Filed: 1947-10-31
Abstract: 655,309. Machines for making glass ampoules. GUSTI, A. Oct. 31, 1947, No. 29173. Convention date, Oct. 31, 1946. [Class 56] In a semi-automatic machine for making phials from glass tubes, of the general type described for example in Specification 364,211, the gas burners supporting disc 1 may be displaced vertically, while the machine is working, by means of a rod 4 running inside the bore of its driving shaft 2 in order to vary the cramping point of the phials. The rod 4 is joined by bolts 5 to coupling boxes 6 between which is a boss 1#a of the disc 1, and at the lower end has a threaded engagement with a pinion 7 which, by means of the ring 8, rotates about the shaft 2 without axial displacement. The pinion 7 is engaged by a second pinion 7a which is joined to the hand wheel 9, so that by turning wheel 9 the rod 4 thence the burners 39 on disc 1 may be adjusted vertically. The lower pincers 12 are displaced by columns 11 which stand on a cam gear 10 fitted with three vertical threaded bars 13. These bars engage in toothed wheels 15 on the platform 14, so that they cannot rotate against the wheels but are displaceable axially. The pinions 15 are joined by chains 16 to a driving wheel 17 which leads by means of the shaft 18, the orthogonal pair of wheels 19, and the hollow shaft 20 to the hand wheel 21, so that by turning the latter the cam gear 10 may be adjusted vertically to vary the length of the phials. The machine gear 22 and spring 24 are enclosed in a casing 23 as a protection against glass splinters, and similarly a casing 26 protects the gear 25 and spring 27. The shaft 28, in which gears 25 run, is enclosed in a casing 29, and the drive gear 30, pinions 31, 32, and gas distributer 33 are enclosed in the casing 34, 35, while the worm with the worm wheel 36 and conical wheel 37 run in an oil bath in the casing 38.

Patent GB-1032779-A (GB)
Title: Method of preparing uranium dioxide fuel compacts
IPC: G21C3/62
Filed: 1964-07-15
Abstract: Sintered uranium dioxide compacts are prepared by intimately mixing highly sinterable UO2 at a proportion of 1 to 10 weight per cent with finely divided high-fired UO2 of low sinterability, compressing the resulting mixture into compacts at a pressure of at least 20,000 p.s.i. and sintering the compacts in a reducing atmosphere.  The compacts into which the UO2 mixture is compressed have sufficient strength for handling without an added binder so that contamination from this source is avoided.  This mixture sinters to a high density of over 95% theoretical with minimized shrinkage and distortion. The term "highly sinterable UO2" refers to UO2 powder which sinters to a density of at least 10.5 g./c.c. upon being compressed at a pressure of at least 10,000 p.s.i. and heated to a temperature of 1400 DEG  C. for at least 2 hours under a reducing atmosphere.  The term "high-fired OU2 of low sinterability" refers to OU2 fired to a temperature of at least 1000 DEG  C. in a reducing atmosphere or at least 1600 DEG  C. in an inert atmosphere during or subsequent to its preparation.  This treatment serves to densify the OU2 particles and to decrease the surface area and sinterability.  Methods of production and the physical properties of the two types of UO2 are described.  The sintering is effected at a temperature of at least 1700 DEG  C., preferably 1900 DEG  C., for a period of at least 4 hours.  The compacts undergo a shrinkage of about 12 to 13 vol. per cent under typical conditions, and this shrinkage is taken into account in sizing the compacts.

Title: Apparatus for the delivery of feedstuff to a feeding station
IPC: A01K5/02
Filed: 1971-06-23
Abstract: 1331392 Feeding animals SCHMEING Gebr 23 June 1971 [24 June 1970 10 Feb 1971] 29424/71 Heading AIM [Also in Division B8] For delivering feedstuff into a feeding trough 2, a container 7 has a pusher 16 which is reciprocated across a base plate by a cable 19, the plate in combination with end walls 9, 10 providing discharge apertures 11, 12. A pipe 5 extending into the container 7 is connected to a main pipe 4 and is adjustable between the position shown in Fig. 3 and a position on the other side of the container 7, substantially above the path of the pusher 16. If the pipe 5 is maintained in the Fig. 3 position no feedstuff is engaged by the pusher but in the other extreme position there will be full discharge from the pipe in the path of the pusher and out of the apertures 11, 12. At intermediate points as indicated by a scale 21 on a panel 15, there will be corresponding rates of discharge. A number of stalls 1 are provided with the main pipe 4 and the cable 19 being common. In a modification, Fig. 4, the pipe 5 discharges into an inner compartment 25 of which the bottom opening is variable by a manually adjustable plate 26. To minimise "bridging" of feedstuff a plate 34 forming one wall of the compartment 25 is slidably mounted on a wall 13 of the container. Toward the ends of its reciprocating motion the pusher 16 engages projections 37 on the plate 34 which is thus given limited movement. A rod 19 operates the pusher.

Title: Improvements in or relating to snap action electric switches
IPC: H01H5/18
Filed: 1936-10-29
Abstract: 486,116. Electromagnetic interrupters; snap action switches; transformers. BURGESS LABORATORIES, Inc., C. F. Oct. 29, 1936, No. 29478. Convention date, Dec. 4, 1935. [Class 38 (v)] [Also in Group XXXV] An interrupter which may be used in an induction coil to give a series of flashes in a neon tube, say every two seconds, comprises an actuating member such as an armature 232 having a natural period of vibration and adapted to carry the end 248 of a compression spring 244 over dead-centres relatively to a tension strip 238 to which the spring 244 is connected at 242. In the form shown, the common ends of the members 244 and 238 carry a contact 246 which engages a contact 250 and closes the circuit to the primary 220 of the induction coil. The armature 232 is thus attracted, moves the point 248 downwards beyond the strip 238 so that this snaps upwards carrying the contact 246 away from the contact 250. This breaks the primary circuit and causes a flash in the neon tube energized by the secondary. The armature now returns to its original position and the contact snaps back into the closed position in a similar manner. Owing to the inertia of the armature, however, it goes beyond the original position and for a short time oscillates to and fro with decreasing amplitude during which time by engaging. the spring 244 which acts as a bumper, the contact 246 is periodically lifted off the contact 250. The dead-centre position is not passed during this oscillation and the frequency of break is such that no bright flash is produced in the neon tube, but, in some cases, a series of dim flashes which merge into a continuous glow. When the contacts 246, 250 engage each other long enough for a full energization of the magnet 220, the armature 232 is again attracted down to move the point 248 over the dead-centre position, with a snapping over of the contact 246 and a bright flash in the neon tube. Specification 419,917 is referred to. The Specification as open to inspection under Sect. 91 also describes a number of forms of snap-action switches all having the feature of a tension member 16, Fig. 1 (Cancelled), connected at one end 24 to a compression member 22 and the two other ends of the member being relatively movable so that the mounting point of the compression member crosses the line of the tension member to cause a quick action. The form shown in Fig. 1 (Cancelled) is operated thermally by a bimetallic strip 12. Fig. 3 (Cancelled) shows a form operated off and on by respective depression of two push-buttons 58, 62. Fig. 11 (Cancelled) shows a switch electromagnetically operated. This subjectmatter does not appear in the Specification as accepted.
