Title: Improvements in or relating to the treatment of clays
IPC: C04B33/13
Filed: 1936-03-17
Abstract: Clay is precipitated from aqueous suspension by a flocculating reagent which comprises casein in the sol condition.  An acid or salt of flocculating properties such as sulphuric or hydrochloric acid or alum must also be present unless the clay possesses an acid reaction. In operating the process, the casein sol and the acid &c. are preferably added separately to the clay suspension, but they may be first mixed together if desired, preferably with the addition of a protector such as a small quantity of a gelatin or glue sol. Examples of operation are given and Specification 433,416 is referred to.

Title: An improved suspension for bogies with coupled axles
IPC: B61F5/36
Filed: 1934-03-14
Abstract: 420,641. Railway-vehicle undercarriages. MICHELIN & CIE, Clermont-Ferrand, Puyde-Dome, France. March 14, 1934, No. 8101. Convention date, April 13, 1933. [Class 103 (vi)] In a bogie for a railway &c. vehicle of the kind comprising two extreme pilot or guiding axles associated with one or two intermediate main axles, the suspension means of the main and pilot axles are linked by a load-distributing system of rods and levers so designed that substantially no variation occurs in the load on the pilot axles. In the four-axle bogie shown in Fig. 1, each of the pilot axles 2, 4 is connected by a non-elastic pivotal joint or by an equalizing spring to one arm 6b of a bell-crank lever 6 pivoted to the frame A, the other arm 6<c> being linked by a rod 7 to the arm 9<c> of a second bell-crank lever 9, of which the second arm 9<b> is connected by a rigid jointing to one of the main axles 1, 3. In addition, the two bell-crank levers are preferably interconnected by means of further rods 17 and a pivoted lever 12 so as to undergo equal displacements. The suspension springs B of the main axles are also associated through the medium of a lever C. The lengths of the arms of the bell-crank levers are so chosen that the load on the axles 2, 4 remains substantially constant, and the invention is particularly applicable to railway vehicles fitted with pneumatic tyres, in which case the usual guiding flanges attached to the wheels may be omitted from the intermediate wheels. Further constructions of four-axle bogies are described in which the leaf springs B are replaced by helical springs or a series of rubber washers, and in which the two intermediate axles are sprung on each side by the same leaf spring. In another modification, Fig. 4, a single intermediate axle 1 is employed, the rods 7 in this case being connected to bell-crank levers 9 jointed at their inner ends to a lever 11 pivoted at 13 to member 30 solid with the axle 1. A suitable connection between a lever 6 and a pilot axle 2 is shown in Fig. 7, in which a support 20 is ball-jointed at its ends to the lever 6 and to a spring-pressed element 21 slidable in relation to the axle 2.

Title: Method of producing hardboard in predetermined shapes and to a mat used in such methods
IPC: B27N3/18
Filed: 1961-03-06
Abstract: 913,395. Shaping hardboard. ABITIBI POWER & PAPER CO. Ltd. March 6, 1961 [March 21, 1960], No. 8105/61. Class 96. Shaped hardboard sheets are manufactured by die-forming with heat and pressure mats of bonded wood fibres which have been rendered flexible and capable of elongation by crushing, and, if desired, bending. The entire mat or selected areas only may be compressed, e.g. in a press or by pounding, or pressure may be applied successively to areas of the surface of the mat extending in one direction, e.g. by passing it between .crushing rolls. Crushable mats may be prepared by conventional wet lap methods, e.g. using a Fourdrinier machine, and, at any convenient stage, the mat may be impregnated (over selected areas only if desired) with 1 to 25% of one or more oils, e.g. drying oils of vegetable, animal or petroleum origin, or binding agents, e.g. asphalt, pine wood resin, polyvinyl acetate, phenol-formaldehyde resin, styrene-butadiene. The dried, stiff, board, having a moisture content less than 10%, preferably between 0.1 and 2.0%, of ¢-inch thickness, and density between 12 and 40 Ibs. per cu. ft. is crushed between rolls 13, 14, e.g. of 6-inch diameter, at a nip pressure of 10 to 15 lbs./sq. inch and then bent under an offset roll 19, rolls 10, 11, 15a and 16a supporting the mat. The operation may be restricted to selected areas and crushing and/or bending, in variable sequence, applied separately or simultaneously in one or more directions, preferably transverse to one another, to provide clearage planes 23a extending primarily parallel to the surface of the mat, which may, if desired, carry overlays of paper, cloth or plastic.

Title: Improvements in photographic recording
IPC: G03C5/17
Filed: 1947-03-25
Abstract: 650,455. Infra-red photography. URBACH, F. March 25, 1947, No. 8157. Convention date, March 26, 1946. [Class 98 (ii)] [Also in Group XL (a)] A method of infra-red photography comprises exciting uniformly with short wavelength radiation a layer' of a phosphor which stores the excitation energy and releases it trigger fashion when stimulated with infrared light between 0.8 Á and 2.0 Á as light of wavelengths intermediate the exciting and stimulating wavelengths, placing the uniformly excited phosphor in printing relation to a photographic layer sensitive to said intermediate wavelengths, stimulating imagewise the phosphor with the infra-red light and processing the photographic layer to yield a visible record. Numerous examples of suitable phosphors are given in the Specification. As shown, the phosphor 10 on a transparent support 11 is excited uniformly by ultra-violet light and after the spontaneous emission has ceased is stimulated image-wise by projecting on to it by means of a lens 22 the image of an object 21 illuminated by infra-red light from lamps 20, the infra-red light causing the phosphor to emit visible or near ultra-violet light which is recorded on an orthochromatic emulsion by projection through the support 11 or directly from the phosphor. In the latter case the emitted light may be focused by the lens 22 after reflection by a dichroic mirror 30 transmitting infra-red either directly or with an additional lens 33 on to an emulsion at 31, or reflected by a similar mirror arranged instead at 35 to a camera, or directly recorded by a camera arranged with its axis at a small angle to that of the infra-red system. Alternatively the infra-red image may be formed on the phosphor after passing through the support 11 and the light emitted recorded on a photographic material with its emulsion in contact with the phosphor. Such a method may be employed for obtaining infra-red spectrograms. The phosphor may be in the form of an endless band 74 moved intermittently past an ultra-violet source 75 and an infra-red image of an object 21 projected on to it at 72 by way of a dichroic mirror 70 and a lens 71, the infra-red and ultra-violet being prevented from reaching the same part of the phosphor simultaneously by a shield 77. The light emitted by the phosphor is transmitted by the mirror 70 and recorded at 81 in a camera. This arrangement may be employed when phosphors are used which operate at low temperatures, e.g. of liquid air, when the whole chamber 76 is brought to the required temperature. Specifications 650,458 and 650,459, [both in Group XL (a)], are referred to.
Patent GB-498788-A (GB)
Title: Improvements in wringers
IPC: D06F45/18
Filed: 1938-03-17
Abstract: 498,788. Wringers ; machinery safety devices. LOVELL MANUFACTURING CO. March 17, 1938, No. 8231. Convention date, July 6, 1937. [Class 138 (ii)] [Also in Group XXIV] The swinging of a wringer about a vertical axis in either direction is arranged to reverse the drive to the rollers, this being of particular use when an operator's hand becomes trapped, the natural action of the operator attempting to withdraw the hand causing the swinging movement. The wringer is secured to a casing 51 which is rotatable about a head 15 containing the usual forward and reverse drives 20, 21, 22. The head may be locked in any desired angular position about the tube 14 containing the vertical drive shaft 19 in known manner. A gear quadrant 43 is pivoted on the head and engages a pinion 42 on a shaft 40 which operates the clutch member 30 and the quadrant is provided with a slot 45 engaged by a pin 46 secured to the casing 51. The wringer, clutch and quadrant are shown in neutral position. The drive is transmitted by swinging the wringer either backward or forward according to the direction of roller rotation desired, the pin 46 rocking the quadrant and shifting the clutch to engage one or other of the bevels 20, 21. On an emergency arising, the wringer is pulled in the reverse direction to that in which it has been swung initially, thus moving the clutch through neutral and into engagement with the other bevel. A spring-pressed ball 62 normally retains the wringer in its forward, neutral, or reverse position.

Title: A weft stop motion device for looms
IPC: D03D51/34
Filed: 1955-03-22
Abstract: 765,049. Centre weft fork stop-motion for looms. VYZKUMNY USTAV TVARECICH STROJU A TECHNOLOGIE TVARENI. March 22, 1955 [May 7, 1954; Dec. 24, 1954], No. 8359/55. Class 142 (2). A weft fork is swung between the warp threads in synchronism with the picking and a weft thread is laid behind the fork and deflects the fork when it is withdrawn from the ‹ fabric. If the weft fails, the fork is not deflected and trip mechanism stops the loom. In one embodiment, a fork 7 is pivoted on a bolt 6 carried by a lever 4 which swings about a pin 3 to carry the fork between the warp 2. When the weft fails, the fork is not deflected on withdrawal and a tongue 16 engages a lever 18 whereby a cam 20 is turned and closes contacts 23 and a solenoid 26 is energized and the loom is stopped. In a second embodiment, the contacts, engage flats on opposite sides of the pin 6 and are normally closed. The weft deflects the fork as it is withdrawn and the bolt turns and opens the contacts. On weft failure, the contacts remain closed and further contacts in the circuit to the solenoid are closed by a cam, which overlaps the closing of the contacts 23, and the loom is stopped.

Title: System for the automatic operation of the controllers of electric traction outfits
IPC: B60L15/00
Filed: 1929-03-16
Abstract: 329,433. Della Riccia, A. March 16, 1929. Controllers, actuating; controlling motors by varying terminal voltage. -The controller is automatically operated, one notch at a time, by a reversible electromagnetic ratchet-andpawl arranged to receive current through a polarized relay responsive to the difference between two voltages, one depending on the actual speed of the vehicle and the other depending on the calculated mean speed corresponding to the actual notch at which the controller is standing. In the arrangement shown in Fig. 3<a>, a small generator E, driven by the vehicle is connected to oppose its voltage to that of a stepped potentiometer R2 which gives a voltage depending on the position of a contact K moving in correspondence with the notches of the controller (not shown). The resultant voltage energizes a polarized relay W to close contacts a or r when the difference reaches a given positive or negative value, and thus directs current from the same or another source to a torque-motor F which operates the ratchet. The effect is that the controller is notched up or notched back according as the actual speed is less than or greater than the calculated mean speed at the particular notch, during starting, accelerating, or braking; In a modified arrangement, the stepped voltages are derived from a small motor-generator having its field varied in steps corresponding to the controller notches. The ratchet-and-pawl mechanism may take the form shown in Fig. 5a, where a pivoted lever L, operated by the torque-motor of Fig. 3a, has a lost-motion connection to a lever M carrying the pawl A, and is also joined to the pawl by a link T; the effect being that a downward swing of the lever L brings the pawl on the ratchet teeth before the lost motion is taken up, and that the continued movement then moves the lever M and the pawl with it through one tooth. A selfinterrupter S ensures a sharp return of the mechanism.
