Title: Device for dispensing a fluid substance and more particularly melted cheese
IPC: B65B3/32
Filed: 1970-12-01
Abstract: 1309770 Packaging fluid substances FROMAGERIES BEL-LA VACHE QUI RIT 1 Dec 1970 [4 Dec 1969] 57029/70 Heading B8C [Also in Division F1] A device for simultaneously dispensing measured quantities of a fluid substance, such as melted cheese, into a plurality of containers 6 advancing intermittently along parallel lines, comprises a tank 11 for the substance with as many orifices in its bottom leading to passages 21 as there are containers to be filled, and dosing means 9 below the passages 21 with outlets 41 leading into conduits 53 to which vertically movable discharge nozzles 55 are secured. A dosing unit 2, a cam-box unit 3, and a drive take-off and release unit 4 are releasably attached to each other through screwdriver and slot driving connections. Cams 64, 65, 66 and 67 rotate on a shaft 62 and actuate the dosing and pouring mechanisms. Rotatable sleeves 24 have passages 25 which may be aligned with the passages 21 to allow pistons 44, driven by compressed air jack 97 through push-bars 45 on rod 48, to draw the measured amount of substance into passages 40 and then, after sleeves 24 have closed passages 21, to discharge that amount through outlets 41. Similar rotary sleeves 42 in discharge sections 10 have conduits 53 which are aligned with outlets 41 for discharge. The rod 48 follows the profile of eccentric cam 65 under the pressure of jack 97. Air is supplied to jack 97 through pipe 99 via a slide-valve controlled by cam 66. The amount of substance drawn in by pistons 44 is adjustable during operation by external knob 111 which adjusts the axial position of a piston 103 between jack ram 98 and rod 48 to limit the stroke of the rod 48. Adjustment with the device at rest is performed by manual rotation of bushes 112 between pistons 44 and push-bars 45. Sleeves 24 and 42 are actuated by cams 64 and 67 with followers 70, 71 carried on levers 72, 73 which control gear trains 78a-78d and 79a- 79d driving the sleeves 42 and 24. Unit 4 may be disengaged from driving engagement at 130, 131 with unit 3 to permit washing of units through ducts provided independently of other devices driven by shaft 126.

Abstract: 1419255 Forging J-B P VAU 11 Dec 1972 [13 Dec 1971] 57041/72 Heading B3H  A sheet metal blank is formed and stress relieved by forging a metal blank 1a between a die 3 and a punch 4 which define a cavity in their closed position, the blank projecting from at least one end of the cavity so that the blank can be upset by punches 5, Fig. 7, after forging so as to accurately fill the cavity. The initial blank is larger by between 1 and 10% than the length of the final article and after forging but before upsetting the width and thickness of the forged blank are smaller than those required in the final article. There may be a set of dies 3a-3c, Fig. 1, and a set of punches 4a-4c, if the article is extremely long. The die and punch parts are slightly spaced by springs and move together when abutted by the upsetting punches 5. The punches may have a reduced leading portion 21, Fig. 13, of the die has a greater length than the blank so as to contact the end of the blank for upsetting. The die and punch may co-operate to trim the blank before upsetting. The formed article is a turbine blade.

Abstract: 1,210,686. Nuclear power plants. GENERAL ELECTRIC CO. 19 Dec., 1967 [11 Jan., 1967]. No. 57644/67. Heading G6C.  In a steam cooled, fast nuclear reactor, superheated steam from the reactor is supplied to a turbine after the removal of radioactive contamination. Superheated steam passes from the reactor 10 through line 36 to the steam generator 14 where desuperheating of the steam and evaporation of water 40 occurs. Saturated steam is pumped from 14 by circulator 16 to the reactor coolant inlet. A minor fraction of the steam from 14 is urged through line 64, is superheated in the heat excharger 12 by the reactor coolant, and is passed to the turbine 20 through line 54. The contamination from the reactor core is retained in the water 40 and is removed by filtration and ion-excharge. The annulus 150, Fig. 2, is filled with water and steel rods 152 to form a shield round the core 28, the water flow rate being controlled to prevent boiling. The core has a central fuel region surrounded by a reflector and each vertical fuel rod consists of an upper void region, upper and lower reflectors and a central fuel zone.

Apparatus for delivering bricks from a brick making machine, wherein a conveyer movable stepwise through a closed path in timed relation with the rate of issue of bricks from the brickmaking machine is provided with brick receivers mounted at predetermined intervals on the conveyer for movement therewith, each receiver having two brick supporting elements disposed at right angles to one another, whereby each brick receiver is moved in turn by the conveyer to a position at which one brick supporting element is disposed to receive a brick face downwards thereon and the receiver and a brick disposed thereon are turned by further movement of the conveyer so that brick is supported edgewise by said other of the brick supporting elements to facilitate manual removal of the brick from the conveyer. As shown, bricks pass from a press machine 14 to a table 15 from which they are fed by a plunger 22 to a conveyer. This conveyer comprises a pair of endless chains 17 passing round sprockets 18 and carrying receivers 19 consisting of supporting elements 20, 21, the elements 21 being attached to the chains 17. After a brick 12 has been pushed edgewise into a receiver on to its element 20, the conveyer is moved to bring the next receiver into brick receiving position and during the successive movements of the chains 17, the receivers 19 and bricks 12 supported thereby are turned,so that they move along the upper run of the conveyer and the bricks are supported endwise by the elements 21. Each element 20 is preferably provided with an aperture whereby an operator's hand can span the upper edge of a brick and the fingers and thumb can grip the opposite faces of the brick to facilitate removal thereof. Alternatively, the elements 20 are dimensioned as shown so that the bricks when supported by the elements 21 project above the upper edge of the elements 20 whereby the upper parts of the bricks are.free to be grasped by the operator. A plunger operated in timed relation with the conveyer may be provided to remove bricks from the delivery end of the conveyer should the operator have not previously removed the bricks manually.

A pointer k on the member d is movable with the member d when the compressed length of the spring e is altered by suitable screw means acting on the member d. The pointer k indicates on a scale m at what fluid pressure the spindle f will advance or recede to operate at its free end electrical or mechanical members for giving an alarm or for excersing a control. A pivoted plate w is shown for indicating when the alarm is operating or when the alarm has operated. Thus if the pressure on the diaphragm falls to a predetermined value, the spindle f rises and compressed air from a source y is permitted to pass the ball valve q to a bore x and thence to act on a piston t to cause the pivoted plate w to be lifted. The hinged plate w must be manually reset. Specifications 435,133 and 650,290 are referred to.
