IPC: B05B7/14
Filed: 1969-09-18
Abstract: 1,247,083. A spraying nozzle. ENGINS MATRA. 18 Sept., 1969 [18 Sept., 1968], No. 46169/69. Heading B2F. A nozzle for simultaneously projecting a finely divided solid, e.g. glass fibre, and a liquid, e.g. a resin, which impregnates it comprises an inner jet for the projection of the solid and means for projecting the liquid therearound. In the embodiment shown, a gaseous suspension of the finely divided solid enters the device from the right and is constricted by the frusto conical section 33; after passing through the cylinder 34 it is further constricted by an annular jet of compressed air supplied from the annular chamber 38 via the line 18. This serves to space the jet of solid suspension from the inner surface of the forward section of the device. Finally the suspension issues from the forward end of the device as a circular jet. The liquid to be projected issues from jets 22 arranged symmetrically in annular face plate 21 being supplied either alone, or with compressed air by means of an annular groove 15 via the line 16. The device may be attached to a spray gun as shown in Fig. 4, the gun carrying apparatus 46 for the production and projection of chopped glass fibre.

As shown output shaft 10 is integral with a crank member 9 and the locking means is a member 16 slidable thereon. Member 16 is spring urged to engage in recesses 151 in an annular member 15 which is secured between fixed housing parts 1 and 2. Thus the member 9 and arms 91, 92 are held stationary until, after sufficient rotation of shaft 7, arm 81 or arm 82, according to whether the rotation is clockwise or anti-clockwise, impinges on a release lever 19 or 20 to withdraw member 16. This allows compression springs 13, 14 to reassert by rotating the second lever 11 or 12 (according to direction) and arms 91, 92 with a snap action. This turns output shaft 10 which is coupled to the switch contacts (not described) until member 16 enters the next notch in member 15.

Title: Automatic film processing apparatus
IPC: G03D3/08
Filed: 1964-11-25
Abstract: 1,061,240. Photographic processing apparatus. T.H. HILLS. Nov. 24, 1965 [Nov. 25, 1964; July 30, 1965], Nos. 47885/64 and 32630/65. Heading G2A. In apparatus for processing cut photographic film the transport means comprises a rotatable paddle wheel 6, for each of a plurality of stages in the process, arranged so as to receive a portion F of cut film between adjacent paddles and to support and convey the film through a container 1, and a pair of rollers 7, 8 associated with each paddle wheel arranged to receive each portion of film from its paddle wheel at the completion of its movement through the container and to transfer the film to the paddle wheel of the next following container. Each paddle wheel is provided with means for moving each portion of film radially outwards at the end of its movement through the container to cause the outer edge of the film to enter the nip of the rollers. In the embodiment shown, the paddle wheels are of wire mesh and are welded to stainless steel rings 9-12 and to tubular members 14 rotatable on a fixed axle 15. The axle also carries a cam 19 for moving the film radially outwards at the end of its travel through the processing liquid, the paddle wheels being cut away where necessary to avoid contacting the cam 19. The film is prevented from falling out of the wheel by a curved guide 18. A plurality of stages, one of which may be drying, in processing the film are arranged one after the other in a light tight box 20 having a removable lid 21. The paddle wheels for each stage may be of different diameters and have different numbers of paddles if the periods to be occupied in passing through different stages are different. In another embodiment Figs. 3-5 (not shown) the paddle wheel is in skeleton form, i. e. the paddles comprises flanges 24 upon spokes 25 which thus support the cut film along its opposite edges. To move the film into the nip between the rollers 41 a hinged flap 52 is provided hung from a fixed rod 53. The flap is urged into contact with a film F by a spring lever 55 attached to a rotatable block 56. Mechanism 61-65 is engaged by each flange 24 in turn as the paddle wheel rotates, thus pivoting the block 56 and moving the flap 52. To add developer and fixer to the appropriate tanks in a volume proportional to the number of films processed, films leaving the drying compartment interrupt a light beam to a photo-cell which thus operates a solenoid to release the chemical solutions. The apparatus may be made of a synthetic resin or of stainless steel.

Abstract: 1,032,300. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1964 [Dec. 5, 1963], No. 48082/63. Heading H2J. The speed of lift motor 1, which is supplied from generator 2, is controlled in accordance with a programme, the speed being monitored at one or more points during the programme by an emergency stop relay 14. In normal operation of the system, the relay is operated by current derived from a D.C. source through resistor 18, this current being reduced when one of the limit approach switches 20, 21 is opened to introduce the resistor 19. If the voltage across rectifier 11 is excessive, then an opposing current, which represents the speed of the lift motor, is sufficient to reduce the relay-current to the release-value so that the motor is braked to a standstill. Zener diode 16 prevents false operation of the relay if rectifier 15 is shortcircuited, and protects the relay-coil if excessive current flows from point C. The rectifier 15 is guarded against voltage peaks by capacitor 17. The resistor 18 may be adjusted so that excessive speed of the lift is prevented throughout the whole of its travel. The excitation of generator 2 is controlled by a power amplifier associated with a pre-amplifier whose input is derived from a ramp function generator opposed by feedback from a tachometer generator. The input to the ramp function generator is controlled by potentiometers providing full, intermediate, pre-levelling, and levelling speeds respectively. The potentiometers are connected to switches which are selectively operated in accordance with the position of the lift relative to its destination. In another speed monitoring arrangement, the relay has one coil energized in accordance with the desired speed to maintain the relay normally operated, and an opposing coil receiving the current corresponding to actual speed, to release the relay when overspeed occurs.
