IPC: G01G13/02
Abstract: 135,096. Morris, J. L., and Allen, C. H. March 14, 1919. Automatic - feed weighers.-Relates to a combination and arrangement of parts whereby a weighing- scale automatically weighs a predetermined quantity of material. supplied from a hopper. A receptacle is placed on the usual platform 4 beneath the supply hopper 7, and a sliding valve 14 is opened by depressing a handle 19. As the weight entering the receptacle increases the usual draw-rod 32 pulls down the short end of a steelyard 24 carrying an adjustable trigger 86. The trigger in its descent thrusts upon a contact bar 61, Fig. 7, which (together with a spring extension 65) is supported in notches between two uprights 57, 58, and the combined contact bar and spring is thus caused to buckle and to close an electric contact 98 so as to energize an electro-magnet 49. An armature 74 pivoted to one end of a lever 75, Fig. 1, is drawn upwards and withdraws a pin from a hole in the sliding valve 14 and the valve then closes under the action of coil springs on a shaft 18. A rod 83, Fig. 7, on the armature thrusts up the contact bar 61 until arrested by a stop 73 and breaks the electric circuit. The falling material at cutoff is compensated for by means of a sliding weight 99 on the short arm of the steelyard, the short arm being notched and graduated for various commodities. The notches may be indexed and a reference tabulation for use therewith may be attached to the machine. Pins 102 limit the movements of the compensating weight 99. Reference has been directed by the Comptroller to Specifications 13343/90, 19925/91, and 20555/93.

Title: Improvements in the dyeing of cellulose acetate artificial silk
IPC: D06P3/40
Filed: 1933-10-11
Abstract: Cellulose acetate, dyeing; dye mixtures.--The dyeing of cellulose acetate artificial silk is effected with the use of a dyestuff preparation, brought into a state of fine dispersion in the usual manner, comprising two or more aminomonoazo dyestuffs of the general formula <FORM:0428841/IV/1> (wherein R and R1 represent residues of the benzene series and the dialkylamino group is in p-position to the azo group) which dye similar shades, at least one having only a weak or moderate affinity for the artificial silk.  The dyestuff preparation may be obtained by using a mixture of suitable components for the production of the dyestuffs, or by dissolving the individual dyestuffs in a common solvent and precipitating the mixture in a finely divided state, or by finely grinding a mixture of the dyestuffs, or by adding the finely divided dyestuffs to the same dyebath.  The following examples are specified.  (1) A solution of diazotized 4-nitro-2-chloraniline is added to a mixture of diethylaniline and dimethylaniline in hydrochloric acid solution, the solution is neutralized with sodium acetate and stirred until coupling is complete and the precipitated dyestuff mixture is filtered, washed and dispersed to provide a dyebath from which the artificial silk is dyed an intense bordeaux red; the diazo component may be wholly or partially replaced by 1-amino-4-nitro-2-methoxybenzene or by homologues or other substitution products of aniline; solid preparations containing the dyestuffs and a dispersing agent such as sulphite cellulose lye may be obtained by evaporation.  (2) A solution of diazotized p-nitraniline is added to a mixture of diethylaniline and dimethylaniline in hydrochloric acid solution, coupling is completed and the dyestuff mixture is filtered, washed and dispersed as in (1) to provide a dyebath from which the artificial silk is dyed an intense orange.  (3) Cellulose acetate artificial silk is entered into a dispersion of the dyestuff mixture in (1) obtained by stirring the mixture into a 6 per cent soap solution and pouring into lukewarm water, the temperature is raised to 75--80 DEG  C. during \ba3/4\be hour, dyeing is continued at this temperature for a further \ba3/4\be hour, and the material is rinsed and dried to obtain an intense bordeaux red dyeing. Specification 219,349, [Class 2 (iii)], is referred to.

Title: Improvements in or relating to apparatus for producing audible signals
IPC: G08B3/10
Filed: 1940-08-31
Abstract: 543,590. Signalling by audible signals. COMPTON ORGAN CO., Ltd., J., and FAIR. W. T. H. Aug. 31, 1940, No. 13682. [Classes 40 (i) and 118 (ii)] Apparatus for producing audible signals, particularly air-raid warnings, comprises an electric sound generator rotated by a motor, and means for alternately energizing and deenergizing the motor thereby varying the speed of the generator and producing a note of undulating pitch. The generator may be of the kind described in Specifications 403,444 and 433,050 in which a number of rings are employed to generate undulating electric potentials. The generator is rotated by an electric motor 4 and is connected to a source of potential 2 and one or more loudspeakers 3. The motor is connected to a source of power 5 through a throwover switch with two sets of contacts one of which, 8, is connected to the motor by leads 6, 7. When the contact is closed, the motor rotates at a steady speed and the " all clear " signal is given by the loudspeaker 3. The contacts 12 are connected to the motor by leads 9, 11, and contacts 10 which are opened and closed intermittently to vary the speed of the motor to give the "take-cover" signal. This is effected by a centrifugal governor 13, on the shaft of the motor, which is provided with a disc 14 that moves axially along the shaft. The disc oscillates a pivoted arm 15 which is connected by a blade spring 19 with another pivoted arm 16. One end of the arm 16 operates the contacts 10, and the other end is provided with a stop 21 that engages a stop 20 on the arm 15. In operation, when the contact 12 is closed, the speed of the motor increases and the arm 15 is rocked. At a particular speed, the stop 20 moves clear of the stop 21 and the spring 19 moves the arm 16 to a position at which it opens the contacts 10. The speed of the motor then decreases until the stop 20 has again moved clear of the stop 21 when the spring 19 moves the arm 16 to a position at which the contacts 10 are closed. If desired, the contacts 10 may be replaced by a mercury switch mounted on the arm 16. A multi-pole switch 23 may be provided to enable any generator ring, or selection of rings, to be connected to the source of potential 2 so that any tone pitch may be produced. The sound produced may ' be made intermittent, for " imminent peril" warnings for example, by operating a pair of contacts 26 by a rotating cam 27. A number of cams may be used to repeat a given cycle of tone pitches, and according to the Provisional Specification the device may be arranged to transmit Morse signals.

Abstract: 297,486. Johnson, J. Y., (Magee Carpet Co.). May 24, 1927. Overedge stitches.-The unselvaged edges of pile fabrics are bound by a three thread overedge stitch shown in Fig. 20. The needle-thread 61 is passed obliquely through the fabric from the back and lies between the pile tufts as shown in Fig. 6. A binding tape d may be enclosed by the stitching. Machines with work-benders; loop stitching; needle shields; feed by presser feet and the like. -The pile fabric is placed face downwards on a rotary table 32, Fig. 15, and the edge is bent down into a channel between the edge of the table and fixed guides and a feed foot 13. The needle-thread loop is entered by a threaded looper 48, the thread loop of this looper is entered by a second threaded looper 47 and the thread loop of the latter looper is carried over the upper surface of the fabric and is entered by the needle. The loopers 47, 48 are carried by levers 55 and 57 pivoted at 53, 58, connected by a link 56, and are actuated from the main shaft by a crank 49 and link 51. The lever 57 carries an arm 59 which serves as a take-up for the thread of the looper 47 on the lever 55. This thread passes through a resiliently mounted eye 69. Similarly an eye on the lever 55 serves as a take-up for the looper 48. The needle-bar is mounted in an oblique plane. A stationary finger 40 supports the needle laterally when it is penetrating the oblique surface of the fabric. The feed foot 13 is carried by a feed-bar 16, Fig. 12, which is below the level of the work-support and is actuated by an oscillating arm 14 and a lift cam on the shaft 4. The arm 14 and its shaft 15 are oscillated by connection to an arcuate slotted lever 22 and the amount of feed can be varied from zero upwards by means of a treadle connected to the link 21 by a chain 29. The rotary table 32 is mounted on a work-plate 33 which is pivoted at one end and is pulled by a weighted chain 33a so as to press the rotary table towards the fixed work-guides. One of the fixed guides 37 may be tubular so as to serve as a guide for a binding tape. Stopping-gear.-The treadle 41, Fig. 16, operates both the driving clutch and the feedadjusting mechanism. In its first movement a roller 43 acting on a cam edge of the lever 44 sets the machine in operation. Further movement does not affect the clutch and is used for moving the feed regulator.

Title: Testing device for threaded assembling means or fasteners
IPC: G01L5/24
Filed: 1970-03-23
Abstract: 1307286 Extensometers SOC DES AUTOMOBILES SIMCA 23 March 1970 [2 April 1969] 14012/70 Heading G1S When a bolt V is to be tested to determine its elastic limit for example, it is turned by a torque spanner against a reaction plate P and pulls an endpiece E vertically upwards causing a tube 10 to be stretched slightly, the tube being integral with a fixed and clamped base 12 and integral with a screw threaded part 13 surmounted by a cap 15 holding the end-piece E. The tube 10 communicates via sealing members 18, 19, with a glass capillary tube 20 supporting a slidable marker 22 and a bulb 21 containing inert gas, and with a tube 24 in which a plunger 29 may be moved by a micrometer arrangement 25, 26. The tube 10, tube 24 and most of the capillary tube 20 are filled with mercury, so that a torque on the bolt V stretches the tube 10 and increases its volume. This causes some of the mercury in the tube 20 to enter the tube 10. By moving the plunger 29 further into the tube 24 the mercury may be caused to move back to its original position in the tube 20, and the micrometer is calibrated to measure tensile force. By removing the bearing R the plate P may bear directly upon the head 40 of the main casing so that if tests are made with and without the bearing R in position it is possible to determine the effect of friction at the bearing face of the bolt head for each clamping torque to calculate the friction at the thread. By changing the end-piece E and/or the ring 45 the device may be used to test nuts and so on.
