Title: Improvements in automatic feed weighing machines
IPC: G01G13/00
Filed: 1946-08-29
Abstract: 655,934. Automatic feed weighers. MOLENSCHOT, J. L. F. M. Aug. 29, 1946, No. 25960. Convention date, July 8. [Class 143] In order that the weighing container 1 of an automatic-feed weigher shall execute only slight displacements, it is directly connected by a rod 39 to a point on the weigh - beam 2 5 closely adjacent the fulcrum 25a, and the weighbeam is connected to a lever 34 which operates electric contacts to close the feed hopper 2 and release the discharge flap 18 of the weighing container when the required weight is reached. The embodiment shown operates continuously. During filling the shutter 3 of the feed hopper 2 is held open by an electromagnet 4 while the discharge flap 18 is locked in its closed position by engagement of a roller 15 on a pivoted arm 14 behind a quadrant 16 moving with the flap. When the required weight is nearly reached and the beam 25 commences to move, contacts 35 at one end of the lever 34 are separated and this, through a relay 40, de-energizes the electromagnet 4 allowing the shutter 3 to fall to a dribble feed position determined by the engagement of a lug 5 under a pivoted catch 6. When the weight is made up the further movement of the beam 25 and lever 34 closes contacts 32b, 32a, either together or in immediate succession, and these contacts, through relays 41 and 42, energize magnets 7 and 11, the former to release the shutter 3 to stop the feed and the latter to raise the arm 14 out of locking engagement with the sector 16 allowing the discharge flap 18 to fall open under the weight of the material. After discharge of the material, the flap 18 is reclosed by a counterweight 20 and this operates starting contacts 10 in the circuit of relay 40 to initiate the next cycle. Stopping operation. The quantity weighedout can be checked, whilst still in the weighing container 1, by operating a switch 43 which breaks the circuit of relay 42 and prevents operation of the magnet 11 and opening of the dischage flap 18. After reading any error of balance from a dial 37, the switch 43 is closed and the automatic operation resumed. Loose weight apparatus. The weigh-beam 25 is loaded the required amount by loose weights 22, which can be selectively applied to a carriage 21 on the weigh-beam by turning a knob 24. Cams 29 turning with the knob selectively rock bell-cranks 31 which are adapted to engage under heads 28 on supporting rods for the weights so as to load them onto the beam carriage 21 or lift them clear.

Abstract: 1476575 Photomultipliers G D SEARLE & CO 20 June 1975 [21 June 1974] 26300/75 Heading HID [Also in Division H4] In a scintillation camera of the type comprising a plurality of photomultiplier tubes (see Division H4) each tube viewing (preferably via a light guide plate) a particular area of a laminar scintillation crystal which in use is exposed to gamma rays, each tube includes a plurality of anodes A1P10, A2P10, e.g. four, each responsive to scintillations emanating from a determinable sector of the particular area viewed by that photomultiplier tube. The resulting anode output signals are processed to determine the co-ordinates of the incident gamma rays and displayed or otherwise recorded. This camera has improved spatial resolution, or alternatively a larger field of view may be viewed without reducing the degree of resolution since a plurality, e.g. four, reference points are produced for each photomultipler tube. Electrons emitted from photocathode 72 are channelled by electron partitions 3, 4, 8, and 9 and are attracted to respective ones of the four slat arrays 63, 61, 64, and 62 in the tubes dynode array and then to the respective anodes. The tubes are pressed into contact with u.v. transmitting light guide (45) adjacent glass disc (39) and the encased hygroscopic scintillator (37) (Fig. 2, not shown). Crystal (37) may be thallium activated sodium iodide.

Title: A new or improved drive coupling
IPC: F16D3/62
Filed: 1947-10-02
Abstract: 630,824. Universal joints. METALASTIK, Ltd., and HIRST, A. J. Oct. 2, 1947, Nos. 26557/47, 1793/48 and 22103/48. [Class 80 (ii)] Comprises flexible couplings with substantially radial rigid drive-transmitting links having rubberbushed end connections to axial pegs or sleeves. The links may serve to connect driving and driven members directly together, or each to a floating intermediate member. As shown applied to couple a marine engine to reduction gearing or a propellor, rubber bushes 15, Fig. 2, are bonded directly between the pins 14 of three welded-up links 13 and the interior of forged housings 16 bolted to a driving flywheel 10 and to the cut-away flange 19, Fig. 1, of the input coupling sleeve 11 of a gearbox or like transmission member. According to the first Provisional Specification, six links are used and the bushes are bonded to sleeves fitting the pins and housings respectively. Alternatively, the bushes may be bonded between outer sleeves secured to the links and inner sleeves secured to pegs on the flywheel and flange. In the form shown in Fig. 5, as used to couple generators to diesel engines, solid forged links 22 are connected .in this way, the links being slightly inclined to the radial position in the absence of torque so as to pass therethrough on initial loading and give a high initial flexibility. To ensure that the stiffness of such a coupling is at a minimum when the links are radial, the lengths of the links can be such that they are in compression in this position. To facilitate dismantling; the flange pegs may comprise bolts 31 engaging a retainer cap 33 held from rotation relative to a main hexagon-headed sleeve 29 by a projection 34 thereon, a locking tab washer 36 being provided. In a form suitable for use between the engines and gearboxes of heavy rail or road vehicles such as mining locomotives or, according to the third Provisional Specification, road rollers, particularly those with two or three cylinder four-stroke diesel engines, driving and driven two-armed spiders 40, Fig. 6, at right angles, are each connected to a floating coupler 48 (which may be as shown or in the form of a ring or a pair of parallel rings lying outside the spiders) by a pair of diametrically opposed links 42. In forms of coupling where the links are always in tension, part-cylindrical bushes on the outer sides of the outer pins and the inner sides of the inner pins can replace the complete bushes. The load capacity of the bushes may be increased by using one or more intermediate metal sleeves therein. Instead of bonded rubber bushes, non-bonded but precompressed bushes or plain rubber sleeves compressed axially may be employed.

Title: Improvements in electronic discharge devices
IPC: H01J17/38
Filed: 1927-10-08
Abstract: 278,751. Manhattan Electrical Supply Co., Inc., (Assignees of Hendry, W. F.). Oct. 8, 1926, [Convention date]. Vacuum tubes. - The operating area of one or both electrodes of evacuated or gas-filled discharge devices is restricted and breakdown of the insulating support of an electrode adjacent the electrode is prevented by surrounding the electrode by a sleeve of insulating or conducting material, the width of the space between the sleeve and the electrode being much less than the length of this space and being slightly greater than the mean distance travelled by an electron to produce ionization at the impressed voltage. In a half-wave rectifier, a carbon electrode 2, Fig. 1, on an insulating support 5 is surrounded by a sleeve 12 held in a place by a ferrule 14, the support and sleeve 12 being of porcelain, lava, &c. or the sleeve 12 being of metal separated from the base 8 of the electrode 2 by a washer of such insulating material. An aluminium lead 7 passes through a glass stem 11. The other electrode may be an aluminium hemisphere 3 on an aluminium rod 15 protected by a glass stem 17, the electrode 2 being at the centre of the hemisphere. 'The bulb 1 is filled with neon at 2-3 mm. pressure. During the half-wave in which the electrode 2 is negative, it is surrounded by a screen of positive ions preventing electrons passing to the electrode 3, the potential drop between the electrodes taking place within a short distance of the electrode 2 and producing rapid acceleration of positive particles which, without the sleeve 12, would damage the support 5. With the sleeve 12 just beyond the screen of positive ions, such positive particles which enter the gap 19 are drawn to the electrode 2 or stopped by collision with ions or gas atoms and do not penetrate as far as the point of contact of the electrode 2 with the support 5 or sleeve 12. To ensure this, the radial width and longitudinal depth of the gap 19 should be in the ratio of 1 to 8 or more for higher voltages, for example, should be 1/64 to 1/8 inches for 1100 volts. The gap is enlarged at 18 to accommodate carbon dust from the electrode 2. In a full-wave rectifier, two electrodes 2 in sleeves 5 may be arranged side by side near the centre of the electrode 3 or the electrodes in Fig. 1 may be repeated as in Fig. 3.
