Title: Improvements in or relating to method and machine for manufacturing pellets
IPC: B30B11/14
Filed: 1966-04-29
Abstract: 1,144,261. Moulding pellets. CHAMBON Ltd. 29 April, 1966 [6 May, 1965], No. 18947/66. Heading B5A. In a method of moulding pellets a procession of moulds 1, Fig. la, each having one or more cavities, are moved in abutting relationship through a charging station, a compacting station, a separating station and a discharging station. The charging station comprises a hopper 6 in which spider wheels 7, 8 and 9 are located, and the aligned cavities of the abutting moulds are filled to a level determined by the adjustable gate 12 so that a continuous strip or strips are formed. The compacting station includes a ramming head 13 reciprocated by an eccentric mechanism 14, 15. At the separating station trunnions 2 and 3 which extend from opposite ends of the moulds ride along cams 17, 17a, Fig. 4, and the moulds are thereby moved transversely, adjacent moulds being moved in opposite directions so as to divide the strips into lengths. The moulds are again aligned and spaced apart before a pusher member 19 dis charges the separate lengths forming the pellets on to an inclined guide which leads to a conveyer belt.

Title: Improved valve
IPC: F16K1/48
Filed: 1950-07-31
Abstract: 682,026. Manually and mechanically actuated valves. WINFREE, R. W. July 31, 1950, No. 19018/50. Class 135. In a valve which includes a closure member movable under manual control towards and away from its seat, a device in the valve housing comes into action when the closure member has been manually approached to a predetermined distance from its seat and releases the closure member from manual control so that it continues its closing movement under the control of a resilient member. In an embodiment, the valve 21, Fig. 1, is urged by a spring 18 towards the closed position. The upper end of the stem of the valve is provided with a stepped surface 28 which, when the valve is open, is forced by the spring 18 into engagement with a similar stepped surface 30 carried by a rotary screwed cap 8. Keys 15 formed on the upper part of the valve stem engage in corresponding grooves in the valve casing and allow the stem to execute only a longitudinal movement. As the cap 8 is rotated in the direction to permit the valve to close, the stepped surfaces 28, 30 will first be in sliding and abutting relation but, when the surface 30 slides off the surface 28, the connection between the two parts of the stem will be broken and the valve will be projected by spring 18 into the closed position. In another embodiment, the two parts of the valve stem 53, 70, Fig. 8, are connected by a swivel pin 56 which allows a small amount of lost motion between them. The lower part 70 carries a rigid projection 69 which, as the valve approaches the closed position, engages a spring-loaded projection 66 in a casing fixed in position in the valve housing. The friction between the two projections is sufficient to arrest the movement of the part 70 until the lost-motion between the two parts of the stem has been taken up. Projection 69 will then be forced past projection 66 and the valve loading spring will complete the movement of the valve to the closed position. In a modification, the two projections are replaced by a pivoted latch which momentarily disconnects the manual drive and allows the valve loading spring to act.

Title: Improvements in hydraulic brakes
IPC: B60P1/02
Filed: 1932-07-11
Abstract: 385,884. Dashpots. STEINBOCK AKT.-GES., Moosburg, Upper Bavaria, Germany. July 11, 1932, No. 19572. Convention date, Aug. 11, 1931. [Class 108 (iii).] A hydraulic brake for lifting-trucks comprises a cylinder and a piston having a port controlled by a piston valve slidable in the piston, which valve is actuated by the pressure of the brake fluid so that with increasing load increasing restriction is imposed on the flow of fluid through the port during the descent of the load. The cylinder 1 is fixed by means of a lug 12 to the driving frame and the pistonrod 6 by an eye 13 to the lifting frame of the truck. In the piston 2 slides a pin valve 10 fixed to a piston 9 sliding in a hollow part 14 of the piston-rod and having a spring 8 bearing thereon. When the lifting-truck is raised the piston 2 is drawn out, the spring 7 compressed, and the brake fluid passes from one side of the piston to the other through holes 15 in the hollow part 14 of the piston-rod, a bore in the piston 9, a tapered groove 21 in the pin valve 10 and a bore 11 in the piston 2. When the lowering is started the load presses on the piston and thereby on the fluid to the left of the piston which pushes the pin 10 into the piston against the spring 8 in proportion to the load, thereby diminishing the cross section of the passage through the piston by means of the tapered groove 11. The tapered groove may be replaced by circumferential grooves on the pin 10 of increasing width or holes of increasing diameter or an increasing number of holes. In a further construction a conical part of the pin 10 controls a passage passing across the piston and connected by passages to each end of the piston. In a further construction, Fig. 6, the pin 10 passes through a tapered chamber in the piston 2 connected by passage 11<1> to the right-hand end of the piston and a hollow part of the pin leads from this chamber to the left-hand end of the piston.

Title: Digital transmission systems
IPC: H04B17/40
Filed: 1972-04-27
Abstract: 1420078 Digital data transmission; fault detecting GENERAL ELECTRIC CO Ltd 7 March 1973 [27 April 1972] 19660/72 Heading H4P A data transmission system comprises a series of error monitoring circuits positioned along a transmission path, each monitor being operable to detect errors in the transmitted signal and to send information regarding the errors to a control terminal which selects each monitor in turn by a command signal which causes the monitor currently selected to send a second command signal to the next adjacent monitor. The system utilizes a code in which three signal levels + 1, 0, - 1 are used, each group of four binary digits being coded into a group of three level digits. In addition, the codes are so constructed that strings of zeros and signals of like polarity are limited in length, and monitoring equipment associated with each regenerator in the transmission path indicates if a string greater than the permitted length occurs. Each monitor comprises a pair of trigger circuits, responsive to the + 1 and - 1 signals respectively and an integrator which is reset by these signals. The outputs from the two triggers are arranged to step a forward/backward counter, which produces an output if more than a predetermined number of consecutive pulses of one polarity occur. The integrator similarly produces an output if too many zeros occur. The integrator and counter outputs are fed to a monostable circuit which produces an output signal having a mark/space ratio dependent on the rate of fault occurrence. In order to set the first monitor into operation, the transmitting station transmits a continuous tone B and a short burst of a different tone A. When tone A ceases the monitor sends a " monitor held" tone C back to the transmitting station and, after a delay, transmits the output from the monostable. When it is desired the tone B is interrupted to cause the first monitor to turn off, and to transmit an A tone to the next monitor. Reinstatement of the B tone then turns on the next monitor in a similar manner. Selection of a particular monitor may be achieved by stepping on as soon as a C tone is received. This is done by counting the number of C tones received and comparing the count with a predetermined count.

A mould for a cast iron pipe or other elongated article is made by filling with uncompacted sand, a flask of such a size that when the sand is correctly compacted to form an axial hole this has the diameter required, then centrifuging to densify the sand against the flask, and then compacting further. The filled flask is rotated about its axis to compact the sand sufficiently to allow a mandrel to be introduced axially which may be done after turning the flask from vertical .to horizontal position. The flask is then rotated and the mandrel moved against the sand wall to compact it and produce a hole of the desired diameter. The internal diameter a of flask required to cast a body having external diameter b may be obtained from the equation a<2>= S<1>/S (a<2> - b<2>), where S<1>/S is the ratio of the specific gravity of the compacted to that of the uncompacted sand. If this ratio is taken as 1.4 the equation becomes a=#3.5b<2>. The desired inner diameter of flask may be obtained by using an insert in a larger flask. The flask may be carried by a moulding and centrifugal-casting machine of the kind described in Specification 650,683.
