Patent GB-707520-A (GB)
Title: Radio modulators comprising variable reactors in aerial feed circuits
IPC: H01Q5/00
Filed: 1952-10-10
Abstract: 707,520. Modulating apparatus. STANDARD TELEPHONES & CABLES, Ltd. Oct. 10, 1952 [Nov. 10, 1951], No. 25438/52. Class 40 (5) A radio modulator, particularly for glide-path or localizer beacons, comprises a two-conductor carrier transmission line 27 28, Fig. 1A, connecting a source 1 to a load 29, with a reactance 30 of one sign in one conductor 27, means for producing a high impedance 32 in the other conductor 28, and means for periodically shunting said high impedance by a second reactance 31 of opposite sign to that in the conductor 27. When coaxial lines are used, a portion of the line is of U-shape, and the inductive reactance 30 is produced in the inner conductor by removing the outer conductor at the bend, while the high impedance in the outer conductor is produced by shorting the two branches of the outer conductor at a point distant about <SP>#</SP> 4  from their open ends. In Fig. 1, the system is shown applied to a glide-path beacon in which signals modulated at different tones are radiated by aerials 10, 11 energized from a common carrier source 1 through a bridge divider 3 and coaxial lines 9, 11. The line 9 is bent back on itself at 14 and the outer conductor is removed at the U bend to expose a portion 18 of the inner conductor of such length as to operate as an inductive reactance. The leg portions 16, 17 of the U have their outer conductors connected by a variable capacity 21 at their free ends, and by a shorting bar 20 a quarter wave-length from those ends. The quarter-wave pair thus formed provides high impedance in the outer conductor, and this is shunted by the variable reactance afforded by the capacity 21. As this capacity passes through a value which resonates with the inductance 18, maximum carrier current flows to the aerial 10. The variable capacity may comprise stationary electrodes attached to the respective outers 16, 17, and a multi-bladed electrode rotating in a plane half-way between them. The rotary electrode may be driven by a motor M which may also drive a second rotary electrode 26 with a different number of blades associated with the coaxial line 11 supplying the second aerial 12. A variable network 13 may control the relative amplitude of the radiated waves modulated by the respective tones produced by the blades. An example of the structural form of one of the modulators is given in Fig. 2 (not shown).

Class 57 In speed controlling apparatus, a centrifugal governor comprises weights 15 guided on rods 13 and loaded by springs 14, the movement of the weights being transmitted to the plunger 20 by bell cranks 18 and pins 21. A bush 25 is threaded on the plunger 20 and is locked by a pin 23 and a sleeve 30 is normally centrally located on an enlargement 26 of the bush and retained in position by two compressed springs 35, 37. The sleeve 30 transmits movements of the governor to the control rack 50 of a fuel-injection pump by a lever 40 the fulcrum 44 of which is carried by a manually adjustable lever 45. Idling and maximum fuel stops 51, 52 respectively limit the movement of the rack 50 but if engaged the manual lever 45 can be moved further whereby the sleeve 30 moves relatively to the bush 25 and one of the springs 35, 37 is further compressed with a consequent variation of the engine speed. In an alternative arrangement the sleeve 30 is centred on the bush 25 by a single spring. The fulcrum 44 may be guided in a curved track during manual adjustment and the maximum fuel stop may be spring loaded. Specification 463,325 is referred to.

Filed: 1956-08-22
Abstract: 848,706. Coating with metals. YARDNEY INTERNATIONAL CORPORATION. Aug. 22, 1956 [Aug. 22, 1955], No. 25709/56. Class 82(2) [Also in Group XXXVI] A porous electrode body for a primary or secondary electric cell or battery is made by depositing peripherally molten particles upon a collecting surface in at least two superposed layers of different densities and incorporating one end of a terminal lead in the body. The particles may be deposited by flame spraying or by being passed through a high-frequency field, the density of the layers being determined by particle size, the temperature to which the particles are subjected and the length of time for which they are in the heating zone. Terminal leads may be provided on the collecting surface before deposition of the layers. Alternatively, as shown in Fig. 2, leads 29 may be dropped into the body during its formation, low density layers 34a, 34c being deposited from spray guns 5a, 5c and high density layer 34b being deposited from spray gun 5b. Continuously moving belt 27 acts as the collecting surface and stripper blade 31 removes the completed electrode body 34. If desired, the body may be impregnated with graphite by spraying with a dispersion of graphite in water. The collecting surface, which may alternatively be in the form of a flat plate or a cylinder, may be left in contact with the body to act as a supporting structure. Alternatively, the collecting surface may be of e.g. cardboard, paper, textile or plastic, and removed from the body by burning. Suitable electrode materials are silver, zinc, cadmium, nickel, copper, iron and iron alloys.

Title: Applicator for mounting pins on circuit boards
IPC: H05K13/04
Filed: 1970-05-28
Abstract: 1283468 Mounting contacts in terminal boards; jointing by stamping; shearing BERG ELECTRONICS Inc 28 May 1970 [25 Aug 1969] 25736/70 Headings B3A B3Q and B3W A method of mounting a contact pin 186 on a circuit board 18 comprises positioning the contact in approximate alignment with a pickup punch 54, accurately aligning the contact relative to the punch, moving the punchaxially to-seat one end of the contact in a hole 56 in the punch, and then moving the punch and contact to pass the other end of-the contact through a circuit board hole 270 where it is secured. A circuit board support (26) is moved until the required hole 270 is aligned with the punch 54 and anvil 124, Fig. 1 (not shown). An air cylinder 42 moves the punch downwardly and a cylinder (130) simultaneouslyraises the anvil into contact with the underside of the board 18. Before the punch is level with the leading pin 186 of a strip of pins, cams 50, 52 co-operate with rollers 86, 88 to pivot arms 78, 80 thereby driving slides 72, 74 towards each other. A ferrule 188 on the pin is then clamped between shoulders 190, 192 and the pin is accurately aligned with the hole 270. The end 64 of the pin enters a hole 50 in the punch and a spring 60 holds it therein as the slide 74 is withdrawn when the roller 86 moves along the surface 266 of the cam-50. Cutting edges on the punch 54 and slide 72 sever the ferrule 188 from a carrier strip. Immediately thereafter the roller 88 moves along a surface 268 on the cam 52 to withdraw the slide 72. As the rollers move off the cams, the arms 78, 80 are held against stops 116, 118 by springs 112, 114 and the slides are fully retracted. The punch 54 now drives the lower end of the pin through the hole 270 into a recess in the anvil and as the air cylinder 42 approaches the end of its stroke, the ferrule 188 is deformed in the hole to secure the pin therein. The leading pin is fed to the cut-off position between the slides by a reciprocating finger (154), Fig. 5 (not shown), on the downward stroke of the punch and the finger is retracted on the upward stroke, the strip of contact pins being prevented from retraction by a spring-loaded finger (172).

Title: Improvements in and relating to the production of articles having plastic memory
IPC: B29C48/10
Filed: 1961-07-17
Abstract: 990,235. Heat shrinkable hollow articles. RAYCHEM CORPORATION. July 17, 1961 [July 15, 1960 No. 25900/61. Heading B5B. Dimensionally heat-unstable hollow article s having a predetermined linear dimension ar e made by heating an article made from (1) a cross-linked crystalline polymeric material o r from (2) a crystalline polymeric material that exhibits elastomeric properties at a temperatur e equal to or above the upper limit of its crystalline melting-point, to a temperature at least equal to the upper limit of the crystalline melting - point of the material, applying a pressure differential between the inside and the outside of the article while it is at such temperature, and cooling the article to a temperature below the crystalline melting-point while continuing to apply a pressure differential in the same sense as the aforementioned pressure differential between the inside and outside of the article to effect a change in the linear dimension of the article such that it assumes the predetermined linear dimension. The hollow article may be e.g. tubing, caps or splice closures. The pressure differential which is established while tubing is heated to at least its crystalline melting point may be insufficient to change or expand the tube to its final predetermined diameter at that temperature, but sufficient to effect the change or expansion upon cooling the tube below the crystalline melting-point while maintaining that pressure differential. Specified polymeric materials of type (1) are polyolefins e.g. polyethylene, polypropylene; polyvinyls e.g. polyvinyl chloride, polyvinyl acetate, or polyamides, which have been cross-linked chemically or by irradiation. Specified polymers of type (2) are polytetrafluoroethylene, and high molecular weight polyethylene and polypropylene. In apparatus for producing heat-shrinkable polyethylene tubing (Fig. 1) irradiated polyethylene tubing 21, pressurized by connection to air supply 50 is fed from reel 20, in pressure vessel 11, into a heat liquid bath 27 contained in pressure vessel 12. The heated tubing is then led through aperture 30 (Fig. 2) and cooled by ring 35, through which cooling liquid circulates, and by sprays 39. Due to the cooling and the higher internal pressure, the tubing expands to contact surface 36 of ring 35. The expansion is controlled by the pressure differential and not by the internal diameter of ring 35. The expanded tubing 2 la is removed by driven roller 45. When the expanded tubing is re-heated to above the crystalline melting point, the diameter and wall thickness return to their original values.

Filed: 1934-09-10
Abstract: 431,981. Spray carburetters. MONOT, P., 10, Rue de la Livatte, and SIRIEZ, R., 13, Rue Burdeau, both in Roanne, Loire, France. Sept. 10, 1934, No. 25985. Convention date, Sept. 8, 1933. [Class 7 (iii)] The supply and atomization of the fuel are controlled principally by an auxiliary pressure applied to the liquid fuel directly or a gas exerting a mechanical action thereon, and to a less extent by engine suction acting in a Venturi tube, the action of the auxiliary pressure being controlled by the throttle. As shown, the supply of fuel, fed under pressure to a tank 9, past a valve 11 to the nozzle 16 is controlled by a diaphragm 12 connected to the valve 11 and operated by a cam 14 on the spindle of the throttle valve. In other forms, an air supply controlled by a valve linked to the throttle is blown across, or issues from a nozzle concentric with, the fuel nozzle. Instead of air under pressure, a combustible gas may be used. The Specification as open to inspection under Sect. 91 states that the pressure gas may be tapped from the cylinders, for example by means of a channelled ring screwed on to the sparking-plug which is apertured to afford communication with the ring. This subject-matter does not appear in the Specification as accepted.
