Title: Improvements in and relating to the stitching of materials
Inventor: MARGERESON GREGORY JOHN
IPC: D05B39/00
Filed: 1969-07-09
Abstract: 1282893 Sewing machines W J CLARKSON Ltd 7 July 1970 [9 July 1969] 34624/69 Addition to 1207834 Heading DIG In the apparatus for stitching around a shaped piece of material by means of a guide slot 30 in a work plate 1 according to Parent Specification the pin fixed to the machine frame and located in the guide slot 30 is replaced by a movable stylus finger 31 mounted in a spherical bearing 40 so that the stylus finger can be deflected in any direction from a vertical position to control the hydraulic rams which move the work plate 1 in two directions at right angles and within the plane of the work plate. As shown in Figs. 4 and 5 the mounting for the stylus is bolted to the machine frame with the stylus pointing upwards into the guide slot 30 and first and second valves 44, 45 are provided each of which controls a ram for moving the work plate along a respective one of its two directions the two valves having operating members 46, 57 perpendicular to one another which are operable by deflection of the stylus finger from the vertical position if such deflection has a component of movement along the axis of the respective operating member. A spring loaded plunger 67 presses against the lower portion of the stylus so that it is deflected from the vertical position so that it is inclined in the slot 30. When the slot engages the stylus finger, due to a change in direction of the slot, to move it into a given vertical plane. This operates either valve 44 or 45 depending on the direction of movement and the fluid pressure supply is removed from the appropriate ram thus preventing any shock from being transmitted against the stylus finger. As soon as the stylus reaches the vertical position the appropriate microswitch will be closed. This causes operation of a hydraulic motor 70 and rotates a secondary housing 61, and spring plunger 67, until the stylus is again leaning forward and the microswitch is released thus allowing fluid flow to the other ram to provide a movement of the work plate in the new direction of the guide. A secondary guide slot is also provided, the arrangement being that the needle of the sewing machine passes through an axial hole in that follower.

Abstract: 1,186,296. Knotting-apparatus. DITTA MESDAN DI PETRO MESSA. 23 July, 1968 [5 Aug., 1967], No. 35009/68. Heading D1C. The length of the loose ends of the two threads secured together by a fisherman's knot can be varied by restricting the movement of the usual tensioning arm 1 which passes between the knot-tying bills of the knotting apparatus. This is achieved by a pivoted lever having a pin and slot connection with a slide plate which engages the end 9 of a lever 4 coupled to a cam following arm 6 such that the latter can be moved into and out of the path of a cam 7. The arm 1 is attached to the arm 6 such that its movement is transmitted to the lever 1. Consequently adjustment of the lever 3 varies the position of the arm 6 and the exent to which the arm 1 is moved such that its movement in connection with the threads can be varied to alter the extent of the threads which are left as loose ends.

Title: Improvements in or relating to electromagnetic relays
Inventor: LENEY ERIC NORMAN
IPC: H01H50/56
Filed: 1953-12-17
Abstract: 770.030. Electromagnetic relays. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Sept. 22, 1954 [Dec. 17, 1953], No. 35126/53. Class 38(5) A relay comprises two groups of contact springs placed one above the other, each group comprising a number of (e.g. six) fixed blade (or wire), contacts 22 moulded in an insulating block 26. The block 26 is located in recesses formed in upper and lower blocks 27, 28 supporting sets of movable wire contact springs 23, 24 biased towards opposite sides of the blades 22. As shown, each blade 22 cooperates on each side with a pair of contacts 23 or 24 to form change-over contacts, but simple make or break contacts may be provided. The pile-up comprising the blocks 26, 27, 28 is held within a U- shaped clamp 35, welded to the magnet yoke 11, by a tapered corrugated spring 32 so as to exert a force which is resisted by the yoke and the top of the clamp. The blades 22,of each group are moulded near their free ends in an insulating block 29, having in each end a hole freely receiving a screw 36, the blocks engaging nuts on the screws under the downward bias of the blocks whereby the bolt heads are held against the yoke 11 and the position of the blades may be altered by adjusting the nuts. Slots an upper and lower ribs 30, 31 on the blocks 29 guide the springs 23, 24. The armature 13 controls a frame 39 supported and biased downwardly by limbs 37, 38 ,of a U-shaped spring 33 mounted in the contact pileup. Four insulating rods 40, 41 extending across the frame operate, respectively, the four sets of springs 23, 24, the rods 41 holding the contacts 24 open when the relay is not energized and the frame 39 being raised on energization of the coil 10 so that rods 40 open the contacts 23. A sequential operation of the contacts may be obtained by giving the rods 40. 41 parts of different diameters (Figs. 6, 7, not shown). In two modified arrangements of mounting the contact pile-up (Figs. 3-5, not shown) an upstanding arm is welded on each side of the yoke 11 at the sides of the pile-up and the tops of the arms are joined by a U-shaped clip which is placed over the top of the pileup, tongues on the clip locking with cutout portions in the arms. In one modification the clamping pressure is provided by a downwardly-bowed portion formed in the bight of the clip, and in the other modification by a screw threaded into a plate positioned beneath the bight and engaging the top of the pile-up.

Title: Improvements in or relating to a shell fuze
IPC: F42C9/14
Filed: 1956-11-19
Abstract: 811,397. Projectile fuzes. JUNGHANS, A. G., Geb. Nov. 19, 1956 [Nov. 18, 1955; Oct. 18, 1956], No. 35295/56. Addition to 788,628. Class 9(1) Direct action projectile fuze having clockwork controlled self-destruction device, the movement regulator of the clockwork and one or more of the train of gears between the drive and the regulator being directly mounted on the firing pin 13 as in the parent Specification has the safety latch of the percussion pin controlled by a lever adapted to be released by centrifugal force, the lever being held at safe for a predetermined period by an element operatively connected to the clockwork movement. The latch 39 has a depending arm 39b engaging a pin 38 carried by a lever 100 pivoted on a pin 101 mounted in the plate 32. As the fuze rotates a torque is produced tending to move the lever counter-clockwise so that the pin 38 moves outwards from the arm 39b, but the lever arm 100b is immobilized by a weight 102 riveted to a rack 104 which meshes with pinion 23 and is guided by tracks in the plates 32, 35. The length of the abutment surface 102a corresponds to the predetermined safety path during which the lever 100 cannot turn. The guide tracks for the rack can be inspected from the periphery of the fuze to check the setting. Plates 105, 106, 107 housing the primer 14 and safety means for the detonator 15 are held in position by a nut 109 and provided with flash passages which are blocked by a slide valve 110 during acceleration of the shell. When acceleration ceases, centrifugal force moves the valve aside. Gas passages 11d extend upwardly from the primer chamber to vent the primer gases, should it be accidentally ignited while the valve 110 is in the safety position. A thin metal or plastic disc 111 may cover the passages 11d After firing the shell an element (not shown) releases the regulator and frees the clockwork mechanism thus liberating the rack 104, which then moves outwardly and when the rack is out of mesh with the pinion, the lever swings suddenly to release the latch of the firing pin. In a modification, Fig. 7, the slide valve 110 is replaced by a rotary valve 210 pivoted on latch arbor 211. The arbor 211 has a collar cut away to form an abutment for the lever 100 to prevent rotation of the latch arbor (and hence of valve 210) while the lever engages the weight 102. In this case the firing pin and flash pass ages are freed simultaneously.
Patent GB-353292-A (GB)
Abstract: 353,292. Zeroizing-mechanism. SQUIRE, F. E., 52, Chancery Lane, London. -(Monroe Calculating Machine Co. ; 555, Mitchell Street, Orange, New Jersey, U.S.A.) Aug. 25, 1930, No. 25368. [Class 106 (i).] The resetting stops in the resetting mechanism of a calculating machine register can be set individually to an active or to an inactive position. A bar 407 is rocked in one direction or the other on pivots 87, 88 by cams on the shafts 86, 84 which carry respectively the totalizer 13 and the rotation counter 85. The rocking of this bar causes stops 89 or 93 to be interposed in the path of projections 90 on the numeral wheels so that when the shaft 86 or the shaft 84 is rotated by mechanism described in Specifications 157,841 and 157,844, [both in Class 106 (i), Calculating &c.], the corresponding wheels are reset to zero. According to the present invention, certain of the stops are formed as members 92 pivoted to the bar 407 and rotated into active or inactive positions by finger levers 103. The stops are retained in their two positions by spring catches 101. When a stop is set to its inactive position the setting on the corresponding numeral wheel is retained during a zeroizing operation. In a modification, Fig. 5, the stop 91 has three positions, a normal one in which it arrests the numeral wheel at its zero position by means of a projection 90, an intermediate position in which it arrests the wheel at a setting of " 5 " by means of a member 38, and an inactive position. In a second modification, Fig. 3, the stops 108 are integral with sliders 107 slidable along the bar 407. To each slider is pivoted a finger lever 112 having a lug 113 engaging a recess 114 in the bar 407. Movement of a lever 112 to the right thus moves the slider 107 and stop 108 to the right to its inactive position and also pushes all the other sliders and stops on its right-hand side to their inactive positions.

Filed: 1970-07-22
Abstract: 1,255,908. Swaging machines. G.F.M. GES FUR FERTIGUNGSTECHNIK UND MASCHINENBAU A.G. 22 July, 1970 [28 July, 1969], No. 35424/70. Heading B3H. A gripping head for a swaging machine comprises a set of jaws mounted on a rotatable spindle which is driven by a rotary hydraulic motor 4 whose hydraulic supply is controlled by a slide valve 6 which directs the fluid to opposite sides of the motor in alternation. The movement of the slide valve is controlled by a solenoid operated pilot valve 8 actuated by signals from a pulse generator operated by a drive-shaft to one of the machine hammers. The fluid is supplied from a pump through a check valve 15 and line 14 with an accumulator 17 and returned along a line 16 to an accumulator 19 or to a tank through a relief valve 18. Bypass lines 20, 20a extend from the supply line 14 to the return line 16 through check valves. The valve spool 7 blocks both the lines 14, 16 in its intermediate position. The motor is driven through a line 12 when the spool is in its righthand position and through a line 12a when the spool is in the left-hand position. At the changeover the fluid can flow between the accumulators to absorb the kinetic energy of the motor. The reversal of the motor is arranged to occur just prior to a hammer blow to stop the workpiece rotation and prevent twisting of the workpiece. The gripping head spindle (2), Fig. 1 (not shown), has a disc (23) with spaced cams (24) to operate a limit switch (25). The switch operates a sliding spool solenoid - operated valve 26 which can connect the supply lines 12, 12a to the motor directly to the supply and return lines 14, 16. For swaging rectangular or polygonal cross-section workpieces the spool valve 6 and the pilot valve 8 are retained in their intermediate position and the rotation of the spindle is controlled by the valve 26.

Title: Improvements in flyweight rotational speed governors
Inventor: WHITEHEAD JOHN PARKIN
IPC: G05D13/08
Filed: 1956-11-21
Abstract: 813,939. Governors. DOWTY FUEL SYSTEMS Ltd. Feb. 19, 1958 [Nov. 21, 1956], No. 35673/56. Class 57. A centrifugal governor for operation completely immersed in fluid comprises one or more main flyweights 18, 19 and one or more lower-density auxiliary flyweights 21, 22 mounted for rotation with the governor so that the effect of centrifugal force produces a control force in the main flyweights and an opposing force in the auxiliary flyweights the size and disposition of the flyweights being such that the effect of fluid centrifugal forces on the control and opposing forces is substantially balanced. As applied to a fuel supply system for a gas turbine, the main flyweights 18, 19, of brass, are mounted on the upper ends of levers 5, 6 and the auxiliary flyweights 21, 22, of aluminium, on the lower end. The levers 5, 6 are pivotally mounted on spindles 7, 8 carried by a support member 4 adapted to be rotated by a turbine-driven shaft 33 within a casing 1 and are provided with extensions 9, 11 which through a ball 12, recess 13 and pin 14, act, upon the lower end of a rod 17. The flyweights 18, 19 and 21, 22 may be of the same shape and disposed at similar distances from the pivots 7, 8 but they may have different sizes and/or spacings. Also the lighter weights 21, 22 may be hollow and not necessarily of a homogeneous material. In operation, due to the centrifugal force acting upon the heavier weights 18, 19 the upper ends of thel evers 5, 6 move outwardly thereby acting through the extension 9, 11 to lift the rod 17 which in turn moves a fuel-control beam 23. As the space surrounding the governor within the casing 1 is filled with fuel, the latter also develops a centrifugal force but since it acts upon both ends of the levers 5, 6 its effect is substantially balanced. The flyweights are loaded by a spring 24 which acts upon the upper end of the rod 17 and is preset by a knob 29. The spring pressure may also be varied through a manually-operated rack and pinion 26, 27.
