Title: Improvements in progressive change-speed gears
IPC: F16H29/14
Filed: 1921-04-12
Abstract: 162,649. Henriod, C. E. April 28, 1920, [Convention date]. Variable - speed gearing comprises planet gears c carried by an engine flywheel a and controlled by oscillating members c<1> which are adapted to grip in one direction by electromagnetic means. The gears c mesh only with a central gear f on a shaft to be driven. The members c<1> are oscillated with variable amplitude by means such as levers d, Fig. 1 (Cancelled), controlled by a non-rotary eccentric c of adjustable eccentricity, the levers having toothed segments engaging segments c<11> on the members c<1>. Each member c<1> is encircled by a coil o, Fig. 3, which is excited for a portion of a revolution of the wheel a during which the member c' grips its companion gear c frictionally, and causes the gear f to be driven. For this purpose an arcuate fixed contact h is adapted to be engaged by brushes l carried by the members c'. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement with a mechanical reversible ratchet action. A semicircular holder h can be rocked in its socket so as to bring oppositely-acting gripping-rollers i, k alternatively into operation. Modified epicyclic trains are also described. Also the invention is set out as a patent of addition to No. 154,904. This subject-matter does not appear in the Specification as accepted.
Patent GB-399871-A (GB)
Title: Improvements in or relating to the manufacture of products containing rubber-bonded fibres which normally coagulate rubber latex
IPC: F16D69/02
Filed: 1932-04-15
Abstract: Latex, before being brought into contact with fibres which normally coagulate it, such as asbestos, is aggregated.  This aggregation connotes the collection of the particles into larger particles whose size may range from 50 to 200 microns, or even to 1/8 millimetre. The preaggregation may be carried out by the addition of definite amounts of hydrochloric acid, acetic acid, aluminium sulphate, sodium silicofluoride, zinc oxide, &c., or an artificial dispersion may be made by redispersing rubber to the size required.  Such preaggregated latices cream on standing, if necessary after dilution.  It is preferred to use the minimum amount of aggregating agent necessary. A protective agent such as h moglobin which also assists the dispersion of the asbestos, may also be added to the latex before or after aggregation, although this addition is unnecessary when the aggregating agent is a polyvalent metal salt.  The hydrogen ion concentration of the latex may be controlled by the choice of aggregating agent or by the addition of other agents and may result in an acid or alkaline-reacting latex.  The latex is preferably diluted to a 5-10 per cent rubber content before aggregation, and may be admixed with the asbestos slurry-preferably 5-10 per cent concentration-to give rubber corresponding from a few per cent up to 50 per cent of the weight of the asbestos.  The admixture is made while agitating, for example in a paper beater, and the material may then be sheeted or felted &c.  Fillers, including finely divided metals, pigments, and compounding agents may be added to the asbestos slurry before admixture of the latex or to the latex to cause preaggregation.  The product may be used for the production of asbestos paper, gasket material, fibre board, friction material, such as brake lining, brake blocks, electrical insulating panels, &c. Specification 223,263, [Class 70, Indiarubber &c.], is referred to.

Title: Internal framing for hollow panels
IPC: E04C2/36
Filed: 1945-05-01
Abstract: 597,413. Carpenters' joints. BALLOUX, L. May 1, 1945, No. 10979. Convention date, March 19, 1942. [Class 20(ii)] A cellular structure for the internal framing of a hollow panel comprises two series of crossed battens 1, 3. Each batten 3 has a series of cross-like openings 4 each having two diagonally opposite angles of the cross rounded as at 7. Each batten 1 has a series of opposite notches 2.

Patent GB-566224-A (GB)
Title: Improvements relating to machines for treating or dressing seeds or grain
IPC: A01C1/08
Filed: 1943-07-07
Abstract: 566,224. Treating seeds and grain. ROBINSON & SON, Ltd., T., and ORMEROD, H. July 7, 1943, No. 11052. [Class 58] [Also in Groups II and XXX] A machine for dressing seeds or grain to protect them from disease or insects comprises a pivotally mounted grain feed hopper a which, when the rate of the supply of grain to the machine falls below a predetermined minimum, tilts about its pivot e under the influence of a counterbalance weight and thereby stops the operation of the mechanism for feeding the dressing composition. In one construction, Fig. 1 (not shown), the hopper in tilting actuates a mercury switch controlling the motor which drives the feeding device for the dressing composition. In the construction shown, the hopper is connected to a centrally pivoted lever w, the bottom bifurcated end y of which embraces a lever z fulcrumed on a clutchoperating lever 2. When the hopper tilts under the influence of the weight j, the lever z is moved clockwise, Fig. 3, and a pivoted arm 4 carried by the lever is moved into the path of a lug 5 of a disc 7 which revolves with a sleeve 8 upon which a clutch part 9 is keyed. The abutment thus rotates the lever 2 in a clockwise direction and the lever thereby disengages the part 9 from the driving pulley 10. The drive for the feed for the dressing composition ceases until the hopper returns to its initial position, such movement bringing an arm 3 into the path of an abutment 6 on the pulley 10 and thereby returning the clutch to the position shown. A spring-controlled lever 12 serves to produce a snap action on the lever 2.

Title: Improvements in and relating to the grinding of curved surfaces
IPC: B24B17/00
Filed: 1933-04-18
Abstract: 417,612. Grinding curved surfaces. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Vasteras, Sweden. April 18, 1933, No. 11365. Convention date, April 22, 1932. [Class 60.] In the grinding of curved surfaces by the copying principle, in order to obtain an exact copy of the templet irrespective of scale, the desired curved surface is divided into a number of arc shaped elements, and the surface of the templet, which is engaged by a guide roller or other guide member, also is divided into the same number of arcs, of which the individual centres of curvature coincide with those of the corresponding elements of the work surface, and the grinding disc and the work and templet are so moved that the disc will at every moment touch the required surface at a point situated on the line joining the centre of the disc to the centre of curvature of the templet surface for the time being in action. In the example shown in Fig. 2, the surface to be ground is divided into arcs 3a, 3b, 3c, and the templet is divided into corresponding arcs 4a, 4b, 4c, the arcs having centres of curvature a, b, c respectively. The work and templet are rotated about the centre b, the grinding-disc rotates about centre O, and a guide roller 2 contacting with the surface 4a ... is provided. During the grinding of the arc 3b, the required conditions are fulfilled, but during the grinding of the arc 3a, the centre of curvature a moves off the line O, b by an amount x. In order to keep the point a on the line O, b, the templet is moved, during rotation through the arc 3a, by an amount x by the use of a cam 10 also rotating on the axis b and engaging a roller 11, the part 10a of the cam corresponding to the arc 3a of the work ; similarly the cam 10 has a part 10c corresponding to the arc 3c and giving a vertical movement to the work and templet of the amount y. A machine for carrying out the above process is shown in Fig. 3, and comprises a grinding-disc 1 rotated in fixed bearings 21 on a table 22 by an electric motor 20, and a holder 25 slidable in guides 24 on the table ; the table also supports a guide roller 2. The holder 25 has a vertical rack 26 reciprocated by a link 27 and crank disc 28 driven from an electric motor 30, and the rack engages a toothed arc 31 on a disc 5 connected to a shaft 32 carried by a slide movable in guides 36 in the holder 25. The disc carries the templet 4 and the cam 10 resting on a roller 11 carried by the holder 25, and the holder is pressed towards the grinder 1 and the roller 2 by a weight 37. In operation, as the disc 5 rotates it is moved by the templet 4 and by the cam 10. In a modification, the centre of the roller 2 may be above or below the line O, b, the arcs 4a &c. being turned through corresponding angles, and the surface of the templet then not being continuous; in further modifications, the roller 2 or the grinder may be moved instead of, or in addition to the movements of the work and templet. Specification 135,401, [Class 60], is referred to.
