Title: Apparatus for driving members, such as anchors, or piles, into soil, earth, sediment or like materials
IPC: E02D5/80
Filed: 1970-02-13
Abstract: 1293967 Embedment anchors BOLT ASSOCIATES Inc 13 Feb 1970 [14 Feb 1969] 7171/70 Heading B7S [Also in Division E1] Embedment of a disc-like anchor 28 in subaqueous ground is effected by apparatus comprising a ram 14 engaging with a guide sleeve 26 on a tripod 24 and a socket 27 in the anchor, the ram being driven downwardly by reaction to periodic discharge of compressed air from an electrically-controlled device 18 within a waterfilled open-topped barrel 12. The anchor is temporarily attached to the ram by tabs 29, 29<SP>1</SP> which when the anchor has reached the desired depth in the ground are broken by withdrawal of the ram with the aid of a cable 40. A mooring line 30 is secured to one side of the anchor so that after the ram has been withdrawn and the apparatus removed from the site the anchor can be turned into a position substantially perpendicular to the line by applying tension to the latter, Fig. 9 (not shown). Turning of the anchor may be facilitated by securing the line 30 thereto with chains 66, 66<SP>1</SP>, 6611. The line 30 is temporarily secured to the barrel 12 by retaining means 34, which can be actuated to release the line when the anchor has been driven. The device 18 is attached to a rod 20 that is slidable in a bore within the ram so that with the aid of the cable 40 the device can be raised above the barrel for testing purposes. A stop 22 prevents the rod being separated from the ram and facilitates withdrawal of the latter. The device 18 may provide acoustic signals to ensure accurate siting of the apparatus (and the anchor thereon) while the apparatus is being lowered on the cable 40 from a surface marine-vessel, Fig. 6 (not shown).

Title: New azo-dyestuffs containing haloacylamino groups and their manufacture and use
Filed: 1958-03-06
Abstract: The invention comprises azo dyestuffs of formula: R1-N=N-R2-NH-CO-CH2CH2-Halogen in which R1 is an aromatic residue of the benzene or naphthalene series or an azobenzene residue which contains at least one sulphonic acid group for each aromatic 6-membered ring and R2 is a p-phenylene residue.  The dyestuffs are prepared by acylating aminoazo dyestuffs of formula R1-N=N-R2-NH2 with an anhydride or halide of a b -halopropionic acid.  The dyes give yellow shades on animal, superpolyamide and cellulose fibres. The dyeings on cellulose fibres may be fixed by heating in the presence of an acid-binding agent.  In examples the aqueous solutions of the dyestuffs, 2-amino-naphthalene-4 : 8-disulphonic acid or aniline-2 : 5-disulphonic acid or 4-amino-1 : 11-azobenzene-3 : 41-disulphonic acid, 3-acetylamino-aniline, are treated with a solution in toluene of b -chloro-or -bromo-propionyl chloride in the presence of sodium carbonate.  Further examples and many components for the preparation of the dyestuffs are specified.

Title: Voltage control apparatus for an x-ray tube
IPC: H05G1/32
Filed: 1975-02-21
Abstract: 1458172 Automatic control of voltage and current SIEMENS AG 21 Feb 1975 [10 May 1974] 7494/75 Heading G3R The voltage across an X-ray tube is regulated by adjusting the tube treating current. The actual value of the tube voltage is compared with a set desired value to produce a control signal which varies the heating current, thereby varying the tube current and effectively changing the tube voltage in order to maintain it at the set value. The actual heating current is also compared with a set desired value and may be regulated independently of the tube voltage. As shown, an X-ray tube 1 receives a high voltage supply from a transformer 2. A detector 6 produces a signal indicative of the actual tube voltage for comparison in a circuit 9 with a desired value set in a circuit 11. The resulting difference signal is supplied through a PI controller 13 to an amplifier 27, the gain of which is determined by the setting.of a heating current desired value circuit 30 which is ganged with the setting circuit 11. The actual filament heating current supplied to the tube 1 is measured by a resistor 20, the voltage across which is fed through a squaring circuit 21 and cyclically reset integrator 23 to produce a signal 24 indicative of the RMS value of the heating current for supply to the amplifier 27. The output signal from the amplifier passes to a threshold trigger circuit 32 which controls a transistor switch 18 connected in series with the heating current supply transformer 16. In operation, the heating current can be regulated at the appropriate value before the tube is connected to the high voltage transformer 2, and a timing circuit can be used to hold the switch 18 on for a predetermined time to ensure rapid heating of the filament 15 when the tube operational conditions are being changed. The switch 18 may be shunted by a capacitive circuit for absorbing switch-off voltage peaks, Fig. 3 (not shown).

Title: Monitoring the paths of movement of a tool carrier of a machine tool
IPC: G05B19/4068
Filed: 1974-02-22
Abstract: 1457349 Monitoring numerical control machine INDEX-WERKE KG HAHN & TESSKY 22 Feb 1974 [8 March 1973] 8157/74 Heading G3N The operation of a numerically controlled machine is checked by, during a first programming pass, making a recording corresponding to relative motion of tool carrier and workpiece, and, during subsequent passes, scanning the recording to provide a signal should any deviation, or deviation greater than a permissible tolerance, occur. The signal is used to stop the machine. The recording 14 Fig. 4, may include distinct line types 21, 23 for machining, resp. rapid, feedrates, the machine being stopped should line type 21 be followed at a higher speed than a pre-set maximum. A separate recording may be made for each cartesian component of the relative motion, Fig. 6 (not shown). A common carrier 22 supports, angularly displaced with respect to each other, a tracing pin 16 for making the recording, and an optical head 18 coupled to the numerical control unit 32 for scanning it, one or other of pin and head being located perpendicular to the recording for use, Figs. 1, 2 (not shown). During recording, when feedrate is at machining value, coil 25 is energized to oscillate pin 16 to provide the broken line 21. During scanning the frequency of the signal produced as head 18 moves over a broken line is compared with a predetermined frequency, the machine being stopped if such frequency is exceeded. Nut 36 enables pin 16 to be withdrawn prior to a change to or from recording. Head 18 is connected via lead 30 to the numerical control to stop the machine in the event of a deviation. Pin and head are mounted on the upper slide 68 Fig. 5 of an indexable turret lathe with tools 64 to operate on workpiece 58 and facility is provided to make inching movements a between repeating drilling operations (i.e. during turret indexing), so that a separate line 80 is drawn on record 14 for each operation, inching movements, and end-of-pass return movement b, being under program control. In Fig. 6 (not shown) two common carriers (90, 92) with respective heads and pins are provided on lower and upper slides, and co-operate with corresponding recordings (86, 88). Magnetic, electrostatic, or optical recording techniques may be used, or there can be mechanical scanning of an engraved recording. Either workpiece, or tool may move.
