Abstract: 1,045,328. Slot die for melt-extruding films and other sheet materials. F. SOMMERFELD. Jan. 22, 1964 [Jan. 22, 1963], No. 2774/64. Headings B5A and B5B. A slot die for making films and other types of sheet materials by the melt extrusion of synthetic organic thermoplastic polymeric materials comprises plates 1, 2 and 3 (Fig. 1, not shown, which is a side view in central section of the slot die) which are firmly held together by means of the screws 10b (Figs. 9, 10 and 12, not shown), and are aligned in relation to one another by means not shown. The plate 1 is machined on all sides and has a recess 13 (Figs. 9 to 11) into which an inlet channel leads at the top and in the middle. The channel is bounded at the other side of the plate 1 by a recess 28 (Fig. 10), which serves to receive the member 4 (Figs. 1, 3 and 4, not shown). An arcuate slot 11 is machined in the plate 2 (Figs. 12 and 13, not shown), which is likewise machined on all sides. A recess 14, which is bounded at the top by the aperture 15 is machined in the plate 3 (Figs. 14 and 15, not shown), which is likewise machined on all sides. The lower surface of the aperture 15 merges into the lower lip 5 of the extrusion slot and the upper surface of the aperture 15 merges into a projection 8 having a threaded bore 19a. A chamber 16 machined out above the aperture 15 receives the guide member 6 of the upper lip 7 of the extrusion slot. When the plates 1, 2 and 3 are bolted together, as shown in Figs. 1 and 4, the recesses 13 and 14 together with the plate 2 form compartments 13 and 14 which are in communication with one another through the slot 11 in the plate 2. The member 4, bolted to the plate 1, is for the connection of the inlet 12 of the slot die to a source of hot plastic film-forming material under pressure, for example, a screw extruder. The upper lip 7 with its guide member 6 (Fig. 1) constitutes the upper boundary of the compartment 14 and also, together with the lower lip 5, defines the extrusion slot and the passageway leading thereto. The coarse adjustment of the width of the extrusion slot is effected by actuation of the screws 20. The fine adjustment is effected by actuation of the screws 19 by means of which the lip 7, which is resilient in relation to the guide member 6 can be flexed to the required degree. The extrusion slot of the die is sealed at the ends by two bars 9 (Fig. 4), which are held tightly against the plate 2 by two screws 18 located in the bores 18b in the plates 1 and 2 (Figs. 9 and 12). The bars 9 are urged against the lower face of the aperture 15, the lower lip 5 and the upper lip 7 by the grub screws 17 located in the bores 17a and 17b (Figs. 4 and 14). The arcuate gap or slot passageway 11 in the plate 2 is so disposed with respect to the inlet duct 12 that the condition a+b=c is always complied with as shown in Fig. 5. In the centre of the 13, a=b=c/2. From the middle of the mouth of the duct 12 leading into the compartment 13, the plastic material is distributed radially as shown, for example, by the arrows b 1 , b 2 , b 3 .

Title: Improvements in and relating to rotary piston pumps
IPC: F04C15/00
Filed: 1965-01-22
Abstract: 1,099,903. Rotary pumps. LAPP INSULATOR CO. Inc. Jan. 22, 1965 [Jan. 22, 1964], No. 3037/65. Heading F1F. A rotary piston pump for pumping, e.g. corrosive or abrasive liquids, comprises a housing consisting of a ring-shaped member 25, Fig. 3, having a bore 34 forming the pumping chamber and inlet and outlet connections 36, 37, Fig. 1, a back cover-plate 27, a wear plate 26, a front cover-plate 24 having a bore 31, a ring member 64 with a bore 66 and a flanged block 11 with bearing support flanges 14, 15. The axes of the bores 66, 31, 34 are coaxial with each other and with the axis of a drive-shaft 18 to which is secured an eccentric 44 bearingly mounted for rotation on rotation of the shaft 18 in a cup-shaped inner piston member 46 which is in turn concentrically mounted within an outer piston member 50 eccentrically disposed within and contacting the bore 34. The member 50 is formed with a radial axially-extending slot 56 within which is secured a vane 56 which reciprocates in an aligned slot 38 disposed in the ring-shaped member 25 between the inlet and outlet connections. Flexible diaphragms 80, 81, preferably of P. T. F. E. with a backing of fabric-reinforced neoprene are clamped around their outer edges between the housing parts and secured at their inner edges by a ring of bolts 61' to the inner piston member 46 to restrain that member from rotation and prevent escape of liquid from the pump chamber. As the shaft 18 and eccentric 44 rotate, the piston members 46, 50 are caused to revolve, without rotating, about the axis of the shaft 18 to pump liquid from the inlet 36 to the outlet 37. The working parts of the pump are made of material having a low frictional coefficient, e.g., P. T. F. E., which material also has self lubricating properties, is chemically inert and light in weight. Alternatively the inner piston member 46 may be made of stainless steel for strength, resistance to corrosion and good operating characteristics. The ring member 64 is formed with a radial bore 74 for communication with a water supply through a connection 75 and a further radial bore through which the electrodes 78 of a spark-plug 76 protrude. In the event of leakage from the pump through the first diaphragm, a conductivity meter in circuit with the spark plug will give an indication of this state of affairs. Alternatively instead of the bore 74 and spark plug 76 leakage liquid may be drained to a leak detecting device or returned to the pump inlet. In another embodiment the leakage detecting device is dispensed with altogether in which case the ring member 64 and diaphragm 81 are omitted and the block 11 is fitted adjacent to the front cover-plate 24.

Title: Improvements in door operating apparatus
IPC: E05F15/02
Filed: 1936-01-31
Abstract: 463,584. Door-operating appliances. NATIONAL PNEUMATIC CO. Jan. 31, 1936, No. 3042. Convention date, March 14, 1935. [Class 65 (i)] In a door-operating system, particularly for a vehicle, including a liquid-pressure engine fed from a reservoir containing the liquid under pressure, the control valve is placed immediately adjacent to the engine and arranged to be operated by pressure liquid through small-bore pipes under the control of another valve which is operated directly or indirectly by hand; the liquid supply to the engine thus has not to pass through a valve at some distance therefrom, and consequently the body of liquid in motion is smaller, giving increased speed of operation, and leakage at the manually-controlled valve is minimized. In the arrangement shown, a differential engine 3 is used, the pressure reservoir 7 being connected continuously to the space between the pistons while the end of the larger cylinder is connected through a valve 9 either to the pressure reservoir 7 or an exhaust reservoir 13 whence liquid is returned to the reservoir 7 by a pump 16 ; the valve 9 is operated by pressure liquid in a small pipe 19, which is connected by a manual control valve 17 alternatively to the supply and exhaust sides of the engine. All the apparatus except the valve 17 and the small control pipes associated therewith is placed below the floor of the vehicle, so that little liquid can leak into the interior of the vehicle. In a modification, the valve 17 is replaced by an electromagnetic valve situated close to the valve 9 and controlled by a switch, and in this case no pipe enters the vehicle at all.

[Also in Division F2] A tray 4, Fig. 2, in a gas/liquid contact column has apertures such as 3 provided with valves having a valve plate 2 which may be perforated as at 6, a depending and slotted skirt 1 to guide the valve in vertical movement and a travel limiting element 7 with bent-over portions 7c which will abut against the tray to limit upward movement of the valve but which are resilient and shaped to allow the valve to be inserted in an aperture from above the tray. In a modification the skirt is formed of a series of tongues and the ends of some of the tongues are bent over to form travellimiting elements. In further modifications a downwardly extending limb of a travel-limiting element terminates in a trapezoidal-shaped plate which projects through a slot in the guiding member. As shown in Fig. 6, the travellimiting element consists of a bowed resilient metal strip 18 engaged in slots in the guiding member 20 and projecting therefrom at 18b. In Fig. 8, guiding members and travel-limiting elements are formed by resilient strips 24a and 25a secured to a valve plate 21 and formed with depending limbs 24b and 25b and bent-over portions 26 and 27. Similar guiding members and travel-limiting elements may extend from a three-limbed member straddling the upper surface of the valve plate while in another embodiment downwardly extending limbs terminating in outwardly projecting portions are struck out of the material of the valve plate and when in position over an aperture the downwardly extending limbs of the valve pass through slots in the tray extending from the edge of the aperture. In this embodiment the edges of the valve plate may be serrated. In valve shown in Fig. 14 the valve-plate 45 is dished and has a serrated-edge while the guiding members and travel-limiting elements are constituted by three (two of which are shown) members 42b extending from a portion secured to the undersurface of the valve plate. In a further embodiment, Fig. 17, the guiding members 51a and limbs 51b extend from plates secured to the valve plate 48, the limbs 51b preventing the valve plate in its lowest position from completely closing the aperture 49.

Abstract: 917,051. Junction-boxes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 27, 1961 [Jan. 28, 1960], No. 3141/60. Class 38 (1). A terminal box comprising a metal casing 1 having rear and bottom cable openings 5, 4, a front access opening 3 and a flange 6 for attaching it to high-power apparatus M, has a box-like insulating lining 2 within which are joined cables 16, 17, passed through openings 5, 4, and glands 15, 19, in the lining wall. The lining has a front opening corresponding to access opening 3, both openings being closed, as shown, by a cover 8 lined with insulation 2<SP>1</SP> or alternatively a separate insulating lid may be fitted to the lining. The rear wall of lining 2 slopes forward to provide an expansion space B which helps to reduce the external effect of an explosion due to any electric fault; also a frangible panel may be secured over the opening 5 (Fig. 3, not shown) so as to explode towards the apparatus M. For multi-phase use the box may be divided into several compartments, one for each phase, by steel partitions welded to the inside of the casing (Fig. 2, not shown), each compartment having an insulating lining. The cable connections 18 may be enclosed by insulating tape 20 or the whole internal space may be filled with silicone elastomer putty. A multicore supply cable may be brought into a sealing-box (Figs. 3, 4, not shown) attached to the box below opening 4, the cores being connected to cables 16 by short interconnectors. The sealing box is partly filled with sealing compound and may be provided with humidity indicators and dessicators, e.g. of the silica gel type, if desired. In this construction the phase separating partitions extend through the casing 1 into the sealing compound, thus improving the inter-phase insulation between compartments of the multi-phase box.
