Title: Improvements relating to insulated metal objects
Inventor: BARNEY DUANE LOWELL
IPC: C03C4/00
Filed: 1962-10-12
Abstract: A layer of insulation on the surface of a metal object is formed by applying a solution of glassy sodium phosphate to said surface and curing to a hard glassy substance.  The sodium phosphate used is in the range 1Na2O/1P2O5 to 1.4Na2O/1P2O5, in particular, hexametaphosphate or metaphosphate.  Aqueous solutions of 25-50 parts by weight phosphate to 100 parts by weight water are used.  Curing temperatures range 475-800  DEG C. for 1/2 -10 minutes. Coatings may be used as the insulation for steel laminations, and to construct magnetic cores for electrical apparatus, to inhibit the flow of eddy currents.  The solution may contain a filler material, e.g. silica aerogel, to increase the gap between successive coated laminations where extra spacing is required.  It is stated that the annealing of laminations produces an oxide coating with which liquid sodium phosphate reacts.

Title: Remote steering gear for watercraft
IPC: F15B7/00
Filed: 1970-08-13
Abstract: 1357898 Steering gear A W BARKER 5 Aug 1971 [13 Aug 1970] 39033/70 Heading B7V [Also in Division F1] A device for transmitting the position of a control member, such as a steering wheel in a light watercraft, to an actuated member, such as the craft's rudder, comprises a transmitter unit, Fig. 3, having a piston 4 over which a cylinder 1 can reciprocate in response to movement of a steering wheel, the transmitter unit being in telemotor communication with a receiver unit, Fig. 10, in which a piston 39 reciprocates in response to movements of the transmitter cylinder 1 thus to move a rudder. The transmitter unit comprises a piston-rod 5 held in an end body 7, the cylinder 1 being supported for reciprocation with a housing 8 integral with the body 7. A steering wheel is connected to a shaft 12 having gear teeth 11 which engage teeth 10 on a guide rib 9 of the cylinder 1, the rib 9 extending through a slot in the housing 8. Hence steering wheel movement effects reciprocation of cylinder 1. The piston-rod 5 has located therein a sleeve 21 also secured to the body 7. The rod 5 thus encloses two passages, the axial passage 22 within sleeve 21 and an annular passage 23 between the sleeve and the rod 5. The passage 22 communicates with the chamber 2 at the left-hand side of piston 4 (Fig. 3) and with a passage 26 in body 7 which leads to an inlet/outlet port 27. The annular passage 23 has orifices 44 communicating with chamber 3 and the other end communicates with a port 32 in body 7. Ports 27, 32 communicate with ports 42 and 43 respectively of a conventional piston and cylinder 39, 35, Fig. 10. Thus it can be seen that movement of cylinder 1 by a steering wheel to the left say, Fig. 3, decreases the volume of chamber 3 and increases the volume of chamber 2. The receiver unit 39, 35 correspondingly moves to the right, Fig. 30, to increase the volume of chamber 41 and decrease that of chamber 40. The piston-rod 38 transmits such movement to a rudder. Various control devices for the system are also described (Figs. 4 to 9, not shown).

Title: Methods of monitoring the thickness of a transparent film
Inventor: CLARK CONRAD ALBERT
IPC: C23C16/52
Filed: 1969-08-05
Abstract: 1283111 Measuring thickness photo-electrically WESTERN ELECTRIC CO Inc 5 Aug 1969 [9 Aug 1968] 39053/69 Heading G1A [Also in Division C7] In apparatus for monitoring the thickness of a coating being deposited on a substrate which is hot enough to radiate light through the coating, a second similar substrate is mounted adjacent the first substrate and has a thin transparent control film on its surface under the coating so that the variation in the intensity of light received after passing through the coating are compared until a relationship indicating a predetermined coating thickness is obtained. As shown, substrates 1, 1A are located inside deposition chamber 2 and are heated to 900‹C. when light of 6000A wavelength is emitted and focused by lenses 4, 4A on to photo-detectors 5, 5A. The photo-detector outputs are fed into difference amplifier 7 whose output is monitored by known means. A control film 8 of known thickness is deposited on one substrate 1A so that the resultant curve of intensity of radiation against coating thickness is different to that of the bare silicon substrate 1, see Fig.2. Since it is advantageous to determine a zero output from amplifier 7 which corresponds to the required coating thickness, the crossing point of the curves in Fig.2 can be adjusted by altering the control film thickness or by varying the ratio of the input or output of the detectors. Alternatively the control may respond to a second null point which corresponds to the required thickness. Filters 10, 10A may be used to restrict the wavelength transmitted to the detectors to give sharper results. In a practical embodiment, Fig. 3 (not shown) a plurality of silicon substrates are mounted on a rotatable carrier, one substrate being provided with a control film. A single photo-multiplier monitors the radiation from each substrate once for each revolution of the carrier and its output is applied to amplifiers by cam operated switches when the control film substrate is aligned and when one other substrate is aligned. Each output is stored and applied to the input of an amplifier chain whose outputs are compared. When the difference is zero the deposition process is stopped as the required thickness of coating has been deposited.

Title: Modulatable high voltage power supply
IPC: H02M3/07
Filed: 1975-09-24
Abstract: 1519998 High voltage supplies for cathode ray tubes UNITED TECHNOLOGIES CORP 24 Sept 1975 [30 Sept 1974] 39148/75 Heading H2F A high voltage supply for a cathode ray tube 24 comprises a high voltage D.C. power supply 10, a high voltage step up transformer 14, 18, and a capacitor 22, the D.C. voltage across the capacitor being coupled to a control input 36 of the high voltage power supply. A pulse generator 20 supplies low voltage positive pulses so that the capacitor 22 charges to a positive voltage which is supplied to the input 36 of a differential amplifier 38 via an inverter 49. The voltage multiplying factor of the supply 10 equals the turns ratio of the transformer 14, 18 and the output voltage of the supply 10 is added to the stepped up voltage across the transformer secondary winding. The capacitor voltage fed to the supply 10 corrects the output voltage of the supply so that in the event of a change in the duty cycle of the pulses provided by the pulse generator 20, the swing of the high voltage supply to the anode of the cathode ray tube remains centred on a fixed value. In a modification, the circuit supplies high voltages to both the anode and the focus mechanism of the tube by using two supplies 10 and two secondary windings on the transformer.

Title: Improvements in and relating to semi-conductor devices for emitting radiation
Inventor: SYMS CHARLES HENRY ANTHONY
IPC: H01L33/00
Filed: 1964-09-29
Abstract: <PICT:1094061/C4-C5/1> A semi-conductor device for emitting radiation comprises a semi-conductor wafer 1 having a PN junction 2 therein extending in a plane substantially perpendicular to the plane of the wafer and dividing the wafer into a P-type region and an N-type region, and electrical contacts 3, 4 attached to the two regions, both contacts being disposed on one principal surface of the wafer. The contacts are preferably of semi-cylindrical form, as shown, separated by a layer 5 of insulating material such as mica, the wafer being alloyed to the end faces of the contacts which may be cut obliquely so that the radiation, which is emitted principally at an angle to the plane of the junction, is directed along the axis of the contacts.  The contacts make good thermal connections with the wafer in order to dissipate heat generated during operation of the device. If the device is to be used at very low temperatures, mechanical stresses due to differences in the thermal expansion of the wafer and the contacts are avoided by replacing one of the semi-cylindrical contacts by a wire attached to the wafer at a distance from the other contact. Alternatively, one contact may be alloyed to substantially the whole area of one region of the wafer and may have a plane face extending over, but not alloyed to, a substantial portion of the other region of the wafer, the second contact taking the form of a wire attached to the other region.  In this way the first contact has a good thermal connection with the second region of the wafer but is electrically insulated therefrom.  A preferably transparent coating of silicon monoxide or shellac may be applied to the exposed surface of the wafer.  In one method of making an infra-red radiating device, a block of gallium arsenide of one conductivity type is diffused with zinc to form an outer layer of opposite conductivity type and is cut several times to form a wafer divided by a PN junction.  Brass contacts are then alloyed to the wafer using gold, silver, copper, tin or indium, lead alloys of these materials, or indium-gallium alloy.  Finally, silicon monoxide is evaporated on to the exposed surfaces.  Other III-V semi-conductors may be used for infra-red radiation, for example compounds of Al, Ga, In and N, P, As, Sb or mixtures of these compounds.  II-VI Compounds may be used for radiation on other wavelengths.

Abstract: 1367682 Polymer compositions; removal of volatile constituents FRENCH OIL MILL MACHINERY CO 25 Aug 1971 [4 Sept 1970] 39990/71 Heading B1B Polymer composition is freed from volatile constituents such as solvents by feeding it into the hopper 10 of a cylindrical screw press containing several screw members rotated on shaft 15, introducing a desolventizing agent (such as nitrogen, steam or water) into the compressed composition through an injector 25 in one of a series of lugs 23 surrounding collar 22, mechanically working the mixture by the notched flights of member 32 in section 30, whereby the mixture is heated, and then forcing it through annular orifice 42 between ring 40 and collar 35 into vent section 50 where volatile constituents are vaporized and flow through slits between parallel bars to housing 54 where the vapours are removed to a recovery system. The screw flight in section 50 has greater pitch and smaller body diameter than in the preceding sections. The polymer is then conveyed through three further sections 60, 70, 80 wherein addition of desolventizing agent, mechanical working, and venting of vapours respectively are effected similarly. The polymer is next conveyed through section 85 to rotating knife 95 at the end of the apparatus. The slices of desolventized polymer are fed into the inlet hopper 102 of a further screw press apparatus, provision being made for addition of a compounding substance, such as oil, through injector 107. Thermocouples 112 are placed at the annular orifices provided by rings 40 and 75; and these thermocouples may control motors 46 and 76 which adjust the longitudinal position of the rings and the opening or closing of the corresponding orifices. Liquid may be sprayed into housings 54 and 81 through spray heads 120 to prevent fine particles reaching the solvent recovery system. Solid compounding agents, such as carbon black or zinc oxide, and oil may be added to the polymer composition before desolventizing. A sulphur accelerator may be added to the desolventized polymer before it is discharged from the apparatus.

Abstract: 926,225. Casting concrete pipes in the ground. FULLERFORM CONTINUOUS PIPE CORPORATION. Nov. 25, 1960, No. 40663/60. Class 20 (2). A concrete pipe is laid in a pre-dug ditch 10 by a machine towed by a cable 21, the pipe being cast in two halves, first the lower half 11 and then the upper half, the two sections being supported until set by an inflatable core 43. A cement mixture is supplied to a hopper 29 with a partition 39; the cement between the partition 39 and a baffle 19 falls over the plates 45 of a tube 28 and is tamped down between the bottom of the ditch and a supporting member 24 by bars 99 which are driven by a motor 89. As the machine is towed along, the core 43 which is anchored to the end of the ditch, slides out of the machine to support the pipe, and the partition 39 screeds off the edge 44 of the lower part of the core. The cement between the partition 39 and a baffle 32 is applied directly to the top of the core 43 and the edges 44, is tamped down by bars 100, and is screeded off by the lower edge of the baffle 32.
