Title: Improvements in or relating to the drawing of glass threads
IPC: C03B37/081
Filed: 1945-12-11
Abstract: 605,001. Glass threads. VERSIL, Ltd., and LAYCOCK, W. H. Dec. 11, 1945, No. 33501. [Class 56] Glass threads are formed by feeding a glass rod downwardly into a fusion receptacle which is open at the top, converges to terminate in a nozzle at the bottom, and is heated externally intermediate the top and bottom so that the rod melts on contact, and the molten glass fills the receptacle and rises to form a semi-fluid seal around the rod, which exercises a piston effect on the glass beneath to force it through the nozzle. As shown, the glass rod 1 is moved downwardly into the fusion receptacle 2 comprising refractory stone 15, heat resisting steel lining 16 and a platinum ring nozzle 17, which is heated in the chamber 3 to between 850- 1100‹ C. The glass melts, fills the receptacle, rises as indicated at B, and partially solidifies to form a seal 9 round the rod, which presses the glass 11 steadily through the nozzle to form the spinning point 13 from which the thread 14 is formed. The chamber 3 has a lining of refractory stone 4, 5, with outer cover 8, and insulation 6, 7 which prevents radiation into the cooling zone 9 and the drawing zone 20. A number of receptacles 2 arranged in any pattern may be heated in a common chamber.

Title: Improvements in shock-absorbers
IPC: F16F9/48
Filed: 1936-12-07
Abstract: 486,205. Hydraulic shock absorbers. KIMBER, A. W. Dec. 7, 1936, No. 33532. [Class 108(iii)] In a piston-and-cylinder type of shock-absorber in which resistance to the piston is effected by the flow of fluid through a series of ports of progressively decreasing areas, the hydraulic resistance tc the rebound of a spring is applied only when such spring has, after receipt of a sudden shock, regained its normal flexure, such resistance increasing progressively in proportion to the extent of the rebound. In the position shown, the spring supporting the vehicle is in its normal position When the spring is compressed the piston E moves toward the end of the cylinder D and liquid is discharged through the space between removable ring h and end g of the cylinder and also through the ring of non-return valves p in the piston without applying resistance to the plunger. On the rebound, the piston moves back to its normal position without encountering any resistance and thereafter covers ports k<1>, k<2> ... M<1>, M2 in succession to apply a gradually progressive resistance to the plunger. Tapering slots may replace the holes k<1> &c. in the walls of the cylinder. A reservoir C<1> in the cover forms an oil reservoir and communicates through non- return valve q with the cylinder. A filling plug u and channel t communicates with the cylinder and a slotted vent e is formed at the top end of the cylinder D and communicates with the oil reservoir formed between the two cylinders A, D.

Abstract: 950,395. Feeding webs. BLANDIN PAPER CO. Aug. 31, 1962, No. 33594/62. Heading B6B. In a web roll unwind and transfer mechanism, the replacement or primary web roll is rotated at a peripheral speed equal to the speed of the running web before splicing. Figs. 12, 13 and 14 show three modes of operation of the mechanism. In Fig. 12, a web X is drawn from a secondary web roll B supported in the open bearings 47 of a secondary support 19 pivoted about the axis 44. A primary web roll A is loaded on to a primary support 18 from guide faces 31. In Fig. 13, the primary support 18 is pivoted about the axis 23 and the web roll A is rotated by a motor and clutch system, Fig. 5 (not shown), so that the peripheral speed matches the speed of the web X. A dabbing roller 105, rotated at a peripheral speed equal to the web speed, is swung on arms 19 to splice the running web X against the adhesive equipped primary web roll A. A knife 136 severs the web X below the splice. The web X continues to feed from the primary web roll A whilst the secondary support lowers the exhausted secondary web roll B on to a transverse conveyer 22 comprising a continuously moving belt 148a. Pads 146, 147 stop the rotation and guide the secondary web roll B on to the conveyer. In Fig. 14, the primary web roll is transferred to the secondary support 19 thus becoming the secondary web roll B. The drive of the web roll is taken up by a motor and clutch system, Fig. 1 (not shown). Two Selsyn generators associated respectively with the motors of the primary and secondary supports, synchronize the speeds of the motors so that the web roll can be transferred whilst rotating at a constant speed. The supports return to the position shown in Fig. 12 after the web roll has been transferred.

In a press for forming sheet-metal blanks 26 between a form 80 and an elastic wall 15 under hydraulic pressure in a chamber 14 to which pressure is applied by a plunger 20 entering the chamber 14 the assembly of the chamber 14, elastic wall 15 and plunger 20 is mounted in a press head 2 which can be raised from the operating position at which it is normally locked. The press-head 2 is slidably mounted on columns 5 and carries a cylinder 19 to which pressure is applied through a pipe 25 connected above a piston 21 to force the plunger 20 into the chamber 14 and deform the elastic wall 15 over the metal blank 26. The press-head 2 is normally locked in the lowered position by split collars 37, 38 surrounding each column 5 and engaging below adjustable nuts 39 which are locked in position by nuts 40 when the cross-head 2 is set at the correct height. For raising the cross-head a pneumatic cylinder 3 attached to the tops of the columns 5 is supplied with compressed air so that its piston 29 lifts the cross-head 2 to which it is attached through a connecting-rod 30. For lowering the cross-head 2 pressure is supplied to an hydraulic cylinder 4 mounted above the cylinder 3 and containing a piston 33 which is coupled to the piston 29  through a connecting-rod 34 and over-rides the  pneumatic lifting pressure. The split collars 37, 38 are pivoted on pins 41, 42 and rotated through arm 45 to open and release the crosshead 2. Hydraulic cylinders 36 actuate the arms 45, all of which are coupled together for simultaneous operation through links 46 and a  radial armed member 48 which rotates about the  link 30. The former 80 is mounted within a tool holder 12 on the press table 1. A blank holding ring 81 surrounds the former 80 and is yieldingly supported by pins 11 resting on a disc 55 engaged by a piston 54 in a cylinder 52 to which pressure is normally applied from an  hydraulic accumulator through a line 60 during  actuation of the press or to eject the blank 26.  If higher pressures are required, a pneumatically actuated valve 66 with an intensifier portion 65 raises the return pressure from the cylinder 52. Locking of the ejection means during a portion of the upward stroke of the press is provided by an hydraulic piston 67 connected to the piston 54 through a rod 58, and held in position when required by a solenoid-operated valve 77 which prevents fluid-flow through passages 70, 71 interconnecting the fluid above and below the piston 67. Specification 771,257 is referred to.
