Abstract: 859,943. Follow-up devices. IGRANIC ELECTRIC CO. Ltd., and TAYLOR, J. R. March 7, 1957 [March 1.4, 1956], No. 7969/56. Class 40 (1). In a follow-up device for selecting the future condition of an adjustable device, e.g. the distance between the rolls of a steel mill of the type in which the position of the movable roll is varied by a screw-down device driven by an electric motor responsive to unbalance between the outputs of two potentiometers, one corresponding to the position of a preselector handle and the other to the position of the movable roll, the wiper arm of the presetting potentiometer does not move into a position of correspondence with the handle until a brake is released. As shown, the shaft 14 on which the wiper arm 7 of the pre-setting potentiometer 9 is mounted, is normally braked by a brake 15. Handle 2 is moved into one of a number of discrete positions against the action of a coil spring 22 exerted through arms 20, 21. Closure of a switch 3 energizes a magnet coil 16, thus releasing the brake 15, whereupon the shaft 14 and the wiper arm 7 are moved by the spring 22 into positional correspondence with the handle 2. The handle 2 and the switch 3 may be located remotely from one another for actuation by different operators.

Title: Air Operated Price Marker.
IPC: B41F17/16
Filed: 1967-02-21
Abstract: 1,150,240. Air-operated marking device. KWIKMARK Inc. 21 Feb., 1967 [5 Aug., 1966], No. 8208/67. Heading B6C. An air-operated price marker comprises an air cylinder, a marking device connected to the piston-rod of the cylinder, an air-actuated control valve for the supply of air to the cylinder, and a lever which engages an article to be printed and operates a trigger valve which supplies air at a low pressure to actuate the control valve. Fig. 2 illustrates a marker according to the invention, wherein a housing 6 carries a printing unit for marking an article 9, e.g. the end of a can; the printing unit comprises a vertically reciprocable frame 10 which is provided with studs 12 sliding in slots 14 in the housing 6. A cross-bar 16 has a slot 18 which receives a screw-threaded stud 20 mounted on top of a printing head 22, the slot permitting positional adjustment of the head which consists of a plurality of rubber belts 26 carrying type, the type positions being selectable. On the back wall 30 of the housing, an air cylinder 32 connected to two pipe-lines 34, 36, contains a piston 38 to which is secured a rod 40 which passes through a plate 44 carried on cross-bar 46; a compression spring 50 lies beneath the cross-bar 46 and is held on threaded portion 42 of the piston-rod 40 by a locking nut 52. Thus the frame member 10 and the printing head 22 can move downwards against the action of spring 50 under the inertia supplied by pistonrod 40 and continue moving downwards after the piston completes its downward movement. Inking unit.-An inking roller 54 is suspended by its axle 56 between a pair of plates 58 pivoted to the housing 6 ; the plates 58 have angled slots 60 through which the studs 12 extend. As the studs are also secured to the vertically reciprocable member 10, when the latter moves vertically, the slots 60 will cause the roller 54 to describe an arcuate movement between an inking pad 62 and the type-bearing portions of the belts 26 (also Fig. 3, not shown). Compressed air system.-A trip lever 142, when engaged by an article to be printed 9, actuates a trigger valve 116 which is normally biased to a closed position; when so actuated, the valve 116 admits air at a low pressure to the inlet of control valve 64. This valve 64 has outlets which are connected via conduits 34 and 36 to either side of the piston 38 in main cylinder 32 ; normally, the valve 64 admits compressed air to conduit 36, thus maintaining the printing head in its uppermost position, but, when actuated by trigger valve 116, the control valve admits compressed air to conduit 34 instead, forcing the printing head to move vertically downwards on to the article 9.

[Class 6(i)] A seed-sowing machine comprises a wheeled hopper 3 within which is a rotatable brush 5 adapted to eject seeds through an apertured disc 4 co-operating with a rockable closure plate 8, the plate being mounted on a spindle 7 carrying a toothed member with one of a series of toothed wheels. In the form shown, an axle 1 carrying land wheels 2 passes through, and supports, the hopper 3, the rotatable brush 5, mounted on the axle 1 within the hopper. ejects seeds therefrom through one of a series of holes of various sizes in the apertured plate 4 rbtatably secured to the rear wall of the hopper. The plate' 8, mounted. on one end of a rockable arm 6, periodically closes the appropriate aperture in the plate 4 to interrupt the flow of seeds. The arm 6 is fixed to the spindle 7 which is rocked by the engagement between a toothed member carried by the spindle and one of a series of toothed wheels mounted on the axle 1. The ejected seeds pass down a tube 13 and enter the ground behind a tine 14 integral with the tube. An arm 15 pivoted at the rear of the hopper carries furrow-closing shares 17, a soil-consolidating roller 16 and drill-marking tools 20. A soil-levelling device 18 is mounted on the front of the hopper to precede the tine 14. The wheels 2 drive the axle 1 through freewheel clutches (not shown).

Drawings to Specification. [Class 37] In a rectifier comprising two electrodes of different electron-emissive power separated by a thin intermediate layer of solid non- conducting material, an additional layer of specific resistance higher than that of the semi-conductor, or electrode of lower emissivepower, is interposed between this electrode and the nonconducting layer. This additional layer preferably comprises a substance containing at least one of the ingredients from which the semi-conducting electrode is made. Thus in a rectifier using cuprous oxide, as the semi conductor, the surface is reduced or electrically treated to form a layer of higher specific resistance In another example silver sulphide is superficially treated with sulphur. In a selenium-aluminium oxide compound plate the selenium in the surface layer may be removed by volatilization giving a thin, more highly resistant layer. Specification 378,444 is referred to.
