Title: Improvements in or relating to machines for forming articles
IPC: C03B11/16
Filed: 1964-09-21
Abstract: <PICT:1073636/C1/1> <PICT:1073636/C1/2> An automatic machine for forming glass articles, wherein moulds are carried successively past working stations in a controlled sequence, has means for detecting the presence of an article remaining in a mould after passing the article take-out station and thereby causing the operation of subsequent working stations to cease when that mould passes through them while the machine as a whole continues to operate.  Mounted on the rim of the rotatable table 1 carrying the moulds and adjacent each mould is a cam 2 rotatable on a pivot 3, and a catch plate 4 rotatable on a pivot 5, the two being displaceable with relation to each other and either the high or low position held by notches 8 and 9 on the cam engaging stud 7 on the catch plate. A roller 6, located immediately after the take-out station I, Fig. 2, moves the cam 2 into its high position.  A piston-operated sensing member 18 dips into a mould and if it does not detect an article therein it opens a valve 21, causing an impulse to pass to a plunger 27 which moves the cam 2 to its low position.  If it detects an article remaining in the mould, the valve 21 remains closed and the cam 2 remains in its high position.  Thus as the mould passes each working station in turn with its cam 2 in its high position, impulses are transmitted to compressed air distributers 28, 42, 49 to cause the operations at those stations to cease, for example by deflecting the charge-delivery shoot 33 out of line with the mould, not lowering a press head 48, or not lowering a blow head.  Similarly at the article extraction station VII if the cam is in its high position, a valve operates a deflector plate to remove from a conveyer any article which has gone round more than once.  The automatic operations may be changed to manual operation.

Abstract: 1,072,328. Centrifugal separators; classifying granular materials. W. EIRICH and G. EIRICH. Sept. 23, 1964, No. 38867/64. Headings B2H and B2P. [Also in Division B5] A classifier comprises a rotatable dish 1, 2 from which particles of material of greater than a maximum predetermined size are discharged by being impelled from the dish by means of a toohed rotatable rake 16. The dish is operated in an inclined position and may be brought thereto by swinging it about a pivot 5 by means of a hydraulic cylinder 4, Fig. I (not shown). The dish is rotated by two motor gear reducers 6, 7, Fig. 3 (not shown). Rotating mixer blades driven by an electric motor 8 are provided. The motor 8 is mounted on an arm 9 which also supports a stationary cover having a sector-shaped discharge opening and carries a stationary pin 10. Mounted on the pin 10 is a vertically and angularly adjustable arm 12 on which a motor 14 and a reduction gear 15 which drive the rake 16 are radially and angularly adjustable. The motor 14 is reversible so that the rake may be used to act as a mixer if desired. The rake 16 has four rows of teeth which are made, for example, of thin steel wire, which may be coated with P.T.F.E. or rubber, so that they are flexed as they enter the material in the dish thereby being vibrated and kept free of incrustations. Vibration may be further imparted to the teeth by means of a stationary stop rail R which may be arranged obliquely to the rake centre line so that the teeth of any row will strike the rail successively. Material is fed into the dish by means of a pivotally suspended chute 19 passing through an opening in the cover 3 and having a dustproof connection therewith by means of a bellows 20. Spraying nozzles S are provided for assisting agglomeration of material in the dish. In operation, due to centrifugal action arising from rotation of the dish, the coarser particles are brought to the periphery of the dish and to the top of the material therein and are impelled out of the dish by the rake 16 and collected in a hopper 17 disposed above a conveyor 18. The size of the particles separated depend upon the vertical, radial and angular adjustments of the rake and on the speed at which it is rotated.

Title: Improvements in or relating to rotary wing parachute devices
IPC: F42B10/58
Filed: 1956-12-31
Abstract: 840,555. Rotary wing parachutes. GOTEX A. B. Dec. 31, 1956 [Dec. 31, 1955], No. 39639/56. Class 4. A rotary wing parachute device consisting of a plurality of blades adapted to be moved to a folded position in a launching device and arranged in such a manner that, after launching, the blades are swung out forming a bladed rotor is characterised in that the blades are resilient and foldable in the launching device against their resilient action and are adapted after launching, to swing out by their resiliency to form a bladed rotor. The embodiment described relates to a flare 6 launched from a rocket 5 and allowed to descend by means of the parachute 1 wherein the top of the flare casing 5 carries an extending pin 7 which supports a plate 8 formed with a frustro-conical surface 9. The rotor 1 comprises a plurality of thin steel blades of curved cross-section interconnected by pivots 2 offset from the lengthwise axis of each blade, so that the extended blades may seat under plate 8 as shown in Fig. 11. Each blade may be bent transversely away from its pivot 2 and then all blades rolled as shown in Fig. 10 to form a coil outside the surface 9 but within the diameter of flare 6. A split ring 4 is placed round the coiled blades and the assembly is inserted into the rocket casing 5. Upon ejection the resilience of the blades will discard ring 4 and the rotor will extend to its operating position shown in Fig. 11, in which it is loosely supported under plate 8 for rotation during descent. A further embodiment is described in which resilient blades are secured at their root ends to a rotary plate on the head of the flare by means of a spring ring and the blades, instead of being coiled are folded lengthwise against the outer surface of the flare for insertion into the rocket tube, the blades extending radially upon ejection of the flare.

Filed: 1963-10-08
Abstract: 1,005,846. Treating charge. MARVEL OIL CO. Inc. Oct. 8, 1963, No. 39685/63. Heading FIB. [Also in Division F2] In a device for metering a liquid, whose viscosity varies with temperature, to the intake of an I.C. engine, a flexible diaphragm 21 responds to suction of the engine which varies with the speed of the engine, so as to actuate a first element 40 of a valve; and a temperatureresponsive member 57 actuates a second element 59 of the valve. The diaphragm divides a housing 10 having a transparent cap 13 into chambers 23, 24, the upper chamber 23 containing the valve and communicating, via a bore 28 in the housing, with a coupling 27 leading to the intake manifold; the lower chamber 24 containing the liquid such as lubricant and being connected by a tube 32 with a tank 38. The liquid is transferred from the lower chamber 24 to the upper chamber 23 via a tube 41 which is carried by and passes through the diaphragm, the pressure differential causing the raising of the lubricant. The first valve element 40 is mounted on the tube 41 and includes a valve-seat 53. In operation, increases in the intake manifold vacuum cause the diaphragm 21 to flex upwardly so that the first valve element 40 moves towards the second valve element 59 to reduce the opening between the valve seat 53 and a valve needle 60. Conversely when the manifold vacuum decreases the valve opening increases. Additionally the changes of viscosity of the liquid caused by changes in temperature are compensated by the member 57 which bends when an increase of temperature occurs to bring the second valve element 59 towards the first valve element 40 so as to restrict the valve opening. Conversely a drop in temperature would increase the valve opening. The rate of flow is adjusted by a screw 58 mounted in the housing 10 and which rocks the member 57 about a fulcrum 56.
