Title: Internal combustion engine fuellcontrol system
IPC: F02D41/34
Filed: 1973-07-23
Abstract: 1373198 Electronic fuel injection systems for I C engines BENDIX CORP 23 July 1973 [23 Aug 1972] 35001/73 Heading G1N In an I. C. engine electronic fuel injection system of the type having a fuel control computer 20 responsive to signals from at least one sensor of an engine operating condition to provide an injection command signal to at least one fuel injector 12, an air density computer 23 is provided and comprises a temperature sensor 24 for genetating a signal representing the temperature of air in the engine intake manifold, a circuit responsive to the temperature signal to generate an air density signal, this signal being applied to the fuel control computer to modulate the injection command signal as a function of the air density signal so that the desired fuel to air ratio is maintained during the engine transient warm-up period.  The computer 20 may be of the type which produce a single pulse train triggered in syn-  chronism with engine rotation and having a pulse duration determined by signals from an inlet manifold absolute pressure sensor 21, an engine temperature sensor, and the air density computer, Fig.3 (not shown), or of the type which provides a double pulse train, the first pulse having a duration determined by signals from the pressure sensor 21 and the air density computer, and the second pulse being triggered by the first pulse and having a duration dependent upon the duration of the first pulse and the signal from the engine temperature sensor, Fig.4 (not shown). As shown in Fig.5, the fuel control computer is the double pulse type of system described in U.K. patent No. 1292771 modified to produce only the second pulse. The air density computer shown at 200 includes a temperature sensor in the form of a transistor 201, a constant current source 202-205 and an operational amplifier 206. In operation, the voltage across transistor 201 is directly proportional to air temperature and the amplifier 206 inverts this voltage and superimposes a predetermined D. C. bias signal thereon to provide the air density signal. This signal is applied to the emitter of a transistor 142 in the fuel control computer so that the pulse duration is caused to be increased by this signal until the engine temperature reaches a predetermined value. The temperature sensor is mounted in the air intake manifold, preferably close to the intake valve of a cylinder, Fig.2 (not shown).

Title: Methods and arrangements for separating condensable impurities from mixtures of inertgases and vapours produced during the deodorisation of organic products
Inventor: KEHSE WOLFGANG
IPC: B01D5/00
Filed: 1965-08-17
Abstract: 1,066,707. Condensing impurities in gases from deodorisers. PINTSCH BAMAG A. G. Aug. 17, 1965, No. 35114/65. Heading B1B. Condensable impurities are separated from a mixture of inert gas and vapours produced during deodorisation of organic materials, e.g. oils, fats and waxes, in a deodoriser 9 by washing the mixture in a washer 5 with the raw starting material. Crude oil from tank 1 passes through pump 2 to a cooler 3, for cooling to slightly above solidifying point, and then through nozzle 4 into washer 5. The spray of oil washes vapours rising from the deodoriser 9, filling bodies 7 preventing liquid particles from reaching a vacuum unit connected at 8. The oil charged with fatty acids collects at the washer base and is transferred to a refining stage 10. Unrefined crude oil may be recirculated to the washer 5 via valve 12, and crude oil may feed directly to the refining stage via valve 11. After treatment with alkalies in stage 10, which may be follewed by drying treatment and treatment with Fuller's earth, the pre-treated oil passes to the deodoriser for treatment with finely divided steam. Pretreatment may alternatively be effected by a distillation process prior to or together in a unit with the deodoriser. Figs. 2 and 3 not shown. The main quantity of impurities present in the vapour steam from the distillation are first separated by washing with cooled fatty acid before subsequent re-washing with the starting product together with the vapours from the deodoriser.
Patent GB-306239-A (GB)
Title: Improvements in or relating to delivery apparatus for stacking sheets, cards or the like in counted batches
IPC: B65H33/02
Filed: 1927-12-28
Abstract: 306,239. Bingham, A., and Molins Machine Co., Ltd. Dec. 28, 1927. Delivery apparatus.- In apparatus for stacking in counted batches, sheets, cards or the like delivered from printing, cutting, and packetmaking machines, the cards 1, Fig. 1, are moved one by one into a stacker 4, and after a predetermined number have been collected, a finger 7 is moved into position to support the batch and separate it from the succeeding batch. As applied to the machine described in Specification 285,540 for making and stacking flattened packet-shells, wherein the shells are delivered by a conveyer 3 and pushed into the stacker 4 by an oscillating blade 5, the fingers 7 are carried by an endless chain 6 moving with a speed corresponding to the rate of delivery of the shells. The chain 6 passes over a sprocket wheel 8 fixed to a shaft 32 operated by pawl-and-ratchet mechanism 9, 10 from a shaft 27, in time with the normal delivery of the shells. Mechanism is provided for preventing operation of the shaft 32 if no shell is delivered, and consists of a roller 23, Fig. 3, carried by an arm 24 fixed to a shaft 25 oscillated through a slip-clutch 29 from an arm 28 connected by a link 26 to an eccentric on the shaft 27. This mechanism lifts the roller 23 periodically to clear the pusher pieces on the conveyer 3 but allows it to drop below its normal position if no shell is present on the conveyer. This abnormal movement causes a link 33 fixed to an arm 34 on the shaft 25 to operate a bellcrank lever 35, Fig. 1, so as to strike a pin 36 on the pawl 10 and lift it out of contact with the wheel 9. A member 16 pivoted on the shaft 32, is recessed to receive a sliding block 14 on a lever 13 moved at intervals under the action of a spring 18 by the engagement of a projecting part 15 thereon with a snail cam 12 on the shaft 32. Such movement allows the member 16 to move forward at the desired time under the action of the spring 18 through a lever 19 controlling the tension of the chain 6, so that a projecting nose 17 thereon pushes the blade 7 into the stacker. In order to prevent the movement of the member 16 until the blade 5 has moved the last shell of the batch into position, a pivoted latch 20, Fig. 2, is provided, which oscillates under the action of a spring in unison with the blade 5 through a contact screw 22. In the lower position of the blade 5, the latch 20 engages a lug 21 on the member 16 and prevents its inward movement, but when the blade 5 rises, the member 16 is released so that the nose 17 pushes the blade 7 into position. A bell 38 is rung to warn the operator when a further batch of shells is ready for removal.
Patent GB-783042-A (GB)
Title: Process for the production of substituted para-benzo-quinones
IPC: C07C50/24
Filed: 1955-12-07
Abstract: Substituted p-benzoquinones are made by treating a p-phenol sulphonic acid which is substituted at least in the o- and o1-positions by halogen atoms, alkyl or cycloalkyl groups with an oxidizing agent. The substituents in the o-and o1-positions may be the same or different.  In a modification, the p-benzoquinones are made by oxidizing a reaction mixture obtained by the sulphonation of a phenol substituted at least in the o- and o1-positions by the substituents mentioned above and having a free p-position; the sulphonation may be effected by treatment of the phenol with sulphuric acid monohydrate at elevated temperature.  Oxidizing agents specified are chromic acid and pyrolusite in acid solution.  In examples, 2 : 6-diethyl phenol is treated with 100 per cent sulphuric acid at elevated temperature, the mixture cooled, unreacted phenol removed and the filtrate, diluted with dilute sulphuric acid, is oxidized with sodium bichromate in (1) with cooling and (5) at reflux temperature, and in (4) with pyrolusite, to yield 2 : 6-diethyl-benzoquinone-(1 : 4); in further examples there are similarly made from the appropriate phenols: (2) 2 - methyl - 6 - ethyl -, (3) 2 : 6 - diisopropyl -, (6) 2 - ethyl - 6 - cyclohexyl -, (7) 2-chloro - 6 - ethyl -, and (9) 3 - methyl - 2 : 6 - diethyl - benzoquinones - (1 : 4), and in (8) 2 : 6-dichlorobenzoquinone-(1 : 4) is made by oxidizing sodium 2 : 6-dichlorophenol-4-sulphonate with sodium bichromate and sulphuric acid.

Filed: 1962-09-15
Abstract: 1,013,742. Batch weighing. J. BIBBY & SONS Ltd. July 26, 1963 [Sept. 15, 1962], No. 35249/62. Headings G1N and G1W. The weighing apparatus described in Specification 1,013,741 is improved by arranging for the amount of make-up material applied from conveyer 15 to be as small as possible by automatically adjusting the time for which conveyer 11b supplies material. This is done by causing timer T2 which starts the make up process to set timer T5. After the desired make-up weighing interval T5 supplies a signal to motor M2 which runs until a signal from the load sensing device 36 signals the correct weigh has been achieved. Alternatively if the weight signal is produced before the signal from the timer T5 the motor moves in the opposite direction. The motor is connected to a potentiometer which determines the delay of timer Ti which controls the conveyer 11b.
