Title: A device for tuning a radio or television receiver
IPC: H01C10/40
Filed: 1969-05-08
Abstract: 1,224,853. Push-button tuner units. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 May, 1969 [10 May, 1968], No. 23571/69. Heading H3Q. [Also in Division H1] A device for tuning a radio or television by capacitance diodes and potentiometers comprises a plurality of push-buttons 1, each axially displaceable for switching into a tuned circuit the associated potentiometer 41, a nut 47, 49 supporting the potentiometer tapping contact 51, one of a further nut 25, 27 or screw-threaded bolt 21 coupled for rotation with the button and being axially displaceable with the button to drive a station indicator 35, common to all buttons, such that when the nuts are moved to contact stops the nuts can jump back by one turn of its associated screw thread substantially simultaneously. This enables the station indicator to remain correctly adjusted for the setting of the associated potetiometer if the push-button is rotated beyond the end stops. When the button 1 is pressed in it releases any previously pressed button. The slider 51 and station indicator 35 can then be adjusted by rotation of the pressed button 1 via gearing 15, 19 and 17. The gears 17 and 19 may be metal or synthetic material and gear 15 may be synthetic resin. The nuts 25, 27 and 47, 49 have U-shaped springs 25, 49 which enable them to jump back one turn of their associated thread together if the button 1 is rotated beyond the end stop position where the nuts 25, 27 and 47, 49 contact end stops 29 or 17 and one end wall of the potentiometer synthetic resin casing 43. Alternatively the rotatable screw-threaded bolt 21 may be attached to the free end of rod 3 so as to cooperate with the non-rotatable nut acting to drive the station indicator. In a further modification a bolt can be made non-rotatable to the head 23 with the nut rotatably coupled to gear wheel 15 so that the nut acts to move the station indicator. The axially displaceable member 9 can be of plastics and the potentiometer may have a resistive layer 45 such as carbon. The station indicator U-shaped bracket 35 is spring-biased towards gear 17 and may be coupled to a pointer or drum.

Patent GB-754897-A (GB)
Title: Improvements in or relating to method of making a metal alloy
IPC: C22B23/02
Filed: 1954-08-19
Abstract: An alloy is produced by mixing a molten slag containing a compound of an alloying metal with a molten metal which is reducing towards the compound, regulating the temperatures of the molten slag and the molten metal so that upon mixing the metal is cooled to a mass of comminuted particles which reduce the compound and upon which the alloying metal deposits and separating the mass of particles from the remaining molten slag. Thus to prepare an iron-nickel alloy, an iron ore containing nickel oxide is melted in a rotary furnace and poured into a receptacle.  A ferrous metal, e.g. pig iron or partially refined steel, is then poured into the receptacle, the temperatures being regulated so that a mass of iron particles coated with nickel is formed in the slag which is then poured off.  The alloy produced may be refined, e.g. in an open-hearth furnace, to produce an alloy steel.  If the iron ore used contains ferric oxide this is preferably reduced to ferrous oxide in the melting step.  The preparation of alloys containing copper and molybdenum is also referred to in the Specification.

Title: Improvements in or relating to bolt-action rifles
Inventor: PERRY CLAUDE ALFRED
IPC: F41A17/64
Filed: 1952-04-17
Abstract: 730,179. Safety devices for bolt-action rifles. BIRMINGHAM SMALL ARMS CO., Ltd. July 17, 1953 [April 17, 1952], No. 24186/51. Class 119. In a bolt action rifle the bolt comprises front and rear hollow parts 2, 1, Fig. 1, rotatably secured together with a firing pin 5 and cocking piece 7 located within the bolt, a cam 17 mounted on the rear part 1 for rotation about a transverse axis normally allowing free movement of the clocking piece as shown in Fig. 1 but which, on rotation by means of a thumb piece 19, when the bolt is in cocked position, engages in a groove 15 in the rear part 3 of the cocking piece as shown in Fig. 2 to prevent forward movement thereof. The rear part 1 is screwthreaded into the front part 2, and the rear depending portion 3 of the cocking piece provides a shoulder 23 for abutting against a sear 21 when the bolt is cocked and prevents rotation of the rear part 1 of the bolt. On cocking the rifle the front part 2 is rotated with respect to the rear part 1 and the whole moved rearwardly. On movement of the cam 17 to safety position, the cam also causes the cocking piece 7 to move rearwardly a short distance sufficient to move the shoulder 23 away from the sear 21 which rides upwardly and engages within a narrow groove 25, Fig. 2, in the rear end of the front part 2 of the bolt and thus prevents rotation of the front part when the rifle is cocked and safety catch applied. Alternatively, the rotation may be prevented by a plunger operated by the cam 17 to engage with a hole in the front part of the bolt. An arcuate chamfered track over which the thumb piece 19 moves is provided on the upper part of the rear portion 1 of the bolt, and a spring-loaded plunger 27, Fig. 12, mounted in a hole 31 in the rear part 1 engages a slot 29 in the cam 17 to retain the safety catch in the firing position.

Drum 7 is rotatably carried by frames 5, 6, Fig. 7, and is indexed by a wheel 42 driven by means 41. A ring 30 has a groove 31 filled with Novoplast or like pressure medium, a piston 26 engages the groove and pistons 29 co-operate with the Novoplast to move the drum against a flange 38, thus clamping the drum. Chucking devices 8 are operated by a rotary valve 35 which can be moved from the position of Fig. 8, to the position of Fig. 10, by a piston 67. A frame 83 of work-inserting device 15, Figs. 16- 20, is movably mounted on piston-rods 78 secured to frames 5, 6, and a bracket 79. Abutments 92 are carried by brackets 79, and two pairs of jaws 80, Fig. 19, and a work-holding basket 86, are secured to frame 83. In operation, the chucking devices in positions 21-23, Fig. 4, hold workpieces, and drilling and screwing heads 9-14 operate on the work. When the operations are completed the heads are retracted, a signal is transmitted to driving device 41, and drum 7 is indexed to bring newly inserted workpieces from position 21 to position 22, and to unload workpieces from position 24. Valve 35 is simultaneously actuated to open devices 8 in position 24 to release the workpieces on to conveyer 76, which conveys them to pallets 20. Pistons 29 lock drum 7, and the operations by the heads are restarted. Frame 83 is moved towards the drum, and into the position of Fig. 17, where workpieces held in jaws 80 are introduced into the open chucking devices in position 21. Valve 35 is actuated to clamp the workpieces at position 21, frame 83 is retracted, and stops 92 move the next workpieces into the jaws of device 15.

Title: Improvements relating to display indicators
Inventor: DOWN EDMUND GERRARD
IPC: G08B5/32
Filed: 1961-07-05
Abstract: 968,104. Electric selective signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 4,1962 [July 5,1961], No. 24304/61. Heading G4H. In a display indicator comprising an endless belt having characters thereon, a rotary switching device for controlling the position to which the belt is to be driven is coupled to a drive wheel which moves the belt. An electromagnet causes the drive wheel to be stepped, which thereby steps the rotary device. In the embodiment described A.C. is applied to certain ones of six contacts, chosen in accordance with the binary code, which feed corresponding binary coded discs in an assembly 19. When the belt is not in the position set up on the contacts current flows in coil 9 and armature 10 oscillates, thereby stepping drive wheel 2 by ratchet and pawl means. The belt is threaded over a number of wheels to reduce its apparent length, and characters are viewed through a window 5. As the drive wheel steps round, projections 18, which engage the belt, co-operate with pallets 22, 23 thereby causing member 20 to be oscillated about point 21 once for each change in character at the window. Pawl 24 moves with the member and steps assembly 19, the ratchet on this assembly having 36 teeth, the same as the number of characters on the belt. Thus, for a complete revolution of the belt, assembly 19, which includes the code discs, rotates once. When the code discs have been moved to a position corresponding to that set up on the six contacts, the A.C. circuit is broken and stepping ceases. Specification 721,683 is referred to.
