A method of producing thermoplastic film having a surface roughness of from 0À03 to 5À0 microns, comprises stretching an at least uniaxially orientated, thermoplastic film in a transverse direction at an elevated temperature, one or both surfaces of the film being maintained at a temperature below the orientation temperature of the film and the interior of the film being maintained at a temperature at or above the orientation temperature of the film. Preferably, the surface roughness is from 0À1 to 1 micron, and forced cooling may be used to control the temperature of the surface or surfaces of the film. The surface or surfaces of the film may be maintained at a temperature from 10‹ to 45‹ C. below the temperature of the interior thereof. Specified film materials include polypropylene and polyethylene terephthalate. Such films may be made by annular extrusion and thereafter stretched by internal pressure. In apparatus as shown tenter means comprises rails 8, chains 9 with engaging members, sprockets 10 and 11, reflecting mirrors 12 consisting of an arcuate surface (see Fig. 14, not reproduced) of an infra-red heater; a reflecting plate 13, air supply ducts 14, holes 15 for injecting heated air from ducts 14, heaters 16, fans 17, inlets 18 and an infra-red heater 19. The reflecting mirrors 12 and heater 19 are arranged with the reflecting plate 13 on the opposite side with respect to film f as shown in Fig. 14. In operation, the electric power to the infra-red heater is adjusted to impart the desired orientation characteristics to the film, and the hot air in the whole of the orientation chamber is circulated to maintain the orientation temperature uniform, i.e. the temperature in the interior part of the film.

Abstract: 1,053,674. Control systems for hoists. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 18, 1963 [Nov. 16, 1962], No. 43456/62. Heading B8L. The loading-door of a hoist conveyance 1 is required to be closed or opened respectively when the conveyance is below or above ground level, a supervisory circuit providing an alarm if these conditions are not fulfilled. Cams 6. 7 are coupled to winding-drum 5 so that contacts 9 are opened and contacts 10 are closed when the conveyance is hoisted above ground level. Relays 17, 18 are energized from receiver 19 associated with transmitter 20 transmitting A.C. signals over wire rope 4, the transmitter being operative only when the door is opened. Normally, when the conveyance is below ground, relay contacts 15, 16 are opened and closed respectively whilst contacts 9, 10 are closed and opened, whereby neither of the alarm bells 11, 12 is operated. When the conveyance is hoisted above ground level, and the door is opened, transmitter 20 is operated to close contact 15 and open contact 16. Since the contacts 9 and 10 are now open and closed respectively, neither of the alarm bells are energized. If the supervisory arrangement fails, contacts 16 remain closed and the alarm bell 12 is sounded when the contacts 10 are closed. If the door is opened while the conveyance is below ground level, contacts 9 and 15 will be closed simultaneously to energize alarm bell 11. If the conveyance is above ground level but the door remains closed, contacts 10 and 16 will complete a circuit for the alarm bell 12.

Abstract: 1,229,410. Controlling webs. UNIROYAL Ltd. 23 Aug., 1968 [24 May, 1967], No. 24132/67. Heading B8R. The tension of a web or wire 2 drawn from a reel mounted on the shaft of a rotary pump/ motor 1 is sensed by a pulley 41 mounted on the end of a pivoted arm 39 and adapted to move the needle of a pilot vent valve 5 controlling the flow of fluid in a line 4, 6 by-passing a relief valve 3 to which fluid is pumped from a tank 35 by the pump/motor 1. The latter is driven by the reel of wire and the back pressure of the pump retards the reel. The needle valve 5 is urged to the closed position against the tension of the wire by a piston 48 in a cylinder 49 connected to a source of compressed air. A dashpot 45 prevents the needle valve from hunting. When the tension in the wire increases the needle valve 5 opens and the fluid pressure in the system consequently drops and the retarding effect of the pump/motor 1 on the reel decreases. The pump/motor 1 also serves as a motor to re-wind the wire on to the reel, being then supplied with fluid under pressure by a pump 16 driven by an electric motor 17 and connected through a non-return valve 14 to the pump/motor 1 on the same side as the relief valve 3. In order to prevent the escape of fluid through the relief valve 3 when the pump/motor 1 is being used as a motor a stop valve 8 actuated by a solenoid 9 is connected downstream of the relief valve 3. During take-off of the wire from the reel the pump 16 is kept running but the non-return valve 14 is closed and the fluid passes through a relief valve 19 to the pump/motor 1, any excess passing through a non-return valve 33 to the tank. The relief valve 19 may be by-passed by either a valve 28 to provide a very low pressure or by a valve 31 to provide a low pressure, one or other or neither valve being made operative by solenoids 24, 25. The very low pressure is used to maintain the tension in the web when the reel is stationary, the normal pressure (both valves 28, 31 closed) to overcome the inertia of the pump/motor 1 and start the reel rotating and the low pressure (valve 31 open) to keep the reel rotating. Instead of a reel the wire may pass spirally around a cylinder on the shaft of the pump/ motor 1.

[Also in Division G4] In a system in which a pneumatic reading head senses simultaneously the data in a block of data on a record carrier, the channels conveying the fluid signals from the head to a processor are closed during transport of the carrier to position a succeeding block of data under the reading head. Each channel comprises a pair of ducts 12, Fig. 1, a plurality of such ducts being mounted on plate 1. Fluid from the reading head passes into the respective ducts 13, Fig. 4, of the pairs 12 and flows out of ducts 16 to the processor, e.g. a machine tool system. During record carrier transport a fluid signal is applied to duct 23, Fig. 1, so that diaphragm 22 moves downwardly to depress push rods 19, one lying above each inlet duct 13. The push rods seal the bores of ducts 13. Two assemblies may be arranged back to back, Fig. 3 (not shown). Each inlet duct is connected to sleeve 11 inserted in recess 14 of plate 1 (Fig. 4) having a bore 10 opening into coned recess 14 merging into blind bore 15 to which the corresponding outlet duct is connected, and a pot-shaped seal having a rim clamped between plates 1, 2 is positioned over the head of sleeve 11 so that its bore is normally open without leakage, to connect the inlet and outlet. The corresponding push rod sliding in a bore 18 of plate 2 is headed to engage the underside of the diaphragm 22 so that in normal operation with zero pressure at duct 23 signals are transmitted from respective input to output ducts during reading.

Abstract: 1,266,946. Flat films. ASAHI KASEI KOGYO K.K. 1 Oct., 1969 [5 Oct., 1968], No. 48194/69. Heading B5B. Flat films are produced by melt extruding a thermoplastic resin through an annular orifice, slitting the tubular film during cooling, and solidifying the same by passing it through a cooling stabilizer, and flattening the slit material along guide plates. In apparatus as shown, a melt, suitably of polyamide or polypropylene is extruded from die 1, through an annular orifice 11, and the tubular film produced passes down into the cooling stabilizer 2, which consists of a main cylindrical body 21, and a flow adjusting ring 22, which is fixed vertically in the cooling bath 3. The slitters 23, which have knives 231 attached, are attached to the main body 21, and slit the film longitudinally; the film then passes over guide plates 4, which are of semicircular form at the top but become progressively flat towards the bottom (Fig. 3, not shown), in order to flatten the film from its semicircular shape. The films are fed to a takeup device (not shown) by means of two parallel guide bars 5 and a direction changing bar (6) (Fig. 4, not shown).  The cooling stabilizer 2 is situated in the cooling bath 3 such that the upper end of the main body 21 is below the liquid surface in the bath but higher than that inside the tube. Cooling liquid flows down a space between the cylinder 21 and the tube A from the flow adjusting ring 21. The film is stabilized due to the velocity of the cooling liquid inside the tube being lower than that outside, and this causes any pressure applied vertically to be greater inside than outside, so causing the tube to expand from the inside. The length of the stabilizer, d, is between 50-600 mm. in order to achieve the most favourable operating conditions.  The flat film produced is homogeneous and has no structural difference between the surface side and the back side.
