Abstract: 1,099,668. Fluid-pressure servomotor systems. BARBER-COLMAN CO. Sept. 7, 1966 [Sept. 15, 1965], No. 40012/66. Heading G3P. [Also in Division F4] In an air-conditioning system, air flows to a room S via ducts 10, 18 mounted in a chamber 13 above the ceiling 9 and spaced distributors such as 14. A damper 22 controls the exit from duct 10 and duct 18 has a Venturi 19 which induces air into duct 18 from the chamber 13 via dampers 25. Dampers 22, 25 are controlled by unit 24 and room thermostat 11, the arrangement being such that when damper 22 is fully open dampers 25 are closed. The air in chamber 13 will be warmed by heat from lights recessed in the ceiling. To allow accurate control of room temperature, the static pressure of the air in duct 10 upstream of the damper 22 is maintained constant by a butterfly damper 26. The latter is elliptical and is supported on a spindle 29 having an arm 30 connected to the top of a bellows 27. A bracket 35 on the damper 26 prevents the latter from completely closing duct 10. Air is admitted to the interior of the bellows from Pitot tube 41 via conduit 40 and escapes via a port 47 controlled by a ball 46. The latter is carried by a disc 48 mounted on a diaphragm 50 which has the annular space 53 thereabove connected by conduit 56 to orifice 57 in the wall of duct 10 downstream of the damper 26. The ball is seated by spiral spring 58 Fig. 6 (not shown). In operation, the damper 26 is biased to the closed position by the weight of arm 30 and the air flow, and is in equilibrium when these forces are balanced by the bellows. A rod 38 carried by damper 26 prevents the latter from occupying a fully horizontal position in which it would experience no bias from the air flow.

Title: Centrifugal Separators
IPC: B04B1/14
Filed: 1966-09-09
Abstract: 1,162,121. Centrifugal separators. WESTFALIA SEPARATOR A.G. 9 Sept, 1966 [17 Sept., 1965], No. 40350/60; Addition to 984,738. Heading B2P. In a modification of the separator described in the parent Specification, the control chamber 3 is located centrally of the separator and is supplied with the whole of the liquid to be centrifuged by means of a stationary supply pipe 2 the lower end of which is provided with a skimming plate 8 having skimming passages 9 communicating with the bore of the supply pipe. Air bleed holes 14 are provided in the skimiming plate. In Fig. I, which represents a clarifier for removing solid impurities from a liquid, the liquid passes from the chamber 3 via passages 4 and enters the separating chamher 5 through passages 7 around the outer edge of a bottom plate 6. When after a certain operation time the separated solids in the chamber 5 reach the outer edge of the plate 6, the penetration of liquid to 'be centrifuged through the passages 7 is prevented and the free surface of the rotating ring of liquid formed in the chamber 3 then instantaneously moves inwards. When the skimming plate 8 comes into contact with that ring, the .liquid is forced back through the skimming passage 9 into the pipe 2 and leaves again through the opening 10. Back pressure builds up in the pipe 2 and prevents further inflow cf liquid to 'be centrifuged, the latter rising through a passage 11 and lifting a float 12 which closes a contact 13 thereby initiating de-sludging. The switch 12, 13 can either set a control equipment into operation or can directly operate a solenoid valve in a pressure line leading to the opening or closing chamber associated with the piston controlling the solids discharge openings in the wall of the centrifuge drum. The purified 'liquids flows via passages 19 into a shimming chamber 20 from which it is received by a skimming member 21 which communicates with an outlet conduit 23. In an alternative arrangement, the opening 10 at the bottom of the supply pipe 2 is closed, the liquid being fed through the skimming passages 9 in normal operation. In Fig. 2, which shows a separator for removing solids from a mixture of liquids which are separated into light and heavy fractions, a passage 17 is provided above a seperating plate 15 for the discharge of the heavy liquid fraction towards an outlet 16. When separated solids reach the outer edge of plate 15 the heavy liquid fraction is prevented from leaving through passage 17 and collects in the separating chamber 5. When that fraction reaches the inner edge of passage 18, the light liquid fraction can no longer enter the set of plates so that displacement of the free liquid level in the chamber 3 commences.

Abstract: <PICT:0857449/III/1> On rotation counter-clockwise of a handle on a shaft 13, a roller 17 is moved into successively deeper peripheral depressions 16 in a disc 14, thus reducing the pressure of a pressure roller 2 against the master cylinder 1 of a rotary spirit duplicating machine .A cam 29 on the shaft 13 engages a rod 25, thereby raising a liquid supply tank 7 to a position 71, a valve needle 10 normally resting against the bottom of a liquid container 6 allowing a conical valve body 9 to drop and shut off the liquid supply.  Liquid from the container 6 is conducted by a wick 5 to a roller 3 for moistening copy sheets fed between it and a feed roller 4.  Towards the end of the lifting of the tank 7, the cam 29 engages an arm 30 of a lever 30, 21 pivoted at 22, to release the pressure of the roller 4 against the roller 3.

Title: In-line veneer production process and apparatus
IPC: F26B25/22
Filed: 1964-10-08
Abstract: 1,079,049. Woodworking. WEYERHAEUSER CO. Oct. 8, 1964 [Oct. 10, 1963], No. 41081/64. Headmg B5L. An in-line veneer production process comprises peeling logs into veneer, conveying the veneer to storage trays, conveying the veneer from the trays into a veneer dryer, and drying the veneer in the dryer. The logs 4 are initially fed by a conveyer 5 and handling equipment 7 to a lathe 8 at a peeling station 3 where they are placed in line with chucks 9 by calipers 10. A knife 11 peels veneer from the logs which rotate at varying speeds so that the veneer 18 is produced at a constant speed. The initial discontinuous veneer caused by the irregular shape of the log is conveyed by a gate 14 to a waste shoot 15. The veneer 18 is fed by tipples 19 to a storage section 20 having upper and lower sections 21, 22 of storage trays each of which consists of a conveyer belt which moves until it is completely full, the tipple 19 then being moved to direct the veneer to the next tray. The stored veneer is discharged as required by conveyers 24 to a section 30 where unusable veneer is cut and discharged to a waste conveyer 35 by clippers 31, 32. From the section 30, the veneer is then transferred by conveyers 38 to a second storage section having upper and lower sections 41, 42 of storage trays similar to the section 20. Conveyers 45, 46 to further conveyers 51, 52 in a feed section 50 which pass the veneer to a drier 60 having upper and lower conveyers 66, 67. The conveyers 51, 52 are so operated that there is an unbroken line of veneer passing through the drier. From the drier, the veneers pass through a cooling section 63 to a section 70 having moisture meters and markers 71, 72 which sense the moisture content of the veneer and, if above a predetermined content, mark the veneer to indicate to an operator at clippers 75, 77 which veneer is satisfactory and which requires further drying, the latter then being reintroduced to the drier by means of a feeder 54 or to the storage trays 40 by a conveyer 37. The operator cuts the veneer with the clippers to the correct size, the cut sheets then passing to a table for sorting into stacks 80. During its travel, the grain of the veneer is transverse to its direction of movement. The peeled veneer both from the outer portion or the inner portion of the log may be passed from the peeler through whichever line of the drier is convenient, or, the outer portion may go through one line and the inner portion go through the other line.

Title: Improvements in and relating to night depository equipment
Inventor: WALKER FRANCIS GRAHAM
IPC: E05G1/00
Filed: 1959-12-07
Abstract: 904,497. Night safes. CHUBB & SON'S LOCK & SAFE CO. Ltd. Nov. 30, 1960 [Dec. 7, 1959], No. 41579/59. Class 18. A night depository equipment comprises a rotatable receptacle 22 to receive valuables when a lockable flap 2 is opened and an electric motor 5 to rotate the receptacle 22 and thus to deliver the valuables to a storage safe. The flap 2 is unlocked by turning a key in a lock 10 which by means of a cable 9 draws a pin 8 from an extension 7 of a sliding rod 6 allowing the rod 6 to slide and thus the flap 2 pivoted at 3 to open. A ramp 20 on the rod 6 engages one arm of a bell crank 17 turning it against a spring 19 and thus allowing a four armed lever pivoted at 14 to turn under the action of a second spring 15. One arm 16 of the four armed lever closes a switch 13. Valuables are placed in the receptacle 22 mounted on a drum 21; the flap 2 is then closed and locked, the rod 6 returning to its initial position in which it closes a second switch 11 in series with the first, supplying current to the motor 5 which turns the drum 21 via a worm drive. When the drum 21 has turned through a suitable angle vanes 28 engage the contents of the receptacle 22 removing them therefrom so that they fall under gravity into a shoot 29 leading to the storage safe. When the drum 21 has completed one revolution the cam 33 engages a further arm 34 of the four armed lever turning it against the spring 15 and releasing both the switch and the bell crank 17, the latter thereafter holding the arm 16 away from the switch 13. The flap 2 cannot be reopened while the drum is rotating since a protrusion 31 on a lever 30 pivoted to the rod 6 engages the end of an arm 32 of the four armed lever which is in its released position. This engagement does not occur when the flap 2 is first opened since the arm 32 is then in its depressed position and the arm 30 rides up over it.
