Title: Improvements in or relating to high frequency electron discharge tube structures
IPC: H01J23/16
Filed: 1943-08-20
Abstract: 632,924. Velocity-modulation tubes. SPERRY GYROSCOPE CO., Inc. Aug. 20, 1943, No. 4796/46. Convention date, Aug. 3, 1942. Divided out of 632,913. [Class 39 (i)] Velocity-modulation apparatus includes a pair of hollow resonators through which an electron beam passes in succession, grid means being provided between the resonators to reduce coupling therebetween. As shown, an electron beam from a cathode 1 passes through resonators 3 and 4 coupled by loop 24 and then to resonator 5. A grid 35 is interposed between resonators 4 and 5 to reduce the coupling. The oscillations are set up by the co-operation of resonators 3 and 4 but the latter only absorbs enough energy for this purpose, the remainder being carried to resonator 5 which extracts the energy from the beam. Energy is led from resonator 5 by a coaxial line 25. The other resonators may also be provided with coaxial line outlets. The grid 35 and the adjoining exit and entrance grids 18 and 22 may be combined in one elongated structure. This may be formed of a tube with radially extending conducting fins extended along its interior length. Specification 632,913 is referred to.

Abstract: 233,086. Dawson, Payne, & Elliott, Ltd., Stott, E., and Payne, C. Feb. 28, 1924. Gripper mechanism.-A single or two-revolution printing-machine of the kind in which the impression cylinder a is fitted with turn-over grippers b which are normally closed against spring action for part of a revolution only by means such as a pinion c and an oscillating sector e controlled by a cam h, is constructed with means for preventing the normal opening of the grippers when it is desired to carry the sheet through more. than a single revolution. The closing of the grippers is prevented, when the bowl g of sector e moves off the raised part h<1> of the cam h, by means of a plunger p which is brought into the path of an arm r on the shaft c by mechanism operated by a toothed rack i mounted so as to slide in the axle k of the cylinder a. The rack i is operated, when desired, by a lever and cam, and the rack i is thus moved against the action of a spring which returns the rack when the cam permits. The rack i engages a pinion o meshing with a rack on the plunger p, and moves the plunger into the path of the arm r when the opening of the grippers is to he delayed.

Abstract: 901,237. Delivering measured quantities of powder. WARRINGER, F. A. May 10, 1961 [Feb. 13, 1961], No. 5220/61. Class 106 (5). A device for dispensing a controlled amount of soap or other powder from a container 5 comprises a member forming or adapted to form part of a wall 1 of the container and having an opening 2 for the passage of powder from the container, a resiliently-urged slide 9 for controlling the passage of powder through the opening, a pivotally-mounted shoot 16 movable from a non-dispensing position in which it receives powder to a dispensing position in which the powder is discharged, and co-operating means 11, 19 on the slide and shoot such that, when the slide is moved against the action of the resilient means to uncover the opening, the shoot is secured in the non-dispensing position and, when the slide is released and moves to cover the opening, the shoot is released for movement to the dispensing position. The dispensing member has side walls 4 and top wall 3 for fitting over an upper corner of the container, and has a hook 7 for engaging over the lower edge of an opening 6 in the container, this opening 6 registering with the opening 2 in the member. The front wall 1 of the member has flanges 8 providing channels for receiving the slide. A dispensing operation is carried out by pulling the slide 9 downwardly by a handle 10 and tilting the container so that powder passes through the openings 2, 6 into the shoot which at this time is locked in closed position by a hook 11 at each side of the slide engaging with a corresponding flange 19 on the shoot 16. This is followed by releasing the slide which then returns to close the openings 2, 6 and release the shoot for swinging movement under gravity to discharge the powder. The dispensing member may be made of plastics material and if desired, may be fitted to a lower corner of the container instead of as described above. The front wall 1 of the member may be constituted by a wall of the container itself.

Title: Pipe flaring tool
Inventor: TEMPLE ROBERT
IPC: B21D41/02
Filed: 1962-02-12
Abstract: 928,070. Stamping; pipe flaring. MINE SAFETY APPLIANCES CO. Feb. 12, 1962, No. 5240/62. Addition to 892,543. Class 83 (4). A modification or improvement in the pipe flaring tool as disclosed in the parent Specification comprises a movable barrel slidably mounted in the holder behind the sleeve means and containing the cartridge chamber at its rear end and being held in a rear position by removable means connected at the rear end of the holder, the movable barrel being joined with an opening connecting the cartridge chamber with the rear ends of the sleeve means and the piston in the sleeve behind the flaring means, and means connected with the movable barrel for manually moving it forward in the holder after removal of the removable means to force the barrel into frictional engagement with the piston to permit the piston to be pulled back in the sleeve means. The tool housing is provided directly behind the die 3 with diametrically opposed holes 13 for receiving a removable pin 14 that serves as a stop or locator for the end of the pipe. Screwed on to the housing is a tubular holder 16 for sleeve means 17 slidably mounted on the holder and engageable with the die 3 for forcing the die segments against the converging walls of the die holder 4 and into gripping engagement with the pipe. The rear end of the holder slidably receives a barrel 26 provided with a collar 29 having radially disposed handles 31 extending through longitudinal slots 32 in the holder. A breech-block 33 containing a firing pin 34 is screwed on to the rear end of the holder. Slidably mounted in the sleeve 17 is a piston 40 provided with a pipe flaring head 41. A tapered projection 44 on the barrel frictionally engages a tapered bore 43 in the piston and holds the piston in its retracted position in the sleeve. In operation, after the firing pin has been struck, the expanding gases resulting from the detonation of the cartridge, pass through passages 45 in the barrel 26 and drive both the piston and sleeve forward. The die is driven forward by the sleeve and grips the pipe so securely that it is not driven through the die when struck an instant later by the flaring head. Before the flared pipe is removed from the tool the breechblock is removed and the barrel is pushed forward by means of the handles 31 to wedge the projection 44 on to the tapered bore of the piston after which the barrel is retracted together with the piston and the flared pipe is removed from the tool. By connecting the pin 14 to the breech-block by means of a lanyard 47 it can be made impossible to screw the breechblock on to the rear end of the barrel until after the pin has been pulled out of the housing. Inadvertent firing of the tool with the pin in position is thus avoided.

Title: Device for code sorting postal items
IPC: B07C3/00
Filed: 1975-02-07
Abstract: 1466223 Postal mail sorting systems DE STAAT DER NEDERLANDEN REPRESENTED BY DE DIRECTEUR - GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE 7 Feb 1975 [8 Feb 1974] 5337/75 Heading B8A In a letter sorting system the letters are fed at 30 (Fig. 4) by an operator into a cassette 10 (Fig. 11) which has been diverted from its position on a conveyer 1 (Fig. 1). The diversion is effected by a belt 25 (Fig. 7) which has a cassette engaging pin 24. The latter is operable by a solenoid actuating arm (26) (Fig. 8, not shown). Provided an empty cassette is present the pin 24 is then able to engage the cassette which is thereby drawn out from its associated conveyer carrier 9 (Fig. 11) and is then engaged by a conveyer belt 31 running parallel with and at the same speed as the conveyer 1. The cassette is then engaged in succession by a convey 33 and worm shafts 36, thereby to be moved into a position 37 directly under the letter receiving aperture 30. After the operator has struck the final key of a destination code, the letter is then advanced to a position 39 and is then returned to its original carrier 9 by belts 46 and 49. The latter carries troughs (45), (47), (48) (Figs. 14-18, not shown) for engaging successive cassettes. At a series of discharge stations (Fig. 6, not shown) letters are discharged according to their code to an appropriate one of a series of containers (4). This is achieved by the cassettes each having a releasable bottom flap 19 (Fig. 12). The latter is normally held by a catch 20 by the centring action of spring-loaded levers 21 in which the flap 19 is hinged. The levers 21 are deflected to release the catch 20 when a code signal actuates a solenoid to deflect a roller 23. Mail which is automatically read by a unit 6 (Fig. 1), may be fed into a side aperture of the cassette. In a mechanism (Fig. 5, not shown) for effecting this a reading head diverts letters with no recognizable code to a stacker (54). At the discharge station (Fig. 6, not shown) there is a separate receptacle (5) in each container (4) for the automatically read mail.
