Title: Actuation apparatus for the movable mould halves or parts of a moulding machine
IPC: B29C45/68
Filed: 1975-10-27
Abstract: 1512976 Mould actuating apparatus BUEHLER A G GEBR 27 Oct 1975 [28 Oct 1974] 44207/75 Heading B5A [Also in Division B3] A mould actuation device, for closing and opening an injection or die-casting mould 120, comprises a fixed toggle plate 3 connected by guide bars 5 to a fixed plate 4 carrying a first mould half. Slidable along the bars is a movable plate 2 carrying a second mould half. The movable plate is actuated through a cylinder operated head 15 connected by links 13 to four toggles 7 extending between the plates 2 and 3. Each toggle comprises a first lever 8, pivoted at a point 12 intermediate its ends to a link 13, and a second lever 10. The toggles are arranged in pairs, one either side of a vertical mid plane of the device passing through the longitudinal axis A. The toggles in each pair are actuated in parallel spaced planes, and the planes of one pair make an angle + α with the mid plane and the planes of the other pair make an angle - α with mid plane. Also the points of attachment of the toggle to the plates 2 and 3 lie at the corners of a square symmetrically located about the mid plane. The symmetrical location of the points of attachment enables a symmetrical closing and opening force to be applied without any bending moments and the spacing of the planes of actuation in each pair of toggles enables the toggles, in the mould open position, to be folded past the mid plane, this in turn enabling a large stroke H to be achieved.

Title: Improvements in or relating to lubricating systems for the bearings of rotary machines
Inventor: JONES GEORGE
IPC: F16N29/02
Filed: 1961-12-15
Abstract: 1,005,883. Lubricating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 2, 1962 [Dec. 15, 1961], No. 45030/61. Heading F2A. Lubricating means for a bearing comprises a forced-flow system and a secondary system which comes into operation upon failure of the forced-flow system. In an embodiment, a shaft 1, Figs. 1 and 2, is supported by a plain bearing having a splitbush 3, half-housings 4, 5, and inner and outer bearing caps 6, 7. The upper part of the bearing is enclosed by a half-cover 8 mounted on an end-bracket 2. The half-housing 5 and the cap 6 define a lower reservoir 9 and an upper reservoir 10 is formed in the half-housing 4. An oil pick-up disc 11, carried by the shaft 1, extends into the reservoir 9 and raises oil therefrom into a scoop 12 which supplies oil to the reservoir 10, from where it flows through passages 13 to the bearing surface and then returns to the reservoir 9. In order to prevent the disc 11, which is acting as the secondary system, from collecting oil from the reservoir 9, the level thereof is maintained below said disc by means of a passage 16 connected to a chamber 17. When the forced-feed system is in operation, pressurized oil enters at 15, Fig. 3, flows along a passage 14<SP>1</SP>, through apertures 25, 26 in a valve-body 19 and into a passage 14 which, together with the passage 13, connects with the bearing surface. The pressurized oil raises a piston 22, in the body 19, to expose the apertures 26 and to raise a valve 18, against the action of a spring 24, so as to allow passage of oil from the reservoir 9 through the passage 16 and into the chamber 17. As soon as the oil pressure is insufficient to maintain the piston 22 in its raised position, the piston descends thus covering the apertures 26 and closing the valve 18. The oil in the reservoir 9 can no longer escape, the level rises and the disc 11 effects lubrication of the bearing surface. A weir 28 retains a quantity of lubricant in the reservoir, an adjusting screw limits the movement of the piston 22 and a non-return valve (not shown) is positioned in the passage 13. The piston 22 may be replaced by a diaphragm.

Filed: 1964-11-23
Abstract: 1,022,437. Projectile fuzes. S. A. MEFINA. Nov. 23, 1964 [Feb. 7, 1964], No. 47497/64. Heading F3A. A clockwork fuze for rotated projectiles comprises plates 1-9 housing the clockwork mechanism and a primer carrier 12 pivoted on a spindle 13 between plates 1 and 2. Before launching the projectile, the carrier 12 is urged by a spring 14 to a position in which the primer 10 is out of alignment with a firing pin 15, while after launching a weight 16 on the carrier due to the centrifugal force causes the carrier to rotate into the armed position. Movement of the carrier is delayed by a bolt 17 until a toothed sector 18 housed in the plate 3 has rotated through a predetermined angle. Sector 18 carries a weight which under centrifugal force causes the sector to rotate. A collar 25 on the pin 15 bears on the edges of an arcuate slot in the sector. As the pin rides along the slot, a spring 27 abutting plate 5 holds the collar against the sector. The bolt 17 consists of an eccentric extension of the spindle 19 on which the sector is mounted, the extension having a flatted surface to free the carrier, when the sector has rotated through a predetermined angle. Sector 18 meshes with a spindle 29 carrying a gear-wheel 31 of a clockwork train 31-35, the escapement 35 of the train being regulated by a balance wheel 37. Balance wheel 37 is immobilized, as in Specification 688,883, by pins 43 depending from two arcuate levers 40 pivoted on the plate 9. When the projectile is fired from a rifled gun, centrifugal force causes the levers 40 to move away from each other and hence pins 43 release the balance wheel 47. The sector 18 also begins to rotate, its movement being regulated by the clockwork. When the sector 18 has moved through a predetermined angle, the bolt 17 releases the carrier 12, which then swings until the primer 10 is aligned with pin 15, a spring 45 then driving the primer into engagement with an opening 47 in the plate 1 to lock the primer in the armed position. When the sector reaches its final position, the pin 15 leaves the slot and the spring 27 drives the pin 15 against the primer 10. Reference has been directed by the Comptroller to Specification 688,883.

This reflector is positioned during a manufacturing test for optimum laser operation and is then secured to the prism by an optical cement havthe same refractive index. In each of the lasers described the resonator is formed by the combination of a concave mirror 2 and a plane mirror 8 located at the focus of the concave mirror as in Fig. 2. In this embodiment, the plane resonator mirror 8 is attached by optical cement 9 to a. Littrow prism 6 having its incident face 4 positioned at the Brewsters angle with respect to the optical axis 19 of a He-Ne discharge tube 1, the prism and a concave resonator mirror 2 being sealed to the tube by solder glass. Fig. 3 shows how the combination of a Littrow prism 12 and a totally-internally reflecting right prism 13 may provide the intermediate reflecting element in a folded gas laser comprising spaced tube arms 10, 11. A modified folded laser construction is shown in plan and section in Fig. 4, in which the two tube arms 30, 32 are adjacently positioned in a coaxial tube 34 which is itself surrounded by a shorter reservoir tube 36. An electrical discharge path between anodes 41, 42 and a cylindrical cathode coaxially mounted in the reservoir is provided by communication at C between the coaxial tube 34 and the interior of the tube arms 30, 32, and by ports 38 in the tube 34. Since the resonator provides a conical beam within the laser, uniformity of pumping in the two laser arms is obtained by grading the discharge currents between the respective anodes 41, 42 and the common cathode. In each case the incident face of the Littrow prism has a higher quality finish than the face to which a reflector is cemented.
