Title: Conveyor System
Inventor: NASLUND ERIK INGEMAR
IPC: B65G47/62
Filed: 1966-11-15
Abstract: 1,164,168. Endless conveyers. FMC CORP. 15 Nov., 1966, No. 51049/66. Heading B8A. A main monorail conveyer E has dual sideby-side carrier shoots 24, 24a which are loaded with bags at stations 22 and are displaceable selectively to dump a bag 26 via a system of conveyers (114) and (116) (Figs. 7 and 8, not shown) and stationary shoots (110), (118), on to a similar carrier shoot 31, or 31a of a distributing conveyer S. As shown, there are two main conveyers E3, E4, each feeding two conveyers S1 S2. The shoots (110), (118) and conveyers (114), (116) are arranged so that a sack on a right hand carrier shoot 24 of the conveyer E3 or E4, is transferred to a left hand carrier shoot 31a of the conveyer S1 or S2. Similarly a sack on a left hand carrier shoot 24a of either conveyer E is transferred to a right hand carrier shoot 31 of the selected conveyer S. If it is desired to transfer a sack from a shoot 24 to a shoot 31, a transfer is effected at a station T5 at a loop 160 of the conveyer E, from the shoot 24 to a shoot 24a of another carrier. When the transfer to the conveyer S takes place, the sack will then pass to a shoot 31 as intended. In a modified arrangement (Figs. 1A-1C, not shown) there is no loop 160 and associated transfer station T5. There is instead an additional transfer station (Ta) at the other point of crossing of each conveyer S1 S2 below the main conveyer. The shoots at each of these stations are arranged to transfer bags from a shoot 24 to a shoot 31 (or from a shoot 24a to a shoot 31a). Shoots 31 and 31a are programmed by electronic means (not described) or are manually controlled to discharge selectively into destination shoots 32, 32a. The conveyers (114), (116) are so controlled by photo-electric means that each conveyer is maintained at rest until its preceding conveyer has discharged its bag. Similarly a trap door (142) prevents discharge of a bag to an already occupied carrier shoot of the conveyer S1 or S2. Each pair of carrier shoots 24, 24a is pivotally mounted at 50 (Fig. 5) on a member 48 depending from an endless roller chain 44. The shoots in normal transit are maintained in raised position (L.H. side of Fig. 5) by the engagement of a latch 66 with a member 68. At a selected discharge station, the setting of a memory member 75 is such as to engage a switching system (76), (72) (Fig. 2, not shown) so that the plunger of a solenoid (72) carried by the conveyer framework is projected into the path of a lever 70 rigid with the latch 66. After discharge has taken place, the shoots 24, 24a are lifted back into latching engagement again by the action of a ramp 84 and a gravity biased pivoted lever 88. Stabilizing wheels 102 are provided on the member 48 on either side of auxiliary rails 73 and further wheels 100 engage flared guides 98 arranged at the transfer stations to provide additional stability.

Abstract: 1,032,249. Reactors. REACTOR CENTRUM NEDERLAND. Dec. 15, 1964, No. 51087/64. Heading G6C. A nuclear reactor operated to provide a radiation source has its core positioned near the inner wall of the reactor vessel so that a narrow space is provided between the core and the inner wall, coolant being passed through this space. The reactor is intended to operate as a neutron source and the core position results in a minimum absorption of neutrons before they are received in the usage area. The core components 9, 10 are suspended by a framework 5, to be received in an aluminium rack providing core location. Neutrons from the core 3 cross the gap 12 and pass through a neutron diffuser 14 and a gamma radiation filter 15, to the usage area. A thermal column 11 is provided. Coolant, water, is supplied to the reactor tank 4 through a conduit 18 and discharged via outlet 16 whose entry end is adjacent the narrow space 12 so as to preclude stagnation of coolant and the consequent development of a hot spot.

Title: Vtr signal discriminating apparatus in a television receiver
IPC: H04N5/445
Filed: 1974-11-26
Abstract: 1448898 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 Nov 1974 [26 Nov 1973 (2)] 51170/74 Heading H4F A television receiver includes apparatus for determining whether a received signal is derived from a video tape recorder or a broadcast transmission by detecting the presence or absence of head switching noise in the output of the sync. separator of the receiver. The output of the sync. separator, Fig. 2(b), which includes head switching noise 62 if it is derived from the output of a video tape recorder is supplied to a gate 28 which is opened by a gate pulse, Fig. 2(e), from a generator 22, for a predetermined period prior to each filed synchronizing pulse, Fig. 2(d), this period including the head switching noise if such is present. The sync. pulses, Fig. 2(f), passed by gate 28 are counted by a counter 24; if head switching noise is present the output of counter 24 is one more than if head switching noise is absent, and a decoder 25 provides a "1" output if the received signal is from a video tape recorder or a "0" output if the received signal is derived from a broadcast transmission. So that head switching noise coinciding with a line sync. pulse does not produce erroneous operation the output of decoder 25 is passed to a temporary memory 26. If decoder 25 produces a "1" output this is stored in memory 26 until the memory is reset by a pulse, occurring once every N fields, from a generator 29; generator 29 also provides to a memory 27 a pulse immediately before the pulse supplied to memory 26 so that memory 27 reads the content of memory 26 immediately before memory 26 is reset.

The block 5 is rotatable on a seating 6 between a position in which a radial arm of the chamber 7 is in axial alignment with the pistol firing pin (10), Fig. 2 (not shown), and a second position in which the spent cartridge is ejected into a pocket 11 by means of a rod 13. In its passage between the two said positions the radial arm 7 passes by the end of a passage 12 in the seating 6. A magazine which comprises outer and inner tubes 18, 19 is held by a knob 20 in the passage 12. When loading the magazine it is withdrawn from the passage 12, a secondary spring 27 driving the inner tube 19 lengthwise of the outer tube 18 such that a ball 30 is transferred from a groove 32 into a clearance 33 where it fits into a hole 31 in tube 19 (Fig. 3). A cartridge is inserted manually, rim forward into the flanged end 26 of tube 19 against the action of a main spring 29 and plunger 28, thus returning the ball 31 to groove 32. On relieving manual pressure, the inner tube is again forced outwardly by spring 27 but the cartridge is held in the magazine by the action of the ball 30 abutting its shell and rim. Further cartridges are inserted in the magazine thus compressing spring 29. On reassembling the magazine in passage 12, a flange 25 abuts a shoulder 26 thus driving the inner tube 19 inwardly of tube 18, and the ball 30 is returned to groove 32 thus allowing main spring 29 to drive the column of cartridges towards the seating 6. Each time the radial arm 7 passes from the pocket 11 to the firing pin (10), a cartridge is transferred from the passage 12 to the arm 7. In further embodiments (not shown), the magazine comprises a single tube formed with ball-engaging holes surrounded by an internally grooved collar and a secondary spring, the ball being in radial register with the collargroove. Alternatively the magazine may comprise a cylindrical pack whose ends are closed by frangible diaphragms.
