Title: Method for the manufacture of a tubular knitted article
IPC: D04B15/34
Filed: 1971-07-14
Abstract: 1362028 Knitting-machines G BILLI & C SpA 14 July 1971 [20 July 1970] 32927/71 Headings D1C and D1K A circular knitting-machine includes sinker cams at each feed mounted on slides 21, and a control ring 37 having profiled apertures so that the slides can be selectively moved radially to alter the stitch length. Each slide carries a screw with a disc-like head 35 projecting into a corresponding aperture. Alternate apertures have a profile surface 37B, 37C at different arcuate positions. By means of a pivoted control lever 41 the ring can be set so that alternate slides are reset by surface 37B, or all slides reset by movement to greater arcuate extent so that surfaces 37C are effective also. When knitting a ladder proof fabric alternate slides are advanced so that alternate courses comprise large stitches. These courses include held stitches in a 1:1 array the held stitches being displaced in successive held courses.

Title: Improvements in or relating to digital reproducing systems
IPC: G11B20/20
Filed: 1963-08-20
Abstract: 1,021,449. Electric digital data-storage. AMPEX CORPORATION. Aug. 20, 1963 [Aug. 21, 1962], No. 32972/63. Heading G4C. [Also in Division H3] Data pulses reproduced from number of bidirectional magnetic tape transport mechanisms are deskewed by feeding them to selected taps of delay lines, gated from selected ends of the latter and sent over differential current conductor means to a central data processor where they are amplified. Fig. 2 shows details of the units used for one channel of one tape. The tape transducing head feeds the two terminals at the left with oppositely-varying signals by means of appropriate couplings, e.g. a phase splitter. The signals pass to a difference amplifier 34 comprising two transistors 35, 36 fed by a constant current source 38. The outputs from the first amplifier 34 go to the bases of two transistors 41, 42 forming a second difference amplifier 40, the output of which (at the collector of 42) goes to the variable tap 52 of delay line 50. The two ends of,the delay line 50 are connected respectively to the inputs of two further transistor difference amplifiers 58, 62 acting as selector gates. The amplifiers 58, 62 are normally biased off by negative voltages on lines FWD, REV but when the central data processor requires data from that tape unit, one of the lines FWD, REV is made positive, depending on the direction of tape movement, thus allowing pulses from the appropriate end of delay line 50 to pass through the selected difference amplifier 58 or 62 to the lines (shown dotted) communicating with the central data processor. Thus the data signals are transmitted to the central data processor over a pair of lines (per tape channel) as differential current variations, unaffected by line variations and transient voltage spikes. Some of the amplifiers in the central data processor are also shown in Fig. 2, on the right.

Title: Improvements in electron trigger circuits
IPC: H03K3/10
Filed: 1945-12-06
Abstract: 614,328. Valve-generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 6, 1945, No. 33074. Convention date, July 27, 1944. [Class 40 (vi)] A two-valve multivibrator circuit, with one stable state comprises a transmission line or delay network which is connected to one of the valves so as to control the duration of the unstable state in the oscillation cycle. In Fig. 1, valve V2, in the normal stable state, is conducting and valve V1 is non-conducting. Positive triggering pulses may be applied to the grid of valve V1, causing this valve to conduct and valve V2 to be cut-off. The negative pulse from the anode of valve V1 which is transmitted to the grid of valve V2 charges a delay network or transmission line TL. This transmission line is terminated at one end by the resistor Rd2 which is equal to its characteristic impedance, and short circuited at the other end, so that a pulse of opposite polarity is reflected back along the line. When the reflected pulse arrives at the grid of valve V2 this valve starts to conduct, and the circuit reverts to stable state conditions. The duration of the output pulse of the multivibrator is thus equal to twice the time delay of the transmission line, and very short pulses may be produced. Several modifications are described when the delay network is connected across either of the anode loads or other parts of the circuit to produce the same result. A modified form of multivibrator (Figs. 6 and 7, not shown) is also considered. Fig. 8 shows a capacity resistance cross connection, whereby single or multiple pulses may be produced for each input pulse, according to whether the time constant CR is short or long relative to the delay of the transmission line TL. Specification 602,267 is referred to.

In a method of making high-strength steel wire by cold drawing, the wire is given an intermediate spheroidization anneal. A rolled steel wire is uncoiled, cold drawn 60-80% reduction in section and passed to a wire accumulator, after which it is heated by induction or an electric current and rapidly cooled when it has reached the spheroidization temperature to form a spheroidized pearlite structure. After cooling, the wire is led into a second accumulator whereupon the steps of cold drawing, annealing and rapid cooling may be repeated at least once. After the final cooling step, the wire is further cold drawn and recoiled. The wire may be annealed in the coiled state.

Filed: 1935-12-03
Abstract: Thiobarbituric acids substituted in the 5-positions by a primary isobutyl group and by a saturated or unsaturated alkyl group are prepared by condensing the corresponding malonic acids or their derivatives with thiourea, or with isothiourea ethers and subsequent saponification; or by introducing the two groups simultaneously or in succession into thiobarbituric acid by treatment with reactive esters of the corresponding alcohols; or by condensing such derivatives of the disubstituted malonic acids as the cyanacetic acids and esters with thiourea and its derivatives, and converting the products into the thiobarbituric acids e.g. by saponification.  The products possess therapeutic properties.  According to the examples: (1) 5-primary-isobutyl-5-allyl-thiobarbituric acid is prepared by condensing primary-isobutyl-allyl-malonic acid diethylester with thiourea in the presence of sodium alcoholate, or by saponifying with dilute sulphuric acid the product obtained by condensing primary-isobutyl-allyl-cyanacetic acid methylester with thiourea in presence of sodum alcoholate; the 5-ethyl, butyl or crotyl-5-primary - isobutyl - thiobarbituric acids are similarly obtained; (2) 5-primary-isobutyl-thiobarbituric acid, prepared by reacting isobutylmalonic acid ester with thiourea, is heated in the form of its sodium compound with allyl bromide in benzene, preferably in the presence of copper bronze as catalyst; the product consists of primary-isobutyl-allyl-thiobarbituric acid; (3) the latter compound is also obtained by slowly adding methylthiourea-ether hydroiodide and caustic soda solution to a benzene solution of primary - isobutyl - allyl - malonyl chloride with cooling and then heating with concentrated hydrochloric acid.
