Title: Improvements in stop-motion or signalling devices, operative on fracture of filament, for warp beaming and other apparatus in which sized or wet-dressed filaments are fed over rollers
IPC: D02H13/00
Filed: 1939-05-30
Abstract: 529,357. Warp beaming machines &c. SUCKER GES., GEB. May 30, 1939, No. 15932. Convention date, June 7, 1938. [Class 142 (iv)] In a warp-beaming or other machine for treating a number of filaments in the form of a ribbon or band, the filaments travel over a roller on which broken ends tends to wind and an electric contact, disposed adjacent the roller, is closed by the thrust exerted thereon by a broken filament and causes the closing of a circuit whereby a signalling and/or stop motion device is actuated. As shown, the filaments f in the form of a warp in their passage to and from a drying chamber 18 pass over rollers 6...12 and finally pass through a pivoted comb 15 to be wound up on a beam 17; when a fracture occurs in a filament approaching a roller 6...12 the bunch formed on the roller causes a pivoted contact 25 resting against the roller to be pushed against a contact 27 and a circuit containing an electric bell 20 and an electro-magnetic cut-out 21 for the driving motor 22 to be closed. If a bunch is formed at the comb 15 the latter is tilted and closes contacts 23, 24, the closing of the contacts also causing the bell to be rung and the driving motor to be stopped. Specification 334,242, [Class 120 (ii)], is referred to.

Title: Terminals for welding connection
IPC: B23K9/23
Filed: 1969-03-27
Abstract: 1,213,922. Welding by fusion. AMP Inc. 27 March, 1969 [12 April, 1968], No. 15983/69. Heading B3R. [Also in Division H2] The end of a wire 12 composed mainly of one metal, for example Al or an Al alloy, is welded to the flush end of an inner sleeve 24, composed mainly of the same metal, of a coaxial pair of sleeves, the outer sleeve 22 of which is composed mainly of another metal, for example Cu or Cu in brass. The sleeves form part of an electrical coupling and are press-fitted, forged or crimped together. The method of welding, described in Specification 1,074,695, comprises the steps of contacting the flush ends with a coaxial electrode E, passing a current at a low voltage through sleeve 22 via an integral portion 18, and drawing electrode E away from the ends to initiate an arc which triggers the discharge of a capacitor to give a large welding current. In the case where portion 18 blocks the path of a coaxial electrode, an electrode with an oblique end is used to contact the flush ends (Fig. 5, not shown). Portion 18 is formed as an apertured flange (Figs. 1-6). It may be replaced by a flange having ribs (64, Fig. 7, not shown) and overhanging side walls. Alternatively, the outer sleeve may have no flange, and merely comprise a nickel or gold plated sleeve crimped to the inner sleeve (72, Figs. 8, 9, not shown). An insulative cap may be snapped over the weld bead. In all cases, an insulative sleeve 30 is provided which shrinks on to wire 12 during welding.
Patent GB-645390-A (GB)
Title: Improvements in and relating to the production of artificial protein threads, filaments and the like
IPC: D01F4/00
Filed: 1948-06-15
Abstract: Freshly spun artificial protein threads are hardened in a bath containing formaldehyde and one or more metal salts other than sodium chloride and then treated at a temperature of from 35 DEG  to 60 DEG C. in an insolubilizing bath containing from 500 to 800 grams of sodium bisulphate and from 5 to 15 grams of formaldehyde per litre. Suitable metal salts are sodium sulphate, magnesium sulphate, and aluminium salts such as aluminium sulphate.  Threads so treated have improved resistance to attack by boiling water and hot dilute acids. The insolubilizing bath may also contain free sulphuric acid up to 200 grams per litre, and the time of insolubilizing treatment is usually from 1 to 4 hours.  The hardening step (which may be effected in one or two stages with stretching in between them) is carried out at 40 DEG  to 70 DEG  C. in a solution of pH 3.0 to 8.0 and containing 5 to 15 grams formaldehyde per litre.  The time of treatment is from 1 to 4 hours.  Both the hardening and insolubilizing treatments may be carried out on thread-advancing reels in the baths or on a continuous thread in a series of convolutions.  In an example a 17 per cent solution of milk casein in an aqueous 1.2 per cent caustic soda solution is extruded into a coagulant bath containing 360 grams sodium sulphate and 40 grams sulphuric acid per litre. It is then stretched and hardened simultaneously, the hardening taking place in two stages, the first in a bath containing per litre 300 grams sodium sulphate, 10 grams formaldehyde and 5 grams sulphuric acid for 15 minutes at 45 DEG  C., the second in a bath containing per litre 250 grams sodium sulphate and 10 grams formaldehyde for 10 minutes at 55 DEG  C.  It is then fed continuously through an impregnating bath at 50 DEG  C. containing per litre 400 grams of sodium sulphate and 10 grams formaldehyde, and then fed in convolutions into a hardening bath of the same constitution and at the same temperature, and hardened for two hours.  Excess hardening solution is removed by squeeze rollers and the thread fed in convolutions into an insolubilizing bath at 40 DEG  C. containing per litre 400 grams sodium sulphate, 352 grams sulphuric acid (equivalent to 676 grams sodium bisulphate and 76 grams sulphuric acid) and 10 grams formaldehyde.  After 2 hours treatment in this bath the thread is washed with water and 0.5 per cent aqueous sodium bicarbonate and dried.  Specifications 502,710, 565,011 and 597,497 are referred to.  The Provisional Specification also refers to Specification 618,925.

Abstract: 1397614 Suction lifting devices EATON CORP 12 April 1972 [15 April 1971] 16871/72 Heading B8H [Also in Division F2] A pick-up assembly for use in moving articles comprises a pick-up head (10) having an array of suction cups (20), the head (10) being mounted on a stacker crane (12), Fig. 1 (not shown), each cup 20 having a control assembly 34 associated therewith whose function is to maintain those cups 20 of the array which are in engagement with an article to be lifted in communication with a vacuum source, but to ensure that those cups 20, which are not in engagement with the surface of an article, are not in communication with the said vacuum source. When the suction cups are in engagement with the surface of an article to be lifted a plurality of switches are closed, each switch 110 being in an electrical circuit 100 in the control assembly 34 of each cup 20, Fig. 7. The closing of a switch 110 activates an oscillator 112 which delivers a pulse P1 of a predetermined duration to a solenoid 54 which causes a plunger 56 associated therewith to be moved to the left in Fig. 3 thus opening a ball valve 48 against the action of a spring 60 and permitting air to pass through a passage 38 to a low pressure chamber 44 which is in communication with the vacuum source. If a particular cup 20 is in sealing engagement with an article the pressure in the associated passage 38 drops and a cylindrical plunger 72, whose one end is in communication with the passage 38 and whose other end is in communication with the atmosphere through a passage (90), Fig. 4 (not shown), is moved to the left in Fig. 2 thus depressing an actuator button 78 in a switch 68 which closes and thereby connects the associated solenoid 54 to a D.C. source, Fig. 7, the solenoid 54 maintaining the associated valve 48 open by means of the plunger 56 at the end of the period of the pulse P1. In order to release the cup 20 from the article a switch 120, Fig. 7, is opened to interrupt the flow of current to the solenoid 54, the plunger 56 retracting and the ball valve 48 resetting under the action of the spring 60. If on the other hand a particular cup 20 is not in engagement with an article, on actuating the associated solenoid 54 by means of the pulse P1 the valve 48 is opened by means of the plunger 56 but as the passage 38 is in communication with atmosphere there is no difference in the pressure at the two ends of the associated plunger 72 which therefore does not move to actuate its switch 68, and at the end of the pulse P1 the plunger 56 is retracted thus allowing the ball valve 48 to reset, thereby closing off the passage 38 from the vacuum source. Associated with each cup 20 is an indicator lamp 134, Fig. 7, mounted on a display panel, Fig. 8 (not shown), such that when the associated switch 68 is closed owing to the engagement of the cup with an article the lamp 134 is lit.
