Title: Process and apparatus for separating oil and aqueous phase in oil musts
Inventor: BUFANO DOMENICO
IPC: C11B3/00
Filed: 1968-05-01
Abstract: 1,213,068. Purifying vegetable oil. D. BUFANO. 1 May, 1968 [13 May, 1967; 22 July, 1967], No. 20536/68. Heading BID. [Also in Division C5] Vegetable oil extracted in a press A is pumped into a glass-walled tank 7, where the aqueous phase and solids settle to the bottom and are drawn off through valve 9a. Water containing 2.5% sodium chloride, is sprayed into the oil from sprayer 4 above the tank, washing solids from the oil, and after settling this water is drawn off through valve 9a. The oil is washed repeatedly in this fashion, pure water being used in the final wash. The water supply is maintained with valve 9a open, until the oil-water interface falls below the bottom of the middle section of the tank. Valve 9a is then closed and valve 9b opened to drain off the purified oil, before refilling the tank for a new cycle. Valve 9c is used for drawing off samples of aqueous phase in the first stage, to check how far the oil has separated therefrom. Separation may be aided by vibrating the tank and contents. The upper section of the tank is parallelpipedal, the other sections are cylindrical. The upper part of pipe 8, leading from pump 2, may be turned to fill either of two tanks 7 in turn.

Title: Improvements in or relating to piezo-electric pressure transducers
IPC: G01L23/10
Filed: 1960-06-10
Abstract: 947,063. Piezo - electric transducers. SCHWEIZERISCHE LOKOMOTIV - UND MASCHINENFABRIK. June 10, 1960 [June 12, 1959], No. 20580/60. Heading H4J. A piezo-electric transducer for measuring high-frequency pressure oscillations or shock waves is secured in a wall 15, and spurious outputs due to clamping stresses are avoided by providing a sleeve 21 between the wall and the transducer which is engaged by a clamping screw 19, the sleeve having a short stepped portion 21a which is pressure fitted on the transducer and has an axial length considerably less than that of the transducer housing 5. The limited area of transducer support by the stepped portion 21a substantially reduces the penetration of pressure variation transmitted from the wall, and the remaining parts 21b, 21c of the sleeve serve as very stiff supporting springs. The transducer comprises quartz bars 1, 2 and an intermediate electrode 8 which are fitted in a steel sleeve 3. A pressure membrane 6 integral with the steel sleeve is sealed to the transducer housing 5. The quartz bars are placed under initial stress by a steel cylinder 4 pressed into sleeve 3. A conductor 9 connects the electrode 8 to a contact member 10 mounted in an insulator, and a cavity 12 between the insulator and cylinder is packed with a drying agent.

Title: Improvements in bobbin doffing devices for spinning and twisting machines
IPC: D01H9/04
Filed: 1927-08-04
Abstract: 296,532. Hampe, R. Aug. 4, 1927. Doffing-arrangements; lifting-rails. -In a. flyer spinning and twisting machine in which only a single lifter rail is provided' which itself effects, the doffing of the bobbins, the full bobbins 3, Figs. 1 and 2, are doffed and the empty bobbins 23 placed on the spindles 1 while positively guided by the lifter-rail 5, pivoted at 8 on the lifting racks 9, and on which bobbin supports, e.g. felt braking-rings 4 are fixed. During spinning the parts are as shown in Fig. 1, each spindle 1 being supported in a footstep 22. To doff, the frame 12 is lowered and the arms 17 turned about the shaft 16 to bring the pegs 18 coaxial with the spindles 1, fresh empty bobbins 23 being placed on the pegs 20. The rail 5 is then lowered and turned about the shaft 8 to allow the bobbins 3 to fall on to the pegs 18, and the shaft 8 turned further so that the preferably forked, arms 7 strip any threads left on the spindle. The thread is cut by the member 19, comprising two comb-like sliding cutters, and the new bobbins 23 raised on to the spindle 1 by the rail 5. The action of the machine is independent of the position of the flyers 2. In a modification, open cylindrical carriers 18<1>, 20<1>, Fig. 6, for the full and empty bobbins, open at one side, are supported in groups by bridge members carried on vertical members 36<1> on a rail 36<11> adjustable vertically and horizontally by racks 36<1111> on a frame 86<111>. The lifter rail consists of arms 51 formed with crossheads 51<1> capable of passing through two adjacent members 18<1>, 20<1>.

Title: Master-slave manipulator
IPC: G21F7/06
Filed: 1963-05-23
Abstract: 1,048,262. Manipulators. AMERICAN MACHINE & FOUNDRY CO. May 23, 1963 [June 12, 1962], No. 20605/63. Heading B4Q. A manipulator of simplified construction in which movement of the master arm in the X, Y, Z directions produces corresponding movements of the slave arm comprises a support 19, a pivotal mount 20 for the support, and master and slave arms 26, 27, respectively, pivotally connected at 28 to the ends of the support. The mount 20 comprises a housing 21 secured to a wall 31 and supporting a pair of ball-races 22 having an annular space 41 therebetween. The ball-races 22 support a ball 23 secured to the support 19, a pair of guide pins 25 secured to diametrically opposite points of the ball being received in the space 41. The mount 20 permits X motion of the arms 26, 27, i.e. side-to-side motion in a plane parallel to the wall 31 and also Z motion of the arms, i.e. up and down motion as viewed in Fig. 1. During the X motion the pins 25 traverse the space 41 and in any position of the pins the support 19 may be rocked about their axis to obtain the Z motion. The engagement of the pins 25 in the space 41 prevents swivelling movement of the ball 23 which would prevent the application of a torque at the tongs 40 in a plane parallel to the X motion, e.g. when transferring articles from one position to another in a horizontal plane. The Y motion, i.e. motion of the arms in a plane perpendicular to the wall 31 is transmitted from the master arm 26 to the slave arm 27 by a system of pulleys and cables extending through the support 19 (Figs. 3-5, not shown). The tongs 40 are carried by a tube 52 rotatable about its axis for azimuth motion relatively to a non- rotatable tube 49 of the slave arm, this tube 52 being rotated by a corresponding tube 52 of the master arm carrying a handle 38, the motion being transmitted by a system of pulleys and cables. Wrist mechanisms 37, 39 of the master and slave arms and including differential gearing (Figs. 7, 8, not shown), enable the handle and tongs to be given an elevation movement and also a rotational movement relatively to the tubes 52, the tongs being opened and closed by a trigger 92. All these motions are transmitted by cables. A releasable ratchet (Figs. 9-11, not shown), holds the trigger in its set position. An alternative mount for the support comprises (Fig. 12, not shown), a ball 111 mounted on the support 24 by bearings 115, the ball 111 having a pair of pins 112 rotatable in bushings 113 in a flange 110 secured to the wall 31. Another mount (Fig. 14, not shown), comprises a pair of semi-circular members 126 clamped around the support 24 and pivoted by bearings 124 in an annular housing 123 rotatable by an annular bearing 120 in a flange 119 secured to the wall 31.

A wringer mop comprises a sponge 10 supported on two backing members 9, each of which is mounted on a separate hinge member 6 for folding to squeeze the sponge, pressure members 15 being pivoted on the hinge members coaxially with the backing members. The mop handle 2 is held by a split socket 3 provided in a centre fitting 1, which includes side cheeks 4 bent and joined together to form a rectangular end. On the outer corners hinge sockets 5 are formed to receive the hinge members 6, each of which comprises a length of wire bent into rectangular shape. The sides of the members 6 are of L-shape to pass behind the wooden backing members 9, each of which is attached to a separate metal plate 11 by means of a pin and wing nut 12. The outer ends of the plates 11 are bent up to form hinge sockets receiving the in-turned ends of the hinge members 6 ; each backing member 9 is free to pivot on the outer end of the corresponding hinge member 6, outward movement being limited by side flanges 14 formed on the plates 11. The ends 15a of a pair of pressure links 15 are bent to engage in slots in the plates 11, so being pivoted coaxially with the hinge members 6. Each pressure link 15 is pivoted to one arm of a V- shaped link 16 which itself pivots in a socket 18 formed in a slide 19 mounted on the handle of the mop. Tails on the plates 11 engage the centre fitting 1 to support the plates when in mopping position. The Provisional Specification refers to alternative constructions, in one of which the metal plates 11 are omitted, being replaced by suitably formed extended portions of the wire hinge-members 6. In this case the pressure members 15 are formed from sheet metal and have a curled socket at one end for pivoting to the hinge members. In another construction, the wire hinge-members 6 are replaced by L-shaped plates, a blade spring being fixed at one end to the underside of each plate, at its outer end, while the inner end of the spring bears on the backing member, being fixed to it by means of a pin and wing-nut. In a further modification, the handle is fixed to one of the backing members. Reference has been directed by the Comptroller to Specifications 744,251 and 697,400.
