Abstract: 1,226,284. Bulking yarns. HEBELEIN & CO. A.G. 16 May, 1969 [22 May, 1968; 7 Jan., 1969], No. 25190/69. Headings D1F and D1W. A high-bulk, low stretch, composite yarn is produced by modifying the crimp of a textured, synthetic, thermoplastic, multifilament yam to a predetermined, controlled value and plying it, e.g. with 50-200 turns per metre doubling twist, with a carrier yarn of manmade, vegetable, e.g. cotton, or animal, e.g. wool, continuous or staple fibres and of low structural elongation. The required crimp may be developed by partial relaxation, e.g. 20-50%, between pairs of rollers, of the tensioned and/or stretched textured yarn, optionally, with heat applied and/or the crimp modification effected along the plying path. The texturing may have been effected by twist or false-twist crimping, edge drawing, asymmetric heating, differential shrinkage of bifilar components, stuffer-box or intermeshing toothed rollers. The degree of crimp modification may be varied periodically or at irregular time intervals to produce yarns varying in bulk. The wound composite yarn may be stabilised by a heat-treatment and at least two similar such yarns may be plied.

Abstract: 1,227,035. Jib cranes. WIKSTRAND & BERG A.B. 21 June, 1968 [21 June, 1967], No 29864/68. Heading B8B. [Also in Division F1] An hydraulic motor 19, Fig. 2, suitable for raising and lowering the lower jib arm 4, Fig. 1, of a mobile crane or an upper arm 5 or for rotation of both arms about the vertical axis of a turntable 3 is supplied by a variable delivery pump 30, Fig. 2, driven by a power take off 36 of an I.C. engine and delivering through a duct 31 having a branch 29 leading to a solenoid actuated by-pass valve 28 and. to an hydraulic motor 34 for varying the speed of drive 36, a volume flow regulator 17, a duct 38 and a solenoid actuated combined inlet and outlet changeover valve 39; the flow regulator 17 being opened against a spring 18 by a yoke 12 to a degree determined by the position of a manually operated arm 10 rigid with a cam disc 11 against which the yoke bears at 15, and the solenoid 26 of valve 28 being energized so as to move valve 28 to a throttling position when switches 22, 23 are closed by cam surfaces 20, 21. In the neutral position shown of arm 10 valves 17, 39 are closed and valve 28 is open. On swinging arm 10 upwardly switch 23 is closed thereby closing a relay switch 51 and energizing the solenoid 43 of valve 39 which is then displaced to the right and at the same time the closing of switch 23 energizes solenoid 26 to close valve 28 and thus connect pump delivery to the motor 34 for increasing the speed of drive 36. Said upward movement of arm 10 also opens valve 17 to a degree dependant of the displacement of the arm beyond its neutral position resulting in forward direction of hydraulic motor 19. Also the speed of the drive 36 is responsive to the setting of valve 17 and hence to the degree of displacement of arm 10. To drive motor 19 in the reverse direction, arm 10 is swung downwardly to close switch 22 and relay switch 24 thus energizing solenoids 44, 26. The hydraulic circuit may also be controlled by an arm 60 and cam disc 61 located on a platform carried by the end of the jib arm 5 and connected to the yoke 12 by an hydraulic link comprising a piston 65 and rod 64 which when moved to the right by cam 61 pressurizes oil in a duct 67 connecting an accumulator 71 to a piston and cylinder assembly 68 within the yoke 12. Three such circuits are provided each comprising a cam disc on the body of the crane and one on the platform 6 and an hydraulic motor 19 which may reciprocate or rotate.

Abstract: 1,228,372. Mole ploughs. A. N. EDE. 1 May, 1968 [3 May, 1967], No. 20476/67. Heading A1B. [Also in Division F2] In a method of trenchless laying pipe 28 a length of flexible sleeving 23 is fed down underground through an advancing mole plough 10 and is progressively laid in position behind the mole in a newlyformed tunnel 16 to line the tunnel as the mole is advanced, the end of the sleeving being anchored, at 29, at, or near, the start of the tunnel, and a length of pipe 28 being thrust forwards from behind the mole plough along the newly formed tunnel and within the stationary flexible sleeving newly laid therein. As shown in Fig. 1 a driving unit 26, having power driven pneumatic-tyred rollers 27, is mounted in a trench 25 to force the pipe length 28 into the flexible sleeving 23 along the underground tunnel 16 behind the advancing mole 14, which is co-ordinated with the driving unit 26 so that the leading end 30 of the pipe 28 follows closely behind the rear end of a delivery duct 17 on the mole. Coordination can be carried out by trailing a marker above ground behind the mole. After the pipe 28 has been introduced into the tunnel the interior of the sleeve 23 may be filled with grout, or cement. The plough arrangement includes a towing tractor 12, a hydraulic lift 11, a hollow coulter 13 and the mole 14, a length of flexible sleeve 23, made e.g. of plastics, being fed, through the duct 17, from a reel 22. In a modification, Figs. 3, 4, which can be used to lay pipes across a river, or under the sea bed, a hollow, triangularly-shaped, framework 40 pivotally supports a hollow coulter and mole 45 which carries a delivery duct 47 for a flexible sleeve 51 and has pivotally mounted, on legs, at each of its forward and rearward ends, a pair of co-axial roller/floats 56 or 63 which assist in floating the mole plough to its position of use and rollingly support it when it is on the sea bed 60. Decking 72 may be laid across the top of the frame 40 which, with the coulter 45, is supplied with bleed holes 71 to allow controlled escape of air introduced from a pipe 70 to make the plough buoyant. For towing the plough on land the pivotally mounted legs 57, 62 for the roller/floats 56, 63 are drawn towards each other and fastened to extend substantially vertically at each side of the plough, to raise the framework 40.

An electric blanket has a heating wire 4 having a heat sensitive layer formed over the entire length of the wire and comprising a flexible solid organic material having a negative resistance temperature coefficient which becomes sufficiently conductive at a determined temperature to pass current to a signal wire 6 which biases a silicon transistor 12-14 to conduct hence energizing a relay coil 16 which through contacts 9 disconnects heater 4 from a supply. The transistor is fed through rectifier 20 and the circuit preferably includes a Zener diode 19 which limits the voltage applied to the transistor and enables a low breakdown voltage transistor to be used. A diode 23 also limits over voltages across the transistor and provides a more stable relationship between transistor collector current and the resistance of the heat sensitive layer 5. The heater current is controlled normally through a bimetallic temperature controller 8 maintaining the blanket body at say 60 C., but if the temperature rises to an abnormal value e.g. 120 C. leakage current causes the transistor and hence the relay 9, 16 to break the heater current. When the layer 5 has cooled again to say 60 C . contact 9 is reclosed.

Abstract: 1,257,121. Measuring emissivity to identify materials. TEXAS INSTRUMENTS Inc. March 19, 1969 [April 14, 1968], No. 14376/69. Heading G1A. The material of a target source 10, Fig. 1, is identified and its temperature measured, by measuring its emissivity as compared with that from a black-body reference source 24, at different wavelengths. In the arrangement of Fig. 1, a chopper 20 and mirror 20a are used to direct to detectors 12, 14, the radiation alternately from the target and reference sources. Filters 16 and 18 define two different wavelengths at which the emissivities are compared. For much more accurate identification, measurements at many more than two wavelenths are used. Amplifiers 26, 38 include rectifiers synchronized with the chopper motor 22 and the output for each is a D.C. signal representing the difference in emissivities of the target and reference. After weighting and logarithmic amplification (36, 46) the signals produced represent the ratio of the emissivities. The sum and the difference of the two ratio measurements are taken by devices 50 and 48. The output at 56 provides a temperature independent signal representative of the composition of the material of the target 10 (when compared with calibration curves) and that at 58 represents the target temperature. The apparatus is calibrated to avoid inaccurracies due to extraneous sources by use of a further reference source, by adjustment of potentiometers 30, 42, 52, 54, and D.C. supply 34, In a modification of the Fig. 1 system to remove the effects of grey bodies (i.e. those with constant emissivity over the frequency band of interest) the outputs of the logarithmic amplifiers of Fig. 1 are connected via variable resistors to three summing networks, Fig. 4 (not shown). In another arrangement, logarithmic amplifiers are not used, Fig. 3 (not shown), but this results in a loss of accuracy as compared with the arrangement of Fig. 1

In the embodiment of Fig. 2 a radio frequency from a roadside transmitter representing the desired maximum or minimum speed is fed to a selector 3 to energize a self holding relay 11, 12 (for minimum speeds), 21 (for maximum speeds) so that a voltage or frequency signal representing the required speed is fed through the selected resistance 7. Relays 21 control the energizing of transistor 10 to give the alarm signal, relays 11, 12 controlling transistors 10, 22 so that an upper and lower limit may be set and the alarm actuated if the speed is not between these limits. A further relay 9 may be used to determine whether a maximum speed is exceeded when only a short distance exists between the entry and the exit points of the speed controlled zone, e.g. at a crossing. The transmitter and receiver arrangements may be replaced by manual selection of the resistors to be switched into the circuit or this manual feature may additionally include (Figs. 3, 4, not shown).
