Title: Improvements in and relating to apparatus for filling valve bags
IPC: B65B1/18
Filed: 1938-11-09
Abstract: 510,840. Filling-machines. BATES INTERNATIONAL BAG CO. Nov. 9, 1938, No. 32495. Convention date, Nov. 26, 1937. [Class 94 (i)] Bags such as valve bags are filled in an apparatus comprising a movable frame with a plurality of spouts, each spout being adapted to enter the valve of a bag, and the frame being movable to present the spouts in succession in line with a stream feed of weighed charges of material. The charges of material are dropped into a hopper 11, Fig. 1, and are fed by a belt 14 and pulley 15 as described in U.S.A. Specification 1,979,483 to a position with which one or other of the spouts 31, 32 is in register. The spouts are carried on a frame 27 suspended by rollers 29 on a frame 28, and reciprocated between two positions by a link 85 on a crankpin 84. In the position shown in Fig. 1 the spout 31 registers with the feed, and a valve bag, which has been placed on it when in the non-registering position, is clamped in position during the feed of the charge by a clamp 35, which is depressed by a resiliently mounted roller 39 on an arm 37 pivoted on the stationary bar 28. Another clamp 36, co-operating with the spout 32, is mounted on the other arm of a lever 33 and is raised by the same action to permit the placing of a bag in position while the first one is being filled. During the filling, the bottom of the bag rests on a saddle 45 provided with a central slot 46 and sloping sides 47. Two saddles are provided, one for each spout, and each saddle is pivoted at 48 on a standard 50 connected to the frame by a pin 52 and lever 53. The lever carries an antifriction roller 55 contacting with a shaft 56 having straight portions 57, Fig. 9, and a displaced portion 58. When at the filling position, the roller 55 corresponding to the spout 31 registers with the displaced portion 58 and a jigging motion is imparted to the saddle. When the bag and saddle are moved away from the filling position the roller registers with a straight portion 52 of the shaft and the jigging stops. At the same time, an arm 63 is raised by a roller 62 carried thereby passing up a stationary slope 68, contacts with a stop 61 on the saddle, and tilts it into a position shown in-broken lines in Fig. 2 and throws the bag off the machine. The machine may be set in motion by a hand lever 102 connected with a half-revolution rocking-key clutch mechanism which rotates the disc 83 carrying the crank arm 85. During this partial rotation, a lug 110 or 111 contacts with a trip member 112 to operate a rod 113 connected with a weighing device, which releases a charge into the hopper 11 so that it will arrive in the spout just after the bag is in the receiving position.

Title: Improvements in Echo-Sounding Equipment.
Inventor: GATEHOUSE RICHARD NORTON BINGH
IPC: G01S7/529
Filed: 1966-07-21
Abstract: 1,155,321. Echo-sounding; automatic gain control. BROOKES & GATEHOUSE Ltd. 21 June, 1967 [21 July, 1966], No. 32781/66. Headings H3Q and H4D. In an echo-sounder, receiver blanking to suppress the display of echoes other than the seabed echo is effected by generating a control signal having a duration dependent on the amplitude of the strongest echo in a sounding cycle. A peak rectifier with a long decay time and fed from the output stage of the receiver amplifier provides a D.C. output signal (d) having a level corresponding to the sea-bed echo (i.e. the strongest echo) amplitude and this level is compared in a coincidence circuit with a sawtooth sweep voltage (e) initiated at the beginning of each sounding cycle. When coincidence is reached the coincidence circuit output voltage (b) decays from a high to a low value. The voltage (b) provides a blanking waveform for the receiver amplifier, whose gain (g) is thereby increased from zero to maximum when coincidence is reached. The gain control is thus a closed loop system and is effective to position the coincidence instant just before the sea-bed echo arrival, so obliterating all but the sea-bed echo from the receiver output (c) which is applied to a neon-lamp, meter or digital type display.

Abstract: 1,078.293. Electric selective signalling. OLYMPIA WERKE A.G. Aug. 12, 1964 [Aug. 17, 1963], No. 32831/64. Heading G4H. A selective switching circuit, Fig. 1, comprises a number of stages any one of which responds to a square pulse on its associated terminal 9 to produce an output on load 12. Each stage has two AND gates 2, 3 with common inputs 4, 5 from gate 3 of the preceding stage. The other inputs 6, 7 are normal and inverse versions of the signal at 9. In normal operation AND gates 3 are open as far as a stage, say 1(<SP>n-2</SP>), which receives a pulse at 9. In this stage AND gate 2 opens and AND gate 3 closes. AND gate 14 associated with the stage is shunted by the relatively lowimpedance path through load 12. However, if two stages are pulsed simultaneously the earlier stage cuts the supply over lead 8 to all later stages and the pair of AND gates 14 provide sufficient current to energize alarm relay 16. Fig. 3 shows a chain switch for cyclic stepping. Positive and negative pulses S + and S - respectively set and reset a flipflop 31. Each stage is fed by an OR gate 36 fed by the reset halves of flip-flops of the two preceding stages. Each AND gate 37 is fed by its associated stage input and the reset output of the preceding stage, the AND gates 37 being connected by a series of OR gates 38 to an alarm output 44 which energizes in the ease of multiple operation.

Abstract: 284,836. Chignell, J. Dec. 29, 1926 Bottling.-In a counter-pressure bottling-machine having controlling means of the type described in Specification 17296/12, the bottle is freed from its air content by admitting carbon dioxide gas at a pressure less than that obtaining in the liquid reservoir preparatory to the filling operation. A liquid reservoir a comprises a bottom casting d insulated by a layer of spongy rubber f protected by a thin copper sheet g, and an annular ring b similarly protected on its outer surface. The bottom d is formed with a central aperture closed by a fittiug h. Liquid is supplied to the reservoir by a pipe m depending from its cover c and surrounding a pipe i connected to a supply of carbon dioxide maintained at a pressure less than that of the gas in the reservoir a above the liquid. The pipe i leads into a lower chamber j from which the gas passes through pipes 2 to the filling heads, each of which is provided with a control cock 3 of the type described in Specification 17296/12 but formed wtih additional ports and tappets 7 for the introduction of the gas. The cock is shown in Fig. 5 in the liquid filling position. In operation, low pressure gas from the chamber j enters the control cock by a port 25, passes along a passage 24 in the central rotatable members 18 thereof, and down the filling pipe 5 into the bottle 4. The member 18 is then turned to shut off the lower pressure gas supply and introduce the full counter pressure from rhe tank a, this movement opening the passages 21, 22, 23 and an annular space 16 around the filling tube 5. A further rotation of the member 18 bring it to the liquid filling position, the ports 19, 20 communicating with the tube 5 and the gas escaping through the passages 14, 15, 17, 26 and the pipe 11 to the reservoir j.

Abstract: 390,566. Tape-delivering machines. TENNANT, W. J., 111, Hatton Garden, London.-(Better Packages, Inc. ; 255, Canal Street, Shelton, Connecticut, U.S.A.) Nov. 30, 1931, No. 33175. [Class 18.] A machine for moistening and delivering long lengths of heavy tape is actuated by the reciprocation of a handle 18, Figs. 1, 2 and 6, secured to a wheel 19 and communicating motion by a spindle 20 to a spur wheel 21 which rotates a spur wheel 22 loose on the shaft 20 by pawls 23 so as to drive unidirectionally through a gear wheel 28, a rubber-tyred feed roller 16 which in conjunction with a second rubber-tyred roller 15 mounted beneath it, draws tape 12 beneath a guide 13a and through a channel 12c from a roll held frictionally between adjustable plates 80. The tape is delivered on the return stroke of the handle 18, the first half of this stroke being assisted by a spring 30 on the shaft 20, mounted so as to be tensioned during the second half of the forward stroke by the free end of the spring contacting a fixed stop 31 at the appropriate moment. The tape passes from the rollers 15, 16 through a channel 17 beneath a cutter 40 and over moistening brushes 61, 62 mounted in a water trough 63, a plate 64 pivoted at 65 and having adjustable weights 64a serving to press the tape on to the brushes. The cutter 41, Fig. 3, is operated by a solenoid 47 through links 49, 45, 44. The circuit being completed by the contact of a pin 54, Fig. 6, on the wheel 19 with a pivoted jaw 52 carrying one of a pair of contacts 56, 57, the contacts being normally held apart by a spring. The extent of movement of the handle 18 is indicated by means of a tape 37 coiled on a spring roller 39 and attached to the wheel 19, a mark on the tape moving past a scale 38 so that the length to be delivered can be read off. The spring 30 can be arranged to store energy on longer or shorter lengths of tape as desired. The electrical contact is so arranged that a conscious additional movement of the lever 18 is necessary to complete the circuit. The movement of the wheel 19 may be limited by a fixed stop so that a definite length of tape is delivered at each stroke.

Abstract: 748,438. Ultrasonic delay lines. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 15, 1954 [Nov. 30, 1953], No. 33277/53. Class 40 (8). The path of the acoustic beam in an ultrasonic delay device is flanked on either side by energy-dissipating means which prevent divergence of the beam. The device described is of the type using a cell 1 of a liquid medium, e.g. mercury, or a solid medium, e.g. quartz in which the acoustic beam suffers multiple internal reflection at an angle of incidence and reflection of 45 degrees. Where the cell is rectangular the reflecting sides 2, 3, 4, 5 have dimensions m/#2 and n/#2 where m, n are integral multiples of the beam width x having no integral common factor other than unity. In such a cell the beam undergoes m+n - 2 reflections as it is propagated from an input transducer 6 to an output transducer 8, each portion of the cell being traversed twice in mutually perpendicular directions. In the embodiment described the width y of the beam is 20 per cent less than the value x used in determining the dimensions of the cell. At the regions where the portions of the beam cross, collimating posts 20 are positioned with their axes parallel to the reflecting sides. The posts are omitted in those positions where their presence would cause reflection of energy into the transducer 6. In the case of a solid cell the posts are formed by holes in the medium which may be filled with an absorbing substance. The sides of the holes are preferably made rough. Steel screws are stated to form suitable posts for a mercury cell. Reflections from the top and bottom of the cell may be prevented by forming ridges in these surfaces.

Abstract: 656,045. Pulverulent-fuel burners. KOPPERS CO., Inc. Dec. 24, 1948, No. 33299. Convention date, Dec. 29, 1947. [Class 75(i)] [Also in Group XII] Powdered fuels are gasified by forming a suspension of the fuel in oxygen.or oxygen enriched air, injecting the suspension into a gasification chamber where some of the fuel burns in the oxygen and raises the unburnt portion to a high temperature, the heated fuel then being contacted with steam or carbon dioxide which has been preheated by admixture with the hot products of combustion of a carbonaceous fuel in oxygen or oxygen enriched air. In one form the apparatus comprises a conical gasification chamber 1 having at its narrow end a burner head for introducing the fuel and gasifying agents. A preformed suspension of fuel in oxygen is forced into the chamber through pipes 3 and ignited, part of the fuel burning in a jet flowing axially along the chamber. An annular channel 6 is formed in the refractory material surrounding the pipes 3 and a number of combustion spaces 8 arranged to open into this channel. A steam-oxygen mixture is injected into each space 8 through a nozzle 9, a fuel gas also entering each space 8 from an annular gap around each nozzle 9 and burning in the oxygen, the heat liberated raising the temperature of the resulting combustion-product-steam mixture, which then passes through the channel 6 and is injected into the chamber 1 through an annular nozzle 7, in the form of an envelope around the fuel-oxygen jet from the pipes 3. The envelope may be given a whirling motion by vanes 7a which are set at an angle in the channel 6.
