Title: Manufacture of vat-dyestuff preparations
IPC: C09B67/28
Filed: 1926-03-31
Abstract: 250,251. Soc. of Chemical Industry in Basle. April 2, 1925, [Convention date]. Dye preparations.-Preparations of vat dyestuffs in solid form are prepared by intimately mixing the dyestuff with a non-caustic alkali such as alkali carbonate, borate or phosphate, and with a hydrosulphite, a dispersing-agent such as turkey red oil or sulphite cellulose lye being added if necessary. For example, the dyestuff paste is first mixed with the dispersing-agent, the non- caustic alkali is then added and the mixture evaporated to dryness; the hydrosulphite is incorporated after the product has been finely ground. The preparations dissolve easily in water, forming vats particularly suitable for wool dyeing. In examples, a preparation is made by grinding together in the moist state 2: 5-dianilido-1 : 4- benzoquinone, soda ash or its equivalent, and monopol soap solution, then evaporating the mixture to dryness, grinding, and mixing with sodium hydrosulphite; the brown dyestuff from sulphur chloride and 2: 5-dianilidobenzoquinone prepared as described in Specification 237,375 either alone or mixed with indigo, is incorporated with soda ash or potassium carbonate, monopol soap solution and sulphite cellulose lye, the mixture is then evaporated to dryness and ground, and finally mixed with sodium hydrosulphite; tetrabromindigo, soda ash, sodium hydrosulphite and sulphite cellulose lye are finely ground together; thioindigo, soda ash, and monopol soap solution are made into a paste, then dried and mixed with sodium hydrosulphite. Other dyestuffs or mixtures of dyestuff may be employed; thus there may be used dianilidoquinone and 2-thionaphthene-acenaphthene-indigo or a mixture of dianilidoquinone and indirubin. In the Specification as open to inspection under Sect. 91 (3) (a) the preparation from 2 : 5-dianilido-1 : 4-benzoquinone is made up with sulphite cellulose lye in addition to the monopol soap solution; in the preparations from the brown dyestuff described in Specification 237,375, the sulphite cellulose lye is omitted: and monopol soap solution is used in addition to sulphite cellulose lye in the preparation from tetrabromindigo. This subject-matter does not appear in the Specification as accepted.

Abstract: 765,290. Magnetic recording and reproducing devices. MOLLICA, S. March 28, 1955 [April 3, 1954], No. 9033/55. Class 40 (2). [Also in Group XVI]  In a device for magnetically recording and/or reproducing sound on a magnetic sound track of a motion-picture film 7, the film is arranged to pass, in the following order, means 15... 18, Fig. 1, for braking the film, a magnetic sound head 14, a shaft 5 and a freely rotatable roller 10 of yieldable material resiliently urged towards the shaft so as to contact both the film and the shaft, the latter carrying a flywheel 4, and an idle roller 21 resiliently urged in such a direction as to tension the film near the shaft. The braking means comprises a non-rotatable roller 15 against which the film is pressed by a rotatable roller 17 mounted on a lever 18 loaded by a torsion spring 16. The head 14, Fig. 6, has an air gap filled with a pure gold sheet 29 and the magnetic layer 28 of the film 7 is pressed against the head pole pieces by a magnetic resilient presser 27. The shaft 5 has a recessed portion 6, Fig. 5, of width and depth equal to the width and thickness of the film 7 and, the roller 10 being longer than the width of the recess 6, drive to the shaft 5 from the film is conveyed both directly and through the roller 10. The roller 21 is mounted one end of a lever 23 loaded by a torsion spring 22, and to the other end of the lever is anchored a spring 11 by which the roller 10 is urged towards the film, whereby downward displacement of roller 21 arising from increased film tension results in decreased pressure by the roller 10 on the film which may then slip on the shaft 5 and an accelerated portion issue from a reel 19. The lever 23 also carries a lever 25 having an idle roller 26 urged into film engagement by a tension spring 27 with a force less than that of roller 21. Rollers and a pin 13,12, 20 guide the film which is pulled from the reel 19 by a sprocket drum, not shown.

Title: New and improved arrangement for effecting adjustments of the inclination of the road wheels of a motor car
IPC: B60G21/00
Filed: 1954-03-29
Abstract: 751,646. Spring suspensions; preventing lateral canting; adjusting body height. DAIMLERBENZ AKT.-GES. March 29, 1954 [March 27, 1953], No. 9134/54. Class 108 (2). In an arrangement for effecting adjustments of the inclination of the road wheels and preferably also of the body of a motor car, for example, when travelling around a curve, adjusting means are adapted for being actuated or controlled at will by body movement of the driver relatively to the car. As shown in Fig. 1, front road wheels are supported by parallel linkages 1, 2 and 1<SP>1</SP>, 21 sprung by tension rod springs 3 and 4 respectively, the rear ends of the torsion rods being pivotally connected through lever arms 6 and 7 to opposite ends of a cylinder 10 arranged for sliding movement transversely of the vehicle. Torsion rods for rear wheel suspensions are also pivotally connected to the cylinder 10 through similar further lever arms. A piston 13 within the cylinder 10 is connected through rods 14 and 15 to a part 16 rigid with the vehicle body, and a slide valve 37 in a valve casing 21 within a housing 22 attached to the cylinder 10 is pivotally connected through rods 38, 39 to a driver's seat 40 which is pivotally mounted longitudinally of the vehicle. Passages 17, 18 in the lower part of the cylinder lead to ports 19, 20 communicating with the valve casing 21 which latter communicates through a port 23 with the pressure side of a gear pump 26. The lower side of the housing 22 communicates with the suction side of the pump which comprises gear-wheels 27, 28 and 29 and which is fed from a reservoir 36. In operation, inclination of the driver's seat by the driver towards the inside of the curve, when the vehicle rounds a curve, moves the valve 37 to the left and admits pressure oil to the left hand side of piston 13 to move cylinder 10, relative to the piston, to the left to vary the stressing of torsion rods 3 and 4, until the valve 37 and the ports 19, 20 again assume their normal relative positions shown in Fig. 1. Movement by the driver to a vertical position upon completion of the curve effects movement of the valve 37 and cylinder 10 in the opposite direction to again restore the parts to the position shown. In a modification, Fig. 3, the lever arms slidingly engage end faces of rams 51, 52 working in a ram cylinder 53 attached to the cylinder 10, the piston 13 in which is rigidly connected through rods 54, 55 to points on opposite sides of the vehicle. The cylinder 53 includes spaces 60, 61 for the respective rams which communicate with a pressure installation (not shown). In operation, pressure oil admitted to cylinder spaces 60, 61, in dependence upon vehicle loading, varies the stressing of the torsion rods 3, 4 equally, while stressing of the rods, in dependence upon the inclination of the driver's seat when rounding curves is effected by the relative movements of cylinder 10 and piston 13.

Title: Vehicle suspension
IPC: B60G21/04
Filed: 1967-02-27
Abstract: 1,145,346. Vehicle independent suspensions. FORD MOTOR CO. Ltd. 27 Feb.. 1967 [3 Nov., 1966], No. 9176/67. Heading B7D. A suspension for the front steerable wheels of a vehicle comprises for each wheel a hub carrier 16 carried by a leading arm 28, which from an outwards direction from the vehicle longitudinal axis is inclined downwardly and rearward ly on a steering pivot axis 20, which from an upwards direction is inclined inwardly and rearwardly of the vehicle. The arrangement permits the changes in steering movement on the wheel due to changes in the castor and camber angles of the wheel when it rises to balance one another. The arms 28 may be sprung by coil springs (Fig. 1, not shown), by torsion bars 36 mounted on the pivot axes of the arms 28 in a cross member 30 which is resiliently mounted in the spring mass to provide a limited anti-roll stabilizing effect, or by torsion bars (48) running parallel to the vehicle longitudinal axis (Fig. 5, not shown) or at an inclination to this axis (Fig. 6, not shown) with right angled ends connected to the leading arms. To reduce or prevent brake-dive it is arranged that the line 40 in a longitudinal vertical plane of the vehicle passing through the tyre contact point of each wheel should pass through the pivot axis 38 of the arm 28 and through a transverse projection of the centre of mass of the vehicle on the plane.

Title: Improvements in and relating to means for filtering liquids
IPC: B01D35/00
Filed: 1932-03-31
Abstract: 399,207. Filters. BRYCE, Ltd., Kelvin Works, Hackbridge, and SIDNEY, A. A., 36, Chipstead Avenue, Thornton Heath, both in Surrey. March 31, 1932, No. 9287. [Class 46.] A filtering device, particularly for filtering liquid fuel for internal-combustion engines, comprises two concentrically arranged cylindrical metal gauze filtering elements 2, 9 of fine mesh and a corrugated filtering element 1 of felt, fabric, leather, or like fibrous material disposed therebetween, the filtering elements being all clamped fluid-tightly between clamping discs 12, 13 and the assembly mounted vertically, or substantially so, within a tubular container ; it is stated that by using this arrangement all the disintegrated particles of the felt &c. carried away with the filtered liquid are prevented from passing out of the filtering device. The filtering elements 2, 9 may be supported on a number of metal ring members 7, 10 on tubular members 8, 11 respectively of perforated metal. The filtering element 1 may be formed by winding the felt &c. re-entrantly around two circular rows of vertically arranged rods 3, 4 secured to upper and lower disc members 6, 5. Felt washers 14, 15 may be interposed between the ends of the filtering elements and the clamping discs 12, 13 to ensure a fluid tight-joint. The filtering elements may be disposed in a cylindrical casing member 19 the ends of which bear on end cover plates 17, 21, and the whole clamped together by means of a tubular member 16, a clamping nut 22 and a pipe union 23 ; washers 20, 28 may be inserted between the member 19 and the plates 17, 21. The liquid to be filtered enters through the inlet 24 and is directed downwardly by a baffle 25, the liquid passes through the filtering elements 9, 1, 2 and through transverse holes 18 in the tubular member 16 and leaves through the outlet 23. The upper disc member 6 and the upper clamping disc 13 may be downwardly dished as shown ; any air or other gaseous matter liberated from the liquid during its passage through the filtering elements passes upwardly and, due to the downwardly dished form of the members 6, 13, passes outwardly to the rim of the upper clamping disc 13 and then passes between the outer rim and the upper end cover plate 21 into the space 29 formed between the disc 13 and the plate 21. The air &c. may be withdrawn periodically from the space 29 by removal of a vent plug 26. The lower end cover plate may be provided with a drain plug 27.

Abstract: 1,168,321. Inserting transparencies into frames. GEIMUPLAST PETER MUNDT K.G. 1 March, 1967 [4 March, 1966], No. 9636/67. Heading A4X. [Also in Division B8] In a method of inserting transparencies 1 of a film strip in two steps into frames 2 and severing a transparency from the strip between the two steps, the second step is taken in the severing station, i.e. without moving the frame and the partly inserted transparency to another station. The second step is carried out by a gripper 27 having a pair of rubber covered jaws 23, 24 which engage a transparency through the frame aperture and move it longitudinally. The jaws are adjusted to lie exactly in the plane of the frame so that transverse camber of the transparency does not prevent it from entering the frame. The film strip is fed in steps by a device, Fig. 4, comprising two pressure bars 11 which press the strip against a guide 13 and grippers 10 pivotally mounted on a reciprocating carriage and engaging the perforations of the film. When the film strip encounters an obstacle the grippers 10 were caused to pivot by the moving carriage and push the pressure bars 11 upwardly against the action of a tension spring 12. A switch 17 is then operated and the cycle is completed without a feeding movement of the film strip. A new cycle cannot be initiated until the obstacle is cleared. The pressure bars 11 are normally held by a bolt 31 in grooves 32 in guides 29. Immediately before entering the frame 2 the strip is moved through a deflecting device 3 Fig. 1 which eliminates any longitudinally extending transverse camber on the film and which comprises two vertically aligned guides 4, 5 which guide the strip at its edges only; the film strip moves out of the device in a plane below its entry plane.
