Title: Improvements in apparatus for feeding material in pellet form
IPC: B30B15/30
Filed: 1944-10-09
Abstract: 631,935. Delivering articles from shoots. GENERAL ELECTRIC CO., Ltd., and HICKLING, F. J. Oct. 9, 1944, No. 19377. [Class 78 (i)] Means for feeding pellets from one or more tubular containers in which they are arranged in piles comprise (1) retaining means at the bottom of each container which is movable to release a pellet and (2) means normally disposed outside the container which can be moved through the wall into temporary engagement with a pellet to retain this pellet and those above it while the pellet below it is being released. In Fig. 1, pellets 3, stacked in the tubes 1, rest on the "solid" parts of the gates 4 and 6. When the gates are slid to the left the lowest pellet in the tube falls through the recess 7 into the recess 5 and since the gates are connected to the rod 14 which operates the pivoted tumbler 10 mounted on the outside of the tube, the tumbler falls and the finger 12 attached thereto protrudes through the hole 13 in the tube 1 thus arresting the pellet 3<SP>1</SP> as shown in Fig. 2. By sliding gate 17 relative to gates 4 and 6 the pellet is further transferred. The tip 18 may be added to the finger 12 to suit the material of the pellet and may be adjusted so that two or more pellets fall at the same time. Specification 631,934, [Group V], is referred to.

Title: Device for transferring objects to a container in a leak-tight manner
Inventor: MENISSIER PIERRE
IPC: G21F7/005
Filed: 1971-06-08
Abstract: 1279940 Glove boxes COMMISSARIAT A L'ENERGIE ATOMIQUE 8 June 1971 [19 June 1970] 19433/71 Addition to 1230550 Heading B4Q A device for transferring objects from an enclosure to a container in a leak-tight manner through a feed tube the same diameter as the container opening includes a perforated, flexible sealing tape 14 which is fed from the exterior into the enclosure which is liable to be contaminated along a path which causes successive holes 18 of the tape 14 to pass in front of the feed tube 8. The device may be used in an installation for the transfer of nuclear fuel pellets between a glove box 4 which is contaminated or liable to become contaminated and cans 6 which are located within a clean glove box. The end of the feed tube 8 is attached to a guide plate 10 around a tubular passageway 12. The guide plate 10 is provided around the outlet of the passageway 12 with an annular shoulder against which the tape 14 is continuously applied by means of a film gate 16. A motor 24 actuates a drive capstan 26 against which the tape 14 is applied by a pressure roller 28. A bearing roller 30 carried by a rocker-arm 34 is capable of moving between a first position in which it maintains the tape 14 against the guide plate 10 and a second position in which it frees the tape. A programmer 40 when triggered manually starts up the motor 24, thus displacing the tape 14. When a pre-centering perforation 22 (of Figure 2) comes opposite a lamp 44 and a photoelectric cell 46, the cell transmits to the programmer 40 a signal which stops the motor 24 and actuates the mechanism 42 of the rocker arm 34. The roller 30 lifts, releases the tape 14 and inserts two pins 36 through two perforations 20 in the tape 14, one on each side of the corrsponding hole 18. During this action, the perforations 20 are accurately centred by the pins 36, the tape being moved to a slight extent if necessary. Transfer of the pellets can then take place. The programmer 40 is again triggered manually to initiate operation of the mechanism 42 which releases the pins 36 and re-applies the roller 30 against the tape 14, the motor 24 also being started up. When the perforation 22 referred to above comes opposite a second lamp 44<SP>1</SP> and photoelectric cell 46<SP>1</SP>, a signal is delivered to the programmer 40 which stops the motor 24 but does not operate the mechanism 42. The loaded can 6 can then be removed and a fresh can brought into position for a further loading sequence.

Title: Ultra low current amplifier
IPC: H04R25/00
Filed: 1975-05-08
Abstract: 1475845 Transistor amplifier; deaf aid circuits DAHLBERG ELECTRONICS Inc 8 May 1975 [9 May 1974] 19463/75 Headings H3T and H4J A low current deaf-aid amplifier has output stage comprising complementary transistors 30, 31 with collectors connected 32, in series across the single cell D.C. power supply 10, biased as required and feeding an A.C. load (e.g. low impedance receiver 40), the D.C. being blocked by a capacitor 42. The input 15 is from a microphone 14, possibly requiring its own power supply 13, feeding via class A preamplifier stages 21, 24 the bases of output transistors 30, 31, the by-passed resistor 33 being adjusted to bring the series bias current to the required value for class A or AB. A.C. negative feedback across capacitor 42 is adjusted by resistor 44 in voltage divider 44, 45 to provide the required overall gain, subject to volume control 17; D.C. feedback through the winding of receiver 40, controlled by resistor 45, sets the quiescent voltage of the output line 32, to half the supply. Low frequency gain is reduced by capacitor 42, and very high frequencies (>5000 Hz) are suppressed by capacitor 43: in a second embodiment (Fig. 2, not shown) a more level response is obtained by means of negative feedback taken from a resistive voltage divider between line 32 and ground, with a by-pass capacitor across the lower end of the divider if high frequency suppression is required.

Abstract: 1,140,060. Blow-moulding; integral handle &c. PHILLIPS PETROLEUM CO. 3 May, 1966 [4 May, 1965 (2)], No. 19477/66. Heading B5A. Hollow articles having integral hollow handles &o. are formed by placing a parison between two or more mould parts, which are then closed, partially expanding the parison, pinching out a portion of the parison to form the handle and then completely expanding the parison. As shown in Fig. 2, the parison 10 is enclosed by mould halves 1, 2, and it is pinched by extending members 7, 8 to form handle (12, Fig. 3, not shown) and chamber (6). The parison is then blown by needle 9 inserted into chamber 6, which communicates with handle (12) via channels 23. After removal from the mould, chamber 6 may be pressed apart from the article leaving the holes 28 formed by channels 23 unnoticeable (Fig. 6, not shown). Alternatively, the blowing needle may pierce the parison in the body portion thereof, the resultant hole (128) being on the outside of the article (Fig. 9, not shown).

Title: Engine speed governors
IPC: G05D13/40
Filed: 1955-07-06
Abstract: 790,865. Gas-turbine plant. BENDIX AVIATION CORPORATION. July 6, 1955 [July 28, 1954], No. 19554/55. Class 110 (3). [Also in Group XXIX] An hydraulic speed governor controlling the supply of liquid fuel to the burners of a gas turbine comprises a housing 40 having ports 42, 44 connected to a fuel supply pump and a conduit supplying the burners respectively and a piston valve 46 slidable in a ported sleeve 60. The piston valve 46 is loaded by a spring 130 to open sleeve ports 62 against the pressure (P-S) of fuel supplied to a chamber 178 connected through a restriction 176 and a pressureregulating valve 172 with the port 42. A servovalve 116 operable by governor weights 72 rotatable by the turbine controls leakage from the chamber 178. To ensure that the pressure (P-S) is unaffected by the pressure at the port 42 any leakage between the sleeve and the valve piston is directed to the supply pump inlet through an annular groove 160, ducts 162, 166 and ports 152, 156 and leakage between the sleeve and the valve piston guide 56 to the pump inlet through the ports 152, 156. A pilot-operated, bifurcated lever 100 adjusts the loading of the governor spring 96 to determine the operational speed of the turbine. If, for example, the load on the turbine decreases, its speed increases whence the governor weights move the servo valve 116 to reduce leakage from the chamber 178. Increased pressure in the chamber 178 then overcomes the spring 130 to reduce the opening of the ports 62 and the amount of fuel to the burners to return the speed of the turbine to its adjusted valve. In the event of pressure failure in the chamber 178, for example, due to the valve 172 failing in its closed position, the spring 130 urges the piston valve 46 rightwardly so that its extension 118 engages the servo valve 116 whence the pilot may operate the valve 46 manually by means of the lever 100 to either accelerate or decelerate the turbine. Contact between a flanged nut 140 and a lever 142 limits the maximum opening of the sleeve ports 62 and between the nut and an adjustable stop 146 their minimum opening. The position of the lever 142 being a function of certain engine-operating parameters, such as engine speed and compressor inlet temperature.

Abstract: 699,603. Cribbage boards. STACKHOUSE, D. L. Aug. 5, 1952, No. 19693/52. Class 132(ii). In a cribbage board (Fig. 1) in which each player moves a pair of pegs down a row of holes 13, up a row of holes 14, round the holes again and finally into a finishing hole 20, the first or second round is indicated bv providing under the row 13 a slider 25 having holes 26 which can be brought into alignment (first round) with holes 13 or out of alignment (second round) with holes 13 and the pegs 35 have a long conical end 37 engageable in aligned holes 13 and 26 and a cylindrical end 36 penetrating only the holes 13. Holes 14 are the same depth as holes 13, 26 combined and all the holes are inclined in the direction of travel of the pegs to indicate this direction. Large diameter starting holes 22, 21 are disposed above holes 27, 28 in slider 25 which is urged against a stop 29<SP>1</SP> by a spring 32. In use, slider 25 is punched in and the pair of pegs is inserted, conical end down, in holes 27, 22 and 28, 21 to lock the slider in position. If the peg is upside down, it will cant over, the holes 22, 21 being larger than the ends 26. Scoring proceeds until both pegs clear row 13 whereupon slider 25 moves up to put the holes out of register. On the second round, the peg ends 36 must be used because insertion of ends 37 in holes 13 would cause the pegs to cant and this canting would also occur in finishing hole 20 if the peg were inserted therein at the end of the first round.

Abstract: 1,172,203. Olefins. UBE INDUSTRIES Ltd. 25 April, 1968 [25 April, 1967], No. 19755/68. Heading C5E. Olefins, e.g. ethylene, propylene and butenes are produced by cracking liquid hydrocarbons by contact at 600-1000 C. for 0À05-3 seconds with a bed of solid particles fluidized by a gas containing oxygen and steam (and optionally inert gas such as N 2  or CO 2 ), wherein, as shown in the Figure, part of the fluidizing gas is fed via 2 through a gas distributer 3 which is preferably funnel-shaped and is located below the bed, and the remainder is injected as a gas jet stream via 4 directly into the bed through one or more openings 5 located towards the centre of the gas distributer at a linear gas velocity higher than (e.g. 1À5-20 times) the superficial velocity of the whole fluidizing gas, thus causing the solid particles to circulate up the centre and down the sides of the reaction space. The gas jet stream preferably comprises steam only. The hydrocarbon feed may be injected directly into the bed together with the gas jet stream, e.g. via pipe 6 and nozzle 7 coaxial with pipe 4 and opening 5. The solid particles are suitably inorganic oxides, e.g. sand, magnesia clinker, cement clinker, alumina, silica or mullite, optionally in admixture with catalytically active oxides of Co, Ni, Cr or Fe. The feed may be crude oil, heavy oil, kerosene, light oil or naphtha, and may be admixed with steam or air.

Filed: 1921-07-23
Abstract: 189,176. Haddan, R., (Endless Belt Corporafion). July 23, 1921. Cigarette-tipping machines and appliances.- Cork or other tips for cigarettes are cut from a band, pasted, and pressed at intervals to the paper band of a continuousrod or other cigarette machine without interfering with the steady travel cf the band through the machine. In Fig. 1, a band of tipping material is led from the roll 4 over rollers 7, 8 and round the drum 10 where it is almost cut through at correct intervals by spring-controlled chisels 36 on the circumference of the drum 11. Pneumatic suction through the channels 22 retains the cut pieces on the drum 10, and paste, applied by the paste wheel 48 soaks into them while travelling to a pad 52. An arcuate flange 33 cuts off those channels not covered by tipping material. The pad 52 is supported and actuated as shown in Fig. 4, the pin 57 dropping into a slot 56 in the cam 55 slightly rotating the arms 58, 54 on the shaft 59 and causing the pad 52 to press the tip 50 to the paper band 2. The rotation of the spring- controlled shaft 64 permits a small travel of the pad with the paper. At the same time levers 78, 75, 92, 90, Fig. 1, actuated and returned by the swell of the cam 77 and the spring 85, slacken the portion 96 of the paper band and draw more paper from the roll 1, thus obviating the retardation of the band. The drums 10, 11 and the cam 55 are mounted on adjacent shafts and are driven. from the main shaft through suitable gearing. In a modification, the positions of the cutting and pasting wheels may be interchanged and the time of drying of the paste retained as before by reducing the diameter of the drum 10. Fig. 6 shows the manner of cutting a tipped rod to form cigarettes.
