Title: Improvements in and relating to control devices for superchargers
IPC: F02D9/00
Filed: 1941-07-23
Abstract: 550,428. Fluid-pressure servomotor-control systems. BRITISH THOMSON-HOUSTON CO., Ltd.. and MORRIS, P. D. July 23, 1941, No. 9322. [Class 135] Supercharger control mechanism comprises a primary relay consisting of an element responsive to absolute boost pressure, a pilot valve and servomotor, and a secondary relay consisting of a pilot valve and main servomotor, the secondary relay being influenced by the primary relay and also by a centrifugal governor driven by the supercharger. In the form shown, the pressure sensitive element consists of bellows 7, 71 separated by a member 8 acted on by a spring 9, the bellows 7 being subject internally to the boost pressure, and the bellows 71 being evacuated When the boost pressure falls, the sensitive element acts through a lever 10 to cause a sleeve 11 to diminish leakage from below a piston 45, a pilot valve 38 thus being lifted to cause raising of the piston and rod 14 in the servomotor 3. Rack and pinion gear is thus operated to cause resetting of the sensitive element and the valve 38 through a cam 34 and lever 39, and the lifting of the left hand end of a lever 16 through a cam 15. The movement of the lever 16 sets a valve sleeve 22 to admit oil to a cylinder 6 to depress a piston 23 and partially close a valve 35 so as to increase the speed of the exhaust gas turbine 35<SP>1</SP> driving the supercharger. The supply of oil to the cylinder 6 is cut off by the action of a speed governor 4 driven by the supercharger on a valve 21, and by an incline 33 on the piston rod 24 acting through a bellcrank lever 30 on the lever 16 and sleeve 22. Should the supply of operating oil fail, a piston 27 is raised by compression springs in order to open a valve 28 to permit communication between the chambers on opposite sides of the piston 23 and finally to raise the piston and its rod 24 to the maximum extent. Setting of the boost pressure to a desired value is effected by adjusting the position of the fulcrum 12 of the lever 10, and the limitation of supercharger speed above the critical altitude is effected by the speed governor 4 acting to open the valve 35.

IPC: H03K3/45
Filed: 1953-04-07
Abstract: 749,628. Converting. BRITISH THOMSONHOUSTON CO., Ltd. April 5, 1954 [April 7, 1953], No. 9374/53. Class 38 (2). For supplying from A.C. a load E, which may be an electrostatic precipitator, with unidirectional pulses, the voltage being maintained in the same direction between the pulses at a predetermined level, the pulses may be developed from alternator G in an arrangement including reactors and condensers, and the interpulse voltage obtained by rectification at M of the output of alternator G1. Fig. 1 shows a pulsing circuit in which the alternator G supplies a substantially resonant series connection of inductor L and capacitor C, the pulses being produced by the D.C. saturated inductor P, and transmitted to load E through pulse transformer Tp and decoupling condenser C1. The pulse generator may alternatively include a plurality of saturable inductors with associated capacitors, Fig. 2 (not shown) as described in Specification 666,574. The pulse amplitude may be altered by varying the output voltage of generator G or the premagnetizing current of saturable inductor P, the pulse frequency may be altered by varying the speed of alternator G, and the interpulse voltage may be altered by varying the voltage of alternator G1, all by remote control if desired. The pulse shape may be varied by connecting a resistance R across the load or primary winding of transformer Tp if the load is capacitative, otherwise by a resistance-capacity network.

Title: Attendance time recorder
IPC: G07C1/00
Filed: 1975-03-06
Abstract: 1498103 Attendance time recorders; counters SIMPLEX TIME RECORDER CO 6 March 1975 [13 March 1974] 9424/75 Headings G4T and G4D [Also in Division B6] A printing device for printing multi-digit numbers particularly for the clock times in attendance time recorders comprises a plurality of coaxial and adjacently disposed number wheels 26, 28, 30, 32 of annular form with internal teeth 170 for being indexed, by an indexing pawl 152. The number wheels are of equal diameter with the circumference thereof supporting the number sequences occurring in different digits in the form of printing types 164. The number of internal teeth correspond to the number of printing types of the appropriate number wheel, the indexing pawl having an indexing dog for each wheel, 156, 158, 160, 162 the length of which progressively decreases from number wheel to number wheel beginning from the number wheel with the lowest digit value. Each of the wheels except that with the higher digit value has teeth A6 of increased depth, these allow the deeper engagement of the associated indexing dog at those positions at which an adjacent number wheel with a higher digit value is to be simultaneously indexed. The time is printed on a real time basis; that is zero is taken as a certain time and the hours are measured from them whilst allowing for tea and lunch breaks. Printing head 14 is pivotally mounted on shaft 16 by plates 20. The head is moved between side walls 10 by means of servomotor 70, pinions 74 and gearwheel 76, engaging with bush 38 which is attached by bar 44 to a plastics bush 22 mounted slidably on shaft 16. Motor 70 is activated by a current pulse from a control system of the time recording clock (not shown). Its action is terminated by a switch 72 that is controlled by lever 92 and disc cam 82. The head is moved about shaft 16 to print by means of magnet 56. Indexing of the number wheels is initiated by indexing wheel 110 rotating lever 102 which in turn pivots indexing lever 34 about shaft 142. To cater for rest periods wheel 110 is only in engagement with lever 102 when a plunger magnet (134) Fig. 3 (not shown) is activated. The magnet is controlled by a time recording clock programme control system (not shown). The number wheels are rotatably mounted on a bearing cylinder 140 that is mounted on the side member 20 which is on the left of Fig. 1. The indexing pawl 152 is rotatably mounted on lever 34 and has an arm 155 that extends into cylinder 140 and on which the indexing dogs 156 to 162 are mounted. These can engage with teeth 170 and as previously mentioned deeper teeth 176 allow an adjacent number wheel with a higher digit value to be simultaneously indexed at the requisite time. Pawls 202 prevent reverse rotation of the wheels. In a modification Fig. 10 (not shown) the ratchet is shaped and biased to ensure accurate location of the wheels. A plate 52 carries a card retaining means (216) Figs. 10 and 11 (not shown) and which is mounted on the casing of the clock (not shown) to form a rear wall 210. An indexing device moves a stop (218) in known manner.

Title: Improvements in and relating to carbonyl-containing compounds
IPC: C07C27/22
Filed: 1949-04-07
Abstract: Oxygen - containing organic compounds, especially aldehydes, are made when an olefine is reacted in the liquid phase in countercurren-with CO and H2 in the presence of a carbonylation catalyst at elevated temperature and pressure in a reactor so that the olefine is introduced above the point of entry of the carbonylaing gas which is introduced at an intermediate point in the reactor and a gas rich in hydrogen is introduced at a point below the point of introduction of the carbonylating gas.  The olefine may be added dissolved in an inert diluent, e.g. saturated butene trimer, 3,5,5 - trimethyl hexanol, dinonyl ether and di-isobutylene when olefines containing up to 5 carbon atoms are being treated.  Preferably the inert medium is added above the point of entry of the olefine.  Preferably the reactor is cooled by indirect cooling coils and the carbonylating gas may be used for cooling.  Preferably the reactor is lined with a metal not readily attacked by CO, e.g. Cu, Ag or stainless steel. Liquid products are removed at the bottom of the reactor. The gas containing hydrogen is used as a stripper so that a suitable arrangement comprises in descending order a carbonylation zone, a stripping or carbonyl decomposition zone and a filtering zone.  The magnetic separator of Specification 670,423 may be used.  The decomposition zone is desirably of such dimensions as will give a residual CO content in the product of preferably not more than 1 litre at N.T.P. per kilogram of liquid product and when unpacked narrow diameter reactors are used a depth of at least 10 feet is preferably required.  When the catalyst is cobalt a depth of at least 4 feet is sufficient to reduce the dissolved cobalt of the liquid to about 0.002 per cent by weight. Preferably the hydrogen is pure hydrogen and free from oxygen. The product is worked up for aldehydes, e.g. by the flash distillation of Specification 655,976, [Group III], and hydrogenated to alcohols, e.g. at 250 atmos. and with a copper chromite catalyst in a separate stage.  Preferably the molar ratio of H2 : CO is 1 : 1 although a ratio of 4 : 1 is also specified, but if ordinary steel equipment is used this ratio should be not less than 2 : 1 and preferably about 3 : 1.  Excess gases may be recycled.  The preferred catalyst is cobalt, particularly as the carbonyl, and it may be injected as such or formed from a metal salt dissolved in the liquid reactant or medium, or from the metal on a support by reaction with CO.  0.1 to 1.0 per cent is a suitable concentration of cobalt dissolved in the feed.  Reaction conditions specified are 200-300 atmos. gauge and 100-180 DEG  C. for carbonylation and similar temperatures for p  decomposition. Preferably the pressure is 250 atmos. when the volume ratio gas: olefine is preferably 1000 : 1 to 3000 : 1 and the temperature of the decomposition zone is about 150 DEG  to 170 DEG  C. Cyclohexene is a specified aldehyde.  In an example, di-isobutene is carbonylated and the product hydrogenated to 3,5,5-trimethyl hexanol.

Abstract: 1356365 Electric incandescent lamps DUROTEST CORP 1 March 1972 9660/72 Heading H1F In a method of forming a filament for an electric lamp by winding a tungsten wire 16 on to a mandrel 12, annealing the wire on the mandrel and removing the wire from the mandrel by solution of the latter, to prevent impurities from the mandrel from diffusing into the wire either (as shown), the mandrel, or (Fig. 3, not shown) the wire is provided with a coating 14. The process is particularly applicable in the case of steel mandrels, which may be formed from steel wire coated by plating or cladding with copper, copper-silver or copper-indium alloy, drawn to work-harden the coating and severed. At the annealing temperature the copper or alloy melts without dripping to bond the coil to the mandrel, which helps to retain the coil geometry when it is cut into individual filaments. The coating also improves solution of the steel mandrel in acid by inhibiting passivation. Coiled coils may be made using a molybdenum mandrel.

IPC: F02D9/00
Filed: 1920-04-06
Abstract: 141,349. Gruebler, F. April 6, 1920. Regulating; valves.-In four- or two-strokecycle engines, additional air is supplied to the engine cylinder by a separate pump according to variations in the atmospheric pressure, the pressure in the engine cylinder is kept constant by a regulating-valve in the pump inlet, and the pump discharges the air, without storage in a reservoir, into the engine cylinder so as to avoid loss of compression pressure at any altitude or engine speed. As shown, air supplied by a rotary pump g is admitted at the end of the suction stroke by a slide valve f through a piston-controlled port d, the quantity of air being regulated at different altitudes by a hand-controlled valve m on the pump inlet. The main charge is drawn in from a carburettor through the inlet valve c, and an auxiliary supply of fuel may be injected into the extra air charge through a nozzle y with a regulating- cone z. This fuel is delivered by a rotary pump x driven from the engine through change-speed gear. In modifications, the fuel supply may be controlled by throttling in the nozzle y; the extra fuel may be supplied at the inlet side of the pump g; the main fuel supply, or the extra fuel supply, may be dispensed with; the delivery from the air-pump may be at the cylinder head; and a single valve may be used for inlet and exhaust. The Specification as open to inspection under Sect. 91 (3) (a) states that the valve m may be controlled automatically, and that, for motorvehicles, the control of the supplementary carburettor may be coupled to that of the main car burattor. This subject-matter does not appear in the Specification as accepted.
