Abstract: 955,829. Multiple key locks; barrel locks. AMERICAN HARDWARE CORPORATION. July 26, 1960, No. 25974/60. Heading E2A. A cylinder lock comprisises a housing 6, having an opening in which is rotatably mounted a key plug 10, at least one tumbled bore 16 which extends into a keyway in the key plug 10, and a series of tumblers in the bore 16, the arrangement of the tumblers being such that the lock is initially operable by a first key and at least one second key, but that after insertion of the second key the series of tumblers is changed by having at least one tumbler removed, and the first key is no longer able to operate the lock. As shown, a first tumbler bore contains a ball 17 and spring loaded tumblers 18, 19, 20, and 21 while each other bore contains tumblers 24, 25, and 26, the key plug being rotatable by any key which raises the series of tumblers until the surface between any two tumblers coincides with the peripheral surface of the key plug 10. There being three such surfaces between the tumblers 18-21 in the first bore, the lock may be operated by a permanent master key, a temporary master key and a service key. A disabling key 30 is used to render-the temporary master key inoperative by removing tumbler 19 from a bore 16. The key 30, Figs 6 and 7, is provided with a recess 31 on its lower surface, such that when the key is rotated through 180 degrees the tumbler 19 is urged by its spring downwardly into the recess 31, the key plug having a slot 32 to accommodate the tumbler. Further rotation of the key to its first position carries the tumbler 19 round in the key plug so that removal of the key then ejects the tumbler. The arrangement of the tumblers in the first bore 16 may be used in any or all of the bores. Specification 955,828 is referred to.

Void [Abridged as open to inspection under Sect. 91 of the Acts, March 22, 1934]. [Class 40 (iv)] Several arrangements are described for resiliently mounting the digit-bearing members of an impulse-transmitter so as to bear against the rear side of the finger disc. In one arrangement, Fig. 2, individual digit-bearing discs 6 are mounted on helical springs 9, attached to a back plate 5 which rotates with the finger disc 8. In a second arrangement, the discs 6 are replaced by a single annulus bearing all the digit indications. In a third arrangement, Fig. 6, the digit-bearing annulus 14 is mounted on the fixed casing 16 and to minimize friction may be formed with reduced bearing surfaces 18, as in Fig. 7. An enclosing ring 17, Fig. 6, prevents the entry of dust. The helical springs may be replaced by leaf springs or by a member with resilient arms 19, Fig. 8. The annulus 14 may be translucent so that the indications may be lit by light from behind and in this case the ring 17 may be transparent. The annulus 14 may be combined with a protective transparent member 21, Fig. 11, the two being held together by inner and outer rings 22.

Oct. 6, 1948, No. 26101. Convention date, Oct. 6, 1947. [Class 98 (ii)] Apparatus for the semi-wet development of photographic prints comprises a rotary feed roller, the surface of which is provided with capillary channels extending transversely to the roller axis, the channels being at such a small distance from each other than a substantially uniform delivery of a laterally continuous film of liquid is obtained, and an intermediate liquid-transfer roller or rollers for supplying liquid from a source of supply to the feed roller, a doctor blade being provided for co-operating with the intermediate roller or rollers for limiting the quantity of liquid transmitted to the feed roller. As shown, developer is applied to the strip 3 by a roller 1 consisting of a metal core coated with a synthetic material in which are provided helical grooves. The roller 7 dipping into the developer 10 and transferring developer to the roller 1 is engaged by a doctor blade 13 provided with recesses. The roller 7 may itself have helical grooves, and in this case the doctor blade may be smooth. In a modification, the blade 13 is replaced by a doctor roller, and one or both of the roller 7 and the doctor roller are grooved or pitted. The doctor roller may dip into the developer and transfer developer to a roller 7 not dipping into the developer, or both rollers may dip into the developer. As shown in Fig. 5, both sides of the film 3 are developed by use of a duplicate system of rollers. A series of rollers may be provided between the feed rollers 1, 1<SP>1</SP> and the developer baths 10, 101. The rollers may be of stainless steel, rubber, synthetic material, or glass. The apparatus may be combined with a contact-printing apparatus of the kind in which tracings and a continuous band of lightsensitive paper are passed over an internally illuminated glass cylinder, the speed of rotation of the cylinder being varied to vary the exposure.

The other dials 21 and 211 merely showing the gauge 14 in alternative positions. The air is supplied under pressure from a stabilizer 8, valve 9 and inlet 5, and back pressure is indicated by a pointer 13 on a scale 14 which serves to indicate the position of the rod 2 with respect to the sleeve 1. A control member 30 carried by the pointer 13 is movable into and out of the air paths from nozzles 27 and 28 fed from an air line 42 and interrupts or reduces their air-flow so that the range of movement of the rod 2 driven by means of a drive unit 38 controlled by air-flow variation in lines 36, 37 is therefore altered according to the position of the pointer 13 and control member 30 affecting control of the nozzles and also the airflow in the lines 36, 37. The distance apart of the nozzles is also adjustable by means of a spindle 33 and handle 34 to vary the range of movement of the rod 2. The whole apparatus may be used to indicate the relative position of the two parts 1, 2 or may be used to control their movement relative to one another. In Figs. 2 and 3 (not shown) the sleeve is movable over a fixed rod and in Figs. 4 and 5 (not shown) the relatively movable members comprise a sleeve surrounding a tube telescoping therein, the tube being closed at one end and having a series of longitudinally spaced holes the escape of air from which is regulated by the degree of telescoping. In Fig. 6 the two members are a U-shaped fixed part 53 having a chamber 4, and a rotatable disk 52 provided with a varying depth peripheral groove 56. In Figs. 8 and 9 (not shown) the grooved disk is fixed and an "L"-shaped surround containing the chamber 4 is rotatable around it.

[Class 125 (ii).] An apparatus for extracting corks from bottles comprises a screw 10 rotatably mounted in a head 8 carried by lazytongs 1, 1a, 1b, and a socket 4 which engages the neck of the bottle. The screw passes through a nutlike member 21 which is rotatably mounted in the socket 1. The member 21 is locked against rotation when the head moves towards the socket due to the engagement of the conical part of the member 17 with the socket, but is free to rotate when the head moves in the opposite direction. By this means the cork 5 when extracted is rotated by the member 21 and automatically unscrewed from the screw. A series of race balls 20, are provided in the member 17. The head of the screw 10 is locked by a cross-piece 11 when the cork is being withdrawn. A handle is provided on the end links 1a, and the links have interengaging segments 25.

[Class 35] Casings.-A rotary inductor alternator has a circumferentially adjustable field-magnet system which also carries the coils in which current is induced and the rotor consists of a number of star shaped members of magnetized or unmagnetized iron. In the form shown, the three-phase machine has three stator units, each comprising generating coils 23 on members 22 located between the ends of permanent magnets 20 held between a pair of rings 16 which can be adjusted circumferentially by means extending through slots in the glass or glass-lined casing 11. The rings 16 also carry contact rings connected to the coils 23 on which spring contacts rest. There may be more than two magnets per stator unit and instead of being permanent they may have windings 43 shown dotted. The rotor has three axially displaced sets of light equally spaced limbs 36 of magnetized or unmagnetized iron, the sets being angularly displaced according to the number of phases. An alternative construction for the rotor is shown in Fig. 9, a plurality of permanent magnets 45 being arranged in commutator fashion about a spider 46, the outer ends of alternate magnets having the same polarity. This modification is particularly suitable for high-frequency machines. The number of field magnet and inductor units may be other than three.
