Title: Improvements in stop-motions for knitting machines
IPC: D04B35/10
Filed: 1924-11-11
Abstract: 242,437. Johnson, J. Y., (Crawford Manufacturing Co.). Nov. 11, 1924. Stop-motions ; bobbin stands. -Mounted on a standard 2 is a bracket 4 carrying radial arms 5 ior bobbins B and above them is a casing 6 containing the lower stop mechanism. Arms 7 radiating therefrom carry guides 8, consisting each of a fixed slotted plate 9, U-shaped in cross-section and a movable slotted plate 10 mounted on a rod 11. The thread from the bobbin below is passed into the plate 9 so as to retain the plate 10 in a vertical position. When this thread breaks the plate 10 falls and the rod 11, which extends into the casing 6, is rotated. A bent inner end 12 of the rod 11 then engages a disc 13, mounted within the casing on a central pivot capable of vertical adjustment, and moves it sufficiently to release a trip device, which can also be released bv the engagement of a bent end 47 of the trip lever with a pin 48 on a spindle 49 mounted in a bearing 52 on the casing 6. The pin may be set by means of a sliding block 53. The spindle 49 is connected by a rod 55 to a disc 59 in an upper casing 57. The disc 59 is mounted on a central spindle 60, with vertical adjustment, and is recessed at 67 to engage arms 68 on radiating rods 69, of which there is one to each bobbin B. The outer ends of the rods 69 carry hooks 71 over which the threads A from the lower guides 8 pass to a perforated ring 72. Arms 70 radiating from the casing 57 carry fingers 73 against which the hooks 71 rest, when raised. When a thread is subjected to excessive tension the hook over which it passes is drawn down and the corresponding rod 69 turns the disc 59 and acts on the trip mechanism in the lower casing. In order that light and heavy yarns may be used together, independent adjustment of the rods 69 is provided, consisting of screws 81 passing through nuts 79 pivoted to levers 76 connected by springs 75 to the arms 68. Specification 242,546 is referred to.

Patent GB-908054-A (GB)
Title: Needle knitting machine
IPC: D04B15/68
Filed: 1960-08-05
Abstract: 908,054. Knitting-machines. WILDMAN JACQUARD CO. Aug. 5, 1960 [Sept. 30, 1959], No. 27193/60. Class 74 (2). In a superposed aligned cylinder machine having independent needles selected by camactuated sliders and jacks, those jacks which have caused their needles to be transferred to the upper cylinder are prevented from following the path of the remaining jacks to a level at which, after serving at one feeding station, they may be selected for needle selection at the next feeding station, but are instead confined to a path by which they are, at the next station, raised to receiving position, so that in no circumstances may a needle be transferred from the upper to the lower cylinder without a slider being positioned to receive it. Between each two stations is a pattern strip P which is advanced each time in two steps, so that an end of any lever 27 may find either a hole 42, or a hole 43, or both. If an end of a lever finds only a hole 42, the other end is depressed by a cam 50 and the end 36 of a coacting lever 29 is caused to engage butt 24 of an associated jack 21 and raise its butt 20 above the point of a cam 58 so that that butt rides up cam 58 and the butt 14 of an associated slider 13 rises over a cam 74 to cause the needle to clear, take yarn and knit under cam 78, the jack being retracted by a cam 63 to pass under cam 60 and to be returned to original position by cam 66. If the lever finds a hole 43 only, its other end is depressed by a cam 51 which follows cam 50 and butt 20 rides up a cam 59, causing the corresponding slider butt to be raised and then to be lowered slightly by cam 77, so to cause the associated needle to tuck, the jack being returned, as before, by cam 66. If the lever finds a hole 43 after a hole 42, the end 36 of lever 29, in its second, upward swing, engages under butt 25 of the already raised jack and raises it further, so that butt 20 is above the point of a transfer cam 60 and rises up it to take the slider butt above the point of a transfer cam 75, with consequent transfer of its needle to the upper cylinder, the jack ending up above and out of range of action of cam 66. The slider is returned to inactive position by cams 77 and 78. The jack is lowered by cam 80 to permit of this, but is then raised by an extension 81 of cam 66 to a level at which it will be raised by cam 58 and raise its slider to cause it to ride up cam 74 to the path R which is a needle-receiving path. The pattern strip is stepped round by a Geneva mechanism.

[Also in Division G4] In an amplifier which has different gains for positive and negative signals, the gain is changed by means for imposing a change of polarity of input current by means independent of the signal. Amplifier 11 gives a phase reversed output and is provided with two negative feedback paths, i.e. (1) via diode 12 and resistor 14 and (2) via diode 13 and resistor 15, the diodes 12, 13 being so poled that for a positive input at terminal 24 diode 13 conducts and the gain is determined by resistor 15, whereas with a negative input diode 12 conducts and the gain is determined by resistor 14. An output is taken from the circuit via resistors 16, 17. A negative constant voltage source 21 is connected via resistor 20 and switch 19 to the amplifier input via resistor 22 and to its output via resistor 23. It is shown in the Specification that if certain conditions are fulfilled, with switch 19 open and a positive input, the output current is determined by the ratio of resistance 15 to resistance 17 while with the switch closed the output current is determined by the ratio of resistance 14 to resistance 16.
Patent GB-260630-A (GB)
IPC: G10K15/10
Filed: 1926-11-01
Abstract: 260,630. Kuchenmeister, H. J. Oct. 31, 1925. Sound grooves; simulating echo eftect in recording; tools for reproducing.-Sound records of disc or band form are made in such a way that when they are played on a machine having a single sound-box, the same effect is obtained as when an ordinary record is played on a machine of the kind having two or more sound-boxes tracking the same groove, one behind another. This artificial echo effect is produced, according to one method, by impressing a blank with the same matrix (obtained from the original recording) two or more times, each record impression beind displaced angularly with respect to the preceding one through an amount corresponding in playing to a time interval of say 1/30th to 1/8th of a second. A modification of the process consists in making from an original master record a matrix having thereon two phase-displaced records of the same sounds. In duplicating from this matrix, a single impression only is required. A further alternative consists in using two recording instruments simultaneously, at different distances from the source of sound: the matrixes obtained from these two original phase-displaced records are used to produce two directly superposed impressions on the same blank. The superposed sound traces may be of different kinds, such as hill-and-dale, or lateral cut. Soundreproduction from these may be effected by using a stylus adapted to operate with either tyre of groove, or by means of a single diaphragm connected with two closely adjacent styluses of the appropriate kinds. According to the Specification as open to inspection under Sect. 91 (3) (a), recording diaphragms of different kinds may be used in the process last described. This subject-matter does not appear in the Specification as accepted. Specification 259,946 is referred to in the Specification as accepted.
