Abstract: 696,091. Preparing peat. HESEPER TORFWERK GES. March 7, 1951 [March 20, 1950], No. 5528/51. Class 50 [Also in Group XXX] In a process for airdrying peat previously cut sods are arranged in pairs against one another in the form of an inverted V. The process may be carried out automatically by an apparatus adapted to travel over rows of cut peat sods and having a revolving drum b provided with spikes d<SP>1</SP> or a like pick-up device which picks up pairs of the sods and feeds them to a pair of endless belt conveyers f arranged to twist from a horizontal position near the drum b to a vertical position where the pairs of sods are removed from the conveyers and pass between devices i which press the upper parts of the sods together and deposit them on the ground. The drum b is driven by a motor which also drives the belt conveyers and preferably provides also the means for propelling the apparatus over the rows of peat sods. The rear of the apparatus is provided with slides l. The spikes d<SP>1</SP> are arranged on battens d secured to a flexible belt c and are extended from the circumference of the drum b by a cam disc when they reach their lowermost position to pick up the sods and eventually to transfer them to the conveyers f when the spikes are retracted. The conveyers f may have spikes g to grip the sods and also to indent their surfaces to enable the sods, when dry, to be easily broken up into smaller pieces. The devices i may consist of rakes and further pressure may be applied to the upper portions of the sods by pairs of belts or rollers n. The conveyers f may be driven at the same or at different speeds, the sods of each pair of sods in the latter case being arranged in an off-set position.

Title: Improvements in control devices for centrifugal extractors
IPC: B04B7/06
Filed: 1929-02-20
Abstract: 306,545. Krantz, H. [Firm of]. Feb. 24, 1928, [Convention date]. Driving; casings.-Controlling means for a centrifugal extractor comprises a timing mechanism for releasing a latch after a pre-determined length of operation of the extractor; the release of the latch permits the stopping devices to operate and allows the timing mechanism to move into the starting position. A bracket b secured to the extractor casing a carries a sliding bolt 3 provided with a rack 3'. The hand lever 1 carries a pinion 2 engaging the rack, and is also connected by a link 7 to a bell-crank lever 8. One arm of the bell-crank is connected to the belt-shifting mechanism 10, and another arm is connected to the lever 14 of the band brake 15 of the extractor basket c. The upper end of the bolt 3 is notched to receive the projection 4<1> of the latch 4, and the end 4" of the latch is in a position where it can engage a cam 18 on the timing disc 16 driven from the extractor spindle. When the extractor is at rest the parts are in the position in Fig 3. Closing the cover of the extractor withdraws the locking pin 21 from the bolt 3 and the handle 1 is then depressed. This releases the brake and also moves the driving belt from the loose pulley 11 to the fast pulley 12 to start the machine. The bolt 3 is also raised against the action of the spring 6, and is held raised by the latch 4. The extractor rotates the disc 16 until the cam 18 reaches the latch when the latter is tripped and the bolt 3 is released. The spring 6 pulls the bolt down to throw the belt to the loose pulley, and to put on the brake. The machine stops with the cam in the position shown in Fig 3 with the apparatus ready for re-starting. If a period of travel is desired shorter than that fixed by one revolution of the disc 16, additional cams may be attached to the disc. A pin 26 is provided to hold the bolt in a position where the brake is released to enable the basket to be rotated by hand.

Filed: 1921-02-19
Abstract: 180,068. Evans, L. T. Godfrey-. Feb. 19, 1921. Valves; talve-gear; regulating.-Engines having two or more cylinders, in each of which work two oppositely-moving pistons 47, 49 with combustion chambers 37, 36 formed between the pistons and above the upper pistons, have a single air pump 32 placed above the working cylinders. The scavenging-air passes through the pump outlet valve 33 into the passage 34 and through piston-controlled ports 48 to the combustion chambers Compressed air also passes through the pump outlet valve 35 to the carburettor, the rich mixture entering the tubular slide valve 38, which is placed between and serves two cylinders and is cam-actuated. This valve has three ports 48<1> which register with cylinder ports 39, the pistons also overrunning these ports. The exhaust from the central chambers is led to the closed crank chambers, where, after further expansion, it is finally exhausted through one or more cam-actuated valves 44; or these valves may be worked by the means described with reference to Fig. 4 of Specification 30368/09. Fuel is supplied to the carburettor from a tank 1 by the pressure of the gases in one of the combustion chambers, the amount of fuel supplied being dependent on the gas pressure and therefore varying with the working of the engine. The air pump comprises a perforated piston 32<1>, below which lies a perforated plate 32<IV>; on the up-stroke air passes through these perforations to the lower side of the plate, the piston and plate moving together and closing the perforations on the down or compressing stroke. Air is admitted to the upper chamber of the pump through a disc valve which is given a step-by-step movement by a pawl and ratchet; the ratchet is oscillated by a pin and groove device on a tail rod of the pump piston; or the valve is moved through a pin and endless-groove device. The pump may be double-acting. Specification 7101/11 also is referred to.
