Title: Methods and means for reducing the emission of pollution products by internal combustion engines provided with carburation means, during deceleration periods
Inventor: BAUDRY JEAN
IPC: F02M35/00
Filed: 1969-12-18
Abstract: 1293772 Spray carburetters; extra air valves INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 18 Dec 1969 [24 Dec 1968] 61742/69 Heading F1B In an I.C. engine having at least one cylinder and having a carburetter in which the throttle valve 5, Fig.1, closes the induction passage 1 completely during idling, the idling mixture being supplied to the engine through a by-pass passage 12, means are provided for reducing the emission of noxious constituents in the engine exhaust gases during engine deceleration with the throttle valve closed and the engine speed above a predetermined value, e.g. 800 r.p.m. The means, which may also be responsive to conditions of the clutch or gear-box of an associated vehicle comprises a valve 17 which during such decelerations closes the idling passage 12 and opens a passage 20 to allow the engine cylinder to receive air via an orifice (22), Figs.1A, 1B, 1C (not shown), positioned immediately upstream of the cylinder inlet valve. The valve 17 is moved to the position shown by an electrical coil 19 which is energized by a battery (24), Fig.2 (not shown), when a pair of series connected switches (i) and (R) are closed. The switch (i) is closed when the throttle valve 5 is closed, by a cam (29), Figs.3A, 3B (not shown), incorporated in the throttle valve actuating linkage. The switch (R) is closed when the voltage between the terminals of a dynamo (D) exceeds a predetermined value, or when the output voltage of a tachometric device (T), Fig. 5 (not shown), exceeds a predetermined value, the device (T) being connected with the contact breaker (A) of the engine ignition circuit so that its output voltage varies as a function of the breaking frequency of the contact breaker. Moreover, the primary winding (34) of the ignition coil can be isolated by a switch (37) operated electrically by a coil (38) connected in series with the switches (i and R) so that the engine ignition is switched off during the engine decelerations. The throttle valve actuating linkage incorporates a pin-and-slot lost-motion device (30, 31) whereby the valve 17 is caused to open momentarily before the throttle valve, and vice versa in the closing direction. The valve 17 may incorporate means for pre-setting the idling flow-rate, Fig.4 (not shown).

Title: Float type steam trap
IPC: F16T1/38
Filed: 1978-06-20
Abstract: The invention provides an improved steam trap of the kind having a spherical float 50 which is freely accommodated within a condensate-collecting sump 30 and cooperates directly with a valve seat 92 surrounding an outlet port 106 to control the discharge of condensate from the sump through this outlet port in dependence upon the level of condensate in the sump. In order to prevent violent impact of the float against the valve seat at the end each closing movement of the float and consequent risk of damage to the latter, without at the same time unduly reducing the rate of discharge of condensate when the float is unseated, there is provided, in the flowpath of the condensate on the downstream side of the outlet port, an orifice 112 having a flow area 0.5 to 1.0 times as large as that of the outlet port 106. <IMAGE>

Title: Drop back catch assembly
IPC: B66B5/08
Filed: 1979-06-11
Abstract: A drop back catch assembly for a vertical lift cage (7) or similar conveyance reduces the weight normally carried by the cage by coming into operation only when the cage travels above the upper limit of normal travel. A rack (11) having opposed sets of teeth is disposed adjacent the overrun path of the cage, mounted on a rack post (3) itself mounted to thrust back beams (4) which extend horizontally across the lift shaft. A catchblock assembly (1) has rollers (12) and travels in roller channels (13) carried by supports (14) mounted on the thrust back beams. A double set of pawls (8) engages with the opposed teeth of the rack 11 allowing only upward movement of the catchblock assembly with respect to the rack. A lip (15) and ledge (16) extending from the catch block engage with an engagement catch (17) on the cage only when the cage travels above a predetermined position, whereupon the cage carries the catchblock, and the rack and pawls provide a drop back catch action preventing the cage from falling. The catchblock and cage are thus interengaged only in the event of drop back protection being required. The ledge (16) may be on a pivoted latching hook (18a). <IMAGE>

Title: Thermally sensitive control valve
IPC: G05D23/02
Filed: 1981-01-16
Abstract: A thermostat valve has a thermally sensitive bulb 17 mounted to move axially within a frame 10 having a stationary seat 14. A movable valve element 27 has sliding contact with the seat 14.
