Title: Equipment for producing an nmr image as a planar projection
Inventor: SHITTENHELM RUDOLF
IPC: G01R33/54
Filed: 1981-11-12
Abstract: In a system for imaging a subject 2 by means of nuclear magnetic resonance, and including means 3 for the application of magnetic fields to the subject and for detecting excursions of atomic nuclei of the subject from their state of equilibrium by a high-frequency magnetic excitation pulse, means 13, 17 control the image production so that the image produced represents a projection of at least part of the subject on to a prescribed plane 1. In this way complete pictures, corresponding to X-ray shadow images, are produced with the aid of nuclear magnetic resonance. As described, a magnetic field gradient defines a slice of the subject for projection, successive slices being selected by moving the subject or varying the frequency of the excitation pulse to build up the projection a line at a time. <IMAGE>

Title: Process for the preparation of sintered bodies
Inventor: ISHIKAWA TOSHIKATSU
IPC: C04B35/63
Filed: 1983-01-18
Abstract: A process for preparing a sintered body comprises forming a body by either impregnating a porous shaped member such as a strand of carbon fibers with an organosilicon high molecular weight compound or by moulding a mixture of a filler material such as silicon carbide powder with such an organosilicon compound.

Title: Portable light
Inventor: ROWLSON RAYMOND PATRICK
IPC: F21L4/06
Filed: 1983-10-21
Abstract: Existing battery powered portable lighting systems seek to maximise the length of time the light is available by using low powered bulbs or large batteries. There are many applications where a brighter light is required, but for shorter durations and this can be achieved by using lightweight rechargeable batteries 5 combined with higher powered bulbs 10, 11 to provide a lightweight system which can be conveniently recharged between use. The system can be formed for use as a cycle lamp or a hand-held torch, providing better visibility and leading to greater safety. The bulb, or bulbs, 10, 11 can be rigidly or removably attached to a battery holder 4 or coupled to the holder via wires 9 and a connector 1. The connector 1 can also be used for coupling a charger to the batteries 5. <IMAGE>

Patent GB-2146719-A (GB)
Title: Improvements in dual circuit brake valves
Inventor: MCCANN DENIS JOHN
IPC: B60T15/04
Filed: 1984-08-16
Abstract: In a dual-circuit brake valve assembly having primary and secondary pistons (9, 10) for controlling operation of co-axial primary and secondary double valves for respective circuits valves (11, 12) the secondary piston (10) is modified to provide exhaust valve seatings (26, 25) for both valves which are relatively movable axially through a limited distance. The seatings are urged by a spring (29) relatively away from each other normally into an extended position, but the seatings (26, 25) are movable against the spring (29) and into abutment with each other to define a rigid sub-assembly in a retracted position. The amount of relative movement between the extended and retracted positions is chosen to correspond substantially to the degree by which the secondary piston (10) may move during initial stages of vehicle cab oscillations, thereby substantially preventing fluid from being exhausted from the brakes unintentionally. <IMAGE>

Title: Anti side tone arrangements
Inventor: MALLOY CHRISTOPHER
IPC: H04M1/58
Filed: 1985-12-13
Abstract: A telephone circuit which is suitable for use with a reactive telephone line includes a line matching impedance 21 having a complex value. This would make it very difficult to achieve satisfactory side tone suppression, but the side tone suppression circuit 5, 6, 10-15 is directly coupled to the complex impedance matching circuit by way of resistor 25. In this way the side tone suppression is largely independent of component errors in the impedance matching circuit. <IMAGE>

Patent GB-2181204-A (GB)
Title: Screw retention means
Inventor: SHUTE GRAHAM
IPC: F16B41/00
Filed: 1986-08-26
Abstract: A sheet of material 1 to be secured to a support has through it an aperture 2 with three slots 3 extending outwardly from it. The aperture 2 has a diameter which will allow passage through it of the shaft 4 of a screw but which will prevent passage of the screw head 5. End faces 3A of each slot 3 continue upwardly from the sheet 1 in a stem 6 which terminates at its upper end in a head 7. The head 7 has an inwardly-inclined upper face 8 and downwardly-facing shoulder 9 which extends over the slot 3. The stem is resilient. In use, the screw is pressed downwards into the aperture 2 so that the screw head 5 engages the inclined upper face 8 of the head 7 so forcing the head 7 radially outwardly by bending the stem 6, to allow the head of the screw to pass. When it has done so, the resilient stem 6 returns to its original position, bringing the head 7 over the screw so that the screw is captive in the aperture 2. <IMAGE>
