Title: Improvements in or relating to internal combustion engines embodying compression operated fuel injection pumps
IPC: F02M49/02
Filed: 1950-01-11
Abstract: 704,233. Fuel-injection pumps. DOXFORD & SONS, Ltd., W., PURDIE, W. H., and JACKSON, P.Dec. 28, 1950 [Jan. 11, 1950], No. 732/50. Class 102 (1). The piston d of a fuel-injection pump is connected to a piston a subjected, through pipe c, to the pressure in the engine cylinder. The quantity delivered by the pump is controlled by a by-pass valve p connected to the piston a by a lever p<SP>2</SP> so that the valve is open at the beginning of the delivery stroke and the time of closing is varied by adjusting the eccentric p' which forms the fulcrum of the lever p<SP>2</SP>. The outlet of the by-pass valve p is restricted by a spring-loaded ball valve q or a manuallyactuated needle valve which limits the speed of the piston d during by-pass. Injection ceases when the outlet passage m is connected through passage k, grooves e, g and f, in the piston, to the chamber o. The cylinder space l, below the passage m, forms a liquid cushion to bring the piston to rest at the end of its stroke; alternatively, the cushion may be formed by a cylindrical extension of the end of the piston that enters the outlet passage which connects to the end of the cylinder. The upward stroke, under the action of the spring z, is cushioned by a projection r, on the piston a, entering the recess s. The passage c may enter the side of the cylinder and in addition may be spaced from the top so that it is covered by the piston to assist in the cushioning; in this construction the projection r may be omitted.

Title: Improvements in or relating to relay-controlled electrical systems
IPC: H02J13/00
Filed: 1938-01-12
Abstract: 511,187. Electric control systems. CRAWFORD, J., AMES, W. A. B., and LAWLEY, W. E. Jan. 12, 1938, No. 998. [Class 40 (i)] In an electric control system, more particularly for switching on and off street and stairway lighting circuits of a public lighting system, the circuits are selectively controlled singly or in combination by a step-by-step switch which is responsive to impulses of main currents transmitted over a single circuit from a control station. Delay means are also provided whereby a circuit not first in the normal sequence of selection may be completed with completing one' earlier in the sequence. The control impulses may be relayed to operate further step-by-step switches which control additional lighting circuits. Fig. 1 shows a system wherein different sections SP<1>, SP<2> of a lighting system are controlled over a line CL by impulses transmitted by a push button PB. The stairway lights and street lights of each section are operated by relays SR, STR which are selectively controlled by a step-by-step switch MS. The system rearranged for the operation of lighting circuits by switching relays of two types, viz.:- (1) Wherein a relay is held operated by continuous current flow and (2) Wherein a relay is actuated either to its operative or inoperative position by the " make and "break" of circuit. The step-by-step switch MS comprises a number of cams mounted on a common shaft and adapted to be set in any one of ten positions. The cams co-operate respectively with contacts in the switching relay circuits in such a manner that the following switching sequence occurs in response to the second, fourth....tenth impulse -transmitted from the control station:- stairway lights " on," street lights " on," stairway and street lights " on," stairway lights " on," all lights " off." The odd impulses are primarily used for preparing the relays of type (2) for full operation by the following even pulses. A cam is also provided in the step-by-step switch for relaying an impulse at .each step to a subsequent switching point SP<2> over line CL<1> so as to effect thereat simultaneous switching of the lighting circuits. Indicating lamps LP, LS are provided at the control station to signify the effective operative of the last switching point in the chain. The lighting circuits include fuses SF, SF<2>, the fuses SF being adapted to provide an alternative circuit whereby the lighting circuits may be controlled independently of the master switch. The stopping switch is operated by a magnet MC which is conneced through a rectifier to a transformer TP the primary of which is connected between the line CL and the neutral of the supply system which forms the return for the control circuit. A step-by-step indicator MI may be provided at the control station.

Title: Device for quasi-continuous measuring dust content of gases
Inventor: KUTTA JOZSEF
IPC: G01N7/10
Filed: 1987-01-27
Abstract: Equipment is based on a separator unit which creates a pressure drop. The necessary supply pressure is provided by the plant being monitored or by a fan (12). The increase of pressure loss in the separator unit is proportional to the quantity of dust. This proportionality is specific so that the actual process parameters should be kept nearly constant. Equipment is to enable quasi-continuous measurement of dust content, from min. concn. of 0.01 mg/m3 upwards, with dust particles in the region of 0.01-100 microns, such that the results can be checked by gravimetry. The signal produced by the pressure measuring and control unit (7) is calibrated in the first instance by gravimetric evaluation of the filter membrane, which produces the pressure drop. Further measurements are carried out on the basis of the parameters found during the first measurement. The calibration may be repeated at any time, to check the accuracy of the indicated values.
