Abstract: 1350323 Delivering sheets WINDMOLLER & HOLSCHER 30 March 1972 [1 April 1971] 15196/72 Heading B8R Sheets 8, Fig. 1, are caused by grippers 5 on chains 4 engaging their leading edges to a position over a receiver comprising an endless band 13 and there released to fall on to the receiver. The trailing end of the first sheet falls on to and is retained by suckers 18 of a suction beam 16, Figs. 1 and 2, further sheets falling on to the first sheet. Each sheet deflects an arm 9 into the path of a light beam of a photo-electric detector 10 controlling a counter which closes a suction valve 21 when a required number of sheets are in the stack, whereupon the band 13 removes the stack. After the deposition of each sheet, a pair of fingers 23, 23<SP>1</SP> held in raised position by pawls are released to move suddenly down on to the trailing end of the sheet by the form of springs 53, 53<SP>1</SP>, the pawls being released in response to the reciprocation of a rod 31 actuated by a cam 35 synchronized with the movement of the grippers 5, the fingers being raised before the deposition of the next sheet by the return stroke of the rod 31. The assembly 16, 18, 23, 23<SP>1</SP>, 31 is longitudinally adjustable along rails 17 according to sheet length. In the case of long sheets carried only by every second gripper, the rod 31 is held stationary by holding the cam follower 40 away from the cam by a pawl 45 actuated by a magnet 44 receiving a control impulse from a cam disc.

Title: Firing-control system
IPC: F41G5/24
Filed: 1970-03-31
Abstract: 1309793 Firing control systems for guns FRANCE ARMED FORCES MINISTER OF 31 March 1970 [31 March 1969] 15276/70 Heading F3C  The invention relates to a firing control system comprising a trainable support, e.g. a turret 17 on which, in use, a gun is mounted. A target sighting means is provided which moves continuously in training with the gun support and a servomechanism means by which through a laying order producing means, the sighting means and hence, in use, the gun can follow a target. The arrangement is such that during the following of the target a value of the angular velocity of the target relative to the gun is derived and multiplied automatically by the time of flight of a projectile to be fired. The correction so produced is then fed to means driving the support in training to produce the angle of lead and an equal and opposite correction is applied to the sighting means whereby the line of sight remains fixed on the target. In the construction shown the layers order producing means comprises a manual control device 1 working through a potentiometer 5, a differential amplifier 6 and a servomotor 7 to introduce into a ball type variable gear 8, 9, 10 a value corresponding to the speed at which the gun support is required to be driven. The output of the gear is evaluated by a difference pick-up 12, an error signal from which indicating the lag of the support with respect to the required position thereof being evaluated thereby. The error signal is passed through an amplifier 14 such that an hydraulic motor 16 is driven to correctly position the support. The angular speed of the target relative to the gun is derived from a potentiometer 5 from whence the value is passed to a circuit in which the aforesaid multiplication is effected. The correction is then fed as a positive quantity to the amplifier 14 and as a negative quantity to servomotor 19 which re-positions the vertical wire 20 of the sighting means. The whole sighting means may however be adjusted. Several methods of producing the error signal for correct alignment of the gun support are disclosed which rely on a member being fixed to the movable gun support and a member fixed relative thereto.

Title: Improvement in process and apparatus for puffing cereals
IPC: A23L1/18
Filed: 1928-05-24
Abstract: 291,036. Ferguson, J. L. May 24,1927, [Convention date]. Roasting granular material; products obtained in special forms.-In puffing cereals the grains are placed in a pear-shaped container 10, mounted for rotation in standards 11 and heated by resistances 20 supplied with current from slip-rings 24. The grains are introduced through a hinged puffer cover 28 which is provided with a valve 15 that in the discharge position of the container can be be coupled to a pipe 17 in communication with a reservoir of high pressure. The cereals are heated, the pressure in the container rising during the process and even heating of the cereals being obtained by rotating the container. Gauges 30 are provided to indicate the conditions obtaining in the container. When the heating process is complete, the container is brought to the position shown in Fig. 1, and coupled to the pressure pipe 17. An outlet valve 14 at the bottom of the container is opened and the grains shot out by the pressure in the container into a receptacle 31, the valve 15 being opened simultaneously with or immediately after the valve 14 so that the pressure in the container as the last grains escape is practically the same as that when the first escape. The connection in the container to the pipe 17 may be so arranged that the pressure derived from the pressure reservoir may be introduced into the chamber through a number of small openings just above the normal level of the grains. The pressure in the container may also be maintained during the discharge by so shaping the outlet opening that the grains plug it until they are all discharged. The container may be heated by other methods such as by gas.

Abstract: 583,387. Liquid-fuel burners. MOTOR PARTS CO. Aug. 14, 1944, No. 15503. Convention date, Aug. 13, 1943. [Class 75 (i)] [Also in Group XXIX] Liquid fuel is supplied through a metering valve 10 to a burner comprising an electric motor 12 mounted on the furnace fire door 16 rotating a shaft 26 on which is mounted a cup 25 carrying fan blades 32 propelling air through the space between outer and inner barrels 15, 41 carried by the door 16 and the annular opening 42 between the barrel 41 and discs 28 carried by the shaft 26. The fuel delivered to the rotating cup 25 is sprayed through nozzles 31 on to the barrel 41 and burns at low settings of the valve 10 in the barrel 41 with air passing through the opening 42. At high settings of the valve 10 combustion takes place in the furnace, the swirling air issuing from between the barrels 15, 41 creating a vortex which causes some of the hot combustion mixture to return along the axis of the barrel 41 and to flow back into the furnace along the barrel surface thereby preheating the fuel issuing from the nozzles 31 and maintaining the barrel 41 at fuel-vaporizing temperature. The air supply to the barrel 15 may be regulated by turning a perforated disc 21 registering with openings 19 in a plate 18 on the door 16. Unburnt fuel drains from the burner through a pipe 35 to a chamber 11 containing a float 43 which when raised operates a lever 46 to release a. weighted lever 52 and thereby close a valve 50 in the fuel supply pipe 38 to the valve 10. The valve 10 may be manually and thermostatically controlled.
