Title: Electrical switching device
Inventor: CONNELL RICHARD ANTHONY
IPC: H01H50/32
Filed: 1988-12-19
Abstract: A switching device for selectively connecting a load to a supply for example via one or other of two meters to enable advantage to be taken of a low tariff rates includes two independently operable electromagnetic relays 20, 22. An interlock (83) to prevent simultaneous closure of two sets of switching contacts (32), (46), and (33), (50) of the relays and an isolating mechanism for moving one (46, 50) of each of the two pairs of contacts further away from its opposed contact (32, 33) in an isolating mode to ensure complete safety for working on equipment downstream from the switching device when the isolating mechanism has been operated. Further switch contacts (80), (82) are provided, also separated by movement of the isolating mechanism, to enable a common neutral supply line also to be broken. A snap action spring mechanism (56) is provided to transmit drive to the isolating mechanism from a manually operable slider (58) to ensure fast operation and to hold the isolating mechanism in one or other of its two positions. The interlock (83) acts indirectly on the relay armatures (28, 29) through spring fingers (84) and (86) which are separate from the spring arms (30, 31) carrying the switching contact (32) and (33) to facilitate setting up and adjustment of the device. <IMAGE>
Patent GB-883995-A (GB)
Abstract: 883,995. Mechanical switches without quickaction. KOEHLER MANUFACTURING CO. Dec. 10, 1958 [Dec. 12, 1957], No. 39910/58. Class 38 (5). [Also in Group XI] An electric switch mechanism for a miner's lamp is arranged to complete one of a plurality of independently-operable filament circuits within a single bulb. The bulb 18 has a filament 24 connected to two base contacts 28, 30 and a filament 26 connected to base contact 28 and to the base of the bulb. Contact 28 is connected to the battery, the other terminal of which is connected to a rotary switch element comprising two cylinders 36, 38 connected by an eccentric metal pin 40 having an insulated coating 42. The cylinder 38 has two grooves 52 opposite one another in which a V-shaped portion 50a of a brush contact 50 connected to the battery engages. The cylinder 36 has an insulating strip 54 over half the circumference so that a circuit can be completed with either of two contact strips 23, 22 or, in the position shown in Fig. 8, both contact strips can be held out of contact with the cylinder. The contacts 22, 23 are connected to the base contact 30 and the base of the bulb respectively. According to the position of the strip 54 one or other of the filaments can be lighted by rotation of the cylinders by a knurled knob on the outside of the lamp.

Title: Wall using angled shuttering
Inventor: DAVIES GEOFFREY
IPC: E04H4/00
Filed: 1989-04-29
Abstract: A method of constructing the wall of a swimming pool comprises assembling shuttering of inner (3) and outer (4) slab elements spaced essentially parallel and held together by tie bars (6), the shuttering including a layer of elements (12) in which either the inner or outer slabs are set at an angle to the slabs in the layer below so that the separation of the shuttering is changed by the shuttering layer (12). The shuttering is then filled with concrete and a waterproof render is applied to the outside or the inner slabs (3). Using this method the wall can be constructed to support drainage slabs by widening the shuttering at the top of the wall or can alternatively be used to widen the wall where the pool is deep and higher water pressures exist. <IMAGE>

Patent GB-2256970-A (GB)
Title: Forming a mounting hole in a p.c.b
IPC: H05K3/44
Filed: 1991-06-19
Abstract: A countersunk hole in a metallic printed circuit board 1 (eg Fig 1) consisting of a metallic plate 2, an insulating layer (3), and a printed circuit pattern (4), is provided by first forming a rough straight hole 7 consisting of a central main part 7a and radial extensions 8 extending therefrom and then forming a countersunk portion (9) (Figs 3 - 8) around hole 7 by plastic deformation. Since the material of the metallic plate 2 of the metallic p.c.b is allowed to flow into the extensions 8 of hole 7 during plastic deformation, the material of metallic plate 2 in the immediate vicinity of hole 7 is allowed to flow both radially and circumferentially, and the resulting reduction in the difference in the amount of deformation between the metallic plate 2 and the insulating layer (3) prevents peeling of insulating layer (3) from metallic plate 2. Other shapes of the rough hole are detailed (eg Figs 6-8). <IMAGE>

Title: pellet inspection system
Inventor: AHMED HASSAN JUMA
IPC: G01B11/30
Filed: 1992-01-09
Abstract: At least one axially extending linear portion of the peripheral surface of the pellet 74 is optically sensed, a set of digital values representative of the pellet surface is generated, and the set is compared to a predetermined standard. Groups of adjacent locations on the surface of the pellet having values greater or less than the predetermined standard are identified, and the pellet is rejected 58, 60 when a flawed area exceeds a predetermined size. During inspection, the pellet is moved axially through an inspection station 14 by parallel support rolls, 28, 29 spaced by a distance less than the pellet diameter. The rolls 28, 29 are rotated upward and outward from each other, rotating the pellet, and chain dogs 48 are positioned between the spaced rolls for engaging a pellet and moving it along the rolls. The pellet is rejected if its peripheral surface area is too great, and a reference pellet may be used. <IMAGE>

Title: Method for the protection of ferrous pipes with thermoplastics
Inventor: WADDOUPS JOHN BRIAN
IPC: B29C55/24
Filed: 1992-03-31
Abstract: Ferrous pipes are protected by extruding a thermoplastic tube, expanding said tube so as to incorporate potential stress shrinkage therein, sliding the extruded expanded tube over the pipe, and heating the thermoplastic tube to release the potential stress therein, causing the tube to shrink securely about the pipe. Expansion of the extruded thermoplastic tube may be carried out by heating the tube along at least one longitudinal continuous strip or area of its periphery, and stretching the heated strip transverse to its longitudinal direction whereby to expand the tube circumferentially in that strip or by passing the tube through a sizing sleeve with an intermittent movement such that an unexpanded portion of tube is heated within a heating zone of the sizing sleeve and subjected to zero or low internal pressure, then subjected to high pressure so that the heated unexpanded portion of the tube is expanded to fill the sizing sleeve in the heating zone, the pressure in the tube is then reduced causing the tube to shrink away from the internal surface of the sizing sleeve, whereafter the tube is moved forward such that the portion from the heating zone is disposed within a cooling zone of the sizing sleeve and a new portion is disposed in the heating zone and the sequence is repeated.
