Title: Improvements in or relating to stirring and heat transfer devices
IPC: C13B30/02
Filed: 1947-08-26
Abstract: 629,988. Mixing appliances. JENNINGS, H. W. K. (Western States Machine Co.). Aug, 26, 1947, No. 23574. [Class 86] [Also in Groups XXVI and XXXIV] A mingler for mixing massecuites comprises a tank 10 provided with a rotary heat-transferring stirrer coil 12, mounted near the bottom of the tank in bearings 13, 21 in the end walls which allow lateral and angular deflection of the stirrer. The stirrer coils 12 are mounted on a tube 11 and open into it at opposite ends. The tube 11 is divided by a partition 24, Fig 2, near one end into chambers 23, 28. Hot water is fed into chamber 28 by a tube 26 which is welded to the partition 24 and is in communication with the inlet 18. The hot water leaves the tube 11 through outlet 80, Fig. 3, into the end coil 79 of the stirrer coil 12 and passes back to enter the chamber 23 in the tube 11, from whence it flows along the annular spaces between inlet tube 26 and a coaxial tube 30 secured to the end of the tube 11, to the outlet 19. Owing to the viscosity of the massecuite there is a tendency for the stirrer coil to bend, and the bearings are therefore constructed to allow for deformation without destroying the seal. As shown in Fig. 2, the stirrer coil is rotated by a sprocket 14 secured to the tube 30. The tube 30 rotates freely in the distribution box 20 to which the inlet 18 and outlet 19 are connected; and also in a roller bearing 64 secured to the side wall of the mingler tank. A spring 41 engages a flange of the roller bearing and presses on a packing follower 48 and urges it into cooperation with packing rings 49 and a packing retaining ring 51. Ring 51 is held in place by a rotating collar 54. A pin 53<SP>1</SP> in the bushing 53 prevents ring 51 from rotating, and owing to the clearance 48a between follower 48 and bushing 53, and clearance 51a between ring 51 and bushing 53, the ring 51 is allowed to undergo angular movement  and also axial movement is taken up by spring 41. Roller bearing 64 may be replaced by a self aligning roller bearing. At the other end, Fig. 3, the tube 11 is mounted by means of a stub shaft 74 in the bearing 21. The bearing consists of a housing having two opposed conical bearing surfaces 60, 61 and a bearing sleeve 66 fitted rotatably on the shaft 74. Sleeve 66 has spherical bearing surfaces 67, 68 which engage the surfaces 60, 61 to form a sealed and angularly adjustable bearing. In operation, the heat of the stirrer coils is controlled by thermostats situated in the outlets from the mixer, and in the hot water reservoir. The bearing 21 may be mounted just inside the mingler tank instead of in the end wall. Specification 455,554, [Group VI], and U.S.A. Specification 2,128,873 are referred to.

Filed: 1921-09-05
Abstract: 182,365. Craig, C. F. Sept.. 5, 1921. Golf-practising appliances.-A captive ball device for practising golf &c. comprises a standard, a revoluble sleeve thereon, a rod carried by the sleeve in spaced relation thereto and extending from end to end thereof, a ball tethered to the rod by a connection which slides freely on the rod, and means for indicating the distance the ball would have travelled if free. The device rests on a base 1 into which a standard 7 is fitted, a cushion 3 being interposed between the base and the standard. Revolubly mounted on the standard is a sleeve 8 carrying a rod 16 to which a ball 19 is tethered by a sliding member 21. The rod 16 is bent partly to reduce rigidity and partly to bring the initial position of rest of the slide 21 to a low level. A dial 24 is mounted on the standard 7. When the ball is struck the sleeve 8 is caused to revolve and the ball moves up the rod 16 towards the position shown by dotted' lines, the movement being steadied by the centrifugal action of a spring-pressed ball 13. The revolutions of the sleeve are transmitted to the pointer 26 through gearing 35, a worm shaft, worm-wheel, and friction clutch. The presence of the friction clutch allows the indicating pointer to be turned back to zero irrespective of the gearing.

Patent GB-463406-A (GB)
Title: Improvements in or relating to cementitious materials
IPC: C04B22/12
Filed: 1935-08-22
Abstract: The efflorescence of cementitious materials, such as Portland cement and lime and gypsum plasters, in which calcium hydroxide is present or is formed is prevented by incorporating sodium fluoride in the cement before it has set.  Other salts which react with the calcium hydroxide to form an insoluble calcium salt may also be added. Additional salts specified are salts of comparatively low solubility such as magnesium carbonate, magnesium fluoride, aluminium fluoride and sodium oxalate, and salts of higher solubility such as ammonium carbonate, sodium carbonate, potassium fluoride, ammonium fluoride and potassium oxalate; the salts of high solubility are particularly useful when the cement contains a relatively large proportion of free lime.  The sodium fluoride, with or without the additional salts, is preferably mixed with the cement during the manufacture of the cement, but it may be dissolved in water and incorporated in the cement just before use. The fluoride is preferably used in such amounts that it will form a saturated solution with the mixing water of the cement and leave an excess of salt, viz. about 5-7 per cent of the cement. Specifications 290,309, [Class 22], 355,902; and 423,694, [Group X], are referred to.
