Title: Improvements in and relating to Shuttle Guards for Sewing Machines.
Inventor: KERSHAW PERCY BERESFORD WRIGHT
IPC: D05B57/26
Filed: 1916-09-29
Abstract: 109,848. Kershaw, P. B. W. Sept. 29. 1916. Sewing-machines; lockstitchiny by shuttles.- Relates to a shuttle-guard which normally overlies the path of the shuttlecarrier and is adapted to be moved aside to allow withdrawal and insertion of a spool. The guard comprises an arm a secured to a segmental band b which is provided with projections g, h, i. These projections are held between a disk d and ring c secured together by bolts e and distance-washers f. The arm also has a spring catch k, which engages the usual shuttle-carrier retaining-member 5 to hold the arm in its retracted position. When the machine is restarted after inserting a fresh spool into the shuttle, the latter contacts with a pin l on the catch k and is forced into its operative position in its carrier and also releases the catch and, allows the spring n to pull the arm a over into the position shown in Fig. 3. The projections h, i act in conjunction with the washers f as stops to limit the extent of movement of the arm. The device is secured to the shuttle race by the bolt which secures the retaining member 5.

Title: Condition responsive circuits
Inventor: ATKINS CARL EDWARD
IPC: H03K17/96
Filed: 1965-04-01
Abstract: 1,099,854. Semi-conductor circuits. TUNGSOL ELECTRIC Inc. April 1, 1965, No. 13871/65. Heading H3T. [Also in Division G1] The approach of a person to an element 24 changes the capacitance between the element and earth, and this capacitance is applied in series with C60 across a capacitor 30, which together with a capacitor 62 is charged from a source 66 via a diode 70 and smoothing capacitor 74. The capacitors 30, 62 are both alternately charged and discharged through a neon tube 34 so that current pulses flow in resistors 32, 64 in opposite directions producing a differential voltage thereacross, which is a low null value in the absence of a person, R32 and R64 also C30 and C62 being equal in value. When a person is in the vicinity of element 24 the total capacity between earth and resistor 28 is changed. This increases the current flow through R32 during discharge of C30, C32 and the differential voltage becomes more positive and is fed to an amplifying circuit and a switching transistor 102. When transistor 102 conducts it short-circuits a normally energized relay coil 106 to give warning of the presence of a person. Amplifying circuit. The differential voltage pulses are fed to a first amplifying stage comprising transistor 80. The current amplified differential output therefrom is fed to a second amplifying stage comprising a transistor 88, through a capacitor 86. The emitter of 88 is earthed, while its collector is connected to the collector of transistor 80 through a resistor 90, a capacitor 94 and a resistor 92 being connected between the collector of 80 and earth for filtering and bias purposes respectively. For purpose of stability and bias a resistor 98 is connected between the base and collector of transistor 88. The output of the second stage is connected via a capacitor 100 to the base of a germanium PNPN switching device 102. Positive current from the A.C. source 66 is shunted past the device 102 by a diode 108. Whether negative A.C. actually will flow in device 102 depends upon the polarity of the base thereof which is dependent upon the combined output of a bias circuit (including a resistor 114, a resistor 116 and diode 118), which normally positive biases the base of device 102, and the amplified output negative pulses from the oscillator circuit via capacitor 100, which will be sufficient to drive the base negative in the presence of a person near detector 24. The device 102 therefore conducts and the relay coil 106 is de-energized, being shunted by diode 108 during positive half-cycles and by the device 102 during negative half-cycles.

Abstract: 474,530. Electric control systems. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. May 18, 1936, No. 13988. [Class 40 (i)] Electric consuming devices are controlled by H.F. carrier currents superimposed on the power lines, the carrier current being interrupted at a frequency corresponding to that of a relay at the receiving point, each relay having a mechanically tuned member adapted when energized to operate a switch. In the system shown in the Figure, a threephase transformer 1 supplying live wires 2, 3, 4 and having a neutral earthed wire 5, is associated with a transformer 8, 10, the primary 8 being supplied with H.F. current from a source 7 through a rotatable drum 9 with two rows of segments by which the H.F. current is interrupted at either of two rates. The secondary 10 is normally short-circuited by switch 17 which is only closed when the control system is operating. The interrupted H.F. carrier current is connected by a condenser 22 and rectifier 25 at the receiving end to give unidirectional impulses through relays 20, 21 operating one or the other of the tuned reeds 23, 24. These reeds, when vibrating, close a circuit through one or the other of the heating coils 26, 27 of a thermostatic relay so as either to open or to close a control switch for a street lamp 29 or other consumption apparatus. In a modification, a valve oscillator generates the H.F. current which is interrupted by either of two low frequency oscillators. The transformer 8, 10 is replaced by a choke disposed between the neutral earth line and the star point of the main transformer, the H.F. source being connected where required to the end of the choke which is not earthed. At the receiving end a single relay may energize either of the reeds.

Abstract: 383,627. Obtaining fibres. HAUGHEY, T. P., Stonewall Apartments, Danville, Virginia, U.S.A. May 15, 1931, No. 14461. Convention date, May 16, 1930. [Class 120 (i).] Fibres of flax, hemp, or the like are prepared for spinning by cutting partially decorticated fibres into lengths suitable for spinning, digesting the cut fibres in a weak chemical solution to dissolve the gum, and separating the fibres from the gum, the process preferably being carried out at a temperature less than 180‹ F. In an example, flax straw is decorticated, cut into the desired lengths, and tied into bundles which are kept straight on frames. The fibres are thoroughly washed in cold water and treated with a very dilute solution of potassium permanganate at 4-20 lbs. per sq. inch up to 40 mins. without heating. Alternative chemicals are other permanganates, caustic soda, saponifying or sulphonating oils such as castor, olive, linseed, soya or cottonseed oils, or distillates such as alcohol and glycerine, the strength of the solution being about # - ¢ per cent. Vacuum is then applied and air introduced at the bottom of the vessel, whereby violent agitation ensues and the gum and remaining shives rise to the surface. The gum may be recovered. This treatment causes the ends of the fibre bundles to taper and fray, whereby subsequent operations are facilitated. The fibres are washed, drained and squeezed and put into a mechanical beater, and, if necessary, neutralized with a very dilute acid solution, e.g. oxalic, sulphuric, phosphoric or acetic acid, and finally treated with a <1>/5 per cent solution of a silk softener. If further bleaching is required, chlorine water may be added to the water in the beater. The fibres are removed from the beater and passed to a mechanical picker, and dried with a warm air blast.
