Abstract: 811,119. Ampoules containing liquids under pressure. DISTILLERS CO. Ltd. April 11, 1957 [Feb. 3, 1956], No. 3408/56. Class 81 (1). A vessel, particularly an ampoule, containing liquid and gas under pressure in excess of atmospheric pressure comprises a sealed transparent container 3, Fig. 3, within which is a transparent tube 1 having a base of capillary dimensions, i.e. about 3.5 mm., one end of which is open to the interior of the container, the other end being sealed. The invention has particular application to glass ampoules containing injectable liquids under pressure that are designed to be adapted for use with hypodermic needles through a flexible tube 7. The purpose of the tube of capillary bore is to act as a pressure gauge, since when the ampoule is filled and the contents thereof subjected to pressure the liquid 2 will be forced into the capillary tube, the open end of which is in contact with the liquid. Any subsequent leak in the ampoule resulting in loss of pressure will manifest itself by a movement of the meniscus 5 within the capillary tube.

Title: Improvements in or relating to apparatus for forming ring or collar-like articles
Filed: 1956-02-07
Abstract: 825,845. Apparatus for making labelling collars. BARKER, F. A., CHAPMAN, V. F., and HINDSON, D. R. Feb. 6, 1957 [Feb. 7, 1956], No. 3735/56. Class 73 Relates to apparatus for forming paper blanks into a ring or collar like article for slipping on to the neck of a bottle. The apparatus comprises a mandrel 20 shaped similarly to the finished collar, a complementarily shaped die 26, means for feeding blanks to the mandrel means for causing axial movement of the mandrel relative to the die so that the leading edge of a blank engages the mandrel and then follows the shaped outer surface of it, the mandrel subsequently causing the die to be tilted about a transverse axis 51 until the blank is aligned with the mandrel and is contained between the mandrel and the die, means for joining the end of the blank to form a ring and means for separating the mandrel and die and stripping the formed article from the mandrel. The blank is a curved paper strip stored in one or more compartments (Fig. 8, not shown) on a magazine 22 which can be moved down by a hydraulic cylinder 23 (Fig. 1) until the blank contacts suction holes 113 on the upper surface of the mandrel 22 and is retained thereby after the magazine moves up again. The die 27 is normally urged by a spring 62 to tilt about an axis 51, but adjusts its alignment when the mandrel carrying the blank is moved into it by a hydraulic cylinder 21. The engagement of the mandrel in the die moves the latter into contact with a fastener mechanism 27 of which the cutting assembly is then moved by a spring operated plunger 64 through slots in the die to cut strips and tags in the ends of the blank 200 (Fig. 14) and to engage them together. The fastener mechanism comprises a fixed upper plate 73 (Fig. 4) having slits 74, 75 to pass U-shaped cutting blades 67, 68 and end slits 76, 77 to pass slitting blades 65, 66. Pivotally mounted within the U- shaped cutting blades are fingers 69, 70 each of which is urged towards the base of its associated cutting blade by springs 71, and 72 respectively so that the tabs that the U-shape cutting blades form in the end of the blank are folded over by the tips of the fingers into the corresponding strips that have been cut by the straight blades (Fig. 14). After the ends of the collar are joined the mandrel withdraws from the die and the collar is stripped from it by fingers at 106 into an open shoot 29 and to a position 122 to engage the neck of a bottle advancing on to it along a conveyer 121. (Fig. 10, not shown) illustrates diagrammatically the valves, pilot valves and ram cylinders that control hydraulically the sequence of operations.

Abstract: 1,272,735. Hydrostatic transmission control. SCHWERMASCHINENBAU " GEORGI " DIMITROFF MAGDEBURG-BUCKAU VEB. 27 Jan., 1970, No. 3912/70. Heading F2D. An hydraulic control system, e.g. for cranes, excavators &c., comprises a pump 1 feeding a pair of hydraulic motors 3 through selector valves 2 individually adjusted by duplicated controls including manual levers 28 operative on pressure valves 12 to direct fluid from an auxiliary pump 14 to opposite ends of valves 2 through lines 13, 27, the delivery and return lines 6, 9 from each valve 2 to its motor 3 including a braking valve 5 to throttle the motor output, and a piston-applied brake 8 being automatically released on driving the motor 3 forward or in reverse. The pump 1 may be of the axial-piston type and, as shown, the motors drive main and auxiliary lifting units 21, 22. To lift or lower the load 24, valves 2 are moved to charge line 6 or 9 respectively, to drive the motor and release the brake 8 through an " or " valve 7, interconnecting lines 6 and 9, and a check valve 10. On moving valves 2 back to their neutral positions, motors 3 stop and brakes 8 are reapplied gradually by spring force, the apply fluid being exhausted through a throttle in check valve 10. During lowering, the motor output is throttled by the braking valve 5 which begins to open at about 10 kp./ sq. cm., and is fully open at about 20 kp./sq. cm. The pump 1 output is controlled automatically by the pressure between the motor 3 and the braking valve 5 via an " or " valve 7 and a line 11. A manual servo override control 31 for the pump provides for an inching drive. Electrically actuated valves 16 receive signals from safety device (not further described) to connect the control lines 13, 27 to the return line 26 to move the valves 2 to neutral on overload, when the power is cut, or if the pump 14 fails, and an " and " valve 4 interconnecting lines 6 and 9 prevents release of brake 8 if an excessive pressure occurs in the return line 26.

Title: Improvements in mechanical time fuses for projectiles
IPC: F42C19/02
Filed: 1933-02-09
Abstract: 395,634. Projectile fuzes. SCHWOB FRRES ET CIE SOC. ANON., 134, Rue Numa-Droz, La Chaux-de-Fonds, Switzerland. Feb. 9, 1933, No. 4009. Convention date, Feb. 10, 1932. [Class 9 (i).] Relates to mechanical time fuzes of the kind in which the timing ring 2, to which the cap 3 is attached, is locked to the fuze body 1 by the set back of inertia members when the projectile is discharged, and consists in providing the fuze body 1 with a crown of ratchet-like teeth 13 and the ring 2 with a number of keys 15 formed with corresponding teeth and supported by springs, so that these keys set back during the acceleration period and interlock with the crown but are returned forward again by the springs after acceleration is over. This prevents an accidental shock before use causing a permanent locking which would prevent the operation of timing. The keys are staggered to ensure that the teeth of at least one of them shall be in line with the teeth of the crown. The ring 2 is gripped between resilient members 11, 12 by a nut 9 with the interposition of a washer 7 prevented from rotating by ears thereon in engagement with longitudinal notches in the collar 10 of the fuze body to which the nut 9 is screwed. This ensures a constant friction between the ring 2 and the fuze body 1.

Title: Improvements in power plant comprising a prime mover and an internal combustion compressor supplying motive fluid thereto
IPC: F02B3/06
Filed: 1944-03-07
Abstract: 595,627. Gas turbine plant. ENGLISH ELECTRIC CO., Ltd., and WELSH, R. J. March 7, 1944, No. 4191. [Class 135] [Also in Groups XXVI and XXVII] In a power plant comprising a gas turbine 18, or other prime mover, supplied with motive fluid by one or more internalcombustion, engine-driven compressors 1, the main supply of fluid is controlled by a speed governor 20, which also controls additional means to decrease or increase temporarily the energy input to the turbine during the time the governor is acting on the gas generator. The gas generator(s) may operate on the two-stroke compression ignition cycle, and the governor control the quantity of fuel injected per cycle. The additional means in Fig. 1 comprises a throttle valve 39 in the inlet manifold 17 and fuel injection mechanism 46, while a modification includes the valve 39 and a byepass valve for leading fluid directly from the manifold 17 to an intermediate stage of the turbine. The fuel pump 10 of each free-piston internal-combustion compressor 1 is regulated by moving a fuel rack 10a through governor action on a servo-motor valve 22 whose pistons control the supply of fluid under pressure to cylinders 24. Additionally, the governor acts through links 27, 28 and a servomotor valve 30 to control the position of a piston 33 which acts on a rod 35, to open or close the valve 39. A spring 38 acts on the valve bar 36. Excessive movement of the rod 35 upwards rocks a lever 40 over its deadcentre position, a spring 41 snapping together contacts 42. This causes an electric motor 43 to start up to drive a fuel pump 44 and supply fuel from a supply 45 to the injector 46 in the auxiliary combustion chamber 47. This increases the power of the turbine until the fuel supply to the gas generators is effective. In the second arrangement the auxiliary combustion chamber may be used, and in addition to the valve 39 the servomotor valve 30 controls the position of a byepaas valve which when open, allows fluid to flow from the manifold 17 to an intermediate stage of the turbine. A pipe 63 allows pressure fluid from 17 to act below a piston 61 to affect the governor setting. Other types of governor may be used, and may control the throttle at the inlet to the compressor as described in Specification 594,764, [Group XXVII]. Other means may be used to temporarily vary the input to the turbine.

[Class 102 (i)] [Also in Group XXIX] In the speed - regulation of a fuel injection pump by means involving the movement of a plunger 25 in a passage way 13 under the influence of liquid forced past the plunger by an auxiliary pump which also acts as a feed pump, delivering the liquid passing the plunger to the injection cylinder, the plunger and the body 12 forming the passageway are formed of materials having unequal temperature expansion coefficients, thus compensating for changes in viscosity. Alternatively, the stem 19 of the plunger may be formed with a higher expansion coefficient than that of the body. The passage and plunger may both be frusto-conical.
