Title: Improvements relating to fountain pens
IPC: B43K5/18
Filed: 1951-07-03
Abstract: 713,536. Reservoir pens. KOVACE, T. July 3, 1951 [July 15, 1950], No. 15741/51. Class 146(3) A reservoir pen, comprising a nib 7, Fig. 1, and a hollow body 3 inserted in the front end of the pen barrel 1 and an overflow chamber surrounding the body 3, is characterized in that the nib or front end of the hollow body hermetically seals the mouth of the barrel and surrounds both an ink duct 8 leading to the nib and also an air channel 9 leading to the overflow chamber. The rear of the hollow body 3 separates the overflow chamber and ink reservoir 4, while the front is a press fit in the end wall 2 of the barrel 1. A feed bar 6 fits in the bore of the body 3 to form the ink duct 8. The duct 8 is connected to a nib 7 slit at 26 by fissures 25 in the feed bar 6 at the front end, and to the overflow chamber by a transverse capillary slit 24. The overflow chamber, comprises annular chambers 13 spaced by partitions 14, the chambers 13 extending from the nib side to longitudinal ridges 15, Fig. 3, forming an air channel 18 having ink fissures 22. The chambers 13 are interconnected by capillary spaces 16 connected to the ink fissures 22 by capillary spaces 17. Air to replace ink used is drawn into the reservoir 4 Fig. 1, through the channel 9 in the feed bar 6, transverse bores 10 and 11 in the feed bar and body 3 respectively, an air channel 12 in the body 3, an annular channel 19 and the channel 18, and through channels 20 and 21. Ink, displaced from the reservoir 4, due for example, to a warming of the air therein, is sucked up by the channels 20 and 18, through transverse slits 23 and chambers 13 and then fills the channel 19. The ink in the channels 18 and 19 must be used up, or returned to the reservoir 4 before air can flow to the reservoir to release further ink. Flooding of the air duct 9 is prevented by the absence of a capillary connection between the space 8 and the bore 10. Ink reaching the overflow chamber from the reservoir 4 owing to shaking of the pen clogs the air channel 18, thereby preventing further ink being released from the reservoir.

The jars, filled, for example, by the machine described in Specification 650,503, and with the cap parts thereon, are supplied by a conveyer 8 and a cam-operated gate 10 to a pocketed wheel 7 which delivers them into registration with plungers 9 on a rotary table 1, the jars being each correctly positioned by a pivoted V-member 30. The plungers 9 are, when fully lowered, flush with the table 1, and each comprise a diering 52 which is raised around the jar to engage, and press inwards, the downwardly directed web 64 of the securing-ring. The upward pressure of each die is resisted by a head 21, the heads being carried by a member 20 which is rotatable in unison with the ring 1. The head 21 is shaped to accommodate the cover and securing-ring and is pressed downwardly by a strong spring 37. The plunger 9 consists of an outer sleeve 50, the upper end of which is formed as the die-ring 52, and an inner part 55 slidable in the sleeve 50 and urged upwardly by a spring 56. The sleeve 50 carries a cam roller 24 which follows a cam 23 on the machine frame 22. The cam 23 first raises the parts 55, 50 together, until the jar is applied to the head 21. The spring 56 is then compressed and the die 52 continues to rise and presses the lower web of the securing-ring under the rim of the jar mouth. The cam 23 then allows the parts 55, 50 to become flush with the table 1 so that the jars may be transferred by the pocketed wheel 14 back to the conveyer 8. Specification 640,962 also is referred to.

Title: Improvements in or relating to chucks
IPC: B23B31/16
Filed: 1929-05-24
Abstract: 322,991. Forkardt, P. Jan. 21, 1929, [Convention date]. Chucks.-Bevel closing chucks operated by a central axially movable wedge have a hook-shaped engagement between the wedge and the jaws so that the jaws may be freed for removal by turning the wedge about its axis. The shape of the engaging surfaces is shown in Fig. 1 and permits manufacture of the parts by grinding, to a high degree of accuracy so that grinding of the jaw faces in situ after changing the jaws is dispensed with. A spring plunger 7 engages a groove in the wedge and normally prevents rotation. When the wedge is rotated to free the jaws by a key applied at 10 the plunger 7 rides out of the groove and its outer end then projects beyond the chuck body thus indicating that the wedge and jaws are not in operative relation. The chuck may be operated by fluid pressure. Jaws.-Spring plungers 9 engage dimples in the jaws and prevent them from falling out when free from the wedge.

Title: Improvements in or relating to Furnaces for the Annealing, Hardening, or like Heat Treatment of Metals, and the like.
Inventor: SMALLWOOD ALFRED
IPC: C21D9/00
Filed: 1917-11-05
Abstract: 120,266. Smallwood, A. Nov. 5, 1917. Charging and discharging.-Metal articles and the like to be annealed, hardened, &c., are introduced into a furnace through a liquid seal and then passed into the heating-chamber by a horizontal movement. Fig. 2 shows a transverse. vertical section through the charging-chamber b and the liquid-seal tank, which are arranged at the end of the heating-chamber a, and which are of a length substantially equal to that of the heating chamber so that rigid goods of a corresponding length may be inserted and removed. The goods are lowered into the open portion of the tank, the level of the liquid in which is indicated at d. They are thus deposited on the bars o of a carrier p mounted on a trolly f, which is then in a position beneath the open portion of the tank. The trolly is the run laterally into the position shown, where it is received into an elevator frame g, which is then raised by a screw h or other means into the charging-chamber. The bars o carrying the goods are then run longitudinally into the heating-chamber, the carrier p being mounted on wheels adapted to run on rails n carried by the trolly. This longitudinal movement is effected by chain-gearing operated by a handle 8, provision being made to allow the vertical movement of the elevator frame and the lateral horizontal movement of the trolly without disconnecting the gearing. When the goods are in the heating-chamber, the frame g is lowered slightly so as to deposit them on the floor, the bars o being accommodated in grooves v. The bars are then withdrawn. In discharging, the operations are reversed.

Title: Mechanism for controlling the transfer of powder or granular material from one piece of plant to another
IPC: B65G47/00
Filed: 1948-06-16
Abstract: 652,481. Hoppers. SPEAKMAN, R. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 16, 1948, No. 16178. [Class 78 (i)] [Also in Groups. V and XXXV] Mechanism for controlling the feed of powder or granular material to extruders, injectionmoulding machines, &c. comprises means for supplying gas under low pressure to a pipe the end of which dips into the powder &c. at the level at which it is desired to control the powder, the pipe being in communication with a pressure-operated switch. The gas passes through the pipe and operates the switch which controls, either directly or by means of a relay, means for feeding the powder. A blower 1 forces air through a bubbler 2, valves 3, 4, a device 5 for interrupting the flow of air and a dip pipe 8, 9, the flanged end 10 of which is in the feed chamber A of an extruder 11 fed by a feeder 12. When the powder in the feed chamber A rises above a certain level the pressure in the pipe 9 rises, and this increase in pressure is transmitted by branch pipe 9a to the space above liquid in vessel 13. A cap 16 is thus lifted, rocking a lever 17 about its fulcrum 18 to operate a mercury switch 14 which, via relay 15, operates the feeder switch to stop the feed. When the cap falls the feed is re-started. The purpose of the interrupter 5 is to prevent chimney formation in the powder. The interrupter is a vessel containing liquid in which a vessel 6 pivoted at 20 and having two compartments 21, 22 is immersed. When one compartment is filled with air from the bubbler the vessel turns about 20 and the gas escapes into pipe 8. This turning movement brings another compartment into position to receive gas. The pipe 7 leads to a second feedcontrol mechanism. Specification 402,655, [Group XXXVII], is referred to.

Filed: 1920-06-19
Abstract: 167,648. Thompson, W. P., (Soc. Anon. des Etablissements Edoux-Samain). June 19, 1920. Self-sustaining gear.-The shaft of a pulley rotates on ball bearings during lifting, but it is prevented from turning during lowering, causing the sheaves to revolve on the shaft with sufficient friction to maintain the load auomatically suspended. As shown, for a differential chain pulley block, the shaft e carrying the integral sheaves f, l, m is permitted to rotate on ball bearings c, d, when hoisting, but is prevented, by the engagement of a pawl i with a ratchet-wheel g on the shaft, from rotating in the opposite direction, thereby necessitating, when lowering, the rotation of the sheaves on the shaft. The guide pulley block also may be similarly constructed. As shown, to increase the friction when lowering, the guide pulley m is rotatably mounted on a large drum p keyed to the shaft q.
