The racks 387 are pivoted to links 389, in turn pivoted to levers 392 carrying cam followers 394. Each follower 394 can be moved axially by pattern mechanism to engage either a circular disc 398 or one of the three cams 399, 401, 402. Each of the cams 401, 402 moves the welt hooks to a position between. the needles, the cam 402 maintaining the hooks in this position for a longer period than the cam 40] to facilitate the return of the welt loops to the needles. The cam 399 moves the welt hooks to an intermediate position in front of the needles, and to maintain the hooks in this position when the fabric is drawn off by the welt wire, means are provided for locking the lever 392 in the position to which it is raised by the cam 398. The lever 392 is released from the locking means when it is raised further by the cam 402. The group of five cams 285 is provided for actuating each set of knock-over bits 73 so that their movements may be different when yarn is being laid for the first course of the welt or during idling courses, when the first, say, eighteen courses of the welt are being knitted, when the following welt courses are being knitted, during the knitting of the last course of the welt, and subsequently when knitting with a reinforcing thread. The cams 285 act upon a follower 293 carried upon a lever 290 which acts through links 291, 287, 279 and lever 288 to operate the knock-over bits. For moving the follower 293 axially of the cam-shaft 42 to bring it into register with the various cams 285, a forked lever 295 is mounted upon an axially movable rod 296 controlled by patterning mechanism. The patterning mechanism comprises a disc 326 mounted upon a shaft 317 rotated intermittently by pawl-and-ratchet mechanism under control of a timing chain, the disc having pins 327 .. 331 of different length fixed in holes 332 therein. Some of the pins are of uniform diameter throughout their length, and others have the free ends reduced in diameter.

Patent GB-473167-A (GB)
Title: Method of and system for determining positions by means of a rotating radio beacon
IPC: G01S1/44
Filed: 1936-12-12
Abstract: 473,167. Directive wireless signalling. LORENZ AKT.-GES., C. Dec. 12, 1936, Nos. 34159 and 34160. Convention dates, Dec. 12, 1935 and May 19, 1936. Addition to 447,707. [Class 40 (v)] Relates to circuits of the type described in the parent Specification for counting the number of signals of two different kinds received from a rotating radio beacon. The signals applied to the counting circuit each consist of a positive and negative impulse, the sign of the first impulse of the pair determining which kind of signal is being received, and are applied in push-pull from a transformer T2 to a pair of discharge tubes Rl, R2. The first impulse of the pair triggers one or other of the tubes R1, R2 to discharge the condenser C in the common anode circuit through a counter Z1 or Z2, the second impulse being ineffective owing to the resulting lack of anode voltage on the other tube. As the beacon rotates the signals wane and wax in amplitude, and in accordance with the present invention in order to reduce the liability of the counters being operated by interfering impulses, the grid bias of the tubes R1, R2, is made dependent upon the signal amplitude by an A.V.C. system comprising one of the diodes of a double diode valve D, which rectifies signals supplied from a winding S on the transformer T2 to charge a condenser C4 in the said grid circuit. The condenser C4 is shunted by a rectifier K which prevents the grids of tubes R1, R2 from becoming positive. The other diode of the valve D is used to provide A.V.C. potentials for the high frequency amplifier H. In order to minimize the false operation of the counters Z1, Z2 by interfering impulses during the half-revolution of the transmitter when there would normally be no signals and the tubes R1, R2 would be at their maximum sensitivity, signals are emitted, during this period, of such a form that the differential indicator operated by the counters Z1, Z2 swings about its zero position.

Title: Circular Knitting Machines
Inventor: CARROTTE FREDERICK HENRY
IPC: D04B15/74
Filed: 1966-07-29
Abstract: 1,189,133. Knitting-machines. A. KIRKLAND & CO. Ltd. 28 July, 1967 [29 July, 1966], No. 34174/66. Heading D1C. In a circular machine having at least one pattern wheel or drum the peripheral speed of the wheel equals the average resultant speed of the needle jacks during the period in which they are moved radially of the cylinder by the wheel bits. The arrangement minimizes relative movement between bits and jacks. In a conventional wheel the jack butt pitch equals the wheel bit pitch therefore the number of butts on the arc Y of their maximum excursion in the vicinity of the wheel 11 is not equal to the number of bits in the arc X. Thus relative movement occurs between butts and bits. To avoid this relative movement it is arranged that the numbers of butts on arc Y and the bits on arc X are equal. This entails increasing the bit pitch, i.e. making the wheel bigger than would otherwise be the case, with a consequent increase in peripheral speed.

Title: Improvements in or relating to processes for treatment of abietyl compounds and the products thereof
Filed: 1935-12-10
Abstract: Abietyl compounds are isomerized by bringing them into contact, preferably at an elevated temperature, with an hydrogenation catalyst.  Abietyl compounds mentioned are abietic acid and its esters, e.g. the methyl, ethyl and glyceryl esters, as well as abietyl alcohol and esters thereof, such as abietyl acetate and abietyl abietate.  The treatment is preferably effected in an atmosphere of inert gas at a temperature of 150--250 DEG  C.  The products, which are less unsaturated than the starting materials, have a higher melting point and improved colour.  As catalysts, nickel, platinum, palladium and metal chromites are specified, and particularly a palladium catalyst prepared by absorbing a solution of palladium chloride and hydrochloric acid on granular alumina, treating first with formaldehyde solution and then with sodium hydroxide solution to precipitate palladium black and finally washing with dilute acetic acid and water.  Figures are given to show the variation in physical and chemical characteristics of "I" rosin, abietic acid and methyl abietate resulting from the treatment, whilst the drawing shows graphically the different oxygen absorption shown over a period of days by treated and untreated "I" rosin. Nitrates of the methyl esters prepared from treated and untreated abietic acid possess identical melting points.ALSO:An hydrogenation catalyst, used for isomerizing abietyl compounds, is prepared by absorbing a solution of palladium chloride and hydrochloric acid on granular alumina, treating first with formaldehyde solution and then with sodium hydroxide solution to precipitate palladium black and finally washing with dilute acetic acid and water.

Title: Electromechanical resonator comprising a magnetostrictive member
IPC: H01H51/32
Filed: 1955-12-02
Abstract: 782,008. Magnetostrictive resonators. STANDARD TELEPHONES & CABLES, Ltd. Dec. 2, 1955 [Dec. 3, 1954], No. 34570/55. Class 40 (8). [Also in Groups XXXVI and XL (c)] An electromagnetic resonator assembly comprises a resonant magnetostrictive rod supported at a nodal point by resilient means, signal input and output circuits including magnetic circuit associated with said rod, shielding means to isolate the magnetic circuits from each other, and means for applying a magnetic bias to the member. The magnetostrictive member consists of a rod 1, Fig. 1, of nickel or nickel alloy of half wavelength or of odd multiples thereof, and is supported at its mid-point by a resilient washer 7 of rubber or a silicone resin. The input and output coils 2, 4 are enclosed in magnetic cup-shaped shells 3, 5 which increase the flux generated in the rod 1, and the magnetic fields of the two coils are isolated by a ring 6 of a non-magnetic conductor, e.g. copper. The magnetic bias is applied by a permanent magnet 8 having polepieces 9, 10 which operate in association with the magnetic shells 3, 4. A plurality of the resiliently mounted magnetostrictive rods of different lengths, resonating for example at frequencies varying with intervals of ten cycles per second, may be assembled in a brass or synthetic resin block together with a plurality of permanent magnets, and the assembly may be used to analyse the frequencies of a signal applied to the input coils, the output coils being scanned one at a time in rapid succession by a recording device such as a cathode-ray tube. In a further embodiment an alternating magnetic field replaces the permanent magnetic bias at the input coil and is applied by connecting to the latter an altemating current source, a local magnetic field being also applied to the output coil either by a permanent magnet or a second alternating current source: Fig. 5 illustrates a circuit for use when the input signal frequency differs from the resonant frequency of the magnetostrictive rod 37. The input signal is supplied to the input coil 38 through a filter 40 together with a signal, applied through a filter 36, from a local oscillator 35 having a frequency differing from that of the input signal by the value of the resonant frequency of the rod 37. The local oscillator signal is also added to the signal from the output coil 41, and the resultant signal is passed to the output circuit 43 through a filter 42.
