Title: Method of and apparatus for presizing glass tubing
IPC: C03B23/055
Filed: 1945-03-07
Abstract: 588,793. Sizing glass tubing. FORRESTER, H. J. C. (MacGregor Instrument Co.). March 7, 1945, No. 5668. [Class 56] Relates to a machine for making the internal and external diameters of cut lengths of glass tubing to predetermined sizes, the tubes then being used, for example, for hypodermic syringes, stop cocks, or flow meters. The machine comprises a disc 37 carrying four arbors 39 equally spaced around its periphery, the frame thus formed being counterbalanced and manually swingable as a whole about a shaft, not shown, to and from inoperative and operative positions. In the inoperative position, a cooled sized blank is removed from the appropriate arbor and a new blank B is positioned thereon, the inner end of the blank abutting against a shoulder 48 on the arbor. The disc is now rotated through a quarter turn and is swung into its operative position wherein the newly-positioned blank is subjected to a preliminary heating, the arbor carrying the previously-positioned blank now being at the second station at which the blank is further heated and sized internally and externally, whilst the third and fourth arbors, each carrying a blank which has been positioned still earlier, are at cooling stations. The preliminary heating is by means of a ribbon burner 52 and the arbor carrying the blank at this station is rotated by friction gear from an electric motor. At the sizing station the blank is acted on externally by three rollers 69 positively rotated in engagement therewith about inclined axes and carried by a carriage 61 clutchable to a constantly running endless chain, whereby the carriage moves from left to right across the machine and the rollers 69 traverse the blank. Oxy-gas burners carried by the carriage heat the blank under treatment and the blank is constantly pushed against the shoulder 49 by a pressure cap 63<1> carried by a second carriage which is pulled by a weight in the opposite direction to that of the carriage 61 to compensate for the decrease in the length of the blank due to the thickening of its walls in conforming internally to the diameter of the arbor and externally to the distance between the pressure rollers. The travel of the carriage 61 in its forward direction is automatically arrested by a stop and this mechanism is also used to cut off the supply of oxygen to the burners and to declutch the carriage from the driving chain. The carriage is manually restored to its left-hand position and manual means are provided to reclutch the carriage to the chain and to re-open the oxygen supply. Means are also provided to move the rollers 69 axially slightly when removing the arbor and blank from the sizing station and positioning the next arbor and blank therein.

Abstract: 184,512. Cooklin, I., and British & Foreign Industrials, Ltd. Feb. 10, 1921. Expanding tables.-Removable leaves 7 are automatically inserted by the operation of screw, chain, or like mechanism between end parts 1 of the table top and an intermediate part 10 mounted on slides 15 with tongues 16 which work in grooves in the framing 2 carrying the parts 1. The leaves 7 carry bearers 30 and are stowed in undercut recesses 17, 5 formed in the slides 15 and frames 2. The operating-screw 25 works in a nut 27 carried by a frame 28, 26, 21 connected to the framing 2 of the end of the table remote from the screw 25. To remove the leaf 7 from this end, the screw is turned.back so as to open the dowelled joint at 14, Fig. 3, the leaf 7 remaining attached to the part 10 on account of the friction between the bearers 30 and the underside of the part 10, until the joint at 14 is well open, when a projection 8 depending from the leaf 7 comes in contact with a pin 9 on the frame 2 which pulls the leaf off the dowels 13 and lets one end drop against a projection 6 on the frame 2, the other end resting on a block 31 on the slide 15. The movement of the screw 15 is then reversed to cause the parts 15, 2 to approach the other, when the block 31 moves away from under the bearer 30 and allows the leaf to pass into the recesses 17, 5. Specification 1374/15 is referred to.

Title: Improvements in edging machines for timber
IPC: B27B5/24
Filed: 1925-03-04
Abstract: 245,310. S÷rensen, E. F. March 4, 1925. Addition to 239,892. Tables and fences.-In a timber-trimming machine the lateral adjustment of the work 3 relatively to the trimming saw 2 is controlled by the action of selecting arms 8 which are pivoted under spring action so as to feel the edges of the work as it is moved past them, in which motion it is guided by a fence 5. Arms 10 rigidly attached to the selectors 8 operate racks 14, 18, 20 to adjust the sliding carriage of a roller 21 which co-operates with a conically faced cam 22. Ratchet and pawl gear (not shown) is arranged to prevent the return of the racks, so that the depth of the deepest recess encountered by the selectors determines the displacement of the roller 21 along the face of the cam 22, which in its rotation operates levers 24 and moves shafts 28 longitudinally, rollers 4 being mounted on the shafts which press on the work and adjust it laterally. Between the displacement of the roller 21 and its operation by the cam 22, the selectors 8 are withdrawn by the action of eccentrics 38, 39 and the fence 5 is moved out of the way by the action of eccentrics 59. A cam 75 subsequently raises the rollers 4 by means of levers 33, and a spring 36 is provided to draw the levers 24 and shafts 28 back to their original positions. During the operation of the selectors the work is not fed directly by the usual feed chain 60, but by means of an arm 63 carried by a sliding rod 62 moved against a weight 71 by a bell-crank 66 held so as to be engaged by the feed chain by a latch 67, which at a suitable point is tripped by a stop 70 so that the work is released for its lateral adjustment by the action of the rollers 4. Immediately afterwards the work is picked up by the feed chain and carried on to the trimming tool. Two sets of selectors 8, 9, Fig. 2, are provided, the upper set being horizontally and vertically adjustable by means of worm gearing 46, 52 respectively, with hand wheels 49, 55, so that timber of various thicknesses can be accommodated, and variously inclined edges can be cut. The lateral motion may be communicated to the tool instead of to the work, by arranging the lever 24 to adjust the position of a sliding carriage upon which the trimming tool and its driving motor are mounted.

Title: Improvements in variable speed power transmission mechanism
IPC: F16H61/664
Filed: 1922-03-01
Abstract: 181,682. Ribetti, E. June 16, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Variable-speed friction gearing suitable for motor vehicles comprises a disc 2 driving separately two rollers 4, 5 which are movable in unison to vary speed and are adapted to allow differential movement automatically so as to dispense with balance gearing. The roller shafts 6, 7, which are geared to drive the road wheels, are supported at their inner ends in block 10, which is normally pressed by a spring 11 towards the disc 2. The rollers 4, 5 are connected through bell-crank levers 12 and links 13 to a beam 14, which is moved parallel to itself to vary the speed from a hand-lever 15. The automatic action is accompanied by a tilting of the beam 14. The spring 11 is compressed to disconnect the driver by a pedal 17. When the rollers 4, 5 are moved inwards past low-speed position, they come opposite a recess 18 in the disc 2. Pressure on the pedal 17 then brings them into engagement with a disc 3 on the engine shaft 1, so that each is driven reversely to its previous motion, and the vehicle travels backwards.

Title: Improvements in automatic protective systems for alternating current circuits
IPC: H02H3/34
Filed: 1931-02-26
Abstract: 376,250. Protective cut-out arrangements. JOHNSON & PHILLIPS, Ltd., Victoria Works, Charlton, and STIGANT, S. A., 41, Crantock Road, Catford, both in London. Feb. 26, 1931, No. 6090. [Class 38 (v).] In the protection of A.C. circuits, particularly overhead lines, against earth fault, the several phases (or the outgoing and return lines in the case of a single-phase circuit) are taken through a common transformer core which is provided with secondaries equal in number to the lines, each secondary being connected in series with the operating element of a circuit disconnecting device located in each of the lines via an auxiliary circuit disconnecting device. The primary windings are arranged so that with healthy conditions they balance one another whereas in the event of an earth fault the secondaries increase the current through the operating element of the disconnecting device and open the circuit. The protective system is applicable mainly to a supply system with an earthed neutral although this is not necessary with extra high voltage circuits. In the arrangement shown in the Figure for a three-phase circuit using fuses FA, FB, FC as the disconnecting devices, the transformer core has three primary windings PA, PB, PC and three secondaries SA, SB, SC. The secondaries are each connected in series with a main circuit fuse through an auxiliary fuse such as FAI. In the event of an earth fault, the current in the secondary such as SA assists the main current through the fuse FA to cause its rupture. The main circuit is completely interrupted when the auxiliary fuse ruptures subsequent to the rupture of the main fuse. The main line current through the main fuse may normally be neutralized by the current from a current transformer CTA in the main line thus leaving only the currents of the balancing transformer to blow the main line fuses. In a modification, one secondary only on the balancing transformer is used and is connected to an intermediate core having a number of secondaries equal to the number of lines.

Title: Improvements in or relating to impulse repeating devices for automatic and semi-automatic telephone exchange systems
IPC: H04Q1/36
Filed: 1927-03-04
Abstract: 267,499. Telefonaktiebolaget L. M. Ericsson, (Assignees of Ericsson Polska Akcyjna Spolka Elektryczna). March 9, 1926, [Convention date]. Automatic exchange systems. - An impulserepeating relay 8, Fig. 1, connected in series with an auxiliary battery 9 of smaller voltage than the main battery 5 is bridged across an incoming loop 2 in parallel with the battery 5 and choking coils 3, 4. This gives an arrangement in which, as the resistance of the loop varies from zero to infinity, the current in the relay 8 varies progressively from a maximum negative value to a smaller maximum positive value, and the relay 8 is adjusted to respond only to currents within the neighbourhood of the latter value. It will therefore operate when the loop is opened (or is connected in series with a high resistance) to transmit an impulse and such an arrangement will not be adversely influenced if used in a system in which the resistances of the lines of trunks vary considerably as in a rural-exchange system. The bridge circuits are preferably so balanced that the resistance for which the current in relay 8 is zero corresponds to the average resistance of an impulsing loop. The relay 8 may be polarized or non-polarized, but if the latter type is used the minimum resistance of impulsing loops must be greater than that :at which the value of the negative current in the relay becomes greater than the value for which it has been adjusted to operate; otherwise, the relay will be operated both when the loop is closed and when it is open and it will not, there. fore, respond to impulses. This feature may be employed for preventing certain subscribers from establishing particular connections by making their loops of such low resistance that they are unable to transmit effective impulses for such connections. Fig. 5 shows the application of the invention to a repeater. When an outgoing trunk is seized, relay RR operates and connects up relay HR which locks up and energizes relay ER. The latter completes the outgoing loop and connects the two windings of relay 8 to the incoming terminals 6, 7 and to the potentiometer 26 which supplies the auxiliary voltage 9, Fig. 1, from the main battery. At each impulse, relay 8 operates substituting a high-resistance loop through slowacting relay VR and coil Si for the direct loop over contact 13. At the end of the connection, prolonged energization of relay 8 causes relay VR to operate and release relays HR, ER. In modifications, the relay HR is dispensed with and choking coils are inserted in series with the relay 8 and in parallel across the terminals 6, 7.
