Title: Improvements in or relating to baling machines
IPC: A01F15/14
Filed: 1956-08-23
Abstract: 852,331. Baling-machines. POWELL, W. N., POWELL, A. F., and ANDERTON, H. Nov. 21, 1957 [Aug. 23, 1956], No. 25725/56. Class 94(1). In a baling-machine, the shaft 24 of the tying needles 26 carries a sprocket 23 coupled by a chain 22 to a sprocket 19 carrying an arm formed with a slot or track 18, 20 engaged by a roller or pin 17 eccentrically mounted on the knotter shaft 10. The slot or track comprises a straight portion 18 and an arcuate portion 20 so arranged that the sprocket 19 is oscillated through an angle of approximately 85 degrees during three quarters of a complete rotation of the knotter shaft and remains stationary during the remainder of its rotation, the needles 26 being moved through the baling chamber during the 'latter part of the final stroke of the compressing plunger and tying of the bale being effected when the plunger is at the end of its final compression stroke. The needles are returned to their inoperative position before the plunger commences its next working stroke. The plunger is reciprocated mechanically and is slotted to allow passage of the needles. Rotation of the shaft 10 is initiated by a trip device after a predetermined number of strokes of the plunger.

Abstract: 588,274. Gearing for starting machinery. NEWTON & CO., Ltd., L. H., WHITING, R., HORDERN, MASON, & EDWARDS, Ltd., and EDWARDS, W. G. Dec. 22, 1944, No. 25742. [Class 80 (ii)] In a driving gear for power presses and the like having a continuously-rotating driving wheel which operates the machine-shaft intermittently through a manually engaged onerevolution key-clutch, the shaft carries a poweroperated freewheel device which sets it in motion before the key-clutch is engaged. As shown, the machine-shaft 10 carries a ratchetwheel 30, whose co-acting pawl-carrying arm 23 is operated by a compressed air cylinder 26 pivoted to the machine frame. Immediately before the key-clutch engages, an air control valve 21 operated through a link 20 by the keyclutch engaging pedal (not shown) connects the cylinder 26 to a supply-pipe 32 to set the shaft 10 in motion. A<1> spring 19 returns the lever 23 when the cylinder 26 is connected to an exhaust-pipe 37. The range of movement of the lever 23 is controlled by a manual reducing valve 31, and is limited by two stops 27, 28, the latter enabling the ratchet to act as a detent to prevent backward rotation of the shaft 10. The spring 19 may be disposed inside the cylinder 26, or the latter may be double-acting.

Title: Improvements in or relating to wireless receiving apparatus
IPC: H03G3/26
Filed: 1937-09-27
Abstract: 502,834. Wireless receiving - sets. GENERAL ELECTRIC CO., Ltd., and BLOCH, A. Sept. 27, 1937, No. 26139. [Class 40 (v)] A muting-device is automatically brought into use when the tuning control of a wireless set is rotated quickly. The tuning shaft 1 carries a gearwheel 2 meshing with gear-wheel 6 mounted on the same axle 4 as fly-wheel 5, the axle being - carried by frame 3 which is loosely mounted on shaft 1. When shaft 1 is turned slowly, the fly-wheel 5 is rotated slowly but frame 5 is not moved. At faster speeds, however, the flywheel acts as a brake and the frame 5 tends to swing about shaft 1 and operates muting contacts 7, 8. If the fly-wheel is allowed to drive the tuning control, as in fly-wheel tuning, the frame 3 swings between the two contacts 8 during the change-over from being the driven to the driving member, but the circuit can be suitably designed to maintain muting during the change-over. An embodiment using a cable drive and a stiff rubber shaft capable of deflection is also described. The Provisional Specification states that the fly-wheel may be replaced by a vane type brake. British Specification 433,555, French Specification 813,743 and U.S.A. Specification 2,038,332 are referred to.

Title: Coated nuclear fissile or fertile material and method and apparatus for preparation thereof
IPC: G21C3/62
Filed: 1962-07-09
Abstract: <PICT:0949742/C1/1> Uranium dioxide in particulate form has each particle or pellet coated with alumina, zirconia, or yttria modified by a minor amount of chromia.  The coating may contain from a trace up to 5% by weight of chromia and has a thermal expansion substantially the same as that of the uranium dioxide, so that cracking of the coating is avoided.  As shown, the uranium dioxide is fluidized in reactor 18 by means of hydrogen flowing through lines 1, 13, 17 into the base of the reactor. Part of the hydrogen passes through line 4 to heated vaporizer 7 containing aluminium chloride which becomes entrained with the hydrogen, the mixture joining line 17 at 11.  Helium is supplied through line 34 and bubbles through vaporizer 40 containing liquid chromyl chloride which is entrained with the helium and also is fed into line 17 at 44.  Another portion of the hydrogen flows via valve 21 to heated vaporizer 24 where it bubbles through water and passes, together with water vapour through line 28 and tube 32 to a point 33 inside the reactor about halfway down the fluidized bed 19; shunt line 29 is used to adjust the water vapour concentration in the reactor.  Electric heaters 46, 47 maintain the fluidized bed at a temperature of 300-1400 DEG  C.  In the lower part of the fluidized bed below point 33, chromyl chloride is reduced to chromia, while in the upper part of the bed aluminium chloride is hydrolysed to alumina.

Abstract: 1,011,151. Spray carburetters. BENDIX CORPORATION. July 9, 1962 [July 7, 1961], No. 26305/62. Heading FIB. In a constant suction type carburetter with a metering needle 74 operated by a suction actuated piston 56, controlling a fuel orifice situated in a ridge 19, enrichment of the mixture at starting or full throttle is obtained by a shaft 78 which restricts the air flow beneath the piston. The shaft 78 has a segmental crosssection 79 which normally forms part of the sloping side 21 of the ridge 19. The minimum air flow cross-section is determined by projections 77 on the piston 56 contacting the ridge 19. Rotation of the shaft 78 at starting first closes the air passage beneath the piston 56 and then lifts the piston slightly to increase the fuel flow through the orifice, providing a rich starting mixture. The shaft 78 may be operated by linkage connected to the throttle valve operating linkage; alternatively it may be controlled conjointly by a bimetallic strip and suction operated piston or engine speed responsive solenoid. In Fig. 8 the shaft 278 controlling the choke 78 is urged by a spring 289 towards its enriching position and is held in its normal position during normal running by a suction actuated piston 282. At full throttle, the suction decreases and the spring 289 moves the shaft to its enriching position in which it partially restricts the air passage.

Abstract: 1,269,158. Photographic exposure processes. BOFORS AB. May 27, 1969 [May 24, 1968], No. 26798/69. Heading G2C. Sequential images are recorded upon a photographic plate, each image being exposed through a different pattern. The process is described as applied to recording the image screen of an IR camera used to detect deviating temperature distributions over the surface of the human body which are indicative of potential cancer regions, the sequential images corresponding to different temperature ranges. The process thus allows overlap of the different images upon the same photographic plate, the patterns permitting discrimination of the images in the subsequently developed plate. Transverse movement between the image of the viewing screen and the photographic plate may be effected between each recording. Part images of a raster pattern, e.g. delimited by circles, triangles or rectangles may be obtained for each image to further assist discrimination. A pattern plate consisting of a line raster may be rotated through an angle between each recording and coupled to the camera shutter mechanism. The pattern plate may be located in front of the viewing screen or the photographic plate.
