Filed: 1925-01-02
Abstract: 234,441. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 23, 1924, [Convention date]. Leading-in wires.- The joint between a metal disc or cap employed in sealing a leading-in wire to a vacuum-tube &c. and the glass of the tube is cooled by a current of air &c. introduced along the leading-in wire; the disc is so shaped as to reduce the risk of electric discharge in the neighbourhood of the joint. In the form shown in Fig. 1, the cap 12, of chrome-iron or like material is sealed to a tube 11 forming part of the vacuum tube and projecting into it. The leading-in wire 4 is surrounded by a glass or other tube 6 provided with a union 8 by which a current of air can be directed down the tube 6 against the cap 12. The wire 4 may consist of a copper tube connected to the cap 12 bv a suitable junction-piece perforated for the passage of air, when the tube 6 may be dispensed with. The cap 12 is of conical form as shown, so as to provide an edge 19 from which electric discharge may take place instead of from the neighbourhood of the joint. Fig. 4 shows a tube with three electrodes to which the invention is applied.

Title: Automatic feed mechanism for drill-presses
IPC: B23Q5/32
Filed: 1921-01-05
Abstract: 156,684. Sipp, G. July 10, 1917, [Convention date]. Drilling, - In a power-driven drilling-machine having manually operated means for positioning the drill spindle, improved means are provided whereby the power feed is automatically engaged and disengaged at predetermined points, the spindle being finally returned to its starting position by spring pressure. The spindle d driven from cone pulleys c rotates in a sleeve f, secured by collars against axial movement on the spindle and having rack teeth engaged by teeth on a shaft j carried in a vertically adjustable frame-arm g to position the spindle by hand. The spindle is normally kept in its upper position by means of a weight or by a spiral spring p. A vertical shaft s belt driven from pulleys on the driving sleeve e drives through spur gearing located within a housing r, a shaft having a worm driving a worm wheel 6 loose on a reduced extension of the spindle j. Pinions 15 carried on studs between a plate 11 keyed to the spindle j, and a ring 12 engage spur teeth 8, on the worm wheel 6 and internal teeth on a ratchet ring 16. The arrangement is such that, when the ratchet ring is held against rotation, the planetary gearing causes rotation of the shaft j through the keyed plate 11. The member 16 is controlled by a pivoted pawl 22 operated by a spring toggle device 25, as shown in Figs. 8 and 10. The pawl is rocked to lock the wheel 16 to start the power feed by means of a pivoted dog 34 mounted on a vertical rod adjustably secured to the spindle sleeve and sliding in a guide 32 on the gear carrier. After a predetermined travel a toe 38 on another adjustable member on the spindle sleeve strikes an arm 29 to turn the pawl out of contact with the ratchet ring to stop the power feed, whereupon the spindle is returned to its upper position by the spring p.

Title: Improvements in marine condensers and the like
IPC: F28B9/04
Filed: 1920-01-06
Abstract: 165,484. Sandford, W. H. Jan. 6, 1920. Surface condensers.-In a surface condenser for marine use, in which a vacuum can be produced on the sea-water side of the tubes 4 greater than that on the steam side, so as to prevent leakage of sea-water into the tubes, the sea-water is drawn by a pump 1 on the exhaust side through an adjustable throttle valve 6 on the inlet side. An air chamber 7 is connected to the sea-water header 2 to preserve a constant vacuum. An automatically-acting by-pass valve may be fitted to the inlet pipe so as to admit additional sea-water if the vacuum becomes too low. This valve may be operated by a piston connected with the steam space of the condenser so as to maintain a constant difference of pressure between the steam and sea-water sides of the tubes.

Title: Improvements in or relating to Ignition Devices for Internal Combustion Engines.
Inventor: CODD MORTIMER ARTHUR
IPC: F02N99/00
Filed: 1916-01-11
Abstract: 102,998. Codd, M. A. Jan. 11, 1916. Transformers.-An ignition set consists of a rotary coil having primary and secondary windings 11, 12, a condenser 13, a contact breaker coaxial with the soil, and a distributor in close juxta-position with the coil so as to avoid intermediate wiring. The driving-spindle 1 has one of the platinum contacts 2 clamped thereto, the other 4 being carried by a spring plate 5 attached to the collar 6 which is secured to the spindle 1. An extension 32 on the plate 5 wipes against the recessed underside of the plate 30 in the fixed cover 16, thus making and breaking the contacts 2, 4. The timing is adjusted by an arm which projects from the member 31 through the cover 16. Primary current is led in by the terminal 21, spring-pressed brush 24, conductor 26 insulated in the end of the spindle, and lead 28. The coil spool consists of the collar 6, flanges 7, 9, and a tubular portion 8, the whole being longitudinally split to prevent eddy currents. The cap 15 has screwed into it a core of soft iron 20, serving both as the core of the coil, and as a long bearing whereby a separate bearing at the contact-breaker is unnecessary. One end of the secondary coil is connected to a metal strip 36 secured in the surface of the coil by a wrapping of ebonite paper and cotton which overlaps a flange on the strip. As the coil rotates the strip makes contact successively with the points 37 of the distributor terminals. The terminals consist of a split spindle, on which screw members 44, 45 with brass bushings 46, 47. The part 45 has a lateral enlargement with a passage 48 for the sparking-plug conductor. Both ends of the secondary coil may be insulated, each being brought to a plate 36, each plate engaging a set of distributor points so that two plugs, each with one electrode earthed, may be employed in each cylinder.

Title: Method and apparatus for producing fibrous structures

IPC: B29C41/00
Filed: 1960-01-11
Abstract: 902,817. Agglutinated fibrous materials. ROSENWALD, L. J., ROSENWALD, J., and SCOTT, I. M., [trading as WALSCO CO.]. Jan. 11, 1960, No. 948/60. Class 140. [Also in Groups V and IX] A mat is made from animal, mineral, e.g. glass, vegetable or synthetic fibres by subjecting the fibres to an electrostatic charge in a charging area, transferring them to a place removed from the area and subjecting them to an electrostatic charge of opposite polarity to the charge thereon to deposit the fibres in mat form. Fibre-bonding materials, e.g. synthetic resins in liquid, powdered or granular form are incorporated, e.g. by spraying or immersion, at any stage of the mat production or subsequent thereto. In the operation of the apparatus shown in Fig. 1, glass filaments 20 fed from heated spools 21 are stapled to any predetermined length by an adjustable cutter 13, the fibres fall through a rotating distributer bar 14 and are guided by a funnel 15 to fall past and be correspondingly charged by electrodes 37. If a solid bonding resin is introduced into the funnel 15, it is subjected to the same subsequent processing as the fibres and cured when the mat is formed. The charged falling fibres are collected on an earthed rotating drum 30 or a conveyer belt (not shown) and are transferred by electrostatic attraction to a conveyer belt 34 made of insulating material and charged by a depositing corona electrode 40, in the form of wire or metal plate, of opposite charge to the fibres. The mat which thus forms on the belt 34 and is continuously reproduced according to the outline of electrode 40 may then be electrostatically transferred to another belt or be cured and mechanically removed. The rate of fibre delivery to electrode 37, the speed of belt 34 and the shape of electrode 40 may be adjusted to control the thickness, density and/or shape of the mat. As shown in Fig. 4, a modified drum 30a of insulating material houses an electrode 41 which is earthed or maintained at a potential of opposite polarity to the charge on the fibres. An earthed brush 42 removes excess charges on the surface of the drum and fibres transfer to an uncharged metal depositing surface 34a. If the fibres collected on the drum are to be transferred to an insulating surface, then another charged electrode 43 is provided. As shown in Figs. 5 and 6, the depositing electrode is formed of metal foil pattern 39 on an insulating belt 38 or drum (not shown).
