Title: Improvements in systems for recording variations in physical values
IPC: G01L19/08
Filed: 1923-01-10
Abstract: 191,737. Roucka, E. Jan. 12, 1922, [Convention date]. Tell-tale apparatus.-In a system similar to that described in Specification 191,735, in which the position of a pointer &c. is indicated &c. by the position of an impulse of auxiliary energy in a time interval, and in which the primary instrument has a movable member which is acted upon by a varying force as well as by the force to be measured, the impulse produces no reaction on the primary instrument. In apparatus for recording variations in density of a gas, the bell 12, Fig. 1, carried by a conical bearing on the arm 16 tends to rise and fall with variation in density of gas in the apparatus 6. A cam 48 driven by a motor 60 varies the tension of the spring 44. Normally, arm 16 is against the upper of the stops 22, but when a predetermined relative value of the forces due to the spring 44 and to the gas pressure is reached, the arm moves to the lower stop. An extension 24 is thereupon drawn by a rotating disc 30 between it and conducting strips 26 which are carried on a pivoted arm as shown in Fig. 2, so as to complete the circuit of a magnet 68. The disc 30 is periodically raised by a cam 40 to free the part 24. The recording mechanism comprises an arm 114 normally locked by an arm 98 and acted upon by a spring 112 which is being stressed by means of a cam 102 driven by motor 60, (or if the recording apparatus is at a distance by a motor running synchronously with motor 60), synchronously with the cam 48. At the instant magnet 68 is energized an impulse is sent out from a battery 66 through a switch mechanism 74, 76, 80, 82 to energize magnet 94 and so momentarily to free the arm 114. The recording arm 114 thereupon takes up a position in accordance with the positions of cams 102 and 48 at the moment arm 16 moved to the lower stop and therefore with the density of the gas. In a modification, Fig. 3, the rotating disc 30 is replaced by a rapidly reciprocating member 156 into the path of which extension 24 comes when lever 16 moves over so as to bridge two contact members 150. In a further modification, the arm 160, Fig. 6, corresponding to extension 24 is permanently connected to the circuit of magnet 68 and at the moment of movement, arm 160 comes :into the path of bristles 168 on a constantly rotating member 166 and completes the circuit through a conducting strip 164. The receiving apparatus may be at a distance and driven by a motor running synchronously with that at the transmitter. The Specification as open to inspection under Sect. 91 (3) (a) also refers to a commutator connected in series with the switch 74, 76 and magnet 94 and arranged to break the circuit during the return of the switch to normal to prevent a second release of the arm 114. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements relating to the control of the mixing of liquids
Inventor: BLIGHT FRANK CHARLES
IPC: G01N21/78
Filed: 1953-01-12
Abstract: The process of the parent Specification is modified for controlling a mixing process in which acid is added to an aqueous alkaline solution to render the solution acid.  Two samples of the mixture are taken and alkali instead of additional acid is added to one sample so that if the mixture is satisfactory this sample should become slightly alkaline and, therefore, of a different colour from the other sample in the presence of the colour indicator.  The method is applicable to the production of water of substantially constant acidity by blending alkaline water with acidic water.  The two samples may be used to control two photoelectric devices which operate relays by which the blending or other mixing proportion is corrected.ALSO:The process of the parent Specification is modified for controlling a mixing process in which acid is added to an aqueous alkaline solution to render the solution acid.

Title: Improvements in or relating to Paper or Stock Feeding Devices for Printing or other Machines.
Inventor: DOW WILLIAM JAMES
IPC: B65H3/34
Filed: 1917-01-19
Abstract: 112,798. Dow, W. J., (Harris Automatic Press Co.). Jan. 19, 1917. Pile tables for sheet feeds; sheet-separators.- In a sheet-feeding apparatus for printing or other machines, the top sheet is separated from the pile by a buckling-device comprising a sheet-holdiug member, a sheet-buckling member and a pile-retaining member all carried by a frame which is reciprocated vertically to operate the members in proper succession. As shown, a vertically reciprocating rod 13 carries at its lower end a pivoted frame 19 provided with a lug 20 forming a pile-retaining member, and a buckling- roller 21, preferably of rubber, secured against rotation bv a bolt and nut 23. A frame 24 pivoted to the frame 19 carries a steel sheetholding roller 25. The rod 13 falls by gravity and is raised by a cam 31 on a constantly rotating shaft 30, engaging a block 14 secured to the rod. A pin 15 secured to the block 14 engages a groove 17 in the fixed bracket 12 to guide the rod 13 and prevent its rotation. When the rod 13 is in its highest position, as shown in Fig. 2, the roller 25 is resting upon the pile and the roller 21 and lug 20 are raised. When the rod falls, the roller 21 engages the top sheet and then, by the swinging of the frame 19, moves towards the roller 25 and buckles the sheet until the lug 20 engages the pile behind the buckled sheet. The lug 20 then acts as a fulerum for the frame 19 during the rest of the downward movement of the rod 13 and the roller 21 is thereby raised clear of the sheet and, in rising, also lifts the roller 25 by the engagement of the bolt and nut 23 with the side arms of the frame 24. The sheet is fed off the pile by any suitable feeding-off mechanism. The pile table is raised in accordance with the height of the pile by ratchet and pawl mechanism operated by an oscillating shaft 29 carrying an arm 27 resting on the top of the pile. The arm is operated in unison with the buckling-device by a cam 32 on the shaft 30. The buclcling-device is arranged at one of the rear corners of the pile, and a second similar device may be arranged at the other rear corner.
