Title: Improvements relating to machines for grooving or slotting metals
IPC: B23D13/00
Filed: 1946-03-14
Abstract: 609,429. Shaping and slotting. MILLER & CO., Ltd., and STEPHEN, J. March 14, 1946, No. 7946. [Class 83 (iii)] A machine for grooving or slotting is provided with a reciprocating slide, a tool-holder pivotally mounted thereon in which two tools are adjustably mounted at an angle to one another and means for limiting the angular movement of the tool-holder for locking it during travel and for moving it at the ends of its travel, by contact with an abutment on the machine and by spring means, respectively to bring the appropriate tool into operative position. To the slide 7 is secured a block 9 which has flanges 10 and 11 to limit the angular movement of the tool-holder 13 which pivots on a ball-race 15 about a bolt 14. Bolts 20 working in slots 21 clamp the tool 19 in an eccentric bush 17 which is itself clamped in a sleeve 16 by bolts 22. The tool 26 is mounted in a tool-block 24 which is adjustable along a channel 23 by means of a pin 29 projecting from a threaded sleeve 30 working on a screw 31, thus permitting the depth of cut to be adjusted. In operation, a projection 35 strikes an abutment on the machine at one end of the stroke, thus rocking the support and causing a jaw 36 to be forced behind a projection 37 by means of a spring 39 operating against the end of a lever 38. On the reverse stroke, an abutment on the machine strikes the lever 38, thus releasing the jaw 36 and allowing a spring 40 to swing the support to its former position.

Title: Excess Current Detectors
IPC: H02H3/093
Filed: 1968-02-19
Abstract: 1,197,363. Protective arrangements. ELECTRICITE DE FRANCE (SERVICE NATIONAL). 19 Feb., 1968 [20 Feb., 1967], No. 8002/68. Heading H2K. [Also in Division H3] A detector of excess current comprises multiaperture storage core devices in association with a pulse counter. As shown in Fig. 1, a signal proportional to the current in an A.C. line 6 is applied by a transformer 5 to the prime windings of multi-aperture devices 1, 2. The devices are alternately set and cleared by pulses in write and reset windings E and R1, respectively, and if the prime current exceeds a threshold value, a pulse is induced in an output winding S coupling the devices to the write winding E of a further device 3. The preset windings of the first two devices and of the third device, respectively, are energized from different phases of a two-phase pulse source, the third device providing an output in a winding S to a pulse counter 8 under the control of periodic pulses applied to prime winding A<1>. The two-phase pulse source has a higher frequency (e.g. 425 Hz) than the frequency (e.g. SOHz) of the A.C. line current, and so enables the devices 1 and 2 to produce a plurality of output pulses whenever the line current signal exceeds a threshold value, each device being operative alternately in successive half cycles. As the devices are reset and written into at regular intervals, the number of pulses passed to the device 3 in a given half cycle of line current is dependent on the duration, in that half cycle, of excess instantaneous signal values. Device 3 is used for combining the outputs of devices 1 and 2, and its output pulses are counted by the pulse counter 8, an excess current indication being given if a predetermined total is reached within a specified time. It is stated that a substantially inverse error current/time characteristic is obtained. The counter 8 is shown in Fig. 2 and comprises a chain of multi-aperture devices 11-14 . . providing an output at 80. A further multiaperture device 4 serving to reject pulses of marginal amplitude is used in the current detector in this arrangement. To avoid the cumulative totalling of inconsequential transients in the line current, the counter is cleared periodically whenever a phase difference register is empty. All pulses applied by the threshold device 4 to the counter are also applied to the difference register, and since alternate multiaperture devices forming the register are coupled by OR gates to a counter-clearing control circuit 40, clearing of the counter is inhibited while the register is occupied.

Title: Improvements in oxo alcohol quality
IPC: C07C29/16
Filed: 1954-03-19
Abstract: Alcohols are synthesised by reacting an olefin together with a mixture of carbon monoxide and hydrogen in the presence of a carbonylation catalyst, the olefin being obtained by polymerizing one or more lower olefins which have been substantially freed from sulphur contaminants.  In a preferred embodiment the initial olefin stream, consisting of C3 and C4 olefins, is passed through scrubbers containing 7-10 per cent caustic soda solution to free the olefins from sulphur; the olefin stream (now containing less than 10 parts per million of sulphur) is passed into a polymerization unit in which the olefins are polymerized in the presence of a calcined phosphoric acid-kieselguhr catalyst; the polymerizate is distilled to give a cut corresponding to the heptene fraction which is passed into a carbonylation reactor containing a catalyst such as cobalt oleate or naphthenate. Hydrogen and carbon monoxide are passed in at a preferred temperature in the range 300-375 DEG  F. and a pressure of 2500-3500 p.s.i.g.  The product stream is decobalted and then catalytically hydrogenated to give octyl alcohols which may be converted to esters in known manner.  Other scrubbing agents which may be used for removing sulphur from the initial olefin feed are alcohol, amines or water.  If desired, distillation adjuvants may be added to the polymer distillation zone.

Title: Compaction of synthetic textile materials
IPC: D06M101/16
Filed: 1973-02-19
Abstract: 1370293 Reducing fabric porosity MEADOX MEDICALS INC 19 Feb 1973 [23 Feb 1972] 8121/73 Heading DIP A knitted or woven synthetic polymer fabric is made less porous by immersion in a solution containing a minor proportion of a solvent for the polymer and a major proportion of a shrinking agent for the polymer until the fabric has shrunk by 30-41% in the mole direction. Preferably the synthetic polymer is polyethylene terephthalate, poly (1, 4-cyclohexylenedimethylene terephthalate) (kodel, R.T.M.), nylon 66 or polyacrylonitrile (Orlon and Acrilan, R.T.M.'s). The solvent may be hexafluoroisopropanol, hexafluoroacetone propylene adduct, hexafluoroacetone sesquihydrate, benzoic acid, trichloroacetic acid, phenol, metacresol or parachlorophenol and comprises 2 to 10% by weight of the solution. The shrinking agent may be a halogenated aliphatic hydrocarbon having up to 6 carbon atoms, preferably chloroform, methylene chloride, tetrachloroethane or ethylene dichloride. For polyethylene terephthalate the solubility parameter of the shrinking solution should be between 9.1 and 11.0, i.e. close to that of the polymer (10.7) 10% by weight of tris (2, 3-dibromopropyl) phosphate as flame retardant, 4% of unspecified silicone water repellent or 1 % of Latyl Blue BCN (C.I. Dispense Blue 56) dye may be present. The shrinking procedure fixes such additives, render the fabric antistatic and reduce its tendency to snag. As exemplified the fabric is a tube warp-knitted from 40 or 70 denier yarn on a double needle bar Raschel machine with a tricot or lock stitch and is used as a cardic (especially vascular) prosthesis after crimping. Sailcloth, awning and umbrella fabric may also be rendered less porous. The fabric may be shrunk by immersion for 0.5 to 30 minutes in the solution at freezing point to boiling point, preferably 0 to 40C. Numerical readings of the fabric porosity are obtained by the Wesolowski method.

If there is no disagreement in position of the images on vidicons 2a and 2b, no picture is reproduced on monitor 8. Any disagreement causes a picture to be produced on monitor 8, and this disagreement may be removed by adjusting the centring circuit 10 associated with vidicon 2a to extinguish the picture on the monitor. The centring circuit may comprise a vertical centring coil, the D.C. through which may be manually varied, and a circuit in which the amount of D.C. superimposed on the horizontal deflection coil may be manually varied. Alternatively the deflection coils of one vidicon may be mechanically moved. Monitoring tube may be dispensed with and the output of the subtraction circuit arranged to automatically control the centring circuit to maintain registration between the two images.
