Title: Improvements in or relating to electrical signalling systems
Inventor: ALDRIDGE EDWARD ERNEST
IPC: H04Q11/04
Filed: 1962-05-16
Abstract: 997,835. Multiplex pulse code signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 8, 1963 [May 16, 1962], No. 18899/62. Addition to 946,254. Heading H4L. The system of the parent Specification for interconnecting pulse communication systems subject to variations in timing in which two stores are used alternatively and provided with means for altering the storage sequence in the event of phase conflict is adapted to enable the combination of a number of low-speed pulse communication systems into a single high-speed system. Fig. 2 shows the equipment associated with one channel CH1, CH2 ... CHm indicating the remaining low-speed channels. It is assumed that the transmission speed of the incoming channels is a bits/second so that the transmission rate for n channels over the high-speed channels will be na bits/second. A clock LC for channel CH1 is operated by timing pulses on line DS and a clock HC for the high-speed system is operated by timing pulses on line SS. The capacity of each store M, M<SP>1</SP> &c., is c bits and the clock LC produces an output pulse every c timing pulses which controls a gate GA producing alternate outputs A, A<SP>1</SP>. Gates GB, GC, GD are linked to change over in synchronism with gate GA so that when gates GA, GD are providing outputs on A and D respectively, the gate GB is providing an output on B<SP>1</SP> and input C<SP>1</SP> is operative for gate GC, and vice versa. Assuming that gate GA is supplying an output on A, the incoming data signals over lead D are supplied to the store M, writing-in being controlled by timing pulses via gate GD. The clock HC also provides an output every C timing pulses but in its full cycle produces n outputs which open in turn gates GF, GG, GH &c., corresponding respectively to the low speed systems, each of these gates then closing the preceding one. When gate GF is opened high-speed timing pulses at a pulse repetition frequency na are supplied via output B<SP>1</SP> of gate GB to control the reading out of data stored in the store M<SP>1</SP> via input C<SP>1</SP> of gate GC and output terminal HS. The functions of reading and writing in the memories M, M<SP>l</SP> are reversed each time an out- - put is obtained from the clock LC and gates GA, GB, GC, GD change-over. High-speed timing pulses also pass via the gate GF to a gate GE and if the clock LC should be in the last but one position at this time a second pulse is supplied to the gate GE so that it provides an output signal RS to reset the clock LC. To minimize the error the resetting point is about halfway, C i.e. the clock is set back - bits, so that one 2 C block of - bits, may be repeated or omitted. 2

Title: Improvements in or relating to cross-counterflow heat exchangers
Inventor: BECKER RUDOLF
IPC: F28D7/16
Filed: 1966-04-30
Abstract: 1,136,292. Tubular heat exchangers. LINDE A.G. 30 April, 1966 [30 April, 1965], No. 19087/66. Heading F4S. A cross-counterflow heat-exchanger comprises, within an outer casing, not shown, a tube assembly formed from a number of coaxial sections separated from one another by metal diaphragms M and each consisting of a number of coaxial tube layers, e.g. 1-5, arranged in a staggered fashion and composed of a plurality of helically coiled tubes, each section being such that the tube length of its outermost layer does not exceed by more than 10-15% that of its innermost layer. As the distance, from the exchanger axis, of a section increases so the number of helically coiled tubes, in a layer of that section, is increased and the number of turns made by these tubes is decreased so as to maintain a mean tube length and overall axial height of the exchanger equal from section to section, this also being partly effected by varying the centre-to-centre spacing of adjacent tubes.

Title: Neutron logging reliability techniques and apparatus
IPC: G01V5/10
Filed: 1974-05-01
Abstract: 1470568 Borehole logging SCHLUMBERGER Ltd 1 May 1974 [1 May 1973] 19104/74 Heading G1A The invention relates to verifying the accuracy of borehole logging measurements obtained by irradiating the formation with pulsed neutrons and monitoring, thermal, neutron populations in the formation by means of two detectors spaced at different distances along the logging tool from the neutron source. The method used involves obtaining a value of a thermal neutron absorption characteristic e.g. the decay time # N  for the "rear" detector and using this with signals derived from the "far" detector, to obtain a ratio representative of or from which is derivable the quantity # N /# F ; this ratio should equal unity for valid measurements and deviation therefrom indicates the effects of neutron diffusion &c. on measurement accuracy. The logging tool comprises sodium iodide scintillation crystals coupled to photo-multiplier, monitoring γ-radiation from thermal neutron capture or alternatively, thermal neutron sensitive detectors e.g. He-3 filled proportional counters. The neutron source 18 is arranged to produce discrete pulses of 14 Mev high energy neutrons of one decay time (#) duration, at intervals of 12-15#. The neutron population is sampled in these intervals at 2# after the irradiation pulse has ended for a duration of #: at 3# afterwards for 2# duration; and at 11# afterwards for 3# duration. The first and second sample periods counts; N 1 , F 1  and N 2 , F 2 , represent neutron population counts and the third N3, F 3 , represent background gamma counts to be subtracted therefrom. In the arrangement of Fig. 1, # N  and # F  are calculated by loops 26, 28 which operate by adjustment of the sample interval times and durations until a predetermined value for ratios N 1 /N 2  and F 1 /F 2  are obtained, when the first sample interval duration will equal # N , # F  respectively. Values of # N , or # N /# F  are recorded on tape and visually. In the embodiment of Fig. 2 (not shown), only a # N  loop is provided, the # F  loop being replaced by a far signal gating circuit controlled by the # N  loop. The function used to test accuracy in this case is the ratio F 1 /F 2  which is linearily related to # N /# F . # N  and the ratio # N /# F  obtained from F 1 /F 2  by means of a potentiometer, are recorded. Alternatively, they are supplied to a circuit, Fig. 4 (not shown) which averages # N /# F  and under it by # N  to obtain # F  also. In a further alternative, Fig. 5 (not shown) # N /# F  is compared with a reference value to select whether # N  or # F  is recorded as the more accurate. In a further embodiment, a computer is used to solve an exponential equation relating the far detector counting rate ratio and # N , Fig. 6 (not shown).
