Title: Method and apparatus for simultaneously conditioning and conveying films of plastic material in a conditioning apparatus
IPC: B29C71/00
Filed: 1958-10-17
Abstract: <PICT:0858154/IV(a)/1> Thin plastic film is simultaneously conditioned and conveyed in a conditioning apparatus by directing at an oblique angle to the plane of the film one or more streams of heated air against at least the undersurface of the film to raise the temperature thereof and remove any internal stresses existing in the film, and utilizing said air stream or streams to propel the film through the apparatus in such manner that, during the heating step, physical contact between the film and the apparatus is avoided, whereby the conditioned film is maintained in an unstressed state. By "conditioning" is meant applying to the film a constant temperature at which the molecular structure of the film is returned to and/or maintained in a state corresponding to that of unstressed film. Preferably, two air streams are directed against the film, one stream being arranged to impinge on the undersurface of the film and the other stream on the upper surface thereof.  Suitable apparatus comprises a tunnel through which the film is conveyed and means for directing one or more heated air streams obliquely against at least the undersurface of the film. The apparatus shown includes a mechanically operated film supply roller 16 which causes the film on unwinding to form a free loop 18 extending between a source of light 19 and a photocell 20 controlling the roller speed.  The tunnel 3 is provided with two oppositely positioned sheaths 1, 2, which are each provided with at least one air-blowing fan 5, 6 and at least one heating element 9,10, and have openings through which the air streams are fed on to the surfaces of the film.  These openings may be provided with deflectors 7,8, The sidewalls of the tunnel may be made of yielding material, whereby the positions of the roof and floor of the tunnel may be adjusted relative to each other.  The tunnel may be pivotally secured to a machine for applying a subsequent treatment to the film, e.g. a press 13, 14, the pivotal movement of the tunnel relative to said machine, e.g. about hinge 15, allowing the formation of a loop of film 28 at the entrance of the machine.  Additional features of the apparatus may include yielding flaps 21, 22 at the input end of the tunnel, angularly disposed flaps 24, 25 which serve to maintain a constant air pressure along the length of the tunnel, and a turbine 29 having means operatively connected thereto for adjusting the speed of fans 5, 6.

Abstract: 1471407 Road-vehicle direction-indicators LUCAS ELECTRICAL Ltd 13 May 1974 [12 July 1973] 33330/73 Heading G4Q  Cancellation of direction-indicator lamp flashing on completion of a turn is effected by a generator producing a pulse of fixed duration which cancels an electric switch which operates the lamps. A button 110 when pressed energizes permanent magnet relay coil 103 to change-over contact 105 and to close contact 106 to connect flasher 107 to lamps 108 and to a tell-tale 109. The steering wheel incorporates a permanent magnet 117. Assuming a left-hand turn reed switches 118, 119 are conditioned whereby at the completion of the turn transistors 143, 144 are turned on for a fixed period, determined by a capacitor 139, and winding 103 is energized to return contacts 105, 106 to normal. Thus rapid steering wheel movement leaves insufficient time for certain cancellation of flashing. If the "right-hand turn" switch 110a is pressed at any time, flashing is cancelled.

Abstract: 1473732 Change speed control AUTOMOBILES M BERLIET 31 July 1974 [6 Aug 1973] 33704/74 Heading F2D The position of movable members such as sliding selector rods 101, 102 controlling forward ratios, reverse and neutral in a motor vehicle transmission, is recorded at any instant by a binary logic counting code in which each possible condition of the transmission is associated with an element of a binary coding standard, all the elements of which have the same number of bits, each bit being defined by a detector which co-operates with each of the said movable members. This reduces the number of detectors, such as electrical contacts, hydraulic, pneumatic (e.g. logic), optical or electronic devices, in comparison with the usual limit switches for positional indication. The principle for two rods 101, 102 is shown in Fig. 1. A transverse bar 109, pivoted on a fixed axis 111, overlies both rods 101, 102 each of which has two notches 105 ... 108 which, when aligned, allow the bar 109 to fall and emit a "0" signal, whilst when the notches are disaligned, as shown, the bar is raised by the surface of one of the rods and emits a "1" signal. The device may be applied to transmissions having in addition to neutral and reverse, five, six, eight, fourteen, thirty or any other number of forward ratios. In a six ratio and reverse control, Fig. 3, three bits, comprising microswitches a, b, c, are controlled by three transverse bars 109, 209, 309 overlying four three-position selector rods I ... IV, notched as shown. The binary code is as follows. In neutral all the bars 109 &c. are down, emitting signals "000" at the microswitches abc. In first ratio, with the selector rod I moved right, the rod 309 alone is raised, signalling "001"; in second (II left), 209 alone is raised giving "010"; in third (II right) two bars 209, 309 are raised giving "011"; similarly fourth gives "100"; fifth "101"; sixth "110" and reverse "111". In Fig. 4, not shown, four transverse bars 109 ... (409), overly eight selector rods controlling fourteen forward ratios and one reverse. The system separates the detectors, such as microswitches from the mechanical components, and may be applied to existing transmissions by replacing the casing and appropriately notching the selector rods.

Abstract: 781,759. Fluid-pressure servomotor-control systems. SEMPELL, E., [trading as RHEINISCHE ARMATUREN-UND MASCHINENFABRIK A. SEMPELL KOMM-GES.]. Dec. 4, 1953 [Dec. 5, 1952; June 1, 1953], No. 33799/53. Class 135. In a safety valve in which the closure member closes in the direction of flow of the controlled fluid and is actuated by an actuating fluid under the control of an auxiliary valve, the closure member is adapted to reduce progressively the escape of actuating fluid as it approaches its open position, and the valve outlet is provided with means for progressively reducing the flow of the controlled fluid as the closure member approaches its closed position. In Fig. 1, the closure member comprises a piston 9 co-operating with a valve seat 6 and slidable in a cylinder 8 co-axially mounted by ribs 8<1> in the inlet part 1 of the valve housing. The cylinder 8 is connected through ports 131, 13<11>, 13<111> with a duct 12 connected to the widened part of a venturi nozzle associated with an auxiliary valve. When the pressure in the inlet 5 reaches a predetermined value, the auxiliary valve opens and the pressure in the duct 12 is reduced. The ports 13<1>, 13<11>, 13<111> are progressively obscured by a piston 11 secured to the piston 9 so that the exit from the cylinder 8 is progressively obstructed. In the closing movement of the valve, the pressure in the duct 12 is increased upon closure of the auxiliary valve and a ported cylinder 14 rigid with the piston 9 gradually enters a recess 17 in a body 16 co-axially mounted in the outlet member 2 so that pressure builds up in the cylinder 14 to damp the closing movement of the closure member. In Fig. 2, the valve comprises a differential piston 25 with a through passage 29 and a part co-operating with a valve seat 30 about the outlet 31. The piston 25 slides in a stepped cylinder 24 mounted in the inlet duct 21 and forming with the piston 25 an annular space 27 successively exposed to actuating fluid at different pressures through tubes 321, 32<11>, 32<111>, these being cut off in succession as the valve opens. Each tube is laterally connected to the wide part of a divergent nozzle associated with an auxiliary valve. The closing movement is damped by means similar to that shown in Fig. 1.
