Title: Carburettor for an internal combustion engine
IPC: F02M7/08
Filed: 1968-12-13
Abstract: 1,200,568. Spray carburetters. AUTOMOTIVE DEVELOPMENTS CORP. Dec.13, 1968 [Dec.14, 1967], No.59494/68. Heading F1B. In a carburetter having a throttle controlled induction passage 13 and an accelerating pump 55, Fig.4, for discharging fuel into the induction passage in response to rapid opening movement of the throttle valve 28, fuel is drawn from the pump on over-running when the vacuum in the induction passage downstream of the throttle valve exceeds a predetermined value. The accelerating pump 55 draws fuel through a check valve (63), Fig. 6 (not shown), from a float chamber defined by a cavity 18 in a member 17 forming part of the carburetter body 12 and a cavity 21, Fig.4, in a cover member 19 carrying the float 24, pivoted at 25 and controlling a needle valve 27. The pump is connected via a spring-biased ball valve (73), Fig.7 (not shown), to a passage 37, Fig. 5, in the throttle spindle 29 having air inlet passages 45 on its upstream side and mixture discharge passages 51 on its downstream side. When a predetermined vacuum is exceeded downstream of the throttle valve 28 the ball valve (73), Fig.7, is opened and fuel drawn from the pump 55. The main fuel supply to the spindle passage 37 from the float chamber is controlled by a vane 35, Fig.2, having a passage 36 extending from its lower end and communicating with the spindle passage 37. The vane 35 is connected to rotate with the spindle 29 and has its lower end variably spaced from the adjustable member 39. The float chamber is vented through a passage 93 to the carburetter air inlet 14. The vacuum advance system of an ignition distributer is connected to the interior of the float chamber in the idling position of the throttle valve to retard the ignition by means of passages (88, 89), Fig.8 (not shown), in the carburettor body 12 and a passage (92) in the fuel metering vane 35. A choke valve 94, Fig. 3, is operated by a temperature responsive mechanism 96. The choke valve shaft 95 is connected by a linkage 97 to a fast idle cam (98), Fig.1 (not shown), co-acting with an adjustable stop (99) carried by the throttle shaft. An electrical resistance heating element or water heated tube 101 is provided for heating the air on cold starting.

Title: Electrostatic marking system with a load stabilized power supply
IPC: H04N1/40
Filed: 1973-12-21
Abstract: 1448137 Facsimile recorder MUIRHEAD Inc 21 Dec 1973 [5 Feb 1973] 59545/73 Heading H4F In an electrostatic half-tone facsimile recorder, in which to reduce the loss of resolution due to the finite size of the recording stylus 27 an erase pulse of opposite polarity is applied thereto after each recording pulse, stabilization of the power supply is rendered unnecessary by making the recording and erase loads approximately equal and the loading on the power supply continuous. This is accomplished by providing a single supply 26 and causing transistors 22 and 41 to be alternately rendered conductive in response to the facsimile signal input at 10, a ballast load 45 being provided so that the erase potential (450 volts) applied to the platen 28 is lower than the recording potential (650 volts) applied to the stylus 27. The facsimile signal input preferably comprises a series of triangular waveforms which is converted into pulses by transistor 13.

Abstract: 723,312. Calculating-apparatus. RIZZIERI, I. March 20, 1951 [April 1, 1950], No. 6700/51. Class 106 (1). A setting-mechanism for a calculating-machine comprises a series of balanced levers 1 for controlling the operation of differential actuators 15, a single bank of lever keys 11 which differentially set a rocking frame 3 or the like and thereby the levers 1 one at a time, and means for step-shifting the levers. The keys rock about a shaft 6, are spring-loaded and are formed with cam surfaces 10 to cooperate with two rods 16 of the rocking frame which pivots on a shaft 4. Depression of a key differentially positions the rocking frame, the end of which carries two pivoted plates 17 which co -operate with surfaces 19 of one of the levers 1 to set it differentially. One end of each lever is U-shaped to enable material to be added to balance the lever and the other end is formed with a pin-like extension 12 to guide it during translational movement through notches in levers 14. The levers 1 are step-shifted by an escapement mechanism including a rack 24 fast to a rod 22 connected to a carrier 23 for the levers 1. Also carried by the rod 22 is a rod 20 which normally engages zero notches in the levers 14 but frees each lever 14 as it is engaged by a lever 1. When an item has been set, the levers 14 are rocked about the ends of the levers 1 differentially to operate actuators 15 as described in Specification 723,311.

Title: Photocomposition of text and pictures
IPC: G06K15/12
Filed: 1979-04-19
Abstract: The device consists of a laser light source, a modulator, a deflector, and a mirror, to produce a light spot, optical components to guide and focus the light beam on a photosensitive surface, and means to move the light beam and surface relative to each other. The combination of the movement of the mirror and the movement of the surface together cause the motion of the light spot in a certain diraction on the printing surface and the deflector causes a faster motion perpendicular to the above mentioned motion so that an unmodulated light spot would expose on the surface a stripe consisting of parallel lines. The part of text or figures intended in the area of one stripe is written by modulating the light using the modulator. <IMAGE>

Title: An apparatus and method for separating entrained vapour from a gas
IPC: B01D5/00
Filed: 1979-12-01
Abstract: An apparatus and method for separating entrained vapour from a gas provides casing 1 enveloping a finned primary heat exchanger 2 and a coaxial vortex tube 4. Compressed gas passes into the casing and down a cooling heat exchange passage A. A portion of the gas is then fed in a tangential stream into the vortex tube 4 where it separates into an outer hot layer which rises and an inner axial cold layer which falls and is removed by passages h and f to become a cooling medium for the primary heat exchanger. The hot gases in the vortex tube heat the tube wall and form a secondary heat exchanger which reheats the cooled gas from the primary heat exchanger in passage D. Condensed vapour falls into an automatic cistern which intermittently ejects a batch of this liquid to the exterior. The cistern includes a float-operated valve 31,36 which is held in its open position by a magnet 34. <IMAGE>
