Title: Improvements in or relating to armchair frames
IPC: A47C4/02
Filed: 1952-06-04
Abstract: 697,386. Seats; furniture frames. JAMES, B. June 4, 1952, No. 14063/52. Addition to 697,374. Class 52(ii) The arm chair frame claimed in the parent Specification is modified so as to enable additional seat and back units to be connected to form either a two-seated or a three-seated settee. As shown the seat unit, Fig. 1, is modified so that the inner one of the tongued side rails is shorter than the other as is the case with the 'outer additional seat'unit, Fig. 3, while the intermediate seat unit, Fig. 2, has two shortened side rails X, Y. All the seat units are provided with the appropriate T-shaped tongued or grooved side rails. The back unit, Fig. 8, is modified by the omission of the wing W at one side and the provision of the T-shaped tongue S along the whole of that side. The outer additional back unit, Fig. 10, is similarly constructed except for the provision of the T-shaped grooved rail Z in place of the tongued rail. The intermediate back unit, Fig. 9, has both its side rails X, Y devoid of wings W. The arm and top arm units remain of the same construction as described in the parent Specification.

Title: Improved method of and apparatus for fractional distillation
IPC: C10C1/04
Filed: 1920-05-21
Abstract: 170,324. Thermal Industrial & Chemical (T.I.C.) Research Co., Ltd., and Duckham, Sir A. M. May 21, 1920. Column stills and rectifiers; hydrocarbons, distilling.-In the fractional distillation of liquids, such as tar, the liquid to be distilled is passed through one or m o r e sections of the condensing- column, and the temperature of the section is regulated by regulating the flow of the liquid through the section, for example, by a thermostat. In an apparatus for obtaining three fractions, the vapours pass from a still i through a column of two sections each consisting of a packed chamber b, and a chamber f through which pass tubes e. The liquid to be distilled is passed from a tank k through the upper chamber f down pipe h, through the lower chamber f and thence by a pipe g into the still i, together with the vapours evolved from the liquid. In distilling tar, the upper chamber is maintained at about 85‹ C., and the lower chamber at about 180‹ C. by thermostatic control, bypass pipes being provided. The upper tube-plate in the chamber f may be omitted so that the vapours evolved from the liquid may mix with the vapours rising in the column.

Grates.-Revoluble grates of the kind described in the Parent Specification are divided into two fuel zones or compartments by .gratings, the space between which is divided by a partition into passages for supplying air to the fuel in one compartment and for .the escape of gases distilled from the fuel in the other. In the form shown in Fig. 2 parallel gratings j, j' divide the revoluble cylindrical grate a into two fuel .compartments m, m<1>. The space ibetween the gratings is divided by a partition k into paasages l, l<1>, the former serving to supply air through the grating j to the fuel in the compartment m, and the latter for passage of gases distilled from fresh fuel in the lower compartment m<1>. The gases pass out at the upper end of the passage l<1> and are consumed in the passage g, air being supplied through a passage or passages n. One or more openings o are preferably formed in the gratings to form a communication between the fuel compartments. In the grate shown in Fig. 5, the partition k is pivoted so as to retain its position relative to the two fuel compartmentswhen the grate is inverted.

Abstract: 501,492. Artificial filaments. DONAGEMMA, G., DONAGEMMA, P., and SNIA-VISCOSA SOC. NATIONALE INDUSTRIA APPLICAZIONI VISCOSA. May 13, 1938, No. 14337. Convention date, July 23, 1937. [Class 2 (ii)] Waste cellulosic material from the tanks and drains of artificial silk or staple fibre spinning or bleaching baths is utilized as starting material for the production of artificial silk. The waste material is treated with caustic soda solution to extract waste soluble matter, the alkaline residue is converted into viscose and the viscose is formed into filaments. In an example, waste threads from acid spinning baths are washed and dried. They are then soaked in caustic soda solution and the excess of solution is subsequently removed together with the dissolved degraded celluloses. The alkaline residue is crushed, ripened, treated with carbon disulphide, and mixed with dilute caustic soda. The viscose thus obtained is filtered, subjected to vacuum treatment, and then extruded into a coagulation bath.

The margin is flexible, as usual, and the stiffer part of the central area may comprise an isosceles triangle having its base substantially parallel to the back margin of the puff, or the base may be hollowed and the sides substantially hollowed, as shown, to enclose a. roughly #- shaped area. A toe-puff blank of rubber-impregnated felt, as described in Specification 277,719,. or of thin cork linoleum, or of cloth, felt, or paper, may have a reinforcement of thermoplastic material at the above area only. Alternatively, a lightly impregnated blank may be dressed at the above area with a coating of lesser thermoplasticity than that of the remainder, e.g. Montan wax or shellac, applied through a stencil. A blank of cotton cloth, lightly impregnated with 90 per cent colophony and 10 per cent carnauba wax may have applied to the above area a sheet of muslin charged with 50 per cent celluloid and 50 per cent colophony. In a modification, a sheet of celluloid or thin stiff fabric, such as twill, of the shape of the above area may be cemented by heat and pressure to the blank. Specification 290,519, also, is referred to.

Hydrostatic torque-measuring apparatus as claimed in claim 3 of the parent Specification, with a hub for connecting a vane disc 31 to a shaft, has the hub keyed to the disc 31 by forming it as a toothed bush 33 with external teeth 34 engaging internal teeth 34a of the disc 31 with their tooth gaps serving as axially extending oil passages for the supply and withdrawal of oil current through the vane disc 31 and displacement chambers (5) between the vanes of the disc 31 and those of the vane housing 32. The bush 33 is directly surrounded by a bearing bush 36 for a stationary transmitter 38, inner races 35 for ball bearings 3 and the disc 31 which are axially clamped against its end collar by a threaded disc 37. An O-ring 42 against support ring 43 in an annular groove 31h forms a seal lying between radial bores 31b, 31c in the disc 31 and ensures that oil from the transmitter 38 passes through the displacement chambers before returning through the axial bores 31i to the discharge opening 38a.

[Also in Group XXVI] A jet propulsion nozzle ending in a circular outlet comprises an outwardly convex curved annular surface having a minimum diameter greater than that of the outlet and extending around the outlet in radially spaced relation to form an annular gap facing upstream and downstream, and flaps pivoted on the nozzle and movable through the gap between a retracted position outside the nozzle and jet stream and an operative position lying across part of the jet stream. In Fig. 4, the annular surface is in two parts 2a, 2b, the former fixed and the latter attached to a grid of blades 3 and movable between inoperative (upper part of Fig. 4) and operative (lower part of Fig. 4) positions. The movable members are each in two parts 6a and 6<SP>1</SP>a, and 6b and 6<SP>1</SP>b. The upper part of Fig. 4 shows the nozzle in normal operation, members 6a, 6<SP>1</SP>a being retracted into the gap 5. For deflection, members 6<SP>1</SP>a and 6<SP>1</SP>b remain retracted and members 6a, 6b are moved to a central abutting position as shown for member 6b, and the jet is deflected into the grid of blades. To vary the nozzle area, the members are operated in the manner of eyelids, either equally or to different extents to give a deflection of the jet. Ambient air is drawn in through the gap 5 by the jet, and serves to detach the jet from the guide surface 2a, 2b, when deflection is not required. Alternatively, Fig. 5 (not shown), the guide surface may be in one part, fixed with the grid of blades to the nozzle, and the exterior fairing of the nozzle may be movable axially to cover or expose the grid of blades.
