Title: Improvements relating to the flash welding of cast iron
IPC: B23K11/16
Filed: 1952-06-25
Abstract: 727,675. Welding by pressure. RORVERKEN I. GOTEBORG AKTIEBOLAG. June 25, 1952 [June 25, 1951], No. 15967/52. Class 83 (4). Each oast iron piece of a flash-welded article has a carbon content of 2.7-3.6 per cent with the content of one piece not varying from the content of the other piece by more than 0.5 per cent and with silicon and phosphorus contents not exceeding 1.9 and 0.5 per cent respectively, the phosphorus content of one piece not varying from the content of the other piece by more than 0.2 per cent. The pieces preferably have a structure with finely divided graphite or with more bound carbon than free graphite. The two cast iron pieces A are clamped in copper jaws E connected across the low voltage, e.g. 7-15 volts, secondary of a transformer T. If the melting temperature of one piece is higher than that of the other, the distance a for that piece may be reduced. A power of 0.6 KVA per mm.<SP>2</SP> of welding area is employed for tubular pieces and 0.05 KVA per mm.<SP>2</SP> for solid pieces for areas between 5000- 18000 mm.<SP>2</SP> An upset pressure of 3-9 kg. per mm.<SP>2</SP> of welding area is used and welding is quickly effected to heat only a narrow zone. After welding the pieces may be rapidly cooled to 400-500‹ C. by water cooling the jaws and then allowed to cool in room atmosphere. Cast iron pipes with a flange at one end may be welded to produce a pipe flanged at each end.

Title: An improved method of balancing telephone cables
IPC: H04B3/34
Filed: 1927-06-16
Abstract: 302,373. Pirelli-General Cable Works, Ltd., and Werren, H. T. June 16, 1927. Induction. preventing and minimizing. - A method of balancing a section of telephone or telegraph cable consists in measuring. the capacity unbalances of each of the cable lengths which constitute the section, and determining the crossings between the conductors of each two-pair core or quad at each successive joint to produce the minimum residual unbalance, the connections being such that similar cores are joined together throughout the section, for example, the colour scheme of the cores is preserved or a core has the same neighbours in each length. Groups of lengths may be balanced by the method and appropriate crossings between the groups subsequently determined. The crossings at some joints may be determined to minimize only the withinquad unbalance and at others, only the betweenquad unbalances, or, at some joints to minimize both these unbalances and at others, either of them. Auxiliary balancing condensers may be used. Some of the layers of cores in a cable may be balanced by known methods, and used for twowire working, and others by the present method used for four-wire working. A particular method described consists in determining the crossings required in a quad, hereinafter referred to as No. 1, to minimize the residual within-quad unbalances. The crossings in the next quad No. 2 are then determined to minimize both its withinquad unbalances and also the unbalances between quads No. 1 and No. 2. Quad No. 3 is now dealt with by taking into consideration its within quadunbalances and the unbalance between it and adjacent quads, the remaining quads being similarly treated.

Abstract: 918,630. Locking rods. OAK MFG. CO. May 11, 1960, No. 16606/60. Class 80 (3). [Also in Group XXXVII] In switch or other mechanism wherein parallel push rods such as 21, 22 may be depressed against respective springs 28, each depressed rod being locked " in " by a respective tooth 35 on a common latch bar 34 extending through the push rods, whereby the depression of one rod releases any previously - depressed rod, there is provided an additional push rod 23, depression of which shifts the latch bar to release any previously - depressed rod, the rod 23 then remaining in an " in " position, and further depression of which, to an " innermost " position, releases the rod 23 itself, and allows it to return to its " out " position. The rod 23 shifts the latch bar 34 by means of a finger 65 engaging a dog 54 mounted for limited pivotal movement on the bar, the dog allowing free outward movement of the rod 23. A rocker arm 42, Fig. 4, mounted by an L-shaped slot 43 on a pin 41 on the rod 23 and loaded by a spring 47, has a shoulder 68 which on depression of rod 23 engages the underside 70 of the bar 34. As pressure on rod 23 is released it rises within the limits of slot 43, and the arm 42 is positioned by the spring 47 and a fixed cam plate 51. The rod 23 is now locked in its " in " position. Further depression of rod 23 causes surface 50a on arm 42 to engage the top of the bar 34, thereby rocking the arm 42 counterclockwise. As pressure on the rod 23 is released the cam plate 51 maintains the shoulder 68 clear of the bar 34 and allows rod 23 to return to its " out " position. The rod 23 can also be returned by depression of a rod 21 or 22, which shifts the bar 34 to present a recess 69 to the shoulder 68, thereby disengaging the arm 42 from the bar 34. Each push rod has fingers 30, 31 holding an insulating strip 19 (Fig. 1) carrying switch contacts coacting with fixed contacts on an insulating strip 17.

The front portion A of the case slides over the back portion B and is detachably secured to it by pins a entering bayonet slots b. Other forms of detachable fastenings may, however, be used. The dial may be secured to the front portion A by a screw and two studs. or the front portion itself may constitute the dial. The outer part C of the bezel consists of a metal ring which has, integral with it, a hinge (not shown) at one side and a catch at the other for securing it to the casing A. The inner part of the bezel comprises a ring D having slots in its flange through which pin c<2> fixed to the outer bezel may pass. When the glass E is in position, the inner bezel D is applied so that the pins pass through the slots, the said inner bezel then being rotated a little to lock the whole. The back portion B of the casing has two openings b<1>, b<2>, which may be closed by the partial rotation of a liner F by means of an exterior knob f<2>. The liner has openings f, f<1>, and is in the form of a split ring forced by spring action against the casing. The liner may work on ball bearings having packings to exclude dust. The liner may also consist of one piece of sufficient length to cover at one time both openings, one end being provided with a knob sliding in a slot in the case and having a quickacting screw for securing the liner in its closed position. The other end of the liner may have a spring which, as the liner is rotated to close the openings, comes into contact with a loop in the case and forces the liner and case into close contact. The liner in its closed position may, by means of catches, automatically lock the bezel and also the front part of the case to the rear. The clock movement (not shown) may be attached to the front of the casing by pillars connected to the front movement plate (the pillars may also extend through to the back plate) or, according to the Provisional Specification, portions of the front cover A may be pressed to form brackets to which the clock movement is attached.

Abstract: 1,155,913. Pipe couplings. AUTOMOTIVE PRODUCTS CO. Ltd. 22 March, 1968 [12 April, 1967], No. 16720/67. Heading F2G. A number of levers 16 are arranged in spaced relationship around a tubular body 1 and a sleeve 10 is movable by actuating means such as a rotatable bush 11 in screw-threaded engagement with the sleeve lengthwise of the body, such movement of the sleeve resulting in corresponding movement of the levers combined with a swinging movement thereof. Movement of the sleeve in one direction causes the levers to engage the flange 26 of a pipe or hose 27 to clamp the flange against a mating surface of the body and movement of the sleeve in the opposite direction causes the levers to move out of clamping engagement with the flange. As shown, the levers 16, which are pivoted on the sleeve, are biased inwardly by springs 22 and as the sleeve is moved by rotation of the bush 11 to the unclamping position, are urged outwardly by engagement of the cranked parts 19 of the levers with the cam surface 9. In the clamping position shown, the levers keep the flange 26 in engagement with one of a number of counterbores provided to accommodate flanges of different diameters. Fluid tightness of the coupling is maintained by an annular sealing member 28 carried on a ring 29 urged by a spring 30 and by pressure fluid towards the flange 26, and by sealing members 31, 32. In a modification, the pivotal mounting of each lever incorporates a spherical seating.
