Title: Ultrasonic imaging device
Inventor: VAN LIEUBEN DE ZIELUE KOSSUTH
IPC: A61B8/00
Filed: 1981-08-03
Abstract: Simplicity of design and ease of focussing and manipulation are the main inventive features of a small lightweight hand-held portable instrument called The Ultrasonic Photoscope which, when passed over the surface of the skin, produces, instantly, live pictures of a pulsating heart and other organs and tissues inside the human body in clear well defined detail on a T.V. monitor while being simultaneously video recorded for re-examination. Tilting the instrument to and fro provides a stereoscopic picture of the shape and location of a tumour or lesion. One control provides pinpoint focus. Enhanced by an infrared ray for added contrast, the instrument directs a variable ultrasonic microwave to the desired focal depth from where it is reflected and picked up bye piezoelectric crystal transducer and amplified and processed electronically to provide instant pictures. The equipment is transistorised, frequency modulated and battery powered for universal use. <IMAGE>

Title: Voltage detector circuits
IPC: H03K17/30
Filed: 1981-09-04
Abstract: A method of and apparatus for monitoring first and second voltages in an electric circuit is suitable for use in earth leakage protection devices. A capacitor is charged from the first of the voltages (being the larger) through a first resistor and is discharged through an impedance across which the second voltage is applied and a resistor in series with it. Oscillations are generated in a circuit comprising an oscillating four- layer device, such as a programmable unijunction transistor, and a bias voltage applied to the anode-gate of the programmable unijunction transistor is related to the voltage existing across the capacitor. Oscillations are supressed below and above lower and upper cut-off points on the bias voltage characteristic of the programmable unijunction transistor, and an appropriate monitor, such as a switching diode, responds to the disappearance or abrupt reduction in amplitude of the oscillations. <IMAGE>

Patent GB-2091884-A (GB)
Title: Investigation of samples by N.M.R. techniques
IPC: G01R33/54
Filed: 1982-01-25
Abstract: Spatially discriminated information is obtained by appropriate processing of data derived from a series of pulsed N.M.R. operations performed during application of a magnetic field exhibiting a linear gradient whose magnitude is different for each operation. In obtaining a two-dimensional (shadow) image of spin density distribution as viewed along the z-axis, coil sets (5 and 6) are used to generate magnetic field components giving x and y gradients, the former being changed stepwise in magnitude and the latter being fixed. For each value of x gradient, the sample (1) is irradiated with pulsed r.f. energy, resultant N.M.R. signals being detected by phase-sensitive detectors (19 and 20) whose outputs are regularly sampled by A-D converters (25 and 26). Processing of the complete sampled data by a computer (12) involves both Fourier transformation with respect to x gradient magnitude and Fourier transformation with respect to time. For sectional images a third coil set (7) is used to generate a component giving an alternating z gradient and the irradiation consists of a train of pulses. <IMAGE>

Title: Method for making rim elastomers using a catalyst system containing a polymeric component
IPC: C08G18/16
Filed: 1982-03-17
Abstract: Polymers containing tertiary amine groups, and substantially free from active hydrogen atoms, are useful catalysts for the production of reaction injection moulded (RIM) polyurethanes. These catalysts do not interfere with the curing of paints on a moulded article or interfere in the urethane network. They are advantageously employed as a solution or dispersion in one of the polyurethane- forming components. Advantageous catalysts are polymers made from monomers of the formula   <IMAGE>  wherein Y = -O- or -NH-,  R1= H or CH3,  R2-R7 independently = H, CH3, or alkyl,  m = 0-1,  n = 0-6, and R8 and R9 independently = CH3, or alkyl, or together with the nitrogen atom to which they are attached form a N-containing heterocyclic group. The catalyst composition may additionally comprise a fast gelation organotin catalyst, e.g. dibutyltin dilaurate, and a delayed action organotin catalyst, e.g. an alkyltin mercaptide. The catalyst composition may be prepared by polymerizing the tertiary amine-containing monomer in a liquid which is a polyurethane forming component, e.g. the polyol, chain-extender or crosslinker.
Patent GB-2119067-A (GB)
Title: Control apparatus
Inventor: KELLET GILLIAN DENISE
IPC: G05G1/04
Filed: 1982-04-17
Abstract: A requirement can often arise for data to be entered into an apparatus by means of a manually operable control device, such as a hand lever able to move in two perpendicular directions. This may cause fatigue in an operator after a relatively short period of time.   The likelihood of fatigue can be reduced by providing an arm support structure as shown in Figure 2. A member 4, which is covered with a layer of resilient padding 5, provides support for the operator's forearm. The member 4 is attached to a block 7 surrounding and locating a bush 8 which is slidably mounted on a shaft 9. Thus the member 4 is movable in one of the directions required to operate the hand lever. Two helical springs 14 and 15 serve to hold the member 4 in a rest position. <IMAGE>

Patent GB-821416-A (GB)
Abstract: 821,416. Gyroscopic apparatus. FRANCAIS ETAT. Feb. 20, 1956 [Feb. 21, 1955], No. 5181/56. Class 97(3) In a three ring suspension for a gyrovertical, the outer ring may be locked either to the support or to the next ring, the lock being changed from one condition to the other when the gyro spin axis makes a given angle with one of the axes of rotation of the ring. As shown in Fig. 1, the gyro-vertical 1 is supported in the usual gimbal rings 2, 3, which in turn are supported in a ring 4 mounted in fixed bearings. Normally, a roller 8 is forced into engagement with a depression in a heartshaped cam 9 fixed to the ring 4 which is thereby locked. The shaft of ring 2 carries an arm 5 which moves over two conducting studs 6, 6a mounted on the ring 3. When the spin axis of the gyro approaches the axis of rotation of the ring 3, which would result in the loss of one degree of freedom, the arm 5 engages one of the studs 6, 6a and completes the circuit to the motor 7, which drives a pinion 41, Fig. 5, forming part of a sleeve 42 threadably engaged with a spindle 43 carrying the roller 8. A prolongation 44 of the spindle of the roller 8 engages a slot in the ring 4, so that rotation of the sleeve 42 causes the roller 8 to be retracted from the cam 9. At the same time, sleeve 42 is geared through bevelled pinions 46, 47 to a sleeve 48, which engages a threaded spindle 49 carrying a roller 11, a prolongation 50 of the spindle of which engages another slot in the ring 4. Thus, as the roller 8 is removed from engagement with the cam 9, the roller 11 is forced into engagement with a second heart-shaped cam 12 connected to the ring 3, so that the ring 3 is now locked to the ring 4, which has just been freed. The suspension system may also be applied to the combination of a gyro-vertical and directional gyroscope described in Specification 777,698. In a second form of the apparatus, Fig. 8, an arm 62 is pivoted to a lug 63 formed on the ring 4. The roller 8 is carried by a spindle 60 mounted on the arm 62, and is normally in engagement with the cam 9 as shown. When the spin axis of the gyro approaches the axis of rotation of the gimbal ring 3, the arm is rotated withdrawing roller 8 from the cam 9 and being a roller 11 mounted on a spindle 61 on the arm 62, into engagement with the cam 12. Specification 639,192 also is referred to.

Patent GB-2139975-A (GB)
Title: Railway systems with tight curves
Inventor: PRIOR ALAN JOHN
IPC: B61F5/38
Filed: 1983-05-16
Abstract: The aim is for a train to turn as tight as an articulated lorry. This is achieved by widening the tyre of the wheels, the additional tyre width being more tapered than the conventional part of the tyre. For example, a wheel for 4ft 8<1>/2in (1.435m) gauge is 12in (305mm) wide; this width comprises a flange of 1in (25mm), a tread portion of 2.75 DEG  taper which is 4in (102mm) wide and a tread portion of 20 DEG  taper which is 7in (178mm) wide. The tight radius curved track is of accelerated geometry and the gauge widens (e.g. to 5ft 2in (1.575m)) as the curve tightens to maintain the track/wheels circumference ratios. The axles are pivoted in the bogies to maintain the wheels at right angles to the radius of the curve by a link from the axle to the mainframe of the rolling stock and a diagonal link to the other axle in the same bogie. With the mainframe/axle link fixed to one side of the inside axle and fixed to the mainframe on the same side but to an appropriate distance outside and the other side of the bogie pivot, a progressive pivoting of the axles is achieved, corresponding to the curve and maintaining the wheels at right angles to the radius of the curve at all times. <IMAGE>
