Abstract: 1,231,192. Honeycomb structures. ROLLSROYCE (COMPOSITE MATERIALS) Ltd. 9 May, 1968 [11 May, 1967], No. 22001/67. Heading B5N. Plastics units are assembled to form a honeycomb-type structure, which may be curved, by bending them to a skin of plastics, plasticsimpregnated fibres or metal in such an arrangement that opposed parallel bonding surfaces are adjacent and placing jointing members so that opposed parallel surfaces thereof either enter between opposed parallel bonding surfaces of the units or embrace them, adhesive being previously applied to the spaces between the opposed parallel surfaces of the units or the members. A second skin is then bonded on top of the units. Each unit may be box-like with an end wall 12 at one end and with flanges 14 at the other end by which the units may be bonded respectively to the outer skins, and with a pair of webs 16, 18 and a pair of webs 20, 22 which extend further outwardly on each side. When units are pushed laterally together, the webs 16, 18 enter between the webs 20, 22 as shown in Fig. 3, and the stems 41 of members 40 are inserted between the pairs of webs 16, 18, after applying measured quantities of cement to the spaces between the webs. The members 40 are preferably T-shaped with heads 42 which, with the end walls 12, form a substantially continuous surface to receive the second skin. In modifications, the pairs of webs are similarly spaced and dimensioned and butt against one another; or single webs are formed on the units which are embraced by bifurcated stems of the members (the adhesive in this case being applied to the members); or the units each take the form of a pair of walls only with webs arranged as shown in Fig. 9 for co-operation with stems 130 of rectangular section.

Abstract: 1,250,603. Light deflectors. AVIATION SUPPLY, MINISTER OF. 11 Oct., 1968 [18 Oct., 1967], No. 47436/67. Heading H4F. [Also in Divisions G2 and G5] A display device comprises a linear member 1 of transparent material, means 3 for launching a light wave along the member in a trapped mode and means 5 for launching a mechanical pulse along the member in such a way that light escapes from a region of the member which moves with the mechanical pulse along the member. The member may be a rod or a glass or crystal fibre which may be coated with another transparent material. The rod may be bent into a zig-zag pattern and by modulating the light source an image is formed. Alternatively adjacent the member 11 a series of transparent rods 21 to 30 are arranged with a mechanical wave source 19 at one end. Modulated light from source 13 escapes from rod 11 and passes along the rods 21 to 30 from where it escapes in response to pulses from source 19. Pulses from source 15 are delayed by increasing steps with respect to those from source 19 to produce successive line scans. A colour display is achieved using three monochromic sources with independent modulation. The mechanical pulse may be a sound or flexing wave or acoustoelectric effects in semi-conductor crystals may be utilized.

Abstract: 1,252,179. Gas-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. 31 March, 1969 [1 April, 1968], No. 16686/69. Heading H1N. A gas-blast circuit-breaker comprises a main current-breaking "gap" 1 which recloses automatically after opening and a voltage isolating "gap" 2 in series with the gap 1 and which opens when the gap 1 is open and is used to close the circuit through the circuit-breaker. The circuit-breaker is filled with compressed gas and the gap 2 has rounded electrodes 11, 12, a plug contact 13 co-operating with a socket contact 14, an electrodynamic means 19 to initiate the closing movement of the contact 13 and an energy storage device in a high potential situation to supply the means 19. In the arrangement shown, opening of the circuitbreaker is initiated by energizing an electrodynamic means, i.e. a coil 18 to move a piston 36 carrying a moving main contact 7, gas pressure on the piston 36 completing the opening movement. Gas flowing through a channel 37 in the contact 7 opens a valve 39 to vent a cylinder 40 so that gas pressure opens the voltage isolating contact 13. The gas through the channel 37 causes the increase in pressure behind the piston 36 which recloses the main contacts 7, 9 and the valve 39 closes the vent. Reclosing of the circuit-breaker is effected by energizing the coil 19 to initiate the movement of a piston 42 carrying the contact 13. This initial movement moving a valve seat 44 away from a washer 45 so that gas pressure can act on the whole of the piston 42. Each coil 18, 19 is energized when a respective charged capacitor 20, 21 discharges through a photo-thyristor 32, 33, triggered by light through a light guide 34, 35 from lamps 30, 31. Each capacitor is charged by means of a diode 28, 29, a transformer 26, 27 and a generator 24, 25. The generators may be driven by a motor 22 through an insulating shaft 23, by a gas turbine or by an hydraulic motor. Alternatively, the capacitors may be charged from a source, situated at earth potential, through voltage transformers.

Abstract: 1289650 Semi-conductor devices KOGYO GIJUTSUIN 23 April 1970 [18 Sept 1969] 19576/70 Heading H1K The channel region 15a of an IGFET is formed by lateral thermal diffusion of dopant atoms from an ion implanted region. In the device shown the P type channel region 15a is part of a region 15 formed in this way in an N type drain region 12 on an N+ type layer 11. The N type source region 16 is formed by thermal diffusion into the region 15 through the metal mask 14 used to define the initial ionimplanted region which acts as the dopant source for the region 15. Control of the ion energy enables the depth of the part 15b of the region 15 to be controlled independently of the channelwidth of the part 15a. In a modification the dopant for both the region 15 and the region 16 is ion-implanted into the region 12 through the same aperture in the mask 14, and during the subsequent thermal, diffusion process the dopant for the region 15 diffuses faster than that for the region 16, thus providing the necessary channel region 15a.

To move the lift upwardly magnets 9, 10 are simultaneously energized. Slide 11 moves down and so connects chamber 3 and a conduit 12 with a conduit 14 leading to the underside of a piston 16 which unseats valve 20 so that pressure fluid flows to the underside of cylinder 102. The simultaneous upward movement of slider 22 unseats a ball 24 and connects a duct 25 leading from the lower end of cylinder 102 with a duct 27 and a branch duct 30 thereof with an annular recess 36 of control piston 33 and hence with the duct 37 leading to the spring space of valve 5. Near the end of ascent, magnet 10 is de-energized so that conduct 12 is blocked by slider 11 and the motor decelerates and is stopped on de-energizing magnet 9 whereon valve 20 is closed by its spring 21. Fluid-pressure in ducts 27, 30, 37 is exhausted through ducts 55, 17 and the pump pressure in chamber 3 acting through a base 4 in valve 5 lifts the latter and thus connects the pump to return. During descent under gravity and with both magnets 9, 10 energized and the pump inoperative, piston 39 is subjected to the full downward pressure of its spring 41 thereby compressing the spring 34 to displace control piston 33 to a position determined by an adjustable stop 59 thereby regulating the pressure drop between ducts 30, 37. Pressure in duct 37 is opposed by a greater pressure in chamber 3 which unseats piston 5 and connects the underside of motor 102 to exhaust.

Hydraulic circuitry.-The control pressure p v  at 28 may be downstream of a restrictor 48 upstream of which fluid is supplied at a pressure p a  by a pump 49a, 149a, possibly modulated to p m  by units 49b. The control pressure p v  may be applied to an end chamber 61, 161, 281 of a further valve 29, 129, 280 to control further pressures p s , p r  &c. for ratio control and possibly "kick-down" and " idling " signals at 70 and 67 or fluid for lubrication at 73. The control pressure p v  may be inversely proportional to the condition of operation and may be inverted by a valve (80), Fig. 8 (not shown) the inverted pressure being applied to the end chamber 61, 161, 281. The valve (80) is similar to the valve 280, Fig. 12, but has the spring at the other end, and a passage in the spool connecting the chamber 285 via a restrictor with the space between lands 282a and 282b which contains the inverted pressure, p v  being supplied to chamber 285 and the pump supply as in Fig. 12.

The modules may be supported on insulating rods 21 and have their conducting screens 24 connected to a point of mid-potential between input and output potentials for that module and formed by a resistive potential divider connected across one of the capacitor chains (Fig. 4, not shown). Current limiting resistors in series with the output may be located in a metallic tube feeding socket SK2. A shunt circuit comprising a resistor, capacitor and Zener diode is connected in series with the potential divider chain of the lowest potential module so as to provide current monitoring. Inverting.-The voltage multiplying rectifier may be driven by an inverter as shown in Fig. 5 where it is represented by the load RL. Thyristors CSR1, CSR2 are turned on alternately by external pulses, each thyristor being turned off by a resonant commutating circuit L1, CC1 before the next one is triggered. Inductor L2 reduces turn off time of thyristors CSR1, CSR2 due to the application of a limiting commutating voltage by reverse diodes DD1, DD2. This action prevents short-circuiting of the supply E under unfavourable conditions. In Fig. 8 (not shown) the multiplying rectifier is coupled to point Vd via an inductor and a transformer having a tuned primary. In Fig. 10 (not shown) the inductors R1, R2 are replaced by a tapped inductor connected between the two thyristors and having centre tap connected to capacitor CC1 and intermediate tappings connected to the reverse diodes DD1, DD2.
