Title: Improvements in or relating to gas valves
Inventor: LINDEN NICO VAN DER
IPC: F23N5/10
Filed: 1969-03-28
Abstract: 1,203,914. Burner control systems. HONEYWELL Ltd. 28 March, 1969 [30 March, 1968], No. 16318/69. Heading F4T. [Also in Division F2] A gas valve has a closure element 22 movable in response to tilting motion of a first lever 31 to open and close a gas passage 44, 45, a second lever 28 with which the first lever is normally constrained by a latch connection 33 for joint tilting motion, first control means 12 operable to tilt the second lever, and hence the first lever when the latch is engaged, to the open position against a primary bias 5 which tends to tilt the levers to the closed position, a device 7 to restrain the primary bias from moving the second lever once it is in the open position with the effect of rendering the first control means ineffective, and second control means 11 operable to release the latch connection, the arrangement being such that release of the latch while the device 7 remains actuated causes the lever 31 alone to tilt to the closed position under the influence of a secondary bias 32, thereafter reopening of the passage being dependent upon re-engagement of the latch. The two levers are pivoted on a stationary axis 26 and are normally constrained to move in unison by the latch 33 which consists either of a blade of resilient material or of a rigid blade hinged at 36 to the lever 27. When the control means 12 is pushed manually downwards, the levers are rotated clockwise by a projection 18 to open the valve 22 and are held in the open position by a solenoid 2 of the device 7 which is energized by a thermo-couple heated by a pilot burner connected to a duct 46. A duct 48 connected to the main burner or to a servo system controlling a valve between a passage 45 and the main burner is kept closed by a valve 40 until the means 12 is released. When the control means 11 is pushed manually downwards, the latch is disengaged and a spring 32 rotates the lever 31 relative to the lever 28 to the position shown in Fig. 3 so that the means 12 remains ineffective to re-open the valve 22 until the solenoid 2 has released an armature 3 and allowed a spring 5 to re-engage the latch. The danger of supplying gas to an unlit burner due to the valve 22 being opened manually and held open by the solenoid when the latter remains temporarily energized by thermal inertia in the system is thus avoided. The blade 33 may be of bi-metallic material to cause the latch to become disengaged if excessive temperatures occur within the valve housing.

Title: Improvements in the manufacture and production of chlorbutadiene
IPC: C07C17/08
Filed: 1935-06-12
Abstract: Chlorbutadiene is made by passing gases containing vinyl-acetylene (which may be obtained by passing electric-arc acetylene over a solid catalyst containing a cuprous compound) together with hydrogen chloride over active carbon in the presence of halogen compounds of base metals of the second or fourth groups of the periodic system, such as mercuric and mercurous chlorides, bromides and iodides, and lead, cadmium, zinc, and stannous chlorides.  The halides may be mixed with one another or with metallic mercury, and may be made in situ by charging the active carbon with the free metals.  The reaction may be effected at 50--200 DEG  C. in the dry state or in presence of steam.  Instead of hydrogen chloride, substances liberating it may be used, such as a mixture of phosgene and steam. Examples describe the use of active carbon containing calomel, metallic mercury, cadmium chloride and lead chloride respectively. Dilute vinylacetylene is used in each case.  Specification 451,442 is referred to in the Provisional Specification.

Abstract: 1,164,098. Rotary-piston internal combustion engines. NSU MOTORENWERKE A. G. and WANKEL G.m.b.H. April 10, 1968 [April 15, 1967], No.17194/68. Heading F1F. In a rotary-piston I. C. engine of the trochoidal type comprising a housing having a peripheral wall with a multi-lobed inner surface and end walls and in which a multi-cornered piston is mounted for planetary rotation with the piston corners in sliding engagement with the inner peripheral surface to define variable volume working chambers, and induction and exhaust ports in the peripheral wall and/or the end walls, a pre-exhaust port is provided in the peripheral wall and/or end walls ahead of the exhaust port in the direction of piston rotation which is connected by a pre-exhaust passage to the exhaust pipe. As shown, a threecornered piston 5, Fig. 1, planetarily rotates within a housing having a peripheral wall with a two-lobed epitrochoidal inner surface 2 and peripheral induction and exhaust ports 8a, 10a and a peripheral pre-exhaust port 11 connected by a passage 12 to a muff 13 encompassing the exhaust pipe 10 and communicating with the pipe 10 through holes 14, so that the much hotter exhaust gases issuing from the preexhaust port 11 heats the cooler main exhaust gases to inhibit the formation of harmful compounds in the exhaust gases. This may also be assisted by a hot insert 15 in the exhaust pipe 10. The formation of harmful compounds in the exhaust gases may be further inhibited by introducing additional air into the exhaust pipe. To avoid the use of an air pump a four-cornered piston 5<SP>1</SP>, Fig. 2, which planetarily rotates within a housing having a three-lobed inner peripheral surface may be used. Air is admitted to the engine working chambers through a port 18 in an end wall of the housing and after compression by the piston expelled through a peripheral port 19 and a passage 20 to a further muff 21 which surrounds and communicates with the exhaust pipe 10. Instead of the further muff surrounding and communicating with the exhaust pipe it may surround and communicate with the pre-exhaust passage 12. The exhaust pipe in passing through the housing wall may be insulated therefrom to still further inhibit the formation of harmful compounds.

Filed: 1971-05-26
Abstract: 1354358 Triangular wave generators; bistable circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 May 1971 [29 May 1970] 17236/71 Heading H3T A triangular wave is generated by charging a capacitor C in one direction from sources such as T 3  and S 11  until the upper threshold of a bi-stable circuit F is reached whereupon the bi-stable circuit changes over the switches S 1 -S 4  so that charging is reversed until the lower threshold of the bi-stable circuit is reached and the switches thus restored and the cycle restarted. According to the invention the two flanks of the triangular waves are equalized by using the potentials at the plates of the capacitor to control the charge and discharge current. As shown, if the potential at the plates of the capacitor tends to rise the voltage at the junction of R 1  and R 2  will rise and the current through T 3  will be reduced. The bi-stable circuit switches its state at potentials +E and -E appearing at the base of T 5  in the respective states.
