Filed: 1917-02-07
Abstract: 111,395. Lutiger, K., and Wirz, E. A. Feb. 7, 1917. Disk apparatus; milling-cutters, sharpening; driving and feed devices; gauges; tables etc.; trueing rotating tools.-In a machine for grinding the backs of the teeth of screwing-taps and of milling- cutters, the work is mounted between a spindle stock b, Fig. 2, and tail stock e carried on a table f<1>, which can be adjusted about a pivot f<2> on a transverse slide f controlled by springs c<2> to hold the work against the grinder k. The slide f is carried by a slide d, which can be traversed longitudinally by a rack d<1> and pinion d<3>, and is carried by a vertically adjustable stand u. The spindle stock has a loose sleeve b<2> mounted on the spindle b<1>, and on the loose sleeve are carried a worm gear g, a pattern cam a corresponding to the shape of the back of the teeth, and an indexing-plate h<1>. The cam a is engaged by a bowl c' carried by the slide d, and is provided with a circular slot a' and stops a<2>, between which an arm on the work spindle moves. The cam is adjusted relatively to the work and then the loose sleeve b<2>, is coupled to the spindle b<1> by a pin h<2> on a part secured to the shaft engaging a hole in the indexing-plate h<1>. The work is traversed across the grinder and is then turned slightly by the worm wheel g and another traverse made. The worm wheel g is turned by a worm g<1> carried by a hand-lever g<3> so that it can be put into or out of gear. The grinder is carried on a shaft k' adjustable longitudinally on a table k<3> pivoted at k<4> on the top of a column capable of adjustment about a vertical axis. A. bracket i carries a spindle i<2> at right-angles to the axis of the grinder. On this spindle is mounted a trueing- tool i<3>, which is held out of action by a spring i<4> but which can be advanced across the tool. This tool i<5> also serves as a gauge to adjust the position of the grinder. To grind milling-cutters &c. with helical teeth, the loose sleeve on the spindle stock carries a gear wheel meshing with a pinion on a grooved shaft s, Fig. 4, parallel to the spindle. A pinion s' slides on this shaft and engages a quadrant s<4> mounted in a stand s<5> on the pivoted table s<8>. The quadrant s' carries a guide-finger s", which engages with the end of one of the helical teeth on the cutter t. As the work is reciprocated in front of the grinder, the stand s<5> is caused to remain in one position by a fixed pin s<10> engaging a hold s<9> in the stand. Any movement of the loose sleeve on the spindle to adjust the work between the traverses in front of the grinder is communicated to the segment s' and guide-finger s<17>. The work is held against the guide-finger by a spring n<1>, Fig. 6, wrapped round the boss n<2> of a loose sleeve carrying an arm n<3>, in which is mounted a pin n<4> adapted to engage a hole in a plate n<5> keyed to the spindle. The spring can be wrapped round in either direction to allow for the grinding of right or left hand cutters &c.

Title: Improvements in the production of solid calcium nitrate
IPC: C01F11/44
Filed: 1929-01-25
Abstract: 325,364. Smith, C. -C., and Imperial Chemical Industries, Ltd. Jan. 25, 1929. Solid calcium nitrate is produced by mixing a strong solution of calcium nitrate with nitric acid, and the crystals precipitated, which may be separated by centrifuging, are washed by a suspension of chalk in calcium nitrate solution of such strength that the adherent acid is just neutralized. According to a preferred form of the invention, nitric acid of, say, 50 per cent strength is saturated with calcium nitrate, or nitric acid is added to calcium nitrate, and the temperature adjusted so that there is equilibrium between the solid and the solution, and a calcium salt, for example, calcium carbonate is added together with an equivalent amount of nitric acid; or oxides of nitrogen are passed into the solution to which chalk is added continuously, unabsorbed oxides being recirculated through the system. The oxides of nitrogen may be obtained by the oxidation of ammonia, part of the gases issuing from the oxidation plant being diverted through the solution as above described. The residual nitric acid solution may be employed for the preparation of, say, sodium, potassium, and ammonium nitrate.

Patent GB-620824-A (GB)
Title: Improvements in or relating to hypodermic syringe and ampule
IPC: A61M5/24
Filed: 1947-01-28
Abstract: 620,824. Hypodermic syringe. DOLDER, E. Jan. 28, 1947, No. 2583. [Class 81(ii)] In a hypodermic &c. syringe including a cylindrical ampoule &c. inserted in the casing and closed at both ends by plugs or a plug and cap, the front plug or cap being punctured by the injecting needle and the rear plug serving as a plunger by means of a plunger rod, the plunger is made of elastic material and provided with means for axial compression and radial expansion to vary the sealing pressure of the plunger against the wall of the ampoule and permitting the syringe also to be used for withdrawing liquid. The syringe comprises a casing 1 into which the ampoule plug 2 or cap and a rear closure plug 3 is inserted, the plug 2 being punctured by the cannula 6 when operating the syringe. The rear plug 3 is provided with a bolt 9 having a head 10 and passing through a washer 12, the end of the bolt being engaged by a nut 13 having two lateral inclined faces 14 and recessed portions by means of which the plunger 3 is gripped and operated by the plunger rod 15 in the form of a tube. One end of the plunger rod is secured to the handle 16 and the other end is slotted at 17 to form two resilient parts adapted to engage the nut 13 to operate the plunger 3. The plunger rod 15 is provided with an axially movable bar 24 having an arrow head 26 by means of which the resilient parts of the plunger rod 15 may be forced apart when it is desired to disengage the plunger rod 15 from the plunger 3. When it is desired to vary the sealing or sliding pressure of the plunger 3 against the glass casing 4 the plunger bar 15 is engaged with the nut 13 and rotation of the bar 15 varies the axial compression, and therefore the radial expansion of the plunger 3. In this way when the syringe is used to withdraw liquid into the casing 4 the plunger 3 on completion of its stroke may be compressed so that the liquid is sealed in the casing 4 which may then be removed from the syringe. The front plug 2 may be arranged to vary the sealing pressure by axial compression and radial expansion. In a modification the disengaging bar 24 is in the form of a tube within which is a rod having a nib engageable with the nut 13 whereby the nut may be turned by manual manipulation of the rod.
Patent GB-377939-A (GB)
Title: Liquid measuring device with twin-piston
IPC: B67D7/16
Filed: 1931-01-27
Abstract: 377,939. Delivering measured quantities of liquids. FABRIK EXPLOSIONS - SICHERER GEFASSE SALZKOTTEN GES., Salzkotten, Westphalia, Germany. Jan. 27, 1931, No. 2639. Convention date, Jan. 30, 1930. Void [Published under Sect. 91 of the Acts]. [Class 106 (v).] In liquid measuring apparatus of the piston and cylinder type the piston is formed double and encloses a space 4 in communication with the atmosphere, into which leakage past the piston flows and may be indicated. Fig. 3 shows a form in which the leakage flows into the space below two separate measuring cylinders with interconnected pistons and is indicated in a sight glass 47. The transparent measuring cylinder 1, Fig. 1, is provided with a double piston 2, 3 comprising cup leathers clamped to a piston body 5 forming between them the cavity 4 in communication with the hollow piston rod 11b by passages 11. The upper and lower chambers of the cylinder 1 are alternately connected with the supply duct 16 and the outlet duct 17 by a four-way valve 7. Any liquid leaking through the cup leathers runs off through the hollow piston rod. Alternatively the leakage may escape through a small hole or groove arranged in the side of the cylinder 1 level with the top of the lower piston 3 when in its upper position. The cavity 4 between the pistons may be filled with liquid of a colour different from the liquid being measured, or with a liquid for preserving the leather e.g. glycerine, castor oil &c., and communicate with a stand-pipe 53, Fig. 4, having at its upper end a sight glass 54 level with a sight glass 60 interposed in the outlet duct 16 and having an overflow pipe 62. A duct 55 controlled by a cock 57 allows of the removal of any air accumulating below the upper piston 2. Any leakage is indicated by rise or fall of level in the sight glass 54. Fig. 3 shows a form having pistons 33, 34 operating in separate cylinders and connected by a lever 42 and rods 40, 41. The space 4 communicates with the outside by a pipe 23, sight glass 47 and overflow pipe 51. A small bore 30 in the overflow pipe allows slight leakage to escape directly but considerable leakage is indicated in the sight glass. In this modification the valve 7 may be operated automatically by the increase of pressure in the measuring chamber when the piston reaches the end of its stroke. Adjustable abutments 43, 44 limit the stroke of the pistons which are guided by ribbed members 29 working in tubes 36 on the cylinder covers. The invention may be applied to apparatus having horizontal cylinders and to arrangements of measuring cylinders in a circle, the pistons being moved in succession by rotating driving mechanism which also operates the reversing valves.
