Abstract: 1488393 Pipe couplings; rivets RAYCHEM CORP 9 Oct 1974 [9 Oct 1973 (2)] 43684/74 Headings F2G and F2H [Also in Division B3] A coupling device comprises a first heat shrinkable or heat expansible member 10 made from a memory metal and a second, sleeve member 20 positioned respectively inside or outside member 10 so as to be in contact with member 10 or so as to be contacted by member 10 during the process of heat recovery forming a coupling between members such as pipes 21 and 22. The surface of the sleeve member 20 cooperating with member 10 may additionally have internal or external radially projecting teeth 23 of square or triangular cross-section to incise pipes 21, 22 upon recovery of member 10 or alternatively sleeve member 20 may be made of a gall-prone material such as titanium, aluminium, magnesium and zirconium which promote effects such as local welding of the interface between the components over and above normal frictional effects. The sleeve member 20 may also be weakened either by incorporating longitudinal slits or flats in the walls thereof or by tapering the thickness of the walls to promote selective collapse of the sleeve upon recovery of member 10. A further auxiliary sealing ring, which may itself incorporate teeth, be gall-prone or be coated to enhance sealing, may be inserted inside the sleeve. A rivet 86 has a hollow stem 87 forming a tubular section 88 to receive a heat recoverable driver 89, the stem 87 having a greater diameter adjacent the end cap than at its opening as shown before recovery in Fig. 14a. On reaching its transition temperature the driver 89 expands to complete the riveting operation as shown in Fig. 14b.

Abstract: 1490736 Recording and playback INTERNATIONAL STANDARD ELECTRIC CORP 17 Oct 1974 [17 Oct 1973] 44990/74 Addition to 1473931 Heading G5R [Also in Divisions H3-H5] In a film sound signal recording system in which lower frequencies are recorded direct together with amplitude information of a number of partial frequency ranges of the higher frequency band of the signal which are recorded as sequential modulations of a sub-carrier, and which are used to modulate substitute signals to synthesize the higher frequency ranges on reproduction, a reference signal is recorded on the feed track of the film to be used to switch the sequential modulation into the appropriate channels for reproduction. As described the reference signal can be produced by blocking the feed track so that the reference signal is produced optically by the feed sprocket holes. Alternative a line putters synchronized with the feed sprocket hole spacing can be produced, which is reproduced by a light source LQ, a mask BL and light detector LP, the mask carrying a reference line pattern which extends over a distance equal the feed sprocket pitch so that passage of the feed sprocket hole does not modulate the light detector output. The detector output is fed via a phase shifter 16 to a phase comparator 12 where it is compared with the signal from a shift register Z which is stepped by oscillator 15, and the frequency of the oscillator 15 is controlled by the output of comparator 12 to phase lock the stepper of shift register Z to the reference signal from the film feed track. The output from the stages of shift register Z control gates feeding the partial band amplitude signals to respective synthesizer channels of the type described in Specification 1,424,133.

The starting material may be stoichiometric or non-stoichiometric uranium dioxide (in the latter case it is first reduced in hydrogen at 600 DEG  to 800 DEG  C.), or a higher oxide (also first reduced in hydrogen at 600 DEG  to 800 DEG  C.).  Preferably the uranium dioxide is stabilized by heating in hydrogen at 1100 DEG  to 1400 DEG  C., after any necessary reduction but before mixing with the other materials. From 1 to 4% by weight of camphor may be added as the binding agent, and from 0.2 to 0.8% by weight of stearic acid may be used as lubricant.  The binding agent and lubricant are removed by heating at 325 DEG  to 375 DEG  C. for 1 to 3 hours.  Examples are given.

Abstract: 1,029,569. Transistor amplifier circuits; telephone subsets ; loud - speaker circuits. WESTERN ELECTRIC CO. Inc. Dec. 4, 1962 [Dec. 12, 1961], No. 45725/62. Headings H3T, H4K and H4J. A transistor amplifier uses a symmetrical transistor which feeds the load by means of windings respectively connecting the " emitter " and the " collector " to the supply terminals. Thus the circuit will amplify signals applied to the base, irrespectively of the polarity of the supply. The windings may be coupled to respective output windings connected in series to the load or to a common output winding or they may be the windings on a loud-speaker. When the invention is used in a telephone sub-set the signal may be received along the same circuit as the power supply.

Filed: 1967-10-06
Abstract: 1,160,785. Selective printing. SCM CORP. 6 Oct., 1967 [26 Oct., 1966], No. 45918/67. Heading B6F. [Also in Divisions G4 and H3] Continuously rotating machines.-Variations in speed of a recording member, e.g. a type wheel 20 or an endless band, caused by fluctuations in power supplies, are sensed and a continuous and automatically regulating actuation time of a hammer is determined so that impression is accurately formed. The variation in speed of the type-wheel or drum 20 is sensed by a clock wheel 56 with notches 57 corresponding in spacing to that of the characters. A read-head 58 generates a sine wave output, the frequency of which is directly proportional to the speed of rotation of the shaft 24. The normal time of travel of the print hammer 36 is constant and if the type-wheel is rotating at constant speed, impact is correct. Should the speed decrease, the time duration of a pulse generated by 58 is longer. This pulse A, Fig. 1, is applied to a gate 60, a single-shot multivibrator delay circuit 62, and one input of a coincidence circuit 64. The other input is the incoming print signal D. A proportional time delay circuit TD with a condenser 70 in response to the length of the signal E provides an output signal H so that the hammer is activated later. The reverse applies if the speed of the type-drum is increased.

In a marine, pressurized water, integral reactor, the heat exchangers are supported from an annular ring member, forming part of the pressure vessel, and mounted and sealed between the upper and lower parts of the vessel. The exchanger inlet and outlet tubes pass through the annular member together with the control rod driving shafts. Pressurization is effected by electric heating of the water free surface, to inhibit boiling. The pressure vessel is lined internally with stainless steel and thermal insulation. The coolant circulators are mounted on the pressure vessel upper member. The annular ring also supports the core and the latter rests at the base of a vertical tubular member, the upper rim of which is flanged and is carried on an internal shoulder in the ring member. The pressure vessel can be constructed of segments, held together by prestressed tendons. The pressure vessel may be enclosed in a caisson submerged in neutron absorbing liquid which will reduce nuclear activity in the event of a pressure vessel failure. In one embodiment, Fig. 5, the annular ring 13 is clamped between the top closure 30 and the body 11 of the pressure vessel enclosing the fuel assemblies 19. The ring carries the core support 15 on the shoulder 4, and the heat exchanger 13a, and is penetrated by inlets and outlets 79 for the secondary coolant. The control element operating rods 95 are positioned by the rotary shafts 96 penetrating the ring 13. The electric heater 103 evaporates water entering the tube 104 and generates a vapour pressure, thus inhibiting boiling in the reactor core. The spray ring 108 directs cold water into the pressure vessel and may be used to reduce vapour pressure.
