Title: Improvements in flush valves
IPC: F16K21/12
Filed: 1940-09-24
Abstract: 544,918. Flushing-valves. MIKALSEN, R. A. Sept. 24, 1940, No. 14516. [Class 135] A flushing valve is actuated by a diaphragm under the control of a tilting disc auxiliary valve seating on the main valve and actuated by a hand lever universally pivoted in a diaphragm. In the form shown in Figs. 1 and 2 a partition in the casing separating the inlet 2 from the outlet 3 has a tubular part 4 formed at its lower end with a seat 47 for a screw-actuated stop valve 43 and at its upper end with a seat 5 for the main valve 6. This valve which is guided by a spindle 23 engaging a spider 231 is clamped to a diaphragm 9 by a hollow pivoted nut 12 which also houses an auxiliary valve 14 controlling a passage 13 connecting the diaphragm chamber 26 with the outlet 3. Inlet pressure is admitted to the diaphragm chamber by ports 19 in the nut and a passage 20 in the main valve member fitted with a throttling screw 221. The auxiliary valve is normally held to its seat by a spring 15 bearing against a cap-nut screwed to the nut 12 and is tilted to initiate the opening of the main valve by the engagement of a cupshaped member 28 with a head 181 on the valve spindle 18. A handle 34 with a collar 421 and screwed tail 35 is screwed into the member 28 so as to clamp a flexible diaphragm 33 backed by a radially slit metal washer 37 between the collar 42<SP>1</SP> and the member 28. The outer periphery of the diaphragm is clamped against a casing shoulder 40 by a hollow nut 38 having a large central aperture to permit the handle to be rocked in any direction to open the auxiliary valve and so cause the main valve to open. In a modification the spindle 23 is made detachable and is bored to communicate with the bleed passage, a throttling screw with a flat along one side being fitted into the end of the spindle 23. In this form the member 28 is replaced by arms engaging the end of the auxiliary valve spindle.

Abstract: 799,555. Road-vehicle spring suspensions. FORD MOTOR CO., Ltd., (Ford Motor Co.). May 11, 1956, No. 14765/56. Class 108(2) A road-vehicle spring suspension comprises an axle 14 carrying road wheels 10, 11, on a common wheel axis O, O<SP>1</SP>, means 21, 22 for constraining the axle 14 to rotation about a deflection axis P, P<SP>1</SP>, parallel to, but below, and to the rear of, the wheel axis O, O<SP>1</SP>, bearing means S fixed to the chassis frame 30 forming a role axis Q, Q<SP>1</SP> and co-operating with connecting means 32 to restrain the axle 14 from vertical or lateral translatory motion, and radius arms 25, 26, pivotally connecting the means 21, 22 to fixed points 27, 28 on the frame 30. As shown, each road wheel 10, 11 is journalled on a respective spindle 13 rigid with the corresponding end of the axle 14. Two pairs of brackets 21, 22 rigid with the axle 14 are pivotally connected to the ends of respective links 25, 26, the other ends of which are journalled on the frame 30 at 27, 28. The means 32 comprises brackets 32, 33 rigid with the axle 14 and journalled at their lower ends on a pin 44, Fig. 3, carried by a bearing block S which itself is pivotally mounted by means of rubber bushings 39, 40 and brackets 41, 42 rigid with the frame 30. Spring suspension is provided by torsion bars 54, 57 connected respectively to opposite ends of the axle 14 by arms 50, 51. A differential gear which also carries the brake drums is mounted on a rubber block carried by a chassis-frame member 67. As shown, the axis Q, Q<SP>1</SP> which is coincident with the axis of the block S and the brackets 41, 42, intersects the axis P, P<SP>1</SP>. The latter lies behind and below the normal position of the axis O, O<SP>1</SP> so that on upward deflection of the road wheels 10, 11, the axis O, O<SP>1</SP> moves upwardly and rearwardly. In the normal position the axis 27, 28 lies below the axis P<SP>1</SP>, S, P. Thus on the occurrence of roll about the axis Q, Q<SP>1</SP>, the link say 26 corresponding to the rising wheel 11 assumes a greater inclination than the link 25, and this results in a forward movement of the wheel 11 relative to the wheel 10 which accentuates the degree of understeer. Modified dispositions of the links 25, 26, the brackets 21, 22, and the brackets 32, 33 are described. In Fig. 10 (not shown) the layout is the same as that described above except that the links 25, 26 extend rearwardly from the axis P, P<SP>1</SP>.

Abstract: 1294396 Sheet forming NRM CORP 31 March 1970 [29 April 1969] 15091/70 Heading B5A In a sheet forming machine, a sheet is indexed by a pair of edge engaging spiked chains 15 through a heating oven 3 and then a thermoforming station 4 at which the sheet is plunger assisted blow/vacuum formed between mould sections 5 and 6 vertically reciprocable by toggle linkages, blowing pressure being applied just before and after mould closure. The chains run between sprockets 16, 17, 18 and 19, sprocket 17 of which is driven intermittently by a clutch 36 itself driven by a chain 39. One end of chain 39 is connected to a crank arm 41 of adjustable length and the other end is connected to an air spring or cylinder 40, the crank arm being driven by a chain 45 itself actuated by an indexing cylinder 47 connected to one end and an air spring 46 connected to the other. In use, when clutch 36 is engaged, cylinder 47 is actuated to rotate the crank arm 41 through 180 degrees clockwise to the position shown in the Figure, thus causing chain 39 to rotate sprocket 17 in an anticlockwise direction and to index the chains and thus the sheets are increment through the machine. After indexing, the clutch is disengaged and the air springs cause the various elements to move back to their previous position ready for the next increment. Located between the chains are support bands to prevent excessive sagging of the sheet. The edges of the sheet run between cooled slide members 11 and are shielded within the oven by suitable masking members (see Fig. 4, not shown). The oven itself includes upper and lower bands of radiant heaters 71 each of which can be withdrawn laterally along rails 70 in the event of overheating.

Abstract: 555,925. Frequency and phase modulation. STANDARD TELEPHONES & CABLES, Ltd. Oct. 30, 1942, No. 15265. Convention date, Nov. 4, 1941. Addition to 551,282. [Class 40 (v)] In a frequency or phase modulation system of the kind referred to in the parent Specification in which short alternate positive and negative pulses are time-modulated in accordance with a signal voltage, the positive and negative pulses are separated and different harmonics of the pulse frequency selected respectively therefrom and are combined in a mixing circuit to give a difference frequency. As shown, a generator 10 is connected through a tuned circuit to a pulse coil 13 which preferably has a laminated permalloy core saturable at a low value of current in the coil. The resulting voltage pulses across the coil are alternately positive and negative and occur substantially at moment of zero current. The signal voltage from a microphone 14 produces a smaller current through the coil 13 which displaces the phase of zero current and gives a phase or time modulation to the pulses. The pulses, which may be sharpened by a circuit 20, 21, are separated by rectifiers 22. 23 and harmonics of different order are selected by filters 24, 25. These harmonics are combined at 26 and the beat or difference frequency is selected by a filter 27. The phase modulation present in the

Title: Improvements in or relating to multi-stage free-piston compressors
IPC: F02B71/04
Filed: 1934-05-22
Abstract: 428,418. Air-compressors. JUNKERS, H., 21, Hauptmann, Loeper Platz, Dessau, Anhalt, Germany. May 22, 1934, No. 15308. Convention date, May 20, 1933. [Class 8 (i)] A multi-stage compressor actuated by an opposed free piston internal - combustion engine, the opposed masses being coupled together for working in unison, is characterized by the disposition of the working diameters of the compressor asymmetrically on the two sides of the engine, the volumetric or pressure ratio of the compression chambers being such that the rate of doing work in the compressor on the working stroke on each side of the engine is substantially the same and the rate of doing work in the compressor to return the moving masses is also substantially the same on each side of the internal-combustion engine. The cylinder 1 of the internal-combustion engine has opposed pistons 2, 3 which are linked by rack gear 12, 12<1> and pinions 13 for working in unison. The pistons are continued and carry compressor pistons 8, 10, 21. The first stage compressor piston has its cylinder portion 9 provided with inlet valves 14 and outlet valves 15. The compressed gas passes through the pipe 16 to the inlet valves 17 of the second stage compressor 11 and is delivered past the outlet valves 18 through pipe 19 to the inlet valves 20 of the high stage compressor 22 and thence by delivery valves 23 to the storage chamber. The inner side of the piston 8 may be used in conjunction with the chamber 30 for supplying scavenging air to the engine. The inner side of the piston 21 may also be similarly used for doing work. When it is necessary to increase the piston area in any one stage to a greater extent than is obtainable by increasing the volumetric ratio, it is necessary in order to prevent absorption of energy rising too high, to arrange for a portion of the indrawn gas to be ejected at the beginning of the working stroke, and this is arranged for by providing delivery valves 24 through which a portion of the gas drawn in through the valve 17 is returned to the receiver 16 at the beginning of the working stroke until the piston 10 has masked the valves 24. Similar discharge valves 25 are provided in the first stage and the air thus discharged is used to supplement the scavenging air.
