Title: Methods and apparatus for Borehole Drilling
Inventor: WHITTLE FRANK
IPC: E21B19/08
Filed: 1966-04-27
Abstract: 1,156,134. Measuring bit pressure electrically; dynamometers. BRISTOL SIDDELEY ENGINES Ltd. April 26, 1967 [April 27, 1966], No.18516/66. Headings G1N and G1W. [Also in Division E1] Optimum bit penetration is obtained during drilling by applying a higher bit weight than necessary, drilling with the draw-works brake 63 fully applied, measuring the tension and the rate of change of tension in the deadline 26 by means of sensors 65, 28 respectively, and whilst still continuing drilling operating the brake to maintain a tension in the deadline corresponding to that for which the rate of change of tension is a maximum. Apparatus for measuring the rate of change of tension includes a drum (66 Fig. 4, not shown) rotatable in an anchorage (25), and a member (68) between an arm (67) on the drum and the anchorage and arranged to cause fluidpressure variations in a line (69) in response to the change of tension. The line is connected to a capsule (70) and a vent (75) having a controlled leakage so that a pointer driven by the capsule indicates rate of change of tension. In alternative apparatus Fig. 2 (not shown) the deadline passes between pulleys (33) and a block (34) movable relative to the pulleys. The block moves as a result of change in deadline tension and alters the load on a stack of Piezo-electric discs (34) causing a current proportional to the rate of change of tension to flow in a restistance (45a). The volt drop over the resistance passes to an amplifier (46) and is indicated on a dial (29). A capacitor (45) is provided for damping transient distrubances. The brake may be operated manually following observations of the pointers on dials 27, 29, and the pointers together with a third pointer may sweep a single dial calibrated in bit weight units, the arrangement being that the third pointer indicates the bit weight for optimum penetration. In automatically controlled drilling a timer 89 causes a control 92 to relax the brake until the higher bit weight (deadline tension) is reached. Increase in signal from the sensor 65 detecting the bit weight (deadline tension) causes the control to fully apply the brake when the higher bit weight is reached. The sensor 28 gives a rate of change of bit weight (rate of change of deadline tension) signal which is differentiated in a device 87 and when this signal reaches a maximum the device sends a signal to the control which registers the bit weight at that moment and operates the brake to maintain that weight during drilling. After a given time the timer resets the device 87 and relaxes the brake to allow the cycle to be repeated

Title: Improvements in the manufacture of artificial filaments, ribbons and the like
IPC: D01F2/28
Filed: 1935-07-03
Abstract: Artificial filaments, ribbons and similar textile materials, particularly those of high denier, e.g. of 500 to 5000 or more, are produced by extruding a mass containing an organic derivative of cellulose and a plasticizer or high boiling solvent therefor, and which is free or substantially free from volatile solvent. Products of lower denier may be produced by subjecting the extruded filaments of high denier to a stretching operation, e.g. at 80--100 DEG  C.  A cellulose acetate is usually extruded at a temperature of 100--200 DEG  C. and under a pressure of 1500--2500 lbs. per square inch, either into air or other gaseous medium or into a liquid such as water, benzene, toluene, ether or alcohol. Orifices of the order of 0,01--0,04 inches are used.  The lustre of the products may be increased by subjecting them to treatment with a solvent or swelling agent.  In an example, a plastic mass is prepared by working cellulose acetate, di-(methyl glycol)-phthalate, carbon black, Nigrosine black together with a small proportion of a mixture of acetone, benzene, and alcohol which is removed while working.  The mass is extruded at 110--160 DEG  C. and under a pressure of 1700--2200 lbs. per square inch into air.  In a second example, the extruded mass consists of cellulose acetate and methyl phthalyl ethyl glycollate with or without dyes, pigments, or metal powder, and in a third, cellulose acetate and dimethyl phthalate.  In a fourth example, any of the above plastic masses is extruded through a smaller orifice, i.e. of about 0,012 inch diameter, and the product drawn down to a denier of about 500.  According to the Provisional Specification, the plastic mass may comprise plasticizable materials in general, including polymerized vinyl compounds, poly-hydroxyalcohol-polybasic acid synthetic resins, and other resins.  Specification 366,585 is referred to.

Title: Improvements in or relating to polyamides
IPC: C08J5/00
Filed: 1960-06-02
Abstract: Moulded polyamide bodies having a homogeneous finely crystalline structure and increased surface hardness are produced by cold-drawing the polyamide when in narrow strip or filament form to increased length, melting the drawn polyamide and then forming the moulded body.  Preferably, after being cold-drawn the strips or filaments are comminuted, e.g. in a chopper, before being melted.  It is usually found that increasing the length of the strips or filaments by between 250 and 350% by the cold-drawing is suitable.  Due to the cold-drawing, the crystals originally present in the polyamide are oriented in the drawing direction while, at the same time, large crystalline formations are divided up, i.e. the structure becomes finer, and the growth of crystals is stimulated in amorphous areas, so that a homogeneous crystalline formation is obtained.  Although the mechanical orientation is lost on melting, the fine structure and homogeneity are retained.  German Specifications 1,015,596, 1,052,112 and 1,052,679 are referred to.
