Title: Improvements in and relating to fuel spraying apparatus for internal combustion engines with airless injection of the fuel
IPC: F02M61/10
Filed: 1929-05-16
Abstract: 331,641. Wilson, D. May 16, 1929. Cam- and spring - actuated pumps; regulating delivery by by-passes and by opening suction valves. - Apparatus for supplying fuel to internal-combustion engines with airless injection comprises a pump plunger C reciprocated in a chamber d<3> by a cam e and surrounded by an annular accumulator plunger D which is moved forward by a spring e<4> arranged between flanges e<3>, d<1> on the two plungers. The chamber d<3> communicates by passages d', a' with a chamber a below the piston I of the injection valve i<1>, and by passages d<4>, d<5>, d<6>, a9, a<10>, as with a chamber above the piston I, so that the piston is balanced until a valve c<3>, c<4>, carried by the plunger C closes the passage d<6> and opens a passage c<6> leading to the inlet passage f<1>. A rise e<6> on the cam imparts a quick movement to the plunger near the end of the stroke. The pressure above the piston I is thereby quickly released, enabling the unbalanced pressure on the lower end to open the valve i<1>. The plunger D, which had been forced back against the spring e<4> by the pressure created in the chamber d' during the forward stroke of the plunger C, is returned by the spring to deliver the fuel through the passage a<7>and valve i<1> to the engine. The amount delivered is regulated by keeping the suction valve F open during a variable portion of the forward stroke of the plunger C by means of mechanism g, g<1>, f<5> operated by the plunger and adjusted by a governor-controlled fulcrum g<8> for the lever g. In another form, the end of the plunger C works in a separate chamber, and during the forward stroke of the plunger the fuel passes from this chamber through passages in the plunger to the chamber d<3>, where it forces back the piston D as before. The delivery is regulated by a by-pass valve connecting the chamber d<3> to the inlet side of the pump and operated by governor-controlled mechanism actuated by the plunger. In 'another form, the delivery is regulated by a peripheral chamber in the plunger D provided with an inclined edge and open to the chamber d<3> through a groove in the plunger. A by-pass port opens into the peripheral chamber, and the plunger D is rotatable to vary the moment in the stroke of the plunger at which the chamber communicates with the by-pass. In another form, the delivery is regulated by an axially adjustable sleeve . surrounding the piston D and provided with a by-pass port opening into a peripheral chamber in the piston. In another form, the end of the plunger D is inclined and the plunger may be rotated to vary the amount of closing of the delivery port.

Filed: 1970-04-01
Abstract: 1308171 Photo-electric chromatograph reader NIHON DENSHI KK 1 April 1970 [1 April 1969] 15539/70 Heading G1A [Also in Division B1] Sequential samples from a chromatographic column 2 are fed to a sample cell 8 and subjected to a photo-electric spectral absorption analysis,  the photo-electric output for the sequence of samples being used to record continuously an absorption spectrum and to plot a chromatogram. For each sample, light from a source 4 is caused by prism 5, mirror 6 and spectroscope (monochromator) 7 to be scanned through a complete spectral range. The detector 10 output is continuously recorded at 12, and is also applied to a gate 13 which is opened at one particular wavelength in the spectral scan as controlled by the spectroscope. The photo-electric signals thereby passed are plotted to form the chromatogram at 14. As an alternative to continuous absorption spectrum recording, the gated photo-electric signals from 13 may be used to obtain a record of peak values of the chromatogram, using shift registers 15, 17 and comparator 16.

Title: An improved pneumatic braking system for electrically driven vehicles
IPC: B60T15/48
Filed: 1935-05-30
Abstract: 441,368. Fluid pressure brakes. EDGE, S. H., and CLAYTON DEWANDRE CO., Ltd., Titanic Works, Lincoln. May 30, 1935, No. 15805. [Class 103 (i)] A pneumatic brake system for electrically driven vehicles comprises a compressor coupled to the vehicle driving motor or to the transmission so as to ensure that any movement of the vehicle automatically operates the compressor, main and auxiliary reservoirs charged by the compressor and means whereby the auxiliary reservoir intercepts the output from the compressor whenever the pressure in that reservoir is below that necessary for operating the brakes. The arrangement may also be such that compressed air may pass freely from the main to the auxiliary reservoir. A similar system may be employed for vacuum brakes. A rotary compressor b coupled to the shaft of the motor a is connected through a valve device c to the auxiliary reservoir d between which and the main reservoir g is a valve device h comprising a diaphragm 3 attached to a valve 1 and subject to the pressure in the reservoir d and to the opposing pressure of an adjustable spring 5, so that only when the pressure in reservoir d is sufficient to overcome the spring is the valve 1 opened to permit air to flow from the reservoir d to reservoir g. When, however, the pressure in reservoir d falls below that in reservoir g the pressures can equalize through a non-return valve 2. When the pressure in reservoir g acting on a diaphragm connected to a valve 8 in the device c reaches the maximum determined by a spring 11, the valve moves over to divert the air from the compressor to atmosphere through a silencer k. The reservoir d is connected to the brake control valve f. An oil separator l for the air delivered by the compressor is provided. A similar arrangement for a vacuum system is also described in which a vacuum pump exhausts reservoirs such as d, g.

Abstract: 1,242,621. Detecting dirt or condensation on windows. ELTRO G.m.b.H. & CO. GES. FUR STRAHLUNGSTECHNIK. March 27, 1969 [March 27, 1968], No.16049/69. Heading G1A. The presence of dirt or condensation on a window 1 is detected by the use of two triangular prisms 2, 3 which are cemented on the inside window surface, a light source 4 and a photo-cell 5. With a clean outer surface light entering the glass of the window is totally internally reflected back and forth along the pane until it can emerge only via prism 3 on the inner surface, and is detected by photo-cell 5. The presence of a drop 7 condensed water on the outer surface allows some light to escape and the photo-cell output is therefore slightly diminished. A decreased output caused by condensation or dirt can be detected and used after amplification, to initiate operation of an alarm lamp or other signalling device or control the starting of, for example, a windscreen wiper or washer.

Filed: 1944-08-28
Abstract: 576,456. Engraving. MILLER, R. S. Aug. 28, 1944, No. 16290. [Class 100 (ii)] To enable work-pieces to be engraved with serial numbers in addition to the pattern, number drums are arranged beneath an opening in the pattern plate. In one form, Fig. 4, each drum 13, freely mounted on the shaft 14 has ten equally spaced pins 18 projecting from one face of the drum, which are engaged by a pawl 23 having a tooth 25 and urged into contact with the two lowermost pins by a spring 26. The pawl is connected to a press-button 20, held in the position shown by a spring 21 and its stroke is just sufficient to turn the drum through a tenth of a revolution. The shaft 14 has ten longitudinal grooves 15 which are engaged by a spring-pressed retaining plunger 16. Instead of the plunger 16, a spring pawl may be used. In a further form, Fig. 7, the units drum only is actuated by a lever 30 which is fixed on a shaft 38. When the lever 30 is depressed it turns, through a dog clutch, the wheel 43; freely mounted on the shaft 28 and having ten notches 44, one of which engages a pin 18 on the units drum 13 and turns it through a tenth of a revolution. Fixed to this wheel 43 is an arm 46 carrying a pin 45 which engages once every complete revolution of the wheel 43, in a notch 47 of a wheel 48 freely mounted on another shaft 49 and moves the wheel 48 through a tenth of a revolution. This wheel 48 is fixed to another wheel 50 having notches 51 engaging the pins 18 of the tens drum 13. The wheel 50 in turn carries an arm 52 with a pin 53 which similarly engages once every complete revolution of the wheel 50 in notches of a wheel 54 freely mounted on the shaft 38 and thus transfers from the tens to the hundreds drum. Similar mechanism provides transfer for the higher denominations. The shafts 38, 49 are mounted in a link 32 pivoted at 35 to the casing 12, and in a similar link, not shown, at the other end. A handle 33 on the link 32 enables the transfer mechanism to be swung out of contact with the drums 13. Instead of being manually operated, the lever 30 may be operated automatically as each new workpiece is placed on the holder.
