Title: Improvements in Apparatus for Cleaning Sacks.
Inventor: HOLMSTROEM CARL OSKAR RICHARD
Filed: 1908-06-24
Granted: 1909-06-24
Abstract: 13,411. Holmstr÷m, C. O. R. June 24. Cleaning sacks.-Sacks are cleaned internally by means of a frame carrying movable brushes or scrapers. A sack is drawn over the frame from which certain brushes are then caused to protrude, whereupon the sack is moved relatively to the frame. In the construction shown in Fig. 1, the frame 1 carries horizontally slidable brushes 2, 3, 9 provided with springs tending to keep them in the positions shown. When the sack has been drawn over the frame, the brush 9 is worked to and fro by means of the hand-lever 7 and cord 10. The lever is then held depressed so as to force the brushes 2 and 3 outwards while the sack is being removed from the frame. The sack may be reciprocated horizontallv instead of the brush 9. In another arangement, the brushes 2, 3 are actuated by means of bent levers operated by rollers carried by a rod vertically reciprocated by a foot-lever. In a further construction, shown in Fig. 9, the sackcarrying frame 34 is slidable vertically on the frame 1 and is raised and lowered by means of springs 41 and a hand-operated lever 36 pivoted at 37. The lever 36 and therefore the frame 34 may be retained in their lowest positions by a catchlever 44 provided with an arm 45 terminating beneath the foot-lever 30. In using this apparatus, a sack is placed over the frame 34 and retained in position by pins on plates 46 which are adjustably disposed one at each side of the frame. The footlever 30 is then depressed so as to protrude the brushes 2, 3 from the frame 1 and at the same time to operate the catch-lever 44 in order to release the lever 36. The springs 41 thereupon raise the frame 34 and the sack is rubbed against the brushes. A form of scraper suitable for use in place of the brushes 2, 3 comprises a U-shaped blade resiliently attached to the outer edge of a similarly-shaped plate.

Title: Improvements in Apparatus for Wireless Telegraphy.
Filed: 1908-08-05
Granted: 1909-08-05
Abstract: 16,546. Marconi, G., and Marconi's Wireless Telegraph Co. Aug. 5. Wireless telegraphy.-In a duplex system of wireless telegraphy, a gap in the transmitting-circuit is bridged at intervals by projections on a rotating disk, and commutators rotating on the same axis with the disk are arranged to connect the aerial directly to earth when the transmitting-circuit is bridged, and to connect it to earth through a receiving-apparatus at other times. The periods during which the receiving-apparatus is connected to the aerial are much longer than those during which transmission takes place. An additional commutator may be added to short-circuit the receiving-apparatus during the transmitting periods, and separate aerials for transmitting and receiving may be used. The receiving-apparatus is enclosed in a metal casing. By combining the tuning method with this system, multiflex telegraphy may be obtained. In the arrangement shown in Fig. 1, the disks D and commutators C<1>, C<2> rotate on the same axis, and are arranged so that, when the projections S on the disk bridge the gap between the disks SD<1>, SD<2> in the transmitting-circuit, the commutator C' earths the aerial A through the brushes B<2>, B'. During the intervals between transmission, the aerial A is earthed through the receiving-apparatus R, I by the brushes B', B<2> of the commutator C<2>. The synchronous movement of the disk and commutators may be obtained by driving the latter from a synchronous motor supplied from an alternator coupled to the disk. The disks at the two communicating stations are run at slightly different speeds, and it is arranged that more than one discharge is required for a "dot ", to ensure that the receiving-apparatus is not cut off during the whole time of receipt of a signal. Specifications No. 7777, A.D. 1900, No. 21,640, A.D. 1904, and No. 20,119. A.D. 1907, are referred to.

Abstract: 11,067. Watkins, G. St. B. S. May 10. Four-stroke-cycle engines; cylinders, adjusting clearance of; pumps.-A supercompression engine is provided with an adjustable piston K for varying the compression space, and with a rotary fan or blower M for supplying the charge at a pressure of 4 or 5 lb. above atmosphere, when desired. The blower is driven by a friction clutch, which may be allowed to slip more or less, or may be thrown out of action. The blower is provided with a by-pass H<1> and throttle P. When the throttle is in the lower position, not only is the supply from the carburettor throttled, but the blower tends to draw part of the charge back through the by-pass H<1>. The piston K may be fixed to the rod, or it may be free so as not to rotate with it, and a relief valve may be provided to allow compressed gases from behind the piston to pass into the combustion chamber. The blower may be between the carburettor and the inlet valve as shown, or it may force air through the carburettor. For normal running, the piston K and the throttle valve are adjusted simultaneously, so that the compression is constant. At starting, the clearance is increased so as to reduce the compression. For working at loads above the normal, the clearance is increased to its full amount and the blower is brought into maximum action. The clutch lever controlling the blower may be adjusted simultaneously with the piston K and throttle-valve. The distributing-valves are of the type described in Specification 650/09, [Class 7 (vi), Internal-combustion engines, Valves &c. for].

Granted: 1911-06-07
Abstract: 11,336. Heather, H. J. S. May 7. Electrical equipment. - Induction motors for driving winding-machinery, when used as braking- generators excited by continuous current, are provided with an ammeter or equivalent device arranged in the rotor circuit and marked at the current value corresponding to the maximum torque that the generator is capable of absorbing. The ammeter may be furnished with relay contacts for operating a signal when such current value is exceeded ; or the resistance in circuit is automatically altered, or the control gear is automatically locked, so as to prevent the current from exceeding such maximum value. As shown in Fig. 1, the motor 1 is supplied with current from the mains 5 through the reversing-switch 4 and automatic switch 6. When the shunt coil 7 is de-magnetized owing to failure of the main supply, a source of continuous current 9 is switched into the motor circuit. The battery or the like 9 is also connected to the control motor 10, and to an arm 11 which travels over contacts 12. When the current in the motor circuit exceeds ihe value corresponding to maximum torque, the solenoid 14 pulls down the arm 11 to the lowest contact 12, and the motor 10 by means of a worm gear 15, 16 and switch 17 increases the resistance in the circuit. When no current is flowing, the arm reaches the top contact 12, and the motor 10 also rotates to throw in resistance. When a current value between zero and the maximum value passes, the arm is on the middle contact and the motor 10 rotates to cut out resistance. In the arrangement shown in Fig. 2, the resistance switch is operated by the band-lever 20, and, when the maximum current is reached, the arm 11 makes contact at 12 and causes the solenoid 18 to operate the arm 19 to move one member 23 of a ratchet clutch into engagement with the other member 21. The switch then can only be moved in the direct'on to increase the resistance.
