Title: Improvements in or relating to mechanism for feeding strip material
Inventor: MAYER CORNELIUS GRAHAM
IPC: G03B19/18
Filed: 1957-06-18
Abstract: 871,150. Combined sound and picture apparatus. R.C.A. GREAT BRITAIN Ltd. June 9, 1958 [June 18, 1957], No. 19188/57. Class 40 (2). [Also in Group XVI] In a mechanism for feeding a strip in opposite directions between reversible rotary members, a rotor assembly with substantial rotary inertia is arranged between said reversible members and is rotated by the strip in one direction while passing over a drum comprising part of the said rotor assembly, and means are provided other than the strip for driving the rotor assembly in reverse direction at a speed such to maintain tension in the strip between the said rotor and one of the said rotary members. The embodiment describes a sound film projector in which the film is drawn through a picture gate by sprocket wheels 1 and 12 between which the film passes over a sound drum 5 mounted on a shaft 8 carrying a flywheel 11. When it is desired to reverse the drum to run back to a previous position on the film, a lever 14 is moved counterclockwise, as viewed in Figs. 3 and 9, to effect a reverse drive of the sprockets and spools. At the same time, a pin 17, Fig. 12, on a plate 16 controlled by lever 14 moves an arm 16A, through a snap-action spring 16C, to a position in which a link 22 moves a bell-crank 20 to a position which permits a slide bar 24, Fig. 2, carrying a stepped jockey pulley 29 to establish a driving connection between a driven wheel 30 and the flywheel 11, so that the latter is driven in reverse direction. The ratio of the gearing is so arranged that the speed in reverse direction is about 4% greater than in the forward direction in order to avoid bunching and accumulation of film between sprocket 12 and sound drum 5.

Abstract: 765,863. Electric motor wheels. LETOURNEAU, Inc., R. G. Aug. 15, 1951 [Aug. 23, 1950], No. 19240/51. Classes 79(2) and 79(3). [Also in Groups XXIV and XXXIV] A steerable vehicle wheel 2 is mounted by bearings 9 on an extension 10 of the frame 28 of a driving electric motor associated with an electromagnetic brake 38 and is driven through helically - toothed reduction gearing. A helical ring gear 8 attached to the wheel 2 is engaged by pinions 166 on two countershafts 135 (only one of which is shown), a driving pinion 85 being mounted on a long motor shaft 39 so that it floats between the countershaft gears 162. The outer bearings 161 of the countershafts are adjustable to provide, through the helical engagement 166-8, angular adjustment of the gears 162 to swing the shaft 39 to a central position. The countershafts 135 are mounted between interconnected front and rear plates 121, 122, the plate 122 being splined on the extension 10 and clamped by a nut 145 which has teeth engageable by a wrench 148. The plate 121 has diametrically-opposed threaded openings adjustably receiving the bearings 161 and after adjustment to centre the shaft 39 each bearing is locked by clamping together a split portion of the plate 121. A jig, Figs. 10, 11 (not shown), may be bolted to the plate 121 to indicate the central position of the shaft 39. The brake 38 comprises interleaved discs splined alternately to a hub 48 on the shaft 39 and a drum 40 fixed to the motor frame 28. A plate 53 of magnetic material is normally urged by springs 54 to press the brake discs against an adjustable ring 44 and engage the brake, but is retracted by a series of magnetic coils to release the brake when the motor is energized. The ring 44 is locked in adjusted position by a tapered stud engaging a split portion of the ring. The brake end of the shaft 39 is splined to the rotor 72 of the motor, and has a tapered ridge which is pulled against the splines by a nut 83. The armature coils 70 are supplied through a commutator 69 engaging a brush unit, Figs. 4, 5 (not shown), on a fibre disc 66. The plates 121, 122 may be so oriented that both wheels 162 dip into oil in the case 89. The motor frame 28 is supported on a vehicle by ball joints B held between bolted-together socket halves, and brackets (not shown) on the frame 28 provide means for steering. A pneumatic tyre is retained on the wheel 2 by a removable rim 4 held by a locking ring, and by a rim 3 held against a welded bead so that it is removable after the rim 4 and the tyre have been removed. A flexible valve stem 18 is attached to the inner tube. The vehicle speed and power range may be varied by the use of different tyres, a variable speed D.C. motor, and a selective gear ratio, the gear ratio being changed, while using the same gears 162, by replacing the shafts 135 and the ring gear 8. Specifications 741,921 [Group XXXIV], and 765,864 [Group XXIV], are referred to.

Filed: 1955-07-04
Abstract: 785,707. Transponder apparatus; radio navigation. STANDARD TELEPHONES & CABLES, Ltd. (International Telephone & Telegraph Corporation). July 4, 1955, No. 19323/55. Drawings to Specification. Classes 40 (5) and 40 (7). The duty cycle of the transmitter of a transponder beacon is maintained approximately constant by using the thermal pulse noise of the I.F. amplifier of the beacon receiver to pulse modulate the transmitter in the absence of interrogating signals for a spurious operation equivalent on the average to the desired duty cycle; and automatically reducing the gain of the I.F. amplifier in accordance with the rate of occurrence of any guinine interrogation pulse signals received. The output of either the I.F. amplifier itself, or of the detector following the amplifier, or of the transmitter modulator, is integrated to control the screen grid voltage of the I.F. amplifier so that it has a high gain in the absence of genuine signals, and the gain is reduced as more and more signals are received and hence less and less spurious pulses are transmitted under such conditions.

Title: An improved catalytic process
IPC: C10G11/18
Filed: 1944-10-09
Abstract: <PICT:0603082/III/1> In a process for the catalytic conversion of hydrocarbons of the kind in which a suspension of hydrocarbons and catalyst is passed through a reactor and the catalyst is separated from the cracked products mainly in cyclone separators followed by separation of residual catalyst by scrubbing the vapours with a condensate oil obtained therefrom, the oil is separated from the catalyst by filtration, by settling, or centrifugally and the separated particles are returned for use in the process, the oil being rejected.  In Fig. 1 the regenerator 52 is mounted above the reactor 18, regenerated catalyst being returned through an aerated stand pipe 92 to mix with the feed entering through a pipe 12 having a distributer plate 16.  The main portion of the catalyst is separated in a cyclone 24 situated within the reactor.  The vapors pass thence to a tower 28 from which vaporous products pass overhead through cooler 110 to gas separator 112 while heating oil and cycle oil fractions are withdrawn through 122 and 124.  The bottoms are recycled through cooler 136 as scrubbing medium and part of the oil with entrained catalyst is withdrawn through cooler 140 to a filter 142 where the catalyst particles are separated from the oil and passed to a mixer 148 where it is mixed with a portion of the crude feed and the mixture passed through line 156 to the reactor.  The catalyst may also be fed through line 156 to the regenerator 52.  In a modification (Fig. 2, not shown), the reactor and regenerator chamber are placed side by p  side, and the catalyst and vapours are removed therefrom together and separated in a plurality of cyclone separators; residual catalyst is separated from the scrubbing oil in a Dorr thickener. Specification 547,048 is referred to.

Abstract: 965,883. Cathode-ray tubes. RAULAND CORPORATION. May 16, 1963 [May 17, 1962], No. 19443/63. Heading H1D. In a high transconductance electron gun, e.g. for use in a television receiver, in which the control electrode 20, Fig. 2, has an aperture 31 small relative to the emitting surface of the cathode 19 and has a spacing from the cathode which is smaller than the thickness of the control electrode at the aperture, the cathodecontrol electrode space is filled with insulating material 34 except for a region 35 of diameter not less than 1.05 times the diameter of the aperture in order to avoid disturbing effects due to surface charges. The insulation may be a coating on the control electrode, an apertured cup placed over the closed end of the cathode, a ring-shaped insulator of mica or steatite or a protrusion on the cathode formed by spraying on several layers of insulation while masking off the central emitting area. A mesh grid may be fitted across the aperture as at 33 in Fig. 6 where a ring-shaped insulator 39 is formed on the shoulder 43 of a cathode which has a protruding central area 41. The insulator is preferably made of spongy or porous material, e.g. of aluminium oxide, magnesium oxide, barium oxide, zironium oxide or titanium dioxide, to minimize heat loss.

Filed: 1972-04-27
Abstract: 1367991 Information storage and retrieval AMPEX CORP 27 April 1972 [28 April 1971] 19534/72 Heading G4H Control commands (for, e.g. an audiovisual educational programme) are incorporated in an information storage and retrieval system in the form of control words whose digits are represented by different numbers of cycles of a signal having a frequency of less than 100 Hz (e.g. 55 Hz), each word being superimposed on information-bearing signals in an audioprogramming console 30 during storage and separated therefrom by a detector 56 during retrieval. Each word consists of an identity bit (9 cycles) followed by two " class of data " bits and seven " data " bits (binary 1, 0 being represented by 6 and 3 cycles respectively); the " class of data " bits serve to separate the commands into " picture ", " video message ", " function " and " special " codes. Data is fed into a computer 26 from a teletype 28 ; the information-bearing signals are fed from here via an encoder 34 to a recorder 32 and are monitored via headphones 40: when a control word is needed it is summoned from 26 by selector switch 42 and fed to a parallel track of recorder 32. The two tracks are then combined at 36 and recorded on one track of recorder 38. During retrieval the combined signals are fed from a buffer 64: the information-bearing signals are detected by a filter 54, and the control word causes a tone detector 56 to transmit data and clock signals to a register 66 whose output is directed by logic 68 to the appropriate latch 70 to provide the required control 72. A computer (e.g. 26) may replace 66-70. Input apparatus 26, 28 may be replaced by a switch-operated code generator 62, Fig. 4 (not shown), in which case the information bearing signals are prerecorded in 32 and the control word is fed directly to 36 from (62) and encoder 34.

Title: Typewriter tabulator mechanism
IPC: B41J25/18
Filed: 1951-08-21
Abstract: 711,711. Typewriters. JARDINE, Ltd., J., and HARDY, F. S. Oct. 27, 1952 [Aug. 21, 1951], No. 19649/51. Class 100 (4). Tabulating mechanisms.-Tabulator stop levers 1 of a typewriter are raised to their operative positions to engage with tabulator stops 16 on the carriage of the machine by springs 9 and are normally held in an inoperative position against the action of the springs by spring loaded pivoted arms 3 operated from tabulator keys. After operation by its tabulator key and pivoting of the arm 3, the particular stop lever 1 moves upwardly by means of the spring 9 and remains there until engaged by a tabulator stop 16. During actuation, an extension 10 of the arm 3 is latched by a notch 15 in a plate 13 slidingly mounted on a slotted plate 12, and keeps the stop lever 1 raised until the next projected column stop 16 reaches the stop lever 1. The stop lever is thereby tilted sideways and a rearward lug 19 engages the latching plate 13 which slides to release the arm 3: since the spring 8 biasing the arm 3 is stronger than the spring 9, the parts return to normal. When it is required to skiptabulate, an additional key is operated according to the number of columns to be skipped. These keys operate an associated plunger 33-36, Fig. 4, which engages a lever 32 driving a pinion 31 amounts corresponding to the number of stops to be skipped. Pinion 31 drives a toothed crank 30 engaging a slot in a racked slide 27 biased to the left, Fig. 3, by a spring 50. The slide 27 is formed 'with slots 39 normally accommodating cams 38 formed on the edge of a locking bail 25, and movement of the slide engages the cams 38 and pivots the bail 25 into notches 28 in the stop levers 1 to prevent the latter moving into operative position. Movement of the slide 27 also causes a tumbler 43 to pivot and move a pawl 45 thereon into position to engage the column stops 16. When a stop 16 engages the pawl 45 it rotates a pinion 41 engaging and returning the toothed slide 27 one step. This continues with each engagement of a column stop 16 until the slide 27 is returned to normal where the cams 38 re-enter the slots 39 and release the locking bail 25 which in turn releases the stop lever 1. The bail 25 is of a length to coact with all the denominational stop levers 1. The skip-tabulator keys are arranged in a vertical portion of the typewriter frame just above the keyboard.
