Title: Improvements in or relating to splices for rope ends
IPC: B65H69/06
Filed: 1948-06-03
Abstract: 644,531. Splicing ropes. AMERICAN CHAIN & CABLE CO., Inc. June 3, 1948, No. 15011. Convention date, Feb. 10. [Class 109] A splice for two rope ends comprises a laid inner portion of the same diameter as the rope ends composed partly of strands of one rope end and partly of strands of the other rope end, an outer portion composed of strands lying in the valleys of the inner portion also composed partly of strands of one rope end and partly of strands of the other rope end, together with securing means forcing' the outer strands into the valleys for part of their length. In a preferred method of making the splice, the rope ends C, D, are preliminarily prepared, as shown in. Fig. 1, by applying a ferrule 14 to each rope end, seizing each rope end at 15 at a suitable distance, enlarging alternate strands 16, 18 and 20 from the core and leaving alternate strands 17, 19 and 21 in place around the core, seizing each inner stranded portion at a point midway between the end of the rope and the seizing 15, and finally cutting the core 23 of each rope end at this second seizing. The rope ends are then " married," as shown in Fig. 2, by butting the core ends, and passing strands 17d, 19d and 21d, into the spaces between strands 17c, 19c, and 21c. The seizing being removed, the strands 17, 19 and 21 are laid around the core of the opposite rope end in the grooves resulting from the removal of strands 16, 18 and 20. The strands 16, 18 and 20 in each case are now laid around the inner rope following the valleys thereof, the strands of one rope end alternating with the strands of the other rope end, as shown in Fig. 4. Finally, the ferrules 15 are compressed around the regions including the cut strand ends. The splice may be used with rope ends having an odd number of strands. The ropes C and D may be two separate ropes to be joined or may be the ends of the same rope, particularly when making grommets intended for slings. The splice is intended particularly for wire ropes.

Title: Improved Vehicle Presence Detector System.
IPC: G01V3/10
Filed: 1967-04-03
Abstract: 1,187,145. Vehicle detector. GENERAL PRECISION Inc. 3 April, 1967 [4 April, 1966], No. 15083/67. Heading B7N. [Also in Divisions G4 and H3] A vehicle presence detector for roads or railways comprises an oscillator 27 connected to an inductive loop 12 in proximity to the vehicle so that the presence of the latter reduces the amplitude of oscillation, an amplifier 39-59 receiving the output of the oscillator, a feedback circuit 72-76 having a long time-constant to control the gain of the amplifier to compensate for drift, and an output circuit 78-86 controlled differentially according to the potentials on line 65 (uncontrolled amplifier output) and line 77 (controlled by long-time-constant A.G.C.). The loop 12 is transformer coupled to a Colpitts oscillator 27 of frequency in the range 50-200 kc/s., whose output is amplified at 39 and rectified by diode 54 with capacitor 55 to provide a D.C. input to transistor 58 corresponding to the amplitude of oscillations. A differential amplifier 58, 59 provides a corresponding D.C. level on lead 65 which is stored in capacitor 21 (assuming switch 71 is open). When a vehicle enters the loop, the voltage on line 65 becomes less negative, diode 22 cuts off and the voltage across capacitor 21 does not change. When the vehicle leaves the loop, however, the increase in negative potential on line 65 is stored in capacitor 21. The discharge path of the capacitor is made long by the Darlington transistors 72-74 and resistor 75 to hold a signal if the vehicle remains stationary in the loop. This signal is applied through transistor 76 and resistor 51 as A.G.C. to the amplifying transistor 39 by connecting the diode 42 and transistor 41 in parallel with the emitter resistor 45. Arrival of a vehicle at the loop produces a sudden change in the signal level at transistor 39 which acts through capacitor 47. The voltage levels on lines 65 and 77 will then be different, and a differential amplifier 78, 79 will produce an output to operate Schmitt trigger 85, 86 and cause a relay 26 to change over the output connections 93. This condition will remain until the vehicle leaves the loop or the capacitor 21 becomes discharged, when the levels at 65 and 77 become equalized. If the vehicles are to be counted, or for another reason the holding of the signal is not required. switch 71 is closed and the capacitor 21 changes its voltage only transiently.

Title: Improvements in or relating to substituted benz (cd) indolines
Filed: 1953-06-10
Abstract: The invention comprises compounds of the formula <FORM:0747264/IV(a)/1> wherein R represents an aliphatic acyl, or a monocyclic aroyl radical, R1 represents a cyano, carboxy, carboxyalkyl or N-methylthioamide radical, and R2 represents hydrogen or a cyano radical when R1 is a carboxy radical, and R2 represents a cyano radical when R1 is other than a carboxy group.  The novel compounds may be prepared by reacting N-acyl-5-formylbenz[cd]indoline(I) with an appropriate compound containing an active methylene group.  In examples: (1) a -cyano-b -(5-N-benzoylbenz [cd]indolinyl) acrylic acid is obtained by reacting cyanoacetic acid with (I); (2) b -(5-N-benzoylbenz[cd]indolinyl) acrylic acid is obtained by heating (I) with malonic acid; (3) t-butyl-a -cyano-b -(5-N-benzoyl benz[cd]indolinyl) acrylate is obtained by refluxing (I) with t.-butyl-cyanoacetate; (4) ethyl-a -cyano-p-(5-N-benzoylbenz[cd] indolinyl) acrylate is likewise obtained using ethylcyanoacetate; (5) N-methyl - a  - cyano - b  - (5 - N - benzoylbenz[cd]indolinyl) thioacrylamide is obtained by heating (I) with cyanothioacetomethylamide; (6) a -cyano - b  - (5 - N - acetylbenz[cd]indolinyl) acrylic acid is obtained by reacting N-acetyl-5-formylbenz[cd]indoline with cyanoacetic acid; (7) a  - cyano - b  - (5 - N - benzoylbenz[cd]indolinyl) acrylonitrile is obtained by heating (I) with malononitrile.  The N-acyl-5-formyl-benz[cd]indolines are prepared from indole-3-propionic acid as described in Specification 726,876. Cyanoacetomethylamide is obtained by reacting methylamine with ethylcyanoacetate and is converted into cyanothioacetomethylamide by refluxing with phosphorus pentasulphide in xylene.  The novel compounds are intermediates in the synthesis of lysergic acid.  Thus reduction of the cyano group of alkyl a -cyano-b -(5-N-acylbenz[cd]indolinyl) acrylates or a -cyano-b -(5-N-acylbenz[cd]indolinyl) acrylonitriles followed by cyclization and hydrolysis yields nor-lysergic acid derivatives which on methylation and removal of the acyl group gives lysergic acid.  N - Methyl - a  - cyano - b  - (5 - N - acylbenz[cd]indolinyl) thioacrylamides may be desulphurized with Raney nickel and the resulting secondary amines hydrolysed and cyclized to lysergic acid.
