Title: Improvements in and relating to means for ventilating enclosures
IPC: F28D1/02
Filed: 1930-01-16
Abstract: 351,025. Ventilating apparatus. CARRIER ENGINEERING CO., Ltd. and GROOM, S. L., 24, Buckingham Gate, London. Jan. 16, 1930, No. 1569. [Class 137.] Ventilating apparatus for an enclosure comprises a heat exchanger supplied with steam, a fan drawing air over the exchanger and means sensitive to the thermal conditions in the enclosure for varying the speed of the fan and consequently the flow of air for controlling the heat transfer. With this arrangement there is no need to throttle or cut-off the steam and condensation in the heater is therefore minimized. A mixture of fresh and return air from inlets B, B1 respectively is drawn over a steam heater C in a casing A and distributed to the enclosure by means of outlet nozzles D preferably adjustable as regards direction. As shown in Fig. 1 a fan E is provided for each outlet, the fans being connected to a common shaft G by thermostatically controlled clutches F by which one or more fans may be shut off at different temperatures. Alternatively the fans may be controlled by varying the speed of the driving motor H. For this purpose the control arm of a variable resistance in series with the field winding of the motor is actuated by a thermostatically controlled compressed air motor. As shown in Fig. 2a the casing is provided with additional inlets B2, B3 for fresh and returned air in such a position as to byepass the heater C. The air inlets may be provided with manually or automatically operated baffles to control the amounts of fresh and returned air. In a modification the casing is adapted to be disposed over existing radiator systems.

Patent GB-577146-A (GB)
Title: Improved apparatus for applying adhesive tape or similar adhesive wrappings to packages
IPC: B65B7/28
Filed: 1944-01-28
Abstract: 577,146. Fixing adhesive tape. ADHESIVE TAPES, Ltd., and KININMONTH, C. P. Jan. 28, 1944, No. 1646. [Class 73] Apparatus for applying adhesive tape or wrapping to packages comprises a freely rotatable support, means for holding the package from movement with the support whilst the tape is. applied and clamping means for subsequently holding the package to the support so that they are made to rotate together to complete the wrapping. As shown, a package c is delivered on to a table a from a shoot b. Two levers d, e are moved by driven pins f to grip the package and hold it against movement with the table whilst the tape, which is fed from a reel i, is applied by the lever e to one side of the package. The clamping device m, which has its axis of rotation coincident with that of the table, is raised and lowered by a cam track n or electromagnetically. It comprises a spring - controlled, slidably - mounted plunger which drops down when immediately over the package which has just been delivered on to the table, clamping it to the table, the levers d, e then opening to allow the package to rotate with the table whilst the tape is applied. When the tape has passed right round the package, the levers d, e close again, the lever e carrying a knife o which severs the tape. A lever p on the lever e has a forwardly projecting arm which holds the tape in position for applying to the next package. A curved spring wiper s presses the cut end of the tape against the package. The plunger m is finally lifted by the cam n and the parcel thrown off the table by centrifugal force or otherwise. Tabs, in the form of paper discs, may be contained in a tube and attached to the tape as it approaches the table, the adhesive coating of the tape withdrawing the outermost disc against the action of a projecting flange or a plurality of thin claws. The tab remains on the end of the tape when the latter is cut, to facilitate subsequent removal. In an alternative construction, the packages are moved successively on to the rotatable table by a reciprocating plunger operated by a rotating cam. As each one reaches the table it is thrust against the adhesive side of the tape which is still attached to the previous package. The cutting mechanism, which is carried round by the clamping unit, consists of an arm carrying a blade mounted on a spindle which is normally held from rotation. At the appropriate instant, the cutter arm revolves, severing the tape, and the two loose ends are pressed against the sides of the packages by spring wipers. The tape may be held in tension by a coiled spring &c. In another modification, the cutting operation is effected by a second reciprocating plunger. A plurality of clamps may be employed instead of one, so that one clamp is brought into action as the clamp behind it is releasing the previous package.

Title: Preparation of filamentary materials
IPC: D01D1/04
Filed: 1952-01-22
Abstract: <PICT:0713207/IV (a)/1> <PICT:0713207/IV (a)/2> In a band-spinning apparatus, the melting-tube is of uniform cross-section at the end where the band of filament-forming material enters, but the cross-section varies to give an increased area of heat transfer towards the outlet end.  The crosssection of increased area may be such as to decrease the thickness of the filament - forming material, and may further be arranged to give an obstruction in the passage by which any unmelted material is deflected into contact with the heat transfer surface.  As shown, an apparatus comprises rollers 25, 26, for feeding a band of filament-forming material into the passage 12 of the melting tube 11, which is surrounded by a heating jacket 13. The passage 12 is of rectangular cross-section at the inlet end but, towards the outlet end, opens out into a cone 15 with a central conical obstruction 16, so as to provide an annular passage 17 of increasing surface area per unit length and so as to decrease the distance of any part of the filament forming material from a heat transfer surface.  The molten material is finally extruded from chamber 18 through the orifices 22.  The chamber 18 may contain a series of screens, or a bed of sand, to filter solid particles from the molten material.  In a modification, Fig. 6, the increase in area is accomplished by providing one wall of the rectangular passage, towards its outlet end, with a series of longitudinal ridges of uniform section, shown at 35, which protrude almost right across the passage.  The filament-forming material may be a polycarboxyamide, polysulphonamide, polysulphone, polyurethane or polytriazole.
