Title: Improvements in patterning mechanism for knitting machines
Inventor: FARMER ERNEST LEONARD
IPC: D04B15/66
Filed: 1963-04-10
Abstract: 992, 531. Knitting-machines. WILDT MELLOR BROMLEY Ltd. April 10, 1964 [April 10, 1963], No. 14261/63. Heading D1L. A circular multi-feed knitting machine comprises a patterning mechanism which is controlled by a jacquard system. As shown in Fig. 4 jack selecting members 7 are pushed into their operative position (shown full lines) by the armatures 8a of electromagnets 8 against the action of springs 20. The jack selecting members are in a vertical stack and are pivoted about the rod 13, their limits of movement being restricted by the abutment of one or other of the sides of a hole 22 against a vertical pin 21. A vertical catch 14 is arranged to separate the selected and unselected members by being held between the projections 7a on the members and it is held in this position by the abutment of the arm 16 on the surface of the rotating needle cylinder. When the arm 16 reaches the depression 18b the catch 14 is released and the selecting members 7 return to their inoperated position under the action of the springs 20 and push back the armatures to their starting position ready for re-selection. A modification of thie selecting mechanism appears in Fig. 5 (not shown) in which a lever 27 which follows a cam track in the cylinder holds all the selecting members in their operative position prior to actuation of the electromagnets and as this lever moves it allows selected armatures to hold the selecting members in their operative positions whilst non selected ones are returned to inoperative positions by means of springs. A perforated jacquard tape 9 passes over a perforated drum 10 and fingers 36 on arms 34 of a bell crank lever (Fig. 8) cause operation of a microswitch 37 which passes information to the solenoids previously described. A cam 38 rotates to lift the fingers 36 clear of the holes to prevent accidental breakage when the drum 10 is moved. Switches 47 operated by a cam 49 in the drum 10 (Fig. 9) work in conjunction with the microswitches 33 to cause actuation of the solenoids. The bell lever 33 may be replaced by photo-cells operated by light bulbs held in the drum 10 to cause energization of the solenoids 8. Fig. 14 (not shown) shows a patterning unit which is applied to a stationary cylinder machine.

Abstract: 514,713. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., ROCHE, A. H., and GOULLEE, S. J. May 13, 1938, No. 14355. [Class 40 (v)] In a negative feedback amplifier in which a blocking condenser in one arm of the output bridge has appreciable impedance another condenser is inserted in an adjacent arm of the bridge to maintain the output impedance constant. The Figure shows an amplifier in which a condenser C10 is added to the output bridge R<13>, R<14>, R<15>, to compensate for the condenser C<9>. A decoupling resistance is provided so that variation in the impedance of the HT supply does not affect the balance of the output bridge. Gain control may be obtained by changing the feedback connection from CA to CB in which case a resistance R' equal to R3 is preferably included in the feedback circuit to maintain the correct termination. With reduced feedback the link HF is preferably opened for the condenser C<8> which corrects for rise in the output impedance at high frequencies. Attenuation due to condenser C<8> is compensated by the shunt R<8>C<4> in the feedback path. Condenser C<7> in addition to serving as a blocking condenser may also adjust the gain-frequency characteristic, and may be proportioned to give a slight rise in gain at the lower frequencies.

Filed: 1971-05-13
Abstract: 1336476 Control devices HOLZER PATENT AG 13 May 1971 [14 May 1970] 14631/7l Heading F4G A control device for a tumbler drier 4 comprises a moisture content detector 1 which detects when the moisture content of clothes &c. being dried has reached a chosen (high) value and then activates a clockwork time switch which after a predetermined time de-energizes the drier 4. Since the moisture content is measured while it is still high, e.g. 20%, the input resistance of the detector 1 may be low, e.g. 4-5 megohm. The detector 1 may sense the moisture content of the clothes by measurement of the electrical resistance presented by the clothes between electrodes 5 to modify the control input to the detector 1, or by discharge of a capacitor through the clothes. To energize the drier, a knob 10 is rotated by hand against the action of a spring 12 to a position corresponding to the desired final moisture content. This rotation of the knob 10 rotates a cam disc 16 (or discs or rollers) so that the switch arms 30, 30<SP>1</SP>, 31, 32, 33 enter slots 15 in the disc 16 or engage ridges thereon to close the contacts of the arms, so as to energize the heater 28, blower 27 and motor 29. When the moisture content reaches the chosen value, the detector energizes a solenoid 6 to release the oscillating escapement 36, 34, 24 so that the cam disc 16 is rotated by the spring 12 until after a predetermined time it first switches off the heater 28, switches on a warning lamp 26 or alarm bell 37 (which may be mechanically actuated) and switches off the blower 27 and the motor 29. The solenoid 6 may be arranged to release the escapement when it is do-energized.
