Abstract: 1,149,512. Reistors. WELWYN ELECTRIC Ltd. 27 Sept., 1967 [27 Sept., 1966], No. 43028/66. Heading H1S. [Also in Division C7] A precision resistor comprising an insulating former has deposited thereon an electrical resistance film of a nickel-phosphorus alloy having a surface resistivity in the range of from 0À01 ohm to 1 Megohm per square, said alloy containing from 5 to 20% by weight of phosphorus, said film having a thickness of at least 150 and the root-mean-square deviation of film thickness between different samples of area with a dimension greater than 0À01 cm. x 0À01 cm. being at most 8% of the mean thickness at the lowest resistance value and at most 4% at the highest resistance value. In a process for producing such resistors, and which is used to produce simultaneously a quantity of resistors, formers of, e.g. porcelain, steatite, alumina or other ceramic or plastics material, are cleaned and activated by rinsing in a solution of a stannous salt (i.e. stannous chloride) which may contain hydrochloric acid, rinsing in water and then rinsing in a solution of a palladium salt (i.e. palladium chloride), which may contain hydrochloric acid, to deposit at least a uni-molecular layer of palladium on the former, washing the former and then treating it with a reactivating solution containing from 0À1 to 2À5% weight/ volume of sodium hypophosphite or an equivalent amount of other water soluble hypophosphite (i.e. alkali or alkaline earth metal hypophosphite such as potassium- or calcumihypophosphite), and from 0À00005 to 0À005% weight/volume of nickel salt in solution at a temperature suitable for deposition of the nickelphosphorus film, and for a time sufficient to restore the activity of the palladium layer, then effecting electroless deposition of the nickelphosphorus film, and stabilizing the film by heating. The resistivity of the film depends on the substrate, activity of the palladium film, temperature, time of deposition as well as the concentration of nickel and phosphorus. Phosphorus can be removed from the film by washing with alkali solutions. The value of the resistor is adjusted after deposition by known methods, and one or more insulating layers, e.g. pigmented variable prepared from a silicone lacquer, followed by another layer, e.g. a pigmented varnish prepared from an epoxy lacquer and hardener, are finally applied. A number of examples and other details are described.

Abstract: 442,538. Calculating-machines. SOC. ANON. SANDERS, 50, Rue Benoit-Malon, Gentilly, Seine, France. Aug. 9, 1934, No. 23068. Convention date, Sept. 19, 1933. [Class 106 (i)] A calculating-machine has a plurality of groups of totalizers, any one totalizer being selected for addition or for total taking by cams on a travelling carriage, a common engaging link for all the totalizers of a group, a single actuating member for all the links, and a single key controlling the actuator for taking a total from the selected totalizer. The invention is shown applied to a machine of the kind described in Specification 28253 /08, [Class 106], and having two groups each comprising three totalizers, A3, A5, A7 and A4, A6, A8 respectively. The totalizers are engaged with racks at the proper times for ordinary actuation and for total and sub-total taking by the rocking of cranks M3-M8 from a single actuator comprising a " flying lever " 7 pivoted on a plate 6 secured to the mainshaft A. Two links 9a, 9b are pivoted to the flying lever 7 and to links 13a, 13b pivotally carried by crank-arms 10a, 14b, the links 13a, 13b thus being moved at each operation. Pivoted to the links 13a, 13b are levers V3-V8, Fig. 3. Each such lever is controlled by a mechanism as shown in Fig. 2. Each lever, here designated V, is normally withheld from engagement with a pin M<1> on the crank M of the corresponding totalizer by a pin P<11> on a bar P held in its right-hand position by a spring 23. When a cam 16 on the carriage rocks a lever 17, the bar P is moved to the left by a link 19 and lever 20, the lever V then engaging the pin M<1> so that, upon the subsequent movement of the links 13a, 13b the crank M is rocked to move the totalizer into engagement with the racks. The amount set on the keyboard is thus entered into the selected totalizer. Total-taking. There is one total key 1 for the six totalizers A3-A8. When this is depressed the movement of the flying lever 7 is modified by known means and a total is taken from the totalizer selected by the carriagecontrolled mechanism described above. Sub-totals. The total key 1 may be replaced by a sub-total key acting in known manner.

Abstract: 1,207,639. Control of D.C. motors. HONEYWELL Inc. 8 Sept., 1969 [13 Sept.; 1968], No. 44316/69. Heading H2J. [Also in Division G1] When a photo-sensitive resistor 15 is illuminated more than element 16, a control signal appears across terminals 36, 37, which is in phase with the voltage across supply terminals 38, 39, the magnitude of the signal being dependent upon the inequality of illumination. During half-cycles of the supply voltage in which terminal 39 is positive with respect to the terminal 38, transistor 30 is turned-on to fire S.C.R. 31 whereby coil 34 is energized to open contacts 35. Motor 18 is then energized and a light beam is moved towards a balance position in which it illuminates the elements 15, 16, equally. During periods in which the terminal 38 is positive with regard to the terminal 39, contacts 35 are closed and armature 19 is short-circuited so that the motor is alternately energized and braked in synchronism with alternations of the supply voltage. When the element 16 receives more illumination than the element 15, the control signal across terminals 36, 37, is in anti-phase to the voltage across terminals 38, 39. The transistor 30 conducts to fire S.C.R. 32 during periods when terminal 38 is positive with regard to the terminal 39. The motor 18 is now energized in reverse to restore the balanced condition, contacts 35 being closed when S.C.R. 32 is not conducting. The motor may be associated with a photographic projector having an automatic focusing arrangement, slide 2 being illuminated by lamp 3 through infra red filter 5, and condensing lens 6. Light passes through the slide and a projection lens 7 on to a screen, the lens being axially adjustable in holder 8 by knob 10. Light also passes from the lamp 3 and mirrors 11, 12, lens 13, to the slide 2 from which it is reflected and focused by lens 14 through an infra red pass filter on to the photo-sensitive resistors 15, 16, which are prevented from responding to light other than infra-red. The motor 18 is coupled to holder 8 through worm gear 22, worm-wheel 23, and cam 24 which is positioned between projections 25, 26. The lens 7 is initially focused manually, at which time the elements 15, 16 are illuminated equally. Any subsequent movement of the slide 2, or any difference in the position of subsequently inserted slides, causes the balanced condition to be upset, whereupon the motor 18 responds to restore the balance.
