Title: Continuous sulfonation process
IPC: C09K23/00
Filed: 1964-04-10
Abstract: Organic reactants are sulphonated by mixing a stream of the organic reactant with a stream of SO3 and gaseous inert diluent in a reaction zone for not more than 10 seconds to give a film of up to 0.04 inch thickness on a cooled surface in the reaction zone, whereby the temperature of the mixture can be controlled, then rapidly cooling the reaction mixture in a cooling zone. The organic reactant may contain an olefinic linkage, an aromatic nucleus, or an alcoholic hydroxyl group.  The product is separated and neutralized.  The product may be digested without substantial back-mixing to provide a product richer in sulphonic acid.  A sulphonatable organic reactant, e.g. a fatty alcohol, may be added to the mixture in the digestion zone.  The inert diluent may be air, N2 or CO2. Any mist present in the mixture of SO3 and diluent is removed before introduction into the zone.  The organic reactant is introduced into the reaction zone at the lowest practical temperature consistent with its being in liquid form.

Title: Improvements in or relating to devices for cutting sound records
IPC: G11B3/36
Filed: 1939-05-19
Abstract: 529,019. Sound recording and reproducing machines. V. G. MANUFACTURING CO., Ltd. May 19, 1939, No. 15006. Convention date, May 21, 1938. [Class 40 (ii)] Relates to devices for tracking a cutting head over a blank record disc or cylinder by means of an endless flexible traversing element, and consists mainly in the provision of a member permanently attached to the endless traversing element 1 and movable through a guide. In the machine shown, an endless steel band 1 is arranged over the turntable 10, passing over pulleys 2, 3, the pulley 2 being driven from a shaft 5 through worm gearing. The pulley 3 is mounted in a member 6 which is adjustable to control the tension of the band. The recording-head 11 is mounted on a counterweighted arm 17 which is pivoted to a strap 16 attached to the band 1. A block 15, secured to the band 1 at the same point as the strap 16, but on the opposite face of the band, is shaped to engage slidably in a groove 14 in a bar 12 fixed between the upper and lower parallel portions of the band. Thus, as the band 1 is driven it traverses the recording- head radially across the record-blank and the block 15 prevents vertical or lateral movement of the band and the recording-head. A recess 14<SP>1</SP>, similar to 14, is formed in the upper face of the bar 12, and the strap 16 may be made to surround the bar so that the block 15 can engage with the upper recess 14<SP>1</SP> instead of with 14. This arrangement enables an arm 17<SP>1</SP>, Fig. 2, carrying a reproducing pick-up 20 to be traversed across the record disc simultaneously with the movement of the recorder 11 and in the opposite direction, especially for the purpose of monitoring. The movement of the recording and reproducing heads can be stopped at any time by slackening the band 1. The endless traversing-band may extend over a number of turntables or like record supports, to provide an arrangement for recording and/or reproducing from a number of records simultaneously or in succession.

Title: Machine for harvesting root crops
IPC: A01D17/10
Filed: 1959-05-01
Abstract: 864,181. Harvesting root-crops. GUREL, S. Aug. 18, 1959 [May 1, 1959], No. 15029/59. Class 6(3). [Also in Groups II and XXX] A potato harvester has a cutter 23 Fig. 1, which removes haulms and foliage from the drill and a share 28 which digs the drill and feeds potatoes &c. on to a slotted elevator 29 where small stones and earth fall between the slats on to the ground. Potatoes, large stones and cut haulms and foliage fall on to conveyer 30 having square openings whereby potatoes and extraneous matter fall through the openings on to the lower run of an elevator 31, Fig. 4. Large stones, roots &c. remain on conveyer 30 and are discharged at the rear. Buckets 32 on the elevator 31, which are raised into position by a cam 34 engaging followers 33, Fig. 4, carry the potatoes and stones upwardly for discharge on to a downwardly inclined flight of a conveyer 35. Potatoes and round stones roll over a conveyer 36 to a conveyer 37, whereas flat stones are retained on conveyer 36 and are discharged at the rear. From conveyer 37 the potatoes and stones pass down slides 40 to two conveyers 38 and are then fed to the troughs 42 of a conveyer 41 which travels at a speed preventing bunching of the feed. The latter is fed to a similarly troughed conveyer 43 moving faster than conveyer 41 whereby the stones and potatoes are spaced apart along the troughs before being delivered to a conveying and separating device 47 whereby the stones are separated. Resilient fingers 45 Fig. 14 located in the paths of the feed from the troughs of conveyer 43 to the device 47 apply a braking effect to the potatoes and stones which fall singly on to them. From each trough of the conveyer 43 the singly fed stones and potatoes fall to a horizontal trough 52 comprised by resilient fingers 51 extending from the adjacent runs of two conveyer bands 48, Figs. 6 and 8. In the latter embodiment the bands engage sprockets 49 rotating about vertical axes ; in the embodiment of Fig. 11 the bands are engaged by sprockets 50 having horizontal axes. Thus, stones deflect the fingers and fall on to a transverse conveyer 55 whereas potatoes are carried by the finger to a transverse conveyer 56 which feeds them to an elevator. Conveyers 37, 38, 41, 43, 47, 55 and 56 are mounted in a frame 58 pivoted at 59 to the chassis for oscillation about a horizontal axis, to ensure that the various troughs do not tilt sideways when the harvester travels over undulating ground.

A set of tools is provided for each rail.
Patent GB-1589044-A (GB)
Title: Thermally stable cable
IPC: D07B1/02
Filed: 1978-04-18
Abstract: The heat-resistant cable comprises continuous glass filaments which, in the form of rovings (2) are helically wound one on top of the other at a constant helix angle (x) from the cable centre point to the outer surface and are bonded to one another in an elastomeric material. Upon heating, the thermal elongation of the filaments is counteracted by the simultaneous radially directed volumetric thermal expansion of the elastomeric material. As far as the overall length of the cable is concerned, the thermal elongation of the cable is opposed by the simultaneous increase in the cross-sectional area of the cable, so that the thermal elongation effects can be influenced, taking into consideration the thermal expansion characteristics of the reinforcing and elastomeric materials used, by controlling the helix angle (x) at which the filaments are wound one on top of the other such that, as desired, either expanding cables, contracting cables or cables of constant length are obtained. The thermal contraction effects induced upon cooling of the cable can likewise be influenced by controlling the helix angle. In the case of some applications, where the cable is subjected to high tensile loads, the helix angle (x) may be additionally brought into a relationship with the tensile load, with consideration of the modulus of elasticity of the filaments used. <IMAGE>
