Abstract: 1,158,017. Heptenes. ESSO RESEARCH & ENG. CO. 20 June, 1968 [7 July, 1967], No. 31377/67. Heading C5E. Heptenes are recovered from olefin mixtures comprising C 5-8  olefins by (1) effecting isomerization over an acidic catalyst at 300-500‹ F., and (2) fractionally distilling the isomerizate. The first step, for which H 3 PO 4 /kieselguhr is a suitable catalyst, converts heptenes originally present to isomers having a b.p. enabling easier separation. The fractionation is suitably carried out in two towers, the first having 30-50 trays and the second 40-60 trays, and both having a reflux ratio of 3: 1 to 5:1. The isomerizate is fed to the middle of the first tower, and the resulting bottoms fed to the middle of the second tower, from which heptenes are recovered overhead. The process is particularly applied to treatment of the C 5-7  dehexenizer overheads and/or the C 7-8  deheptenizer bottoms from a UOP polymerization process using propylene/ n-butene/isobutene feed.

Title: Improvements in refrigerating and ice-making apparatus
IPC: F25B17/00
Filed: 1927-11-23
Abstract: 306,879. Mitford, E. R., and Crump. L. Nov. 23, 1927. Refrigerating, absorption and vacuum processes for.-A closed-cycle absorption system working without pumps comprises a vessel a, acting alternately as a heated generator and as a cooled absorber, an absorber b in which a super-saturated solution is formed, and a vessel c in which the gas is evolved from strong solution to produce the cooling effect. Preferably the system is exhausted of air before or after charging with solution. The generator a is initially filled with solution above the open end of a pipe e connecting it with the absorber b, and when heat is applied liquid flows through a non-return valve f in the pipe e to the absorber. As soon as the liquid level falls below the end of the pipe e gas is driven into the absorber and forms a super-saturated solution, and this solution flows through a pipe g and loaded valve i into the refrigerating vessel c, where it is distributed over staggered trays m having apertured baffles n or syphon overflow pipes. At this stage the heat is cut off and the vessel a is cooled, whereupon first gas and then liquid, flow from the refrigerating vessel through a pipe k and non-return valve Z back to the vessel a. When the vessel a is again filled the cycle may recommence. The cooling-water may be diverted automatically from the absorber to the vessel a and the diversion may effect the cutting-off and reestablishment of the supply of heat.

Title: Error detection in digital transmission systems
IPC: H04L1/00
Filed: 1975-07-28
Abstract: 1508915 Data transmission STANDARD TELEPHONES & CABLES Ltd 22 July 1976 [28 July 1975] 31572/75 Heading H4P In an arrangement for detecting errors arising during the transmission of digital signals, particular combinations of successive digits in the signal are modified so that they themselves carry parity checking information, whereby the necessity to add further parity digits to the signal, and thus increase the digit rate, is avoided. As shown, the positive and negative "marks" of a ternary coded digital signal as used in a p.c.m. system are fed to respective shift registers 3, 4 and to an OR gate 5 feeding a parity counter 6 in which the parity of the ternary signals is determined. The contents of registers 3 and 4 are selectively fed in parallel to AND gate 7 together with the output of counter 6 and word alignment pulses. The gate 7 is arranged to detect a particular ternary combination of digits, e.g. + 1, 0, - 1, + 1, 0, - 1 which can occur in the bit stream; upon such detection, the gate 7 delivers an output for one out of the possible two parity values as determined by the counter 6. Thus, the gate 7 delivers a '1' say, if the output of the counter 6 is a '1'. The '1' output of gate 7 is fed over a pulse stretcher 8 to block gates 9 and 10 through which the digital signal passes to a line coupling transformer 13 for transmission, having been read out serially from shift registers 3 and 4, the result being that the detected combination is replaced by a string of zeros - a combination unallowed in the normal bit stream but now indicative of the parity of the preceding digits in the stream At the receiver the "unallowable" combinations are decoded as alternatives to the allowable combination which they had replaced and are recognized as carrying parity checking information. Thus in the receiver the parity information of a sequence of digits is determined, the end of the sequence being signified by the recognition of either the predetermined particular combination or the "unallowed" combination, and an error signal is generated when the said determined parity information differs from the parity information determined at the transmitter as signified by the transmission of either the predetermined or the "unallowed" combination. A suitable circuit arrangement for the receiver is described with reference to Fig. 2 (not shown) and includes a parity counter (22), a shift register (23), gates (24, 25) and a low speed logic (27) for processing the error signal to initiate alarms or calculate the mean error rate etc.

Abstract: 174,242. Amberton, R., and Bray, E. N. Nov. 10, 1920. Automatic circuitbreakers; mechanically tripped and released switches. - In loosehandle electric circuitbreakers of the type described in Specification 144,915, a switch lever 11 is pivoted at 12 to a pair of parallel bars 13 which are in turn pivoted at 14 to a support 15, the links 13 having a cross-pin 20 which co-operates with a projection 19 of the lever 11 to form a rule joint. A toe-piece 23 of the lever 11 rides over a fixed pin 26, and a member 25 pivoted to the frame 15 at 24 has a shoulder 28 on which the pivot pin 12 rests, a spring 21 maintaining the members in the position shown in which the fixed and movable switch contacts 9, 10 are in contact. A releasing-device, such as an electromagnet 18 with a core 32, is arranged so that the core on rising strikes the end 27 of the pivoted arm 25, releasing the pin 12 from the shoulder 28 and allowing the spring 21 to move the lever 11 and links 13 to the full extent allowed by the rule joint between them, thereby breaking the circuit at 9, 10 and bringing the nose 23 of lever 11 into the path of the finger 7 of the loose handle 6. On turning the handle 6 to reclose the circuit, the finger 7 engages the toepiece 23, turning the lever 11 and links 13 solidly around the pivot 14. Shortly before the finger 7 slips out from beneath the toe 23 in its counterclockwise motion, the pivot pin 12 slips on the shoulder 28, and when the toe-piece 23 is released by the finger 7 the spring 21 moves overthe lever 11 with a snap action, bringing the contact 9 into engagement with the fixed contact 10. The electromagnetic releasing-device may be replaced by a mechanical release.

Title: Adaptive logic system
IPC: G06N20/00
Filed: 1968-07-04
Abstract: 1,234,987. Adaptive logic. INTERNATIONAL BUSINESS MACHINES CORP. 4 July, 1968 [17 July, 1967], No. 32072/68. Heading G4R. In an adaptive logic system, adaptive memory units can be conditioned in accordance with their outputs to provide a null output, or (claimed separately) trained using gates provided for negating undesired outputs and encouraging desired outputs respectively. In Fig. 1, a digital input on lines IM1 ... IM15, after receding at 5, is applied to 4 adaptive memory unit blocks (two shown) each of which produces voltages on a respective pair of output lines 1W0, 1W1 ... 8W0, 8W1. The larger of each pair of voltages causes a comparator BDU1 ... BDU8 to light a corresponding one of two lamps 1K0, 1K1 ... 8K0, 8K1, or both lamps are lit if the voltages are equal. During training, a control trigger 7 can be set by a key to activate a mutivibrator 9 to apply conditioning pulses to the adaptive memory units to bring their outputs into agreement with signals from a trainer input 15, with which they are compared at AND gates 11, 13. If trigger 7 is off, AND gates 29, 31 can respond to pulses from a multivibrator 27, switched on by a key, to condition the adaptive memory units to a neutral state relative to the current inputs on lines IM1 ... IM15, viz. a state in which the voltages on the two output lines 1W0, 1W1 ... 8W0, 8W1 are equal. In a modification, the inverters 33, 35 in Fig. 1 are each fed from the other output of the respective comparator BDU1 ... BDU8, and the gates they control, viz. 29, 31, receive the same signals from trainer input 15 as the gates 11, 13, respectively, but lack the input from the off output of trigger 7 and instead have an input from a key-actuated "reward" trigger. Thus actuation of the reward trigger increases the tendency to give the correct output of those adaptive memory unit blocks which are (already) giving the correct output.
