Abstract: 1,143,691. Tuning arrangements. P. R. MALLORY & CO. Inc. 4 April, 1966 [12 May, 1965], No. 14779/66. Heading H3Q. [Also in Division H1] An arrangement for tuning over a predetermined band comprises a transmission line traversed by a contact on a rotatable arm which varies the effective length of the line by shortcircuiting it to another line or to the tuner housing, the line being terminated by inductance or capacitance or both. In Fig. 1, a U.H.F. tuner comprises a circular transmission line 14 mounted in a groove 13 on an insulated member 12 and fitting in a bore 11. Tuning is effected by turning knob 33, which rotates an arm 28 carrying a contact 27 consisting of a plurality of arms (47 in Fig. 2, not shown) engaging the line and a plurality of arms (46) engaging the wall of the bore 11. The end 16 of the line is bent inwards and forms an inductive stub with a corresponding flange 17. The value of the inductance is adjusted by moving a shorting piece 18 in a radial direction by means of a screw 19. The flange 17 is attached to a flat piece 38 which co-operates with three screws 21, 22 mounted in an insulating block 26 to form three variable capacitors. The centre capacitor 21 tunes the line while the other two are used as input and output couplings (Fig. 5, not shown). The screws 19 and 21 can be used for fine tuning after the knob 33 has been set for coarse tuning. In another form (Fig. 4, not shown) two concentric lines (48, 49) are used with the contact 27 moving between them. The line is shorted at one end (50) and terminated at the other by the capacitor 21, adjustment of which varies the distance between the ends of the concentric lines. Further adjustments are provided by the capacitors 22. Three such arrangements may be ganged together to tune the R.F. and oscillator stages of a superhet receiver, covering a range of 490 mc/s. to 1150 mc/s (Fig. 7, not shown).

Abstract: 1,143,887. Knitting machines. S. RAMSEIER. 24 Oct., 1967 [25 Oct., 1966], No. 48199/67. Heading D1C. An independent needle knitting machine has the needles selected by pivoting or failing to pivot jacks 1 coupled to the needles into one or other path in which their butts are caused to engage or miss cams raising them and their needles to an operative height. Alternatively, the needle butts themselves may be engaged to raise or lower the needles to an operative or inoperative height or the butts may be unaffected and the needles consequently uninfluenced in their position. As shown in Fig. 1, a notched wheel 11 is rotated in one or other direction by a step-by-step motor influenced by a programme, or is retained stationary whereby the ends of the pivoted jacks 1 are caused to be deflected into any one of three paths 16, 17, 9a and are retained in these paths by guides 18a, 18b. Prior to engaging the notched wheel 11 the jacks are guided by a camway 5 into a central position ready for selection. The jacks having been displaced, their butts can be operated by cams to cause the needles to make the necessary movements to knit, miss, or tuck. Alternatively, and as shown in Fig. 6, the jacks may be subdivided into two groups whereby their ends engage a pair of notched wheels 45, 46 arranged to deflect each group into separate guide channels. The notched wheel 11 may be mounted adjacent the needle cylinder of a circular machine as shown in Fig. 4 and engage the needle butts directly to raise or lower or maintain the needles unaffected whereby they are positioned for selection by further cams.

Abstract: 1290228 Automatic voltage control GENERAL ELECTRIC CO 11 March 1970 [17 March 1969] 11600/70 Heading G3R [Also in Division H2] In a conversion system using controlled rectifier at 13, the damping factor of the L C filter 14 on the DC side is improved by a first voltage regulating loop which compares a proportion of the unfiltered voltage Vu with a reference 16, the error being compared at 22 with a rate feedback voltage 21 derived from the filtered voltage Vo. A stabilizing network 20 (30, 32) Fig. 3 attenuates the ripple content of the proportional loop (which may include an isolating transformer) and prevents instability. The rate feedback may be derived from a transformer 37 the output of which is added to the proportional error voltage after operation by the lag stabilization network 30, 32. The rate feedback signal will override the error signal during transient variations in supply or load, thereby causing changes in Vu and stabilizing the filter 14 which may thus be anitically damped Fig. 2 (not shown) depicts the frequency response of the loops and filter. The invention outlaws inductance to be minimized in filter 14. The converter 13 may supply adjustable D. C. through a bank of variable frequency inverter supplying variable speed A.C. motors.

Abstract: 1301765 Coin - operated control devices WALTER KIDDE & CO Inc 21 June 1971  29022/71 Heading G4V A coin-operated selectively variable control device comprises a ratchet cam 36, Figs. 2 and 5, pivotably mounted on a shaft 34 and indexable by a stepping mechanism 66 responsive to electrical signals corresponding to the number of coins deposited in a coin receiver (not shown) and a switch-actuating cam 38, Figs. 2 and 6, selectively positionable on cam 36 and rotatable therewith so that cam surface 126 of cam 38 actuates a switch 120 via armature 122 after a predetermined number of coins have been received. In the embodiment described, which relates to a coin-operated car wash apparatus, each coin received generates a pulse in a coin pulsing device (12), Fig. 1 (not shown), which pulses cause reciprocation of the piston 70, Fig. 2, of a solenoid 72. Via a pin 78 in piston 70, the reciprocations are transmitted to arm 68, pivoted on shaft 34, and thence to a pawl 88 of stepping mechanism 66. Each reciprocation results in a rotation of ratchet cam 36 through one tooth 50, the movement being indexed by a detent 114 and spring arm 116. Teeth 50 of cam 36 are numbered, Fig. 5, apart from those beneath cam surface 52, and cam 38, Fig. 6, has an undercut portion 128, a spigot (162), Fig. 6A (not shown), depending from hole 156 of holes 130-156, and an arrow 158. In operation, cam 38 may be placed in any of the six positions such that spigot (162) engages one of the holes 54-64 in cam 36 and overlies the latter. The tooth number indicated by arrow 158 then designates the number of coins to be received before switch 120 is actuated and a car washing cycle begins under the control of a timer (16), Fig. 1 (not shown). Cam 38 may be replaced by other cams having greater or lesser undercuts 128, e.g. cam 164, Fig. 2, stored on a screw 168. To provide an auxiliary service, e.g. dispensing of liquid wax in the car wash apparatus, additional coins may be inserted, a second switch (170), Fig. 4 (not shown), being actuated by a cam surface (176), Fig. 7 (not shown), of a further switch actuating cam (40) selectively positionable relative to cam 38. The proper orientation of the cams at the beginning of a cycle is ensured by a homing device (198), Fig. 3 (not shown), which comprises an arm (200) coupled to piston 70 of solenoid 72 and arranged when reciprocated thereby to open and close switch (208). The arrangement is such that after the washing operation, timer (16), Fig. 1 (not shown), causes a reciprocation of piston 70 and thereafter further reciprocations by means of the homing device (198) until the cams are in their home position and switch 120 is opened. A circuit diagram, Fig. 8 (not shown), is given.
