Title: Two-stroke internal combustion engines
IPC: F01L1/00
Filed: 1954-11-05
Abstract: 747,087. Valves and valve-gear. SULZER FRERES SOC. ANON. Nov. 5, 1954 [Nov. 6, 1953], No. 32159/54. Class 7(6) [Also in Groups XXVI and XXIX] An oscillating exhaust valve 14, Fig. 2, in series with a piston-controlled exhaust port 15 of a two-stroke engine cylinder 2 is engine-driven via a hydraulic system 17, 18, Fig. 3, provided with relief valves 22, 23. A receiver vane 26 on the valve spindle is oscillated from a transmitter piston 25 of greater displacement reciprocated by a crank-shaft 11 gear-driven from the engine crank-shaft, the liquid in excess at each stroke being discharged to a pipe 32 via the valves 22, 23 and an orifice 31 in a spring- loaded piston 30. Excessive system pressure, as due to fouling of the valve 14, is arranged after one, or more or less than one. stroke to drive back the piston 30, which action uncovers the pipe 32 and shuts off the engine fuel supply also. Supply valves 20, 21 keep the system 17, 18 full of liquid, and there is a short-circuit valve 24. In Fig. 4, in which supply valves 20, 21 and relief valves 22, 23, again discharging to engine stop-gear means, are positioned as shown, the receiver vane 26 is. driven by a transmitter vane 39 oscillated by a beam 35 interconnecting engine and scavenge pump pistons 3, 36, the large difference in displacement of the vanes 26, 39 being used in conjunction with a by-pass 41 to provide a phase difference between the valve 14 and piston 3. The vane 39 may be oscillated by an articulated pipe supplying to an engine crosshead oil used also as the hydraulic liquid. Reference is made to a transmitter piston driven from the engine piston, crosshead or connecting rod.

Title: Hydraulically operated drop-hammer
Inventor: BRAUER WILLI
IPC: B21J7/36
Filed: 1960-09-20
Abstract: 930,423. Hydraulic drop hammers. LANGENSTEIN & SCHEMANN A.G. Sept. 20, 1960, No. 32238/60. Class 83 (4). In an hydraulic drop hammer whose tup 4 is raised by pressure liquid admitted below a piston 2 in a cylinder 1 under the control of a valve 18 and is caused to fall by opening an exhaust valve 11, the opening of valve 18 which determines the height to which the tup is raised, is controlled through a time-delay system. The hydraulic system is of the kind described in Specification 920,099 but the tup height is selected by a switch 63 which puts into circuit one or other of time-delay devices 64 controlling the solenoid actuated relay valve 28. The delay period is started when pressure builds up in chamber 9 to effect the upstroke; this pressure acts through pipe 50 on pressure switch 52 in series with the time-delay devices. The latter may be operated electrically or by clockwork mechanism and are infinitely variable. Alternatively, the delay period may be started in dependence upon the impact of the hammer head on the workpiece. In another embodiment, Fig. 2 (not shown), the hammer also incorporates the height control system of Specification 920,099 which may be selected as an alternative to the time delay. Specification 721,335 also is referred to.

Title: Process and apparatus for the recovery of oils, bituminous matter, tar, and resin from bituminous shale, oil-bearing sands, bleaching earths, peat, brown coal, coal and wood
IPC: C10G1/02
Filed: 1921-12-02
Abstract: 198,705. Plauson's (Parent Co.), Ltd., (Plauson, H.). Dec. 2, 1921. Mineral oils, extracting and purifying.- Oils, bitumens and resins are obtained from shale, oil-bearing sands, bleaching earths, peat, lignite, coal, or wood, by effecting distillation of the materials in a current of steam or inert gas, such as carbon dioxide, moving at a high velocity of the order of 100 meters per second and upwards. The temperature is below the ordinary temperature of decomposition of the materials. A small quantity of solvent such as benzine, benzol &c. may be added to the steam or inert gas. The material, for example oil shale, may be passed down a vertical cylinder H, Fig. 1, from a feed device C to a discharge-worm G. Steam, which may be superheated to about 350‹ C. and under a pressure of 3-5 atmospheres, is fed through a ring-shaped device having nozzles F such as are used in steam turbines, and expands to form a stream moving at about 500 metres per second. Steam and entrained matters pass away through slits K protected by wire netting. The lower part of the cylinder H is surrounded by a cooling- jacket in which water is preheated for use as boiler feed. A horizontal cylinder through which the material is fed by a worm, may be used. Steam is supplied through a single nozzle near the outlet, and passes with the material from the outlet. In a complete installation shown in Fig. 3, steam, generated in a boiler 1 under a pressure of 15-20 atmospheres, is passed through a superheater 3 to an engine A from which it passes by a pipe 9 at a pressure of about 10 atmospheres. The steam is heated in a superheater 10 to 400- 500‹ C. and is expanded in a nozzle 11 to form a stream of high velocity which passes downwards through the shale &c. in a cylinder 13. Part of the oil separates in a space 14 and passes through a cooling-coil 16 to a collecting vessel 18. The steam and remaining vapours pass to a separator 21 through a nozzle 20 which causes a rotary motion of the gases, and to which reagents, for example a solution of a lead salt to remove sulphuretted hydrogen, may be supplied by a pipe 31. The oil &c. passes through a cooling-coil 16a to a vessel 18<a>. The steam passes by a pipe 23 and superheater 24 to a compressor B and thence again to the engine A. Bituminous coal yields a product containing montan wax and a petroleum jelly. In treating peat at 375-400‹ C., tar, oils, wax, methyl alcohol, acetic acid and acetone are obtained. In treating roots and resinous woods under vacuum at about 220‹ C. turpentine, resin, and a small amount of resin oil are obtained. The wood may be afterwards treated with steam at about 300-380‹ C. to yield methyl alcohol, acetic acid, acetone and tar oils.

Abstract: 1452024 Electric selective signalling COLUMBIA SCIENTIFIC INDUSTRIES CORP 26 July 1974 [30 July 1973] 33178/74 Heading G4H The invention relates to a control device for programmed electric control of remotely located apparatus (e.g. audio visual equipment) using a plurality of audiotone channels. The device operates in both RECORD (REC) and PLAYBACK (PB) modes, determined by the setting of switches at various points of the network. In the PB mode, tone signals from, e.g., a tape recorder 14 are applied via a sensitivity control 16 and an input amplifier 12 to frequency detection channels 10, the frequencies 20 being octavely related so as to avoid false triggering by unwanted harmonics. Recognition of an incoming tone causes circuitry in the appropriate channel to transmit a signal to a detector 30 which converts it to D.C. and compares it with a reference voltage; if the incoming signal exceeds the threshold, then an output driver circuit 32 (containing an SCR and Zener diodes to remove the effects of transients) is actuated. The REC mode is selected by means of switches located in the various components of Fig. 1 and by means of a switch 28 which allows frequencies generated by selected circuit 18-22 (now acting as a plurality of oscillators) to pass via an output amp 34 to a meter M-1 and to recorder 14 (via jack plug J-2). Detailed circuit embodiments for the components of Fig. 1 are described with reference to Figs. 2-5 (not shown).
Patent GB-332347-A (GB)
Abstract: 332,347. Zimmermann, G. June 4, 1929. Moulding-machines of the turnover type have means for jarring as well as pressing the mould. The pattern 18, Fig. 3, and flask 19 are placed on a table 5 which can be jarred by a plunger 36 which is reciprocated in its cylinder 4 by compressed air or other fluid supplied through a jarring valve 15 and contol cock 12, Fig. 2. The cylinder 4 is mounted in a plunger 3 which can be raised in its cylinder 2, by compressed air &c. admitted by a pipe 11 and a control cock, to press the mould against a plate 20 which is connected by a rod 24 Fig. 3, to a piston 22 which can slide in a cylinder 21 mounted to swivel on the turnover frame 1 which carries the cylinder 2. During pressing the plate 20 is held by its rod 23, engaging a pivoted abutment 29 but during drawing, after inversion, the abutment is withdrawn, against the action of a spring 31, Fig. 2, by a lever 30 and the roller end 25 of the rod 23 is gradually lowered by a cam face on the abutment 29 until this is entirely removed. The movement is however controlled by regulation of a cock which only allows the air below the piston to escape slowly. Instead of using the cock, air at any desired pressure as controlled by the regulator 37 may be maintained below the piston 22 by a cock 40 which is opened when the lever 30 is operated. When the frame 1 is returned the plate 20 &c. fall to the original position and the lever 30 &c. are returned by the spring 31. If it is desired to lift the plate 20 when in the upright position air may be admitted below the piston by a cock 34. Fabric hose 27 prevents dust from entering the cylinder 21. If desired a single cylinder may be used for both jarring a,nd pressing.
