Title: Method and apparatus for forming rigid paper products
IPC: B31B50/59
Filed: 1964-01-22
Abstract: 995,075. Moulding articles from paperboard. STANDARD PACKAGING CORPORATION. Jan. 22, 1964 [Feb. 15, 1963], No. 2813/64. Heading B5A. [Also in Division B6] A rigid paper article is produced by placing a circular paper-board blank 15 of high moisture content, e.g. 20% to 35% by weight, between a pair of heated forming dies 10 and 12. The upper die 12 is lowered from the position shown in Fig. 3A and a retaining ring 14 under the action of pneumatic cylinders cooperates with the die 10 to grip the edge of the blank. The dies 10 and 12 have electric heating elements 26 and 28 respectively, and to form the article the die 12 is lowered relative to the ring 14 to the position shown in Fig. 2 in which it co-operates with the die 10 to shape the blank 15 and vaporize the moisture. The vapour escapes through annular grooves 34, 35, 36, 42, 44, 46 which communicate with the atmosphere through vents 37 and 40. The vapour may be withdrawn by connecting the vents to suction. To prevent undue compression of the blank adjustable stops 62 are provided in the retaining ring 14. The dry article is removed after withdrawal of the die 12 and ring 14 by raising the central portion 30 of the die 10. Removal may be assisted by an air blast directed through a passage 68 in the portion 30. Before pressing the blank may be printed, plastic coated or moisture-proofed. The paperboard may alternatively be fed between the forming dies in sheet form from which blanks are severed by a knife edge on the outer edge of the ring 14.

Title: Hydraulic pressure control means
IPC: G05D16/18
Filed: 1946-01-30
Abstract: 606,942. Pressure-regulating valves. NEW YORK AIR BRAKE CO. Jan. 30, 1946, No. 2955. Convention date, Feb. 26, 1945. [Claas 135] A hydraulic pressure control device comprises a hollow piston 18 having ports 22 controlling the passage of pressure liquid from a supply connection 12 to an outlet 23, and a restricted aperture 19 whereby the pressure liquid in the outlet has access to a space to the right of the piston, the pressure in this space being determined and maintained constant by a spring- loaded ball valve 24 which discharges into a lowpressure port 17. The pressure to the right of the piston together with the load of a spring 21 opposes the outlet pressure acting on the piston, whereby the latter moves to throttle the ports 22 to a varying degree to maintain the outlet pressure constant. The pressure of the ball valve spring 26 is varied by rotation of a knob 34 fixed to a nut 31, retained by a snap-ring 33 in rotatable relation with the housing 6 and engaging a threaded portion of a spring- abutment 27 which is prevented from rotating by a radial pin 30 engaging a slot in the housing. For releasing the pressure to the right of the piston 18, and, therefore, in the outlet 23, a port 14 is provided, connected through a normally closed piston valve 37, Fig. 3, with the port 17. The piston valve is actuated, through a spring toggle mechanism, by.a pair of push-buttons, only one, 41, of which is shown. The device may be used as a pilot valve for supplying liquid under constant pressure to a supply and discharge valve 51 in a hydraulic system. The valve 51 comprises a piston valve member 50 centralised by springs 56, 57 and subjected at its left-hand end to the outlet pressure from the pilot valve and at its righthand end to the pressure in the system acting through a passage 62 in the valve member, the system being connected to a passage 63. Thus, should the system pressure fall, the valve member 50 moves to the right and admits pressure liquid from a supply passage 65, and should the system pressure rise, the valve member 50 moves to the left and exhausts liquid to a sump connection 64. In a modified arrangement, the valve 51 is used solely as a relief valve, and the connection 65 is not used.

Title: Methods and apparatus for drying oils by the evaporation of the water and for determining the solubility of water in oils
Inventor: HAKLUYTT JOHN PHILIP DABBS
IPC: F02B3/06
Filed: 1954-02-02
Abstract: Oils which are admixed with water (whether in the form of a mixture, an emulsion or a solution) are dried by causing the oil to form a spray in such a manner that a stream of air is induced into the spray, whereby the water vaporizes into the air and is removed therewith.  In the apparatus shown, tank 3 is provided with a sprayer 2 comprising a cone-nozzle having axial slots in the cone face; and two vents 5 and 6 are fitted in the dome of the tank on either side of the sprayer.  Liquid is pumped to the sprayer at high <PICT:0775097/III/1> pressure (e.g. 200 p.s.i.) by gear pump 1.  The sprayer is so inclined with respect to the vents that, when they are open, atmospheric air is drawn in vent 5 and discharged through vent 6. The top of the tank is connected to a manometer 7.  A baffle 4 is fitted at the mid-section of the tank, and a discharge cock 8 is provided at the base.  The liquid collects in the lower part of the tank, and is sucked out through cock 8 by pump 1, flowing thereto via cooler 13, which comprises a water-cooled jacket, and a filter (not shown).  The vent 6 may be connected to a condenser, e.g. an air-cooled, thin-wall copper tube.  In an example, diesel oil which initially contained 1.37 per cent water was circulated through the system at a temperature of 127 DEG F.  The oil was free from water after about 3 1/2 hours.  The apparatus may also be used for determining the solubility of water in oil, and for the rapid estimation of the water content in oil.  The method employed is the measurement of the increase in total pressure within the tank when oil is circulating through the system with both the vents closed, and introducing measured quantities of water into the system.  Graphical methods are employed to determine the saturation point and, by extrapolation, to find the condition of the oil at the commencement of the experiment.

Title: Improvements in or connected with indicating or control means for use in a synchronized system of film recording
IPC: G03B31/00
Filed: 1937-02-02
Abstract: 486,225. Recording sound in association with kinematography; desks. HOLT, S. C. Feb. 2, 1937, No. 3078. [Class 40 (ii)] [Also in Group XIV] In a system in which sound has to be recorded in synchronism with existing picture film the rate at which music &c. should be played is indicated by a control chart in conjunction with a timing means which may be a stop clock or a control film used to prepare the chart. The control film is first produced by means of an indicating device. This has a small dial 2b, Fig. 6, traversed by a hand 4 and divided into 24 spaces to represent each of 24 frames passing in a second, and a large dial traversed by a hand 3 and divided to represent 60 seconds. The pointer 4 is moved one division at a time, the pointer 3 being moved an appropriate amount and at each movement a single frame of the control film is exposed to photograph the two dials. Thus any single frame may be identified by the positions of the two pointers and if the film is run at normal speed the hand 3 makes one revolution per minute. The control film is compared, e.g. by optical projection, with a copy of the picture film and individual frames where certain sound effects commence or finish are identified by reference to the pointers. The times so obtained are transferred to the control chart 1, Fig. 2, which in addition to the musical score A bears a printed scale F to represent the passage of time. This scale has dials H, H<1>, H<2> representing the positions of a seconds hand at intervals of five seconds from zero, the intervening spaces being marked to represent individual seconds and each complete line representing the passage of ten seconds. The appropriate position of any individual frame is marked by use of a gauge 5 which, when placed between the desired seconds markings, gives 24 subdivisions 5a the required one of which is marked on the chart by a line N. The musical score (words &c.) is then written to coincide with these timing markings and when played is timed by a stop clock, initially set at zero, the rate of playing being such that at the end of each five seconds the position of the clock hand is the same as that of the relative indicator H on the chart. For actual recording, as distinct from rehearsal, the control film may be run through at correct speed, the movement of the seconds hand 3 being used for timing instead of the stopclock. A suitable control desk 6, Fig. 9, is fitted with a stopclock 7, controlled by a lever 8 by means of Bowden cable, a signalling bell push 12 and indicator lamps 11, 11a, the whole being arranged to shut up for transportation. Other dials to indicate the position of the clock hands at the commencement, end or other important times in the recording may be fitted to the sides of the clock casing, Fig. 13 (not shown).
