Title: Improvements in or relating to Welding
Inventor: ADDIE JAMES WILLIAM
IPC: B23K20/12
Filed: 1966-10-14
Abstract: 1,151,414. Welding by fusion; friction welding. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 11 Oct., 1967 [14 Oct., 1966], No. 46135/66. Heading B3R. Two parts 1, 5 are welded together by friction welding an annular ferrule to one of the parts, e.g. 1, to form a spigot thereon and by welding the other part, e.g. 5, to the ferrule by friction welding or non-consumable electrode arc welding (Fig. 2, not shown). If the other part is friction welded the composition of the ferrule is standard and may be the same as that of either part, but if the other part is welded by non- consumable electrode arc welding the ferrule has a non-standard composition, e.g. up to 0À15% carbon, up to 0À02% sulphur and not less than 1À0% manganese. In a modification (Fig. 3, not shown), two ferrules may be used. The two parts to be welded may be a tube and tube-plate of a heat exchanger.

Title: A loading or digging device
IPC: E02F3/18
Filed: 1961-12-27
Abstract: 950,781. Earth-digging machines. C. DOYER. Dec. 27, 1961, No. 46309/61. Heading E1F. In a digging machine is a driven, rotating shaft to which is pivotally secured one or more scoops from which material is ejected when the or each bucket comes into contact with an abutment that abruptly retards the movement imparted to the bucket by the shaft, the bucket on clearing the abutment being returned to a normal positional relationship to the shaft by springs. A coil spring 15 is mounted about the pivot pin 16 connecting the arms 6 of the scoop 7 to lugs 5 on the driven shaft 3. Cam wheels 19 on the arms 6 engage with cam surfaces 19, 20, 21, 22, 23 in plates secured in the frame of the machine parallel to the arms 6. As shown in traversing the cam tracks between the surfaces 20, 21 thereof the cam wheels 19 cause the arms to be swung back against the spring 15 so that when the wheels 19 clear the cam track at 2, the scoop is impelled into the material to be dug by the spring. Similar tensioning of the spring occurs over the surface 22 of the cam track so that on the wheels 19 clearing the part 22 of the track the scoop is impelled forwards and rearwards until the wheels 19 hit the abutment portion 23 of the cam track to cause expulsion of the contents of the scoop.

Title: Apparatus for simulating the effects of aerodynamic forces on aircraft controls
IPC: B64C13/46
Filed: 1971-10-06
Abstract: 1411942 Artificial feel LUCAS INDUSTRIES Ltd 5 Jan 1973 [6 Oct 1971] 46567/71 Heading B7G Apparatus for providing, on a manually operated part 63 of a power-driven control 71 of an aircraft, a simulated effect of aerodynamic forces on the aircraft control surfaces, comprises a pair of means for generating respective fluid pressures P 1 , P 2 , each dependent on the pitot and static air pressures on the aircraft, pistons 66 and 67, Fig. 3, between which the pressure P 1  is applied, an abutment 68 on one piston engageable with the other, an output member 69 coacting with the piston 66, a further piston 76 urged towards the piston 67 by the pressure P 2 , a passage 80 whereby a pressure P 3  is applied to the sides of the pistons 66, 67 remote from the pressure P 1 , a passage 82 whereby a pressure P 4  is applied to the. sides of the piston 76 remote from pressure P 2 , and a member 74 coacting with the pistons 67, 76 so that movement of the piston 67 in response to the pressure difference (P 1 -P 3 ) is opposed by movement of the piston 76 in response to the pressure difference (P 2 -P 4 ). Thus the output on the member 69 represents the pressure difference (P 1 -P 3 ) across the piston 66, unless the pressure P, fails, when it will represent the presure difference (P 2 -P 4 ) across the piston 76. The member 69 is connected to a bell crank 61, whose motion is opposed by centring springs (83), (84), Fig. 2 (not shown), spring (91) and damper (93), and which is connected to the manual control 63. The pressure P 3  is from a low pressure return line 46 and the pressure P 1 , between the pressure P 3  and that of a source 47, is determined by a valve 34, Fig. 1, adjustable by a lever 17 responsive to the movement of a diaphragm 14 between chambers 11, 12 at pitot and static pressures respectively. Such movement of the lever 17 is opposed, with greater leverage, by movement of a diaphragm 15, between chamber 13, at pitot pressure, and chamber 12, but only when the Mach number is such that the effect of pitot pressure overcomes the effect on diaphragm 15 of evacuated capsule 26. The connection between the lever 17 and the valve 34 includes a roller 30 whose position is adjusted by a cam 33 positioned in accordance with the sweep of the (variable geometry) wings of the aircraft. Similar equipment determines the pressures P 2 , P 4 .

Filed: 1970-10-01
Abstract: 1331759 Automatic speed control  MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 1 Oct 1970 [7 Oct 1969 14 Nov 1969] 46830/70 Heading G3R Two heads are displaced by a fixed distance and are associated with a magnetic recording medium such as a tape, disc or cylinder, one of the heads recording a reference signal of predetermined frequency on the medium while the other head reproduces the recorded signal. The reproduced signal is phase-compared with the reference signal and the medium is driven in accordance with the error signal whereby a fixed relationship is maintained between the speed of the medium and the frequency of the reference signal. In addition, a detector produces a signal representing the rotational phase of the driving mechanism for comparison with a reference signal of fixed frequency whereby the medium is also driven in accordance with the result of this comparison. As shown, a D.C. motor 2' is driven by a phase comparator 12' and a speed control circuit 14' whereby a signal from head 26 associated with a head disc 21 is synchronized with a signal at terminal 9 which is equivalent to a half cycle of the vertical componenet in a video signal to be recorded. A brushless D. C. capstan motor 2 is controlled by a phase comparator 12, adder 13, and drive circuit 14 whereby signals from rotational position detector 19 and the signal from terminal 9 are  synchronized. At the same time, the output from reproducing head 8 is phase-compared with the signal from terminal 9 in the unit 18 and the resulting signal is applied to the adder 13. The signal from the terminal 9 is applied to the recording head 7 which provides phase compensation as well as recording a control signal. During playback, the terminal 9 is connected to an oscillator which generates a reference signal, and the motor 2' is controlled as during the recording mode. The capstan motor 2 is controlled by the units 12, 13, 14, the unit 12 comparing the output of the head 8 with a signal from head 26. In another arrangement, a signal is recorded on the tape by a third head, this signal being used to control the capstan speed during playback. This third head is located ahead of the heads 7, 8, in the direction of tape feed to erase the signals recorded by the head 7, Fig. 5 (not shown).

Abstract: 1,168,267. Rotary pumps and motors. ABEX CORP. Oct.25, 1966 [Feb.16, 1966], No.47912/66. Heading F1F. A rotary sliding vane pump or motor of the multiple abutment type, as described in Specification 1, 165, 207, having beneath each vane 18, plunger 41 slidable in a bore 38, and having an axial bore 42 and coned ends, with the outer coned end 43 forming with the plane inner end of the vane a check valve, includes in the sleeve 40, Fig. 3 and 4 closing the annular groove 57 in the rotor 14, blind bores 58 defining pressure chambers connected by flow restricting passages 46 with the bores 38 within which the plungers 41 slide. As pump or motor speed increases, centrifugal force urging the vanes outwardly also increases but since at higher speeds each vane passes through the suction zones more often per unit of time, the flow through passages 46 is greater per unit of time and hence the pressure drop is greater at higher speeds and establishes a relatively lower pressure acting on the inner end of each plunger 47. Thus the increased centrifugal force urging the vanes outwardly is mitigated by a reduction in the fluid-pressure force to reduce wear and damage.

Abstract: 1,059,910. Air guns. DAISY MANUFACTURING CO. Nov. 15, 1965 [Dec. 16, 1964], No. 48447/65. Heading F3C. An air gun comprises a plunger assembly 32 acted on by a compression spring 47 and cocked by means of a cocking lever 53 and pinion 64 assembly which is movable forwardly by the forward movement of a forearm 17 and rack 67 assembly such that a lug 55 of the lever 53 engages a forward face 59 of a clip 61 secured to the plunger assembly 32. The lug 55 and clip 61 are biased to wards each other by a tension spring 71 acting on the lever 53. Rearward movement of the forearm 17 and hence of the cocking lever 53 helped by tension spring 71, moves the plunger assembly 32 against the spring 47. A sear 77 is normally pivoted upwardly by a torsion spring 89, but in the rearward movement of the plunger assembly 32 it is engaged by the clip 61, the sear being then urged downwardly into holding contact with the cocking lever 53. On actuation of the trigger 97, a lower surface 99 of the trigger lever 79 depresses the cocking lever 53 to disengage the lug 55 and the clip 61, thus releasing the plunger assembly 32 and causing compressed air to urge a projectile from a feed cylinder 29 through the barrel 21. In its upward movement, the sear 77 engages a portion of the trigger lever 79 to urge the trigger forwardly until a projection of the trigger abuts a surface 105 of the receiver 11.
