Title: Improvements in and relating to fuel-injection carburettors
IPC: F02D9/00
Filed: 1941-04-16
Abstract: 600,552. Spray carburetters. SOC. ANON. SOLEX. April 16, 1941, No. 4979. Convention date, May 24, 1940. [Class 7 (iii)] In a carburetter having the fuel fed under pressure by a pipe 6 and past a valve 9 controlled by a diaphragm 10 acted on by the fuel pressure, and at the opposite side by the suction in the intake 1 transmitted by a connection 18, 19, this suction is also made to act on a second diaphragm 17 which is constructed of greater area than the first diaphragm 10 so as to multiply the effect of the suction in the valve. The fuel chamber 7 at the left of the diaphragm 10 is connected by a passage 12, and also by a nozzle 29, to a further nozzle 14 separated by an air space from the spraying-nozzle 5 of venturi form, the passage 12 being controlled by a slide valve 30 actuated by a lever 32 and a diaphragm 35, subjected at the right-hand side to the suction in the induction pipe through a connection 39 and 40 or 41, the effect being such that the passage 12 is closed at light loads. The contiguous sides of the diaphragms 17 and 35 are in communication by a hole 42 and are connected to the atmosphere at 28. The valve 30, when raised to close the passage 12 for running light, also opens a passage 43 connecting the chamber 16 between the diaphragms 10, 17 to a chamber 44, which is connected to the intake pipe by openings 45, 46, the latter of which is traversed by the edge of the throttle 2 as this is opened, the arrangement being such that, when running light, there is an increased suction action on the diaphragm 17 so as to give a further opening of the valve 9 and consequent increase in the fuel pressure. The diaphragm 35 also serves to produce an increased fuel supply when the throttle is suddenly opened for acclerating. The suction action in the chamber 16 may be further modified by an air-inlet valve 22 on the pipe 19, which is opened, when the throttle is partly closed, by suction action on a diaphragm 24 ; or such a diaphragm may control a needle valve controlling a passage connecting the opposite sides of the diaphragm 17. The fuel supply may be increased at starting by means of a hand lever 60 acting on the diaphragm 17 through a spring 58 ; or the lever 60 may be connected with lost-motion to the throttle control 3. In further modifications, there may be two nozzles 29, one of which is controlled by the valve 30 ; and an altitude control may be provided by a barometric capsule which controls an air-inlet valve on the pipe 19, or limits the downward movement of the valve 30.

Title: Blood fractionizing method and means
Inventor: BULL B S
IPC: G01N33/483
Filed: 1972-02-04
Abstract: 1376664 Centrifugal separators COULTER ELECTRONICS Inc 4 Feb 1972 [8 Feb 1971 22 Oct 1971] 5315/72 Heading B2P A centrifuge for fractionising whole blood comprises a centrifuge head 24, Fig. 2, connected to a substantially vertical shaft 26 driven by a motor 22, tube holders 46 carried by the head adjacent its outer periphery and arranged to receive blood-containing sample tubes 16 in a substantially vertical disposition, the motor being adapted to rotate the head 24 at such a speed that a greater than gravity centrifugal force acts laterally on the columns of blood samples contained in the tubes, and means being provided for causing rotation of each column of blood about its own longitudinal axes when the gravity force acting downwards relative to the column is greater than the force acting laterally of the column. The head 24 comprises a spool 30 mounted for rotation on a shaft 32 which has an enlarged end 34 with a passage 36 to receive shaft 26 of the motor 22. The tube holders 46 are carried in openings in the spool 30 and are provided with pinion wheels 48 which mesh with a spur wheel 38 mounted on the shaft 32 and rotating therewith. The tube holders may be transparent and graduated scales 52 may be mounted on the spool 30 adjacent the tube holders. A pin 54 secured to the upper disc 56 of the spool 30 projects into an arcuate slot 58 in the spur wheel 38, the length of the slot being selected to ensure that rotation of the pinion wheels 48 is limited to 180. After the pin 54 reaches the end of slot 58, no further rotation of the pinion wheels 48 can take place. The motor 22 is brought to rest and then started in the reverse direction. At this time, the pinion wheels 48 must first rotate, owing to the inertia of the spool 30, until the pin 54 reaches the other end of slot 58.. Thus the holders and hence the tubes 16 are caused to rotate exactly 180 with each reversal of the motor 22. An interlocking device 60 comprises a metal strip 61 pivotally secured to a block which in turn is attached to the inside wall of the upper disc 56. The strip is pivoted at 64 to move in a radial slot 66. A mass 68 is carried at the lower end of the strip. When the spool 30 is rotating, the mass 68 is held radially outward of the spool so that the strip 61 engages the spur wheel 38. When the motor speed falls to its rest position and the strip disengages from, the wheel 38. In lieu of the pin and slot arrangement, a spoked wheel gear can be utilized instead of wheel 38, with a pair of pins disposed between the spokes so as to limit the rotation of the pinion gear 48 and, with it, the tubes and blood therewithin. Two other embodiments are described.

Title: Apparatus for the safe working of single line railways
IPC: B61L23/24
Filed: 1921-02-16
Abstract: 180,404. Baker, P. M. Feb. 16, 1921. Staff, tablet, and ticket systems.-An apparatus for use in single line working requires the use of a token tu prepare for the signal or point operations necessary for the departure of a train. Confusion between tokens is avoided by variations in the tokens for adjacent sections. The bar A is inserted in the run of the signal wire, and carries a detent B which engages the rack C. A slide D rests on the bar A and is held by a spring detent J engaging the rack G in the casing. The casing has apertures covered by lids H, L which can only be opened when the slide is in the correct position. When the token has been inserted over the peg F and the lid H is closed, the detent J is depressed, and the slide D is then moved until the token is under the lid L and .can be recovered. During this movement the ramp M of the slide depresses the tail of the detent B thus leaving the bar A free so that the signal can be lowered when desired. When the signal wire is pulled, the stud N on the bar A returns the slide D to its original position. In a modification, the slide D is replaced by a semicircular plate a locked by a detent J engaging the ratchet G. A recess E and stud F are provided for the reception of the token. After the insertion of the token the handle S can be operated to move the lever c into its upward position in which it is held by the electromagnet d until the circuit is broken by the treadle t on the passage of the train. The lever c then falls, replacing the signal in the stop position. The insertion of the token and operation of the handle S allows the signal to be operated by the signal wire w<1> and after the removal of the token the apparatus remains locked until a token is again available.

Abstract: 806,337. Internal shoe-drum brakes. CLARK EQUIPMENT CO. Feb. 18, 1957 [Feb. 27, 1956], No. 5402/57. Class 103 (1). An automatic adjustment device for internal shoe-drum brakes comprises an annular member 40, fixed on the brake support or backing-plate 22 by a bolt 52, the members 40 having lugs 48 on one face, which are held in engagement with the lugs 56 on a castle nut secured to the plate by the force of a washer spring 60 between the bolt head and the back of plate 22. The member 40 has a projecting pin 42, which is disposed within a hole 66 in the brake shoe web with a clearance equal to the desired shoe-drum clearance. When the shoe is actuated to apply the brake, if the shoe lining 28 has worn away sufficiently to absorb the normal clearance, the shoe will rotate the pin 42 on bolt 52 and, on release of the brake, the pin will be held by the friction between the faces of the lugs 48 and 56, the springs 30, 32 resetting the shoe clearance. If, however, sufficient shoe lining is worn away to allow lug 48 on part 40 to drop into recess 58 between lugs 56, the washer spring 60 will be relaxed and no longer exert sufficient force for the device to provide automatic adjustment.

In a method of operating an injection moulding machine which operates automatically, and which machine includes two mould parts, each part supported by a carrier plate movable relative the other, the ejection of the moulded article from the mould is monitored and the subsequent closing movement of the mould is controlled in dependence of such monitoring; during the mould opening movement at least one region of the mould covered by the article before ejection is sensed without contact, and the closing movement is controlled in dependence of the result of the sensing operation. As described a sensing device A which may be a signal emitter and receiver, or an electrocapacitive device, is carried by an arm T extending from a movable carrier plate P supporting a mould core K in association with a mould part M. The sensing device operates a relay in a circuit controlling two control relays which, in turn, control the operation of an evaluating relay. If, on removal of the mould core after a moulding step the article remains in the part M the sensing device operates its relay to operate one of the control relays and the evaluating relay to interrupt the machine and give an optical or acoustical warning signal; if the article sticks to the core the other control relay is operated to produce the same result.
