Title: Recording or playback apparatus
IPC: G03B21/48
Filed: 1974-01-04
Abstract: 1453626 Cinematography: film feed K VOCKENHUBER and R HAUSER 4 Jan 1974 [5 Jan 1973 8 May 1973] 335/74 Heading G2E The speed of advance of a perforated data strip towards or away from a data transfer station by a strip feeder is controlled in response to the speed of movement of the strip by a traction claw through the station, thus maintaining the length of strip between the feeder and the station substantially constant. In the film projector of Fig. 5, a film strip 2 is intermittently advanced through a film gate by the claw 11 controlled by a cam disc 9 rotated by a continuously driven shaft 8. The drive from shaft 8 is also transmitted to a film feed sprocket (not shown), by a slipping clutch between cam disc 9 and a wheel 19 bearing a single tooth 20. Wheel 19 drives a worm 7 which co-operates with a worm-wheel (6) and shaft (4) carrying the sprocket. For advancement of the film at below normal speeds (normal speed advancement shown) an interruptor cam (12) acts on lever 14 so that for part of its rotation it allows levers 14 and 15 to pivot anti-clockwise and clockwise respectively under the influence of a spring 18. Lever 14 contacts claw 11 to hold it out of engagement with the film while lever 15 carries a nose 16 which engages the tooth 20 of wheel 19, locking the wheel against rotation and thus disconnecting the drive from the feed sprocket. A further lever 21 with nose 27 is controlled by cam 23 on the back of disc cam 9. After nose 16 has engaged tooth 20, lever 21 is pivoted clockwise by cam 23 so that nose 27 also engages tooth 20, and remains in engagement therewith after release of tooth 20 by nose 16. Finally nose 27 is moved out of engagement with the tooth by cam 23 and the wheel 19, and hence the feed sprocket, commence rotation. Thus the commencement and termination of the blocking of wheel 19 is determined by noses 16 and 27 respectively. The engagement of lever 21 with cam 23 is adjustable thus the blocking period is variable.

Title: Improvements relating to shock absorbers
Inventor: ARMSTRONG WILLIAM
IPC: F16F9/49
Filed: 1955-01-06
Abstract: 786,780. Hydraulic shock absorbers. ARMSTRONG PATENTS CO., Ltd. Jan. 4, 1956 [Jan. 6, 1955], No. 376/55. Class 108(3) The invention relates to a hydraulic shock absorber of the unidirectional flow type i.e. in which on the compression stroke, liquid is forced through a non-return valve (not shown) in the piston 1 to the piston-rod side of the piston, liquid on this side being discharged, by the action of entry of the piston rod 2 into the cylinder 13, to a reservoir 14, on rebound liquid also being discharged to the reservoir 14 by direct action of the piston, fresh liquid being induced from the reservoir 14 to the cylinder space on the other side of the piston. According to the invention, the discharge port or ports 22 by which liquid passes from the cylinder 13 to the reservoir 14, are covered at the limit of the piston travel and the end of the cylinder 13 is enclosed by the cylinder head 4. Four spaced discharge ports 22 in the cylinder 13 open into an annular channel 16 formed in the block 4. The channel 16 is connected by a passage 18, 19, with a foam tube 21 extending downwardly into the reservoir 14. A seal ring 17 is disposed beneath the channel 16. In operation, on rebound, the piston 1 cuts off the ports 22 to trap liquid in the space 23 at the end of the cylinder to form the hydraulic stop for the piston stroke. In a modification (Fig. 2, not shown), the upper end of the piston is of tapered configuration so that the ports 22 are gradually cut off. Liquid trapped in the space 23 may be allowed to escape partially by means of a bleed hole which is not at any time covered by the piston 1. The ports 22 may be spaced apart in the longitudinal direction of the cylinder 13 so as to provide a progressive action. A similar effect may be attained 'by means of an inclined groove or grooves aligned with the port or ports 22.

Abstract: 873,130. Air filters. DAVIS INDUSTRIAL EQUIPMENT CO. Ltd. Nov. 11, 1957 [Jan. 4,1957], No. 503/57. Class 8(2). An air filter comprises a sheet 4 of foamed synthetic plastic material supported zig-zag fashion by spaced parallel rods 2 secured to opposite ends of a closed-sided open-ended frame 1 of channel section 5. The frame which is of metal or plastic material is detachably secured to within a conduit (not shown), and is dipped in a bath of detergent to effect cleaning. Accumulation of electrostatic charges generated by passage of dust-laden air through the filter sheet may be diminished by earthing the frame and by metallizing the outer surfaces of the sheet. Conversely the charges may be enhanced by heating the dustladen air prior to its entry into the filter.

Title: Negative climb warning system
IPC: B64D45/04
Filed: 1976-01-07
Abstract: 1495881 Aircraft ground proximity warning systems SUNDSTRAND DATA CONTROL Inc 7 Jan 1976 [13 Jan 1975] 522/76 Heading B7W When an aircraft is taking off or is ascending after having aborted a landing the necessity for automatically giving a warning to the pilot when an inadvertant loss of altitude occurs (e.g. as at points 10 and 16, Fig. 1, of the flight path) depends on the amount of altitude los #h B  and the altitude h R  at which the loss occurs, e.g. only conditions in the shaded part of graph ,Fig. 3, should cause a warning. To meet such criteria, a warning signal is generated when a decrease of altitude is detected and the aircraft is in certain phase(s) of flight operation but the application of the warning signal is inhibited until the altitude lost #h B  comes with said shaded graph part. Thus in Fig. 2, the output hB of a barometric altimeter is differentiated to give a rate of altitude signal #h B . When #h B  is detected to be negative by means of comparator amplifier 64 a 'latent' warning signal is fed to AND gate 52. The negative value of #h B  is also detected by amplifier 40 whereupon an OR gate 42 opens switch 38 such that #h B  is integrated to give #h B . The period of integration is maintained (switch 38 open) until the aircraft has climbed back to its original altitude (16, 24, Fig. 1) by means of a feed loop comprising summer 44. When #h B  is not being integrated, the value of #h B  is clamped to zero. #h B  is now compared to the radio altimeter altitude h R  in accordance with demarcation line 55, Fig. 3. The actual signal compared with #h B  in difference amplifier 46 is 0À107 h R +5. The result of this comparison is also fed as a second condition input of AND gate 52. Two further condition inputs are enabled when 700>h R >50. A final condition input is enabled when a logic circuit 56, 58, 62 determines that the aircraft is in a take-off mode. Logic 62 also produces a signal keeping switch 38 open in the event of a landing abort, and aircraft is in take off mode h R >50 ft, any "latent" warning signal is then allowed through.

Abstract: 1,029,561. Spray-producers. SECRETARY OF STATE WAR DEPARTMENT. April 5, 1963 [Jan. 8, 1962], No. 646/62. Heading B2F. A device for spraying liquid over a wide area into an external gas stream, e.g. the slipstream of an aircraft comprises outer,tubes 1, 3 around a concentric inner tube 2, pressurized liquid and gas feed tubes 4 and 5 connected to tubes 1 and 2 respectively, and two circumferential collateral slits 6 and 7 formed between the outer tubes 1 and 3 and separated by the flange 8 of a screw-threaded part 9 fitted between the tubes 1, 2 and 3. The tube 3 is screw-threaded on to the part 9 and the part 9 is screw-threaded on to the tube 2 so that the width of the slits may be adjusted. The tube 3 is closed at one end by a gas-tight plug 10 and the device is fitted with a streamlined nosepiece 11 which in operation forces the oncoming external gas stream which advances in the direction of arrow C. In operation the pressurized liquid emits through the slit 7 in the direction of arrow A whilst the gas-in this case air-discharges through the slit 6 in the direction of arrow B. The emergency liquid is virtually unpacked by the air and forms a dispersing cone in the angular direction of arrow B and is then immediately blown by the external gas stream in the direction of arrow C. The impact of this external stream completes the atomization of the sprayed liquid.
