Abstract: 406,210. Sewing - machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. Aug. 10, 1933, No. 22351. Convention date, Dec. 27, 1932. [Class 112.] A work-support for sewing-machines arranged in tandem to to bind the edge, and stitch a fringe to, a rug comprises a series of rollers 105 which are inclined at an angle to the direction of feed and tend to force the work against an edge-guide 63. The tops of the rollers are slightly above the workplates to allow the rug to droop. Feeding long lengths of fabric.- The fringe is wound on a card 77 which is mounted between spindles 79, 79<1>. The spindle 791 is driven at a somewhat slower speed than the card rotates, by a pulley 95, the halves of which are spring pressed against the spindle. Work guides.-The fringe is led across a swinging bar 85 and under a stud 89 to an inclined delivery plate 67 which is formed with an edge guide 70, a fringe-edge-confining lip 71 and a depending rug-pile fin 72. The fringe fibres are deflected from the needle by a foot 94. The edgeguide 63 is flared at 64, 66. Feeding work by rollers.-The rug is fed by an intermittently driven roller 33 and a spring pressed roller 34. The roller 33 is mounted on a shaft 35 and given a step-by-step rotation by a main shaft eccentric 37, a pitman 38 and a clutch roll driver. A second clutch roll device prevents back rotation. Grouped machines.-The machine shafts S<1>, S<2> are connected by a chain C. Longitudinal slots 9 in the front machine base 3 and lateral slots in the rear machine base allow of relative adjustment of the machines. Specification 14799/07, [Class 112, Sewing &c.], is referred to.

Abstract: 1401297 Analysis using enzyme bound hapten etc SYNTEX ENERGY RESEARCH Inc and VARIAN ENERGY 15 May 1972 [14 May 1971] 22778/72 Heading G1B A method of detecting a ligand in a medium comprises contacting in a liquid phase the medium, an enzyme-bound ligand and a soluble receptor for the ligand, the enzyme-bound ligand being capable of competing with the ligand for the reception sites of the receptor and comparing the enzyme activity then obtained with that obtained for a mixture of the same amounts of enzymebound ligand and of receptor. The interaction of the enzyme-bound ligand with receptor reduces the enzyme activity. The ligand may be a monomeric or polymeric material, especially a drug, a cell or virus. The receptor may be an enzyme, antibody (obtained when the ligand is hapten using as antigen the ligand linked to protein), RNA, DNA, or a naturally occurring receptor such as thyrobinding globulin. Examples disclose the detection of codeine using carboxymethyl morphine-amylase and morphine antiserum assaying the amylase using a suspension of dyed amylose, the measurement of Pysozyme activity in morphine-lysozyme using a suspension of dried bacteria, Micrococcus lysodeikticus in sodium phosphate pH 7.0, the effect of addition of meperidine on the inhibition of activity in lysozyme-meperidine by addition of BSA-meperidine antiserum, the effect of addition of phenobarbital on the inhibition of activity in a phenobarbital-lysozyme BSA-N-carboxymethyl phenobarbital antiserum, the detection of testosterone using testosterone-3-carboxymethyl oxime-maleate dehydrogenase and antibody, assaying using oxalacetic acid and NADH, the assay of barbiturate in a synthetic urine (described) using phenobarbital - or secobarbital-lysozyme and antibodies to BSA, conjugates of analogues to these barbitals, a substrate for determination of horse-radish peroxidase (HRP) prepared by forming a leuco-dye by reaction of toluic acid p,p' -dimethylamino benzophenone, converting this to the mixed anhydride and adding this with pyridine to a DMF solution of polyvinylalcohol at 100C, the resulting polymer giving a blue colour with HRP.

Title: Improvements in or relating to telecommunication installations
IPC: H04B3/10
Filed: 1946-08-01
Abstract: 633,068. Automatic volume control. COMPAGNIE GENERALE D'ELECTRICITE. Aug. 1, 1946, No. 23008. Convention date, June 9, 1945. [Class 40 (iv)] The gain of receivers in a multiplex system is controlled by an A.C. pilot in the form of impulses transmitted successively over the various channels. The frequency of the pilot may be just outside the band of voice frequencies and may be a carrier frequency. A pilot signal generated at 6 is interrupted at 7 and the impulses after filtering at 11 are distributed at 10 to the various channels. The interrupter 7 is operated by a relaxation oscillator 8 controlled by the distributer 10. In each channel a band-pass filter 2 accepts the voice signals and blocks the passage of the pilot in the backward direction. The pilot and the voice signals are modulated at 3 with a carrier generated at 4 and the channel is filtered at 5 before transmission. The process is reversed at the receiver where the pilot signal filtered at 16 and detected at 17 is used to control the gain of an amplifier 15. If two stages of modulation are employed, the pilot may have the same frequency as the carrier common to the first modulation step of all the channels and may be injected into the channel at the second stage of modulation. At the receiver, the pilot is extracted after the first demodulation at 25 (Fig. 2) and is employed to control the gain of the amplifier 15 after the second demodulation. The interrupter 7 may be a relay in the anode circuit of the relaxation oscillator 8, which is disabled whilst the distributer brush is moving between contacts. The relay may be replaced by an attenuator fed rectifier biassed by the anode current of the oscillator. The Specification as open to inspection under Sect. 91 describes an arrangement in which pilot signals of different frequencies are distributed over the different channels. This subjectmatter does not appear in the Specification as accepted.
