Title: Polyimide foams
IPC: C08J9/00
Filed: 1979-02-01
Abstract: A known process produces a polyimide foam from a mixture of aromatic diamines and partial esters of a benzophenonetetracarboxylic acid. In this process the precursors are converted into polyimide foams by the application of heat. In this invention the polyimide foam is then further heated while compressed at 3 to 20 p.s.i.g., yielding a dense, rigid and structurally strong, intumescent material. If the duration of such further treatment is less than 3 minutes a rigid foam of uniform density results; if it is over 10 minutes a composite structure with a low density core and hard high density skin results.

Title: Apparatus for positioning a slide member
IPC: H03J5/10
Filed: 1979-05-18
Abstract: Apparatus for selecting the position of a slide member 85, which may be connected to a variable tuning inductance 80 in a radio receiver, comprises a plurality of individually adjustable position setting elements 47, mounted around a rotatable turret 45. The turret is rotated to bring a selected element into a location where it is resiliently engaged by a contact 87'' carried by the slide member 85. The contact and slide member are movable toward and away from the elements 47, and the position of the slide member is determined by the engagement of the contact with the selected element. The contact 87'' is also resiliently displaceable transversely to prevent obstruction of the movement of the elements. A first operating knob 25 can be depressed to rotate the turret in a step-wise manner, and also rotated to adjust the elements.A second knob 23 allows rapid rotation of the turret in either direction to a desired position. <IMAGE>

Patent GB-2036465-A (GB)
Title: Electrical Connector Housing
IPC: H01R13/42
Filed: 1979-10-08
Abstract: A dielectric body with a passageway for accommodating an electrical contact receptacle 14 has: (1) a forward stop 30 to limit forward movement of the contact; (2) abutment shoulders 48 spaced from the forward stop to limit rearward movement of the contact; and (3) a flexible latching means 50 which initially moves out of the way as a contact is inserted into the passageway but then engages a rear edge of the engagement section 16 of the contact when the contact reaches its fully inserted position. The flexible latching means 50 is designed to avoid interference with the termination section 18 of the contact and to bias the engagement section 16 of the contact against the bottom 44 of the passageway. The forward stop, the abutment shoulders and the flexible latch cooperate to lock the contact in the housing, the latch means 50 preferably being bifurcated to engage behind respective spring rolls 26 of the contact receptacle 14. <IMAGE>

Title: Heating apparatus for a glass house
IPC: A01G9/24
Filed: 1981-05-15
Abstract: Heating apparatus for a glass house 3 includes a heat pump 11 through which is circulated air from the glass house 3, via ducts 12 and 13. The heat pump 11 extracts energy from the air circulated through it, and transfers the energy to liquid in a liquid reservoir 8. When it is desired subsequently to heat the glass house 3, air therefrom is no longer circulated through the heat pump 11, and the relatively hot liquid from the reservoir 8 is circulated through a pipe network 2. A boiler 1 supplies any additional heat to the liquid in the pipe network 2, but its output requirements are relatively reduced. Whilst the glass house 3 is being heated, the heat pump 11 may continue to extract heat from atmospheric air, instead of from air from the glass house 3. <IMAGE>

Title: Well completion apparatus
IPC: E21B34/14
Filed: 1981-07-17
Abstract: A tubing string 16 extends downhole in a cased borehole to a jet perforating gun 18. A packer device 12 is located uphole of a releasable coupling apparatus 21.The coupling apparatus 21 has an annular piston therein which is moved to release the lower string. Two spaced apart movable annular pistons are series connected in the tubing string at a location below the packer 12 and above the gun 18. Flow ports 30, 42, formed in the tubing wall, are covered by the pistons. A ball of appropriate diameter can be circulated downhole and seated upon either of the pistons, thereby forcing a selected piston in a downhole direction. Circulation ports 28 are provided below the lower piston in proximity of a gun firing head. The lower piston includes a shaft depending axially therefrom and into proximity of a detonator of the gun firing head, so that when the lower piston is forced downhole, the shaft contacts the firing head which detonates the shaped charges of the perforating gun. This assembly of elements enables many different options to be exercised prior to firing the gun. <IMAGE>

Title: Metallurgical lance
Inventor: EASTWOOD OWEN
IPC: C22B9/05
Filed: 1982-03-24
Abstract: Normally metallurgical lances are formed by a hey metal tube encased in a refractory sieve and because of their relatively long length such lances flex in use thereby propagating cracks in the refractory and encouraging the growth of cracks that are otherwise formed during shock loading of the lance as it enters the bath of metal and because of the differential expansion that occurs between the refractory and the tube. This invention provides a lance of high rigidity and reduced tendancy to cracking and spalling. The lance has a tubular member 2 for the passage of gas or a mixture of gases and solids encased in a sleeve 3 of an appropriate refractory material, there being secured to and spaced around the periphery of the tubular member a number of secondary tubular members 6. The members 6 may be used for the passage of coolant. <IMAGE>

Title: File reinforcements
IPC: B29C51/42
Filed: 1982-05-28
Abstract: A file reinforcement used to reinforce the edges of a hole in a document is formed of self adhesive vinyl plastics sheet material. The inner edge 12, which is aligned with the hole in the document, and the outer edge 11, which defines the periphery of the reinforcement, are both formed with an increased thickness compared to the remainder of the reinforcement. The increased thickness edges of the reinforcement are formed by the application of heat and high frequency welding radiation. This increased thickness provides added resistance to tearing where it is needed most. There is also disclosed a file reinforcement which is polygonal rather than the conventional circular shape, and the preferred shape is square. <IMAGE>
