Title: Braking system for road vehicles
IPC: B60T1/06
Filed: 1974-01-31
Abstract: 1449381 Control of A.C. motors M BAEKMANN 31 Jan 1974 [2 Feb 1973] 04529/74 Heading H2J A braking system for a road vehicle comprises a three-phase induction motor for each wheel 10 to be braked, with its stator 8 secured to the stationary part of the vehicle and its rotor 9 (which may be of squirrel-cage or disc type) connected to rotate with the wheel, and a threephase generator 5 driven by the vehicle engine 1 through clutch 2 and gear box 3 and having its output connected to the stator windings of the motors, whereby energization of the generator produces in each motor a magnetic field rotating in a direction opposite to that of the wheel to cause braking of its corresponding rotor. Each stator may have a three-phase bipolar drum winding whose coils are arranged and spaced by 120 in known manner, Fig. 2 (not shown). A typical braking operation is described, with variation of braking force by adjustment of the generator output through variation, in known manner, of the relative position of two or more separated pole rings on its stator or rotor, which rings are movable by up to one pole pitch using electrical, hydraulic, pneumatic or mechanical (e.g. a Bowden cable) means. The generator stator is stationary with the vehicle and its rotor is driven by a cardan shaft 6 coupled to a differential gear 4. The electrical braking by members 5, 8, 9 may be augmented by a friction braking system. The currents in the motor stator windings are limited by resistors 12 or thyristors (not shown), the resistors if used being located in a cooling air stream produced by motion of the vehicle. If the vehicle is associated with trailers, its generator may supply further induction motors mounted on these trailers to brake them.

Title: Improvements in or relating to hydraulic presses and control means therefor
IPC: B30B15/24
Filed: 1954-02-16
Abstract: 758,480. Forging presses. UNITED ENGINEERING & FOUNDRY CO. Feb. 16, 1954 [Feb. 16, 1953], No. 4557/54. Class 83 (4). [Also in Group XXIX] A die-forging press is provided with means for ensuring parallel movement of a platen. A press has a platen 14 movable towards a fixed platen 11 by single-acting pistons. Double-acting pistons 18a, 19a, 21a, 22a for effecting the return movement are provided at the corners of the platen 14 and slide in cylinders fixed to the platen 11. Diagonally opposite pistons 18a, 21a are fixed to racks 18c, 21c which mesh with pinions 18d, 21d, connected to opposite sides of a planetary gear 23. Pistons 19a, 22a in like manner are connected to opposite sides of a similar planetary gear. During a working stroke of the press suppose, for example, the platen 14 tilts so that the corner associated with piston 18a moves more rapidly than the opposite corner. A ring gear 23a of gear 23 is then rotated in such a direction that a valve 29, to which it is operatively connected, is moved to the left. Liquid under pressure is admitted to a chamber 31a and exhausted from a chamber 31b, of a cylinder 31, thus moving a piston 32 to the right. The end 32b of the piston 32 moves further into a cylinder 37 and the pressure above piston 21a and below piston 18a is thus increased and the platen 14 is brought parallel to platen 11. To effect the return stroke of platen 14, valves 53, 54, 55 are adjusted to admit liquid under pressure from an accumulator to the cylinders below pistons 18a, 21a, the liquid above the pistons passing through valves 46, 51 to exhaust.
Patent GB-759143-A (GB)
Title: Improvements relating to detergent compositions
Inventor: WILSON MARGARET ANNE ANDERSON
IPC: C11D3/30
Filed: 1953-02-19
Abstract: A detergent composition comprises an ionic detergent and an alkyl mono-amine which enhances its detergent properties, the amine having only one alkyl group containing 7 carbon atoms or more.  The amine may be a primary secondary or tertiary amine and the alkyl group containing 7 or more carbon atoms may be a straight or a branched chain and preferably contains 7-12 carbon atoms.  The amine may contain one or two alkyl groups containing less than 7 carbon atoms. Examples of suitable amines are n-heptyl, octyl, decyl and dodecylamine, and also dimethyl-n-decylamine.  The ionic detergent may be soap or a synthetic detergent, particularly a synthetic anionic detergent such as an alkylaryl sulphonate such as sodium dodecylbenzene sulphonate or a primary alkyl sulphate such as sodium lauryl sulphate or sodium cetyl sulphate.  The detergent may on the other hand be a cationic detergent such as cetyl trimethyl ammonium bromide or cetyl pyridinium bromide.  The amine may be dissolved in an aqueous solution of the detergent or, if not readily soluble, may be dissolved in the form of its more readily soluble salts, especially the hydrochlorides, the amine being then liberated from the salt by the addition of an alkali such as sodium carbonate.  The amine may be applied to the material to be cleaned, e.g. in the form of an aqueous solution of the free amine or of a salt thereof prior to applying to the material an aqueous solution of the ionic detergent.  If the material is to be subjected to a process involving the application to the material of a substance which is subsequently to be removed, e.g. the application of oil to wool during its processing, the amine may be incorporated in the substance, e.g. oil, prior to its application to the material so that the subsequent removal of the substance from the processed material by means of an aqueous solution of an ionic detergent may be facilitated.  In the above procedure the proportion of amine may be about 1/4 -1 per cent of the weight of the detergent and when directly incorporated in the detergent solution may be about 3-20 per cent of the weight of the detergent.  In an example woollen fibres cut into short lengths and extracted with ether and alcohol are impregnated with 3.6 per cent by weight of liquid paraffin and 2 grams of the impregnated fibres agitated for 3 minutes at 60 DEG C. with 300 cc of an aqueous solution containing 0.25 per cent of a mixture of 40 per cent by weight of sodium dodecylbenzene sulphonate and 60 per cent of sodium sulphate, 0.1 per cent of sodium carbonate and 0.1 per cent of n-octylamine hydrochloride.  The woollen fibres are then filtered, and washed twice with water and the percentage of residual liquid paraffin (based on the amount originally present in the impregnated fibres) determined by extraction with ethyl ether.  It is found that this percentage is 2 compared with 39 when the same procedure is followed with the amine omitted.

Title: Improvements in or relating to moulding from paste-like materials and presses therefor
Inventor: SORBIER PIERRE
IPC: B27N5/00
Filed: 1969-01-28
Abstract: 1,245,692. Compression moulding of wood pulp. P. SORBIER. 28 Jan., 1969 [29 Jan., 1968; 29 July, 1968], No. 4745/69. Heading B5A. Articles are made from paste like material e.g. wood pulp and binder by delivering a charge of material into a moulding tunnel closed at one end by a movable insert and advancing a two part piston in two stages along the tunnel to press the material against the insert. Moulding material is fed from hopper 8 into the tunnel 7. Insert A 1  closes one end of the tunnel and the other is closed by a two part piston comprising pistons 10 and 11. Two horizontally opposed pistons 17, 18 and a vertically acting piston also operate to compress the moulding material. The operation of the apparatus in moulding the end for a box having a flat portion and a surrounding rib is shown in Fig. 9 from which the tunnel has been omitted. Piston 10 first moves in the direction of arrow 20 to form the flat portion of the box end against insert A 1  which is held in position by stops 15. Side and base plungers 16, 17 and 18 are moved in to define the rib portions and these portions are compressed to their final density by part 11 of the composite plunger. Plunger 10 has an outstanding rib which forms a groove in the moulding to co-operate with a rib 12 on the adjacent insert A 2  in the curing tunnel. The plungers 16, 17, 18 are withdrawn, stops 15 are raised and the plunger 10 forces the insert A 1  and moulding 1, together against the previous moulding and into the curing or drying tunnel 24. At the end 30 of the drying tunnel 24, the end moulding and insert A 6  are separated from the others by a plunger 27 with a wedge shape head which engages projections 25 on the inserts A. The moulding is separated from the insert and removed by conveyer 32 and the insert is pushed by plunger 33 on to conveyer 35. The insert is moved along conveyer 35 in the direction of arrow 36, until it is fed back to the moulding tunnel 7 by plunger 40; the drive of belt 35 incorporating a slipping mechanism so that it advances an insert to position A 9  only when the previous insert and the plunger 40 are clear of the conveyer. In another embodiment (not shown) the whole of a box is moulded in one operation, the hopper being moved laterally to the right and a feed plunger supplied so that a pressing plunger acting vertically downwards on the moulding may also be used. The insert is made in two relatively slidable parts to assist ejection of the moulded article.

Title: Devices for machining cylindrical and tapered holes
IPC: B24B41/00
Filed: 1974-02-04
Abstract: 1440898 Grinding KUIBYSHEV ZAVOD KOORDINATNO - RASTOCHNYKH STANKOV 4 Feb 1974 05036/74 Heading B3D A device for machining cylindrical and tapered holes comprises a rotating tool 18, such as a grinding wheel, which effects a planetary movement and reciprocates along the axis D-D of the planetary movement, the tool being mounted on a carriage 15, 16 linked to a pusher 42 rotatable with the carriage and movable along the axis for imparting radial feed to the carriage by a drive from a member 35 having a master from which can be set at various angles to the axis, the member engaging a rod 33 reciprocatable along the axis with the carriage and movable by the member perpendicular to the axis, the rod being linked to the pusher member so that the movement of the rod perpendicular to the axis causes movement of the pusher along the axis. The device may be an integral part of a jig-grinding machine or consist of a separate unit fitted to a jig-boring machine having a rotating and reciprocating spindle. In the former case, the headstock 7 of the machine supports a sleeve 12 vertically reciprocated by a drive from a shaft 21 having a gear 20 engaging a rack 19 formed on the sleeve. The spindle 13 is mounted in the sleeve and rotated by gearing 24, 25 from a splined shaft 26 driven by a mechanical drive or by a manual drive having a gear 27. A nut 29 is rigidly secured to the spindle 13 and engages a hollow screw 30 which is formed with gear teeth 31 engaging a rack in the rod 33. A roller 34 on the rod engages the master form 35 which is adjustable on a member 37, in turn, carried by a rod 41 movable by rack-and-pinion gearing 38, 40 from a drive shaft 39. The pusher 42 is keyed to the spindle 13 and rotatable in but axially locked to the hollow screw 30 so that rotation thereof by movement of the rod 33 displaces the pusher 42 axially of the spindle to cause an inclined surface 44 to act on a follower 46 and cause radial movement of a slide 15 along a guideway on the lower part 14 of the spindle. The grinding wheel 18 is mounted on a spindle 18 carried by a further slide 16 adjustable along slide 15. In operation, slide 16 is adjusted along slide 15, and the master form 35 is adjusted to determine the angle of the tapered hole to be ground, which angle may be zero if a cylindrical hole is required. During reciprocation of the spindle, the master form 35 causes the rod to rotate the screw 30 in the nut 29 and axial reciprocate the pusher 13 which, in turn, radially reciprocates the carriage 15 and grinding tool 18. The master form is laterally moved by the drive to shaft 39 to cause feed of the tool. In another embodiment, the pusher (85, Fig. 7. not shown) is disposed eccentrically of the spindle.

[Class 78 (i)] A transfer device for interposition between two non-parallel conveyers effective to turn articles such as confections, without dropping them or changing their order, through less than 180‹ comprises a flexible belt 12, Fig. 1, made up in the form of a hollow cone. The belt may consist of paper, canvas, or the like, Fig. 8 of sector formation. The angle a will vary according to the angle between conveyers b, c, Fig. 1. Edges 11 are secured together to form a cone. The belt is supported on a plane surface 14 having two intersecting side edges 15 with a preferably rounded corner 16. The edges are not necessarily at right angles. The belt hangs down as in Fig. 2 being pressed as by the weight of an idler roller 17, and is driven by rolls 19 in such a way that a radial as well as a tangential pull is imparted thereto. An opening 20 in the surface 14 allows the lower roll 19 to engage the belt. The axis of the rolls are not parallel to the radial line l, hence the belt is stretched outwardly. The rolls are driven from a motor 28. The idler roller 17 is preferably conical and has trunnions 30, 31 at its ends. The front trunnion is mounted in a bearing 33 and held against undue axial movement by a collar 34. The bearing block 33 is pivoted to radius links 35. The rear trunnion 30 is slidable in guides 32. The idler is then free to follow the belt. The transfer device is mounted between the ends of conveyers b, c, the edges of which are adjacent edges 15 of the transfer device.
