Title: Generating electricity
Inventor: LAWSON-TANCRED SIR HENRY
IPC: F02B3/06
Filed: 1983-06-14
Abstract: Electricity is generated from a random power source such as a wind wheel 12 driving a generator 11 through an intermediate energy form such as a hydraulic arrangement 14, 15, 16. A controllable power source such as a diesel engine 13 can also drive the generator through the same intermediate arrangement to make up power when demand exceeds the supply from the random source. Other random power sources may be solar power or tidal or wave power. The controllable power source may instead comprise a wood or peat burning engine for raising steam. <IMAGE>

Patent GB-2136703-A (GB)
Title: Apparatus for supplying a mixture of gases
Inventor: FRANKENBERGER HORST
IPC: B01F23/10
Filed: 1984-03-01
Abstract: The apparatus comprises supply lines (4,6) brought together to form a mixed gas line (7). Adjustable valves (1, 9) are connected by way of a gear unit (13) in such a way that they are opened or closed in the same direction when actuated, the gear ratio of the spur gears (15, 17) determining the mixture ratio of the gases. When used to supply an anaesthetic to a patient, the gases may be N2O and O2. The O2 valve (9) may be by-passed by an O2 line (11) which comprises a valve (12), and by opening this valve, the O2 content in the respiratory gas can be increased, the minimum proportion of O2 in the mixture still, however, being determined by the gear ratio. Thus a minimum concentration of oxygen in the respiratory gas is always obtained and above the minimum concentration the mixture ratio can be independently adjusted. <IMAGE>

Title: An automatic bundle-tying tool
Inventor: O'SULLIVAN DENIS P
IPC: B29C65/08
Filed: 1984-03-28
Abstract: An automatic bundle-tying tool has a compact housing with a pair of curved pincer-shaped jaws, one of which pivots outward to accommodate a bundle of wires or similar elongated objects, and then pivots inward to abut the other, fixed jaw. Plastic tying tape drawn from a storage spool is fed around the tape guide groove formed on the internal surface of each of the mating jaws, encircling the bundle. A pair of thin tapered anvils clamp the overlapped tape against the tip of an ultrasonic welding transducer, and a reverse feed mechanism draws the tape tight around the bundle while slack tape is re-wound on the storage spool by a resilient spring biased spool hub. After ultrasonic welding, automatic spring-driven linkages unclamp and withdraw the anvils, sever the tied bundle from the tape supply and open the movable jaw to release the tied bundle. A preferred embodiment is lightweight, portable and easy to operate.

Patent GB-2305044-A (GB)
Title: Radar receiver
Inventor: INGRAM STUART JOHN
IPC: G01S7/41
Filed: 1984-05-21
Abstract: A radar arrangement is described which is capable of recognising different types of target (e.g. classes of helicopters) which each produce a characteristic frequency-time variation in the reflected radar signal. The received radar signal is time-compressed and multiple replicas are produced each of which, after frequency conversion in a mixer (29), is mixed with a particular one of a set of predetermined frequency sweep signals produced by a controllable chirp generator (34). The predetermined frequency sweeps produced by the chirp generator each have a form such that, when mixed with a processed reflected signal from a particular one of the target types to be recognised, the result is the production of a composite frequency sweep which is the mirror image of the frequency/time characteristic of a signal processing unit (35) to which the output of the mixer is fed. When a match is made the output from the signal processing unit (38) is a pulse.
Patent GB-2160445-A (GB)

Filed: 1984-06-21
Abstract: In an apparatus for the separation of solid particles from hydrous slurries having particles of different settling velocities, such as slurries containing minerals including ore solids, coal and sands, the slurry solids are subjected to the jetting action of water discharged through openings in a perforated barrier plate mounted in a tauls to effect separation between particles of greater settling velocity, which progress downwardly through the openings and are discharged in an underflow, and particles of lower velocity that progress upwardly and are discharged in an overflow.
Patent GB-2171904-A (GB)
Title: Explosion suppression arrangement
Inventor: BALL DAVID NICHOLAS
IPC: A62C3/00
Filed: 1985-03-06
Abstract: Rods of propellant explosive are mounted parallel to each other to form a cased explosive charges, the casing 6 being substantially impervious. A hollow cutter assembly 20 carrying cutter blades 22 and 24 is normally held in the position illustrated. In the event of risk of explosion of the explosive charge 5, a diaphragm 34 is ruptured by an electrically detonatable explosive actuator 40. Explosion suppressant 32, stored under pressure in a container 18, advances rapidly through the ruptured diaphragm 34 and through the cutter assembly 20 and forces the latter rapidly downwards so that the blades 22 and 24 pierce the end of the impervious casing 6. The explosion suppressant can thus rapidly enter within the explosive charge 5. If the latter is in the form of individual rods of explosive arranged parallel to each other with their axial ends facing the cutter blades 22, 24, the dispersion process is aided by the air spaces between the rods. <IMAGE>
Patent GB-2157852-A (GB)
Title: The compensation of instabilities in charged-particle beams
Inventor: SMITH KENNETH CHARLES ARTHUR
IPC: H01J37/26
Filed: 1985-04-15
Abstract: Instability in the beam 10 of an electron microscope or other high- resolution instrument arises from externally induced periodic noise and lateral drift. The effect of the instability is measured directly in terms of the focal quality of the image while compensating waveforms are superimposed on the instrument supplies and varied to restore the optimum focal quality. Focal quality at a screen 14 is continuously assessed by means of camera 20 and unit 21 which measure the variance of brightness in a succession of images. In response to the value of variance, a programmed computer 23 instructs a power supply unit 24 to produce waveforms of mains and harmonic frequencies and of EHT oscillator frequency, and to follow an iterative routine of steps in magnitude and phase until a desired value of variance is observed. <IMAGE>

The compressed air expands in the barrel (10) to eject the capsule. <IMAGE>
Patent GB-2170071-A (GB)
Title: Waveform synthesiser
Inventor: VOORE TAIVO
IPC: G06G7/28
Filed: 1985-09-12
Abstract: A waveform synthesiser for generating a television picture display comprises a plurality of difference amplifiers (A2, A3, A4) which are connected in sequence with the input of an integrator (A8). The difference amplifiers (A2, A3, A4) are supplied with a number of input voltages defining waveform parameters which cause the output of the integrator to rise and fall according to the difference between successive difference amplifier outputs. The time each difference amplifier is connected with the integrator is adjusted by means of variable delay flip-flop triggers (M1, M2, M3, M4) which actuate switches (S1, S2, S3) on the difference amplifier outputs. These delays are ganged to vary in inverse proportion to the variable gain of amplifiers (A5, A6, A7) also located on the output of the difference amplifiers. A first waveform defining voltage level (RV1) is applied to the output of the integrator to set an initial value of the waveform. To suppress glitches during transfer from one difference amplifier to another a low-pass filter is connected with the output of the integrator before the synthesiser is matched to the remaining television circuitry. Each waveform parameter is thus independent and does not require iterative adjustment when synthesising a wave. <IMAGE>
Patent GB-2166542-A (GB)
Title: Air conditioning systems for aircraft cabins
Inventor: SIMMONDS NORMAN HUGH
IPC: B64D13/06
Filed: 1985-11-04
Abstract: Pressurised air from the aircraft engine compressor is supplied via a duct 10 and a heat exchange 13, to an expansion turbine 14 which drives a fan 16 which assists the flow of ram air from an intake 24 through the heat exchanger. The cooled, pressurised air is fed to the cabin 19 via a water extractor 18 and demist ducts 20 and ventilation ducts 21. Air leaves the cabin via a valve 30. A selector valve 25 normally is set so that all the coolant air for the heat exchanger is drawn from the ambient air duct 24. When, however, the pressure or volume of the cooled, pressurised air is insufficient, the selector valve is set so that air is drawn from the cabin through a duct 28, thereby increasing circulation of air through the cabin. In a third position of the valve 25, only ram air is supplied to the cabin. <IMAGE>
Patent GB-2182973-A (GB)
Title: Casement fastener
Inventor: DOUGLAS JACK ERNEST
IPC: E05B13/10
Filed: 1985-11-13
Abstract: A casement fastener comprising a handle 1 pivotally mounted on a base plate 2 and a security locking device to secure the handle 1 in the fastened position. The locking device includes a barrel 8 mounted for limited rotation in the handle 1 by a key 14 received in a key-way 13 and an upstanding pillar 7 on the base plate 2. The pillar 7 is received within the barrel 8 on pivotting the handle 1 to the fastened position with the barrel 8 in the unlocked position whereupon the barrel 8 is rotatable to the locked position to retain the pillar 7 within the barrel 8 to secure the handle 1 in the fastened position. The key 14 is removable from the key-way 13 in the locked position and, to prevent rotation of the barrel 8 to the unlocked position with the key 14 removed, the barrel 8 has a recess 17 opening into the key-way 13 in which a detent 19 resiliently biassed towards the barrel 8 automatically locates on removing the key 14 to retain the barrel 8 in the locked position. The detent 19 is disengaged from the recess 17 to permit rotation of the barrel 8 to the unlocked position on insertion of the key 14 in the key-way 13. <IMAGE>
Patent GB-853686-A (GB)
Abstract: 853,686. Photogrammetry. NETHERLANDS, MINISTER OF TRANSPORT & WATER CONTROL. March 8, 1957 [March 8, 1956], No. 7774/57. Class 97(1) Photogrammetric plotting apparatus uses computing linkages of rods arranged in a plane. Fig. 2 shows a linkage which may be used in apparatus for evaluating photographs taken during level flight. A member h represents the centre of the photograph i.e. the image of the nadir point and the rods n1, n2, n3, n4 are set, to define a square, at distances from h equal to the focal length of the objective. Two rods sl, s2 are interconnected by bevel gearing to be rotatable equally and oppositely about the member h and having sliding pivotal connections with the rods n1, n2 respectively, which connections support a rod s5. Oppositely rotatable rods s6, s8 have similar connections with the rods n3, n4 and s9. Further the rods s1, s6 have connections at A, B with rods A1, B1 movable parallel to themselves and to the rods n1, n3. In operation, the rod system is moved so that the intersection p of the rods s5, s9 corresponds to a particular point on the photograph. It is shown that the rod A1 moves to a point representing the required x co-ordinate on the map and B1 to a point representing the y co-ordinate. The relationship of both to h is determined by the z co-ordinate. The modified system of Fig. 4 takes account of the inclination of the camera axis. The rods s1, s6 are replaced by rods s10, s12 which provide the connection with the rods s5, s9, together with other rods s3, s7 rotatable with the rods s10, s12 but offset therefrom by amounts depending on the said inclination. The rods s3, s7 determine the pivot points A, B. Also, the rods nl, n2, while still parallel, are no longer set perpendicular to the parallel rods n3, n4, the obliquity also depending on the inclination of the camera axis. In apparatus employing these linkages the point p is not traced directly over the photograph but is connected to one end of a link moved parallel to itself by a parallelogram linkage, the other end forming the tracing member. Two complete linkages are formed and optical systems employing reflectors enable the observer's two eyes to see the two tracing points. Fig. 5 'shows the interconnection of the two linkages. The reference numerals Fig. 5 correspond to those of Fig. 4 with the addition of L and R to designate the parts of the systems used for the left and right photographs. The x co-ordinate is adjusted by a handwheel 5 which, through shafting 6, 7 simultaneously adjusts the pivots BL, -BR of the rods S7L, S7R along the rod B1 by means of screw threads. The y co-ordinate is adjusted by the handwheel 19 acting through shafting 20, 21, 22 to adjust the pivots AL, AR of the rods S3L, S3R along the rods A1L, AIR. The z co-ordinate is adjusted by the pedal wheel 8 acting through shafting 9, 10, 11, 12, 14 to operate screw threads 17, 18, 13, 29, 15, 16 to produce transverse movements of the rods B1, A1L, A1R.
