Title: Improvements relating to the production of pattern effects on fabrics
IPC: D06Q1/02
Filed: 1923-02-22
Abstract: Fabrics composed of acetyl cellulose silk, viscose silk, or other artificial silk alone or in combination with other fibres which are not deleteriously affected by mercerizing-agents, are treated with a mercerizing-agent other than caustic soda in selected areas only. The treatment causes the fabric to resemble brocade and, in some cases, the fabric exhibits peculiar coloured pattern effects after dyeing, by reason of the treated portions having dyeing properties modified by the treatment.  The mercerizing-agent may be printed on the fabric, or the fabric may be printed with a resist such as starch paste, gum solution &c., and then immersed in the mercerizing-solution.  Suitable mercerizing-agents are sulphuric acid of 80 DEG -168 DEG  Tw; phosphoric acid of 129 DEG -160 DEG  Tw; hydrochloric acid of 26 DEG -40 DEG  Tw; nitric acid of 60 DEG -84 DEG  Tw; zinc chloride of 130 DEG -210 DEG  Tw; cuprammonium solutions containing 25-90 grams calcium thiocyanate per 100 c.c. Solutions containing mixtures of thiocyanates with or without neutral salts such as calcium chloride may be used. Examples of treatment using the several mercerizing-agents are given in the Specification.

Title: Improvements in Carburettors for Internal Combustion Engines.
Inventor: READ THOMAS JAMES
IPC: F02M23/03
Filed: 1918-03-28
Abstract: 124,579. Read, T. J., and Read, W. J, March 28, 1918. Closure members.-The casing c of a spray carburretor is open at both ends and has, fitting within it, a rotatable tubular valve i<5> having a series of orifices f<3> of gradually increasing size. One, or a portion of two of these orifices, is adapted to register with a fuel orifice in the casing wall fed from a float chamber a. Rotation of the valve therefore controls the fuel supply, and, to effect a simultaneous control of the air, the valve is adapted to actuate a pair of sliding shutters o which vary the inlet at the lower end of the tubular valve. The shutters slide in a guide o' which is secured by a circular flange o<6> to the casing c. Over the flange o<6> is fitted a pulley b, the rim b<4> of which is secured by screws t' to a flanged dust cover p<5> having air inlet ports p<3>. The cover is secured by screws t<2> to a disk i<18> on a spindle i<17> which is secured to a boss i<16> formed in one with webs i<15> from the valve i'. The pulley is recessed at b<17> for a portion of its circumference to receive a helical spring which returns the pulley after it has been displaced. To the inside of the pulley rim is secured a flanged disk b<5> eccentric slots b, in which engage pins o<11> on the shutter, the inner edges of which are cut away to clear the spindle i". The holes in the cover p<5> through the screws t<2> pass are elongated so that the pulley b and the shutters can be adjusted without moving the valve i<5>, thus permitting of varying the proportion of air to fuel. The pulley b is actuated by a Bowden wire in the groove b<3>. In a modification, the tube c is surrounded by the float chamber, and the aperture therein is controlled by a helical upper edge of the rotatable valve. The tubular casing is secured to the induction pipe by a union, bearing, through a spring washer, upon the top of the. float chamber. In a further modification the air shutters are dispensed with, the tubular casing and the rotary valve being ported, the maximum area of the ports being adjusted by a sleeve outside the casing and connected to the dust cover. Further, the fuel aperture is regulated by a tapered slot formed by mounting, adjustably, a piece of tubing at the upper end of the rotatable valve.

Title: Improvements in poultry-plucking appliances
IPC: A22C21/02
Filed: 1932-02-24
Abstract: 402,408. Plucking poultry. PESSELL, R. C., 28, Devon Square, Newton Abbot, Devon. Feb. 24, 1932, No. 5456. [Class 28 (ii).] In a machine for plucking poultry, gripping members are mounted on a rotary carrier and are withdrawn radially or substantially radially from the plucking opening in the casing, immediately after the closing of the grippers on the feathers, to effect a more positive plucking action. As shown, the grippers A are carried on members C pivoted at F to the rotary carrier E, and opposed gripper sets A are joined by a reciprocating rod B. Any number of rods B with grippers at the ends may be used, the grippers in one set being staggered with respect to the grippers on the adjacent sets. The grippers comprise fixed and sliding jaws, the latter being closed by a face cam on the side of the casing P and opened by a spring or springs ; or the closing may be effected by spring means and the opening by a cam. Immediately the grippers close to grip the feathers projecting through the plucking opening, the member C hits a stop O which withdraws the grippers away from the opening, the grippers at the other end of the rod B being moved away from the rotattional centre and opened for the discharge of the feathers. In a modification, the rods B are replaced by radially sliding rods, the inner ends of which engage cams on the casing, the withdrawal of the grippers, which are rigidly attached to the rods, being effected by spring means which operate at steps in the cam. The grippers in the modification comprise fixed and pivoted jaws, each pair having its closing spring, the opening being effected by a cam-actuated rod engaging extensions of the pivoted jaws. One or more plucking-openings may be provided, and an induced draught may be utilized for drawing the feathers towards the grippers and discharging the plucked feathers. A number of gripper carriers may be mounted on an extended shaft to enable several operators to work on one machine, and grids or combs may be placed at the plucking openings to prevent the skin of the bird from being damaged. A slower and more careful movement for plucking stubs may be imparted to an independent rotary member, of strong construction, by reduction gearing. Springs in the gripper opening and closing mechanism may be entirely replaced by cams or guides. According to the Provisional Specification an up-anddown and/or side to side feather-loosening action may be superimposed on the rapid backward jerk away from the bird.

Title: Improved switch control
IPC: B60L15/00
Filed: 1965-02-09
Abstract: 1,056,082. Electric selective signalling. BROWN, BOVERI & CO. Ltd. Feb. 9, 1965 [Feb. 11, 1964], No. 5549/65. Heading G4H. A switch mechanism of an electricallypowered vehicle is moved until a voltage corresponding to its position is equal to a second voltage derived from a coded value which represents the desired position and is derived from a plurality of two-state switching devices. The switching devices may be cams, or contactless switches in which a rotatable member can alter the coupling between two inductances and thereby the degree of damping of oscillations in a circuit. The switching devices provide the desired position in a progressive (i.e. monophylic) code which is converted to pure binary using exclusive-or logic (Fig. 3, not shown) and then used to produce a D.C. voltage (said second voltage) using weighted resistors. A similar arrangement may be used to produce the voltage representing the actual position.

Abstract: 972,189. Measuring electrically. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Feb. 15, 1961, No. 5662/61. Heading G1N. A force to be measured rocks beam 1 about a flexure pivot 6 and the movement is sensed by a differential transformer 9 the output from which is amplified and fed to coil 8, which is attached to the beam and moves in the field of permanent magnet 7, to tend to rebalance the beam, the magnitude of the current through coil 8 being then proportional to the applied force. Alternatively a displacement may be applied to one end of spring 5 the other end of which is fixed to beam 1 to convert the displacement to a force which is measured as described above. The beam displacement sensing may alternatively be capacitive having a differential capacitor connected in a bridge circuit the unbalance voltage of which is used to energize the rebalancing means and the indicator. The force on the beam due to the spring pivot is said to be cancelled by the attraction between the component parts of the position sensing device.

Abstract: 951,386. Rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 18, 1963 [Feb. 15, 1962], No. 5895/62. Heading H2F. A bridge rectifying circuit includes two additional rectifying elements 5A, SB connected as additional arms to the bridge and fed from the star point of the transformer winding or, in the single phase case, from its mid-point. The additional elements may comprise series or parallel arrangements. The effect of the additional elements is to permit the bridge to start even if the control circuits for the main elements provide only one pulse per valve per cycle. Also a smaller output inductance suffices to maintain the current, and the firing angle-output voltage characteristic is made more linear (Figs 2-5, not shown).
