Title: Thread winding machine
IPC: B65H54/28
Filed: 1964-08-04
Abstract: 1,080,721. Winding yarns. MAREMONI CORPORATION. Aug. 4, 1964 [July 29 1963], No. 31177/64. Heading D1J. The thread winding machine is rendered compact by arranging the driving motor 30, the spindle 22 for supporting the package core 24, and the means 36 for reciprocating the thread guide assembly 26, in side-by-side relationship, from a housing 40 for a gainer mechanism 98, 104, 106, 122 ensuring that coils on the cross wound package are in close relationship. The housing 40 also contains a belt drive 52 from the motor 30 to the spindle 22. The reciprocating means includes a grooved cylinder in a protective housing 152, the housing having an elongated opening through which a cam follower on the thread guide assembly 26 can extend to engage with said groove. The elongated opening is protected by a dust cover such as a slitted plastic or rubber membrane 184 that is pushed aside by the cam follower as it reciprocates. The cam follower 26 slides on a bar 192 and includes a thread guiding arm 198 that bears against the package being wound and is rockable about the bar 192. The cam follower 26 includes spring means for biassing the arm 198 against the package, the spring means being manually adjustable to vary said biassing force. Preferably the diameter of the grooved cylinder when multiplied by the number of revolutions that it makes for each traverse of the follower 26 is substantially equal to the length of the cylinder.

Title: Procedure for providing a shaft lining of concrete
IPC: E21D5/12
Filed: 1958-09-30
Abstract: 840,875. Shuttering for concrete mine shaft lining. LAEVEN N. V., J. H. Sept. 30, 1958 [Oct. 16, 1957], No. 31242/58. Class 20(2) A concrete shaft lining is constructed in sections from the top downwards, and each section is constructed from the bottom upwards by the use of a sliding mould which can be moved up cables suspended from a frame fixed, by radial expansion, in a section previously constructed. A frame 7 (Fig. 1) is lowered into a shaft by the normal hoist gear and is expanded against the walls of the shaft by hydraulic jacks 8. Suspended from the frame 7 by rods or cables is a mould 5, consisting of alternate segments 15 (Fig. 5) and conical members 16, and which can be dis-engaged from the shaft walls by retracting the members 16. Connected to the mould by hydraulic jacks 21 is a supporting ring 22 to which is attached a working floor 24. Both the mould and the supporting ring are fitted with clamps 23 (Fig. 10) which are self-locking if the members move down, but which can be rendered inoperative by a handwheel 30. With the mould at the bottom of the cables conical segments 34 are fitted between the lower edge of the mould and a radial recess in the shaft wall and concrete is placed into the annulus between the mould and the shaft wall. The mould is then moved up in stages by admitting fluid under the piston 32 (Fig. 10) to raise the mould and over the piston to lift the supporting ring. When the mould reaches the top of the cables it is disengaged from the shaft walls and the whole apparatus is lowered by the hoist gear 10 until the frame 7 is near the bottom of the last-completed section. The frame 7 is then expanded to fix it in the shaft, the hoisting gear is disconnected from the frame and connected to the mould, and the mould and supporting ring are lowered to the bottom of the cables, the clamps 30 having previously been rendered inoperative. The hoist 10 is then raised and reconnected to the frame 7.

Filed: 1974-07-16
Abstract: 1456883 Gyroscope caging FERRANTI Ltd 14 July 1975 [16 July 1974] 31372/74 Heading G1C A floated gyroscope comprises a rotor within a container 10, a housing 14 for the container 10, and a locating member, in the form of a pin 26 and co-operating limit means in the form of a pair of arms positioned on either side of the pin 26 mounted one on the housing and one on the container, wherein the limit means is operable to restrict the angular movement of the container 10 when the gyroscope is not in use to less than its operational range. Viscous liquid is contained in the space between the housing 14 and the container 10, and as described, the temperature thereof is maintained at anelevated level. Thus the limit means which is situated within the liquid, and mounted either on the housing 14, as shown or on the container 10, is hotter during gyroscope operation. The limit means may comprise bi-metallic elements 24 which, when the gyroscope is not in use abut a pin 23 of the locating member so as to restrict the possible movement of a smaller diameter pin 26 which is mounted on the other of the container 10 or housing 14, so as to restrict the container 10 movement. During use, the bi-metallic elements 24 move apart so as to define a large range of allowable movement for the pin 26 and hence the container 10. The limit means may comprise resilient arms which are biased to abut pin 23 but which, by movement of a wedge therebetween may be expanded. The movement of the wedge may be effected by an electromagnet (28) Figs. 4 and 5, (not shown) or a lever-operated mechanical linkage. When an electromagnet is employed it may be energized from the same supply as the gyro-motor so as to act as a fail safe device. The limit means are mounted on a support in a position such that during non operation of the gyroscope the position of the container 10 is at or adjacent the null position.

Abstract: 231,240. Kilburn, B. E. D., (Sulzer FrÞres Soc. Anon.). Dec. 29, 1923. Refrigerating, absorption machines and processes for.-The evapotator is shaped so as to prevent mixture therein of the liquefied refrigerant with the liquid absorbent carried over from t.he generator, and the liquid absorbent is automatically fed back to the absorber or to the return strong liquor passage by the weight of the liquid column of refrigerant in the evaporator. The arrangement may be applied to reversing and continuous cycle systems. In a reversing svstem comprising a generatorabsorber 1, Fig. 1, a condenser 2, and evaporator 3, the evaporator preferably comprises an upper vessel 10 for vapour and a lower vessel 9 for liquid, connected by a restricted passage 11. A bye-pass pipe 8 connects a well 12 at the bottom of the vessel 9 with the return vapour or suction pipe 7, and may be formed as a siphon 13 to stop the return of absorbent when the liquid in the evaporator reaches the level of the connection 14 on the pipe 7. Or a passage 15 opening into the evaporator at a higher level 16 may be employed to limit the return flow of liquor. The passage 8 may connect with a pipe serving both as a pressure and suction or return vapour passage for a reversing system having control valves. The evaporator may comprise two lower liquid containing vessels 9, Fig. 4, connected to an upper gas chamber 10, the vessels 9 having wells 12 fitted with pipes 8, leading into the common suction pipe 7. The evaporator 1, Fig. 5, of a continuous system may be divided up into chambers 4-8 communicating with one another through passages 9-12, the refrigerant being conveyed from the condenser to the first chamber 4 through a pipe 2 with expansion valve 3. The weakest liquid, i.e. that containing most absorbent, accumulates in the last chamber 8 and is fed by a pipe 13 to the pipe 15 through which strong liquor is delivered from the absorber 14 to the generator by a pump 16. The absorber is connected with all the chambers 4-8 by a common pipe 17. In a modification, the evaporator and absorber may each be divided into independent chambers, in which case the chamber 8 of the evaporator containing the bulk of the absorbent is connected to the absorber compartment containing the weakest liquor.
