Abstract: 1,095,457. Selective signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 16, 1966 [Sept. 21, 1965], No. 41424/66. Heading G4H. In a delta-modulation transmission system the inability of the reconstituted signal b, Fig. 3a, to follow a rapid change a when the feedback loop of the encoder. Fig. 1, includes only a simple integrator 11, e.g. as in Specification 970,751 which is referred to, is overcome by feeding an additional signal to the integrator 11 whenever a series of all positive, or all negative pulses, is detected in the output train, Fig. 3b. This is achieved by an integrator 13, a differentiator 14 and a threshold circuit 15 so arranged that a series of pulses of the same polarity causes the output of the differentiator 14 to exceed the upper or lower level of the threshold circuit 15 and results in a signal being applied to the integrator 11. Thus, in effect, the pulses transmitted are not uniformly weighted as in ordinary delta-modulation, but in a series of pulses of the same polarity the weights progressively rise. A modification of the transistor circuit described in Specification 970,751 incorporating the additional feedback is outlined.

Abstract: 1,230,313. Anti-skid braking systems; controlling clutches. AISIN SEIKI CO. Ltd. 22 Oct., 1969 [22 Oct., 1968], No. 51654/69. Headings F2F and F2L. A method for the control of hydraulic brakes for a powered vehicle to avoid lateral skidding of the vehicle, comprises the steps of sensing a wheel lock during a braking of the vehicle wheels, reducing the hydraulic brake pressure upon reception of an instruction signal informing of a sensed wheel lock and, at the same time, releasing the clutch means inserted between the vehicle drive engine and the vehicle wheels upon reception of the signal. As shown, actuation of brake pedal 15 causes pressure oil from the master cylinder 16 to be applied directly to front wheel brakes 17 and, via an anti-skid control 14, to the rear wheel brakes 18. Wheel slip is signalled by a sensor 10 to a computer 11 to close a switch 12 when a change-over valve 13 and the control 14 are actuated in known manner so that oil pressure to the rear wheel brakes 18 is reduced. At the same time as the closure of the switch 12 a relay 19 is operated so that movable contact 21 is engaged with stationary contact 22, a switch 24, upon actuation of the pedal 15, being turned to an "on" position and the solenoid of change-over valve 26 being energized to move the valve 33 to the right as seen in the Figures whereby fluid communication between the pipes 28 and 60 is interrupted and ambient air is admitted through filter 37 and pipe 28 to the chamber 106 of booster 27. With movement of the diaphragm 31 of the booster to the left, the end 38a of plunger 38 is engaged with the recessed end 40a of piston 40 so that the increase in oil pressure in the chamber 41 is conveyed to a clutch releasing cylinder 45 to actuate the clutch release lever 61. In the case of failure of the anti-skid control apparatus, actuation of clutch pedal 62 causes pressurized oil from master cylinder 43 to be conveyed to the space 39b between plunger 38 and piston 40, and through port 49 to the piston 48 which urges the valve seat 54 of diaphragm 47 into engagement with valve 51 to interrupt fluid communication between ports 59 and 60, the valve 50 lifting ftom the seat 54 to bring port 60 into communication with atmospheric air; the pneumatic action is conveyed through valve 26, which has been brought into the position shown in Fig. 1, to the diaphragm 31 which is moved to the left to release the clutch.

Abstract: 1,250,248. Semi-conductor devices. FERRANTI Ltd. 8 June, 1970 [12 June, 1969], No. 29973/69. Heading H1K. Beam leads 18 connected to electrodes 17 on the upper face 12 of a semi-conductor wafer extend laterally beyond the wafer in the plane of the lower face 21 thereof. A passivating layer 13, e.g. of silicon oxide, covers the upper face 12 and extends on the lateral faces 15 as far as the lower face 21, the beam leads 18 lying at least partially on the passivating layer 13. The beam leads 18 are then bonded to conductors, e.g. initially forming parts of a lead frame or situated on an insulating substrate, e.g. of glass. In the latter case the face 21 of the wafer may also be bonded to the substrate by means of an alloyed Au layer thereon, but this additional bond may be omitted. The device, e.g. a transistor, is initially formed in the upper face (12) of a common semi-conductor body (11), Figs. 1-4 (not shown), containing many devices, and is laterally surrounded by a moat (14) etched partly through the body (11) from its upper face (12). The sides (15) and base (16) of the moat (14) are covered with silicon oxide (13), as is the upper face (12). Contacts (17) and beam leads (18) are then provided by sequential deposition of Ti, Pt and Au, the beam leads (18) being thickened by electrodeposited Au. The Ti and Pt layers are preferably removed from the ends (19) of the beam leads (18) remote from the device to facilitate subsequent mounting. This may be achieved by providing a temporary layer of Cu between the Ti and Pt layers at the ends (19), and etching away the Cu in such a way that the contiguous layers of Ti and Pt are also removed. This process may be aided by thinning or removing the oxide (13) at the base (16) of the moat (14), prior to deposition of the beam leads. If it is desired to space the beam leads (18) from the lateral faces of the wafer they are deposited over an easily-removable material provided on the oxide layer (13) on the sides (15) of the moat (14), this material subsequently being removed. After the beam leads (18) have been formed the semi-conductor body (11) is lapped and etched from its lower face (20) until separate wafers are defined, each possessing laterally extending beam lead portions (19). The wafers are then mounted as described above.

[Also in Division C7] A cathode for an electron tube, e.g. an oscilloscope, a television tube or a power tube, is formed by suspending particles of a composition containing at least one alkaline earth metal compound which is heat-decomposable to an oxide in a solution of dicobalt octacarbonyl in an organic solvent, heating the solution until metallic cobalt coats the particles, removing the cobalt-coated particles from the solution and coating them upon a metal substrate. In an example 100 gm. of particles of mixed Ba, Sr and Mg carbonates are suspended in amyl acetate containing 3 gm. of dissolved Co 2 (CO) 8 , and heated in a reflux condenser for 2 hours at 110 C. to form on the particles a cobalt coating which constitutes about 1À0% of the weight of the particles. After cleaning, a cylindrical cup-shaped cathode nickel substrate is coated, e.g. by spraying, with a suspension of the cobalt-coated particles in a binder and a solvent for the binder to a thickness of 3À5 mils. and a coating weight of about 0À35 mgm. In another example the cobalt comprises 3À0 weight per cent of the particles. The cathode substrate consists essentially of nickel with, in weight per cent, 0À0-10À5 W, 0À005-0À3 Mg or Ti and 0À005-0À3 Si. In the preferred example the substrate comprises mainly Ni together with in weight per cent, 4À0 W; 0À025 Mg; 0À035 Si and non-essential ingredients 0À008 Al; 0À20 C; 0À06 Co; 0À10 Fe; 0À05 Mn and 0À008 S.

Abstract: 1,253,057. Airships. E. GELHARD. 31 Oct., 1968 [31 Oct., 1967], No. 51736/68. Heading B7W. An airship has a propulsion channel 11 extending the length of the hull and opening at the nose and tail, a propulsion unit 12 mounted in a forward region of the channel, and a plurality of manoeuvring nozzles 16, 16a, 17, 17a, all communicating with the propulsion channel aft of the propulsion unit and arranged in at least two groups spaced respectively forward and rearward of the longitudinal centre of the hull,' each group having manoeuvring nozzles arranged for upwards, downwards and sideways thrust to each side, and each said manoeuvring nozzle being independently controllable. The manoeuvrability is effected by an independently operable air compressor in each duet. The ducts 17, 17a at the tail penetrate tail fins of the airship. The propulsion channel 11 opens in the tail into a plurality of branches the diameters of which increase towards the outer end. Further ducts 23 are provided, those forward of a stalling edge 25 are connected with a channel 46 concentric with channel 11 and under suction from units 12 and thus suck in air from the surface of the airship whilst those to the rear of the edge 25 exhaust gas over the airship surface. These latter are connected direct to the channel 11. By having opposite flows of air over different portions of the hull surface frictional resistance by the air. is reduced. These further ducts comprise radial hollow struts (see 231, 232, Fig. 12). These struts 231 are joined at their radial outer ends by an annular rib member 27. The rib 27 has a channel 26 extending around its outer circumference and which is covered by perforated plates 30. The inner circumference of rib 27 comprises a plurality of arcuate channels 34, 34a (Fig. 12). The hollow strut 231 communicates with atmosphere through an arcuate channel 34 and channel 26. The central portion of rib 27 is designed to restrict airflow. The airship is provided with a plurality of mutually isolated gasholders of flexible material. They are mounted between adjacent radial strut sections and preferably have an inner wall concentric with the propulsion channel; they also have an internal flexible wall thus providing two compartments whereby either the whole of the tank may be filled with helium or compressed air may be fed into the lower of the compartments. The hull is provided with retractable landing gear. The power units may be jets, turbines or piston engines driving compressors. The hull is constructed from a double-layered skin. Consequently exhaust gases may be conducted between the layers to prevent icing-up of the outer skin.
