Patent GB-1303931-A (GB)
IPC: F02P5/10
Filed: 1971-05-25
Abstract: 1303931 Timing ignition FORD MOTOR CO Ltd 25 May 1971 [30 July 1970] 16828/71 Heading F1B A spark timing control system comprises an engine carburetter 10 having an induction passage 18 containing a spark port 28 located above the idle speed position of a throttle valve 26 controlling flow through the passage and subject to the change in pressure level in the carburetter as a function of the movement of the throttle valve from its idle speed position, an engine distributor having a breaker plate 12 pivotally movable in opposite directions to advance and retard the spark timing, vacuum controlled servo means 14 connected to the breaker plate for moving the same, conduit means connecting the spark port and servo means and slow-fast flow rate control means in the conduit means to control the rate of change of application of vacuum from the spark port to the servo means. The control means includes faster flow rate means 54, 58 operable in response to a change in the vacuum at the spark port to a lesser depression than at the servo means to quickly equalize the pressure level at the servo means to that at the spark port and slower flow rate means 56, 62, 68 in a fluid flow circuit by-passing the faster flow rate means. The slower flow rate means includes a fluid reservoir 62 open at one end to the spark port and open at its opposite end to the distributor servo means and containing a pair of flow restricting means 68, 82 one adjacent each end, the flow restricting means 82 adjacent the spark port end of the reservoir being unidirectional with respect to flow. The flow restricting means 82 is operable in response to a change in the depression at the spark port to a greater depression than at the servo means permitting flow through the unidirectional means to delay the equalization of the pressure level at the servo means to that at the spark port to delay the spark timing change. The depression in the reservoir decays slowly by flow through the faster flow rate means 54, 58 and the flow restricting means 68 adjacent the servo end of the reservoir in response to a reduction in the depression at the spark port so that the spark timing setting is more rapidly advanced upon reacceleration following a momentary deceleration than upon initial acceleration or upon acceleration following an extended period of deceleration.

Title: Improvements in devices for hot spraying of materials
IPC: B05B7/32
Filed: 1954-06-09
Abstract: 740,135. Compressed-air engines; valvegear. AKTIEBOLAGET ATLAS DIESEL. June 9, 1954 [June 29, 1953], No. 16894/54. Classes 122(2) and 122(3) [Also in Group XXIX] A pneumatically operated engine, Fig. 2, for pumping hot liquid to a jacket of a hose line supplying spray material' to a spray gun (see Group XXIX), includes a cylinder 13, a piston 29, a liquid inlet 14 to the cylinder controlled by a suction valve 30, and a outlet 15 controlled by a ball valve 31. The piston rod carries an auxiliary piston 33 in an auxiliary cylinder and a valve throwing member 34, and compressed air is constantly supplied to the auxiliary cylinder through a conduit 41. Compressed air is also fed via conduits 22 and 43 to a valve housing 23 controlling the operation of the engine, and is supplied via conduits 22 and 27 to the upper side of the engine piston when a valve 24 is opened. This valve is opened only when a sleeve 25 is shifted by a membrane 37 from the position shown to a lower position. The sleeve is held in either of its positions by a spring-pressed ball 26. When the piston has reached its lowermost position, as shown, the member 34 opens a valve 35 causing the membrane to move upwards, and the upper end of the engine cylinder is vented through a passage 51, and the auxiliary piston moves the main piston upwardly. In the upper position a valve 46 is opened by the member 34 and the valve 24 is opened to cause the downward movement of the engine piston. In a modification, Fig. 3, the valve arrange ment for controlling the engine operation is mounted within the auxiliary piston 33, and a passage 54 in the piston rod leads to the upper part of the engine cylinder 13. Theauxiliary cylinder is closed at its upper end by a plug 56 and has a vent 57. In the position shown compressed air from an inlet 41 passes through passages 69, 71, 75, and 54 to the upper side of the piston 29 and moves it downwardly until a pin 63 strikes the bottom of the auxiliary cylinder. A valve 61 is opened thereby, and compressed air flows to a chamber 66 which moves a piston 67 to the right and a valve 73 is opened thus causing the upper end of the main cylinder to be vented through passages 54, 75, 71, 76 and the vent 57. The piston 33 is then moved upwardly until a valve 60 is opened by the plug 56 and the chamber 66 is vented. The piston 67 is thereby moved to the left and closes the valve 73 and compressed air is again supplied to the upper side of the piston 29.

Filed: 1934-06-11
Abstract: 427,233. Distilling metals. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. June 11, 1934, No. 17273. Convention date, July 29, 1933. [Class 82 (i)] A rotary condenser 1 for the fractional condensation of metal vapours is divided into compartments A, B, C, by damming rings 5, 6, the metal baths 7, 8 and 9 formed being completely separated from each other. The vapours enter at 3 and the residual gases leave at 4. In the wall 2 of the condenser 1 are provided devices 13, 14, 15 so that the temperatures of the compartments A, B, C, may be adjusted to the temperatures required. The devices 13, 14, 15 may be constituted as cooling pipes or as electric heating devices. Instead of cooling pipes 13, 14, 15 the outer jacket of the condenser may be cooled to different temperatures. For example in the condensation of zinc vapours, containing lead and cadmium, and flue dust the temperature in the chamber A is maintained at about 900-950‹ C., and the greater part of the lead with a proportion of zinc is condensed therein. The gases then enter chamber B in which the temperature is maintained at about 600‹ C. and here the main portion of the zinc is condensed, the cadmium with a small quantity of zinc being deposited in the form of a cadmium-zinc alloy in chamber C. Apertures 10, 11, 12 are provided in the compartments for drawing-off the metals therein. To assist in the condensation filling bodies, e.g. iron rings, or short pieces of tubes may be placed in the chambers and if the temperatures in the chambers are not sufficiently low, solid or liquid metal may be supplied to the chambers, e.g. liquid metal may be supplied from a trough 17 by a conveying device 18 to a spiral pipe 19 or solid or liquid metal may be fed in through the openings 3 or 4. The inner walls of the condenser may be provided with blades or projections 20. The apparatus may also be used for the condensation of vapours of arsenic, antimony, magnesium aluminium, lead and silver.
