Abstract: 1,182,250. Rotary cylinder engines; lubricating; cooling cylinders. VINCENT ROTARY ENGINES Ltd. Aug. 15, 1967 [Aug. 30, 1966], No. 38576/66. Heading F1B. The rotor 20 of a rotary cylinder engine is sealed by a sealing ring 37 engaging the face 56 of the stationary casing 32, the sealing face of the ring being supplied with sealing liquid through passages 63, 62, 60. Additional passages 66, 67, in the part of the rotor 20 adjacent the ring 37 are arranged so that the suction set up by shear drag in the film of sealing liquid prevents sealing liquid flowing through passages 53, 39, to the combustion space. The sealing liquid is lubricating oil from the bearings which collects under pressure in passage 63 due to centrifugal action. Spring-loaded plungers 58 urge the ring 37 against the face 56. The rotor 70 carries sealing vanes 72 which rest on followers 74, Fig. 4, having grooves 77 through which excess sealing liquid is removed. The rotor 70 is supported on a bush 23 on a stationary hollow shaft 24 and a ring gear 44 on the rotating hub member 22b drives the crank-shaft 10 in the opposite direction of the rotor through planetary gears engaging a run wheel 43. The hub 22a of the rotor has a power-take-off extension 27 having teeth 30 driving the oil pump and distributer. Openings 8, 8a for cooling air are formed in the stationary casing and the rotor and air impeller blades 41 are carried by the rotor. The cross-section of the cylinder intake port is adjusted according to speed by a member 50 which is moved transversely across the port.

Title: A method of recovering heat in a chemical process
IPC: C01B3/16
Filed: 1956-12-21
Abstract: <PICT:0850282/III/1> In a chemical process involving a reaction in a vessel, heat is recovered by heating gaseous reactants at low pressure by a liquid heat exchange medium in a heat exchanger, compressing and then reacting the gaseous reactants, cooling the reaction products from the vessel at a pressure higher than that of the reactants by the liquid medium in another heat exchanger, and passing the so heated medium to the first exchanger.  The heat exchange may be direct with the vapour of the medium being a reactant or catalyst.  In reacting carbon monoxide and steam under pressure to produce carbon dioxide and hydrogen, water gas is passed at 8 under 9 atms. into heat exchange saturator 1 countercurrent to hot water. The saturated gas is compressed in 4 to 12.5 atms., and passes, together if necessary, with steam from 9A, through indirect heat exchanger 5 to reactor 6, which is supplied with cooling water at 12.  The products from 9C pass through heat exchangers 5, 7, to heat exchanger column 2 where they flow countercurrent to fresh water entering at 10 and water pumped through 3, 31 from column 1.  The water from 2 is returned through heat exchanger 7 to column 1.

Title: Improvements in or relating to character recognition apparatus
IPC: G06V10/24
Filed: 1962-10-17
Abstract: 1,024,743. Automatic character reading. CHARACTER RECOGNITION CORPORATION. Oct. 17, 1962 [Oct. 17, 1961], No. 39372/62. Heading G4R. In a character recognition apparatus the characters are scanned along parallel lines by a row of photo-cells, the outputs being sampled in turn repeatedly to obtain a succession of series of binary signals representing the character. The character, Fig. 4 is scanned in eight lines X 1 -X 8  and each is sampled ten times by AND gates 21-28, Fig. 2 (not shown) enabled in turn by distributed timing pulses from ring counter 12. The outputs are applied through OR gate 29 to terminal 40. A flip-flop 14 is set and reset in alternate cycles of the counter and gates 21-28 are opened only on the even numbered cycles so that the first, third and other odd cycles are ignored. Ignoring the first column prevents errors arising from ragged edges of the leading parts of the character. The counter is started by the first black to appear in any photo-cell and is automatically reset at the end of a character by the detection of two or three blank cycles. The signal at terminal 40 consists of a series of serial pulse trains which are applied through direct and inverting amplifiers 221, 222, Fig. 3 (not shown), for comparison with stored patterns, one of each possible character. These consist of a matrix of gates each consisting of three diodes, one in a section relating to the photo-cell X 1- X 8,  Fig. 4, one in a section relating to the sampling cycle Y 1 -Y 12  and one being enabled or not according to whether the corresponding point is black or white. The X and Y terminals are selected by ring counters 210, 216 which between them select the points on the character in turn. The diodes are arranged so that a non-match gives an output, i.e. a white signal in an area which should be black and vice-versa. The cross-hatched areas of the character, Fig. 4, are indefinite and have no connections. A string of pulses are produced, one for each non- match between the signal train and the pattern set up. These pulses are counted in a condenser or digital counter and the least is representative of the best match to identify the character. The counters start at the first black in the second cycle so that the signal pattern is registered with the gating array irrespective of the vertical registry of the character. In another form the pulse trains representing alternate characters are read alternately into two shift registers. While the second is being read in the first is being read out synchronously with reference trains from a magnetic drum store. The character train is compared with each reference train by an AND-NOT gate, mis-matches giving an output which is passed to a counter as before.

Abstract: 1,007,933. Bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 9, 1961 [Nov. 30, 1960], No. 40125/61. Heading H3B. A bi-stable circuit comprises a non-linear capacitance diode 11 negatively biased through a resistive load 22 and driven by a source 16 of microwave frequency. The diode is equivalent to a parallel arrangement of a non- linear capacitor and a non-linear resistor and in one stable state an inductive element 14 and the capacitor of the diode are in resonance at the frequency of the source 16. The inductive element 14 and the diode may form either a series resonant circuit, as shown, or a parallel resonant circuit. In Fig. 3, curve a represents the voltage-current characteristic of the diode as viewed from terminal X when there is no high frequency drive from source 16. Curves b, c, d represent the characteristics of the diode with increasing values of the driving current. The direct current load line of the device is represented by e. When using the value of driving current represented by curve c, the two stable states are represented by points f, g, the corresponding potentials at point x then being -Vc, -Vr. There is resonance at g but not at f. The amplitudes of the microwave voltages in the two states f, g are shown at 13, 15, Fig. 4. The corresponding direct current voltages are shown at 19, 17. The device may be switched between states by applying potential at X or by changing the amplitude of the high-frequency supplied. In a modification, two oppositely biased diodes 40, 48 coupled with inductive elements 38, 46 are driven by a common source 16. Branches 31, 34 act as the loads across diodes 40, 48. In Fig. 7, the characteristics of the two diodes are represented by 40<SP>1</SP>, 48<SP>1</SP> and the two stable states are represented by points m, n. Logical devices.-The bi-stable circuit of Fig. 6 may be arranged to switch in response to any two of three possible direct current signals. Circuits A, B, C, Fig. 8, each have three input leads and three output leads. The input leads of A are 1b, 2a, 3b and the output leads are 1c, 2c, 3c. The microwave frequency source for the three circuits A, B, C transmit pulsed trains, as shown in Fig. 9, so that information is transferred in the direction A, B, C. In Fig. 10, high-frequency signals may be applied to leads 18d, 18e, 18f. If the circuit is arranged to switch in response to a signal on any one of leads 18d, 18e, 18f, it acts as an OR circuit. If the circuit responds only to two or more signals it acts as an AND circuit. Specification 793,799 is referred to.
