Title: Improvements relating to machines for filling containers with liquid
Inventor: BAGNELLE ARTHUR HAROLD
IPC: B65B31/02
Filed: 1958-12-12
Abstract: 925,564. Filling-machines; filling containers. ALBRO FILLERS & ENGINEERING CO. Ltd. Feb. 19, 1960 [Dec. 12, 1958], No. 40193/58. Classes 94(1) and 125(2). A device enabling paper containers 9 to be filled with liquid by applying a sub-atmospheric pressure to the interior of the container comprises a filling nozzle 2 fitted with a shroud 6 that seats on a container lifting platform 7 to form an air tight chamber. A sub-atmospheric pressure applied to the chamber via a pipe 4 causes liquid to be drawn up a pipe 3 and into the bag 9, the filling action ceasing when the liquid level covers the lower end of the tube 2. The device is mounted on a rotary support and after each container 9 has been filled a spring loaded valve 12 on the shroud 6 passes a cam 13 whereby air is admitted to the shroud 6 to break the vacuum. By altering the thickness of a washer 11, between the filling head flange 5 and the shroud 6, the filling weight in the container 9 can be varied.

Title: Improvements in or relating to fluid pressure braking systems
Inventor: PARSONS DAVID
IPC: B60T8/42
Filed: 1968-08-22
Abstract: 1,272,935. Antiskid braking systems. AUTOMOTIVE PRODUCTS CO. Ltd. 15 Aug., 1969 [22 Aug., 1968], No. 40221/68. Heading F2F. In an antiskid fluid braking system in which the vehicle braking is dependent on vehicle deceleration and may also be dependent on the load, the wheel cylinders 17 are connected to a master cylinder 10 through a valve 13, the valve member 18 of which is unseated through a plunger 22 by the differential pressure across a diaphragm 27 which separates servomotor chambers 25, 26 being air and vacuum chambers respectively, air passing to chamber 25 through a first normally closed valve 30 opened on reception of a skid signal and a second normally open valve 31 having a closure member 32 coupled to a diaphragm 33 of a control device communicating on either side of diaphragm 33 with chambers 25, 26. On detection of a skid signal valve 30 opens, air passing to chamber 25 and diaphragm 27 and plunger 22 move rightwardly to close orifice 23 to reduce fluid pressure at the wheel cylinders 17. The differential pressure across diaphragm 33 also causes member 32 to close orifice 38 against the action of a biasing spring 39 and air pressure in chamber 25 is released through bleed passage 29 to release the brakes. A pivoted weight 41 is coupled to a rod 43 having a flange engaging a spring 44 which also engages a flange of a sleeve 45 and acts in opposition to spring 39. As the vehicle deceleration increases, weight 41 swings forward and the diaphragm 33 is forced downwards by rod 43 so that a lesser differential pressure is required to close port 38 and utlimately release the brakes. A bell crank 46 responsive to vehicle load is pivoted to the vehicle body at 47 and to an axle through an arm 49 and is coupled by a tension spring 50 to weight 41 so that an increased loading pivots arm 49 and restricts the swing of weight 41 through the spring 50, and therefore a higher differential pressure is necessary to close port 38. The weight 41 may be situated in a housing with a liquid to damp the movement of the weight.

As described the apparatus monitors a multi-row planter. For each row there is a dispensing drum assembly with a notched disc 43 which separates the seeds and is driven through gearing 46. Coupled to the gearing is an apertured plate 57 with a photocell 56 delivery pulses for each seed that should be delivered. At the end of each delivery tube 50 there is a further photocell delivering pulses for each seed. The two pulse trains for each row in turn are fed to an up-down counter via suitable dividers. When the count is zero a centre lamp is lit; when the count reaches first values one or other of the outer lamps is lit and when the count reaches second higher values the centre lamp is extinguished. In an automatic mode the row sensors are selected in turn automatically; a seven segment display indicates the last row selected and the lamps indicate the efficiency of the seed planting in that row. In a manual mode the rows are selected in turn when a manual switch is pushed; the display indicates the row selected and the lamps indicate the efficiency of planting in the selected row. If the actual number of seeds being planted in any one or more rows falls below a set level an alarm sounds and the display indicates the faulty row or shows zero if more than one row. The circuit (Figs. 4A, B, C not shown) includes switching for selecting the levels of which the lamps operate and for different numbers of rows (according to the planter).

In drafting-mechanism the top rolls are so mounted on a holding rail extending transversely to the bottom rolls below the drafting field that the positions of the top rolls can be adjusted relatively to the bottom rolls in the direction in which the sliver is fed. In preferred forms the top rolls are in pairs joined by a neck with bearing-rings 5<1>, Fig. 4 with a groove 5<11> between them, the weighting being magnetic. In Fig. 1, brackets 7 are secured by bolts 6 in chosen positions in slots marked with graduations in rails 3 located according to the positions of the drafting stations on a common rail 1. The brackets each have two webs 9, 10 supporting bearing members 11, those, 10, on the feed side being resilient, and those, 19, on the delivery side being rigid. The bearing members 11 support a top roll either by being shaped to engage over the rings and in the grooves or by means of rollers 12 Fig. 4. Members 11 may take the form of a spring with a finger engaging the groove 5<11>, and webs 9 may detachably support clearer rollers, flats or scrapers profiled to engage the rims and groove, or apronsupports with guide lugs and a tensioning-spring. In Fig. 16, the brackets are formed as feet 20 bent over to embrace the rail 3 and each carrying a web 21 supporting the roll by a spring bail 23, Fig. 13, and a dished bearing-member 22 or a spring lug 21<11> Fig. 16 engaging the groove 5.

[Also in Division F1] An apparatus for producing a pressurized mixture of gases comprises a container holding a pressurized refrigerant and having an outlet at one part thereof, a closure for sealing the outlet and arranged to rupture in response to a predetermined pressure within the container, a source of hot combustion gases at an opposed part of the container including a nozzle having an outlet bore facing the closure, and a plug slidably mounted in the bore having a lower end for engaging the closure to retain the plug in the bore and close the same until the closure is ruptured. A gas generator 10 for producing a pressurized mixture of gases to inflate an inflatable device comprises a spherical container 11 holding pressurized liquid carbon dioxide refrigerant with the possible addition of alcohol. An outlet assembly 12 including a frangible disc 17 is mounted at the bottom of container 11 and a chamber 18, containing a combustible charge 19 with an ignition squib 20 is mounted opposite outlet assembly 12. Upon ignition hot combustion gases flow from chamber 18 to rupture a frangible disc 29 before entering a nozzle member 21 having a throat 37. At this stage, a bore 41 in a tubular member 32 at the end of nozzle 21 is sealed by a plug 42 engaging frangible disc 17 so that the combustion gases flow through ports 38 at the nozzle throat 37 to vaporize and mix with the carbon dioxide and alcohol. When the pressure has built up sufficiently, disc 17 ruptures to release plug 42 and allow the combustion gases to discharge through bore 41, and the mixed gases to discharge through an annular gap 34 between a sleeve 22 and tubular member 32. The combustion gases flowing through nozzle 21 then entrain carbon dioxide flowing to the throat through ports 38. Either or both the bores 30 and 41 may be eccentrically disposed in relation to sleeve 22 and tubular member 32, respectively, so that by rotating the tubular member 32 or sleeve 22 about its axis the dimensions of the annular gap 34 can be made uniform. Container 11 may be cylindrical with hemispherical ends.
