Title: Apparatus for Facilitating the Obtaining of Crystals from Solutions.
Inventor: HUTCHINS THOMAS WILLIAM STAINE
IPC: B01D9/00
Filed: 1918-02-06
Abstract: 122,507. Hutchins, T. W. S. Feb. 6, 1918. Crystallizing.-Liquor from which crystals are to be deposited, such as carbonate of soda liquor, is carried in the buckets of a bucket conveyer through cooling baths, where crystallization takes place, and then through a warming bath where the crystals are loosened from the buckets, so as to fall out freely when the buckets are tipped. The cooling baths b, c, which may contain brine coo'ed down to 0‹ C., and the warming bath d, may be arranged as shown The buckets on leaving the bath d are tilted in the ordinary way and discharge their contents on to a grid f, which separate the crystals from the liquor and delivers them to an elevator h. The liquid may be supplied to the buckets from two measuring tanks k, j, which are alternately filled and emptied through a four-way cock l, which is operated by a star-wheel m driven by the conveyer chain.

IPC: F24B1/192
Filed: 1926-01-28
Abstract: 268,083. Theobalds, R. O. P. Jan. 28, 1926. Blowers.-In a folding blower for domestic fireplaces, of the kind built up of hinged sections arranged either in one piece or in two halves a, b as shown, the first sections a<1>, b<1> are arranged to form the backs of casings to house the blower when collapsed, each casing being completed by a side wall f to which is hinged a front cover g having an aperture h to fit over the operating- handle e of the blower. The blower, or each half thereof, may either be secured to the side of the fireplace or, as shown, be mounted on feet i adapted to stand on the hearth, means for adjusting the height of the blower on the feet being provided if desired.

Patent GB-1509492-A (GB)
Title: Protective structures for high speed rotors
IPC: F01D21/04
Filed: 1976-01-22
Abstract: 1509492 Machinery guards MOTORENUND TURBINEN UNION-MUNCHEN GmbH 22 Jan 1976 [23 Jan 1975] 02538/76 Heading F2J [Also in Division F1] A protective housing structure for the high speed rotor 1 of a compressor, gas turbine or centrifuge, includes a tubular wall composed of two concentric cylindrical layers the radially innermost layer 3 of which is formed of a ceramic material such as sintered aluminium oxide which, in the event of the rotor 1 breaking up during operation, is capable of being shattered when hit by radially outwardly flung disintegrating parts of the rotor 1 so that the kinetic energy of these rotor parts is substantially dissipated within this layer 3, the radially outer layer 2 being formed as a sheet metal tube of, for example, steel, titanium or aluminium, which is shrink-fitted on the ceramic inner tube 3, and has a mechanical strength sufficient to withstand the impact of the disintegrating rotor parts upon the ceramic inner layer 3. As an alternative to shrink fitting the outer layer 2 on to the inner layer 3, the inner layer 3 may be contracted by being reduced to a low temperature and then fitted into the outer layer 2 such that the inner layer 3 then responds to fit tightly within the outer layer 2. It is stated that the high energy consumption occurring when the impact energy is converted largely into atomizing energy to destroy the cohesion of the dense and fine-grained structure of the ceramic inner layer largely neutralizes the kinetic energy of the disintegrating rotor ports such that the surrounding sheet metal tube only has to absorb a small remaining part of the released kinetic energy.

The liquid, before passing through passages in the compresser cylinders or being sprayed thereon is further cooled in a coil 7, Fig. 3.

Title: Improvements in Projectiles Carrying Extensible Coils of Wire or Chain.
Inventor: STRAUB OSCAR ITIN
IPC: F42B12/66
Filed: 1918-02-13
Abstract: 119,387. Straub, O. I. Feb. 13, 1918. Projectiles; projectile fuses. - Relates to projectiles containing one or more coils of wire or chain, which may carry weights at their end or be attached to the walls of the shell casing, the wire or chain being intended to be stretched out centrifugally after the shell casing has broken up by explosion or otherwise. According to the invention, each length of wire or chain is wound from the centre in reverse directions so that it can uncoil freely. Hardened wire, angular in cross-section to provide cutting edges, may be used. Tn the construction shown in Fig. 3, the wire is wound on a spool comprising a spindle 1 and disks 2, 3. The upper and lower parts 4<a> and 4<b> of the wire are coiled reversely and connected at 4<c>, the ends 4<d> being attached to bars 5, detachably connected to the disks 2, 3. The disk 2 is secured to a. base 6, which carries a driving-band 7, and a cap 8 carrying a fuse may be provided at the front end of the projectile. This cap may be removed, for using the projectile at short ranges, in which case the bars 5 may be tied to the disks 2, 3 by means such as combustible or fusible wires. Modifications are described in which several coils of wire are provided, connected to pairs of longitudinal bars, and in which chambers in the head and base contain explosive charges adapted to be ignited by a time-fuse; or instead of connecting the ends of the wires to bars, they may be loose within the casing of the shell, which in this instance resembles a shrapnel shell in general construction. In the projectile shown in Fig. 6, the wire is wound on a spool enclosed in a thin metallic case 11 which is blown away on discharge of the projectile by the pressure of the gun-gases, which enter through apertures 12 in the base. Figs. 14 and 16 show a shell having a number of coils E which are wound in the manner already described and are embedded in the bursting-charge F. The ends of the wires pass down grooves a<1> in the shell-walls and are secured to longitutlinal sections A<1> of the shell which are separated by deep grooves a forming lines of cleavage. The arrangement is such that when the shell is exploded, each pair of fragments A<1> remains connected by a wire E. The number of coils of wire and fragmentation grooves may be varied. In the construction shown, the bursting-charge F is ignited by a charge in a paper tube G, connected to the fuse D.

The apparatus is stated to be particulary useful in automatic gas analysis apparatus, and the gas being analysed may first be dissolved in a suitable solvent.

[Also in Division G1] In a powered screw driver or spanner, torque is transmitted from a motor driven shaft 5 to a shaft 8 connected to the socket of a tool head through an apertured, tubular spindle 3. Axial deformation of the spindle 3 is sensed pneumatically, hydraulically or electrically to provide an indication of the torque applied and may turn a lamp on or off when a minimum torque is attained, actuate a relay, to cut out the motor when a predetermined maximum value is attained or control the motor in correspondence with the torque up to the maximum allowable.

Title: Improvements in or relating to the temperature control of a liquid in a cooling circuit

Abstract: 603,230. Fluid-pressure servomotor-control systems. SULZER FRERES SOC. ANON. Feb. 6, 1945, No. 2974. Convention date, Feb. 8, 1944. [Class 135] [Also in Group XIII] In apparatus for the temperature control of a liquid flowing in the cooling circuit of an internal combustion engine &c. of the kind in which the liquid, e.g. water or oil, is recirculated. direct to the engine when below a certain temperature but, above this temperature, is circulated through a cooler, an immediate change over at the specified temperature is obtained by a servomotor comprising an expansion medium acting on a two-part valve, one part being acted on directly by the expansion medium while the other slides on the first part so as to separate therefrom and admit the pressure fluid which operates the valve cutting out the cooler circuit. Liquid is circulated by a pump 1 through the cylinder block of an engine 3 and sump 7 either through a cooler 9 and pipe 8 or through pipe 6 direct to the sump 7 the direction of flow being determined by a valve 11 operated by a piston 12 normally held against a seating 11a by a spring 13 to direct flow through line 6. Depression of the valve is effected on expansion of the bellows 21 which raises a valve comprising a spindle 17 having thereon a first fixed part 14 and a second sliding part 15 normally held in contact with the part 14 by a spring 25 so as to prevent entrance of the servo-pressure fluid through pipe 16. When however the part 14 rises and compresses the spring 25 the pressure fluid is able to separate the parts and thus gain access to the top surface of the piston 12 and depress the valve 11. When the expansion medium contracts, the part 15 falls to contact with 14 and thus cuts off the pressure medium while the pressure above the piston 12 is relieved through passage 18 and port 17a.
