IPC: F41A19/13
Filed: 1965-02-01
Abstract: 1,063,506. Automatic pistols. HECKLER & KOCH G.m.b.H. Feb. 1, 1965 [Feb. 18, 1964], No. 4286/65. Heading F3C. An automatic pistol has a body 1 which supports an interchangeable barrel 2 and carries a breech block carrier 5 having a breech block 4. A firing pin 8 adapted to be struck by a hammer 14 is carried in an oversize bore 7 in the breech block and the tip thereof is accommodated in a central aperture 21 or in an eccentric aperture 22 formed in a plate 15 secured to the breech block by a screw 16 according to the type of ammunition to be used. If the pistol is to be used with a different type of ammunition the barrel merely has to be changed and the tip of the pin 8 placed in the appropriate aperture. There may be a number of eccentric apertures formed in the plate 15 and the latter may be integral with the breech block. The pin 8 is guided in one of the apertures 21, 22 by a thickened portion 8a formed thereon and is also guided in a safety roller 11 inserted in a crossbore of the breech block. A sloped portion 13 of the roller is so shaped that rotation of the latter in the counter clockwise direction lowers the rear end of the pin out of the path of the hammer 14. The pin 8 may bo removed from one aperture and inserted in another by laterally removing the roller 11. Alternatively a slot may be formed in the lower part of the breech block through which the rear end of the pin could be removed after the pin had been pushed forwardly to compress spring 9. If a removable plate 15 is provided, that may be removed to permit the spring pin to be inserted in another aperture thereof.

Title: Safety arrangement for electrically heated vessels
IPC: H01H37/00
Filed: 1961-02-06
Abstract: 921,199. Thermal switches. W. BRANDL. Feb. 6, 1961 [Feb. 5, 1960], No. 4383/61. Class 38 (5). A sealed vessel 1 containing a liquid 2 and a heater 4 is connected to a bellows 5 so that when a certain temperature is reached, the bellows expands and operates a microswitch 7 to cut off the heater. In case the switch fails to operate, it is pivotally mounted at 14 on a bracket 13 and is biased clockwise by a spring 17, so that excessive pressure in the bellows can overcome the spring 17 and move the switch 7 counter-clockwise about its pivot. Thus a bracket 25 carried by the switch 7 moves from a position in which further series contacts 21, 22 are held closed, allowing the contacts to open to de-energize the heater.

Patent GB-229678-A (GB)
Title: Process for the production of alkali cellulose
Filed: 1925-02-18
Abstract: Cellulose to be converted into alkali cellulose is treated one or more times with the waste lyes from a preceding operation; and finally with fresh lye of mercerizing strength.  Operating in this manner, the hemi-celluloses are more completely extracted, with the result that the viscose prepared from the alkali cellulose is of higher quality and the silk produced therefrom is of high strength and gloss; thus, by the process, it is possible to prepare viscose from celluloses which, by reason of their high hemi-cellulose content, could not otherwise be used.  The process of treatment may be carried out on the counter current principle, or in a series of vessels arranged on the plan of a diffusion battery, or in centrifugal apparatus.  After each treatment the lye may be brought to its original concentration as regards caustic alkali.

Title: Auxiliary shutoff valve apparatus for flow control valve housings
IPC: F16K7/20
Filed: 1958-02-12
Abstract: 883,462. Stopping pipes. RHEINISCHES METALLWERK G.m.b.H. Feb. 12, 1958 [Feb. 13, 1957], No. 4649/58. Class. 99(1). [Also in Group XXIX] An auxiliary shut-off valve apparatus for a main valve housing 10 comprises an auxiliary casing 14 screwed on to a connecting stub pipe 13 and a closure member 18 which can be advanced into the flow passage of the main valve housing 10. The closure member consists of a rubber bag surrounding a hollow pin 17 which in turn is secured to a piston 15 in a chamber 20 in the auxiliary casing 14. A further piston 16 is attached to a spindle 21 in threaded engagement with an end cap of the easing 14. A flat link chain 22 connects the two pistons. The space between the pistons is filled with an hydraulic pressure medium. On screwing in the spindle 21 the piston 16 attached thereto causes the piston 15 to move the closure member 18 accross the flow passage of the main valve housing 10. Further movement of the pistons 16 causes an increase in fluid pressure in the space between the pistons and this increased pressure inflates the rubber bag 18 surrounding the pin 17 in to sealing engagement with the walls of the passage through the main valve. The main valve housing 10 is threaded at 11 into a clip, which is then clamped around a gas or water main. The pipe is bored through the housing 10 and when this is done the boring machine is moved back as far as possible and the passage sealed by the auxiliary shut-off valve apparatus as described above. The boring machine can then be removed and the closure member of the main valve fitted. The auxiliary shut off valve apparatus can be then unscrewed and a branch pipe substituted.

IPC: A47J27/08
Filed: 1968-01-30
Abstract: 1,201,712. Pressure cooker. A. VISCHER. 30 Jan., 1968 [30 Jan., 1967], No. 4819/68. Heading B1X. [Also in Division F2] The supply of clean steam to, and the withdrawal of drainagefluidsfrom, a pressure cooker 11, is effected by means of a solenoidoperated three-way valve 28 working in conjunction with a drainage valve 27, respectively, both valves being actuated automatically and in the desired sequence. Upon closing of a switch 41 and setting of a timer knob 39, and hence rotation of a cam 36, closing of contact 45 is achieved, which closing results in solenoid 24' being actuated and valve 24 opened to permit the passage of steam to the cooker. At the same time the cooker pressure is low, the bellows 33 decompressed, contact 42 closed and therefore solenoid 28' actuated, such actuation moving valve 28 into its first position in which it closes passage 27' and so permits drainage of fluid from the cooker 11 to exhaust, via line 26, valve 27 and line 25. Subsequently, upon the cooker pressure reaching a certain predetermined value, this pressure is transmitted, via line 34, to the bellows 33 which expands opening contact 42 and closing contact 50. This deenergises coil 28', transfers valve 28 into its second position in which it permits steam to pass to the drainage valve 27 via line 27' in order to close the flow between lines 26 and 25, and energizes motor 35 which rotates cam 36 for the period of time set by the timer knob 39. A cam-follower 37 then engages a notch 38 in the cam 36, contact 45 is opened, and hence solenoid 24' de-energized and valve 24 closed and contact 46 is closed so again energizing coil 28' and returning valve 28 to its first position to permit the discharge of fluids through valve 27. The drainage valve 27 is so constructed, (Figs. 2 to 5, not shown), that steam, when present in line 27', acts on one side of a diaphragm (56) so urging it against a seat formed at the end of inlet line 26 thereby blocking communication between it and line 25, the absence of steam resulting in the diaphragm being urged away from the seat by a plate spring (63). In all states of the drainage valve, the steam and drainage fluids are separated from each other by the diaphragm.
