Patent GB-1054866-A (GB)
IPC: C10K3/04
Abstract: 1,054,866. Purifying gases. METALLGESELLSCHAFT A.G. and STEINKOHLENGAS A.G. Sept. 16, 1964 [Sept. 18, 1963], No. 37895/64. Heading C5E. In a process in which the CO content of a fuel gas is reduced by catalytic shift conversion at 4, the crude gas is cooled at 2 and prepurified at 3 by circulating condensate obtained from the gas, and the converted gas is cooled in a plurality of stages, all the condensate from the first stage 6 being delivered to the prepurifying circuit, from which excess condensate is removed. Gas from a generator 1, made e.g. by the pressure gasification of coal with oxygen, and steam and/or carbon dioxide, is cooled and saturated with water vapour at 2, and traverses a waste heat boiler 3 from the sump of which condensate is circulated via the cooler 2, a valve 12 (to waste) acting under the control of the liquid level in the sump. Condensate from the stage 6 is passed, if desired, via a heat exchanger 5 for the converted gas, to a washer 7, and tar oil, e.g. 4% by weight of recycled condensate, may be added at 23. Conversion is at 380‹ to 460‹ C. over a Co/Mo catalyst. In a modification, Fig. 2 (not shown), the waste heat boiler 3 is omitted, the cooler 7 surmounts the cooler 2 through which condensate is circulated, and condensate from the cooler 6 is passed to the cooler 7, as before. The cooler 2 is thus of counter-current type, but may be concurrent (as in Fig. I) by arranging the coolers 2, 7 side by side. In both embodiments, condensate from the later postconversion cooling stages is preferably delivered to the first stage.

Abstract: 1,057,813. Telegraphy. TELETYPE CORPORATION. Sept. 26, 1963 [Oct. 17, 1962], No. 37884/63. Heading H4P. In a perforated tape reader the sensing pins are brought to the tape during each reading cycle by an electro-magnet, means such as a spring act during the last part of the movement of the sensing pins to de-celerate them and to store energy during the de-celeration. The stored energy is used to speed the return of the pins to the retracted position. Tape sensing.-The electromagnet 23 pulls up armature 36 so that arm 40 moves clockwise, Fig. 2. This action moves sensing pins 75 upwards. Bail 51 also moves upwards, over section 57, and, towards the end of the movement of the armature to the polepieces, compresses spring 62. This de-celerates the components, and the spring stores excess energy by compression. At the end of the reading cycle the armature is released so that the spring can accelerate the pins away from the tape. A resilient washer 53 takes the force of the returning bail 51. Those of the pins which sense holes in the tape move upwards sufficiently far for contact springs 85 to make with a fixed contact (not shown), whereby a parallel output is obtained. Tape feed.-As the armature 36 pulls up, feed pawl 100 moves upwards and to the right, whereby blocking pawl 131 and crank 139 move clockwise out of engagement with wheel 102. Pawl 100 engages with the next ratchet tooth and, when the armature releases, the downward movement of the pawl advances the tape. Pawl 131 and crank 139 re-engage wheel 102, the pawl preventing over-run and a detent on the crank, being spring-urged against the wheel, ensuring centring of the wheel's rotation. Tight tape detection.-An arcuate bail (not shown) is concentric with feed wheel 102, the tape passing under the bail. If the tape becomes tight the bail rocks a lever to open a spring contact in the electromagnet circuit. Tape-out detection.-A finger 191, Fig. 8 (not shown), spring-urged upwardly, is depressed when tape is present. If the tape is absent arm 181 moves upwards, opening a spring contact in the electromagnet circuit. Control arm 144.-This arm has Run, Stop and Free positions. In the first a contact is closed which completes a circuit causing reading and stepping of the tape. In the Stop position this circuit is broken, as also it is in the Free position. In this latter position camming surface 147 rotates blocking pawl 131 clockwise so that it, the feed pawl 100, and the crank 139 are all dis-engaged from the feed wheel 102, Fig. 7 (not shown). In addition, the finger 191, Fig. 8 (not shown), is brought to the position shown in broken line, so the tape can now be drawn freely through the reader.

Abstract: 1,227,320. Combined waste and overflow devices. ALLIED IRONFOUNDERS Ltd. 3 July, 1968 [21 July, 1967], No. 33570/67. Heading A4N. A waste pipe system extends from a drainage outlet in a receptacle, and comprises a tube, one end of which communicates with the drainage outlet, the other end of the tube lying below the outlet, the uppermost part of the tube being at a level higher than the normal liquid level in the receptacle but lower than the overflow level. In a preferred embodiment shown in Fig. 1 a bath 1 with ra drainage outlet 2 communicates via a short pipe 3 with a tube 4, one end of which is connected to a liquid trap 5 leading to an outlet 6. The uppermost part 7 of the tube 4 lies below the overflow level 8 but above the normal liquid level. If further liquid enters the bath 1, so that the tube 4 is completely filled, liquid will siphon away through the outlet 6 and the bath will not overflow. To empty the bath further liquid may be allowed to flow into the bath, thus filling the tube 4 and allowing the liquid to siphon off through 6. In an alternative arrangement, Fig. 2 (not shown), the tube (4) is movable and when in the lowered position liquid will drain away by gravity through the outlet (6) and thus empty the bath. Movement of the tube may be achieved by its connection to an operating lever.

Abstract: 1,228,052. Digital transmission systems. ING C. OLIVETTI & C S.p.A. 19 Sept., 1968 [3 Oct., 1967], No. 44688/68. Heading H4P. [Also in Division G4] In a system comprising a central computer and a number of teleprinter terminals, each terminal has a control unit which includes means for detecting control signals transmitted from the computer and for checking the parity of received signals, the code bars of the terminal's transmitter being set by the control unit to cause appropriate control signals to be transmitted to the computer. When the computer is ready to receive from a particular terminal it transmits the appropriate address and control signals which cause the terminal to return a control signal indicating its address and whether or not it wishes to send a message. In the latter instance a block of characters follows, terminated by an "end of block" signal. The computer checks the signals and sends an acknowledgment if it detected no fault and a request for repetition of the block if it received no signal or detected a fault. When the terminal receives the acknowledgment it returns a control signal indicating whether or not it has further characters to transmit. If it has, the computer repeats the complete cycle. If an expected reply to a control signal is either received mutilated or is not received within a certain time an appropriate control signal is transmitted. When the computer has a message for a particular terminal the dialogue is substantially similar to that described above, the computer, not the terminal, sending the block of characters.

Air enters the carburetter body at 12 and flows past an air-valve slide 17 and fuel supply orifice 21, the amount of air being controlled by a valve 14. A profiled needle 22 controls the fuel supply. A passage 23 formed along the body, is connected to the induction passage by an opening 25, which is adjacent the edge of the valve 14 when in the idling position. The opening may be either a circumferential slot or a row of separate holes preferably subtending an angle of not more than 6 degrees at the axis of the induction passage. The other end of the passage 23 turns through a right-angle and opens into an external flat surface 29 on the body 10. A passage 31 leading from the air inlet passage 12 also opens into the surface 29. A flow restricting unit 32 secured to the surface 29 has a first passage 33 which connects with the passage 31, a second passage 37 which connects with the passage 23 and a third passage 34 which is joined to the first passage 33 by a cross-passage 35. A further cross-passage 36 connects the first, second and third passages. Flow from the passage 33 to cross-passage 35 is controlled by a plug 38 having bores 41, 42 and this is augmented by the flow pasta tapered section 45 of an adjustable screwed plug 43. The flow through the bores 41, 42 is further controlled by the tapered portion 46 of the plug 43 which cooperates with the passage 36. In a modification Fig.4 (not shown) the outlet opening 25 is moved to a position downstream of the throttle valve and a rotary valve is provided in the passage 23. This valve is linked to the throttle valve, so that as the throttle valve moves away from the idling position, the rotary valve moves to the closed position. Alternatively, a solenoid-operated valve may be provided in the passage 23, the valve being controlled by an electrical switch operated by the throttle linkage to move the valve to the closed position as the throttle moves away from the idling position. The air flow is shut off during a movement of the throttle valve such that the total air flow through the carburetter does not change by more than 1 lb/min.

Abstract: 1301337 Digital transmission systems; amplitude and phase modulation INTERNATIONAL COMMUNICATIONS CORP 13 Oct 1970 [18 Nov 1969] 48533/70 Heading H4P In a transmission system data is continuously grouped into multi bit words of equal length divided into multi bit sub groups each combination of which corresponds to different relative phase differences in a carrier signal during successive modulating periods, and the remaining bits within each word vary the amplitude of the carrier such that each possible combination of remaining bits corresponds to a determined amplitude level. Serial binary data also synchronizing signals from clock 10 are fed to a scrambler 12 feeding into an encoder 13 which sections the data into three bit groups of which the first two bits determine the relative phase and the third determines the amplitude. Pulses are developed from the three-bit combinations, as shown in the table, which are fed to a ring counter 14 which enables one of AND gates 17-20 also receiving phase displaced inputs from network 16 supplied from an h.f. source 15. Output from gates 17-20 are commoned into an amplitude modulator 21 receiving each of the third bits from encoder 13 so that a "1" determines a one amplitude level and a "0" a second level as set out for example in Fig. 2A (not shown). With groups of three bits all eight combinations may be uniquely defined by four phase differences in conjunction with two amplitude levels. The signals are passed to line through a filter and translating circuit 22 which converts the high frequency modulated signal to low frequency wherein the phase and amplitude relationships are unchanged by the frequency transposition, through a narrow pass filter compensating for amplitude and delay characteristics of the line, and an equalization circuit which may be as described in Specification 709,608. A feature of the receiver, Fig. 3 (not shown), which comprises a phase detector (30), amplitude detector (32) and clock extraction circuit (31) feeding into a decoder (33) and descrambler (34) is the automatic gain circuit (40) operating by variable negative feedback on amplifier (26) are controlled by a selector circuit so that the amplifier output is adjusted according to whether the two discrete amplitude levels vary from their prescribed levels, as illustrated in Fig. 5 (not shown), a transistor switching circuit for which is described in connection with Fig. 4 (not shown).
