Patent GB-1359990-A (GB)
Title: Coders
IPC: H03M1/00
Filed: 1970-12-19
Abstract: 1359990 Analogue/digital converter MARCONI CO Ltd 26 Oct 1971 [19 Dec 1970] 60407/70 Heading G4H In an analogue/digital converter of the type in which a counter is incremented by pulses from an oscillator until the potential on a capacitor charged by a current derived from constant current generator means is equal to the amplitude of the unknown analogue voltage, the charging current is controlled by the instantaneous count in the counter.  In the embodiment described (Fig. 1) the unknown analogue signal is sampled and stored on capacitor C2 by operation of switch. Counter 2 controls via NAND gates 53, 54, 45, 57 constant current generators 59-61 providing currents of values 3R/128, 12R/128, 48R/128. A fourth generator providing current of value I/128 is permanently on. Initially the counter receives pulses via a gate 11 until the third most significant bit is "1" when a switch 52 is operated to pass the counter via a divider 51 (dividing by 2). When the second most significant bit is "1" the gate 54 is enabled to turn on generator 59 and simultaneously the divider 51 is switched out until the third most significant bit again becomes "1". Similarly when the most significant bit is "1" generator 60 is turned on and the divider is switched out of circuit. When both the first and second most significant bits are "1" the third generator 61 is enabled. After each measurement the capacitor C1 is discharged via switch 7 and the counter is reset.  The apparatus may be used for p.c.m. coding of speech signals.

Title: Exhaus gas purifying device for an internal combustion engine
IPC: F01N1/00
Filed: 1971-12-30
Abstract: 1364090 Treating exhaust gas TOYO KOGYO CO Ltd 30 Dec 1971 [30 Dec 1970] 60848/71 Heading F1B An I. C. engine comprises an exhaust gas purifying reactor, means for detecting warm-up of the engine and/or the reactor and an engine speed control means for maintaining the engine speed above 2500 r.p.m., the control means being responsive to the detecting means so that upon initial starting of the engine from cold the engine speed is held above 2500 r.p.m. until the engine and/or reactor have warmed up. An I. C. engine 1 is connected to a reactor 2 which is supplied with secondary air for oxidizing unburned hydrocarbons and carbon monoxide. The reactor may contain a catalyst and is connected to a further catalytic reactor by a pipe 4 and by a further pipe 6 to a silencer 5. In parallel with the tail pipe 7 is a further silencer 8, through which the gas is diverted by a valve 47 when the engine is cold. A gear lever 18 is connected to a neutral switch 19 through a holding device H so that the switch 19 closes only when the gear is in neutral and the starter motor switch has been operated. If the engine stops the switch 19 opens and remains open until the starter switch is operated. A thermosensor 20 energizes a solenoid 21 when the engine has warmed up and opens a normally-closed switch 22. A further switch 24 is connected to a diaphragm 25 which when the engine has started is affected by the suction in the inlet pipe 11 and duct 23 and closes the switch 24. The three switches 19, 22 and 24 are in series in an electrical head supplying power to a solenoidoperated valve 28, which when energized opens the valve-member 30 and allows the vacuum in pipe 11 to act on diaphragms 36 and 37 and move the throttle valve 12 and choke valve 15 to a partly open position, determined by adjustable stop screws 42 and 43. The engine then runs at a speed (e.g. 2500 r.p.m.) which is higher than the speed at which the engine runs due to the action of the choke alone. When the engine reaches a predetermined temperature the thermosensor 20 opens the switch 22 and the valve-member 30 returns to the closed position. Similarly, if the gear lever is moved out of the neutral position, the switch 19 is opened. The vacuum in the pipe 23 also acts on a diaphragm 45 which moves the valve 47 to divert the gases through silencer 8. To minimize engine wear due to fast running immediately after starting a pump 52 delivers lubricating oil to a valve 54 which when opened by a solenoid 56, in parallel with solenoid 28, allows oil to pass directly into the induction pipe.
Patent GB-616177-A (GB)
Abstract: 616,177. Adhering registered films. TECHNICOLOR MOTION PICTURE CORPORATION. May 22, 1946, No. 15490. Convention date, Sept. 27, 1945. [Class 98 (ii)] Films are caused to adhere to each other by wetting one film to render it tacky and rolling it into contact with another film on which it is superimposed as they pass through a vacuum chamber. As shown, a blank film 6, which has been fed through a wetting tank, and a dyesoaked imbibition matrix film 7 are fed into a vacuum chamber 13 to be seated on a pin belt 1 by rollers 14 and 22 respectively, a seating belt 20 being employed in addition to position the matrix on the blank, as described in Specifications 307,659 and 585,745. Air traps 40 are arranged at each of the entrances and exits to the chamber 13 and include two contacting sets of rubber-covered rollers, the shafts of the lower set being supported by spring arms attached to the chamber casing. The chamber is exhausted by ducts adjacent each trap and at the centre of the chamber. A heater 57 may be employed to soften the gelatin layers of the film further to ensure adherence between the films. Specification 616,168 is referred to.

Title: Improvements in and relating to vegetable grading apparatus
IPC: B07B13/07
Filed: 1978-10-03
Abstract: A vegetable grader is described which may be used for any articles to grade them according to size but is particularly adapted to the grading of carrots and like root crop vegetables. Size discrimination is achieved by using on inclined bed of diverging rollers (10) the in relative spacing between adjoining rollers being adjustable to obtain the desired grading characteristic between one end of the bed and the other.
