The store may be employed as part of a control unit for controlling a number of devices according to a predetermined program retained in the store. Input and output to the control unit may be via electromechanical relays, which are arranged to maintain themselves in the operated condition when their energizing signals are removed (Fig. 3, not shown). The data (program steps) removed from the store are fed to horizontal lines of a diode logic matrix (Fig. 2, not shown), timing signals being fed to a first set of vertical lines thereof and control signals being obtained from a second set of vertical lines thereof.

Title: Rotary piston engine
IPC: F01C1/22
Filed: 1972-11-30
Abstract: 1453700 Rotary-piston IC engines BRITISH LEYLAND UK Ltd 20 Feb 1974 55450/72 Heading F1F A throttle valve 16 is linearly displaceable by a lever 24 and associated throttle cable within an inlet duct 14 to vary the area of an annulus defined between the valve and duct and thereby control an inlet port 13 of a combustion chamber in a rotarypiston I.C. engine of the internally meshing n and n + 1 type. A butterfly valve 26 is mounted in the duct 14 upstream of valve 16 and has a spindle 27 upon which is mounted a lever 28 coupled to a lever 30 and a cam (40) Fig. 3 (not shown). The cam (40) co-operates with a lever system (not shown) to displace a plunger 33 controlling a bypass bore 31 linked to duct 14 by a milled slot 32. Upon start of the engine, a choke lever rotates spindle 27 and the cam (40) whereby the lever system withdraws the plunger 33 to permit induction of a large amount of air fuel mixture. Thereafter operation of the throttle cable (not shown) causes lever 24 to withdraw valve 16 from its seating 15, the throttling effect of the valve 16 serving to accelerate the fuel mixture and thereby improve atomization and increase turbulence with a consequent reduction of exhaust emission and improvement in fuel consumption. The valve 16 and 26 are moved by the throttle cable and levers 24, 30 so that under idle and partially loaded conditions valve 16 has greater effect than valve 26 but as the load increases towards full throttle and valve 16 becomes fully opened valve 26 has the greater effect. In an alternative embodiment butterfly valve 26 is dispersed with.

The filter output is not affected by phase differences between its input and the derived clock frequency. The generation, superimposition and subsequent extraction of the signalling frequency is described in referenced Swiss patents for ripple control. In the receiver shown, main frequency is attenuated and the signalling frequency extracted in RC filter 35, A-D converted 40 then fed through the filter 43 and D-A converter 48 or digital comparator. The clock frequency is derived from a PLL integrated circuit 37 and controls the transfer function of the filter 43, which may be of band-pass type. Alternatively a computer alters a digital signalling input according to the clock frequency and taking into account past and present input and output values. The sampling filter may be composed of subtractors and integrators with feedback to produce a transfer function S/(a 2  + a,S + S<SP>2</SP>). The integrators are outlined (Fig. 8, not shown).

In the embodiment of Fig. 1 (a triple-ramp converter), an analog input signal 1 is applied to the inverting input of an integrating amplifier 11 to charge a capacitor 14 during an interval determined by a clock 94 and the capacity of a counter 106. The polarity of the analog signal is tested by a comparator having inputs 12, 42 and an output 75, the result being indicated by the state of a bistable 83. Capacitor 14 is then discharged by the successive application of V1 and an auxiliary reference potential V2 : both are negative, and V1=10V2. V1 is applied to the inverting or non-inverting input of amplifier 11 according as the analog signal polarity is positive or negative, while pulses from clock 94 are applied to the tens-increment input 105 of counter 106; Vz is then applied to the opposite input while clock pulses are applied to the unitdecrement input 107. Finally the count in 106 is transferred to a staticiser 111 and the polarity is displayed at 113. Means 5, 43-47 and 65-66 are provided to impress on circuit point 3 any voltage change at point 42 so as to avoid unwanted potentials developing between the inputs to amplifier 11. A feedback loop 51-62 is provided for drift correction. In the embodiment of Fig. 3 (not shown), V1 and V2 are always applied to the inverting input and the analog signal is applied to the inverting or non-inverting input according to its polarity: when charged, capacitor 14 is in this case always of the same polarity.

A process for making lower boiling hydrocarbons from residual oils comprises contacting the residual with a deasphalting solvent, subjecting the deasphalted oil to hydrogenative cracking and the asphaltic compounds to partial combustion with an O 2 -containing gas to obtain H2 which provides some at least of the H 2  for the cracking step and optionally for an earlier refining step for the deasphalted oil. If oil boiling higher than gasoline is obtained from the cracking, it may be passed to the partial combustion step, acting, e.g. as diluent for asphaltenes from the deasphalting step. Whatever use the H 2  is put to, it should be first purified, and any soot thus obtained may be pellitized with oil and returned to the partial combustion step, to which steam and/or CO 2  may be delivered.

Abstract: 1276707 Automatic exchange systems PLESSEY CO Ltd 30 Nov 1970 [24 Dec. 1969] 62827/69 Heading H4K In a telephone exchange abbreviated dialling codes are translated into full directory numbers which are entered into a store and applied digit by digit to a register, for each digit registered the contents are tested for a complete routing   code and a counter is incremented, when a routing code is recognized an appropriate junctor is selected and digits still in the store are read out in parallel to a sender associated with the selected junctor, the counter masking the transmission of digits applied to the register prior to recognition of the routing code. As described, routing codes may have up to four digits and the counter is a three-stage counter operating a relay for each stage. The relays operate contacts in the outlet paths of the store. The translations may be in dial pulse or 2 out of 5 code form. As shown, when a call is originated from a subscriber's line 1 a path is set up to an assigned supervisory device 3 via a network 2. The subscriber commences to dial digits into a register 4 and for each digit a router 5 attempts to translate into a routing code. During each attempt in which a routing code is not recognized a counter 15 is incremented by one. During a normal call the router recognizes a code after say four digits and generates a signal RF which selects an appropriate junctor 6 and a sender 7. A path 8, 9 is set up between the supervisory set 3 and junctor 6 and subsequently dialled digits are transmitted over this path and the outgoing junctor. If the router 5 recognizes the first group of digits as a short code, this short code SC is forwarded to a gating array 11 which also receives at 10 the identity of the calling subscriber. A gate responds reading out the corresponding directory number from a location in a short code translation store 12 into a buffer store 13. The directory number is transmitted one digit at a time to a register 4. When a routing code is detected a junctor 6 and a sender 7 are selected and a gating arrangement 14 operated under control of the counter to transmit the digits in store 13 but not already sent to register 4 in parallel to the sender 7, and the translator 12 is released.
