Abstract: 1,084,494. Television and facsimile picture recording. RANK XEROX Ltd. May 14, 1965 [June 1, 1964], No. 20465/65. Heading H4F. Xerographic apparatus, Fig. 2, for recording television or facsimile pictures comprises a drum 17 bearing a photoconductive layer 56, Fig. 3, supported by a dielectric layer 50 on an earthed conductive member. 51 and, including electrically separate conductors 52, 53, 54 extending parallel to the drum axis. The ends of the conductors 15 engage a brush 13 whereby video signals to be recorded may be applied to successive conductors as, the drum rotates. A light source 31 is traversed back and forth adjacent the drum, the relative rate of traverse and, drum rotation being such the light makes one traverse as each conductor is brought into use. In response to the video signals and the change of conductivity produced in each elemental area by the light source a pattern of charges is created corresponding to the television or facsimile pictures. The charges are developed to a visual pattern by known apparatus 37 and the pattern is thereafter transferred to a record strip under the action of a high potential electrode 44 and fixed thereon by a heater 46. The charge pattern on the drum is then removed by exposure of the drum to an intense light source 25 whilst the electrodes are earthed by brush 20. The electrodes are also earthed by a brush 16 in the region following scanning by light source 31. Conductors 52, 54, 56 &c. may be embedded in dielectric 50 instead of being formed on the surface as shown in Fig. 3. In a modified construction, Fig. 5 (not shown), the earthed conductive member 51 is dispensed with and each of conductors 52, 54 &c. is replaced by two conductors, one of which is earthed. As an alternative to traversing light source 31 back and forth, a scanning light system based on a mirror drum, Fig. 6 (not shown), or rocking mirror may be used. Reference is made (without given details) to a drum system in which the photoconductive layer is removable and forms the base of the final picture. Reference is also made to the application of the invention to a flat bed scanning system.

Title: Improvements in and relating to counter zeroising and control mechanism for use especially in liquid dispensing apparatus
IPC: G06M1/28
Filed: 1940-01-11
Abstract: 544,218. Counting mechanism for petrol pumps. LODER, J. Jan. 11, 1940, No. 675. [Class 106 (i)] Motor driven counter mechanism in liquid dispensing pumps is provided with mechanical interlocking means for preventing the motor, after being stopped, 'from being started again till the counter has been disengaged from the meter, re-set to zero, and again engaged. The motor is switched on by a downward thrust of a slide 8 spring-lifted with its runner 7 against a cam 6 on a shaft 3 with a handle 4 to which a half-turn is given. The interlock disc 5, Figs. 1 and 2, has a spring pressed tooth 37 which can only clear the end of a lever 33, to allow the halfturn, when the other end of lever 33 lies in a gap 29 in a slide 26, which must thus first be drawn to the right by a pull on the knob 19 to cause the slide 26 to disengage the counter and reset it. The first part of the half turn raises, by means of a cam 42 on the disc 5, the spring- pulled end of lever 33 freeing the slide 26 from the other end 36 and allows the spring-pulled slide 26 to move to the left to engage the counter with the meter. The rest of the half-turn cams the slide 8 down to switch in the motor for the pump. After delivery, the pump is stopped by a reverse half-turn of the crank 4. A full-stroke ratchet 11 and pawl 12 enforces full half-turn each way. A modification according to Fig. 11 shows a sliding handle 102 for de-clutching the counter driving disc 115 from the liquid meter driven disc 118 and for re-setting through bevel gear 116, 119 the counter hands 105, 106, which at zero allow teeth 129, 130 on a lever 131 to rise and free at 133 the motor starting handle 101. A varied form of the lever 131 is also described. In a further modification, a single handle only is necessary being fitted with cam means 50, Fig. 10, to actuate the disengaging and zeroizing mechanism.

Molten metal is degasified by removing and degasifying successive small portions of a melt contained in a ladle, the degasified portion being returned to the main. bulk each time until the desired level of degasification has been attained. As shown, the apparatus for degasifying steel consists of a ladle 12, carried on truck 11 by platform 13 the vertical height of which can be adjusted by the hydraulic ram 14, and a vacuum vessel 4 with a refractory lining 2 and metal casing 1 connected to a vacuum pump 9 by the line 10. In operation, the ladle is positioned beneath the vacuum vessel 4 and is raised so that the end of inlet pipe 5 dips beneath the surface of the melt, the thin metal cone 8 serving to push aside the surface layer of slag before it melts. A vacuum is established in the vessel 4 and a small quantity of molten steel is drawn into the vessel and degasified after which the ladle is lowered sufficiently to remove the molten steel from the vessel 4 but keeping the outlet of pipe 5 beneath the surface of the melt. The sequence of operations is repeated until the melt in ladle 12 is degasified. The vacuum vessel 4 may be heated by resistance heating, carbon rod heating, induction, arc or glow discharge heating during the degasification process.

Title: Control systems for fuel systems for internal combustion engines
IPC: F02D7/00
Filed: 1973-01-06
Abstract: 1460013 Automatic control of fuel supply in IC engines CAV Ltd 18 Dec 1973 [6 Jan 1973] 890/73 Heading G3N A control system for the fuel supply of an  engine includes means for increasing the slope of the idling curve of fuel supply against speed by supplementing a demand signal below a predetermined speed. The control arrangement is similar to that shown in Specification 1416861 and the supplementary signal is produced by a transistor circuit similar to that used in Specification 1460014. In operation when the engine speed falls the voltage from transducer 15 rises to cause the transistors 51, 56 to have more equal conduction currents until at a predetermined speed transistor 64 is switched on to increase the current flow to amplifier 17 and thus increase the fuel supply for a given speed. It is stated that this change in the idling characteristic reduces the speed change of the engine when a load is applied, e.g. by engagement of an automatic transmission.
