Abstract: 819,556. Electromagnets. CURTISSWRIGHT CORPORATION. April 29, 1957, No. 13617/57. Class 35. [Also in Groups XXVI and XXIX] In an hydraulic speed governor (see Group XXXIX) the speed setting is remotely adjustable by a solenoid device which acts on a speedsensitive pilot valve P through a rod 42 and comprises an annular member with pairs of annular polepieces 44, 44<SP>1</SP> and 45, 45<SP>1</SP> with energizing coils 43, 43<SP>1</SP> embedded in moulded plastic envelopes 49 and an armature 41 with annular ribs 144, 144<SP>1</SP>, 145, 145<SP>1</SP> corresponding in spacing to the spacing of the polepieces. The coils 43, 43<SP>1</SP>, which may be connected in series or in parallel, are such that adjacent polepieces 44, 45 are of like polarity. A greater or lesser number of coils, tapped as required, may be provided. Stepped gauging surfaces 63, 64, 65 are provided on the outer parts of the solenoid device to facilitate adjustment by means of a screw 60 and locking screw 70 of the armature relative to the rod 42. Alignment of the gauging surfaces 63, 65 corresponds to the alignment of the polepieces 44 &c. with the annular ribs 144 &c. whilst alignment of the surfaces 64, 65 corresponds to the positioning of the armature relative to the fixed member when the armature is displaced to an extent to provide the desired biasing force on the pilot valve. Pin-and-slot connections connect the rod 42 with both the pilot valve and the armature so that the whole assembly is rotated to reduce static friction. End plates 51, 52 of the solenoid device in which the armature has bearings are made of non-magnetic material, e.g. bronze, and the journals 53, 54 of the armature may be chromium plated. In a modification, both the armature and the polepieces are made of annular rings which are clamped together to facilitate manufacture. Also, in addition to the armature being adjustable relative to the rod 42, the fixed member of the solenoid-device is vertically adjustable in the housing. Specification 550,568, [Group XXIX], is referred to.

Abstract: 1,246,341. Cassette machines; adapters. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 17 March, 1969 [19 March, 1968 (2); 21 March, 1968; 3 April, 1968], No. 13785/69. Heading G5R. An adapter, enabling a cassette to be used with a cartridge player for which it was not designed, comprises a head, a tape transport and insertion opening for the cassette and means for electrically coupling the head to the amplifier circuit of the player when the adapter is inserted in the player. The transport is either self-powered or driven from the player capstan. The adapter 21 is in the general form of an eight- or four-track endless cartridge and contains a spring-loaded 28 movable plate 26 carrying a capstan 34 and spool spindles 29, 30. A cassette is loaded on to the plate 26 and pushed in until held by a catch 38, whereupon the tape is pinched between capstan 34 and pressure roller 50, and record/playback and erase heads 51, 52 enter the cassette. A switching rod 71 operates switch 17 to energize the player when the adapter is loaded so that capstan 15 is driven, thereby rotating the adapter capstan 34 and spindles 29, 30 by a system of belts, pulleys and rollers. Release of catch 38 by knob 37 frees the plate 26 to disengage the capstan 34 drive and release switch 17. In this position, movement of knob 55 to right or left causes lever 53 to pivot about pin 54 and thereby engage roller 60 with roller 36 on capstan shaft 34, or roller 64 with roller 33 on spindle 30 to fast wind or rewind respectively, a slide 56 coupled to the lever 53 operating L-rod 68 to operate the switch 17. A record button 74 is operable, when a portion is removed from the cassette, to operate switch 75 and permit recording. Electrical connection to the player is made by contacts 73, contacts 13, or by capacitive or electromagnetic coupling with the player head 14. In a modification (Fig. 9, not shown) the switching arm 71 is replaced by a lug (80) which generates a switch (79) controlling the amplifier circuit of the player, and the adapter contains a motor energized from the player.

Abstract: 626,250. Checking shuttles in looms. HINDLE, T., and HINDLE, J. R. May 28, 1947, No. 14149, [Class 142 (iii)] A drop box loom is provided with a mechanism which reduces the spring pressure on the swells while the boxes are changing and while. the shuttle is being picked. Feeler levers 2 mounted on a stop rod 1 are urged against the swells 3 by a spring 5. The initial tension of the spring may be adjusted by a screwed connection 6. When the shuttle is about to enter the box the portion h of a cam mounted on the crankshaft moves the lever 13 which turns the bell crank lever 8 by means of a rod 15 to increase the pressure on the swell. This increase in pressure may be adjusted by raising or lowering the end 16 of the rod 15 in the slot 8b. When the shuttle is to be picked and also when the boxes are changing the portion g of the cam allows the lever, 8 to return to its initial position and the pressure on the swell is reduced.
