A mobile crane comprises a frame 6 rotatably mounted on a chassis 1, and a boom 10 having its foot attached to conveyer means mounted on the frame 6 and adapted to move the boom foot between an operating position in which the boom foot is disposed adjacent the front end of the frame 6 and a travelling position in which the boom foot is disposed adjacent the back end of the frame 6. The boom top 16 has wheels 15 to support it when the boom is lowered and the boom foot is mounted by hinge pins on arms 25 of the conveyer means, the arms being secured to a torque tube rotated by an hydraulic actuator. When the boom is in the operating position it is releasably secured to the frame 6 by spring- loaded T-bolts. The frame 6 also supports a lowerable A-frame 43 as described in Specification 1,145,606. Rollers 63 rotatably mounted on the frame 6 are engaged by tracks on the boom to support the latter as the boom foot is moved to the travelling position. Between the rollers and rotatably mounted thereon is a boom stop cable drum, Fig. 7 (not shown). Inside the said drum is a return spring drum and a return spring has its ends respectively fixed to the two drums. The stop cable is secured to the boom 10 and prevents the latter being raised beyond a safe working angle. Resiliently mounted rollers 82 support the boom in its travelling position and a pan 84 on the boom supports a cable 53 and a bridle 54. In a second embodiment, Figs. 9, 10 (not shown), the boom foot is secured to a pair of conveyer chains which move the foot. The rollers 63 are mounted on a member telescopically adjustable relative to the frame 6 by manual, hydraulic or mechanical means.

Filed: 1965-12-14
Abstract: 1,124,590. Knitting machines; spinning yarns. JACHONIC Ltd. 13 March, 1967 [14 Dec., 1965; 14 May, 1966], Nos. 53016/65 and 21522/66. Headings D1C and D1F. [Also in Division G1] The speed at which yarn or thread is fed to a textile machine is measured by replacing the yarn or thread with a marled measuring yarn and determining the frequency with which the marls pass a photoelectric scanning head. The desired speed for correct operation may be predetermined by performing the textile operation on the yarn or thread normally used, adjusting the machine to produce an acceptable product, replacing the yarn or thread with the marled yarn and measuring the speed corresponding to the correct setting of the machine. The invention may be applied to textile machines producing a fabric from, or merely operating on a yarn or thread e.g. weaving, weft and warp knitting on circular, flat or straight-bar machines, warping, sewing, braiding, winding and false twisting. The photoelectric scanning head comprises a block 2 fig. 2 of black Perspex (Regd. Trade Mark) having a lamp 6 and a photoresistor or phototransistor 7 in bores 5 which communicate by bores 8 with a groove 3 shaped to take the marled yarn 1 without damaging it. The block is covered by a snap-on chromium plated brass cover 4. The cell 7 is connected by a transistor amplifier to a counter or a speed indicator, fig. 3 (not shown). If the yarn speed is too high for accurate detection of the marls by the scanning head, it may be apparently reduced stroboscopically by flashing the lamp 6 or inserting a rotating apertured disc between the yarn and the cell 7.

Abstract: 1311314 Harvesters DEERE & CO 4 Dec 1970 [26 Oct 1970] 57729/70 Heading A1F In a cotton harvesting machine the front ends of the two harvesting units 13 are raised and lowered in response to movement of the ground engaging feelers 40 by hydraulic rams 30 turning the harvesting units 13 about their support pivots 16 until the movement exceeds predetermined value when the harvesting units are raised or lowered bodily by hydraulic rams 20 acting on support arms 14. The movement of each feeler 40 is transmitted through adjusting rod 42 and rack arm 44 to valve 50 controlling ram 30. The ram 30 tilts the harvesting unit 13 via rod 34 and rock arm 35 and also moves cam arm 73 through linkage 70-72. A cam following system bearing against arm 73 is connected to a push rod bearing on one end of the spindle 22 of valve 21 which controls ram 20. The length of cam surface 76 determines how far ram 30 can tilt the harvesting unit before surface 75 or 77 is engaged and valve 21 is moved from "neutral" to "raise" or "lower" position. The harvesting units may be lowered or raised for transport by hand lever 24 connected to valve spindle 22. When the harvesting units are fully raised the tension is relaxed in springs 81 which bias the valve spindle against the push rod and thus the valve can then be set in "neutral" by lever 24 and will remain there with the harvesting units raised.

Abstract: 1381602 Semi-conductor devices INTEL CORP 21 Dec 1971 [28 Dec 1970] 59413/71 Heading H1K In an integrated circuit having a gate, source, and drain formed on a substrate of e.g. monocrystalline (III oriented) Si, a SiO 2  layer 12 (Fig. 1c), is thermally grown or deposited and is removed by etching over photo-resist to form openings 16 in the oxide layer to expose surface 18, which is again oxidized to form a thin layer 20 in the openings. This layer is selectively removed by etching over photo-resist to expose the surface in areas wherein semi-conductor devices or parts thereof are to be formed, e.g. at 22, for source or drain, and an overlying layer of Si is deposited (Fig. 1d, not shown), e.g. by sputtering or pyrolysis of SiC 4  and H 2  to penetrate opening 22 to contact the surface 18, so as to form a continuous contact, interconnection and gate. The layer 24 is monocrystalline in contact with the surface 18 and polycrystalline overlying the oxide layers 12, 20. Si 3 N 4  may be interposed between the silicon and oxide layers if required, and the overlying Si layer is etched with HF, HNO 3 , CH 3 COOH and I over photoresist to remove it except for that which forms gates, contacts and interconnections; and also for removing the exposed thin oxide layer 20 where source and drain and any diffused resistors are to be formed at openings 30, 32, 34 (Figs. 1e, 1f). A gate 36 and contact 40 are formed by the etching of the overlying Si layer, and the contact 40 is interconnected over 38 to the gate 42 of an adjacent similar device. The exposed underlying thin oxide is etched out with ammonium bifluoride to expose the surface 18 on each side of gate 36 except for the contact areas 40, at openings 30, 32, 34, allowing indiffusion of impurities to form source and drain regions 44, 46, 48; while the impurities are also diffused through the Si contact 40 to form source or drain region 50. P may be used for N type and B for P type regions. The surface is then covered with SiO 2 , glass or other insulant into which openings are photo-etched for contact with underlying Si elements, and Al is evaporated on to enter the openings. Required interconnections are produced by etching the Al layer over photoresist and a further protective layer of glass is deposited and patterned by photoresist etching to expose bonding pads for wire connections. The device may be subsequently annealed, and in final form is shown in Fig. 2, wherein Si wafer 10 has N type source and drain regions 48, 50 and is overlain by insulant film 12, with a thinner overlying layer 20 between the source and drain regions. A doped Si gate electrode 36 is formed on layer 20, and region 50 has a contact 40 of, e.g. Si, continuous with connection 38 to the gate of an adjacent device.

Abstract: 1435397 Tape recording; control of displays J J DAMLAMIAN 27 Dec 1973 [26 Dec 1972] 59729/73 Heading G4H Analog data ARZ recorded on magnetic tape is associated with digital data FNRZ, SNRZ which is used for controlling a display. Each item of analog data ARZ (relating to, e.g. music, or a scientific course) is associated with a "heading preamble" PR and a "start record zone" SNRZ (for tape playback) and an "appendix" AP and a "final record zone" FNRZ (for tape rewind). SNRZ, FNRZ could be data relating to a piece of music, or mathematical or chemical formulae; the data is fed via buffer and shift registers 22, Fig. 3 (not shown), to a digital image converter (58) which generates signals suitable for controlling an alpha-numeric display (e.g. liquid crystal). In the playback mode for analog data (ARZ) n+1  the preamble PR n  causes the image converter (58) to be activated after a delay sufficient to by-pass FNRZ n . The digital data (SNRZ) n+1  is then read and stored and then displayed during playback of (ARZ) n+1 . The subsequent peramble PR n+1  resets the converter. In the rewind mode for ARZ n , appendix AP n+1  is used to activate the converter (58) after a delay sufficient to by-pass SNRZ n+1 , then FNRZ n  is read and displayed during playback of ARZ n . The next appendix AP n  resets the converter. A description is also provided of the composition of the digital data (Figs. 2, 5, not shown) of the synchronization of the digital playback (Fig. 4, not shown) and of the recording/playback head of the tape recorder used. A keyboard (23) and associated buffer and shift registers (21) may be used to record digital data on the tape, which data may also be supplied to converter (58).

Abstract: 1459229 Photo-electric fluid analyzers M SCHUMAN 28 Dec 1973 [59977/73 Heading G1A A compressible analyzer comprises means for alternately circulating hot and cold volumes of the fluid through an optical chamber and means for monitoring the cyclical variation of spectral radiance in the chamber. As shown, fluid is circulated through an optical chamber by a pump 4 and distributed alternately  by a rotary valve 7 through a cold return circuit and a hot return circuit. The cold return circuit includes a heat exchanger 14 in the form of pipes 15 provided with fins 17 cooled by fan 18. The hot return circuit includes a chamber 19 surrounding a lamp 21 having external fins 20, the radiation from this lamp being directed into the optical chamber 2. A first pair of detectors 26, 27 provided with optical filters 24, 25 view the optical chamber, which has a reflecting interior, through window 23 and the signals are processed to give a measure of the concentration of a component of the sample. The system is connected to a constant pressure sample environment, e.g. the atmosphere, by open conduits 1, 15 so that the circulating fluid remains at constant pressure. Since the fluid is compressible the sample concentration varies inversely with the temperature so that the variations in the intensity of the emitted radiation are 180 degrees out of phase with the variations in absorption, this resulting in in-phase effects on the intensity of the radiation received by the detectors. The detector signals are synchronously demodulated using a reference signal derived from a temperature sensor 29. The output signal may be compensated for temperature variations and also for pressure variations detected by a sensor 31. Pressure fluctuations due to operation of valve 7 may also be used to provide the synchronous demodulator reference signal. Further detectors may view a second window 32 to simultaneously measure the concentration of a second component of the sample or to provide a second measurement of the first component at a different wavelength band. A valve 50 may be incorporated to close the inlet during the first part of the heating cycle to permit measurements of emission bands to be made at constant concentration. If desired the whole of the hot cycle can be at constant volume (concentration) with the cold cycle at constant pressure. The light source 21 may be a pressure broadened or unbroadened arc lamp or a spectral lamp emitting in the visible, UV or IR regions and the radiation may be modulated by a chopper in front of the input or outlet windows or by modulating the source supply. For emission investigation the source 21 may be omitted. The detectors may be "flake" detectors or pneumatic detectors. The filters may be of the gas cell type or a filter wheel may be used. Collimated optics may be provided. The processing circuit may utilize a differential amplifier, a bridge or a divider to combine the outputs of the two detectors.
