Patent GB-483078-A (GB)
Title: Improvements in weft-feeler mechanisms for looms for weaving
IPC: D03D51/34
Filed: 1936-09-09
Abstract: 483,078. Weft-feeler arrangements. GLEDHILL, W. Sept. 9, 1936, No. 24551. [Class 142 (iii)] The devices are used mainly for drop box looms, but may, as described below, be modified for use with oneshuttle looms. Opposite each cell of the drop box, a spring - controlled feeler d with a horizontal arm d<1> is pivoted on the shuttle box, and when a cell is brought up or down to the level of the race way, a fixed cam i mounted on the lay acts to withdraw the feeler from contact with the active shuttle in that cell. When next the drop boxes move up or down, the cam i allows the withdrawn feeler to move inwards into contact with the previously active shuttle and if this is substantially exhausted the corresponding arm d<1> moves from a position behind to a position in front of a gapped plate m on a vertical spindle k. When the drop boxes now move to place the exhausted shuttle in active position, the cam i moves the arm d<1> back. During its movement the arm d<1> engages the plate m and turns the spindle k, which by lever mechanism moves a finger n<2> into position to engage a bowl and operate a lever. This actuates mechanism for stopping the loom replenishing the weft in the shuttle, or substituting a full shuttle for the exhausted one. Rods p mounted in front of each shuttle binder e are provided with fingers p<2> pressed by springs p<3> against the binders and with hooks p<2>. These normally prevent movement of the arms d<1>, but when a shuttle is boxed, the corresponding hook is swung clear. When only a single shuttle is used, the arm d<1> is acted upon by a cam r, Fig. 5, which is moved vertically by lever mechanism and a cam u<1>. The plate m which can swing vertically and rearwardly is moved vertically by a member v. The plate may be arranged to position a lever arm to engage a contact or abutment, so that on completion of the backward movement of the lay an electric circuit is closed, or a rod is rocked and the loom is stopped &c.

Title: Vertical deflection circuit
IPC: H03K4/72
Filed: 1976-06-14
Abstract: 1533447 Vertical sawtooth circuit MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 14 June 1976 [20 June 1975 (3) 24 June 1975 (2) 25 June 1975 (2)] 24612/76 Heading H3T A vertical deflection circuit comprising a sawtooth wave voltage generator 1 coupled at its output by a capacitor 2 to a drive stage 3 itself directly coupled to an output stage 5, 6 having a capacitor 9 and deflection coil 10 connected in series to its output terminal, and output stage bias voltage stabilizing circuit including a differential amplifier 19, 20 supplied with a constant current, as a power supply, from a constant current source 18 which operates only during the retrace, one input of the differential amplifier connected to a D.C. bias circuit 24, 25 and the second input connected to the output of a circuit 26, 27 producing a beam voltage of the signals appearing at the output terminal, and with the output of the differential amplifier connected to the junction b of the input coupling capacitor and the input terminal of the drive stage. As shown the mean value may be produced by an integrator 26, 27, Fig. 5 or by using the series combination of the deflection coil 10 and a capacitor 9, Fig. 11. Resistors 22, 23 are optional to improve the matching of the differential amplifier transistors 19, 20. Various modifications may be made to prevent picture bounce and temperature drift after turn-on, as by the connection of an impedance network 28, Fig. 11, which may include thermistors, and the use of the voltage across this to modify the amplitude of the sawtooth generated by charging a capacitor 31 and discharging it by an input pulse. To give a correct picture after re-turning-on shortly after switch-off, a diode (35, Fig. 10 not shown) may be connected to rapidly pull the voltage at the second input of the differential towards earth at switch-off. Alternatively, Fig. 11, the switching for the constant current source 18 is derived from the output and passes through a transistor 38 and two resistors 40, 41 so chosen that when the power supply at turn-off has fallen to 70% the pulse supplied is no longer enough to turn transistor 42 on and consequently the bias stabilization ceases to work. The transistor 18 may itself define the constant current or acting as a saturated transistor with a series resistance (45, Fig. 13 not shown) the current may be set by the resistance. When the power supply for the drive and output stages are raised during retrace (Fig. 14, not shown) in known fashion, the stabilization circuit may still be used.

Patent GB-224218-A (GB)
Title: Improvements relating to the dyeing of cellulose-acetate silk
IPC: D06P1/651
Filed: 1924-10-18
Abstract: The sulphurized compounds of phenol described in Specification 215,012 are employed in place of tannin for mordanting cellulose acetate silk.  With basic dyestuffs the tints obtained approximate to those produced on a tannin mordant and treatment with antimony salts is not necessary.  The mordant may also be added to ordinary dye baths containing substantive or sulphur dyes so that the dyeings produced therewith may be strengthened with basic dyes.  In an example, cellulose acetate silk is treated in a bath containing the mordant, caustic soda, and sodium phosphate, washed, and dyed with a basic dye.  The Specification as open to inspection under Sect. 91 (3) (a) describes the mordanting of "artificial silk" by the process and the use of sulphurized compounds of derivatives of phenol. This subject-matter does not appear in the Specification as accepted.

Title: Aerial anti-tank bomb
IPC: F42C15/22
Filed: 1953-09-08
Abstract: 732,952. Ammunition projectiles and projectile fuzes. SOC. ANON. BELGE DE MECANIQUE ET D'ARMEMENT. Sept. 8, 1953 [Sept. 15, 1952], No. 24860/53. Class 9(1). A fin-stabilised bomb containing a hollow charge and adapted to be dropped from aircraft is provided with a percussion fuze for initiation of a detonator to ignite the charge, the detonator being held away from the charge by locking means released by centrifugal force during fall of the bomb to allow the detonator to move to the armed position. Fig. 1 shows a bomb having a percussion fuze 1 mounted in a ballistic cap 2, which is secured in a thin-walled casing 3 housing a cast or compressed hollow charge 4 of hexogen or penthrite and a primary charge 5. A conical metal liner 6 for the hollow charge has an opening at its apex into which extends a tube 18 opening into a passage leading to a detonator 7. The detonator is housed in a carrier 8 which is screwed into a member 10 on to which the bomb-tail is screwed. The detonator is locked in the carrier by two semicylindrical inertia blocks 13, Fig. 3, bearing against a tubular element 14 extending into the carrier 8. The element 14 has a flared axial passage 15 and the arms of a flat spring 16 extend into grooves in the blocks 13 to hold them in position. Attached to the tail 9 are stabilising fins 19 which are connected at the rear by a ring 20. The fins are inclined to the axis of the bomb, so that as it falls it rotates and the resultant centrifugal force acting on the blocks 13 causes them to move outwards and thus release the detonator, which then moves forwards to arm the bomb. The blocks may also be held by spiral springs extending into recesses in the blocks, which are guided by slides projecting into grooves in the member 10. Fig. 6 shows a modification in which the detonator carrier 8c is provided with a boss 22 over which are hooked two arms 23, 24 mounted on a pivot 25 and connected at their outer ends, which carry inertia blocks 26, 27, by a spring 28. The tail tube is closed by a disc 29.
