Title: Improvements in apparatus for filling valve bags with powdered or granular products
IPC: B65B1/18
Filed: 1931-03-17
Abstract: 373,696. Automatic-feed weighers. BATES INTERNATIONAL BAG CO., 48, Wall Street, New York, U.S.A. March 17, 1931, No. 8154. Convention date, March 17, 1930. [Class 143.] In a machine for filling valve bags with powdered &c. material, the material is received by the upper flight of an endless belt running at a speed such as to project it in an approximately horizontal stream into a spout which directs it into a bag. The material passes from a hopper through a shoot 52, rotary valve 53, spout 55, 56 on to a fast moving belt 57. This belt is formed trough-shape by a number of separate angle members 59, riveted thereto, which constrain the material, aided by air blast 81, to move with the belt, the material being projected through the nozzle 26 into the bag. The nozzle, Fig. 7, is open throughout the whole of its under surface, and is preferably provided with a sheathing member 101 forming two inverted channel sections, the air in the bag escaping through the channels 103. The bag is carried by a cradle 14, pivoted at 15 to a vertically movable frame 13 carried by the arm 10 of a weighing machine. Members 19 with handle 23 allow for the rocking of the cradle to lift off a filled bag. As the bag fills, it distends and rides upwardly over rollers 16 pivoted at 17, so that the weight is still taken by the cradle and not by the filling nozzle 26. When the charge has been run in, the frame 13 moves downwardly taking with it the nozzle 26, the feed still issuing being deflected by the shield 36 to a receiving bin. At the same time, the toggle system 31, 32, 33 is moved to lock the frame in the downward position, and a member 37 operates on a 3-way valve 39 to evacuate a pneumatic system 42, 43, thus allowing a gate valve 50 to be shut under spring influence 70. During the same downward movement of the toggle system, a gravity pawl 27, which normally retains the bag on the filling nozzle, is released so that the filled bag may be withdrawn by tilting the cradle 14. If the nozzle is choked by material inside the bag, the material being forced to it by the belt will be able to flow through the open bottom of the nozzle into a collecting bin below. The toggle system is unlocked by manual manipulation of the lever 33 and the gate valve 50 opened at the same time to fill a fresh bag. Alternatively to the angle plates 59, the belt may be ridged upwardly, and plates may be fixed to the member 60 to project downwardly to cover the ridges and thus confine the material.

Abstract: 992,421. Non-woven fibrous webs; paper making apparatus; paper. CHICOPEE MANUFACTURING CORPORATION. March 2, 1962 [March 2, 1961], No. 8188/62. Headings D1R, D2A and D2B. A non-woven fabric comprises a number of fabric areas 41, Fig. 8, in each of which there are a plurality of different fibre concentrations of which one is in the form of a thicker area portion 38 having heavy fibre concentration and others are thinner area portions 40 which, for an area size the some as the portion 38, have a lighter concentration, the densities of all the different fibre concentrations being substantially similar, and the portions 38 being spaced apart from each other but connected by the portions 40. A web 10, Fig. 1 formed of mechanically engaged fibres by carding, garnetting, air laying or paper making techniques is carried by a foraminous belt 11 around a cylindrical drum 14. The belt 11 passes around freely rotatable rollers 12, 23, 25 and a driven roller 24 and 15, in screen form, made of stainless steel, bronze, copper, alloy, nylon or acrylic fibrous material or is a punched sheet of steel or synthetic plastic. The drum 14 rests on portions 19 of flanges 20 preventing axial movement thereof and which are fixed on the ends of shafts 17 and is driven by the belt 11. A manifold 26 is supplied with a fluid, e.g. water, which is projected through nozzles 27 at the ends of tubes 28 arranged in banks, as shown, and through apertures in the drum to rearrange the fibres of the web 10. The moisture entrained in the web may be removed by a slotted chamber 21 connected to a vacuum source. The drum surface comprises protuberances 32, Figs. 7 and 9, one for each aperture 31 and which are directed towards the belt 11. The fluid funnels through the apertures 31 to form tubercles 38 interconnected by the portions 40. In a modification, not shown, the protuberances 32 face away from the web 10. In a further modification, also not shown, the belt 11, as well as the drum 14, comprises protuberances which face the web. The fibres of the web 10 may be cotton, flax, wood, silk, wool, jute, asbestos, ramie, rag, abaca, glass, viscose or cupra-ammonium rayon, ethyl cellulose, cellulose acetate, polyamide e.g. nylon, polyester, acrylic, polyethylene, polyvinylidene chloride, polyvinyl chloride, or polyurethane, alone or in combination with one another. A binder, e.g. an ethyl acrylate binder, may be applied to the web after fibre rearrangement by spraying, printing or immersion. Examples of web density, fibre length, fibre denier, percentage of binder and moisture content are given in the Specification. Specification 836,397 is referred to.

Title: Improvements relating to cleaning or filling mechanisms for containers
Inventor: FRIENDSHIP KENNETH FRANCIS MON
IPC: B65B39/14
Filed: 1962-02-02
Abstract: 971,808. Container cleaning and filling mechanisms. BURNETT & ROLFE Ltd. March 1, 1963 [Feb. 2, 1962], No. 8352/63. Divided out of 971,807. Heading B8T. A container cleaning and filling mechanism comprises a conveyer 1 for the containers, a cleaning and filling head 6, and a hoist, the head and hoist being arranged so that the head and a container raised by the hoist can move relatively to one another in all horizontal directions, and the head having a guide for engaging a container as it is raised to move the head and container into alignment. The hoist consists of a yoke 13, arms 14 and 15 pivoted thereto at 34 and 35 respectively, and a carriage 16 constrained for vertical movement only, and carrying rollers 17 and 18 just below the surface of the conveyer. The head 6 has a tubular extension 19 with a flange plate 20 attached by flanges to the base of a pneumatic cylinder 10, the ram of which is pivotally connected at 33 to the yoke 13 by a bracket 12. The head and pneumatic cylinder are slidable longitudinally of the conveyer on a tongue 23 attached to the fixed frame 24 of the mechanism, and are urged to a central position by springs 26, 27. A container to be filled is brought to the mechanism by an input conveyer 2 from which it is deflected by a bellcrank lever arm 3 on to the conveyer 1, which carries it to a position above the carriage 16 where it operates a trip lever 7 controlling a micro-switch 8 to operate the pneumatic ram and raise the hoist. The rollers 17, 18 are thus raised through the surface of the conveyer 1 to lift the container therefrom and allow it to move transversely thereof, so that its neck comes into contact with the bell-mouth 32 of the head. Movement of the head along the tongue 23 is made possible by the flexibility of arms 14 and 15, and slackness in pivotal joints 33, 34 and 35 and consequently the head and container move relatively to bring the container neck into alignment with the head, in which position steam and beer may be passed into the container successively via tubes 37 and 40 respectively. Specification 952,988 also is referred to.

Title: Improvements in or relating to electrochemical machining
Inventor: BROWN DENNIS COCKBURN
IPC: B23H3/04
Filed: 1961-03-08
Abstract: An electrode tool for the electrochemical machining of complex cavities consists of a <PICT:1012161/C6-C7/1> <PICT:1012161/C6-C7/2> <PICT:1012161/C6-C7/3> plurality of rods, tubes, sheets or plates 1 secured together in a bundle or stack with their ends defining a working face of the required shape of the cavity.  A plurality of tubes 1 are assembled with their ends abutting a master die 2, which may be a lead casting, and are then soldered together.  The ends are then shaped to conform with the die surface by electrochemical machining using the die as the cathode.  During use of the tool in electrochemical machining, the electrolyte may be supplied to the working surface through some of the tubes and be exhausted through adjacent tubes, Fig. 4 (not shown), or the tubes may comprise concentric inner and outer tubes whereby the electrolyte may be supplied through the inner tube and exhausted through the annular space or vice versa, Fig. 3 (not shown).  The tubes may provide a hydraulic impedance to the flow of electrolyte so that any change in back pressure at the working surface is always less than the pressure drop in the tubes.  The electrolyte is recirculated after filtration. In another embodiment, Fig. 5 (not shown), the electrode comprises a set of helical tubes nested together with longitudinal grooves cut in their corners to form passages for the electrolyte.  In another embodiment, Fig. 6 (not shown), the tubes may be of stainless steel and have external fins or they may pass through spaced apertures in a plate.  In a further embodiment, Fig. 7 (not shown), the electrode consists of an assembly of sheets formed with longitudinal grooves for the electrolyte. During machining the current flow may be monitored by a probe 12, Fig. 8, passing through the electrode 11; alternatively the probe may pass through one of the tubes forming the electrode.  The gap between the electrode and work may be maintained constant by controlling the feed rate of the electrode so as to maintain the monitored current constant. Alternatively the gap may be maintained constant by maintaining constant the electrode feed, supply voltage and electrolyte temperature. Electrolyte is recirculated and filtered.  A specific example is given for machining a particular Cr-Co-Ni-Al-Mo alloy using an electrolyte of sodium chloride and hydrochloric acid in water.

Title: Improvements in or relating to photographic cameras
IPC: G03B9/26
Filed: 1946-03-20
Abstract: 609,868. Photographic camera shutters. KODAK, Ltd. March 20, 1946, No. 8597. Convention date, March 27, 1945. [Class 98 (i)] A shutter comprises an apertured supporting plate on opposite sides of which are pivoted an apertured shutter blade and a cover blade, a hairpin spring attached between the shutter blade and the cover blade, a trigger which is operated against spring action to move the cover blade, and a rebound control device actuated by the movement of the cover blade to engage a member carried by the shutter blade when this is in predetermined positions. As shown, the shutter blade 5 having a reniform aperture 6 is pivoted at 7 on one side of the supporting plate 1 provided with an exposure aperture 2, while the cover blade 22 is pivoted at 23 on the other side of this plate, the two blades being connected by a hairpin spring 18 attached to a pin 20 on the cover blade and a pin 15 on the shutter blade projecting through a slot 16 in the supporting plate. A trigger 25, which is slidably supported by lugs 27, 28 on a bracket 26 and is movable against a spring 29 disposed between the lug 28 and a shoulder 30 on the trigger, carries a pin 24<1> which engages a hole in the arm 21 of the cover blade and also a slotted end 33 of an arm of the rebound control lever 31 pivoted at 32. On depressing the trigger, the end 37 of one of the lateral spring arms 34 of this lever is moved out of, and the end 35 moved into, the path of the pin 15, and the cover blade is rotated to uncover the aperture 2 in the plate 1, and in so doing doubles up the hairpin spring. When this spring has passed the centre line between the blade pivot 7 and the pin 15, the shutter blade is caused to rotate anti-clockwise making the exposure. The ends of the arms 34 of the lever 31 are bent towards the slot 16 and have a braking effect on the shutter blade by way of the pin 15 as this approaches the end of the slot, and finally abut against the flat end 37 of the pin, thus preventing the blade from bouncing. The pin 15 being held, the spring 18 returns the cover blade to close the exposure aperture, and on releasing the trigger the blade returns to its rest position again, freeing the pin 15 from the latch 35 and tensioning the spring 18, which then returns the shutter blade to rest. For bulb exposures, a lug 8 on the shutter blade is engaged by a detent on a lever which may be set in the path of the lug to hold the aperture 5 in register with the exposure aperture 2 so long as the trigger is depressed. In a modification of the shutter, the cover blade comprises an apertured plate and the spring arms of the rebound control lever are arranged perpendicular to the plane of the,lever.

Filed: 1972-02-24
Abstract: 1371946 I C engines - fuel control ALFA ROMEO SpA 24 Feb 1972 [24 Feb 1971] 8706/72 Heading F1B [Also in Division G1] The invention relates to an arrangement for regulating the amount of injected fuel for injection systems of I.C. engines. The system comprises a three-dimensional cam 1 and a follower 4, the cam being mounted on a shaft 2 which is movable axially in dependence on engine speed and rotationally in dependence on angular position of the throttles 61, 62, 63, 64, the axial position of the cam follower 4 being sensed by a mechanical/electrical transducer 7 the electric signal from which is passed through a processor 77 which transmits signals to the windings 38, 39, 40, 41 of the fuel injection devices 34, 35, 36, 37, The system comprises a mechanical/electrical transducer 82 connected to the engine shaft, the electrical output signal 84 being passed to a comparison means 85 from which an error signal 87 passes through distribution means 88 from which a signal passes either through line 89 or line 90 to an electrical/mechanical transducer 91, the mechanical output signal 92 from which is amplified at 93, the mechanical signal 72 being transmitted to the device 71 which is the three-dimensional cam and follower 1, 4, the speed signal 72 acting to produce axial movement of the shaft 2 and cam 1. The mechanical signal 73 is the signal representing angular position of the throttle members 61, 62, 63, 64 and is communicated through gearing 11, 10 to produce angular movement of the shaft 2 and cam 1. The resulting axial position of the cam follower 4 is sensed by the mechanical/electrical transducer 75 in the form of a potentiometer 7 and the signal 76 is transmitted through the processor 77 to the windings of the fuel injectors 34, 35, 36, 37. Axial movement of the shaft 2 and cam 1 is produced by means of a link 14 pivotally mounted at 15 and bearing at 13 against the end of the shaft 2. The diaphragm 19 of a pressure capsule 21 is connected through pin 17 to a point 17 on the link, and the diaphragm 18 of a pressure capsule 21 is connected through pin 16 to a point 16' on the rod. The pressure capsule 21 is open either through valve 42 or valve 47 to pressure in line 23 or to pressure in line 48 depending on whether current is flowing to coil 49 or coil 50, i.e. whether current is passing through line 89 or line 90, Fig. 1. The pressure capsule 20 is always connected through line 22 to pressure in line 24 and acts as a constant biasing force. The angular position of the shaft 2 and cam 1 may alter-  natively be dependent on suction pressure in the intake manifold.
