Title: Indicating and/or control apparatus
IPC: F22B35/06
Filed: 1958-04-16
Abstract: 892,953. Electric correspondence control systems. BAILEY METER CO. April 16, 1958 [April 17, 1957], No. 12168/58. Class 40 (1). In an indicating or control system for an industrial plant, an electric signal proportional to a variable dependent on operation of the plant is modified by a non-linear mechanism involving movement, to provide a variable electric reference signal which is compared with an electric signal proportional to a variable, which changes under influences external to the plant and which influences the plant, to produce an error signal for indication or control. In Fig. 1 a direct voltage corresponding to the electrical power supplied by a turbo-generator 4 is derived from a thermal converter 7 of the thermocouple type and applied to a follow-up servomotor 16 which thus adjusts a shaft 17 to a position corresponding to the generator power output. Shaft 17 operates an indicator 21 and controls a movable core transformer 27 through a cam 22 which is so shaped that the signal developed across a potentiometer 32 corresponds to a desired temperature of boiler feedwater corresponding to the particular generator power output. The actual feedwater temperature is measured by a resistance thermometer or thermocouple 9 which controls a movable core transformer 31. The signals corresponding to actual and desired feedwater temperatures are applied, differentially, to control a motor 40 which, in balancing potentiometer 32, indicates any difference and thereby operates a fluid pressure control valve 33 to control the temperature of the feedwater through a system not described. Further signal generators 28, 29 operated by cams 23, 24 on shaft 17 may respectively control the heat supply to and the vacuum associated with the generating unit. Constructional details of the assembly and rack-mounting of the servomotors, cams and signal generators are described.

[Class 2 (iii)] Resinous products comprising a mixed coumarone-indene polymer are obtained from heavy naphtha having a boiling range of 160-190‹ C. by first washing the naphtha with caustic soda to remove materials, e.g. phenols inhibiting thermal polymerization and then distilling the washed material in a still fitted with a fractionating column until a resinous residue is left in the still. The thermal polymerization may be accelerated by the addition of an accelerator, e.g. sulphuric acid or benzoyl peroxide which is added in quantity insufficient of itself to produce the polymerization. 5,000 gallons of heavy naphtha are washed with 500 gallons caustic soda solution and then with 150 gallons of 30 per cent. sulphuric acid. The washed naphtha is distilled in a still fitted with a fractionating column the temperature being raised to 145‹ C. by closed steam the fractionation then proceeding with the addition of open steam and with reflux ratios of 5 : 1 up to total reflux. The distillation required eight days and the yields were-coumarone fraction- 8.2 per cent., indene fraction 25.1 per cent., and coumarone-indene resin-10 per cent. The resin had a m.p. of 110‹C and was amber brown in colour. Reference has been directed by the Comptroller to U.S. A. Specification 1,684,868.

Title: Electrical pulse synchronising systems
Inventor: CLAYDEN DAVID OSWALD
IPC: G11B20/16
Filed: 1953-05-04
Abstract: 767,095. Electric digital-data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 22, 1954 [May 4, 1953], No. 12382/53. Class 106 (1). In apparatus for changing the timing of a given train of pulse signals from being in step with a first clock-pulse train to being in step with a second clock-pulse train having the same mean signal repetition rate as the first train but which may deviate in timing with respect to the first train by up to n signal periods, the given train of pulse signals is delayed by (n + #) signal periods, where #( | # | # n) is the phase difference between the second and first clock pulse trains. In a first embodiment, Fig. 6, signals issuing from a source S (which may be a computer) in synchronism with clock-pulses from a timing device T are transferred to an apparatus A (which may be an auxiliary store) which functions in synchronism with its own clock-pulses, which appear at a terminal 3. This embodiment employs one unit N, comprising two triggers TA, TB, an and gate G, and a short delay D, which is such that it issues a pulse 2 on the receipt of the second of a pair of pulses 1 and 3 and in this embodiment n has the value unity, i.e. the phase difference # between the two clock pulse trains 1 and 3 can be between plus and minus one unit period. Two examples of the operation of the apparatus are illustrated in Figs. 7 and 8 (parts only). In Fig. 7 the second clock pulse train 3, Fig. 7 .(f), is approximately threequarters of a period behind the first clock-pulse train 1, i.e. the phase difference # # is -¥ and n-# has the value 1 ¥. The signals S1 issuing from the source S are then transferred to the apparatus A in the following steps: first the signals are registered in a trigger T1 from where, on the occurrence of a pulse 2, they pass to a trigger T2, and finally, on the occurrence of a clock-pulse 3 they are transferred to the apparatus A. A return path, from the apparatus A to the source S, is provided via triggers T3 and T4. In the second example, Fig. 8, the phase difference # between the second and first clock pulse trains is approximately + ¥, i.e. the first pulse 3 shown at ( f ) corresponds to the second pulse I at (a), and n- # has the value . In a second embodiment (Fig. 9, not shown) three units N are employed and n has the value 3, permitting the two clock pulse trains to differ in phase by up to plus or minus 3 unit periods.

Abstract: 141,535. British Thomson - Houston Co., (General Electric Co.). May 22, 1919. Regulating; indicating position of internal parts; alarms.- Undue deformation or displacement of a turbine rotor causes the rupture of the closed end of a pressure pipe and the consequent operation of a pressure-responsive device. The sealed ends 30 of pipes 29 project from the stator parts towards the rotor. The pipes communicate with a cylinder 21, and on the opposite side of a piston 22, there is a high-pressure eteam connexion 27. Normally, by leakage of the steam past the piston, the pipes 29 are subjected to the pressure obtaining in the pipe 27. If the rotor contacts with an end 30 and disrupts it, the pressure in the pipes 29 falls, and the pressure below the piston 22 raises the piston and, by means of a lever 10, operates an emergency stopping-gear. At the same time. a bar 36 closes the circuit of an alarm bell 33.
