, the rings press radially against spigot and socket walls 14, 15. In the embodiment shown, the pipe socket and spigot are of cast iron. The outer ring 18 has a flange 24 which abuts the end of the socket 11 and the surfaces 20, 21 have annular ridges of a hook or barb shape (22, 23) (Fig. 2, not shown) to allow easy relative motion of the rings in the direction in which the joint is tightened but relative motion in the opposite direction is resisted. The rings, which are preferably of plastics material, may be split in at least one place to allow them to be opened out and snapped around the pipe spigot prior to insertion into the socket. A tendency for the supporting ring 17 to roll out of the annular space when the joint is simultaneously bent and rolled is inhibited by the frictional engagement of further annular ridges 25 on the outer ring 18 with the socket wall.

Abstract: 1,074,464. Protecting transistor circuits. AEG-ELOTHERM G.m.b.H. May 28, 1965 [May 30, 1964], No. 22835/65. Heading H3T. [Also in Division H2] In a spark erosion machine having a control transistor 3 which is pulsed to produce successive discharged across the gap 5 between an electrode and a workpiece, means are provided for monitoring the current flowing through the transistor in the intervals between pulses. As shown, the voltage across the emitter resistor 2 is applied through a resistor 8 to the base of a transistor 9. Pulses from a timing generator (not shown) are applied to the base of the transistor 3 and to the collector of the'transistor 9, the pulses being timed so that the transistor 9 can conduct only in the intervals when the transistor 3 is not pulsed, providing the voltage produced across the resistor 2 by leakage or short-circuit current is sufficient. A relay 11 is energized when the transistor 9 conducts and is effective to interrupt the supply and may also cause an alarm to be operated. Should several control transistors 3 in parallel be used, connection from the resistors 2 to the resistor 8 is effected through isolating diodes 7.

Abstract: 1483705 Rotating head magnetic tape apparatus INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [30 Sept 1974] 22876/75 Heading G5R A rotating magnetic head tape recorder has a magnetic head 18 on a rotor 16, a stationary mandrel 12A, 12B to support a magnetic tape across the path of the head 18, this path extending obliquely to the longitudinal edges of the tape, the tape being supported on the mandrel and rotor by air bearing means which lifts the tape from the head, and pneumatic means to selectively generate an additional air flow locally of the head 18 to lift the tape further in the vicinity of the head, the additional air flow escaping between the tape and mandrel 12A, 12B along a wave (22), Fig. 1 (not shown), formed by such air flow in the tape from the head 18 to the edges of the tape and travelling with the head 18. Rotor 16 is located between two stationary halves 12A, 12B of the mandrel and during read/  write operations the tape flies at low height above head 18, an air bearing for the tape at the rotor being provided hydrostatically by pressurized air supplied via channels 46, 48, 50, 52 to apertures (24), Fig. 2 (not shown), in a foil 54 of rotor 16, or hydrodynamically due to motion of the rotor 16 in the manner described in application no. 21138/75. During non read/ write periods the pneumatic means is operated to locally lift the tape further away from the still-rotating head to decrease wear. The pneumatic means comprises channels 58, 62, 64 leading from the air source supplying the rotor air bearing to a channel 26 around head 18 in the rotor foil 54, or to a jet (38), Fig. 4 (not shown), in front of the head, or to chamber (30), Fig. 3 (not shown), extending through the head to holes or longitudinal slots (34) in the working face thereof. The head 18 may have a convexly rounded and longitudinally slotted working face as described in application no. 21139/75. In order that the additional air flow locally of the head only flows therefrom between the tape and mandrel, back pressure is created by maintaining close tolerances between the rotor and mandrel, e.g. at edge 49, by a labyrinth seal provided by rotor notches 70 and mandrel lips 72, and by pressure in chamber 48 and in the interior 69 of mandrel half 12B which has a plate 68 closing its upper end.

Title: Improvements in or relating to the extraction of hecogenin
Inventor: PATES EDWARD WILLIAM
IPC: C07J75/00
Filed: 1954-08-09
Abstract: Hecogenin is extracted from crude materials, containing waxes and coloured impurities, arising from the preliminary hecogenin extraction of vegetable materials containing hecogenin, by means of a hot liquid hydrocarbon consisting predominantly of aliphatic hydrocarbons containing from 6 to 12 carbon atoms, the resulting solution of hecogenin containing impurities in suspension is treated with sufficient water to precipitate suspended solids, and the supernatant hydrocarbon liquid containing hecogenin is separated off. Suitable hydrocarbon solvents may contain a minor proportion, for example 10 per cent v./v., of aromatic hydrocarbons, petroleum fractions-particularly those boiling within the range 100 DEG  to 120 DEG  C. being the preferred solvents. The crude material used for the hecogenin extraction may be substantially free of wax, e.g., the crude material may be extracted with one of the above hydrocarbon solvents in the cold to extract wax without removing hecogenin to any appreciable extent, and the resulting substantially wax-free crude material may then be treated by the above process-preferably using the same hydrocarbon solvent as that used for the wax extraction. The sludge remaining after the separation of the supernatant liquid may be treated with a further quantity of the hot liquid hydrocarbon under such conditions that water absorbed or entrained by the sludge is continuously removed, e.g. under reflux conditions with water removal by means of a continuous decanter, in order to resuspend the sludge solids in said solvent and to dissolve remaining hecogenin therein, sufficient water is then added to the suspension to precipitate the suspended solids and the supernatant liquid containing the hecogenin is separated off. In the further treatment of the sludge, it is preferable to carry out the precipitation in the presence of a substance which lowers the surface tension of water, e.g. a lower alcohol such as ethyl alcohol, or a surface-active agent, in order to facilitate sludging of suspended solids.  The process is particularly suited to the crude hecogenin material which is the water-insoluble organic fraction arising from the saponification of hecogenin-containing vegetable matter, e.g. sisal. A number of detailed examples are given.

[Also in Group XVII] Sheets, cards, &c. are fed in succession on to a platform along which they are moved towards a suction station by a conveyer provided with means for spacing them at definite intervals along the platform, and each sheet is transferred in turn at the suction station from the platform to a partially completed package, supported in a package-forming apparatus, by a suction head operating in timed relationship with the conveyer and the formation of the packages. As applied to the feeding of cards into tobacco packages during their formation, the apparatus comprises a magazine 12 for cards 11, a reciprocating suction plate 13 which separates the bottom card from the stack and deposits it on a forked transfer table 26 which is rocked about a pivot by a link 28 so that the table is inclined and forms a continuation of an inclined platform 29, and a conveyer chain 36 provided with card-engaging abutments 37 for feeding the card along the platform. The table 26 and platform 29 are slotted to receive the abutments 37. The platform 29 is also reciprocated along guides 33 to feed the foremost card thereon beneath a plunger 31 having a convex-faced suction head 39 which grips the card and, when the platform recedes, the plunger is operated to carry the card (and a charge of tobacco) down a feed channel 42 and deposit it on top of the charge of tobacco in an open-topped packet. When the card is released by the convex face 39, the inherent resilience of the card causes it to spring clear of the face. The platform 29 and suction separator 13 are reciprocated by a common pivoted lever 19 operated by a cam 23 in synchronism with the operation of the packetwheel.
