Title: Improvements in or relating to automatic baling mechanism
IPC: A01F15/08
Filed: 1946-08-17
Abstract: 615,876. Binding hay &c. JONES, D. T., and JONES, G. Aug. 17, 1946, No. 24550. [Class 6 (iii)] [Also in Group XVII] A baling mechanism of the travelling pick-up or stationary type, includes a slotted breast plate adjacent to which the tying mechanism is mounted, the said breast plate being provided with protection plates disposed transversely of the slots and so contoured and positioned as to obviate or minimise likelihood of obstruction of the tying mechanism by extrusion of the material being baled. As shown in Fig. 1 a baling machine comprises a frame 1 mounted on, a chassis at the forward end of which is an elevator having a rotary pick-up 3 provided with spring tines 3a. The elevator is preferably mounted at its upper end, its lower end when in use being supported on a pair of castor wheels 5. A hopper 7, open to the upper end of the elevator, feeds material to be baled to the baling mechanism by a three-pronged rake 9 actuated by a three-point linkage 10 with spur wheels 11 in mesh with pinions on a main. driving shaft 13. The material is forced into the baling chamber 8 by an upward swinging ram 14, preferably also actuated by connecting rods from the said threepoint linkage. The baling chamber may have an extension 8a bound by adjustable tie-rods 25 to enable the delivery of a highly-compressed bale. The baling mechanism may incorporate a power unit 27, which, together with the elevator and rotary pick-up, may be detachable. The baling chamber comprises a breast plate 18 as shown in Fig. 4, provided with knives 19 of the guillotine type, and with protector plates 18b so positioned as to mask or shield the portions of the slots 18a which diverge to guide twine to the tying mechanism. According to the Provisional Specification additional protection may be afforded by a narrow strip or plate inserted in the slots adjacent the protector plates and so contoured as to further guide the twine while preventing extrusion of material through the slots. In place of rakes 9, a " nags head " feeder may be used which receives material to be baled from a short horizontal conveyor or horizontal extension of the elevator.

Title: Improvements in trim corrector devices for vehicles with fluid suspension
IPC: F16K17/08
Filed: 1960-07-14
Abstract: 937,170 Controlling vehicle height. F.S. ALLINQUANT. July 14, 1960 [July 31, 1959], No. 24582/60. Class 108(2). A vehicle trim corrector device has manual means to put two unequal fluid flow paths connected to a suspension unit into action simultaneously, the action of the greater flow path being controlled by means dependant on the relative positions of suspended and non-suspended parts of the vehicle. Fig. 1 shows a rear suspension layout comprising two hydro-pneumatic suspension units 3, 3<SP>1</SP> each connected to an outer chamber 12, 12<SP>1</SP> of a box 9 by air lines 8, 8<SP>1</SP>. Box 9 has an inner chamber 11 forming a reservoir for high pressure air drawn in by electrically driven pump 13 from the two outer chambers and two electrically operated valves 15, 151 controlling return follow to the outer chambers. The valves will allow a greater return fluid flow than the pump output but are normally spring-closed. Electrical connections are provided as shown in Fig. 2 which includes an optional additional system for the front suspension. When manual switch 24 is closed pump 13 starts withdrawing air from the suspension units lowering the vehicle until microswitches 18, 18<SP>1</SP> close when the normal ride position is reached. These complete the circuit to the valves 15, 15<SP>1</SP> which open allowing air to enter the suspension units to raise the suspension until the micro-switches again open. Thus the vehicle height oscillates about a position determined by the microswitches. Warning lights 27, 271 on the dash panel 25 light when the valves are open and flash when the vehicle height oscillates to indicate to the driver that the switch should be released. In a modification a time switch may be used to release the switch 24. Operating push button switches 37, 37<SP>1</SP>, 38 opens the valves from the reservoir independantly of switch 24 to increase the height to its maximum for jacking the vehicle. In an alternative embodiment of the invention a pump may be used to inject fluid into the suspension units and valves used to control withdrawal of the fluid. Specification 841,464 is referred to.

Title: Apparatus and method for producing a nonwoven fabric
Inventor: KALWAITES F
IPC: D04H1/70
Filed: 1971-04-19
Abstract: 1353056 Non-woven fabric; re-arranging fibres in non-woven fabrics JOHNSON & JOHNSON 19 April 1971 [24 March 1970 (3)] 25171/71 Headings D1R and D2B A non-woven staple fibre web comprises areas of high and low fibre density formed by directing fluid through the web while it is lying on a supporting member comprising discontinuous impermeable portions surrounded by a continuous sieve-like permeable area. An apertured member may be located between the fluid directing means and the web. As shown, Fig. 1, fibre web 41 is fed between continuous running support belt 30 and an apertured member in the form of rotating drum 15, water being sprayed from nozzles 29 through the drum material and belt to rearrange the fibres. Suction boxes 43 extract water from the web. Belt 30 has, Fig. 4, a square pattern of discontinuous domed impermeable portions 51 surrounded by a sieve 50, and drum 15 has uniformly spaced apertures 19. The portions 51 may have any shape, and may be in any pattern. The apertures 19 are larger than the apertures in sieve 50, and preferably have a diameter of at least 95 microns. Each impermeable portion may have a ratio of largest to smallest dimension of not more than 4:1, e.g. not more than 1.5:1, a largest dimension of not more than one inch, and an area at least four times the area of an aperture in the apertured member. The smallest width of the sieve may be at least twice the width of, and at least twice the pitch of an aperture in the apertured member. Alternatively, Fig. 13, fibre web 143 is passed between wet-out rollers 136, 137 which preferably control the webs' moisture content to 150 to 200 p.b.w. The web is then carried on endless belt 144 beneath water jets 151 to rearrange the fibres. Belt 144 has the construction shown in Fig. 4. The sieve portion of belts 30 or 144 may be in the form of a woven wire or nylon screen, Fig. 5, having strands 85 weaving over and under straight strands 84. The kinks in strands 85 define between them troughs 87 each extending parallel to strands 84, and also troughs 88 each extending parallel to strands 85. The depth of each trough is preferably at least 28.5 microns, e.g. from 47.5 to 7.50 microns, and the distance between two adjacent kinks is preferably at least 142 microns, e.g. is at least 28.5 microns. A web, Fig. 9, produced by the apparatus of Figure 1 contains holes 101 produced by the water flowing on portions 51, and areas of low fibre density 103 produced by water flowing through apertures 19. The use of a sieve having troughs produces a web having holes lying within areas 103. The initial web may comprise one or more layers of natural, mineral or synthetic fibres which have been carded or air laid, or laid by liquid depositions. The redistribution of a web of viscose rayon fibres is exemplified. The preferred fibre length is from 0.25 to 2.5 inches.

Title: Improvements in or relating to gramophones, loud speakers, and the like acoustic instruments
IPC: H04R1/16
Filed: 1927-09-23
Abstract: 306,915. Linsell, A. A. Sept. 23, 1927. Electric pick-ups, supporting; diaphragms not associated with sound-conduits.-A gramophone, loud-speaker, or like acoustic instrument comprises a vibratory member and one or more substantially reflectionless lines (i.e. bodies of considerable length, which absorb acoustic vibrations) serving wholly or mainly to support the vibratory member and thus render it aperiodic. The invention is shown in Figs. 2, 3 and 5 as applied to various forms of electric gramophone pick-ups. The application to a gramophone reproducer of the large diaphragm type is also described. In the pick-up shown in plan in Fig. 2, a coil 6 is mounted on an arm which constitutes a reflectionless line, and is made wholly of rubber, or, as shown, comprises a part 3 of wood or the like and a section 5 of material such as rubber. The arm carries at its outer end a stylus 2, and its other end is mounted so that the arm can swing horizontally and also rock up and down. The coil 6, preferably rectangular in section, projects between the poles 7 of a magnet mounted on a fixed arm 8. The coil is long enough to allow for the traversing movement across the record, or alternatively the magnet may be so mounted that it can move across the record with the stylus, but without vibrating. The positions of the coil and magnet may be interchanged, and these parts may be replaced by a magnetic armature and wound magnet system. Fig. 3 shows a modification wherein a magnet coil 13 is mounted on an arm 3 carrying a reflectionless line 10, the outer end of which is provided with a stylus 2 and also supports a webbed bracket 11. This carries a magnetic armature 12, adjacent to the coil 13. For reproducing sound directly from a gramophone record, a large diaphragm of light and stiff material may be mounted on an arm such as that described above, the diaphragm being vibrated by a stylus attached preferably at the end of a line of symmetry. Instead of rubber, the material known under the registered Trade Mark "Celotex" may be used in the reflectionless lines. Specification 278,158 is referred to.

Filed: 1929-08-19
Abstract: 338,516. British United Shoe Machinery Co., Ltd., Ricks, F., and Woodcock, R. B. Aug. 19, 1929. Lasts.-Relates to lasts particularly intended for use in shoe making processes of the kind described in Specification 238,806, wherein an upper moulded to the shape, of the last at both ends, and fastened at those ends only to the insole, receives a last which forces the ends to the correct distance apart, and supports the upper for the completion of its shaping. The last comprises wooden fore and heel parts separated by a plane cut A approximately at 24‹ to the axis of the last peg hole c and sufficiently close to the heel end for the forepart to contain the last peg hole. To the forepart is riveted a plate B, which may be integral with the last peg socket, and is provided with a hook F for engagement with a pin G in the heel part, a step L for engagement with a spring plunger K in the heel part, and a sliding pin M for engagement with the plunger and normally projecting into the last peg hole. In use, the fore part may be supported on a peg too short to reach the end of the socket the heel part positioned in the shoe and this threaded over the fore part. As the heel portion is depressed the pin G engages the hook F and, simultaneously, the plunger K snaps behind the step L. To unlock the last, when the work is to be removed, the last may be placed on a last peg having a step at its end and rotated about the last peg axis, the pin M being thus depressed to push the plunger K clear of the step L. When laced work is being dealt with, a loose instep piece may be introduced after the major fore part and heel pieces have been positioned in the shoe. Specification 206,176 also is referred to.

Patent GB-481940-A (GB)
Title: Improvements in the sealing of electric lead-in wires into glass envelopes
IPC: H01K3/20
Filed: 1936-09-16
Abstract: 481,940. Sealing wires into vitreous material. ROBINSON, E. Y., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 16, 1936, No. 25264. [Class 36] In sealing three or more leading-in wires into glass envelopes, such as thermionic valves, the wires are held in the correct angular or circular spaced relationship by means such as a jig 7 so that they project into the open end of the glass bulb or tube 5 which is softened by the heat of gas flames 18, the glass then being pressed in between the leading-in wires to form inwardly directed tongues which meet and unite with one another to make a vacuum-tight seal and end closure for the bulb or tube 5. The means for holding the wires in the correct relationship may comprise part of the internal electrode structure, such as an insulating crossframe, whilst the tube into which the wires are sealed may constitute the bulb of the valve. In the example the apparatus comprises two coaxial shafts 1, 2 which are rotated at the same speed in the same direction. The shaft 1 is hollow and carries spring-clips 4 which engage the tube 5 and hold it in position. The tube 5 has a reduced extension 6 which fits into the bore 3 of the shaft 1, preferably with such good contact that air or a neutral gas may be blown from the left-hand end of the shaft 1 into the tube 5, or a rubber washer or gasket may be used to obtain a gas-tight union between the tube 5 and shaft 1. The shaft 2 carries the jig or wire-carrier 7 which, in the example has six holes parallel with the axis of the shaft. A collar 11 fixed upon the shaft 2 forms a mounting for pivots 10 for a series of bell-crank levers or fingers 9 which terminate in wedgelike jaws 8, the levers being actuated by links 13 connected to a slidable collar 15 on the shaft 2. The heating is preferably continued after the formation of the seal, to remove the strain from the glass, while the glass may be blown out slightly by carbon dioxide admitted through the tube 1, assisted by centrifugal action. The sealed leading-in wires may be of such thickness that their externally projecting portions may serve as contact pins, or supports therefor. A leading-in wire or a glass exhausting-tube may be sealed into the centre of the tube 5, collapse of the exhausting-tube being prevented by a reinforcing collar or liner such as a longitudinally split collar which may subsequently be removed. Specification 369,349, [Group XL], is referred to.
