Title: Determination of the alcohol content of exhaled air
IPC: G01N33/98
Filed: 1966-02-21
Abstract: 1,070,199. Determining alcohol in exhaled air. D. JULITA and J. HAYOZ. Feb. 21, 1966 [Feb.24, 1965], No. 7519/66. Heading G1B. In a method of determining the alcohol content of exhaled air, the air is blown over an elongated alcohol sensitive surface 3 in a flat oblong  chamber 1 so that a chemical reaction takes place and produces a zone of a different colour the length of which is dependent on the amount of alcohol in the exhaled air, the quantity of which is limited by an expandible container 5 attached to the chamber 1. The chamber is of translucent material which may be flexible to aid in packaging and contains a strip of material soaked or covered with a layer of the alcohol sensitive material. A mouthpiece 6 is provided and a scale 4 applied to the surface 3 permits the alcohol content of the exhaled air to be read directly. Other embodiments are described in which a number of chambers 1 are disposed radially on a disc attached to associated containers, the disc being rotatable to bring the chambers into view through a window and into connection with a mouthpiece in succession. Also described is a machine in which a strip carrying the alcohol sensitive surface is fed between spools through an elongated flat chamber connected to a mouthpiece at one end and an outlet at the other the strip being moved between each measurement to expose a fresh length of the strip.

Title: Improvements in or relating to transfer mechanism
IPC: B21J13/08
Filed: 1943-05-13
Abstract: 572,332. Forging-machines ; blanks, transferring. WILCOX, R. L., and WATERBURY FARREL FOUNDRY & MACHINE CO. May 13, 1943, No. 7622. [Classes 83 (iii) and 83 (iv)] Transfer mechanism for carrying a work-piece from one station to another comprises a swinging arm bearing a finger coacting therewith to grip and carry the work when actuated by a cam-operated rock-shaft, the finger being adjustable on the arm in the longitudinal direction thereof. As applied to a machine for heading wire blanks, the wire is fed through a die 13, Fig. 3, against an end stop 44 and is cut off by cutters 15, 16 which transfer the blank opposite an ejector 14 and from this position it is transferred opposite the heading die 12, Fig. 1, by an oscillating arm 19 pivoted at 18. A block 20 is adjustably secured to the arm and carries an adjustable finger 21 provided with a notch 25 in which the blank may be held by a latch 22 engaged by a spring 24. The arm is oscillated by a cam 54 having an adjustable segment 35 acting on a lever 37 pivoted at 36 and under the influence of a spring 40, the lever being connected by a link 46 to a rock-shaft 27 carrying an arm 29 acting on the arm 19 through a link 30. Adjustable stops 31, 51 on the machine frame engage opposite sides of a lug 32 on the arm 19 to limit its oscillation in both directions and a spring 50 in the link 46 yields after the stop 51 has been engaged to allow the lever 37 to complete its cam-actuated movement. If the blank A, Fig. 3, is of such a length that it projects beyond the cutting dies 15, 16, the arm 19 is rocked upwardly by the cam to raise the finger 21 above the ejecting station 14 whilst the blank is being ejected, after which it descends, snaps over the projecting blank, and then transfers the latter to the heading die 12. For short blanks as shown in Fig. 3, the thickness of the finger 21 is reduced at 21<1> and the arm 19 stops in its upward position with the notch 25 opposite the ejector so that the blank may be pushed into the finger 21 and then transferred to the die 12.

IPC: H03M1/00
Filed: 1963-02-26
Abstract: 998,337. Automatic phase control systems; tunnel diode switching circuits. MINISTER OF AVIATION. Feb. 26, 1964 [Feb. 26, 1963], No. 7624/63. Headings H3A and H3T. [Also in Division G4] A phase measuring circuit including a frequency divider and means for adding pulses to or inhibiting pulses normally occurring at some point in the divider chain comprises accumulator means for storing the difference between the number of pulses added and the number of pulses inhibited. In the circuit shown in Fig. 1 the output of a stable oscillator 12 is divided and converted into pulses by unit 13, and the pulses normally pass through a gate 10 and a buffer 15 to a further divider 16 and a synthesizer 4 which produces a square wave at the same frequency as an input signal at aerial 1. Signals from aerial 1 pass through a wide band amplifier 2 to a synchronous detector 3 when they are multiplied by the output of synthesizer 4. The output of the detector passes to a filter 5 the output of which is sampled, for example ten times a second, by chopper 6. If the output of filter 5 exceeds a threshold value, either positive or negative, a corresponding pulse generator 8 or 7 is actuated. A pulse from generator 7 closes gate 10, thereby stopping one pulse from passing from divider 13 to buffer 15, a pulse from generator 8 opens gate 11 and thereby causes one extra pulse to be interpolated into the pulses supplied to buffer 15. Pulses from generator 7 and 8 are also fed to a reversible counter 9 which indicates the phase of the signal received by aerial 1 on the time scale of oscillator 12. On starting up, once the counter 9 has reached a stable value it may be set to zero, or some other desired value, and thereafter. the phase will be continuously recorded on the counter. The units 6-8 may be replaced by a Goto twin circuit as shown in Fig. 2. Tunnel diode switching circuits.-The phasesplitter transistor Q, Fig. 2, is normally non- conducting but is periodically made conducting by positive pulses supplied through C1 When it conducts, a voltage pulse is generated across the tunnel diodes D1 and D2 which generate a positive or negative pulse at their junction according to whether an input supplied to the junction is positive or negative.

Title: Process for the production of effects on textile webs
IPC: D06M11/38
Filed: 1935-03-14
Abstract: Crepon and like effects are produced on textile webs by the action of swelling agents with shrinking and/or parchmentizing powers by forming the web from normal vegetable yarns and yarns which are insensitive to swelling agents, by reason of their having natural incrustations thereon or because they have received a specified resist treatment having a similar effect.  Resist treatments specified are (a) impregnation with waterresisting agents, e.g. emulsions of paraffin or higher fatty acid anhydrides, (b) impregnation with solutions of waxes and higher melting fats and hydrocarbons, e.g. beeswax, Japan wax or paraffin in benzine, indiarubber in benzol-toluol, (c) production of coatings by lacquers or resin-like materials, e.g. nitrocellulose in alcohol-ethyl acetate, or solutions of dimethylurea or acetyl cellulose in acetone, (d) surface esterification or etherification in the case of cellulose containing yarn, e.g. by benzoylation or acetylation.  The webs are preferably treated with the swelling agent whilst in a loose condition; the swelling agent may react on the whole of the web, or the web may be first locally printed with a reserve.  The webs preferably contain cotton, but other natural and artificial fibres may be used.  In examples: (1) Cotton muslin comprising effect threads of raw cotton yarn woven in stripes is impregnated with caustic soda solution of 37 DEG  B<\>ae., squeezed, left for 3 mins. unstretched, washed, soured, bleached and dried in a loose condition; the effect threads protrude and impart a crape-like appearance; (2) Cotton muslin having raw cotton yarns woven in warp and weft in a check pattern is printed locally with a gum reserve, dried, and mercerized and finished as in example 1, whereby the reserved parts are brought into relief as patterns on a check base.  A suitable swelling agent having parchmentizing powers is sulphuric acid of 53 DEG  B<\>ae., used for 8 secs.  Other swelling agents are phosphoric acid, mixed acids, well cooled caustic lye, zinc chloride, calcium thiocyanate and ammoniacal copper oxide.  Specification 27361/98, [Class 142], is referred to.

Title: Improvements in folding and measuring machines for fabrics and the like
IPC: B65H45/103
Filed: 1919-04-07
Abstract: 145,182. Mettler, H. W. April 7, 1919. Cuttling. - Relates to machines for laying fabrics in folds of predetermined length by a carriage oscillating between gripping- devices placed over a table, and consists of a machine adapted for any kind of fabric, driven by an hydraulic motor, adjustable abutments being provided to vary the stroke of the piston-rod and consequently of the knife carriage. The laying table 3, Fig. 1, moves in vertical ways 4, and is supported on the piston 6 by an hydraulic ram, the cylinder 5 of which is connected to a pipe 8, through which water is fed to and drawn from the cylinder under control of suitable valves, the table being lowered as the folds of fabric accumulate thereon. Above the table 3 grippers 9, Fig. 5, hold the folds by strips of card-cloth 10, the grippers being connected by arms 11 to hollow shafts 12 rotatably mounted on bars 41 held down by springs 14 connected to arms 13 thereon. The carriage 15 is oscillated in guide-ways 17 by bands 22, 23 passing round a pulley 25 oscillated by a water-pressure motor 28 of known construction, the piston 55 of which has a rack 56 meshing with a pinion 27 on the pulley shaft 26. The carriage has rotatably-mounted knife-bars 19, 20, between which the fabric passes from the guide B, to insert the fabric beneath the grippers, the knives being turned into the horizontal position at the ends of the stroke by toothed connexion to a bar 36 sliding in a disk 37 rotatably mounted on a bolt sliding in a slotted bearing 38 on the frame. To facilitate the insertion, the grippers 9 are lifted against the springs 14 by a chain 33, fixed to an arm on one shaft 12 and to a disk on the other, and running over a pulley 32 on shaft 26. The springs 14 meanwhile exert a braking effect on the shaft 26 to ease reversal. For forming folds of different lengths, the grippers 9 are adjustable by hand-wheels 43, pinions 44, and racks 40, scales 45 showing the position. The length of the chain is correspondingly adjusted by winding it on its supporting disk, which may also be seated. To vary the movement of carriage in agreement, the length of travel of the piston 55 is altered. Means may be provided for giving the carriage a longer stroke after a predetermined number of equal strokes in order to lay a projecting fold of fabric. The grippers may be modified to suit silk and like fabrics, and may consist of gripping- bars pressed together by torsion springs and opened by lever and cam and rack and pinion mechanism from the shaft 26, the table in this case consisting of a horizontal middle part supported by the piston of the hydraulic ram and hinged side parts which slant downwards and on which the folds are dropped when freed by the grippers.
