Title: Television camera arrangements
IPC: H04N5/228
Filed: 1972-10-12
Abstract: 1444915 Cathode-ray tube circuits EMI Ltd 14 Sept 1972 [12 Oct 1972] 47061/72 Heading H4T In an arrangement for reducing the effect of "lag" in the output signal of a television pick-up tube 3, i.e. failure of the scanning beam to discharge completely all the elemental charges on the tube target 2, the latter is scanned with a raster in which each line is scanned twice in successive line periods of a two field interlace the video signals generated during the first scan of each pair of scans (switch 6 closed, switch 13 on conductor 14 and switch 10 open) being supplied to the input of a one line-period delay 11 and to the camera output terminal 12 whilst during the second scan of each pair (the switches being in the position shown) the delayed signals are supplied to output terminal 12 and to an inverter 9 the output of which intensity modulates the tube beam via cathode 8. Thus any residual charges remaining on the target at the end of the first scan of each pair of scans is removed during the second scan of that pair so that, in the subsequent field, the elemental target areas will charge-up proportionally to the incident light. The video signal output at terminal 12 provides signals indicative of a complete scanning raster but of half the normal vertical resolution since each line is repeated once. Instead of line sequential correction the tube output signal may be sampled at a highfrequency (dot-frequency) and the correction applied before the beam moves to the next dot by means of a spot wobble technique. Bias lighting may also be employed. The scanning is effected in a "two field interlace" raster of the kind described in Specification 1,426,434 the scanning being in the line sequence 1, 1; 5, 5; 9, 9 &c. during the first field and in the line sequence 3, 3; 7, 7; 11, 11; during the second interlaced field.

A transport system has transport units driven and guided around guide means 1, Fig. 1, including zones BB<SP>1</SP> to EE<SP>1</SP> and HH<SP>1</SP> to KK<SP>1</SP>, wherein the units are driven at high speed and in end to end relationship, zones AA<SP>1</SP> to LL<SP>1</SP> and FF<SP>1</SP> to GG<SP>1</SP> wherein the units are driven at low speed in side by side relationship, and zones AA<SP>1</SP> to BB<SP>1</SP>, EE<SP>1</SP> to FF<SP>1</SP>, GG<SP>1</SP> to HH<SP>1</SP> and KK<SP>1</SP> to LL<SP>1</SP> through which the units are decelerated or accelerated and moved endwise and sidewise whilst maintaining the units substantially constantly orientated. Each unit comprises a platform pivoted at 9, 10, Fig. 3, to bogies 4g, 5g having wheels 6, 7, 11, 12 positively guided by rails 2, 2<SP>1</SP> and wheels 8, 13 bearing on rails 2, 2<SP>1</SP>. Track extensions 14, 14<SP>1</SP>, Fig. 1, support wheels 8, 13 as the units move from a fast zone to a slow zone or vice versa whilst the bogies rotate on pivots 9, 10. The units are propelled by variable pitch screws, Fig. 6 (not shown), to match the desired speeds through the various zones. The units have side and end couplings as disclosed in Specification 1,034,968. Each unit can be divided into compartments by partitions 65, 55, 67, Fig. 11 (not shown), which have hand grips as have ends 62, 63, side portions 60a- 60d and 61a-61d are movable vertically and in the slow speed zone the portions are lowered so that passengers can step from a unit 70, Fig. 14 (not shown), on to a stairway 90-93 before the unit passes beneath the stairway, the walls and partitions 85-89 passing through slots in walls 80-84 of the stairway. The side partitions can be automatically locked in the raised position when the units are outside the slow speed zones. In Fig. 15 (not shown), the units pass beneath stairways having separate stairs for passengers getting on and leaving the units. The fast zones may be adjacent another transport system, Fig. 15 (not shown), and the speeds of the systems can be matched whereby the side portions can be lowered and passengers can transfer from one system to the other in the high-speed zones. In an alternative form of slow-speed zone, Fig. 10, the unloading/loading section 49 is connected to link sections 47, 48 by loops 50, the units 51, 52, 53 moving upside down through section 49. This layout can be used when the second system has its tracks spaced closely together and can therefore run between the fast zones of Fig. 10.

Filed: 1964-11-20
Abstract: 4-Alkenyl or 4-substituted alkenyl derivatives of dibenzofuran of the general formula <FORM:1077086/C3/1> in which R, R1 and R2, which may be the same or different, are hydrogen, or an alkyl aryl, alkaryl or aralkyl group and n is an integer from 0 to 21, may be polymerized to give homopolymers or copolymers with olefines, e.g. pent-1-ene, ethylene and propylene.  The polymerization is effected under anhydrous non-oxidizing conditions, preferably in a liquid medium and in the presence of a polymerization catalyst.  Preferred catalysts are free radical catalysts, Lewis acids or Friedel-Crafts catalysts or Ziegler-Natta catalysts.  Examples are given of the preparation of homopolymers from (a) 4-vinyldibenzofuran, (b) 4-allyldibenzofuran; (c) 4 - methylallydibenzofuran; (d) 4 - (3-butenyl)- dibenzofuran; (e) 4 - (4 - pentenyl)-dibenzofuran; (f) 4 - (5 - hexenyl) - dibenzofuran; (g) 4 - (6 - heptenyl) - dibenzofuran; (h) 4 - (10 - phenyl - 10 - undecenyl) - dibenzofuran; and 4-(22-tricosenyl)-dibenzofuran; and a copolymer of 4-(4-pentenyl)-dibenzofuran and 4-(5-hexenyl)-dibenzofuran.ALSO:The invention comprises alkenyl derivatives (other than the vinyl derivative) of dibenzofuran of the general formula <FORM:1077086/C2/1> in which R1, R1 and R2 each represents a hydrogen atom or an alkyl, aryl, alkaryl or aralkyl group, and n is an integer from 0 to 21.  The compounds of the above formula in which n is 1 or 3-21 are prepared by reacting a monohalogeno alkene of formula <FORM:1077086/C2/2> in which A is a halogen atom with a 4-alkali metal substituted dibenzofuran.  Preferably the reaction is performed under anhydrous non-oxidizing conditions in a solvent, e.g. tetrahydrofuran, benzene, toluene, xylene, or an ether.  When n is O and R2 is H, i.e. in the preparation of 4-vinyl dibenzofuran, the vinyl group is introduced by reacting the alkali metal derivative of dibenzofuran with acetaldehyde and dehydrating the product. (Compounds in which n is O and R2 is other than H are prepared by using the corresponding carbonyl compound.)  When n is 2 a 4-(monohalobutyl)-dibenzofuran may be reacted with an amine, the product oxidized and the resulting oxide pyrolysed to produce the required compound or alternatively a 4-alkali metal derivative of dibenzofuran is converted into a 4 - (monohalobutyl) - dibenzofuran which is subjected to dehydrohalogenation to yield the desired compound.  The 4-monohalobutyl-dibenzofuran may be prepared by reacting a 4-alkali metal substituted dibenzofuran with a compound of general formula <FORM:1077086/C2/3> in which R, R1, R2 or A are as previously defined.  The 4-alkali metal substituted dibenzofuran compounds are prepared by reacting dibenzofuran or a functional derivative of preferably an alkylate or hydride, in a solvent under anhydrous non-oxidizing conditions.  Suitable alkali metal derivatives include sodium hydride, potassium hydride, ethyl sodium, ethyl potassium and n-butyl lithium.

Title: Positioning apparatus, e.g., for film strips
IPC: G06K13/30
Filed: 1964-11-23
Abstract: 1,056,040. Control of motors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 23, 1964 [Dec. 20, 1963], No. 47509/64. Heading H2J. [Also in Divisions B6, G2 and G5] In order to position a web so that a certain portion of it comes opposite a fixed point (there being an allowable positional error), the web is advanced by means of a motor 46 driven capstan approximately 95% of the total distance to the fixed point, and then in a series of steps each equal in length to the allowable error until the portion is opposite (or within the margin of error of) the fixed point. For each advance of the web, the motor is accelerated during the time the web advances half the distance, and then decelerated while the web advances the rest of the distance. The motor is controlled by a solenoid 40, the start pulse being transmitted via an AND gate (21, 33, 23) and a transistor 25 to the armature of the solenoid and, via a shot SS 1  and a trigger T 2  to disengage a brake 48 and to energize the solenoid core, thus passing potential to an inverter and an amplifier. After a predetermined time, SS 1  is turned off thus switching off the transistor 25 and causing the motor to decelerate. A tachometer feeds its output to a zero velocity detector. Whenzero velocity occurs, SS 2  is fired, transistor 59 is turned on, and the motor accelerates. When the single shot SS 2  falls, the transistor 59 is turned off and the motor decelerates. This is repeated until a photo - cell is activated by the portion of web reaching the desired position.
